摘要： There is provided a blade drive device including a substrate that has an opening, a front curtain and a rear curtain that are movable along an opening surface of the opening so as to open and close the opening, a front curtain locking portion that interlocks with opening and closing operations of the front curtain, a rear curtain locking portion that interlocks with opening and closing operations of the rear curtain, and a regulation lever that is configured to be pivotally movable around a lever axis, and that is capable of entry and escape between an entry position which enters each operation trajectory of the front curtain locking portion and the rear curtain locking portion in response to the opening and closing operations of the front curtain and the rear curtain and an escape position escaped from the operation trajectory. The regulation lever has a front curtain regulation portion which can be locked by the front curtain locking portion from one side around the lever axis at the entry position so as to regulate movement of the front curtain in a closing direction, and a rear curtain regulation portion which can be locked by the rear curtain locking portion from the other side around the lever axis at the entry position so as to regulate movement of the rear curtain in a closing direction.

摘要： A focal-plane shutter capable of stabilizing a curtain in continuous photographing action for suppression of variation in light exposure period is provided. The focal-plane shutter includes a base plate having a first opening, a blade receiving plate so arranged as to face the base plate and having a second opening formed in a position corresponding to the first opening, and a rear curtain that is arranged between the base plate and the blade receiving plate and moves between an open position where the first opening and the second opening are open and a closed position where the first opening and the second opening are closed to open and close the first opening and the second opening. The blade receiving plate has a protruding section in a position where the blade receiving plate overlaps with the rear curtain located in the open position when viewed along the optical axis direction, and the protruding section so protrudes toward the rear curtain as to allow the rear curtain to come into contact with the protruding section.

摘要： A standard camera with means for using non-imaging light for activating the film when taking pictures in low light conditions. The film activating means consists of an LED strip mounted on the primary blind or blade of a focal plane shutter of a standard camera, and placed adjacent to the trailing edge thereof. The LED strip is illuminated when the shutter mechanism is activated and the strip will be moved across the film gate area to activate the film just before the light from the subject strikes the film to produce the image thereon. In this manner, none of the subject light is used for activating the film and a better picture results. The LED light can comprise three lights of blue, green and red and the brightness of these three lights may be individually controlled to obtain different photographic effects on the film.

摘要： 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.
