The present invention relates to a web film movement compensating device for a web film movement compensation between continuous forward movement section and intermittent forward movement section comprising two guide rollers (1, 2) rotating freely in stationary positions between a continuous driving device (5) and an intermittent driving device (6), two compensation rollers (3, 4) rotating freely on two respective pivoting arms (7, 8) oscillating about pivot shafts (11, 12), an elastic element (9) connected to one of the pivoting arms to actuate the corresponding compensation roller to move away from the guide rollers, and a movement transmission mechanism including lever arms and transmission rods (13, 14, 15) transmitting an oscillating movement from one of the pivoting arms (7, 8) to the other. A web film (50) moved by the driving devices is supported on the guide rollers (1, 2) and on the compensation rollers (3, 4) forming a meander.

A paper separation mechanism, comprising a separation roller assembly having a separation roller, a torque limiter connected to the separation roller, and a separation gear arranged between the separation roller and the torque limiter; a transmission gear assembly having a first transmission gear which is able to mesh or separate with the separation gear, a second transmission gear meshed with the first transmission gear, and a connecting part connected the first transmission gear and the second transmission gear; and a motor connected to the transmission gear assembly for applying forward or reverse torque; wherein when the motor is applying the forward torque, the connecting part rotates forward to mesh the first transmission gear with the separation gear; and when the motor is applying the reverse torque, the connecting part rotates reverse to separate the first transmission gear with the separation gear.

A drive mechanism that drives a rotator to rotate includes a main motor, an assist motor, and processing circuitry. The main motor drives the rotator. The assist motor drives the rotator and assists a drive of the rotator by the main motor. The processing circuitry controls a speed of the main motor so that a rotational speed of the rotator is constant, and controls a motor voltage of the assist motor so that the motor voltage of the assist motor changes according to a change in a motor current of the main motor.

A multi-feed detection device includes a transmission circuit substrate on which an ultrasonic transmitter transmitting an ultrasonic wave is installed, and an ultrasonic receiver receiving the ultrasonic wave. The ultrasonic transmitter transmits the ultrasonic wave in a direction intersecting a thickness direction of the transmission circuit substrate and at least one of the ultrasonic transmitter and the ultrasonic receiver has a plurality of ultrasonic elements.

A recording device includes a recording unit configured to record on a medium, a transportation unit configured to transport the medium, a driving member, a plurality of gears configured to transmit a driving force of the driving member, and a sound absorber having an opening and a hollow space in communication with the opening. The sound absorber is located between a side end of the medium being transported by the transportation unit and the plurality of gears.

Provided is a circulation-type paper sheet storage unit equipped with circulation units in a casing, enabling to swiftly take measures and perform recovery processing on the user side when the circulation unit malfunctions. The paper sheet storage unit includes circulation units (100 and 200) that are accommodated in a casing 60 to receive paper sheets transported into the casing by operating upon reception of a drive force from a motor and feed paper sheets stored therein to outside of the casing. The casing includes guide members 620 that serve as a guide at the time of attaching or detaching the circulation unit with respect to the casing, and the circulation unit includes guided members (655A, 675A, 655B, and 675B) which respectively detachably engage with the guide member, and are guided to an installation completion position along the guide members in an engaged state.

In an example, a load stop may comprise a stop paddle, a paddle link, a swingarm engaged with a motive element, and a cam gear to engage the swingarm with the paddle link. The paddle link may move the stop paddle from a locked position, to a gathering position, and to a stowed position. The swingarm may transfer the motion of the motive element to the cam gear such that the cam gear is to move in a first direction, the cam gear to drive the paddle link to move the stop paddle from the locked position, to the gathering position, and to the stowed position when the motive element moves in a first drive direction, and the swingarm moves the cam gear in the first direction.

A sheet conveyer having a sheet tray, a tray-driving mechanism, a conveyance guide, a feed roller, a separator, a conveyer, a conveyer-driving mechanism, a controller, and a sheet sensor to detect sheets on the sheet tray, is provided. The conveyer-driving mechanism includes a transmission-active portion and a transmission-passive portion. A conveying velocity to convey the sheets by the conveyer is higher than a conveying velocity to convey the sheets by the feed roller and the separator. The transmission-active portion and the transmission-passive portion are rotatable about a transmission axis. The transmission-passive portion rotates passively by being pushed by the transmission-active portion. After the sheet sensor detects absence of the sheets, and before the transmission-passive portion starts rotating passively, the controller conducts a specific action to move the sheet tray downward by controlling the tray-driving mechanism.

A recording device includes a first transportation path along which a medium is transported, a recording unit configured to record on the medium on the first transportation path, a second transportation path branching from the first transportation path, a flap located at the junction and configured to be moved to a first position to open the first transportation path and to a second position to close the first transportation path, and a driving section. After the medium passes the junction, the flap is positioned at the second position to come in contact with the medium traveling upstream along the first transportation path and guide the medium to the second transportation path. The flap is moved to the first position by a driving force of the driving section.

It is aimed to downsize of the entire apparatus without setting the swing angle of a swing member to be unnecessarily large. A pickup roller, which is for feeding a document disposed on a feeding tray, is supported by a pickup arm that is swingable about a rotation shaft. Depending on the rotational direction of the rotation axis, the pickup arm swings between the first position, in which the pickup roller is in contact with the document on the feeding tray, and the second position, in which the pickup roller is above and not in contact with the feeding tray. An arm member is rotated by rotation of the rotation axis after the pickup arm swings to the second position.
