もので構成しているが片側だけでもよい。 In the above configuration, the light pen body 11
is pushed in the direction of arrow A and the tip of the switch sliding member 3 comes into contact with the transparent plate 13, and as the light pen body 11 moves in the direction of arrow A thereafter, the switch sliding member 3 moves in the direction of arrow A. It is in a state where it is pushed in the opposite direction, and due to this movement of the sliding member 3,
As shown in FIG. 4, the switch plate 4 which has been open until now is pushed in by the switch sliding member 3, and the opening portion of the switch plate 4 is displaced in the direction of closing, and at a certain point as shown in FIG. It becomes closed.
In this example, the switch plates 4 are constructed of a pair of left and right switch plates, but only one switch plate may be used.

単で製作が容易である。 As described above, according to the present invention, the movement of the sliding member is optically detected when the pen is pressed, and the signal light is detected by the light receiving element. In a light pen device comprising a photoelectric switch consisting of light emitting and light receiving elements, the light emitting element and light receiving element for the switch are arranged side by side in the longitudinal direction of the device.
It becomes possible to reduce the outer diameter of the light pen device, and as a result, the operability of the light pen is improved and the design is also improved. Further, since there is no need to use expensive parts such as fibers and the structure is simple, assembly is easy and difficult adjustments are not required. Therefore, it has various advantages such as being able to provide a light pen device at low cost. Furthermore, according to the present invention, opening and closing of the optical path between the light emitting and light receiving elements of the photoelectric switch is performed by a switch plate, and the switch plate is provided at a position protruding from the end of the sliding member. Before the sliding member moves, the sliding member is in a state where it is opened wider outward from the end opening of the sliding member, and when the sliding member is moved, the member is pushed into a surrounding part that surrounds the sliding member and becomes a closed state. Therefore, the structure is simple and manufacturing is easy.
