Abstract: An image reading apparatus includes a document tray, a common transport route, a curved transport route, a linear transport route, a switching device, a document transport device, a first image sensor, a second image sensor, a trailing edge detector, a multi feed detector, a leading edge detector, and a controller. The controller determines a length of the document in the transport direction, on a basis of a time point that the leading edge detector has detected the leading edge of the document, a time point that the trailing edge detector has detected the trailing edge of the document, and a time point that a detection status of the multi feed detector has been switched to a non-detection state, and guides the document to the curved transport route or the linear transport route from the common transport route, according to the length of the document, by controlling the switching device.

Abstract: A document conveying device (9) includes a sheet feeding tray (44), a discharge tray (43) provided below the sheet feeding tray (44), a feeding roller (51), a conveying mechanism (35), a lifting mechanism (38) which lifts and lowers the sheet feeding tray (44), a discharge tray document sensor (18) which detects the document on the discharge tray (43), and a control part (10) which controls the lifting mechanism (38) such that the document placed on the sheet feeding tray (44) is pressed against the feeding roller (51) when the conveying mechanism (35) conveys the document. The control part (10) controls the lifting mechanism (38) to lower the sheet feeding tray (44) by a larger amount in a case where the document is not detected by the discharge tray document sensor (18) when power is turned on than a case where the document is detected by the discharge tray document sensor (18).

Abstract: A fixing device includes a fixing member, a pressuring member, a temperature sensing part and an air blow controlling part. The fixing member heated by a heat source heats a toner image on the recording medium. The temperature sensing part includes an infrared sensing element sensing infrared rays from the fixing member and a condensing member condensing the infrared rays to the infrared sensing element. The air blow controlling part executes and stops the air blow to the temperature sensing part. Detection temperature of the fixing member is calculated with a sensing value by the infrared sensing element. The detection temperature or control temperature of the heat source is corrected with air blow condition by the air blow controlling part and temperature deference between the infrared sensing element and the condensing member. Heating of the fixing member is controlled with the corrected detection temperature or the corrected control temperature.

Abstract: An image reading device includes a document tray, a linear conveyance path, a curved conveyance path, a document conveyance device, a scanning device, a length detecting device, an operation device, and a controller. A plurality of conveyance rollers are disposed at a predetermined first interval in the linear conveyance path. In the curved conveyance path, a plurality of conveyance rollers are disposed at a predetermined second interval longer than the first interval. When accepting through the operation device an instruction for conveying an original document through the curved conveyance path, the controller allows conveyance of the original document through the curved conveyance path when a length of the original document detected by the length detecting device is not shorter than the second interval or disallows conveyance of the original document through the curved conveyance path when the detected length of the original document is shorter than the second interval.

Abstract: Conveyance modes include a registration mode accompanied with skew correction and a registrationless mode unaccompanied with skew correction. When a jam occurs, the controller interrupts a job, and invokes blank-feed processing starting from a state with all sheets re-set. On invoking blank-feed processing, the controller checks the conveyance mode and recognizes the number of jams. If the conveyance mode is the registration mode and in addition the number of jams has not reached a threshold number of jams, the controller invokes blank-feed processing in the registrationless mode.

Abstract: The document feeder includes a lift plate, a pickup roller, a lift motor, a retard roller, and a control unit. In a manual feed mode, the control unit rotates the retard roller to feed a document in a document conveyance direction. Further, the control unit causes the lift motor to start lowering the lift plate while the pickup roller is feeding a document after starting to rotate the pickup roller. When there is a document set on the lift plate at the time when the pickup roller stops, the control unit automatically resumes the feeding in the manual feed mode.

Abstract: An image reading apparatus includes a manuscript reader, a communication device, a distance determination device, a manuscript leaving determination device, a controller, and an approaching person determination device. The manuscript leaving determination device determines whether a manuscript is left in the image reading apparatus. The communication device performs wireless communication with a portable device carried by a user. The approaching person determination device determines presence and absence of a person approaching the image reading apparatus. The controller transmits, to the portable device, warning information indicating a risk of information leakage when the distance determination device determines that a distance between the image reading device and the portable device has reached a predetermined first threshold value and the approaching person determination device determines that there is an approaching person in a state in which the manuscript leaving determination device has determined that a manuscript is left in the image reading apparatus.

Abstract: Provided is an inexpensive image forming apparatus that reduces wasteful operation and is capable of determining whether a fixing unit is attached properly. The image forming apparatus includes an image forming apparatus main body, and a fixing roller that fixes a pattern composed of toner on paper by heating when conveying the paper on which the pattern is formed, and uses a fixing unit that can be attached to and detached from the image forming apparatus main body. A temperature sensor for detecting the temperature of the fixing roller is provided in the fixing unit. The image forming apparatus includes a control unit that, after the fixing unit is attached, determines whether or not the fixing unit is attached properly to the image forming apparatus main body according to a magnitude relationship between the temperature detected by the temperature sensor and a preset first threshold value.
