PURPOSE:To make the movement of backet and adjusting plate holder timingly, by providing the guide onto the side plate of the device main body, restricting the guide pins of backet and adjusting plate holder by the movable part to move along the guide. CONSTITUTION:When an oscillating gear 72 moves anti-clockwise around a shaft 74, a guide pin 54 of backet 26 moves along a horizontal groove 68A with being restricted by the radius direction groove 76A of the oscillating gear 72, and the backet 26 moves towards the horizontal direction. After this, when the guide pin 54 moves being mated with vertical groove 68B of side panel 66, the backet moved downward towards the device main body 24 fixing the center core 14 of magnetic sheet pack onto the drive shaft 32. On the other hand, a guide pin 56 of adjusting plate holder moves along the circumference groove 78A of the oscillating gear 72 when the guide pin 54 is moving, therefore the position of adjusting plate holder does not change. |
