<p>PURPOSE:To stably keep the support state of a cassette holder with reference to a chassis by a method wherein detachment-preventing walls situated in positions faced with support walls so as to sandwich pieces to be supported as viewed from a direction perpendicular to shafts of support pins are formed collectively with support members. CONSTITUTION:Circular and comparatively small support holes 16a, 16a are formed in rear ends at lower end parts of pieces 16, 16 to be supported of a cassette holder 6. For support members 8, 8', the following are integratedly formed of a metal: fixation parts 34, 34 which are nearly rectangular as viewed from the upper part and which are flat-boardlike; nearly rectangular walls 35, 35 which are erected from positions deformed to rear end sides of nearly intermediate parts in the right and left direction on the surface of the fixation parts 34, 34 and whose thickness direction is extended to the right and left direction; wall parts 36, 36 which are erected from front end edges on the surface of the fixation parts 34, 34 and which are faced to the front and rear direction; and cylindrical support pins 37, 37 which are faced toward the outside of the support walls 35, 35 and which protrude from side faces. The wall parts 36, 36 are composed of stopper walls 36a, 36a and detachment-preventing walls 36a, 36b.</p> |
