摘要： PURPOSE:To discriminate whether each synthesized information is obtained from different originals or not by charging conditions to form plural images different in picture quality in a copying device for synthesized copying plural image information on one copy sheet. CONSTITUTION:The 1st original is set up on a prescribed position by an original replacing device 1, the image of the 1st original is transferred to transfer paper 10 through an illuminating/exposing optical device 5, a photosensitive body 6, a developing device 8, and a transfer drum 11 and the transfer paper 10 is stored in a storing device 13. The 2nd original is set up by the original replacing device 1, and the image of the 2nd original which is formed on the photosensitive body 6 is transferred and synthesized on the same surface as the 1st original image of the transfer paper 10. The image formation of the 1st original is executed by the normal copying process, but in case of the 2nd original, a net point pattern forming screen 45 in used to form a network point copy or a charging condition, a transfer condition or a developing bias voltage is changed to discriminate respective originals.

摘要： PURPOSE:To synthesize and transfer a piece of information at random from plural originals without troublesome work by installing a setting stand available from arraying plural pressure sensitive elements on either an original platen setting an original or an original replacing device. CONSTITUTION:A reference position display 34 setting an original at a place setting the original directly to be writer and the setting stand 36 equipped with plural pressure sensitive elements 35 are installed. On the setting stand 26 originals 22 or 23 are placed, and a point showing the composite area of the original or the range of an information area 37 is pressurized. A pressure signal from the pressurized pressure sensitive element 35 stores the composite area or the information area in a controller. The setting stand 36 can be placed on the original platen 38. Thus the indication of the picture area where the original is transferred and the indication of a position where the picture is transferred and reproduced can be easily carried out.

摘要： PURPOSE:To enable the specified scanning exposure to be done by one charging and optical unit even at its forward and backward moving by connecting the charging unit and optical unit relatively displaceably within the specified direction in their moving directions. CONSTITUTION:An optical unit 7 carries a yoke-form engaging lever 19 by means of a pin 18 vertically movably and this lever 19 engages in the engaging recess 22 formed in a charging unit by either one of the engaging pawls 20, 21 of both end parts thereof, thereby connecting the charging system 6 and optical system 7. In addition, the lever 19 is acted with the downward spring force by a spring 23 and is connected to the plunger 25 of the solenoid 24 to the optical system 7, so that, while the solenoid 24 is not energized, the lever is displaced downward by the action of the spring 23 and engages into the recess 22 and, while the solenoid 24 is being energized, it detaches from the engagement with the recess 22. As a result, the charging system 6 moves in procedence to the optiacal system at its both forward and backward movement, whereby the sepecified voltage may be applied.
