[0009]

A portable telephone according to the present invention comprises:
It is characterized in that a telephone call is made by connecting an external memory storing data of telephone information, and searching and displaying necessary data from the external memory.

[0010] A memory card storing data of telephone information and a telephone body having a display section and a key operation section are provided, and the memory card is easily mounted on the telephone body.

Further, the memory card is a read-only memory.

[0012]

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of a mobile phone according to the present invention.

The present embodiment shown in FIG.
And a ROM card 2 plugged into this mobile phone
And a display 3 attached to the mobile phone 1 for displaying data, a button switch 4 for making a simple call, and a key panel 5 for performing key operations.

FIG. 2 is a diagram for explaining the display on the display of FIG.

Next, the operation of this embodiment will be described in more detail with reference to FIGS.

A mobile phone user connects the ROM card 2 to the mobile phone 1. This connection is performed by a slot-in system in which the ROM card 2 is directly inserted into the mobile phone body. The ROM card 2 has a read-only memory (R) in which telephone numbers, addresses, detailed information, and the like are stored for each item.

The search name is displayed on the display 3, the search is executed by pressing a key on the key panel 5, and the search result is displayed on the display 3.

As shown in the display image of FIG.
On the page, search name, telephone number (TEL), address (AD)
S) is displayed, and a map and detailed information (opening time, closing time, etc.) are displayed as attached information on the next page. The display screen of each page is switched by a key operation of the key panel 5.

That is, in addition to the memory originally built in the mobile phone 1, phone numbers, addresses, maps, detailed information, etc. for each genre (restaurants, entertainment facilities, hotels, etc.) prepared in advance by the manufacturer as an extended memory. RO that stores the data of
By connecting M to the mobile phone 1 as the ROM card 2, necessary information can be quickly searched. Based on this search result, a call can be made with one touch by pressing the button switch 4 as necessary.

As described above, an unknown telephone number is quickly searched for when a mobile phone is used, the search result is displayed on the display 3, and a call is made by pressing the button switch 4. It is desirable that the ROM card 2 to be connected has a size and a shape such that a plurality of types can always be carried. For example, the size and weight of a cash card are ideal.

FIG. 3 is a flowchart for explaining the operation of the embodiment of FIG.

Referring to FIGS. 3 and 1, a ROM card 2 as an external memory is connected to the mobile phone 1 (step 0: S0). Next, the name of a public facility to be searched is entered by pressing a key on the key panel 5 of the mobile phone 1 (step 1: S1). A determination is made in step 2 (S2) as to whether or not the searched facility name has been searched. If not, the operation ends (step 3: S3). If the search is successful, the data is displayed on the display 3 (Step 4: S
4). Here, the necessity of transmission is determined in step 5 (S5). If the transmission is unnecessary, the operation proceeds to step 6 (S6) to end the operation. If a call is required, the button switch 4 is pressed to make a call connection (step 7: S7), and the operation after the connection is terminated.
