The color of one of them.

The movable member 51 of the present embodiment has a connecting body 511 disposed around the light-emitting element 31 and rotatably disposed on the housing 1 and an operating portion 512 exposing the housing 1. Specifically, the connecting body 511 is a hollow circle. a cylindrical surrounding wall, the connecting body 511 is rotatably disposed in the housing 1, so that the moving direction 500 is the circumferential direction of the connecting body 511, and the connecting body 511 is provided with a plurality of windows 513 along the circumferential direction thereof. The color patches 52 are disposed on the connection body 511 and respectively correspond to the windows 513. The movable member 51 of the present embodiment further includes two side portions 514 and a shaft 515, each side portion 514 is formed with a side hole 516, and the side portion 514 may specifically be, for example, for example, in the housing 1 . In the form of a plate, the side hole 516 may specifically be a hole defined by a tubular structure extending from the side portion 514 or directly penetrating the side portion 516. The connection body 511 is coupled between the two side portions 514, and the specific aspect may be The one side portion 514 is integrally connected to the connecting body 511, and the other side portion 514 is detachably connected to the connecting body 511 (for example, through a screw lock, a snapping, etc.), and the two ends of the shaft 515 are respectively protruded and protruded from the two sides. The side hole 516 of the portion 514 is fixed in the housing 1 (for example, locked to the bottom cover 12), and the light-emitting module 3 is fixed to the shaft 515 and located between the side portions 514 and surrounded by the connecting body 511.

When the movable member 51 is fixed to the casing 1, the movable member 51 is at a position with respect to the opening 111, and the connecting body 511 must be kept in a state in which the upper half is protruded by the opening 111 of the top cover 11 to protrude the casing 1, The operation portion 512 for turning the finger is formed. When the connecting body 511 is rotationally displaced relative to the housing 1 and the shaft 515 in the movable direction 500, the different color patches 52 can be faced to the light exiting side 311 of the light emitting element 31, so that the light of the light emitting element 31 can pass through the color patch. 52 generates light of a corresponding color and enters the light guide plate 4 to project toward the keycap 21. Therefore, when the user needs to change the illumination color, the touched movable member 51 is connected to the exposed portion of the body 511 to change the color of the illumination light. Effect.

In order to enable the movable member 51 to be adjusted more accurately and conveniently, the single color patch 52 completely corresponds to the light exiting side 311 of the light emitting element 31 without generating light of the light emitting element 31 while generating mixed light through the two color patches 52. The color, the movable member 51 and the casing 1 may also be provided with a matching interference structure (such as a ratchet structure or a structure in which the bumps are matched with the equally spaced grooves) in the movable direction 500 of the movable member 51. The movable member 51 can be rotated by a fixed angle and a fixed distance. In addition, an light-emitting window 122 can be formed between the light-emitting side 311 of the housing 1 corresponding to the light-emitting element 31 and the light guide plate 4. The light passing through the other color patches 52 is blocked by the structure of the light-emitting element 31 passing through the other color patches 52 by the structure inside the light-emitting window 122, and only the light passing through the color-color sheet 52 corresponding to the light-emitting side 311 is projected onto the light guide plate 4.

The color plates 62 are respectively disposed in the windows 613. The specific structure of the operating portion 612 is a tab protruding from the top edge of the connecting body 611. And in the second embodiment, the opening 111' of the top cover 11 is an elongated strip extending in a lateral direction. When the movable member 61 is disposed in the housing 1, the connecting body 611 is located between the top cover 11 and the bottom cover 12 and The direction of the connecting body 611 is parallel to the extending direction of the opening 111 ′, and the operating portion 612 is exposed from the opening 111 ′ to the top cover 11 to be slidable in the direction of the opening 111 ′, thereby driving the connecting body 611 along The longitudinal direction 600 is displaced such that any one of the color patches 62 corresponds to the light exiting side 311 of the light emitting element 31. Therefore, in the second preferred embodiment, the movable direction of the movable member 61 is the longitudinal direction 600 of the connecting body 611. When the illumination color needs to be switched, the toggle operation portion 612 is displaced along the direction of the opening 111 ′ to drive the connection body 611 to slide along the longitudinal direction 600 thereof, so that the color patches 62 of different colors on the connection body 611 can be corresponding. The purpose of changing the illumination color is to reach the light-emitting element 31.

Similarly, in the second preferred embodiment, the housing 1 may be formed with a light-emitting window 122 ′ for blocking the light of the light-emitting element 31 passing through the color-changing plate 311 of the light-emitting side 311. In the second preferred embodiment, the movable member 61 is formed with a bump 610, and the housing 1 is further formed with a plurality of grooves 112 parallel to the longitudinal direction 600 and communicating with the opening 111'. The bump 610 and the groove 112 are formed. The interference structure for limiting the displacement amount of the movable member 61 is provided. When the movable member 61 is moved by a fixed distance, the bump 610 is caught in the groove 112 corresponding to the position, and the movable member 61 is provided for the fixed distance adjustment, and is avoided. The movable member 61 is freely movable.

In addition, in the second preferred embodiment, the bottom cover 12 of the casing 1 is further formed with a long groove-shaped guide groove 120 having a direction parallel to the longitudinal direction 600, and the guide groove 120 can be embedded in the connecting body 611 of the movable member 61. Thereby, the effect of guiding the displacement of the movable member 61 in the moving direction 600 is produced.

It should be noted that, in the position of the movable member 61 in the second preferred embodiment, the direction in which the movable member is operable is not limited to the translation. For example, the connecting body 611 may also be disposed in a disk shape and partially. The top cover 11 of the housing 1 is exposed, and the color piece 62 is disposed around the connecting body 611, and the effect of the toggle rotation to make the different color patches 62 correspond to the light-emitting elements 31 is also achieved.

In summary, the present invention can provide the effect of manually changing the color of the keyboard illumination light by the structure of the color switching mechanism 5, 6 regardless of whether the rotation activity mode or the translation activity mode can be achieved. The object of the invention.

In addition, the present invention allows the user to adjust the illumination color of the keyboard as needed according to the conventional method of setting the cold light panel. For the wired keyboard, with the independent driving backlight design, the user can manually change the illumination light. Color, no need to use software or circuit control means; for wireless keyboard devices, you can also use the main body to configure the power supply, change the color of the keyboard by yourself, without having to boot and start the operating system.

The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the simple equivalent transformation and modification according to the scope of the invention and the description of the invention, All remain within the scope of the invention patent.
