    • A door opening/closing mechanism fitted on a door that closes and opens an opening formed in the body of an apparatus by being brought into and out of contact with the rim of the opening has cam mechanisms that permit the door to engage with and disengage from the body at either of the right and left sides of the door. The cam mechanisms can be brought into a first lock position in which they lie symmetrically at both sides of the door and into a second lock position in which they lie symmetrically at both sides of the door, and each have a hinge pin that serves as a rotation axis in the second lock position and a groove cam that engages with the hinge pin in such a way as to be movable relative to the hinge pin. The groove cam has a slide portion on which a part of the innermost portion of the hinge pin slides when the cam mechanism is moved from the first lock position to the second lock position and of which the length in the direction of the width of the door is greater than the maximum permissible variation in the outermost distance (L) between the two groove cams formed at both sides of the door. When the door is closed, the cam mechanisms at both sides are kept in the first lock position and, when the door is opened at one side, the door slides and thereby causes the cam mechanism at the other side to be brought into the second lock position so as to be rotatably locked in the second lock position.
    • 安装在门上的门打开/关闭机构,其通过与开口的边缘接触而闭合并打开形成在设备的主体中的开口,具有允许门接合和脱离 身体在门的右侧和左侧。 凸轮机构可以进入第一锁定位置,其中它们对称地位于门的两侧并进入第二锁定位置,在该第二锁定位置中,它们对称地位于门的两侧,并且每个都具有用作 在第二锁定位置的旋转轴线和与铰链销啮合的凹槽凸轮,以便相对于铰链销可移动。 槽凸轮具有滑动部分,当凸轮机构从第一锁定位置移动到第二锁定位置时,铰链销的最内部分的一部分滑动到该滑动部分,并且其中门的宽度方向上的长度 大于形成在门的两侧的两个凹槽凸轮之间的最外侧距离(L)的最大允许变化。 当门关闭时,两侧的凸轮机构保持在第一锁定位置,并且当门在一侧打开时,门滑动,从而使另一侧的凸轮机构进入第二锁定 位置以可旋转地锁定在第二锁定位置。
