Abstract
A printer having a spring-loaded print head which can be pressed against a counterpressure roller, wherein an active strand of a printing ribbon and a medium to be printed run between the print head and the counterpressure roller, can be configured such that the printing ribbon is unwound from a first spool and is wound up on a second spool, can preferably have a slip clutch disposed between the drive of the second spool and the second spool and/or between a drive and a drive roller in contact with the medium to be printed, and the slip clutch can be disposed in a wheel with a concentric shaft. Between the shaft and the wheel there can be at least one pair of axially spring-loaded friction discs. As an advantageous connection, the invention teaches that the wheel can be designed as an openable hollow body, that all the elements of the slip clutch are located inside the wheel, and that the shaft can be inserted into the slip clutch, whereby the at least one shaft-side friction disc can be connected to the shaft in an interlocking manner.
