Next, the document image erasing means will be explained.

16 and 17, a guide shaft 130 is provided on the first carriage 4 along the lamp 4 in a portion where the light from the lamp 4 is lined up.

A spot light source 131 is movably provided on the guide shaft 130 as a means for indicating the erasing range of the original. As shown in the figure, this spot light source 131117 consists of a light source 132 such as a light emitting diode or a lamp, and a lens 133, which is placed opposite to the document table 2.
The light generated by the lens 132 is transmitted through the lens Iza3.
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 original G set on the original platen 2, 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
4 is a pulley 1 provided on the rotating shaft of the pulse motor 135
36 and driven pulley 137 and I: The hook is passed. therefore.

By rotating the pulse motor 135, the spot light source 13 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 13 is moved.

First, the spot light source 131' comes into contact with the position sensor 138, so that the initial position is detected.

Next, a method for specifying the erasing range of a document using the spot light source 131 will be explained using FIGS. 18 to 20. This spot light source 131 is activated by operating the operation keys 33 to 3v described above while the main processor group 71, which will be described later, is in the document erasure range designation mode.

will be moved. That is, when the operation keys 3t and 3V are pressed, the motor 33 is driven, and the '1p11 carriage 411 and the spot light source 13 are moved in the scanning direction (arrow y shown in FIG. 18).
direction).

When the operation keys ss and 3v 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 J S % J V while visually observing the spot light transmitted through the document G, and specifies the position by moving the spotlight to point Si on the document G, for example, as shown in FIG. 19(a). Press key 3W. Then, the coordinate position specified by S is stored in the main processor m71 shown in FIG. Similarly, with the spotlight moved to point S2 on the document G, the position designation key 3W is pressed and the position of point eS1 is stored in the main processor group 71. The position of this spotlight can be detected, for example, by counting the number of driving pulses of the pulse motors 33, 135. After this, erase range designation key 3? is set as shown in @28 figure (f)? When you press , the Si
, S, a rectangular area (indicated by diagonal lines) with diagonal points is designated as the erasure range. In addition, as shown in Fig. 19 (bl), point Ss and 84 points of the original G are designated, and as shown in Fig. 28 (f
When the erase range designation key 3p set as shown in l is pressed.

The area other than the square whose diagonal points are S,,S, is designated as the erasure range. In this way, erase range specification key 3
When G and 3p are pressed, calculations are performed in the main processor group 11 based on the positions of the two specified points and the copying magnification, and the memory 140 stores a high level signal 11'' for the erasing area and a high level signal 11'' for the other areas. A low level signal ``0'' is stored. That is, in this memory 140, for example, the capacity 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 capacity in each row direction is It is composed of a RAM whose movement distance in the y direction of the spot light source 131 is approximately equal to the position resolution in the y direction, and the first
91m (in the case of al, as shown in Figure 20 (al), and in the case of 'N & 19 (bl), as shown in Figure 20 ('b1), the high level ( 1, and low level signals are stored at addresses other than that.

In this case, the original is set with the copy side facing up, and f
After specifying the P4 area, it is assumed that the document is turned over along the fixed scale 2 of the document 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. R21, an erasing array 150 as an erasing means is provided close to the photosensitive drum 10, for example, between the charger 1 and the exposure section ph. As shown in FIGS. 22 and 23, this erasing play 150 includes a plurality of light shielding cells 1 in a direction perpendicular to the rotation direction of the photosensitive drum 100.
51 are arranged, and each of these cells 151 is provided with a light emitting element 152 made of, for example, a light emitting diode, as shown in FIG.

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 provided in the erasing array 150 matches, for example, the capacity of the memory 140 in the column direction. Here, if the distance between each light emitting element 152 is P and the number of elements is N, the total length of the erasing array 150 is Q=N x P.

The erase array 150 is driven by the array driver 160 described above. This array drive section 160! J25
As shown in the figure, a shift register 161 having the same number of bits as the number of bits in the column direction of the memory 140. Store register 1 that holds the contents of this shift register 161
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 grounded, and the fixed contacts 163b are grounded. Each cathode C of a light emitting element (light emitting diode) 152 constituting the erasing array 150;
It is connected. The anodes of each of these light emitting elements 152 are connected to the power supply vccI via current limiting resistors R, respectively.

After specifying the erase range of the original as described in 11tI, close the original cover 1□ and press the copy key 30, and the v11 carriage 41. As the photosensitive drum 10 is operated, data for one column is sequentially read out from the memory 140 in the row direction (as shown in FIG. 20). 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, the charged portion of the photoreceptor drum 10 reaches the erase array 150.

A latch signal LTH is output from the main processor group 11, and the contents of the shift register 161 are supplied to the store register 162 in response to this signal. That is, erase array 1
50 is arranged between the charger 11 and the g source part Ph, so one column of data output from the memory 140 is as follows.

For example, if the angle between the erase array 150 and the exposure section ph is 01, and the photosensitive drum 10 is rotating at an angular velocity ω, the latch signal LTH is output so that it is supplied to the store register 162 before θ, /ω. Timing is controlled.

Each switch element 163 of the switch circuit 164 is controlled by each output signal of this store register 162. That is, 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 one light emitting element 15i is turned on is charge-free, and even if this charge-free part is subsequently exposed to light, no electrostatic latent image is formed, and the document image is erased. It means that it was done. Thereafter, data in the memory 140 is read out column by column in the same manner, and one image is erased.

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

When the main body 1 is powered on, the write flag in the #i main block set group 21 is turned off in step S1 shown in FIG. 26, and step S! Quick disc indicated by
Control is transferred. In this quick disk subroutine, step SQ1 shown in FIG.
First, it is determined whether or not the quick disk set signal output from the quick disk VpW 130 is at a low level 1L", and it is determined whether or not the quick disk Qd is set in the quick disk device @lso. 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 7 in step SQ" is displayed on the display section 3. through the display control section 141. I=supplied and displayed. After this, step 8Q
In s, it is determined whether the set time 1, for example 30 seconds, has elapsed or not.

If the set time has not elapsed (%), the control is transferred to step SQt, and if the set time has elapsed, an abnormal termination code (
Return code) is set, and control is transferred to step Ss shown in FIG.

On the other hand, if it is determined in step SQ that the quick disc Qd is set, step 8Qs
A reset signal is sent to the quick disk device 30, and in response to this reset signal (2), a motor control flip-flop circuit (not shown) is reset so that the motor (not shown) does not start. When the initial settings of the quick disk device W1.30 are completed, the high level '
A ready signal of "H" is output. This ready signal is detected in step sQa, and if the ready signal is not at level 1, step SQ? Then, it is determined whether a set time of 1, for example, 2 seconds has elapsed. As a result.

If the set time has not yet elapsed, control is transferred to step 8Qa, and if the set time has elapsed, a message stored in advance in the main processor group 11, for example, "Quick disk device is abnormal" is displayed in step 8Qs on the display control section. 141, the display unit 3. supplied and displayed. After this, in step SQ, the quick disk device 30
A return code is set indicating that the
The control is transferred to stitch Ss shown in FIG.

Further, if it is determined that the ready signal is at a high level in step SQs, then step SQ
t. It is determined whether the write flag is on or not. In this case, as mentioned above, the write flag is off, so
At step 8Qo, the barokomi gate signal is at low level "l"
L1'', and data can be read from the quick disk Qd. Thereafter, in step 5Qit, the first flip-flop circuit of the quick disk device 30 is set and the motor is started.

Then, further step SQ1. It is determined 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 memory 142. When this read operation is completed, a high-level ready signal is sent from the quick disk unit @SO, and step 8Q*s
Then, 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 8 Qze whether the write flag is on or not. In this case, since it is off, step 8 Qsy
-S Qts, the same data on the quick disk Qd is read out again in the same way. In other words, 18I-data f2
By reading the data multiple times, the reliability of the read data is increased.
