Abstract: There is provided a combined mouse and laser pointer that has a positional information input section provided on the bottom surface, a outer casing in which a laser light outlet through which a laser beam is output to the outside of the outer casing is provided, a mouse function section, a laser pointer function section, and a function selecting section which controls enablement and disablement of the mouse function section and the laser pointer function section, wherein the function selecting section selects and enables either or both of the mouse function section and the laser pointer function section at the same time.

Abstract: An image sensor mouse of a contact-less type is provided which employs a full color light emitting diode 80 having a red (R) light emitting unit diode 801, a green (G) light emitting unit diode 802, and a blue (B) light emitting unit diode 803, and a voltage control integrated circuit 910 which makes selection of one or more of the three unit diodes to be operative by varying a driving voltage applicable across each of the unit diodes separately to vary intensity of the emitted light therefrom, whereby obtaining a mixed light in arbitrary color.
