ABSTRACT:
A printer comprises printing means; a carriage on which this printing means is mounted; an endless, loop-like timing belt, fixed to the carriage, for moving the carriage, the surfaces of this endless belt which face with each other having serrated toothed portions; and a member for sandwiching the endless belt to stop the movement of the carriage. This printer may be also provided with an intermediate engaging member which is interposed between the upper and lower belts of the endless belt. This engaging member has serrated toothed portions having the same pitch as that of the serrated toothed portions of the endless belt. With this simple constitution, the carriage can be easily locked and unlocked without using special tools such as a screw and a screwdriver.
