Abstract:
A copying apparatus is adapted to suppress the temperature rise of a platen glass by decreasing the copy speed from a first speed to a second speed after the apparatus has copied a threshold number of sheets in succession. The above parameters of the first speed, the second speed and the threshold number are basically predetermined based on the size of the copy paper and the magnification in copying, and modified based in accordance with the source voltage of a lamp to emit scanning light to scan an original on the platen glass.
