Further, of the data storage units 003a and 003b included in the data portable device 001, the attitude of the data portable device 001 is adjusted so that the data storage unit 003a or 003b storing the data to be transferred is on the data storage device 101 side. To do. For example, when it is desired to transfer data between the data storage unit 003 a and the data storage device 101, the data portable device 001 is arranged with the attitude shown in FIG. 4, while the data storage unit 003 b and the data storage device 101 are When it is desired to transfer data between them, the portable data device 001 is arranged in the posture shown in FIGS.

  Subsequently, the user operates the data portable device 001 to instruct data transfer from the data portable device 001 to the data storage device 101 by, for example, operating an operation unit (not shown).

  In response to this instruction, the data portable device 001 obtains a relative positional relationship (attitude) with respect to its own data storage device 101, and based on the obtained orientation, the two data storage units 003a and 003b included in itself. The data portable device 001 and the data storage device 101 specify which is the access target, and then transfer the stored data of the specified data storage unit 003a or 003b to the data storage device 101.

  Hereinafter, the operation of each part will be described for each scene.

  First, a method for detecting the attitude of the data portable device 001 will be described with reference to FIG. 1, FIG. 4, and FIG.

  Here, as shown in FIG. 1, it is assumed that the data portable device 001 is mounted on the data storage device 101 such that the longitudinal direction of the data portable device 001 and the depth direction of the data storage device 101 coincide. .

  In FIG. 1, the longitudinal direction of the data storage device 101 is the X-axis direction, the depth direction is the Y-axis direction, and the height direction is the Z-axis direction.

  Further, in the data portable device 001, the memory card constituting the data storage unit 003a and the memory card constituting the data storage unit 003b overlap exactly when viewed from the Z-axis direction (in the X-axis direction and the Y-axis direction). It is assumed that it is inserted and mounted in the insertion slot so that the positions are equal and the positions in the Z-axis direction are different.

  The data storage device 101 includes a built-in HDD (Hard Disc Drive) constituting the data storage unit 106 and a touch panel constituting the display unit 104 and the operation unit 105.

  As shown in FIG. 4, in the posture 1 in which the data portable device 001 is mounted on the data storage device 101 so that the memory card constituting the data storage unit 003a is on the data storage device 101 side, the acceleration of the posture detection unit 004 The sensor measures the earth's gravitational acceleration + g, and on the other hand, the attitude 2 shown in FIG. 5 with the data portable device 001 turned upside down from the state of FIG. 4 (the memory card constituting the data storage unit 003b becomes the data storage device 101 side) Thus, in the attitude in which the portable data device 001 is mounted on the data storage device 101), the acceleration sensor of the attitude detection unit 004 measures the earth gravity acceleration −g.

  The posture detection unit 004 compares the detected earth gravity acceleration A with the relative relationship detection table T1 (FIG. 10) stored in the RAM 009, so that the relative posture between the data portable device 001 and the data storage device 101 is compared. Is detected. Specifically, when the detected earth gravity acceleration A is greater than or equal to value A1 and less than or equal to value A2, the attitude detection unit 004 detects that it is in the attitude 1 shown in FIG. When the earth gravity acceleration A is greater than or equal to the value A3 and less than or equal to the value A4, it is detected that the user is in the posture 2 shown in FIG.

  The storage unit identification unit 005 collates the relative attitude detected by the attitude detection unit 004 with the target identification table T2 (FIG. 11) stored in the RAM 009, and determines the data storage unit from which data is read out. Identify.

  Specifically, when the posture detection unit 004 detects posture 1, the storage unit identification unit 005 identifies the data storage unit 003a as a read destination, and when the posture detection unit 004 detects posture 2, the storage unit identification The unit 005 specifies the data storage unit 003b as a reading destination. Further, the storage unit specifying unit 005 sets a flag 1 in the specified destination area corresponding to the specified data storage unit, and sets a flag 0 in the specified destination area corresponding to the data storage unit not specified. Further, when the specified data storage unit is changed from the previously specified data storage unit, flag 1 is set in the change area corresponding to the selected data storage unit, and flag 0 is set in the other.

  The example of the target specifying table T2 shown in FIG. 11 indicates that the storage unit specifying unit 005 specifies the data storage unit 003a, and the data storage unit specified this time has been changed from the data storage unit specified last time. ing.

  Next, processing executed by the data portable device 001 will be described with reference to FIGS.

  The data portable device 001 repeatedly executes the data storage unit specifying process shown in FIG. 6 and FIG. 7 after the power is turned on, and the control unit 010 controls the proximity wireless communication unit 007 from the data storage device 101. It is determined whether a received data reception request command has been received (step S101). The data reception request command is a command for requesting the data storage device 101 to receive data transmitted by the data portable device 001.

  If it is determined that the data reception request command has been received (step S101; YES), the control unit 010 controls the close proximity wireless transfer unit 007 and transmits a data reception permission command to the data storage device 101 (step S102). ). The data reception permission command is a command for permitting the data storage device 101 to receive data transmitted by the data portable device 001.

  Subsequently, the control unit 010 controls the posture detection unit 004 to acquire information on the current posture of the data portable device 001 (hereinafter referred to as posture information), that is, a detection value of the gravitational acceleration sensor. Then, the acquired posture information is collated with the relative relationship detection table T1 stored in the RAM 009 to obtain the relative posture between the data portable device 001 and the data storage device 101 (step S103).

  Then, the control unit 010 controls the storage unit identification unit 005 to collate the relative attitude detected by the attitude detection unit 004 with the target identification table T2 stored in the RAM 009 and read out data to be transmitted. The original data storage unit is specified, and the value of the specification destination column of the target specification table T2 in the specified data storage unit is set to “1” (step S104).

  The control unit 010 reads data from the data storage unit 003a or 003b specified by the storage unit specifying unit 005 (step S105). The selection data generation unit 006 generates selection data based on the data read by the control unit 010 (step S106).

  The control unit 010 controls the close proximity wireless transfer unit 007 to transmit the selection data generated by the selection data generation unit 006 to the data storage device 101 (step S107).

  Next, the control unit 010 controls the attitude detection unit 004 to acquire the current attitude information of the data portable device 001 again, and the acquired attitude information is stored in the relative relationship detection table T1 stored in the RAM 009. Collation is performed to detect the relative posture of the data portable device 001 with respect to the data storage device 101 (step S108).

  Then, the control unit 010 refers to the identification destination column of the target identification table T2 stored in the RAM 009 and compares the relative attitude detected by the attitude detection unit 004 with the relative attitude detected last time. Thus, it is determined whether or not the attitude of the data portable device 001 detected this time has changed from the attitude of the data portable device 001 detected last time (step S109). When it is determined that the attitude of the portable data device 001 has changed (step S109; YES), the storage unit identification unit 005 identifies the relative attitude detected this time by the attitude detection unit 004 and stored in the RAM 009. The data storage unit 003a or 003b from which the data to be transmitted is read is re-identified by collating with the table T2, and the specification destination column and the change column of the target specification table T2 in the specified data storage unit 003a or 003b Is set to “1”, and the value of the specified destination column of the data storage unit specified last time is set to “0” (step S201).

  Then, the control unit 010 controls the close proximity wireless transfer unit 007 to transmit a selection image erasure instruction command to the data storage device 101 (step S202). Thereafter, the process returns to step S103, and the above-described process is repeated.

  On the other hand, when it is determined that the relative posture has not changed (step S109; NO), it is determined whether all the selection data has been transmitted (step S110).

  When it is determined that selection data that has not been transmitted remains (step S110; NO), the process returns to step S105, and the above-described process is repeated. On the other hand, if it is determined that all the selection data has been transmitted (step S110; YES), the control unit 010 controls the posture detection unit 004 to acquire the current posture information of the data portable device 001 again. The acquired posture information is collated with the relative relationship detection table T1 stored in the RAM 009, and the relative posture between the data portable device 001 and the data storage device 101 is detected (step S111).

  Then, the control unit 010 refers to the identification destination column of the target identification table T2 stored in the RAM 009, identifies the relative attitude detected last time, and previously detected the relative attitude detected this time. The relative attitude is compared, and it is determined whether or not the attitude of the data portable device 001 has changed (step S112).

  When it is determined that the relative posture of the data portable device 001 has changed (step S112; YES), the storage unit specifying unit 005 stores the relative posture detected by the posture detection unit 004 this time in the RAM 009. The data storage unit from which the data to be transmitted is read is re-specified by comparing with the target specifying table T2, and the values of the specification destination column and the change column of the target specifying table T2 in the specified data storage unit “1” is set, and the value of the specified destination column of the data storage unit specified last time is set to “0” (step S301).

  Then, the control unit 010 controls the close proximity wireless transfer unit 007 and transmits a selection image deletion instruction command to the data storage device 101 (step S302). Thereafter, the process returns to step S103, and the above-described process is repeated.

  On the other hand, when it is determined that the attitude of the data portable device 001 has not changed (step S112; NO), information related to the selection image selected by the user to instruct the data to be transmitted from the data portable device 001 (hereinafter, referred to as “posture”). It is determined whether or not (selected image information) has been received from the data storage device 101 (step S113).

  If it is determined that the selected image information has not been received (step S113; NO), the processing returns to step S111 and the above-described processing is repeated.

  On the other hand, if it is determined that the selected image information has been received (step S113; YES), information relating to the transmission mode of data transmitted by the user from the data portable device 001 (hereinafter referred to as transmission mode information) is transmitted from the data storage device 101. It is determined whether or not it has been received (step S114).

  If it is determined that the transmission mode information has not been received (step S114; NO), the process returns to step S111 and the above-described process is repeated. On the other hand, when it is determined that the transmission mode information has been received (step S114; YES), the control unit 010 determines the user from the identified data storage unit based on the selected image information transmitted from the data storage device 101. The selected data is read, the proximity wireless communication unit 007 is controlled, and the read data is transmitted (step S115).

  Then, based on the transmission mode information transmitted from the data storage device 101, the control unit 010 performs a necessary process on the data read in the process of step S115 (step S116). Specifically, when the transmission mode designated by the user is the copy mode, only the selected data reading process is performed, and when the transmission mode is the move mode, the selected data is erased.

  Then, the control unit 010 determines whether or not the user has instructed the end of the data reception process (step S117). Specifically, it is determined whether or not an instruction to end the data reception process has been received by determining whether or not an end instruction command transmitted from the data storage device 101 has been received when the user has issued an end instruction. To do. If there is no end instruction (step S117; NO), the process returns to step S101 and the above-described process is repeated. On the other hand, if it is determined that the end instruction has been issued (step S117; YES), the specification destination column and the change column of the target specification table T2 are initialized, and the data storage unit specifying process is ended.

  Next, processing executed by the data storage device 101 will be described with reference to FIGS.

  The control unit 109 of the data storage device 101 controls the close proximity wireless transfer unit 102, transmits a data reception request command to the data portable device 001, and starts a timer (not shown). (Step ST101). Then, control unit 109 controls proximity wireless communication unit 102 to determine whether or not a data reception permission command transmitted from data portable device 001 has been received (step ST102).

  When it is determined that the data reception permission command has not been received (step ST102; NO), the control unit 109 determines whether or not the timer has timed out (step ST201). If it is determined that the timer has not timed out (step ST201; NO), the process returns to step ST102 and the above-described process is repeated. On the other hand, if it is determined that the timer has timed out (step ST201; YES), the process returns to step ST101, the above process is repeated, and the reception of the data reception permission command transmitted from the data portable device 001 is awaited.

  On the other hand, when it is determined that the data reception permission command has been received (step ST102; YES), the control unit 109 controls the close proximity wireless communication unit 102 and receives selection data transmitted from the data portable device 001. If it is determined that the selection data has not been received (step ST103; NO), the process of step ST103 is repeated and the reception of the selection data is awaited.

  On the other hand, when it is determined that the selection data has been received (step ST103; YES), the control unit 109 controls the image generation unit 103 to generate a selection image based on the received selection data ( Step ST104). Then, control unit 109 controls display unit 104 to display the generated selection image on the display screen of display unit 104 (step ST105).

  Then, the control unit 109 determines whether or not the close proximity wireless communication unit 102 has received the selection image deletion instruction command (step ST106), and when it is determined that the selection image deletion instruction command has been received. (Step ST106; YES), the control unit 109 controls the display unit 104 to erase the selection image displayed on the display screen of the display unit 104 (step ST301). Thereafter, the process returns to step ST103, and the above-described process is repeated.

  Note that the processes in steps ST106 and ST301 are performed when the data portable device 001 is moved while the selection image is displayed on the display screen, and the data storage unit specified as the transmission data reading destination is changed. This process is necessary for the process and corresponds to the process in step S202 of FIG.

  Returning to FIG. 8, if it is determined that the selection image erasure instruction command has not been received (step ST106; NO), the control unit 109 determines whether or not all selection data has been received ( If it is determined in step ST107 that all the selection data has not been received (step ST107; NO), the process returns to step ST103, and the above process is repeated.

  On the other hand, when it is determined that all the selection data has been received (step ST107; YES), the control unit 109 displays the selection image information and transmission mode information input by the user operating the operation unit 105. Reception is started (step ST108).

  Then, the control unit 109 determines whether or not the close proximity wireless communication unit 102 has received the selection image deletion instruction command (step ST109), and when it is determined that the selection image deletion instruction command has been received. (Step ST109; YES), the control unit 109 controls the display unit 104, erases the selection image displayed on the display screen of the display unit 104, and ends the reception of the selection image information and the transmission mode information. (Step ST401). At this time, if the selection image information and the transmission mode information are already input, the information is deleted, and then the process returns to step ST103 to repeat the above-described process.

  The processes in steps ST109 and ST401 are performed when the data portable device 001 is moved while the user is selecting data to be transmitted, and the data storage unit specified as the transmission data reading destination is changed. This is a necessary process and corresponds to the process of step S302 in FIG.

  Returning to FIG. 8, when it is determined that the selection image deletion instruction command has not been received (step ST109; NO), the control unit 109 determines whether the selection image information and the transmission mode information are input. If it is determined (step ST110) and it is determined that the selection image information and the transmission mode information are not input (step ST110; NO), the process returns to step ST109 and the above-described process is repeated. On the other hand, when it is determined that the selection image information and the transmission mode information are input (step ST110; YES), the control unit 109 controls the proximity wireless communication unit 102, and the input selection image information is transmitted to the data portable device. It transmits to 001 (step ST111), and further transmits the input transmission mode information to the data portable device 001 (step ST112).

  Then, based on the selected image information, the control unit 109 determines whether or not the proximity wireless communication unit 102 has received the data transmitted from the data portable device 001 (step ST113). If it is determined that data has not been received (step ST113; NO), the process of step ST113 is repeated to wait for data to be received.

  On the other hand, when it is determined that data has been received (step ST113; YES), the control unit 109 stores the received data in the data storage unit 106 (step ST114). Then, based on the selected image information, control unit 109 determines whether proximity wireless communication unit 102 has received all data (step ST115). If it is determined that all data has not been received (step ST115; NO), the process returns to step ST113 and the above-described process is repeated.

  On the other hand, when it is determined that all data has been received (step ST115; YES), the control unit 109 determines whether or not an instruction to end the data reception process has been issued by the user (step ST116). Here, the end instruction of the data reception process indicates, for example, a case where there is an input for instructing the end of the reception process from the operation unit 105.

  If it is determined that the end instruction has not been given (step ST116; NO), the process returns to step ST101 and the above-described process is repeated. On the other hand, if it is determined that an end instruction has been issued (step ST116; YES), the control unit 109 generates an end instruction command if the end instruction is instructed from the operation unit 105, for example, and ends the instruction. The command is transmitted to the data portable device 001, and the data reception process is terminated.

  With this configuration, for example, if the user instructs data transfer in the state shown in FIG. 1, the data portable device 001 is determined as posture 2 based on the measurement of the acceleration sensor (step S <b> 103). ), The data storage unit 003b corresponding to the posture 2 is specified (step S104), the data is sequentially read from the specified data storage unit 003b (step S105), and the data for selection is generated (step S106). It is transmitted to the apparatus 101 (step S107).

  On the other hand, the data storage device 101 sequentially receives the transmitted selection data (step ST103), generates a selection image, and displays it (steps ST104 and 105).

  Here, when the user designates an arbitrary selection image and transmission mode (copy or move) from the displayed selection images (step ST110; YES), these pieces of information are transmitted to the data portable device 001. (Steps ST111 and ST112).

  The data portable device 001 receives the transmitted selection image information and transmission mode (steps S113 and S114), reads and transmits the selected data (step S115), and the designated transmission mode is move. The corresponding data is deleted (step S116).

  The data storage device 101 sequentially receives the data transmitted from the data portable device 001 (step ST113; YES) and stores it (step ST114).

  Thus, if, on the other hand, the user notices that he or she has selected the data storage unit by mistake, for example, when the desired image does not exist in the displayed selection image, the user carries the data The posture (front and back) of the device 001 is changed. Thereby, it is detected in steps S109 and S112 that the posture has changed, and an erasure instruction command is transmitted to the data storage device 101 (S202, S302), and the selection data displayed on the display unit of the data storage device 101 Is deleted (steps ST301 and ST401). Thereafter, processing corresponding to the changed posture is performed.

  As described above, according to the present embodiment, a data storage device to be accessed is selected from a plurality of data storage units by a simple operation of switching the mounting posture (front and back) of the data portable device 001. Intuitive operation is possible.

  In the above description, in order to facilitate understanding, an example in which data is transmitted from the selected data storage unit 003a or 003b of the data portable device 001 to the data storage device 101 has been described. Applicable when transmitting data stored in the data storage device 101 to the storage unit 003a or 003b, or when editing or processing the stored data by accessing the data storage unit 003a or 003b of the data portable device 001 It is.

The radio wave transmitted from the transmission unit 012 of the data portable device 001 can be received by the reception unit 110 of the data storage device 101, and the radio wave transmitted from the transmission unit 111 of the data storage device 101 is received by the data portable device 001. Can be received by the receiving unit 011.

  Here, with reference to FIG. 14 and FIG. 15, the posture detection unit 004 measures the relative strength of the data portable device 001 with respect to the data storage device 101 by measuring the intensity of the radio wave received by the reception unit 011. It will be described with reference to an example how the data storage unit is specified based on the detected relative attitude. In the present embodiment, it is assumed that the position where the portable data device 001 is mounted on the data storage device 101 is determined in advance.

  FIG. 14 is a front view of the data portable device 001 placed so that the data storage unit 003a is closer to the data storage device 101 than the data storage unit 003b. On the other hand, FIG. 15 turns the data portable device 001 upside down from the state of the data portable device 001 in FIG. 14, and places the data portable device 001 so that the data storage unit 003b is closer to the data storage device 101 side than the data storage unit 003a. It is the figure seen from the front in a state.

  The receiving unit 011 and the transmitting unit 012 of the data portable device 001 are arranged so that the Y coordinate and the Z coordinate are equal and only the X coordinate is different. Similarly, the reception unit 110 and the transmission unit 111 of the data storage device 101 are arranged so that the Y coordinate and the Z coordinate are equal and only the X coordinate is different.

  In the attitude of the data portable device 001 in FIG. 14 (the data storage unit 003a is on the data storage device 101 side), the distance between the receiving unit 011 of the data portable device 001 and the transmission unit 111 of the data storage device 101 is the data portable device in FIG. Since it is far from the posture of 001 (the data storage unit 003b is on the data storage device 101 side), the intensity of the radio wave received by the receiving unit 011 is smaller in the state of the data portable device 001 in FIG.

  In this way, the attitude detection unit 004 measures the intensity of the radio wave received by the reception unit 011 and compares the measured received radio wave intensity with the relative relationship detection table T1 (FIG. 16) stored in the RAM 009. The relative attitude of the data portable device 001 with respect to the data storage device 101 (in this embodiment, which of the data storage units 003a and 003b is on the data storage device 101 side) is detected.

Hereinafter, in this embodiment, the relative relationship detection unit 203 measures the intensity of radio waves transmitted from the data portable device 001 (each receiving unit and each transmitting unit are not shown), and detects a relative posture. Will be described.

  The communication unit identification unit 204 collates the relative attitude of the data portable device 001 detected by the relative relationship detection unit 203 with respect to the connection destination identification device 201 with the target identification table T2 (FIG. 37) stored in the RAM 108. The communication unit 203a or the communication unit 203b is used to specify which communication is performed.

  With the above configuration, it is possible to select an external communication device (not shown) as a communication connection destination of the data portable device 001 by detecting a relative posture or the like of the data portable device 001 with respect to the connection destination specifying device 201. It becomes. Note that, similarly to the arrangement of the memory card insertion slot in the first to fourth embodiments, depending on the detection method of the relative relationship (relative posture, position, orientation) of the data portable device 001 to the connection destination specifying device 201. Thus, each communication unit may be arranged so that the user can imagine which communication unit is specified by the communication unit specifying unit 204.

  Next, with reference to FIG. 35, the connection destination specifying process of the connection destination specifying device 201 in the present embodiment will be described. In the present embodiment, it is assumed that the user displays the selection image on the display screen of the display unit 017 of the data portable device 001 in advance.

  The control unit 109 of the connection destination specifying device 201 controls the close proximity wireless transfer unit 102 to determine whether or not a data transmission request command transmitted from the data portable device 001 has been received (step S501). Here, the data transmission request command is a command for requesting that the data portable device 001 transmits data to the connection destination specifying device 201.

  If it is determined that the data transmission request command has not been received (step S501; NO), the process returns to step S501 to wait for reception of the data transmission request command.

  On the other hand, when a data transmission request command is received (step S501; YES), the control unit 109 controls the close proximity wireless transfer unit 102 and transmits a data transmission permission command (step S502). Here, the data transmission permission command is a command for permitting transmission of data from the data portable device 001 to the connection destination specifying device 201.

  The control unit 109 controls the relative relationship detection unit 203 to measure the received radio wave intensity, and compares the measured received radio wave intensity with the relative relationship detection table T1 (FIG. 16) stored in the RAM 108 to obtain data. A relative posture of the portable device 001 with respect to the connection destination specifying device 201 is detected (step S503). The communication unit identification unit 204 collates the detected relative posture with the target identification table T2 (FIG. 37) stored in the RAM 108, and performs communication using either the communication unit 202a or the communication unit 202b. In addition to specifying whether or not to perform, the value of the specifying destination column of the target specifying table T2 in the specified communication unit is set to “1” (step S504). And the control part 109 establishes communication with the external communication apparatus connected to the identified communication part (step S505).

  Then, the control unit 109 controls the relative relationship detection unit 203 to measure the received radio wave intensity, and compares the measured received radio wave intensity with the relative relationship detection table T1 (FIG. 16) stored in the RAM 108. The relative attitude of the data portable device 001 with respect to the connection destination specifying device 201 is detected (step S506).

  Then, the control unit 109 refers to the identification destination column of the target identification table T2 (FIG. 37) stored in the RAM 108, identifies the relative posture detected last time, and determines the relative position detected this time. It is determined whether or not the relative posture of the data portable device 001 has changed by comparing the posture and the previously detected relative posture (step S507). When it is determined that the attitude of the portable data device 001 has changed (step S507; YES), the communication unit identification unit 204 stores the relative attitude detected this time in the RAM 108. T2 (FIG. 37) is collated, and the communication unit is specified again, and the values of the specification destination column and the change column of the target specification table T2 in the specified communication unit are set to “1”, and the communication specified last time The value of the specific destination column of the copy is set to “0” (step S601).

  Then, the control unit 109 disconnects the communication established with the external communication device connected to the communication unit specified last time, and communicates with the external communication device connected to the communication unit specified this time. Communication is established (step S602), the process returns to step S506, and the above-described process is repeated.

  On the other hand, when it is determined that the attitude of the data portable device 001 has not changed (step S507; NO), the control unit 109 controls the proximity wireless communication unit 102 and is transmitted from the data portable device 001. It is determined whether or not data has been received (step S508). If it is determined that the data transmitted from the data portable device 001 has not been received (step S508; NO), the process returns to step S506 and the above-described process is repeated.

  On the other hand, when it is determined that the data transmitted from the data portable device 001 is received (step S508; YES), the control unit 109 of the connection destination specifying device 201 uses the data received by the close proximity wireless communication unit 102 as It transmits to an external communication apparatus (not shown) via the communication part specified by the communication part specification part 204 (step S509). At this time, if the format of the data transmitted from the data portable device 001 is different from the format of the data requested by the external communication device (not shown), the control unit 109 also performs a data format conversion process.

  Then, the control unit 109 determines whether or not the user has instructed the end of the data transmission process (step S510). Specifically, it is determined whether or not an instruction to end the data transmission process has been received by determining whether or not an end instruction command transmitted from the data portable device 001 has been received when an end instruction is issued by the user. To do. If it is determined that there is no termination instruction (step S510; NO), the process returns to step S501 and the above-described process is repeated. On the other hand, if it is determined that an end instruction has been issued (step S510; YES), the specification destination column and the change column of the target specification table T2 are initialized, and the connection destination specification processing ends.

  Next, with reference to FIG. 36, a data transmission process on the data portable device 001 side will be described. In the present embodiment, it is assumed that the user displays the selection image on the display screen of the display unit 017 of the data portable device 001 in advance.

  The control unit 010 controls the close proximity wireless transfer unit 007 to transmit a data transmission request command to the connection destination specifying device 201 and start a timer (not shown) (step ST501). Then, control unit 010 controls proximity wireless communication unit 007 to determine whether or not a data transmission permission command transmitted from connection destination specifying device 201 has been received (step ST502).

  When it is determined that the data transmission permission command has not been received (step ST502; NO), the control unit 010 determines whether or not the timer has timed out (step ST601). If it is determined that the timer has not timed out (step ST601; NO), the process returns to step ST502 and the above-described process is repeated. On the other hand, when it is determined that the timer has timed out (step ST601; YES), the processing returns to step ST501 and the above-described processing is repeated.

  On the other hand, when it is determined that the data transmission permission command has been received (step ST502; YES), the control unit 010 accepts selection image information and transmission mode information that are input when the user operates the operation unit 015. Is started (step ST503).

  Then, control section 010 determines whether selection image information and transmission mode information have been input (step ST504). If it is determined that selection image information and transmission mode information have not been input (step ST504). (ST504; NO), the process of step ST504 is repeated, and the input of selection image information and transmission mode information is awaited. On the other hand, when it is determined that the selection image information and the transmission mode information are input (step ST504; YES), the control unit 010 reads data from the data storage unit 003a based on the selected image information, and performs proximity wireless communication. Data is transmitted to the connection destination specifying apparatus 201 via the communication unit 007 (step ST505).

  Then, control section 010 determines whether or not the selection image information and transmission mode information are additionally input (step ST506). If it is determined that the selection image information and transmission mode information are additionally input (step ST506; YES), the process of step ST505 is performed. Return to and repeat the above process. On the other hand, when it is determined that no additional input has been made (step ST506; NO), the control unit 010 performs a necessary process on the data read in the process of step ST505 based on the transmission mode information (step ST506). ST507). Specifically, when the transmission mode designated by the user is the copy mode, only the selected data reading process is performed, and when the transmission mode is the move mode, the selected data is erased.

  Then, control section 010 determines whether or not the user has instructed to end the data reception process (step ST508). Here, the end instruction of the data transmission process indicates, for example, a case where there is an input for instructing the end of the data transmission process from the operation unit 015.

  If it is determined that the end instruction has not been given (step ST508; NO), the process returns to step ST501 and the above-described process is repeated. On the other hand, if it is determined that an end instruction has been issued (step ST508; YES), the control unit 010 generates an end instruction command if the end instruction is instructed from the operation unit 015, for example. An end instruction command is transmitted to the connection destination specifying apparatus 201 via the wireless communication unit 007, and the data transmission process is ended.

  According to the first to fourth embodiments, the relative relationship (relative posture, position, orientation) of the data portable device 001 with respect to the data storage device 101 is detected, and transmission is performed based on the detected relative relationship.
