Title: Laser radar device
Inventor: YASUDA SHIYOU
IPC: G01W1/00
Filed: 1982-04-15
Abstract: PURPOSE:To form transmitting and receiving shutters which are stable and high in practical use, by slightly varying the number of revolutions of choppers of transmitting and receiving optical systems, and controlling the emission of a laser by a state of a synchronizing signal. CONSTITUTION:A pulse laser emitted from a laser oscillator 1 passes through a transmitting optical system 3 through a reflector 2 and is sent out in the sky by reflectors 5, 6. On the other hand, rear scattered light is condensed by a Cassegrain optical system consisting of a primary reflector 7 and a secondary mirror 8, passes through an interference filter 10 and is received by a photodetector 11. Transmitting and receiving high-speed rotating shutters 4, 9 are used for transmission and reception, respectively. A photoelectric pickup detector 24 monitors a rotating state of a synchronizing motor 21, and transmits a pulse whenever a blade hole 22 coincides with a laser beam 23 position. A synchronizing motor 25 of high-speed rotation for a receiving chopper is slightly shifted from the motor 21 as to its number of revolutions.

Title: Sheet stacking device
IPC: B65H39/11
Filed: 1992-03-19
Abstract: PURPOSE:To secure a work space largely, and facilitate a jammed paper sheet removing work by arranging a part of a sheet conveying section independently in a cover member, forming a sheet receiving section cooperatively of the cover member and a main body, and constituting the cover member so as to be opened/closed with the lower edge part as its swing center. CONSTITUTION:The second conveying section 1500 is arranged on the reverse side of a cover member 1110, and is formed as a conveying section independent from a conveying section of a main body. The lower edge part of the cover member is supported with a shaft 1516 so as to be capable of swinging freely on a frame 1120 of the main body 1100. Thereby, when the jamming of a paper sheet is caused, the cover member 1110 is opened by using the handle 1112. In that case, since there exists no obstacle around the second conveying section, a required process is only to pull out a clogged paper sheet from between a feed roller 1508 supported with the second guide plate 1502 and a pinch roller 1514. Since the first guide plate 1208 is exposed in a receiving section 1200 and a lower guide plate 1622 is exposed in the third conveying section 1600 simultaneously, the jammed paper sheet can be removed.
