Abstract

PURPOSE:To eliminate the deviation of sequence control with simple constitution and to perform excellent image copying, etc., by bringing the stopping of an electrostatic charger and a photoreceptor under sequence control at specific timing when an original illumination light source stops. CONSTITUTION:A CPU reads a program out of an ROM on the basis of a clock counted value according to a key input for image formation from an input device, detection signals from various state detectors, etc., and an output device outputs a sequence control signal conforming to an elapsed time. Then, the operation stopping of a charging means which charges the photoreceptor in a necessary period before and after the original illumination light source stops turning on and the rotation stopping of the photoreceptor are controlled. Therefore, the sequence control is carried out through the simple constitution without any deviation and image formation in improper state is prevented to perform the excellent image copying.

Description

[Detailed description of the invention]

The present invention relates to a method of controlling a recording device, etc. during copying. Conventional copying machines have been capable of starting image formation in response to a start command only when image forming conditions are appropriate. Therefore, even if an inappropriate state occurs immediately after the start command, image formation may be started without being able to cope with the situation, resulting in unnecessary copying. The present invention eliminates the above drawbacks. Furthermore, by using this example, it is possible to program the sequence of the recording evening in chronological order by using the

It has two internal oscillators (this can be an astable multi-vibrator or anything else) that generate one pulse per degree of rotation angle. Since the diameter of the screen drum is 110 mψ, the clock period of clock pulse 1 is approximately 8 m/sec l11-, and similarly the clock period of rC clock pulse 2 is approximately 266 m/sec.
These clock pulses t-r can be generated by optically detecting the holes 6 ( ) in the r121 rolling plate 56 that rotates at several times the speed of the insulating drum.

The card circuit consists of a known card circuit which can take in a putter code using inputs i++, 1, 2, and a selection signal from the input device (2). Next, in Figure 7 of the VC group, we will explain how to control the copying by the program force type. After turning on the power, first, the number of copies is set and the first key entry cycle is pressed.If the machine is in a standstill state in which nothing is done, the cycle is looped and the key e-tree wait state VC is entered.

Judgment (1, refers to when copying is completed, when a stop command is received, when there is no more paper, when there is no more paper, etc.) (1, indicating the end mode). For example, the copy cycle is looped. It is in the end mode, stops the copy operation, returns to the initial cycle of setting the desired number of copies and entering the copy start key, and waits. As described above, the copy operation is processed sequentially, so setting the number of copies during the copy cycle and bontry of the key to start copying are prohibited, and the H' discard cycle does not start during key entry (key entry cycle).

Is it shown in the flow diagram in Figure 9? It also includes an IC card that copies the collar for making the steps. First, use S'l''EPt to check whether there is paper and developer, and whether the fixing heater temperature is set.
If the above condition is OK, proceed to S'l''EP2 and move the drum motor (Vl') rotating at the first speed. I will explain this S'l'l bow P1 and 2 later. ?A [, S'l'l!; fi

Then, at 8'l'EP 6, the home position of the screen drum, which is mechanically VC-coupled to the drum motor and is already rotating synchronously, is EMu. Once at the Baum position, the rotating scree/drum waits until it reaches its home position.Details are given below (Fig. 11).
. 1iIII home is also '110? If VC came,
Since the QIJK optical system is waiting at its home position, the copy creation cycle begins after 5TEP7. Turn it on.The drum motor is already rotating (

If you make 10 copies using one latent image formed on the screen/r ram, then for a total of 55 copies, you will have to bend the latent image -16 times.
The number of repetitions must be stored in a part of the memory in advance by 8 pins. Therefore, 8'l'h enters the copy cycle.
:P At 7, store this (10 in this case) in the 4 vertical areas of the RAM as described above. Next, HTEP8 is entered and the number of clock pulses generated per 1'M rotation of the screen drum rotating at the first speed is calculated, and when this reaches 60 (i.e., the screen drum rotates 6♂ from its home position and 76 o'clock ) S'l'

If there is a mistake in Vi counting, only the clock pulse will depend on the VC (and if you control the sequence, it will be 5TEP.) Since the mistakes that occurred during one revolution of the screen drum up to 4 will be accumulated, 5TEP will be counted. 14 argument reset": This can be prevented. Similarly, S'l'EP 3s, 8'J"EP 57
, 5TEP 61 are also provided for the same reason. Since Si'EP 15 and later are based on the same idea as the above, I will omit the details. In other words, with this device): i, the sequence from the cost point to the changing voice is stored in memory in advance as the rotation angle of the scree/drum (i.e., the number of pulses), and when the number of pulses is reached, It turns the control device on/off. In other words, when 48 pulses are counted from the drum home position, #t11 is turned off, step 16).
When a further 55 pulses are counted, the rear primary charger is turned off (Step 18), and when a further 47 pulses are counted, the forward clutch and the rear pump are turned off (Step 20). Therefore, there is no need to provide an optical system detection switch on the moving path for terminating scanning. Next, do 20 pulses and do 10 pulse stitches and it will be 5TEP.
At 24, the production of the blank body on the screen drum is completed, and the transfer cycle to the insulated drum is immediately started, so the drum motor is switched from the 1st speed to the 2nd speed. Thereafter, there is a clock pulse 2 (described above) which occurs once per 10 rotation angle changes of the screen drum rotating at the second speed. Thereafter, similar control is performed to turn on/off the paper feed roller (step 30), l+! ! When VC39 pulses are counted, the forward clutch of the optical system is turned on and the optical system f~ is moved. Therefore, the delay until the start of forward movement after k is delayed by 4 or [7], so there is less shock when switching movement.

S'l'EP60 turns off the i1' developer, and 5TEP66 turns on the next screen.
If the home position of the drum is established and the end motor is not reached at this step, the process returns to S'I'EP 40 and repeats all the copies from the primary latent image. At S'l'EP 68, it is determined whether the end mode has reached the number of repetitions, or because the 5TOP command or the number of copies has matched the set number of copies, and the self-i

Turn off the motor (■2) to completely complete the screen drum cycle and return to the first key press/tree cycle, again when the operator's finger CP2 is at 330 (i.e. the screen drum is at its home position). By terminating the copying cycle at 3♂manuals), the drum stops slightly past the Baum position by 1 IPJ. Therefore, the operator then issues a copy command and at 8 TEP 5, the screen is twisted about one full revolution to reach the home position of the screen drum, thereby eliminating the extra time required for the first copy.

It is like the code rf'i which sets the human output device and memory itself which are necessary in the following procedure to perform copy control by making full use of command codes more than 7.X is the code. This means that the numbers are not limited to P. Table 4 In other words, the top four of the 12 address code bus lines are the lines for selecting the memory depth, and each memory and input/output device w has this solution. The other eight lines are lines for specifying the partial address of the memory, and each memory has a circuit known in itself for specifying the partial address of the memory. Each input/output unit in the input/output device has data 4b in this example.
Since it corresponds to each digit of it, no special designation circuit is required. Next, representative steps in the copying cycle shown in FIG. 9 will be specifically explained. Do not skip, step l and step 27!5
The f6 instruction flow in Figure 1410 and the code are cut into pieces. At 1- in the instruction flow, after step 0 of the key entry mentioned above, step 1-! Now, set address (1) (1110) of input device to register PB3,
In the next step 1-2, the contents of the input device 1ffi(1) specified by the register PB3 are transferred to the register A (

Stella 7'l-3 determines whether the contents of register A are 0 or not, and if 2 is negative, sets the address (0110) of input device (1) to PH1 again, transfers the contents, and determines Repeat 0 to 7. When the contents of register A are (), that is, the paper, toner, etc. of the human-powered device ([) are complete, the item is transferred to gauze 7"2.

In step 2-3, the contents of this register A are transferred E7 to the output device rMm designated by the register PB3, and the drum motor Vl of lθ4 corresponding to 0001 of the output device (1) is driven. Follow these steps! This will be explained in detail with an example of the circuit shown in FIG. 3 v'1. The execution procedure of the software 7'l and the software 2 is recorded in advance from addresses 1 to 8 of the ROM based on the above-mentioned storage. 5TEP) 4081 Flealand kLOM code 1-1 0(100000(100000100011

The surface of the tram is uniformly pre-charged (for example, positively charged) by a primary charger as the tram rotates.
Next, as the document table or the optical system moves, the optical image is scanned and projected, and at the same time, a recharger is used to charge the AC or tii7
The charge is removed by a direct current having a polarity opposite to that of the charge, and an electrostatic latent image is formed according to the brightness of the optical image. Further, the latent image is entirely exposed to light to form a high-contrast electrostatic latent image, which is then made visible by a developer mainly containing toner in a developing device. Thereafter, the corona H of the same polarity as the toner (for example, micro-nano if the pre-charge is positive) makes it easier to transfer the visual image, and it is transferred to the R passing paper and conveyed.
