  When the lock state is the lock mode (step S43 / YES), the main processing unit 101 does not give any instruction to the screen display processing unit 104 and does not notify the user 300 that there is a received mail (step). S44).

  When the lock state is the normal mode or the mail transmission / reception partial permissible lock mode (step S43 / NO), the main processing unit 101 notifies the user 300 that the mail has been received through the screen display processing unit 104 and receives it. Whether or not to display a mail list screen is selected and displayed (step S45).

  Then, the user 300 designates and inputs whether or not to display the received mail list screen through the key operation input processing unit 103. The key operation input processing unit 103 accepts the input list screen display permission designation and transmits it to the main processing unit 101 (step S46).

  Next, the main processing unit 101 makes a determination with reference to the list screen display availability designation transmitted from the key operation processing unit 103 (step S47).

  When it is specified not to display the list screen display availability (step S47 / NO), the screen display processing unit 104 displays on the screen that the received unread mail exists to the user 300 (step S48).

  When it is specified to display the list screen display availability (step S47 / YES), the determination is made with reference to the lock state recorded in the control data recording unit 106 (step S49).

  When the lock state is the mail transmission / reception partial permissible lock mode (step S49 / NO), the main processing unit 101 notifies the user 300 that the received mail list cannot be referred to via the screen display processing unit 104 (“received mail”). "List not available") is displayed on the screen and notified (step S50). When the lock state is the lock mode, the presence of the received mail is not displayed on the screen (step S44). Therefore, the determination of the lock state when it is specified to display the list screen display permission / rejection is the mail transmission / reception partial allowable lock It is determined whether the mode is the normal mode.

  If the lock state is the normal mode, the main processing unit 101 refers to the received mail recording unit 107 to obtain a list of received mails (step S51), and sets the source mail address of each received mail as a key. Then, the name corresponding to the corresponding mail address is searched from the telephone directory data recording unit 105 (step S52). Then, the main processing unit 101 determines a name search result (step S53).

  If the name can be acquired (step S53 / YES), it is determined that the name is displayed as the received mail list (step S54). If the name cannot be acquired (step S53 / NO), the received mail list is displayed. It is determined that the sender mail address is displayed (step S55).

  Subsequently, the main processing unit 101 displays the received mail list on the screen of the user 300 through the screen display processing unit 104 (step S56), and the user 300 receives it through the key operation input processing unit 103 and the screen display processing unit 104. A received mail is selected from the mail list, and the text of the received mail is displayed (step S57).

  According to this embodiment, according to the lock state set based on the user's intention, it is possible to control services that can be provided at a stepwise level with respect to mail transmission / reception. For example, if the lock state is set to the normal mode, the mail transmission / reception function of the mobile phone can be used as usual. If the lock state is set to the mail transmission / reception partial allowance lock mode, mail can be sent without referring to the phone book data, and mail reception can be performed without resetting the lock state to the normal mode. It is possible to recognize what happened. If the lock state is set to the lock mode, it is possible to suppress all mail transmission and reception services. The reason is to maintain the lock state in stages and change the services that can be provided for mail transmission / reception at each stage.
