Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control device for a copying machine, and more particularly, to a resetting time of various operation modes from one input means in a copying machine, and each time is individually managed. The present invention relates to an operation mode reset device which can be used.

Prior art Copiers include ADF mode, SADF mode, sort mode,
There are models that can set various operation modes related to a copy function such as a stack mode.

The setting (setting) of each operation mode is generally performed by a switch operation, and the resetting (setting release) is performed by the switch operation again and automatically after a lapse of a predetermined time after the end of the copying operation. There is one that is executed.

By the way, in a model that automatically executes the reset, several types of fixed time data are provided stepwise as a time until the reset is performed, and a method in which an operator selects according to the use frequency of each operation mode. Has been adopted.

However, when such a method is adopted, the reset time can be selected only within the range of the time data set in advance on the copying machine side, and all the operation modes set by the selected reset time are selected. Are reset all at once, and depending on the use mode of the copying machine, the resetting of each operation mode may take too fast or the time until resetting may be too long, which causes inconvenience in time management.

Objective The present invention therefore enables an operator to arbitrarily set each reset time of a plurality of operation modes,
It is an object of the present invention to enable flexible management of a reset time according to a use mode of a copying machine.

Configuration The basic configuration of the present invention is shown in FIG.

FIG. 1 shows an operation mode reset device of a copier capable of setting a plurality of operation modes related to a copy function such as an ADF mode, a SADF mode, a sort mode, and a stack mode.
1 is a designation means for designating a storage area for reset time data of the operation mode, 2 is an input means for inputting the reset time data, and 3 is a plurality of time data storage areas. Storage means for storing time data in a storage area designated by the designation means 1;
Is a timer for counting the time after the end of the copying operation, 5 is a time (T) counted by the timer 4 and each reset time data (Ti; i = 1, 2,..., X) stored in the storage means 3. And 6 is a comparison means for comparing T ≧ Ti
This is an operation mode control means for resetting the operation mode corresponding to Ti in the case of.

In the above configuration, first, when there is an instruction to set a certain operation mode Mi from the operation mode setting means 7 such as a switch,
The operation mode control unit 6 sets the copying machine main unit 8 in its operation mode.
Set to Mi.

Here, the operator inputs the operation mode from the specifying means 1.
An instruction to specify a reset time for Mi is issued, but the instruction also serves to specify a storage area in the storage unit 3. The operation mode setting means 7 and the designation means 1 may be combined so that an instruction to instruct a reset time is executed simultaneously with the setting of the operation mode Mi.

Next, when the reset time data Ti of the operation mode Mi is input from the input means 2, the data Ti is stored in the storage area of the storage means 3 specified above.

The above process can be executed for a plurality of operation modes. The reset time data Ti of each operation mode Mi is sequentially stored in the specified storage area of the storage unit 3 by operating the designation unit 1 and the input unit 2.

As a result, the reset time Ti is stored in the storage means 3, and when the copying machine main unit 8 in the normal copying operation state ends the copying operation, the timer 4 starts counting time, and the comparing means 5 sets The time T counted by the timer 4 is compared with the reset time data Ti in each storage area of the storage means 3. Here, when the comparison result of the comparison means 5 becomes T ≧ Ti,
After confirming this, the operation mode control unit 6 controls the copying machine main unit 8 to reset the operation mode Mi corresponding to Ti.

Therefore, according to the apparatus of the present invention, an arbitrary reset time can be set for each of various operation modes through one reset time input unit including the designation means 1 and the input means 2, and these reset times can be set after the end of the copying operation. When elapses, the operation mode corresponding to each time can be reset.

Note that the counter display C1 is used as a copy set number display in the standard mode, but is used as a display of the time (hour) data when the reset time is input, and the counter display C2 is used as the copy in the standard mode. It is used as a display of the number of sheets to be executed, but when a reset time is input, it is used as a display of the time (minute) data.

FIG. 3 is a system circuit diagram mainly showing the operation mode reset device of the copying machine according to the present embodiment, and is configured as a microcomputer control circuit.

In the figure, 30 is a ROM storing a system operation program of the copying machine, and 31 is a nonvolatile RA storing each management data.
M and 32 are I / O ports, which are connected to the bus 34 of the CPU 33, and the I / O port 32 has the above-mentioned various keys and indicators, and various drive motors and supplies for the main body of the copying machine. A control line 35a to a copying machine load 35 such as a paper clutch, and a relay 37 for turning on / off a switch 36 of a power supply circuit for the copying machine load 35 are connected, and access and I / O of the RAM 31 are performed.
For each external device connected to port 32, CPU 33
Is read out and executed.

The RAM 31 has a memory number memory section, a time display memory section, a time memory section accessed by memory numbers 0 and 1, respectively, and two timers for counting time by turning on / off a flag based on the clock of the CPU 33. Part (timer
1, a timer 2) and a digit counter are provided as independent storage areas.

In the above configuration, a reset time setting process and a timer counting process will be described with reference to FIGS. In this embodiment, reset time data for an operation mode (hereinafter, referred to as "auto mode") relating to any one of the copy functions of ADF, SADF, sort, and stack modes, and no operation is performed after the end of the copy operation. The power supply to the copier is cut off after a certain period of time without turning on (the power is turned off). The time data until the power is turned off in the auto shut-off function is set, each is counted, and the auto mode reset / auto shut is performed. The case where the control is turned off will be described as an example.

FIG. 4 is a flowchart showing the reset time setting process. First, when the time set key 14 is turned on, the memory number input mode is set from the standard mode state [steps (1) and (2)]. Where the numeric keypad
When the "0" or "1" key 12 is pressed, the input number data is stored in the memory number memory of the RAM 31 [steps (3) and (4)]. Here, it is assumed that "0" of the ten key input is input when setting the auto mode reset time, and "1" is input when setting the auto shut off time.

At this stage, the data already stored in the time memory of the RAM 31 corresponding to the input number is read and displayed on the counter indicators C1 and C2 [Step (5)].
(6)]. Here, the operator operates the counter indicators C1 and C2.
After confirming the already stored auto mode reset time or auto shut off time, if it is acceptable to turn on the enter key 15 and reset the memory number input mode, the data is held as it is [Step ( 7) (8)] On the other hand, if the data needs to be changed, the time set key 14 is turned on to reset the memory number input mode and set the time input mode [steps (7), (9) ( Ten)
(11)].

As a result, the time input enabled state is set. Before that, it is checked whether or not the digit counter for the time display memory of the RAM 31 is 0. If not, the digit counter is set to 0. 0000 is set in the time display memory [steps (12), (13), (14)].

Time data is input from the numeric keypad 12 four times in total, but the numeric data input each time the numeric keypad 12 is operated is stored in the time display memory while being sequentially shifted from the first digit to the fourth digit. Counter display with going
Displayed on C1 and C2, the digit counter is incremented by +1 each time an input is made [steps (15) to (20)].
That is, 21a → 21b of the counter indicators C1 and C2 in FIG.
The data entered in the order of → 20a → 20b will be displayed,
The value displayed on the counter display C1 indicates "hour" and the value displayed on the counter display C2 indicates "minute", and the time display memory naturally stores those data. become.

When the digit counter counts 4, the time input is completed, but the operator confirms from the counter indicators C1 and C2 whether or not the reset time is sufficient, and turns on the enter key 15 if the time is sufficient, If it is necessary to reset the time to another time, for example, due to an error during input, the clear key 13 is turned on and the process from step (13) is repeated again [steps (20), (21), (22) ].

When the enter key 15 is turned on, the time data in the time memory corresponding to the input number stored in the memory number memory is rewritten to the time data in the time display memory in step (4), and the time input mode is reset. [Steps (23) and (24)], thereby returning to the standard mode.

As a result, in step (3), when “0” is input, the memory number 0 of the RAM 31 in FIG.
The above input time data is stored in the time memory as the auto mode reset time, while "1"
Is input, the input time data is stored in the time memory of the memory number 1 as the auto shut-off time.

Therefore, when the above processes are respectively executed for both, the auto mode reset time and the auto shut off time designated by the operator are stored in the time memories of the memory numbers 0 and 1 of the RAM 31, respectively.

Now, it is assumed that Tm0 is set as the auto mode reset time and Tm1 is set as the auto shut-off time as a premise that the timer count process described later is executed.

FIG. 5 is a flowchart showing a timer counting process.

First, during the copying operation of the copying machine main body, the RAM 31
Are always set to 0, and when the copying operation is stopped, both timers start counting [steps (31), (32), and (33)].

Thereafter, the CPU 33 compares the count time tc1 of the timer 1 with the time data Tm0 of the time memory (memory number 0), and compares the count time tc2 of the timer 2 with the time data Tm1 of the time memory (memory number 1). Keep comparing [Steps (34) and (36)].

When tc1 ≧ Tm0, the copier load 35 is controlled to reset the auto mode by the mode reset processing routine stored in the ROM 30 [Step (34).
(35)] On the other hand, if tc2 ≧ Tm1, on the other hand, the relay 37 is controlled by the shut-off processing routine stored in the ROM 30, the switch 36 is turned off, and the power supply to the copying machine is cut off (step (36) ( 37)]. Even if the power is cut off,
Since the RAM 31 is a nonvolatile memory, the data in the memory is retained as it is for each time.

As described above, in the present embodiment, the case of one auto mode reset and one auto shut off has been described.
If a large number of time memories are provided and a timer corresponding to the number is provided, a large number of auto mode resets can be executed. Further, it is also possible to use a single counter instead of configuring the timer as the RAM 31, and compare the output of the counter with the time data set in each time memory.

Effect The present invention allows the operator to set the reset time of a plurality of operation modes by input means, instead of selecting from a fixed mode reset time as in the prior art. Each reset time of the mode can be set arbitrarily,
It is possible to flexibly manage the reset time according to the use mode of the copying machine.
