。[Claims for Utility Model Registration] (1) In a processing device that has a plurality of connection means and processes signals from external means detachably connected to these connection means, one of the plurality of connection means comprising a selector signal generating means for applying a selector signal to the connecting means except for one of the connecting means, and connected means of the external means connected to these connecting means are configured to drop the selector signal to ground when connected; An automatic switching device for electrical equipment, further comprising selector means for controlling so that only the external signal from the connecting means, in which the selector signal falls to the ground, is sent to the processing means. (2) In paragraph 1 of the claims for utility model registration,
An automatic switching device for electrical equipment, characterized in that the selector means includes means for electrically fixing the connection when detecting that the selector means has fallen to the ground. (3) In paragraph 1 of the claims for utility model registration,
An automatic switching device for electrical equipment, wherein the selector signal generating means generates a code signal for identifying each of the connecting means, and the selector means detects which code signal falls to ground. (4) In paragraph 1 of the claims for utility model registration,
An automatic switching device for electrical equipment, wherein the selector signal is applied from the selector means. (5) In paragraph 1 of the claims for utility model registration,
An automatic switching device for electrical equipment, characterized in that the selector signal is applied from the processing means.
