An imaging device includes an image sensor having a plurality of chromatic color pixels and high-sensitivity pixels having higher sensitivity to incident light than the chromatic color pixels arranged in a checkerboard pattern, a correlation detector that detects correlation of an imaged subject from a signal component of the high-sensitivity pixels and a signal component of the chromatic color pixels, a color judgment block that judges whether or not the imaged subject is of chromatic color from the signal component of the chromatic color pixels, and a pixel interpolator that switches between pixel interpolation methods according to the signal judged in the color judgment block that judges whether or not the subject is of chromatic color, the pixel interpolator giving high priority to interpolation using pixels showing strong correlation based on the information from the correlation detector when the color judgment block judges that the subject is of chromatic color.

The invention includes a base member attached to a casing. The inside of the casing can be a vacuum atmosphere. A partition wall is provided on the base member, the base member separating an air atmosphere and the vacuum atmosphere. A rotating member (a rotating portion of a driving source) is provided on the base member at a position different from the rotating member. An armature, which is a dust source, is provided on the air atmosphere side of the partition wall, thereby maintaining high cleanliness on the vacuum atmosphere side. Providing the partition wall and the rotating member at different positions eliminates the necessity of consideration on the rigidity of the partition wall for supporting the rotating member, thereby reducing the thickness of the partition wall. In addition, it is possible to reduce affection by deflection generated by the inertia or vibration caused by rotation of the rotating member, so that a distance between the armature and a magnet in the rotating member can be narrower than the related art. Accordingly, high accuracy in stopping positions can be realized.

A method of overheating and releasing a chip cut piece from a thermal release type pressure sensitive adhesive sheet is a method by which a chip cut piece stuck onto a thermal release type pressure sensitive adhesive sheet having a base material, and a thermally expandable microsphere-containing thermally expandable pressure sensitive adhesive layer provided on a surface of the base material is thermally released from the thermal release type pressure sensitive adhesive sheet and which is characterized by including the step of overheating while restraining the overheat and release type pressure sensitive adhesive sheet to thereby release the chip cut piece. A means for restraining the thermal release type pressure sensitive adhesive sheet may be an absorption means using suction or may be a bonding means using an adhesive agent. In this manner, the chip cut piece can be thermally released from the overheat and release type pressure sensitive adhesive sheet while position displacement in a horizontal direction can be prevented.

The electric shaver in accordance with the present invention comprises a hand grip 10 configured to be gripped by a user's hand, and a blade head 20 provided on an upper end of the hand grip. The blade head carries at least one shaving unit 50 comprising an outer blade foil 70 and an inner blade 80 driven in a shearing engagement manner with the outer blade foil. The outer blade foil has a plurality of holes in which hairs are introduced. The outer blade foil is elongated and has a length, and is curved along a width direction to form a generally C-shaped cross section, and is curved convexly and uniformly along its length to have a longitudinal curved outline. The feature of the present invention resides in that a radius of curvature of the longitudinal curved outline is 150 mm to 350 mm.

A cartridge detachably mountable to an apparatus includes a drum, a developing roller, first and second frames supporting the drum and roller, a coupling member rotatably connecting the frames, a first cartridge positioning portion abuttable to a first main assembly positioning portion positioning the cartridge with respect to a direction crossing the drum axis when the cartridge is mounted to the apparatus, a drive input gear engaging a main assembly driving gear, and a second cartridge positioning portion abuttable to a second main assembly positioning portion limiting cartridge rotation about the first cartridge positioning portion. When the cartridge is in the apparatus, the coupling member crosses a phantom line perpendicular to the second main assembly positioning portion and which passes through the second positioning portion, as seen from one end with respect to the axis.
