Abstract: A sheet post-process apparatus includes a waiting tray and a processing tray. The waiting tray is provided in the middle of a conveying path so that a downward side end in a conveying direction of sheets is oriented upwardly. In the case where a post-process is required, sheets are made standby. The processing tray has a function which causes the sheets made standby on the waiting sheet to be dropped by self-weight. With this function, the processing tray receives the sheets moved to be dropped and the sheets conveyed from the conveying path without intervening the waiting tray, before carrying out the post-process. In addition, an upstream side end in a conveying direction of the sheets on the waiting tray and a downstream side end in a conveying direction of the sheets on the processing tray are allocated to overlap on each other in the conveying direction of the sheets.

Abstract: A waiting tray is provided in a sheet-conveying path and holds sheets if the sheets need to be post-processed. A processing tray receives sheets conveyed from the waiting tray. It may receive sheets conveyed through the sheet-conveying path and coming not via the waiting tray, before the sheets are post-processed. A conveying mechanism is provided, which causes the sheets to fall, due to gravity, from the waiting tray onto a processing tray. A sheet-aligning mechanism aligns the sheets on the processing tray, at their transverse edges and longitudinal edges. On the processing tray, the sheets are post-processed, forming a bundle. The conveying mechanism conveys the bundle of sheets to a storage tray. Input rollers are spaced by a vertical distance from sheet-feeding rollers which are positioned at upstream of the waiting tray.

Abstract: A sheet post-process apparatus has a standby tray for putting a sheet delivered from an image forming apparatus on standby, a process tray arranged under the standby tray for stacking the sheet dropped from the standby tray or the sheet delivered from the image forming apparatus not through the standby tray, a matching mechanism for matching a lateral direction of the sheet stacked on the process tray by a lateral matching plate to form a sheet bundle, a post-process mechanism for post-processing the sheet bundle matched by the matching mechanism, and a delivery tray for delivering the sheet bundle post-processed by the post-process mechanism, in which the process tray and the standby tray are arranged so as to make a height of an upper end of the lateral matching plate of the process tray higher than a height of a lower end of the standby tray.

With this function, the processing tray receives the sheets moved to be dropped and the sheets conveyed from a conveying path without intervening the waiting tray, before carrying out the post-process. Bundles of sheets formed on the processing tray are stacked onto a storage tray by means of a sheet-conveying mechanism after they have been post-processed.

Abstract: A sheet post-process apparatus of the present invention, when sending sheets of paper collected on a standby tray to a processing tray, has a standby tray realizing an improved lining capacity of sheets of paper and a pair of tray members for loading ejected sheets of paper is formed so as to project from the wall face of the standby tray.

Abstract: The sheet side guiding device includes a tray on which sheets are placed, a side guide provided on the tray to be slidable in a direction normal to the feeding direction of the sheet and configured to guide side portions of the sheets to be fed, a rubber sheet provided on the tray in the sliding direction of the side guide, a lever provided pivotably on the side guide via a pivot mechanism and an engagement stopper nail portion provided for the end portion of the lever and configured to detachably engage with the rubber sheet to lock the side guide to the tray.

Abstract: The present invention provides an image forming apparatus in which an automatic double-side unit 81 is provided free to open and close on the side of an apparatus body 1a, and a manual paper feeding device 61 is provide adjacent to the automatic double-side unit. And, there are provided manual moving mechanisms 75, 86, 86a for moving the manual paper feeding device in a direction away from the side of the apparatus body in association with opening operation of the automatic double-side unit.

Abstract: In an image forming apparatus provided with both-side copying and overcopying functions, a copied paper is fed into a paper stacking unit before being fed again. In the conventional paper stacking unit, since the unit is disposed horizontally, there exists a problem in that paper is not well aligned, thus resulting in paper jamming, double paper feeding, etc. To overcome this problem, the paper stacking unit is disposed with an inclination angle paper feed-out side up. For further improving paper feed reliability, the stacking unit includes a paper lifting device, a paper side alignment device, and a paper curl correcting device.

Abstract: A sheet supplying apparatus supplies sheets one by one from a paper cassette to a transfer portion defined between a photosensitive body and a transfer charger in a housing. The sheet is picked up by rotation of a pair of feed rollers. The picked-up sheet is aligned by register rollers. The feed rollers are driven in synchronism with the operation of the register rollers.

Abstract: Disclosed is a developing device, which develops an electrostatic latent image by applying a toner thereto. The device is provided with an auto-toner adjuster, which detects the toner content of a developing agent, and resupplies the toner in accordance with the detected value, thereby keeping the toner content constantly at a predetermined value. At the shipment from the factory, the developing device is sealed hermetically, storing the developing agent used in setting the toner content by the toner adjuster.

Abstract: A developing device develops an electrostatic latent image formed on a photosensitive drum by using a magnetic developer. The developing device comprises a body frame having a storage section storing the magnetic developer, a developing roller disposed inside the body frame and including a first section facing the storage section and a second section facing the photosensitive drum, for supplying the magnetic developer in the storage section to the second section through the shift of a magnetic field, whereby the magnetic developer supplied to the second section by the developing roller is attracted to the electrostatic latent image on the photosensitive drum, and an intermediate plate provided in the frame body under the developing roller to bear thereon the magnetic developer dropped from the developing roller.

Abstract: In a developing device, a developing roller is disposed at a fixed position to oppose an electrostatic latent image-forming surface rotating in one direction, and a submagnet roller is disposed to be parallel to the electrostatic latent image-forming surface, to have an axis perpendicular to the one direction, and to oppose the developed area opposing the developing roller at a downstream side from the developing roller along the one direction. The developing roller supplies a magnetic developing agent by a magnetic force to that portion of an electrostatic latent image which opposes the developing roller and is defined as a developed area to develop the electrostatic latent image in the developed area by the magnetic developing agent.

Abstract: A developing apparatus for developing an electrostatic image on an electrostatic image bearing member.

Abstract: A clam-shell type image-forming device such as photocopying or facsimile machine has an upper unit and a lower unit hinged to each other at one side. Access to internal parts, such as the photosensitive member, is gained by unlocking the two units from each other and rotating the upper unit upward. A subframe is included within the upper unit and contains the photosensitive member. When the upper unit is opened, the subframe may be lowered to position the photosensitive member for easy inspection and removal.
