Abstract: In an image forming apparatus having an LED print head according to the present invention, the cycle period of a lighting reference clock signal is variably set according to the tone level of image data so as to variably set the lighting period of an LED according to the tone level of the image data. This makes it possible to provide a linear characteristic relationship between the image data and the tone level of a formed toner image for improvement of an image quality.

Abstract: A paper supplying device includes a pair of opposite upper and lower paper supplying rollers, each having a hemicylindrical portion defining an increased frictional circumferential surface having a frictional force greater than the remaining surface of the respective roller. A pair of feed rollers are arranged on a downstream side of the paper supplying rollers at a distance shorter than a circumferential length of the increased frictional circumferential surface of the paper supplying rollers. A rotation change over device drives the paper supplying rollers in changeable rotational directions between a regular rotational direction and a reverse rotational direction. A pair of upper and lower assist rollers are arranged with a bundle of manuscript sheets placed on a paper supplying tray therebetween. The assist rollers are rotated in the same direction synchronously with the paper supplying rollers.

Abstract: An image forming apparatus is provided with a binding function. A container, having a binding mechanism located in the bottom end thereof, is attached to the housing of the image forming apparatus. A guide member movable between a first positions in which the guide member is adjacent to the bottom end of the container, and a second position in which the guide member projects beyond the insertion opening of the container is provided to support a binder which is loaded in the container.

Abstract: An image forming apparatus comprises a copy number setting button for setting the number of copies, magnification setting button for setting the magnification, first storing memory for storing the set number of copies, second storing memory for storing the set magnification, a single display for selectively displaying the set number of copies and the set magnification, a display mode switching key for switching the display mode to the copy number display mode or the magnification display mode, and display mode control for switching the display mode on the basis of input by the above display mode switching key. There is also provided a clear key for clearing the set contents and clear control for clearing the set contents of the display mode currently set out of the copy number display mode and the magnification display mode when key input is provided by the above clear key.

Abstract: A binding unit binds sheets with a binder having an electric heater and electrodes for supplying electric current to the electric heater. The binding unit includes a container and an inner lid. The container has an insertion opening at one end through which the binder is inserted, and electrode terminals at the opposite end which come into contact with the electrodes of the binder. The inner lid is openable and provided in the container between the insertion opening and the electrode terminals. It assumes a closed position covering the electrode terminals when no binder is loaded in the container, and an open position allowing the electrodes of the binder to come into contact with the electrode terminals and at the same time supporting one side of the binder when loaded in the container.

Abstract: An image forming apparatus equipped with a binding function includes an image forming unit for forming an image onto a sheet, a binding unit provided adjacent to the image forming unit, and a malfunction detector for detecting malfunction in the operation of the binding unit. The binding unit is provided with a binding condition display, and the image forming unit is provided with an alphanumeric character display and a device for instructing the start of an image forming operation. A detected malfunction is indicated by at least one of these displays. Upon detection of a malfunction by the malfunction detector, operation of the binding unit stops, or the entire operation of the apparatus stops.

Abstract: In a feed roller for mixing a developer and feeding it to a developing roller, a first mixing wing parallel to a rotating shaft is provided, a second spiral-shape mixing wing is diagonally provided in a manner to cross the first wing, and a spiral-shape groove for feeding a powder is formed on the one side located on the forward section with respect to rotating direction and being the powder scraping-up side of the both sides of said second mixing wing, along said second mixing wing, so as to enhance the feed performance, lateral-mixing performance and lateral-feed performance of the feed roller.

Abstract: An optical system driving device has a motor which rotates constantly in one direction for providing rotary driving power. A regular rotation electromagnetic clutch is connected to the rotating motor for transmitting driving power to the optical system for reciprocal movement of the optical system in one direction. A reverse electromagnetic clutch connected to the rotor motor transmits driving power to the optical system for reciprocal movement thereof in the opposite direction. A control circuit is provided which receives a pulse signal for controlling either the regular rotation or the reverse electromagnetic clutch at the start of the regular rotation electromagnetic clutch to gradually increase the effective driving power provided to the optical system to move the optical system at the start of movement.

Abstract: A system according to the invention has a plurality of sensors, a system control circuit and a plurality of actuators. State data, supplied from the sensors, is compared with characteristic data in the system control circuit. From this comparison, it is judged whether a fault has occurred depending upon whether the state data is relatively lower or higher. If a fault has occurred, fault inference fault is made on the basis of a comparison between qualitative data and fault diagnosis knowledge which are stored in the system control circuit. Then a judgement is made as to which of the elements in an image forming apparatus is abnormal. An actuator operating signal thereafter is generated as a result of this judgement.
