It is a figure which shows the flow of the process performed by the information reading device of FIG.

FIG. 1 shows an example of the configuration of an information processing system for explaining an embodiment of the present invention.

The information processing system 1 includes an information holding medium 2 provided with a digital code, and an information reading device 3 for reading the digital code provided to the information holding medium 2.

The information reading device 3 is provided with a mounting portion 4 on which the information holding medium 2 is mounted, and the mounting portion 4 has an insertion opening 4 a opened on the side surface of the information reading device 3. The information holding medium 2 is inserted into the mounting portion 4 through the insertion port 4a and mounted in the mounting portion 4. Then, the information reading device 3 reads the digital code of the information holding medium 2 mounted in the mounting portion 4.

FIG. 2 shows the configuration of the information storage medium 2.

The information holding medium 2 has a medium base material 10 and an array of unit data parts 11. The array of the unit data part 11 holds a digital code. In the illustrated example, the medium base material 10 is a substantially circular plate-shaped hard member, but its shape and material are not particularly limited.

Grooves 12 are formed on the back surface 10 a of the medium base material 10. The groove 12 is provided so as to extend along an arbitrary diameter of the medium base material 10, and both ends thereof reach the side edges of the medium base material 10. The groove 12 defines the insertion direction of the information holding medium 2 into the mounting portion 4 when the information holding medium 2 is mounted in the information reading device 3.

The unit data portion 11 is arranged on the bottom surface of the groove 12 and is arranged two-dimensionally in the first direction and the second direction substantially orthogonal to the first direction. The second direction in the arrangement of the unit data part 11 is the same as the extending direction of the groove 12. In the illustrated example, the unit data units 11 are arranged in 4×4, but the number of unit data units 11 installed in each of the first direction and the second direction is not particularly limited.

Hereinafter, the first direction in the array of the unit data part 11 will be referred to as the X direction, and the second direction will be referred to as the Y direction.

A mark 13 for forming a digital code is formed in part of the unit data portion 11. In the illustrated example, the mark 13 is configured as a convex portion having a predetermined height, and binary data of “1” or “0” is given to the unit data portion 11 depending on the presence or absence of the mark 13, respectively. As a result, a digital code is formed in the array of the unit data part 11.

FIG. 3 shows an example of the mark pattern formed in the array of the unit data part 11. Note that FIG. 3A shows a mark pattern by the physical arrangement of the marks 13, and FIG. 3B shows that the presence or absence of the marks 13 is replaced with binary data of “1” or “0”. The mark pattern is indicated by the digital code.

Each of the unit data part rows 14a, 14b, 14c, 14d formed by the four unit data parts 11 arranged in the X direction is configured to include at least one mark 13.

The mark patterns in the X-direction permutation of two unit data part rows adjacent to each other in the Y-direction arrangement of the unit data part strings 14a, 14b, 14c, 14d are different from each other. For example, the mark pattern in the X-direction permutation of the unit data part sequence 14a is "Yes, No, Yes, Yes", and the corresponding data string is "1, 0, 1, 1". The mark pattern of the X-direction permutation is “absent, present, present, absent”, and the corresponding data sequence is “0, 1, 1, 0”, which are different from each other.

Further, the mark pattern of the unit data part sequence 14a, 14b, 14c, 14d arranged in the Y direction in the X direction permutation of the unit data part sequence 14d on one end side is a specific mark pattern common to a plurality of types of digital codes. ing. The specific mark pattern and the corresponding data string represent the end of the digital code formed in the array of the unit data part 11. In the illustrated example, the mark pattern in the X-direction permutation of the unit data part sequence 14d is “Yes, No, Yes, No”, and the corresponding data sequence is “1, 0, 1, 0”.

Hereinafter, the unit data portion 14d will be referred to as a terminal side unit data portion sequence, and the other end side unit data portion sequence 14a will be referred to as a start end side unit data portion sequence.

The mark pattern in the X direction permutation of the starting end side unit data part sequence 14a is different from the mark pattern in the X direction permutation and the mark pattern in the −X direction permutation of the end side unit data part sequence 14d.

Further, the mark pattern of the X-direction permutation of the unit data part sequences 14b and 14c is also different from the mark pattern of the X-direction permutation and the -X direction permutation of the terminal-side unit data part sequence 14d.

The information holding medium 2 is inserted into the insertion port 4a of the information reading device 3 with the starting end side unit data portion sequence 14a at the head, and is attached to the attachment portion 4.

FIG. 4 shows the configuration of the information reading device 3.

Two ridges 20 are formed on the mounting portion 4 of the information reading device 3. These two ridges 20 are provided so as to extend in a direction parallel to the Y direction in the arrangement of the unit data portions 11 when the information holding medium 2 is attached to the attachment portion 4, and are provided on the medium base material 10. It engages with both sides of the formed groove 12. Thereby, the insertion direction of the information holding medium 2 into the mounting portion 4 is defined in the Y direction.

The mounting unit 4 is provided with a detection unit 21 that detects the marks 13 formed on the array of the unit data units 11 of the information holding medium 2 and outputs a signal according to the detection result of the marks 13. The detection units 21 are provided in the same number as the number of the unit data units 11 forming one unit data unit row, and when the information holding medium 2 is mounted on the mounting unit 4 between the two ridges 20. Are arranged in a direction parallel to the X direction in the arrangement of the unit data part 11.

In the illustrated example, the detection unit 21 is configured as a switch that is pressed by the mark 13. When the mark 13 passes over the detection unit 21 as the information holding medium 2 is inserted into or removed from the mounting unit 4, the detection unit 21 is pressed by the mark 13 and automatically after the mark 13 passes. Surface. Then, the detection unit 21 outputs a High level signal when it is pressed, and outputs a Low level signal when it is in a floating state.

Then, as the information holding medium 2 is inserted into or removed from the mounting section 4, the unit data section rows 14a, 14b, 14c, 14d sequentially pass over the rows of the detection sections 21. Every time one unit data section row passes through the row of the detection units 21, a signal is output in synchronization from the group of the detection units 21.

FIG. 5 shows functional blocks of the information reading device 3.

The information reading device 3 acquires a signal output from the group of the detection units 21 and recognizes the digital code of the information holding medium 2, and supplies power to the processing unit that executes various processes and each unit of the information reading device 3. And a power supply unit 22 for supplying power. The processing unit includes an operation unit 23, a storage unit 24, and a control unit 25.

The operating unit 23 is configured to be able to output an effect including at least one of, for example, sound and light emission. In the illustrated example, the operation unit 23 is configured to include a speaker 26 and capable of outputting an effect by voice.

The storage unit 24 includes a storage medium such as a ROM (Read Only Memory) or a RAM (Random Access Memory), and includes a program executed by the control unit 25, various digital codes added to the information storage medium 2, and an operation unit. A table and the like in which various audio data to be output to 23 are associated with each other are stored.

The control unit 25 includes a processing device such as a microprocessor, operates according to a program stored in the storage unit 24, and controls the operation of each unit of the information reading device 3.

The control unit 25 assigns digital data corresponding to the signals to each of the signals that form the unit signal group, with the signal group that is synchronously output from the group of the detection units 21 as one unit, and assigns the assigned data. A data string is generated by arranging according to the X-direction permutation of the detection unit 21.

In this example, the detection unit 21 is configured to output a High level signal when pressed by the mark 13 and a Low level signal when the mark 13 is floated up. The signal level of the signal output from 21 is discriminated, and "1" data is assigned when the signal level is the High level, and "0" data is assigned when the signal level is the Low level. Therefore, for example, a data string of "1, 0, 1, 1" is generated for the mark pattern "Yes, No, Yes, Yes" of the X-direction permutation of the starting end side unit data section string 14a (see FIG. 3). ).

Here, as described above, each of the unit data part sequences 14a, 14b, 14c, 14d is configured to include at least one mark 13, and the mark pattern of the two adjacent unit data part sequences in the X direction permutation. Are different from each other. Therefore, when the mark patterns of two adjacent unit data part rows are respectively detected by the group of the detection parts 21, at least one is output from the detection part 21 between the two adjacent unit data part strings. The signal will change.

The control unit 25 detects the switching of the signals output from at least one detection unit 21, acquires the signals output in synchronization from the group of the detection units 21 at the timing when the signals are switched, and generates a data string. .. As a result, the control unit 25 can accurately recognize the boundaries of the unit data unit rows 14a, 14b, 14c, and 14d without being separately instructed on the timing of acquiring the signals output from the group of the detection units 21. A data string can be generated for each data section string.

A memory area having a capacity of three data rows is secured in the storage section 24, and the control section 25 is sequentially obtained for each unit data section row as the information holding medium 2 is inserted into the mounting section 4. The data string is stored in the memory area secured in the storage unit 24. For example, when the information holding medium 2 is inserted into the mounting portion 4 with the starting end side unit data section sequence 14a at the head, three storage sequence data rows are sequentially obtained from the unit data section sequence 14a, 14b, 14c. It is stored in 24 memory areas.

Then, the control unit 25 detects the data string “1,0,1,0” corresponding to the specific mark pattern “Yes, No, Yes, No” in the X-direction permutation of the terminal-side unit data section string 14d. At that time, the digital code is recognized based on the data string stored in the storage unit 24, and the process corresponding to the recognized digital code is executed.

Hereinafter, the pattern of the data string “1,0,1,0” corresponding to the above-mentioned specific mark pattern “Yes, No, Yes, No” is referred to as an end data string pattern, and the permutation of the specific mark pattern is reversed. The mark pattern “absent, present, absent, present” is called an inverted specific mark pattern, and the pattern of the data string “0, 1, 0, 1” corresponding to the inverted specific mark pattern is called an inverted end data string pattern.

FIG. 6 shows a flow of processing executed by the control unit 25.

When the power of the information reading device 3 is turned on, the control unit 25 secures a memory area having a capacity of three data strings in the storage unit 24 and erases the data in this memory area (step S1).

As the information holding medium 2 is inserted into or removed from the mounting unit 4, a signal is output from the group of the detection units 21 that have detected the mark pattern for each unit data section row. The control unit 25 acquires the signals output from the group of the detection units 21 and generates a data string (step S2).

Next, the control unit 25 determines whether or not the data string matches the above inverted end data string pattern (step S3).

For example, when the information holding medium 2 is inserted into the mounting section 4 with the starting end side unit data section sequence 14a at the head, the mark pattern in the X direction permutation of the starting end side unit data section sequence 14a is first detected by the group of the detection sections 21. Although detected, this mark pattern is different from the above inverted specific mark pattern, and the data string is different from the above inverted end data string pattern.

On the other hand, when the information holding medium 2 is inserted into the mounting unit 4 with the end side unit data part sequence 14d at the head, the mark pattern of the −X direction permutation of the end side unit data part sequence 14d is detected by the detection unit 21. First detected by the group, this mark pattern matches the above inverted specific mark pattern and the data string matches the above inverted end data string pattern.

Therefore, when the data string matches the above-mentioned inverted end data string pattern, the control unit 25 executes the error process assuming that the information holding medium 2 is mounted in the mounting unit 4 in the reverse direction (step S4), The data in the memory area of the storage unit 24 is erased (step S5). As the error process, a process of operating the operation unit 23 based on voice data such as an error message stored in the storage unit 24 can be exemplified.

On the other hand, when the data string does not match the inverted end data string pattern, the control unit 25 determines whether the data string matches the end data string pattern (step S6).

Then, when the data string does not match the end data string pattern, the control unit 25 stores the data string in the memory area secured in the storage unit 24 (step S7).

For example, when the information holding medium 2 is inserted into the mounting section 4 with the starting end side unit data section sequence 14a at the head, the mark patterns of the X direction permutations of the unit data section sequences 14a, 14b, 14c are detected by the detection section 21. However, the mark patterns in the X-direction permutation of each of the unit data part sequences 14a, 14b, 14c are different from the specific mark pattern described above, and the unit data part sequences 14a, 14b, 14c are different from each other. The data string obtained from each of the above is different from the above end data string pattern. Therefore, the data strings sequentially obtained from the unit data part strings 14 a, 14 b, 14 c are stored in the memory area of the storage unit 24.

On the other hand, when the data string matches the above end data string pattern, the control unit 25 determines whether or not the memory area of the storage unit 24 is empty (step S8), and when the memory area is not empty, That is, when the data string is stored in the memory area, the control unit 25 subsequently recognizes the digital code based on the data string stored in the memory area (step S9), and the digital code is stored in the storage unit. Based on whether or not the digital code is included in the table stored in 24, it is determined whether or not the digital code is proper (step S10).

For example, the information holding medium 2 is inserted into the mounting section 4 with the starting end side unit data section sequence 14a at the head, and the data sequence sequentially obtained from the unit data section sequence 14a, 14b, 14c is stored in the memory area of the storage section 24. In this case, the end data string pattern is detected in the data string obtained from the terminal side unit data part string 14d upon completion of mounting the information holding medium 2 in the mounting part 4. At that time, data strings obtained from the unit data part strings 14a, 14b, 14c are stored in the memory area of the storage unit 24, and the digital code is recognized based on these data strings. This digital code is included in the table of the storage unit 24 as one of the digital codes given to the information holding medium 2, and is determined to be proper.

When the digital code is proper, the control unit 25 reads the voice data stored in association with the digital code from the storage unit 24 as the mounting effect process when the information holding medium 2 is mounted on the mounting unit 4. A performance process for operating the operation unit 23 based on the read voice data is executed (step S11), and the data in the memory area of the storage unit 24 is erased (step S12).

On the other hand, when the recognized digital code is not proper, the control unit 25 executes error processing (step S13) and erases the data in the memory area of the storage unit 24 (step S14).

If the digital code is not appropriate, the information holding medium 2 is reciprocated back and forth in the process of being inserted into the mounting section 4, and the unit data section sequence 14a and the unit data section sequence 14b are repeated a plurality of times by the group of the detection section 21. A case can be exemplified in which the data strings that have been detected and obtained from the unit data part sequence 14a and the unit data part sequence 14b are redundantly stored in the memory area of the storage unit 24.

When the information storage medium 2 is mounted on the mounting unit 4 and the information storage medium 2 is removed from the mounting unit 4 after the above-described mounting effect process (step S11) or error process (step S13) is executed, The mark pattern in the X-direction permutation of the terminal-side unit data section sequence 14d is first detected by the group of detection sections 21. The above-mentioned end data string pattern is detected in the data string obtained from the terminal-side unit data part string 14d, but at this time, the data is erased from the memory area of the storage section 24 to become empty (step S12, S14).

In this way, when the data string matches the end data string pattern described above and the memory area is empty, the control unit 25 executes the effect process when the information storage medium 2 is removed from the mounting unit 4. Then, the data in the memory area of the storage unit 24 is erased (step S15) (step S16). As the removal effect production process, a process of operating the operation unit 23 based on voice data such as a sound effect stored in the storage unit 24 can be exemplified.

The above-described removal effect process is performed when the information holding medium 2 is removed from the mounting section 4 after the information reading device 3 is powered on while the information holding medium 2 is mounted in the mounting section 4. Is also executed.

In the information processing system 1 described above, the mark 13 is configured as a convex portion having a predetermined height, and binary data is added to the unit data portion 11 of the information storage medium 2 depending on the presence or absence of the mark 13, The data given to the data section 11 is not limited to binary data. For example, it is possible to use marks having different heights and give three or more values of data to the unit data part 11 depending on the presence or absence of the mark and the mark height. The mark 13 may be any mark that can take a plurality of discrete values with respect to a specific physical quantity, and the mark 13 can be configured by coloring the unit data portion 11 with a color having a different reflectance, for example.
