摘要： A medium guiding device includes an upstream side rollers pair, a downstream side rollers pair, a first rib, a second rib and an interlocking part. In a first conveying state where the medium is conveyed while being held by the upstream side rollers pair and separated from the downstream side rollers pair, the interlocking part retreats the first rib from a curved path and protrudes the second rib into the curved path. In a second conveying state where the medium is conveyed while being held by the downstream side rollers pair, the interlocking part protrudes the first rib into the curved path and retreats the second rib from the curved path.

摘要： A document conveying device of the present disclosure includes a feeding unit, a stopper, and a restriction surface. The feeding unit is swingably supported on a first swinging fulcrum and is disposed selectively at a paper feeding position or at a retracted position. The stopper is swingably supported on a second swinging fulcrum, and has a document restriction portion and an engagement piece. The restriction surface is provided on the main body side of the document conveying device, and extends downward from a position coinciding with a first trajectory toward an inner side of the first trajectory, while extending downward from a position coinciding with a second trajectory toward an inner side of the second trajectory. When the feeding unit is at the retracted position, the engagement piece is engaged with the restriction surface, and when the feeding unit is at the paper feeding position, the engagement therebetween is released.

摘要： A first opposing portion of the coupling includes first latchet hook and a second opposing portion of the second rotary body includes a second latchet hook. One of the third opposing portion of the coupling and the fourth opposing portion of the first rotary body includes a cam and the other one includes a cam face. When the first rotary body rotates in a forward direction, a camming action turns on the transmission of torque. When the first rotary body rotates in a backward direction, the transmission of torque is turned off. A protrusion protruding from a first end face of one of the third opposing portion of the coupling and the fourth opposing portion of the first rotary body comes into contact with a second end face of the other one of the third opposing portion and the fourth opposing portion while the transmission of torque is turned off

摘要： A locking mechanism includes a hook, an engaged portion, and a biasing member, and locks a movable unit supported on a unit main body to the unit main body. The hook has a supporting portion pivotably supported on the unit main body and an engaging portion protruding from the supporting portion. The engaged portion is formed on the movable unit and is engageable with the engaging portion. A biasing member biases the hook in such a direction as to let the engaging and engaged portions engage. The hook has a first face facing the engaged portion at the tip end of the engaging portion and a second face extending from the first face toward the supporting portion and inclined relative to the first face in such a direction as to recede from the pivot. With the engaging and engaged portion in engagement, the engaged portion touches only the second face.

摘要： A transfer unit includes first and second rollers, a roller switching mechanism, and upstream-side and downstream-side guides. The second roller is arranged downstream of the first roller in the conveyance direction of the recording medium. The roller switching mechanism selectively arranges the first or second roller at a reference position to form a transfer nip. The upstream-side and downstream-side guides are respectively arranged upstream and downstream of the transfer nip in the conveyance direction of the recording member. When the first roller moves to the reference position by the roller switching mechanism, the second roller moves to a first retracted position behind the downstream-side guide, and when the second roller moves to the reference position by the roller switching mechanism, the first roller moves to a second retracted position behind the upstream-side guide.

摘要： A sheet discharge device includes: a sheet discharge portion; a sheet stacking portion having a sheet stacking surface for stacking a sheet discharged from the sheet discharge portion; and a stopper in the sheet stacking portion against which, for alignment, the leading end of the sheet discharged from the sheet discharge portion is thrust. The stopper has a support portion, a restricting portion, and an urging mechanism. The restricting portion is supported pivotally on a pivot shaft on the support portion, and is arranged either in a retracted position to lie flat substantially horizontally along the sheet stacking surface or in a restricting position to stand upright substantially vertically to the sheet stacking surface. The urging mechanism urges the restricting portion, when in retracted position, in a direction from restricting position to retracted position and, when in restricting position, in a direction from retracted position to restricting position.

摘要： A sheet feeder includes a sheet platen, a pickup roller, a feeding roller, a regulating portion, a driving mechanism, a feeding control unit, a sheet sensor, and a determination processing unit. The feeding control unit executes a feeding operation by rotationally driving the pickup roller and the feeding roller in a state where the regulating portion is located at a retreating position. The sheet sensor is located at a downstream side in the feeding direction of the feeding roller. The determination processing unit determines whether the sheet feeding has succeeded or not based on a signal from the sheet sensor. After a start of the feeding operation, when the determination processing unit determines that the sheet feeding has failed, the feeding control unit once moves the regulating portion located at the retreating position to the abutting position and then executes the feeding operation again.

摘要： A base portion includes a cam surface formed around a support pin. A turning portion includes: a slide member provided movably in directions toward and away from the support pin; and a coil spring urging the slide member. The slide member is designed to slide on the cam surface while turning, together with an openable body, about the support pin. The cam surface includes a first sliding surface, a second sliding surface, and a third sliding surface. The first sliding surface presses the slide member back in a direction of closing of the openable body. The second sliding surface presses the slide member back in a direction of opening of the openable body. The third sliding surface presses the slide member back in the direction of closing of the openable body.
