Abstract: PROBLEM TO BE SOLVED: To realize simplification and miniaturization of a structure and smoothly transfer printing papers by utilizing a slack side of a transfer belt for transferring printing papers. SOLUTION: A driving system is provided, in which a driven pulley 109 at the downstream side of the transfer belt 30 is driven in an up-down direction to rotate with a main pulley 108 at the upstream side being made a rotation center, thereby facilitating securing of an opening/shutting movement path of a head cap for opening/shutting a head face of a head cartridge 8. A pinch roller 29 is adapted to suppress the behavior by slack on an upper path 30a which is the slack side of the transfer belt 30, at a near position at the upstream side of the head cartridge 8.

Abstract: PROBLEM TO BE SOLVED: To easily remove a photographic paper sheet, when jammed, by separating a carrying roller from a power transmission system. SOLUTION: This photographic paper carrying device comprises a gear train 30 for transmitting the driving force of driving force supply means to the carrying roller 13 carrying the photographic paper sheet and an arm part 22 for rotatably supporting gears 31-33 of the gear train 30. When the driving force is supplied by the driving force supply means, the gear train 30 engages a carrying roller gear 20 to permit the rotation of the carrying roller 13, and when torque for rotating the carrying roller 13 becomes given force or more with the occurrence of jam, the arm part 22 is supported so as to be moved in the direction of separating an end gear 33 of the gear train 30 from the carrying roller gear 20.
