字選択機構。 A plurality of drive sleeves made of magnetic material are fitted at predetermined intervals on the outer periphery of a selection shaft rotationally driven by a drive motor, and electromagnetic coils are loosely fitted on the outer periphery of each of these drive sleeves. A pair of type selection plates made of a magnetic material are arranged on both sides of the sleeve in the axial direction, and the plate is rotated by energizing the electromagnetic coil to attract the plate to the drive sleeve. In a type selection mechanism of a microprinter that selects a desired type on a type wheel, holding openings for holding the drive sleeve and a pair of plates are formed at equal intervals near the selection shaft, and the rotational movement of the plates is formed in the vicinity of the selection shaft. A type selection mechanism for a microprinter, characterized in that a plate holder made of a non-magnetic material and having a cross-sectional shape for guiding the type is provided.
