If the data in the memory card 35 of the image display device 1 is not the latest, new data stored in the memory card 58 of the charging device 50 is written. Then, as shown in FIG. 7, when the movable shaft 191 of the actuator 91 is extended, the slider 100 moves to the right (in FIG. 7), and the guide pins 104 are inserted into the guide grooves 120 and 121 of the slider 100. , 105 are guided, the guide pins 104, 105 are raised, the movable cradle 171 is lifted, and the image display device 1 is raised to a pop-up state. This state is the protruding position. The structure and operation of the charging units 72, 73, 74, 75, 76 are the same as those of the charging unit 71.

  Next, the first embodiment of the operation of the charging device 50 will be described with reference to FIGS. In the following example, a case where the image display device 1 is inserted into the charging unit 71 of the charging device 50 to perform charging and data rewriting will be described, but the same applies to the other charging units 72 to 76. The control program of the flowchart shown in FIG. 9 is stored in the ROM 54 of the charging device 50 and is executed by the CPU 51. In the charging device 50, when the image display device 1 is not inserted into the movable cradle 171, the movable cradle 171 rises and is positioned at the protruding position, waiting for insertion of the image display device 1 (S 1: NO). As shown in FIG. 7, when the user inserts the image display device 1 into the movable cradle 171, the USB connector 32 of the image display device 1 shown in FIG. 6 is fitted into the terminal connection terminal 81 of the charging device 50. In this state, since the image display device 1 is electrically connected to the terminal data input / output controller 62 of the charging device 50, the CPU 51 can detect that the image display device 1 is inserted into the movable cradle 171 and connected thereto. (S1: YES).

  Next, the CPU 51 determines whether or not the document data 300 of the memory card 35 of the image display device 1 inserted and connected to the movable cradle 171 is the latest via the terminal data input / output controller 62 (S2). This determination is based on whether the date of the document information 302 of the document data 300 of the memory card 35 of the image display device 1 is the same as the date of the document information 302 of the same document data 300 stored in the memory card 58 of the charging device 50. Judge. Since the latest data is always stored in the memory card 58 of the charging device 50, when the dates do not match, it is determined that the document information 302 of the document data 300 of the memory card 35 of the image display device 1 is not the latest. (S2: NO).

  When it is determined in the determination process of S2 that the document information 302 of the document data 300 of the memory card 35 of the image display device 1 is not the latest (S2: NO), the CPU 51 passes the actuator 91 via the pop-up storage controller 60. The movable shaft 191 is housed and the movable cradle 171 is lowered and moved to the storage position as shown in FIG. 5 (S3). Next, the CPU 51 rewrites the document data 300 of the memory card 35 of the image display device 1 to the latest data stored in the memory card 58 of the charging device 50 via the terminal data input / output controller 62 (S4).

  When the document data 300 in the memory card 35 of the image display device 1 is the latest data or when the document data 300 becomes the latest data by rewriting (S2: YES), the CPU 51 determines that the voltage of the battery 31 of the image display device 1 is in advance. It is determined through the power supply unit 63 whether or not the voltage is equal to or higher than the set value (S5). When the voltage of the battery 31 is not equal to or higher than the set value voltage (S5: NO), charging is necessary. Therefore, the CPU 51 accommodates the movable shaft 191 of the actuator 91 via the pop-up storage controller 60, as shown in FIG. As shown, the movable cradle 171 is lowered and moved to the storage position, and charging is started (S6). This charging is performed by the CPU 51 controlling the power supply unit 63. In the process of S3, when the movable cradle 171 is in the lowered state, the state in which the movable cradle 171 is lowered is maintained and charging is started (S6).

  Next, when the voltage of the battery 31 is equal to or higher than the set value voltage from the beginning and when the voltage becomes equal to or higher than the set value voltage due to charging (S5: YES), the CPU 51 moves the movable shaft 191 of the actuator 91 via the pop-up storage controller 60. As shown in FIG. 7, the movable cradle 171 is raised and moved to the protruding position (S7). Therefore, when the document data 300 of the memory card 35 of the image display device 1 is the latest (S2: YES) and the voltage of the battery 31 is equal to or higher than the set value and charging is completed (S5: YES), the image display is performed. As shown in FIG. 7, the device 1 is positioned in the protruding position to be in a pop-up state and can be easily taken out. In addition, it can be seen that the data is the latest and charging is completed at a glance.

  Next, a second embodiment of the operation of the charging device 50 will be described with reference to FIGS. 6 to 8, 10, 11, and 12. In the following example, a case where the image display device 1 is inserted into the charging unit 71 of the charging device 50 to perform charging and data rewriting will be described, but the same applies to the other charging units 72 to 76. A control program of the flowchart shown in FIG. 10 is stored in the ROM 54 of the charging device 50 and is executed by the CPU 51. In the charging device 50, when the image display device 1 is not inserted into the movable cradle 171, the movable cradle 171 rises and is positioned at the protruding position, waiting for insertion of the image display device 1 (S 11: NO). As shown in FIG. 7, when the user inserts the image display device 1 into the movable cradle 171, the USB connector 32 of the image display device 1 shown in FIG. 6 is fitted into the terminal connection terminal 81 of the charging device 50. In this state, since the image display device 1 is electrically connected to the terminal data input / output controller 62 of the charging device 50, the CPU 51 can detect that the image display device 1 is inserted into the movable cradle 171 and connected thereto. (S11: YES).

  Next, the CPU 51 determines whether or not the document data 300 of the memory card 35 of the image display device 1 inserted and connected to the movable cradle 171 is the latest via the terminal data input / output controller 62 (S12). This determination is based on whether the date of the document information 302 of the document data 300 of the memory card 35 of the image display device 1 is the same as the date of the document information 302 of the same document data 300 stored in the memory card 58 of the charging device 50. Judge. Since the latest data is always stored in the memory card 58 of the charging device 50, when the dates do not match, it is determined that the document information 302 of the document data 300 of the memory card 35 of the image display device 1 is not the latest. (S12: NO).

  When it is determined in the determination process of S12 that the document information 302 of the document data 300 of the memory card 35 of the image display device 1 is not the latest (S12: NO), the CPU 51 passes the actuator 91 via the pop-up storage controller 60. The movable shaft 191 is stored, and the movable cradle 171 is lowered and moved to the storage position as shown in FIG. 5 (S13). Next, the CPU 51 rewrites the document data 300 of the memory card 35 of the image display device 1 to the latest data stored in the memory card 58 of the charging device 50 via the terminal data input / output controller 62 (S14).

  When the document data 300 of the memory card 35 of the image display device 1 is the latest data or when the document data 300 becomes the latest data by rewriting (S12: YES), the CPU 51 determines that the voltage of the battery 31 of the image display device 1 is in advance. It is determined via the power supply unit 63 whether or not the voltage is equal to or higher than the set value (S15). When the voltage of the battery 31 is not equal to or higher than the set voltage (S15: NO), charging is necessary. Therefore, the CPU 51 accommodates the movable shaft 191 of the actuator 91 via the pop-up storage controller 60, as shown in FIG. As shown, the movable cradle 171 is lowered and moved to the storage position, and charging is started (S16). This charging is performed by the CPU 51 controlling the power supply unit 63. In the process of S13, when the movable cradle 171 is in the lowered state, the lowered state of the movable cradle 171 is maintained as it is, and charging is started (S16).

  Next, when the voltage of the battery 31 is equal to or higher than the set value from the beginning and when the voltage becomes equal to or higher than the set value due to charging (S15: YES), the movable cradle of the adjacent charging unit holds the image display device 1. It is then determined whether or not it is popped up (S17). The determination in S17 is, for example, that the movable cradle 172 of the charging unit 72 adjacent to the charging unit 71 holds the image display device 1 (with the USB connector 32 electrically connected to the terminal connection terminal 81). It is then determined whether or not it is in the protruding position. Specifically, whether or not the pop-up storage controller 60 is controlled so that the operating shaft of the actuator that drives the movable cradle 172 of the charging unit 72 protrudes, and the USB connector 32 of the image display device 1 is connected to the movable cradle 172. The CPU 51 determines whether the terminal connection terminal 82 is electrically connected. Here, when the movable cradle 172 of the charging unit 72 adjacent to the charging unit 71 is raised while holding the image display device 1 (S17: YES), the movable cradle 171 of the charging unit 71 is also raised. Then, it becomes difficult to take out the image display device 1 held by the movable cradle 171.

  Therefore, the movable cradle 171 of the charging unit 71 is lowered and placed in the retracted position (S18), and waits until the movable cradle 172 of the charging unit 72 is lowered and the image display device 1 held on the movable cradle 171 is easy to remove. (S12: YES, S15: YES, S17). Here, when the movable cradle 172 of the charging unit 72 is lowered (S17: NO), the image display device 1 held on the movable cradle 171 can be easily taken up, so that the CPU 51 passes through the pop-up storage controller 60. Then, the movable shaft 191 of the actuator 91 is protruded, and the movable cradle 171 is raised and moved to the protruding position as shown in FIG. 7 (S19). Therefore, as shown in FIG. 12, the image display device 1 held by the movable cradle 171 of the charging unit 71 can be easily taken out. Even when the image display apparatus 1 is detached from the movable cradle 172 of the charging unit 72, the CPU 51 projects the movable shaft 191 of the actuator 91 via the pop-up storage controller 60, as shown in FIG. Is moved to the protruding position (S19).

  In the second embodiment, the determination of the pop-up state of the movable cradle holding the image display device 1 close to the image display device 1 being charged (S17) is the image display device 1 (movable Only one side of the cradle 171) may be targeted, or both sides may be targeted. In addition, a plurality of objects may be targeted for the determination of the pop-up state of the movable cradle holding the image display device 1 in proximity to the image display device 1 being charged (S17). For example, if the two movable cradles 172 and 173 (see FIG. 4) adjacent to the movable cradle 171 holding the image display device 1 being charged are not lowered, the determination of S17 is made. It may not be set to NO. In this case, since the two adjacent movable cradles 172 and 173 are lowered and are in the storage position, the image display device 1 held by the movable cradle 171 of the charging unit 71 can be easily taken out. Alternatively, it may be determined whether three or four adjacent objects are descending.

  In addition, this invention is not limited to the said embodiment, A various change is possible. For example, the number of charging units may be any number such as two, three, four, and five. In the first and second embodiments described above, the latest determination is made on the data (S2 and S12), but this determination is stopped and only the determination of the state of charge of the battery (S5 and S15) is made. good.
