Claims

[Claims for Utility Model Registration] A first gear rotatably provided with respect to the mounting board and having wings that engage with the reel hub; A second gear is provided between the first gear and the second gear, and the second gear is rotatable relative to the first gear. A reel having a slip member which slips upon receiving a rotational force of a predetermined magnitude or more and transmits rotational force between a first gear and a second gear. A shaft; A second gear of the reel shaft is supplied with rotational force through a rotational force transmission means that does not transmit rotational force of a predetermined magnitude or more from a rotational force supply means that supplies two rotational speeds; a drive gear which transmits the rotational force from the rotational force supply means to the second gear of the reel shaft; and an idler gear rotatably provided to simultaneously transmit the idler gear to the first and second gears of the reel shaft; The second gear is transmitted from the gearing and rotational force supply means through the drive gear.
By supplying the rotational force supplied to the first gear to the first gear without passing through the slip member, the rotational force is increased to a predetermined magnitude or more without causing slip from the second gear to the first gear. and a second position where the idler gear is spaced apart from the first and second gears of the reel shaft. an idler gear moving lever which is flexible and has the rotation center of the reel shaft, the rotation center of the idler gear, and its own rotation center aligned in a straight line; an idler gear correspondingly disposing the idler gear moving lever in a first position and correspondingly disposing the idler gear moving lever in a second position supplying rotation at the lower of the two speeds of the rotational force supply means; A reel shaft power transmission mechanism for a magnetic recording tape traveling device, comprising: a moving lever driving means; and;
