PURPOSE: A wheel mouse capable of adjusting a sound is provided to control a sound of an operation system easily by transmitting a code value being generated through a simple operation of a sound adjusting wheel of a mouse to a CPU of a computer. CONSTITUTION: A mouse case includes the left and right click buttons. A rotation disk(8) is supported in the mouse case. The rotation disk(8) includes a plurality of penetration slits(10) which are formed. The rotation disk(8) is mounted between a light emitting diode(6) and a light receiving diode(7) which are mounted interactively. A rotation unit rotates the rotation disk(8), and the penetration slit(10) passes between the light emitting diode(6) and the light receiving diode(7). |
