Abstract: An original film holder includes an elongated main body having a plurality of pins for engaging a plurality of punch holes formed in a side portion of an original film; a push-up plate for pushing up the side portion of the original film from the main body to disengage the original film from the pins, the push-up plate being located on the main body and having holes through which the pins are inserted; a pressing member located above the main body and the push-up plate to clamp the original film in cooperation with the push-up plate; a push-up plate moving unit for moving the push-up plate upwardly from the main body to disengage the original film from the pins; a pressing member moving unit for moving the pressing member downwardly to press the original film on the push-up plate; and a retreating unit for retreating the pressing member from a position above the main body.

Abstract: A photosensitive material printing apparatus equipped with a printing portion for printing images of an original film onto a photosensitive material. The photosensitive material printing apparatus is equipped with a holding device for holding the original film at a predetermined position of the printing portion, a moving device for moving the holding device along a photosensitive surface of the photosensitive material, an input board for inputting an amount of movement of the holding device, and a control device for controlling the moving device to move the holding device based on the amount of movement inputted by the input board. Accordingly, the amount of movement of the holding device can be adjusted via the input board.

Abstract: A switch device having a casing, a central terminal and stationary contacts arranged on the bottom wall of the casing, at least one conductor plate swinging at the central terminal as a center for contacting or separating the central terminal with or from the stationary contact, at least one movable contact formed at the conductor plate for contacting with or separating from the stationary contact, and a driver for swinging the conductor plate by tilting at the tilting fulcrum as a center which comprises an edge formed at the upper end of the central terminal, guide grooves extending elevationally at both side walls of the casing oppositely through the central terminal and formed, projections formed at both side edges of the conductor plate to be inserted into the guide grooves, the lower surface of the conductor plate being placed on the edge of the central terminal. Thus, the switch device can be simply assembled with the conductor plates.
