Claims

[Scope of utility model registration request]

An input pen that operates a switch placed behind the core by pressing an exchangeable core such as a ballpoint pen supported at the tip of the pen shaft so as to be movable in the axial direction toward the inside of the pen shaft. In,
A magnetic piece is provided at the rear end of the core, or the rear end of the core is made of a magnetic material, and has a through hole that is magnetized in the axial direction and can slidably accommodate the core. An input pen characterized in that a bar magnet is provided near the tip of a pen shaft, a spring is interposed between the core and the switch, and at least one end of the spring on the core side is made of a magnetic material.
