Abstract

A biological information measurement device of the present invention includes: measurement unit (7) connected to sensor mounting unit (4); control unit (8) connected to measurement unit (7); power source switch (14) interposed between control unit (8) and power source (13); and power source switch drive circuit (11) connected to sensor mounting unit (4). One-shot pulse circuit (12) is interposed between sensor mounting unit (4) and power source switch drive circuit (11), and power source switch drive circuit (11), which is driven by an output of one-shot pulse circuit (12), opens and closes power source switch (14).

Claims

1. A biological information measurement device comprising:

a body case having a sensor mounting unit;

a measurement unit connected to the sensor mounting unit;

a control unit connected to the measurement unit;

a power source supplying power to the control unit;

a power source switch interposed between the control unit and the power source; and

a power source switch drive circuit connected to the sensor mounting unit,

wherein a one-shot pulse circuit is interposed between the sensor mounting unit and the power source switch drive circuit, and

wherein the power source switch drive circuit, which is driven by an output of the one-shot pulse circuit, opens and closes the power source switch.

2. The biological information measurement device according to claim 1, wherein the power source switch drive circuit drives the power source switch to connect the control unit and the power source when a sensor is mounted into the sensor mounting unit.

3. The biological information measurement device according to claim 1, wherein the control unit is provided with a power source enabling unit connected to the power source switch drive circuit.

4. The biological information measurement device according to claim 3, wherein the power source switch drive circuit includes an OR circuit.

5. The biological information measurement device according to claim 1, wherein the one-shot pulse circuit includes:

a one pulse timer circuit connected to the sensor mounting unit and an inverter connected to the one pulse timer circuit.
