INTRODUCTION



There was a time when business used to be small and the total number of
employees used to be quite a few. The office appliances were regarded
merely as luxury. With the expansion of business, there has been a great
development in the use of office appliances and labor saving devices,
which have been introduced to save time and manpower. These machines can
do the job more speedily, accurately and at lower cost. In fact, they
have become a necessity for smooth and efficient working of the office.
Labor saving devices can be classified into the following three groups:



A. General Machines



B. Communication Machines



C. Accounting Machines





A. GENERAL MACHINES



1. TYPEWRITER



It is a common machine and is used in each and every office, as time and
labor saving devices. Through this machine, many letters and documents
can be typed with speed and neatness. It can prepare more copies in no
time. As the industry advanced and requirements increased the
improvement in typewriting machines have also been made. Noiseless
typewriters are used where typists work near executives and other clerks
as noise is likely to cause disturbance. Electric power is also used
for operating typewriters. Electric machines require less human exercise
and can type more copies than the ordinary machines of typewriter. This
is more liked by a typist as he gets less tired and maintains his
output better than he does by an ordinary machine. Electric typewriters
are more expensive and cannot be used in small offices.





2. DICTATING MACHINES



There are a number of dictating machines but they are all based on same
principles on which the gramophone works. These machines record the
dictation given by the office executive who can be transcribed by the
audio typists and thus, the presence of stenographer is not necessary.
These machines however, usually consist of three machines the actual
dictating machine, the transcriber and the shaver. The first is used by
the person for dictating. The second on e is used by the typist an the
third machine is used fo9r shaving of the dictated matter. This machine
is most useful for secretaries, partners, managers and others who rare
subject to frequent interruption. With special attachment, the dictating
machine can be connected so as to record telephone, messages and by the
use of microphones, it can also be used for recording speeches.





3. DUPLICATORS



When 100 of copies are required the duplicating machines are used. Each
class of machine has its advantages and in selecting a machine for use
in particular office, these advantages should be be Given consideration.
A variety of duplicators are in use nowadays and few of them are given
below;





A) SPIRIT DUPLICATOR



These duplicators can reproduce typewriting, hand-writing or drawings in
a variety of colors. A master copy is prepared on a sheet or art paper
by means of hectograph carbon paper. This is the only type of machine
which can reproduce in several colors in one run. According to the
quality of paper and carbon paper used, 100 to 250 copies can be made.





B) STENCIL DUPLICATOR



These duplicators can reproduce type writing .the stencil is out either
on typewriting or by writing or drawing with a special pen. Up to 4,000
copies can be obtained and stencils can be stored and re –used if
carefully handled and protected.





C) OFF SET LITHO DUPLICATOR



These duplicators can re-produce typewriting, hand writing and drawing.
As in the case of stencil, different colors can be reproduced on the
finished copy. Up to 50,000 copies can be obtained from the machine.





D) TYPESET DUPLICATOR



These machines are in fact, small printing press of letter press type.
It is a sloe method and it also requires some skills to do job. Up to
500,000 copies may be printed.





4) ADDRESSING MACHINE



This machine is bit different from the duplicators .these machines are
generally used for addressing the envelope to the regular clients or for
the preparations of labels. These machines are adaptable enough to take
the wide variety of other work in the office .These machine are
operated by electric power.



In this machine, addresses are embossed on metal plates or are stenciled
on specially prepared fiber material. These plates are placed
alphabetically or in any other manner. When the actual addressing work
is t be done, these plate are placed and passed through the machine, and
the address are printed on the envelopes.



5) CASH HANDLING MACHINE



The work of the cash department can be helped considerably by machines
for handling coins. There are machine for sorting out coins of different
denominations from a mixed heap of coins and appliances are also
available for counting them. There are also machines for giving change
quickly. As no mental calculation is necessary, a great saving of time
is affected by such a machine where the number of transactions is very
large.





6) CASH CHECKING MACHINE



There are number of appliances which may be used to check automatically
the receipts of cashiers. They are usually known as cash registers. Some
of them also have arrangement for adding up the receipts so that at any
time the machine shows the total cash that should be in be the cash
drawer attached to the machine. Some are also so constructed as to issue
the receipts to customers while keeping the record for the office.





7) FRANKING AND STAMP FIXING MACHINE



Franking machine saves a good deal of time in scaling the letters and in
getting ready for the mail. This machine makes an impression on the
envelopes showing in red ink the amount of the postage and the place of
origin and date of posting. No postal stamps need to be used. The
machine have matters attached to them and they are locked and sealed by
the postal authorities to frank up the amount after which the machine
gets automatically locked. Some of these machines also have an automatic
envelope scaling device. Some business houses have the stamps affixing
machine which are fed with postage stamps, and there are devices to cut
the stamps off, to moisten and affix them and to count them.





8) TIME RECORDING MACHINE



These machine records the time of arrival and departure of the employees
of he office. These type of machine is used in the office where payment
are made on the basis of time spent on the job. This machine is like a
clock and when the employee enters the office he cuts card in the
machine which prints the time. Similarly when he goes out, further he
cuts the card in the machine and departure time is printed on the card.

B) COMMUNICATION DEVICES



1) TELEPHONE



The use of telephone is so common and all its importance is so well
known that it does not need further explanation. It is maintained by
high business houses internally and externally. Internal system enables
the executives of same organization to talk to each other on telephone
whenever they need so. External systems enables them to talk outside
parties. Every city is linked by telephone system so that through trunk
call any one may have talk anywhere in the country with the required
person.





2. RADIO-TELEPHONY



It is a system which link by telephone mobile vehicles in city or may be
in an area. This system is in advance countries. Under this system
mobile units such as cars, vans, etc can control each other on
radio-telephony through the central station located in the city.





3. PUBLIC ADDRESSING SYSTEMS



In big factories, shops and offices this system is a useful means to
give instructions to all of the employees or only those particularly
concerned with any special instruction. This system has an advantage of
quick communication of message to the concerned persons but it has also
the disadvantage of distributing all of the employees while instructions
are concerned with any particulars employee.





C. ACCOUNTING MACHINES



1. ADDING MACHINES



After typewriter, adding machine in perhaps the most commonly used
machine in office routine working. Adding machine is basis for all
further calculations. These machines are of two type: listing and
non-listing. These machines have following advantages:



1. Cross-casting is much further faster. Most clerks, unless they are
very highly skilled, cannot add horizontally with the same speed as they
can add vertically.



2. Selected items can be added from different documents or from scattered positions in one document.



3. Less skill and concentration are required by the clerk.



4. With the aid of adding machines, junior clerks can add with speed and accuracy equal to or exceeding that of a skilled clerk.





2. CALCULATING MACHINES



In a large business there is a lot of calculation work, in order to
asses the position. In calculation various forms such as addition,
subtraction, multiplication and division are involved. There is
likelihood of accounting mistakes, and takes more time in corrections.
Keeping in view both the important factors time as well as accuracy
nowadays the calculation work is carried on through calculation
machines. With the help of calculating machines addition, subtraction,
multiplication or division can easily be made with accuracy and without
loss of time. Apart form this with the help of said machine the problems
of exchange, discount etc. can be solved with great accuracy. It does
not require any special training to operate the machine, the mistakes
can only occur when the machine in question is not properly handled or
when out of order.





3. POSTING MACHINES



Posting means the transfer of amounts from original entries to the
appropriate ledger accounts. Accuracy of entries and easy to read are
the most important requirements of this function. These machines play an
important role in maintaining the accuracy.





4. ELECTRONIC COMPUTERS:



The computers operate at the fastest speed which ever is thinkable by
human mind, because these machines do not depend on mechanical movements
but on electronic pulses with duration of about one millionth of a
second. Computers are able to perform the following functions:-



1. Receive a programme of orders representing the routing to be carried out, store this and refer to it as may be required.



2. Take in original information through one or more input channels and store it for reference as required by the programme.



3. Perform any arithmetical calculation as and when required by the programme.



4. Store the result of any calculation for further reference and accumulate totals as required by the programme.



5. Select any information from the store, arrange it in any required
sequence and discharge it through one or more output channels to be
printed punched into cards or paper tape, or recorded on.



Apart from computer speed, the principal characteristic of electronic
computers is their flexibility as would appear from the following:-



1. They can be made to carry out any electrical operation only by feeding in the appropriate orders.



2. They can proceed from one kind of operation to another automatically.



3. They can automatically select alternative courses of action according
to the nature of the date received or the results of previous
operation.
