Next, the document image erasing means will be explained.

In FIGS. 16 and 17, a guide shaft 130 is provided along the lamp 4 in a portion where the light of the lamp 4 is blocked on the first carriage 41, and this guide shaft 130 is provided with a guide shaft 130 for holding the document. Spot light source 1 as a means of indicating the erasing range
31 is movably provided. This spot light source 1
As shown in FIG. 17, 31 is a light emitting element 132, such as a light emitting diode or a lamp, provided opposite to the document table 2.
The light generated by the light emitting element 132 is directed to the document table 2 with a diameter d.
It is designed to be irradiated as a spot light.

This spot light has a brightness that allows it to pass through the document G, which is set on the document table 2Vc and is, for example, as thick as a postcard.

In addition, the spot light source 131 has a timing belt (toothed bell) 13 disposed along the side axis 1 and to.
It is connected to 4. Is this timing belt 134 NoJ? Pulley 13 provided on the rotating shaft of Luz motor 135
6 and the driven pulley 137. Therefore, as the pulse motor 135 is rotated, the syspot 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 on the first carriage 411 located at the end 1c of the pulse motor 135 side of the guide 8130. In this case, first, the spot light source 131 comes into contact with the position sensor 138, and the initial position is detected.

Next, a method for specifying the erasing range of a document using the spot light source 131 will be described with reference to FIGS. 18 to 20. This spot light source 131 is moved when the main processor group 71 (described later) operates the operation keys 31 to 3 while the main processor group 71 is in the document erasure range designation mode. That is, when the operation keys 3t and 3ma are pressed, the motor 33 is driven, and the first carriage 411 and the spot light source 131 are moved in the scanning direction (arrow y direction shown in FIG. 18) K.

Further, when the operation keys J, , 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 presses the operation key 3 while visually observing the spot light transmitted through the document G.
For example, the document G shown in FIG. 19 (&) is
With the spotlight moved to the upper point S1, 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 specifying key 3w is pressed with the spotlight moved to 82 points on the document G, the position of the sS1 point is stored in the main processor group 71. The position of this spot light can be detected, for example, by counting the drive pulse number of the pulse motor 33, 1.95. After that, when the erase range designation key 3c set as shown in FIG. 28(f) is pressed, <S, I> as shown in FIG. 19(a) is pressed.
A rectangular area (indicated by diagonal lines) with the point s as the diagonal point is designated as the erasing range. Also, as shown in Fig. 19(b), 83 points + 84 points of the original G are designated, and as shown in Fig. 28(f)
When you press the erase range designation key 3p set as shown in
S.

The area other than the square with 84 diagonal points is designated as the erasing range. In this way, erase range specification key J c
* When you press Jp, the main processor group 71 performs calculations based on the specified two-point positions and the copying magnification, and the memory 140 stores a high-level signal "l" in the erased area and a high-level signal "l" in the other parts. In other words, in this memory 140, the capacity in each column direction is approximately equal to the position resolution of the spot light source 13 in one direction in the movement distance divided by the X direction, and the capacity in each row direction is is constituted by a RAM K whose movement distance in the y direction of the switch light source 131 is approximately equal to the position resolution in the y direction.
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 Fig. 20(
As shown in b), low level signals are stored at addresses other than the address K/s irregular signal and sore corresponding to the shaded area.

In this case, the original is set with the copy side facing up, and after the erasure range is specified, it is turned over along the fixed scale 21 of the original table 2.

Therefore, the information stored in the memory 140 shown in FIG. 20 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 includes a plurality of light shielding cells i in a direction perpendicular to the rotational direction of the photoreceptor drum 10.
As shown in FIG. 24 (al a (b)), each cell 151 is provided with a light emitting element 152 made of, for example, a light emitting diode. A lens 153 that focuses the light from the light emitting element 152 onto the surface of the photoreceptor drum 10 is provided in the opposing opening.
The number of light emitting elements arranged in the memory 14 is, for example,
It is matched with the column direction capacitance of 0. 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 16 in which the contents of this shift register 161 are held.
2. 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 the store register 162. The movable contacts 163a of these switch elements 163 are grounded, and the fixed contacts 163b are connected to each cathode of a light emitting element (light emitting diode) 152 constituting the erasing array 150, respectively. The anodes of each of these light emitting elements 152 are connected to the power supply Vcck through current limiting resistors Ri.

After specifying the erasing range of the original as described above, when the original cover 11 is closed and the copy key 301 is pressed, the first carriage 411 and the photoreceptor drive 510 are operated, and the memory 140 is Data for one column is sequentially read out in the row direction (shown in FIG. 20). This read data DI is transferred to the shift register 161 of the array driving section 160 according to the clock signal CLK. After data for one column of shift register L6111C is transferred, the charged portion of the photosensitive drum 10 is transferred to the erase array 15.
When it reaches 0, the main processor group 71 outputs a shift signal LTH, and the contents of the shift register 161 are supplied to the store register 162 in response to this signal. That is, since the erasing array iso is arranged between the charger 11 and the exposure section ph, one column of data outputted from the memory 140 is stored, for example, when the angle between the erasing array 150 and the exposure section ph is al. The photoreceptor drum 10 has an angular velocity ω
Assuming that the latch signal LT)I is rotating at .theta.1/.omega., the output timing of the latch signal LT)I is controlled so that it is supplied to the store register 162 before .theta.1/.omega.

Each switch element 163 of the switch circuit 164 is controlled by each output signal of this store register 162. When the output signal of the store register 162 is at a high level, it is turned on, and when it is at a low level, it is turned off. As a result, the light emitting elements 152 connected to each switch element 163 are turned on when the switch element 163 is on, and are turned off when the switch element 163 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, data in the memo IJ 140 is read out column by column in the same manner, and images are erased.

Next, the display unit 3 using the quick disk device 30
Operation 1 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 S8. In this quick disk subroutine, in step SQ1 shown in FIG. 27, it is first determined whether the quick disk set signal output from the quick disk device 30 is at a low level "L", and the quick disk is set to the quick disk device gt30. Q
It is determined whether or not d is set. As a result,
If the quick disk Qd is not set, a message "Please set, for example, 1 quick disk" stored in advance in the main processor group 71 in step SQs is supplied to the display section 33 via the display control section 14. After this, in step SQs, it is determined whether or not a set time, for example 30 seconds, has elapsed.
If the set time has not elapsed, control is transferred to step SQr. If the set time has elapsed, an abnormal termination code (return code) indicating, for example, that there is no quick disk is set in step SQ4, and control is transferred to the steps shown in FIG. Transferred to Ss.

On the other hand, if it is determined in step SQI that the quick disk Qa is set, step SQi
A reset signal is sent to the quick disc device 30, and in the quick disc device 30, in response to this reset signal, a motor control fritz defrozzo circuit (not shown) is reset so that the motor (not shown) does not start.

When the initial setting of the quick disk device 30 is completed in this way, the high level 1H is sent from the quick disk device 30.
' ready signal is output. This ready signal is detected in step SQ-, and if the ready signal is not a no-repel signal, it is determined in step SQγ whether a set time, for example, 2 seconds has elapsed. As a result, if the set time has not yet elapsed, the control is transferred to the step SQ-, and if the set time has elapsed, the first quick disk device stored in advance in the main processor group 71 by the Steg SQ controller is abnormal. This message is displayed by the display control unit 141.
The signal is supplied to the display unit 33 via the display unit 33 and displayed. After this.

A return code indicating that the quick disk device 30 is abnormal is set in Stella fsQ-, and the control is switched to the second
The process moves to step S3 shown in FIG.

Further, if it is determined in step SQ- that the ready signal is at a high level, step 5Q
At so, it is determined whether the write flag is on or not. In this case, since the write flag is off as described above, the write dart signal is set to low level in step 5QII.
It is set to "L" and data can be read from the quick disk Qd. Thereafter, in step 5Qss, the clip-flop circuit of the quick disk device 30 is set and the motor is started. And further step 8
Qss determines whether the write flag is on or not, and in this case, the data on the quick disk Qd is read out in step 5Q14. This read data is stored in the memo 171.
42. When this read operation is completed, the quick disk device 30 sends out a ready signal of no.
It is determined whether or not the % error has occurred. As a result, if it is determined that the reading has been completed, step 5Q1a
It is determined whether the write flag is on or not. In this case, since it is off, the same data on the quick disk Qa is read out again in the same manner at step 5Qty*5Qts. 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 5Qxs that the reading has been completed, the motor of the quick disk device 30 is stopped in Stellar fsQts, a return code indicating normal completion is set in step 5Qzo, and the control returns to the 26th step.
