Abstract: A keyboard device includes a membrane circuit board, a base plate, a key structure and a light-emitting element. The key structure includes a keycap, a connecting element and an elastic element. The connecting element is arranged between the base plate and the keycap. The elastic element is arranged between the keycap and the membrane circuit board. The light-emitting element is electrically connected with the membrane circuit board and located under the elastic element. After the light beams from the light-emitting element are projected upwardly and transmitted through the elastic element, the light beams are uniformly projected to the keycap. Consequently, the keycap has the uniform illuminous efficacy.

Abstract: A photo frame module includes a display device and a fixing structure. The display device includes plural sensing units. When a terminal device is fixed by the fixing structure, a screen of the terminal device is in parallel with the display device. After the terminal device is fixed, an original image shown on the screen of the terminal device is sensed by the plural sensing units, and a sensed image corresponding to the original image is shown on the display device.

Abstract: A luminous keyboard includes plural key structures, a switch circuit board, a supporting plate, a backlight module and plural ring-shaped structures. The switch circuit board is located under the keycaps of the key structures. The supporting plate is located under the switch circuit board and connected with the key structures. The backlight module is located under the supporting plate. The backlight module generates a light beam. The plural ring-shaped structure are disposed on the switch circuit board and arranged around the corresponding key structures. When the light beam is reflected by the key structures, the light beam is received by the plural ring-shaped structure. Due to the material properties of the ring-shaped structures, the periphery regions of the keycaps generate a uniform luminous effect.
