FIG. 1 is a diagram showing a connection of a control circuit device according to an embodiment of the present invention. In the control circuit device of this embodiment, a power supply voltage is supplied from the motherboard 1 to the control circuit 2, and thereafter, the signal line of the motherboard 1 is connected to the control circuit 2. In a normal logic IC or the like, since a normal operation is not guaranteed if a voltage higher than the power supply voltage is input, the power supply voltage is supplied first.

めの入力端子４と出力端子５を設けている。However, it is still insufficient to connect the power supply voltage line first, and the number of control circuits is large, and when the number of connectors between the motherboard and the control circuit increases,
When the connector is inserted obliquely, power is supplied to the circuit side, but there may be a disadvantage that the operation of the control circuit is started in a state where the connection between the motherboard and the control circuit is insufficient. In order to prevent this inconvenience, in the control circuit device of this embodiment, an input terminal 4 and an output terminal 5 for confirming connection are provided at both ends of the connector 3.

１に接続された後となるように構成している。The connection confirmation output terminal 5 indicates that the power supply voltage is supplied from the motherboard 1, and outputs a connection confirmation output signal to the motherboard 1 again. This connection confirmation output signal is sent to the connection confirmation input terminal 4 on the motherboard 1 side.
The connection confirmation input signal from the connection confirmation input terminal 4 is taken into the control circuit 2 again. As shown in FIG. 2, the connector 3 of the control circuit device of this embodiment has a connection confirmation input terminal 4 and a connection confirmation output terminal 5 at both ends.
And a power supply terminal 6 and a signal terminal 7 for data transfer. The dimensions of the connector conductor are set short so that the connection confirmation input terminal 4 and the connection confirmation output terminal 5 are connected after the power supply voltage or the signal line from the other motherboard 1. The signal terminal 7 is set shorter than the power terminal 6. Therefore, at the time of insertion, the power supply terminal 6 → the signal terminal 7 → the connection confirmation terminals 4 and 5 are connected in this order. As described above, the connection confirmation input terminal 4 and the connection confirmation output terminal 5 are arranged at both ends.
One of the input / output confirmation signals is not obtained, and finally both the connection confirmation input terminal 4 and the connection confirmation output signal 5 of the control circuit 2 are connected because the other signal terminal is securely connected to the motherboard 1. It is configured to be after connection.

ーダンス状態にする。A power reset circuit 8 is provided in the control circuit 2, and a connection confirmation input terminal 4 is connected to an input of the power reset circuit 8. The power reset circuit 8 resets the operation until the connection confirmation input signal is applied,
Before the connection confirmation signal is given, the operation of the control circuit 2 is prevented from starting. Further, even if connected to the motherboard 1 before the operation starts, all the signal lines are set to a high impedance state before the signal starts so as not to affect other control circuits.
