Digital camera including focal plane shutter
There is provided a digital camera that can suppress the generation of vibration caused by the operation of a shutter. One end portion of a camera body ( 10 ) forms a grip region ( 10 A), and a drive unit ( 120 ) of a focal-plane shutter unit ( 110 ) is disposed within the range of the grip region ( 10 A). Further, a battery ( 92 ) is disposed between an image sensor ( 70 ) and a display unit ( 100 ) at an end portion of the camera body opposite to a grip region ( 10 A). Since the drive unit ( 120 ) of the focal-plane shutter unit ( 110 ) is disposed within the range of the grip region ( 10 A), a portion of the camera body, which is close to the center of rotation of a shutter curtain, can be gripped with a hand at the time of handheld imaging. Accordingly, the generation of vibration can be effectively suppressed. Further, since the battery ( 92 ) is disposed at the end portion of the camera body opposite to the grip region ( 10 A), the moment of inertia about the grip region ( 10 A) can be increased. Accordingly, the generation of vibration can be more effectively suppressed.
1. A digital camera comprising:
a camera body of which one end portion is formed as a grip region;
a lens or a lens mount that is provided on a front subject side of the camera body;
a display unit that is provided on a back of the camera body;
an image sensor that is provided in the camera body;
a focal-plane shutter unit which is square, includes a drive unit for a shutter curtain, provided at one end portion of a base plate including an exposure aperture, the shutter curtain opening and closing the exposure aperture, and is disposed immediately in front of the image sensor in the camera body, and of which the drive unit is disposed in the grip region, which includes a protruding portion protruding toward the subject side and functions as a finger hook, the grip region configured to receive a hand of a user to grip the camera body at a time of handheld imaging; and
a battery that is disposed between the image sensor and the display unit in the camera body, and is disposed at an end portion of the camera body opposite to the end portion of the camera body forming the grip region.
2. The digital camera according to claim 1 ,
wherein 80% or more of a region of the drive unit of the focal-plane shutter unit is disposed in the grip region.
