A print medium feeding device removes a second sheet from a print medium that is in a state in which a first sheet, the second sheet, a the third sheet are superposed, superposes the first sheet and the third sheet, and feeds the first sheet and the third sheet to a printing device. The print medium feeding device includes: a first roller configured to come into contact with the third sheet and to be driven to rotate by movement of the third sheet; a second roller configured to come into contact with the first sheet and to be driven to rotate by movement of the first sheet; a roll-up member disposed upstream of the first roller and configured to roll up the second sheet; and a transmission mechanism configured to transmit a rotational force of the first roller to the roll-up member.

There is provided a component supply device for supplying a component to a component mounter, including: a transporter that transports a carrier tape in which the component is stored and of which an upper surface is sealed with a cover tape, along a transport path; a peeler that peels off the cover tape from the carrier tape via an opening portion disposed above the transport path; and a cover that makes an open state of the opening portion variable. The cover sets the open state of the opening portion to be any of a first open state allowing the peeler to capture the cover tape and a second open state where an opening size of the opening portion is smaller than that of the first open state and passage of the cover tape peeled off from the carrier tape is not impeded.

A stripping device for stripping sheet-shaped objects from a roller includes at least one stripper. The stripper is mounted rotatably about a bearing and includes stripping portion configured to be tapering to a point and a support portion which is different from the stripping portion. The stripping portion and the support portion are arranged relative to each other and the stripper is mounted such that, when the stripper is pressed against the roller with prestressing during operation, the stripper has two mutually spaced apart contact points with the roller, which contact points are defined by the stripping portion and the support portion of the stripper.

Proposed is an apparatus for removing release paper, the apparatus including a removal part that grips and removing release paper attached to a surface of a battery cell and is provided with a gripping detection sensor, a recovery part that collects the release paper removed from the surface of the battery cell and is provided with an input detection sensor, and a detection part that detects the release paper remaining not removed by performing vision measurement on the surface of the battery cell. In addition, proposed is a method of removing release paper from a battery cell using the above-described apparatus, while determining a removal state of the release paper.
