Description

Mouse with X, Y axis and scroll key controllable by using 2 photo diodes}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mouse. In particular, a mouse receiving light reflected on stripes formed on a cylindrical surface and receiving light reflected from the surface to measure movement of the mouse receives light reflected from the X and Y axis wheels and the scroll wheel. The present invention relates to a mouse that can control X and Y axes and scroll keys by using two light receiving diodes that can limit the number of photodiodes constituting the light receiving portion of a mouse to two by installing six optical fibers that can be transmitted. .

Various devices have been introduced to move the cursor freely on the computer screen and input data. One of the means of securing the largest number of users is a mouse.

There are several ways to control the position of the cursor on the screen using the mouse. In the case of the ball mouse, a ball embedded in the mouse is rotated by the movement of the mouse, and the components installed therein detect the rotation of the ball and control the position of the cursor on the computer screen accordingly. In this case, one light emitting diode and two photodiodes are required for each axis to detect the rotation direction of the X and Y axis wheels installed to detect the rotation of the ball mouse. That is, two light emitting diodes and four photodiodes must be present to detect the X and Y axis movements of the mouse.

In addition, the mouse currently used in the market has a scroll function in addition to the cursor position control function on a general screen, and in order to control the scroll function, a light emitting diode for X and Y axis control and a light emitting diode are separately provided. An additional diode and two photodiodes had to be installed.

Therefore, in the case of a mouse having a scroll function, six photodiodes are required inside the mouse for smooth control of the cursor output on the computer screen. Therefore, three light emitting diodes are required for the control of the X and Y axes and the control of the scroll key function. 9 diodes must be installed in total.

Sometimes the scroll key function is divided into X and Y axes. In this case, four light emitting diodes and eight photodiodes must be installed, so that 12 diodes must be installed in total.

However, when manufacturing a mouse by applying the conventional technology, there are difficulties in mouse design due to many components, and there is a problem of reliability even after completion.

The present invention has been made to solve the above problems, the inside of the mouse in the mouse to control the position of the cursor on the computer screen by irradiating light to the cylindrical bar formed on the surface of the stripe with a predetermined interval and receiving the light reflected from the surface Limit the number of photodiodes installed on the two, and the light emitting diodes irradiate the cylindrical bars and transmit the reflected light to the photodiodes using six optical fibers. It is aimed to provide a possible mouse.

In order to achieve the above object, the present invention is the first and second to irradiate light to the X, Y axis wheel and the scroll wheel is formed with a line of regular intervals on the surface to control the position of the cursor on the personal computer monitor In the mouse provided with a third light emitting diode, the first, second photodiode receiving the light reflected from the X, Y-axis wheel, scroll wheel to output a signal according to the amount of light received, reflected from the X-axis wheel A first optical fiber for transmitting the light to the first photodiode, a second optical fiber for transmitting the light reflected from the X-axis wheel to the second photodiode, and a second optical fiber for transmitting the light reflected from the Y-axis wheel to the first photodiode 3 optical fiber, a fourth optical fiber for transmitting the light reflected from the Y-axis wheel to the second photodiode, a fifth optical fiber for transmitting the light reflected from the scroll wheel to the first photodiode, half at the scroll wheel And the light being composed of a sixth optical fiber to pass to the second photodiode.
