In the figure, DPL indicates a display unit, CTR indicates various operation keys, LSR indicates an infrared light emitting element for the left seat, R
R is an infrared light receiving element, and RSR is an infrared light emitting element for the right seat. When each operator, for example, the operator in the left seat approaches his / her hand to operate the car audio device, the infrared light from the infrared light emitting element LSR that constantly emits infrared light is reflected by the operator's hand, and the reflected infrared light Is the infrared receiver RR
Is received at. Next, it is determined from the code included in the received infrared light that it is infrared light for the left seat, and the operation mode is changed to the operation mode for the left seat. Next, the operator operates the operation key unit CTR.
Switch the source with the source switch key, or adjust the volume with the volume. As a result, the switching key for each seat can be omitted, and the operator can operate without being aware of his / her own seat position. In the above description, the operation panel unit for the rear seat is used. However, the operation panel unit for the front seat does not include the left seat infrared light emitting element LSR, the infrared light receiving element RR, and the right seat infrared light emitting element RSR. No identification is performed.

(FIG. 2) issues an instruction to emit infrared rays to the infrared emission / reception control unit 11a through the bus 24, and the control unit 11a
Represents infrared light including a code indicating the left seat from the infrared light emitting element for left seat 11b, and infrared light emitting element for right seat 11c.
Then, an infrared ray including a code indicating the right seat is emitted (step 101). Next, the control unit 11a determines whether or not the infrared light emitted from the infrared light emitting elements 11b and 11c is received by the infrared light receiving unit 11d (step 10).
2) If no light is received, the process from step 101 is repeated. On the other hand, if the infrared light reflected on the operator's hand is received, the control unit 11a identifies the operator of the left or right seat based on the code included in the infrared light, and inputs the data for each operator seat to the system controller 14 ( Step 103). Next, the system controller 14 determines whether or not the operation has started within a predetermined time (step 104). If the operation does not start, the system controller 14 clears the operator seat identification data. Thereafter, the processing of step 101 and thereafter is repeated. On the other hand, if the operation starts within a certain time, the system controller 14 determines whether the operation is a source selection (step 105). If the operator's operation is not a source selection but another operation, for example, a volume up operation, the volume of the source that the operator is listening to is increased, and the process is terminated (step 110). On the other hand, if the operation of the operator is the source selection, the system controller 1
4 identifies the selected source, for example, the CD 16, and stores the correspondence between the operator's seat and the source in the built-in memory 14a (step 106). Thereafter, if the operator's seat is on the left (step 107), the selector 19 is controlled to output sound from the selected source (CD) to the left-seat headphones 22 (step 108). On the other hand, if the operator's seat is on the right (step 107), the selector 20 is controlled to output the sound from the selected source (CD) to the right-seat headphones 23 (step 10).
9). Thereafter, the process returns to the beginning, and repeats the subsequent processing after waiting for the next operation. If the operation is an operation other than the source selection (for example, a volume operation), in step 110,
From the correspondence table stored in the memory 14a, the source listening to the operator is identified, and the volume of the source is controlled. As described above, the description of the rear seat is made. In the front seat, the operation is performed using the front seat operation unit 12, the source selected by the operator of the front seat is controlled by the selector 18, and the sound is output from the speaker 21. Output.
