A sheet conveying device includes a sheet supporting portion, a first lever pivotable by contact with a sheet supported by the sheet supporting portion, a hook movable together with the first lever, a first cam configured to, when engaging the hook, stop rotating in a rotation direction of the first cam, a spring configured to urge the first cam in a rotation direction, a sector gear rotatable together with the first cam, a drive gear configured to, when engaging the sector gear, transmit a drive force to the sector gear, a feed roller rotatable in contact with the sheet, and a drive mechanism configured to receive a drive force from the sector gear and move one of the feed roller and the sheet supporting portion toward the other of the feed roller and the sheet supporting portion, to increase contact pressure between the feed roller and the sheet.

A sheet conveyance apparatus is configured to interlock a first transmission mechanism and a second transmission mechanism such that the second transmission mechanism switches a rotational driving direction of a reverse rotary member between a normal rotation direction and a reverse rotation direction with a delay with respect to the first transmission mechanism starting transmission of a rotational driving force such that a guide member pivots between a first pivot position and a second pivot position.

A bidirectional media supporting system includes a first and second rollers configured to rotate to feed media in forward and reverse feed modes; a first clutch bearing set, and a second clutch bearing set configured to engage with the first clutch bearing set; and a gear transmission assembly configured to transfer a driving force from the first roller to the second roller. A method for reversing direction of printing media includes advancing media while maintaining a rotational speed of a platen roller assembly above that of a feeding roller assembly; receiving a signal to reverse the direction of advancing media; and adjusting operation by reversing a direction of rotation of a transmission gear coupled to the feeding and platen roller assemblies, and by rotating the roller assemblies in an opposite direction, while maintaining the rotational speed of the platen roller assembly below that of the feeding roller assembly.

A banknote storage unit comprising: a first tape reel banknote storage device; a second tape reel banknote storage device; and a drive transmission means pivotable between engagement with said first tape reel banknote storage device and engagement with said second tape reel banknote storage device.

A thermal transfer apparatus is disclosed. The thermal transfer apparatus has a heating roller movable between a film contact position and a retracted position. The thermal transfer apparatus also includes a nip roller positioned opposed to the heating roller when the heating roller is in the film contact position. The heating roller is moved from the film contact position to the retracted position in response to opening of the cover and is not moved from the retracted position to the film contact position during closing of the cover.

An electronic dispenser comprising a housing; a feed roller rotatably mounted within the housing; a motor operable to drive rotation of the feed roller, and wherein the motor is at least partially within the feed roller; and wherein actuation of the motor results in a noise level, external to the housing, of less than 53 A-weighted decibels.

A clutch device includes a sector gear, a cam, an electromagnetic solenoid, a first lever, a second lever, a first spring, and a second spring. The cam includes a slide portion. The first lever engages with the electromagnetic solenoid and includes a first restricting portion. The second lever includes a hook and a second restricting portion. The first spring is configured to urge the second lever in a direction in which the first restricting portion and the second restricting portion contact each other. The second spring is configured to, when the electromagnetic solenoid is in a de-energized state, move the first lever. The slide portion of the cam has a surface configured to, when the electromagnetic solenoid is in an energized state, press the hook in a direction opposite to an urging direction of the first spring such that the second restricting portion is separated from the first restricting portion.

A webbing take-up device that includes: a cut-off section that cuts off transmission of rotation load along a rotation force transmission route from a second rotation force transmission mechanism to a spool via a first rotation force transmission mechanism due to the rotation load in a pull-out direction becoming a predetermined value or greater; and a resistance section that resists the rotation load during transmission of the rotation load, and that suppresses transmission of the rotation load along the rotation force transmission route in a case in which the rotation load is less than the predetermined value.

A bidirectional media supporting system includes a first and second rollers configured to rotate to feed media in forward and reverse feed modes; a first clutch bearing set, and a second clutch bearing set configured to engage with the first clutch bearing set; and a gear transmission assembly configured to transfer a driving force from the first roller to the second roller. A method for reversing direction of printing media includes advancing media while maintaining a rotational speed of a platen roller assembly above that of a feeding roller assembly; receiving a signal to reverse the direction of advancing media; and adjusting operation by reversing a direction of rotation of a transmission gear coupled to the feeding and platen roller assemblies, and by rotating the roller assemblies in an opposite direction, while maintaining the rotational speed of the platen roller assembly below that of the feeding roller assembly.

A clutch device includes a drive transmitting shaft; a driving-side engaging member; and a driven-side engaging member. A driving force is transmitted from the driving-side engaging member to the driven-side engaging member. The driving-side engaging member has a driving-side clutch tooth, and the driven-side engaging member has a driven-side clutch tooth capable of being engaged with and released from the driving-side clutch tooth. The driving-side clutch tooth and the driven-side clutch tooth have drive transmitting surfaces inclined so as to axially attracting each other in engagement with each other. At least one of the driving-side clutch tooth and the driven-side clutch tooth has a functional surface on a free end side relative to the drive transmitting surface with respect to the engaging direction. The functional surface is inclined so as to axially separating from a surface of the other clutch tooth in engagement therewith.
