<Problems to be Solved by the Invention> By the way, in an on-vehicle audio device with an operation panel opening / closing function, when an accessory is off (when ACC is off)
The operation panel is fully closed. For this reason, when the accessory is turned on (ACC-ON), it is necessary to reset the angle position so that the operation panel is easy to see and the operability is good, which is a troublesome problem.

Further, in a structure in which the recording medium insertion / ejection port is hidden by the operation panel, it is necessary to fully open the operation panel in order to eject a recording medium such as a cassette or a CD. For this reason, even if the operation panel is set to an opening angle that is easy to see and has good operability, the operation panel must be set to the desired opening angle position again each time the recording medium is ejected / inserted, which is troublesome. There is a problem that becomes.

From the above, an object of the present invention is to provide an electronic device with an operation panel capable of automatically rotating the operation panel to a desired opening angle position at the time of ACC-ON or ejecting / inserting a recording medium. Is.

The operation panel is automatically opened to the stored opening angle position (memory angle) regardless of the presence or absence of the pack, and (iv) if the operation panel is half open, it will be fully opened regardless of the state of the pack. .

3 to 6 are flowcharts of the operation panel opening / closing control according to the present invention. FIG. 3 is a flowchart of the opening / closing control when the open / close key is turned on, and FIG. 4 is an eject / reload key on operation. Flow chart of opening and closing control when
FIG. 5 is a flow chart of the opening / closing control when the ACC is on / off, and FIG. 6 is a flow chart of the opening / closing control when the pack is inserted. The opening / closing control of the operation panel of the present invention will be described below with reference to these flowcharts.

(a) Open / close key ON operation It is checked whether the open / close key 101a-2 is turned on (step 201). If “NO”, the flag F (initial value “0”) is “0”. A check is made (step 202), and the processes of steps 201 and 202 are executed until it is turned on.

When the open / close key is turned on, the control microcomputer 102 checks whether it is fully closed or fully open (steps 203 and 204). It should be noted that fully closed and fully opened can be determined by checking the on / off states of the fully closed limit switch 108a and the fully open limit switch 108b.

If not fully closed or fully open (half open state), flag F = "
It is checked whether it is 0 ". At first, since F =" 0 ", it becomes" YES ", and" 1 "→ F, and at the same time, an open signal NRD is output to the motor drive circuit 105 to open / close the motor
4 is rotated forward to rotate the operation panel 101b in the opening direction (steps 205 to 207).

Then, check if it is fully opened (step 208),
If "NO", it is checked whether the open / close key is turned on again (step 201), and if it is not turned on, it is checked whether F = "0" (step 20).
2) Since F = “1”, the process jumps to step 207 to continue the open control.

Thereafter, if the open / close key is not turned on, the operation panel is finally fully opened, and "YES" is determined in step 208. As a result, the control microcomputer 102 stops the rotation command to the motor drive circuit 105, stops the opening / closing motor 104 (step 209), and ends the process.

On the other hand, if the open / close key is turned on again during the opening operation, “YES” is determined in the step 201, and the processes of the step 203 and the subsequent steps are performed. In this case, since it is not fully closed or fully opened, "NO" in steps 203 and 204.
Then, in step 205, a check of F = “0” is performed. This time, in step 206, F = ”
Since it is 1 ”, it is“ NO ”. As a result, the control microcomputer 102 sets “0” → F and
The opening angle A at that time is set as A _M , and the opening angle storage unit 102
It is stored in c (steps 210 and 211), and thereafter, the rotation of the operation panel is stopped in step 209. That is,
When the open / close key is turned on again before the operation panel is fully opened, the operation panel immediately stops and the opening angle, which is the stop position, is stored in the memory (memory angle).

On the other hand, if the operation panel 101b is in the fully closed state when the open / close key is first turned on, the result is "YES" in step 203, and the control microcomputer 102 outputs a forward rotation command to the motor drive circuit to open / close the motor. The operation panel 101b is rotated in the forward direction by rotating 104, and the operation panel 101b is rotated from the fully closed direction to the fully open direction (step 212).

Further, the control microcomputer 102, while rotating the operation panel, checks whether the current rotation angle A becomes equal to the opening angle A _M stored in the opening angle storage unit 102c and whether it is fully opened (steps 213 and 214). ).
If the opening angle A _M is stored, A
= A _M , and if it is not stored, A = A _M never holds.

If "NO" in steps 213 and 214, it is checked whether the open / close key has been turned on again, and if "NO", the processes from step 212 onward are repeated. If the open / close key is not turned on again, finally in step 213 or 214, "Y
"ES" is reached, and the operation is stopped at the memory angle position or the fully open position (step 216), and the process ends.

However, when the open / close key is turned on again, "YES" is determined in step 215, and the control microcomputer 102 stores the opening angle A at that time as A _M in the opening angle storage unit 102c (step 217).
Thereafter, in step 216, the rotation of the operation panel is stopped. That is, open / open before the operation panel is fully opened.
When the close key is turned on again, the operation panel is immediately stopped and the opening angle, which is the stop position, is stored in the memory (A → A _M ).

On the other hand, if the operation panel 101b is in the fully open state when the open / close key is first turned on, the result is "YES" in step 204, and the control microcomputer 102 outputs a reverse rotation command to the motor drive circuit to turn on the opening / closing motor 104. Then, the operation panel 101b is rotated from fully open to fully closed (step 218).
It is checked whether it is fully closed (step 219).

If “NO” in step 219, open /
Check if the close key has been turned on again, and
If it is "O", the processes from step 218 are repeated.
If the open / close key is not turned on again, the result in step 219 is “YES”, the operation is stopped at the fully closed position (step 209), and the process ends.

However, when the open / close key is turned on again, "YES" is determined in step 220, the control microcomputer 102 jumps to step 204, and repeats the subsequent processing. That is, thereafter, the same processing as the above-described processing in the case of half-opening (when it is neither fully closed nor fully opened) is repeated.

As described above, when the open / close key is turned on during the opening operation, the opening angle A of the operation panel at that time is stored as A _M (memory angle). Then, after that, when the operation panel is fully opened or fully closed from the stored opening angle position, the operation panel can be automatically opened to the opening angle position A _M by a predetermined operation.

(b) Eject / reload key on operation For the purpose of downsizing, in an audio device configured to cover the recording medium insertion / ejection opening such as a cassette with an openable / closable operation panel, when setting the recording medium on the deck It is necessary to fully open the operation panel to expose the recording medium inserting / ejecting port, and insert or eject the recording medium from the inserting / ejecting port. Therefore, in the present invention, the operation panel 101 is operated by turning on the eject / reload key 101a-1.
b is automatically opened and closed, and the loading / unloading operation can be performed.

Hereinafter, such processing will be described with reference to FIG.

When the eject / reload key 101a-1 is turned on (step 301), the control microcomputer 102
Checks if the pack is fully open (step 302), and if not fully open (step 3)
03).

If the pack is not inside, the ON operation of the eject / reload key is ignored and the processing ends immediately. If the pack is inside, the opening / closing motor 104 is normally rotated to fully open it (step 304), and then the loading mechanism. 107 is performed to eject the pack (step 305). Further, in the half-packed state (the state in which the pack is not taken out after the eject), the control microcomputer 102 normally rotates the opening / closing motor 104 to fully open the operation panel 101b (step 306), and then loads the loading mechanism to pack. Again (step 307), and after the loading is completed, the opening / closing motor 104 is rotated in the reverse direction to operate the operation panel 10.
Rotate 1b from fully open to fully closed (step 30).
8).

While rotating the operation panel, the control microcomputer 102 checks whether the current rotation angle A is equal to the opening angle A _M stored in the opening angle storage unit 102c or is fully closed (steps 309 and 310). Finally, the memory angle position or the fully closed position is reached and the process is stopped (step 311), and the process ends.

On the other hand, if the operation panel is in the fully open state in step 302, the state of the pack is checked (step 31
2).

If there is no pack, the eject / reload key ON operation is ignored, and if a pack is present, the loading mechanism 107 is used to eject the pack (step 313). repeat.

That is, when the eject / reload key is turned on, it is ignored if the pack is not inside, and if there is, it is ejected after it is in the fully open state, and if it is in the half pack state, it is reloaded after full opening, and then the operation panel memory Rotate to the angle position or the fully closed position.

(c) Accessory switch on / off operation In the present invention, the operation panel is fully closed when the accessory switch (ACC switch) is turned off by the ignition key operation of the automobile, and is opened before the full close when the ACC switch is turned on. The operation panel is rotated to the position. FIG. 5 is a flow chart of such processing.

When the ACC switch is turned on (step 401), the control microcomputer 102 normally rotates the opening / closing motor 104 to rotate the operation panel until the current angle A becomes equal to the memory angle A _M (steps 402, 403), and A = A. When it reaches _M , the operation panel is stopped (step 404) and the operation panel is automatically opened to the opening angle position immediately before the ACC switch is turned off.

On the other hand, when the ACC switch is turned off (step 40)
5) Then, the control microcomputer 102 stores the opening angle A of the operation panel at that time as A _M in the storage unit 102c (step 406) and then determines the pack state (step 407). 104 is reversed and the operation panel is fully closed to end the processing (step 408). On the other hand, in the half-pack state, the pack is reloaded after being fully opened, and then fully closed to complete the processing (steps 409, 410, 408).

(d) Processing during pack insertion (Fig. 6) With a structure in which the recording medium insertion / ejection port is hidden by the operation panel, the operation panel must be fully opened to eject the pack (recording medium). For this reason, even if the operation panel is set to an easy-to-see and easy-to-use opening angle, it is not necessary to set the operation panel to the desired opening angle position again when ejecting the pack and then inserting a new pack. It must be troublesome. Therefore, in the present invention, when the pack is inserted, the operation panel is automatically opened to the position that was open before the ejection. still,
Set the pack in the insert / discharge port in the half-pack state,
The operation panel can be opened to the memory angle position by operating the eject / reload key, and the processing in that case has already been described with reference to FIG. The process of inserting the pack will be described below with reference to the flowchart of FIG.

When the pack is inserted into the insertion / discharge port (step 501) and pushed into the deck, the control microcomputer 102 causes the loading mechanism 107 to load the pack onto the deck (step 502).

When loading is completed, control microcomputer 102
Rotates the open / close motor 104 in the reverse direction to rotate the operation panel in the fully closing direction (step 503). In parallel with this, the current rotation angle A becomes equal to the opening angle A _M stored in the opening angle storage unit 102c. It is checked whether or not it is closed or fully closed (steps 504 and 505).

If the opening angle A _M is stored, A = A _M before fully closing
Is stopped at the memory angle position, and if A _M is not stored, the operation is stopped at the fully closed position (step 506), and the process ends.

In the above description, the opening angle of the operation panel is monitored by counting up / down the clock pulse, but it may be configured by another method.

Also, although the explanation is omitted, when the mode is changed from the tuner mode to the tape mode by the mode select switch,
Or when the play key is operated in the tape mode, if it is in a half-packed state, after fully opening the operation panel,
Control is performed such that the pack is loaded and then the operation panel is opened to the memory angle position.

<Effects of the Invention> As described above, according to the present invention, the opening angle of the operation panel is stored, and when a predetermined signal is generated after the operation panel is fully opened or fully closed from the stored opening angle position, the operation panel is opened. Since it is configured to open to the opening angle position, the AC
When C-ON or when ejecting / inserting the recording medium, the operation panel can be automatically rotated to the open angle position that was previously set and is easy to see and has good operability. It is possible to improve operability.
