摘要： PURPOSE:To prevent colors from being mixed owing to the scattering and falling of a developer by providing an intrusion preventing member which moves associatively with the position shift of a developing device and prevents a developer from intruding the developing device. CONSTITUTION:When a red image is obtained, a red developing device 4 is at a development on position nearby a photosensitive drum 1 and a black developing device 5 is at a distant development off position. Namely, the red developing device 4 is pressed toward the photosensitive drum 1 by a red development pressure cam 15 provided on a shaft 14 through a pressure spring 13 in response to a signal from an operation part to enter a developing operation ready state. At this time, a red developing roll 4a rotates as shown by an arrow 4X to supply a red developer 4b to the photosensitive drum 1 and the black developing device 5, on the other hand, is placed at the development off position sufficiently distant from the photosensitive drum 1 through the operation of a return spring provided to a main-body side plate 22. When a black image is obtained, on the other hand, the red developing device 4 is released from being pushed in response to a signal from the operation part and the black developing device 5 is put close to the photosensitive drum 1.
摘要翻译：目的：通过提供与显影装置的位置偏移相关联的移动防止构件，防止显影剂侵入显影装置，防止由于显影剂的散射和坠落而使颜色混合。构成：当获得红色图像时，红色显影装置4处于感光鼓1附近的显影位置，黑色显影装置5处于远处的显影关闭位置。也就是说，红色显影装置4通过响应于来自操作部分的信号的设置在轴14上的红色显影压力凸轮15而被压向感光鼓1，以进入显影操作就绪状态。此时，红色显影辊4a如箭头4X所示旋转，以将红色显影剂4b提供给感光鼓1，而另一方面，黑色显影装置5被放置在远离感光鼓1通过设置在主体侧板22上的复位弹簧的操作。另一方面，当获得黑色图像时，红色显影装置4响应于来自操作的信号而被释放将黑色显影装置5放置在感光鼓1附近。

摘要： PURPOSE:To provide a both-side copying function in addition to a sheet sorting function and make a sheet stacker much more compact and light, by providing a sheet discharge means capable of inverting and conveying a sheet discharged onto a sheet tray. CONSTITUTION:A sheet, onto one side of which an image is already transferred, is sorted and housed on a sheet tray 61n by a sheet discharge means 69a, 69b, 70. A solenoid 95 is then energized to turn a bell crank 89 clockwise to move down a refeeding roller 70 into contact with the top of the sheet. A lower roller shaft 83 is rotated forwards by a timing belt 85 etc. A spring clutch 87 is engaged and another spring clutch 88 is disengaged so that an upper roller shaft 86 is rotated backwards through a gear train 87a. As a result, the refeeding roller 70 is rotated in the same direction as the upper roller shaft 86 so that the sheet on the tray 61n is inverted and conveyed to transfer an image onto the other side of the sheet.

摘要： PURPOSE:To prevent toner from leaking from a discharging port and a receiving port by providing a shutter which is opened and closed freely between the toner discharging port side and receiving port side of a hopper and shielding the receiving port and discharging port from each other. CONSTITUTION:The hopper 5 for toner supply is equipped with the toner discharging port 5a on its reverse surface and fitted to an image forming device body 1 rotatably around a rotating shaft 5b provided to the top surface part and reverse surface part, and toner is conveyed to the discharging port 5a by a conveyor screw 18 in the hopper 5. The plate type shutter 20 is provided between a developing device 3 and the hopper 5 and fitted rotatably to the hopper 5 by a rotating shaft 21, and the shutter is energized with the force of a spring 22 as shown by an arrow A. When a developing device 3 is moved to a development off position separated from a photosensitive drum 2, the operating member 3c of the developing device 4 is disengaged from the shutter 20, which rotates with the force of the spring 22 as shown by an arrow A and stops where its projection 20a engages a stopper 20d, thereby blocking the discharging port 5a of the hopper 5 with the shutter 20.

摘要： PURPOSE:To make an image forming device small in size on the whole by allowing a developer storage container to move to the 1st position which is positioned in the attaching/detaching direction of the 2nd developing device to and from the image forming device so that the attachment and detachment are stopped and the 2nd position which is separated from the attaching/detaching direction so that the 2nd developing device is allowed to be attached. CONSTITUTION:A electrophotographic sensitive drum 2 as a latent image carrier is fitted rotatably almost in the center of the image forming device body 1 and rotated as shown by an arrow X. Further, two developing devices 3 and 4 are arranged along the drum 2 and allowed to move between a development on position close to the drum 2 and a development off position separate from the drum 2. The developing devices 3 and 4 are developer conveying means which convey a developer to the surface of the photosensitive drum 2 and are equipped with developing rolls 3a and 4a having magnets internally, and the developing devices are so controlled that they approach the photosensitive drum 2 only when performing development.

摘要： PURPOSE:To enable the simple and sure disposal of sheet jamming caused at the time of refeeding of a sheet, by providing a sheet refeeding means for refeeding the sheet housed on a tray, and by supporting the tray rotatably. CONSTITUTION:When a sheet is jammed on a secured tray (provided with a sheet refeeding means comprising a refeeding roller 70 and discharge roller 69) 61n at the roller 70 or 69 during the refeeding of the sheet by the refeeding means, an operating person turns movable trays 611-61n-1 together to enlarge the space between the secured try and the movable trays. The operating person then easily puts high hand into the enlarged sheet stacking space A over the secured tray 61n to dispose of the jamming of the sheet. After that, the operat ing person turns the movable trays 611-61n-1 back to a prescribed inclination angle.

摘要： PURPOSE:To carry out multiple functional processes such as double sided copying by stacking sheets having one side copied on a pin tray and then supply again the sheet from the pin tray to a copier by a sheet resupply means. CONSTITUTION:When the tail end of a sheet passes by an auxiliary guide member 81, said member 81 is returned by its own weight to turn off a detecting switch SW1 and reverse a motor so that a pair of first discharge rollers 64 are supplied from the tray side toward a flapper 63, while the leading end of the sheet abuts against the end of the member 81 and is guided by same to a path 65. The first sheet is guided by a second flapper 66 to be sent to a pair of second discharge rollers 69. Since the upper and lower rollers are both rotated forward and a resupply roller 70 is in the lifted position, the sheet is discharged onto a fixed tray 65n by a pair of rollers 69 and once reversed by said pair of rollers 64 so that the sheets are received on a tray 65n with the copy surface being directed downward and guided to a path 68 for multiple copying.
