The action of said apparatus then, is described.
Fig. 6 is the block diagram of action of the audio devices 1 of the explanation signal source selection device that is built-in with embodiment 1.Fig. 7 A, 7B be in the expression embodiment 1 by MPU 62 control LED ri, LEDgi (i=1 ..., 5) the figure of control model.Fig. 7 A represents the control model under the holding state, and Fig. 7 B represents the control model of power connection state.
At first, when the such power supply of audio devices 1 and for example Vehicular accumulator cell was electrically connected, MPU 62 started and begins to carry out preset program, and the operating state that makes audio devices 1 is holding state (step S1).
Then, MPU 62 reads the signal source kind of information that is stored in the state storage unit 63, the signal source kind that this signal source kind of information is represented is presented at signal source and selects on the UI unit 11 (step S2) as the signal source kind of selecting automatically when the power connection state exchange.At this moment, shown in Fig. 7 A, MPU 62 lights the LED gi corresponding to the green of this signal source kind, extinguishes LED gk corresponding to the green of other signal source kind (k ≠ j) and all red LED r1～LEDr5.
In state storage unit 63, do not have under the situation of storage signal source category information, MPU62 can select prearranged signal source category (for example " AM "), as the signal source kind of selecting automatically when the power connection state exchange, this signal source kind of information stored into state storage unit 63 and be presented at signal source select on the UI unit 11.
Then, under holding state, MPU 62 monitors whether detected power connection operation (step S3), and for just selecting the signal source kind of demonstration on the UI unit 11 whether the ejection (step S4) of recording medium has taken place in signal source.
MPU 62, and the voltage according to the output line of the pushbutton switch SW that selects UI unit 11 from signal source judges whether to have taken place the power connection operation.In addition, MPU 62, according to 61 detected by the signal source control module, from the control signal of CD reproduction units 51 or MD reproduction units 52, judge the ejection whether recording medium has taken place for the signal source kind that is showing.
Then, MPU 62, at the At time of eject that recording medium has taken place for the signal source kind that is showing, switch the demonstration (step S5) of the signal source kind of selecting automatically when the power connection state exchange.At this moment, MPU 62, read the next signal source category information in the state storage unit 63, that switch the signal source kind of information of the signal source kind before showing that is stored in, the signal source kind after this signal source kind is shown as switching.In addition, MPU 62, the signal source kind of information of the signal source kind before deletion switch to show from state storage unit 63, and be initial (step S6) with the signal source kind of information of switching the signal source kind after showing.
For example, in state storage unit 63, new sequences with " CD ", " FM1 " stores 2 signal source kind of information, under the situation that in step S2, has shown signal source kind " CD ", during from CD reproduction units 51 ejection CD, MPU 62 extinguishes the LED g1 of signal source kind " CD ", and the LED g3 of signal source kind " FM1 " is lighted.Subsequently, continue LED g3 is lighted.
In addition, for example the new sequences with " CD ", " MD ", " FM1 " stores 3 signal source kind of information in state storage unit 63, under the situation that in step S2, has shown signal source kind " CD ", during from CD reproduction units 51 ejection CD, MPU 62 extinguishes the LED g1 of signal source kind " CD ", and the LED g2 of signal source kind " MD " is lighted.Subsequently, from MD reproduction units 52 ejection MD the time, MPU 62 extinguishes the LED g2 of signal source kind " MD ", and the LED g3 of signal source kind " FM1 " is lighted.But, under holding state, new sequences with " CD ", " MD ", " FM1 " in state storage unit 63 stores 3 signal source kind of information, in step S2, shown under the situation of signal source kind " CD ", when the recording medium (MD) of the signal source kind " MD " that does not show by At time of eject, MPU 62 will be stored in the signal source kind of information deletion of " MD " in the state storage unit 63.At this moment, MPU 62 continues to make the LED g1 of signal source kind " CD " to light.
Shown in Fig. 7 A figure, when detecting the ejection operation of recording medium, MPU 62 make corresponding to the LED gi of the signal source kind of this recording medium (i=1 ..., 5) extinguish, till pop-up action finishes.
Like this, under holding state,, show the signal source kind of when the power connection state exchange, selecting automatically according to the signal source kind of information that is stored in the state storage unit 63.
Under holding state, MPU 62, voltage when the output line of the pushbutton switch 11f that selects UI unit 11 according to signal source, judge and taken place to the push of the rotating operation unit 11f of signal source selection UI unit 11, when being the power connection operation, the operating state that makes audio devices 1 is to power connection state exchange (step S7).Thus, to all composed component supply capabilities of audio reproduction unit 32.
In addition, to the power connection state exchange time, MPU 62 makes display mode that signal source selects UI unit 11 begin to change from the display mode of holding state.Under the power connection state, the signal source kind during MPU 62 selects with the demonstration of the 1st form shows selectable signal source kind with the 2nd form.In this embodiment 1, shown in Fig. 7 B, under the power connection state, MPU 62 makes the LED rj (j=1 of the redness of the signal source kind in the selection, ..., 5) light, (k ≠ j) light makes other LED rp (p ≠ j), LEDgq (q ≠ k) extinguish to make the LED gk of the green of selectable signal source kind.At this moment, MPU 62 is via signal source control module 61, determine in CD reproduction units 51, whether to have inserted CD and reproduction, and in MD reproduction units 52, whether inserted MD and reproduction, to judge whether signal source kind " CD ", " MD " are selectable signal source kind.That is,, just can select, can not select otherwise be judged as signal source kind " CD " because of exportable sound signal is judged as signal source kind " CD " as long as in CD reproduction units 51, inserted CD.
Then, MPU 62 reads the initial signal source kind of information that is stored in the state storage unit 63, and by signal source selector switch 54 select corresponding to the represented signal source kind of this signal source kind of information, from the input (step S8) of audio signal output device.This moment, selected signal source kind was identical with signal source kind shown in step S2.
In addition, MPU 62, with the information providing of the kind (and signal source kind as required) of this audio signal output device to signal source control module 61, signal source control module 61, supply with control signal to this audio signal output device, and export the sound signal (step S9) of this signal source kind.
Thus, the sound signal that will be exported by audio signal output device (any one in CD reproduction units 51, MD reproduction units 52 and the radio broadcasting receiving element 53) arbitrarily supplies to electronic volume 55 from signal source selector switch 54.Electronic volume 55 is according to the amplitude of regulating this sound signal from the control signal of MPU 62.MPU 62, will supply to electronic volume 55 corresponding to the control signal of being adjusted operating unit 18 detected operational tons by sound.Then, the sound signal of exporting from electronic volume 55 is exaggerated device 56 amplifications, and the sound signal after the amplification is exported to loudspeaker etc.By not shown wave filter and the actuator (effector) that is arranged on amplifier 56 primes, realize corresponding to the operation of acoustic characteristic being set button 20 and balanced device button 21, based on reverberation time characteristic and frequency characteristic from the control signal of MPU 62.
Like this, when detecting power connection when operation, MPU 62, begin under audio reproduction unit 32 output holding states to be selected by signal source the sound signal of the shown signal source kind in UI unit 11 automatically.
Under the power connection state, MPU 62 monitors whether signal source kind blocked operation (step S10) has taken place, whether the ejection (step S11) of recording medium has taken place and whether power supply opening operation (being used for the operation to the holding state conversion) (step S12) has taken place.
MPU 62 judges whether to have taken place signal source kind blocked operation according to the signal of selecting the rotary encoder ENC of UI unit 11 from signal source.MPU 62 is according to this signal, determine signal source is selected the direction of operating and the operational ton of rotary manipulation of the rotating operation unit 11f of UI unit 11, and, be judged as the operation of the diverse signal source kind of signal source in having taken place to select and select now according to this direction of operating and operational ton.MPU 62 is according to the direction of operating of signal source kind blocked operation and the diverse signal source kind of signal source in the definite and present selection of operational ton.At this moment, MPU 62 is only from determining other signal source kind the selectable signal source kind of this time point.
When signal source kind blocked operation took place, the signal source kind of information of the signal source kind after MPU 62 at first will switch stored (step S13) in the state storage unit 63 into.At this moment, this signal source kind of information is inserted into the starting point storage in state storage unit 63.That is, other existing signal source kind of information in the state storage unit 63, neither not deleted by overwrite yet.
Then, MPU 62, with the signal source kind of selecting after switching, select on the UI unit 11 to be presented at signal source with the diverse form of other selectable signal source, and, by the input (step S14) of signal source selector switch 54 selections corresponding to the audio signal output device of this signal source kind.In this embodiment 1, the demonstration of the signal source kind of selecting after the switching becomes redness from green, and the demonstration of the signal source kind of selecting before the switching becomes green from redness.
Then, MPU 62 will be corresponding to the information providing of the audio signal output device (and signal source kind as required) of the signal source kind after switching to signal source control module 61.Signal source control module 61 stops the output of the sound signal of the signal source kind before switching according to this information, and makes the output of the sound signal of the signal source kind after the switching begin (step S15).
Then, MPU 62 gets back to the monitored state of step S10～S12.
On the other hand, MPU 62, according to 61 detected by the signal source control module, from the control signal of CD reproduction units 51 or MD reproduction units 52, judged whether to take place the ejection (step S11) of recording medium.
Then, at the At time of eject that recording medium has taken place, MPU 62 deletes the signal source kind of information (step S16) of the signal source kind that ejection has taken place from state storage unit 63.In addition, MPU 62 judges whether the signal source kind that has taken place to eject reproduces (step S17).When At time of eject has taken place, the demonstration of this signal source kind changes to green flicker during finishing up to ejection.
When the signal source kind that has taken place to eject was being reproduced, MPU 62 read initial signal source kind of information (step S18) from state storage unit 63.Owing in step S16, deleted the signal source kind of information that the signal source kind that ejects has taken place, therefore, the signal source kind of information of in step S18, reading, the signal source kind of the previous selected mistake of the signal source kind that ejects has taken place in expression.
Then, MPU 62 makes signal source select UI unit 11 to show the represented signal source kind of this signal source kind of information, simultaneously, and the input (step S14) that signal source selector switch 54 is selected corresponding to the audio signal output device of this signal source kind.In this embodiment 1, the demonstration of the new signal source kind of selecting is varied to redness from green, for the signal source kind that ejects has taken place, is varied to not have from the demonstration of redness and shows (extinguishing).
Then, MPU 62 will be corresponding to the information providing of the audio signal output device (and signal source kind as required) of this signal source kind to signal source control module 61.Signal source control module 61 stops the output of the sound signal of the signal source kind that ejection has taken place according to this information, and makes the output of the sound signal of the signal source kind of newly selecting begin (step S15).
Then, MPU 62 gets back to the monitored state of step S10～S12.
In addition, when the At time of eject that recording medium has taken place, the signal source kind that has taken place to eject is not under the situation about reproducing, MPU 62, because selectable this signal source kind becomes and can not select before ejection, therefore, make about the signal source of this signal source kind and select the demonstration of UI unit 11 to stop (step S19).In this embodiment 1, when for At time of eject not having taken place, be varied to not have from the demonstration of green for this signal source kind and show (extinguishing) for the signal source kind reproduced.
Then, MPU 62 gets back to the monitored state of step S10～S12.
On the other hand, MPU 62 judges whether to have taken place power connection operation (step S12) according to the voltage of the output line of the pushbutton switch SW that selects UI unit 11 from signal source.That is, under the power connection state, when selecting the rotating operation unit 11f of UI unit 11 that push has taken place, be judged as the power connection operation for signal source.
Under the power connection state, voltage when the output line of the pushbutton switch 11f that selects UI unit 11 according to signal source, be judged as and taken place to the push of the rotating operation unit 11f of signal source selection UI unit 11, when being the power connection operation, MPU 62 makes the operating state of audio devices 1 to holding state conversion (step S1).Thus, by the control of MPU 62, stop the output of sound signal, signal source is selected the demonstration of the signal source kind of UI unit 11, also changes to the display mode of above-mentioned holding state.
In addition, when power supply disconnects (when the power connection state exchange becomes holding state), in state storage unit 63, because initial signal source kind of information becomes the selected signal source kind that goes out before disconnecting to power supply, therefore, under holding state, only this signal source kind is presented at signal source and selects on the UI unit 11, when to the power connection state exchange of next time, select this signal source kind in principle automatically.But, the selected signal source kind that goes out is the signal source kind of medium reproducing apparatus before disconnecting to power supply, when under holding state, extracting under the situation of recording medium, select the signal source kind of the previous selected mistake of this signal source kind from this medium reproducing apparatus.And then the signal source kind of previous selected mistake is based on medium reproducing apparatus, and, when having extracted from this medium reproducing apparatus under the situation of recording medium, select the signal source kind of previous selected mistake again.
Like this, because the signal source kind of medium reproducing apparatus might become under holding state and can not select, therefore, preferably in state storage unit 63, store the signal source kind of information of the signal source kind signal source kind in addition of 1 medium reproducing apparatus at least.
As described above, audio devices 1 is in any one operating state in holding state and the power connection state, make signal source select the display mode of the signal source kind of UI unit 11 to change according to operating state, and, signal source kind according to medium reproducing apparatus could be selected, and the demonstration of signal source kind is changed.
At this, example ejection, that signal source selects the demonstration of the signal source kind of UI unit 11 to change corresponding to signal source kind blocked operation and recording medium is described.Fig. 8 be in the explanation embodiment 1 corresponding to the ejection of signal source kind blocked operation and recording medium, signal source selects the figure of the example that the demonstration of the signal source kind of UI unit 11 changes.
State 1 among Fig. 8 is the power connection state, is the state that detects the power connection operation and selected signal source kind before.In state 1, owing to selected signal source kind " FM1 ", therefore, shows signal source category " FM1 ", LEDr3 azarin colored lights.In addition, in state 1, owing to be in the state that has inserted CD, therefore, be judged as signal source kind " CD ", " FM2 ", " AM " and can select and show LEDg1,4,5 bright green lamps.At this moment, owing to be in the state that does not insert MD, therefore, signal source kind " MD " is extinguished.
In the accompanying drawings, for convenience of explanation, represent with boldface letter during the azarin colored lights, during the bright green lamp with the black surround font representation, during light-off with black frame of broken lines font representation.Accompanying drawing beyond Fig. 8 also is identical manifestation mode.
In state 1, when rotating operation unit 11f is detected the operational ton of the predetermined anglec of rotation in the counterclockwise direction, select the selectable signal source kind " CD " of adjacency in the counterclockwise direction from " FM1 ".At this moment, even owing to detect to anticlockwise rotary manipulation, therefore the signal source kind " MD " in extinguishing can't be selected also for selecting.
Under these circumstances, when detecting the operational ton of the predetermined anglec of rotation along clockwise direction, select signal source kind " FM2 ", and then, when continuing when same direction detects the operational ton of the predetermined anglec of rotation, remove the selection of " FM2 " and select signal source kind " AM ".
Like this, MPU 62, according to by the detected rotary manipulation of rotary encoder ENC, select to select in the shown signal source kind in UI unit 11 1 by signal source.At this moment, when by the detected rotary manipulation amount of rotary encoder ENC, when having surpassed the rotary manipulation amount of preceding or the most last signal source kind of the arrangement that is used to select to be positioned at the signal source kind, MPU 62 is according to the rotary manipulation direction, and selection is positioned at the preceding or the most last signal source kind of the arrangement of signal source kind.In this embodiment 1,,, always select to be positioned at the signal source kind " CD " of the end that the demonstration of signal source kind arranges when rotating operation unit 11f is rotated to an angle when above in the counterclockwise direction the state of Fig. 81 time.In addition, when making rotating operation unit 11f be rotated in a clockwise direction certain angle when above, always select to be positioned at the signal source kind " AM " of another end.Do not shown that when having for 1 time at state to show " CD " " FM1 ", " FM2 " reach under the situation of " AM ", because current " FM1 " that is selecting becomes the end, therefore, rotating operation unit 11f is rotated several times in the counterclockwise direction, " FM1 " all can continue selected.
Then, when above-mentioned CD selection operation took place for 1 time at state, signal source selected UI unit 11 and state storage unit 63 to be transformed into state 2.
In state 2, the initial signal source kind of information of state storage unit 63 is " CD ", and next signal source category information is at selected " FM1 " that goes out of state 1 time.In addition, state 2 times, owing to selected signal source kind " CD ", and therefore, shows signal source category " CD ", LEDr1 azarin colored lights.In addition, state 2 times, be judged as and select signal source kind " FM1 ", " FM2 ", " AM ", LEDg3,4,5 bright green lamps.At this moment, owing to be in the state that does not insert MD, therefore, signal source kind " MD " is turned off the light.
When at 2 times CD of state by At time of eject, signal source selects UI unit 11 and state storage unit 63 to state 3 conversions.
In state 3, become and can not select because CD ejects signal source kind " CD ", the signal source kind of information of deletion " CD " from state storage unit 63, the initial signal source kind of information of state storage unit 63 becomes " FM1 ".Then, select this signal source kind " FM1 ".Therefore, in state 3, owing to selected signal source kind " FM1 ", and therefore, shows signal source category " FM1 ", LEDr3 azarin colored lights.In addition, state 3 times, be judged as signal source kind " FM2 ", " AM " can select, LEDg4,5 bright green lamps, at this moment, owing to be in the state that MD and CD all are not inserted into, therefore, signal source kind " CD ", " MD " turn off the light.
On the other hand, when when the power connection operation takes place for 2 times state, signal source selects UI unit 11 and state storage unit 63 to state 4 conversions.Because state 4 is holding state, therefore, be shown as green corresponding to the signal source kind " CD " of the initial signal source kind of information of state storage unit 63, other signal source kind does not then show.
Then, when detecting the power connection operation for 4 times at state, signal source selects UI unit 11 and state storage unit 63 to state 5 conversions.State 5 is the power connection state, automatically selects corresponding to " CD " of the initial signal source kind of information of state storage unit 63, promptly to be shown as under holding state green " CD ".State 5 times, this signal source kind " CD " is shown as redness, and selectable " FM1 ", " FM2 " reach " AM " and be shown as green.At this moment, because MD does not insert, therefore " MD " do not show.
On the other hand, when the At time of eject that detects CD at state for 4 times, signal source selects UI unit 11 and state storage unit 63 to state 6 conversions.Because CD is ejected, thereby the signal source kind of information of " CD " in the deletion state storage unit 63, the signal source kind of information of " FM1 " becomes initial.Because state 6 is holding state, therefore, be shown as green corresponding to the signal source kind " FM1 " of the initial signal source kind of information of state storage unit 63, other signal source kind does not then show.
As mentioned above,, select UI unit 11, show a plurality of signal source kinds of one or more signal source devices respectively as the signal source of display device according to above-mentioned embodiment 1.In addition, as the MPU 62 of state converter, the operating state of audio devices 1 is changed between holding state and power connection state.In addition, as the state storage unit 63 of memory storage, the signal source kind of information of the selected signal source kind that goes out under the storage representation power connection state.And as the MPU 62 of signal source kind selecting arrangement, under holding state, UI unit 11 is selected in the control signal source, makes it to show in a plurality of signal source kinds, is stored in the represented signal source kind of signal source kind of information in the state storage unit 63.In addition, MPU 62 as signal source kind selecting arrangement, select 1 signal source kind in a plurality of signal source kinds, when operating state during to the power connection state exchange, selects to be stored in the represented signal source kind of signal source kind of information in the state storage unit 63 from holding state.Particularly, MPU 62 under holding state, with the signal source kind of remaining audio signal output device mutually distinctively, show in a plurality of signal source kinds, be stored in the represented signal source kind of signal source kind of information in the state storage unit 63.
Thus, can under holding state, confirm the signal source kind that when being transformed into the power connection state, begins to select most simply.
In addition, according to above-mentioned embodiment 1, state storage unit 63, the signal source kind of information of the signal source kind of storage representation medium reproducing apparatus and represent the signal source kind of information of signal source kind of the previous selected mistake of this signal source kind.In addition, under holding state, under the situation that the signal source kind of medium reproducing apparatus has been shown, detect the At time of eject of recording medium, MPU 62 is with reference to the signal source kind of information in the state storage unit 63, UI unit 11 is selected in the control signal source, stop the demonstration of the signal source kind of this medium reproducing apparatus, make it to show the signal source kind of previous selected mistake of the signal source kind of this medium reproducing apparatus.
Thus, even because recording medium can't be chosen in the signal source kind time-like that begins to select most when converting the power connection state to by ejection, also can under holding state, confirm the signal source kind that substitutes simply.
In addition, according to above-mentioned embodiment 1, the signal source kind of information of medium reproducing apparatus that detects the ejection of recording medium under holding state is stored under the situation of state storage unit 63, from holding state when the power connection state exchange, MPU 62 is according to the signal source kind of information that is stored in the state storage unit 63, selects the signal source kind of previous selected mistake of the signal source kind of this medium reproducing apparatus.
Thus, even because the ejection of recording medium and can't be chosen in the signal source kind time-like that begins to select most when converting the power connection state to, also can automatically select the signal source kind that substitutes, under holding state, confirm the signal source kind that this substitutes simply.
In addition, according to above-mentioned embodiment 1, MPU 62 determines whether for the signal source kind of a plurality of audio signal output devices under the power connection state can output audio signal, UI unit 11 is selected in the control signal source, the signal source kind of show in the signal source kind of exportable sound signal with the 1st form (is the azarin colored lights at this), selecting, show remaining signal source kind with the 2nd form different (is the bright green lamp at this) with above-mentioned the 1st form, in addition, signal source kind that can not output audio signal does not then show.
Thus, the signal source kind time-like beyond the signal source kind that will select now selecting as the user can be confirmed this options simply.
