Abstract
An arrangement for scanning a disc-shaped type carrier in a code controlled printing device has a stepping motor which is controllable in the forward and backward directions for setting the type carrier. The count of a ring counter contained in the stepping motor control, and which is set in accordance with the setting of the stepping motor, is compared, as a binary combination, in a comparator device with a binary combination assigned to a specific character, and in the event of parity of the two binary combinations, an output pulse is emitted. A scanning sector is arranged on the type carrier and extends over a plurality of characters including the specific character, preferably centrally located along the scanning sector. A scanning device produces a scanning pulse in response to rotation of the sector to or past the scanning device and the scanning pulse is conjunctively linked with the output pulse of the comparator for utilization in system synchronization.
