Abstract
Abstract A magazine includes a case for accommodating a strip of recording medium as wound around a tubular core, a support shaft provided in the case and supporting the inner periphery of the core for rendering the medium rotatable, and reverse rotation preventing members permitting forward rotation of the core when the recording medium is paid off from the case and preventing the core from rotating in a winding direction opposite to the forward rotation. Even when the recording medium is subjected at its leading end to an external pushing-in force or tends to be rotated by shaking or vibration during handling, the reverse rotation preventing members restrain the medium from rotating in the opposite direction to prevent the leading end from slipping into the case.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
213 words
A magazine containing a strip of recording medium as wound around a tubular core, said magazine comprising: a case for accommodating the recording medium therein; a support shaft fixedly provided in the case and supporting the inner periphery of the tubular core for rendering the recording medium rotatable, said case having an opening portion defined therein for placing the interior of the case in communication with the outside and through which the recording medium is paid off from the case; and reverse rotation preventing means associated with said support shaft for permitting rotation of the tubular core in a forward direction when the recording medium is paid off through the opening portion and for preventing the tubular core from rotating in a winding direction that is opposite to the forward direction, said reverse rotation preventing means including at least one projecting member which is in frictional contact with the inner periphery of the tubular core for providing resistance at the inner periphery of the core that inhibits the rotation of the tubular core in the winding direction, each said projecting member projecting from the outer periphery of the support shaft in a direction extending substantially tangential to the outer periphery of the support shaft and toward the inner periphery of the tubular core.
Claim 2
Dependent Claim
213 words
A magazine containing a strip of recording medium as wound around a tubular core, said magazine comprising: a case for accommodating the recording medium therein; a support shaft fixedly provided in the case and supporting the inner periphery of the tubular core for rendering the recording medium rotatable, said case having an opening portion defined therein for placing the interior of the case in communication with the outside and through which the recording medium is paid off from the case; and reverse rotation preventing means associated with said support shaft for permitting rotation of the tubular core in a forward direction when the recording medium is paid off through the opening portion and for preventing the tubular core from rotating in a winding direction that is opposite to the forward direction, said reverse rotation preventing means including at least one projecting member which is in frictional contact with the inner periphery of the tubular core for providing resistance at the inner periphery of the core that inhibits the rotation of the tubular core in the winding direction, each said projecting member projecting from the outer periphery of the support shaft in a direction extending substantially tangential to the outer periphery of the support shaft and toward the inner periphery of the tubular core.
Claim 3
Dependent Claim
32 words
A magazine as defined in claim 1, wherein said reverse rotation prevention means includes a plate extending through the support shaft diametrically thereof, and each said projecting member extends from said plate.
Claim 4
Dependent Claim
25 words
A magazine as defined in claim 1, wherein the support shaft comprises synthetic resin, and each said projecting member is integral with the support shaft.
Claim 5
Dependent Claim
49 words
A magazine as defined in claim 1, wherein the case has a lower closure and an upper closure overlapping the lower closure, the opening portion defined therebetween, and the lap of the lower and the upper closures having at least one aperture extending therein for receiving a dispenser roller.
Claim 6
Dependent Claim
30 words
A magazine as defined in claim 4, wherein the recording medium in the case has a leading end positioned at the outer end of the opening portion of the case.
Claim 7
Dependent Claim
31 words
A magazine as defined in claim 5, and further comprising a transparent member forming an outer end portion of the upper closure and defining the outer edge of each said aperture.
Claim 8
Dependent Claim
14 words
A magazine as defined in claim 1, wherein each said projecting member is saw-shaped.
