Abstract

PURPOSE:To decide the number of times of copying operation and to display the decided result by forming a repeating mode selecting means for commanding the repeated copying operation of the number of sheets set up by a key entry means and a display means for deciding the number of times of copying operation and displaying the decided result. CONSTITUTION:A copy number display means 5 is provided with a driver 5a for inputting an ON/OFF copy number display signal S3a outputted from an output port O1a of a control part 4, a driver 5b for inputting a continuous ON signal S3b outputted from an output port O1b, an ON/OFF continuous switching means 5c for switching the output signals of both the drivers 5a, 5b, and a display unit 5d. When operation is executed in a mode for repeating a displayed set value for the number of copies twice, the display unit 5d subtracts the displayed number by '1' every end of one copy while being turned on and off in the 1st time, and in the 2nd time, subtracts '1' every end of one copy by continuous copying without being turned on and off. Consequently, the current number of uncopied sheets can be read out from the display unit 5d without fail and the number of times of copying operation can be extremely easily decided.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a copying apparatus having a continuous copy number setting function and a display function.

[Conventional technology]

In conventional copying machines of this type, in order to set the number of copies to be made, there are numeric keys (usually numeric keys) for inputting the number of copies, and display of the input number of copies.
During the copying operation, the operation section is equipped with a display that dynamically displays the number of remaining copies while decrementing the display by 1 each time one copy is completed. Then, if you specify the number of copies by pressing the number key and then press the copy start key, the copying machine will automatically repeat the copying operation for the specified number of copies.
It is configured so that multiple copies can be efficiently obtained.

In this case, the maximum number of sheets that can be set for continuous copying is, for example, nine if the number of displayed digits on the display is one digit, and 99 if the number of displayed digits is two digits.

If you need more copies than that, for example, if you need to make continuous copies twice the maximum settable number above, you can set the i! I! The number of copies to be copied will be repeated twice and the copy operation will be performed.

[Problem that the invention seeks to solve]

However, conventional copying devices have many disadvantages. The means for displaying the number of copies to be printed is configured to simply reduce the number displayed on the display by rlJ each time one copy is completed, and when the set number for the first copy reaches zero, the display for the second copy is displayed again. The number of sheets currently being copied was decreased by 1 in exactly the same way, so it was difficult to determine whether the number of copies currently being copied was :fr, the first copy or the second copy. The problem was that it couldn't be done.

The present invention eliminates the problems of the above-mentioned conventional example,
It is an object of the present invention to provide a copying apparatus that can determine and display the number of copying operations when consecutively copying a predetermined number of copies aQ using key input means for setting the number of copies. It is said that

[Means for solving problems]

To achieve the above object, the present invention provides a copying apparatus that includes a key input means that can set a plurality of copies, and a display that displays the number of copies set by the key input means and the completed number of copies. The present invention is characterized by comprising: green return mode selection means for instructing to repeat the copying of the number of sheets set by the key input means a plurality of times; and display means for determining and displaying the number of copying operations. It is a copying device.

[Effect]

The repeat mode selection means according to the present invention is operated when continuous copying exceeds the maximum number of display digits on the display.

In that case, first enter the required number of sheets (11n) using the numerical key input means.
However, if you set a number (n is the number of copy repetitions) and then set the repeat mode, the copying operation of the copying device will automatically repeat the same number of copies again after the number of copies set by the number key input is completed. . The display means distinguishes and displays the number of copying operations.

〔Example〕

An embodiment of the present invention will be described below with reference to one drawing.

FIG. 1 is a block diagram of the configuration of an embodiment of the present invention. In FIG. 1, 1 is a numerical key input means that outputs a signal S1 to enable setting of a plurality of copies, and 2 is a numerical key input means for outputting a signal S1. It is a repetition mode selection means that outputs a repetition command signal S2 instructing a multiple number of copies of the number set by means 1, and these constitute a copy number setting means 3. Reference numeral 4 denotes a control unit composed of, for example, a microcomputer, which stores a CPU (central processing unit 22) equipped with a computing unit, and a copy sequence program for copying operations, including a key input processing program for setting the number of copies, which will be described later. It is equipped with a memory (ROM), a data memory (RAM), an accumulator (ACC), and an input/output port for various signals.

A numeric key input signal S1 is input to the input capo) It,
A repeat command signal S2 is input to the input capo Iz.

On the other hand, a blinking copy number display signal S3a is output from the output port OHa, and a copy number display signal S3b for continuous lighting is output from the output port 01b. Various control signals S4 necessary for copying operations etc. are output from the output port 02. 5 is a display means for displaying the number of copies inputted by the numeric key input means 1, and is output from the output port O+a of the M control section 4. A driver 5a to which a blinking copy number display signal S3a is input, a driver 5b to which a continuous lighting signal S3b from output port O+b is input, and a blinking/continuous switching means for switching the output signals of both drivers 5a and 5b. 5C and a display 5d. Reference numeral 6 denotes a known copying means that performs a series of copying operations according to a copying program, and which drives various AC loads (for example, a main motor Each motor including heater.

A fan, a document illumination lamp, etc.) and a DC load (for example, a counter, a paper feed solenoid, a surface potential control means, etc.) 6b are provided.

FIG. 2 is a plan view of the operating section of one embodiment of the present invention. In the figure, the numeric keys 0 to 9 (numeric keypad) represent the aforementioned numeric key input means 1, and the asterisk "tree" key (asterisk) represents the return mode selection means 2. In addition,"
C" is a clear key. The input of each of these keys is detected by dynamic scanning.

The display i5d is composed of a 7-segment light emitting diode, liquid crystal, etc. that dynamically displays the set number of copies and the number of completed copies. 7 is a stop key for stopping the copying operation, and 8 is a start key for starting the copying operation.

Next, the operation will be explained based on the key input processing routine flow of the microprocessor 4, which is a control unit for realizing the present invention, shown in FIG.

First, the areas ``rBUFFERJ'' and ``one flag'' are secured in the data memory (RAM).

In step P1, a key is input in the copy number setting means 3, and in step P2, it is determined whether the input key is a numeric key. When a number key is input, the process moves to step P3, and the input number is stored in the RAM.
r BUFFERJ area and return to step P1. If no numeric key has been input, the process proceeds to step P4, where it is determined whether or not the ``one key'' which is the eel return mode selection means 2 has been input, and when the ``real key'' has been input, the ``real flag'' is set. Returns to PI as on state.

If the "real key" is not entered, proceed to step P6.
It is determined whether the clear key rCJ has been input. And when clear key "C" is input, r BUFFE
1 is stored in RJ, the "main flag" is turned off, and the process returns to step P1. This is a function to cancel the mode in which the set number of sheets is repeated twice by inputting the clear key "C". In step P8, it is determined whether the copy start key 8 has been input.

When copy start key 8 is input, step P
Go to step 9 and check the "main flag", and if the "main flag" is on, proceed to step PIO and read the r of RAM.
At the same time as copying the set number of sheets stored in the BUFFERJ area twice.

In addition, output to determine whether the set number of copies is being made for the first or second time (
The first time is a blinking display by signal S3a, the second time is by signal S3
(continuous display using b).

On the other hand, when the "main flag" is in the off state, the process moves to step p++ and enters a sequence in which the set number of sheets stored in the rBUFFERJ area is copied only once.

According to the above key input processing routine, when operating in a mode that repeats the display number setting value twice, the display 5d blinks the first time and decreases by 1 each time one copy is completed. , the second time it displays continuously without blinking,
It is decremented by l each time one copy is completed.

As a result, the current number of unfinished copies can be read without fail from the display 5d.

In addition, in the repeat copy mode, instead of switching the display 5d as a display means between "blinking" and "continuously lit" for discrimination, a discrimination lamp is provided on the operation unit as another display means, and the first It is also effective to continuously light or blink the discrimination lamp during the first copy operation, and turn off the lamp during the second copy operation.

Furthermore, it is also effective to provide a buzzer for notifying repeat mode as another display means, and to sound the buzzer when the first copying operation is completed to distinguish between the first copying operation and the second copying operation.

〔Effect of the invention〕

As explained above, by providing display means such as a segment display that can be switched between blinking and continuous lighting, a discrimination lamp, and a buzzer, in the L & return copy mode,
This makes it extremely easy to determine the number of copy operations, which is effective in knowing the current number of copies remaining without any doubt.
