摘要： PURPOSE:To accurately discriminate type of material and mass, etc., by initially setting a bridge circuit including at least one sensor coil to an unbalanced state in advance, and setting the circuit so that it is significantly changed in response to the variation of such as type of material to be detected. CONSTITUTION:For example, when a balancing ratio is set to 5.5, an unbalanced voltage of a bridge circuit 1 with a sensor coil 1 apparoached with a material to be tested such as iron, i.e., an output voltage of an operational amplifier 3 is as shown in the table. Thus, when an output is -0.75V through the adjustment of a lower limit value setting resistor R4, if the 1st operational amplifier 3 produces an output, silver coil, aluminum, brass and copper out of the materials to be tested can be discriminated from iron. If the operational amplifier 13 generates an output only when the output voltage of the operational amplifier 3A is

摘要： PURPOSE:To prevent occurrence of a counting error even when the thickness of each commodity is different by permitting a pair of detectors to count piled up commodities in parallel, comparing counted results of both detectors and outputting the counted results only when they are equal. CONSTITUTION:The piled up commodities whose number is measured are placed on a base stand, and a supporting rail is placed approximately in parallel with the stand so as to hold the commodities placed on the stand. A pair of detectors 1 and 1A are movably installed along the supporting rail. A counter 4 counts outputs arising when the detectors 1 and 1A move from one end to the other onn the supporting rail, and a comparator 4 compares the counted value of the counter when the detectors 1 and 1A reach the other end. As a result, responding the occurrence of a coincidence signal, a comulative counter 12 cumulates either one of the counted values, and obtains the counted value of the piled up commodities.
