摘要： A copying machine capable of color copying includes a filter apparatus for color-separating scanning light for scanning original images, and the original images are copied by electrophotographic process. The filter apparatus includes mirror filters having color separation filters of blue, green and red, respectively deposited on mirror surfaces and a half mirror, and these mirrors are arranged apart from each other at an angle of 90.degree., so that the apparatus as a whole has a cylindrical shape. The light scanned the original images is reflected by the filter mirrors, and latent electrostatic images corresponding to respective colors are formed on a photoreceptor drum.

摘要： A waiting time display system specifically for use in a copying machine includes a temperature sensor for monitoring the specific temperature of heat fixing rollers. Electronic processing is responsive to the varying signal outputs of the sensor and correspond to the rise of the temperature detected. A display panel is driven so that a plurality of lights are sequentially activated and deactivated to indicate time and temperature. An audio signal can also be provided to indicate the machine can be activated for copying. An operator can now gauge the amount of time until the copy machine is capable of being operative.
