ABSTRACT:
A printer having a switch gear, first driven gear and second driven gear. The switch gear has a spur gear and is slidable along a direction that is parallel to a rotation axis of the spur gear. The first driven gear has a first spur gear and a cylinder fixed to the first spur gear. The cylinder is concentric with respect to the first spur gear and extends along the above direction. A hole is formed on the second driven gear. The hole is concentric with respect to a second spur gear and extends along the above direction. The second driven gear is rotatably mounted on the first driven gear by inserting the cylinder of the first driven gear into the hole of the second driven gear. The switch gear slides between a first position for engagement with the first driven gear and a second position for engagement with the second driven gear along the above direction. Since the driven gears are formed in this way, the position of the first driven gear in the above direction is not changed even when the second driven gear is not provided.
