Focal plane shutter and image sensing apparatus

An image sensing apparatus comprising:

• a focal plane shutter that is arranged on an optical axis of the image sensing apparatus between an imaging optical assembly for imaging an object light image and a light receiving section for receiving the light image from the imaging optical assembly, the focal plane shutter being operable to block the object light image from being incident on the light receiving section from the imaging optical assembly,
• the focal plane shutter including:
• a group of shutter blades;
• a driving member that drives the shutter blades in a certain direction in a predetermined order;
• a shutter bedplate formed with an opening for passing the object light image from the imaging optical assembly;
• and
• a shutter base plate formed with an opening for passing the object light image from the imaging optical assembly,
• the shutter bedplate and the shutter base plate being aligned substantially in parallel with each other in the optical axis direction, and arranged on a side of the imaging optical assembly and on a side of the light receiving section with respect to the group of shutter blades, respectively,
• the opening of the shutter base plate has a size larger than a size of the opening of the shutter bedplate and a size of the light receiving section,
• the light receiving section having a light receiving plane substantially parallel with the focal plane shutter for receiving the object light image through the focal plane shutter,
• an imaging optical assembly that images the object light image on the light receiving section, and a driving section that drives the light receiving section in two
• directions perpendicular to each other on an imaging plane of the imaging optical assembly, wherein the light receiving plane of the light receiving section is moved within a region of the opening of the shutter bedplate viewed from a direction of a normal line to the shutter bedplate, and
• a shake detecting section that detects a shake of the image sensing apparatus and outputs a shake detection signal indicative of the shake of the image sensing apparatus, and a shake correction controlling section that generates a shake correction amount and a shake correcting direction for canceling the shake, based on the shake detection signal outputted from the shake detecting section, wherein the driving section drives the light receiving section based on the shake correction amount and the shake correcting direction generated in the shake correction controlling section.
