Title: Color copying machine
Inventor: TOKUYAMA MITSURU
IPC: G03F3/00
Filed: 1990-11-30
Abstract: PURPOSE:To make the image quality of a copy stable even at the switching time when lamp voltage is drastically changed by inserting a color tone correction filter in an optical path at the time of switching an exposing speed. CONSTITUTION:In this copying machine, the lamp voltage of the main exposing lamps 4 and 15 of 1st and 2nd exposing optical systems 1 and 2 is allowed to be switched stepwise. For example, the lamp voltage is lowered stepwise from the channel 1 of the highest voltage to the channel 5 of the lowest voltage by an exposure dial, and it is lowered from the channel 6 to the channel 9 in the same manner. Then, the moving speed of a photosensitive sheet 12 is changed and switched to the 1st exposing speed of the channels 1-5 and the 2nd exposing speed of the channels 6-9. The color tone correction filter 28 is inserted in the optical path of the optical systems 1 and 2 between the channels 5 and 6. Even when the temperature of the lamps 4 and 15 is changed by the sudden change of the lamp voltage and light color is drastically changed, it is corrected to the light color before the change.
