摘要： PROBLEM TO BE SOLVED: To provided paper comer bend preventing mechanism by arranging a free passage space for a paper corner part in the part matching with a cas sette jaw in the width direction in a paper guide in the substantially top part of a U-turn conveying path on the inside. SOLUTION: A paper sheet fed out from a paper feeder on the upper side or on the lower side is fed into paper conveying rollers. Therefore, the first U-turn conveying path 27 and the second U-turn conveying path 28 are positioned close to each other while putting the first U-turn paper guide 29 between them. The width of the first U-turn paper guide 29 is smaller than that of the second U-turn paper guide 30, and on both sides of the first U-turn paper guide 29, free passage areas 31 for curled parts (a) generated in the left and right corners at the tip of a paper sheet 12 are formed in the positions matching with a pair of left and right cassette jaws inside a paper feed cassette 2. In this way, the space for the second U-turn conveying path 28 can be used as the space for the free sections 31 for the curled parts (a) generated in the left and right corners at the tip of the paper sheet 12.

摘要： PROBLEM TO BE SOLVED: To reuse flanges by providing the flanges, etc., for rotatably supporting a photoreceptor to be easily removable from the photoreceptor. SOLUTION: Fixing means are provided on the flanges 21 fitted to both ends of the pipe stock 1a of a photoreceptor rum 1 to fix the flanges 21 on the pipe stock 1a or release the fixation, so that the flanges 21 can be reduced. The fixing means are provided with fixing members 24 which are provided in the flanges 21 and movable in radial directions centering on shaft holes 20, so that the fixing members 24 partly protruded into the shaft holes 20 are pushed out toward the outer peripheries of the flanges 21 by fixing pins 26 inserted into the shaft holes 20. Therefore, the end faces corresponding to the outer peripheries of the flanges 21, of the fixing members 24 come into strong press-contact with the inner periphery of the pipe stock 1a of the drum 1, to fix the flanges 21. When the fixing pins 26 are removed from the shaft holes 20, the flanges 21 can be easily removed from the pipe stock 1a of the drum 1.

CONSTITUTION: In a paper sheet containing device for a copying machine or the like, in the case of supplying paper sheets to an upper main body part 6 in a closed condition, the upper main body part 6 is opened in an upward direction A. By rotation of a gear 8 in a direction B in accordance with this rotation of the upper main body 6, a rack 23 is moved in a direction D through gears 12, 13, 15, and a pinion gear 20, and a back end side position regulation means 3 is moved integrally with this move of the rack 23. In this condition, the sheets are supplied into a lower main body part 1, with their ends set along right/left end regulation means 4, 5. By closing the upper main body part 6 after supply of the paper sheets, the back end side position regulation means 3 is moved to a sheet regulation position, and tips of the sheets are applied to a tip side position regulation means 2 to be arranged.

摘要： PURPOSE:To provide a paper feed device by which paper feed from a paper sheet receiving part is smoothly performed by means of a simple structure by providing a changeover means to change over a projecting posture to project a paper sheet regulating member regulating the width direction of a sheet from a transport passage according to the size of a sheet, and a receiving posture not to project from the transport passage. CONSTITUTION:A paper sheet cassette 15 is mounted in a copying machine main body. At this time, the projecting body 35 of the paper sheet cassette 15 abuts on the moving body 36 of a paper sheet regulating member 33 corresponding to the paper sheet size so as to rotationally move the moving body, the regulating body 42 of the paper sheet regulating member is projected over a paper sheet guide 17, and energized to the position B to be a projecting posture. When a paper sheet 22 is not delivered in parallel with the transport direction due to dispersion of delivery by a paper feed roller 16 or the like, the paper sheet regulating member 33 is projected from the paper sheet guide 17 so as to regulate the width direction of the paper sheet 22 in parallel with the paper sheet transport direction, and hence the paper sheet is transported without oblique feed by means of the paper sheet regulating member 33.
