PURPOSE:To make possible an internal frame having the dial plates of the various styles of type to be changed automatically and rapidly, by a rotation of a plurality of arms mounted to a rotating body suitably and by a displacement of a hook for hanging the internal frame provided thereon in the vertical and horizontal directions. CONSTITUTION:A hanging hook 22 is lowered and an inside frame 19 is fitted to a dial outside frame 2 of a dial by an operation of a cam 30 for a vertical movement with a cam shaft 20 is rotated in the first time, when an arm 14 providing a prescribed dial inside frame 19 is carried to a changing position for the dial outside frame 1, then, the inside frame 19 is charged into the dial outside frame 2 with the hook 22 is disengaged from a latch 26 by an operation of a cam 31 for the horizontal motion. In the case of the inside frame 19 being exchanged with another necessary inside frame 19, the hook 22 is also engaged to the latch 26 of the inside frame 19 charged in the dial outside frame 2, thereafter, the inside frame 19 is drawn out from the outside frame 2 and being suspended by the arm 14, the this inside frame 19 is charged into the outside frame 2 correctry with the lowering and horizontal motions of the hook are carried out when the to be exchanged arm 14 of the inside frame 19 is achieved to the exchange position with the arm 14 is rotated.
