When a signal is input from the keyboard 7,
A character is displayed on the display element 9 and a character segment 11
A long sentence can be displayed by controlling the microcomputer so that the character displayed in the box moves.

FIG. 5 illustrates the relationship between an input signal from the keyboard 7 and the display element 9 based on a flowchart of a program of the microcomputer 8.

The normal program is executed in step S2 of the flowchart.
-Circulating any of the steps of S20. The S1 step is performed only once because the initial state is set. In step S2, the presence or absence of a key input on the keyboard 7 is determined.

When, for example, a key operation for selecting a cooking menu is performed on the keyboard 7, the information is input into the microcomputer 8, and it is determined in step S2 that there is a key input. It reaches S3 step. In this step, an operation state for displaying the cooking menu is set, and the program proceeds to step S4. If it is determined in step S2 that there is no key input, step S3 is skipped and the process proceeds to step S4, so that the operation state is not changed. In step S4, the display content is determined according to the operation state. Thereafter, the process proceeds to step S5, where it is determined whether the display is the moving display or the still display.
Thereafter, a process of moving and displaying characters one by one for each TM1 is performed. If it is determined in step S5 that the display is the still display, the process proceeds to step S15, and thereafter, the process of displaying the still display between TM2 is performed.

In step S6, it is determined whether or not TM1 is counting time.
M1 is counted down, and in step S8, TM
It is determined whether or not 1 has elapsed 200 msec. If not, the process proceeds to step S14 to output a display to the display element. If it has elapsed, the character string is moved by one character in step S9, and the process proceeds to step S10. If the TM1 is not being counted in step S6, the processing in steps S7 to S9 is skipped, and the process proceeds to step S10. In step S10, one character to be displayed is read, and in step S11, it is determined whether the read character is a character indicating the end of display. If not, one character is set in the display buffer in step S12. Then, in step S13, 200 msec is set in TM1. Further, S1
The display is output in four steps, and the process returns to step S2. S
If it is determined in step 11 that the character is a display end character, S20
The process proceeds to the step, the display buffer is cleared, and the process returns to the step S2.

In step S15, it is determined whether or not TM2 is being counted. If so, the countdown of TM2 is performed in step S16, and in step S17,
If it is determined that one second has elapsed in TM2, the flow shifts to step S20 to clear the display buffer in the same manner as described above.
Return to step. If one second has not elapsed in TM2 in step S17, the process proceeds to step S14, where a display is output, and the process returns to step S2. Further, if TM2 is not counting in step S15, the process proceeds to step S18 to read the character string, and in step S19, sets the character string in the display buffer, and proceeds to step S14.
The display is output and the process returns to step S2.

FIG. 6 shows the display state of the display element 9 when the vegetable key 21 of the (AUTO) automatic cooking key 15 is operated. The character segment 11 turns on / off the 14 character elements 12. The character is expressed by doing. When the vegetable key provided in the AUTO selection key is operated, (VEGETABLE--P
(RESS START) is displayed by moving the display character.

FIG. 7 shows a display state of the display element 9 when the RICE key 22 of the (AUTO) automatic cooking key 15 is operated. When the RICE key 22 is operated, (RICE- −ADD WATER −
-PRESS START--) is displayed, and when the start key 18 is pressed, the high-frequency heating apparatus starts heating, and after a certain time has passed, the display element 9 displays (ADD RICE-
−PRESS START−−) is displayed.

By moving the characters on the display as described above, it is possible to display a long sentence necessary for the high-frequency heating device, which was not possible conventionally, and it is possible to provide more information to the display element. It has also become possible to provide information on cooking that could only be obtained.

FIG. 8 is a block diagram showing a display control unit of the high-frequency heating device of the present invention. As shown in FIG. 8, the control unit 23 includes a microcomputer 25 for performing control for displaying characters (or symbols) on the display element 24,
An operation panel 26 is provided in the microcomputer 25.
Key operation discriminating means 28 for discriminating which key is pressed when a key 27 is pressed;
Operation state setting means 29 for setting and storing the operation state of
A display content determining means 30 for determining the content to be displayed according to a key operation; a character string table 31 for continuously storing character strings to be displayed; and a plurality of timers 32 and 33 for measuring whether or not a predetermined time has elapsed. , A display buffer 34 for temporarily storing information to be output to the display element 24, and a character control unit 35 for outputting character information to the display buffer 34. The display buffer 34 is provided with a number of memories 36 to 41 corresponding to the number of display digits (the number of characters) of the display element 24. When character information is input to the memory 36, the content is converted into a signal for directly driving a display element by passing through a decoder 42 and displayed on the display element 24.

In the present invention, the display on the display element is configured to move from one end to the other end. In order to realize this, in the embodiment of the present invention, the display buffer 3 for six characters is used.
By rewriting the contents of Nos. 6 to 41 at regular intervals, the display appears to move. This will be described with reference to the flowchart shown in FIG.

When the display is moved, the following steps are performed from the step shown in S6 of FIG. First S6
One timer 32 for measuring whether or not a certain time has passed when passing through is activated. If the fixed time has not elapsed, the process proceeds to S7 and the timer is counted down. S
In step 8, it is determined whether a predetermined time (200 milliseconds) has elapsed. If the time has elapsed, the character string in the display buffer 34 is moved in step S9. Specifically, when moving the character to the left, the contents of the memories 36 to 41 in the display buffer 34 in FIG. To 3
Move the contents of 7 to 38 and the contents of 36 to 37, respectively.
Further, the process proceeds to S10 of FIG.

The one-character reading in S10 is an operation in which the character control unit 35 in FIG. As shown in FIG. 10, the character strings in the character string table 31 are divided by adding a symbol ＠ between the character strings 43 and 44 as an end symbol 45 indicating the end of one character string. The symbol indicating the end of the character string may be other than the symbol shown in the embodiment. By attaching a symbol indicating the end of a character string in this manner, character strings having different numbers of characters can be successively stored in the character string table, so that the memory can be used efficiently. Also, the character string can be easily changed or added.

Proceeding to S11 in FIG. 5, it is determined whether or not the character read in S10 is the symbol ＠ indicating the end of the character string. If it is a symbol, the flow advances to S20 to delete all the contents of the display buffer 34. If the character is not the @ symbol in S11, the process proceeds to S12, and the character is displayed in the display buffer 34.
Is written to the memory 36 in the inside. Then, the process proceeds to S13, where the timer 32 is set for a predetermined time (200 milliseconds), and then the process proceeds to the next step. In S14, the contents of the display buffer 34 shown in FIG. Through these series of steps, the display content moves on the display element from one end to the other end.

FIG. 11 shows operation instruction information for notifying the user of the next operation and the operating state of the apparatus by combining the stationary information providing display and the moving information providing display using the display element shown in FIG. The displayed status display information is divided and displayed. After the output (POWER) key is operated, the set output level (HIGH) is set.
Status display information is statically displayed, and the next operation instruction (--SET

It is determined whether the time set to 2 has elapsed or not, and if not, the process proceeds to step S14 to output a display to the display element. If it has elapsed, the character string is moved by one character in step S9, and the process proceeds to step S10. If the timer 32 is not counting in step S6, the processing in steps S7 to S9 is skipped, and the process proceeds to step S10. In step S10, one character to be displayed is read. In step S11, it is determined whether the read character is a character indicating the end of display.
In step S12, one character is set in the display buffer.
Then, the moving speed of the display is determined in S12.1. This determination is made depending on the value (state) of the operation state flag 46 in FIG. For example, in the case of FIG. 17, if the operation state flag 46 is 100 (line a in FIG. 17), it is determined that the moving speed of one character is set to 400 ms, and if it is 010 (line b in FIG. 17). For example, the setting is made in 200 milliseconds.

When it is determined that the time is 400 milliseconds in S12.1,
Proceed to S12.2. In S12.2, the timer 32 is set to 40.
Set in 0 milliseconds. Next, the display is output in step S14, and the process returns to step S2.

When it is determined in S12.1 that the time is 200 milliseconds,
Proceed to S13. In step S13, 20 is set in the timer 32.
0 msec is set, and the routine proceeds to step S14.

If it is determined in step S11 that the character has been displayed, the process proceeds to step S20, where the display buffer is cleared, and the process returns to step S2.

By pressing the key 77, the "1 MIN" key 78, and the "10 MIN" key 79 in order, a special display mode called a sales promotion demonstration mode can be set and solved.
That is, the functions mounted on the high-frequency heating apparatus, that is, the cooking menu are sequentially moved and displayed using the display element, and the operation procedures of those functions are also moved and displayed using the display element. More specifically, in the popcorn function explanation display, "POPORN" is first displayed, and then "3.5 OZ" → "PRESS START" →
The display appears in the order of "3MIN00SEC" and the time counts down. After the countdown is completed, the function of the automatic decompression will be described. First, "AUTO DEFROST"
Is displayed and "SETWEIGHT" → "1.0 LBS"
→ “2.0 LBS” → “3.0 LBS” → “PRESS S”
“TART” is displayed, and finally “5MIN40SEC” is displayed and the time is counted down. That is, POPC
We are trying to buy a product equipped with this high frequency heating device by moving and displaying menu names such as ORN and AUTO DEFROST automatically and continuously using a display element without first pressing a key. In addition to appealing to customers, it also moves and displays the operation method, so it can give the customer the image that it is a very warm and friendly product, which is an advantage for dealers selling this high frequency heating device Is big.

FIG. 43 shows an example of an operation panel of the high-frequency heating device. For example, a "VEGETABLE" key 80 is
Press the key twice to use "FROZ" as shown in Fig.3.
"VEGETABLE" is displayed, and when the "VEGETABLE" key 80 is pressed again, "FRESH" is displayed.
VEGE TABLE "is displayed. When these menu keys are pressed, such as the" VEGETABLE "menu key 80, it is necessary to confirm the display of the menu name. Therefore, a six-digit display tube as shown in FIG. 3 is used. In the case, immediately after pressing the first key, "FROZEN" is displayed leftward and displayed after a while, "VEGETABLE"
It is easier to understand by moving and displaying (easy to check),
Next, when the key is pressed, "FRESH" is displayed leftward, and after a while, "VEGETABLE" is moved and displayed. These displays will be described with reference to FIG. When the "VEGETABLE" key is pressed in the clock display state (Stage 1), "FROZEN" is displayed leftward, and the time is one second (Stage 2). If the key is not pressed, it is every 0.5 seconds The characters are sequentially moved and displayed digit by digit (stages 2 to 14), and then "VEGETABLE" is again displayed.
When the "E" key is pressed, "FRESH" is displayed leftward, and the time is one second (stage 15). If the key is not pressed, characters are displayed one digit at a time every 0.5 seconds. (Stage 16-17), "VEGE again
Pressing the “TABLE” key displays “FROZEN” from left to right, and the time is 1 second (Stage 1
8) The same operation is performed after the stage 19. When this menu display is completed, the next operation instruction information is displayed, which is shown in FIG. 45 by “SET WEIGHT”, “PR
"ESS START" is displayed, and moving display is output sequentially from one end of the display element and at regular intervals (stages 1 to 38).

When the menu display is completed, the next operation instruction information is displayed. This is indicated by “SET WEI” shown in FIG.
"GHT" and "PRESS START" are displayed, but are moved and output sequentially from one end of the display element and at regular intervals. However, the last letter "T" of the display "SET WEIGHT" is 6 digits. After the display element has disappeared from the display element, that is, after the display element has become all blank, the next display "PRESS START" is moved and displayed.
FIG. 45 The stage 19 and the stage 38 are all blank.

Note that the number of character segments is 5 or more and 10
Less than one month is practical. This is because most menu names can be displayed if the number of character segments is 5 or more. If the number of character segments exceeds 10, the display section becomes too large, and it is necessary to reduce the size of the characters or the operation panel. Is gone.
