Next, the document image erasing means will be explained.

In FIGS. 16 and 17, a guide shaft 130 is provided in the first carriage 411 along the lamp 4 in the part where the light of the lamp 4 is blocked, and this guide shaft 130 has a guide shaft 130 that is used to mark the erasing range of the document. Spot light source 1 as a means of giving instructions
31 is movably provided. This spot light source 1
As shown in FIG. 17, reference numeral 31 includes a light emitting element 132, such as a light emitting diode or a lamp, and a lens 133, which are provided opposite to the document table 2.
The light generated by the lens 32 is irradiated onto the document table 2 by a lens 133 as a spot light having a diameter d. This spot light has a brightness that allows it to pass through the document G set on the document table 2, which is, for example, as thick as a postcard. Further, the spot light source 131 is connected to the guide shaft 130.
Timing belt (toothed belt) arranged along
134. This timing belt 134
Pulley 136 provided on the rotating shaft of pulse motor 135
A hook is passed between the driven pulley 137 and the driven pulley 137. Therefore, by rotating the pulse motor 135, the spot light source 131 is moved in a direction perpendicular to the scanning direction of the first carriage 411. Further, a position sensor 138 consisting of a microswitch for detecting the initial position of the spot light source 131 is provided in the first carriage 411 located at the end of the guide shaft 130 on the pulse motor 135 side. For example, when the spot light source 131 is moved, the spot light source 131 first comes into contact with the position sensor 138 and its initial position is detected.

Next, a method for specifying the erasing range of the document using the spot light source 131 will be described with reference to FIGS. 18 to 20. This spotlight [131] is moved by operating the operation keys 3s to 3v described above in a state in which the main processor group 71, which will be described later, is in the document erasure range designation mode.

That is, when the operation keys 3t and 3v are pressed, the motor 33 is driven, and the first carriage 411 and the spot light source 1 are driven.
31 is moved in the scanning direction (arrow y direction shown in FIG. 18). Also, when the operation key 35.3u is pressed, the motor 13
5 is driven, and the spot light source 131 is moved in a direction perpendicular to the scanning direction (direction of arrow X shown in FIG. 18). The operator operates the operation keys +3S to 3v while visually observing the spot light transmitted through the document G, and for example, as shown in FIG. 19(a).
With the spotlight moved to point S1 on the document G shown in , press the position designation key 3W. Then, the coordinate position specified by this Sl is stored in the main processor group 71 shown in FIG. Similarly, when the position designation key 3W is pressed with the spotlight moved to 82 points on the document G, the positions of the 82 points are stored in the main processor group 71. The position of this spotlight can be detected, for example, by counting the number of drive pulses of the pulse motor 33,135.

After this, when the erasure range designation key 3c set as shown in FIG. 2(f) is pressed, 8 is shown in FIG. 19(a).
Rectangular area with diagonal points at 1.82 rotation (indicated by diagonal lines)
is specified as the erasure range. Also, as shown in FIG. 19(b), points 83 and 84 of document G are specified, and points 28
As shown in Figure (f), the set erasure range specification key 3
When p is pressed, the area other than the square with the 83.84 rotation as the diagonal point is designated as the erasing range. In this way, when the erasure range designation key 3c or ap is pressed, the main processor group 71 performs calculations based on the positions of the two specified points and the copy magnification, and the memory 140 stores a high level signal in the erasure range. ! ? 11? , the low level signal no'' is stored in the other parts. That is, this memory 140
For example, R is such that the capacitance in each column direction is approximately equal to the movement distance of the spot light source 131 in the X direction ÷ the position resolution in the y force direction.
AM, main processor group 71
In the case of FIG. 19 (a>), as shown in FIG. 20 (a), or as shown in FIG. 19 (
In case b), as shown in FIG. 20(b), a high level signal is stored at the address corresponding to the shaded area, and a low level signal is stored at the other addresses.

In this case, the original is set with the copy side facing up,
After the erasure range has been specified, the document is turned over along the fixed scale 21 of the document table 2. Therefore, as shown in FIG. 2.0, the information stored in the memory 140 is also actually stored inverted in the column direction.

On the other hand, as shown in FIG. 21, an erasing array 150 serving as erasing means is provided close to the photosensitive drum 10, for example, between the charger 11 and the exposure section ph. As shown in FIGS. 22 and 23, this erasing array 150 has a plurality of light shielding cells 151 arranged in a direction perpendicular to the rotational direction of the photoreceptor drum 10, and each of the light shielding cells 151 has a A light emitting element 152 made of a light emitting diode, for example, as shown in FIGS. 24(a) and 24(b) is provided. Further, the light from the light emitting element 152 is transmitted to the opening of each cell 151 facing the photoreceptor drum 10.
A lens 153 is provided to condense light on the surface. The number of light emitting elements arranged in this erasing array 150 matches, for example, the capacity 1 of the memory 140 in the column direction. Here, the distance between the light emitting elements 152 is P, and the number is N.
The total length of the erase array 150 is Q-NXP.

The erase array 150 is driven by the array driver 160 described above. As shown in FIG. 25, this array driving section 160 includes a shift register 161 having the same number of bits as the number of bits in the column direction of the memory 140, and a store register 1 in which the contents of this shift register 161 are held.
62, it is constituted by a switch circuit 164 consisting of a plurality of switch elements 163 that are controlled on and off by each output signal of this store register 162, the movable contacts 163a of these switch elements 163 are installed, and the fixed contacts 163b are erase array 1 via resistor R, respectively.
It is connected to each cathode of the light emitting element 152 constituting 50. The anodes of each of these light emitting elements 152 are connected to the power source CC through current limiting resistors R, respectively.

After specifying the erasing range of the original as described above, when the original cover 11 is closed and the copy key 3-1 is turned on, the first carriage 411 and the photosensitive drum 10 are operated, and the memory 120 is 20th direction
One column of data is sequentially read out (as shown in the figure). This read data D1 is processed by the clock signal CLK.
The data is transferred to the shift register 161 of the array driver 160. After one column of data has been transferred to the shift register 161, when the charged portion of the photosensitive drum 10 reaches the erase array 150, the main processor group 71 outputs a latch signal LTH, and the shift register 161 outputs a latch signal LTH. The signal is supplied to register 162. That is, erase array 150
is disposed between the charger 11 and the exposure section Ph, so that one row of data output from the memory 140 is stored when the angle between the erasing array 150 and the exposure section Ph is θ1.
Assuming that the photosensitive drum 10 is rotating at each speed, the output timing of the latch signal LTH is controlled so that it is supplied to the store register 162 before θ1/ω.

Each switch element 163 of the switch circuit 164 is controlled by the output signal of the store register 162. That is, when the output level of the store register 162 is high level, it is turned on, and when it is at - level, it is turned off. As a result, each switch element 163 is turned on when it is on, and turned off when it is off. Therefore, among the charged parts of the photoreceptor drum 10, the part where the light emitting element 152 is turned on is charge-free, and even if the charge-free part is exposed afterwards, no electrostatic latent image is formed, and the original image is not erased. It means that it was done. Thereafter, the data in the memory 140 is read out column by column in the same manner, and the image is erased.

Next, the display unit 3 using the quick disk device 30
The second operation and voice guidance operation will be explained.

When the main body 1 is powered on, the write flag is turned off in the main processor group 71 in step S1 shown in FIG. 26, and control is transferred to the quick disk subroutine shown in step S2. In this quick disc subroutine, in step SQ1 shown in FIG. 27, it is first determined whether the quick disc set signal output from the quick disc device 30 is at a low level "L", and whether the quick disc Qd is set or not. It is determined whether As a result, if the quick disc Qd is not set, the message "Please set the quick disc", which was previously stored in the main processor group 71 in step SQ2, is displayed on the display control unit 14.
1 to the display unit 32 for display. After this,
In step SQ3, it is determined whether a set time, for example 30 seconds, has elapsed or not. If the set time has not elapsed yet, control is transferred to step SQ1, and if the set time has elapsed, in step SQ4, for example, there is no quick disc. An abnormal termination code (return code) indicating ``is set'', and control is transferred to step S3 shown in FIG.

On the other hand, if it is determined in step SQI that the quick disc Qd is set, step SQ5
A reset signal is sent to the quick disk device 30, and in the quick disk device 30, a motor control flip-flop circuit (not shown) is reset in response to this reset signal so that the motor 173 is not started. When the initial settings of the quick disk device 30 are completed in this way, the high level “HII” is sent from the quick disk device 30.
A ready signal is output. This ready signal is detected in step SQ6, and if the ready signal is not at a high level, it is determined in step SQ7 whether a set time, for example 2 seconds, has elapsed. As a result, if the set time has not yet elapsed, control is transferred to step SQ6, and if the set time has elapsed, a message stored in advance in the main processor group 71, for example, "Quick disk device is abnormal" is sent to step SQ8. It is supplied to the display section 32 via the display control section 141 and displayed. Thereafter, in step SQ9, a return code indicating that the quick disk device 30 is abnormal is set, and control is transferred to step S3 shown in FIG. 26.

If the main processor group 71 determines in step SQ6 that the ready signal is at a high level, it determines in step SQ10 whether or not the write flag is on. In this case, since the write flag is off as described above, the write gate signal is set to low level "L" in step 5Q11, and data can be read from the quick disk Qd. Thereafter, in step SQI 2, the flip-flop circuit of the quick disc device 30 is set and the motor 17.3 is started. Then, it is further determined in step 13 whether the write flag is on or not, and in this case, all data on the quick disk Qd is read out in step 5Q14. This read data is stored in the memory 142. When this read operation is completed, a high-level ready signal is sent from the quick disk device 30, and step 5Q
At step 15, it is determined whether the ready signal has become high level. As a result, if it is determined that the reading has been completed, it is determined in step 5Q16 whether or not the write flag is on. In this case, since it is off, step 5Q17
．． In 5Q18, the same data on the quick disk Qd is read out again in the same manner. In other words, by reading the same data twice, the reliability of the read data is increased.

After that, when it is determined in step 5Q18 that the reading has been completed, the motor of the quick disk device 30 is stopped in step 5Q19, and a return code indicating normal completion is set in step 5Q20, and control is resumed at the 26th step.
The process moves to step S3 shown in the figure.

In step S3, the return code is determined, and it is determined whether the quick disc subroutine has ended normally. If the result is an abnormal termination, control is transferred to step 4, and it is determined based on the return code whether recovery is possible. As a result, if recovery is possible, such as when there is no quick disk, control is transferred to step S1, and if recovery is not possible, the process is terminated.

In addition, if the quick disk subroutine has ended normally in step S3, the memory 1 is
42, display data and voice guidance data corresponding to the operation item data are read out, the display data is supplied to the display section 32 via the display control section 141, and the voice guidance data is The information synthesizer 170 converts the signal into analog audio information, which is then supplied to the speaker 172 via the amplifier 171. Therefore, the display section 32
As shown in FIG. 28(a), each operation key 3a to 3
Operation item data is displayed corresponding to d, 3r, and 3q, and the speaker 172 provides voice guidance "Please select an operation item." In this state, when a desired setting key is pressed, the operation mode is switched to correspond to each item, and the corresponding display and audio guidance are performed. For example, when the setting key 3a is pressed, control is transferred from step S6 to step S7, and the number of sheets setting mode is set. In this step S7, sheet number display data and voice guidance data are read out of the data stored in the memory 142, and this display data is supplied to the display section 32 via the display control section 141. Therefore, the display section 32
As shown in FIG. 28(b), set keys 3e to 3n
Numbers are displayed corresponding to , and the function of a numeric keypad is given to the setting keys 3e to 3n. Further, at this time, the voice guidance data is converted into analog voice information by the voice information synthesizer 170 and supplied to the speaker 172 via the amplifier 171. As a result, the speaker 172 provides voice guidance "Please set the number of copies." In this state, if any of the setting keys 3e to 3n is pressed,
In step S8, the number of sheets corresponding to the pressed setting key is set, and the number of sheets is displayed on the display section 32. After this, the control is transferred to step S9, and it is determined whether or not the copy key 31 has been pressed. As a result, if the copy key 31 is not pressed, the control is switched to step S.

On the other hand, when the setting key 3b is pressed in the display state shown in FIG.
2, and the copy magnification setting mode is set. In step 811, display data and its audio guide data are read out as copy magnification data from among the data stored in the memory 142, and the display data is supplied to the display section 32 via the display control section 141. Therefore, the display section 32
For example, as shown in FIG. 28(C), press the setting key 3.
Magnifications are displayed corresponding to a to 3d and 3p to 3r, and setting keys 3a to 3d and 3p to 3r are each provided with a magnification setting function. Further, at this time, the voice guidance data is converted into analog voice information by the voice information synthesizer 170 and supplied to the speaker 172 via the amplifier 171. As a result, the speaker 172 provides voice guidance "Please set the copy magnification." In this state, when any of the setting keys 3a to 3d and 3p to 3r is pressed, the magnification for the pressed setting key is set in step 813, and the magnification is displayed on the display section 32. After this, the control is transferred to the step S9,
When the copy key 31 is pressed, a copying operation is performed using the magnification set in step S10.

Further, when the setting key 3C is pressed in the display state shown in FIG.
The copy density setting mode is entered. In this step 815, display data and voice guidance data are read out as copy density data from among the data stored in the memory 142, and the display data is supplied to the display section 32 via the display control section 141. Therefore, the display section 32 includes a setting key 3h, as shown in FIG. 28(d), for example.

A density setting display is performed corresponding to 3j. Also, at this time, the voice guidance data is converted into analog voice information by the voice information synthesizer 150 and supplied to the speaker 152 via the amplifier 151. As a result, the speaker 152 provides voice guidance saying "Please set the copy density." In this state, each time the setting key 3h is pressed, the copy density becomes brighter by one step, and each time the setting key 3j is pressed, the copy density is set to become darker by one step.

When the spot light source 131 is moved by operating 5 to 3■ and the desired coordinate position is input using the position designation key 3W,
Control is transferred from step S22 to step 23.

Then, in step 822, the setting key 3C is pressed.

If it is determined by 3p that the erasing range has been designated, it is determined in step 824 whether or not a set time has elapsed. As a result, if the set time has not yet elapsed, the control is transferred to step 822, and if the set time has elapsed, it is determined in step 825 whether or not the setting key 3r has been pressed.

That is, the setting key 3r is used to specify whether or not specified coordinate position data or deletion designation data is to be stored in the quick disk Qd, and if this setting key 3r is not pressed and it is determined that it is not to be stored, Control is transferred to step 826, where it is determined whether the copy key 31 has been pressed. As a result, if the copy key 31 is not pressed, the control is transferred to step S5, and if the copy key 31 is pressed, the control is transferred to step 827. An erasing copying operation is performed on the original document. Then, when the erasing copying operation is completed, a copying operation is performed using the sheet for which control is transferred to step S5.

Further, in step 825, if the setting key 3r is pressed and it is determined that the setting key 3r is to be stored, the control is shifted to step 825.
28, the coordinate position data stored in the main processor group 71 and erasure range data specifying the inside or outside of the designated range are written to a predetermined address in the memory 142. Thereafter, the write flag is turned on in step 829, and control is transferred to the quick disk subroutine in step 830.

In the quick disk subroutine shown in FIG. 27, steps SQ1, SO2, SO2,
QIO and control are transferred, and in step 5Q10 it is determined whether the write flag is on. in this case,
Since it is turned on, it is determined in step 5Q21 whether or not the attached quick disk is write-protected. As a result, if writing is prohibited, in step 5Q22, a message stored in the main processor group 71, such as "Please replace the quick disk", is supplied to the display control unit and displayed. Then, in step 5Q23, for example, 30 seconds, if the quick disk is replaced within this time, the control is transferred to step 5Q21, and if not replaced, an abnormal end return code is set in step 5Q24, and 1lJIll is set. The process moves to step 831.

On the other hand, if it is determined in step 5Q21 that the attached quick disk is not write-protected, the write gate signal is set to a high level in step 5Q25.

After this, in step 5Q12, the quick disk device 30
The motor is started, the write flag is confirmed to be on in step 5Q13, and the data stored in the memory 142 is written to the quick disk QD in step 5Q26. When it is confirmed that all data has been written and the ready signal is set to high level, control is transferred from step 5Q15 to step 5Q16,
It is determined whether the write flag is on or not (2),
Ru. In this case, since it is on, the control is in step 5.
The process moves to Q16, and the motor of the quick disk loading device 30 is stopped. After this, a return code indicating normal completion is set in step 5Q20, and the control returns to step 831.
will be moved to

In this step 831, the return code is determined, and if the completion is normal, control is transferred to the step 826,
If the process has ended abnormally, it is determined in step 832 whether recovery is possible based on the return code. As a result, if recovery is possible, control is transferred to step 826, and if recovery is not possible, the process is terminated.

Next, in the display state shown in FIG. 28 (a>), when the setting key 3q for specifying the erasure range display of the document is pressed, control is transferred from step S33 to 834, and the erasure range display mode is entered.

In this step 834, it is determined whether coordinate position data and erasure range designation data are stored at a predetermined address in the memory 142, and if these data are not stored, control is transferred to step 835. In this step S35, display data stored in the main processor group 71, such as "No erased data is stored," is read out, and this display data is read out from the display control unit 141.
The signal is supplied to the display unit 32 via the display unit 32 and displayed.

Thereafter, if the quick disk QD is replaced, control is transferred to step S1, and if not replaced, control is transferred to step S5.

Further, if it is determined in step 834 that the required data is stored in the memory 142, the required data is read out from the memory 142 in step S36,
It is supplied to the main processor group 71. This main processor group 71 uses the supplied coordinate position data and erasure range designation data to create a memo! , 1140 in Fig. 20 (
Display data similar to those shown in a) and (b) is stored. Thereafter, in step 837, display data is sequentially read from the memory 140 and supplied to the display section 32 via the display control section 141. Therefore, the display section 32 displays FIG. 28 (Q
