    • A lens attaching/detaching device includes a lever holding plate that has an elastic piece which presses a lock releasing lever in a direction away from a locking mechanism and holds the lock releasing lever while the lock releasing lever is guided by a lower case. The lock releasing lever includes a first sliding part and a second sliding part which are guided by the lower case. The first sliding part and the second sliding part are arranged at different positions in a Z direction and an X direction orthogonal to a Y direction. An operation part is disposed at the same position as that of the first sliding part in the Z direction. An actuation part is disposed at the same position as that of the second sliding part in the Z direction. The lower case includes a first guiding part which guides the first sliding part and the second guiding part which guides the second sliding part.
    • 镜头安装/拆卸装置包括杆保持板,其具有弹性件,该弹性件在远离锁定机构的方向上按压锁定释放杆并且在锁定释放杆由下壳体引导的同时保持锁定释放杆。 锁定释放杆包括由下壳体引导的第一滑动部件和第二滑动部件。 第一滑动部和第二滑动部配置在与Y方向正交的Z方向和X方向的不同位置。 操作部在与第一滑动部的Z方向相同的位置配置。 致动部分设置在与Z方向上的第二滑动部分相同的位置上。 下壳体包括引导第一滑动部的第一引导部和引导第二滑动部的第二引导部。

    • An electronic device is provided which is capable of reducing variations in the brightness of lights emitted from the light emitting parts. The electronic device has: a housing; a plurality of light sources provided within the housing, each light source emitting light along a light axis, the light axes of the light sources being directed in the same direction; and plurality of light guide plates provided within the housing, the light guide plates guiding the lights emitted from the light sources, respectively. Each light guide plate has a light incident plane on which the light emitted from the light source is incident and a light emitting part that is exposed at an outer surface of the housing. One of the light guide plates has a light incident plane angle that is different from the light incident plane angle of another light guide plate so that light axes of the lights that are guided within the light guide plates pass through the light emitting parts, wherein the light incident plane angle is an acute angle that is formed between the normal line of the light incident plane and the light axis of the light that is incident on the light incident plane.
    • 提供了能够减少从发光部发出的光的亮度变化的电子装置。 电子设备具有:一个壳体; 设置在所述壳体内的多个光源,每个光源沿着光轴发射光,所述光源的光轴以相同的方向被引导; 以及设置在所述壳体内的多个导光板,所述导光板分别引导从所述光源发出的光。 每个导光板具有从光源发射的光入射的光入射平面和暴露在壳体的外表面的发光部。 导光板之一具有与另一导光板的光入射面角度不同的光入射面角度,使得在导光板内被引导的光的光轴穿过发光部分,其中, 光入射面角度是形成在光入射面的法线与入射到光入射面的光的光轴之间的锐角。
