Filed: 1990-07-28
Abstract: PURPOSE:To clear off complicated operations in the case of non-voice system communication service by transmitting the movement of a transmission lever to a coin sorter by a linking plate and the transmitting mechanism of an interlocking lever and further directly operating the interlocking lever by a solenoid. CONSTITUTION:When pushing down a middle plate lever 4, a coin return state is set up and when the pushing-down is released and the middle plate lever 4 is raised, a coin selectable/storable state is set up.

Title: Switch for electric shutter for building
Inventor: NIWANO YUICHI
IPC: E06B9/70
Filed: 1999-07-14
Abstract: PROBLEM TO BE SOLVED: To make an interior finishing of a switch compact by housing a driving motor and a substrate in a casing in a manner being aligned in a longitudinal direction of a motor shaft. SOLUTION: A driving motor 10 is housed in a casing such that a substrate 11 for controlling drive of the motor 10 is also housed in the same. The substrate 11 and the driving motor 10 are housed in the casing in a manner being aligned in a longitudinal direction of a motor shaft of the driving motor 10, and therefore the thickness of the casing can be made slender even with provision of the substrate 11, relative to a casing in which the substrate is arranged in a radial direction of the motor shaft, which leads to miniaturization of the casing. In this case, the casing is elongated in the longitudinal direction of the motor shaft, but the length of the casing extends in the same direction as the longitudinal direction of a winding wheel, which imposes no inconvenience.  A case main body 8 of the substrate housing chamber assumes shallow setting, and therefore attaching/detaching work of the substrate 11 is need not be carried out in a deep position, which enhances workability.
