Abstract: PURPOSE:To eliminate the flapping of a photosensitive belt at an exposure position by providing a run regulating material. CONSTITUTION:A photosensitive belt 10 extended between rollers 6 and 7 flaps in running to cause deviation of the scanning line of a laser beam Lb, but a curved member 11 regulates the run of the photosensitive belt, where exposure is performed to prevent the deviation. In this case, the driving roller 6 is used both as a run regulating member to set a development part right behind it, and consequently dark attenuation is reduced, but it it preferable to perform exposure where the contacting between the photosensitive belt 10 and roller 6 becomes stable at a leading angle theta0 from the beam direction, obtaining advantage in layout.

Title: Photographing device
Inventor: IMAI RYOICHI
IPC: G03B27/32
Filed: 1990-07-04
Abstract: PURPOSE:To surely remove the sagging of a photosensitive body at the time of loading and to accurately detect the residual quantity of film by receiving the signal of detecting that a cover is closed at the time of closing it and removing the sagging of the photosensitive body. CONSTITUTION:When the cover 44 is closed after automatically loading the film, a cover opening and closing detector 45 detects that the cover 44 is closed. According to the detection signal, a reverse rotating motor 43 reversely rotates a real 22 to obtain a state where there is no sagging on the film. After the motor 43 is driven for a specified time, the driving is stopped. Since the torque of the motor 43 is used only to remove the sagging, the small torque is of service. Then, the torque thereof is smaller than the driving force of a supply roller 24, so that it does not reversely feed the film F after the sagging is all removed by reverse rotation, and the film F is normally fed in the feeding direction of the supply roller 24. Therefore, the residual quantity of film is accurately detected.
