Is a dark lamp, and when the dark key 10 is pressed, the dark lamp 11 blinks and the printing becomes a dark mode. As described above, each key has a one-to-one correspondence with the operation.

(Problems to be Solved by the Invention) However, in the above case, an operation key must be added to add a new function. Therefore, the size of the operating portion becomes large and the cost increases. Also, if you add a key every time you add a function, the number of keys will increase,
Operability is reduced.

SUMMARY OF THE INVENTION It is an object of the present invention to eliminate the above-mentioned drawbacks of increasing the number of keys, increasing the size of the operating portion and increasing the cost, and providing a method for solving these drawbacks.

(Means for Solving Problems) According to the present invention, in a key operation method in an electronic blackboard device in which a control section instructs an operation operation based on an operation key when the operation key is pressed, a plurality of operation keys are provided in a matrix. Different operation from the operation unit and a key input detection unit that encodes an operation signal generated by pressing a predetermined combination of different operation keys or an operation signal generated by a combination of pressing a predetermined operation key multiple times A key press combination storage unit that stores a table in which codes and operation contents are associated with each other based on combinations of key combination presses and operation key presses multiple times, and output contents of the key input detection unit and key press combination storage unit table And the operation contents based on the combination of operation key presses and the combination of multiple presses are output to the control unit. A time print mode in which the time is printed on the paper based on the combination of different operation keys, a clock setting mode in which the date is displayed, and an alarm timer mode informing when the preset time is reached. And a function of setting a local test mode in which individual devices can be separated and tested based on a combination of pressing the operation keys multiple times.

(Operation) An operation signal generated by pressing a combination of predetermined different operation keys or a combination of pressing a plurality of predetermined operation keys is coded by the key input detection unit,
The key input determination unit compares the output of the key input detection unit with the table of the key press combination storage unit, selects the operation content based on the combination of operation key presses and the combination of multiple presses, and outputs it to the control unit for control. This section sets the time print mode that prints the time on paper based on the combination of different operation keys, the clock setting mode that displays the date, and the alarm timer mode that notifies you when the preset time is reached. Set a local test mode that can test individual local modes based on a combination of multiple presses of. In this way, preset functions can be given and desired functions can be expanded.

Therefore, the above problems can be eliminated and the object can be achieved.

(Embodiment) FIG. 1 is a diagram showing an example of a combination of operation keys according to the present invention.
In the figure, (1), (2), and (3) show examples of combinations of predetermined different operation keys pressed, and (4) shows examples of combinations of predetermined operation keys pressed multiple times. .

The example (1) in FIG. 1 shows a case where the time print mode is set.

The screen stop key is a key for stopping the movement of the white sheet, and in this case, it is defined as a basic key for pressing a combination of different operation keys as an additional function. That is, the return key is simultaneously pressed while pressing the screen stop key. Then, in this case, the time printing mode of the additional function can be set in the electronic blackboard device.

In the example of (2), the clock setting mode is set by pressing the screen stop key and the clear key at the same time. Further, in the example of (3), the alarm timer setting mode is set by simultaneously pressing the screen stop key and the dark key.

Next, a combination of pressing operation keys multiple times will be described. This is shown as an example in (4) of FIG. 1. In this case, immediately after the power is turned on, the clear key is pressed three times, and then the screen stop key is pressed three times. By pressing the above two keys a plurality of times, the electronic blackboard device transits to the local test mode. Next, although not shown in the figure, individual local modes can be executed by pressing the enter key and pressing the send key. Various local tests are possible and can be increased by changing the value of the register.

2 to 4 show an example of the processing flow according to the present invention.

FIG. 2 shows an outline of a main routine in control. After the power is turned on, the idle routine is looped through the initial set routine. When the key is pressed in this state, the processing jumps to the key processing subroutine shown in FIG. In FIG. 3, if the screen stop key is input,
If the branch is made, the white sheet is stopped if the white sheet is being moved, and if not, nothing is done and the key processing subroutine is exited. Key input is (screen stop + return)
When the key is pressed, the time print mode flag is set and the process returns. When the (screen stop + clear) key is pressed, the time setting process is performed and then the process returns. When the (screen stop + dark) key is pressed, the alarm timer setting process is performed and then the process returns.

Next, when the clear key is pressed three times and the screen stop key is pressed three times, the local test process shown in FIG. In this way, it is possible to define a new function by pressing a combination of predetermined different operation keys or a combination of pressing a plurality of predetermined operation keys.

FIG. 5 is a functional block diagram showing a configuration example for realizing the present invention.

Data control is performed according to the control flow described above. As an example, the operation unit 11 has a display unit 11-a and a key matrix 11-b in the arrangement configuration shown in FIG. When a key is pressed from the key matrix 11-b (assuming a combination of a screen stop key and a clear key is pressed), the operation signal is coded by the key input detection unit 12 and sent to the key input determination unit 13. The key input determination unit 13 compares the output of the key input detection unit 12 with the code data of the key storage combination storage unit 14 for determination. As a result, when the input operation key is found to be a combination of (screen stop key and clear key), it is determined to be the clock setting mode. Based on this determination result, the control unit 15 starts the operation of the clock setting mode. That is, the control unit 15 instructs the display control unit 17 to perform the predetermined display, and the display control unit 17 displays the display instructed on the display unit 11-a, for example, the year, in this case, "86". Number of printed sheets display area 1
Go to step 5 (see Fig. 6) and prompt the operator for the next operation. If the display is correct, the operator operates the feed key 13 (see FIG. 6), and if there is an error in the display, correct data is sent to the key matrix 11-b with the 10-position number key 6 and the 1-position number key 7 (see Input (see Figure 6). The input data at this time is coded by the key input detection unit 12, passed through the key input determination unit 13, sent to the control unit 15, the data is set in the clock unit 18 and displayed on the display unit 11-a. . Thereafter, necessary data such as month, day, hour and minute are displayed in order, and the same operation is repeated until the setting is completed.

Similarly, when the combination of (screen stop key + return key) is pressed down and the print instruction is issued, the control unit 15 sends the font data for time printing to the print control unit 18, and the printer 19 prints it on the paper. Print the time.

In the above description, when it is not necessary to print the time on paper and the time print mode is to be reset, the initial state can be returned by pressing the combination of (screen stop key + return key) again, for example. . This can be similarly performed when resetting the other modes.

As other mode settings, the alarm timer setting by pressing the key (screen stop key + dark key) from the key matrix 1-b and the local test mode setting by pressing the key (clear key 3 times → screen stop key 3 times) are also the above. Similarly, it can be performed by the functions of the key input determination unit, the control unit, and the like.

The above-mentioned setting of the alarm timer is used when the time of the discussion is limited according to the agenda in order to facilitate the proceedings of the agenda. For example, it is set whether the alarm buzzer sounds when a preset time has elapsed. In the example of FIG. 6, it is possible to display (set) in two digits,
In this case, the alarm buzzer can be set to sound after a maximum of 99 minutes.

As described in detail above, different operation key combinations can be assigned to optional functions that are relatively less used by the user, and combinations of operation key presses can be complicated, so that a service engineer for maintenance can use them. It is conceivable to assign them to etc.

(Effects of the Invention) As described in detail above, according to the present invention, even with a small number of keys, a predetermined combination of different operation keys is pressed,
Alternatively, if a predetermined combination of operation keys is pressed a plurality of times, the function can be expanded, and the purpose of use can be selected according to the operability.

In other words, the number of keys is not increased in order to increase the functions, but can be performed by a combination of key operations, so that there is an advantage that it can be put to practical use without increasing the cost. Also, the function selection by pressing a combination of different predetermined operation keys or a combination of pressing a predetermined operation key multiple times is added by software, and it is easy to change the function without changing the printed wiring board. There is an effect that can be.
