It is further explained that the number status of the count display area 423 will not be increased as follows: A, B, and C:

A. When the test object 6 contains the metal substance, the central control unit 5 will not control the activation of the label unit 3, therefore, the central control unit 5 will not receive the classification signal S3 of the label unit 3. Therefore, the conditions are not met (1) The central control unit 5 receives the needle detection signal S1 and the classification signal S3, and the number displayed in the count display area 423 will not increase.

B. When the test object 6 does not contain metal substances, but the label 62 is damaged, even if the central control unit 5 controls the activation of the label unit 3 because it determines that the test object 6 does not contain metal substances, it still does not meet the conditions (2) The central control unit 5 determines that the test object 6 does not contain metal substances and the label 62 is not damaged. Therefore, the number displayed in the count display area 423 will not increase.

C. During the process of strengthening the detection action as in paragraph [0050], because the test object 6 contains the metal substance, it does not meet the condition (2) the central control unit 5 judges that the test object 6 does not contain metal substance And the label 62 is not damaged. That is, even if the counting module 22 detects the corresponding component, it will not increase the number displayed in the counting display area 423.

D. When the operator accidentally places an item or hand close to the counting module 22, because the condition (1) the central control unit 5 receives the needle detection signal S1 and the classification signal S3, it will not increase The count shows the number in the area 423.
