Measuring device, sheet-shaped material transporting device, image formation device and measuring method

1. A measuring device, wherein a feed-out member feeds out an uppermost one of a plurality of sheet-shaped materials stacked on a base by rotating in contact with the uppermost sheet-shaped material, comprising:

a detector that detects a force in the feed-out direction of the sheet-shaped materials imparted to the base and the sheet-shaped materials not in contact with the feed-out member, the force being generated by feeding-out the uppermost sheet-shaped material.

2. A sheet-shaped material transporting device comprising:

a base capable of bearing a plurality of sheet-shaped materials;

a feed-out member that feeds out an uppermost one of the sheet-shaped materials on the base by rotating in contact therewith; and

a detector that detects a force in the feed-out direction of the sheet-shaped materials imparted to the base and the sheet-shaped materials not in contact with the feed-out member, the force being generated by feeding-out the uppermost sheet-shaped material.

3. The sheet-shaped material transporting device according to claim 2 , wherein the detector detects any compressive force or tensile force from the base and the sheet-shaped materials not in contact with the feed-out member or information based on any displacement of the base.

4. The sheet-shaped material transporting device according to claim 2 , further comprising:

a moving speed information detector that detects information on a moving speed of sheet-shaped materials fed out by the feed-out member; and

a feed-out force controller that controls the force with which the feed-out member feeds out the sheet-shaped materials on the basis of the information detected by the moving speed information detector and the information detected by the detector.

5. The sheet-shaped material transporting device according to claim 4 , further comprising:

a contact state adjuster that adjusts the state of contact between sheet-shaped materials stacked on the base on the basis of the information detected by the moving speed information detector and the information detected by the detector.

6. The sheet-shaped material transporting device according to claim 5 , wherein the contact state adjuster adjusts the state of contact between sheet-shaped materials by blowing air toward the sheet-shaped materials stacked on the base.

7. The sheet-shaped material transporting device according to claim 4 , further comprising:

a cleaner that cleans the feed-out member.

8. The sheet-shaped material transporting device according to claim 4 , wherein the feed-out force controller controls the force with which the feed-out member feeds out the sheet-shaped materials by controlling the load that the feed-out member imposes on the sheet-shaped materials.

9. An image formation device comprising:

an image formation part that forms an image on a sheet-shaped material; and

a sheet-shaped material transporting device that transports a plurality of sheet-shaped materials to the image formation part, the sheet-shaped material transporting device comprising a base capable of bearing the plurality of sheet-shaped materials, a feed-out member that feeds out an uppermost one of the sheet-shaped materials on the base by rotating in contact therewith, and a detector that detects a force in the feed-out direction of the sheet-shaped materials imparted to the base and the sheet-shaped materials not in contact with the feed-out member, the force being generated by feeding-out the uppermost sheet-shaped material.

10. The image formation device according to claim 9 , further comprising a display that performs prescribed displaying according to information detected by the detector.

11. The image formation device according to claim 9 , wherein the detector detects any compressive force or tensile force from the base and the sheet-shaped materials not in contact with the feed-out member or information based on any displacement of the base.

12. The image formation device according to claim 9 , further comprising a moving speed information detector that detects information on a moving speed of sheet-shaped materials fed out by the feed-out member and a feed-out force controller that controls the force with which the feed-out member feeds out the sheet-shaped materials on the basis of the information detected by the moving speed information detector and the information detected by the detector.

13. The image formation device according to claim 12 , further comprising a contact state adjuster that adjusts the state of contact between the sheet-shaped materials stacked on the base on the basis of the information detected by the moving speed information detector and the information detected by the detector.

14. The image formation device according to claim 13 , wherein the contact state adjuster adjusts the state of contact between the sheet-shaped materials by blowing air toward the sheet-shaped materials stacked on the base.

15. The image formation device according to claim 12 , further comprising a cleaner that cleans the feed-out member.

16. The image formation device according to claim 12 , wherein the feed-out force controller controls the force with which the feed-out member feeds out the sheet-shaped materials by controlling the load that the feed-out member imposes on the sheet-shaped materials.

17. A measuring method for a measuring device wherein a feed-out member feeds out an uppermost one of a plurality of sheet-shaped materials stacked on a base by rotating in contact with the uppermost sheet-shaped material, the method comprising:

detecting a force in the feed-out direction of the sheet-shaped materials imparted to the sheet-shaped materials not in contact with the feed-out member, the force being generated by feeding-out the uppermost sheet-shaped material.
