A feed-out device for extracting the leading end of a strip wound on a cassetted reel has a stripper hinged to the forward end of a support, which is inserted into the cassette during feed-out. The support is provided with a bearing surface which engages the strip roll periphery, and the stripper is biased resiliently to engage the roll periphery -- thus irrespective of the size of the roll, the thrust of the stripper against its surface and its angle of attack remain substantially constant.
An apparatus for stripping the leader from a roll of film. A stripper arm is pivotally supported at one end and biased toward the film. The free end of the arm carries a pivotally supported crescent shaped stripper tip defining a leading edge, a trailing edge and a stripping surface. As a result of the shape of the tip, both the leading and trailing edges rest upon the outer surface of the coiled film assuring a constant angle between the stripping surface and the film regardless of the shape of the outer film convolution.
A drive-out assembly to thread a film wound on a reel or in a coil 2 includes an arm 7 to swing into the cartridge and engage the film with a drive-out roller 8 which drives the film in an unwinding direction to drive the free end over a stripper member 10 urged against the film. The drive for the drive-out roller 8 includes a first drive gear 20 which rotates a driven gear 23 through an intermediate gear 21 to drive a shaft 19 having a drive gear 23 to drive the drive-out roller 8 through other intermediate gears 24, 8'.
For lifting and grasping a starting portion of a film located in a coil, the method includes driving a coil by a friction wheel abutting against an outer surface of the coil with an end edge of a starting portion of the coil located arbitrarily on the outer surface, placing a separating wedge under a prestress on the outer surface of the coil and lifting the starting portion of the film from the coil by an edge of the separating wedge, and first turning the coil against a latter uncoiling direction, and after a recognition of a position of the end edge of the starting portion of the film turning the coil in the uncoiling direction.
A magazine body constituting a paper magazine is provided with a paper mouth through which a recording paper is advanced. Behind the paper mouth, a separating plate having a thin thickness and formed from plastic is disposed. The separating plate contacts a periphery of a recording paper roll contained in the paper magazine. The recording paper roll is rotated in a paper advancing direction by a drive roller. Upon rotation of the recording paper roll, the separating plate contacting the periphery of the recording paper roll separates a top of the recording paper from the recording paper roll. After that, the separating plate leads the top of the recording paper to the paper mouth. The recording paper is advanced to the outside of the paper magazine through the paper mouth.
A paper sheet storage and payout device, which, by winding and unwinding tape between a first take-up drum on which the tape is wound from one end, and a second take-up drum on which the tape is wound from the other end, with paper sheets placed thereupon, stores and pays out paper sheets. A separation mechanism is provided on the payout side of the tape from the second take-up drum, and during payout separates the paper sheets from the wrapping peripheral region of the tape wrapped around the second take-up drum. This separation mechanism is provided with a separation member which separates paper sheets from the wrapping peripheral region, and a sliding portion which holds the separation member, and which slides so as to track the amount of tape wrapped around the second take-up drum by bring into contact with the wrapping peripheral region a guide roller.
