Abstract: The present invention provides a laminating apparatus comprising a sheet feeder for feeding a sheet on which an image is formed, a laminate film feeder for feeding laminate films, a heater for heating the laminate films being fed, a device for pressurizing the sheet and the laminate films being fed by the sheet feeder and the laminate film feeder, by overlapping the sheet and the laminate films, a temperature for detecting a temperature of the heater, and a controller means for prohibiting a laminate mode when the temperature detected by the temperature detector is lower than a predetermined set temperature.

Abstract: A binding apparatus for binding sheet materials with a covering material having a heat-adhesive agent at its bottom portion by bonding the bottom portion of the covering member and edges of the sheet materials includes a holder for holding the covering material and the sheet materials sandwiched by the covering material; a heater for heating the adhesive agent; a switch for switching power supply to the heater; a detector for detecting setting of the covering material in the holder; and a temperature controller. The temperature controller supplies power to provide a first temperature when the covering material is not set in the holder, supplies power to the heater to provide a second temperature higher than the first temperature when the covering material is set in the supporting member, and supplies the power to the heater to provide the first temperature after the covering member is taken out from the holding member.

Abstract: A sheet binder for binding sheets by adhering the sheets to a back of a cover member by a heat-fusible adhesive. The sheet binder includes a supporting member for supporting the cover member having the back, to an inner surface of which the heat-fusible adhesive is applied, a heat generating member disposed in the proximity of the supporting member, and an alternate magnetic field generating device for generating an alternate magnetic field to heat the heat generating member.

Abstract: There is disclosed a sheet sorter with plural sorting bins, in which a selected bin is automatically switched, when sheets of a predetermined number which varies according to the sheet size, are stored therein, to another bin in order to prevent breakage of bins and to ensure smooth bin movement.

Abstract: A sheet stacking apparatus usable with an image forming apparatus having a sheet discharging outlet includes a sheet stacking portion, a conveyer for receiving a sheet material from the sheet outlet of the image forming apparatus and for conveying the sheet material to the sheet stacking portion, speed controller for changing a conveying speed of the conveyer to provide a first conveying speed while the sheet material is being confined by the image forming apparatus and to provide a second conveying speed which is higher than the first speed after the sheet material is released from the image forming apparatus.

Abstract: A dot printer has an LED array printer head consisting an array of LEDs, drivers for independently driving the LEDs, and time control circuits for controlling ON or OFF times of the LEDs by energizing the drivers in accordance with image data and correction data stored in a memory. The LEDs can be divided into blocks which can be sequentially driven. Variations in mechanical and electrical characteristics of the LEDs are corrected to allow formation of a high-resolution image or a halftone image.

Abstract: A remaining amount indicator for indicating remaining amount of consuming material such as papers, toner, web or silicone oil in a recording apparatus such as a copying machine or a laser beam printer is disclosed. The remaining amount detected by a detector is displayed by a display in a first display mode until the remaining amount reaches a predetermined level, and in a second display mode after the remaining amount has reached the predetermined level. Further, the quantity of the display is reduced as the remaining amount decreases.
