FIG. 1 shows an embodiment in which the present invention is applied to a digital audio mixer. This embodiment has a DSP (digital signal processing device) 6 which functions as a main body of a digital audio mixer. This DSP6
Are programmed to function as input channel units, group channel units, main channel units, etc. A plurality of each input channel unit, group channel unit, and main channel unit are provided.

Each input channel unit is connected to, for example, any one of the first to 256th input terminals, and the level adjustment and frequency characteristic adjustment of the digital audio signal supplied from the connected input terminal are performed. Etc. are adjusted and output.

Each group channel unit is connected to an arbitrary one of the input channel units, and various adjustments such as level adjustment and frequency characteristic adjustment of the digital audio signal supplied from the connected input channel unit are performed. Go and print.

Each main channel unit is connected to an arbitrary one of the group channel units, and various adjustments such as level adjustment and frequency characteristic adjustment of the digital audio signals respectively supplied from the connected group channel units are performed. Go and print.

The connection between each input channel unit and each group channel unit and the connection between each group channel unit and each main channel unit are made by instructions from the CPU 8.

The CPU 8 also adjusts the level and frequency characteristics of each input channel unit, each group channel unit and main channel unit.
It is done according to the instructions from. The CPU 8 gives these instructions in accordance with the operation of an operator (not shown).

In addition to this, the CPU 8 is a data storage means,
For example, it has a memory 10 in which the states of the respective input terminals are stored in a tabular form as shown in FIG. This memory 10 has 256 records corresponding to the respective input terminals, and each record is composed of 4 fields.

The first field of each record is
Identification information indicating which input terminal corresponds, for example, an input number (INPUT NO.) Field in which an input number is stored. In the input number field of the record corresponding to the first input terminal, the numerical value 1 Numerical value 2 is entered in the input number field of the record corresponding to the 2 input terminals ...
A numerical value 256 is stored in the input number field of the record corresponding to the 6 input terminals. That is, consecutive numerical values are sequentially stored in each input number field.

The second field is a NAME field in which the name given by the operator is stored in the corresponding input terminal. The third field is a phantom (PTM) field that indicates whether or not power, that is, phantom power is being supplied to the condenser microphone from the audio mixer side when the condenser microphone is connected to the corresponding input terminal. When the phantom power is supplied, the data of ON is stored, and when the power is not supplied, no data is stored. The fourth field is
In the specified level (PAD) field that indicates the specified level of the signal output from the corresponding input terminal, the level of the level adjuster attached to the input terminal is adjusted according to this value.

Each of these records is displayed on the screen of the display means, for example, the display device 10, and the total number of records is 25.
Since there are as many as 6, all the records cannot be displayed on the screen at the same time, and a part of them, that is, 8 records in this embodiment, are displayed on the screen of the display device 12 at the same time. On this screen, eight records in which each field is displayed in a line along the horizontal direction of the screen are displayed in a line in the vertical direction of the screen. That is, it is displayed in a table format.

This display is, for example, the contents of each field from a record including an input number field having a value that matches the value of a movement signal described later to a predetermined number following this record, in this case, seven records. Is written in the video RAM (not shown) by the CPU 8 so as to be displayed in the state shown in FIG. That is, the CPU 8 functions as display control means.

When the value of the moving signal is changed while the record is displayed in this way, the contents written to the video RAM are changed from the record having the input number corresponding to the new value of the moving signal to this. It is changed to a predetermined number of subsequent records.

For example, as shown in FIG. 1, in the state where the value of the movement signal is 136 and the contents of the respective records whose input numbers are 136 to 143 are displayed in order from the top to the bottom of the screen, The value of the movement signal is 136 to 1 larger 137
Is changed to a state in which records with input numbers 137 to 144 are sequentially displayed from the top to the bottom of the screen.

On the contrary, when the value of the movement signal is changed from 136 to 135, the records are sequentially displayed from the top to the bottom of the screen with input numbers 135 to 142.

That is, according to the value of the movement signal, the display device 1
The screen No. 2 is scrolled vertically. The above description is for the case where the value of the movement signal increases / decreases by 1. However, even when the value of the movement signal greatly increases / decreases, it is continued from the record having the input number corresponding to the value of the movement signal. The display is changed to a predetermined number of records.

Such a movement signal is generated by the movement signal generating means 14. This movement signal generation means 14
Includes a manipulator 16, and the manipulator 16 is a display device 1
2 has a knob 20 that slides between a base point formed at the upper end of the slide path 18 that coincides with the vertical direction of the screen and an end point formed at the lower end, and the amount of movement of this knob 20 from the base point is The knob position detector 22 detects it, generates a movement signal, and supplies it to the CPU 8. In accordance with this movement signal, the screen of the display device 12 is scrolled as described above.

When the knob 20 is located at the base point, the position detector 22 produces a movement signal having a value of 0, and when the knob is located at the end point, the position detector 22 produces a movement signal having a value of 256. To do. When there is a knob between the base point and the end point, a movement signal having a value between 0 and 256 is generated in proportion to the amount of movement of the knob from the base point. Further, scales 24 are provided at equal intervals from the base point to the end point along the slide path 18 of the operator 16.

Therefore, when the knob 20 is made to coincide with the position of the value of 136 on the scale 24 as shown in FIG. 1, the record of the input number 136 is set as the head and the input number 143 is set.
The records up to the input number 207 are displayed on the display device 12. However, when the knob 20 is slid to the position of 200 on the scale 24 in this state, the records of the input number 200 and the input number 207 are set to the head. Are displayed in order.

Since the sliding of the knob is performed only between the base point and the end point in this way, as compared with the case of using the rotary encoder as long as the knob is rotated, as in the rotary encoder. Then, it is possible to recognize which part is scrolling at the position of the knob, and scrolling is easy. Further, since the sliding direction of the knob 20 of the operator and the scrolling direction of the screen both coincide with the vertical direction, the scrolling operation becomes easier, and the scale 24 is provided along the sliding path 18. Therefore, it is even easier to scroll to the desired record.

Regarding the display of the screen of the display device 12, a movement signal is further supplied to the CPU 8 from a keyboard 26 as another movement signal generating means. This movement signal can be used for scrolling the screen as with the manipulator 16, or, for example, from the state in which the records of the input numbers 1 to 8 are displayed, the input numbers 9 to 16 are input.
It is also possible to perform so-called page turning, in which the record of is displayed. In the case of this page turning, the movement signal represents, for example, the input number of the record displayed at the top of the screen in the page turned state.

In this way, when scrolling or page turning is performed by the movement signal from the keyboard 26,
This movement signal is supplied from the CPU 8 to the driving means, for example, the motor drive unit 28. Motor drive unit 28
Causes the knob 20 to slide to a position corresponding to the value of the movement signal. If the knob 20 is not moved to the position corresponding to the movement signal from the keyboard 26 as described above, the knob 20 is displayed at the top of the screen when the user tries to scroll the screen by operating the knob 20 next time. The input number of the current record does not correspond to the position of knob 20,
This is because the knob 20 makes scrolling difficult.

In the above embodiment, the screen of the display device 12 was scrolled in the vertical direction. However, as shown in FIG. 3, for example, each field of the record is displayed along the vertical direction of the screen, and the scroll is performed on the screen. It may be performed along the horizontal direction.

In this case, the operator 16 also has its knob 20.
If the slider slides along the horizontal direction, the scroll direction and the sliding direction of the knob 20 coincide with each other, which facilitates the scroll operation.

More specifically, as shown in FIG. 3, when the record of the input number 22 is displayed at the left end of the screen, when the knob 20 is moved to the position 50 of the scale 24, the left end of the screen is displayed. The record with the input number 50 is displayed,
Records with input numbers 51, 52, ... 57 may be displayed in order on the right side of this.

In the above embodiment, the movement signal represents the value of the input number of the record displayed at the top of the screen in the case of FIG. 1 and the record at the leftmost end of the screen in the case of FIG. In the case of FIG. 1, the input number of the record displayed at the bottom of the screen is shown, and in the case of FIG. 3, the input number of the record at the rightmost end of the screen is shown. May represent the value of. In that case, the CPU 8 may display a predetermined number of records, for example, seven records from the record having the input number represented by the value of the movement signal, followed by the record having the sequentially smaller input number.

Further, in the case of FIG. 1, for example, the movement signal may represent the input number of a record in the middle of each displayed record. In this case, a predetermined number of records whose value is smaller by 1 than the input number corresponding to the movement signal and a predetermined number of records whose value is larger by 1 than the input number corresponding to the movement signal are displayed. Even if the value of the movement signal is changed, a predetermined number of records whose value is smaller by 1 than the input number corresponding to the changed movement signal, and the value is larger than the input number corresponding to the movement signal. It is sufficient to display a predetermined number of records in which is incremented by 1.

Further, in the above embodiment, when the screen is scrolled upward, the knob 20 is operated downward, and when the screen is scrolled downward, the knob 20 is operated upward, but the screen is inverted upward. Knob 2 when scrolling to
If you operate 0 upward and scroll the screen downward,
The knob 20 may be operated downward.

In the above embodiment, a plurality of records are simultaneously displayed in a table format, but for example, in a card format in which each field is not continuously displayed horizontally or vertically, only one record corresponding to a movement signal is displayed. Alternatively, when the value of the movement signal is changed, only the record having the input number corresponding to the value may be displayed.

Further, a plurality of consecutive cards are displayed in the card format, and the value of the moving signal corresponding to the card (the one having the smallest input number) of the moving signal values is displayed. When is changed, a predetermined number of cards whose input numbers are incremented by 1 may be displayed from the card having the input number corresponding to the changed movement signal value.

Similarly, for example, when a plurality of consecutive cards are displayed and the value of the movement signal corresponding to the card at the end (the card with the largest input number) is changed,
From the card having the input number corresponding to the changed value of the movement signal, a predetermined number of cards having an input number smaller by 1 may be displayed.

Further, in the above-described embodiment, the operation element 16 is of a so-called slide type in which the knob 20 slides along the linear slide path 18 from the base point to the end point.
The sliding path 18 from the base point to the end point is a circular arc,
It is also possible to use a so-called rotary volume.

[0050]

As described above, according to the first aspect of the invention, each record stored in the data storage means is
At least the movement signal to be displayed is generated by the movement signal generation means having a knob movable from the base point to the end point in proportion to the movement amount from the base point of the knob, so that the identification code can be largely determined from the currently displayed record. Even when different items are displayed, it is possible to know how much the knob should be operated from the position of the knob, that is, since it is easy to have a correspondence relationship between the identification code and the position of the knob, such a large identification code Even different records can be displayed instantly.

According to the second aspect of the present invention, the records to be displayed are not limited to those corresponding to the movement signal, but the identification information stored in the identification field is continuous by a predetermined number. Since a plurality of records including a plurality of identification fields are displayed, for example, in addition to a desired record, a record in the front, rear, or front-rear direction of the record can be instantly displayed according to the operation of the knob of the movement signal generation means. Can be displayed.

According to the third aspect of the present invention, the knob of the movement signal generating means is formed so as to be movable along one of the horizontal and vertical directions of the screen of the display means, and the display control means controls each record. Since the display is displayed along one of the horizontal and vertical directions of the screen, the direction in which the screen is scrolled corresponds to the moving direction of the knob. Therefore,
Easy to scroll.

According to the fourth aspect of the invention, since the movement signal generating means has a scale corresponding to each piece of identification information along the movement direction of the knob from the base point of movement of the knob to the end point, which identification information is used? Even when a corresponding movement signal is generated, it is possible to more easily display the desired record by referring to the scale.

According to the invention described in claim 5, according to the movement signal of the movement signal generating means different from the movement signal generating means,
