摘要： This invention provides an image capturing apparatus which sets the spectral characteristics of a split light beam to be substantially equal to those of straight traveling light upon splitting a light beam coming from a photographing optical system and enables an autofocus detection function by the split light with a sufficient light amount. A digital camera includes a photographing optical system, beam splitter, focus detection sensor, polarizing filter, and CMOS sensor. The beam splitter splits a light beam which travels toward the CMOS sensor that receives an object image formed by the photographing optical system, depending on the direction of polarization, and the focus detection sensor performs focus detection based on the light beam split by the beam splitter. The polarizing filter removes substantially the same polarized light component as a polarized light component that travels toward the focus detection sensor as a result of splitting by the beam splitter.

摘要： A loading mechanism includes a frame and a tray on which an information recording medium is placeable. The tray includes a groove part and is movable between a first position where the information recording medium is contained completely inside the frame and a second position where the information recording medium is exposed completely outside the frame. The loading mechanism further includes at least three projections arranged on the frame at predetermined intervals along the sliding directions of the tray. The projections include first and second guide and support parts forming the first and second ends of the arrangement of the projections. The first and second guide and support parts come into substantially point or linear contact with the groove part of the tray so as to guide and support the tray when the tray is in the second position.
