摘要： A method for controlling a copying machine having a copying cycle and fusing device. The fusing device is formed of a rotatable heating roller and a press roller in mutually forcible contact with the heating roller, which fuses a toner image on a copying paper at a fusing temperature upon passage through the rollers. The heating roller is heated to a first temperature above the fusing temperature. The copying cycle is delayed during a first interval of time after the heating roller reaches the first temperature. The copying cycle is set to a wait-reset state after the first time interval. The heating roller is cooled to a second temperature below the fusing temperature and the copying cycle is set to a wait state. The heating roller is heated from the second temperature to the fusing temperature during a second interval of time. The copying cycle is restored to the wait-reset state during the second time interval before the heating roller reaches the fusing temperature. The copying cycle is restored to the wait-reset state before a leading edge of the copying paper reaches the fusing device. In addition, the fusing device is at the fusing temperature when the leading edge passes between the rollers.

摘要： A copying machine which develops an electrostatic latent image corresponding to an original image into a toner image, transfers the toner image on the copying paper and fuses the toner image later on the copying paper by means of a heating and fusing device, detects types of copying papers to be transferred by the toner image and when the copying paper is large in size, a fixed standstill time is arranged between the scanning and exposing operation of an original and a restoring operation to a home position is made and a fusing operation is prevented without fail when a temperature of the heating and fusing device drops below a fusing temperature.

摘要： An apparatus for regulating the movement of a movable member includes a drive device for moving the movable member in a first direction from a rest position to an operative position and for moving the movable member in a second direction, opposite to the first direction, from the operative position toward the rest position. A first detector detects the presence of the movable member at the rest position. A second detector detects the presence of the movable member at a location adjacent the rest position but upstream thereof with respect to the second direction. A control arrangement is operatively connected to the drive device and to the first and second detectors to operate the drive device to move the movable member in the first direction and then in the second direction, to stop the drive device upon detection of the movable member moving in the second direction at the location by the second detector, whereafter the movable member continues movement by inertia in the second direction from such location to the rest position and is detected thereat by the first detector, and too, if the movable member is not detected at the rest position by the first detector within a predetermined time period after the detection by the second detector, again starting the drive device to move the movable member in the second direction until detection thereof by the first detector.
