Abstract

PURPOSE: To enable inputs from plural spaces making angles completely different by arranging a path for guiding light while using an optical cable or the like at least in either of a wireless input device or a wireless receiver. CONSTITUTION: A wireless receiver 1 is provided with a receiver side light emitting window 3 for receiving/emitting the light of an optical signal to a wireless input device 2 and equipped with an optical cable 5 arranged in the interior of the wireless receiver 1 so that one terminal side can be opened at one end 1a of the wireless receiver 1 and the other terminal side can be positioned on the front surface of a light receiving/emitting element 4 near the receiver side light emitting window 3. Then, the wireless input device 2 is provided with an input device side light receiving window 6. Therefore, when the wireless input device 2 is fitted onto the wireless receiver 1, optical communication can be performed between the receiver side light emitting window 3 and the light receiving/emitting element 4 and when the wireless input device 2 is detached from the wireless receiver 1, communication is performed by guiding light through the optical cable 5 to the front surface of the light receiving/emitting element 4.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wireless input system used in personal computers, information processing equipment such as word processors, and home game equipment.

[0002]

2. Description of the Related Art In FIG. 3 showing an example of a conventional wireless input system using light, a wireless receiver 31 has a receiver side light receiving / emitting window 33 for receiving and emitting an optical signal with a wireless input device 32. However, in the optical communication, as shown in FIG. 4, the distance and the angle at which the light emitting element 34 on the transmitting side and the light receiving element 35 on the receiving side are formed by the characteristic as shown by the isoluminous curve 36, are communicable. Is decided.

The operator uses the wireless input device 3 shown in FIG.
2 is made to face the light receiving / emitting window 33 on the receiving device side, a distance and an angle for optical communication are secured, and an input operation of the wireless input device 32 is performed.

[0004]

However, in the above conventional wireless input system, the isoluminous curve 3 shown in FIG. 4 is used.
As shown in FIG. 6, the light emitted from the light emitting element 34 becomes weaker as the angle from the front direction increases, and there is an angular range in which the positional relationship between the wireless input device 32 and the wireless receiving device 31 can be communicated. There was a drawback that you could not enter from a space outside the range.

The present invention solves the above-mentioned conventional problems, and an object of the present invention is to provide a wireless input system having excellent operability.

[0006]

In order to achieve the above object, a wireless input system of the present invention comprises a wireless input device and a wireless receiving device for performing wireless communication using light, the wireless input device and the wireless receiving device. An optical cable or a light guide path through which light passes is artificially arranged in at least one of the devices.

[0007]

With the above configuration, a case where the wireless input device is attached to the wireless receiving device by artificially arranging a path for guiding light using an optical cable or the like in at least one of the wireless input device and the wireless receiving device, It is possible to input from a plurality of spaces with completely different angles such as when removed.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A wireless input system according to an embodiment of the present invention will be described below with reference to the drawings.

1A and 1B, the wireless receiver 1 includes a receiver-side light emitting / receiving window 3 for receiving and emitting an optical signal with the wireless input device 2, and the wireless receiver 1 has one end side. An optical cable 5 disposed inside the wireless receiver 1 is provided so that it is opened at one end 1a and the other end is located on the front surface of the light emitting / receiving element 4 in the vicinity of the light receiving / emitting window 3 on the receiver side. The wireless input device 2 includes an input device side light receiving window 6.

The wireless input device 2 is also used as described above.
The optical cable 5 may be provided inside or both the wireless receiving device 1 and the wireless input device 2 may be provided with the optical cable 5.

Further, as shown in FIG. 1B, the wireless input device 2 can be attached to and detached from the wireless receiving device 1, and when the wireless input device 2 is attached to the wireless receiving device 1, the receiving device side reception is performed. Optical communication can be performed between the light emitting window 3 and the light receiving and emitting element 4, and when the wireless input device 2 is removed from the wireless receiving device 1, the optical cable 5
Thus, light is guided to the front surface of the light emitting / receiving element 4 for communication.

That is, by forming a path for guiding light by the optical cable 5 inside the wireless receiver 1,
Optical communication can be performed even when the wireless input device 2 is attached to the wireless receiving device 1 and when the angle at which optical communication is possible is completely different, such as when the wireless input device 2 is removed.

Further, since the block of the light emitting / receiving element 4 may be one set for each of the wireless receiving device 1 and the wireless input device 2, it is cheaper than having a plurality of light emitting / receiving elements 4 to realize the same function. realizable.

Alternatively, as in another embodiment of the present invention shown in FIG. 2, a light guide path 7 through which light passes and a reflecting surface 8 are provided instead of the optical cable 5 to guide the light to the light emitting / receiving element 4. It is possible.

[0015]

As is apparent from the above description, the wireless input system of the present invention includes a wireless input device and a wireless reception device that perform wireless communication using light, and at least the wireless input device and the wireless reception device. On the other hand, by artificially arranging a path through which light is guided using an optical cable or the like, it is possible to input from a plurality of spaces having completely different angles.

Further, since one block of the light emitting / receiving element may be provided for each of the wireless receiving device and the wireless input device, it can be realized at a low cost as compared with having a plurality of light emitting / receiving elements for realizing the same function.
