Abstract: A scanning apparatus utilizing gravity acceleration for scanning is provided. The scanning apparatus comprises a U-shaped housing, a shaft bearing, a housing and a scanning head. The shaft bearing passes through the housing with two ends thereof respectively and rotationally fastened on two sidewalls of the U-shaped housing, thereby the housing is vertically and rotationally fastened in the U-shaped housing. The scanning head is disposed in the housing with an engageable piece engaged with a hook-type element of the housing so as to fasten the scanning head at a predetermined position close to the top end of the housing. When the scanning head is going to scan, the engagement between the engageable piece and the hook-type element is released and a starting power is applied to the scanning head by gravity acceleration. Thereby the scanning head is guided to move downward to scan via cooperation between a guiding piece and a guiding rail. The scanning speed of the scanning head is determined by the starting power controlled by a predetermined angle contained between the housing and the U-shaped housing.

Abstract translation: 提供利用重力加速扫描的扫描装置。 扫描装置包括U形壳体，轴承座，壳体和扫描头。 轴轴承分别穿过壳体的两端，并旋转地固定在U形壳体的两个侧壁上，从而将壳体垂直并旋转地固定在U形壳体中。 扫描头设置在壳体中，具有与壳体的钩型元件接合的可接合件，以便将扫描头紧固在靠近壳体顶端的预定位置处。 当扫描头要扫描时，可接合件和钩型元件之间的接合被释放，并且通过重力加速将起动力施加到扫描头。 从而扫描头被引导向下移动以通过引导件和导轨之间的协作进行扫描。 扫描头的扫描速度由容纳在壳体和U形壳体之间的预定角度控制的起动功率决定。
