BLADE OPENING/CLOSING DEVICE AND IMAGING APPARATUS
Document Type and Number:
Japanese Patent JP2023002302
Kind Code:
A
Abstract:
To provide a blade opening/closing device capable of easily visually recognizing the opening/closing state of a blade member from the outside.SOLUTION: A blade opening/closing device 1 includes a base part 10 in which a base opening 11 is formed and a cover part 30 which covers the base part 10. A cover opening 31 is formed in a position adjacent to the base opening 11 of the base part 10 in a Z direction, in the cover part 30. The blade opening/closing device 1 further includes a blade member 40 which is movable along an X direction inside a blade chamber formed between the base part 10 and the cover part 30. The blade member 40 has a light-emitting part 41 capable of emitting light. The blade driving device 1 includes an actuator 20 which moves the blade member 40 to a closing position so that at least a part of the light-emitting part 41 of the blade member 40 is exposed from the cover opening 31 and retreats the blade member 40 to an opening position so that the cover opening 31 communicates with the base opening 11.SELECTED DRAWING: Figure 2
