A carriage lock mechanism is provided with a lock member mounted on a movable member of the carriage mechanism, a lock pawl for engaging with the lock member to lock the carriage mechanism, and a spring for biasing the lock pawl in a direction where the lock pawl engages with the lock member, wherein a sliding surface on which the distal end of the lock pawl slides during the lock operation is formed on the lock member, and the sliding surface has a shape corresponding to a locus of the lock member. If the movable member of the carriage mechanism is to be pivoted about a shaft, the sliding surface consists of an arc surface having the shaft as its center.
