PURPOSE: To use a paper money recognition part both for a money dispensation processing and for a money reception processing.

CONSTITUTION: In the case of the money reception processing, a driving motor 1 is turned forward an when a driving gear 2c is turned through a driving belt 3, the driving gear 2c applies driving force through a reception gear 5 to rollers 5a and 5b and a conveyer belt mechanism 6 and conveys a medium in a direction A. When moving from the money reception processing to the money dispensation processing, a plate 2 is attracted by electrifying a solenoid 14, and linkage between a driving gear 2c and a driven gear 5 is disconnected. Next, when a motor 11 turns a pedestal 4 around a core 4a by a transmitting belt 12 and it is detected that the pedestal 4 is turned at 180° by a photointerrupter 13 and a projecting part 4b of the pedestal 4, turning is stopped. Afterwards, when electrification to the solenoid 14 is cut off, the driving gear 2c and the driven gear 9 are engaged each other and therefore, when the driving motor 1 is turned backward, paper moneys are conveyed in a direction B.
