<p> Also, LEDs (lighting) are often used to display the status of electronic devices. For example, the first light is emitted when the power is on, the second light is emitted when the hard disk is accessed, and the third light is emitted when wireless communication is performed to drive an optical disk drive or the like. For example, the fourth light is emitted when the light is turned on. In this way, it is convenient for the user to display the state of the electronic device by lighting or the like, but on the other hand, if too many lights are arranged, it goes against the demand for miniaturization of the electronic device and space saving inside the case. And that salt plum has become a difficult problem.</p><p> An object of the present invention is to provide a television device and an electronic device having improved state discrimination.</p>

<p> The television apparatus of the embodiment includes a printed wiring board provided with a notch, and a plurality of first light emitting diodes provided on the printed wiring board and capable of irradiating light in a direction parallel to the printed wiring board. It has a plurality of light receiving units fitted inside the notch so as to correspond to the plurality of first light emitting diodes, and one display unit on which the light entering from the plurality of light receiving units is displayed.

For example, as schematically shown in FIG. 6, when the first light emitting diode 25 is arranged at a position far from the housing 12, a distance is secured between the first light emitting diode 25 and the housing 12. Therefore, the light from the two first light emitting diodes 25 is emitted to the outside of the housing 12 through the opening 14 as shown by the alternate long and short dash line. However, as shown in FIG. 7, when the housing 12 is made more compact and the distance between the housing 12 and the first light emitting diode 25 cannot be sufficiently secured, the first light emitting diode 25 is used. Light is blocked by the housing 12 without passing through the opening 14, as indicated by the alternate long and short dash line. According to the above configuration, for example, even when the state as shown in FIG. 8 is obtained and the distance between the housing 12 and the first light emitting diode 25 cannot be sufficiently secured, the light emitting diode 25 is directed toward the display unit 15C. It can irradiate sufficient light. As a result, it is possible to improve the visibility of light in the display unit 15C and to reduce the size of the housing 12 of the television device 11.

Further, the lens 15 has a substantially symmetrical shape with respect to the central axis 33 of the main body 15A. According to this configuration, since the light receiving unit 15B is arranged at the same distance and the same angle with respect to the display unit 15C, the light from any of the first light emitting diodes 25 has the same appearance in the display unit 15C. Can be done.

Further, the television device 11 is provided on the printed wiring board 22 and has a shade 26 that surrounds a portion separated from the lens 15 around each first light emitting diode 25. According to this configuration, the light from the first light emitting diode 25 is not diffused to the surroundings, and the efficiency of illumination can be improved.

Further, the television device 11 is provided on the printed wiring board 22 at a position separated from the edge portion 32, and includes a second light emitting diode 27 capable of irradiating light in a direction intersecting the printed wiring board 22.
