PURPOSE: To enable the input member tip end of an input pen to be prevented from being scratched by permitting a synthetic resin pipe force fitted in the front projection part of a press member to be bent relative to the press member at the time of driving an input pen forward. CONSTITUTION: In a state of an input pen 6 and ball-point pen 7 retracted, when the knocking part of a press member 4 coupled with the input pen 6 is pressed forward in the longitudinal direction, the press member 4 advances in the sliding groove 2A. Then, a spherical part 4D of the press member and synthetic resin pipe 6B of the input pen 6 are caused to bend so that the input pen 6 Is Introduced in the inner surface of a front shaft 1 and projects from the tip end opening hole 1A smoothly. As the press member further advances, an inclined step 4B engages with the front end 2C of an engaging projection part 2B of a rear shaft 2. In this manner, the press member 4 is urged in the direction of the central axis to then be engaged positively. Thus, even when an input operation is conducted by forcibly pressing the tip end of the input pen, the press member 4 does not fail to engage therewith. |
