Abstract

PURPOSE:To improve operability when a copying mode is set after the designation of copying start is received by enabling the change of various kinds of copying modes by a mode change means even under a standby state after the designation of the copying start is received during the warming-up of a copying machine. CONSTITUTION:A mode selection key 3 is depressed and a mode is compared with the present mode. When there is the point of changing, the mode is changed. Next, the data of an A/D converter 11 is read and it is judged whether the temperature of a fixing heat roller is over set temperature or not. When it is not over, a print key is received. However, when it is over, the preparation of the copying is regarded to be finished. By constituting a controller 7 in such a way, the mode can be changed even after the standby state is attained by depressing the print key 1 after the mode for the copying is set during the warming-up of the copying machine. Thus, the copying machine having the excellent operability is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a control device for a copying machine, and more particularly to a control device for a copying machine that is characterized by copy start and copy mode setting.

[Conventional technology]

Conventional copying machines do not accept presses of the print I key (copy start button) during the warming-up of the copying machine (copy pre-#i), that is, when the temperature of the fixing roller is rising or the lens is moving. It was controlled like that.

However, with this conventional technology, the print key must be pressed again after warm-up is completed, which is time-consuming, and for users who are inexperienced with the operation, if the copying operation does not start after pressing the print key twice, There were some problems, such as people mistakenly thinking that the machine was out of order.
Even during warm-up, the print key does not work.
Techniques have already been proposed in which copying operations can be started immediately after warm-up (for example, in Japanese Unexamined Patent Publication No. 6
(Publication No. 1-247262, Japanese Unexamined Patent Publication No. 117569/1983
(Japanese Patent Application Laid-Open No. 62-287268, etc.).

[Problem to be solved by the invention]

By the way, the mainstream of copying machines is multi-function machines that allow you to select various copying modes, such as variable magnification, paper selection, sorting/stacking, etc., but conventionally, the copying machine is in a standby state after pressing the print key. However, in order to change the various copy modes, you must first use the clear key to cancel the standby state, set the various copy modes, and then press the print key again, which is a disadvantage of poor operability. was there.

SUMMARY OF THE INVENTION An object of the present invention is to provide a copying machine control device that can improve the operability of copy mode settings after receiving a copy start instruction.

[Means to solve the problem]

The above purpose is to provide a means for instructing to start copying, a means for setting a copying mode, a means for storing information when a copying start is instructed and a copying mode is set, and a means for storing the information when copying start is instructed and a copying mode is set, and a means for copying when copying preparation is completed. If the start instruction is stored, in a copying machine that has a means for starting a copying operation and a means for storing a program for performing the above operation, even if the copying machine is preparing for copying and after the instruction to start copying has been issued. This is achieved by providing a mode changing means that can change the copy mode.

[Effect]

The mode changing means makes it possible to change various copying modes even in a standby state after receiving an instruction to start copying during warm-up of the copying machine.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

FIG. 1 is a control block diagram of a copying machine according to an embodiment of the present invention.

In the figure, ■ is a print key for accepting the start of copying, 2 is a display device for displaying whether copying is possible, and 3 is a key for selecting copying modes such as copying magnification, paper size, paper ejection mode, etc. , one or more mode selection keys, 4 print key 17 display device 2. T1 for exchanging the signal of the 1000'-code selection key 3 with the CPU 7
0 is an interface, 5 is a ROM in which programs for performing operations necessary for controlling the present invention and a series of operations necessary for copying, which will be described later, are stored, and 6 is a memory for remembering that the printer key 1 has been pressed. , a RAM for storing temporary information necessary for a series of copying operations, 7 a CPU for executing judgment and control in this embodiment, and 8 a CPU 7 for receiving data between each sensor, driver, etc. and the CPU 7. T10 interface for transferring, 9 a paper sensor for detecting the presence or absence of paper, 10 a toner sensor for detecting the presence or absence of toner, 12 a temperature for measuring the temperature of the fixing heat roller. A sensor 11 is an A-D controller 7 that converts the temperature data of the temperature sensor 12 into digital temperature data, 14 is a motor for moving the lens that determines the copying magnification, and 13 is a motor 14 connected to the T10 interface 8. This is a driver that operates based on data.

Next, the control operation according to one embodiment will be explained based on the flow shown in FIG. 2.

When the power switch is turned on, the CPU 7 checks the data of the paper sensor 9 and the toner sensor 10, and determines whether there is paper or toner (5IS2), and if YES, the process proceeds to the next step. Then, the green LED in the display device 2 is turned on (S3) to prompt the user to press the print key 1.

This display device 2 has built-in LEDs of three colors: green, yellow, and red, and is configured to be turned on by a command from the CPU 7.

Next, if FPtNT on the RAM 6 is not 1, that is, if print key 1 is not pressed (N in S4), proceed to the next step, and when print key 1 is pressed (Y in S5),
1 is stored in FPRINT on RAM6 (S6),
It is recorded 41 that the print key 1 has been pressed. At the same time, the green LED of the display device 2 is turned off and the yellow LED is turned on to indicate that the pudding 1 to key 1 have been pressed (S7).

Next, when the mode selection key 3 is pressed (Y at 38), the mode is compared with the current mode, and if there is any change (Y at S9), the mode is changed (310).

Next, the data Ts of the A-D controller 11 is read, and it is determined whether or not the set temperature To of the fixing heat roller has been exceeded (S
ll). If it has not exceeded the limit, go back and accept print key 1, but if it has exceeded the limit, it means that copy preparation is complete. At this time, print key 1 is pressed while warming up.
If FPRINT indicating that is pressed is 1 (Y in S12), immediately turn off the yellow LED of the display device 2, turn on the red LED indicating that pressing the print key 1 is invalid, FPRTNT is cleared (313, 314) and copying is started (317). If FPRINT is 0 (N in S12), wait until print key 1 is pressed (S15
), when pressed, turns off the green LED and turns off the red L as above.
f & turns on ED (S16), starts copying operation (31
．． 7).

By configuring the control device to perform the above series of operations, the operator sets the mode for copying during the T-forming up of the copying machine, then presses the Print 1-key 1 and the machine goes into standby mode. You can still change the mode for copying.

Next, a flowchart will be described in which the above-described operations are applied during lens movement when changing the copying magnification.

FIG. 3 shows the flow of scooting from when the copying machine is in the standby state after warming up. First, it is determined whether copying is possible by detecting the presence of paper, the presence of 1-ner, etc. (520), and if it is prohibited, processing such as turning on a warning lamp is performed (S21), thereby making it possible to make copies. If so, the green LED of the display device 2 is turned on (S22).

Next, if print key 1 is pressed (N in S23, S2
(Y in 4), 1 is stored in FPRINT on the RAM 6 (S25), and it is recorded that 1. Mark.

Next, when mode selection 10-3 is pressed (Y at 326),
If the magnification is changed (Y in S27), turn on the motor 14 for moving the lens (528), or if there is another mode change (
(Y in S29), the mode is changed (S30). If the mode selection key 3 is not pressed here (N at 826), the motor 14 is not turned on and the process returns to the loop in which the press of the print key 1 is accepted (S31). While the motor 14 is running (
(Y in S32), if pudding 1~key 1 is not pressed,
After the motor 14 moves the lens to a predetermined position (S3
3), turn off (S34).

However, even if the print key is pressed (Y in S31),
Since it is impossible to start copying immediately while the motor is moving (Y in S35), the green LED of display device 2 is turned off, the yellow LED is turned on (S36), and print key 1 is pressed. This is indicated to the operator and waits until the lens movement is completed (Y at S37, 538).Then, the yellow LED of the display device 2 is turned off, the red LED is turned on (339), and the copying operation is automatically started. (S40). Even after pressing the print key 1 while the lens is moving, if the mode selection key 3 is pressed, the mode for copying can be changed.

Furthermore, if the print key 1 is pressed while the lens movement motor 14 is off, the green L
After turning off the ED and turning on the red light, the copying operation begins.

〔Effect of the invention〕

As explained above, according to the present invention, the copying mode can be easily changed even after the machine enters the standby state by pressing the Print 1 key during warming up, and the copying machine has excellent operability. can be provided.
