PURPOSE:To obtain the pen holding device which has less play and does not require fine adjustment, by compressing a pen holder into a hole of the pen holder and supporting it by a supporting shaft that is attached to a slider by using an S-shaped coil so that it is freely rotated. CONSTITUTION:The pen holder 27 is freely rotated with the slider 24 and the supporting shaft 25 as the center. The supporting shaft 25 is attached to one end of the slider 24. The S-shaped coil 32 is coupled into the groove of the supporting shaft 25 by tightening a screw 31, and the supporting shaft 25 is compressed into the one side of the hole of the pen holder 27. Therefore the play between the slider 24 and the pen holder 27 is the play only for the rotation between the pen holder 27 and the supporting shaft 25. |
