A sheet transport device includes a transport roller, a drive source, and a gear train The transport roller transports a sheet. The gear train transmits rotating force from the drive source to the transport roller. The gear train includes a movable gear and a leaf spring. The movable gear is configured to move between a normal position where transmission of the rotating force to the transport roller is enabled, and a disengaged position where the transmission of the rotating force to the transport roller is interrupted, and also to move in an axial direction, and includes a helical gear that generates force to axially move in one direction, when the movable gear moves from the normal position to the disengaged position. The leaf spring buffers the movement of the movable gear in the one direction.

A presentation device for presenting a ticket from a printer includes first and second reels, a ticket holder and a housing component. In operation, the first reel contacts a first side of the ticket, and the second reel contacts a second side of the ticket opposite to where the first reel contacts the first side of the ticket. As the ticket advances from the presentation device, gravity pushes the ticket down onto the ticket holder, which is a reel. The first reel, the second reel and the ticket holder are secured in the housing component. The housing component is pivotable about a rotating axis and has a supporting notch that supports the second reel. The supporting notch has a first guide edge surface that faces away from the rotating axis, a second guide edge surface, and a trough between the first guide edge surface and the second guide edge surface.

A sheet conveyance device includes a first conveyance member, and a drive transmission mechanism. The first conveyance member is configured to convey a sheet toward a second conveyance member. The drive transmission mechanism is configured to transmit a driving force of a driving source to the first conveyance member. The drive transmission mechanism includes a first drive transmitter and a second drive transmitter disposed coaxially with the first drive transmitter. The driving force is transmitted from the first drive transmitter to the second drive transmitter. The second drive transmitter is rotatable relative to the first drive transmitter within at least a predetermined angular range.

A feeding roller structure includes a fastening frame, a transmission component, a transmission roller and a floating coupler. The transmission component is assembled in the fastening frame. The transmission component includes a drive shaft transversely pivoted to two sides of the fastening frame. The transmission roller is concentrically arranged around the drive shaft. The floating coupler is mounted to the fastening frame. The floating coupler is coupled between the drive shaft and the transmission roller. Two opposite ends of the floating coupler are adjacent to and spaced from the two sides of the fastening frame to form two gaps. Each gap is formed between one end of the floating coupler and one side of the fastening frame. The two gaps limit an angular displacement of the floating coupler.

A method of adhering a tape for a rechargeable battery is provided. The method includes contacting one surface of a rechargeable battery with an attachment surface of a tape via an attachment roller interposed therebetween, rotating the attachment roller in a first direction to attach the tape to one surface of the rechargeable battery, and rotating the attachment roller in a second direction opposite the first direction to cut the tape.

A driving force transmitting apparatus includes first and second planetary gear units and switching and urging members. The first planetary gear unit includes a first mesh gear and a first locked gear provided with first locked portions. The second planetary gear unit includes a second locked gear provided with second locked portions, and a second mesh gear meshing with the first mesh gear. The switching member includes first and second locking portions and can move to (i) a first stop position at which the first locking portion stop the first locked gear, and, urged by the urging member, (ii) a second stop position at which the second locking portion stops the second locked gear. An interval between the second locked portions in a rotational direction of the second locked gear is larger than an interval between the first locked portions in a rotational direction of the first locked gear.

A sheet transport device includes a transport roller, a drive source, and a gear train. The transport roller transports a sheet. The gear train transmits rotating force from the drive source to the transport roller. The gear train includes a movable gear and a leaf spring. The movable gear is configured to move between a normal position where transmission of the rotating force to the transport roller is enabled, and a disengaged position where the transmission of the rotating force to the transport roller is interrupted, and also to move in an axial direction, and includes a helical gear that generates force to axially move in one direction, when the movable gear moves from the normal position to the disengaged position. The leaf spring buffers the movement of the movable gear in the one direction.

An automatic document feeder includes a media path to route media through the automatic document feeder, a plurality of opposing roller pairs to route media along the media path, and a serpentine belt drive system to drive a roller of each of the opposing roller pairs.

A rotating device includes: an opening-closing portion supported so as to be openable and closable with respect to a support body; a drive unit provided on the support body; a first rotating body provided on the support body and rotated by a drive force of the drive unit; a driven portion provided in the opening-closing portion; a second rotating body provided in the opening-closing portion, rotated by a transmitted rotational force, and transmitting the rotational force to the driven portion; and an annular body formed in an annular shape, wound around the first rotating body and the second rotating body, maintaining the winding state in both an open state and a closed state of the opening-closing portion, and transmitting the rotational force of the first rotating body to the second rotating body.

A sheet dispenser for a dryer appliance includes a housing that defines a storage volume and an outlet. The storage volume is configured for receipt of a plurality of dryer sheets for dispensing. A roller is mounted to the housing within the storage volume. A motor is coupled to the roller such that the motor is operable to rotate the roller. The roller is configured to urge the plurality of dryer sheets in the storage volume through the outlet of the housing when the motor rotates the roller.
