Title: Photosensitive material packing unit
Inventor: SHIBA KEISUKE
IPC: G03B19/02
Filed: 1989-04-13
Abstract: PURPOSE:To offer a photosensitive material packing unit attached with a compact photographing function by using a photographing lens at a long focal distance, and using a reflecting mirror to fold an optical axis. CONSTITUTION:In the film unit attached with the lens, an optical axis 63a ahead of a photographing lens 63 is folded in a Z shape in a plane orthogonal to both a film surface and a film feed direction by two mirrors 35 and 36, further since the mirror 35 is arranged directly under the photographing lens 63, the optical path length ahead of the photographign lens 63 can be extended while a unit main body 10 is being made compact, and thus the film unit attached with a telescope type lens can be obtained. Further an exposure allowable range (ES) of each silver halide photosensitive layer unit by a white exposure is expanded. A single lens at the focal distance of 50 to 150mm is attached to the packing unit main body, which directly houses the color photosensitive material or houses the material in a containner, as the photographing lens.

IPC: G11B19/00
Filed: 1986-04-23
Abstract: PURPOSE:To move quickly a card by providing a shuttle for placing a recording medium and a rotary body having a cam engraved on its periphery interlocking with the shuttle. CONSTITUTION:When a motor 1 is driven counter clockwise, a gear 4a fitted to a ring 4 is driven via a pinion 2 to drive the ring 4 clockwise. A cam slot 3 is also driven by the drive of the ring 4 to drive a roller 8 of the shuttle 5 engaged with the cam slot 3, since the roller 8 is restricted by a guide shaft 7, the shuttle 5 is moved straight in the direction of arrow A. The straight forward movement of the shuttle 5 is halted when a detection member 10b fixed under a retaining spring 9 is sensed by an interrupter 11. Since the shuttle is moved by the cam slot, the shuttle is reciprocated by driving the motor unidirectionally only to read the information on a card quickly. In loading the card to the shuttle, the shuttle is fixed surely by reversing the motor.
