The leading end 4b of the ever 4 changes the light blocking quantity of the photocoupler of a displacement sensor 7. When the paper sheet P having a length (l) reaches the place separated by the length (l) in front of the rollers 2, 5, the rollers 2, 5 are started and the detection roller 5 moves up and down according to the eccentricity of the roller 2 and a thickness signal when there is no paper sheet P is outputted. A reference value (So) is set from the max. and min. values at that time. Next, when the paper sheet P is held between the rollers 2, 5, the roller 5 rises in accordance with the thickness of the paper sheet P and a displacement signal (Sp) is outputted from the sensor 7. The thickness of the paper sheet P is calculated from the data Sp, So. By this method, even when the sensor 7 changes with the elapse of time, measuring accuracy is kept high.

Abstract: PURPOSE:To ensure the compensation for the light emitting delay of the output light of the laser diode by increasing the pulse duration of the pulse formation frequency modulation signal by the time of the light emitting delay of the output light of the laser diode, thus improving the frequency characteristics. CONSTITUTION:The frequency modulation signal sent from input end 2 is converted into the pulse formation frequency modulation signal via pulse formation circuit 3.

After this, the signal is supplied to driving circuit 4. Diode 5 receives the modulation  with this pulse featuring the incrased duration, but the optical pulse duration is decreased by the delay time difference of the rise points between the driving currents and the output light. Thus the optical pulse can be obtained with the duration which is nearly equal to that of the output pulse of circuit 3.
