Abstract

PURPOSE:To generate an operation array of many equipments systematically at every interval of a master pulse, by generating the master pulse from the rotating shaft of a main motor and performing all control operations on the basis of the pulse. CONSTITUTION:A device A includes a main motor M and command buttons b1- b3 and the main motor M generates the master pulse by a means DP. An output array memory OTL generates output patterns of the equipments a1-a4 in such a way that the bit is 0 when the internal counter of an equipment memory DVM is counted down to zero by the master pulse or 1 in other cases. Thus, the all control operations are carried out on the basis of the master pulse.

Description

[Detailed description of the invention] The present invention relates to an image forming apparatus a.

FIG. 1 is a block diagram of the present invention.
A device i'f having a main motor A and command buttons b1 to b3. DPI-J main motor M generates a mask pulse, and JJ1'IF is an operation initial stage f'1. , MoM(-j
[) Mark count table memo IJ and DVM that memorize the start of operation and duration of operation of the device 3)
The timer memo IJ and OTL, which have the remaining time until the time is reached and record it as a count, are pit 0 when the count in the device memory DVM is calculated by the mask pulse and becomes 0, for example, as a count. Output array memory that forms the output pattern of the device as bit 1 when other than 0T
S) An output control string memory that stores combinations of devices that can be activated within a certain period of time in a pattern arrangement of 1.0. In comparison with
This memory is used to update the TS after a certain period of time.For example, as described below, it stores the array of process modes, s'rax, and the combination of A devices that are started for each process. Including OTSM.

PM is a program memory that stores these memories and processing procedures of the processing means OPU♂, and OPU memory M
This is a processing means for driving and controlling the DVIF by processing the data and the signal from the DT sensor F.

Here, H is the main motor and T is the driving force 6 which is the basis of control operation.
At 13 minutes, the 43'r-tri will be the basis for determining the state of the entire system. To give a specific example, the rotation of the photosensitive drum drive motor in a copying machine is the reference for the duplication process, and the number of rotations after startup uniquely determines the state of the copying process. There are hundreds of things that can be done.

The present invention aims to generate a mask pulse, which is the fundamental IJ command of control, from the rotating shaft of the main motor that has such qualifications, and to make all control operations follow the same sequence based on this. be.

Device memo IJ D V M f contains data indicating the status of each operating section, and indicates the operating section that should be operated continuously.
ll, the time in the building from the first room to the stop is distributed in the form of a count. Possession count ○ indicates when it should not be output.

The mark count MCI after DVM A is entered in the form of the MO's count until the next DVM revision. Data for the DVM is supplied from a separately stored i-fuculant memory MUM. Also, MOMl is a memory that specifies a sequence, and a mark callan representing the operation start point of one or several operating units) I) M
O and a numerical value indicating its expected duration DUR are included as count class. IJMO stores only the increment from the previous mark count (Figure 6 1) V M
and MoM JKt).

The main part of the program consists of block 1B (see FIG. 8).

That is, using the result of the mask pulse continuation d1, create the state code of the target system υ, and output according to the state code. 00TL, which creates the operating section to be suppressed in the form of an output suppression train OT8, is formed as follows: J) V M , M in Fig. 6
Referring to OM 11, the previous J° system is the regular &I
When starting work, 0 for MO, MUM for MO work.
The first @ address of is entered (initial condition).

The steps are 1. First, the MO is read, and if it is 0, it is returned to v00, and the DtJR count specified in the MOM of that address is stored in the DVM storage space specified in the DVADR item. jft and set the DMO count to Va
and enter the next address in MO. MO is 0
When this happens, this procedure is repeated, and the operation of the operating unit DV F at count 0 is completed by setting the count to the DVM.

Here, read the master pulse by /lr, and each time you stare at 1 (fJ), you will equally subtract one count from the part of the DVM that is not O. This subtraction also applies to MO, and if it is not O. 1, only the DVM count that is not 0 is assigned a 1 on the output column OTL. This O

Finally, only those "operations that are inhibited by s and should not be output by C and should be output by OTL" are output.

14 weeks to return to the starting address of MUM.

Also, if we add a signal indicating the time point at which the output control train OT8 is programmed to the count value of the mask pulse as J+a, we get +11.
The TO is modified according to a certain procedure, which is converted to 01"S by conventional logic circuit means (or the BTU is changed to 01"S by means of conventional logic circuits (or the BTU is set to tkL1!!ifiy"
It is also possible to store the numbers in a 1000 and take them out one by one as you advance through the addresses.

This method is used in the following examples).

An example in which the above structure and operation is applied to a color electronic illumination camera will be explained.

The primary color image is created by the imager and transferred onto the transfer drum synchronously onto the copy paper that has arrived.The color separated image is IL)it( Since it is developed in the order of magenta) and 0 (cyan), it is transferred to the coffee paper on the transfer drum three times, and finally peeled off with a minute 1%a nail and sent to the fixing device.

Some peripheral controls add +1 to this basic override + rotation υ. The main one is 11) 111. Power on, power off, copy mode (color or

Paper feed amount) 1. 4) filter rotation, 5) pre-exposure, main IKI brightness, full Fd light, 6) fixing heater output, 7) development 1rJj cut, 8) conveyance check (paper jam detection), etc.

These operations are controlled by a signal based on the rotational position lit of the transfer drum. The time chart is shown in FIG.

For example, the solenoid M (131'', which drives the separation claw)
In the case of three-color copying, it is activated during the first rotation of the transfer drum after the completion of the cyan process and lasts for one rotation. In the case of a single color, for example, in the single color yellow mode, NJ1 starts in the middle of the first rotation immediately after finishing the process for that color, and operates only for 1° rotation (Jy+). In addition, the developing solenoid OLI is activated every time the 1st drum is operated many times in succession with 711 colors (dotted red stamp line). Therefore, while the development solenoid C moves during the backward rotation of the three colors, the development solenoid corresponding to that color remains in operation before the backward rotation of the JIT color. In other words, even with the same backward rotation 101, the equipment that can be used differs depending on the color mode process (movement) of the handshake and the past work notification history (se ■υgaeshi or white). .

For the above-mentioned reasons, the operation of the copying machine operating equipment is determined not only by the position of the transfer drum but also by the state of the copying machine in the color mode and the process mode. The process flow diagram in FIG. 4 shows the transition of the state.

In other words, in the case of three colors, after the process mode Vllll r 12 of two forward rotations, the yellow yo and the cyan aO are transferred to the machining machine M, and when the time passes with -'t-re, @tl is turned backward as it is F' Set the process mode of ltl, pr+2, standby, or take 2 or more copies, then each yellow, magenta, and cyan process Y, which is different from the previous one.
1, Ml, and 01 are repeated in the spring/1, and upon completion of copying, enter backward rotation FR1 and FRg.

In the case of single color, there is no tjij rotation, and there are YQ, MO,
O (J, 2 or more cards) When taking a second cohi, for example, after turning M2 and turning back, turn FR1,
Enter FRg.

In order to execute these processes and complete the process, we set up the memory shown in Figure 0, and the memory values υ and j) t
#) The control (l'Ii1) is performed by the well-known micro OPU according to the procedure shown in the flowchart of FIG.

One rotation of the drum is performed by one of the process shades mentioned above. Since the equipment to be activated or deactivated during one rotation is determined for each process mode, data for output management is stored in the #U order of the memory OTSMK process mode transition. is set in advance as 4×8 bits 01. Also, according to the sequence table 1 corresponding to the MOM described above, as shown in FIG.
It contains the data J) υR of the holding capacity, and is stored in advance in the memory field 7/i.

The position of the transfer drum is detected by receiving pulses from a photoelectric pulse generator mounted on the shaft of the drive morph 22. One rotation of the rolling J-drum corresponds to [1] 0200 rotations of the mork shaft.

During one rotation of the transfer drum, each motor starts or stops sequentially, and when a misfire ψj is 1, the time when these start is noted as the count number of one morkshaft and is taken as a mark count. For example, when the fl (movement motor) starts the transfer drum, the devices MO4, I, A4, MO3, OL
