Title: Image recorder
Inventor: TAMURA YASUYUKI
IPC: B41J2/44
Filed: 1980-10-16
Abstract: PURPOSE: To record a thin line, etc. with extremely high accuracy in a beam scan, by changing the intensity of the laser beam which is scanned by the image signals concerning the scanning carried out before and after the first beam scanning.  
     CONSTITUTION: An image signal VN is supplied to an NOT circuit, and at the  same time image signals NN -1  and NN +1  concerning the scanning carried out before  and after the signal VN and supplied to a NOR circuit. In this case, the signals NN -1  and NN +1  show only a non-picture parts and are accordingly set at a low level respectively. As a result, the output of NOR is set at a high level, and transistors (TR)Q 3  and Q 1  are turned on. Under such conditions, if the N-th beam is at the non-picture part, the signal VN is set at a low level and thus receives the level inversion by the NOT. Thus a TRQ 2  is turned on. As a result, an intesive laser beam LB is generated from a laser generating semiconductor DL to indicate the non- image part on a photoreceptor. When the beam scanning is carried out at an image part, no LB is produced from the semiconductor DL to show an image on the photoreceptor.

Filed: 1988-06-13
Abstract: PURPOSE:To spread plates one by one efficiently and safely regardless of materials of the plates and aligne them at optional intervals by providing a Z-shaped fixed guide plate near the supply conveyor end part. CONSTITUTION:When plates A-D are reached to the end of a supply conveyor 1, they are slipped down to the lower side 21 of a Z-shaped fixed guide plate, and received by a first receiving lever 3, which is gently fallen down to left with absorbing the shock to make the Z-shaped middle side 22 of the fixed guide plate support the piled-up plates A-D. Then, a force lever 4 is driven to bring up the whole of the plates A-D. When the top plate A of the brought-up plates exceeds the height of the middle side 22, it slides on the Z-shape upper side 23 and advances to left. This is received by a second receiving lever 5, which is then driven and fallen down to left, whereby the end of the plate A is brought into contact with a sending-out conveyor 9. Thus, by operating the carrying-out conveyor at a proper speed, the plate A is moved to thereon and carried to left.
