Abstract
PURPOSE: To prevent a printing type wheel from being damaged, by detecting reciprocating motion of a printing hammer and executing selection of printing type in accordance with the result of the detection.
CONSTITUTION: When a printing hammer 11 slides in printing motion, a light being applied from a light-emitting element 19 to a light-receiving element 20 is shielded, a motion detecting signal is put out from an AND circuit and defective motion of the printing hammer 11 is detected. On the other hand, the printing hammer 11 returns to its initial position after completing the motion, and then, the light applied from the light-emitting element 19 is again received by the light-receiving element 20, a wait signal from a pulse edge circuit is cancelled, and a printing type selection signal is given from a CPU to a printing type selecting motor 5. The printing type selecting motor 5 turns a printing type wheel 4, so that a printing type 3 is selected. At this time, since motion of the printing hammer 11 is detected and it is competedly kept away from the printing type wheel 4, in no case the printing type wheel 4 is damaged by the printing hammer 11 at the time when the printing type 3 is selected.
