PURPOSE:To reduce a film retrieving mechanism, and to soften generation of a noise and a vibration of a driving system by providing a looseness of a film between a retrieving part, and a feeding part and a winding part of a microfilm, respectively, and executing a scan or a rescan by a movement of a pressure welding member. CONSTITUTION:A high speed feed of a microfilm 2 is stopped, pressure welding glasses 20, 21 are moved to the microfilm 2 side, also the microfilm 2 is inserted and held by holding pads 22, 23 and 24, 25, and thereafter, moved as one body in the horizontal direction, and as a result, the microfilm 2 also moves in the horizontal direction. In accordance with this movement, a frame picture of the microfilm 2 is projected to an optical system 12, and a scan or a rescan of the microfilm 2 is executed by a low speed driving of the pressure welding glasses 20, 21 and the holding pads 22-25. In this case, a looseness 30 and 31 are provided between a retrieving part 10, and a feed reel 1 and a wind reel 4, respectively, therefore, it does not occur that the microfilm 2 is cut or damaged due to an integrated movement of the pressure welding glasses 20, 21 and the holding pads 22-25. |
