Title: Electrostatic recorder
Inventor: YUASA KAZUHIRO
IPC: G03G15/22
Filed: 1983-10-05
Abstract: PURPOSE:To improve image quality and to reduce cost by charging electrostatically uniformly both front and rear surfaces of a recording medium to the polarities opposite from each other, forming an electrostatic latent image on said recording medium by a thermal recording means according to the image signal and developing the electrostatic latent image. CONSTITUTION:The outside surface 1a of a dielectric belt 1 is uniformly charged negatively and the inside surface 1b positively by scorotron chargers 3a, 3b which are disposed to face each other with the belt 1 in-between. An electrostatic latent image is formed on the belt 1 by the thermal recording means of a thermal head 5 provided right under a platen roller 4 on the down stream side of the chargers 3a, 3b. The latent image on the surface 1a is developed by a developing device 6 provided on the outside of the belt 1 on the down stream of the writing position. Since the surface of the electric belt on the opposite side of the writing position is developed, the thermal head is kept free from staining by a toner, etc. The image quality is thus improved and the cost is reduced.

Title: Feed holding circuit for camera
Inventor: UCHITOI MASANORI
IPC: G03B7/26
Filed: 1982-10-21
Abstract: PURPOSE:To prevent improper feeding operation due to a failure in contacting and impedance by feeding and keeping on feeding a camera under the control of a transistor (TR) driven by switches corresponding to the 1st and the 2nd strokes of the camera. CONSTITUTION:When film winding is completed and a switch SW5 is connected to a contact NC to close a switch SW1 in the 1st stroke of shutter releasing, a TR1 connecting with a power source BAT turns on to feed a photometric arithmetic part, etc. Then when a switch SW2 is closed in the 2nd stroke, the output of the inverter 202 of a sequence control and automatic exposure part is inverted to a high level and the output of the NAND gate 102 of an FF305 is also raised to a high level, thereby lowering the output of an inverter 203 to a low level. Consequently, even if the switch SW1 is turned off, the TR1 is still turned off and the feeding operation is held. This system which does not utilize the intervention of a mechanical switch prevent trouble such as an increase in power consumption, etc., due to a failure in contacting and impedance.
