DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ID card on which specific code information is recorded .

[0002]

2. Description of the Related Art Conventionally, this kind of ID card has been used in a wide range of applications such as a room key for unlocking a door locked by an electronic lock, a member's card, and the like. When using a card, the unique identification data recorded on the card is read by a card reader, collated with the identification data registered in advance, and if they match, the card is recognized as a legitimate card and unlocked by a specified method such as unlocking. Control or acknowledge use by members.

As the unique identification data, it is generally known that a magnetic sheet 37 is attached to one surface of an ID card 36 as shown in FIG. 9 and magnetically recorded on the magnetic sheet 37.
Such an ID card records a large amount of data because it is recorded as magnetic data, but a special writer is required for recording, and it is recorded that the ID card is owned by a strong magnetic field. There is a problem that the magnetic data is destroyed. Therefore, some of the cards are embossed, and important identification data is recorded as an embossed code 38 in an auxiliary manner. However, the appearance of the card is impaired, and special equipment for recording the identification data is required. And Furthermore, once embossed card,
There was a problem that it could not be reused.

In order to solve the problem of magnetic data being destroyed by a magnetic field, an ID card is also known in which a bar code label is attached instead of the magnetic sheet 37 and unique identification data is recorded with the bar code. But JAN, E
It is necessary to encode identification data in accordance with a predetermined code format such as AN, NW7, and similarly, a dedicated writer is required, and the amount of data that can be recorded is limited. Further, since the barcode label is attached to the ID card so as not to be easily detached, the card cannot be reused.

[0005]

The problem to be solved is that the recording of the unique identification data on the ID card requires a dedicated writer, which increases the cost and makes it easy to record the identification data once. This is because the data cannot be rewritten and the card cannot be reused.

If an attempt is made to record a large amount of data by magnetic recording, the data may be destroyed in a strong magnetic field. The point is that the amount of data that can be obtained is significantly restricted.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. FIG. 1 shows an ID card according to the present invention.
In the card body 1, a timing signal generation area 4 and an identification mark signal generation area 8 are formed.

The ID card body 1 is made of a rectangular thin plate made of plastic such as translucent acrylic.

The timing signal generation area 4 is formed along one long side of the ID card main body 1, and a pattern sense line 41 scanned by a timing mark reading unit 10 described later is provided in the timing signal generation area 4.
Pass through. Pattern sense line 4
On 1, timing marks 3 composed of eight bars are printed so as to be orthogonal to the pattern sense lines 41 at regular intervals. A start mark 5 and a stop mark 6 are printed on both sides of the timing mark 3 on the pattern sense line 41 in the reading direction. The start mark 5 and the stop mark 6 are square, and the mark width crossing the pattern sense line 41 is the timing mark 3
Are wider than each mark width. The marks 3, 5, and 6 in the timing signal generation area 4 are printed on the timing signal generation area 4 with opaque ink, and a sheet or plate on which the marks 3, 5, and 6 are displayed in advance is attached to the timing signal generation area 4. It may be stuck on.

The identification mark signal generation area 8 may be formed on any of the front and back surfaces of the ID card body 1 as long as it does not overlap with the timing signal generation area 4. The periphery of the identification mark signal generation area 8 is preferably displayed by a drawing area line 81 so that the identification mark 7 is not erroneously drawn in the timing signal generation area 4. An arbitrary identification mark 7 is drawn in the identification mark signal generation area 8, and the identification data of the ID card is registered. The identification mark 7 is drawn by using, for example, a black opaque ink felt pen or the like. The identification mark 7 is drawn with erasable ink.
It is possible to easily change the identification data of the ID card.
In this case, it can be reused as another ID card.

In the identification mark signal generation area 8, two pattern sense lines 82 and 83 which are scanned by an identification mark reading unit 11, which will be described later, cross, and the identification mark 7 is optically read.

FIG. 2 shows the above-mentioned ID card according to the present invention.
An ID recognizing device for reading an ID is composed of a timing mark reading section 10, an identification mark reading section 11, a binarization circuit section 15, a storage section 20, and a collation section 26.

The timing mark reading section 10 includes a set of a light emitting element 12c, a light receiving element 13c, and an amplifier circuit 14c for amplifying a detection signal photoelectrically converted by the light receiving element 13c. The light emitting element 12c and the light receiving element 13c are arranged opposite to the card insertion guide groove insertion opening of the ID card reader 9 so that the light from the light emitting element 12c is received by the light receiving element 13c.

The light receiving signal detected by the light receiving element 13c is converted into an electric signal and amplified by an amplifier circuit 14c connected to the output side of the light receiving element 13c.

The identification mark reading section 11 comprises two sets of light emitting elements 12a and 12b, light receiving elements 13a and 13b, and amplification circuits 14a and 14b for amplifying the detection signals photoelectrically converted by the light receiving elements 13a and 13b. .

Light emitting elements 12a and 12b and light receiving element 13
Reference numerals a and 13b also oppose each other near the insertion slot of the card insertion guide groove of the ID card reader 9 so that the light from the light emitting element is received by the light receiving element. The light reception signal detected by the light receiving element is converted into an electric signal, and is amplified by the amplifier circuits 14a and 14b connected to the output side of the light receiving element.

Both the light emitting element 12 and the light receiving element 13 are I
The light emitting element 12a and the light receiving element 13a are disposed on a pattern sense line 82, the light emitting element 12b and the light receiving element 13b are disposed on a pattern sense line 83, The light receiving element 12c and the light receiving element 13c are located so as to scan on the pattern sense line 41, respectively.

In this embodiment, the identification mark is scanned using the two sets of light emitting elements 12a and 12b and the light receiving elements 13a and 13b. However, the present invention is not limited to this. One set or three or more sets for improving recognition accuracy The light emitting element and the light receiving element described above can also be used. By increasing the number of pattern sense lines of the identification mark, the amount of identification data can be increased.

As the light emitting element, an LED, a cold cathode ray tube, a lamp or the like is used, and as the light receiving element, an image pickup element such as a photodiode, a phototransistor, or a CCD is used.

The binarizing circuit section 15 includes binarizing circuits 15a, 15b and 15c for converting a read signal into a binary signal, and a reference period correcting section for correcting the time width of the binary signal.

The binarization circuits 15a, 15b and 15c convert the read signals amplified by the amplifier circuits 14a, 14b and 14c into binary signals according to predetermined threshold values as shown in FIG. At the mark portion of the ID card, the light receiving element does not receive light from the light emitting element, so that the binary signal is at the L level. On the other hand, in the space where there is no mark, the light receiving element receives light from the light emitting element transmitted through the translucent substrate, so that the binary signal becomes H level.

FIG. 3 shows a read waveform (a) of the timing mark reading unit 10 which scans the timing signal generation area 4 and a binary signal (b) obtained by binarizing the read waveform. In the binary signal (b), the level becomes L level at each position of the start mark, the timing mark, and the stop mark, and the time width is longer because the start mark and the stop mark are wider than the timing mark. Also, since the eight timing mark intervals are equal,
The periods between the timing marks also appear to be equal.

The binary signal (c) output from the binarizing circuit
(D) shows that the identification mark signal is transmitted through the input port to the CP.
Sent to U.

The reference period correction unit comprises a period counter 16 for measuring the period of the binary signal (e), a transmitter 17 and a CPU 21 for correcting the period of the binary signal. If the scanning speed of the ID card changes when the ID card body 1 is read, or if the ID card body 1 is deformed, the time width of the read signal changes and the identification data of the ID card cannot be recognized correctly. .

The reference period corrector performs a normal reading operation,
Utilizing the fact that the binary signal (b) due to the timing mark changes at equal intervals as shown in FIG. 3, when the abnormal reading is detected, this is detected and the period of the binary signal (e) is set to the normal time. The width is corrected.

FIG. 4 shows the identification mark signals (c) and (d) and the timing mark signal (e) when the scanning speed becomes slow in the middle part of the ID card and abnormal reading is performed. This indicates that the scanning speed has been reduced from the timing mark, and the period t1 between the timing marks has become longer than the reference period t.

The output of the binarization circuit 15c is the period counter 1
6, the period counter 16 counts the clock signal output from the transmitter 17 from the fall of the timing mark signal (e) (when the level changes from the H level to the L level) to the next fall, The period between timing marks is measured.

The cycle counter 16 outputs a count value to the CPU 21 every time a fall occurs, resets the count value, and starts counting clock signals until the next fall.

Based on the count value output from the cycle counter 16, the CPU 21 compares the cycle between the falling edges of the timing mark signal (e) with the reference cycle t, and calculates a time width correction value between the timing marks.

As shown in FIG. 4, if the period from the third to the fourth timing mark is t1, the correction value is
t / t1.

In a section T corresponding to the identification mark signals (c) and (d) and the timing mark signal (e) input through the input port, the time width is compressed by t / t1. At the same time, when the cycle of the timing mark signal (e) input to the CPU 21 is different from the reference cycle t, the above-described correction is repeated for each section. The reference period t is assumed to be a period between timing marks of the timing signal (e) when a normal reading operation is performed, and is determined by, for example, obtaining an average value from an experimental value.

The storage unit 20 comprises a RAM connected to the CPU 21 via a bus line. However, the storage unit is not limited to the RAM, and may be an external storage device such as a floppy disk, CD-ROM, or optical disk connected via an interface.

The storage section 20 receives the write command from the CPU 21 and receives the identification mark signal (c) whose time width has been corrected.
The image data composed of (d) and the timing mark signal (e) is stored in the two-dimensional image memory as the ID card identification data as shown in FIG.

In FIG. 5, D1 is the binary data of the identification mark signal (c) read by scanning the pattern sense line 82, and D2 is the binary data of the identification mark signal (d) read by scanning the pattern sense line 83. The data D3 is binary data of the timing mark signal (e) read by scanning the pattern sense line 41.

Writing to the storage section starts after the start mark 5 is recognized, that is, when the data of D3 changes from "0" to "1", and ends before the data corresponding to the stop mark 6.

The collating unit 26 is connected to the above-mentioned CPU 21 and RA.
M20, an output interface 22, and an external storage device 23 connected via the output interface 22.

The external storage device 23 stores, as registration data, identification data output from the storage unit 20 in the initial registration mode when an ID card is issued.

The CPU 21 reads the ID card and stores the identification data temporarily stored in the storage unit 20 and the external storage device 23.
Calls the identification data registered in, and compares them. The CPU 21 outputs a control signal to the control device 24 according to the collation result, and instructs the display device 25 to display the collation result and the like.

The processing operation of the ID card recognizing device thus constructed will be described with reference to the flowchart of FIG.

Before reading the ID card, the ID card determines whether it is in the “recognition mode” in which the ID card is compared with the ID card already registered or in the “initial registration mode” in which the identification data of the ID card is initially registered. The CPU 21 is notified by a mode setting switch (not shown) of the recognition device. (Step S1)

Next, when the ID card main body 1 is inserted into the card insertion groove in the ID card reader 9 of the ID card recognition device, a microswitch (not shown) operates to detect the ID card insertion. As a result, the light emitting element starts emitting light, and the circuit of each block enters the reading standby mode. (Step S2)

Subsequently, when the ID card body 1 is moved along the card insertion groove, two sets of light emitting elements 12a and 12b and light receiving elements 13a and 13b are connected to the pattern sense lines 82 and 8 respectively.
3. Read the identification mark on 3. At the same time, the light emitting element 12c and the light receiving element 13c sequentially read the start mark 5, eight timing marks 3, and stop marks 6 on the pattern sense line 41. Each of the read detection signals is amplified by an amplifier circuit and then binarized by a binary circuit. (Step S3)

Each cycle of the timing mark signal (e) of the binary signal is measured by the cycle counter 16. C
The PU 21 compares each cycle with the reference cycle t, and corrects the identification mark signals (c) and (d) and the timing mark signal (e) binarized in step S3 so as to match the reference cycle t. (Step S4)

The image data consisting of the corrected identification mark signals (c) and (d) and the timing mark signal (e) is stored in the storage unit 20 as the unique identification data of the ID card.
Store in AM. (Step S5)

The CPU 21 sets the I set in step S1.
"Initial registration mode" or "Recognition mode" of D card
If it is in the “initial registration mode”, the process from step S7 onward is performed, and if it is in the “recognition mode”, the process from step S9 onward is performed. (Step S
6)

In the case of the “initial registration mode”, the identification data stored in step S 6 is stored in the external storage device 23 via the output interface 22. (Step S7)

When the storage is completed, the display 25 indicates that the registration has been completed, and the operation ends. (Step 8)

On the other hand, in the connection in the "recognition mode", the identification data registered from the external storage device 23 is called (step S9), and the recognition data stored in the RAM 20 is compared in step S7. (Step S10)

If they match, it is recognized as a registered ID card, and a display indicating the match is displayed on the display device 25 and a predetermined control controlled by the ID card such as unlocking of the electronic lock is instructed to the control device 24. (Step S11)

In addition, as a result of the collation, when the combination is determined to be inconsistent, the operation returns to before the operation is started so as to perform the reading operation again. (Step S12)

FIG. 7 shows another embodiment of the ID card according to the present invention. The ID card body 30 is a rectangular light-shielding thin plate. On the surface of the ID card body 30, a rectangular drawing area frame 32 representing a drawing area of the identification mark is printed. The drawing area frame 32 extends along one side of the drawing area frame 32.
, A start mark 33, eight timing marks 34, and a stop mark 35 are printed.

When the drawing area is clearly defined by the drawing area frame 32 in this manner, there is no possibility that an identification mark is drawn by mistake in the timing signal generation area 4, and the timing mark 34 forms a part of the drawing area frame 32. Since it looks as if it is configured, the beauty of the ID card is not spoiled.

The ground color of the surface of the ID card main body 30 is white, and these marks 33, 34, and 35 are printed with, for example, black ink whose brightness is completely different from white.

The reading of the ID card main body 30 is performed by reflecting light from the light emitting element 12 on the surface of the ID card and detecting the light by the light receiving element 13 disposed on the light emitting element 12 side. Therefore, a photo reflector or the like in which the light emitting element 12 and the light receiving element 13 are unitized is used for the reading unit.

FIG. 8 shows a third embodiment of the ID card, in which the timing signal generation area 40 is printed on the side surface of the ID card main body 42. By providing the timing signal generation area 40 on the side surface, the identification mark signal generation area 41 on the front surface can secure a sufficient drawing area, and the drawn identification mark overlaps the timing signal generation area 40, thereby causing an error. No timing mark signal is generated.

In reading the ID card body 42,
Recognition mark reading unit 11 and timing mark reading unit 1
Numerals 0 are arranged on inner surfaces of the ID card insertion grooves of the ID card reader which are orthogonal to each other.

[0063]

As described above, according to the present invention, since the identification data of the ID card is read optically, the identification data is not destroyed even if the ID card is erroneously placed near a strong magnetic field. .

Further, the identification data of the ID card can be recorded only by drawing the identification mark on one side of the ID card.
When the D card is initially registered, a dedicated writer for recording identification data is not required.

Furthermore, since the identification mark arbitrarily drawn is used as the identification data as image data, there is no restriction on the amount of data information as in the case of bar codes, and there is no danger of misuse because it cannot be reproduced.

Further, since a plurality of timing marks and identification marks are located in parallel along the reading direction of the ID card, the moving speed of the ID card changes when reading the ID card, or the ID card is deformed. Even so, the identification mark can be accurately recognized by using the timing mark as a reference.

Furthermore, since the identification mark is drawn with erasable ink, the identification mark can be erased and different identification data can be recorded, so that the ID card can be reused and is economical.
