Display control means for reading and displaying the operation display element of the corresponding element number.

In the operation / display device of this electronic device, when one of the contents to be displayed on the dot graphic display, for example, one of a menu, an input mode, an output mode, and an output phase is selected,
The image numbers are sequentially read from the image arrangement table memory corresponding to the element numbers in accordance with the display contents, the image data corresponding to the image numbers are read from the image data memory, and the image is displayed in the operation display unit in operation element units. To be displayed on the dot graphic display. In this operation / display device, when it is desired to partially change the image arrangement for the same display content, for example, for a menu screen, this can be realized by changing and storing the image number corresponding to the element number in the image arrangement table memory. In addition, when it is desired to display a part of an image peculiar to the display content, this can be realized by storing the image data peculiar to the image data memory.

(E) Examples Hereinafter, the present invention will be described in more detail with reference to examples.

FIG. 2 is a block diagram showing an electronic circuit configuration of a control device in which the present invention is implemented. The control device includes an operation display unit 3 including a dot graphic display 1 and a transparent touch panel 2 disposed on the upper surface of the dot graphic display 1, an input circuit 4 for receiving an operation input signal from the transparent touch panel 2, ROM 5 for storing image data to be processed and image arrangement data, CPU 6 for executing operation processing, display processing and control processing, RAM 7 for storing display data and calculation data, and driving the dot graphic display 1 And an input / output circuit 9 for inputting / outputting a control signal.

The operation display unit 3 has the same size as shown in FIG.
It is composed of 16 operation display elements D having the same shape and four other fixed display sections D ₁ , D ₂ , D ₃ , D ₄ . Each operation display element D can be selectively operated, and
Element numbers of 00, 01,..., 0F are given for each position. The fixed display elements D ₁ , D ₂ , D ₃ , and D ₄ are composed of SEALER TEMP, SEALING TIME, and CONTENTS as shown in FIG.
And the display of TOTAL and the current value and target value are displayed, and these are not planned to change the pattern (the numerical value may change). SEALER TEMP, SEALING TIM above
The display of the selected one of E, CONTENTS and TOTAL flashes and lights.

However, the feature of this embodiment is that 16 operation display elements D
In the part. One of the images shown in FIG. 4 is displayed on these operation display elements D. Which image is displayed is stored in advance corresponding to the operation display number for each display content, and is determined by the stored content. For each display content, for each operation display element, what image is displayed, that is, the image layout is changed by changing the storage,
Can be changed freely.

FIG. 5 shows an image data table allocated and stored in the ROM 5. In this table, the image numbers and the image data of the prepared image numbers shown in FIG. 4 are stored in pairs. Each image data is a set of dot (“1”, “0”) data of a matrix corresponding to one operation display element, although the contents are different.

FIG. 6 shows an image arrangement data table allocated and stored in the ROM 5. Here, the horizontal axis represents element number 00,
.., 0F, the display contents are arranged on the vertical axis, and as the data contents, what image is displayed in the operation display element of each element number for each display content is stored by the image number. . This table is an example in the case where CONTENTS is selected, and the display contents include a count time, an input correction, an input mode, an output mode, an output phase, and the like in addition to the menu screen. Although not shown, SEALER TEMP, SE
ALING TIME and TOTAL also have similar image arrangement data tables.

The image and image data tables shown in FIGS. 4 and 5 and the image arrangement data table shown in FIG. 6 are prepared in advance by the manufacturer. The user changes the image arrangement,
Alternatively, when a new image is to be added, it is possible to easily respond to this user request by storing the arrangement in the ROM at the time of production.

Next, the operation display operation of the control device of the embodiment will be described.

When the power is turned on, the operation display unit 3 displays an image such as “control”, “select”, and “reset”. Here, the operator
Assume that you want to check the output phase of CONTENTS among the functions of SEALER TEMP, SELECTING TIME, CONTENTS, and TOTAL. When the operator operates the selection of the operation display unit 3 to select CONTENTS, the screen of the operation display unit 3 changes next,
SEALER TEMP blinks and lights, and images of reset, selection, setting, etc. are displayed during control. Here, if the determination is operated, the setting of SEALER TEMP can be modified. However, since the assumption is related to CONTENTS, the operator further operates the selection. In response, the screen of the operation display section 3 changes again, and SEALING TIME blinks and lights. If you operate the selection again, the screen changes again, and this time CONTENTS blinks and lights. Here, when the operator operates the determination, the operation display unit 3 displays FIG.
A menu screen is displayed as shown in FIG. The same processing operation is performed for each display until the menu screen is displayed. Here, the display operation when the menu screen is selected as the display content will be described with reference to a flowchart shown in FIG.

As described above, when the determination is operated by blinking CONTENTS, the menu screen is selected as the screen Ci to be displayed (step ST1). Next, the variable I is set to 1 in order to designate 00 among the operation display elements 00,.
ST2). Here, I = 1 indicates element number 00, and I = 16
Indicates element number 0F. Next, the image number (01 in FIG. 6) of the element number 00 of I = 1 on the menu screen is read out with reference to the image arrangement data table of the ROM 5 (step S1).
ST3). Subsequently, the image data “under control” is read from the image data table of the ROM 5 by the read image number 01, and this image data is read as the element number I of the display memory of the RAM 7,
That is, transfer to the area corresponding to 00 (step ST
Four). Then, the variable I is incremented by one, and I = 2
(Step ST5), then it is determined whether or not I> D (= 16) (step ST6). If I = 2, this determination is NO, so the process returns to step ST3, and this time returns to I = 2 on the menu screen. The image number 00 of the corresponding element number 01 is read from the image arrangement data table (step ST3), and the read image number 00 is read.
Reads a blank from the image data table (step ST4). This image data is stored in element number 1 of the display memory.
That is, transfer to the area corresponding to 01 (step ST
Five). Then, similarly to the previous time, the variable I is incremented by 1 to make I = 3 (step ST5), and it is determined whether I> D (step ST6). If I = 3, the determination is NO, so the process returns to step ST3. Return and step S until I> 16
Repeat the processing of T3 to ST6, sequentially read the image numbers stored in the element numbers 00, ..., 0F of the menu screen column of the image arrangement data table, read the image data from the image data table by these image numbers, Transfer to display memory. When the transfer is completed, the image data in the display memory is displayed on the operation display unit 3. FIG. 1 (A) shows an example of the display.
Is shown in When the variable I exceeds 16, the determination in step ST6 becomes YES, the normal control processing is executed, and the control processing is continued until any key, that is, the operation display element is operated next (step ST7, step ST7). ST8). Next, when any operation display element is operated, the determination in step ST8 is YES.
Then, the process returns to step ST1 to shift the operation of displaying the operated display content.

Now, in the menu screen of FIG.
When D, that is, the output phase is selected, an output phase screen is displayed on the operation display unit 3 as shown in FIG. In this output phase screen, the operation display element 00
Is in control, operation display element 01 is set, operation display element 08
To reset, operation display element 09 to cancel, Are displayed respectively, but the operation display elements 02, 03, 04, 0
Blanks are displayed at 5, 0A, 0B, 0C, and 0D, and another display image, “output phase, タ イ ム time-up L → H, time-up H → L” is superimposed and displayed.

FIGS. 1 (A) and 1 (B) are display examples of a menu screen and an output phase screen to the last, and the user can, for example, specify the positions of the “controlling” and “reset” images on the menu screen. If you want to replace, at the time of production, display contents of image arrangement data table of ROM5, element number of menu screen
This can be realized by storing the image number 00 in 00 and the image number 01 in the element number 01. Of course, by storing image data other than the image shown in FIG. 4 in the image data table, it is also possible to freely arrange and display images unique to the user.

In the above embodiment, the number of operation display elements of the operation display unit 3 is 16, which is a part of the whole. However, the entire display unit may be used as the operation display element.

Further, in the above-described embodiment, the control device has been described as an example. However, the present invention is not limited to this, and can be widely applied to an operation / display device of a power device such as a television and a video device.

(F) Effects of the Invention According to the present invention, a plurality of image data are stored in the image data memory, and the image data is stored in the image arrangement table memory for each element number in accordance with the content to be displayed according to the operation state. The image number of the combination selected from the above is stored and displayed on the operation display unit in accordance with the contents of the image arrangement table memory. Therefore, it is necessary to supply an image according to a user's request at the time of production. Can be. Further, even when a user requests an image that is not stored in the image data memory, such as a unique mark or symbol, the creator only needs to create the image data and store it in the image data memory. Therefore, in contrast to the conventional operation / display device in which display figures and characters are formed by printing using an original plate or molding using a mold, an image is formed only by changing data in a memory as in the present invention. Since the contents can be changed, the operation display section of the device can be changed according to the user's request with little time and cost,
