摘要： A film conveying apparatus includes a portion for feeding a film, a portion for drawing the film and a slack detecting apparatus for detecting slack of the film therebetween. The slack detecting apparatus includes a light emitting portion and the light receiving portion, and when the light from the light emitting portion to the light receiving portion is intercepted by the film, it is determined that the film has slack. When the slack of the film is detected by the slack detecting apparatus, emission of light from the light emitting portion is stopped for a prescribed time period.

摘要： A scanning optical apparatus for a printer and a digital copying machine has a light source, a deflector, first and second imaging units. The deflector deflects a light beam emitted from the light source to a main scanning direction. The first imaging unit makes the light beam emitted from the light source form an image in the vicinity of the deflection position of said deflector in the sub-scanning direction. The first imaging unit has a first resin lens having a negative refractive power only in a sub-scanning direction. The second imaging unit makes the light beam deflected by the deflector form an image on a scanned surface in the sub-scanning direction. The second imaging unit has a second resin lens having a positive refractive power only in the sub-scanning direction.

摘要： A laser beam optical scanning device which has a laser diode, a collimator lens, a cylindrical lens, a polygonal scanner and an f .theta. lens. The polygonal scanner is made of resin, and when the polygonal scanner is driven to rotate, the reflective facets of the polygonal scanner are distorted to be concave or convex because of a centrifugal force. If the reflective facets are distorted to be concave with rotation of the polygonal scanner, the image surface shifts along the optical axis toward the polygonal scanner. Therefore, in this case, the elements of the optical scanning device are positioned such that the image surface is located behind a light receiving surface while the polygonal scanner is stationary and is located nearer to the light receiving surface while the polygonal scanner is rotating.

摘要： A laser beam optical scanning system having a laser diode, a collimator lens, a cylindrical lens, a polygonal mirror and an f.theta. mirror. The f.theta. mirror has a free toric surface whose curvature in the main scanning direction varies in accordance with field angle. The variation of the curvature of the free toric surface is set in accordance with the position of the f.theta. mirror in the optical path, and this appropriate setting of the variation of the curvature enables the f.theta. mirror to correct both distortion and curvature of field in the main scanning direction.
