<Operation>
(Part 1)
The operation when the electronic data of the large display 24 is received by the stylus pen 22 by optical communication and stored in the memory 88 will be described using the flowcharts shown in FIGS.

  With reference to FIG. 7, first, the control unit 80 of the stylus pen 22 determines whether or not the stylus pen 22 is in a locked state (step S100). Control branches according to the determination result.

  If the stylus pen 22 is not in the locked state, the control unit 80 advances the control to step S102. On the other hand, when the stylus pen 22 is in the locked state, the control unit 80 waits for a long press operation of the media mode button 90 to release the locked state of the stylus pen 22 (steps S126 and S128), and then performs control. Advances to step S102.

  When the control proceeds to step S102, the control unit 80 waits for the media mode button 90 to be turned on. When the media mode button 90 is turned on, the stylus pen 22 functions as a recording medium. Therefore, in order to allow the user to check the free space of the memory 88, the lamp of the data indicator 104 is turned on to display the memory capacity. This is performed (step S104). At this time, if the memory 88 has no capacity, that is, there is no free capacity, all the lamps of the data indicator 104 are lit in red and a message to that effect is displayed, and the memory 88 has sufficient capacity. If there is, the number of lamps smaller than the maximum number of lamps of the data indicator 104 is turned on and a message to that effect is displayed. Thereafter, the control unit 80 advances the control to step S106.

  When the control proceeds to step S106, the control unit 80 determines whether or not the memory 88 has an empty capacity. Control branches according to the determination result.

  If the capacity of the memory 88 is not sufficient (YES in step S106), as described above, all the lamps of the data indicator 104 are turned on and a so-called full display is made. A message indicating that the electronic data cannot be displayed is displayed on the display panel 106, and a message is displayed on the display panel 106 as to whether or not the already received electronic data is compressed and stored again (step S130). Thereafter, when the user selects “NO” on the display panel 106 with the arrow keys 100 and 102 because the compression is unnecessary (NO in step S132), the control unit 80 interrupts the process (step S134). If “YES” on display panel 106 has been selected by the user using arrow keys 100 and 102 (YES in step S132), control is returned to step S106.

  If the memory 88 has free space (YES in step S106), the electronic data to be stored in the built-in memory 88 of the stylus pen 22 among the electronic data displayed on the large display 24 using the stylus pen 22 is the pen body 120. It waits for selection by clicking (Step S110).

  When the click selection operation by the stylus pen 22 is performed to store the electronic data in the memory 88, the control unit 80 waits for the data-in button 92 to be operated in this state (step S112).

  When the data-in button 92 is operated, the control unit 80 executes control from steps S114 to S124. Specifically, when the data-in button 92 is pressed, data transmission by optical communication of electronic data stored in the network computer 28 or the large display-attached computer 26 starts. During data transmission, it is checked again whether or not the memory 88 has enough capacity to store electronic data. If the memory 88 has enough capacity, reception of electronic data via the optical terminal 108 starts. . At this time, if the file name of the received electronic data is the same as the file name of the already received electronic data, a message as to whether or not to overwrite is displayed on the display panel 106, and it is selected not to overwrite. Then, a serial number is added to the file name of the newly received electronic data and automatically renamed to continue reception. When there is no mistake in the selected electronic data and the reception of the electronic data is continued, the electronic data is received as it is, and the electronic data is stored in the built-in memory 88 of the stylus pen 22.

  When it is desired to stop the reception of electronic data halfway, such as when the electronic data is selected by mistake, the user presses the cancel button 96, but the control unit 80 operates the cancel button 96 in step S122. It is determined whether or not.

  When the cancel button 96 is operated, the control unit 80 controls steps S200 to S204 shown in FIG.

  Referring to FIG. 8, control unit 80 causes display panel 106 to display a message to cancel reception of electronic data (step S200), blocks reception of electronic data (step S202), and controls stylus pen 22 to The electronic data stored halfway in the built-in memory 88 is deleted (step S204).

  In step S116 shown in FIG. 7, if the memory 88 is insufficient, the control unit 80 executes the control in steps S130 to S134 described above.

  When the user performs a click operation to select desired electronic data from the various electronic data displayed on the large display 24 using the pen body 120 of the stylus pen 22, the selected electronic data is selected. Are received from the large display 24 in the order of selection and stored in the built-in memory 88 of the stylus pen 22.

(Part 2)
The operation when the electronic data stored in the built-in memory 88 of the stylus pen 22 is transmitted to the large display 24 and stored will be described using the flowchart shown in FIG.

  Referring to FIG. 9, first, control unit 80 of stylus pen 22 determines whether or not stylus pen 22 is in a locked state (step S300). When the stylus pen 22 is not in the locked state, the control unit 80 advances the control to steps S302 and S304. On the other hand, when the stylus pen 22 is in the locked state, the control unit 80 waits for the long press operation of the media mode button 90 to release the locked state of the stylus pen 22 (steps S316 and S318), and then performs control. Advances to steps S302 and S304.

  When the control proceeds to steps S302 and S304, the control unit 80 waits for the media mode button 90 and the memory display button 98 to be turned ON in this order. When the media mode button 90 and the memory display button 98 are sequentially operated, the control unit 80 executes the control of steps S306 to S312.

  Specifically, the control unit 80 displays the file names of the electronic data stored in the built-in memory 88 of the stylus pen 22 on the display panel 106 in the order of alphabets, Japanese syllabary, numbers, serial numbers (serial numbers), and the like. indicate. When the user confirms the displayed file name and operates the data out button in a state where the file name of the electronic data to be moved is selected using the arrow keys 100 and 102, the control unit 80 causes the stylus pen 22 to operate. Among the electronic data stored in the built-in memory 88, the electronic data selected in step S308 is started to be transmitted by optical communication toward the large display 24 which is substantially the desktop of the attached computer 26. The transmitted electronic data is transferred to the large display 24 via the optical terminal 40. When the selected electronic data is correct and the transmission of the electronic data is continued, the control unit 80 transmits the electronic data as it is. The transmitted electronic data is stored in the storage unit 54 of the large display-attached computer 26 that is RGB-connected to the large display 24.

  When it is desired to stop the transmission of electronic data halfway, such as when electronic data is selected by mistake in step S314, the cancel button 96 is operated, but the control unit 80 operates the cancel button 96. Then, a message to cancel transmission of electronic data is displayed on the display panel 106 (step S320), and the process is interrupted (step S322).

(Part 3)
Using the flowchart shown in FIG. 10, the stylus pen 22 is connected to the large display-attached computer 26 or the network computer 28 via USB, and the electronic data stored in the built-in memory 88 of the stylus pen 22 is moved and unnecessary. The operation when deleting electronic data will be described.

  Referring to FIG. 10, first, control unit 80 of stylus pen 22 determines whether or not stylus pen 22 is in a locked state (step S400). If the stylus pen 22 is not in a locked state, control is directly performed in step S402. If the stylus pen 22 is in the locked state, the locked state is released after the long press operation of the media mode button 90 (steps S316 and S318), and the control proceeds to step S402.

  When the control proceeds to step S402, the control unit 80 waits for the USB terminal 110 of the stylus pen 22 to be plugged into the USB port 64 of the large display-attached computer 26 or the USB port 78 of the network computer 28. When the USB connection between the stylus pen 22 and the large display-attached computer 26 or the network computer 28 is established, the control unit 80 executes the control in steps S404 to S418.

  Specifically, the stylus pen 22 is recognized as a removable disk of the computer by the USB connection between the stylus pen 22 and the large display-attached computer 26 or the network computer 28, and the stylus pen 22 is connected to the monitor or the large display 24 of the network computer 28. The electronic data stored in the internal memory 88 and the directory structure are displayed.

  In step S404, if the electronic data is to be moved to a place other than the large display 24 which is the desktop of the large display-attached computer 26 because the capacity of the built-in memory 88 of the stylus pen 22 is sufficient, the displayed electronic data is transferred to the mouse. Select using a pointing device, etc., and move to the desired storage location.

  On the other hand, in step S404, when it is desired to delete unnecessary electronic data because the capacity of the built-in memory 88 of the stylus pen 22 is not sufficient, the control unit 80 displays the file name of the electronic data stored in the memory 88. A list is displayed on the panel 106 (step S410). At the same time, a message is displayed on the display panel 106 as to whether or not electronic data to be deleted is designated in advance from the electronic data displayed in the list. When electronic data is designated in advance, if the electronic data to be deleted is selected with the arrow keys 100 and 102, the selected deletion file name is stored in the deletion file name list storage area 88A in the memory 88. Therefore, in step S414, it is possible to delete only the electronic data specified in step S412. On the other hand, if the electronic data to be deleted is not designated in advance, in steps S416 and S418, the user arbitrarily selects the data to be deleted from the electronic data displayed on the display panel 106 with the arrow keys. delete.
