A wheel rolling bearing unit capable of preventing grease leak even if the interference of the sealing member for sealing the clearance between the inner and outer rings is made small. The wheel rolling bearing unit according to the present invention is equipped with an inner shaft; an outer ring disposed concentrically on the outer peripheral side of the inner shaft; a plurality of balls disposed between these; and a pair of cages for retaining the balls in the circumferential direction. On the inner peripheral surface of each of the pair of cages, a concave section being dented to the outside in the radial direction to hold grease is formed in the range from the axial outside end section to the inside end section.

An object of the present invention is to provide a base generator which has sensitivity and is applicable to a wide range of applications, and a photosensitive resin composition which is applicable to a wide range of applications due to the structure of a polymer precursor in which reaction into a final product is promoted by a basic substance or by heating in the presence of a basic substance. The base generator generates a base by exposure to electromagnetic radiation and heating. The photosensitive resin composition comprises a polymer precursor in which reaction into a final product is promoted by the base generator and a basic substance or by heating in the presence of a basic substance.

Provided is a printer capable of reliably combining a main unit and a detachable unit with each other, performing smooth attachment/detachment operation of the detachable unit, easily achieving miniaturization, and suppressing interference with fingertips during the attachment/detachment operation, to thereby increase safety. The printer includes: a main unit (10) including opposed walls (62); and a detachable unit (11) combined with the main unit so as to be attached to/detached from the main unit freely. The detachable unit includes: an engagement pin (50) protruding along an axial line which is non-coaxial and parallel with respect to a platen shaft of a platen roller (5); and a lock pin (51) movable relative to the engagement pin. The opposed walls each include: a first recess (65) and a second recess (66) allowing the engagement pin and the lock pin to be fitted detachably therein, respectively. The engagement pin is incapable of being detached from the first recess when the lock pin is fitted in the second recess, and is capable of being detached from the first recess after the lock pin is detached from the second recess.

Provided is a printer with a cutter, which can easily restore, even when there arises a problem that a movable blade is stopped during sliding due to paper jam or the like, the movable blade to a state before the problem arises, reliably perform positioning between a movable blade frame and a detachable unit, and improve printing accuracy and cutting accuracy. A detachable unit (4) turns in a sliding direction of a movable blade (32) from a mounted position to a dismounted position. Meanwhile, a movable blade frame (33) turns in a direction orthogonal to the sliding direction of the movable blade (32) from a home position to a separated position. Thus, the both blades (32 and 11) retreat in directions orthogonal to each other, respectively.

an object of the present invention is to provide a printer with a cutter, which has a compact structure to allow for the reduction in size and is capable of performing printing while eliminating an unprinted area as much as possible and of easily performing recovery without wasting a recording sheet even if a paper jam occurs during the printing. Provided is a printer with a cutter including a platen roller 10 for feeding a recording sheet, a fixed blade 11 provided adjacent to the platen roller, a fixed blade holder 12 having one surface 11a for fixing the fixed blade thereon and another surface 11b being opposed to an outer peripheral surface of the platen roller, and a holder support 13 having an opposed surface 13a being opposed to the outer peripheral surface of the platen roller on a downstream side of the holder in a rotating direction of the platen roller, for rockably supporting the fixed blade holder, in which the another surface of the fixed blade holder is formed to be curved along the outer peripheral surface of the platen roller and guides the recording sheet toward the downstream side in the rotating direction of the platen roller when the recording sheet gets into a gap between the fixed blade holder and the platen roller.

Durability of cutting performance of a fixed blade and a movable blade is increased to downsize a device as a whole and to reduce manufacture costs thereof. The device includes a flat fixed blade (21), a flat movable blade (22) having a blade edge allowed to perform horizontal movement with respect to the fixed blade (21) in directions approaching and departing from a blade edge of the fixed blade (21), a drive mechanism (23) for moving the movable blade (22) with respect to the fixed blade (21), and spacers (28) for forming a predetermined gap according to a thickness of a sheet material (5) between the blade edges (21a) and (22a) in a thickness direction of those when the blade edges (21a) and (22a) of the fixed blade (21) and the movable blade (22), respectively, intersect with each other.

A recording unit has an illuminating device for projecting light on an original to form an original image, and an optical device which focuses the original image formed by the illuminating device. A light control plate has a slit for allowing a portion of the original image focused by the optical device to pass through. The light which passes through the slit of the light control plate is guided onto a print head which ejects ink on a recording medium when exposed to the light.

A printer has a main unit supporting one of a platen roller and a recording head and has a movable blade, a movable blade holder holding the movable blade, a reciprocating mechanism for reciprocating the movable blade holder to slide the movable blade, a drive gear that drives the reciprocating mechanism, a motor that rotationally drives the drive gear, and a gear train mechanism that transmits a rotational force of the drive gear to the reciprocating mechanism. A detachable unit supports the other of the platen roller and the recording head and has a fixed blade for cutting the recording sheet in association with the movable blade. The detachable unit is attachable to and detachable from the main unit and moves close to and away from the main unit along a sliding direction of the movable blade when the detachable unit is attached to and detached from the main unit.
