Abstract: A light source drive controlling device for use in an image forming apparatus is provided for controlling a light source for illuminating a surface of a document wherein the light amount of the light source is adjusted in accordance with a level of drive voltage supplied thereto by a light source driving device for supplying a drive voltage of a specified level to the light source. A scanning mechanism for moving the light source to and from a home position and a return position whereat scanning is completed moves the light source through an image reading start position whereat scanning an image of the document begins. A drive voltage supply timing controller varies a drive voltage supply start timing for applying the drive voltage to the light source in accordance with the level of drive voltage such that the light amount of the light source reaches a predetermined level when the light source reaches the image reading start position.

Abstract: A device is disclosed for use with an image-forming apparatus, and includes a binder receiving portion for receiving a binder having papers and an adhesive therein, and a heating member for causing heating and melting of the adhesive in the binder when the binder is fully inserted in the binder receiving portion in order to adhere the papers in the binder. The heating member includes a contact element mounted in a bottom portion of the binder receiving portion and adapted to be contacted against by a contact portion of the binder. A power supply is provided to operate the heating member. A paper supply table is mounted to the binder receiving portion for use in feeding paper into the image-forming apparatus, and the paper supply table includes paper regulating guides which are adjustable in their relative positions to guide different sized papers into the image-forming apparatus.

Abstract: Near a discharge device (48) for discharging paper (P) with an image formed thereon, there is provided a punch (7) for punching holes. The drive of the discharge device (48) is controlled so that the punch punches the punch holes in the trailing portion of the paper (P), without causing creasing or tearing or change in the quality of the paper (P). The punch (7) includes punching cutters (72) and a punching die (74). The punching cutters (72) and the punching die (74) are provided in a unit (U) which can be drawn out of a casing (1) covering the punch (7). With the unit (U) drawn out of the casing (1), jam recovery can be easily executed. The unit (U) is movable in the width direction of the paper (P), thereby making it possible to adjust the position of punched holes. A collecting box (76) for collecting paper scraps (P1) is disposed in the unit (U). If the collecting box (76) is pivoted or the opening (76a) thereof is lifted up when the unit (U) is pivoted, the paper scraps (P1) therein will not fall out.

Abstract: An image-forming apparatus is provided with a bookbinding device having a binder receiving portion. The binder receiving portion is provided with a heat source for heating an adhesive or with an electrode for electrifying the electric heating member on a bottom portion thereof so that a plurality of papers disposed in a binder can be adhered to the inner surface of the back cover of the binder by heating and melting the adhesive with the heat source or the electric heating member. The heat source or electrode is swingably mounted in the binder receiving portion for movement between a bookbinding position and a retracted position. An operating mechanism is provided for moving the heat source or electrode from the retracted position to the bookbinding position upon insertion of the binder into the binder receiving portion.

The binder receiving portion is provided with a cleaning mechanism for cleaning the heat source or electrode, and an operating mechanism for causing the cleaning mechanism to clean the heat source or electrode either when the binder receiving portion is pivoted from a non-use position to a use position or when a binder is inserted into the binder receiving portion.

Abstract: An image forming apparatus having a main body with an opening portion provided in one face of the main body, and a thermal transfer printer. The thermal transfer printer records desired information additively on paper on which a toner image has been fixed. The printer uses a thermal head to press an ink-ribbon on the paper. The thermal transfer printer includes a casing in which a cassette for housing the ink-ribbon is detachably mounted, a thermal head support for supporting the thermal head, and an interlocking mechanism. The interlocking mechanism retracts the thermal head with the thermal head support in response to retraction of the casing. Thus, it is possible to detach the cassette from the main body through the opening portion. This facilitates replacement of cassettes and clearing of paper jams.

A binder-insertion hole of the binder receiving portion is provided with a cover to prevent foreign matter from entering the binder receiving portion.

Abstract: An image forming apparatus can be achieved as, for example, a copying machine. The copying machine according to the present invention includes a handy scanner provided detachably from the main body of the copy machine and an additional data recording device for recording data read by the handy scanner as additonal data in addition to a mechanism for reading an image of a document disposed on an original glass plate to copy the same onto recording paper. The handy scanner can read arbitrary image data such as a figure, a designed character or a logotype. The image data read by the handy scanner is applied to the additional data recording device. If the paper on which the document image has been copied is provided to the additional data recording device, the additional data recording device records the additonal data at the rear of the paper on which the document image has been copied.
