摘要： An overlapped-transfer preventing paper supply device in an image-forming apparatus includes an overlapped-transfer preventing member and a rotary paper supply member in an overlapped-transfer preventing portion. A sheet-returning member returns a sheet located in the vicinity of the overlapped-transfer preventing portion to a sheet source or supply and moves from a downstream side to an upstream side of the overlapped-transfer preventing portion. A drive operates in response to a sheet-returning signal to move the sheet-returning member in a sheet-returning direction. A sheet located in the vicinity of the overlapped-transfer preventing portion can be prevented from being damaged, and jamming due to such sheet can be prevented.

摘要： A housing body includes a first part forming a part of a first transporting path in which a medium is transported. An image forming unit is accommodated in the housing body and is adapted to form an image onto at least one face of the medium. A door cover is attached to the housing body, and the door cover includes a second part adapted to face the first part when the door cover is closed, thereby forming the part of the first transporting path together with the first part. A double-sided printing unit is detachably mounted to the second part and includes a second transporting path. The second transporting path is connected to the first transporting path and is adapted to transport the medium while turning inside out, so that the image forming unit forms images on both sides of the medium.

摘要： An image forming apparatus includes an image forming portion that forms an image on a sheet, a fixing portion that fixes the image onto the sheet by passing therethrough, a sheet discharge portion that discharges the sheet that has passed through the fixing portion to a sheet discharge tray, and a pair of switchback rollers that switch back the sheet that has passed through the fixing portion so as to return the sheet to the image forming portion. The switchback rollers are provided between the fixing portion and the sheet discharge portion. The switchback rollers are provided in a sheet discharge path disposed from the fixing portion toward the sheet discharge portion. The switchback rollers are reversely rotated to switch back the sheet when a nip portion between the switchback rollers nips a rear end portion of the sheet that passes toward the sheet discharge portion.

摘要： A document feeder which has a document transportation path curved with a curvature radius such that a document original is reversed and fed therethrough to a document setting surface. The document feeder further includes a pair of rollers respectively disposed inside and outside of the curvature of the document transportation path in an opposed relation and adapted to hold the document original therebetween for guiding the document original to the document setting surface. The rollers abut against each other in a position upstream of the vertex of the curvature of the document transportation path with respect to a document transportation direction.

摘要： A recycle document feeder according to the present invention includes a cover (251) covering a document discharge portion (30). The cover (251) is openably supported by a pivot shaft (256) between a pair of frames (255). A feed-back path (32) for guiding a document original onto a document placing plate is defined by a pair of guide members (257, 258) provided in an opposed relation. The upper guide member (258) is attached to the interior face of the cover (251). A switch claw (253) for switching the document traveling direction is attached to the pivot shaft (256) which supports the cover (251). Thus, there is no need for additionally providing a shaft for supporting the switch claw (253), thereby simplifying the construction of the document discharge portion (30).

摘要： A density measuring device includes a moving member that can be moved in a liquid, a light emitting member and a light receiving member that receives light emitted by the light emitting member. A gap part in which the moving member is disposed in a path of light emitted from the light emitting member can be moved. A density measuring unit measures the density of the liquid based on the result of output of the light receiving member for a case where the moving member is located in the path of light emitted from the light emitting member and a case where the moving member is not located in the path of light emitted from the light emitting member.
