A staple removing device includes an aligning part with which a fold of a booklet stitched by a staple having a crown portion and leg portions and folded along an extension direction of the crown portion is brought into contact, a guide part that guides the fold of the booklet to the aligning part; and a removing part having an operating part that moves in a direction intersecting with the fold of the booklet, to engage with the crown portion of the staple that stitches the booklet.

A label dispenser coupled to product-transporting carts at retail facilities includes a label roll support arm supporting multiple label rolls thereon, a label guide arm including openings that permit a leading portion of the backing substrate of a label roll to pass therethrough, and a side wall interconnecting the label roll support arm and the label guide arm. The label guide arm also includes an upper portion located above the openings and configured to support the backing substrates of the label rolls thereon. The label guide arm further includes an edge configured to facilitate separation of a leading peelable label from the backing substrate in response to a force applied by the user when pulling the leading portion of the backing substrate of the label roll through the opening of the label guide arm.

A printer capable of separating a print medium from a mount and ejecting the print medium includes: a platen roller configured to feed, along a feeding path, a mount to which a print medium temporarily adheres; a print head configured to print on the print medium, the print head being opposed to the platen roller; a driven roller that is movable between a first position and a second position different from the first position; a separation member configured to separate a feeding path of the mount and a feeding path of the print medium; and a looseness prevention mechanism configured to prevent the mount from being loose while the driven roller moves from the second feed position to the first feed position. The first position is a position where the driven roller is opposed to the platen roller. The driven roller is configured to be driven by the platen roller while coming in contact with the mount.

A label printer includes a print head, a transporting roller, a peeling roller, and a control unit, wherein the control unit controls a current value to be supplied to a peeling motor configured to rotate the peeling roller such that a transport force of the peeling roller for transporting the backing sheet is equal to or greater than a minimum force required for peeling the label and is greater than a maximum friction force between the peeling roller and the backing sheet, and the maximum friction force and a maximum friction force between the transporting roller and the label sheet are set such that the maximum friction force between the peeling roller and the backing sheet is equal to or smaller than a transport force of the peeling roller that sets a transport error of the label sheet by the transporting roller to be within an acceptable value.

A method of removing backing film from a sheet element is provided. The sheet element has a preimpregnated layer, and sheets of backing film are adhered to the top and bottom of the preimpregnated layer. The backing film has a different coefficient of thermal expansion than the preimpregnated layer, and a plane of the sheet element is defined by the peripheral edge. A shear strain is created between the backing films and the preimpregnated layer by cooling the sheet element. A fluid stream is directed at a portion of the peripheral edge, the fluid stream being directed in the plane of the sheet element. The fluid stream causes the backing films to separate from the top and bottom of the preimpregnated layer. A differential pressure is simultaneously applied to the backing films relative to the fluid stream to cause the backing films to be removed from the preimpregnated layer.
