Abstract

PURPOSE:To easily set a complicate image formation mode again by setting the image formation mode again with a mode call key. CONSTITUTION:The whole of a copying machine is controlled by a CPU17 and the processing program for the control is stored previously in a ROM18. A storage area MODE where copy modes are stored is assigned in a ROM19. A counter CNT starts counting the time at the end of a copying process and the copy mode which is executed in the last copying process is stored when the counter enters a time-up state. With the mode call key of an operation part 22, the copy mode stored in the mode storage area MODE is read out and set again.

Description

DETAILED DESCRIPTION OF THE INVENTION (Al Industrial Field of Application) The present invention relates to an image forming apparatus that resets an image forming mode including paper size etc. after a certain period of time has elapsed.

(b) Conventional Technology In copying machines and the like, copying modes (image forming modes), such as the number of copies and image magnification, are set by operating keys from the operating section of the copying machine body. These copy modes can be operated by keys from the operation section, and the current mode can be displayed. therefore,
If you perform the copying process after confirming the display on this operating section, there will be no chance of a copying error. However, if you are in a hurry, you may neglect to check and often make mistakes in selecting the copy mode.

Therefore, a function is provided to reset the copy mode to a commonly used mode if a certain period of time elapses without the next copy process being executed after the copy process.

For example, the copy process is reset to a commonly used copy mode, such as doubling.

(Problem to be solved by the C1 invention: As mentioned above, the copying process is not executed and the copying mode is reset to the general mode after a certain period of time has elapsed. If for some reason you are away for more than a certain period of time, the 1!i complex copy mode will be reset to the general mode, and you will have to reset all copy modes to the complex mode when you copy again. It was very troublesome.

This invention was made to solve the above-mentioned problems, and even if copying is temporarily stopped in the middle of copying in a complicated mode and a certain amount of time has elapsed, simple operations can be performed. Another object of the present invention is to provide an image forming apparatus that can perform copying in the complicated mode.

+d1 Means for Solving the Problem This invention provides that when a certain period of time has elapsed after the image forming process without being executed and the image forming mode is reset, the image that was set immediately before is reset. An image forming mode storage means for storing the forming mode is provided, and a mode call key is provided on the operation unit, and means for resetting the image forming mode stored in the image forming mode storage means when the mode call key is operated. It is characterized by having been established.

fe) Effect In this invention, the image forming mode immediately before the image forming mode is reset is reset by simply operating the mode call key. Leave the image forming device with
Even if the complicated image forming mode is reset during that time, the complicated image forming mode can be reset by simply operating the mode call key.

(fl Embodiment FIG. 2 is a plan view of the operation section of a copying machine which is an embodiment of the present invention. Paper selection key 12 for selecting whether to feed paper from the paper feed cassette.
Magnification selection key 13° for selecting the magnification of reduction or enlargement for the original; Exposure selection key 14 for selecting the intensity of image density by adjusting the intensity of exposure. Numeric keypad 15 for setting the number of copies etc. A print switch 16 and mode call key 11 are provided for starting the copying process.

FIG. 3 is a block diagram of the control section of this copying machine. The overall control is performed by the CPU 17, and its processing program is stored in the ROM 18 in advance. When this program is executed, RAM 19 is used as a working area. A 110 port 20 inputs and outputs signals to and from the operation unit 22 via the drive array 21. Further, a counter CNT is assigned to the RAM 19, and when the copying process is completed, time is counted from that point onwards. Furthermore, a mode storage area MODE for storing a copying mode (image forming mode) is allocated to the RAM 19.

This area MODE is the counter CN
The copy mode that was being executed in the previous copy process when T times up is stored.

FIG. 1 is a flowchart showing the operation of this copying machine. A step-by-step explanation will be given below.

When the copying machine is turned on, all modes are initialized (nl). Paper selection key 1 of the operating section 22 shown in FIG.
2 and the magnification selection key 13 (n2), and when the print switch 16 is turned on (n3), the copying process is started (n4).

When the copying process is completed, the counter is turned on (n
5).

If the key (n6) or the print switch is not turned on (nl) during the next 2 minutes, the counter will time up (n8) and the number of copies in the paper cassette mode, magnification selection mode, and R output mode at that time. Store the mode, etc. in the RAM 19. n9) Reset the copy mode to the general copy mode (nlo). After this, when the mode call key 11 is turned on (n 11),
The copy mode stored in the RAM 19 is called up and the mode is sent to each paper cassette, magnification lens, etc. (n12).

As described above, when a certain period of time has passed after the copying process is completed, the copying mode at that time is temporarily memorized, and when the mode call key is turned on afterwards, the memorized copying mode is called and the paper cassette, magnification lens, etc. Since the mode is selected, even if you leave the place for more than a certain period of time while copying in a complicated mode, you do not have to worry about operating the selection key, which has the advantage of good operability. Further, the copy mode is automatically stored after a certain period of time has elapsed, and the pre-reset mode is called up simply by turning on the mode call key, so there is no need to take the trouble of storing the copy mode.

(E) Effects of the Invention According to this invention, even if the image forming mode is reset after a certain period of time has passed after the end of the image forming process, the image forming immediately before the reset can be resumed by simply operating the mode call key. Since the mode is already set, when it is desired to form an image in the mode immediately before the reset, there is no need to change the mode, which has the advantage of improving operability.
