Abstract

A touch pen of a pen-type electronic input device includes a shaft-shaped body, a pen tip used to input information and provided on a front end of the body, a switch unit used to perform operations and arranged in a line on a side face of the body, and an electrically conductive barrel in which a slit is formed in an axial direction, wherein the switch unit passes through the slit to be mounted on an outer face of the body in an exposed state.

First claim

What is claimed is:

1 . A touch pen of a pen-type electronic input device comprising:
a shaft-shaped body; a pen tip used to input information and provided on a front end of the body; a switch unit used to perform operations and arranged in a line on a side face of the body; and an electrically conductive barrel in which a slit is formed in an axial direction, wherein the switch unit passes through the slit to be mounted on an outer face of the body in an exposed state.

2 . The touch pen according to claim 1 , further comprising:
a conducting unit, provided inside the body, that conducts electricity from the pen tip to the barrel, wherein in a case of using the touch pen with a capacitive touch panel, an electrostatic capacitance of the pen tip is secured by having a user hold the barrel.

3 . The touch pen according to claim 1 , wherein
the barrel is metal.

4 . The touch pen according to claim 1 , further comprising:
a battery provided inside a housing of the body in a central part in the axial direction of the body.

5 . The touch pen according to claim 1 , wherein
the barrel is formed in a shape in which a front end part is cut diagonally.

6 . A display device comprising:
a touch panel that receives handwriting input; a display unit that displays a trail of handwriting received by the touch panel; and an operating member that performs an input operation with respect to the touch panel, wherein the touch pen according to claim 1 is used as the operating member.
