2. Description of the Related Art In recent years, there has been a shortage of places, facilities, etc. for treating waste materials, which have become serious. Along with this, there is an increasing demand for reuse of parts that have been treated as waste materials. Under such circumstances, there is a demand for reusing the CRT even in a device using the CRT.

Among the methods for reusing a CRT, there is a method for reusing the glass portion of the CRT. In this case, it is necessary to remove the mounting frame wound around the outer periphery of the glass part from the CRT.

[0004]

However, in the prior art, in the CRT equipment, since there are various types of CRTs depending on the model, it is difficult to automatically separate and disassemble the mounting frame from the CRT. That is, conventionally, when performing the disassembling and disassembling, the types were visually observed, and the disassembling and disassembling were performed manually one by one. For this reason, it takes a lot of time for the separation and dismantling work, and it is difficult to realize the labor cost and other costs. In addition, dust or noise generated during disassembly may adversely affect the human body of the worker, so that a dust protector or the like must be used, which is a problem of poor efficiency.
