no. 1 Embodiment approach 》
[0058] In the present embodiment, as an example of the case where the present invention is implemented, a car A and an electronic key 2 that are paired, such as figure 1 Electronic key system shown. There are many pairs of the car A and the electronic key 2, but this embodiment takes one pair as an example.
[0059] The automobile A includes a program execution device 1 and an engine 3 . In the present embodiment, the engine 3 is started via the program execution device 1 by operating the electronic key 2 . The electronic key 2 is paired with the program execution device 1 mounted on the car A that is paired with the electronic key 2 .
[0060] In addition, the electronic key 2 in this embodiment is as figure 1 The shown shape simulates a classic key shape, but the electronic key 2 may be in other suitable shapes such as a card shape as long as it has a hardware structure described later.
[0061] figure 2 The hardware configurations of the program execution device 1 and...

[0089] Figure 6 An electronic key system according to Modification 1 is shown.
[0090] Such as Figure 6 As shown, the electronic key system of Modification 1 has the same configuration as that of the electronic key system of the first embodiment.
[0091] The electronic key system of Modification 1 differs from the electronic key system of the first embodiment in that the program execution device 1 of the electronic key system of Modification 1 is as follows: Figure 6 As shown, an interface 18 is provided.
[0092] Interface 18 is connected to bus 16 . In addition, the interface 18 is connected to the external ROM 4 by a cable in this embodiment, but it may be wireless. The external ROM 4 is fixed at a predetermined position among components constituting the automobile A. As shown in FIG. The parts to which the external ROM 4 is fixed are appropriately determined from the parts constituting the automobile A in consideration of the importance of functionality, the impo...

[0099] Figure 7 An electronic key system according to Modification 2 is shown.
[0100] Such as Figure 7 As shown, the electronic key system of Modification 2 has the same configuration as that of the electronic key system of the first embodiment.
[0101] The electronic key system of Modification 2 differs from the electronic key system of the first embodiment in that the program execution device 1 of the electronic key system of Modification 2 is as follows: Figure 7 As shown, an imaging unit 19 is provided.
[0102] The imaging unit 19 can read component information whose information can be read by image recognition. The imaging unit 19 is connected to the bus 16 . The imaging unit 19 is a barcode reader in the second modification, and the component information is a barcode in the second modification. The barcode 1 is printed irremovably on predetermined parts among the parts constituting the automobile A. As shown in FIG. The part on which the barcode is printed is ...
