[Prior Art] Regarding a copying machine capable of setting magnification, there is a technique disclosed in Japanese Patent Application Laid-Open No. 58-217947.

This technology switches the variable magnification copying mode of a copying machine by operating a single operation button, displays the magnification ratio set by the switching, and
After a predetermined period of time has elapsed after the operation of the operation button, the optical system starts to move to a predetermined position according to the magnification ratio based on the setting of the operation button, and after this arrangement is completed, copying is started. The market is based on things that perform actions.

Therefore, for the optical system that starts moving to a predetermined position according to the magnification after operating the operation button, it is recommended to set the time limit for the optical system to start moving long enough to correct any operational errors. , the optical system can be moved only once.

[Problem to be solved by the invention] However, in the normal variable magnification copy mode, the key arrangement or rotation is set so that each key or optical system can cope with reduction, enlargement, and same magnification with the minimum displacement. . Therefore, even if a magnification error occurs due to a key operation error, the probability of the optical system changing drastically from the minimum reduction magnification to the maximum magnification, or from the maximum magnification to the minimum reduction magnification, is actually low. few.

On the other hand, in devices such as the copy mode program selection device of a copying machine, in which the user stores frequently used copy modes in memory and calls them up as needed, the contents of the memory are stored. In some cases, the optical system must undergo extreme displacement from the minimum reduction magnification to the maximum enlargement magnification, or from the maximum magnification magnification to the minimum reduction magnification, and even when selecting a tray in duplex copy mode, the copy mode program selection device may It may operate depending on the contents of the selected memory.

As described above, if the key operation of the copy mode program selection device of the copying machine is incorrect, there is a problem that even if the key operation is corrected, the setting cannot be made until the mechanical drive part is displaced again. As a result, there was a problem that there was a delay in setting the desired copy mode. Further, the mechanical parts of the copying machine may move unnecessarily, shortening the mechanical life of the R mechanism or causing trouble.

Therefore, the present invention has been made to solve the above problems.Even if an error occurs when calling the copy mode program, it is possible to correct the copy mode to the desired one and shorten the time required to perform the copy operation.

[Operation] In the present invention, a plurality of copy modes desired by the user are stored in a memory by the copy mode program control means, and selected and recalled by key operation to display them. The copy mode called up and displayed by the time limit setting means by key operation is set after a certain period of time has elapsed since the time limit setting means sets the displayed copy mode as the mode for performing the copy operation selected by the user, and the time limit setting means sets the displayed copy mode as the mode for performing the copy operation selected by the user.

shall be.

Note that the second microcomputer CPU2 starts an exposure scan upon receiving the signal.

When the optical system 2 is at the predetermined position in step 373,
The timing signal output from the second microcomputer CPU2 is determined. The timing signal 111
When I+ is detected, the clutch of the timing roller 43 is turned on in step 374, the copy paper is fed between the photosensitive drum 30 and the transfer charger 37, and transfer to the copy paper is started. Also,
Timer TC is started. Note that the timer C is a timer for setting the operation end time, the charging time, and the Δ time of the clutch of the timing roller 43, and the set time is based on the size and setting of the copy paper selected in steps 365 to 368. Determined by the copy magnification.

In step 375, it is determined that the timer TC has ended, and when the time limit set in the timer TC has elapsed, step 376

, the clutch of the timing roller 43 is turned off. Then, in step 377, the second microcomputer CPU
It is determined whether the return signal output from 2 is li 1 I+.

When the return is started and the return signal is 7111+, it is determined in step 378 whether the multi-copy is finished, and when it is determined in step 380 that the optical system 2 has returned to the reference position, the output is output from the second microcomputer CPU 2. Step S
At step 81, the developing motor M4 of the carrier 31 and the transfer charger 37 are turned off, and the timer TD is set. On the other hand, if the multi-copy is not completed, the copy start flag is set again in step 379 (set to 111 I+). Then, at step 382, the main motor M1 is turned off, and at step 383, the main motor M1 is turned off, and at step S

At 85, each control signal of the external device is output. In this way, a copy operation is performed.

In the above embodiment, when the copy mode program call key 867 is operated for the first time, the first memory display LE
The first memory corresponding to D867a becomes the second memory corresponding to the LED 867b for displaying the second memory in the subsequent operation.
Then, in a subsequent operation, a copy mode display in an auto-clear state that is not related to the first memory and the second memory, that is, standard copy mode information is selected. However, when executing the "program call routine" of the above embodiment, when the copy mode program call key 867 is pressed for the first time, the current copy mode is stored in a specific memory, and the copy mode is stored in the first memory and the second memory. It can also be configured to select it when it is not selected.

-26= In this way, the copy mode program selection device of this embodiment stores a plurality of pieces of copy mode information preset by the "copy mode writing program routine" in the memory, and selects them by operating the keys. The copy mode information that was called and displayed by key operation in the "program call routine" is selected after a certain period of time set in the program timer has elapsed since the call. This mode performs the processing to set the mode.

In the past, even if you made a mistake in key operation of the copy mode program call key of the copy mode program selection device, if you corrected the key operation within a certain period of time set by the program timer, the mechanical drive part would be displaced again. Since it is not necessary, the time limit set in the program timer allows
As a result, it is possible to modify the copy mode to the desired one and perform the copy operation quickly.

Furthermore, the number of times the magnification setting motor M3 moves the lens 25 of the optical system 2 of the copying machine needlessly can be reduced. Naturally, it is also possible to reduce the number of drives of the tray selection mechanism when performing double-sided copying, which is not disclosed in this embodiment. Therefore, the mechanical parts move unnecessarily,
It can shorten the mechanical life of the mechanism and prevent trouble from occurring.

In particular, when a memory is provided that stores multiple pieces of copy mode information that are selected in rotation by key operations, when selecting a predetermined memory, the memory that stores unnecessary copy mode information is called up, and then the desired copy mode is selected. Until the memory in which the information is recorded is selected, mechanisms such as the lens 25 must be driven by the magnification setting motor M3 of the copying machine, but this is avoided in the above embodiment.

By the way, the copy mode program control means for storing a plurality of pieces of preset copy mode information in the memory, selecting and recalling them by key operation, and displaying them in the above-mentioned embodiment is called "Copy 17 Write However, when implementing the present invention, a plurality of pieces of copy mode information are stored in memory by key operations, and a key operation corresponding to the plurality of memories or a single key operation is used to carry out the present invention. It is sufficient that the memory selected by rotation can only be written to and read from.

Further, the time limit setting means for setting the displayed copy mode information as the selected copy operation mode after a certain period of time has elapsed since the call-up of the copy mode information called up and displayed by the key operation in the above embodiment is as follows.
A program that sets the displayed copy mode information as the selected copy operation mode after a certain period of time set in the program timer has elapsed since the call using the program call routine. However, when implementing the present invention, the copy mode information called up and displayed by key operation is displayed after a certain period of time has elapsed since the calling.
Any device may be used as long as it can determine the displayed copy mode information as the selected copy operation mode and control the copy operation.
