Claims

[Scope of utility model registration request]

In a mechanism for regulating the position of an idler that swings along the circumferential surface of a drive rotary body to drive a supply reel disk or a take-up reel disk, the idler is spaced apart from the circumferential surface of the drive rotary body. A member for storing and holding a pressing member that locks the idler and presses it against the drive rotating body so as to swing the idler, a part of which receives the idler itself that is separate from the drive rotating body. An idler position regulating mechanism for driving a reel, comprising an idler position regulating section that regulates the position of the idler, and the position of the idler is regulated by the idler position regulating section.
