Next, the document image erasing means will be explained.

In FIGS. 16 and 17, the first carriage 41! A guide shaft 130 is provided along the lamp 4 in a portion where the light of the lamp 4 is blocked, and a spot light source 1 is provided on this guide shaft 130 as a means for indicating the erasing range of the document.
31 is movably installed. As shown in FIG. 17, this spot light source 131 consists of 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 light emitting element 132 is transmitted through the lens. 133, the document table 2 is irradiated with 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. In addition, the spot light source 131 is connected to the guide shaft 13.
It is connected to a timing belt (toothed belt) 134 disposed along 0. This timing belt 13
Pulley 13 provided on the rotating shaft of 4-pulse motor 135
6 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. Also, the first carriage 41 located at the end of the guide shaft 130 on the pulse motor 135 side!
A position sensor 138 consisting of a microswitch is provided to detect the initial position of the spotlight 11i131. 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 spot light source 131 is moved by operating the operation keys 3S to 3■ described above while 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 3■ are pressed, the motor 33 is driven, and the first carriage 411 and spot light source 131 are moved in the scanning direction (arrow y shown in FIG.
direction). Further, when the operation keys 3S and 3u are pressed, the motor 135 is driven, and the spot light source 131 is moved in a direction perpendicular to the scanning direction (in the direction of arrow X shown in FIG. 18). The operator operates the operation keys 38 to 3v while visually observing the spot light transmitted through the document G.
9. With the spotlight moved to point S1 on the document G shown in FIG. 9(a), the position designation key 3W is pressed. Then, this Sl
The coordinate position specified by is stored in the main processor group 71 shown in FIG. Similarly, when the spot light is moved to 82 points on the document G and the position specification key 3w is pressed,
The positions of the 82 points are stored in the main processor group 71.

The position of this spot light is controlled by a pulse motor 33.1, for example.
This can be detected by counting the number of 35 drive pulses. Thereafter, when the erasure range designation key 3c set as shown in FIG. 2(f) is pressed, a rectangular area (Ss) with 82nd rotation as the diagonal point (
) is designated as the erasing range. Also, the first

m, lit, and press the set erase range designation key 3p as shown in Figure 28(f), the area outside the square area with 83.84 rotation as the diagonal point is specified as the erase range. be done. In this way, when the erasure range designation keys 3c and 3p are pressed, the main processor group 71 performs calculations based on the positions of the two designated points and the copy magnification, and the memory 140 stores a high level signal in the erasure range. ``1'', and a low level signal ``0'' is stored in the other portions.In other words, the capacity of this memory 140 in each column direction is approximately equal to the moving distance of the spot light source 131 in the X direction ÷ the position resolution in the y direction. Consists of matched RAM,
Based on the data supplied from the main processor group 71,
In the case of Fig. 19 (a), as shown in Fig. 20 (a), and in the case of Fig. 19 (b), as shown in &f Fig. 20 (b), it corresponds to the shaded part. A high level signal is stored at the specified address, and a low level signal is stored at 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. 20, the information stored in the memo 1 140 is also actually stored inverted in the column direction.

On the other hand, as shown in FIG. 21, an erasing array 150 as a tit 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 erase array 150 is
A plurality of light shielding cells 151 are arranged in a direction perpendicular to the rotational direction of the photoreceptor drum 10, and these light shielding cells 151
As shown in FIGS. 24(a) and 24(b),
A light emitting element 152 made of, for example, a light emitting diode is provided. Furthermore, a lens 153 is provided in the opening of each cell 151 facing the photoreceptor drum 10 to focus the light from the light emitting element 152 onto the surface of the photoreceptor drum 10 .

The number of light emitting elements arranged in this erasing array 150 matches, for example, the capacity of the memory 140 in the column direction. Here, if the distance between the light emitting elements 152 is P and the number is N, the total length of the erasing 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 pits 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, a plurality of switch elements 16 that are turned on and off by each output signal of the store register 162;
The movable contacts 163a of these switch elements 163 are installed, and the fixed contacts 163b4 are connected to each cathode of the light emitting elements 152 constituting the erasing array 150 via the respective resistors R. It's 6s. The anode current I11 of each of these light emitting elements 152 is connected to the power supply VC through the limiting resistor R, respectively.
Connected to C (do.

After specifying the erasing range of the original as described above, when the original cover 11 is closed and the three copy keys 1 are turned on, the first gear 1 knob 411 and the photosensitive drum 10 are operated, and the memory 2nd row from 120
One column of data is sequentially read out (shown in FIG. 0). 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, the eraser 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 low 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 operation of 2 and the voice guidance operation (will be explained with reference to X).

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 disk subroutine, at step SQI shown in FIG. Even if Qd is set, it is determined whether the force is \ or not. As a result, if the quick disk Qd is not set, the message stored in the main processor group 71 in advance in step SQ2, for example, "Please set the quick disk"&N PI
The message is sent to the display unit 3 via the display control unit 141.
2 and displayed. After that, in step SQ3, it is determined whether or not a set time, for example 30 seconds, has elapsed. If the time has not elapsed yet, control is transferred to step S01, and if the set time has elapsed, step SQ
For example, an abnormal termination code (return code) indicating that there is no quick disk is set in 4, and the control is switched to the 26th
The process moves to step S3 shown in the figure.

On the other hand, if it is determined in step SQ1 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 quick disk device 30 outputs a high level “HI+” signal.
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. Display III til1
The signal is supplied to the display section 32 via the 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.

Further, if the main processor group 71 determines that the ready signal is at the no level in step SQ6), it determines whether the write flag is on or not in step SQ10. In this case, as mentioned above, the write flag is turned off and becomes 0, so the write gate signal is set to low level +tL'' in step SQI1, and data from the quick disk Qd can be read.After this, , the flip 70 knob circuit of the quick disc device 30 is set in STETSU 7SQ12, and the motor 17
3 is activated. Further, in step 13, it is determined whether the write flag is on or not, and in this case, in step 5Q14, all data on the quick disk Qd is read out. This read data is stored in the memory 142. When this read operation is completed, the quick disk device 30 sends out a high-level ready signal.
In step 5Q15, 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 the write flag is on or not. is read out. In other words, by reading the same data twice, the reliability of the read data is increased. After that, if it is determined in step 5Q18 that the reading has been completed, the motor of the quick disc device 30 is stopped in step 5Q19, and in step 5Q2
