Abstract
The present invention provides an apparatus having a carriage, in which, even when a toothed belt having a fine tooth pitch and low tooth height is used to drive the carriage, a jumping phenomenon of the toothed belt is positively prevented to thereby achieve stable scanning of the carriage without requiring a driving motor having a large capacity and an additional carriage position detecting device. A member for preventing the jumping of the toothed belt is disposed to create a predetermined gap with respect to a back surface of the toothed belt and is inclined with respect to the back surface by a predetermined angle at a position where the member is opposed to the back surface of a portion of the toothed belt to which the carriage is connected, in the vicinity of the driving pulley for the toothed belt connected to the carriage on which a head is mounted.
