    • A conventional induction heating cooker which operates two inverters at the same time, with only one input current detecting circuit provided, cannot measure each of input currents to each of the plurality of inverters, and cannot control input powers by feedback control on input currents. In the induction heating cooker which has a plurality of inverters, when the input power varies to the inverter which has less input power supplied, the variation hardly influences the cooking. The induction heating cooker according to the present invention fixes the operating frequency for the inverter which has less input power supplied and performs the feedback control of the input current for the inverter which has bigger input power supplied.
    • 同时只有一个输入电流检测电路同时操作两个反相器的常规感应加热烹调器不能测量到多个逆变器中的每一个的每个输入电流,并且不能通过对输入电流的反馈控制来控制输入功率。 在具有多个逆变器的感应加热烹调器中,当输入功率变化到输入功率较小的逆变器时,变化几乎不影响烹调。 根据本发明的感应加热烹调器固定了输入功率较小的逆变器的工作频率,并对输入功率较大的逆变器进行输入电流的反馈控制。

    • A conveying distance control device includes a conveying roller; a first detecting unit detecting rotational positions of the conveying roller; a line sensor sequentially detecting marks arranged on a test chart; a calculation unit, and a control unit. The calculation unit calculates a skew angle between a line passing through positions of a first mark and a second mark and a conveying direction of the conveying roller. The control unit obtains conveying distance errors indicating differences between corrected conveying distances not including errors caused by the skew angle and theoretical conveying distance of the marks in association with the rotational positions of the conveying roller, calculates a correction value for correcting a conveying distance of the conveying roller based on relationships between the conveying distance errors and the rotational positions of the conveying roller, and controls the conveying distance of the conveying roller based on the correction value.
    • 输送距离控制装置包括输送辊; 第一检测单元,检测输送辊的旋转位置; 线传感器,其顺序地检测布置在测试图上的标记; 计算单元和控制单元。 计算单元计算通过第一标记的位置的线与第二标记之间的偏斜角和输送辊的输送方向。 所述控制单元获得指示与所述输送辊的旋转位置相关联的不包括由所述歪斜角度引起的误差和所述标记的理论输送距离的校正传送距离之间的差异的传送距离误差,计算校正所述传送距离的校正值 输送辊基于传送距离误差与输送辊的旋转位置之间的关系,并且基于校正值来控制输送辊的输送距离。
