There is following problems in the device that patent documentation 1 is put down in writing: passed through under the situation between reference roller and the measuring roll in the paper class; Because the elastomeric element by softness between the outer ring of measuring roll and the turning axle constitutes, so because the frictional resistance of measuring roll and paper class can cause measuring roll to tilt or crawl in the carrying direction.There is such problem thus: owing to the distance between measuring roll and the displacement detecting sensor changes, so can't detect the thickness of paper class and adhesive tape etc. exactly.

In addition, the device that patent documentation 2 is put down in writing is, the pushing roller utilization deadweight of pushing measuring roll or pushing force and suppress the vibration of measuring roll on above-below direction.And about having passed through under the situation between reference roller and the measuring roll in the paper class, measuring roll is in carrying direction such problem that tilts or crawl, and both hypothesis is not open yet.Therefore, about preventing in tilt this point or this point that prevents to crawl is not considered of carrying direction.In addition, do not consider on the turning axle direction, to arrange a plurality of measuring rolls.

Summary of the invention

The objective of the invention is to address the above problem, provide a kind of prevent measuring roll carrying on the direction inclination and crawl and can detect the thickness detector for paper sheet of the thickness of paper class and adhesive tape etc. exactly.

In order to address the above problem, for example adopt following structure.

The application comprises a plurality of means that address the above problem, and as an one of which example, in first structure, is characterised in that: be provided with the anti-roller that crawls that contacts with the outer ring of said a plurality of measuring rolls and rotate.Thus, have the prevention measuring roll and carrying inclination on the direction and the effect of crawling.In addition, the effect of beating that has the measuring roll in the time of to suppress to sandwich the paper class between reference roller and the measuring roll through measuring roll and the anti-frictional resistance that crawls between the roller.The said anti-roller that crawls for example be configured in the roughly the same height of the rotation center of said a plurality of measuring rolls on, perhaps be configured in a plurality of displacement detecting sensor sides top of the displacement that detects each measuring roll.The preferred said anti-roller that crawls for example is the structure with rigidity higher than said a plurality of measuring rolls.

In addition; In second structure; The roller portion of convex is set with constant interval on the said anti-roller that crawls, the roller portion of said convex is inserted in the gap between the said adjacent measuring roll, while the contacts side surfaces of outer ring of side and said measuring roll of the roller portion of said convex is rotated.Thus, have the prevention measuring roll and carrying inclination on the direction and the effect of crawling.In addition, the effect of beating that has the measuring roll when suppressing to sandwich the paper class between reference roller and the measuring roll through measuring roll and the anti-frictional resistance that crawls between the roller.

In the 3rd structure, dispose the said anti-roller that crawls in both sides across the outer ring of said measuring roll.Because the anti-roller that crawls contacts at two places with the outer ring of measuring roll, stop measuring roll carrying inclination on the direction and the effect of crawling so improved.In addition, improved the effect of beating of the measuring roll when suppressing to sandwich the paper class between reference roller and the measuring roll through measuring roll and the anti-resistance that crawls between the roller.

In addition, in the 4th structure, the rotational speed of the periphery of the said anti-roller that crawls is different with the rotational speed of the periphery of said measuring roll.Thus, improved the cleaning effect that the paper scrap that will be attached on the measuring roll etc. is peeled off.

Below utilize description of drawings embodiment.

Embodiment 1

Utilize Fig. 1, Fig. 2, Fig. 3, Fig. 4 that one embodiment of thickness detector for paper sheet of the present invention is described.Fig. 1 is the roughly integrally-built general view that thickness detector for paper sheet is shown.Fig. 2 illustrates the structure of observed Fig. 1 from the top.Fig. 3 illustrates the structure of observed Fig. 1 from the side.Fig. 4 is illustrated in the structure under the situation that does not have the anti-roller 5 that crawls in the structure of Fig. 1.

Thickness detector for paper sheet 1 shown in Figure 1 constitutes and comprises: roller 2, and through rotary drive mechanism (not shown), revolving force is passed to the gear 29 of Fig. 2, thereby is located at

reference roller

11,12,13 rotations on the turning axle 10; Roller 3, the

measuring roll

6,7,8 that is located on the turning axle 14 is urged on

reference roller

11,12,13 and driven rotation; The anti-roller 5 that crawls, the roller 27 that is located on the turning axle 26 is contacted with or is urged on measuring

roll

6,7,8 and driven rotation;

Displacement detecting sensors

18,19,20,21,22,23 such as vortex flow displacement transducer detect the action of the

measuring roll

6,7,8 that moves to the top according to the thickness of paper class 4.

In addition, as shown in Figure 2, displacement detecting sensor is provided with 2 to 1 measuring roll, and general arrangement is at both ends.For example, to a measuring roll 6, dispose 2

displacement detecting sensors

18,19 at both ends roughly.In addition, the turning

axle

10,14,26 of roller 2, roller 3, the anti-roller 5 that crawls has been applied in precompressed through bearing 28 with the mode that does not move in the axial direction and has been installed on the housing 25.In addition,

displacement detecting sensor

18,19,20,21,22,23 is located on the circuit substrate (not shown), and circuit substrate is installed on the housing 25.In addition, the pushing force between reference roller and the measuring roll is set according to the turning axle 10 and the axle base of turning axle 14.Likewise, measuring roll and anti-pushing force of crawling between the roller are set according to the turning axle 14 and the axle base of turning axle 26.In addition, thus the anti-roller 5 of crawling also can apply pushing force to measuring roll through pushing turning axles 26 such as springs.

In addition, as shown in Figure 3, the anti-roller 5 that crawls is configured to, and on rotation center through measuring roll 6 and the line parallel with the carrying direction of paper class 4 30, contacts with outer ring 16.In addition, the roller 27 for the anti-roller 5 that crawls can use metallic roll, rubber rollers etc.

In said measuring

roll

6,7,8, between outer ring 16 that the cylinder-like part by metal etc. constitutes and turning axle 14, be filled with the elastomeric element 15 of the softness of rubber etc.In addition, as shown in Figure 2, said elastomeric element 15 also can be in the outer ring 16 two end portions be slit into

elastomeric element

15a, 15b and be provided with.In addition, said elastomeric element 15 can be bonding or non-bonding with outer ring 16.Thus, if at

reference roller

11,12,13 and measuring

roll

6,7, sandwich paper class 4 between 8,15 quantitative change shapes of elastomeric element then with the thickness of paper class, thus move to the top outer ring 16.This amount of movement is detected by

displacement detecting sensor

18,19,20,21,22,23 and the corresponding detection signal of thickness of output and paper class.

As stated, said measuring

roll

6,7,8 is because the distortion that causes through elasticity detects the thickness of paper class, so there is the problem of crawling easily, therefore, preventing to crawl through the roller 5 of preventing crawling helps the raising of paper class thickness accuracy of detection.The anti-roller 5 that crawls adopts the rigidity structure higher than said measuring

roll

6,7,8 on the whole.For example, preferably turning axle and outer ring are integrally formed structure etc. through metal or synthetic resin.

In addition, can also anti-roller 5 rotations of crawling be driven through other drive units.Again in addition, the rotational speed of the periphery through making the anti-roller 5 that crawls is different with the rotational speed of the periphery of measuring

roll

6,7,8, can improve the cleaning effect, that is: will peel off attached to the foreign matters such as paper scrap on the

measuring roll

6,7,8.

If in the cash automatic processing device, use the thickness detector for paper sheet of present embodiment, then said detection signal is fed to the determination process section (not shown) of cash automatic processing device.The postural cue of determination process section crooked (inclination on the carrying direction) during through measuring roll, displacement (position on the turning axle direction) according to detection signal and bank note judge that bank note is overlapping more than two overlapping carrying or post the adulterium certificate of adhesive tape etc., and export this decision signal.In addition, postural cue is used for that detection signal is modified to bank note does not have crooked state and is used to obtain the position of bank note through measuring roll.

In addition, in above-mentioned explanation, three groups of reference roller and measuring roll are illustrated, still, in order can the whole face of paper class to be detected, reference roller disposes a plurality of on the direction vertical with the carrying direction of paper class with measuring roll.

In addition, in Fig. 4, show the structure of the situation that in the structure of Fig. 1, does not have the anti-roller 5 that crawls as comparative example.As shown in Figure 4, when paper class 4 is passed through between reference roller 12 and measuring roll 7, exist because the problem that the frictional resistance between paper class 4 and the measuring roll 7 causes measuring roll 7 to tilt or crawl in the carrying direction.Like this, measuring roll tilt or the situation of crawling under because measuring roll 7 changes with displacement detecting sensor 20, the distance between 21, so existence can't detect the problem of the thickness of paper class exactly.

Therefore, in the present embodiment, be contacted with or press against on the measuring roll, can stop the inclination of measuring roll or crawl through the roller 27 that makes the anti-roller 5 that crawls.Thus, the effect that can detect the thickness of paper class is exactly arranged.The effect of beating of the measuring roll in the time of in addition, can suppressing to sandwich the paper class between reference roller and the measuring roll through the frictional resistance between the roller 27 of measuring roll and the anti-roller 5 that crawls in addition.In addition, if in the roller 27 of the anti-roller 5 that crawls, use rubber rollers, then owing to the frictional resistance with measuring roll increases, so can obtain bigger inhibition effect.
