A recording device includes a recoding unit, a discharge rollerunit, a medium receiving tray, a motor serving as a power source of the discharge roller, a power transmission unitunit that is configured to switch between a power transmission state in which power of the motor is transmitted from the motor to the medium receiving tray, and a power non-transmission state in which the power of the motor is not transmitted from the motor to the medium receiving tray, and a restriction unitunit that is configured to switch between a restriction state in which the restriction unit restricts displacement of the medium receiving tray when the power transmission unit is in the power non-transmission state, and a non-restriction state in which the the restriction unit does not restrict the displacement of the medium receiving tray when the power transmission unit is in the power transmission state.

A remotely controlled, tethered vehicle system is comprised of a communication network interface, a system command and control module, a power source, a tether cable spooling apparatus and a remotely controlled vehicle that is tethered to the communication, control and power source by a cable that is controlled to be dispensed from or retracted into the spooling apparatus. The spooling apparatus has a spooling mechanism that is controlled to move the cable into and out of the spooling apparatus without using a slip ring device.

A medium supporting device including a support part configured to support a roll body on which a sheet shaped medium is wound, a shaft serving as a rotary axis of the roll body and secured with the support part, and a driver configured to rotate the roll body supported by the support part. The shaft is secured to the support part by using a metal plate having a flat surface provided with an insertion hole, the insertion hole being a hole into which the shaft is inserted. An outer circumference part of the metal plate is restricted from moving in a rotation direction of the roll body relative to an inner circumference part of the support part.

A drive transferring unit includes a first roller, a second roller, a first clutch, a second clutch, a transferring section, and a control section. The first roller includes a first shaft section. The second roller includes a second shaft section. The first clutch switches between enabling transfer of a driving force to the first shaft section and interrupting transfer thereof. The second clutch switches between enabling transfer of the driving force to the second shaft section and interrupting transfer thereof. The transferring section transfers the driving force from one of the first roller and the second roller to the other. The control section selects between first control in which the first clutch is in the on state and the second clutch is in the off state and second control in which the second clutch is in the on state and the first clutch is in the off state.

A sheet conveying device includes: a housing in which a conveying path of a sheet is formed; a roller configured to convey the sheet by rotation; a motor arranged inside of the housing; a drive transmitter configured to transmit a drive force of the motor to the roller; a movement member including a guide part configured to guide the sheet and at least a part of the drive transmitter, the movement member being movable to a first position closing the inside of the housing with respect to an outside of the housing and a second position different from the first position; and a dust proofing part attached to a position filling a gap between the movement member located in the first position and the housing.

A medium feeding apparatus includes a feeding roller, a separation roller which nips a medium between the separation roller and the feeding roller to separate the medium and to which a driving torque is applied by a driving source in a second rotation direction that is opposite to a first rotation direction in which the medium is fed to a downstream side, and a torque limiter that causes the separation roller to idle in the first rotation direction when a rotational torque applied to the separation roller in the first rotation direction exceeds a limit torque that is a predetermined upper torque limit, in which separation setting including a pressing load of the separation roller, a rotational speed of the separation roller, and the limit torque is changeable according to condition of feeding.

An apparatus for separating blanks from a stack of blanks includes a drive shaft that interacts with the drive unit and that drives a belt arranged in a cassette. The drive shaft is neither enclosed nor carried by the cassette. A reversible securing means secures the cassette to a carrying structure of the apparatus in a detachable manner in such a way that the cassette can be repeatedly removed or detached and then refitted.

The invention relates to a brake device for producing a brake torque counter to a torque acting on a rotatably supported member, wherein the brake device has: at least one toothed brake ring which is mechanically actively connected to the rotatably supported or supportable member, a plurality of bending-resistant brake levers which each have at a first lever end at least one stop which engages in the tooth arrangement of the brake ring and which are each rotatably supported on a second lever end opposite the first lever end, wherein each brake lever is connected to a force element for applying a brake force in such a manner that, as a result of the brake force via the stop of the respective brake lever which is in engagement with the tooth arrangement of the brake ring, a brake torque is produced on the brake ring tangentially counter to the active direction of the torque in order to apply a brake torque to the rotatably supported or supportable member, wherein the brake levers are arranged with respect to the toothed brake ring in such a manner that, during a rollover of a brake lever, in which the stop of the respective brake lever engages in a subsequent tooth flank of the tooth arrangement, all remaining brake levers with their respective stops remain in engagement with their respective tooth flank of the tooth arrangement.

A medium conveying apparatus includes a medium tray, a feed roller to feed a medium placed on the medium tray, a brake roller facing the feed roller, a pressing member to press the brake roller to the feed roller side, a processor to detect media multi-feed, and control the feed roller and the brake roller in such a way that the medium is reset to the medium tray when the media multi-feed of media is detected. The processor controls the pressing member in such a way that a pressing force of the brake roller when resetting the medium to the medium tray is greater than a pressing force of the brake roller when feeding the medium.

A printer includes a front cover to open and close an opening portion of a front surface of a box casing and a housing that is provided in the casing and in which roll paper held in a roll paper holder is housed through the opening portion. The roll paper holder includes flanges that are disposed in both end portions of the roll paper, respectively, and the flanges project from the opening portion when the roll paper is housed in the housing.
