DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In this embodiment, as shown in FIG.
20. Eight audio signals are input to the DSP 20, and the DSP 20 controls the acoustic characteristics, for example, the volume level and the frequency characteristics of the respective signals in eight channels provided therein. Then, the controlled signals of the respective channels are mixed in a predetermined state and output as a right signal R and a left signal L.

Each channel is provided with an attenuator, an equalizer, a filter, and the like for adjusting acoustic characteristics, and these characteristics are controlled based on acoustic control information supplied from the CPU 22.

The CPU 22 stores the sound control information in each of the operation units 24 of the operation unit provided for each channel.
Generated according to the operation of. Further, the CPU 22 causes the touch display 28 to display characteristics such as an equalizer and a filter, frequency characteristics of an input signal and an output signal, and the like via the driving unit 26.

The display instruction is sent to the CPU 22 by a switch unit 30 provided on the touch display 28.
Is given according to the operation of.

The touch display 28 can display a parent screen as shown in FIG. 1 (b) and a child screen as shown in FIG. 1 (e). And a display 34 of each acoustic characteristic name such as an attenuator characteristic, an equalizer characteristic, and a filter characteristic are displayed. When one of the channel name displays 32 is touched by a finger, the switch unit 30 instructs the CPU 22 to display the same. When the name of the touched channel is specified and the finger touches any one of the display 34 of each property name, the touched property name becomes C
In response to the instruction from the PU 20, the CPU 22 causes the touch display 28 to be displayed on the touch display 28
A child screen as shown in (e) is displayed.

On this sub-screen, a display showing the name of the selected channel (two channels in this example) and the selected characteristic (equalizer characteristic in this example) is made, and the contents of the selected characteristic are specifically displayed. It is displayed as a graphic. Further, a switch display 36 for switching the display from the child screen to the parent screen is also displayed. When the switch display 36 is touched by a finger, the switch unit 30 gives a command for switching display to the main screen to the CPU 22, and the CPU 12 causes the touch display 28 to display the main screen via the drive unit 26.

When an instruction to switch the display from the parent screen shown in FIG. 1B to the child screen shown in FIG. 1E is given, FIG.
As shown in (d), the screen is gradually switched from the central part of the parent screen to the child screen, and finally all of the screen becomes the child screen.

Conversely, when an instruction to switch the display from the child screen to the parent screen is given, the state shown in FIG.
As shown in (c), the screen is gradually switched from the peripheral portion of the child screen to the parent screen, and finally all of the screen is switched to the parent screen.

In order to perform such screen switching, the CP
U22 operates as shown in the flowchart of FIG. That is, first, a control signal is supplied to the drive unit 26 to display a parent screen as shown in FIG. 1B (step S2). Next, it is determined whether the child screen has been selected, that is, whether one of the channel name displays 32 and the characteristic name display 34 has been touched by a finger (step S4). If not, step S4 is repeated until it is touched. Therefore, the display on the touch display 28 remains the parent screen.

When the child screen is selected, the display is gradually switched from the central part of the screen to the child screen (step S6).
The switching to the child screen is performed, for example, when the screen size is as shown in FIG.
Assuming that the size is 640 × 480 dots as shown in (a), first, as shown in FIG.
A portion of × 48 dots is displayed as a sub-screen, and after approximately 50 msec, the driving portion 26 is provided so that a portion of 128 × 96 dots becomes a sub-screen as shown in FIG. The contents of the display memory are rewritten. Hereinafter, similarly, every 50 ms, 64 dots horizontally and 4 dots vertically.
The contents of the display memory are rewritten so that the size of the child screen increases by 8 dots. In this way, the screen can be completely switched to the child screen in about 0.5 seconds.

After the switching to the child screen is completed,
Whether the main screen image has been selected, that is, the changeover switch display 3
It is determined whether a finger has touched 6 (step S8). If not, step S8 is repeated until it is touched. Therefore, the display of the child screen is maintained.

When the contact is made, the display is gradually switched from the peripheral portion of the child screen to the parent screen (step S).
10). This switching is opposite to the switching of the display from the main screen to the child screen. First, a portion of 64 × 48 dots in the peripheral portion is displayed on the main screen, and after a lapse of about 50 msec, the 128 × dot of the peripheral portion is displayed.
The contents of the display memory in the drive unit 26 are rewritten so that the 96 dot portion becomes the main screen. Hereinafter, similarly, 50
Every time m seconds elapse, the display area of the parent screen increases by 64 × 48 dots from the peripheral portion, and after 0.5 seconds, the display is completely switched to the parent screen. Following this step S10,
Step S4 is executed again.

In the above embodiment, the touch display 2
Although 8 is used, a normal display device and function keys can be used instead. In the above embodiment, when switching from the main screen to the child screen,
The screen was gradually switched from the central part, and when switching from the child screen to the parent screen, the screen was gradually switched from the peripheral part. Conversely, when switching from the parent screen to the child screen, the screen was switched from the peripheral part and the child screen was switched. When switching from screen to parent screen,
The switching may be performed from the center.

Further, in the above-described embodiment, switching between two parent and child screens has been described. However, the present invention is not limited to this, and switching between a plurality of screens such as a parent, a child, and a grandchild can also be performed. For example, in the case of an audio mixer device, since each of the above channels is provided in the input channel unit, the group unit, the main unit, and the like, a screen for selecting any of these units is used as a main screen, and FIG. The channel and characteristic selection screen shown in (b) may be used as the child screen, and the screen showing the specific acoustic characteristics of the selected channel shown in FIG. 1 (e) may be used as the grandchild screen.
When switching to three or more screens in this way, for example, when switching from the parent to the child screen, when switching the screen from a position slightly left from the center of the screen, and when switching from the child screen to the grandchild screen, As in the case of switching from a position slightly to the right of the center, it may be possible to know which screen is being switched to which screen by the position at which the screen switching is started.

[0022]

As is evident from the foregoing description, according to the present invention, in a state of displaying the first screen type of the plurality of processing are displayed on the display means, a plurality of processing by switching command means
When a command to switch to the second screen displaying the selected processing content is given, the second screen gradually appears from the first position of the display means . When a switching command is given by the switching command instructing means in the display state of the second screen, the display
The first screen gradually appears from the second position of the means . Therefore, without knowing which screen is the first screen or the second screen, the first or the first screen is determined from the position where the screen appears.
You can see if the display has been switched to the second screen ,
Even when a person other than the person performing the switching operation is looking at the screen, it can be easily determined whether the screen has been switched to the first or second screen, and the person performing the switching operation can also see from the position where the switching screen appears. It is easy to determine whether the operation performed by the user is wrong.
