Claims

[Scope of utility model registration request]

A bearing that rotatably holds the spare roll at its shaft end is fixed to the frame of the rotating device, and a ratchet mechanism is attached to the shaft end of the spare roll, and the intermittent rotating plate of the ratchet mechanism is connected to the spare roll. A swinging lever that is fixed to the shaft of the roll and rotates the intermittent rotating plate extends toward the frame, and the frame has a sliding member capable of reciprocating sliding movement, on which the tip of the swinging lever is pivotally supported. A rotating device for a spare roll, characterized in that a moving rod is installed, and the sliding rod is connected to a drive section installed on the frame.
