Can be made. More specifically, as shown in FIG. 7, “YES” and “NO” for selecting whether to light or not are displayed as menu items on the display section 2A of the LCD panel 2 (S1, S2), and in S2. If “NO” is selected, the LED is not lit but remains off (S4). On the other hand, if “YES” is selected, the external input to be removed is selected. The LED of the output terminal can be turned on from the unlit state (S3). Therefore, the user or the like can remove the external device using the lit LED corresponding to the external device to be removed as a mark, and can remove the desired external device without making a mistake.

  As described above, according to the television receiver 1, the first to sixth LEDs 21 to 21 serving as the light emitting means are respectively connected to the first to sixth external input / output terminals 11 to 16 which are a plurality of external input / output terminals. 26 is associated with each other, and among these external input / output terminals, the operation of the remote control transmitter 32 or the operation button 35 is performed on the screen of the display unit 2A of the LCD panel 2 configured in the television receiver 1. Since the LED lighting control unit 31 serving as a lighting switching unit that turns on the first LED 21 corresponding to the first external input / output terminal 11 selected by the above is provided, the user selects the first LED 21 that has been lit. As a mark, an external device such as a predetermined recording / reproducing device 4 can be connected to the corresponding first external input / output terminal 11 via the connection cable 5 without making a mistake. Therefore, it is possible to prevent an external device from being erroneously connected and to easily perform the connection work.

  Further, as shown in FIG. 3, a plurality of external input / output terminals (first to sixth external input / output terminals 11 to 16) are horizontally disposed in the horizontal direction of the television receiver 1, and these are disposed. The first to sixth LEDs 21 to 26 which are light emitting means are provided in the vicinity of the first to sixth external input / output terminals 11 to 16 and on the upper part thereof, and these first to sixth LEDs 21 to 26 are provided. Are arranged in the same direction as the lateral direction. As a result, when one of the external input / output terminals (for example, the first external input / output terminal 11) is selected and operated, the first LED 21 above the first external input / output terminal 11 is controlled to turn on the LED. By being lit by the unit 31, the user can use the lit first LED 21 as a mark, and the corresponding external input / output terminal, that is, the first external input / output terminal 11 without making a mistake, Since a device can be connected, the television receiver 1 excellent in connection workability can be obtained. Even if the first to sixth LEDs 21 to 26 are provided in the lower portion instead of the upper portions of the first to sixth external input / output terminals 11 to 16, the same operations and effects as when provided in the upper portion are provided. Needless to say.

  Further, as a modification, the first to sixth external input / output terminals 11 to 16 are arranged perpendicular to the longitudinal direction of the television receiver 1 and each of the arranged external input / output terminals 11 to 16 is provided. The first to sixth LEDs 21 to 26 are provided in correspondence with each of the left and right side portions so that these LEDs (first to sixth LEDs 21 to 26) are arranged in the vertical direction. Even when arranged in the same direction, when any one of the plurality of external input / output terminals is selected and operated, the LED corresponding to the selected external input / output terminal is turned on, Since the user can connect a predetermined external device without making a mistake to the corresponding external input / output terminal using the lit LED as a mark, connection workability with the external device can be improved. it can.

  Moreover, a plurality of external input / output terminals (first to sixth external input / output terminals 11 to 16) and the light emitting means (first to sixth LEDs 21 to 26) corresponding to these terminals are all televisions. It is provided on the back surface of the receiver 1. Therefore, the user can visually recognize a plurality of external input / output terminals and the corresponding LEDs simultaneously by viewing only the rear side of the television receiver 1. Therefore, while confirming the lit LED, the corresponding external input / output terminal can be simultaneously seen, so that the external device is not mistaken for the predetermined external input / output terminal corresponding to the lit LED. It becomes possible to connect securely.

  Further, since the LED as the light emitting means is blinked by the CPU 30 as the control means when the external input / output terminal is selected, the visibility is improved, and the user can select the external input / output terminal corresponding to the blinking LED. It becomes possible to grasp whether there is any more reliably and easily without misunderstanding.

  Furthermore, it has a timer 46 for measuring the time for which the LED is turned on, and after the predetermined time measured by the timer 46, the LED that is turned on is, for example, one minute later by the LED lighting controller 31. Since it is automatically turned off in a short time, power consumption can be reduced.

  In addition, the distance between each external input / output terminal and each LED corresponding thereto is 30 mm or less, that is, each of the LEDs corresponding to each external input / output terminal is in the vicinity (30 mm or less). ). Therefore, even if there are a plurality of external input / output terminals such as at least 3 sets or 6 sets or more as in the present embodiment, which LED corresponds to each of the plurality of external input / output terminals. It can be recognized at a glance whether or not it is.
