Description

  The present invention relates to an information acquisition system, and more particularly to an information acquisition system for acquiring information stored in a card.

  Conventionally, barcode systems have been widely used as systems capable of storing predetermined information. A bar code is information that is encoded by a combination of a black bar-shaped part having a different thickness and a blank part, and the code is optically read by a scanner, and the encoded information is decoded. It is possible to acquire information before encoding into a barcode. In order to increase the amount of information encoded using the barcode system, it is necessary to increase the number of digits of the barcode. However, the increase in the number of digits causes a problem in that the barcode arrangement becomes longer and reading by the scanner becomes difficult. At present, in order to solve these problems, a two-dimensional code system in which a plurality of black rectangular cells are two-dimensionally arranged according to a predetermined arrangement rule is becoming popular as an information encoding system replacing a barcode. The two-dimensional code can be read by an optical device such as a video camera.

[Card configuration]
FIG. 6 is a perspective view of the card 101 according to the present embodiment.

  The card 101 includes a plate-like portion 101a and a plurality of hole portions 101b formed in the plate-like portion 101a. The plate-like portion 101a is formed by resin formation or the like and is made of a material that hardly transmits light. The plate-like portion 101a has a first surface 101c and a second surface 101d that faces the first surface 101c. The second surface 101 is disposed to face the light sensing panel 107 when information is acquired from the card 101 (hereinafter referred to as card information acquisition). The hole portion 101b has a substantially circular shape in plan view, and is formed so as to penetrate from the first surface 101c to the second surface 101d of the plate-like portion 101a. The card 101 transmits light between the first surface 101c and the second surface 101d in the hole portion 101b, but does not transmit light in a portion of the plate-like portion 101a other than the hole portion 101b. The shape of the hole 101b is not limited to a substantially circular shape in plan view, and can be formed in an arbitrary shape.

  The plate-like portion 101a is divided into predetermined areas 101e, and each hole 101b is formed for each predetermined area 101e. Note that the hole 101b is not necessarily formed in each area 101e. In the present embodiment, the area 101e is configured to correspond one-to-one with the cell P of the light-sensitive panel 107.

  FIG. 7 is an explanatory diagram for explaining the principle of obtaining information from the card 101 according to the present embodiment. As shown in the figure, in the plate-like portion 101a (an area other than the hole portion 101b), the light output from the first display portion 105 is almost reflected by the plate-like portion 101a, and the corresponding cell of the light-sensitive panel 107 is displayed. In, almost no light is detected, and “0” is assigned. On the other hand, in the hole 101b, the light from the first display unit 105 passes through the hole 101b, and the light is detected well in the corresponding cell of the light sensing panel 107, and “1” is assigned.

  The card 101 stores information encoded based on the presence or absence of the hole 101b in each area 101e, that is, the position and number of the holes 101b. In other words, in the area 101e in which the hole 101b is formed, light incident from the first surface 101c side through the hole 101b is transmitted to the second surface 101d side (an area having a high transmittance), and the hole 101b In the non-formed area 101e, light incident from the first surface 101c side is blocked by the plate-like portion 101a and hardly transmits to the second surface 101d side (an area with low transmittance). As described above, in the present embodiment, information is stored in the card 101 and information is acquired from the card 101 based on the difference in light transmittance in areas with different transmittances on the card 101.

  In the present embodiment, the second surface 101 d of the plate-like portion 101 a is installed so as to face the light sensing panel 107 and information is acquired from the card 101. For this reason, the first surface 101c and the second surface 101d of the plate-like portion 101a are configured so that the user can distinguish and visually recognize them. For example, characters such as “Please install with this side down” and symbols such as stars are provided on the second surface 101d. Further, the colors of the first surface 101c and the second surface 101d may be different from each other.

  Acquisition of information from the card 101 is performed by placing the second surface 101d of the card 101 on the light sensing panel 107, and in this state, the first housing 103 and the second housing 104 are closed as shown in FIG. Put it in a state. Then, the first display unit 105 is caused to emit light, and the light output from the first display unit 105 is detected by the light sensing panel 107 through the hole 101 b of the card 101. In this manner, the coordinate data of the hole 101b of the card 101 is acquired by the light sensing panel 107, and the information stored in the card 101 is decoded based on the position and number of the hole 101b obtained from the coordinate data. .

[Information acquisition method]
8 and 9 are flowcharts related to the information acquisition method according to the present embodiment.

  The following processing is performed by the CPU 112 executing an information acquisition program stored in the memory 113 of the electronic device 102. The information acquisition program may be stored in the recording medium 114a or acquired from the network by the communication unit 116.

  After inputting the switching of the card information reading mode from the operation key 108, the card 101 is installed on the light sensing panel 107 of the electronic device 102 as shown in FIG. 1B, and the electronic device 102 is shown in FIG. In the closed state shown, the electronic device 102 starts acquiring information from the card 101. The card 101 is installed such that the second surface 101d faces the light sensing panel 107.

  In step S101, the CPU 112 determines whether or not switching from the operation key 108 to the card information acquisition mode has been accepted. CPU112 transfers to step S102, when the switch to card information acquisition mode is received. CPU112 repeats the process of step S101, when switching to card information acquisition mode is not received.

  In step S <b> 102, the CPU 112 outputs an instruction image for instructing installation of the card 101 on the light sensing panel 107 to the second display unit 106. This instruction image is, for example, “Place card here”. The instruction image may be output to the first display unit 105. The instruction image in this case is, for example, “Place the card on the lower screen”.

  In step S103, the CPU 112 determines whether or not the electronic device 102 is in the closed state shown in FIG. If the CPU 112 has not received the detection signal from the open / close sensor 117, the CPU 112 determines that the electronic device 102 is in the open state and proceeds to step S <b> 101. On the other hand, when the user installs the card 101 on the light sensing panel 107 and closes the electronic device 102 in response to the display in step S102, the CPU 112 receives a detection signal from the open / close sensor 117. At this time, the CPU 112 receives a detection signal from the open / close sensor 117 and proceeds to step S104.

  In step S104, the CPU 112 causes the first display unit 105 to emit light. For example, the CPU 112 causes the entire screen of the first display unit 105 to emit light in white. The first display unit 105 may emit light in any display color as long as it emits light with a brightness that can be detected by the light sensor of the light sensing panel 107.

  In step S105, the CPU 112 acquires the detection value of the optical sensor for each cell P from the photosensitive panel 107, and creates the coordinate data of the hole 101b as shown in FIG. The position and number of the hole 101b are obtained from this coordinate data.

  FIG. 10 is a flowchart for explaining the processing in step S105.

  The CPU 112 sequentially applies a scanning signal to the data electrode S (step S201), acquires the detection value of the photosensor for each cell from the data electrode G (step S202), and whether the detection value is greater than or equal to a predetermined threshold value for each cell P. It is determined whether or not (step S203). If the detected value of the cell P is greater than or equal to the threshold value, “1” is assigned to the cell P and stored in the memory 113 (step S204). On the other hand, if the detected value of the cell P is less than the threshold, “0” is assigned to the cell P and stored in the memory 113 (step S205). Each time the processing of steps S201 to S205 is completed for each scan electrode S, it is determined whether or not data ("1" or "0") has been assigned to all cells P (step S206). If it is assigned, the process is terminated. If there is a cell P to which no data is assigned, the process returns to step S201, and the process of steps S201 to S205 is repeated for the next data electrode S.

After the process of step S105 shown in FIG. 10 is complete | finished, it transfers to step S106 of FIG. In step S106, based on the coordinate data (primary data) of the hole 101b acquired in step S105, that is, based on the position and number of the hole 101b, the CPU 112 performs a predetermined process on the data to obtain decoded data (hereinafter referred to as “decoded data”). Referred to as secondary data).
In step S107, it is determined whether or not predetermined data is included in the secondary data. In the present embodiment, the predetermined data is image data, audio data, and URL information. The image data includes still image data related to characters and graphics and moving image data. Audio data includes data related to audio and music. URL information is information that uniquely specifies the storage location of information resources such as files distributed on the network.
If the CPU 112 determines in step S107 that the secondary data does not include predetermined data, the CPU 112 proceeds to step S108 and outputs a warning sound from the speaker 110. Further, in the electronic device 102, light emitting means such as an LED may be provided at a position visible in the closed state in FIG. 1C, and the light emitting means may emit light to notify a warning. In addition to the alarm sound and the light emission of the light emitting means, a warning display may be displayed on the first display unit 105 or the second display unit 106. In this case, the user can recognize that the acquisition of information from the card 101 has failed due to an alarm sound or light emission of the light emitting means, and confirms the content of the warning by viewing the warning display with the electronic device 102 open. be able to. The case where the predetermined data is not included in the decoded data includes a case where an instruction to start information acquisition is input without placing the card 101 on the second display unit 106.

  If the CPU 112 determines in step S107 that the decoded data includes predetermined data, the CPU 112 proceeds to step S109 (see FIG. 9).

  In step S109, the CPU 112 determines whether the decoded data includes image data. When the CPU 112 determines that the decoded data includes image data, the CPU 112 proceeds to step S110, temporarily stores (buffers) the image data included in the decoded data in the memory 113, and then proceeds to step 111. Transition. On the other hand, if the CPU 112 determines that the image data is not included in the decoded data, the CPU 112 proceeds to step S111 without proceeding to step S110.

  In step S111, the CPU 112 determines whether or not audio data is included in the decoded data. If the CPU 112 determines that the decoded data includes audio data, the CPU 112 proceeds to step S112, temporarily stores the audio data included in the decoded data in the memory 113, and then proceeds to step S113. On the other hand, when determining that the decoded data does not include audio data, the CPU 112 proceeds to step S113 without proceeding to step S112.

In step S113, the CPU 112 determines whether or not URL information is included in the decrypted data. If the CPU 112 determines that the URL information is included in the decrypted data, the CPU 112 proceeds to step S114, temporarily stores the URL information included in the decrypted data in the memory 113, and then proceeds to step S115. On the other hand, when determining that the URL information is not included in the decrypted data, the CPU 112 proceeds to step S115 without proceeding to step S114.
In step S115, CPU 112 outputs a completion sound notifying that information acquisition is completed from speaker 110. In addition, instead of outputting a completion sound, the outer surface or side surface of the first housing 103 and the outer surface of the second housing 103 that are visible when the electronic device 102 is in the closed state as illustrated in FIG. Alternatively, a lamp such as an LED may be provided on the side surface and the lamp may be turned on.
In step S116, the CPU 112 determines whether or not the user has opened the electronic device 102 based on the signal from the open / close sensor 117 in accordance with the output of the completion sound. When the CPU 112 receives the detection signal from the open / close sensor 117, the CPU 112 determines that the electronic device 102 is in the closed state, and repeats the process of step S116. When the CPU 112 does not receive the detection signal from the open / close sensor 117, the CPU 112 determines that the electronic device 102 is in the open state, and executes the output process of step S117.

  In step S117, the CPU 112 executes a process of outputting the image data to the first display unit 105 when the image data is stored in the memory 113, and the audio data is stored in the memory 113. Then, a process of outputting audio data from the speaker 110 is executed. When the URL information is temporarily stored in the memory 113, the CPU 112 communicates with a predetermined location on the network specified by the URL information using the communication unit 116, and from the predetermined location, the image and / or Alternatively, audio data is acquired and stored in the memory 113, and image and / or audio data is read from the memory 113 and output to the first display unit 105 and / or the speaker 110.

  However, when two or more types of data are included among image data, audio data, and URL information, a process of outputting data is executed according to the output order stored in the data. When the process of step S117 ends, the process returns to step S101.

  Here, the process of outputting an image to the first display unit 105 is described, but an image may be output to the second display unit 106. In this case, after detecting the open state of the electronic device 102 in step S116, an image or sound instructing to remove the card 101 from the second display unit 106 is output, and the card 101 on the second display unit 106 is output. Is preferably removed. After that, it is detected that the card 101 has been removed, and then an image is output to the second display unit 106, or it is detected that the card 101 has been removed, and user input from the operation keys 8 is accepted. After that, it is preferable to output an image to the second display unit 106. In step S117, the image and sound may be output to an external device (not shown).

  In the process of step S117, when the decoded data includes two or more types of data among image data, audio data, and URL information, the data is output according to the output order stored in the data. Execute the process. When the process of step S117 ends, the process returns to step S101.

[Function and effect]
In the information acquisition system 100 according to the present embodiment, information can be stored in the card 101 using areas with different transmittances in the card 101. Specifically, the plate-like portion 101a of the card 101 is formed of a material with low transmittance (high reflectance), and a plurality of hole portions 101b as regions with high transmittance are formed in the plate-like portion 101a. Information can be stored in the card 101 based on the position and number of the plurality of hole portions 101b on the card 101.

  Moreover, in the information acquisition system 100 according to the present embodiment, the card 101 in which information is stored as described above can be acquired by a simple method. Information of the card 101 can be acquired by a simple method using the electronic device 102 including the first display unit 105 as the light emitting unit and the light sensing panel 107 as the light detecting unit. Information acquisition by the electronic device 102 is performed by placing the first display unit 105 on the opposite side of the card 101 with respect to the card 101 after placing the card 101 on the photosensitive panel 107. The light sensing panel 107 detects light output from the light. Then, based on the detection value detected by the light sensing panel 107, the coordinate data (the position and number of the hole 101b) of the hole 101b of the card 101 is acquired, and the decoded data is obtained based on the position and the number of the hole 101b. Generate. Then, the generated decoded data is output to the first display unit 105 and the speaker 110. Accordingly, the user selects the card information acquisition mode with the operation key 8, places the card 101 on the second display unit 106 of the electronic device 102, and then simply closes the electronic device 102 to remove the card 101. Information can be easily acquired. In addition, since the first display unit 105 (light emitting unit), the card 101, and the light sensing panel 107 (light detection unit) are formed so as to correspond to each other in shape and size, the first display unit 105 is caused to emit light. Can irradiate light to the area where the information on the card 101 is stored all at once, and the light sensing panel 107 stores the light sensor output of each cell by scanning the data electrode, and stores it in the card 101. The acquired information can be acquired at high speed.

  In addition, since the card 101 is formed in substantially the same size and shape as the second display unit 106 in which the card 101 is to be installed in the card information acquisition process, the user can use the card 101 in the card information acquisition process. 101 can be easily installed.

  In addition, since the light sensing panel 107 automatically detects the information stored in the card 101 after the card 101 is installed on the second display unit 106, it is ensured even when the information storage area of the card 101 is large. Information can be easily acquired from the card 101. That is, conventionally, when a user obtains a two-dimensional code or the like by irradiating infrared rays from a portable reading device or the like, reading may be difficult if the storage area of information is large. Therefore, even when the storage area of information is large, information can be acquired reliably and easily.

  In the present embodiment, the information is stored based on the position and number of the holes 101b. However, the information is stored by drawing the pattern of the currently used two-dimensional code using the holes 101b. It is also possible to do.

  Further, according to the information acquisition system 100 according to the present embodiment, when the predetermined information stored in the card 101 includes image data, the image data can be automatically output to the display unit. Information acquired from the card 101 can be easily viewed. The image data is data including data related to images such as characters and graphics.

  Further, according to the information acquisition system 100 according to the present embodiment, when the predetermined information stored in the card 101 includes audio data, the audio data can be automatically output from the audio output unit. Information acquired from the card 101 can be easily heard. The voice data includes data related to voice and music.

  In addition, according to the information acquisition system 100 according to the present embodiment, when the predetermined information stored in the card 101 includes URL information, the information (the URL stored in the URL) is accessed via the communication unit 116. For example, since a predetermined website can be automatically output to the display unit, the user can easily visually recognize the information acquired from the card 101. The URL information is information that uniquely specifies the storage location of information resources such as files distributed on the network.

  In the above description, the case where image data, audio data, and URL information itself are stored in the card 101 has been described. However, designation information that specifies image data, audio data, and URL information is stored in the card 101, and the electronic device A table in which designation information is associated with image data, audio data, and URL information may be stored in an internal or external storage unit 102. In this case, the electronic device 102 acquires the designation information from the card 101, extracts image data, audio data, or URL information corresponding to the designation information with reference to the table, and outputs them to the display unit or the audio output unit. According to such an information processing system, compared with the case where image data, audio data, and URL information itself are stored in the card 101, the storage amount in the card 101 with respect to the information amount output to the display unit or the audio output unit is reduced. Can be saved. Further, even if the designation information stored in the card 101 is not updated, information (image data, voice data) based on the designation information of the card 101 is updated by updating the image data, voice data, and URL information in the table of the storage unit. Data, URL information) can be kept up-to-date.

[Modification]
(A) In the above embodiment, the information acquired from the card 101 is temporarily stored and output to the first display unit 105 and the speaker 110. However, the information acquired from the card 101 is stored in the nonvolatile memory of the memory 113. Thus, the data stored in the memory 113 may be selected and output. That is, the data acquired from the card 101 and stored in the nonvolatile area of the memory 113 may be output to the display unit or the audio output unit based on a signal from the operation key 8 (input from the user). . In this way, it is not necessary to perform processing for acquiring information from the card 101 each time information stored in the card 101 is output to the display unit or the audio output unit. That is, once information is acquired from the card 101, the acquired information can be used repeatedly. In addition, information stored in the memory 113 can be exchanged with another electronic device via the communication unit 116.

(B) According to the information acquisition system 100 according to the present embodiment, when the game software is executed on the electronic device 102, the information read from the card 101 can be linked with the game software. For example, game characters and game execution conditions are stored in the card 101 based on the position and number of the holes 101b, and the game characters and game execution conditions read from the card 101 to the electronic device 102 are used in the game software. Then, the contents of the game software will change variously depending on the information on the card 101. In this case, at the start of the game, the game software can automatically select the card information acquisition mode and display a card installation instruction. In addition, the game can be automatically restarted after acquiring information from the card 101.

(C) Also, if the card 101 is used as a business card and unique information such as company information and name is stored in the card 101, an image of the business card can be displayed on the electronic device 102. For example, if password information is also stored in the card 101, a business card can be held in a state where the card 101 cannot be seen directly, and only the necessary partner can be notified of the password so that the information on the card 101 can be read. It is possible. In this case, it is only necessary to display the password information input instruction image together with the card installation instruction image in step S102 of FIG. 8 and accept the password input from the user.

(D) In the above embodiment, the first display unit 105 is used as a light emitting unit, and the card 101 is irradiated with light all at once. However, exposure scanning is performed line by line from one end of the card 101 to the other end. You may do it. For example, instead of the first display unit 105, a scanning unit 130 having a light emitting unit 130a shown in FIG. The scanning unit 130 performs exposure scanning one line at a time from one end of the card 101 to the other end. In this case, the CPU 112 scans the scanning electrode of the light sensing panel 107 in synchronization with the exposure scanning of the scanning unit 130.

(E) In the above embodiment, the information acquisition process is performed with the card 101 sandwiched between the electronic devices 102. However, the outside light (natural light) is used while the electronic device 102 is in the open state of FIG. Then, the transmitted light of the card 101 may be detected.

(F) The information acquisition method according to the present embodiment is applicable to the electronic device 102 shown in FIG. The electronic device 102 in FIG. 22A includes a first display unit 105, a light sensing panel 107, and a second display unit 106 on one side of a housing 118. The electronic device 102 is not configured to be opened and closed like the electronic device 102 of FIG.

The information acquisition method according to the present embodiment can also be applied to the electronic apparatus 102 shown in FIG. That is, the card 101 is installed on the light sensing panel 107, information is acquired from the card 101 using external light, and image data and audio data are output to an internal or external display unit and audio output unit. Can do. Note that the second display unit 106 may be omitted when information is not output to the second display unit 106.
Further, the information acquisition method according to the present embodiment can be applied to the electronic device 102 shown in FIG. The electronic device 102 in FIG. 22B includes a light sensing panel 107 and a second display unit 106 on one side of a housing 118. The electronic device 102 includes only one display unit, that is, only the second display unit 106. The information acquisition method according to the present embodiment can also be applied to the electronic apparatus 102 shown in FIG. That is, the card 101 is installed on the light sensing panel 107, information is acquired from the card 101 using external light, and image data and audio data are output to an internal or external display unit and audio output unit. Can do.

(G) In the above embodiment, the information encoded based on the position and number of the holes 101b is stored in the card 101. However, the information encoded based on any one of the position or number of the holes 101b is stored. You may memorize | store in the card | curd 101. FIG. In this case, in step S8 of FIG. 8, decoded data is created using only one of the position and the number of the holes 101b.

(2) Second Embodiment In the present embodiment, the hole 101b having a different size is formed in the card 101, and information is encoded based on the size of the hole 101b in addition to the position and number of the holes 101b. Is stored in the card 101.

[overall structure]
Since the overall configuration of the second embodiment is the same as the overall configuration of the first embodiment described above (see FIG. 1), description thereof is omitted here.

[Card configuration]
FIG. 11 is a perspective view (a) and a sectional view (b) of a card according to the second embodiment.

  The card 101 includes a plate-like portion 101a and a plurality of hole portions 101b formed in the plate-like portion 101a. The plate-like portion 101 is formed by resin formation or the like and is made of a material that hardly transmits light. The hole portion 101b has a substantially circular shape in plan view, and is formed so as to penetrate from the first surface 101c to the second surface 101d of the plate-like portion 101a.

  In the present embodiment, the size of the hole 101b is formed in two sizes, “large” and “small”. Here, the size of the hole 101b is defined by the area. The size of the “small” hole 101b is the area Sa1, and the size of the “large” hole 101b is the area Sa2 (> Sa1). The plate-like portion 101a is divided into a predetermined number of areas 101e, and each hole portion 101b is formed for each area 101e. Note that the hole 101b is not necessarily formed in each area 101e. In the present embodiment, as shown in FIG. 12D, the area 101e of the card 101 is configured to correspond to a set of cells P of 5 rows and 5 columns of the photosensitive panel 107.

  In this card 101, predetermined information is stored according to the size (area) of the hole 101b in addition to the position and number of the holes 101b, and the second surface 101d is arranged to face the light sensing panel 107. Then, the light sensing panel 107 detects the light transmitted through the card 101, thereby detecting the number, position, and area (size) of the hole 101 b, and outputting them to the CPU 112.

[Information acquisition method]
The flowchart related to the information acquisition method according to the present embodiment is substantially the same as the flowchart related to the information acquisition method according to the first embodiment (see FIGS. 8 to 10). Differences will be described with reference to FIGS. 8 to 10, 12, and 13.

  FIG. 12A is a diagram showing the arrangement of cells in the photosensitive panel 107 according to this embodiment, and FIG. 12B is a diagram showing the coordinates of the cells P on the photosensitive panel 107. FIG. (C) is a diagram showing the coordinate data of each cell P of the light sensing panel 107. Here, Pxy (x = 1,... M, y = 1,... N) represents the coordinates of cells in x rows and y columns. Therefore, for example, the detection value corresponding to 2 rows and 2 columns shown in FIG. 8C represents the detection value of the cell P22.

  FIG. 12D is a diagram showing the arrangement of the area D corresponding to the area 105e in the light sensing panel 107, and FIG. 12E is a diagram showing the coordinates of the area D, and FIG. Is coordinate data of area D (area data of hole 101b).

  In FIG. 12D, the cell P of the light-sensitive panel 107 is indicated by a solid line, and the area D is indicated by a broken line.

  FIG. 13 is a flowchart showing the processing content of step S106 in the flowchart (see FIGS. 8 to 10) regarding the information acquisition method according to the present embodiment.

  In FIG. 8, the card information acquisition mode is set (S101), and it is detected that the card 101 is installed on the light sensing panel 107 and the electronic device 102 is closed according to the card installation instruction display (S102) (S103). When the first display unit 105 emits light (S104), the detection value is acquired from the light sensing panel 107 and the coordinate data of the hole 101b is generated in step S105.

  For example, as illustrated in FIG. 12A, when light is detected in a black portion of the cells of the light sensing panel 107, the coordinates of the light sensing panel 107 illustrated in FIG. , P22, P23, P24, P32, P33, P34, P42, P43, and P44 are assigned a value of “1” as shown in FIG. “0” is assigned to the coordinates where no light is detected. The CPU 112 stores data related to the light detection value in a predetermined area of the memory 113. When acquisition of detection values and creation of coordinate data are completed for all cells of the light-sensitive panel 107, the process proceeds to step S106 shown in FIG. Then, in step S106, based on the coordinate data (primary data) (position and coordinates of the hole 101b) regarding the position of the hole 101b of the card 101 acquired from the light sensing panel 107, and the area of the hole 101b, the CPU 112. Performs predetermined processing on the data to form decoded data (hereinafter referred to as secondary data).

  Here, the processing content of step S106 is demonstrated. As described above, in the present embodiment, the hole portion 101b formed in the card 101 is disposed in the area 101e divided into a predetermined number in the plate-like portion 101a. In the present embodiment, as shown in FIG. 12D, the area 101e corresponds to the area surrounded by the 5 rows by 5 columns of cells P of the light sensing panel 107, and this area is designated as area D ( D11... Dmn).

  In step S301 illustrated in FIG. 13, the CPU 112 determines whether or not there is a cell P to which “1” is assigned to the area D sequentially from the area D11. If the CPU 112 determines that the cell P of “1” exists in the area D, the CPU 112 executes step S303. For example, referring to FIGS. 12C, 12D, and 12E, there are nine “1” cells in the area D11.

  In step S303, it is determined whether or not the number of “1” cells P existing in the area D is within a predetermined number. If it is determined that the number of “1” cells P is within the predetermined number, the process proceeds to step S 304, where “1” is assigned to the area D as area data and stored in the memory 113. For example, “1” is assigned to D21 in FIG.

  On the other hand, when the CPU 112 determines in step S303 that the number of “1” cells P existing in the area D exceeds the predetermined number, the process proceeds to step S305, and the area data “2” is stored in the area D. Store in the allocation memory 113. For example, “2” is assigned to D11 in FIG.

  When the CPU 112 determines in step S301 that the cell P of “1” does not exist in the area D, the process proceeds to step S302 and the area data “0” is assigned to the area D and stored in the memory 113. . For example, “0” is assigned to D22 in FIG.

  In the present embodiment, the predetermined number in step S303 is four. That is, if there are 4 or less “1” cells P in the area D, “1” is assigned to the area D, and there are 5 or more “1” cells P in the area D. Assigns “2” to the area D. In other words, a hole 101b having a size of “small” is formed in the area D to which the value of “1” is assigned, and the size of the area D to which the value of “2” is assigned. A “large” hole 101b is formed. For example, in D11 illustrated in FIG. 12D, since there are nine “1” cells P, “2” is allocated to the area D11. If there is no “1” cell P in area D, “0” is assigned to area D11. It means that the hole 101b is not formed in the area D to which “0” is assigned.

  In step 306, the CPU 112 determines whether or not the allocation of area data (“0”, “1”, “2”) has been completed for all areas D (D11 to Dmn). When the allocation of the area data (“0”, “1”, “2”) is completed for all areas D (D11 to Dmn), the process proceeds to step S307. On the other hand, if data allocation has not been completed for all areas D (D11 to Dmn), the process returns to step S301, and data allocation is performed for the next area D.

  In step S307, a database relating to the area data assigned to all areas D is created, and the process proceeds to step S308.

  In step S308, the CPU 112 performs predetermined processing based on the coordinate data (number and position of the holes 101b) of the hole 101b formed in step S105 and a database relating to the area data of the hole 101b. Decrypted data is created, and the process proceeds to step S107.

[Function and effect]
According to the information acquisition system 100 according to the present embodiment, the same operational effects as in the first embodiment can be obtained.
Furthermore, according to the present embodiment, in addition to the coordinate data (the position and number of the hole 101b) of the hole 101b formed in the card 101, various information is stored in the card 101 according to the size of the hole 101b. Is possible. That is, in addition to the position and number of the holes 101b, the information is stored according to the size of the holes 101b, so that the information storage density can be increased as compared with the first embodiment. In the above description, the case where the size of the hole 101b is two types of “large” and “small” has been described, but the size of the hole 101b may be three or more types. As the kind of size of the hole 101b is increased, the information storage density can be further increased.

[Modification]
In the above, information encoded based on the position, number and size of the hole 101b is stored in the card 101. However, information encoded based only on the size of the hole 101b may be stored in the card 101. good. In this case, in step S308 of FIG. 13, decoded data is created based only on the hole area database created in step S307.

(3) Third Embodiment In the information acquisition system 100 according to the first and second embodiments, information is stored in the card 101 using regions having different light transmittances, and the difference in light transmittance is utilized. The information is obtained from the card 101. In the present embodiment, information is stored using areas having different light reflectivities in the card 101, and information is acquired from the card 101 using differences in light reflectivity.

  Here, the same components as those in FIG. 1 according to the first embodiment are denoted by the same reference numerals, and description thereof is omitted. The information acquisition system 100 according to the present embodiment includes a scanning unit 120 instead of the light sensing panel 107 according to the first embodiment.

[Scanning unit]
FIG. 16 is a perspective view of the scanning unit 120.

  The scanning unit 120 is disposed in the second housing 104 as shown in FIG. 14 and is covered with a film 119 that transmits light well. A card 101 is placed on the film 119 when card information is acquired. The scanning unit 120 includes a light emitting means 120a composed of a halogen lamp, an LED, etc., and a rod array lens 120b for condensing the reflected light from the card 101 exposed and scanned by the light emitting means 120a and inputting it to the optical sensor. And a line sensor 120c for detecting light input from the rod array lens 120b. The scanning unit 120 exposes and scans the card 101 line by line while the card 101 is placed on the film 119, detects reflected light from the card 101, and outputs the detected value to the CPU 112.

  In the present embodiment, since the second display unit 106 is disposed below the scanning unit 120, the scanning unit 120 is retracted to a position that does not hinder the visual recognition of the second display unit 106 except when acquiring card information. Control as you do.

[Card configuration]
The configuration of the card 101 according to the third embodiment is also the same as the configuration of the card 101 according to the first embodiment shown in FIG. However, in the present embodiment, the plate-like portion 101a is formed so that the reflectance of the second surface 101d of the card 101 disposed to face the light sensing panel 107 is sufficiently large. More specifically, the reflectance of the second surface 101d of the plate-like portion 101a is sufficiently large so that the detection value of the reflected light at the second surface 101d can be distinguished from the detection value of the reflected light at the hole portion 101b. .

[Principle of information acquisition using light reflected from card]
FIG. 17 is an explanatory diagram for explaining an information acquisition principle using reflected light from a card.

  When the card information is acquired, the card 101 is placed on the film 119 as shown in FIG. At this time, the second surface 101d of the card 101 is placed on the film 119, as in the first embodiment. When the scanning unit 120 is driven and exposure scanning on the card 101 is started, as shown in FIG. 17, the light from the light emitting means 120a of the scanning unit 120 in the plate-like portion 101a (the region other than the hole portion 101b). (Arrow a) is reflected by the plate-shaped portion 101 a having a high reflectance, most of the incident light becomes reflected light (arrow b), and strong reflected light is detected by the line sensor 120 c of the scanning unit 120. On the other hand, in the hole 101b, light (arrow c) from the light emitting means 120a of the scanning unit 120 is almost transmitted through the hole 101b, and weak reflected light is detected by the line sensor 120c of the scanning unit 120. Information is stored in the card 101 and information is acquired from the card 101 using the difference between the reflectance of the plate-like portion 101 a and the reflectance of the hole portion 101 b.

[Information acquisition method]
FIG. 18 is a flowchart regarding the information acquisition method according to the present embodiment.

  The following processing is performed by the CPU 112 executing an information acquisition program stored in the memory 113 of the electronic device 102. The information acquisition program may be stored in the recording medium 114a or acquired from the network by the communication unit 116.

  In step S401, the CPU 112 determines whether or not switching from the operation key 108 to the card information acquisition mode has been accepted. If the CPU 112 accepts switching to the card information acquisition mode, the CPU 112 proceeds to step S402. CPU112 repeats the process of step S401, when switching to card information acquisition mode is not received.

  In step S <b> 402, the CPU 112 displays an instruction image for instructing installation of the card 101 on the film 119 on the second display unit 106. This instruction image is, for example, “Place card here”. The instruction image may be output to the first display unit 105. The instruction image in this case is, for example, “Place the card on the lower screen”.

  In step S403, the CPU 112 determines whether or not there is an instruction to start information acquisition from the operation key 108 or the like. If the CPU 112 determines that there is a start instruction, the CPU 112 proceeds to step S404. That is, if a start instruction is input from the operation key 108 after the card 101 is placed on the film 119 in accordance with the instruction image in step S402, the process proceeds to step S404.

  In step S404, the CPU 112 drives the scanning unit 120 to detect the coordinate data (position and number) of the hole 101b from the card 101.

  FIG. 20 is a flowchart showing the process of step S404. In step S501, the CPU 112 drives the scanning unit 120 to acquire a detection value for one line. Here, it is assumed that one line is equal to one column of cells P of the photosensitive panel 107 in the first embodiment shown in FIGS. Therefore, in the following description, it is assumed that the coordinate interval acquired by the CPU 112 from the scanning unit 120, that is, the resolution of the scanning unit 120 is equal to the cell P shown in FIGS.

  In step S502, the CPU 112 sequentially compares the detected value of the coordinates for one line acquired in step S501 with a predetermined threshold value. When the CPU 112 determines that the detected value is equal to or greater than the threshold value, the CPU 112 assigns “0” (indicating that the hole 101b is not formed) to the coordinate, and the coordinate and “0” as shown in FIG. 5C. Are stored in the memory 113 (step S503). On the other hand, when the CPU 112 determines that the detected value is less than the threshold value, the CPU 112 assigns “1” (indicating that the hole 101b is formed) to the coordinates, and associates the coordinates with “1” in the memory 113. Store (step S504).

  In step S505, the CPU 112 determines whether or not the entire area of the card 101 has been scanned. When determining that the entire area of the card 101 has been scanned, the CPU 112 ends the process of step S404, and proceeds to step S405 illustrated in FIG. On the other hand, when the CPU 112 determines that the entire area of the card 101 has not been scanned yet, the CPU 112 returns to step S501 and causes the scanning unit 120 to scan the next one line.

  The coordinate data of the hole 101b of the card 101 as shown in FIG. 5C is acquired by the processing of steps S501 to S505 described above. In FIG. 5C, the coordinate P of “1” is “coordinate where the hole 101b is formed”, and the coordinate P of “0” is “coordinate where the hole 101b is not formed”.

In step S405, the CPU 112 performs predetermined processing on the coordinate data (primary data) of the hole 101b acquired in step S404, and generates decoded data (secondary data). Specifically, the decoded data is created based on the position and number of the holes 101b obtained from the coordinate data.
In step S406, it is determined whether or not predetermined data is included in the decoded data.
In the present embodiment, the predetermined data is image data, audio data, and URL information. The image data includes still image data related to characters and graphics and moving image data. Audio data includes data related to audio and music. URL information is information that uniquely specifies the storage location of information resources such as files distributed on the network.

  If the CPU 112 determines in step S406 that the predetermined data is not included in the decoded data, the process proceeds to step S407. In step S <b> 407, the CPU 112 outputs a warning display on the first display unit 105. A warning sound may be generated from the speaker 110 instead of the warning display output or together with the warning sound display. The user can know that the information acquisition from the card 101 has failed by the warning display or the warning sound by this processing. The case where the predetermined data is not included in the decoded data includes a case where an instruction to start information acquisition is input in a state where the card 101 is not placed on the film 119. And CPU112 returns to step S401 after performing the process of step S407.

  On the other hand, when the CPU 112 determines in step S406 that the decoded data includes predetermined data, the process proceeds to step S408.

  In step S408 illustrated in FIG. 19, the CPU 112 determines whether image data is included in the decoded data. If the CPU 112 determines that the decoded data includes image data, the CPU 112 proceeds to step S409. In step S409, the CPU 112 temporarily stores the image data included in the decoded data in the memory 113, and then proceeds to step S410. On the other hand, if the CPU 112 determines that the image data is not included in the decoded data, the CPU 112 proceeds to step S410 without proceeding to step S409.

  In step S410, CPU 112 determines whether or not audio data is included in the decoded data. When the CPU 112 determines that the decoded data includes audio data, the CPU 112 proceeds to step S411. In step S411, the CPU 112 temporarily stores the audio data included in the decoded data in the memory 113, and then proceeds to step S412. On the other hand, when determining that the decoded data does not include audio data, the CPU 112 proceeds to step S412 without proceeding to step S411.

  In step S412, the CPU 112 determines whether or not URL information is included in the decrypted data. If the CPU 112 determines that the URL information is included in the decrypted data, the CPU 112 proceeds to step S413. In step S413, the CPU 112 temporarily stores the URL information included in the decrypted data in the memory 113, and proceeds to step S414. On the other hand, when determining that the URL information is not included in the decrypted data, the CPU 112 proceeds to step S414 without proceeding to step S413.

  In step S <b> 414, the CPU 112 executes a process of outputting the image data to the first display unit 105 when the image data is stored in the memory 113. Further, the CPU 112 executes a process of outputting the audio data from the speaker 110 when the audio data is stored in the memory 113. When the URL information is temporarily stored in the memory 113, the CPU 112 communicates with a predetermined location on the network specified by the URL information using the communication unit 116, and from the predetermined location, the image and / or Alternatively, audio data is acquired and stored in the memory 113, and image and / or audio data is read from the memory 113 and output to the first display unit 105 and / or the speaker 110.

  Here, the process of outputting an image to the first display unit 105 is described, but an image may be output to the second display unit 106. In this case, since the card 101 is installed above the second display unit 106 during the information acquisition process, a completion sound or completion display is made after each data buffer, and the card 101 is removed from the film 119 to the user. It is preferable to indicate that. Thereafter, it is preferable to detect that the card 101 has been removed or to output an image to the second display unit 106 based on an input from the operation key 8. In step S414, the image and sound may be output to an external device (not shown).

  In the process of step S414, if the decoded data includes two or more types of data among image data, audio data, and URL information, the data is output in accordance with the output order stored in the data. Execute the process. When the process of step S414 ends, the process returns to step S401.

[Function and effect]
In the information acquisition system 100 according to the present embodiment, information can be stored in the card 101 using areas having different reflectivities in the card 101. Specifically, the plate-like portion 101a of the card 101 is formed of a material having a high reflectance, and a plurality of holes 101b having a low reflectance are formed in the plate-like portion 101a. Information encoded based on the position and number of the plurality of hole portions 101b in the card 101 can be stored in the card 101.

  Further, in the information acquisition system 100 according to the present embodiment, information stored in the card 101 can be acquired easily and reliably. Specifically, by placing the card 101 on the film 119 and exposing and scanning the card 101 by the scanning unit 120, the coordinate data of the hole 101b of the card 101 is obtained, and the hole 101b obtained from the coordinate data is acquired. Based on the position and number, the information stored in the card 101 is decrypted. The decoded data is automatically output to the display unit and the audio output unit. Therefore, the user can simply and reliably acquire information from the card 101 simply by placing the card 101 on the film 119 and giving a start instruction.

  Further, since the card 101 is formed in substantially the same size and shape as the film 119 on which the card 101 is to be placed during the card information acquisition process, the user can easily hold the card 101 during the card information acquisition process. Can be installed.

  Since the scanning unit 120 automatically detects information stored in the card 101 after the card 101 is placed on the film 119, the card 101 can be surely and easily used even when the information storage area of the card 101 is large. Information can be acquired from 101. That is, conventionally, when a user obtains a two-dimensional code or the like by irradiating infrared rays from a portable reading device or the like, reading may be difficult if the storage area of information is large. Therefore, even when the storage area of information is large, information can be acquired reliably and easily.

  In the present embodiment, the information is stored based on the position and number of the holes 101b. However, the information is stored by drawing the pattern of the currently used two-dimensional code using the holes 101b. It is also possible to do.

  Further, according to the information acquisition system 100 according to the present embodiment, when the predetermined information stored in the card 101 includes image data, the image data can be automatically output to the display unit. Information acquired from the card 101 can be easily viewed. The image data is data including data related to images such as characters and graphics.

  Further, according to the information acquisition system 100 according to the present embodiment, when the predetermined information stored in the card 101 includes audio data, the audio data can be automatically output from the audio output unit. Information acquired from the card 101 can be easily heard. The voice data includes data related to voice and music.

  In addition, according to the information acquisition system 100 according to the present embodiment, when the predetermined information stored in the card 101 includes URL information, the information (the URL stored in the URL) is accessed via the communication unit 116. For example, since a predetermined website can be automatically output to the display unit, the user can easily visually recognize the information acquired from the card 101. The URL information is information that uniquely specifies the storage location of information resources such as files distributed on the network.

  In the information acquisition system 100 according to the present embodiment, information can be acquired from the card 101 while the electronic device 102 is kept open. Therefore, the operation of closing the electronic device 102 by placing the card 101 on the film 119 and the operation of opening the electronic device 102 after information acquisition are omitted.

[Modification]
(A) In the above embodiment, the information acquired from the card 101 is temporarily stored and output to the first display unit 105 and the speaker 110. However, the information acquired from the card 101 is stored in the nonvolatile memory of the memory 113. Thus, the data stored in the memory 113 may be selected and output. That is, the data acquired from the card 101 and stored in the nonvolatile area of the memory 113 may be output to the display unit or the audio output unit based on a signal from the operation key 8 (input from the user). . In this way, it is not necessary to perform processing for acquiring information from the card 101 each time information stored in the card 101 is output to the display unit or the audio output unit. That is, once information is acquired from the card 101, the acquired information can be used repeatedly. In addition, information stored in the memory 113 can be exchanged with another electronic device via the communication unit 116.

(B) According to the information acquisition system 100 according to the present embodiment, when the game software is executed on the electronic device 102, the information read from the card 101 can be linked with the game software. For example, game characters and game execution conditions are stored in the card 101 based on the position and number of the holes 101b, and the game characters and game execution conditions read from the card 101 to the electronic device 102 are used in the game software. Then, the contents of the game software will change variously depending on the information on the card 101. In this case, at the start of the game, the game software can automatically select the card information acquisition mode and display a card installation instruction. In addition, the game can be automatically restarted after acquiring information from the card 101.

(C) Also, if the card 101 is used as a business card and unique information such as company information and name is stored in the card 101, an image of the business card can be displayed on the electronic device 102. For example, if password information is also stored in the card 101, a business card can be held in a state where the card 101 cannot be seen directly, and only the necessary partner can be notified of the password so that the information on the card 101 can be read. It is possible. In this case, in step S402 shown in FIG. 18, an image of a password information input instruction may be displayed together with an image of a card installation instruction, and the password input from the user may be accepted.

(D) Alternatively, after the card 101 is placed on the film 119, the information acquisition process may be performed after the electronic device is closed. In this case, as shown in FIG. 21, the light transmitted through the hole 101 b from the scanning unit 120 is reflected by the first display unit 105, and the reflected light returns to the scanning unit 120. Therefore, the scanning unit 120 can detect the difference between the intensity of the reflected light from the first display unit 105 and the intensity of the reflected light from the plate-like part 101a. That is, in consideration of the optical path difference between the reflected light at the first display unit 105 and the reflected light at the plate-like portion 101a, the reflectance at the first display portion 105 and the reflectance at the plate-like portion 101a are Set appropriately. In this case, since the card 101 is sandwiched between the electronic devices 102 and information acquisition processing is performed, the intensity of reflected light on the card 101 is increased even when the intensity of external light incident from the hole 101b of the card 101 is high. It can be detected reliably.
Instead of sandwiching the card 101 between the electronic devices 102, a plate-like portion 101a having a low reflectivity may be provided on the first surface 101c of the card 101 so that external light does not enter the hole portion 101b.

(E) In addition, the information acquisition method according to the present embodiment is applicable to the electronic device 102 illustrated in FIG. 22A includes a first display unit 105, a film 119, a scanning unit 120, and a second display unit 106 on one surface of a housing 118. The electronic device 102 is not configured to be opened and closed like the electronic device 102 of FIG. The information acquisition method according to the present embodiment can also be applied to the electronic apparatus 102 shown in FIG. That is, the card 101 can be placed on the film 119, information can be acquired from the card 101, and image data and audio data can be output to an internal or external display unit and audio output unit as described above. Note that the second display unit 106 may be omitted when information is not output to the second display unit 106.

  Further, the information acquisition method according to the present embodiment can be applied to the electronic device 102 shown in FIG. The electronic device 102 in FIG. 22B includes a film 119, a scanning unit 120, and a second display unit 106 on one side of a housing 118. The electronic device 102 includes only one display unit, that is, only the second display unit 106. The information acquisition method according to the present embodiment can also be applied to the electronic apparatus 102 shown in FIG. That is, the card 101 can be placed on the film 119, information can be acquired from the card 101, and image data and audio data can be output to an internal or external display unit and audio output unit as described above.

(F) Further, instead of the scanning unit 120 and the second display unit 106 in this embodiment, an LCD with an image sensor may be used.

(G) In addition, the card 101 in which the hole portions 101b having different sizes according to the second embodiment are formed is used as a method for storing and acquiring information using areas having different reflectivities in the card 101 according to the third embodiment. Can be applied. In this case, the overall configuration of the information acquisition system 101 is the same as that of the third embodiment, and the card 101 according to this embodiment is the same as that of the second embodiment.

  The information acquisition process in this case is the same as that shown in FIGS. However, since the card 101 having the hole 101b having a different size is used here, the processing in step S405 illustrated in FIG. 18 is different from that in the third embodiment. That is, in step S405 according to the present embodiment, the flowchart of FIG. 13 according to the second embodiment is used. Thus, information stored in the card 101 can be decoded based on the area (size) of the hole 101b in addition to the position and number of the hole 101b.

(4) Fourth Embodiment In this embodiment, a color filter 101f or 101g is provided in the hole 101b of the card 101, information is stored in the card 101 using the color of light transmitted through the hole 101b, and from the card 101. Get information. The color filters 101f and 101g are made of cellophane, for example. In the present embodiment, information is stored in the card 101 and information is acquired from the card 101 based on the color in addition to the position and number of the holes 101 b of the card 101. In this embodiment, in addition to the position, number, and size of the hole 101b of the card 101, information encoded based on the color is stored in the card 101, and the position, number of the hole 101b of the card 101 is stored. The information stored in the card 101 is decoded based on the color in addition to the size.

FIG. 23 is a cross-sectional view of the card 101 according to the fourth embodiment.
In the card 101 of FIG. 23A, a color filter 101f is provided on one surface of the plate-like portion 101a. The color filter 101f has a predetermined number of color portions. The color filter 101f is formed in any one of the predetermined number of colors for each portion corresponding to the hole 101b. Accordingly, the light incident on the hole 101b of the card 101 is output as one of the predetermined number of colors. As a result, it is possible to store information in the card 101 and acquire information stored in the card 101 using the color in addition to the position and number of the hole 101b of the card 101. Further, in addition to the position, number, and size of the hole 101b of the card 101, the information encoded based on the color is stored in the card 101 and added to the position, number, and size of the hole 101b of the card 101. Thus, the information stored in the card 101 can be decoded and acquired based on the color.

In the card 101 of FIG. 23B, a color film 101g is embedded in the hole 101b. The color film 101g is formed in any one of a predetermined number of colors. Accordingly, the light incident on the hole 101b of the card 101 is output as one of the predetermined number of colors. Thereby, information is stored in the card 101 based on the color in addition to the position and number of the hole 101b of the card 101, and the information stored in the card 101 is also stored in the position and number of the hole 101b of the card 101. In addition, it is possible to perform decoding based on the color. Further, in addition to the position, number, and size of the hole 101b of the card 101, information encoded based on the color is stored in the card 101, and the information stored in the card 101 is stored in the hole of the card 101. It is possible to perform decoding based on the color in addition to the position, number, and size of 101b.

[Information acquisition method]
FIG. 24 is an explanatory diagram for explaining the principle of detecting the color of the hole 101b in the present embodiment.

FIG. 24 shows a configuration in which a color filter 107a is arranged on the light sensing panel 107 according to the first embodiment. In this configuration, the card 101 is installed on the light sensing panel 107 via the color filter 107a. Further, the first display unit 105 is disposed on the opposite side of the light sensing panel 107 with respect to the card 101 when acquiring card information. As shown in FIG. 25, the color filter 107a is arranged so that R (red), G (green), and B (blue) correspond to each cell P of the light sensing panel 107. The correspondence relationship between each cell P of the light sensing panel 107 and RGB is stored in the memory 113 in advance. A set of adjacent RGB cells is a pixel PP. The color of the incident light to the light sensing panel 107 is determined for each pixel PP. A predetermined number of colors of the hole portion 101b are determined in advance. Each color of the predetermined number of colors is determined by a ratio of detection values of RGB cells in the pixel PP. Each color and the ratio of RGB detection values are associated with each other and stored in the memory 113 as a color table.

  Referring to FIG. 24, the light incident on the hole 101b from the first display unit 105 passes through the color filter 101f (yellow) that determines the color of the hole 101b, and is separated into RGB colors by the color filter 107 for RGB separation. Then, it enters the light sensing panel 107. The CPU 112 acquires the detection value of each cell from the light sensing panel 107, calculates the ratio of the detection value of each RGB cell for each pixel PP, and corresponds to the detection value ratio from the color table stored in the memory 113. Determine the color to be used. Then, a color database is created by associating the coordinates of the pixel PP with the color of the detection light.

  If such a color database is applied to S106 of FIG. 8 according to the first embodiment, information encoded based on the color of the hole 101b in addition to the position and number of the hole 101b is stored in the card 101. At the same time, the information stored in the card 101 is decoded based on the color of the hole 101b in addition to the position and number of the hole 101b of the card 101.

If the color database is applied to step S308 in FIG. 13 according to the second embodiment, the color of the hole 101b is added to the position and number of the hole 101b and the area data (size of the hole 101b). The information encoded based on the information is stored in the card 101, and the information stored in the card 101 is added to the position and number of the hole 101b and area data (size of the hole 101b), and the color of the hole 101b. Can be decrypted based on
Instead of using the light sensing panel 107, the color of the hole 101b may be detected using the scanning unit 120 according to the third embodiment. In this case, a full color sensor is used for the line sensor 120c of the scanning unit 120.

[Modification]
In the above, information encoded based on the position, number, and color of the hole 101b is stored in the card 101, or information encoded based on the position, number, size, and color of the hole 101b is stored in the card 101. Although stored, information encoded based only on the color of the hole 101b may be stored in the card 101.

(5) Fifth Embodiment In the first to fourth embodiments, information encoded based on at least one of the position, number, size, and color of the hole 101b is stored in the card 101, and The information stored in the card 101 is decoded based on at least one of the position, number, size, and color of the hole 101b, but the array of the holes 101b on the card 101 constitutes an image. As described above, the hole 101b may be formed in the card 101.
FIG. 26 shows an example of a card in which the hole arrangement itself constitutes an image. As shown in FIG. 26 (b), an airplane image as shown in FIG. 26 (a) is constituted by the holes 101b arranged on the card 101. Note that the hole 101b may be disposed so as to fill the entire image shown in FIG. 26A, or the hole 101b may be disposed along the contour.

  When the card 101 of this embodiment is applied to any of the first to third embodiments, the coordinate data (FIG. 5C or FIG. 12C) of the hole 101b is acquired, and the coordinate data itself is 2 A value image can be output to the display unit. In this case, it is possible to produce a state in which images are sequentially output from the acquired portion of the hole 101b of the card 101 by sequentially outputting the coordinate data from the coordinates for which the acquisition of the coordinate data has been completed.
