Document Type and Number:
Japanese Patent JP2016102992
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a blade driving device capable of switching a blade smoothly, even when being miniaturized.SOLUTION: A coil bobbin 31a fixed to a base 6 is arranged so as to cross a rotation radius of a holding frame 4, and the holding frame 4 can be supported and simultaneously moved circularly by a rotary shaft 9 of the base 6. Hereby, even when an actuator 7 with a small torque constituted of an iron core 27, permanent magnets 28, 29 and an air-core coil 31 is applied in order to miniaturize a device, the holding frame 4 can be reciprocated smoothly.SELECTED DRAWING: Figure 1
