PROBLEM TO BE SOLVED: To make it possible to automatically supply power to an external apparatus when output signals are received and to stop the supply of power to the external apparatus when no output signals are received by transmitting the output signals received from a signal generator and detecting whether a signal inputting section receives the output signals or not. SOLUTION: When output signals are generated by a signal generator 1, the output signals are received by a signal inputting section 3 of an automatic power supply and then the received output signals are transmitted to an external apparatus 2. When the output signals are received by the signal inputting section 3, a signal detecting section 4 detects the output signals and sends the power input into a switching section 5 to the external apparatus 2 through a plug socket 6. On the other hand, when the output signals are not received by the signal inputting section 3, it is recognized by the signal detecting section 4 that no output signals are detected and then the supply of power to the external apparatus 2 is stopped by the switching section 5. Therefore, turning-on/off of a power switch of the external apparatus 2 requires no man power and thereby labor and time can be saved. |
