FIG. 1 is a flow diagram for explaining the operation of an embodiment of the present invention. Next, the operation of one embodiment of the present invention will be described in detail with reference to FIGS. 1 to 6.

First, the captain center transmits, for example, image data representing the major classification screen 21 to the terminal device 21.

When the captain ADP9 receives the image data transmitted from the captain center via the modem/NCLj13, it processes the data and provides it to the CPLJ8. The CPU 8 stores the image data in a video RAM included in the RAM 11, and displays the image data stored in the video RAM on the display 2 as a screen 21.

In step 81 (abbreviated as Sl in the figure), if there is a key power, the CPU 8 first reads out an image identification code from the video RAM storing the display image in step S2, and based on the read image identification code, Checks input to see if key input is valid.

For example, display! When something other than the product screen is displayed on I2, the order key 54 is invalid, and when the order processing screen is displayed, the backward key 56 is invalid. In step $3, the CPU 8 checks whether or not the stop/end key 55 has been pressed, and if it determines that the stop/end key 55 has been pressed, it ends the operation, but if not, it proceeds to step S4. move on. In step S4, the CPU 8 determines whether the numeric key 51 has been pressed.

Here, when the user looks at the screen displayed on the display 2 and selects and inputs the number corresponding to the product group he/she wants to see, the CP
U8 gives the input data to captain ADP9,
At step 813, Captain ADP 94
8 modem/NCU 13 to the captain center, and the process returns to step S1 again.

Here, if the user presses the wrong number key 51, the user presses the clear key 53. CPU8 performs step S5
When it is determined that the Klinaki-53 has been pressed,
A code indicating what should be corrected is transmitted to the captain center, and the process returns to step S1.

To select a screen, the user presses the number keys 51 and then the # key 52.

Here, since what is displayed on the display 2 is a product screen, the process proceeds from step S8 to step 315 through steps 82 to S8, and in step S15, the captain sends a code indicating that the selected screen should be sent. Send to center. Based on the transmitted data, the captain center extracts image data to be transmitted to the terminal bag f11 from the data file and transmits it to the terminal bag w1.

In step 816, when the CPU 8 of the terminal device 1 receives the image data transmitted from the captain center,
The data is stored in the video RAM and displayed on the display 2 in the same manner as described above. Subsequently, in step 817, the CPU 8 reads an image identification code that specifies the displayed image from the video RAM, and returns to step S1 again.

When the user wishes to re-view the screen that was viewed immediately before, the user presses the backward key 56. When the backward key 56 is pressed, the process advances from step S7 to step 315, and a code indicating that the captain center is requested to transmit the immediately previous screen is transmitted.

When the user operates the numeric keys 51 and # key 52 in response to the image displayed on Display-2, the CPU 8 repeats steps 81 to S8 and 815 to 817 described above.

When the image showing the product desired by the user is displayed on the display 2, the user presses the order key 54. Accordingly, C
PLJ8 advances from step S6 to step S14, and R
The storage area 110 of the AM 11 is searched and the product code is read out based on the read image identification code.

Subsequently, in step 815, the CPU 8 transmits the read product code to the captain center.

The sweet potato center sends a confirmation screen 25 shown in FIG. 6 to the terminal device 1 in order to request the user to confirm the order. Similarly to the above, when the CPU 8 receives the image data transmitted from the captain center in step 816, it displays the confirmation screen 25 on the display 2, reads the image identification data in step 317, and stores it in the RAM 11. .

The user follows the instructions displayed on the confirmation screen 25 and confirms NO.
If it is K, then input r88#J, for example, and input r99#J manually, for example, to correct it. C.P.
If U8 determines that r99#J has been keyed,
The process proceeds from step S9 to step 815, and a code indicating that the order should be corrected is sent to the captain center. However, if CPLI8 determines that r88 #J has been keyed, in step 310, confirmation 0 is sent. Send a code to the captain center indicating that
Subsequently, in step S11, the total purchase amount by the user is calculated, and in step 812, a slip is printed by the printer 6, and the operation C is ended.

In the above embodiment, the image data including the image identification code is stored on the video RAM, but the image data including the image identification code is stored in the video RAM.
providing another storage means for storing the II identification code;
Image identification code and video RA stored in the storage means
The image data stored in M may correspond to each other.

Effects of the Invention As described above, according to the present invention, when an image displayed on the display means is designated by the designation means, the image identification data for identifying the image stored in the image data storage means is changed to the identification data. Since the generating means generates the data and the reading means reads the processing code corresponding to the image identification data from the table, the terminal device side can perform processing in response to the displayed image, and the terminal device side can perform the processing code corresponding to the image identification data. This has the advantage that it is possible to create application programs that respond to images.
