However, in the above conventional example, the sensitivity of the touch panel switch is high,
In addition, since each key has the same sensitivity, there is a disadvantage that important information is deleted when a key such as "delete" is accidentally pressed by a careless operation of the user.

Therefore, in order to solve this inconvenience,
When a key such as "Delete" is pressed, the display screen is displayed so that the contents of the deletion are reconfirmed on the display, and the key arrangement is devised to prevent accidental pressing. However, there is a problem that the operability is deteriorated and the screen configuration is complicated.

[0008]

SUMMARY OF THE INVENTION An object of the present invention is to remedy the disadvantages of the prior art, especially when the user presses a key.
It is an object of the present invention to provide a touch panel input device capable of immediately and accurately determining whether the operation is a normal operation or an erroneous operation.

[0009]

Therefore, according to the present invention, there is provided a touch panel switch for receiving a pressing operation, a key input confirming unit for outputting information on the pressed position and the pressed time of the pressed operation, and a key input confirming unit. Based on the input key information from the switch confirmation unit, a switch confirmation unit that determines the input key based on the pressed position information and outputs the input key information, a timer table that stores the effective depression time set for each function of the input key, and A timer selection unit that reads effective press time information corresponding to the input key from the timer table, and externally inputs data by a press operation based on the press time information from the key input confirmation unit and the effective press time information from the timer selection unit. And a key input determining unit for determining whether output is possible. This aims to achieve the above-mentioned object.

[0010]

During operation of the touch panel input device, the touch panel switch receives a pressing operation for data input. The key input confirmation unit outputs the pressed position information and the pressed time information of the pressed operation to the switch confirmation unit and the key input determination unit. The switch checking unit determines the input key based on the pressed position information from the key input checking unit and outputs the input key information. That is, based on the coordinates given to each key, which key is input at the pressed position is output as input key information. Further, the timer selecting unit reads out the valid press time information of the input key from the timer table based on the input key information. The key input determination unit determines whether input data can be externally output by the pressing operation based on the pressing time information from the key input checking unit and the valid pressing time information from the timer selecting unit.

Since the effective press time set for each input key is stored in the timer table, the effective press time is set according to the importance of each input key. Only when there is a certain input, data input by the key is accepted.
In this way, erroneous operations such as accidentally depressing an important key are avoided.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS.

The embodiment shown in FIG. 1 includes a touch panel switch 6 mounted on an LCD display unit for receiving a pressing operation, a key input confirming unit 4 for outputting information on the pressing position and pressing time of the pressing operation, A switch confirmation unit for judging an input key based on the depression position information from the confirmation unit and outputting the input key information; a timer table storing effective depression times set for each input key; Timer table 3 based on input key information
A timer selection unit 2 for reading the effective press time information of the input key from the key input confirmation unit 4 and an external output of input data by a press operation based on the press time information from the key input confirmation unit 4 and the effective press time information from the timer selection unit 2. A key input determining unit 1 for determining whether the key input is permitted or not. The overall operation timing is controlled by a control unit (not shown).

Here, the timer value stored in the timer table 3 can be freely set and changed.

Next, the operation of this embodiment will be described with reference to the flowchart of FIG.

Here, an example in which the present invention is applied to a facsimile apparatus as shown in FIG. 3 will be described. In addition, the timer table 3 includes, for example, “numeric keypad 8”.
It is assumed that a timer value of “15 ms” is set in advance for “b”, and a timer value of “100 ms” is set in advance for “delete key 8a”.

(1). In order for the user to input the facsimile number of the transmission destination, an input waiting state (step S in FIG. 2)
Numeric keypad 8b displayed on LCD display section in 1)
Is pressed (step S2 in FIG. 2).

(2). The key input confirming unit 4 performs the LC input based on the signal (press information) from the touch panel switch 6
It analyzes which part of the D display unit was pressed and notifies the switch confirmation unit 5 (step S3 in FIG. 2).

(3). The switch confirmation unit 5 confirms the screen displayed on the LCD display unit (Step S in FIG. 2).
Confirm the switch arrangement as shown in FIG. 3 together with 4) (step S5 in FIG. 2).

Then, input data is obtained from the pressed position information from the key input confirmation unit 4 and the switch arrangement information, and is notified to the timer selection unit 2 (step S6 in FIG. 2).

(4). The timer selection unit 2 searches the timer table 3 based on the input data from the switch confirmation unit 5 (Step S7 in FIG. 2), and extracts a timer value (Step S8 in FIG. 2).

For example, if "3" is pressed on the LCD display unit, the timer value of "15 msec" is notified to the key input determination unit 1.

When the "delete key 8a" on the LCD display is pressed, a timer value of "100 ms" is notified to the key input determination unit 1.

(5). The key input determination unit 1 determines whether input data is valid or invalid based on the timer value from the timer selection unit 2 and the pressing information from the key input confirmation unit 4.

That is, when the key input determination unit 1 receives the press information from the key input confirmation unit 4 (step S in FIG. 2).
9) Start measuring the pressing time (step S1 in FIG. 2)
0). Then, when the pressing time reaches the timer value from the timer selecting unit 2, it is checked again whether or not the touch panel switch 6 is pressed according to the pressing information from the key input confirming unit 4 (step S11 in FIG. 2).

If the touch panel switch 6 is pressed, it is determined that the pressing is a normal operation (step S12 in FIG. 2).

On the other hand, if the touch panel switch 6 is not depressed, it is determined that the depression is due to an erroneous operation (step S13 in FIG. 2).

That is, in this embodiment, the "numeric keypad 8b"
Is "15 msec" or more, and "Delete key 8a" is "100 m
If it is not pressed for more than "seconds", it is not determined that the pressing is a normal operation.

That is, for a key which is continuously pressed a plurality of times, such as the numeric keypad 8b, the timer value is set to a small value so that the key can be input by light pressing, thereby enabling high-speed key input with high sensitivity. .

Conversely, for a key such as the "delete key 8a" for which a simple input is not desired, the timer value is set to a large value so as to be effective only when the user consciously presses it, and the sensitivity is low. Key input.

Normally, when inputting numeric keys, the key input operation is performed quickly, and there is a high probability that another key is erroneously pressed at this time. In the present invention, since the sensitivity is changed in accordance with the importance of the key, the "delete key 8
Even if "a" is pressed, it is ignored and the ten key input can be continued as it is.

As described above, according to the present embodiment, the key input sensitivity can be set according to the function, so that it is immediately determined whether the key input is due to a normal operation or an erroneous operation. In addition, the determination can be made with high accuracy, and even if an important key is pressed by an erroneous operation, the key is ignored and normal key input can be continued.

[0033]

According to the present invention, the switch confirmation unit determines the input key based on the pressed position information from the key input confirmation unit and outputs the input key information. Since the timer selecting unit reads the effective press time information corresponding to the input key from the timer table based on the input key information, the effective press time information set for each input key can be acquired at high speed. Further, the key input determining unit determines whether the input data can be externally output by the pressing operation based on the pressing time information from the key input confirming unit and the valid pressing time information from the timer selecting unit. If the input is less than the valid pressing time, the input can be treated as invalid. In this way, by setting the effective pressing time according to the importance of each input key, data input by the key can be accepted only when there is a reliable input with a long pressing time for an important key, It is possible to avoid erroneous operations such as accidentally depressing an important key. For example, continuous like a numeric keypad
For keys pressed multiple times, key press
Set the timer value as small as possible to
While enabling quick key input, it is
The user is conscious of keys that do not require easy input.
Set the timer value large so that it is valid only when pressed
Key input with low sensitivity.
At the time of key input, the key input operation is performed quickly.
There is a high probability that another key is pressed by mistake
Changes the sensitivity according to the importance of the key,
If you accidentally press the "Delete key" during
Thus, the ten key input can be continued as it is.
