Abstract

PURPOSE:To reduce the cost by inhibiting input operation based upon a key input means after a process means starts forming an image. CONSTITUTION:An operator inputs the desired number of copies after electric power-on operation and then presses a copy start key to start copying cycles. Whether an end mode is set or not is judged on every copy cycle and when so, a return to the cycle of the setting of the desired number of copies and the entry of the copy start key is made and a stand-by mode is entered. Consequently, the number setting and the entry of the copy start key in copy cycles are inhibited and the copy cycles never start during the key entry. Consequently, a display device, etc., are simplified and the cost is reduced.

Description

[Detailed description of the invention]

The present invention relates to an image forming apparatus such as a copying machine. Conventionally, it is known to set the number of copies using a key and control the repetition of the copying operation accordingly. In this case, since the number display requires a plurality of digits, if other display devices are used, the cost increases and the copying operation may be inconvenient. The present invention is designed to eliminate the above drawbacks. Furthermore, by using this example, the tracing machine l! It is possible to program the TO' and recording sequences in chronological order, making it extremely easy to change the sequence. 'W Vc, according to this example, (b) road? kJ concentration becomes possible, and the gI (product number can be reduced by RFJ (C). It has the feature of being able to control the sequence of the equipment. (In this example, if Vc died and the device was driven, it would not be possible to fire it if the process leading up to the Vc of building that device has not been completed. Since the input IA (No. 5 does not work), there is a % symptom that #l does not operate. Furthermore, this example has a 7"'' program real drum home position 1u

In short, the four basic clocks are used to store the program 1. Specify the alignment location V, specify the address, and decipher the command code that is used to store that address. Execute the contents of the above instruction within 6 clock cycles. Then, again,
The programmed instructions following the above address are executed at 161-like time intervals.

sec. Of the two, *'C1, there is an internal oscillator that generates one pulse per 1 degree of rotation angle of the screen ram (anything is possible, including an astable multi-vibrator). The diameter of the slurry/11 drum is 110 mψ and Z, so the clock period tj of clock pulse 1 is about 8 m/sec, and similarly the clock NMld of clock pulse 2 is 2.66 m/sec. These clock pulses are obtained by optically detecting the rotary plate 5 fi F hole 6o, which rotates at a rate several times that of the PM drum.
It can occur at any time. When the status signal is at the 111 level, 1 is absent or N (i means 12, and 12 is the level), and 111 is the level of the status signal (111). The control circuit 1 in the figure is from a known r-) circuit in which a 4-bit signal is output with the read 1 control signal 2, and a known gate circuit in which a 4-bit signal is input with the write control signal 2. In addition, the control circuits Ml-t and M3-4 shown in Figs. The r-) circuit consists of a well-known r-) circuit in which a data code is taken in by the input tb11 Gohakugo 2 and the selection signal of the input device I.The following figure 7 shows the schematic flow of backward control using the program method. After turning on the power, a key entry cycle of setting the number of copies and starting a copy is executed, and if the machine is in a standstill state, the cycle is looped and a key entry waiting state is entered. When the orderer enters the desired number of copies and presses Start Copy W-, the depth of the copying cycle begins. When the machine is in the end mode, the copying cycle is looped. If it is in the mode, the copying operation is stopped, the process returns to the initial cycle of setting the desired number of copies and entering the copy start key, and waits. Setting the number of copies inside and entering the key to start copying are disabled.

This is done using the value key, the 6 multi" key for starting continuous copying, the °"shingle" key for starting copying one sheet, the °°stop' key for issuing a stop command, and the 6 clear" key for setting the number of copies of 81. The flow shown in Figure 8 will be explained in detail below.

When a further 55 pulses are counted, the 'f & primary Teiden device is turned off (step 18), and when a further 47 pulses are counted, the forward clutch and exposure lamp are turned off to complete the original scanning (step 20). Therefore, there is no need to provide an optical system detection switch on the moving path to stop scanning. Next, 20 pulses are applied and 10 pulses are counted.

The contents of pB are transferred to register AVC and Stella f8-21 determines whether the high order of the subtracted numeric code is 0 or not. Since register A is not 0, we move R08'146vr, press C, jump to OM27, check Stella7'8-7, and execute the steps up to now again. Therefore, the rising edge of the copy clock (it A M Vc stored t and by incrementing the number of candy by -1, eventually the current step) is repeated a constant number of times [5, te\j, Sen code V, the upper digits are counted up to O.

Execute the steps up until now until the lower digit becomes 0. Then, when register A becomes OrC, the copy clock starts at 8.
After completing the 4 steps, the operation of the subject advances to the next 9 steps, and the next step is to turn on the trace box to the charger. Furthermore, since the synchronization of the clock pulse for the CPU is 1 μsec, the actual value of one cycle of the counting step on the ↓ screen? i Y(p rlN k, 1, assuming that it takes about 30 steps, at most 10 clocks x l per step)
Since it is μSCC, it is 300μ at most. The synchronization of the multiple lock pulses is as described above)
Since it is 1 msec, there is no possibility that it will affect the # number. At the controller rr vc as above, the command code of OM, the data code is 4MM, and the control signal α is output. This is a functional explanation of the steps shown in FIG. 10, and other steps K1141 can be performed with a similar configuration.
