[Technical field to which the invention belongs]

 The present invention relates to a type of optical index sensing device, and more particularly, to an optical index sensing device which is used for an index or cursor movement sensitive control in electronic equipment or a computer, and which can be used in both forward and reverse directions.

[0002]

[Prior art]

 Indices or cursors are widely used in various computer and electronic equipment and are used as screen windows, selection and key-on components. Well-known indicator control equipment is a mouse, joystick, trackball, and touch panel. Among the control equipment for these indicators, the mouse, joystick, trackball, and touch panel require mechanical frictional movement or pressure contact, thereby picking up the indicator signal. Such mechanical frictional movement or pressure contact has a problem in that it becomes caught irregularly or difficult to operate in use.

[0003] Also, the known detection method requires complicated mechanical-optical-electrical three-dimensional physical condition sensitivity and level conversion. For example, in the case of a mouse or a trackball, the capstan is rotated by mechanical movement of the ball. The optical signal generated by the capstan is picked up and converted into an electric signal. Such a complex indicator sensitivity and signal pickup method increased the manufacturing cost of the product, was inconvenient to operate, and was very liable to cause failure, damage and reduced sensitivity of sensitive components.

[0006] Yet another object of the present invention is to provide a kind of optical index sensing device, which provides an optical sensing signal directly to an electronic equipment or a computer by an optical detecting element to control the index or cursor control. As a basis, signal layer-by-layer conversion is not required, and product cost can be reduced and the sensitivity of indicators or cursor control can be increased.

The groove 11 is provided in the main body 10 described above, and at least one optical detection element 20 is embedded in the groove 11, and a lens 21 is provided in front of the optical detection element 20. Can transmit and receive an optical signal through the lens 21, and can generate an electric signal corresponding to the moving image. The translucent contact plate 30 is fitted into the upper part of the groove 11, and a distance A is formed between the translucent contact plate 30 and the lens 21 of the optical detection element 20, and the distance A is the optical focal length of the lens 21. When the finger (see FIG. 3) or a pen, a needle, or another pointing object makes contact with the surface of the light-transmitting contact plate 30 to perform a moving operation in a different direction, the optical detecting element 20 causes an electric signal corresponding to the moving image to be obtained. The information is obtained and given to an electronic device or a computer (not shown) to be a basis for a display index or a cursor movement control.

In addition, the above-mentioned distance A is the focal length of the lens 21 of the optical detection element 20 and is located above the light transmitting contact plate 30, but other objects or images on the surface of the light transmitting contact plate 30. , The image is accurately formed in the optical detection element 20 outside the focal length of the lens 21, and the optical detection element 20 does not generate a corresponding moving image electric signal. Noise can be eliminated.

FIGS. 1 to 3 show a state of being fitted in the groove 11 and moving by directly touching the surface of the light transmitting contact plate 30 with a finger or a pointing object. When the operation is performed, the optical detection element 20 emits a signal with the upward direction of the positive direction, and acquires the corresponding electric signal of the moving image by a method of reflecting the signal downward.

Conversely, as shown in FIG. 4, when the light-transmitting contact plate 30 is removed from the groove 11, the main body 10 is inverted in the opposite direction and placed on the planar object 200 according to the detection result of the sensor 40. The optical detection element 20 emits a signal in a downward direction in the opposite direction and obtains an electric signal corresponding to the image fluctuation in a manner of reflecting the signal upward, and the electronic equipment is similarly operated.

The light transmitting contact plate 30 ′ is provided in at least one end of the channel 12, and the light transmitting contact plate 30 ′ is installed in the channel 12. The finger or other pointing object moves in contact with the surface of the translucent contact plate 30 ', and the optical detection element 20 generates an index or an electric signal for cursor movement control. Similarly, after the translucent contact plate 30 ′ is extracted from the channel 12, the main body 10 is inverted and moved on the plane object 200, so that the index or the cursor can be controlled.

FIG. 6 shows a third embodiment of the optical index sensing device 100 of the present invention. When the blind spot is different from the second embodiment of FIG. A pair of elastic means 32 'is embedded between the bottom of the convex key 31' and the lower part of the light transmitting contact plate 30 ', and is automatically restored to the original position after the convex key 31' is opened. Provide the function to do. However, when the convex key 31 'is pressed down and is aligned with the surface of the translucent contact plate 30', the distance between the lens 21 of the optical detecting element 20 and the bottom of the convex key 31 'and the lens 21 is reduced, and the optical detecting element is reduced. 20. At this time, the focal length is the length of the image formed by the lens 21.
