IPC: G02B7/28
Filed: 1987-12-01
Abstract: PURPOSE:To simplify an optical system for defocusing detection to facilitate adjustment of a photodetector at the time of assembling by including the photodetector to the locus line of an image forming point described by the deviation between an information forming layer and a light condensation point. CONSTITUTION:When an optical information recording medium 1 is in the focus position of an objective lens 2, the luminous flux reflected on the optical information recording medium 1 is converted to parallel rays of luminous flux through the objective lens 2 and is condensed on a focus position P by a condenser lens 3. A multi-divided photodetector 4 is arranged in the focus position P of the condenser lens 3 and is inclined to the optical axis of the objective lens 2 and the condenser lens 3. When the optical information recording medium 1 is in the focus position of the objective lens 2, the photodetector 4 is moved longitudinally along the optical axis in the vicinity of the focus position P of the condenser lens while being inclined to the optical axis, and the photodetector 4 is fixed in the position where the number of turned-on cells is minimum. Thus, defocusing is detected by the simple constitution of the optical system and the position adjustment for assembling is facilitated.

Title: Platen roller for heat transfer type recorder
Inventor: IIDA AKIHIKO
IPC: B41J11/02
Filed: 1991-10-24
Abstract: PURPOSE:To prevent extension of a circumferential length at the time of bringing a thermal head into pressure contact, and to prevent degrading in quality of a picture, particularly generation of color deviation, by forming a thin layer made of at least resin having a high elastic modulus on a peripheral surface of an elastic layer of a platen roller. CONSTITUTION:A platen roller 10 comprises a shaft 10a made of metal, etc., an elastic layer 10b applied coaxially on the outer periphery of the shaft 10a, a thin layer (a high elastic modulus resin layer) 10c made of resin having a high longitudinal elastic modulus and covering the outer periphery of the layer 10b, and a thin layer (a high frictional layer) 10d made of a material having a high frictional coefficient such as rubber, etc., and applied on the outer periphery of the layer 10c. The layer 10c is formed by laminating resin having a high longitudinal elastic modulus. The higher the modulus is, the higher an effect of preventing an elongation of a circumferential length of the layer 10b becomes, but the layer 10b is scarcely deformed, and hence its thickness is reduced thereby making a pressure uniform at the time of bringing into pressure contact. Since the elastic material such as rubber, etc., of the layer 10d is sufficiently reduced in thickness the deformation at the time of bringing into pressure contact does not become a problem and can be ignored.
