And, if use addition from the displacement detecting signal 31 of adjacent displacement detecting sensor 9a shown in Figure 3 and 9b gained and 32 adhesive tape thickness sum signal 30, then the detection signal of adhesive tape portion increases, be partial to side ground simultaneously on detection roller 5a and the 5b and under even have, also can detect the effect of adhesive tape by the situation that detects the roller inclination at the both ends of adhesive tape 4.
In addition, if use addition from the displacement detecting signal 40 of adjacent displacement detecting sensor 9a shown in Figure 4 and 9b gained and 41 adhesive tape thickness sum signal 42, then the detection signal of adhesive tape portion increases, be partial to side ground simultaneously on detection roller 5a and the 5b and under even have, also can detect the effect of adhesive tape by the situation that detects the roller inclination at the both ends of adhesive tape 4.
Fig. 5 represents to judge other embodiment of the method for Continuous pressing device for stereo-pattern on the judgement bank note in judgment processing portion 11.
In Fig. 5, the signal of differential is carried out the adhesive tape thickness sum signal 42 of Fig. 4 in 43 expressions of adhesive tape thickness differential signal.Mark 44,45 expressions are used for the threshold value of judgment processing.So, if the absolute value of adhesive tape thickness differential signal 43 be threshold value 44 (absolute value of threshold value 44=threshold value 55) or more than, then be judged as adhesive tape, if less than threshold value, then be judged as no adhesive tape.
And, even displacement sum signal 23 differential of adjacent the displacement detecting signal of addition Fig. 2 also can be obtained effect same.
According to the present invention, if use the adhesive tape thickness differential signal 43 that addition is carried out differential from the adhesive tape thickness sum signal 42 of the displacement detecting signal 40 of displacement detecting sensor 9a and 9b gained and 41, then the detection signal of adhesive tape portion increases, be partial to side ground simultaneously on detection roller 5a and the 5b and under even have, also can detect the effect of adhesive tape by the situation that detects the roller inclination at the both ends of adhesive tape 4.
