[Industrial applications]

 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a trackball device, and more particularly to a novel improvement for illuminating a ball so that the ball can be used even in a dark place.

[0002]

[Prior art]

 As a trackball device of this type that has been conventionally used, the configuration shown in FIG. 3 is generally adopted. That is, as a trackball device called a mouse of this type which has been conventionally used in an OA or a computer, a biaxial mouse shown in FIG. 3 is generally representative. That is, a ball 2 having a part exposed downward through a bottom plate 1a of a casing 1 having a shape like a tortoise shell is rotatably provided, and the outer circumference of the ball 2 has different X-directions. A pair of rotating shafts 3 and 4 are rotatably provided in the Y direction and the Y direction via bearings 3a and 4a.

Rotation detecting plates 5 and 6 are provided on the rotary shafts 3 and 4, respectively, and the rotations of the rotation detecting plates 5 and 6 are detected by the first and second detectors 7 and 8. It is configured.

Therefore, in the above-mentioned configuration, by grasping the casing 1 with the hand and running the ball 2 on the input medium such as a map or a picture, each of the detectors 7 and 8 operates in response to the rotation of the ball 2. The obtained signal is read by a computer or the like as an input signal.

[0005]

[Problems to be solved by the device]

 The conventional trackball device has the following problems because it is configured as described above. That is, since the ball itself is not self-luminous, it could not be confirmed in the dark, which was extremely inconvenient.

The present invention has been made to solve the above problems, and it is an object of the present invention to provide a trackball device that can be used even at night by illuminating the ball.

[0007]

[Means for Solving the Problems]

 The trackball device according to the present invention is a trackball device configured to output a predetermined number of pulses by rotating a ball, and a transparent ring body fixedly arranged at an outer peripheral position of the ball and the ring body are irradiated. And a light-emitting body for operating.

[0008]

[Action]

 In the trackball device according to the present invention, by illuminating the transparent ring body provided on the outer peripheral position of the ball with the light emitter, the ball can be illuminated through this ring body, and the ball can be illuminated even in a dark place. The location can be easily found.

[0009]

【Example】

 Hereinafter, preferred embodiments of a trackball device according to the present invention will be described in detail with reference to the drawings. It should be noted that the same or like parts as those of the conventional example are designated by the same reference numerals and described. A reference numeral 1 in FIGS. 1 and 2 is a casing, and a transparent ring body 11 is fixedly provided in an opening 10 formed in an upper portion of the casing 1.

A ball 2 is rotatably provided in the ring body 11, and the ball 2 is configured to obtain an output pulse by rotation like the structure of FIG. 3, but it is omitted in FIG. ing.

A light-emitting body 13 such as an LED is provided on the inner wall 1b of the casing 1 via a handle 12, and the light-emitting body 13 is configured so that it can be arbitrarily turned on via a switch and a power source (not shown). There is.

Therefore, in the above-described configuration, the ball 2 is irradiated by the light emitting body 12 by lighting the light emitting body 12 through the switch in a dark place. When the ball 2 is rotated and an output pulse is generated, the light emitting body 13 can be turned off through an electronic switch circuit (not shown).

[0013]

[Effect of device]

 Since the trackball device according to the present invention is configured as described above, the following effects can be obtained. That is, the ball can be illuminated by irradiating the ring body located on the outer periphery of the ball, and the ball can be easily confirmed even in the dark part, and the function of the trackball device can be improved.
