ELECTRONIC ALARM LOCK DEVICE FOR AUTOMOBILE

PURPOSE:To certainly prevent the theft for a car by executing the alarm operation in correspondence with the alarm signals outputted from a breakage detecting means including an electric conductor which is attached onto a window glass and detects the breakage of the window glass, door opening detecting means, error signal alarm means, etc. CONSTITUTION:An electric conductive body 1 which is fragile is attached at the position where the view field is not shielded on a window glass of a car, and a breakage detecting means 3 into which the output signal is input is installed onto an alarm lock device body 2. In the alarm lock device 2, a door opening detecting means 4 which receives the output signal of a door switch and generates an alarm signal only the time when a door is opened is installed. Further, a secret language recognizing means 8 which collates the cryptograph code input from a releasing key means with the set cryptograph code and outputs a release signal in the case when the both codes accord, and an error signal observing means 9 which counts the output of discordance in the above- described collation and outputs an alarm signal in the case when a certain numeric value is reached are installed. Alarms are generated in correspondence with the outputs of the means 3, 4, and 9.
