Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a wireless mouse of an infrared communication system. For example, when inputting information into a personal computer (personal computer), a pointing device is often used in addition to a keyboard.

In order to operate a personal computer, a pointing device moves a cursor to a specified position on a screen to specify a document or an icon, and includes a mouse, a joystick, a light pen, a touch panel, and the like.

[0003] Among them, a mouse is connected to a personal computer with a cable to input information. However, since the cable is in the way and the operability is poor, a user-friendly wireless mouse without a cable is required. Less mouse)
Is spreading.

However, in this wireless mouse, power must be supplied from a battery mounted in the mouse. Charging is troublesome even when a battery is replaced or a rechargeable battery is used. ing.

The wireless mouse is moved by hand to rotate a ball (see FIG. 5) of the position detecting mechanism, and a data transmitting unit (or a different position from the personal computer) is installed from the data transmitting unit to the personal computer (not shown). (The data receiving unit installed in the PC), the optical movement data by the pulsed light is emitted to perform pointing on the personal computer screen.

[0007] Since the LED generally has a high directivity, if the distance between the data receiving unit and the data transmitting unit is short, the installation range of the data receiving unit cannot be widened. Is arranged so that two or more LEDs are juxtaposed to share the installation range, and the emission direction of infrared light of each LED is fixed.

[0008]

However, according to such a wireless mouse, a considerable amount of electric power is consumed by a plurality of data transmission units (two LEDs and an element driving circuit for driving them). There is a problem that the life of the battery is shortened.

[0009] In view of the above problems, an object of the present invention is to provide a wireless mouse in which the power consumption is reduced as much as possible by using a single data transmission unit.

[0010]

In order to achieve the above object, in a wireless mouse according to the present invention, a communication element for emitting optical movement data is movably fixed to a mouse housing and the communication element is provided. And a device driving circuit for driving the communication device, wherein when the communication device is moved in the mouse housing, the emission direction of the optical movement data is moved and adjusted according to the installation position of the data receiving unit. .

[0011] With this configuration, it is possible to adjust and move the emission direction of the optical movement data of the communication element so as to be directed toward the data receiving section in accordance with the installation position of the data receiving section. The communication element can cover a wide installation range of the data receiving unit, and the data transmitting unit is composed of one communication element and an element driving circuit for driving the same. The power consumption is reduced, and the power consumption of the wireless mouse can be reduced.
