Abstract

A check chip of the present invention employed at a usage of a sensor measuring device is provided with a structural characterizing portion of a convex shape, concave shape or a penetration hole at a location, by which a user is considered to pick up, and the state of the structural characterizing portion is made to be different from that of a structural characterizing portion provided on a correction chip which is similar to the check chip, in a size, the number of the structural characterizing portions, or placement location.

According to the check chip constructed as above, the difference from the correction chip can be easily identified even by a visually handicapped person or a weak-sighted person, according to the difference in the structural characterizing portion, from the touch, thereby preventing the person from using the check chip and the correction chip with confused.

Claims

1. A check chip which is mounted on a measuring device employing an exclusively used sensor, and checks operations of the measuring device itself, wherein

the check chip is provided thereon with at least one structural characterizing portion which makes a user of the measuring device recognize differences from a correction chip for correcting errors that occur with lot changes in the exclusively used sensor.

2. The check chip of claim 1, wherein

the structural characterizing portion has a shape, such as a convex shape, which can be recognized by the user from the touch, and is provided in a location by which the user is considered to pick up the check chip.

3. The check chip of claim 1 or claim 2, wherein a difference between the check chip and the correction chip resides in the size of the structural characterizing portion, when the correction chip has the structural characterizing portion.

4. The check chip of claim 3, wherein

the size of the structural characterizing portion provided on the check chip is larger than that of the structural characterizing portion provided on the correction chip.

5. The check chip of claim 3, wherein

the size of the structural characterizing portion provided on the check chip is smaller than that of the structural characterizing portion provided on the correction chip.

6. The check chip of any of claims 1 to 5, wherein

the check chip is provided with the structural characterizing portion on the both sides of the check chip.

7. The check chip of any of claims 1 to 6, wherein a difference between the check chip and the correction chip resides in the number of the structural characterizing portions.

8. The check chip of claim 7, wherein

the number of the structural characterizing portions provided on the check chip is larger than that of the structural characterizing portions provided on the correction chip.

9. The check chip of claim 7, wherein

the number of the structural characterizing portions provided on the check chip is smaller than that of the structural characterizing portions provided on the correction chip.

10. The check chip of claim 8, wherein

structural characterizing portion on an attention attracting character printed on an upside of the check chip, among plural structural characterizing portions provided on the check chip, has optical penetrability.

11. The check chip of any of claims 1 to 10, wherein a difference between the check chip and the correction chip reside in the shape of the structural characterizing portion.
