Abstract

A load detecting device includes a plurality of load sensors which are disposed in a matrix shape and correcting means for setting at least one of the plural load sensors as a standard load sensor and for correcting level of output values of each load sensors to level of output value of the standard load sensor on the basis of the output values of each load sensors.

Claims

1. A load detecting device comprising:

a plurality of load sensors which are disposed in a matrix shape and

correcting means for setting at least one of the plural load sensors as a standard load sensor and for correcting level of output values of each load sensors to level of output value of the standard load sensor on the basis of the output values of each load sensors.

2. A load detecting device according to claim 1, wherein the load sensors are formed by printing and the standard load sensor is disposed at approximately central portion of the matrix shape.

3. A load detecting device comprising:

a plurality of load sensors which are disposed in a matrix shape and in which the load sensors in a standard line are set and

correcting means for correcting level of output values of each load sensors to level of output value of the load sensors in the standard line on the basis of the output values of each load sensors.

4. A load detecting device according to claim 3, wherein the load sensors are formed by printing in a row direction of the matrix and the standard line is a line which is disposed at approximately central portion of the matrix shape.
