PURPOSE:To eliminate the need for a separate scanning drive system, by making rotation and scanning for the original loading stand exclusively with a rotating driving system. CONSTITUTION:A scanning driving system is excluded and a stopper arm 18 latched with a linking tab 16 of a wire of a scanning plate 4 and a solenoid 20 engaging and disengaging with the said arm and the tab are provided instead. An electromagnetic clutch between a rotating motor 13 and a pulley 12 is excluded. Further, static friction coefficient between a scanning plate 4 and a rotating plate 6 is selected to become larger than that between the scanning plate 4 and a guide bar. The solenoid 20 and the stopper arm 18 are respectively provided for two tabs 16, 16, allowing to block the movement of the scanning plate 4 through the arm 18 coupled with the tab 16. |
