を選択する活字選択機構に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a character selection mechanism for type serial printers and typewriters, and in particular to a type body having a large number of characters provided with rotational motion and axial movement to select characters to be printed. This invention relates to a type selection mechanism.

供するものである。However, these mechanisms are complicated and made up of parts that are difficult to machine, making them expensive, and in addition, they cannot be expected to have a long service life due to wear and the like. In addition, since the torque transmission part has a sliding part that cannot be avoided, a gap is required that causes play in the rotation transmission, and this gap causes poor positional accuracy in the rotational direction of the type during printing. was. The present invention solves the above-mentioned drawbacks by directly moving the shaft of the motor for selecting the rotation direction of the fixed typeface in the axial direction. It provides:

本発明の実施例について図面を参照して説明する。According to the present invention, a type selection mechanism is characterized in that it includes a shaft that rotates together with a rotor of a motor, means for moving the shaft in the axial direction together with the rotor, and a type body attached to the shaft. Next, embodiments of the present invention will be described with reference to the drawings.

度で与えられる。The typeface 3 has a blade 15 with typefaces 14 attached in two upper and lower stages.
The motor 1 is configured to be removably attached to a mount 4, and the mount 4 is fixed to the shaft 5 of the motor 1 with a screw or the like. As shown in the cross-sectional view of FIG. It is integrally supported by bearings 8 and 9 and is capable of rotation and axial movement. The step motor 2 has the same structure as the step motor 1, but the shaft 10 only rotates and does not require axial movement. The shaft 10 has an integral cam 11, and the cam 11 has one
At 800 rotations, a displacement equal to the vertical pitch of the letters 14 of the type body 3 is applied. The cam 11 is in contact with a roller 12 provided at the lower end of the shaft 5 to prevent wear.
The spring 13 presses the shaft 5 against the cam 11 appropriately. Here, type selection in the rotational direction of the type body 3 is given by the step division angle by driving the step motor 1.

The rotational movement of the cam 11 caused by the drive of the cam 11 is given by the movement of moving the shaft 5 up and down via the roller 12. When the cam 11 is in the state shown in FIG. 2b, the type body 3 maintains the raised position D (indicated by a solid line) shown in FIG. 2a, and when the cam 11 is in the state shown in FIG. is the lowered position E (
(indicated by the dashed line).

This has the effect of increasing the positional accuracy of.
