    • An apparatus for conveying photosensitive material includes a core for holding a roll of photosensitive material in a paper magazine, drive rollers disposed in a conveyance path of the photosensitive material, two sets of nip rollers disposed to oppose the drive rollers at upstream and downstream locations relative to the forward direction of photosensitive material conveyance, rewind nip rollers disposed to oppose the upstream set of nip rollers, and a controller for controlling the drive rollers. When the photosensitive material is wound back into the paper magazine after use, the control means causes the drive rollers to rotate in reverse until the leading end portion of the photosensitive material is located between the upstream nip rollers and the rewind nip rollers. This enables the leading end portion of the photosensitive material to be held straight (without bowing), thereby protecting it from curling.
    • 用于输送感光材料的设备包括用于将感光材料卷保持在纸盒中的芯,设置在感光材料的输送路径中的驱动辊,设置成相对于驱动辊在上游和下游位置处相对的两组夹持辊 感光材料传送的前进方向,与上游组夹辊相对配置的倒带夹持辊以及用于控制驱动辊的控制器。 当感光材料在使用后被卷回到纸盒中时,控制装置使得驱动辊反转旋转,直到感光材料的前端部分位于上游夹持辊和倒带夹持辊之间。 这使得感光材料的前端部分保持直线(不弯曲),从而防止其卷曲。

    • A screen printing apparatus includes: a positioning stage for positioning an object and a plate arranged above it; printing squeegees which are moved horizontally on the plate for printing through the plate onto the object; a driver for moving the positioning stage; a horizontal driver for moving the positioning stage in two substantially perpendicular directions; a positioning controller for calculating a central position of a pattern on the plate from a reference position and the size of an outer periphery of the object, moving the positioning stage so that the central position corresponds to a center of the object. A carry-in conveyor is provided for feeding the object onto the positioning stage along a predetermined transferring direction, the conveyor being arranged away from the positioning stage and having a carry-in conveyor surface on which the object is placed before the object is fed onto the positioning stage. The carry-in conveyor surface is positioned within the same plane as an object placing surface of the positioning stage. A carry-out conveyor is provided for transferring the object on the positioning stage along the transferring direction, the carry-out conveyor being arranged away from the positioning stage and having a carry-out conveyor surface on which the object is placed after the object is fed from the positioning stage. The carry-out conveyor surface is positioned within the same plane as the object placing surface of the positioning stage.
