PROBLEM TO BE SOLVED: To provide a convenient ballpoint pen which has three functions of a ballpoint pen, a pen light, and a touch pen.SOLUTION: A ballpoint pen includes a pen main body 1 and a cap body 2. The pen main body includes an illuminator 31, a storage battery B, and a light transmitting part 32 which transmits illumination light to an external. A touch pen point part 12 is arranged on other end of the pen main body. A first terminal part 51, which is energizably connected to one of a positive electrode and a negative electrode of the storage battery B and has a male screw part 61d, and a second terminal part 52, which is energizably connected to the other of the positive electrode and the negative electrode of the storage battery B, are arranged in a periphery of the touch pen point part. When the cap body covers from an other end side of the pen main body and slides to the one end side, a contact 28 abuts on the first terminal part. When the cap body is rotated in an abutment state, a female screw part 60d of the contact is screwed with the male screw part of the first terminal part. When the cap body is screwed forward, the contact in a screwed state with the first terminal part is made in contact with the second terminal part, and a current flows to light the illuminator.SELECTED DRAWING: Figure 7 |
