Abstract

PURPOSE:To control the scanning start of a plate picture by the movement of an original platen and to simplify the constitution of a copying device by moving an original platen at the copying of the plate picture in addition to the copying time of an original. CONSTITUTION:The copying device is provided with a box body 2 of a copying process part 1, a box body 28 of a plate writing part, a movable original platen 10, etc. an original copying mode is set up by a copy command key switch 16 on the box body 2, and at the copying of an original, a photosensitive body 3 is rotated. At the copy of a plate picture, a power switch 30 arranged on the box body 28 side is depressed, the depression is detected by a detecting switch 31 and a motor 21 is actuated by a control circuit 32 and a motor driving circuit 33. Then, a field lens 27 is abutted or made close upon/to the original platen 10 by depressing the switch 16. The original platen 10 is separated from the switch 13 and the plate picture starts to be scanned in response to a signal formed by the switch 31. Thus, the constitution of the copying device can be simplified.

When the cover member 29 is retracted, the field lens 27 is retracted to a position above the document table 10. This evacuation position is platform 10
Used in copy mode for originals placed on the In the board copy mode, no original is placed on the original table 10, and the field lens 27 allows the original placed on the original table to face the imaging optical system 8 in the copy mode. The optical system 8 faces the optical system 8 at substantially the same position (where the original image is projected onto the photoreceptor 3 by the optical system 8) in the board copy mode. Therefore, the image of the board formed on the field lens 27 is transferred and re-imaged onto the photoreceptor 3 by the optical system 8. In this way, the optical path inside the box body 2 can be shared for both modes, and there is no need to provide a separate optical path, so there is no need to make major modifications to the conventional copier, and the configuration can be simplified.

When copying a board document, an operator turns on a power switch 30 provided on the board box body 28 side. As a result, the detection switch 31, control circuit 32, and motor drive circuit 33 enter a standby state, and as soon as the drive circuit 33 is energized, the motor 2
1 becomes operational. Next, the operator presses switch 16.
is turned ON (at this time, the field lens 27 is in contact with or close to the document table 1o as described above), the above-mentioned 3.
The means 15 to 15 operate in the same way as in the copying mode for the original placed on the document table, but in the board copy mode, when the document table 10 starts moving forward in the direction of the arrow from the position shown in the figure, the table 10 is separated from the switch 31 which was in contact with it in the position shown, and scanning of the board is started in response to the signal generated by the switch 31 due to this separation. That is, the signal generated by the switch 31 is transmitted to a control circuit 32 including a timer, and the control circuit 32 detects the leading edge of the copy of the image written on the board 18 after a predetermined time from the time when the above-mentioned signal is generated, or at the same time. The drive circuit 33 is energized at a timing that enables the transfer material to be transferred in alignment with the leading edge of the transfer material. When the drive circuit 33 is energized, the motor 21 operates and the member 1
8 moves in the direction of the arrow. At this time, the lamps 22 and 23 are turned on and the board image is scanned, but the scanning speed
That is, the moving speed of the board member 18 is the speed of advancing the document table 10 (that is, the scanning speed of the document placed on the table 10) divided by the imaging magnification of the board document onto the field lens 27 by the lens 26. is set to . When the member 18 moves a predetermined amount, the control circuit 32 de-energizes the drive circuit 33;
The movement of member 18 is stopped.

In any case, while the member 18 is moving, the image written on the board is projected onto the field lens 27, and the rigging lO is also sliding against the field lens 27 or passing through a minute gap. It is something that moves forward.

The control circuit 32 may use a timer signal to de-energize the drive circuit 33, for example, at the same time as the document table 10 finishes moving forward.

If the distance from position A where writing can be done on the board 18 to reading position B is long, turn on the switch 30 to move the member 18 once and wait until the leading edge of the board to be copied is just in front of position B. You may also do so.

Further, although the switch 31 is provided in a fixed position by a stay or the like fixed to the box body 28, the switch 31 is not at the position where it detects when one unit 10 starts moving forward in the direction of the arrow, but when the unit 10 starts moving forward. Alternatively, if a document table is used that uses a position other than the one shown as its home position and moves once from there to the position shown when the switch 16 is turned on, the table 10 that is in the middle of its movement may be provided at the position where it is detected. In any case, the switch 31 is arranged at such a position that the member 18 can start moving at the timing when the leading edge of the copied image on the board coincides with the leading edge of the transfer material. Also switch 3
The detector 1 is not limited to a microswitch, but any other detector such as a photocoupler can be used as long as it can detect the table 10 under the action of the table 10.

Further, in the illustrated example, the board member 18 is moved and scanned, but the board member 18 may be held stationary and the mirror is moved to scan.

Furthermore, in the illustrated example, the endless board member is circulated in one direction, but the member 18 is an end member, and it is wound around one shaft during scanning, and unwound around another shaft after scanning is completed. You can do it like this.
