Printing Device

This printer is suitable for printing leaf-shaped record carriers, such as badges 1.

A hammer unit 6 is mounted in type carrier unit 5 that is arranged between two plates 3, 4, spaced from each other by spacer block 2.

Type carrier unit 5 has two endless toothed belts 7, 8 which are guided over one pair of toothed disks 9a, 10a and 9b, 10b, respectively. One disk each of the two pairs of toothed disks (10a, 10b) is rigidly fixed to driving shaft 11 which is operated by an electric motor, not shown. Toothed disks 9a, 9b of the two disk pairs are supported on shaft 12. Driving shaft 11 is positioned in bearings 13 which are permanently fixed to the two plates 3, 4, whereas the other shaft 12 protrudes into a bearing blocks 14 which is arranged to be shiftable in each plate 3, 4. Each of these bearing blocks is guided in a slot 15 of plate 3 or 4, whose longitudinal axis is positioned on the straight line intersecting the center line of shafts 11, 12. Each bearing block 14 has two slots disposed parallel to the longitudinal axis of the slots and through which screws 16 protrude, which are screwed into plate 3 and 4, respectively.

Toothed belts 7,8 are made of rubber, accommodating leaf springs 17 which have readily releasable positive connections on their outer ends. The positive connection consists in the leaf springs being provided on each end with a U- shaped hook, which protrudes into the one tooth spacing of belts 7 and 8, respectively. Thus, le...
