Abstract:
An image forming apparatus includes accommodating assembly for accommodating a plurality of developing devices on stages arranged substantially vertically and having first driving mechanism for moving the developing devices in a substantially horizontal plane, an image formation assembly for receiving selected one of the developing devices moved out of the accommodating assembly and for further moving it in a substantially horizontal plane, the image formation assembly including systems for forming images using the developing device, the accommodating assembly further including an opening for allowing a the developing device to be loaded into the accommodating assembly.
Abstract:
An image forming apparatus includes an image forming station for conveying a sheet material along a lateral reference position and for forming an image on the sheet material; refeeding device for refeeding to the image forming station the sheet material on which the image has been formed in the image forming station; means, provided in the sheet refeeding means, for shifting the sheet material in the lateral direction from the lateral reference position by a predetermined amount, wherein the amount of the shift is predetermined on the basis of a change in a lateral dimension of the sheet material resulting from an image forming operation in the image station.
Abstract:
An image forming apparatus capable of effecting plural image forming operations on one transfer sheet includes an image transfer device for transferring an image on the transfer sheet, an image magnification changing mechanism for changing the magnification of the image to be transferred onto the transfer sheet, and a control device for controlling the magnification changing mechanism in accordance with deformation of the transfer sheet caused by an image forming operation on the transfer sheet, after a first image is formed on the transfer sheet and before a second image is formed on the same transfer sheet, whereby those images are correctly registered.
Abstract:
A bind tape abutted against a bound edge of a sheet bundle for book-binding the sheet bundle includes a tape substrate and an adhesive layer coated on one surface of the tape substrate to bond the sheet bundle. The bind tape is provided at both longitudinal end portions thereof with areas on which the adhesive layer is not coated.
Abstract:
A book binding apparatus comprises a convey means for conveying a sheet on which an image was formed by an image forming means, a plurality of sheet supporting means for supporting a sheet bundle to align ends of the sheets, a switching means for selecting one of the sheet supporting means to send the sheet conveyed by the convey means to the selected sheet supporting means, a bind means for adhering a bind tape to an end of the sheet bundle, and a move means for moving the aligned end of the sheet bundle supported by the sheet supporting means to the bind means.
Abstract:
An image forming apparatus includes sheet accommodating cassette for accommodating sheets, a device for forming images on the sheets, a first sheet conveying passage for conveying the sheet to the image forming device from the sheet accommodating cassette, a conveyor for accommodating a bundle of sheets having been subjected to an image forming operation by the image forming means at first sides thereof in a form in which leading edges of the sheets are gradually deviated in a sheet advancement direction, and for conveying the bundle as a whole, a feeder, disposed downstream of the conveyor with respect to the sheet advancement direction, for feeding one by one the sheets of the bundle from the sheet closest to the feeder, a second sheet conveying passage merging into the first passage for refeeding to the image forming device the sheets fed by the feeder, and a confining device for confining the sheets of the bundle other than the sheet being fed by the feeder.
Abstract:
A document feeding apparatus comprising a first original supporting device on which an original is placed, an original inlet port for receiving the original placed on the first original supporting device, a conveying device for guiding the original fed from the inlet port to a predetermined position and exhausting the original from the predetermined position, and a second original supporting device mounted on a housing of the document feeding apparatus and having an image area designation device for designating an image area of the original. In an image area designation mode of the apparatus, the original is placed on the image area designation device, a desired image area is designated, and the original is placed on the first original supporting device and is guided to the predetermined position through the inlet port.
Abstract:
An image forming apparatus includes a plurality of the developing devices for developing the latent image formed on an image bearing member. The plural developing devices are each movable between its developing position for developing the latent image on the image bearing member and its retracted position away from the image bearing member. The image forming apparatus includes a shutter for selectively opening and closing the developing aperture of the developing device of one of the developing devices. The shutter opens and closes the developing aperture of said one of the developing devices in association with movement of the other developing device between the developing position and the retracted position.
