Abstract

A device is provided for guiding a print element of a printer device. The guide device comprises a guide bushing which is provided with two sliding surfaces and which is carried on a guide rail facing the platen. A support mount is engaged over the guide bushing and has a projection for fastening a traction device, such as a toothed belt, of a drive system. The support mount also has latch openings for receiving latch pieces for accurate positioning of the print element. The print element further comprises a fork-like guide projection to be received over and for sliding along a second guide rail. In order to fasten the print element to the guide bushing, a resilient snap-in clip is held constantly locked at the print element, the snap-in clip being pivotal so as to partially embrace the guide bushing and has projecting ends which are freely accessible for unlatching of the clip.
