Yet, in above-mentioned formation in the past, as shown in Figure 8, when the adhesive tape 13 on being attached to medium 12 touches thickness and detects bearing 1 a part of, can be because the gap, angle of bearing and detect at thickness on the foreign steamer 1ab of bearing 1 and produce angle θ 1.

Therefore, the total t2 of the thickness t 0 of original medium 12 and the thickness t 1 of adhesive tape 13 should be the displacement of bearing support 4, measure yet the displacement of bearing support 4 but tails off t3 (＜therefore t2), exist under the situations such as the thickness t 1 of adhesive tape is thin, can't detect the problem of adhesive tape.

Summary of the invention

The present invention adopts following formation in order to address the above problem, that is, a kind of paper type determinant device possesses: the reference roller that rotatably is supported; Be fixed in BEARING SHAFT and by can be with this reference roller is mutually opposed at a plurality of bearings of the bracket supports of the direction top offset that leaves this reference roller, gap pumped (conveying) medium between said reference roller and above-mentioned a plurality of bearing, thereby and judge by the displacement that above-mentioned support is measured in the displacement detecting unit whether medium is normal, by between the foreign steamer of above-mentioned a plurality of bearings, pad being set, and the pressure that effect is stipulated between the interior wheel of above-mentioned a plurality of bearings, make above-mentioned a plurality of bearing fixing in above-mentioned BEARING SHAFT.

According to paper type determinant device of the present invention, owing to possessing: the reference roller that rotatably is supported; Be fixed in BEARING SHAFT and by can be with this reference roller is mutually opposed at a plurality of bearings of the bracket supports of the direction top offset that leaves this reference roller, gap pumped (conveying) medium between said reference roller and above-mentioned a plurality of bearing, thereby and judge that by the displacement that above-mentioned support is measured in the displacement detecting unit medium is whether in the normal paper type determinant device, by between the foreign steamer of above-mentioned a plurality of bearings, pad being set, and the pressure that effect is stipulated between the interior wheel of above-mentioned a plurality of bearings, thereby make above-mentioned a plurality of bearing fixing eliminate the gap, angle in above-mentioned BEARING SHAFT, therefore even under the situation of posting adhesive tape on the medium, the also thickness of measuring media and adhesive tape correctly.

The specific embodiment

Below, utilize the example of the embodiment that description of drawings the present invention relates to.For the identical symbol of key element mark common in the accompanying drawing.

(embodiment 1)

(formation)

Except that the formation of the Shaft assembly 14 of the paper type determinant device of embodiment 1, all the other are identical with the formation of the paper type determinant device in the past that utilizes Fig. 4 to Fig. 6 explanation, for simplification identical formation are omitted its detailed description.Below, utilize Fig. 1 and Fig. 2 that the formation of the Shaft assembly of the paper type determinant device of embodiment 1 and the formation of bracket component are described in detail.

As depicted in figs. 1 and 2, the 15th, BEARING SHAFT is to detect the end difference that wheel 1ba joins in the bearing with thickness, in order to prevent that thickness from detecting that bearing 1b comes off and impenetrating thickness detects in each of bearing and takes turns.

The 16th, guarantee the pad in the gap of

bearing

1a and 1b, have pad protuberance 16a, by with chimeric being positioned of internal diameter of detecting bearing foreign steamer 1ab, 1bb.And, when medium 12 detects bearing 1 by thickness, touch medium in order not make pad 16 earlier than detecting bearing, and make the external diameter of the external diameter of pad 16 less than thickness detection bearing.

And BEARING SHAFT 15 is fixed by being close to bearing 1.Carrying out this when being close to, be the direction of hollow arrow A1, A2 to Fig. 1 to bearing in wheel 1aa effect precompressed compression be close to so that gap, the angle θ 1 of aftermentioned Fig. 3 is 0.

As shown in Figure 2, the nut of screwing at the two ends of bearing 15, fixing with dish-shaped bolt from two ends and bearing support 4, thus make detect bearing axially, radially all be positioned.

(action)

More than the paper type determinant device of the embodiment 1 of Gou Chenging moves as follows.Utilize Fig. 3 that this action is described.

At this, same with the Fig. 8 that uses paper type determinant device explanation in the past, adhesive tape 13 is secured at a part of position overlapped that detects bearing 1a with thickness on medium 12, describes as an example with the situation that this medium 12 is passed through between reference roller 2 and thickness detection bearing 1.

When medium 12 passes through between reference roller 2 and thickness detection bearing 1, same with Fig. 8 of in the past paper type determinant device, detect the power of bearing foreign steamer 1ab effect tilt angle theta 1, detect the interior wheel of bearing 1aa, 1ba and always fix the position with directive effect precompressed compression near each other, therefore detect bearing foreign steamer 1ab and 1bb always across pad 16 and always eliminate the gap, angle, detect bearing foreign steamer 1ab and do not tilt and become θ 1=0 thereby make to directive effect power near each other.

Therefore, the displacement t4 of bearing support 4 equates that with the total t2 of the thickness t 1 of the thickness t 0 of medium 12 and adhesive tape 13 promptly therefore t4=t2 can correctly measure adhesive tape thickness t 1.

(effect of embodiment 1)

As implied above, according to the paper type determinant device of embodiment 1, owing to possessing: the reference roller that rotatably is supported; Be fixed in BEARING SHAFT and can be detected bearings with this reference roller is mutually opposed at a plurality of thickness of the bracket supports of the direction top offset that leaves this reference roller, to the gap pumped (conveying) medium between said reference roller and above-mentioned a plurality of bearing, and judge by the displacement that above-mentioned bearing support is measured in the displacement detecting unit whether medium is normal, by between the foreign steamer that detects bearing at above-mentioned a plurality of thickness pad being set, and act on the pressure of stipulating between interior wheel to above-mentioned a plurality of thickness detection bearings, make above-mentioned a plurality of thickness detect bearing fixing in above-mentioned BEARING SHAFT, thereby eliminate the gap, angle, therefore even under the situation of posting adhesive tape on the medium, the also thickness of measuring media and adhesive tape correctly.

As mentioned above, the present invention can be widely used in the employed automatic trading apparatus of bank and other financial mechanism etc., and the displacement of the thickness by detecting medium comes the media processing apparatus of treatment media.
