Subsequently, when the open / close detection unit 28 detects that the terminal body is closed (S605), it is checked whether or not FLAG = 1 (S619). As a result of S619, when it is confirmed that FLAG = 1, the internal and external keys are locked (S621), and the process proceeds to process B. That is, the process returns to the process of FIG. 5 (S503). As a result of S619, when it is not confirmed that FLAG = 1, the process directly proceeds to process B.
[0024]
On the other hand, if the open / close detection unit 28 has not detected the closed state in S605, it is confirmed whether or not a key input has been made (S607). As a result, if a key is input, it is confirmed whether or not the side key 203 has been pressed long (S609). If no key is input as a result of S607, the process returns to pre-processing (S605).
If the side key 203 is pressed for a long time in S609, it is confirmed whether or not FLAG = 1 (S611). If FLAG = 1, FLAG = 0 is set (S617). On the other hand, if the result of S611 is not FLAG = 1, FLAG = 1 is set (S615).
If the side key 203 is not pressed for a long time in S609, processing corresponding to the key operation is performed (S613).
When the flag value setting (S615, S617) or the process according to the key operation (S613) is completed, the process returns to the previous determination process (S605).
