FIG. 1 is a block diagram showing a cloth amount discriminating apparatus in an embodiment of the present invention. In the figure, 1 is an analog value generating means for selecting a correction value, 2 is an analog value input section, 3 is an A / D converter for converting an analog value into a digital signal, 4 is a storage section, and 5 is a cloth amount determination in the storage section. Numerical value group 6 is a numerical value group for correcting the amount of cloth discrimination, which correlates with the digital numerical value input by the AD converter 3. Numeral 7 is a detection means for cloth amount discrimination, and a numerical value corresponding to the cloth amount is inputted to the comparison calculation processing part 8. Then, in the normal cloth amount determination, it is compared with a predetermined cloth amount determination numerical value group 5 to determine which of a plurality of levels the cloth amount is. However, in the case of only one model, there is no problem, but due to differences in models, differences in motor torque, etc., it becomes necessary to correct the discriminant value numerical value group for discrimination by the similar comparison calculation. Here, in the present invention, a standard value is set in the comparison calculation for selecting only the correction value corresponding to the analog input value, and the correction value selected as the standard value is compared with the cloth amount generation input value to perform the correction. A 4-bit A / D converter can obtain 16 kinds of correction values with only one input terminal. With 8 bits, 256 correction values can be obtained, but this is the first to be done by having an AD converter.

There is a group of correction value numerical values 6 up to ΔD N, and the value V XN and the standard determination value D given from the cloth amount determination detection means 7 in the case of the standard
Judgment is made by calculating and comparing XN and the correction value ΔD N.
The analog value is V A1- V AN as V A as shown in Fig. 2.
It can be created by a combination of the fixed resistor 12R1 and the fixed resistor 13R2 in consideration of the precision according to the resolution of the -D converter 3, but the relationship of the numerical values in particular when R1> R2 is fixed resistor 12,
