Abstract
A shutter charging device for a focal plane shutter with which a stable charging time can be obtained and frame speed can be improved during continuous capture. A shutter charging device charges a focal plane shutter device comprising an opening and a first curtain blade and second curtain blade that can block off the opening. The shutter charging device comprises a charging member that drives the first curtain blade and the second curtain blade in a predetermined sequence, a gear component that includes a drive gear for driving the charging member one sequence by each rotation and transmits the rotation of a DC motor to the charging member, and a lock lever that stops the drive gear. The lock lever operates so as to stop the drive gear at a predetermined timing within one sequence.

A shutter charging device for charging a shutter device, the shutter device equipped with an opening and first and second curtains capable of blocking off the opening, said shutter charging device comprising:
- a driver configured to drive the first and second curtains in a predetermined sequence;
- a gear component configured to include a drive gear that drive the driver just one sequence by each rotation, and transmit a rotation of a motor to the driver;
- and
- a brake member configured to stop the drive gear,
- wherein the brake member operates so that the drive gear stops at a predetermined timing in said one sequence.
A shutter device comprising:
- first and second curtains capable of blocking off an opening;
- a driver configured to drive the first and second curtains in a predetermined sequence;
- a gear component including a drive gear configured to drive the driver only one sequence by each rotation, and to convey a rotational force to the driver;
- and
- a brake member configured to stop the drive gear;
- wherein the brake member operates so that the drive gear stops at a predetermined timing in one sequence.
