1. A signal output apparatus comprising:
- an impact application unit configured to generate and apply an impact to a sheet material;
an impact reception unit configured to receive the applied impact;
a signal output unit configured to output a signal in response to the impact received by the impact reception unit from the impact application unit, the signal output unit being disposed on at least one of the impact application unit side and the impact reception unit side; and
a calibration unit configured to calibrate at least one of the impact applied by the impact application unit and the signal output from the signal output unit.

12. A method for identifying a sheet material comprising the steps of:
-
obtaining a first output signal by applying a first impact by an impact application unit to an impact reception unit without a sheet material;
adjusting the first impact so that the value of a first output signal corresponding to the first impact is within a predetermined range;
applying a predetermined second impact by the impact application unit to the impact reception unit with a sheet material being provided;
outputting the second impact applied to the sheet material as a second output signal from the impact reception unit; and
identifying the sheet material on the basis of the second output signal and information provided in advance for identifying the sheet material.

13. A method for identifying a sheet material comprising the steps of:
-
obtaining a first output signal from a signal output unit by applying a first impact by an impact application unit to an impact reception unit without a sheet material;
changing the signal output unit so that the value of the first output signal will be included within a predetermined range;
applying a predetermined second impact by the impact application unit to the impact reception unit with a sheet material being provided;
outputting the second impact applied to the sheet material as a second output signal from the impact reception unit; and
identifying the sheet material on the basis of the second output signal and information provided in advance for identifying the sheet material.

15. A method for identifying a sheet material comprising the steps of:
-
obtaining a first output signal by applying a first impact by an impact application unit to an impact reception unit to a reference sheet material;
adjusting the first impact so that the value of a first output signal corresponding to the first impact is within a predetermined range;
applying a predetermined second impact by the impact application unit to the impact reception unit with a sheet material being provided;
outputting the second impact applied to the sheet material as a second output signal from the impact reception unit; and
identifying the sheet material on the basis of the second output signal and information provided in advance for identifying the sheet material.
