1. A sheet counting apparatus for counting the number of sheets, comprising:
- a plurality of thickness detection units, which are separately disposed length-wise on a transport passage of the sheets, for detecting thicknesses of the sheet passing length-wise through the transport passage; and
a control unit for determining the number of sheets passing through the transport passage on the basis of the detection outputs from said thickness detection units;
wherein said thickness detection unit detects the thickness of the sheet as voltage value, and said control unit determines the number of sheets m on the basis of the following equation;
where, Vm;
the voltage value of the thickness detection unit, Vo;
the voltage value at the 0-sheet level, L;
the length of the sheet in the short length direction, and t0-t1;
the passing time of the sheet.

Abstract
The bill counter has thickness detection units 31, 32, and 33 for detecting the thickness of a bill passing through a transport passage. The thickness detection units 31, 32, and 33 are separately placed on the transport passage. Waveform outputs from the thickness detection units 31, 32, and 33, provided by detecting the thicknesses of predetermined parts of bill passing through the transport passage are compared with waveform data previously stored in a storage unit and the number of bills passing through the transport passage is determined.

-
a plurality of thickness detection units, which are separately disposed length-wise on a transport passage of the sheets, for detecting thicknesses of the sheet passing length-wise through the transport passage;
a control unit for determining the number of sheets passing through the transport passage on the basis of the detection outputs from said thickness detection units;
an output unit for outputting information that the number of sheets is undefined, when the number of passage sheets cannot be determined; and
wherein said output unit outputs information that the number of sheets is undefined, when said control unit determined that the sheet is skew and an angle of skew of the sheet is larger than a predetermined value on the basis of the detection outputs.
