Abstract

PURPOSE: To omit a separate detector, and to simplify and miniaturize the device by detecting as to whether or not the type ring is under a set condition by utilizing signals used for selecting the type of the impact printer.
CONSTITUTION: When a type ring driving motor 11 is turned and the selection of the type of the type ring 4 is completed in an electronic numbering drvice, a projection of a cam 37 formed to one part of a main gear group 25 pushes a contact of a switch 38, and β signal (b) are generated. Accordingly, the type ring driving motor 11 is stopped under control. Here, when a printing command is issued by operating a printing switch (c), a motor 17 functions and the type is printed by means of a cam mechanism, but the time when the printing switch is pushed effectively can be specified to when β signal (b) are at on, when the type ring 4 is under the set condition, because β signal (b) is inputted to an AND circuit for the motor 17 for pushing down the type ring.
