The mail address comparison unit 15 compares the e-mail address included in the address book information with the transmission source address of the received mail stored in the common reception folder 14. When the e-mail address included in the address book information matches the sender e-mail address of the received mail, the e-mail address comparing unit 15 displays the entry of the e-mail address in the common reception folder operation table 17 as “display / reply”. Update to “Yes” (details will be described later). The buffered address book information is deleted from the buffer, for example, when it is determined that the communication connection with the smartphone 2 has been disconnected, or when a predetermined time has elapsed.

  The common reception folder operation unit 12 operates the received mail stored in the common reception folder 14 according to the common reception folder operation table 17. For example, the common reception folder operation unit 12 extracts from the common reception folder 14 an e-mail whose transmission address is the e-mail address whose entry in the common reception folder operation table 17 is “displayable / replyable”. The common reception folder operation unit 12 instructs the display unit 104 to output a list of extracted electronic mail information as a response to the received mail list display instruction. Upon receiving this instruction, the display unit 104 outputs a list of e-mail information extracted by the e-mail address comparison unit 15 as a response to the received mail list display instruction. In the received mail list display, the received mail information is sorted according to a predetermined standard. The predetermined standard is, for example, a reception time, a sender mail address, or the like.

  In addition, the common reception folder operation unit 12 updates the common reception folder operation table 17 when, for example, a predetermined cycle or a predetermined event occurs. The predetermined event is, for example, storing a new received mail in the common receiving folder 14, deleting a received mail from the common receiving folder 14, disconnecting communication with the smartphone 2, or the like.

  The common reception folder 14 is generated in the storage area of the RAM 102b of the mobile tablet terminal 1, for example. In the common reception folder 14, information on received mail received by the mail receiving unit 13 is stored. The received mail information includes, for example, the text of the received mail, the transmission source mail address, the destination mail address, the reception time, the transmission time, and the like.

  FIG. 4 is a diagram illustrating an example of the common reception folder operation table 17. The common reception folder operation table 17 stores the transmission source mail address of the received mail stored in the common reception folder 14 and whether or not a predetermined operation can be performed on the transmission source mail address.

  The common reception folder 14 stores received mails of a plurality of users who use the mobile tablet terminal 1. Therefore, the source address of the received mail in the common reception folder may include an e-mail address that is not related to the user who is currently operating the mobile tablet terminal 1. In the first embodiment, an e-mail address not related to a user who is currently operating the mobile tablet terminal 1 is an e-mail address that is not included in the address book stored in the smartphone 2 possessed by the user. That is. Therefore, in 1st Embodiment, transmission of the email to the email address which is not contained in the address book stored in the smart phone 2 which the user who is operating the portable tablet terminal 1 possesses is not permitted.

  For this reason, in the first embodiment, the initial value of the entry operation item in the common reception folder operation table 17 is, for example, “hidden, reply not possible”, and the operation on the mail address of the entry is not permitted. . If the e-mail address included in the address book information of the smartphone 2 matches the source e-mail address of the received e-mail, the e-mail address comparing unit 15 operates the entry in the common reception folder operation table 17 for the e-mail address. The item is updated to “Display, reply possible”. The common reception folder operation unit 12 displays the received mail of the transmission source mail address in which the operation item of the entry of the common reception folder operation table 17 is “display, reply”. Therefore, the received mail whose mail address not included in the address book information of the smartphone 2 is the sender mail address is filtered and not displayed on the received mail list display screen.

For example, in the example shown in FIG. 4, the operation item is “hidden, reply impossible” for both address A and address B entered in the sender mail address of the common reception folder operation table 17. This indicates that received mails from address A and address B are not displayed in the received mail list display, and that e-mails destined for address A and address B cannot be transmitted.

  The mail address entered in the common reception folder operation table 17 is managed by the common reception folder operation unit 12 so as to be the same as the transmission source addresses of a plurality of received mails stored in the common reception folder 14, for example. For example, when a received mail having a new sender mail address is stored in the common receiving folder operation table 17, an entry of the new sender mail address is added to the common receiving folder operation table 17. If there is no received mail whose predetermined mail address is included in the common reception folder 14 as a source mail address due to deletion of the received mail, the entry of the mail address is deleted from the common reception folder operation table 17. Is done.

  FIG. 5 is a functional block diagram of the smartphone 2. The smartphone 2 includes a 3G communication processing unit 21, an infrared communication processing unit 22, an address book management unit 23, and an IC card communication processing unit 24 as functional blocks. The 3G communication processing unit 21, the infrared communication processing unit 22, and the IC card communication processing unit 24 perform substantially the same processing as the 3G communication processing unit 11, the infrared communication processing unit 16, and the IC card communication processing unit 121 of the mobile tablet terminal 1. Therefore, explanation is omitted.

  The address book management unit 23 manages the address book information 23a. The address book information 23a is stored, for example, in the RAM 102b of the storage unit 102 of the smartphone. In the address book information 23a, for example, associations such as e-mail addresses, telephone numbers, and names are stored. For example, when a request for the address book information 23 a is received from the mobile tablet terminal 1, the address book management unit 23 reads the address book information 23 a and transmits it to the mobile tablet terminal 1 through the IC card communication processing unit 24 and the infrared communication processing unit 22. To do. Note that an e-mail address included in the address book information 23a may be transmitted, or all information included in the address book information 23a may be transmitted.
