A sorter for sorting recording sheets after image recording by an image forming apparatus is disclosed here. The sorter is provided with a plurality of bins arrayed along a main path of the recording sheet, a plurality of change over gates to guide the recording sheet from the main path to a selected bin, a conveyance mechanism to convey the recording sheet through the main path to the selected bin, a plurality of pinch rollers dispersively located near the gates and the bins to press the recording sheet onto a conveyance surface of a conveyor belt of the conveyance mechanism and a member to back up the conveyor belt from the pressure of the pinch rollers.
摘要:
A paper feed device and method for separating sheets of paper one by one from the bottom of a stack of paper loaded on a paper loading tray and for feeding the separated paper sheets consecutively. The feed device includes a rotatable hollow cylinder having a peripheral surface positioned below and close to the front end of the paper loading tray in the direction of paper sheet feed, and having an opening for drawing a paper sheet against the peripheral surface by vacuum suction. The vacuum suction is variable to set the suction pressure at the low level at the start of a paper sheet feed operation by the cylinder means, and if, after the predetermined time interval, the passage of the paper sheet is not detected, the vacuum suction pressure is increased to a higher level and maintained at the higher level to feed successive paper sheets. A paper sheet front end sensor, a conveyor, and a timer for setting a predetermined time interval after the start of a paper sheet operation, are also provided.

A document ejection device for a document conveyor having a document ejecting roller to eject a document sheet from the document conveyor to the outside of the conveyor, and ejecting speed reduction device which reduces the ejecting speed of the document sheet after the document is passed through the ejecting roller. The ejecting speed reduction device has a reduction roller rotating at a circumferential speed lower than the ejecting speed of the document, and a pressing panel or following roller to press the document onto the reduction roller.

An image recording apparatus includes a memory for storing an image information of each page; an image forming device for recording an image onto a recording sheet for each page on the basis of the image information in the memory; a recording sheet conveyor for conveying a recording sheet to the image forming device to record an image on one side thereof, and after that, conveying again the recording sheet to the image forming device to record an image on another side thereof, with no recording sheet being stacked during conveyance, and the recording sheet being conveyed along a specified conveyance path, and a predetermined maximum number of recording sheets can exist within the specified conveyance path. The apparatus further includes a controller for controlling the image forming device and the recording sheet conveyor so that a cycle of an image forming operation corresponding to the maximum number of recording sheets is repeated until a remaining number of pages in the memory to be recorded is less than the maximum number of recording sheets.

A sorter distributes plural sheets to plural sheet holding bins. The sorter includes the plural sheet holding bins for holding the plural sheets, in which inserting portions of the plural sheet holding bins are aligned in a line in a predetermined direction; a conveyance belt for conveying the plural sheets along the line; a distributor, that is reciprocally movable along the line, for distributing the plural sheets to the plural sheet holding bins; motorized pulleys for winding and unwinding a wire member; the wire member being connected between the motorized pulleys and the distributor; nipping apparatus for nipping and for conveying each of the plural sheets, the nipping apparatus being positioned between the conveyance belt and the wire member.
摘要:
A recording sheet finishing apparatus connected with an image forming apparatus, in which recording sheets delivered from the image forming apparatus are stapled and the stapled sheets are ejected. The apparatus includes a plurality of stackers each having at least one stapler. The apparatus further includes a control means in which the recording sheets delivered from the image forming apparatus are stapled alternately by the staplers for each set of recording sheets and after that, each of the stapled set of recording sheets are delivered from the stapler to a delivery sheet tray, where a conveyor belt which transports the stack is operated at two different speeds with an initial speed followed by a faster speed to prevent damage to the stack.
摘要:
A copying machine is equipped with an automatic document feeder, which separates documents in a document storing section and feeds them one by one onto a platen glass. The documents are stopped at an exposure position by a document conveyance stopper, where they are exposed and scanned by an exposure scanning device, and then delivered to a document delivery tray. A sensor is provided in a feeding path of the document feeder, for detecting a leading edge or a trailing edge of the document. A delaying device for delaying a drive source stopping signal of the document conveyance stopper is outputted after a predetermined period of time has passed, or after a predetermined number of pulses have been counted after the document leading or trailing edge signal outputted from the sensor has been received. A detection device detects the documents actual stopping position and a signal is output after the drive source stopping signal of the document conveyance stopper has been generated. A controller controls the generation of a signal for the recording sheet conveyance operation. The start signal occurs at a time which corresponds to the driving of the exposure scanning device, as adjusted based on a detection at the actual document stopping position by the detection device. The document stopping position is at the location on the platen where the motor drives and transports the original plus the distance that the sheet is carried by inertia.
摘要:
The invention provides an apparatus for feeding a paper in which there are provided a stacker for placing a stack of papers and threefold cylinder for separating the lowermost paper by vacuum suction from the stack of papers placed on the stacker and sequentially feeding the separated paper one by one. The threefold cylinder is disposed below the stacker in the vicinity of the leading edge of the stacker in relation to the feeding direction. And, the threefold cylinder includes a first cylinder rotatable and provided with a number of through holes on the circumferential surface; a second cylinder, installed inside the first cylinder, provided with a slit-shaped opening on the circumferential surface; a third cylinder, installed inside the second cylinder, provided with a slit-shaped opening on the circumferential surface thereof. The third cylinder is connected to vacuum suction.
