Title: Impact absorption device and electrical device provided with the impact absorption device
Inventor: KAGAMI YOSHIJI
IPC: F16F7/00
Filed: 1991-10-15
Abstract: PURPOSE:To protect an electrical device by actuating an impact absorption body when the electrical device falls down. CONSTITUTION:An air bag unit 1 is housed in a main unit 9 with a rid 12 and an air bag unit 2 is housed in a display cage 10 with a rid 13. When a tilt detection mechanism 5 detects that the electrical device is tilted enough to fall down, a detection signal is transmitted to the air bag unit 1 or 2 and the air bag unit receiving the signal is expanded. Accordingly, the electrical device is protected from the impact of the fell-down electrical device. A touch sensor 3 is mounted on the cage surface of a handle unit 11 easily accessible by a user and a touch sensor 4 is mounted on the cage surface of the main unit 9 easily accesible by the user. With these touch sensors, the signal from the tilt detection mechanism can be ignored and the air bag unit can be prevented from expanding even when the tilt of the device takes place during operation.

Inventor: WAKUI MASAJI
IPC: H04N1/00
Filed: 1986-11-11
Abstract: PURPOSE:To start reading from a prescribed position without errors by abutting on a travelling original, detecting a shift quantity and starting reading as soon as the shift quantity reaches a prescribed value. CONSTITUTION:A titled equipment is constituted in such a way that a shift quantity detection means 18 is provided in proximity to a feedout roller 3 and an original 1 which has been separated in the roller 3 and has been fed out enters between a detection roller 19 and a pinch roller 20 to rotate the roller 19. With the shift of the original 1 by the roller 3, a rotary encoder 21 generates a pulse signal which is proportional to the shift quantity through the roller 19. The number of the generated pulses from the encoder is counted, and if the number of the pulses reaches a prescribed number, the reading of the original 1 starts. Consequently, the original 1 passes through a clearance between guide boards 11' and 12' and reaches a reading position. A read means 17 reads the contents from the position where a tip part overreaches for prescribed quantity. Thus, reading can be started from the prescribed position without errors.
