Then, the above numerical data is written to the address of the image storage unit 25 corresponding to the quantity display unit 76 of the corresponding product name key 73 on the product list screen of FIG.

In step s53, it is determined whether or not a new numerical value is input, and if the numerical value is input, the above operation is repeated to update and input the input buffer in the working area 40. If it is possible to input a numerical value, it is determined that the quantity input is completed in step s54, the data in the input buffer is transferred to the corresponding quantity part 58 in the product code table area 39, and the processed flag F is set to "0" in step s55. Set, and in step s56, the first operation shown in Fig. 14 (1)
The reverse display of the display mode is canceled and only the serial number portion 75 of the product name key 73 is reverse displayed. The state is shown in Fig. 14 (2).
The details are shown in FIG. 13 and will be described later.

By repeating such processing, a desired product name and its quantity can be sequentially specified on the product list screen shown in FIG. On the other hand, if the determination in step s42 is affirmative, that is, if the order completion key 82 is operated on the product list screen, the process proceeds to step s5.
Move to 7, product code table area 39 shown in screen number B1
The inversion bit in the attribute of the processing code of the displayed character is reset, and the processing proceeds to FIG.

(E) Input Confirmation Process FIG. 12 is a flowchart showing the input confirmation process on the order confirmation list screen shown in FIG. In step s60, the screen count value PCNT and the item number counter D
CNT and CNT are reset to "0" respectively. Step s61
Then, based on the screen number B1 and the screen count value PCNT,
The corresponding unit area 52 of the commodity code table area 39 shown in FIG. 7 is selected. In step s62, the selected unit area 5
2, based on the item number count value DCNT, an area relating to one product name, that is, an information item area 91 shown in FIG.
Read out.

In step s63, it is determined whether or not the flag portion 59 of the read information item area 91 is "1". If this judgment is affirmative, it means that the information has already been input, and therefore, in step s64, the product code, product name and quantity data are stored in the communication buffer formed in the working area 40, and step s65. Move to. If the determination in step s63 is negative, it means that no information input operation has been performed on the information item area 91, and step s64
Move to step s65 without going through.

In step s65, the item number count value DCNT is incremented by 1, and the process proceeds to step s66. In step s66, it is determined whether or not the item number count value DCNT exceeds the maximum value n. If the determination result is negative, it means that all the product names in the same unit area 52 are not scanned in the product code table 39 shown in FIG.
Returning to s62, the above-described processing is repeated.

If the determination in step s66 is affirmative, it is determined in step s67 whether the screen number count value PCNT matches the parameter SPCNT. If they do not match, it means that the scanning regarding the screen number is in the middle in the product code table area 39 shown in FIG. 7, and in step s68, the screen number count value PSNT is incremented by +1 and the process returns to step s61. Repeat the process.

If they match in the judgment at step s67, it means that the scanning has proceeded to the part corresponding to the final screen of the product code table area 39, and at step s69 the screen number corresponding to the order confirmation list screen shown in FIG. C1 is generated and stored in the working area 40. In step s70, one unit area 47 in the image file area 37 shown in FIG. 6 is selected based on this screen number C1. In step s71, the fixed image data in the selected unit area 47 is stored in the image storage unit 25.
Transferred to This fixed image data is composed of data other than the product name column 71 on the product list screen shown in FIG.
It is combined with the communication buffer data that stores the information list.

In step s72, the keyboard number B2 in the selected unit area 47 is read in the image file area 37 and stored in the working area 40. In step s73, the data in the communication buffer area formed in the working area 40 is expanded and stored in the image storage unit 25 as a bit image. As a result, the generation confirmation list screen shown in FIG. 19 is displayed on the liquid crystal display device 24, and a key format based on the keyboard number C2 is set on the key matrix panel 28.

(F) Product Name List Display Processing FIG. 13 is a flowchart showing the processing steps of product name display. The reverse display of the display screen described with reference to FIG. 8 is performed according to the flowchart of FIG. When moving from the menu screen shown in FIG. 17 to the product list screen shown in FIG. 18, the product code table shown in FIG.
The selected product name data is sequentially displayed by the screen number of 39, and the product name is displayed over a plurality of screens by screen switching (previous page or next page) operation.

On the other hand, the operator touches the product name key 73 in FIG. 19 to input the product name for ordering, and the item column, that is, the product name key 73 as a whole is highlighted to make a selection. The name of the product is notified. By further operating the numeric keys, the quantity is entered and displayed on the quantity display section 76. When this entry is completed, the highlighted product name key 73 is canceled and only the serial number section 75 is highlighted. It In addition, this reverse display, even if the screen is switched by operating the previous page key 85 or the next page key 86, etc., and the screen returns to the original screen again, the serial number section 75 of the above input product is displayed in reverse and has been input. You can check the products. That is, a display effective for displaying a large number of data with a small screen size can be obtained.

In displaying the product list screen shown in FIG. 19, first, in the image file region 37 shown in FIG. 6, the display attribute data is read from the display attribute region 50 for each unit region 47, and the display start position of each product name, that is, the image. The start address DA of the storage unit 25 and the size data indicating the display range are output. The start address DA is added to the start address DA by multiplying the soft code value read from the product code table 39 for each information item area 91 by a predetermined coefficient, and then adding the start address DA.
Start address DA is formed in working area 40 at
It is held in a register. This is because the soft code has a correlation with the key-formatted partitioned display mode. Screen count value PCN in step s81
The T + soft code value is calculated, this is generated as serial number data, and a code indicating the numerical character for displaying the numerical value is output.

In step s81, it is determined whether or not the flag portion 59 of each information item area 91 is "1". If the determination is affirmative, it means that the product name has already been input with information. In step s83, the serial number code The inversion flag included in the attribute data is set, and the process proceeds to step s85. If the judgment in step s82 is negative, step s
At 84, the inversion bit included in the numeric code of the attribute data is reset, and the process proceeds to step s85.

In step s85, the numerical code of the serial number data is written in the display start address DA of the image storage unit 25. At this time, if the inversion bit of the numeric code attribute data is set, the serial number dot data is inverted and stored in the image storage unit 25, and consequently displayed as an inversion pattern. This inverting circuit is shown in FIG.

The inverting circuit 92 of FIG. 15 includes an address counter 93, a character code register 94, and an attribute data register 95. The outputs of the address counter 93 and the character code register 94 are output as the address data of the character generator 23. . The inverted bit data is output from the attribute data register 95.

The output of the character generator 23 is input to the bit conversion unit 96. The bit conversion unit 96 includes, for example, a plurality of exclusive OR circuits 97. That is, if the inversion bit is "1", the bit data output from the character generator 23 is inverted and output. If the inversion bit is "0", the bit data output from the character generator 23 is output as it is. The output of the bit conversion unit 96 is written in the image storage unit 25.

In step s86, the address is added to the start address DA by the number of characters of the serial number data and held as the start address DA.

Subsequently, in step s87, a character code string of "quantity:" is generated, and in step s88, it is determined whether or not the reversal flag RE is "1". If affirmative, the inversion bit in the character code attribute data is set in step s89. If the determination in step s88 is negative, the process proceeds to step s90 without passing through step s89. Step s90
Then, the character data “quantity:” is expanded from the start address DA of the image storage unit 25.

Next, at step s91, data α2 for the number of characters of the character code string is added to the start address DA and stored as the start address. Then, in step s92, the quantity data is read from the quantity area 58 of the information item area 91 indicated by the item number count value DCNT and the soft code, and is stored in the image storage unit 25 based on the start address DA as in the above processing. .

Further, in step s93, the calculation is performed by adding the data α3 corresponding to the number of characters of the quantity data to the start address DA, the result is stored as the start address DA, and in step s94, the product name of the information item area 91 set in the same manner as in step s92. The product name data is read from the unit 57 and loaded from the start address DA into the image storage unit 25. Further, in step s95, calculation is performed to add the data for the maximum number of characters of the product name to the start address DA, and the result is held as the start address DA.

Such an operation is executed for each of the processing of expanding the various display data in the processing described in FIGS. 10 to 12 into the image storage unit 25, the processing of inverting the display, and the processing of canceling the inversion. Become.

In the case of an instruction to perform reverse display, the process proceeds to step s96, the reverse flag RF is set to "1", and the product name data, the character code string of the quantity data and the reverse bit in the attribute data are set. . After this, the process proceeds to step s80.

On the other hand, when the instruction to cancel the reverse display is issued,
The process proceeds to step s98, and the inversion flag RF is set to "0".
Set to. Next, in step s99, product name data,
The character code string of the quantity data and the inversion bit in the attribute data are reset, and the process proceeds to step s80.

(G) Interrupt processing FIG. 16 is a flowchart showing the above-mentioned interrupt processing. When the handset 34 is picked up by the terminal device 1 at the time of display other than the telephone screen shown in FIG. 16 such as during the product order input work described with reference to FIG. 18, the hook switch 35 detects this and goes into the off-hook state. 16 The display is switched to the telephone screen shown in the figure and telephone calls can be made. On the other hand, when the handset 34 is attached, the processing screen immediately before picking up the handset 34 is restored, and the processing can be continued.

When the interrupt signal is supplied from the communication device 32, the input controller 29, etc., the main body controller 17 shifts the processing to the flowchart shown in FIG. 16 in order to execute data processing in response to the interrupt request. That is, when the interrupt signal is supplied, the subsequent interrupt processing is invalidated in step m1, and the device which has generated the interrupt request corresponding to the content of the interrupt request sends it to the bus line 19 or the input control unit 29. Fetch data from the associated bus line. At step m3, it is determined whether or not the hook switch 35 is on. If this determination is negative, then in steps m4 and m5 it is determined whether or not the hook switch 35 is off and whether or not the input control unit 29 is an interrupt.

If the determination in step m3 is affirmative, the process proceeds to step m6, and it is determined whether or not the screen number B1 of the screen currently displayed is the number corresponding to the telephone screen. If this judgment is negative, the telephone flag TF is set to "1" in step m7. In step m8, the various registers and count data in the working area 40 and the image data in the image storage unit 25 are all transferred to the save area, for example, the bank switching area 42. After this, the process proceeds to step n3 in FIG. 8 and the subsequent interrupt process is validated in step m9. If the determination in step m6 is affirmative, the process immediately moves to step m9.

If the hook switch 35 is off, step m4
If it is detected by, the process moves to step m9
Judge whether TF is "1". If this determination is affirmative, the telephone flag TF is reset to "0" at step m10, and at step m11 the above various data is transferred from the save area such as the bank switching area 42 to the working area 40 and the image storage unit 25. Transfer, and the process returns to step m9. If the determination in step m9 is negative, the process immediately returns to step m9.

If the determination at step m5 is affirmative, at step m12, the hard code corresponding to the touch-operated key is fetched from the input control unit 29, and the input processing shown in FIG. 11 is performed at step m13. This post-processing returns to step m9.

In this way, in this embodiment, the terminal device 1 and the central processing unit 14 or the relay device 13 are connected online so that the order processing can be performed. As a result, the ordering work can be performed at any time, and the ordering work can be performed quickly.

In this embodiment, when the product name is entered, the product name key
The entire 73 is highlighted so that the product name during the ordering process can be clearly recognized, and errors can be prevented. When the quantity input is completed, only the serial number portion 75 is highlighted on the product name key 73. The reverse display of the serial number section 75 is continuously reversed even when the product order column 71 continues to be ordered or the product name column 71 changes to another page and returns to the original display again. . Therefore, the ordered product name can be recognized immediately and the work efficiency is improved.

Further, in the present embodiment, even if it is necessary to make a telephone call during the ordering work, it is possible to immediately switch to the telephone screen and make a telephone call just by picking up the handset 34. When the handset 34 is placed in the storage recess 6, the hook switch 35 detects the on-hook state, the screen immediately before the work is interrupted is displayed again, and the interrupted work can be continued. This also significantly improves work efficiency.

EFFECTS OF THE INVENTION As described above, according to the present invention, when a call is to be made with a handset, the image data and the input data being displayed are stored in the storage output based on the off-hook detection output by the hook switch detection means, and the call is stored. The call operation can be performed by switching to the image used for the operation. When the handset call ends and an on-hook detection output is obtained, the stored image data and input data are displayed again on the display input means, and the operation is continued. As a result, convenience is significantly improved and work efficiency is further improved.
