Description

[Detailed description of the invention] <Industrial application field> This invention relates to audio equipment.

<Prior art> In complex products such as audio equipment that can select multiple operating modes, it is common to have only one key dedicated to mode switching, and to operate the key to switch modes sequentially. Met.

The selected mode is displayed using pictograms or the like.

<Problems to be Solved by the Invention> However, with this selection and display method, it is difficult to distinguish the current mode due to similarities in pictographs, etc.

On the other hand, it has been difficult to provide a single mode switching key for each mode due to the reduction in panel area due to miniaturization of devices.

Means for Solving the Problems> The present invention has been made to solve the above problems, and includes a sound source switching means for selecting one of a plurality of sound sources and connecting it to an audio output means, and a sound source switching means for selecting one of a plurality of sound sources and connecting it to an audio output means. A plurality of operation means corresponding to each sound source provided for inputting a sound source selection signal to the means, and a predetermined operation means corresponding to the selected sound source upon detecting that the operation means corresponding to the selected sound source has been operated again. The present invention is characterized by comprising a function control means for operating the function.

<Operation> When the operating means is operated and a sound source selection signal is input, the sound source switching means switches the sound source to a predetermined sound source designated by the operation. Further, when the sound source selection signal corresponds to the sound source currently selected at the bottom, the function control means detects this and causes the sound source to perform a predetermined operation.

<Example> An embodiment of the present invention will be described based on the drawings.

Even in this tuner mode, the control device 1 constantly monitors whether or not the tuner mode key 21 is operated (step 63), and if it is operated, switches the reception band (step 64), and then steps again. Return to 63. If the tuner mode key 21 is not operated in step 63, other processing such as responding to the operation input of the function key 53 is performed (step 65).

On the other hand, if the tuner mode key 21 is not operated in step 61, it is then determined whether the CD mode key 22 is operated (step 66). If no operation has been performed, other processing is performed (step 67).
), the sound source is switched to the CD player 42 and set to CD mode (step 68). Even in this CD mode, the control device J constantly monitors whether or not the CI mode key 22 is operated (step 69).
If no operation is performed, another process is performed (step 7).
2). If the tuner mode key 21 has not been operated, a DISK selection operation is performed (step 70), and it is then checked whether the tuner mode key 21 has been operated (step 71). If the operation is being performed, the process returns to step 69 and returns to step 62 to enter the tuner mode again.7 Note that although only the tuner 41 and CD player 42 are shown in this flowchart, the tape player 40 is also shown.

Next, the operation will be explained.

FIG. 11 shows a flowchart of the operation of the control device 1' when switching sound sources and the display state of the mode display 3 at each step.

After the operation starts (step 80), in the tuner mode state (step 81), the display state of the mode display 3 is ``TAPE'', which is the corresponding sound source name, on the tape display section 30 and the CD display section 32, respectively, as shown in the figure. "CD" is displayed. However, the tuner display section 31 shows "BND" indicating a predetermined operation base, and if the tuner mode key 21' is operated in this state, the receiving band will be changed. In this state, the control device 3' constantly monitors the operation status of the CD mode key 22' (step 82).If the CD mode key 22' is not operated, the process proceeds to step 83. Other processing is performed, but if operated, the sound source will be switched to CD and the CD will be played.
mode (step 84). Also, at this time, the display on the mode display 3 is changed to "PI TUNE" indicating the sound source name for the tuner display section 31. On the other hand, the CD display section 32 indicates that the switching operation of Day-1 is being performed. DISK”
(Step 85). In this CD mode, the control device 1' monitors the operating state of the CD mode key 22' (step 86).
If 2' is operated, the disk is switched (
Step 87), return to step 86 again. Step 8
If the CD remote key 22' is not operated in step 88, then the operating state of the tape mode key 20' is checked (step 88). If the tape mode key 20' has not been operated, the process returns to step 86, but if it has been operated, the process proceeds to step 89, switches the sound source to the tape player 40, and enters the tape mode (step 89). That is, in the CD mode, the operation status of the tape mode key 20' and the CD mode key 22' is constantly monitored repeatedly, and this continues until the CD mode key 22' is operated.

After entering the tape mode in step 89, the controller 1' changes the display on the mode indicator 3. The display on the CD display section 32 is changed to #Cp#, and in this state
When the D mode key 22' is operated, it is indicated that the CD mode is to be entered. Also, the display on the tape display section 30 is changed to "TAPE" indicating the sound source name or "PROG" indicating the operation (step 90)a. Note that only the tape mode key 20' and CD mode key 22' are shown in the flowchart. Although not shown, a similar operation is performed for the tuner mode key 21'.

In the above embodiment, the mode key 2' corresponding to the selected sound source also functions as a function key, so the number of operation keys can be reduced and each key can be made larger, improving operability. Furthermore, in the second embodiment, the operation to be performed when the mode key 2' corresponding to the selected sound source is operated is displayed, so that the operability is further improved.

<Effects of the Invention> As explained above, the audio equipment of the present invention includes a sound source switching means that selects one of a plurality of sound sources and connects it to the audio output means, and a sound source selection signal is input to the sound source switching means. a plurality of operation means corresponding to each sound source provided for the purpose of the present invention; and a function control means for detecting that the operation means corresponding to the selected sound source is operated again and operating a predetermined function corresponding to the sound source. Since the operating means corresponding to the sound source also functions as a function selection means while a sound source is selected, it is possible to reduce the number of operating means and increase the size of the operating means and their accompanying display. Therefore, effects such as improved operability can be obtained.
