This document detection signal is input to the CPUI. The modem unit 8 is composed of G3, G2, Gl, and FM modems and a clock generation circuit connected to these modems, and modulates the transmission data stored in the RAM 3 under the control of the CPU, It is output to the telephone line 10 via the NCU 9. Furthermore, the modem section 8 introduces the analog signal of the telephone line 10 via the NCU 9, modulates it to 8t, and stores the binarized data in the RAM 3.

The NCU 9 switches and connects the telephone line to either the modem section 8 or the telephone set 11 under the control of the CPUI. Telephone l1 is integrated with a facsimile device,
The dial operation part is integrated with the operation section 12.
Specifically, the telephone 11 includes a handset, a speech network, a dialer, a numeric keypad, a one-touch key, and the like. The operation unit 12 includes a key for starting transmission, reception, etc.
It consists of a mode selection key that specifies the operating mode such as fine, standard, and automatic reception during transmission and reception, and a numeric keypad. Note that the CPU detects the pressed state of these keys and controls each of the above-mentioned parts according to the pressed state. The display unit 13 is, for example, a liquid crystal display that displays 16 digits, and displays predetermined characters, etc. under the control of the CPUI, and is normally arranged on the operation unit 12. FIG. 2 is a plan view showing a specific configuration of the operating section l2. This operation section l2 includes a numeric keypad and an on-hook button l7.
Also provided is a card placement section 14 into which a card 15 storing a telephone number is inserted. The card l5 used in this embodiment includes a liquid crystal display section 15a that displays the other party and his/her telephone number, and a liquid crystal display section 15a that displays the other party and his/her telephone number.
Various touch keys are provided for switching the display and inputting data. Among these, the transfer button 16 is for instructing to transfer the telephone number displayed on the display section 15a to the operation section 12 side. FIG. 3 is a schematic diagram illustrating the principle of signal transfer between the card 5 and the operating unit 2. The card 15 of this embodiment is an optical type that transfers signals without contact, and has 10 light emitting elements 18 corresponding to the numbers O to 9.
have. By blinking these light emitting elements 18 at a predetermined timing, telephone number information and check code (TNCC) are transferred to the operation unit 12 side. The check code is a 4-digit number obtained by performing a certain calculation on the above phone number. Note that this code is automatically added when a phone number is registered on the card 15. On the other hand, the card arrangement section 14 is provided with ten light receiving elements l9 corresponding to each light emitting element l8 of the card l5. Further, this card placement portion l4 is provided with a microswitch 20 that detects that the card 15 has been inserted, and when this microswitch 20 is pressed down due to the attachment of the card l5, each of the light receiving elements 19 is activated. This is a standby state. In the above structure, when making a call using the card 15, the display section 15a is displayed while the card 15 is attached to the card placement section 14 or before the card 15 is attached to the card placement section 14. , search for the person you want to call and its telephone number, and place the call on the display section 15a. Then, when the transfer button 16 is pressed with the card 15 attached to the card placement section 14, the telephone number displayed on the display section 15a is sequentially transferred to the operation section 15 by the light emitted from the light emitting element 18. transferred to the side, then
The check codes listed in E are transferred to the operation unit 12 in order. These transfer information will be sent from the operation unit 12 to cptyi. FIG. 4 is a flowchart showing the operation of the facsimile machine in this case. When the facsimile machine is in the slow-down state, the CPUI periodically refers to the state of the card placement section 14, and when the microswitch 20 is pressed, the card 15 is
Detects the attachment of the . Further, when the handset of the telephone 11 is raised or the on-footer button 17 is pressed, the NCU 9 is controlled to be connected to the line. Then, when the transfer button 16 of the card 15 is pressed and the telephone number information is input from the card 15 (S 1),
The CPUI analyzes the numbers that are input in sequence,
This number is sequentially stored in RAM3 <(S2). Next, the CPU performs the same calculation as that performed on the car 115 side for the input phone number information (S3), and compares this with the check code that is input manually following the phone number information (S3). ). Then, if the two numbers match, it is determined that it is a valid telephone number, and the telephone number stored in RAM 3 is called up and sent to the telephone line 10 (SS
). Further, if the calculated value in S3 and the check code do not match, it is determined that the telephone number is invalid, no call is made, the telephone number in RAMa is deleted, and the system returns to standby. In this way, calls can only be made when the correct phone number is transferred. In particular, in the configuration of this embodiment, since each light receiving element 19 in the card placement portion l4 enters a standby state when the card 15 is installed, malfunctions caused by external light can be prevented. Note that the present invention is not limited to the above embodiments. For example, it goes without saying that the present invention can be applied to communication devices other than facsimile devices.

Furthermore, storage media are not limited to optical ones that transfer data without contact. Furthermore, it is not limited to so-called cards, but can be widely applied as long as it has a phone number storage function and is portable. [Effects of the Invention] According to the present invention, it is possible to check whether telephone number information is appropriate based on a check code input from a storage medium, and it is possible to always make an appropriate call.
