摘要： PROBLEM TO BE SOLVED: To perform a separation feed by air, even in a plurality of sheet materials mixing the sheet material in different size. SOLUTION: A suction conveying means comprises the first suction conveying means conveying a document P of large size and the second suction conveying means conveying a document P of small size. The first/second suction conveying means, while individually suction conveying a plurality of the documents P loaded on document trays 36, 40, conveys the document P separated sheet by sheet by separating means 35, 39. Here, in the case of loading the document P of different size mixed on the document trays 36, 40, the respective sized document P is suction conveyed respectively by each of the first/second suction conveying means.

摘要： PURPOSE: To stably float sheets even if the number of the sheets on a sheet stacking tray becomes less than a specified number. CONSTITUTION: An opening 40 is formed at a downstream end of a sheet stacking tray 1. This opening 40 is clogged by a sheet truing-up guide plate 2 when the sheet stacking tray 1 is located at a lower position, but when the sheet stacking tray 1 is raised to a specified level with sheets S fed, the opening 40 is not clogged by the sheet truing-up guide plate 2. In this constitution, a part of the air blown from a nozzle 19 is led below the sheet stacking tray 1 passing through the opening 40, reducing the volume of the air blown to the sheets S, preventing the disorder of the sheets S. As a result, the sheets S float stably.

摘要： PURPOSE: To form a toner image and an ink image on the same recording material without being accompanied by the scaling-up of an apparatus main body and image deficiency. CONSTITUTION: A toner image is transferred to the recording material P supplied from a paper feed device 30 in the first image forming part 11 of a first image forming means 10. This recording material P is fed by a feed belt 12d. An ink image is bonded to the recording material P by the ink jet recording part 21a of the second image forming part 21 of the second image forming means 20 arranged in opposed relation to the feed belt 12d. At this time, in order to prevent that the unfixed toner image is disturbed by the impact of the ink against the surface of the recording material, a restriction means 22 is arranged. The restriction means 22 is constituted of a corona charger and charge having polarity reverse to that of the toner image on the recording material P is applied to the restriction means. By this constitution, the unfixed toner image is electrostatically restricted on the surface of the recording material P and the disturbance of toner at the time of the impact of ink is prevented.

摘要： PURPOSE:To prevent an improper refeed of a sheet material so as to reduce a loss time when refeed paper. CONSTITUTION:A sheet material after forming an image in a surface is conveyed along a conveying surface and released in a lateral direction along an extension surface by a paper discharge roller 31b. The released sheet material is moved by maintaining a plane-shaped attitude, to collide against a butt part and to stop moving in the lateral direction. Thereafter, the sheet material is freely dropped down and loaded on a loading surface 32a. Here by setting point end drop height h1 in the point end equal to rear end drop height h2 in the rear end, of the sheet material, the sheet material is left as maintaining the plane-shaped attitude, to make its point/rear end lead to the loading surface 32a almost simultaneously. Thus by improving a position and attitude of the sheet material when loaded, thereafter in the case of performing a refeed of paper by arm air paper feeder 50, a good refeed of paper cap be realized. Loading paper and refeeding paper can be performed in a short time.

摘要： PURPOSE:To provide a paper feeder which does not generate defective paper feeding both in the case of a small-sized sheet and in the case of a large-sized sheet delivered lengthwise and in addition whose constitution is simple. CONSTITUTION:Air is jetted toward the tip of a sheet on a tray 100 by means of an air blowing nozzle 106, and at the same time air is also jetted toward the sheet side ends by means of nozzles 124, 125 fixed at side regulating slabs 120, 121. In this constitution, it becomes possible to blow air in to the rear end of a large-sized sheet placed lengthwise on the tray 100. As a result, large- sized sheets can be surely separated from each other one by one and can be fed (delivered lengthwise). Also, by controlling by means of a valve air jetting to the sheet side ends that is by means of the nozzles 124, 125 and conducting this air jetting only at the time of large-sized sheet feed, the flapping of small- sized sheets and defective paper feeding caused by it can be prevented.

摘要： PURPOSE:To recycle toner and to prevent increase in the size of an image forming device as mush as possible by providing a means for continuously removing foreign matters mixed in recovered recycled-toner, in a cleaning device. CONSTITUTION:Toner containing foreign matters, collected in the cleaning device by a cleaning blade 14, is separated into the toner and the foreign matters by efficiently vibrating a pair of magnetic-force--generating members and a filter 17. The toner is carried to a sleeve 19, and the foreign matters remain on the side of a sleeve 18 to be recovered and stored in a recovering part 26. The toner carried to the sleeve 19 is scraped off by a blade 24 and then supplied to a developing device by means of a screw conveyor 22. A scraping member 25 scrapes off the foreign matters which have reached, however, the small piece of toner is allowed to pass as it is and reaches the separating position again to be carried to the sleeve 19. Because of such an action, allmost none of toner exist in the foreign matters reaching the recovering part 26.
