Abstract
PURPOSE:To achieve the cost reduction and miniaturization of a copying machine by lighting fluorescent lamps for exposure and destaticizing with one unit of lighting device. CONSTITUTION:At the original reading, fluorescent lamp terminals 17a, 17b and lighting device lamp terminals 19a, 19b are respectively connected by a controlling relay 20 which receives a controlling electric power source 21, by which a fluorescent lamp 15 for exposure is lighted and the original is read. Next, immediately after the original is read, a command is emitted by the controlling electric power source 21 to operate the controlling relay 20 to connect destaticizing fluorescent lamp terminals 18a, 18b and lighting device lamp terminals 19a, 19b, whereby a destaticizing fluorescent lamp 16 is lighted and the electrostatic latent images of a photosensitive drum are destaticized. After the destaticization, the controlling electric power source 21 immediately returns to the state that the fluorescent lamp 15 for exposure is lightable. In this way, the cost reduction and miniaturization of the copying machine may be achieved.
