Description

TECHNICAL FIELD The present invention relates to a vehicle-mounted electronic device used as a tuner deck with a clock, a car audio device, or the like.

[Conventional technology]

As one of tuner / deck devices with a clock provided in a vehicle such as an automobile, the one shown in FIG. 5 is conventionally known.

The device shown in this figure has a clock function, a tuner function, and a tape deck function. On its front panel (operation panel) 21, a cassette tape insertion slot 22 and an indicator are provided.
23 and various operation keys 1a to 17a are provided.

In this case, the various keys 1a to 17a are operated in the tape mode, the tuner mode and the clock mode as shown in the table of FIG. Different functions are assigned to the keys 1a to 17a, respectively, so that the keys 1a to 17a are effectively used.

[Problems to be solved by the invention]

By the way, in such a conventional tuner deck device with a clock, a large number of keys 1a to 17 are provided on the operation surface panel 21.
Although a is provided, it may be a meaningless key depending on the mode.

(B) For example, in tape mode, keys 2a, 6a, 8
Since no function is assigned to a, 10a, 11a, 13a, 15a-17a, pressing each of these keys 2a-17a in this mode will have no effect. Further, in this mode, the key 1a to which the FF function is assigned, the key 3a to which the REW function is assigned, and the like are invalid during fast-forwarding and rewinding.

(B) In the tuner mode, since the function is not assigned to the key 9a, even if this key 9a is pressed, this is invalid. Also, in this mode, key 4a
Although the eject function is assigned to, the eject function is used only when the pack is set, so that the key 9a becomes invalid when the eject is completed.

(C) Furthermore, in clock mode, keys 2a, 5a-10
Since no function is assigned to a, 12a to 17a, these respective keys 2a, 5a to 10a, 12a to 17a are disabled.

When the tuner / deck device with a clock is used, the device cannot be operated properly unless the keys 1a to 17a are properly used.

In view of the above circumstances, the present invention allows the device to operate properly by operating the key with a certain degree of accuracy without performing an accurate key operation, thereby performing a blind touch of the key. The purpose is to provide an in-vehicle electronic device that can be used.

[Means for solving problems]

In order to solve the above problems, the on-vehicle electronic device according to the present invention is an on-vehicle electronic device that is mounted and used in a vehicle. It is characterized in that it includes a control unit that is handled as a group and an electronic device unit that is controlled by this control unit.

〔Example〕

FIG. 1 is a block diagram showing an embodiment of an on-vehicle electronic device according to the present invention.

The vehicle-mounted electronic device shown in this figure has a clock function, a tuner function, and a tape deck function. A cassette tape insertion opening 32 is provided on a front panel (operation panel) 31 thereof.
, A display 33, and various operation keys 1b to 16b are provided.

In this case, each key 1b to 16b is assigned a function for each mode as shown in the table of FIG. further,
These keys 1b to 16b are divided into groups A, B, C and D.

In addition, each of these keys 1b ...
An electronic part controlled by 16b is provided.

As shown in FIG. 3, this electronic unit is an operation unit that determines the on / off state of each of the keys 1b to 16b and generates operation data.
39, a control unit 40 (for example, a microprocessor) that processes the output of the operation unit 39, and when the control unit 40 outputs display data, the display unit 33 captures the display data to generate a drive signal and the display unit 33 Controlled by a drive circuit 41 for displaying various data above, a radio section 42 controlled by a radio control signal output from the control section 40, and a tape player control signal output from the control section 40. The tape player unit 43 and the keys 1b to
It operates as described below based on the output of 16b.

First, if this on-vehicle electronic device is in the tape mode and is in the fast-forwarding operation (FF operation) at this time, the groups A to D are respectively wound as shown in FIG. 4 (A). The return function (REW function), eject function (EJECT function), play function (PLAY function), and cue on / off function (MS ON / OFF function) are assigned.

Therefore, in this case, the keys 1b and 2b forming the group A
If any of these is pressed, the control unit 40 outputs a REW signal to the tape player unit 43, and the tape player unit 43
To rewind. Similarly, during this fast-forward operation, when any of the keys 3b to 6b forming the group B is pressed, or the key 7b forming the group C,
When either 8b is pressed, the control section 40 generates an EJECT signal and a PLAY signal, respectively, and causes the tape player section 43 to perform an eject operation and a play operation. Further, in this case, when any of the keys 9b to 16b forming the group D is pressed, the control unit 40 generates an MS signal to
The player section 43 is set to the cueable state.

If the on-vehicle electronic device is set to the tape mode and is in the rewinding operation (REW operation) at this time, the groups A to D are respectively fast-forwarded as shown in FIG. 4 (B). Function (FF function), eject function (EJECT function), play function (PLAY function), cue on / off function (MS ON / OFF function) are assigned.

Then, when any of the keys 1b to 16b is pressed, the control unit 40 determines which group the pressed key belongs to, and the operation of the tape player unit 43 based on the determination result. Controlled.

If this on-vehicle electronic device is set to the tape mode and is in the play operation (PLAY operation) at this time, as shown in FIG. ) And the rewind function (REW function) are assigned, and the eject function (EJ
The ECT function) and the pause function (PAUSE function) are assigned, and the group C is assigned the program function (PROG function) and the audio control function. Similarly, at the time of this play operation, the cue ON / OFF function (MS ON / OFF function) is assigned to the group D.

Then, when any one of the keys 1b to 16b is pressed, the control unit 40 determines what function is currently assigned to the pressed key, and the tape player unit 43 based on this determination result. Is controlled.

Also, when the vehicle-mounted electronic device is in the tuner mode or the clock mode, the keys 1b to
When any of 16b is pressed, by the control unit 40,
Now it is determined which group the pressed key belongs to,
The operation of the tape player unit 43 is controlled based on this determination result.

Thus, in this embodiment, each key 1b to 16b is grouped, and when a key in each group is pressed,
Since the function assigned to this group is executed, when the user operates a key, the correct reaction can be obtained even if the user operates it with a certain sense of location (for example, the sense that there is a key around this area). be able to.

In addition, regarding the operation to the place where the keys are concentrated,
It is possible to facilitate a fumbling operation and perform a more reliable and quick key operation.

In addition, it is possible to improve safety when the driver operates.

In addition, in the above-described embodiment, the keys 1b to 16b are not illuminated, but a color lamp or the like is arranged on the back surface of each of the keys 1b to 16b, and keys having the same function are colored in the back It may be illuminated.

Further, in the above-described embodiment, the audio control function is assigned to one key 8b, but the audio control function is assigned to two or more keys, and the function, for example, volume, bass, treble, fender, etc. It is also possible to give priority to the size of each of the control functions and the Dolby on / off function according to their importance or frequency of use.

〔The invention's effect〕

As described above, according to the present invention, it is possible to operate the device correctly by operating the keys with a certain degree of accuracy without performing an accurate key operation, and thereby to perform the brand touch of the key. be able to.
