Next, the means for erasing the original drawing will be explained.

In Figures 16 and 17, the 1st gear, Ji 41! A guide shaft 13o is provided along the lamp 4 in a portion where the light of the run f4 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 original.
31 is movable (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.
and the lens 133, the light generated by the light emitting element 132 is directed to the document table 2 with a diameter d.
The K is set so that it is irradiated as a spot light. This spot light has a brightness that can transmit the document G set on the document table 2 and has a thickness of, for example, a postcard. Belt (toothed belt) 13411
C-connected. This timing belt 134 is passed between a pulley 136 and a driven pulley 137 provided on the rotating shaft of the Norsmoke 1350. Therefore, when the pulse motor 135 is rotated, the light source 131 is moved in a direction perpendicular to the scanning direction of the first carriage 411. In addition, a position sensor 138 consisting of a microswitch that detects the initial position of the spot light source 131 is provided on the first intermediate spear 411Vc located at the end of the guide shaft 130 on the Noyars motor side. In this case, first, the spot light source 131 comes into contact with the position sensor 138 to detect the initial position.

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 by operating the aforementioned operation keys 38 to 3 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 3v 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).

Further, when the operation keys 3m 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 (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.
8 to 3 to move the spotlight to the point S on the document G shown in FIG. 19(a), for example, and then press the position designation key 3w. Then, the coordinate position specified by S is stored in the main processor group 71 shown in FIG. Similarly, when the position designation key 3w is pressed while the light has been moved to 82 points on the document G, the position of the 82 points is stored in the main processor #71. The position of this spot light can be detected, for example, by counting the number of driving nozzles of the gusset motors 33 and 135. After this, when the erasure range designation key 3C set as shown in FIG. 28(f) is pressed, as shown in FIG. 19(a) K<St+8
A rectangular area (indicated by diagonal lines) with two diagonal points is designated as the erasing range. Also, as shown in FIG. 19(b), points 83 and 84 of the original G are specified, and the erase range specified as shown in FIG. 28(f) =? - When you press jp,
The area other than the square with 8B+84 points as diagonal points is designated as the erasing range. In this way, erase range specification key 3
When c and 3p are pressed, calculations are performed in the main group 7 based on the specified two point positions and the copying magnification, and the memory 140 stores a high level signal "11" in the erase area and other In other words, in this memo +7140, the capacitance in each column direction is approximately equal to the movement distance in the X direction of the spot light source 131 divided by the position resolution in the X direction, and the capacitance in each row direction is The RAM is configured by a RAM whose capacity is approximately equal to the moving distance of the spot light source 131 in the X direction divided by the position resolution in the y and X directions.
In the case of Fig. 9 (,), as shown in Fig. 20 (,), and in the case of Fig. 19 (b), as shown in Fig. 20 (b)
As shown in the figure, a high level signal is stored in the address corresponding to the shaded area, and a low level signal is stored in the other addresses.

In this case, the original is set with the copy side facing up, and after the erasing range is specified, it is turned over along the fixed scale 2K 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 1 in a direction perpendicular to the rotation direction of the photoreceptor drum 100.
51 are arranged, and inside each of these 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. Further, the opening of each cell 151 facing the photoreceptor drum 10 is exposed to light from a light emitting element 152.

A lens 153 that focuses light on the surface of the body drum 100 is provided. The number of light emitting elements arranged in this erasing array 150 matches, for example, the capacity of the memory 1400 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-N.
It becomes XP.

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 pits in the column direction of the memory 1400, 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 163& of these switch elements 163 are grounded, and the fixed contacts 163b are connected to each quadrant of light emitting elements (light emitting diodes r) xsz constituting the erase array 150, respectively. The anode of each of these light emitting elements 152 is connected to the power supply V via a current limiting resistor R, respectively. cVc connected.

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, the camera 411 and the photosensitive drum IQ are operated, and the memory 140 is Data for K1 columns in the row direction (shown in FIG. 20) is sequentially read out. This read data D1 is read out according to the clock signal CLK.

The data is transferred to the shift register 16 of the ray driver 160. After one column of data is transferred to the shift register 16, the charged portion of the photosensitive drum 1o is transferred to the erase array 1.
50, the main processor group 71 outputs a siratch signal LTH, and in response to this signal, the contents of the shift register 161 are supplied to the store register 162 I/C. That is, the erase array 150 includes the charger 1 and the exposure section ph.
For example, the angle between the erasing array 150 and the exposure section ph is 01, and the photosensitive drum 10 rotates at an angular velocity ω. If the latch signal LTH is supplied to the store register 162 before θl/ω,
output timing is controlled.

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, 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 z will be explained.

When the power of the main unit 1 is turned on, the write flag in the main process 71 is turned off in step S1 shown in FIG.
Control is transferred to the subroutine. In this quick disk subroutine, in step SQl shown in FIG. It is determined whether or not the tie and disc Qd are set. As a result, if the quick disc Qd is not set, in step SQz, a message, for example, "Please set the quick disc", which has been stored in the main processor group 71 in advance, is displayed on the display unit 32 via the display control unit 141. Supplied and displayed. After this, it is determined in step SQs whether a set time, for example 30 seconds, has elapsed;
If the set time has not elapsed yet, control is transferred to step SQ1, and if the set time has elapsed, step f3Q is executed.
For example, an abnormal termination code (return code) indicating that there is no quick disk is set at step a, and control is transferred to step fs shown in FIG.

On the other hand, if it is determined in step SQs that the tie and disc Qd are set, step SQs
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 frig 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 ``H'' is output from the quick disk device 30.
A ready signal is output.

In step SQs, this ready signal is detected, and if the ready signal is not at a high level, it is determined in step SQy 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 SQs, 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 SQa. Display unit 3 via display control unit 14! supplied and displayed. Thereafter, in step SQe, a return code indicating that the quick disk device 30 is abnormal is set, and control is transferred to step S3 shown in FIG.

Further, if it is determined in step SQa that the ready signal is at a high level, step SQa
At lo, it is determined whether the write flag is on. In this case, as mentioned above, the write flag is off, so
In step 5QII, the write r-) signal is set to low level ``L''.
”, and data can be read from the quick disc Qd. After that, in step 5Qri, the flip f70 knob circuit of the quick disc device 30 is set and the motor is started. 5Ql
At step s, it is determined whether the write flag is on or not, and in this case, the data from the quick disk Qd is read at Stella 7'5Q14. This read data is stored in the memory 142.
is memorized. When this read operation is completed, a high level ready signal is sent from the quick disk device 30, and it is determined in step SQ1g whether or not the ready signal has become high level.

As a result, when it is determined that the reading has been completed, it is determined in Stella 7'5Qts whether the write flag is on or not. In this case, since it is off, step 5Qxy l
At 5Qts, the same data on the quick disk Qd is read out again in the same manner. By reading the same data twice, the reliability of successive data is increased.
