PURPOSE:To attain miniaturization and thin profile by adopting a structure where the movement of a carriage is guided by the flange of a pulley provided to a pulse motor and one guide bar to use only one guide bar. CONSTITUTION:A pulse motor 8 is positioned to the lower side and a pulley 9 is positioned to the upper side. A flange 9a is provided incorporatedly with the pulley 9 and the flange 9a is fitted to a guide groove 1a of the carriage 1. The guide bar 2 has a construction provided only with one bar at the opposite side of the flange 9a. A steel belt 10 is wound or unwound by the turning of a pulse motor 8 and guided stably with the flange 9a and the guide bar 2 when the carriage 1 is slided, then the sliding accuracy is held surely only with on guide bar 2. |
