Abstract: A pair of angular contact bearings 20A, 20B are disposed between a bearing house 16b of an inspection head 16 and a head supporting tube 8, and a spacer 25 and a spring bearing ring 26 are disposed between outer races 20o of the bearings 20A, 20B. The spacer 25 and the spring bearing ring 26 are urged by a coil spring 27 toward the side of the outer race 20o. An O-ring 28 is disposed between the spacer 25 and the outer race 20o of the bearing 20B, and the outer circumference of the O-ring is brought into closely contact with the inner circumference of the bearing house 16b. The outer races 20o are constrained by a step part 16f in the bearing house 16b and an end cap 29 screwed into the inspection head 16. Removing the end cap 29 makes it possible to take out the bearing housing 16b and a main shaft part 16c integrally from atop of the bearings 20A, 20B.

Abstract: A method for correcting the focus at plural image positions in a reproducing camera system in which plural images are to be formed on a photosensitive material, the supporting base for which can vary in flatness from position to position. Prior to exposure of the photosensitive material, values are stored in a memory for each image position indicative of the amount of deviation of that position from a reference flat position. For the exposure of each image position, the corresponding value is read out and applied to an automatic lens positioning system to thus correct the focus for each image position.

Abstract: A method of preventing the occurrence of blackened margins on a photosensitive sheet processed in an electrophotographic apparatus. The method comprises the steps of calculating a first sheet transporting length by which the photosensitive sheet is required to be transported until the forward end of an image area of the photosensitive sheet within which an image is allowed to be formed is charged with electricity and a second sheet transporting length by which the sheet is required to be further transported until the rear end of the image area is charged with electricity. A charging device is caused to turn ON when the actually transported length of the photosensitive sheet attains the calculated first sheet transporting length, and then is deactuated to turn OFF when the additionally transported length of the photosensitive sheet attains the calculated second sheet transporting length.

Abstract: A mechanism for cutting film supplied in the form of a long strip into segments having a predetermined length and transporting the segments to a subsequent processing stages wherein cutting, positioning and holding of the film are performed substantially simultaneously with an apparatus having a simple construction. A film suction platen is provided having a plurality of holes formed therein. A lowered pressure is provided on the side of the platen opposite that on which film segments of a predetermined length are fed from a supply reel. A cutting mechanism is mounted alongside the platen to cut the segments after they have been fed. After the segments have been cut, and following exposure while on the film suction platen, the film suction platen is reciprocated to a take-out section which extracts the exposed film segments from the surface of the film suction platen and feeds them to the processing stage.
