信機器の他に家電機器などにも広く用いられている。2. Description of the Related Art Recent communication devices such as cordless phones and answering machines use a commercial power supply. Most of these communication devices use a power adapter because they have a smaller power supply capacity than large communication devices.
The power adapter converts direct current (for example, 5 V, 12 V, etc.) requiring commercial power (100 V AC), and is widely used in home appliances in addition to communication devices.

容量・コネクタ形式が異なっている。[0003] In recent maintenance forms of communication equipment, there are many cases where a customer brings a failed communication equipment directly to a business office in charge of repairing a failure. At this time, if the communication device and the power adapter are brought in at the same time, the details of the failure can be confirmed on the spot, but in many cases, the failure cannot be carried and the power adapter is required. Power adapters differ in voltage, current capacity, and connector type depending on the model.

However, since there are many models, it is difficult to prepare all power adapters, which is not economically preferable. Therefore, the failure content is checked after the power adapter is prepared, and the customer failure report content may not be sufficiently understood.
