Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a magnetic passbook reading device used in a magnetic passbook printing terminal device.

A magnetic passbook generally applied to a magnetic passbook printing terminal device of a bank or the like is constructed as shown in FIGS. 1a and 1b. That is, the passbook P is made up of a plurality of sheets of paper bound between the front and back covers, and each of these sheets is used as a printing medium. Each page is provided with a plurality of printing fields 1 at a pitch of ₁₂ , and a coded bar mark 2 is printed on the left back to identify each page. For example, if there is one bar mark 2 on one page, then there are two bar marks.
It is assumed that the page is printed in two pieces. A magnetic stripe 4 is pasted on the back cover 3, and magnetic data such as an account number, the number of printed pages, and a bankbook balance is recorded on this stripe 4.

FIG. 2 shows a conveying section and a reading section of a conventional magnetic passbook printing terminal device. In other words, passbook P
is inserted into the passbook insertion slot in the direction of arrow B in the figure, and taken into the device by conveyance rollers C.
D and E are guide plates, and the magnetic head F is in the direction of the arrow H shown in the figure (orthogonal to the moving direction B of the bankbook P and coincident with the direction of the magnetic stripe 4 of the bankbook P).
No guide plate is provided in the range of movement.

Thus, while the passbook P is moving, the magnetic head F comes into contact with the magnetic stripe 4 and reads (or writes) magnetic data. However, conventionally, only one set of magnetic data is recorded on the magnetic stripe 4, so if the contact timing between the magnetic head F and the magnetic stripe 4 is out of order for some reason, the magnetic data cannot be completely read, and the data cannot be read. There was a drawback that the rate decreased.

The present invention was made in view of the above circumstances, and
The data read rate can be increased by recording magnetic data of the same content in multiple blocks on the magnetic stripe by dividing it in the stripe length direction, and using the magnetic data of at least one block as read data if it is read normally. The present invention provides an improved magnetic passbook reading device.

EMBODIMENT OF THE INVENTION Hereinafter, a magnetic passbook printing terminal device to which an embodiment of the present invention is applied will be described in detail with reference to the drawings.

FIG. 3 shows a magnetic passbook P' applied to the device of the present invention, which is different from the passbook P described above with reference to FIG. , is different in that they are recorded separately in the second block. FIG. 4 shows a magnetic bankbook printing terminal device, in which reference numeral 10 is an entrance/exit for a bankbook P', and a bankbook transport path 19 is formed rearwardly from this entrance/exit 10 by a pair of rollers 15. This roller pair 15 is driven by a pulse motor 6
By inputting a predetermined number of pulses to the pulse motor 68, the passbook P' can be moved forward or backward by a distance corresponding to the number of pulses. In the middle of the passbook conveyance path 19, there is a shutter 13 that opens and closes by controlling the excitation of the solenoid 14 in order from the entrance/exit 10 side, and then a magnetic head 18 and a pressure plate 19' that read/write data on the magnetic stripe 4. A magnetic data reading/writing section 17 consisting of a magnetic data reading/writing section 17, next a page information detecting section 21 for detecting the passbook page mark and the last printed line of the page, and finally a printing section 26 consisting of a platen 27 and a print head 28 are provided. There is.
Note that the page information detection section 21 uses a lens 22
It consists of a photoelectric element 23 and an illumination lamp 24, which photoelectrically converts page surface information via a light source. moreover,
At a predetermined position in the middle of the passbook transport path 19, a passbook is provided.
A group of sensors is provided to optically detect the passage of the terminal end of P'. Here, sensor 1 in front of shutter 13
1 as SC1, and the sensor 16 in front of the magnetic head 18 as SC1.
2. SC the sensor 20 in front of the page information detection unit 21
3. The sensor 29 behind the platen 27 is called SC4. Note that the distance l ₁ between the page information detection unit 21 and the SC2 is configured to be equal to the distance from the rear end of the bankbook P' to the upper digit line of the first printing column.

Next, the configuration of the magnetic data reading/writing section 17 will be described in detail with reference to FIGS. 5 and 6. That is, the pair of conveying rollers 15 and the upper and lower guide plates 102, 103, 10 are mounted on the left and right side plates 100, 101.
4 is installed. The guide plate 102,
The gap 103 is a movement space for the magnetic head 18. The head 18 is fixed to a head block 105, which is fitted into a carriage block 106, and is urged upward by a spring 107 to move the passbook P' to the upper guide plate. 104. The carriage block 106 includes a guide rod 108 and a lead screw 109.
The guide rod 108 and the lead screw 109 are attached to the plates 110 and 111, and the lead screw 109 is attached to the pulley 112 and the belt 11.
3. Reversible motor 1 via pulley 114
15, thereby causing the carriage block 106 to reciprocate between the plates 110 and 111. Sensors 116 and 117 are respectively provided at the ends of the reciprocating movement of the carriage block 106, and if this is blocked by a plate 118 attached to the carriage block 106, a stop signal is issued to the reversible motor 115. Furthermore, 1
A movable guide plate 19 is rotatable about a shaft 120 and is connected to a rotary solenoid 123 via levers 121 and 122. When the solenoid 123 is energized, the movable guide plate 119 rotates downward from the conveying surface to create a space for the magnetic head 18 to move. Furthermore, when the solenoid 123 is de-energized, the force of the return spring built into the solenoid 123 causes the movable guide plate 119 to come out onto the conveyance surface and play the role of a conveyance guide. Furthermore, 124 is a detector located at an intermediate position between the sensors 116 and 117 so as to detect the point in time when the magnetic head 18 passes through the dividing point between the first block and the second block of the magnetic stripe 4 of the passbook P'. It is provided.

Next, the operation of the above configuration will be explained. First, the passbook P' is opened and inserted into the doorway 10, and when the SC1 detects the "dark" state, the shutter 13 is opened and at the same time the pulse motor 68 is driven in the passbook handling direction (forward rotation direction). and roller vs. 1
5, the passbook P' is taken into the conveyance path 19. Next, the pulse motor 68 is activated by a predetermined number of pulses by the inverted output of SC2 from the "dark" state to the "bright" state.
is driven, and the shutter 13 is closed at the same time as the pulse motor 68 is stopped. As a result, the passbook P' is located in the magnetic data reading/writing section 17 and the pressing plate 1
The information on the magnetic stripe 4 is read out by pressing the magnetic stripe 9' in the direction of the head 18 and scanningly driving the head 18, and stored in the storage section 75 via the magnetic information processing section 72. Next, the pulse motor 68 is reversed, and the timing of the reversal of the SC2 from the "bright" state to the "dark" state (at this time, the field of view of the page information detection unit 21 is on the upper digit line of the first print column of the passbook P'. ), the page mark 2 is detected by the page information detection section 21, and the pulse motor 68 is driven for a predetermined number of pulses, and then the pulse motor 68 is stopped.

Next, the pulse motor 68 rotates normally again, and SC2
The page information detection unit 21 detects the presence or absence of printing on each line of the passbook P' at the timing of the transition from the "dark" state to the "bright" state. The signal from the page information detection unit 21 is
The page information processing unit 71 converts the opened page into the page number and the last printed line. This last printed line and the magnetic stripe 4 read from the storage unit 75
The main control unit 73 compares the number of pages above, and if a match is found, the pulse motor 68 is once reversed and stopped by the inverted output of the SC3 from the "bright" state to the "dark" state, and then the SC3's "dark" state is stopped again. ” Status → “Bright”
The pulse motor 68 is rotated in the normal direction by a predetermined number of pulses for the next line of the last printed line to reach the printing position, which is determined in advance from the state reversal timing, and then stopped. At this time, SC4 always outputs a "dark" state, and if this is not the case, it is determined that the passbook P' is in a jammed state. Next, the transmission control section 74
Send the account number etc. to the center computer 76,
The center computer 76 reads the account information from the ledger file 77 and sends it to the transmission control unit 74.
In response to this, the print head 28 is operated via the print head control section 70 to print on the bankbook P'. At this time, if the information spans multiple lines of the passbook P', the pulse motor 68 is driven one line each time to change the line.

When printing is completed as described above, the pulse motor 68 is reversed again, and the SC2 changes from the "bright" state to the "dark" state.
It stops when the state is reversed, rotates normally again, and stops after sending a predetermined pulse from the timing of the reversal of SC2 from the "dark" state to the "bright" state. The passbook P' is stopped by the magnetic data reading/writing unit 17, and the magnetic stripe information is rewritten (the number of pages of the passbook P', the last printed line, the amount of balance entered in the passbook), and then the shutter 13
is opened, the pulse motor 68 is reversed, and a predetermined number of pulses are sent from the reversal timing of the SC2 from the "dark" state to the "bright" state, and then stopped. Passbook P′ is at entrance 10
When the user pulls it out, the SC1's "dark" state → "bright" state is inverted and the shutter 1 is activated.
3, and the series of processing ends.

Further, to describe the operation of the magnetic data reading/writing section 17 in detail, in the initial state, the carriage block 106 stops at a position that blocks the sensor 116, the rotary solenoid 123 is not excited, and the movable guide plate 119 is conveyed. It's on the surface.
In this state, when the passbook P' is inserted and stopped at the reading position of the magnetic stripe 4, the main controller 73 checks that the sensor 116 is in the "dark" state and then energizes the rotary solenoid 123. Next, the motor 115 is rotated to scan the magnetic stripe 4 while bringing the magnetic head 18 into close contact with the passbook P', thereby reading out the magnetic data. Then, the sensor 117 becomes "dark" and the motor 115 stops. This completes the reading, and the pulse motor 6
8 to convey the passbook P' to the next step, and at the same time, the excitation of the rotary solenoid 123 is released.

Next, when the printing of passbook P' is completed and the magnetic stripe 4 is stopped at the writing position to be rewritten,
The main control unit 73 again checks that the sensor 117 is in the “dark” state, and then turns on the rotary solenoid 1.
23 is excited. As a result, the movable guide plate 119 escapes downward again, and then the motor 115 is rotated in the opposite direction to the reading direction, the magnetic data is rewritten, and the "dark" state control signal of the sensor 116 causes the motor 115 to rotate.
is rotated in the reverse direction, the rewrite information is read out, and a rewrite check is performed. Motor 115 is sensor 117
Stops in the "dark" state. Next, the pulse motor 68 is reversed again, and at the same time the rotary solenoid 12
Release the excitation of 3.

Next, a read data processing circuit in the magnetic information processing section 72 is shown in FIG. The read output from the magnetic head 18 is subjected to analog processing by a quantization circuit 201, and converted into a quantized signal according to changes in the read output. Here, a bit extraction signal for each bit constituting the read data is further output according to the quantized signal, and a 1/0 determination is made for each bit according to the bit extraction signal, and the bit signal is output as a bit signal. Output. The serial/parallel conversion circuit 202 is constituted by a shift register, and converts the bit signal into 1/0 for each bit output as a serial signal from the quantization circuit 201 to form a character. It is read into a shift register in synchronization with the output signal, converted into parallel signals for each character, and output as character data. Starting character detection section 2
In step 03, characters are detected starting from the character data output from the serial/parallel conversion circuit 202. That is, a start character is written as the first character of the data, and the start of the data can be determined by detecting the start character. When a starting character is detected by the starting character detection section 203, a read data starting flip-flop 204 is set. Once read data start flip-flop 204 is set,
Bit counting circuit 205 starts operating. That is, the number of bits constituting a character is counted in synchronization with the bit extraction signal output from the quantization circuit 201. This count output (character cutout signal) is input to the main control section 73 and informs that the character data output from the serial/parallel conversion circuit 202 is configured as a regular character. The character data output from the serial/parallel conversion circuit 202 is input to the main control section 73, and the main control section 73 reads the character data according to the character extraction signal from the bit counting circuit 205. It becomes possible to read character by character. Reading of the first block is started as described above, and character data is sequentially sent to the main control section 73.

When the magnetic head 18 is reading the dividing point between the first block and the second block of the magnetic stripe 4 (position X in FIG. 3), the detector 124 outputs a passing detection signal of the magnetic head 18. This passage detection signal is quantized by a quantization circuit 206 according to brightness and darkness. The quantized output of the quantization circuit 206 is generated by the magnetic head 18 on the magnetic stripe 4.
When it is detected that the reading data has passed the dividing point, the read data start flip-flop 204 is reset.
When the read data start flip-flop 204 is reset, the bit counting circuit 205 stops operating and stops outputting the character extraction signal to the main control section 73. As a result, the main control section 7
3 interrupts reading of character data. On the other hand, the quantized output of the quantization circuit 206 is input to the main control section 73, and the main control section 73 controls the magnetic head 18.
It is determined that the magnetic stripe has passed the dividing point of the magnetic stripe 4, the processing for the first block is ended, and the processing for the second block is started. Reading of the second block starts by detecting the first character, which is the first character, as in the first block, and character data is input to the main control section 73 in the same manner.

In addition, in the above embodiment, the movable guide plate 11
9 and the fixed guides 102 and 103 are shown in the eighth figure.
By overlapping them in a comb-teeth shape as shown in the figure, a more reliable conveyance guide can be achieved.

As described above, the magnetic passbook reading device of the present invention handles a magnetic passbook in which the same magnetic data is recorded on the magnetic stripe divided into a plurality of blocks in the length direction of the stripe, and the magnetic head is placed in contact with the stripe. When the magnetic head is moved to read magnetic data, a detector is arranged to detect when the magnetic head passes a position where the magnetic head reads out the divided portion of the block. Based on the head passage detection output from this detector, the data read by the magnetic head is processed in units of blocks.

Therefore, even if the magnetic head starts reading from the middle of the stripe data due to misalignment of the magnetic passbook, it is only necessary that the magnetic head can completely read at least one block of the stripe data, so the data reading process will continue. It is possible to prevent the rate from decreasing.
