Magazine for containing strip of recording medium

Claim 1

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.
