摘要：
A method for locking a housing door of a VCR, or the like. The housing door is locked in response to a locking signal supplied to a servo portion by a controller if no key is operated for a predetermined period of time regardless of the VCR power-on or off state, the existence of a tape within the deck, and the operation status of the VCR. If a key is input while the housing door is locked, the count parameter is reset to 0, and then, the counting is resumed. Thus, the housing door is unlocked only when necessary, so that the intrusion of foreign materials into the deck can be prevented.
