Abstract

A hardness tester includes: a tester main body, an inputter receiving an operation input from a user, a controller controlling an entirety of the hardness tester including the inputter, and a display which displays a predetermined image by being controlled by the controller. The controller includes a measurement procedure suggester and a suggestion switcher. The measurement procedure suggester suggests a procedure for measuring an indentation dimension value to the user. When receiving an operation input for proceeding to a subsequent procedure via the inputter, the suggestion switcher switches suggestions from the measurement procedure suggester and suggests the subsequent procedure to the user.

Claims

1. A hardness tester for testing a hardness of a work piece by forming an indentation by pressing an indenter against a surface of the work piece, and by measuring an indentation dimension value, comprising:

an inputter configured to receive an operation input from a user; and

a controller configured to control an entirety of the hardness tester including the inputter, the controller comprising;

a measurement procedure suggester configured to suggest to the user a procedure for measuring the indentation dimension value; and

a suggestion switcher configured to switch, when receiving an operation input for proceeding to a subsequent procedure via the inputter, suggestions from the measurement procedure suggester to suggest to the user the subsequent procedure.

2. The hardness tester according to claim 1, further comprising:

a display on which a predetermined image is displayed by being controlled by the controller;

wherein, the measurement procedure suggester is further configured to suggest to the user the procedure for measuring the indentation dimension value, by displaying on the display a plurality of icons which are images of each procedure for measuring the indentation dimension value; and

the suggestion switcher is further configured to cause an icon showing a subsequent procedure to be highlighted among a plurality of icons while not highlighting an icon showing a current procedure, and is further configured to switch suggestions from the measurement procedure suggester so as to suggest to the user the subsequent procedure.

3. The hardness tester according to claim 2, wherein when forming an indentation by pressing an indenter against a surface of a work piece, the suggestion switcher causes an icon showing a first procedure to be highlighted while not highlighting the icons showing other procedures, and further initializes suggestions from the measurement procedure suggester.

4. The hardness tester according to claim 2, wherein when receiving an operation input for returning to a previous procedure via the inputter, the suggestion switcher switches suggestions from the measurement procedure suggester to suggest to the user the previous procedure.

5. The hardness tester according to claim 3, wherein when receiving an operation input for returning to a previous procedure via the inputter, the suggestion switcher switches suggestions from the measurement procedure suggester to suggest to the user the previous procedure.

6. The hardness tester according to claim 1, wherein the suggestion switcher is configured to receive an input of the indentation dimension value as the operation input for proceeding to a subsequent procedure.

7. The hardness tester according to claim 2, wherein the suggestion switcher is configured to receive an input of the indentation dimension value as the operation input for proceeding to a subsequent procedure.

8. The hardness tester according to claim 3, wherein the suggestion switcher is configured to receive an input of the indentation dimension value as the operation input for proceeding to a subsequent procedure.

9. The hardness tester according to claim 4, wherein the suggestion switcher is configured to receive an input of the indentation dimension value as the operation input for proceeding to a subsequent procedure.

10. The hardness tester according to claim 5, wherein the suggestion switcher is configured to receive an input of the indentation dimension value as the operation input for proceeding to a subsequent procedure.

11. The hardness tester according to claim 6, wherein when receiving the operation input for returning to a previous procedure via the inputter, the suggestion switcher deletes the indentation dimension value entered when the current procedure is processed.

12. The hardness tester according to claim 7, wherein when receiving the operation input for returning to a previous procedure via the inputter, the suggestion switcher deletes the indentation dimension value entered when the current procedure is processed.

13. The hardness tester according to claim 8, wherein when receiving the operation input for returning to a previous procedure via the inputter, the suggestion switcher deletes the indentation dimension value entered when the current procedure is processed.

14. The hardness tester according to claim 9, wherein when receiving the operation input for returning to a previous procedure via the inputter, the suggestion switcher deletes the indentation dimension value entered when the current procedure is processed.

15. The hardness tester according to claim 10, wherein when receiving the operation input for returning to a previous procedure via the inputter, the suggestion switcher deletes the indentation dimension value entered when the current procedure is processed.
