Since there is no member surrounding the LED, there is also a disadvantage that the LED light cannot be efficiently emitted to the LED display unit.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and can easily assemble and disassemble the LED bracket, and irradiate the LED display unit without attenuating the light of the LED. It is an object of the present invention to provide an LED bracket fixing structure of an electronic device that can be operated.

[0009]

In order to achieve the above object, an LED bracket fixing structure for an electronic device according to the present invention has a light-transmitting LED display portion exposed on the surface of the electronic device and a flange around the LED display portion. LED bracket, L
A case having a hole for inserting an ED bracket,
It is characterized by being sandwiched and fixed between a D-bracket and a substrate on which an LED for irradiating light is mounted.

Further, the LED bracket in the LED bracket fixing structure of the electronic apparatus according to the present invention is characterized in that it has a reflector for reflecting the light of the LED to the LED display unit.

According to the LED bracket fixing structure for an electronic device of the present invention, the flange of the LED bracket can be pressed and fixed between the case and the substrate.
The bracket can be easily assembled and disassembled, and since the reflector is provided around the LED, the light of the LED can be efficiently emitted to the LED display unit.
