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.

The present disclosure provides a drive transmission apparatus capable of reducing vibration of rotating member. The apparatus includes a shaft, a pin, and a rotating member. The rotating member is engaged with the shaft by the pin and rotates with the shaft. A protruded portion is provided on one of an outer circumferential surface of the shaft and an inner circumferential surface of the rotating member. The rotating member is attached to the shaft with the protruded portion in pressure contact with another one of the outer circumferential surface of the shaft and the inner circumferential surface of the rotating member, so that swinging of the rotating member around the pin is restricted.

A sheet feeding device includes: a feeding unit that is provided to be movable in a forward-backward direction to move forward or backward relative to a sheet placing unit on which a sheet is placed, and feeds the sheet; a moving unit that moves the feeding unit in the forward-backward direction; a contact unit that is provided to be movable, with which the sheet placed on the sheet placing unit is brought into contact; a limitation unit that limits movement of the contact unit; and a releasing unit that, when the moving unit moves the feeding unit in a direction away from the sheet placing unit, with the movement of the feeding unit, releases limitation on the movement of the contact unit by the limitation unit.

The present invention relates to the field of petroleum extraction equipment, and discloses a coiled tubing reel and a coiled tubing vehicle. The coiled tubing reel comprises a reel body assembly configured to wind a coiled tubing and a driving component configured to drive the reel body assembly, wherein, the reel body assembly comprises a reel body, a reel shaft, a transmission gear, and a first bearing block and a second bearing block that are oppositely arranged and spaced from each other, wherein the reel body is fixedly fitted on the reel shaft, the two ends of the reel shaft are rotatably arranged on the first bearing block and the second bearing block respectively, the transmission gear is fixed with respect to the reel shaft to drive the reel shaft to rotate, the driving component is fixedly arranged on the first bearing block and at least partially disposed inside the reel body, and the driving component comprises a driving gear that is engaged with the transmission gear. The coiled tubing reel and coiled tubing vehicle provided in the present invention can increase the coiled tubing winding capacity, provide high transmission torque, and operate smoothly and steadily at a low speed, while meeting the requirement for transportation dimension.

A drive transmission mechanism of a recording apparatus includes a first transmission member that is rotated by a drive force from a drive source, a second transmission member by the drive force from the first transmission member so as to be rotated in a first direction and in a second direction, a third transmission member by the drive force from the second transmission member so as to be rotated, and a support member having a first region that receives a first pressing force from the second transmission member rotated in the first direction and a second region that receives a second pressing force from the second transmission member rotated in the second direction. The support member has grooves disposed on an upstream side of the first region in the first direction and on an upstream side of the second region in the second direction.

A medium conveying apparatus includes a torque limiter provided on a rotation axis of the separation roller, a unit including a first gear, a second gear provided on the rotation axis, and a third gear provided between the first gear and the second gear. The separation roller is pressed toward a feed roller side by a force generated by the torque limiter. The first gear rotates in a direction for generating a force for separating the separation roller from the feed roller. The third gear is a two-stage gear. The number of teeth of a gear on the second gear side of the third gear is more than the number of teeth of a gear on the first gear side of the third gear.

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.

Apparatus and associated methods relate to a handheld power-dispensing tape dispenser having a center of gravity forward of a user's hand. In an illustrative example, a tape dispenser may, for example, include a housing having a handle configured to be held by a human hand. A first roller body may, for example, be rotatably coupled to the housing to rotate about a first axis. A motor may, for example, be disposed in the first roller body. An actuator may, for example, be configured such that, in response to operation of the actuator by a user, the motor induces rotation of the first roller body about the first axis. A second roller body may, for example, be rotatably coupled to the housing and configured to rotate about a second axis substantially parallel to the first axis. Various implementations may advantageously increase stability and/or reduce operator fatigue during taping operations.
