Abstract

PURPOSE:To facilitate the positioning for reading of a bankbook and to improve the reading accuracy for a reading device using an optical sensor, by comparing the read data given from a reading part with a prescribed pattern data when a medium is inserted. CONSTITUTION:A stripe pattern which is drawn orthogonally to the traveling direction of an optical sensor 3 is applied on the suface of a press roll 2. This pattern is read by the sensor 3 when no bankbook is inserted and stored in a memory 6, and a stripe pattern signal P is stored. Therefore the coincidence is always obtained between a read signal A1 and the signal P. When a bankbook B reaches under the sensor 3, the insertion of the book B is detected since a detecting signal A2 is different from the pattern signal extracted from the memory 6. Then the shift amount is decided to the next print 4 by the detection of the book B.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Technical Field of the Invention The present invention relates to a reading device for reading bankbooks using optical reading means.

(b) Conventional technology and problems In the bookkeeping device, correct positioning is required in order to convey the passbook inserted from the reading unit to the printing unit and print it. Calculate the difference between the reading signal A, (focus level: when no passbook is inserted) and A, (white level: when passbook is inserted) of the optical sensor of the reading section,
A method of detecting insertion of a bankbook (this detection signal is used as a reference for positioning) is adopted. In this conventional method, even if the end of the passbook is detected, there may be a time lag in the detection, or the passbook may be soiled or there may be a difference in level due to lighting in the reading section. It was difficult to raise it. Therefore, it is necessary to install a transmission type reference sensor separately from the optical sensor of the reading section, and even if this means is provided, there is a drawback that reading accuracy cannot be improved.

(c) Object of the invention The present invention has been made to solve the above-mentioned drawbacks.
The purpose of the present invention is to provide a reading device that facilitates positioning of a passbook reader.

(d) Eleventh Arrangement of the Invention The present invention provides a device that includes a reading section having a light-year sensor and reads the surface of a medium inserted into the reading section using an optical sensor, which is provided at a position opposite to the optical sensor. a button surface having a predetermined button pattern; a storage section for storing the predetermined button data read by the reading section when the ρ'7 body is not inserted; and the data in the storage section and the reading section. means for comparing and identifying data read from the reading unit, when the medium is inserted into the reading unit, the data read from the reading unit is compared with the predetermined data stored in the storage unit; The reading device is characterized in that it detects insertion of the medium when.

FIG. 1 is a block diagram explaining one embodiment of the reading section of the present invention, FIG. 2 is a block diagram explaining one embodiment of the present invention, and FIG. 3 is a time chart explaining one embodiment of the present invention. , Fig. 4 is a front view of the bankbook, 1 is a conveyance section, 2 is a presser, 3 is an optical sensor, 4 is a printing section, 5 is a platen, 6 is a memory, 7 is a comparison section, 8 is a timing section, 9 is an AND circuit, 10 is a counter, 11 is a main control section, 12 is a pulse motor control section,

M1b is a scanning clock signal, TM2. 'l'M3 is a timing signal, and L11t is a time. In the eleventh row 1, the passbook Bii is sent to the right through the transport section 1 by transport rollers R3 and R2, and reaches between the optical sensor 3 and the holding roller 2. The irradiated light from the lamps L and 2 is reflected by the passbook B and read by the optical sensor 3, thereby detecting the insertion of the passbook. The optical sensor 3 is supplied with a scanning start signal TM1a and a scanning clock signal TM1b as shown in FIGS. 3(a) and 3(b) to perform scanning detection.

In the conventional method, the irradiated light from the lamps L1 and 2 is reflected by the holding roller 2), the p level signal detected by the optical sensor 3 (when no passbook is inserted), and the reflection from the passbook B when the passbook is inserted. The insertion of a bankbook was detected using the difference in accuracy between the white level signal and the detected white level signal. In the present invention, for example, a striped pattern of black and white, for example, a striped pattern drawn in a direction (vertical) perpendicular to the flight (horizontal) direction of the optical sensor 3 is applied to the surface of the holding roller 2. I'll keep it. Therefore, when the passbook is not inserted, the irradiation light from the lamp L, the holder, and the handle are irradiated onto the striped pattern on the holding roller 2, and the scanning (horizontal) detection by the optical sensor 3 reads this striped pattern. It will be done. This read signal A is stored in the memory 6, so
A striped bang signal P is stored. Therefore, when no passbook is inserted, the signal read successively from the optical sensor 3 and the signal taken out from the memory 6 always match, so no signal is output from the comparing section 7. The signal level of signal C'MPNG is "0".

However, when passbook B reaches the bottom of optical sensor 3, lamp L
The irradiated light from L and R (since it is reflected by passbook B, this detection signal A2 and the slam signal I taken out from memory 6) will be 4, so 7Jj of book B] One person will be detected. This communication Qll, (by detection of B, 0 sending to next print 4 (line 7 to be printed next)

FIG. 2 is a block diagram illustrating the control≦11 operation.
