PURPOSE:To improve the handling efficiency and to reduce the space of the title device by combining a means, which opens and closes a side plate with a hinge provided in the upper edge of the side plate as a fulcrum, and a hinge structure having two turning fulcrums and a turning stop spring to constitute a device. CONSTITUTION:A hinge 100 consists of a fixed plate 16, an intermediate plate 20, an inverting plate 18, two shafts 21 and 22, and a stop spring 25, and the fixed plate 16 is fixed to the frame side, and the inverting plate 18 is fixed to the side of a side plate 14, and the fixed plate 16 and the inverting plate 18 are connected through the intermediate plate 20 by two shafts 21 and 22, and the stop spring 25 is fixed to the intermediate plate 20 to damp turning of the fixed plate 16 and the intermediate plate 20. Consequently, the side plate 14 is smoothly opened and closed with the upper edge as the fulcrum of turning and is stopped in the intermediate open state or the maximum open state. Thus, the space is reduced and the handling efficiency is improved. |
