A color conversion laser pointer with a timer comprises a timer device (10), a laser body (20), and a laser color conversion unit (30). The timer unit (10) displays all selections, which can be set for each reservation registration item, on a display means according to the setting of the reservation registration items such as a time reservation day, a time reservation date, an operation start time, an operation stop time, an input signal, etc. The laser unit (20) includes a current control circuit for controlling the generation of a laser beam and a scanning apparatus for generating the laser beam. The color conversion display unit (30) includes a conversion circuit for converting each output of a low pass filter circuit of a group in the same phase and frequency, has a matrix coefficient which can be switched according to the form of a selected color component signal, and converts the selected color component signal into a second digital color component signal. The color conversion laser pointer with a timer according to the present invention can provide visual effects and enables a user to recognize a passage time by the color conversion of the laser pointer with the progress of certain work. |
