Abstract: A detection unit for detecting a data row of a press position and a load at the press position; an input/storage unit for inputting and storing a value serving as a reference for determining a bend point in a relation between the press position and the load at the press position; a data-row calculation unit for calculating a data row of a press position and a load at a constant distance interval based on the data row of the press position and the load detected; a slope calculation unit for calculating a slope of the load based on the press position and the load at the press position detected; and a bend-point determination unit for determining a point, at which the calculated slope of the load exceeds the value serving as the reference for determining the bend point, as the bend point are provided.

Abstract translation: 检测单元，用于检测按压位置的数据行和按压位置处的负载; 输入/存储单元，用于输入和存储用作确定按压位置与按压位置处的负载之间的关系中的弯曲点的基准的值; 数据行计算单元，用于基于所述按压位置的数据行和检测到的负载来计算按压位置的数据行和恒定间隔的负载; 坡度计算单元，用于基于所述按压位置和所检测到的所述按压位置处的载荷来计算所述负载的斜率; 以及弯折点确定单元，用于确定所计算的负载的斜率超过用作确定弯曲点的基准的值作为弯曲点的点。
