(Embodiment)
FIG. 1 is a diagram illustrating a schematic configuration of a forgotten object detection system 1 according to the embodiment. As shown in FIG. 1, the forgotten object detection system 1 includes a mobile phone 10, an RFID (Radio Frequency IDentification) 50, and a schedule input device 70. The mobile phone 10 can communicate with other communication devices via a communication network.

  The mobile phone 10 is a mobile communication device carried by a student (student). The students include, for example, nursery school children, kindergarten children, elementary school students, and junior high school students. As shown in the example of FIG. 1, the mobile phone 10 is configured to be attached to a basket 5 used by students to carry educational materials when they go to school. The bag 5 may be a school bag, a rucksack, a handbag or the like. The mobile phone 10 may be attached to a student's clothes or body when attending school.

  The RFID 50 is a wireless tag. The RFID 50 is provided on the articles 2a to 2n, which are objects to be detected. The articles 2a to 2n are teaching materials used in classes or events at a school (nursery school or kindergarten). The teaching materials include, for example, textbooks, side readers, dictionaries, notebooks, gym clothes, musical instruments, and various tools. The RFID 50 is affixed to the articles 2a to 2n by a student guardian or the like. The RFID 50 may be provided in advance in the articles 2a to 2n. The articles 2a to 2n provided with the RFID 50 are carried between the house and the school in a state of being accommodated in the bag 5 as necessary.

  The RFID 50 has tag data for identifying the articles 2a to 2n. In the following description, tag data may be referred to as ID for the sake of simplicity. The tag data of the RFID 50 is read by a reader that the mobile phone 10 has.

  The schedule input device 70 is a device to which schedule data is input. The schedule data includes a schedule related to a school lesson or event and information related to an article used in the lesson or event. The information regarding the article used in the lesson or the event is configured so that the ID of the RFID 50 provided in the article can be specified.

  The schedule input device 70 is configured to be able to communicate with the mobile phone 10. Communication between the schedule input device 70 and the mobile phone 10 may be realized through a public line, or a short distance such as a wireless LAN, Bluetooth (registered trademark), NFC (Near Field Communication), infrared communication, etc. It may be realized via a wireless line or may be realized via a wired cable. The schedule input device 70 transmits the input schedule data to the mobile phone 10.

  The schedule input device 70 may be any electronic device such as a mobile phone, a personal computer, or a server. The person who inputs the schedule data to the schedule input device 70 may be any person such as a student, a guardian of the student, or a school official. The transmission of schedule data from the schedule input device 70 to the mobile phone 10 can be realized by using various techniques used for synchronizing data between electronic devices, for example.

  How the lost item is detected in the lost item detection system 1 shown in FIG. 1 will be described. FIG. 2 is a flowchart showing a processing procedure in which the mobile phone 10 detects forgotten things. As shown in FIG. 2, the mobile phone 10 detects the movement of the mobile phone 10 as step S1. Specifically, the mobile phone 10 detects a movement out of the house. Moving out of the house includes moving in the house to get out, moving when going out of the house, and moving just out of the house (moving within a specified range from the house). included.

  When the movement is detected in this manner, the cellular phone 10 reads the ID using a reader in step S2. Thereby, ID is read from RFID50 provided in articles | goods 2a-2n which exists in the readable range of a reader | leader. The reader of the mobile phone 10 can read the ID of the RFID 50 provided in the articles 2a to 2n accommodated in the bag 5 and other handbags, etc., but is a predetermined distance (for example, 2 to 3 m) from the bag 5. ) The ID of the RFID 50 provided on the distant article has a readable range that cannot be read. For this reason, in step S2, the IDs of the RFIDs 50 provided on all the articles 2a to 2n possessed by the student are read, but the IDs of the RFIDs 50 provided on the other articles are rarely read.

  Subsequently, in step S3, the mobile phone 10 extracts the ID of the RFID 50 provided in the article to be held among the articles 2a to 2n based on the schedule data. Specifically, the mobile phone 10 extracts information related to an article used in a class or event scheduled for the day, and specifies an ID corresponding to the article included in the extracted information. The execution order of step S2 and step S3 may be reversed, and step S2 and step S3 may be executed in parallel.

  Subsequently, in step S4, the mobile phone 10 compares the ID read in step S2 with the ID extracted in step S3 to detect forgotten items. Specifically, if there is an ID extracted in step S3 but not read in step S2, the article corresponding to the ID is a forgotten item. When a forgotten item is detected, the mobile phone 10 notifies the forgotten item in step S5. The notification may be implemented so as to notify the presence of a forgotten item by displaying a message or symbol on the display unit, sound, voice, blinking of a lamp, vibration, etc. You may mount so that it may display on a display part.

  As described above, the mobile phone 10 extracts the ID of the RFID 50 provided in the article to be held among the articles 2a to 2n based on the schedule data, and the extracted ID and the article stored in the bag 5 The ID read from the RFID 50 provided in the ID is collated. For this reason, forgotten things are detected without having to manually check the articles contained in the basket 5 one by one. As a result, the mobile phone 10 can reduce the possibility of forgotten things without bothering the user.

  Furthermore, the cellular phone 10 executes a process of detecting forgotten things when triggered by the detection of movement. For this reason, the process of detecting forgotten things is automatically executed when the student has the mobile phone 10 and moves to leave the house. Since this timing is a timing at which all necessary articles should be held, it is suitable as a timing for inspecting forgotten items. As a result, the mobile phone 10 can inspect forgotten things at a suitable timing without bothering the user.

  FIG. 3 is a block diagram showing a functional configuration of the mobile phone 10.

The communication method includes, for example, an electromagnetic induction method, an electromagnetic coupling method, a radio wave method, and the like. The reader 19 is configured to receive each ID from a plurality of RFIDs 50 within the readable range. Each time the reader 19 receives information from the plurality of RFIDs 50, the reader 19 may output the received information to the control unit 100. Alternatively, the reader 19 may collectively output information received from the plurality of RFIDs 50 to the control unit 100.

  The mobile phone 10 may have a reader / writer instead of the reader 19. That is, the mobile phone 10 may have not only a function of reading information from the RFID 50 but also a function of writing information to the RFID 50.

  The audio processing unit 20 performs processing of an audio signal input to the microphone 11 and an audio signal output from the speaker 12 and the receiver 13. That is, the audio processing unit 20 amplifies the audio input from the microphone 11 and performs analog-digital conversion, and then performs signal processing such as encoding to convert the digital audio data to the control unit 100. Send it out. The audio processing unit 20 performs processing such as decoding, digital-analog conversion, and amplification of the audio data sent from the control unit 100, converts it into an analog audio signal, and outputs it to the speaker 12 and the receiver 13.

  The storage unit 40 stores various programs and various data used for processing in the control unit 100 such as an operating system program and an application program. For example, the storage unit 40 includes a task for operating an application program for controlling the operation of the display unit 15, a task for operating an application program for controlling the operation of the communication unit 17, and an application program for controlling the operation of the audio processing unit 20. Tasks to be activated are stored. In addition to these tasks, the storage unit 40 includes, for example, downloaded voice data, or an address book in which a program used by the control unit 100 to control the storage unit 40, a telephone number and a mail address of a communication partner are described. Voice files such as dial tone and ring tone, temporary data used in the process based on the program, and the like are stored.

  In the present embodiment, the storage unit 40 includes a data storage area 41. The data storage area 41 is an area in which various data used by the control unit 100 is stored. In the data storage area 41, for example, an ID read from the RFID 50 is stored.

  The storage unit 40 stores various data such as schedule data 42, article data 43, and setting data 44. The schedule data 42 includes information for specifying a schedule related to a school lesson or event. The article data 43 includes information for associating a schedule with the ID of the RFID 50 attached to the articles 2a to 2n used in the schedule. The setting data 44 includes information related to various settings related to the operation of the mobile phone 10.

  Next, the schedule data 42 will be described with reference to FIG. FIG. 4 is a diagram illustrating an example of the schedule data 42. As shown in FIG. 4, the schedule data 42 includes timetable information for each day of the week corresponding to the student who has the mobile phone 10. The timetable information includes items indicating schedules (class subjects, event types, etc.) to be performed for each time period.

  In the example shown in FIG. 4, the timetable information corresponding to Monday is “National language” for the 1st period, “arithmetic” for the 2nd period, “Society” for the 3rd period, “Physical education (swimming)” for the 4th period, “ "Science" is set. In the timetable information corresponding to Tuesday, “ball game tournament” is set for 1 to 3 time periods, “society (geography)” for 4 time periods, and “physical education” for 5 time periods. In this way, information is set in each timed schedule so that articles used in classes or events can be specified. For example, the example shown in FIG. 4 includes “physical education” and “physical education (swimming)” as schedules. “Physical education” represents a physical education class conducted at a playground or gymnasium, and gymnastics is required in this class. "Physical education (swimming)" represents a physical education class held in the pool, and this class requires a swimsuit. In this way, in the schedule data 42, even if the subject is the same, if there is a lesson with different articles used, information is set so that they can be distinguished.

  Next, the article data 43 will be described with reference to FIG. FIG. 5 is a diagram illustrating an example of the article data 43. As shown in FIG. 5, the article data 43 includes items such as a schedule, an article name, and an ID. In the schedule item, a value corresponding to the schedule included in the schedule data 42 is set. In the item name item, a value indicating an item used in a class or event set in the scheduled item is set. In the ID item, the ID of the RFID 50 provided in the article used in the lesson or event set in the scheduled item is set.

  In the example shown in FIG. 5, in the first data of the article data 43, “National language” is set as the scheduled item. Furthermore, in this data, “textbook” is set in the item name item, information in which the ID of the RFID 50 provided in the textbook is set in the ID item, and “notebook” is set in the item name item. The ID item includes information in which the ID of the RFID 50 provided in the notebook is set. This data shows that “textbook” and “notebook” are used in the class of “Japanese language”. As described above, the article data 43 is configured to be able to cope with a case where a plurality of articles are used in a lesson or an event.

  In the present embodiment, the case where the schedule data 42 and the article data 43 are provided separately will be described. However, the schedule data 42 may be configured to include the article data 43. For example, the timetable information for each day of the week may be configured to include an ID of an article used in the schedule in addition to the schedule for each time period.

  Next, the setting data 44 will be described with reference to FIG. FIG. 6 is a diagram illustrating an example of the setting data 44. The setting data 44 includes condition information indicating conditions under which the mobile phone 10 detects forgotten things. The condition information includes items such as a time zone and a region. The time zone indicates a time zone in which detection of forgotten things is executed. The area indicates a range in which detection of a forgotten object is executed when going out from there. In the condition information time zone item, a time zone in which the student leaves the house is set. Information indicating the range of the student's house or a range in the vicinity thereof is set in the item of the condition information area.

  The control unit 100 executes processing based on various programs stored in the storage unit 40. The control unit 100 includes, for example, a microprocessor (MPU: Micro Processing Unit). The control unit 100 sequentially reads instruction codes from the program stored in the storage unit 40, and executes various processes of the mobile phone 10 according to procedures instructed by the read instruction codes. That is, the control unit 100 displays the display unit so that various processes of the mobile phone 10 are executed in an appropriate procedure according to the operation of the operation unit 14 and the program stored in the storage unit 40 of the mobile phone 10. 15, the operation of the camera 16, the communication unit 17, the acceleration sensor 18, the reader 19, the voice processing unit 20, and the like are controlled.

  The control unit 100 functions as a position acquisition unit that acquires the current position of the mobile phone 10 by executing a positioning process. The control unit 100 performs positioning based on the radio signal received by the communication unit 17 from the GPS satellite. The control unit 100 may perform positioning by another method instead of or in addition to the method using the radio signal received by the communication unit 17 from the GPS satellite. For example, the control unit 100 may perform positioning based on identification information of one or a plurality of base stations or access points from which the communication unit 17 is receiving radio. In this case, the control unit 100 may perform positioning by comparing previously registered information with identification information, or may inquire about a position corresponding to the identification information via the communication unit 17. The control unit 100 may perform positioning using the intensity of radio waves received from the base station or access point.

  The control unit 100 requests the reader 19 to read the ID of the RFID 50 by executing a reading process. The control unit 100 stores the ID input from the reader 19 in response to the request in the data storage area 41 of the storage unit 40 as the read ID.

  The control unit 100 detects the movement of the mobile phone 10 by executing a movement detection process. The control unit 100 determines that the movement has been detected when the current position obtained by the positioning process is outside the area indicated by the condition information of the setting data 44. When the position obtained by the positioning process is not outside the area indicated by the condition information of the setting data 44, the control unit 100 determines that the movement is not detected.

  FIG. 7 is a block diagram of the RFID 50. As shown in FIG. 7, the RFID 50 includes a transmission / reception unit 51 and a memory 52. The transmission / reception unit 51 includes an antenna 51a, and performs communication using the communication method with the reader 19 of the mobile phone 10 via the antenna 51a. The memory 52 stores unique identification data (ID) for identifying the RFID 50. When the RFID 50 receives a radio wave from the reader 19, the RFID 50 generates an induced voltage by the received radio wave and generates power. The RFID 50 uses the power to transmit a reflected wave indicating the ID stored in the memory 52 to the reader 19.

  So far, the basic configuration of the forgotten object detection system 1 according to the present embodiment has been described. Below, with reference to FIG. 8, how the control part 100 of the mobile telephone 10 detects a thing left behind is demonstrated. FIG. 8 is a flowchart illustrating an example of a processing procedure for detecting forgotten things. The processing procedure shown in FIG. 8 is repeatedly executed when the current time is within the time zone set in the condition information of the setting data 44.

  As shown in FIG. 8, the control unit 100 determines whether or not movement is detected as step S101. Specifically, the control unit 100 acquires the current position by the positioning process, and determines that the movement has been detected if the current position is outside the region set in the condition information of the setting data 44. When it is determined that the movement is not detected (No), the control unit 100 ends this processing procedure. When it is determined that the movement is detected (Yes), the control unit 100 proceeds to step S102.

  In step S102, the control unit 100 requests the reader 19 to read the ID. The reader 19 reads the ID from the RFID 50 and outputs the read ID to the control unit 100. In step S103, the control unit 100 stores the ID read from the RFID 50 in the data storage area 41 of the storage unit 40.

  In step S104, the control unit 100 acquires date information indicating the current date. In step S105, the control unit 100 extracts the ID of the RFID 50 provided in the articles 2a to 2n to be possessed based on the date information and the schedule data 42. Specifically, the control unit 100 extracts the schedule of the date (day of the week) indicated by the date and time information from the schedule data 42 and acquires the ID of the article used in each schedule from the article data 43.

  For example, when the day of the week is specified as “Monday”, the control unit 100 determines, based on the timetable information of “Monday” shown in FIG. Extract “Science” schedule. The control unit 100 acquires the IDs of the articles corresponding to those schedules from the ID item of the article data 43 as the ID of the RFID 50 provided in the articles 2a to 2n to be possessed.

  Subsequently, in step S106, the control unit 100 collates the ID extracted in step S105 with the ID read in step S102 to detect forgotten items, and stores the detection result in the storage unit 40. Specifically, the control unit 100 does not detect forgotten items when all the IDs extracted in step S105 are read. If there is an ID that has been extracted in step S105 but has not been read, the control unit 100 detects forgotten things.

  In step S107, the control unit 100 determines whether a forgotten item is detected. When it is determined that the forgotten item is not detected (No), the control unit 100 ends this processing procedure. When it is determined that the forgotten thing is detected (Yes), the control unit 100 notifies the forgotten thing in step S108, and ends this processing procedure.

  In the present embodiment, the control unit 100 creates notification information for notifying students of forgotten things, displays the generated notification information on the display unit 15, and outputs a notification sound from the speaker 12 or the like. As for the method of notifying a lost item, the articles 2a to 2n corresponding to the lost item may be notified by notification information.

  As described above, in this embodiment, forgotten items are detected based on the ID of the RFID 50 provided in the articles 2a to 2n and the schedule data 42. For this reason, forgotten things are detected without bothering the user. Furthermore, in the present embodiment, forgotten object detection processing is executed in response to detection of movement (leaving home). For this reason, the forgotten object detection process is executed at a suitable timing.

  Embodiment which this application discloses can be changed in the range which does not deviate from the summary and range of invention. Furthermore, the embodiment disclosed in the present application and its modifications can be combined as appropriate. For example, the above embodiment may be modified as follows.

  In the above embodiment, an example of detecting a student's forgotten thing has been described. However, the forgotten object detection system 1 can also be used to detect forgotten things for users other than students. For this purpose, the forgotten object detection system 1 is configured with schedule data 42 so that the schedule of the user of the mobile phone 10 can specify the ID of the RFID 50 provided on the article used in each schedule. Just do it.

  In the above embodiment, an example has been shown in which the mobile phone 10 detects a forgotten item of an article whose necessity varies day by day, such as an article used in a class or an event. However, the mobile phone 10 may be configured to be able to detect forgotten items other than items whose needs vary daily. Goods other than goods whose necessity fluctuates from day to day are goods that are necessary almost every day, such as commuter passes, name tags, and student ID cards. Specifically, the schedule data is configured so that the RFID ID provided on these articles is extracted every day as the ID of the article to be possessed so that the mobile phone 10 can detect forgotten items of these articles. Also good. Or you may provide the data for specifying the information of ID of RFID provided in these articles separately from schedule data.

  By allowing for the detection of forgotten items other than those whose needs fluctuate from day to day, these forgotten items are detected at the same time as forgotten items used for classes or events. For this reason, the student can reduce the possibility of forgetting things other than the goods whose necessity fluctuates every day, and is less likely to be bothered by dealing with forgotten things over and over.

  In the above embodiment, an example in which the mobile phone 10 and the schedule input device 70 are provided separately has been described. However, the mobile phone 10 may have the function of the schedule input device 70. That is, the mobile phone 10 may be configured so that the schedule data 42 can be registered and maintained.

  In the above embodiment, the movement is detected based on whether or not the current position obtained by the positioning process is outside the preset region. However, the movement detection method is not limited to this. Further, the detected movement may be a movement other than the movement when leaving the house.

  For example, the mobile phone 10 may count the number of steps of the student and detect movement based on the counted number of steps. In this case, the control unit 100 counts the number of steps of the student based on the change in acceleration detected by the acceleration sensor 18. The control unit 100 stores the counted number of steps in the data storage area 41. The counted number of steps is cleared at a predetermined timing (a timing when the date changes, a timing when a predetermined period elapses, etc.). The number of steps may be counted only when the current time is within the time zone set in the condition information of the setting data 44.

  And the control part 100 detects a movement, when the counted step count exceeds a predetermined threshold value. The threshold value here is, for example, the number of steps assumed not to exceed while the student moves in the house while holding the mobile phone 10, that is, the number of steps assumed that the student is outside the house. It may be. Alternatively, if it can be determined whether or not the mobile phone 10 is moving in a state where it is attached to the bag 5 based on the acceleration detection pattern, the threshold is set to several steps, and the mobile phone 10 is attached to the bag 5 The movement may be detected when the number of steps exceeds a threshold value in the determined state.

  Alternatively, the mobile phone 10 may detect movement when communication with a predetermined communication device becomes impossible or when communication is possible. For example, the mobile phone 10 may detect movement when communication with a wireless LAN device or Bluetooth (registered trademark) device installed in a student's room becomes impossible. For example, the mobile phone 10 may detect movement when a reader reads an RFID ID attached to the entrance of a student's house.

  Or the mobile telephone 10 may detect a movement using RFID50 provided in articles | goods 2a-2n, and may perform the detection process of a thing left behind. With reference to FIG. 9, an example of control in the case of detecting movement using the RFID 50 provided in the articles 2a to 2n in the forgotten object detection system 1 will be described. FIG. 9 is a flowchart illustrating an example of a processing procedure for detecting forgotten things when an ID cannot be read. The processing procedure shown in FIG. 9 is repeatedly executed when the current time is within the time zone set in the condition information of the setting data 44. In this example, the reader 19 has a readable range that can read the ID of the RFID 50 existing in the student's room or in the student's house.

  As illustrated in FIG. 9, the control unit 100 requests the reader 19 to perform reading in step S <b> 201. The reader 19 reads the ID from the RFID 50 and outputs the read ID to the control unit 100. In step S202, the control unit 100 stores the ID read from the RFID 50 in the data storage area 41 of the storage unit 40.

  In step S203, the control unit 100 collates the read ID with the previously read ID, and determines whether there is an ID that cannot be read based on the collation result. When there is no ID that can no longer be read (No), the control unit 100 determines that no movement is detected, and ends this processing procedure. If there is an ID that cannot be read (Yes), the control unit 100 determines that movement has been detected, and proceeds to step S204. In the student's room, there is also an RFID 50 provided on an article that is not used for the lesson and event of the day. When the mobile phone 10 is located in the student's room, the reader 19 also reads the ID of the RFID 50. . However, when the mobile phone 10 moves out of the room or out of the house, the reader 19 cannot read the ID of the RFID 50. For this reason, a movement can be detected by collating the read ID with the ID read last time.

  In step S204, the control unit 100 acquires date / time information indicating the current date / time. In step S205, the control unit 100 extracts the ID of the RFID 50 provided in the articles 2a to 2n to be possessed based on the date information and the schedule data 42. In step S <b> 206, the control unit 100 compares the extracted ID with the read ID to detect a forgotten item, and stores the detection result in the storage unit 40.

  In step S207, the control unit 100 determines whether a forgotten item is detected based on the detection result of the storage unit 40. When it is determined that the forgotten item is not detected (No), the control unit 100 ends this processing procedure. When it is determined that the forgotten thing is detected (Yes), the control unit 100 notifies the forgotten thing in step S208 and ends this processing procedure.

  Thus, the mobile phone 10 can also detect movement using the RFID 50 provided in the articles 2a to 2n. In this system, the mobile phone 10 can also detect movement using the reader 19 used to detect forgotten things. For this reason, the mobile phone 10 can detect movement without providing other devices such as an acceleration sensor and a GPS receiver, and the configuration can be simplified.

  The mobile phone 10 may use a combination of methods for detecting movement. For example, in order to increase the detection accuracy of movement, the mobile phone 10 detects movement using a plurality of methods in combination, and when movement is detected by all methods, or movement is detected by a predetermined number of methods. In this case, a process for detecting forgotten objects may be executed.

  In the above-described embodiment, a case has been described in which a forgotten item is detected when the mobile phone 10 detects movement, but the mobile phone 10 may be configured to detect a forgotten item at a predetermined time. For example, a predetermined time is set in the condition information of the setting data 44. When detecting the predetermined time, the mobile phone 10 reads the ID from the RFID 50 of the bag 5. As described above, the mobile phone 10 compares the extracted ID with the read ID to detect forgotten items. The predetermined time is, for example, the time when the student should have the necessary items for a class or event, or the time when the student leaves the house for attending school.

  As described above, the mobile phone 10 can read the ID of the RFID 50 and detect forgotten things based on the schedule data 42 when detecting a predetermined time. For this reason, since the cellular phone 10 can detect a forgotten thing at a predetermined time desired by the student, the student can check the forgotten thing at a convenient time.

  In the embodiment described above, the case where the RFID 50 is a passive tag (passive tag) has been described, but the RFID 50 may use, for example, an active tag (active tag) or a semi-active tag (activation type active tag).

  In the above-described embodiment, the case where the schedule data 42 of the mobile phone 10 has timetable information has been described, but the present invention is not limited to this. The schedule data 42 may be configured differently depending on the destination of the articles 2a to 2n. The destination includes, for example, a school, a learning school, and a sports club. Alternatively, the destination may be any combination of school, school, and sports club.

  FIG. 10 is a diagram illustrating an example of schedule data 42A corresponding to a school and a learning cram school. In the example shown in FIG. 10, the schedule data 42A includes time zone information for each day of the week. The time zone information includes items such as a time zone and a schedule. For example, the time zone information corresponding to Monday is “National language” for 1 period, “arithmetic” for 2 periods, “society” for 3 periods, “physical education (swimming)” for 4 periods, “science” for 5 periods, and after school Is set to “Cram School”. When the schedule includes “learning school”, article information in which “learning school” is set as the scheduled item is used. As described above, the schedule data 42A can be configured to include a schedule of a school and a learning cram school. For this reason, the mobile phone 10 can detect forgotten items of both the school and the cram school based on the read ID of the RFID 50 and the schedule data 42A.

  FIG. 11 is a diagram illustrating an example of schedule data 42B corresponding to a date and a time zone. In the example shown in FIG. 11, the schedule data 42B includes time zone information for each date. The time zone information includes items such as a time zone and a schedule. For example, the time zone information includes time zones such as “9:00 to 10:00”, “10:00 to 11:00”, “11:00 to 12:00”, and the like. The schedule of time zone information indicates a schedule corresponding to the time zone. The schedule includes, for example, subjects, learning cram schools and the like. Furthermore, when the mobile phone 10 detects a forgotten thing of a user other than a student, the schedule includes, for example, a meeting, a presentation, a meeting, and the like.

  The schedule data 42 of the mobile phone 10 described above can be changed as appropriate by changing the schedule, for example. For example, when an event such as an athletic meet is postponed, the schedule input device 70, the server on the school side, etc. change the schedule data 42 of the mobile phone 10. For example, the schedule input device 70, the school server, or the like supplies change information for changing the schedule data 42 to the mobile phone 10 or supplies new schedule data 42 to the mobile phone 10. When the mobile phone 10 changes the schedule data 42 in the storage unit 40, the mobile phone 10 detects a forgotten item based on the changed schedule data 42. Therefore, the cellular phone 10 can detect forgotten things based on the latest schedule data 42 even when the schedule is changed. Furthermore, if the cellular phone 10 notifies the student that the schedule has been changed, the student can recognize the reason why the lost item has occurred.

  In the embodiment described above, the case where the mobile phone 10 stores the schedule data 42 and the article data 43 in the storage unit 40 has been described. However, the present invention is not limited to this. The schedule data 42 and the article data 43 may be stored in, for example, a schedule input device 70, a server on the school side that can communicate via a network, and the mobile phone 10 may be referred to as necessary. Good.
