[0002]

2. Description of the Related Art Display / operation panels using an analog touch panel are used not only in copying machines and facsimiles but also in various devices. Among them, the analog touch panel method that calculates the coordinates of the pressed position on the resistive film by applying a DC voltage across the resistive film of the touch panel and detecting the potential at the pressed position on the resistive film is a digital touch panel method. Compared with the advantage that the resolution of the pressed position coordinates can be increased, it is also used in the AD series basic machine operation panel and the like.

Further, Japanese Patent Application Laid-Open No. 5-19940 discloses that
A tablet that outputs the X and Y coordinate position as an analog signal of current change by pressing an arbitrary point on the conductive film, and the analog signal from this tablet is converted into a set of digital values in the X and Y directions. And a correction device for outputting a correct value by correlating the position data including the error output from the detection circuit with the actual position data stored in the conversion table in a one-to-one correspondence. A tablet device is described.

It is controlled by the / P controller 31. The T / P controller 31 detects whether or not the analog touch panel 11 is pressed from the output signal of the detection circuit 32, controls the switches 20 to 23, and supplies the supply signal and the monitoring signal to the terminals 14 to 17 of the analog touch panel 11. The pressed position coordinates of the analog touch panel 11 are calculated from the output signal of the analog / digital converter 30 by switching.

Next, the operation of this embodiment will be described.
For example, a screen as shown in FIG. 2 is displayed on the display panel 18, and the operator presses any key on the screen. The display data displayed by the display panel 18 is stored in the bitmap memory corresponding to the dots of the display panel 18, and this bitmap memory is provided in the LCD controller 19. LCD controller 1

The T / P controller 31 switches 20 and 21 in an initialization data collection routine as shown in FIG.
Is turned on to turn off the switches 22 and 23, the signal from the terminal 14 of the analog touch panel 11 is taken in through the sense amplifier 24, the multiplexer 29, and the analog / digital converter 30, and the signal from the terminal 15 of the analog touch panel 11 is taken in. Are taken in through the sense amplifier 25, the multiplexer 29, and the analog / digital converter 30.

Next, the T / P controller 31 turns off the switches 20 and 21 and turns on the switches 22 and 23, and the signal from the terminal 16 of the analog touch panel 11 is sense amplifier 26, multiplexer 29, and analog / digital conversion. The signal from the terminal 17 of the analog touch panel 11 is taken in via the sense amplifier 27, the multiplexer 29, and the analog / digital converter 30 as well as being taken in via the device 30. The T / P controller 31 stores the signals from the terminals 14 to 17 of the analog touch panel 11 in the memory as initialization data.

Further, the T / P controller 31 is shown in FIG.
Switch 22 in the position data collection routine as shown in
Is turned on to turn off the switches 20, 21 and 23, and a signal input from the terminal 14 of the analog touch panel 11 to the detection circuit 32 via the sense amplifier 24 from the output signal of the detection circuit 32 becomes the comparison level of the detection circuit 32. By detecting whether or not it has reached, it is detected whether or not the analog touch panel 11 has been pressed.

When the analog touch panel 11 is pressed, the T / P controller 31 turns on the switches 20 and 21 and turns off the switches 22 and 23, and outputs the signal from the terminal 17 of the analog touch panel 11 to the sense amplifier 2.

Take in through 0. Next, the T / P controller 31
Turns off the switches 20 and 21 and switches 22 and 2
3 is turned on, and the signal from the terminal 15 of the analog touch panel 11 is taken in through the sense amplifier 25, the multiplexer 29, and the analog / digital converter 30.

Then, the T / P controller 31 calculates the coordinates (input coordinates) of the pressed position of the analog touch panel 11 based on the data thus taken in by the position data collection routine and the initialization data, that is, the resistive film 1
Applied voltage between terminals 14 and 15 of terminals 2 and 13, terminals 16 and 17
The coordinates of the pressed position on the resistance films 12 and 13 are calculated from the voltage applied between the terminals and the signal voltage from the terminals 16 and 15. Therefore, the T / P controller 31 constitutes a coordinate detecting means for detecting the input coordinate.

In the confirmation sequence, the main controller 33 uses the coordinate system corresponding to the dot configuration of the LCD 18 for T /
The input coordinates calculated by the P controller 31 are analyzed to display information on the display panel 18 and the analog touch panel 11
Whether or not there is a key input on the analog touch panel 11 is determined by determining the relationship with the pressed position coordinates (input coordinates) above.

That is, as shown in FIG. 11, the main controller 33 causes the T / P controller 31 to execute the above-mentioned position data collecting routine after waiting for the analog touch panel 11 to be pressed, and input coordinates (analog touch panel) obtained by the position data collecting routine. 11 press position coordinates),
A difference from the center coordinate of the coordinate range of the key input determination corresponding to the dot of the key displayed on the display panel 18 is detected, and it is determined whether or not this difference is within the range (gate range) of the key input determination. By doing so, the analog touch panel 11
The presence or absence of the key input of is judged.

Then, the main controller 33 determines that the position data of the input coordinates is invalid if the difference is not within the key input determination range, and if the difference is within the key input determination range, the key of the analog touch panel 11 is determined. It is determined that there is an input, and the position data of the input coordinates is validated. As described above, the main controller 33 controls the determination means for determining the presence / absence of key input by determining the relationship between the display information on the display panel 18 and the pressed position coordinates on the analog touch panel 11, and a series of execution steps of each unit. And a control means for performing the operation.

In the determination of the presence / absence of the key input, there is an advantage that the display range of each key on the operation display panel and the key input determination range can be managed as the same coordinate area (area data), but the key display is designed. The layout is based on the above point of view. On the other hand, an erroneous input is likely to occur in the input determination of adjacent keys, and a small key may have an uncomfortable feeling due to the influence of parallax or the like.

Therefore, in this embodiment, for example, FIG.
As shown in (b), with respect to the display range of each key on the operation display panel, the range of key input determination is limited to the vicinity of its center and set to an independent area for each key.
It is possible to effectively prevent an erroneous operation of an adjacent key without impairing the operation feeling (there are few people who normally prefer to press the end of the key). Here, conventionally, as shown in FIGS. 3A and 3B, the key display range and the key input determination range (hatched portion) are the same, but in the present embodiment, FIG.
As shown in (b), the range of key input judgment in the shaded area is independent of the display range of the keys.

Further, in the present embodiment, the operation feeling is improved by expanding the range of key input determination within the range where space is allowed even for keys that are displayed in a small size (vertically long) from the viewpoint of design. . Further, the range of key input determination is shifted as a whole against the problem of parallax caused by the angle at which the operation panel is viewed not being perpendicular to the surface of the operation panel, that is, the reference of key input determination is displayed on the display panel 18. A setting function to set independently of information is provided, and this setting function shifts the range of key input determination as a whole to reduce the feeling of strangeness in operation.

As described above, in the first embodiment, one set of terminals 14, 15, 16 and 17 is provided for each of the X electrode 12 and the Y electrode 13 which are superposed, and the terminals 14, 15 of each set are provided. , 16 and 17, a touch panel 11 having a predetermined resistance value, and each terminal 14 to

T / P controller 31 as coordinate detecting means for detecting the pressed position coordinates on the touch panel 11 from the detection signal from
And the display panel 1 provided below the touch panel 11.
8, an LCD controller 19 as a display control means for displaying information necessary for operation, and a main controller 33 as a determination means for determining the relationship between the display information on the display panel 18 and the pressed position coordinates on the touch panel 11.
And an operation panel having a main controller 33 as a control means for controlling a series of execution steps,
Since the display information of the display panel 18 and the reference for determining the relevance of the determination means 33 are independently set, the pressing position determination range is set without being bound by the shape or design on the surface of the operation display panel. As a result, it is possible to realize a feeling of operation according to the intention of the operator.

A concern in the first embodiment is that the deviation of the pressed position and the positional shift due to parallax include variations due to the operator (including the set position and the like). The habit and the parallax of the operator who presses the tip of the triangle displayed on the display panel 18 and the operator who presses the bottom side are slightly different depending on the height and the operation position of the operator.

The second embodiment of the present invention is the embodiment of the present invention as defined in claims 2 to 5, and in the first embodiment, the main controller 33 inputs the difference by key input as shown in FIG. If it is within the range of the determination, the central coordinates of the range of the key input determination are updated by adding the correction as shown in the following formula by a statistical method. New center coordinate = current center coordinate × (n−1) / n + current pressing coordinate × 1 / n Here, n is a constant that can be arbitrarily set by the operator. As a result, the operator-specific information is gradually reflected on the initially set display data to set the range of the key input determination, and the operation feeling can be further improved.

If the current pressed coordinate is significantly deviated from the central coordinate of the current key input determination range (shifted within the key input determination range), the center of the key input determination range is detected. There may be cases where no correction should be applied to the coordinates. In consideration of such a case, a first register for setting a range in which the input coordinate is adopted as the correction data is provided, and the main controller 33 determines whether the input coordinate is within the range set in the first register. Only the above correction is performed. For this reason, it is convenient to prevent chaotic correction.

Further, a second register for setting the value of n in the above equation is provided, and the main controller 33 performs the above correction by n in the second register. For this reason,
The operator can change n in the second register to control the degree of following variations in key input. This is a measure necessary to suppress a sudden change in the feeling of operation and to obtain a required following speed.

Further, since these correction parameters (center coordinates, coordinate correction target range, coordinate correction rate, etc.) are set according to the operator, the main controller 33 determines the initial values of these correction parameters and the current status. The values are individually held by means such as a non-volatile memory, and a procedure is performed such that these parameters are returned to the initial values only by a predetermined procedure (for example, inputting a keyword).

As described above, the second embodiment is an embodiment of the invention described in claim 2, and the X electrodes 12 are overlapped.
And a pair of terminals 14, 15 and 1 for each of the Y electrodes 13.

A D controller 19, a main controller 33 as a determination means for determining the relationship between the display information on the display panel 18 and the pressed position coordinates on the touch panel 11, and a main controller 33 as a control means for controlling a series of execution steps. In the operation panel having the
Since it has a criterion correction function that automatically corrects the criterion for determining the relevance of the above by a statistical method according to the above formula, the error information peculiar to the operator is automatically collected and the relevance determination of the determining means 33 is performed along with it. It is possible to realize a feeling of operation that meets the operator's unique conditions by correcting the reference.

The second embodiment is an embodiment of the invention according to claim 3, wherein in the operation panel according to claim 2, whether or not the statistical data used for the correction is added by the judgment reference correction function. Since it has the first register as the reference value setting means for setting the reference value for determining whether or not, it is possible to put a necessary limitation on the correction and prevent the chaotic correction.

The second embodiment is an embodiment of the invention described in claim 4, wherein in the operation panel according to claim 2, the range of statistical data used for the correction is set by the judgment reference correction function. Since the second register is provided as the statistical data range setting and setting means, an appropriate limit can be given to the automatic correction rate per time, and abrupt fluctuation of the key input determination range can be prevented.

The second embodiment is an embodiment of the invention according to claim 5, wherein in the operation panel according to claim 2, the reference of the relevance judgment corrected by the judgment reference correction function is initialized. Since the main controller 33 also serves as an initialization means for returning to the determination criterion of the setting, it is convenient because the necessary correction can be given to some extent from the beginning even when the use conditions are different.

Next, a third embodiment of the present invention will be described. The third embodiment is an embodiment of the invention described in claim 6, and further develops a means for independently setting the range of key input determination with respect to the display range of each key in the above-described embodiment to further improve the operational feeling. It is intended to improve the. In the third embodiment, the key input determination range (reference value) is independently set for the display range of each key on the display panel 18 in the second embodiment, as shown in FIGS. 5 and 6, for example. In addition, a plurality (here, double) is set.

The main controller 33 executes the confirmation sequence shown in FIG. 13 instead of the confirmation sequence shown in FIG. 12, and causes the T / P controller 31 to execute the position data collection routine after waiting for the analog touch panel 11 to be pressed. Then, the main controller 33 sets the input coordinates (the pressed position of the analog touch panel 11) obtained by the position data collection routine and the center coordinates of the coordinate range of the key input determination corresponding to the dot of the key displayed on the display panel 18. Whether or not there is a key input on the analog touch panel 11 is determined by detecting a difference and determining whether or not this difference is within the first key input determination range (the range of the primary gate). If it is within the range of the primary gate, the central coordinates of the range of the key input judgment is corrected by the statistical method and updated.

Then, the main controller 33 determines that the difference is the second difference unless the difference is within the range of the primary gate.
It is judged whether or not it is within the range of the key input judgment (range of the secondary gate), and if the difference is not within the range of the secondary gate, the position data of the input coordinate is judged to be invalid. Also,
If the difference is within the range of the secondary gate, the main controller 33 controls the LCD controller 19 to control the LC
Display a request message such as re-input request on D18,
The position data collection sequence and the difference detection sequence are re-executed.

The main controller 33 determines whether or not the difference obtained by the re-execution is within the range of the primary gate, thereby determining whether or not there is a key input on the analog touch panel 11, and the difference is 1 If it is within the range of the next gate, the center position data of the input coordinates is updated by the correction of the above equation by a statistical method, and if the difference is not within the range of the primary gate, the position data of the input coordinate is invalid. judge.

In the above-mentioned embodiment, since there is only one key input judgment range, it can only be judged whether or not the key is pressed. However, in this embodiment, not only the judgment as to whether or not the key is pressed is performed. By determining that the difference is outside the range of the primary gate and within the range of the secondary gate, it can be determined that the key is likely to be pressed. As a result, regardless of the screen design on the operation panel, it is easy to prevent an erroneous operation that occurs when operating a key in a region where the keys are crowded or when the operator touches the key carelessly. This brings out the advantage of the soft key in which the touch panel and the display device are combined.
