Insertion confirmation circuit which is the starting point of the connection loop composed of
Is a monitor circuit that detects whether the input voltage is at a high level or a low level, 9 is a pull-up resistor that sets the input of the monitor circuit 8 to a high level when the connection loop is open,
Reference numeral 10 denotes a ground for setting the input of the monitor circuit 8 to a low level when the connection loop is short-circuited.

The operation of the antenna device configured as described above will be described. The insertion confirmation line 6 from the monitor circuit 8 of the insertion confirmation circuit 7 to the transmission / reception module 2 and the insertion confirmation line 6 between the transmission / reception module 2 and the control signal module 3 are short lines 5 of the transmission / reception module 2.
Connected by The insertion confirmation line 6 between the transmission / reception module 2 and the control signal module 3 and the insertion confirmation line 6 between the control signal module 3 and the power supply module 4 are connected by the short line 5 of the control signal module 3.

On the other hand, if there is any one of the modules 2, 3 and 4 for which insertion has been forgotten, for example, if the control signal module 3 is forgotten to be inserted, an insertion between the transmission / reception module 2 and the control signal module 3 will be performed. Since the confirmation line 6 and the insertion confirmation line 6 between the control signal module 3 and the power supply module 4 are open, the monitor circuit 8 of the insertion confirmation circuit 7 detects a high level by the pull-up resistor 9. I do.

In other words, when the modules 2, 3, and 4 are forgotten to be inserted, the monitor circuit 8 detects a high level. Since the circuit 8 detects the low level, it can be electrically confirmed whether or not each module 2, 3, 4 has been forgotten to be inserted.

Even if the user forgets to insert it or if there is another erroneous insertion, the monitor circuit 8 detects the low level, so that it is no longer possible to confirm that the user has forgotten or erroneously inserted. However, when the short-open control circuit 11 is opened, the monitor circuit 8 of the normal connection loop detects a high level,
