Title:
ROTOR LOCK MECHANISM AND ROTATING PLATE DRIVING APPARATUS
Document Type and Number:
Japanese Patent JP2014130266
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a rotor lock mechanism achieving low power consumption, miniaturization and space saving, and to provide a rotating plate driving apparatus including the rotor lock mechanism.SOLUTION: A rotary shutter apparatus 1 (rotating plate driving apparatus) includes first and second motors 50A, 60A for rotating first and second shutter plates 20, 30, and a shutter lock mechanism 80 for locking the first and second shutter plates 20, 30 respectively on predetermined stop positions. The shutter lock mechanism 80 includes an engagement recess 84 formed on an annular plate 83 to be rotated integrally with a first rotation shaft 53, and a locking motor 81 arranged on the outside of a through part 82 of a first motor housing 11. When the locking motor 81 is rotated forward, a shaft 81a is advanced and engaged with the engagement recess 84 to form a lock state. When the locking motor 81 is reversely rotated, the shaft 81a is retreated and separated from the engagement recess 84 to form an unlock state.
