A pen-type input device includes a body shaped like a pen; a penpoint movable portion inserted into a front end recess included in the body; and a transmission part which transmits a transcription detecting signal of a contact position when the penpoint movable portion is caused to touch a display face of an electronic information board, wherein the penpoint movable portion includes a penpoint member, which is made of an elastic member and includes a front end portion caused to touch the display face, and a penpoint holding portion, which has a rigidity higher than that of the penpoint member, fits around an outer periphery of a base end portion of the penpoint member, and holds the penpoint member so as to prevent deformation of the outer periphery of the base end portion of the penpoint member. |

1. A pen-type input device comprising:
a body shaped like a pen; a penpoint movable portion inserted into a front end recess included in the body, the penpoint movable portion slidably moving in a longitudinal axial direction of the pen-type input device; and a transmission part which transmits a detecting signal of a contact position when the penpoint movable portion is caused to touch a display face of an electronic information board, wherein the penpoint movable portion includes
a penpoint member, which is made of an elastic member and includes a front end portion caused to touch the display face, the penpoint member being in a tapered shape having a gradient relative to an axis of the penpoint member such that an outer diameter of the penpoint member is smaller on a side of the front end portion than on a side of a base end portion of the penpoint member, anda penpoint holding portion, which has a rigidity higher than that of the penpoint member, fits around an outer periphery of the base end portion of the penpoint member, and holds the penpoint member so as to prevent deformation of the outer periphery of the base end portion of the penpoint member toward the front end recess in a radius direction of the pen-type input device perpendicular to the longitudinal axial direction of the pen-type input device, andwherein the penpoint holding portion of the penpoint movable portion protrudes, both at a time when the pen-type input device is used to write and a time when the pen-type input device is in a storage state, from the front end recess included in the body on a side of the front end portion of the penpoint movable portion in the longitudinal axial direction of the pen-type input device, and intervenes, both at the time when the pen-type input device is used to write and the time when the pen-type input device is in the storage state, between the front end recess and the penpoint member in the radius direction of the pen-type input device to prevent contact between the front end recess and the penpoint member. |
