Abstract

PURPOSE: To obtain a small, lightweight and robust original platen by disposing a turning means to a direct moving guide means and main unit side or disposing the turning means between the moving body which supports glass plate or the like and the main unit.
CONSTITUTION: The supporting body 56 of a direct moving guide means is mounted to the wall 55 of an original platen 51 to support both ends of a circular columnar rail 57. A moving body 58 which supports a glass plate 52, cover 53, etc. is supported to the rail 57 by way of drum type rollers 59a, 59b. Hence, when the moving body 58 is driven by means of a wire 61, its raised parts 58a, 58b are engaged to the rollers 59a, 59b and are thereby guided, making reciprocating movement in the axial direction of the rail 57. When the rollers 59a, 59b, retainer 60 and moving body 58 are integrally turned about the rail 57, the original platen 51 may be raised. Since in this way the reciprocating movement for scanning of the original base and turning motion for the purpose of maintenance are accomplished by the single member, the original platen may be made to the small, lightweight and robust construction.
