Abstract: A first opposing portion of the coupling includes first ratchet hook and a second opposing portion of the second rotary body includes a second ratchet hook. One of the third opposing portion of the coupling and the fourth opposing portion of the first rotary body has a cam on an end face thereof and the other one has a cam face on an end face thereof. 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 provided on a portion other than the cam or the cam face of the 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 portion other than the cam or the cam face of the end face of the other one of the third opposing portion and the fourth opposing portion while the transmission of torque is turned off.

Abstract: A sheet feeder includes a delivery roller, a supply roller, a separating member, a driving source, a first drive transmission mechanism, a second drive transmission mechanism, and a controller. The first drive transmission mechanism transmits the rotary drive power in the first direction to the delivery roller in a first drive transmission time from the start of driving of the driving source. The second drive transmission mechanism transmits the rotary drive power in the first direction to the supply roller in a second drive transmission time from the start of driving of the driving source. The second drive transmission period of the second drive transmission mechanism is longer than the first drive transmission period of the first drive transmission mechanism. When the control starts driving the driving source, the supply roller starts to rotate in the first direction after the delivery roller starts to rotate in the first direction.

Abstract: A document sheet transportation device includes a feeding portion which feeds a document sheet from a document sheet placement portion toward a document sheet transportation path. The feeding portion includes a holder, a feeding member, a supporting body supported by the holder, a rotatable stopper member having a contact end portion allowed to contact a front end of a document sheet, and a biasing member which applies a biasing force to the stopper member. The stopper member is allowed to change a position among a first position in which the contact end portion contacts the front end of the document sheet, a second position which allows feeding of the document sheet by the feeding member, and a third position which is rotated in the first rotating direction from the second position. The biasing member applies the biasing force to the stopper member in a reverse second rotating direction.

Abstract: 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.

Abstract: A document pressing unit is openable with respect to an apparatus body including a placement portion on which a document is placed, and is configured to press the document from above. The document pressing unit includes a body frame, a pair of hinge units, a pair of metal fixing members, and fastening screws. The body frame is able to press the document. The hinge units respectively include hinge legs mounted on the apparatus body, and are mounted with a certain distance in a left-right direction on a rear end of the body frame to openably support the body frame with respect to the apparatus body. The fixing members fix the hinge units to the body frame, respectively. The fastening screws fasten the fixing member and the hinge unit through the body frame so that the fixing member and the hinge unit sandwich the body frame in an up-down direction.

Abstract: 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.

Abstract: A sheet feeder includes a sheet placing portion, a feeding member, a supporting body, a driver, an electromagnetic clutch and a retraction controller. The supporting body is capable of changing a posture between a sheet feeding posture of the feeding member and a retracting posture for retracting the feeding member. The electromagnetic clutch is capable of changing a state between an engaged state in which a drive force is transmitted to the supporting body and a disengaged state in which the drive force is not transmitted to the supporting body. The retraction controller stops the output of a drive force after the electromagnetic clutch is set in the engaged state and the supporting body is set to the retracting posture by the drive force, and sets the electromagnetic clutch in the disengaged state when an engagement keeping time elapses after the output of the drive force is stopped.
