Abstract: A sheet processing apparatus includes a processing tray on which sheets are stacked in a bundle form, an intermediate portion stapler which staples the intermediate portion of the sheet bundle stacked on the processing tray, a sheet bundle conveying member which conveys the stapled sheet bundle, a curved sheet bundle conveying path which is downwardly curved on the downstream side of the processing tray with respect to the sheet conveying direction and adapted to guide the sheet bundle conveyed by the sheet bundle conveying member, and a folding device which is arranged in the intermediate portion of the curved sheet bundle conveying path and which folds the stapled sheet bundle, wherein the processing tray is set to be lower on the upstream side than on the downstream side with respect to the sheet conveying direction, and wherein the curved guide path has an extended portion extending to a position under the stacking portion.

Abstract: The sheet processing apparatus is equipped with a process tray on which sheets conveyed are stacked, a return belt which moves the sheets stacked on the process tray, a trailing edge stopper which receives an end portion of the sheets moved by the return belt, and a conveyance assist roller which comes into contact with the sheets on the upstream side of the return belt with respect to the sheet moving direction and imparts a load to the movement of the sheets. The return belt moves the sheets to which a load has been imparted by the conveyance assist roller and causes them to be abutted on the trailing edge stopper.

Abstract: When a sheet bundle is being conveyed by any one pair of plural pairs of rollers independently movable toward and away from the bundle sheet, before the bound portion of the sheet bundle passes the pair of rollers, the pair of rollers on the downstream side nearest to the bound portion are separated from the sheet bundle, and the pairs of rollers more downstream than that pair convey the sheet bundle. Thereby, it happens less often that the pairs of rollers gather the air collected between adjacent ones of the sheets of the sheet bundle to the bound portion to thereby cause a slack to the sheets, and the occurrence of wrinkles or twists in the sheet bundle can be reduced. Also, the pair of rollers are separated from the sheet bundle before the bound portion passes the pair of rollers, whereby it happens less often that the pair of rollers are damaged by the bound portion, and the sheet bundle can be conveyed smoothly.

Abstract: An object of this invention is to provide an image reading apparatus capable of reading an original image at high speed. And other object is to provide an image reading apparatus in which even when heat is generated at an inverter, reading operation is not influenced. In order to achieve these object, the image reading apparatus is comprised with a scanning means including, a light source for illuminating an original, an image pickup element for receiving reflected light from the original, a cabinet and an inverter provided at a vicinity of a side face of the cabinet in parallel with a direction of moving the light source for driving the light source, a communicating means provided at a vicinity of a side face of the cabinet opposed to the side face at the vicinity of the inverter and a cooling fan for cooling an interval between the inverter and the communicating means.

Abstract: An image reading apparatus having an original base unit on which an original is placed, a light source for illuminating the original on the original base unit, a light-receiving unit for receiving light reflected from the original, air blasting unit for sending air in the direction away from the light source, and a wall surface for allowing air sent from the air blasting unit toward the light source.

Abstract: An image forming apparatus includes an image forming portion disposed within a main body of the apparatus to form an image, a first display attached to an upper portion of the main body to display information regarding the handling of the apparatus, and an open/close mechanism provided on a frame of the main body to be openable opened during the maintenance. In addition, a second display mechanism is disposed at a position viewable by an operator from a position where the open/close mechanism is opened and includes a single display for selectively displaying a plurality of information data.

Abstract: A sheet feeding apparatus capable of separating and feeding sheets each having a flap like an envelope. In the sheet feeding apparatus, when stacked sheets are delivered by a pickup roller supported liftably, and separated one by one by a feed roller for rotating in a sheet feed direction and a retard roller for rotating in an opposite direction to the sheet feeding direction, the pickup roller is moved up and down a plurality of times until a flap of the delivered sheet passes between the feed roller and the retard roller, which makes it possible to prevent buckling of the sheet.
