To provide an electronic lock device not unlocked only by inserting a key and rotating the key because low safety is improved against a theft or the like occurring by inserting the key into a keyhole and turning the key although a general lock such as a conventional door lock is effective with only that motion.

In the electronic lock device, a tabular piece 5 installed to a connecting rod 3 interlocked with the key is moved left and right by inserting the normal key 6 and rotating the key 6 left and right, and an unlocking signal for an electronic lock 2 is generated by sensors 4a and 4b mounted on both sides of the tabular piece 5. In the electronic lock device, the unlocking signal is transmitted to the electronic lock 2 and the device is formed in a structure in which the electronic lock 2 is unlocked when the signal is taken into a semiconductor integrated circuit A and a signal previously stored in the integrated circuit A coincides with the signal from the sensors 4a and 4b, an arbitrary hole is bored to a pawl 1 for opening and closing a door or the like in a moving core section 7 for the electronic lock 2, and the device is formed in a structure in which the moving core section 7 is inserted into the hole.
