Abstract

PURPOSE:To change and adjust the paper feeding timing, etc., by installing a means which inputs timing information, means which stores the timing information, and means which displays the timing information. CONSTITUTION:The copying machine counts pulse signals from a pulse disk synchronized to the rotation of the photosensitive drum in accordance with timing data stored in the 1st storage device 6, and, when the pulse reaches a prescribed number, performs necessary operations, such as paper feeding, etc. When transfer paper of a special size is used in foreign countries, it is necessary to change the paper feeding timing, etc. In this case, the ten-key 1 is switched from the number of paper inputting mode to the timing information inputting mode by pressing the manual program key 2 and the timing data after the change are inputted as a pulse number and read by the 2nd storage device 7.

Description

[Detailed description of the invention] The present invention relates to programmable reproduction devices.

Copying devices are generally equipped with a switch or variable resistor for adjusting timing information, and by adjusting the timing information using this switch or variable resistor, the registration timing of paper feeding, the home position adjustment of the movable optical system, or the time of variable-magnification copying can be adjusted. It is configured to adjust the lens position.

However, since the timing information is adjusted using a switch or a variable resistor in this double η 2 +F't, the adjustment of the timing information is restricted by the number of switches, etc., and the range of use is narrowed.

It is an object of the present invention to improve the above-mentioned drawbacks and to provide a copying apparatus that can precisely adjust timing information and can be used in a wide range of applications.

The present invention will be described below by way of examples with reference to the drawings.

Multiple device N? For example, the type of paper is different between 1] books and the United States, and 1-1 books are B5. A4. It is called A5 etc., but in the US it is called Rator, Legal, Double Rator, etc.

Therefore, naturally, "f's "j', doll ('
+σ) It is necessary to change the timing between Japan and the United States; lH
Previously, programs were different depending on specifications - IA tree memory or boards were manufactured and used - C1. ．． In contrast, in the present invention, since the timing information is manually stored in the storage means, the timing information can be freely selected, and even if the specifications are different, the same program can be stored in the memory or the board. may be used, increasing the range of uses.

Also resist clutch or clutch, motor.

When the operating timing of various sensors, etc. fluctuates over time, in the present invention, if the program is programmed to monitor the causes of the variation, the operating timing as described in -1- can be corrected by changing the timing information according to the monitoring results. be able to.

Further, in the present invention, the range of timing change can be freely set. - As an example, a 100φ photoreceptor l/ram is used, and an encoder that interlocks with the photoreceptor drum is 1
If you use an encoder that generates 500 pulses per rotation, you can control the copying operation by counting the pulses from this encoder with a clock counter and comparing each pulse with each timing information to obtain (100φ×π)÷500. = 0.
The accuracy is 62B rim. It can also be used to discover the cause by changing the timing when making repairs. For example, when checking the bias of the transfer corona discharger, turn off the transfer corona discharger, change the timing from the usual timing when the clock counter reaches 159 to the timing when it reaches 150, and check the image change of 11. ":stomach.

FIG. 1 shows a control system in an example 1i1+i of the present invention. In the figure, 1 indicates the number of copies and the operation timing of the copying machine using the 1u/1 [zui] key, and manual programmer gear 2 requires manual input of gear 1 using the 10 keys. This key is used to determine whether the number of copies per copy is done manually or the change timing is input.

The step key 5 is a key that changes a command for displaying the contents of the timing to be changed in steps. The keyboard and display control circuit 4 has various keys +, 2. 1 from N
No. 11k: The circuit that reads and outputs the data to the multiple machine control circuit 1° and the display data output from the HV Tγ machine flt control circuit 1o are timed to display the set counter display 12 (or copy no counter display). The circuit that outputs to the device 15): Rinaro. The command display control circuit 5 is a circuit that converts data from the multiplex machine control circuit 1 (1) into a character code and displays it (dynamically) at the appropriate timing.The first storage device 5-6 is Preset timing data is stored.Second memory word consisting of read-only memory @7
is a random access memory that stores timing data input from the 10 keys.

It is backed up by a backup power supply 15, and the memory state does not change even if the AC power supply is turned off.

The control circuit 8 includes a circuit that controls storing data from the copying machine control circuit 10 in the second storage device 7 and reading data from the second storage device 7, and a circuit that detects when the AC power supply is turned off. It consists of a circuit for storing necessary data in the second storage device 7.

The program set key 11 is a key used to execute multiple operations at changed timing, and the determination circuit 14 determines whether the timing data in the second storage device Z is valid data for executing a copy operation, for example, other than 0. This is a circuit that determines whether the data is The copying machine control circuit 10 is constituted by a central processing unit, and pulses are inputted from an encoder 9 interlocked with the photoconductor tram.

Next, the operation of this embodiment will be explained.

When the power is turned on, the step counter and the step counter are set to the address of the command first displayed by the display control circuit 5. The copying machine control circuit (hereinafter referred to as E P IJ) 10 checks whether the step key 5 is pressed or not, and if the step key 5 is pressed, the copying machine control circuit (hereinafter referred to as E P IJ) The direct sum of nl and n2 is added so that nl and n2 become the address of the first storage device n6 that stores the next command and the address of the second storage device r17 that can store the change timing data (see Figure 2). (al 2-
(See 1.2-2). Next, the CPU+O checks whether the step counter ■ is set to the preset value, and if it is the set value, sets the contents of the step counter ■, ■ to the same content as on the power-on screen (
Figure 2 (a) 2-5.2-4.2-5 Reference 11/j)
. Next, apu+o causes the command 1/display control circuit 5 to display the command stored in I1g at the address specified by the step counters ■ and ■ in the storage devices 6 and 7 (see 2-6 in FIG. 2(a)). . This result step key 5
Each time the key is pressed, commands with preset and changeable timing are displayed one after another, and when the last command finishes displaying, the first command is displayed.

Regarding the display of commands and their change timing data, as shown in FIG. 18, however, commands with changed timing data may be displayed on the display sections 16 and 17 as shown in FIG. 2 tol.

Next, CPU+O checks whether the 10 key in keys 1 is pressed, and if the 10 key is pressed, checks whether the manual program key 2 is on. If this key 2 is on, the data from the 10 key is stored as data at the changed timing in the address of the storage device 7 specified by the stamp counter ■, and the data stored in this storage device 7 is stored.

When the print I key is pressed, the CPU 10 starts the copying operation, and counts pulses from the encoder 9 interlocked with the photosensitive drum using the I cock counter. Then, the clock counter is compared with the change timing data in the second storage device Z and each timing data in the first storage device 6 (excluding that corresponding to the change timing data), and each timing at which they match is determined. Turn each part of the copying machine on and off to perform copying operations. In this case, if the program set key 11 is turned on as shown in FIG.
