Conventionally, this type of device, as shown in Figure 1,
It has a structure in which a rubber plate 1 having conductive rubber 2 is placed on a printed wiring board 3, and a contact pattern as shown in FIG. 2 is formed on the printed wiring board 3. When a certain part of 2 is pressed down from above the rubber plate 1, the conductive rubber 2 comes into contact with the contact pattern on the board 3, and the contact pattern 4a,
4b was short-circuited, and this short-circuit was used as input contact information.

あつた。 In this method, the conductive rubber 2 is connected to the contact pattern 4.
Since the structure is in contact with the contact pattern, there is a drawback that the contact pattern must be plated with gold in order to reduce the contact resistance. Furthermore, when the conductive rubber 2 is scraped by the edge of the contact pattern 4 and the fine powder falls onto the contact pattern 4, the contact pattern is short-circuited even when the conductive rubber 2 is not pressed down.

できるようにする提案がない。 On the other hand, an input device has been proposed in which such contact information is obtained from changes in the electromagnetic coupling state between conductors. One example is the signal generator described in Japanese Patent Publication No. 45-6465. However, in this device, there is no proposal regarding the shape of each coil itself and the combination arrangement to make it applicable to a tablet-type input device. The other one is from the 1970s.
This is the switch described in Publication No. 145482 (and microfilm). However, since the two coils in this switch are placed separately in different areas of the printed wiring board, the space for placing the coils becomes large, and it is difficult to increase the electromagnetic coupling between the two coils. If the magnetic permeability member is unbalanced in its proximity, it will not work, and there is no proposal to apply this to a tablet-type input device.
本考案の目的は、小形で安定に動作する電磁形

An object of the present invention is to provide an electromagnetic tablet input device that is small and operates stably.

The present invention forms two spiral patterns at each intersection of two conductor groups by spirally forming the conductors of the first and second groups in parallel and concentrically on one printed wiring board. The high magnetic permeability member facing this is characterized in that it is formed into a sheet shape including a high magnetic permeability member.

An embodiment of the present invention will be explained with reference to FIGS. 3, 4, and 6. In Fig. 3, 6 is a rubber plate having a magnetically permeable elastic body (hereinafter referred to as rubber) 7 containing fine powder with high magnetic permeability such as ferrite, and 9 is a rubber plate having a conductor multiple times at the intersection as shown in Fig. 4. This is a printed wiring board having contact patterns 8a and 8b (contact pattern 8) formed in a spiral shape, and magnetically permeable rubber 7 and contact pattern 8 are arranged to face each other. Note that this contact pattern 8 is insulated to prevent short circuits due to metal powder or dew condensation. As shown in FIG. 6, the contact pattern 8b is connected to the drive circuit 1.
6, the contact pattern 8a is connected to a sense circuit 17, and the drive circuit 16 and sense circuit 17 are controlled by a decoder circuit 18.

とができる。 With the above configuration, the contact pattern 8b is sequentially excited by high frequency by the drive circuit 16.
Push down the rubber plate 6 and move the magnetically permeable rubber 7 to the contact pattern 8
When pressed, the electromagnetic coupling between the contact pattern 8b and the contact pattern 8a becomes tight, and the magnetic flux of the excited contact pattern 8b is transferred to the contact pattern 8a.
There will be more intersections, contact pattern 8
A voltage is generated on a due to electromagnetic induction. This induced voltage is sensed by a sense circuit 17 and sent to a decode circuit 18. Contact information can be obtained in this way.

くい等の効果がある。 According to this embodiment, since the magnetically permeable rubber 7 in contact with the contact pattern 8 has elasticity, it easily fits into the contact pattern 8, provides a good operating feel, and facilitates tighter electromagnetic coupling. Furthermore, the contact pattern is less likely to be damaged.

Further, a magnetically permeable rubber 11 is arranged on the lower side facing the contact pattern 8. When the rubber plate 6 is now pressed down, the magnetically permeable rubber 7, the contact pattern 8, and the lower magnetically permeable rubber 11 come into close contact.

性が非常によくなるという効果がある。 According to this embodiment, when the rubber plate 6 is pressed down, the magnetically permeable rubbers 7 and 11 come into close contact with both surfaces of the contact pattern 8, so that the electromagnetic coupling becomes very tight. Therefore, the voltage induced in the contact pattern 8a becomes large, and the sense circuit 17 is simplified and the noise resistance is very improved.

As described above, according to the present invention, the configuration of the spiral pattern and the high magnetic permeability member is flat, which is convenient for a tablet input device, and the two spiral patterns are arranged concentrically on the same printed wiring board. Because of this, the space for placing the coils becomes smaller, making it possible to make the device more compact, and the electromagnetic coupling between the two coils can be increased, making it stable even if the high permeability members are not close to each other. You can get an effect that works like this.
