A sheet feeding device includes a tray, a feeding member, a conveying member, a separation member, a transmission unit, and a biasing member. The separation member abuts the conveying member and separates a single sheet from sheets fed by the feeding member. The transmission unit includes first and second portions respectively having first and second transmission surfaces. Where the first and second transmission surfaces abut each other, the first portion drives the second portion that drives the feeding member. The biasing member biases either of the first and second portions so that the first and second transmission surfaces move away from each other. The conveying member is driven in a state where the separation member abuts the conveying member and the feeding member abuts the sheet stacked on the tray and is stopped. Thereafter, the first and second transmission surfaces abut each other, and the feeding member is driven.

A sheet conveyance apparatus comprises: a first conveyance roller configured to convey a sheet; a second conveyance roller, arranged downstream of the first conveyance roller in the conveyance direction in which the sheet is conveyed, configured to convey the sheet; a first conveyance path configured to guide the sheet from the first conveyance roller to the second conveyance roller; a second conveyance path, which is branched from the first conveyance path between the first conveyance roller and the second conveyance roller to guide the sheet, the second conveyance path having a bent portion; a third conveyance roller configured to convey the sheet guided by the second conveyance path; a first motor configured to drive the third conveyance roller; a second motor; a first transmission mechanism configured to transmit a driving force of the second motor to the second conveyance roller.

Subsequent to completion of printing on a current media sheet, a pick transmission of the printing device linking a motor of the printing device to a pick roller of the printing device is engaged to load a next media sheet via the motor driving the pick roller. While the next media sheet is being loaded due to the motor driving the pick roller, the current media sheet is ejected via the motor driving an eject roller of the printing device.

In the webbing winding device, the rotation of the output shaft of the motor is transmitted to the spool via the first gear train. In this state, when the rotation speed of the spool decreases and the rotation of the slider base of the first clutch decreases, the coupling pawl of the second clutch is pressed by the slider provided on the slider base to mesh with the ratchet gear, and the rotation of the output shaft of the motor is transmitted to the spool via the second gear train.

A drive transmitting device includes a first gear; a second gear in engagement with the first gear; wherein a first tooth which is at least one of teeth of the first gear has a tooth surface contacting a tooth of the second gear, wherein the tooth surface has such a shape that a contact point of the first tooth of the first gear to the tooth of the second gear is in a region of a first gear side with respect to a line of action which is formed by movement of a contact point between a tooth of the second gear and a second tooth of the first gear immediately before the first tooth with respect to a rotational moving direction of the first gear.

A sheet conveyance apparatus includes a drive source, a conveyance portion, a transmission mechanism configured to switch between a first state and a second state, a load detection portion configured to detect a load acting on the drive source, and a control portion configured to control the drive source and the transmission mechanism. The control portion is configured to change, on a basis of a detection result of the load detection portion, a timing in the conveyance operation at which a control signal for switching the transmission mechanism from the first state to the second state is issued, the timing being changed in accordance with a delay time from when the control signal is issued to when change in the load corresponding to the switching of the transmission mechanism from the first state to the second state appears.

A driving force transmission device includes a rotating body that is rotated by receiving a driving force, a control unit that controls rotation of the other rotating part by being switched between a connection state where the control unit is connected to the other rotating part and a separation state where the control unit is separated from the other rotating part as states of the control unit with respect to the other rotating part, and an operation unit that is operated by receiving a force output from the rotating body and includes a contact mechanism to be in contact with the control unit, the contact mechanism being moved by the force output from the rotating body to operate the control unit and the contact mechanism then being separated from the control unit.

An apparatus, system and method for providing an automated contact cutter. The contact cutter includes a contact reel holder for holding therein a bandoleer comprising a plurality of stamped contacts; at least an inlet roller comprising an inlet pin, a turn roller, and a receiving roller mechanically connected by at least one motor drive belt to a drive motor, wherein the inlet roller is capable of receiving an end portion of the bandoleer onto the inlet pin for loading; a cutter between the turn roller and the receiving roller that is capable of cutting ones of the stamped contacts from the bandoleer for picking by a pick and place robot; and a comb capable of combing at least the bandoleer and cut and partially cut ones of the stamped contacts.

A conveyance rotating body is rotatably supported by a support member. A second rotational axis at a rotation center of a driven transmission member is disposed at a position different from a position of a first rotational axis. When a feeding unit is attached to a sheet feeding apparatus, a drive transmission member and the driven transmission member engage with each other. When a driving force is transmitted from the drive transmission member to the driven transmission member, the feeding unit receives a force in an attachment direction of the feeding unit and is positioned with respect to the sheet feeding apparatus.

A sheet conveying apparatus may comprise a first conveying roller configured to convey a sheet and a second conveying roller disposed on a downstream side of the first conveying roller in a conveyance direction of the sheet. In a case where the second conveying roller rotates at a first speed by a driving force being transmitted to the second conveying roller, the first conveying roller rotates by being driven with respect to the second conveying roller. In a case where the second conveying roller rotates at a second speed faster than the first speed by the driving force being transmitted to the second conveying roller, the first conveying roller rotates at the second speed.
