US 5,499,115 A · Television receiving apparatus having a video tape recorder unit therein with a function for preventing an electric shock

Abstract

A television receiving apparatus having a video tape recorder unit therein with a function for preventing an electric shock, for preventing a user from inserting his fingers into a cabinet when the video tape recorder unit is removed from the cabinet for repair or the like, includes a locking mechanism for locking a controller door panel at a position where it is closed. The controller door panel is used for operating the video tape recorder unit contained in the apparatus. In order to surely obtain security of the user even when the locking operation is forgotten, the apparatus further includes a mechanism for interrupting supply of electric power to a television receiver when the absence of the video tape recorder unit in the cabinet is detected and when the controller door panel is detected to be opened at and more than a predetermined angle. A possibility that the user will receive an electric shock can thus be eliminated.
