Abstract: A motion-detecting module includes a PCB, a light-emitting unit, and a light-sensing unit. The light-emitting unit is electrically disposed over the PCB. The light-sensing unit has a light-sensing die electrically disposed on the PCB and a package cover covered on the light-sensing die, and the package cover has a through hole corresponding to the light-sensing die and a transparent element disposed in the through hole. The present invention does not need extra package protection body of the prior art for protecting the light-sensing die during the transport of the light-sensing module. The present invention use original package cover to prevent the light-sensing die from being damaged by external force, and the original package cover shelters the light-sensing die from extra stray light.

Abstract: An improved packaging module of an optical sensor includes a circuit board and an optical sensor module. The optical sensor module comprises a linear optical sensor, and an illuminating unit respectively electronically connected with the circuit board, and a second protective body packaging the linear optical sensor and the illuminating unit. A first protective body covers the linear optical sensor and illuminating unit, the second protective body defines a first aperture corresponding to the linear optical sensor and a second aperture corresponding to the illuminating unit. A first light pipe set at the first aperture and a second light pipe set at the second aperture, the linear optical sensor, illuminating unit, first protective body and second protective body are combined integrally, which makes the packaging module process simple, adjustment of the optical sensor module's components achieved automatically, and the space of the optical sensor is reduced.

Abstract: A motion detecting device for sensing rotation and inclination variation information, includes a light-emitting unit, a sensor control unit, an image sensing unit, a rotation-sensing unit, an inclination-sensing unit, a data storing unit, and an operation unit. The image sensing unit is used to receive a light-reflecting signal. The rotation-sensing unit is used to sense a rotation variation signal of the motion detecting device. The inclination-sensing unit is used to sense an inclination variation signal of the motion detecting device. The operation unit is used to calculate a motion direction and a motion velocity of the motion detecting device relative to a motion surface according to the light-reflecting signal from the image-sensing unit, a rotation angle of the motion detecting device according to the rotation variation signal, and an inclination angle of the motion detecting device according to the inclination variation signal.

Abstract: An optical handwriting input device includes: a casing, a refill, a PCB, an image data communication module, and a motion detection module. The refill received in the casing has a pen nib, and the pen nib is selectably exposed from a bottom side of the casing or hidden inside the casing. The PCB is received in the casing and disposed beside one side of the pen refill. The image data communication module is received in the casing and electrically connected to the PCB. The motion detection module is received in the casing and electrically connected to the PCB. Hence, the present invention can detect the movement track of the optical handwriting input device by receiving a light-reflecting signal from a detection surface, and the movement track is identified and inputted to a digital electronic device to become handwriting displayed on a monitor of the digital electronic device.
