Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a function setting device, and more particularly to a function setting device that can use a few switches for various function settings as needed.

<Prior Art> Most devices have a predetermined function set by a switch, and the device performs an operation according to the set function. In the conventional device, one switch is provided for each function, and in order to cause the device to execute a predetermined function, the switch corresponding to the device may be pressed.

<Problems to be Solved by the Invention> By the way, recently, a variety of functions have been installed in in-vehicle audio equipment and the like, and the number of operation switches tends to increase. Since the size of the operation panel is limited in in-vehicle equipment, the switches must be small and densely arranged, making the switch operation difficult and finding the desired switch. Has become difficult.

From the above, it is an object of the present invention to provide a function setting device that does not require a reduction in the size of the switch, and does not require an increase in the number of switches even if the number of functions increases, and is therefore excellent in operability. To do.

<Means for Solving Problems> The present invention is a function setting device that sets a predetermined function by a switch and executes an operation according to the set function. The function setting device includes a plurality of operation switches. A state switching means for setting the function assignable state and the function settable state, a function assigning means for assigning a function to each operation switch in the function assignable state, and a correspondence relationship between each operation switch and the function assigned to the switch. It is configured to have a memory for storing and a control unit for identifying a function corresponding to the operation switch operated in the function settable state based on the correspondence relationship and executing the function.

<Function> The function allocating means is composed of a counter, a switch for updating the count value of the counter, a display section for displaying the count value of the counter, and a means for enabling the function allocation.
The correspondence between the count value of the counter and the function is stored in advance in the non-volatile memory.

Then, in the function assignable state, the count value of the counter is set to a numerical value corresponding to the function to be assigned to the operation switch, and then the operation switch is pressed. As a result, the correspondence between the pressed operation switch and the count value at that time is registered in the non-volatile memory. Thereafter, by the same operation, the correspondence between all the operation switches and the count value of the counter is registered in the non-volatile memory.

After that, if a predetermined operation switch is pressed in the function settable state, a numerical value corresponding to the pressed operation switch is obtained from the non-volatile memory, then a function corresponding to the numerical value is obtained, and the in-vehicle audio device is operated. To execute the function.

<Embodiment> FIG. 1 is a circuit block diagram of a function setting device according to the present invention, FIG. 2 is an explanatory view of an operation portion of the function setting device when the present invention is applied to an audio device, and FIG. 3 is a function list. is there.

As a function of the vehicle audio equipment, various functions are prepared for the deck, the tuner, and the audio. FIG. 3 is a function list showing an example of such functions. For example, the deck has (1) a programmable music sensor function that is a function of selecting a music of a desired music number, and (2) a predetermined intro section of each music. Music scan function that plays back time and plays the intro of the next song in sequence until a predetermined switch is operated. (3) Dolby B on / off setting function (Dolby is a trademark) (4) Dolby C on / off setting function (5) Repeat function to set repeat playback of desired song (6) Metal function to indicate whether it is a metal tape (7) Memory function to store the tape running position pressed The tuner has, for example, (1) FM / AM selection function, (2) Auto memory function that stores all the radio stations that can be heard (3) Tuning to the next broadcast frequency each time a predetermined switch is operated Seek function, (4) Scan function that tunes to a new next broadcast frequency every predetermined time (5 to 10 seconds), (5) LOCAL / DX function ..... For audio, for example, (1) Mute function that lowers the volume during playback by 20 dB (2) Loudness function that corrects frequency characteristics according to the feeling of small sounds (3) Tone control Change the rising and falling points of the low range Low frequency turnover function (4) Tone control High frequency turnover function that changes the rising and falling points of the high frequency range (5) Tone control function to switch the tone control on / off (6) Cut unnecessary high frequencies High-pass filter function (7) Low-pass filter function that cuts unnecessary low frequencies (8) Treble function that adjusts treble (9) Bus function that adjusts low-pitched sound (10) Balance the volume of left and right channels Let Nsu function ......... and the like.

However, not all such features are typically needed, and the actual features required are limited to the deck, tuner, and audio, respectively. For example, for the deck, a music scan function, a Dolby B on / off function,
Three repeat functions are required, and FM is applied to the tuner.
/ AM switching function, seek function, LOCAL / DX
Three of the functions are required, and in the audio, three of the treble function, the bus function, and the balance function are required.
Others are unnecessary for the time being, or the standard setting is sufficient.

From the above, in the present invention, the operation section of the in-vehicle audio equipment is not provided with operation switches corresponding to all the functions, but the minimum operation switches are provided so that the function of each operation switch can be changed as necessary. .

FIG. 2 (A) shows an example of an operation part (only the part related to the present invention is shown and the other parts are omitted) when the present invention is applied to an on-vehicle audio device, and 11 is related to a deck. A function setting unit, 12 is a tuner-related function setting unit, and 13 is an audio-related function setting unit.
Operation switches (operation keys) 11a to 11c, 12a
.About.12c, 13a to 13c, and display units 11d, 12d,
13d and function assignment keys 11e, 12e, 13e
And buttons 11f, 12f, 13f for setting the functions of the deck, tuner, and audio to the corresponding operation switches. It should be noted that instead of the buttons 11f to 13f, only one button may be provided and used in common.

By the way, the operation keys 11a to 11c, 12a to 12
The functions c, 13a to 13c are assigned to the deck, tuner, and audio by a method described later, but it is necessary to identify which function is assigned to each operation key. Therefore, for example, a cover 20 shown in FIG. 2B is provided, and portions 21a to 21c and 22a of the cover are provided.
22c and 23a to 23c to the operation keys 11a to 11c,
Corresponding to 12a to 12c and 13a to 13c, the function name assigned to each operation key is described in each part, and the cover is attached to the front surface of the operation portion as shown by the dotted line in FIG. 2 (A). In addition, in FIG. 2 (B), reference numeral 24 is a hollow portion.

The function setting operation of the present invention will be described below with reference to FIG. It should be noted that FIG. 1 shows only the portion related to the deck and omits the portions related to the tuner and the audio, but has the same structure. The same parts as those in FIG. 2 are designated by the same reference numerals.

11a to 11c are operation keys, 11d is a display unit for displaying a count value of a counter, which will be described later, 11e is a function assigning key for counting up the count value of the counter, 11f is an assignable assigning function of the deck to the operation keys 11a to 11c Buttons to be brought into a state, 101a to 101e are pulse generation circuits that generate one pulse when each key and button are pressed, and 102 is a JK flip-flop circuit that repeats setting / resetting every time the button 11f is pressed. And each operation key 11a-1 when set (function assignable state)
Functions can be assigned to 1c.

Reference numeral 103 is an AND gate, and 104 is a counter. When the function assignment key 11e is pressed in the function assignable state, the count value n is incremented by one each time it is pressed. When the deck is provided with N functions, it is an N-ary counter.

Reference numeral 105 is an encoder that outputs a code signal corresponding to the pressed operation key, 106 is an OR gate, 107 is an AND gate, and 108 is an RS type that is set when the operation keys 101a to 101c are pressed in the function assignable state. Is a flip-flop circuit, 109 is a processing unit having a microcomputer configuration, and 110 is a cassette deck. Processing unit 1
09 is a processor, ROM, RAM (not shown),
It has a non-volatile memory 109a. The non-volatile memory 109a stores the correspondence between the numerical values and the functions in advance. For example, 1 is programmable music
Sensor function, 2 is music scan function, 3 is Dolby B on / off function, 4 is Dolby C on / off function, 5 is repeat function, 6 is metal function, and 7 is memory function. Stored in advance.

(A) Function Allocation Processing First, the button 11f is operated to set the JK flip-flop circuit 102 so that the function can be allocated. still,
The music scan function is assigned to the operation key 11a, the Dolby B on / off function is assigned to the operation key 11b, and the repeat function is assigned to the operation key 11c.

Next, the function assignment key 11e is repeatedly pressed / released until 2 is displayed on the display unit 11d. Each time the function assignment key 11e is released after being pressed, the counter 104 increments the count value by one.

Operation key 1 when 2 is displayed on the display unit 11d
When 1a is pressed, the flip-flop circuit 108 is set, and the encoder 105 outputs a code signal corresponding to the operation key 11a.

The processor of the processing unit 109 is the flip-flop circuit 10
As soon as 8 is set, the code signal output from the encoder 105 and the count value 2 of the counter are read and stored in the non-volatile memory 109a, and then the flip-flop 108 is reset. As a result, the correspondence between the operation key 11a and the numerical value 2 is determined by the nonvolatile memory 109a.
Will be remembered in.

Similarly, if the operation assignment key 11e is operated to set the count value of the counter 104 to 3 and then the operation key 11b is pressed, the correspondence between the operation key 11b and the numerical value 3 is stored in the non-volatile memory 109a, and the function is also stored. After operating the allocation key 11e to set the count value of the counter to 5, the operation key 11c
If is pressed, the operation key 11c is added to the nonvolatile memory 109a.
Then, the correspondence relationship between and is stored.

As described above, when the correspondence relations of all the operation keys 11a to 11c and the numerical values are registered, the button 11f is pressed to reset the JK flip-flop circuit 102 to make the function setting possible.

(B) Function setting process When the operation key 11a is pressed in the function setting enabled state, a code indicating the operation key 11a is input to the processing unit 109, whereby the processor of the processing unit 109 causes a numerical value corresponding to the operation key 11a. 2 is read from the non-volatile memory 109a, and then the function (music scan function) corresponding to the numerical value 2 is read from the non-volatile memory and input to the cassette deck 110, and the cassette deck is executed to execute the music scan function. , If the operation key 11b or 11c is pressed, the numerical value 3 or 5 corresponding to the operation key 11b or 11c
Is read from the non-volatile memory 109a, then the function (Dolby B on / off function or repeat function) corresponding to the numerical value 3 or 5 is read, and the cassette deck 110 is instructed to execute these functions. It should be noted that each time the operation key 11b is operated, it is switched from Dolby ON to OFF or from OFF to ON.

In the above description, the function set for each operation key is identified using the cover 20, but it is also possible to provide a display element near each operation key and display the function name on the element.

<Effects of Device> As described above, according to the present invention, a plurality of operation switches (operation keys), a state switching means for setting a function assignable state and a function settable state, and each operation switch in the function assignable state. A function assigning means for assigning a function to each of the switches, a memory for storing the correspondence between each operation switch and the function assigned to the switch, and a function corresponding to the operation switch operated in the function settable state based on the correspondence. Since the function setting device is configured with the control unit that identifies and executes the function, it is possible to provide a minimum number of switches and assign a predetermined function to each switch as needed, and accordingly, correspond to each function. Since it is not necessary to provide switches at a ratio of 1: 1, it is not necessary to make the switches compact, and it is not necessary to arrange switches in a dense manner. Easy operation and cost reduction.
