Claims

[Scope of utility model registration request]

(1) A type carrier having a large number of type characters, such as a type belt or a type wheel, and a code plate that rotates in synchronization with the type carrier;
The code plate is equipped with a sensor plate which is gear-coupled, and the code plate has 9 contact points and a predetermined number of code plate reference position signals in one rotation to generate a signal corresponding to a hot type character in one rotation of the code plate. The sensor plate is provided with a contact portion for generating a predetermined number of sensor plate reference position signals in one rotation of the sensor plate, and the code plate reference position signal and the sensor plate reference position signal are 1. A type position detection device for a printer, characterized in that a gate means is provided for generating a type reference position detection signal only when the two occur simultaneously.

(2) The code plate base position signal generated by one rotation of the code plate and the sensor plate reference position signal generated by one rotation of the sensor plate are both single, and the period when the code plate reference position signal is generated once is A common multiple of the number of type corresponding signals and the number of type corresponding signals during one generation of the sensor plate reference position signal is set equal to the number of the set of type on the type carrier. Claims for Utility Model Registration: A type position detection device for a printer as set forth in item (1).

(3) The detection range of the sensor plate reference position signal is as follows. The printing type position detection device for a printer according to claim 1, wherein the width of the gear connection between the code plate and the sensor plate is wide enough to allow a rotational transmission error. □
