摘要:
An automatic document conveying device (4) suitable for use in an image-processing machine (2) having a transparent plate (8). Document delivering means (114) discharge a document after having been processed out of a document delivering passage (124) into a document receiving tray (94,128). Document discharge rollers (140,142) located at the end of the document delivering passage (124) are drivingly connected to driving means (364) such that the peripheral speeds of the discharge rollers (140,142) are slower than the other rollers (116) in the document delivery means (114). One-way clutch means (402) are interposed between the document discharge rollers (140,142) and the driving means (364).
摘要:
An automatic sheet processing device mountable on a sorting unit of an image forming apparatus includes a sheet processor for applying a sheet processing to a sheet having a specified length and width, a moving unit capable of supporting the sheet processor for moving the sheet processor along a side of the sheet, and a controller having a storage unit for storing sheet processing data, a calculator for calculating a processing position from the sheet processing data, and a control portion for controlling the moving unit so as to move the sheet processor to the calculated processing position. The processing position is calculated from the stored sheet processing data, and the sheet processor is moved to the calculated processing position, so that sheet processing can be automatically.
摘要:
An automatic document conveying device to be applied to an image processor with a transparent plate on which to place document to be processed being disposed on the upper surface of a housing. The automatic document conveying device comprises a document table, a document introduction passage extending from the document table to one end edge of the transparent plate, a first document receiving tray, a second document receiving tray and a document delivery passage. The document delivery passage includes a common passage extending from the other end edge of the transparent plate, a first branched passage extending from the downstream end of the common passage to the first document receiving tray, and a second branched passage extending from the downstream end of the common passage to the second document receiving tray. The automatic document conveying device further includes a docunent sending means for delivering a plurality of documents on the document table piece by piece to the document introduction passage, a document introduction means for introducing the document sent out to the document introduction passage onto the document plate, a document conveying means for conveying the document along the transparent plate, and a document discharging means for discharging the document delivered to the common passage of the document delivery passage by the document conveying means through the common passage, the first branched passage or the second branched passage in the document delivery passage.
摘要:
A sorter comprising a plurality of vertically arranged bin trays (32). Each of the bin trays (32) is moved through a predetermined moving passage (78), and the moving passage includes a main portion (80) and a by-pass (82) caused to detour from the main portion (80) to the upstream or downstream side. The sorter also has an automatic stapler (158) and an automatic punch (160). When the bin tray (32) and sheets (170) collected thereon are positioned in the by-pass end portion (156) of the by-pass (82), the sheets (170) are positioned at a stapling position relative to the automatic stapler (158), and the sheets (170) are positioned at an automatically punching position relative to the automatic punch (160).
摘要:
An automatic document conveying device (4) is provided in an image-processing machine (2) having a transparent plate (8) on which to place a document to be processed, the transparent plate (8) being disposed on the upper surface of a housing (6). The automatic conveying device (4) is provided with a document delivery re-introduction section (16) which sends a document delivered through a document introduction section (12) and a central main portion (14) selectively to a first document receiving tray (94), a second document receiving tray (128) or the transparent plate (8) by means of a branching means. The document delivery re-introduction section (16) is provided with a first branched passage (126) for sending a document into the first document receiving tray (94), a second branched passage (130) for sending the document into the second document receiving tray (128), and a re-introduction passage (132) for re-introducing the document onto the transparent plate (8). The document delivery re-introduction section (16) is provided with a first opening-closing member (176) for opening most of the first branched passage (126) and most of the second branched passage (130), and a second opening-closing member (200) for opening most of the re-introduction passage (132) in a state where the first opening-closing member (176) is held at an open position.
摘要:
An electrostatic copying apparatus comprising - a transparent plate -on which to place a document to be copied, - an optical system - for projecting the image of the document onto an electrostatographic photosensitive member in an exposure zone located along the moving path of the photosensitive member, and -a driving means - for reciprocating one of at least a part of the optical system and the transparent plate is characterized in that -said driving means includes - a backward movement restricting means - for stopping the backward movement of said one of at least a part of the optical system and the transparent plate fully accurately at a predetermined forward movement start position.
摘要:
A copying paper guiding device comprising a lower guide plate (204) and an upper guide plate (206) located opposite to each other. The lower guide plate (204) has provided therein laterally in spaced apart relationship a plurality of rising pieces (238) rising from the upper side of its main flat portion (208) and extending in the direction of movement of a copying paper sheet. The upper guide plate (206) has provided therein laterally in spaced-apart relationship a plurality of hanging pieces (240) hanging from the lower side of its main flat portion (228) and extending in said direction of paper movement. Openings (244) are formed on the main flat portion (228) of the upper guide plate (206). The upper edges of the rising pieces co-operate with the lower edges of the hanging pieces to define a path of movement for the copying paper.
摘要:
@ A developing device comprising a developer receptacle for storing a two-component developer composed of carrier particles and toner particles, a magnetic brush mechanism (36) disposed in a front portion within the developer receptacle, a first agitating mechanism (38) disposed in a rear portion within the developer (14) receptacle in a spaced-apart relationship to the magnetic brush mechanism (36), a second agitating mechanism (40) disposed in proximity to, and rearwardly or downwardly of, the magnetic brush mechanism, a developer removing -member (50) disposed between the magnetic brush mechanism (36) and the first agitating mechanism (38) with its front edge being in contact with, or in proximity to, the surface of the magnetic brush mechanism (36), and a toner particle supplier (32) for supplying toner particles to the developer receptacle; is characterized in that a plurality of cuts (54) spaced in the widthwise direction are formed at least in the front portion of the developer removing member (50), and a part of the developer held on the surface of the magnetic brush mechanism (36) is removed therefrom by the action of the developer removing member (50) and caused to flow over the upper surface of the developer removing member (50) toward the first agitating mechanism (38) but the remainder of the developer held on the surface of the magnetic brush mechanism (36) moves through the cuts without undergoing the action of the developer removing member and is caused to flow toward the second agitating mechanism (40).
