The card storage section provided on the lower surface of the switch panel 6 has the structure shown in FIG. That is, it has a guide plate 12 on the bottom surface extending in the insertion direction from the card insertion slot 7, and a connector 13 is provided at the end of this guide plate 12. A contact portion that fits into the connector 13 is provided at the tip of the card indicated by 30 . The card 30 has a built-in memory such as a ROM storing a program for creating graphs or a RAM for storing created data together with a battery.
A switch pattern corresponding to the contents of this memory is printed on the surface.

Card installation is not limited to the sliding type.
It may be done by an opening/closing method.

FIG. 4 shows a circuit configuration of an embodiment of the present invention, and in FIG. 4, 14 indicates a microprocessor.

In relation to the microprocessor 14, ROM1
5, a RAM 16 and a keyboard 17 are provided to constitute a microcomputer device. The keyboard 17 includes the keyboard 2 and numeric keypad 4 shown in FIG. Microprocessor 1
A display drive circuit 18 is arranged between the display unit 3 and the display unit 3 . Furthermore, the microprocessor 14
Printer (not shown) via I/O port 19
It is also possible to connect to a telephone line via an interface 24.

A microprocessor 14 writes digital data to or reads digital data from the card 30 via the connector 13 and the I/O port 20. A scanning circuit 21 and a reading circuit 22 are provided for the switch panel 6, and an interface 23 is arranged between these circuits and the microprocessor 14.

A predetermined DC voltage is applied to all of the conductive patterns L1 to L5 of the switch panel 6 shown in the figure, and a scanning pulse at a ground level is sequentially supplied from the scanning circuit 21 to the conductive patterns P1 to P6. When any of the touch switches on the switch panel 6 is turned on, the output signal of a predetermined conductive pattern corresponding to the position of the touch switch becomes the ground level at a predetermined timing. By supplying this output signal to the reading circuit 22, the key code corresponding to the touch switch turned on is supplied to the microprocessor 14.

FIG. 5 shows a state in which a card storing an automatic dialing program is inserted into the card storage section in this embodiment. Necessary switch patterns corresponding to the positions of the 30 touch switches on the switch panel 6 are printed on the surface of this card.

is a sorting pattern that arranges registered telephone numbers in alphabetical order by category. 34 is a pattern used at the time of calling. 35 is a redial pattern used when the other party is busy. 36 and 37 are
This is a pattern for displaying call time and call charges.

When a card with the above pattern printed on it is inserted, the automatic dialing program stored on the card is loaded. Then, the initial screen is displayed on the display unit 3. This initial screen displays, for example, a menu for registering and sending a telephone number.

For example, the menu for registering a telephone number is executed as follows. First, by operating the touch switch corresponding to the pattern 31, a category such as relatives, friends, etc. is specified. Items that have already been registered in this designated category are displayed on the display section 3. Names and the like are entered by key operations on the keyboard 2, and telephone numbers are entered using the numeric keypad 4. After confirming the input displayed on the display unit 3, press the touch switch corresponding to the pattern 32 to complete the registration of the telephone number.

When the touch switch of the sort pattern 33 is pressed, the telephone numbers registered in each category are rearranged in alphabetical order.

Further, when a category is specified as the transmission mode, a list of already registered telephone numbers in that category is displayed on the display section 3. In this list, as shown in FIG. 5, the desired telephone number is designated by moving the cursor, and the touch switch corresponding to pattern 34 is pressed. When the user presses the execution key on the keyboard 2, a dial signal for the specified telephone number is sent to the telephone line. At this time, if the call is busy, redial pattern 3
By pressing the touch switch 5, the same telephone number can be sent again.

The registered phone number is stored in the memory of the card. Therefore, even if the card is removed from the main body, if the card is then inserted into the main body, automatic dialing can be performed by the same operation as described above. In addition, multiple people can use one main unit in common by having their own cards.
