Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a copy image forming apparatus having a plurality of types of copy process operation modes, and more particularly, to mode setting immediately after power-on.

[Prior Art] In a conventional copying machine, the state of the machine is set to an initial state by turning on a power switch (power connection). That is, the set number of copies is set to 1, the copy magnification is set to 100%,
The automatic paper selection mode and the automatic density mode are set to the normal mode, and the special modes such as sorting / stacking and double-sided are set to cancel.

In such a copying machine, as shown in Fig. 7a, the power supply to the machine was connected / disconnected only by the power switch (power SW), so that the occurrence of jam, paper end, toner end, etc. caused the copy to occur. When the front cover or the like of the copying machine was opened halfway, the power supplied to the machine was alive, and the power supply of the machine was not shut off due to supply of the supply. When the front cover of the machine is opened, the AC power supply is connected by the relay (RA) shown in Fig. 7a.
The power supply of DC24V system was cut off, but the power supply of DC5V system used in the control system such as CPU was connected.

However, in such a configuration, the power supply is cut off by a relay or the like, which complicates the hardware configuration and leads to an increase in cost. In addition, even if you open the front cover etc., the power supply of DC5V system is alive, so you have to consider the safety for users.

Therefore, as shown in FIG. 7b, a cover safety switch (door switch) is further interposed between the power supply and the DC power supply. There is known an apparatus which solves the above-mentioned problem when a front cover or the like is opened by opening a switch to cut off power supply to the machine.

[Problems to be solved by the invention]

However, when the front cover and the like are opened and closed in the copying machine having the configuration shown in FIG. 7b, the power supply circuit of the machine is turned on / off accordingly, and the state of the machine is initialized (initial mode setting in response to the power on). ) Will be.

As a result, there is a problem that the user has to input and set a new desired mode via the operation board, which makes the operation cumbersome.

SUMMARY OF THE INVENTION An object of the present invention is to facilitate setting of a copying operation mode of a copying machine, particularly, setting of a required mode after turning on a power supply again after a power supply circuit is turned off during copying of a required number of sheets.

The optical scanning system 30 includes an exposure lamp 31, a first mirror 32, a second mirror 33, a third mirror 34, a lens 35, a fourth mirror 36, and a slit.
It is composed of 37 mag.

When scanning the original, the exposure lamp 31 and the first
The first carriage on which the mirror 32 is mounted and the second carriage on which the second mirror 33 and the third mirror 34 are mounted are mechanically scanned and driven at a relative speed ratio of 2: 1 to keep the optical path length constant. . The moving direction of the first and second carriages, that is, the sub-scanning direction is the horizontal direction in FIG. 2, and the sub-scanning start position is the left end.

The lens 35 is a zoom lens, and can be driven by a motor to change the copy magnification. The light emitted from the exposure lamp 31 is reflected on the surface of the original, and passes through the first mirror 32, the second mirror 33, the third mirror 34, the lens 35, the fourth mirror 36, and the slit 37 onto the photosensitive drum 2. It is imaged.

The electric charge in a portion not used for making a copy is erased. On the charged surface of the photosensitive drum 2,
When the reflected light from the document is irradiated, the potential of that portion changes (exposure and static elimination) according to the intensity of the irradiated light.

Since the optical scanning system 30 sequentially scans the document surface in synchronization with the peripheral surface speed of the photosensitive drum 2, the potential distribution corresponding to the density (light reflectance) distribution of the document image is formed on the surface of the photosensitive drum 2. ,
That is, an electrostatic latent image is formed. When the portion on which the electrostatic latent image is formed passes near the developing cartridge 5, the toner in the developing cartridge 5 is electrostatically attracted to the surface of the photoconductor 2 in accordance with the potential distribution, and the toner corresponding to the electrostatic latent image is formed. Visual image is photosensitive drum 2
Formed on (development).

On the other hand, in synchronization with the progress of the copy process, a recording sheet is supplied from any one of the five paper feeding systems. The recording sheet is fed via a registration roller 27 so as to overlap the surface of the photosensitive drum 2 at a predetermined timing, and is transferred by the transfer charger 7 to the photosensitive drum 2.
The upper visible image (toner image) is transferred, and the recording sheet onto which the visible image has been transferred is separated from the photosensitive drum 2 by the separation charger 8. The separated recording sheet is transported to the fixing device 12 by the transport belt 11. After passing through the fixing unit 12, the toner image on the recording sheet is fixed on the recording sheet by heat in the fixing unit 12. The fixed recording sheet is discharged to the sorter 70 or the automatic duplex unit 80 through a predetermined discharge path.

Next, FIGS. 1a and 1b show the main control board 20 of FIG.
2 shows a control function of the microprocessor 210 on 0. First, the contents of various symbols shown in FIG. 1b will be briefly described.

Ccopy: Copy number counter Counts the number of completed copy processes. It is cleared to 0 when the copy process for the set number of times is completed.

Nset: Number of copies set value The number of copies per document is set. This number is designated by the numeric keypad KI0.

NK: Numeric keypad input register Holds the decimal value input from the numeric keypad KI0.

Referring to FIG. 1a, the operation of the microprocessor 210 will be described. When the power is turned on, CPU initialization processing is first performed (step SA1: hereinafter, in parentheses, the word "step" is omitted, and only the number is omitted. Write).

In this process, the state of the main control board 200 itself is initialized. That is, the contents of the read / write memory 230 are cleared, various mode settings are initialized, and the output port is reset.

Next, the evacuation area flag FL for controlling the evacuation area is checked (SA2), and if the evacuation area flag FL is 1, it is set to 0 (SA3), and the evacuation elif flag F is set.
If L is 0, it is set to 1 (SA4). The evacuation area is the fifth
As shown in the figure, this is an area for always storing the state of the machine (setting mode, copy conditions, etc.) in the nonvolatile memory 290, and stores the current state and the state one time before the power is turned on. ing.

Next, the machine is initialized (SA5). In this process, the states (operation modes) of various boards and various devices connected to the main control board 200 are initialized to set the copying machine to the initial state.

Further, the mode setting of the timer 270 and the setting of the count value are also performed.

Further, as shown in FIG. 3, the main control board 200, the operation board 310, the optical system control board 320, the AC system control board 325
The process of starting serial communication between the three boards and the process of transmitting initial data are also performed in step SA5.
Done in For example, in the serial TxD (main optical) of FIG. 3, lens correction data is transmitted from the main control board 200 to the optical system control board 320 when the power is turned on.

Next, a standby mode process is performed (SA6). At this time, since the copying operation has not been performed, the machine has stopped and is in a standby state. In the standby state, first, the state of the signal applied to the various input boats is read, and the result is stored in the memory 230. Next, the data group for output control stored in the memory 230 in advance is output to the output boat associated with each data, and the device connected to the output boat is controlled.

Further, the state of various input boats stored in the nonvolatile memory 290 read in advance is determined, and the presence or absence of an abnormality is checked. If there is an abnormality, predetermined abnormality processing is performed according to the content of the abnormality. For example, when it is detected that there is no paper or silicon oil for fixing toner, a paper end display, a toner end display, an oil end display, a message (guidance) display prompting replenishment, and the like are displayed on the operation board 310. In addition, if an error that requires repair by a serviceman such as burnout of the fuse for the fixing or burnout of the exposure lamp occurs, the details of the error and a message prompting the operator to call the serviceman are displayed in FIG. Or displayed on the operation board shown in. These display data are sent to the main control board 200 via serial communication.
To the operation board 310.

If there is no abnormality, the state of other input ports is determined and processing is performed. For example, input processing from the operation board 310 (FIG. 3) is performed (input data from the operation board 310 is also transmitted to the main control board 200 by serial communication). In this processing, the state of various mode selection switches (FIG. 4) provided in the operation board 310 is determined, and the subsequent processing is determined according to the result.

Next, it is determined whether or not a key input has been performed. If a key input has been performed, a process corresponding to the key input is performed. For example, in the normal operation mode, when there is an input from the numeric keypad KI0, the numerical value associated with the pressed key is stored in the copy number register.

In addition, if there is an input from the magnification adjustment keys K6a, K6b, etc., the variable magnification data is sent to the optical system control board 320.

Further, display data previously stored in the memories 230 and 290 is output to the operation board 310 at a predetermined timing by using serial communication, and the data is displayed on a display on the operation board 310. The data to be displayed is switched to a display state for each destination according to the state of the mode switch and displayed. For example, the setting value of the number of copies is displayed on the display D1 by the microprocessor 210 in the operation board, and the copy magnification is displayed on the display D4.

Next, it is determined whether or not a mode return signal has been input (SA7). When the mode return signal is input,
Information is taken out from the save area which stores the mode before the power is turned off when the save area flag FL is 1 or 0, and the mode is restored. Evacuation area flag FL is 1
If so, the mode is set with the data in the area 2 shown in FIG. 5 (SA9). If the save area flag FL is 0, the mode is set with the data in the area 1 shown in FIG. (SA10). FIG. 5 shows a process in which the state of the machine is always stored in the non-volatile memory 290.
Is determined to be stored in either the save area 1 of the nonvolatile memory 290 or the save area 2 depending on whether the value is 0 or 1.

Although the processing shown in FIG. 5 is not shown in the schematic machine operation flow charts of FIGS. 1a and 1b, it is a processing that is always performed, and the latest machine state and mode are stored. I have.

FIG. 6 shows an example of the memory mapping of the nonvolatile memory 290.

Returning again to FIG. 1a. The mode return signal is generated by pressing the mode return key KT in FIG. In the case of a machine without a mode return key, a mode return signal may be generated by simultaneously pressing two or more keys (for example, when the clear key KC and the # key K # are pressed simultaneously). etc).

If the copy is not possible in step SA11, or if the print start key KS is not turned on in step SA12, the standby mode processing (SA6), the determination of the mode return signal (SA7), and the mode setting (SA8 to SA10) are repeated. Execute. Copying is not permitted, for example, when the fixing temperature is out of the predetermined range, when the supply state of the paper end, the toner end, the oil end, etc. is supplied, or when any abnormality is detected.

Referring to FIG. 1b. When the pudding key KS is pressed in a copy enabled state, a pre-copy mode process is performed (SA13). In this process, as the process immediately before starting the copying process,
The main motor drive starts, the photoconductor drum 2 is cleaned before copying, and so on. The number of copies (NK) input in advance using the numeric keypad K10 is the copy number setting value register Ns
Stored in et.

At this time, the main control board 200 sends the optical system control board 3
Send the interrupt mask release data to 20 by serial communication. This is the main control board 200 during the copy operation.
This is because the communication of the timing relation between the optical system control board 320 and the optical system control board 320 is performed by using the interrupt signal, and whether the interrupt signal is enabled or disabled is performed by serial communication data. . That is, the interrupt signal is valid during the copy, and a timing signal required for the copy operation is exchanged, and the interrupt signal is not required during the standby period, so that the interrupt is masked.

When the pre-copy mode processing ends, the copy mode processing is executed (SA14). At this point, the copying process is actually performed. This process includes a copy process, a paper transport process, a toner supply process, an abnormality check process, and the like.

In the copy process, on / off control of each process element, machine operation element, paper feed element, and the like is performed at a predetermined timing synchronized with the output of the timing pulse generator that generates a pulse corresponding to the rotation amount of the main motor. When the scanner start signal is sent as an interrupt signal to the optical system control board 320 at a predetermined timing, the LE (lead edge) signal is interrupted from the optical system control board 320 to the main control board 200 when the exposure lamp comes to the leading edge position of the image. It returns as a signal. When the main control board 200 receives the LE signal, it changes the value of the timing pulse to a certain value (in this embodiment,
1928).

This pulse correction is performed to correct the position of the image on the photosensitive drum and the transfer paper fed from the paper feed port.

In other words, when the LE signal is received, the image of the leading end of the document is just formed on the photosensitive drum. Therefore, the transfer position where the LE position meets the leading end of the paper from the layout around the photosensitive drum in FIG. The distance to can be calculated. Then, since the distance between the registration roller and the transfer position of the sheet is constant, the registration start timing can be calculated from the LE timing.

In the present embodiment, if the LE signal is 1928 pulses and the distant start is 2000 pulses, the image is transferred exactly at the leading edge of the sheet.

If an error or a jam occurs during the copy mode process (SA14), the process shifts to the error / jam process (SA15).

If there is no abnormality or jam, the copy mode processing (SA14) is repeatedly executed until the one-cycle copy process is completed.
Ccopy is incremented (+1) (SA17), and the result is set to the copy number setting value and compared with the contents of the register Nset (SA
18). If Ccopy = Nset, the copy mode processing (S
Proceed to A14) to start the next copy operation.

When Ccopy = Nset, that is, when the copy mode processing (SA14) for the final copy is completed, the contents of the counter Ccopy are cleared (SA19), and the post-copy mode processing is executed (SA20). In this process, a paper discharging process to which the copy image is transferred, a post-copy cleaning process of the photosensitive drum 2 and the like are performed.

When the discharge is completed (SA21), the process returns to the standby mode process (SA6 in FIG. 1a), and the above process is repeated.

In the abnormality / jam processing in step SA22, all the driving loads of the machine are turned off to stop the operation, and the reason is displayed on the display unit of the operation unit. If a jam has occurred, the jam display and the location where the jam occurred are displayed, and if a machine error has occurred, the contents are displayed. The state information and the mode information including the abnormality / jam and the like are written in the area 1 shown in FIG. 6 if the save area flag FL is 1, and in the area 2 if the save area flag FL is 0.

In the machine according to the present invention, if an abnormality or a jam occurs, the abnormality or the jam cannot be cleared without turning off the power of the machine. Therefore, after performing the abnormality / jam processing (SA22), the state remains as it is. It is held.

Therefore, the power of the machine is turned off by opening the front cover or the like, the machine is turned on by closing the front cover or the like after the abnormality or jam is cleared, and when the operator presses the mode return key KT (FIG. 1a). Step SA
7) The information is taken out from the save area that stores the mode before the power is turned off, and the mode is restored.
Further, unless the operator presses the mode return key KT, the state of the machine is set to the initial state.

〔The invention's effect〕

As described above, according to the present invention, the previous mode is automatically set in the copying apparatus only by the operator inputting the return using the mode return instructing means (kt). It is very easy to reset the mode during the previous power-on after the power is turned on again.
