This is applied to a data receiving device that includes a power supply circuit that supplies power to the receiving circuit and the transmitting circuit, and especially when the receiving circuit is not receiving a signal, the power supply circuit supplies power to the transmitting circuit. The device is characterized by having means for controlling the power supply so as to stop the signal and supply power to the transmitting circuit when a signal is received. [Operation] According to the present invention, power supply to the transmitting circuit is stopped when no signal is being received. When a signal is received, it becomes possible to supply power to the transmitting circuit. Therefore, power consumption in the transmitting circuit can be saved. [Examples] The present invention will be explained in more detail below with reference to examples shown in the attached drawings. FIG. 1 is a block diagram showing an embodiment of a data receiving device according to the present invention. In FIG. 1, 1 is a receiving circuit, 2
is a transmitting circuit that transmits data to a data terminal, 3 is a power supply circuit, 4 is a signal detection circuit, 5 is a power supply control circuit, 6 is received data from another device, 7 is received data after passing through the receiving circuit 1, 8 is the data sent to the data terminal. 9 is a power control signal obtained by recognizing the presence or absence of a received signal in the signal detection circuit 4;
10. 11 indicates the power supply path. Data 6 sent from another device is input to the receiving circuit l,
The data is taken into the data receiving device. Data 7 obtained through the receiving circuit 1 is input to the transmitting circuit 2 and the signal detecting circuit 4. The signal detection circuit 4 detects whether or not data having a specific data pattern ENP has been received, based on a communication protocol agreed upon in advance with other devices. When the specific data pattern ENP is not detected in the signal detection circuit 4, a power control signal 9 that turns off the power supply to the transmitting circuit 2 is sent to the power supply control circuit 5, and the signal detection circuit 4 detects the specific data pattern ENP. When the data pattern ENP is detected, a power control signal 9 that turns on power supply to the transmitting circuit 2 is sent to the power control circuit 5. The receiving circuit 1 and the signal detecting circuit 4 are constantly supplied with power from the power supply circuit 3 to operate the respective circuits, making it possible to detect the specific pattern ENP. FIG. 2 is a diagram showing an example of the power supply control circuit 5. In FIG. 2, 12 is a switch for connecting or disconnecting the power supply path 10 and the power supply path l1. switch l
2 connects or disconnects the power supply path 10 and the power supply path 1l in accordance with the power control signal 9 sent from the signal detection circuit 4 described above. In such a structure,
When the power supply control circuit 5 is not receiving a signal containing the specific data pattern ENP, the power supply control circuit 5 stops supplying power to the transmitting circuit 2 using the power supply control signal 9, and when receiving a signal containing the specific data pattern ENP, Power is supplied to the transmitting circuit 2 using a power supply control signal 9.
