Claims

[Scope of Claim for Utility Model Registration] (1) In a drive mechanism that moves a head bank to which a large number of print elements are attached reciprocally and linearly in a predetermined direction substantially perpendicular to the paper feeding direction, between a pair of pulleys disposed at a predetermined position. A print head bank drive mechanism comprising a circulating endless belt, a pin fixedly attached to the belt so as to project substantially perpendicularly from both edges of the belt, and means for connecting both ends of the pin to the head bag. (2) The connecting means includes a first follower that is coupled to the headback and has a groove that engages with one end of the pin and guides the end in a direction substantially perpendicular to the driving direction of the pin. and; having a groove that is integrally formed with the first follower and engages with the other end of the pin and guides the end in a direction substantially perpendicular to the driving direction of the pin; 2. The print head bank drive mechanism according to claim 1, which is a registered utility model and comprises a second off-lower provided with a slit through which the rotation shaft of the pulley passes so as not to come into contact with the rotation shaft of the pulley.
