Description

  The present invention relates to a technique for improving work efficiency and preventing inspection mistakes when an operator confirms the correctness of a plurality of parts included in a predetermined apparatus.

  For example, in automobiles, each part (eg, tires, mirrors, bumpers, wheels, seats, car navigation, etc.) is often different depending on the purchaser's preference even if they are the same car type. It is necessary to check whether the finished product is as it was ordered. Conventionally, an operator checks each part based on a check sheet on which a model number of a part that should be attached to the product is printed, and enters the check result on the check sheet.

  In such a conventional method, an operator performs work while holding a writing instrument such as a ballpoint pen and a check sheet, and when using both hands (for example, opening a bonnet or a door, removing a clasp). In some cases, the writing instrument and the check sheet must be released from the hand, resulting in poor work efficiency. Further, for example, when an operator tries to improve work efficiency and enters check results of a plurality of parts at once, an entry error or an inspection error occurs. Furthermore, for example, when changing the writing instrument, the writing instrument may be dropped and the product may be damaged.

  For example, Japanese Patent Application Laid-Open No. 7-318565 discloses an analyzer with a voice input / output function that enables the analyzer to be operated by voice even when both hands are closed. Specifically, an analyzer that accepts an instruction to start or stop measurement from the outside and outputs the measurement result to the outside has a function to accept an instruction from the outside by voice and a function to output to the outside by voice. However, according to the technology described in the publication, for example, when working in a certain place such as a desk, the analyzer installed on the desk may be operated by voice. When working while looking around, it is necessary to return to the analyzer each time, and it cannot be said that the work efficiency is improved.

  For example, Japanese Patent Application Laid-Open No. 63-4700 discloses a printed wiring board appearance inspection device that can transmit part data to an inspector by hearing and reduce visual fatigue due to inspection. Specifically, the printed wiring board appearance inspection apparatus includes an X / Y coordinate reading apparatus that reads coordinates on a slave printed wiring board to be inspected, and component data for the X / Y coordinates of a standard main printed wiring board. A voice data storage circuit for recording the voice data read out from the voice data storage circuit, a voice synthesis circuit for synthesizing the voice data read out from the voice data storage circuit, a voice output device for outputting the voice synthesized by the voice synthesis circuit, and And a central processing unit for controlling. However, in this publication, voice input is not performed and the above problems cannot be solved.

  Furthermore, for example, Japanese Unexamined Patent Application Publication No. 2007-18870 discloses an appearance inspection guidance system that can maintain stable quality by improving work efficiency in the appearance inspection process. Specifically, it is an appearance inspection guidance system that performs an appearance inspection of an assembled wire harness based on a work instruction that is read and displayed by a predetermined instruction, and is an image display means that displays an image of at least an inspection portion. Or a voice means for transmitting the inspection portion by voice, and a shipping label is issued only to the wire harness that has undergone the appearance inspection. However, even in this publication, voice input is not performed and the above problems cannot be solved.

Further, for example, Japanese Patent Application Laid-Open No. 2003-194733 discloses an appearance inspection support system that can easily perform a correction input operation of inspection result data even when both hands of an operator are occupied, and can improve work efficiency. It is disclosed. Specifically, the appearance of the object to be inspected is photographed with an imaging device, image processing is performed, and appearance inspection means for inspecting the quality of the object to be inspected, and inspection result data of the appearance inspection means are written and Data input / output means for reading out the written data, display means for reading out and displaying the inspection result data written in the data input / output means, and correction input of the inspection result data displayed on the display means An information processing means including a data correction input means for performing and a data correction processing means for correcting the inspection result data based on the correction input of the data correction input means, and displayed on the display means Based on the inspection result data, an operator visually reinspects the inspection target object, and when the inspection result data has an error, the operator uses the data correction input means to In the appearance inspection support system for the inspection object, which corrects the inspection result data and writes the corrected inspection result data to the data input / output unit, the data correction input unit recognizes the voice uttered by the operator. Voice recognition means for outputting recognition data corresponding to the voice to the data correction processing means. However, according to the technique described in the publication, when working in a certain place such as a desk, the inspection result data displayed on the display device of a PC (personal computer) installed on the desk is viewed. However, it may be possible to correct the inspection result data by voice, but when working while looking around each part of a product, it is necessary to return to the PC each time. It cannot be said that it will improve.

The voice processing means described above enables voice input during the period from when the voice related to the first voice data corresponding to the part is output until the voice input time corresponding to the part elapses. You may make it have a means to control a microphone. In this way, for example, even in a factory with a high noise level, it becomes easy to specify a portion that is regarded as a confirmation result, and it is possible to prevent erroneous recognition of speech. In addition, when preparing correct voice data, the amount of data can be reduced.

  Furthermore, the correct answer data described above may be data representing the model number of a component that is regarded as a correct answer. In some cases, the confirmation instruction described above is an instruction that prompts the user to return the part model number as a confirmation result. In this way, it is possible to make the operator answer the model number one part at a time, and it is possible to prevent inspection errors caused by checking a plurality of parts collectively and inspection errors due to entry errors. .

  In addition, the inspection data storage unit described above may further store second audio data including a reconfirmation instruction that prompts the user to answer whether the part model number is correct or not. And the 2nd audio | voice data corresponding to each of the reconfirmation parts which are parts other than the part in which the portable terminal described above was correct by the 1st judgment means among the some parts contained in a specific apparatus. For each of the reconfirmation parts, and a means for outputting the sound related to the second audio data corresponding to the reconfirmation part via the earphone. Moreover, the second determination means for determining whether the reconfirmation part is correct or not based on the second input voice data input via the microphone for each of the reconfirmation parts by either the portable terminal or the central device. You may make it have further. In this way, since the check is performed in two stages, a more accurate inspection can be performed. In addition, even if it is erroneously recognized due to noise or the like, the original result can be obtained by reconfirmation.

  Further, according to another aspect of the present invention, it is possible to prevent an inspection error caused by checking a plurality of parts collectively.

  Furthermore, according to another aspect of the present invention, the influence of noise can be further reduced, for example, in a factory with high noise.

  FIG. 1 shows an outline of an inspection system according to an embodiment of the present invention. For example, in the network 1 which is an intranet or a cellular phone network, a central device 3 and a PDA (Personal Digital Assistant) 5 carried by a worker by lowering on his / her back (in FIG. 1, 5a, 5b,...). ) And are connected. The PDA 5 includes a hands-free set 6 (6a, 6b,... In FIG. 1) having a microphone and an earphone, and a two-dimensional code reader 7 for reading a two-dimensional code (for example, a QR (Quick Response code) code). The printer 8 and the lamp 9 are connected. Note that the hands-free set 6, the two-dimensional code reader 7, the printer 8, and the lamp 9 may perform wireless communication with the PDA 5 using, for example, Bluetooth (registered trademark). In some cases, the two-dimensional code reader 7, the printer 8, and the lamp 9 are incorporated in the PDA 5 in advance.

  The central device 3 reads the data receiving unit 31 that receives data from the PDA 5 and data necessary for the inspection (for example, voice data including instructions for the worker) from the inspection data storage unit 41 and transmits the data to the PDA 5. A test data processing unit 33 that performs processing such as the above, and a text conversion processing unit that performs processing for converting input voice data that is input through the microphone of the hands-free set 6 and includes the result of component confirmation into text data 35, a collation processing unit 37 that collates the text data converted by the text conversion processing unit 35 with correct data described later, and a two-dimensional code processing unit 39 that performs processing related to the two-dimensional code. .

  The central device 3 also includes a check data table 41 for storing a check item table, a first check table, and a second check table, which will be described later, and text used when converting input voice data into text data. A text conversion data storage unit 43 that stores conversion voice data and a collation result storage unit 45 that stores collation results by the collation processing unit 37 are managed.

  FIG. 2 shows a functional block diagram of the PDA 5. The PDA 5 includes a communication processing unit 51 that communicates with the central device 3 via the network 1, a control unit 53 that controls the hands-free set 6, the two-dimensional code reader 7, the printer 8, the lamp 9, and the like. An audio data input unit 55 that accepts input through the microphone of the hands-free set 6, an audio data output unit 57 that outputs audio related to the audio data through the earphones of the hands-free set 6, and audio data from the PDA 5 And an inspection data storage unit 59 for storing.

  3 to 6 show examples of data stored in the inspection data storage unit 41. FIG. FIG. 3 is an example of the check item table, and the check item table includes a two-dimensional code column, a check item column, and a storage column of correct data. In the two-dimensional code column, for example, a unique two-dimensional code capable of specifying a product is set in order to uniquely determine the product from purchase order data. In the check item column, a list of item IDs of items to be confirmed in the product corresponding to the two-dimensional code is set. Note that the contents of the items are predetermined in an item list as shown in FIG. For example, items of parts that are not standard equipment such as aero (item ID “12”) and navigation (item ID “29”) are listed in the check items of the products that the purchaser wishes to install. Is not included in the check items for products that did not want to be installed. Accordingly, the contents of the check items differ for each product. In addition, the correct data of the product corresponding to the two-dimensional code among the correct answer 1 column, correct answer 2 column,... Stored column information is set.

  FIG. 5 is an example of a first inspection table. The first inspection table includes an item ID column, a first audio data column, and a first microphone flag (1: microphone on / 0: microphone off). ), A first voice input time column, a correct answer 1 column, a correct answer 2 column, and so on. In the first audio data column, audio data including an instruction for the worker is stored. For example, the item ID “2” indicates that a voice “Please answer the tire specifications” is output. In the first microphone flag column, 1 (microphone on) is set when the item requires an answer from the operator (that is, when voice input is accepted), and an answer from the operator is required. In the case of a simple announcement that does not, 0 (microphone off) is set. In the first audio input time column, when the first microphone flag is 1, the time from turning on the microphone to turning it off is set. When the first microphone flag is 0, 0 is also set in the first audio input time column. Correct data for each product is set in each column of correct answer 1, correct answer 2,. In the present embodiment, it is assumed that correct data is prepared in advance according to the model number of the part included in the purchase order data, and based on this correct data, it is confirmed whether or not the finished product is as ordered. Shall.

  FIG. 6 is an example of the second inspection table. The second inspection table includes an item ID column, a second audio data column, and a second microphone flag (1: microphone on / 0: microphone off). ) And a second voice input time column. In the second audio data column, audio data including an instruction to the worker is stored. For example, the item ID “2” indicates that the voice “Is the tire specification“ radial RT-230-55 ”?” Is output. The first voice data includes an instruction to make the worker answer the part model number, but the second voice data makes the worker answer whether the part model number is correct (Yes / No). Such instructions are included. The second microphone flag and the second voice input time are set in the same manner as the first microphone flag and the first voice input time. In the example of FIG. 6, the second voice input time is set to a shorter time than the first voice input time because it is only necessary to accept voice input of correctness (Yes / No) of the part model number. Even if the item ID is the same, if the part model number is different, the content of the second audio data is also different, so a second inspection table is stored for each two-dimensional code.

  FIG. 7 shows an example of text conversion voice data stored in the text conversion data storage unit 43. FIG. 7 is an example of text conversion voice data related to “radial RT-230-55”. For example, even if an operator intends to utter “radial RT-230-55”, various voice waveforms (for example, FIG. 5) may vary depending on individual differences such as the manner of utterance (whether or not the vowel is lengthened or the accuracy of the English part). 7 and the like (speech waveforms 701 and 702). Here, if the speech waveform 702 is converted into a text “Radial R R-230-55”, the inspection result may change depending on the operator. Therefore, in the present embodiment, data of a plurality of similar speech waveforms are prepared, and even if the speech waveforms are slightly different due to individual differences such as the manner of utterance, “Radial RT-230-55” is similarly used. Enable text conversion. Specifically, a conversion destination character string is determined in advance for each text conversion voice data (the text conversion voice data 1, 2 and 3 are all “radial RT-230-55”), and work Text conversion voice data whose voice waveform matches the voice data input from the user is searched and converted into a conversion destination character string of the corresponding text conversion voice data. In this way, the voices of respondents with different utterance methods are handled as answers. As described above, since the microphone is turned on only for the first voice input time, a plurality of similar voice waveforms may be prepared with the first voice input time width as an upper limit. Thereby, the amount of data can be reduced.

  8 and 9 show an example of data stored in the collation result storage unit 45. FIG. FIG. 8 is an example of the collation result table, and the collation result table includes an item ID column and a collation result column. The verification result columns are further divided into a first inspection column and a second inspection column. In the first examination column, the collation result (O: matched / x: not matched) performed according to the data in the first examination table is set, and in the second examination column, according to the data in the second examination table. The executed verification result is set. The collation result table is stored for each two-dimensional code.

  FIG. 9 is an example of the mismatch item table, and the mismatch item table includes a two-dimensional code column and a mismatch item column. One of the two-dimensional codes in the check item table (FIG. 3) is set in the two-dimensional code column. In the mismatch item column, the item ID of the item in which “x” (mismatch) is set in the second examination column in the matching result table (FIG. 8) corresponding to the two-dimensional code is set. As will be described later, for each record, a new two-dimensional code is generated by coding the contents of the record.

  Next, processing of the inspection system shown in FIG. 1 will be described with reference to FIGS. First, the worker utters a predetermined phrase toward the microphone of the handsfree set 6 for the microphone test. The voice data input unit 55 of the PDA 5 receives voice input from the operator via the hands-free set 6 and adjusts the voice frequency and the like for generating voice data (FIG. 10: step S1). The communication processing unit 51 of the PDA 5 transmits information necessary for tuning to the central device 3 (step S3). Then, the data receiving unit 31 of the central device 3 receives the tuning information from the PDA 5 and stores it in the storage device (step S5).

  The operator brings the two-dimensional code reader 7 close to the two-dimensional code printed on, for example, a sticker attached to a product to be inspected. Then, the communication processing unit 51 of the PDA 5 transmits the two-dimensional code read by the two-dimensional code reader 7 to the central device 3 (step S7).

  The data receiving unit 31 of the central device 3 receives the two-dimensional code from the PDA 5 and stores it in the storage device (step S9). Then, the inspection data processing unit 33 of the central device 3 searches the check item table with the two-dimensional code stored in the storage device, and extracts the check item corresponding to the two-dimensional code (step S11). Then, the inspection data processing unit 33 of the central device 3 reads out the first audio data, the first microphone flag, and the first audio input time corresponding to each check item from the first inspection table, and transmits them to the PDA 5. (Step S13).

  The communication processing unit 51 of the PDA 5 receives the first voice data, the first microphone flag, and the first voice input time from the central device 3 and stores them in the test data storage unit 59 (step S15). Then, the audio data output unit 57 of the PDA 5 specifies unprocessed items in order from the top (step S17). Then, the voice data output unit 57 of the PDA 5 outputs the voice related to the first voice data of the specific item via the earphone of the handsfree set 6 (step S19). Thereafter, the processing shifts to the processing in FIG. 11 via the terminal A and the terminal B.

  Moving to the description of FIG. 11, after the terminal B, the audio data input unit 55 of the PDA 5 determines whether the first microphone flag of the specific item is 1 (FIG. 11: Step S21). If the first microphone flag of the specific item is 0 (step S21: No route), the process proceeds to step S27. On the other hand, when the first microphone flag of the specific item is 1 (step S21: Yes route), the voice data input unit 55 of the PDA 5 performs a voice input reception process (step S23).

  The voice input acceptance process will be described with reference to FIG. The voice data input unit 55 acquires the first voice input time of the specific item from the examination data storage unit 59 and sets it in the timer (FIG. 12: step S101). Then, the voice data input unit 55 turns on the microphone of the handsfree set 6 (step S103) and starts a timer. Although not shown, the operator may be informed that the microphone is on, for example, by turning on the lamp 9. The worker confirms the parts according to the sound output in step S19, and utters the confirmation result toward the microphone of the hands-free set 6.

  The voice data input unit 55 receives voice input from the operator via the microphone of the hands-free set 6 (step 105), and temporarily stores it as input voice data in the storage device. When the timer timeout is detected, the audio data input unit 55 sets the microphone off (step S107). Thereafter, the voice input acceptance process is terminated and the process returns to the original process.

  Returning to the description of FIG. 11, after the process of step S <b> 23, the communication processing unit 51 of the PDA 5 transmits the item ID of the specific item and the input voice data to the central device 3 (step S <b> 25). The audio data output unit 57 of the PDA 5 determines whether all items have been completed (step S27). If all items have not been completed (step S27: No route), the process returns to the process of step S17 (FIG. 10) via the terminal C. On the other hand, when all items have been completed (step S27: Yes route), the process proceeds to step S39.

  Further, after the terminal A, the data receiver 31 of the central device 3 receives the item ID and the input voice data from the PDA 5 and temporarily stores them in the storage device (step S29). Then, the text conversion processing unit 35 of the central device 3 performs text conversion processing on the input voice data to generate input text data (step S31). Specifically, the text conversion data storage unit 43 is searched based on the input voice data, and the text conversion voice data whose voice waveform matches the input voice data is detected. At this time, the input voice data is adjusted using the tuning information as necessary. Then, data including the conversion destination character string of the detected text conversion voice data is generated and stored in the storage device as input text data. If text conversion voice data whose voice waveform matches the input voice data cannot be detected, a conventional text conversion process is performed to convert the input voice data into input text data.

  Thereafter, the collation processing unit 37 of the central device 3 collates the input text data and the correct answer data, and stores the collation result in the first examination column of the corresponding item in the collation result table (step S33). The correct data to be collated is specified based on the two-dimensional code and the item ID. Thereafter, the collation processing unit 37 of the central device 3 determines whether all items have been completed (step S35). If all items have not been completed (step S35: No route), the process returns to step S29. On the other hand, when all items have been completed (step S35: Yes route), the collation processing unit 37 of the central device 3 transmits the collation result to the PDA 5 (step S37). The communication processing unit 51 of the PDA 5 receives the collation result from the central device 3 and temporarily stores it in the storage device (step S39).

  And the collation process part 37 of the central apparatus 3 judges whether all the collation results are in agreement (step S41). When all the collation results are coincident (step S41: Yes route), the process ends here (step S43). On the other hand, if all the matching results do not match (step S41: No route), the process proceeds to the process of FIG.

  In addition, the control unit 53 of the PDA 5 determines whether all the matching results are the same (step S45). If all the matching results are coincident (step S45: Yes route), the process is terminated here (step S47). On the other hand, if all the collation results do not match (step S45: No route), the processing shifts to the processing in FIG.

  Shifting to the description of FIG. 13, after the terminal D, the inspection data processing unit 33 of the central device 3 identifies an item whose collation result does not match as a re-inspection item (FIG. 13: step S49). Specifically, an item for which “x” (mismatch) is set in the first examination column of the matching result table is specified as a re-inspection item. Then, the inspection data processing unit 33 of the central device 3 specifies the second inspection table corresponding to the two-dimensional code stored in the storage device (step S51). Then, the inspection data processing unit 33 of the central device 3 reads out the second audio data, the second microphone flag, and the second audio input time corresponding to the re-inspection item from the specified second inspection table, and stores them in the PDA 5. Transmit (step S53).

  In addition, after the terminal E, the communication processing unit 51 of the PDA 5 receives the second voice data, the second microphone flag, and the second voice input time from the central device 3 and stores them in the test data storage unit 59. (Step S55). Then, the audio data output unit 57 of the PDA 5 specifies unprocessed items in order from the top (step S57). Then, the voice data output unit 57 of the PDA 5 outputs the voice related to the second voice data of the specific item via the earphone of the handsfree set 6 (step S59). Thereafter, the processing shifts to the processing in FIG. 14 via the terminal F and the terminal G.

  Moving to the description of FIG. 14, after the terminal G, the audio data input unit 55 of the PDA 5 determines whether the second microphone flag of the specific item is 1 (FIG. 14: Step S61). If the second microphone flag of the specific item is 0 (step S61: No route), the process proceeds to step S67. On the other hand, when the second microphone flag of the specific item is 1 (step S61: Yes route), the voice data input unit 55 of the PDA 5 performs a voice input reception process (step S63). Note that the voice input acceptance process is basically the same as the process described above, and thus a detailed description thereof is omitted. However, in the process of step S63, the second voice is used instead of the first voice input time. Use input time.

  And the communication processing part 51 of PDA5 transmits item ID and input audio | voice data of a specific item to the central apparatus 3 (step S65). The input voice data is data received in the voice input reception process (step S63). The audio data output unit 57 of the PDA 5 determines whether all items have been completed (step S67). If all items have not been completed (step S67: No route), the process returns to the process of step S57 (FIG. 13) via the terminal H. On the other hand, when all items have been completed (step S67: Yes route), the process proceeds to step S79.

  Further, after the terminal F, the data receiver 31 of the central device 3 receives the item ID and the input voice data from the PDA 5 and temporarily stores them in the storage device (step S69). As described above, since the second voice data includes an instruction for prompting the user to reply whether the part model number is correct (Yes / No), the input voice data includes the part model number. Correctness is included. Then, the text conversion processing unit 35 of the central device 3 performs a conventional text conversion process on the input voice data to generate input text data (step S71).

  And the collation process part 37 of the central apparatus 3 stores a collation result in the column of the 2nd test | inspection of the applicable item in a collation result table according to input text data (step S73). Specifically, if the input text data contains an answer that the part model number is correct (Yes), “O” (match) is stored as the matching result; otherwise, the matching result is Stores “x” (mismatch).

  Thereafter, the collation processing unit 37 of the central device 3 determines whether all items have been completed (step S75). If all items have not been completed (step S75: No route), the process returns to step S69. On the other hand, when all items have been completed (step S75: Yes route), the collation processing unit 37 of the central device 3 transmits the collation result to the PDA 5 (step S77). The communication processing unit 51 of the PDA 5 receives the collation result from the central device 3 and temporarily stores it in the storage device (step S79).

  And the collation process part 37 of the central apparatus 3 judges whether all the collation results are in agreement (step S81). If all the matching results are coincident (step S81: Yes route), the process is terminated here (step S83). On the other hand, if all the collation results do not match (step S81: No route), the processing shifts to the processing in FIG.

  In addition, the control unit 53 of the PDA 5 determines whether all the matching results are the same (step S85). If all the collation results are coincident (step S85: Yes route), the process ends here (step S87). On the other hand, if all the collation results do not match (step S45: No route), the processing shifts to the processing in FIG.

  Shifting to the description of FIG. 15, after the terminal I, the two-dimensional code processing unit 39 of the central device 3 generates a record including the item ID and the two-dimensional code of the items whose matching results do not match, and the mismatching item table (FIG. 15: Step S89). That is, the item ID of the item for which “x” (mismatch) is set in the second examination column of the matching result table is registered in the mismatch item table. Then, the two-dimensional code processing unit 39 of the central device 3 generates a new two-dimensional code by encoding the contents of the record, and temporarily stores it in the storage device (step S89). Then, the two-dimensional code processing unit 39 of the central device 3 transmits the generated two-dimensional code data (for example, data before being imaged) to the PDA 5 (step S93).

  Further, after the terminal J, the communication processing unit 51 of the PDA 5 receives the data of the two-dimensional code from the central device 3 and temporarily stores it in the storage device. Then, the control unit 53 of the PDA 5 images the two-dimensional code and outputs a print instruction to the printer 8 (step S95). For example, the printer 8 prints the imaged two-dimensional code on a sticker or the like in accordance with a print instruction from the PDA 5. The operator attaches the printed sticker to a predetermined place on the product. For example, in the next step, a two-dimensional code printed on a sticker is read by a two-dimensional code reader, and a unique value that can identify the product and a part determined to be inconsistent are found. It becomes possible to easily identify whether or not is determined to be inconsistent.

  By performing the processing as described above, for example, when checking each part included in a product such as an automobile, the operator can use both hands, which leads to improvement in work efficiency. Moreover, since the operator answers the model number for each part, it is possible to prevent an inspection error caused by checking a plurality of parts together. Since the voice input time is provided and the voice input is accepted in a certain time zone, the erroneous recognition due to noise or the like can be further reduced. Note that even if a recognition error occurs due to noise or the like, the original result can be obtained because reconfirmation is performed.

  Although one embodiment of the present invention has been described above, the present invention is not limited to this. For example, the functional block diagram described above does not necessarily correspond to an actual program module configuration. The central device 3 may be realized by a plurality of computers instead of a single computer.

  Further, the configuration of each table described above is an example, and the configuration as described above is not necessarily required. Further, in the processing flow, the processing order can be changed if the processing result does not change.

  In the above, the input voice data is transmitted from the PDA 5 to the central device 3, and the central device 3 registers the text conversion process, the collation process with the correct answer data, the reexamination item specifying process, and the mismatch item table. Although an example of performing the power record generation process has been described, it is possible to adopt a configuration in which at least a part of these processes is performed by the PDA 5.

  In the above description, an example of performing a two-stage inspection of a first inspection for answering the part model number and a second inspection for answering whether the part model number is correct has been described. Instead of immediately moving to the second inspection, it is possible to adopt a configuration in which the first inspection is re-executed with respect to items whose matching results do not match.

  The central device 3 is a computer device as shown in FIG. 16, and a display control unit 2507 connected to a memory 2501 (storage device), a CPU 2503 (processing device), a hard disk drive (HDD) 2505, and a display device 2509. A drive device 2513 for the removable disk 2511, an input device 2515, and a communication control unit 2517 for connecting to a network are connected by a bus 2519. An operating system (OS: Operating System) and an application program for performing processing in the present embodiment are stored in the HDD 2505, and are read from the HDD 2505 to the memory 2501 when executed by the CPU 2503. If necessary, the CPU 2503 controls the display control unit 2507, the communication control unit 2517, and the drive device 2513 to perform necessary operations. Further, data in the middle of processing is stored in the memory 2501 and stored in the HDD 2505 if necessary. In the embodiment of the present invention, an application program for performing the processing described above is stored in the removable disk 2511 and distributed, and is installed in the HDD 2505 from the drive device 2513. In some cases, the HDD 2505 may be installed via a network such as the Internet and the communication control unit 2517. Such a computer device realizes various functions as described above by organically cooperating the hardware such as the CPU 2503 and the memory 2501 described above with the OS and necessary application programs. The PDA 5 does not have the HDD 2505 or the drive device 2513, but basically has the same configuration as that in FIG.
