Abstract: A document managing method for a printing device is provided. The document managing method includes the following steps. Firstly, a printing mechanism prints a document with plural papers, and transfers the plural papers to a paper collection platform. Then, a management module manages the plural papers from two lateral sides of the plural papers. Then, a paper ejection module ejects a first portion of the plural papers at a first speed, and then ejects a second portion of the plural papers at a second speed. Consequently, the plural papers are exited from the paper collection platform. Then, the management module is separated from the two lateral sides of the plural papers, so that the plural papers fall down to a supporting tray. The first speed is faster than the second speed.

Abstract: A lens module and a manufacturing method of the lens module are provided. The manufacturing method includes the following steps. Firstly, a circuit substrate is provided. Then, an image sensor chip is placed on a top surface of the circuit substrate. Then, plural electrical connection paths are formed between the image sensor chip and the circuit substrate. Then, plural stacking spacer structures are formed on a top surface of the image sensor chip by a stacking process. Then, plural protective sidewalls are formed to cover the electrical connection paths. Then, a glass substrate is placed over the stacking spacer structures. Then, a lens holder structure is placed on a substrate top surface of the glass substrate directly. The glass substrate is supported by the stacking spacer structures. Consequently, the glass substrate can be maintained at the position over the image sensor chip.

Abstract: A backlight kit includes a base member, a covering member, a slim-type light guide element and an illumination module. The covering member is combined with the base member. The slim-type light guide element and the illumination module are arranged between the base member and the covering member. After the illumination module emits a light beam to the slim-type light guide element, the light beam is transferred through the slim-type light guide element. Consequently, a luminance gradient region is formed on the surface of the covering member.

Abstract: An image capturing device includes a casing, a camera assembly, an adjustment element, a first stopping structure and a second stopping structure. The camera assembly is disposed within the casing. A portion of the camera assembly is exposed outside the casing. The adjustment element is connected with the camera assembly, and rotatable relative to the casing. As the adjustment element is rotated, the camera assembly is correspondingly rotated. The adjustment element includes a contacting structure. The first stopping structure and the second stopping structure are arranged between the casing and the adjustment element and located at different positions. When the camera assembly is switched to a horizontal photographing mode, the contacting structure is positioned at the first stopping structure. When the camera assembly is switched to a vertical photographing mode, the contacting structure is positioned at the second stopping structure.

Abstract: A touchpad module includes a touch member, a base plate, a supporting element and a switch. The touch member includes a first touch region and a second touch region. The base plate is located under the touch member. The supporting element is arranged between the touch member and the base plate. The supporting element is aligned with the second touch region. The switch is arranged between the touch member and the base plate. The switch is aligned with the second touch region. When a pressing force is applied to the second touch region of the touch member, the pressing force is transmitted to the base plate through the supporting element. Consequently, the base plate is subjected to deformation. The switch is triggered in response to the deformation of the base plate.
