Abstract
Printing apparatus for electric office machines a print unit having a motor (14) and a disk-shaped type element (17) connectable with the motor shaft (16). The print unit is pivotably mounted for movement between a printing position, in which the type element is fixed for movement with the motor shaft, and an upwardly pivoted position in which the type element is disengaged from the motor shaft to allow replacement. A locking system permits upward pivoting of the print unit only when the type element has assumed a predetermined angle. The locking system comprises a lock collar (23) rigidly connected to the motor shaft (16) and having an end wall in which there are at least two axially directed recesses (24), or alternatively having at least two axially directed pins, the recesses or pins coacting with complementary parts (39) arranged on a disengagement systems (33, 34, 36, 37), axially displaceable during the pivoting movement.
