In production and use, the cabinet of the chassis generally achieves the protection effect, but its emphasis is different, so its appearance and application are different, but no matter what difference, the cabinet will achieve the following functions in general.

首先，要达到的一个效果就是提供空间给电源、主板等着这些重要但又比较零散易受影响并且易于出现故障的部件。

First, one effect to achieve is to provide space for power supply, motherboard and other important but relatively scattered and vulnerable parts prone to failure.

其次，由于其内部部件容易受环境的影响，所以自动售货机还要起到保护的作用，如防压、防尘、防冲击同时还有防电磁干扰和辐射的功能。

Secondly, because the internal parts of the vending machine are easily affected by the environment, the vending machine also plays a protective role, such as pressure prevention, dust prevention, impact protection, and also the functions of electromagnetic interference and radiation protection.

然后，自动售货机还供给了许多便于运用的面板开关指示灯等，让操作者更方便地操作微机或调查微机的运转状况。

Then, the vending machine also provides many easy to use panel switch indicator lights, so that the operator can operate the computer more conveniently or investigate the operation of the microcomputer.
