Problems solved by technology

[0005] However, since the slider 14 can only move back and forth between the central position and the top position on the left or right side, it means that the tilt sensor 10 can only output three kinds of signals correspondingly, which is relatively limited in application.
For example, this kind of tilt sensor 10 can only make the display direction of the photo change back and forth between a preset position, a 90-degree left rotation, and a 90-degree right rotation, but it cannot dynamically follow the hand-held electronic device continuously. Changing the tilt angle, while continuously changing the display direction of the photo

Embodiment Construction

[0025] Below in conjunction with accompanying drawing, structural principle and working principle of the present invention are specifically described:

[0026] refer to figure 2 and image 3 , is a particle moving orientation sensor according to the first preferred embodiment of the present invention. The particle moving orientation sensor mainly includes a casing 20 , a circuit board 23 , two light emitting components 24 , two light detecting components 25 , and a plurality of particles 26 .

[0027] The housing 20 includes a first housing part 21 and a second housing part 22 . The first housing portion 21 cooperates with the second housing portion 22 to form a substantially circular accommodating space 210 . The accommodating space 210 has a first area 211 , a second area 212 , a third area 213 , and a fourth area 214 which are sequentially arranged in a ring and communicate with each other. The first area 211 , the second area 212 , the third area 213 , and the fourth ...

Abstract

The invention discloses a particle migration type aspect sensor comprising a shell, at least one lighting assembly, two light detection assemblies and a plurality of particles, wherein a containing space is formed in the shell and is provided with a first zone, a second zone, a third zone and a fourth zone which are arranged in a four-ring shape; a first opening and a second opening are formed on the shell, the first opening is communicated with the first zone, and the second opening is respectively communicated with the second zone and the fourth zone; the lighting assembly emits ray towards the containing space via the first opening; and the light detection assemblies detect the ray in the containing space via the second opening. The particles are arranged in the containing space, and the particles can partially block the lighting assembly or the light detection assemblies when the particle migration type aspect sensor inclines, thus the light detection assemblies can respectively detect the ray with specific intensity and output an electrical signal with specific intensity.

Description

technical field [0001] The invention relates to a sensor, in particular to a particle moving orientation sensor. Background technique [0002] With the popularization of handheld electronic devices such as digital cameras or mobile phones with camera functions, viewing photos on them has become normal. Therefore, a photo rotation function, which can automatically rotate the display direction of photos along with the rotation of the handheld electronic device, is gradually appearing on the handheld electronic device. [0003] refer to figure 1 , is a tilt sensor 10 disclosed in Taiwan Patent Application No. 95142815, which can be installed in the above-mentioned handheld electronic device to sense its rotation, and output a corresponding signal to change the display direction of the photo. As shown in the figure, the inclination sensor 10 includes a casing 11 defining a V-shaped groove 110, a light-emitting component 12 for emitting light into the V-shaped groove 110, and t...
