Abstract

PURPOSE:To make a facsimile equipment low-priced and to reduce the space of a control panel by using one part of an LCD for showing the resolution of the facsimile. CONSTITUTION:After turning a power source ON, an input/output port 11 is initialized by a CPU 4. Afterwards, a picture character showing 'normal resolution' is displayed at the left edge of an LCD 1 and an initial picture is displayed in the other area through the input/output port 11 and an LCD controller 12. When pushing down a resolution switch 8, the picture character at the left edge of the LCD 1 is switched to a character showing 'fine resolution'. When pushing down the resolution switch 8 again, the character is switched for showing 'resolution half tone'. Further, when pushing down the resolution switch 8 again, the character is switched for showing the 'normal resolution'.

An input/output port 12 is connected to the input/output boat 11 and is connected to the input/output port 11 to drive the LCD 1, and is connected to the input/output port 11 via a data bus, and transmits the state of input signals to the CPU 4 and outputs signals according to the instructions of the CPU 4. This is an LCD controller that controls the

Next, the operation will be explained.

After the power is turned on, the output port 9 and the input/output boat 11 are initialized by the CPU 4, the LED 2a lights up, and the initial screen is displayed on the LCD 1 via the input/output boat 11 and the LCD controller 12. resolution switch 8
When is pressed, the CPU 4 monitors it through the input port door, turns off the LED 2a through the output port 9, and
Turn on LED2b. In other words, the resolution switches from normal mode to fine resolution mode. resolution switch 8
When is pressed again, CPU4 goes to LE via the same route as above.
Turn off D2b and turn on LED2c. In other words, the resolution switches from fine resolution mode to halftone mode. When the resolution switch 8 is pressed again, the CPU 4 turns off the LED 2c and turns on the LED 2a using the same route as above. In other words, the resolution switches from halftone to normal mode. The above control program is stored in the ROM5.

[Problem to be solved by the invention]

Since the conventional facsimile machine is constructed as described above, it requires an LED to display the resolution, which has the problem of making the control panel smaller (and increasing cost).

The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a facsimile device that can display resolution without using an LED for resolution display.

[Means to solve the problem]

The facsimile apparatus according to the present invention is such that the LCD, which conventionally displays facsimile operating procedures, etc., also has a resolution display that displays pictograms indicating the resolution.

[Effect]

In addition to adding a resolution display to the LCD that displays operating procedures, etc., the facsimile machine according to the present invention can reduce the space of the control panel a little.
Moreover, it can be made inexpensive.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a part of a control panel of a facsimile machine according to an embodiment of the present invention. This is an LCD with a dot matrix structure.

FIG. 2 shows the configuration of a control system of a control panel of a facsimile machine according to an embodiment of the present invention. In Figure 2, 14.5, 6.7.8, 1
1.12 is the same as that in FIG.

Next, the operation will be explained.

After the power is turned on, the input/output board 11 is initialized by the CPU 4, and then a pictogram indicating "normal resolution" as shown in FIG. The initial screen is displayed in the area. When the resolution switch 8 is pressed, the CP
U4 monitors it via the input port door, and switches the pictogram at the left end of the LCDI to the one indicating "fine resolution" in FIG. 5(b) via the input/output port 11 and LCD controller 12. When the resolution switch 8 is pressed again, the CPU 4 switches the pictograph at the left end of the LCDI to one indicating "resolution halftone" in FIG. 5(C), using the same route as above. When the resolution switch 8 is pressed again, the CPU 4
The pictogram at the left end of the LCD 1 is switched to the pictogram on the left end of the LCD 1 shown in FIG.

In the above-mentioned embodiment, the dot matrix and the square have 7 dots in the vertical direction and 5 dots in the horizontal direction in FIG. 5, but the same effect can be obtained even if the number of vertical and horizontal dots is not the above.

Further, in the above embodiment, a pictogram indicating the resolution is placed at the left end of the LCD, but it may be displayed anywhere, such as at the right end.

Further, in the above embodiment, the LCD controller 12 is connected via the human output boat 11, but the LCD controller 12 may be configured to directly interface with the CPU 4.

FIG. 6 shows the configuration of the second embodiment of the present invention, and its operation will be explained. After titON, LC
The D controller 12 is initialized by CPtJ4,
At the left end of the LCDI, a pictogram indicating "normal resolution" as shown in FIG. 5(a) is displayed, and the first w1 screen is displayed in other areas. When the resolution switch 8 is pressed, the CPU 4 monitors it via the manual port door, and changes the pictograph at the left end of the LCD 1 to the one indicating "fine resolution" in FIG. 5(b) via the LCD controller 12. Switch. resolution switch 8
When is pressed again, CPU 4 uses the same route as above to connect to LC.
The leftmost pictogram of DI is shown in Figure 5 (“Resolution Halftone” of C1).
Switch to the one that shows. When the resolution switch 8 is pressed again, the CPU 4 uses the same route as above to switch the pictogram at the left end of the LCD to the one that indicates "normal resolution" as shown in FIG. 5(a).The above control program is stored in the ROM 5. There is.

〔Effect of the invention〕

As described above, according to the present invention, since a part of the LCD is used to indicate the resolution of the facsimile, the apparatus can be made inexpensive and the space required for the control panel can be reduced.
