A winding apparatus includes a winding core unit onto which a continuous medium is to be wound, the winding core unit having a notched portion having a shape in which a part of the winding core unit in a circumferential direction is cut out as viewed in an extending direction of the winding core unit, and a notch complementing unit to be detacheably inserted into the notched portion from one end portion side in the extending direction of the winding core unit, the notch complementing unit being configured to complement the notched portion.

In a manufacturing process of a battery or a circuit board, or a printing process, there is a case where a long sheet material is conveyed from an unwinding unit to a winding unit. One object of the present disclosure is to provide a technique capable of preventing the long sheet material from being rubbed by a roller when the material is conveyed. The present disclosure relates to a conveyor adapted for a battery manufacturing process. The conveyor comprises a roller configured to convey a long sheet material, a shaft through the roller; a bearing installed between the roller and the shaft, and a driver configured to rotate the shaft in the same direction as a rotating direction of the roller conveying the long sheet material.

A rewinding machine winds a web material into a log about a core. The web material to be wound is directed about a rotating winding drum. A continuous loop is spaced from the winding drum and with the winding drum defines a nip through which the core is inserted and through which the web material is directed. A surface of the continuous loop opposite the winding drum across the nip is configured to move in a direction generally opposite of the winding drum for winding the web material about the core. A rider roll defines a winding space with the winding drum and the continuous loop. The rider roll is movable relative to the continuous loop and the winding drum to allow for an increase in a diameter of the log in the winding space during winding of the web material about the core.

There is provided an image reading device including a power transmission unit that transmits power of a driving source to a transportation roller and a discharging roller, in which the power transmission unit is configured to include a first gear group that constitutes a first power transmission route and a second gear group that constitutes a second power transmission route and that is configured to include a smaller number of gears than the first gear group, the second gear group includes a transportation roller driving gear and is disposed inside a curved inversion route as seen from an axial direction of a rotation shaft, and at least a portion of the transportation roller driving gear is positioned inside a medium transportation region in a width direction of a medium.

A sheet feeding apparatus includes an apparatus body, a feed member feeding a sheet, and a sheet storage member having first and second sheet storage portions. A sheet shifting portion pushes an upstream end of the sheet in the second sheet storage portion in a first direction so as to shift the sheet in the second sheet storage portion to the first sheet storage portion in the first direction. A driving motor generates a driving force moving the sheet shifting portion, and a moving portion moves the sheet shifting portion from a first position to a second position farther from the first sheet storage portion in a state in which the sheet shifting portion does not receive the driving force from the driving motor.

A rewinding machine winds a web material into a log about a core. The web material to be wound is directed about a rotating winding drum. A continuous loop is spaced from the winding drum and with the winding drum defines a nip through which the core is inserted and through which the web material is directed. A surface of the continuous loop opposite the winding drum across the nip is configured to move in a direction generally opposite of the winding drum for winding the web material about the core. A rider roll defines a winding space with the winding drum and the continuous loop. The rider roll is movable relative to the continuous loop and the winding drum to allow for an increase in a diameter of the log in the winding space during winding of the web material about the core.

A sheet conveyance apparatus includes a conveyance member, a drive source, a first member including a first ratchet portion, a second member including a second ratchet portion, and an urging portion. The first ratchet portion has a plurality of first transmission surfaces and a first guide surface. The second ratchet portion has a plurality of second transmission surfaces and a second guide surface. One of the first member and the second member is movable in the axial direction between an engaged position and a separated position. The number of times the holding surface allows the one of the first member and the second member to move from the separated position to the engaged position while the second member rotates once in the rotational direction with respect to the first member is smaller than the number of contact positions included in the plurality of contact positions during the drive transmission period.

Examples disclosed herein relate to a device including a bail arm. In examples, the bail arm to apply force to a receiving surface of an output bin in a first position. In examples, a motor is to move the bail arm from the first position to a second position in which the bail arm does not apply a force to the receiving surface.

A banknote storage unit comprising: a first tape reel banknote storage device; a second tape reel banknote storage device; and a drive transmission means pivotable between engagement with said first tape reel banknote storage device and engagement with said second tape reel banknote storage device.

A sheet conveying device includes a supporting shaft, a rotating unit removable from an installation portion, a movable shaft, and an interlocking device. The rotating unit includes first and second ends, a holding member that holds a rotating body that conveys a sheet. The supporting shaft supports the rotating unit at the first end in an axial direction of the rotating body. The movable shaft is movable in the axial direction and supports the second end. The interlocking device moves the movable shaft per the rotating unit movement. Where the rotating unit is to be moved at a moving amount towards a side in which the rotating unit separates from the supporting shaft as part of removing the rotating unit from the installation portion, the interlocking device moves the movable shaft in the axial direction at a moving amount that is larger than the moving amount the rotating unit.
