る。Referring to FIG. 2, one example of use of the present invention includes an electromagnetically coupled tablet type input device 21, a display device 22,
It includes a light pen 23 according to the invention which can be used both as an input pen for an electromagnetically coupled tablet type input device 21 and as a light pen for a display device 22. An example of the electromagnetically coupled tablet type input device 21 is a pentouch type device such as the "Character Input Device" described in Japanese Patent Application Laid-Open No. 48-43532 filed by the same applicant as the present application. It will be done. When the light pen 23 is used as an input pen for the electromagnetically coupled tablet type input device 21 as shown by the solid line in the figure, the magnetic material or conductor attached to the tip of the light pen 23 is a magnetic material that causes electromagnetic coupling. It plays the role of a substance or a substance that generates eddy currents. In this case, since no light that can be detected by the light pen 23 is generated from the electromagnetically coupled tablet type input device 21, only the input operation of the electromagnetically coupled tablet type input device 21 is performed. When the light pen 23 is used as a light pen for the display device 22 as shown by the broken line in the figure, the magnetic material or conductor attached to the tip of the light pen 23 does not block the light as described above. , the original function of the light pen will not be impaired in any way. As explained above, the light pen according to the present invention is equipped with a light pen for a display device in combination with a magnetic material for electromagnetic coupling or a conductor for generating eddy current. can be shared with Therefore, according to the present invention, it is possible to operate the pen without changing hands between the light pen and the input pen, so it is possible to expect the operation to be extremely simple and to improve the smoothness and reliability of the operation. Although the present invention has been described above with respect to one preferred embodiment thereof, it is needless to say that this is merely an example and does not have a restrictive meaning.

されるが、これら又はその他の変形又は変更はすべて本
願発明の範囲内に包含されるものである。Accordingly, the present invention can be practiced with various modifications without departing from the scope of the invention. For example, in the illustrated embodiment, the magnetic body 12 is formed into a tubular shape, but it is not intended to be limited to this shape, and the cross section may be triangular or square as long as it is a hollow body that guides light. It is clear that the magnetic material may have a hexagonal shape or any other shape, and ferrite is an example of the magnetic material, but it is of course possible to use magnetic materials other than ferrite. Similar considerations can be made when a conductor is used instead of a magnetic material. Although various other modifications can easily be imagined, these and other modifications or changes are all included within the scope of the present invention.
