Claims

[Scope of utility model registration request]

A large ring part in which printed letters are arranged on the circumferential surface at a constant angular pitch and a small ring part having selection grooves arranged in the same number on the circumferential surface in correspondence with the printed letters at the same angular pitch as the above-mentioned angular pitch are integrated. A plate-shaped selection having a type wheel which is controlled to rotate or stop, and a stopper on one end that engages and disengages from the selection groove, and a drive end on the opposite side of the stopper, and is pivoted on a fixed pivot. A spring that biases the selection pawl so that the stopper comes into elastic contact with the circumferential surface of the small ring part, and a pull rod part that is disposed behind the drive end part and has a restraining flange at the tip. , a plunger-type solenoid whose pull rod portion moves in the longitudinal direction of the selection pawl and releases the selection pawl into a pivotable state when type is selected; a selection claw arm and a restraint for locking or releasing the drive end at the non-pivot end of the relay link; A type selection device for a printer that forms a solenoid side branch that is pulled and operated by a flange.
