Abstract
Abstract A copying machine has a microcomputer which is capable of actuating a plurality of processing components, including an automatic document feeder, a semi-automatic document feeder and a sorter, to continuously perform automatic copying with time sequence. This microcomputer has a random access memory. In the random access memory (RAM) are stored a series of programs for continuous copying specified at a keyboard by a user, that is, copying conditions such as a copying sheet number, modes of enlarged copying, reduced copying and copying of equal size, selection of an outfeed position of the sorter, selection of the automatic document feeder or the semi-automatic document feeder, and changes in paper sizes. The microcomputer controls respective components of the copying machine so as to perform continuous copying in response to the program stored in the RAM.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
153 words
A control device of a copying machine wherein said control device is capable of actuating a plurality of processing components, including an automatic document feeder, a semi-automatic document feeder and a sorter, to continuously perform automatic copying with time sequence, comprising: (A) means for setting copying conditions, including selection between said automatic document feeder and said semi-automatic document feeder, and a copying sheet number, based on the copying conditions; (B) memory means for storing the copying conditions and the copying sheet number set by said setting means in correspondence with each other; (C) means for judging if the number of copies produced has reached the copying sheet number which is stored in said memory means; and (D) control means for reading out a copying condition from said memory means according to judging results obtained by said judging means, and including means for executing a copying operation based on said read out copying condition.
Claim 2
Dependent Claim
153 words
A control device of a copying machine wherein said control device is capable of actuating a plurality of processing components, including an automatic document feeder, a semi-automatic document feeder and a sorter, to continuously perform automatic copying with time sequence, comprising: (A) means for setting copying conditions, including selection between said automatic document feeder and said semi-automatic document feeder, and a copying sheet number, based on the copying conditions; (B) memory means for storing the copying conditions and the copying sheet number set by said setting means in correspondence with each other; (C) means for judging if the number of copies produced has reached the copying sheet number which is stored in said memory means; and (D) control means for reading out a copying condition from said memory means according to judging results obtained by said judging means, and including means for executing a copying operation based on said read out copying condition.
Claim 3
Dependent Claim
37 words
A device according to claim 1, wherein said copying conditions includes copying modes such as enlarged copying, reduced copying and copying of equal size, selection of an output position of the sorter, and changes in paper sizes.
Claim 4
Dependent Claim
145 words
A device according to claim 1, said control means includes a programmable microprocessor connected to said setting means, said memory means and said judging means; said microprocessor including a central processing unit which receives an input signal for interruption copying and a read-only memory device which stores a permanent program; and said read-only memory device having a permanent program for said central processing unit, so that said control means may perform a specific operation in accordance with the program, whereby when the input signal for interruption copying is received, said automatic document feeder, said semi-automatic document feeder and said sorter are controlled to stop the document feeding of said automatic document feeder, to feed a document to be copied in the interruption copying mode by said semi-automatic document feeder and to specify to feed out a produced copy to a preselected section of said sorter.
