A control method for a multifunction machine includes detecting placement of a document on a document tray, displaying an object in accordance with document placement detection, storing information indicating the thickness of the document set using the object, conveying the document based on the information, and scanning the conveyed document. The object is displayed in accordance with document placement detection while a function selection screen is displayed, the information is received from a user through the object, and the document is conveyed based on the information in a case where execution of the copy function is commanded through a copy screen displayed after selection of the copy function. Even when a user places a document while a function selection screen is displayed, the thickness of the document can be set with certainty, and the document is scanned based on the set thickness.

A medium conveying apparatus includes a conveyance roller to convey a medium, an imaging sensor to sequentially generate a line image acquired by imaging the medium conveyed by the conveyance roller, a processor to detect an inclination of the conveyed medium based on at least two first pixels in the line image, determine whether a part of the conveyed medium has passed through a position corresponding to a second pixel located outside the first pixels based on the line image, and stop conveyance of the medium by the conveyance roller when the detected inclination is equal to or greater than a threshold value and the processor determines that a part of the medium has passed through the position corresponding to the second pixel.

A recording apparatus includes a reading unit reading a medium transported through a medium transportation path and a pair of frames supporting the reading unit. The pair of frames includes a first frame and a second frame that is disposed with an interval provided between the first frame and the second frame in the width direction, at least one of the first frame and the second frame is provided with an opening portion penetrable by the reading unit, and the first frame and the second frame support the reading unit penetrating, via the opening portion, the first frame and the second frame while being disposed between the first frame and the second frame.

An image reading apparatus includes a stacking tray, a feeding roller, a restricting member configured to move to a restricting position and a retracted position, a reading sensor, a reversing roller configured to perform a reversing operation, a first conveyance path, a second conveyance, and a controller. The controller is configured to permit the reversing operation if the controller receives an execution instruction of a double-sided reading job on a sheet having a first size, and prohibit the reversing operation if the controller receives an execution instruction of the double-sided reading job on a sheet having a second size smaller than the first size.

A conveying path for a document (D) includes a first conveying path (R1) that turns back midway, and a second conveying path (R2) that does not turn back midway. When the first conveying path (R1) is used, a first side is read and the document (D) is discharged with the first side facing downward. When the second conveying path (R2) is used, a second side is read and the document (D) is discharged with the second side facing downward. When the second conveying path (R2) is used, a warning message (MS1) is displayed.

A conveyance path for a document (D) has a first conveyance path (R1) that turns back midway and a second conveyance path (R2) that extends rectilinearly. When the document (D) is of a particular type, if a setting to use the first conveyance path (R1) has been made, a control section (4) has a warning message (MS1) displayed.

An automatic document feeder includes a media path to route media through an image read area for the automatic document feeder, and a media ramp supported along the media path after the image read area, with an end of the media ramp to rotate in a direction transverse to the media path.

In a sheet conveyance apparatus a control unit controls lifting and lowering of a sheet supporting portion by a lifting unit and executes a mixed feeding in one of a plurality of modes including a first mode and a second mode. The mixed feeding is an operation in which a plurality of sheets having different lengths in a width direction orthogonal to a feed direction of a sheet feeding unit are fed by the feeding unit, wherein in the first mode, the control unit causes the lifting unit to move the supporting portion from the second position to the first position based on an instruction to start sheet feeding, and in the second mode, the control unit causes the lifting unit to move the supporting portion from the second position to the first position based on a detection of a sheet by the detection unit.

An image processing apparatus includes a motor, a sheet feeding roller, a separation roller, a conveyance roller, a first clutch set provided in a transmission path of a driving force transmitted from the motor to the sheet feeding roller, and a second clutch set provided in a transmission path of a driving force transmitted from the motor to the separation roller. The first clutch set includes a first one-way clutch and a first two-way clutch, and the second clutch set includes a second one-way clutch and a second two-way clutch. A maximum value of a first play angle set between a first transmission portion and a first transmitted portion in the first two-way clutch is larger than a maximum value of a second play angle set between a second transmission portion and a second transmitted portion in the second two-way clutch.

An image reading apparatus, including a feed tray, a conveyance guide, a conveyer, a reading sensor, a first housing, a first driving source, a first driving train, a second driving source, and a second driving train, is provided. The first housing accommodates at least the conveyance guide and the conveyer and has a first outer face and a second outer face facing opposite to each other in a widthwise direction. The first driving source and the first driving train are accommodated in the first housing on a side toward the first outer face. The first driving train transmits a driving force from the first driving source to the conveyer. The second driving source and the second driving train are accommodated in the first housing on a side toward the second outer face. The second driving train transmits a driving force from the second driving source to the movable plate.
