With the recent miniaturization of personal computers, there has been a demand for miniaturization of pointing devices. However, as described above, since the circuit board built into the mouse was provided with a plurality of DIP switches for switching the transmission channels, the presence of the DIP switch was an obstacle to the miniaturization of the mouse. Realization was difficult.

An object of the present invention is to provide the function of the DIP switch also in the click button for confirmation,
We realized space saving of circuit board built in mouse,
As a result, it is to provide a radio-type wireless mouse capable of downsizing the mouse body.

[0006]

According to the present invention, a click button, a transmitter for transmitting a positioning signal to a receiving side, and a transmitter for using an optimum transmission frequency for transmitting the positioning signal. In a radio type wireless mouse equipped with a frequency synthesizer for setting a channel, when the click button is turned on after the radio type wireless mouse is turned on, the first transmission channel is selected and the click button is clicked. When turned off, a radio-type wireless mouse is obtained which has a discrimination circuit for selecting the second transmission channel and transmitting the selection signal to the frequency synthesizer.

Further, according to the present invention, the first and second click buttons, the transmitting section for transmitting the positioning signal to the receiving side, and the optimum transmission frequency for transmitting the positioning signal are used. In a radio-type wireless mouse equipped with a frequency synthesizer for setting a transmission channel, if both the first and second click buttons are turned off after the radio-type wireless mouse is turned on, When the transmission channel is selected and both the first and second click buttons are turned on, the second
When the first click button is turned off and the second click button is turned on, the third transmission channel is selected, and the first click button is turned on. When the second click button is turned off, the radio transmission type wireless mouse is obtained which has a discrimination circuit for selecting the fourth transmission channel and transmitting the selection signal to the frequency synthesizer. .

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a block diagram showing the configuration of a radio-type wireless mouse according to the present invention. FIG. 2 is a diagram showing transmission / reception between the radio-type wireless mouse and the receiving side. In FIG. 1, the radio-type wireless mouse 10 is
The power supply 4, the left and right click buttons 6 and 7, the transmitting antenna 1, and the transmitting unit 2 that transmits the positioning signal to the receiving side.
And a frequency synthesizer 3 for setting a transmission channel for using an optimum transmission frequency for transmitting the positioning signal, and rotation of the rotary ball 8 is decomposed into X-axis and Y-axis directions, and an increment value thereof is calculated. It is composed of a discriminator 15 which detects and specifies the position on the display screen by confirmation signals from the left and right confirmation click buttons 6 and 7. Here, switching of the transmission channel is performed by using the click buttons 6 and 7 for confirmation.

Now, how the transmission channels are switched using the confirmation click buttons 6 and 7 will be described with reference to the drawings. FIG. 3 is a flow chart for explaining one embodiment of the operation of the radio wave type wireless mouse discriminator 15 of the present invention, and FIG. 4 is another embodiment of the operation of the radio wave type wireless mouse discriminator 15 of the present invention. 4 is a flowchart for explaining

A first embodiment of the transmission channel switching method will be described with reference to FIG. Here, in the first embodiment, the transmission channel is set to the two channels of the first channel and the second channel, and only one left or right click button is used for switching the transmission channel. . In FIG. 3, first, the power supply 4 of the mouse body is turned on (step S101). next,
The discriminator 5, which has confirmed that the power is turned on, determines whether the left or right click button is on or off (step S10).
2). If it is on, the first channel is used as the transmission channel (step S103). If it is off, the second channel is used as the transmission channel (step S104). After this, the operation returns to normal (step S105).

Next, a second embodiment of the transmission channel switching method will be described with reference to FIG. Where the second
In this embodiment, the transmission channels are set to four channels, that is, the first channel to the fourth channel, and the click buttons used for switching the transmission channels are both left and right. In FIG. 4, first, the power supply 4 of the mouse body is turned on (step S201). Next, the discriminator 5, which has confirmed the power-on, determines whether the right click button 7 is on or off (step S202), and when it is on, determines whether the left click button 6 is on or off (step S202). S203). If it is turned on, the second channel is used as the transmission channel (step S20).
5) If it is off, the fourth channel is used as the transmission channel (step S206). If the determination in the previous step S202 is off, it is determined whether the left click button 6 is on or off (step S20).
4). Here, when it is on, the third channel is used as the transmission channel (step S207), and when it is off, the first channel is used as the transmission channel (step S208). After this, the normal operation is returned (step S209).

The discriminator 5 sends the information of the transmission channel determined in this way to the frequency synthesizer 3 as a selection signal, and the frequency synthesizer 3 sets the frequency corresponding to the transmission channel based on the selection signal. It is sent to the transmitter 2. The transmitter 2 modulates the confirmation signal from the discriminator 5 with the frequency. The modulated signal is transmitted to the receiving unit 12 via the transmitting antenna 1 and the receiving antenna 11 of the receiving-side personal computer 13 as shown in FIG.

Although the present invention has been described with respect to a mechanical wireless mouse, it can be similarly applied to an optical wireless mouse.
