In the invention described, an actuating solenoid on one side of a printer wall connects to a pawl by a lever component. The lever has a pawl-actuating post extending through a wall window so that it may interface with a flared slot on the clutch's pawl. By extending the post through the wall window, space is saved when the printer door is closed because the solenoid does not need to be on the inside of the wall.

An image reading apparatus includes a feeding roller that includes a first roller and a second roller provided at an interval in a width direction intersecting a medium feeding direction, and feeds a sheet from a placing section; and a skew detection section that detects skew of the sheet fed from the feeding roller. Skew is corrected by giving a difference between a rotation speed of the first roller and a rotation speed of the second roller with respect to at least one of the relevant sheet detected by the skew detection section and subsequent sheets fed following the relevant sheet based on a skew amount in the sheet.

A sheet feeding apparatus includes a sheet stacker to stack at least one sheet; a sheet feed roller disposed at one side of the sheet stacker and to feed a sheet fed from the sheet stacker; a multi-feed prevention roller disposed to face the sheet feed roller and to prevent multi-feed of the sheet fed from the sheet stacker; a magnetic torque limiter disposed coaxially with the multi-feed prevention roller; a hall sensor disposed at one side of the magnetic torque limiter and to detect rotation of the magnetic torque limiter; and a controller configured to rotate the sheet feed roller in a state in which the sheet feed roller and the multi-feed prevention roller are in contact with each other without a sheet and to identify a lifetime of the multi-feed prevention roller by using a signal output from the hall sensor.

The invention relates to a switch assembly for a device for handling value documents, comprising a shaft (110) which is rotationally fixed to a switch body (120), said switch body (120) being rotatable about the longitudinal axis of the shaft (110) between a first switch body position (PI) and a second switch body position (P2). The switch assembly additionally comprises a switch lever (130, 131), said shaft (110) being rotatable about its longitudinal axis by means of the switch lever (130, 131), and a solenoid (200) which comprises an armature (210). The solenoid (200) can be actuated such that the armature (210) can be moved between a first armature position (AI) and a second armature position (A2). The switch lever (130, 131) is in engagement with the armature (210) such that the switch lever (130, 131) rotates about the longitudinal axis of the shaft (110) by means of the movement of the armature.

A sheet conveying apparatus includes a transmitting mechanism, a movable member, and a control portion to input a signal having first and second levels. The transmitting mechanism transmits driving force and includes a spring clutch and an electromagnetic clutch. The driving force pivotally moves the movable member. The spring clutch idles by a slackness of a spring when the rotation in a second direction is inputted to the transmitting mechanism and the movable member is regulated from pivoting at a predetermined position. The control portion inputs the signal to the transmitting mechanism such that the state electromagnetic clutch state changes the engagement state to the disengagement state through an intermediary state gradually varying a length of time where the signal of the first level is inputted into the electromagnetic clutch after the movable member reaches the predetermined position by inputting the rotation in the second direction to the transmitting mechanism.

A sheet conveyor includes a separation roller, a retard roller forming a nip with the separation roller, and a load application device configured to apply a load to the retard roller. The load application device includes a motor, a first drive train, a second torque limiter isolated from the first drive train, and a controller. The first drive train includes a plurality of gears for transmitting a driving force from the motor to the retard roller, a first torque limiter, and a clutch disposed between the motor and the first torque limiter. The second torque limiter is configured to communicate with the retard roller. The controller is configured to, during conveyance of a sheet, control the clutch to allow transmission of the driving force from the motor for a predetermined time period and to interrupt transmission of the driving force from the motor after expiration of the predetermined time period.

An image reading apparatus includes a feeding roller that includes a first roller and a second roller provided at an interval in a width direction intersecting a medium feeding direction, and feeds a sheet from a placing section; and a skew detection section that detects skew of the sheet fed from the feeding roller. Skew is corrected by giving a difference between a rotation speed of the first roller and a rotation speed of the second roller with respect to at least one of the relevant sheet detected by the skew detection section and subsequent sheets fed following the relevant sheet based on a skew amount in the sheet.

A medium conveying apparatus includes a medium tray, a feed roller to feed media placed on the medium tray in order from the lower side, a brake roller located to face the feed roller, a torque limiter to control a load applied to the brake roller, and a changing member to change a limit value of a torque of the torque limiter according to a height of the media placed on the medium tray.

A medium conveying apparatus includes a driving force transmitting mechanism to transmit a driving force from a first motor to a brake roller and a pair of conveyance rollers located on the downstream side of the brake roller, and a processor to rotate the first motor forward to control so that a medium separated by the brake roller is conveyed by the pair of conveyance rollers, in a separation mode. The processor rotates the first motor backward to perform a feed operation by the brake roller and rotate the pair of conveyance rollers backward until a front edge of the medium passes through a position of the brake roller, and rotates the first motor forward to control so that the medium is conveyed by the pair of conveyance rollers after the front edge of the medium passes through the position of the brake roller, in a non-separation mode.

A medium conveying apparatus includes a setting member to set a torque limiter that defines a maximum torque applied to a brake roller to a first torque limiter or a second torque limiter, a unit including the first torque limiter, the second torque limiter and the brake roller, and a transmission member to transmit a drive force to the first torque limiter. The unit is swingably supported so that a predetermined force acts on the brake roller in a direction away from the feed roller when the driving force is transmitted. A force in a direction in which the brake roller presses the feed roller when the second torque limiter defines the maximum torque applied to the brake roller is greater than the force in the direction in which the brake roller presses the feed roller when the first torque limiter defines the maximum torque applied to the brake roller.
