When the photodiode D2 senses the optical signal of the indicator lamp 62 transmitted from the corresponding first light guiding column 210, the resistance of the photodiode D2 is small, so that the base of the transistor Q is extremely high. At this time, the transistor Q is turned on, and the corresponding light-emitting diode D1 is turned on. The light emitted by the LEDs D1 is transmitted to the outside of the panel 300 through the second light guide bar 230, so that the signal of the indicator light 62 is transmitted to the outside of the fixing device 50 for the user to observe.

When the electronic device 60 is not operating, the indicator light 62 is turned off. The photodiode D2 does not sense the optical signal of the indicator lamp 62. At this time, the resistance of the photodiode D2 becomes large, that is, a near-off state, which causes the base of the transistor Q to be extremely low. The transistor Q is turned off, so that the corresponding light-emitting diode D1 does not emit light.

The light guiding device 200 and the fixing device 50 transmit the signal of the indicator light 62 at one end of the electronic device 60 to the other end of the electronic device 60 through the first light guiding column 210, and the photosensitive diode D2 on the circuit board 220 senses the first The optical signal of the indicator light 62 transmitted from the light guide column 210 controls the transistor Q to be turned on or off, thereby controlling the light emitting diodes D1 to be turned on or off, and the plurality of second light guiding columns 230 are used to illuminate the light emitting diodes. The light emitted by D1 is transmitted to the outside of the panel 300, so that the signal of the indicator lamp 62 is transmitted to the outside of the fixing device 50 for the user to observe.
