Abstract: A releasing method of an image capturing module of an electronic device, including an electronic device, wherein the electronic device includes a first machine body and an image capturing module pivotally connected to the first machine body, and the image capturing module is restrained by the first machine body to approach to the first machine body. Performing a posture estimation procedure includes, sensing a first included angle between the first machine body and a gravity direction for determining whether the electronic device is in a tent position. When the electronic device is determined to be in the tent position, determine whether a release instruction is received, so as to decide whether to perform a release procedure, wherein when the release procedure is performed, the first machine body releases the image capturing module, so that the image capturing module is turned up relative to the first machine body.

Abstract: A brush DC motor with reduction mechanism includes: a brush DC motor including a motor case, a stator section and a rotor section having a substantially cylindrical core, the stator section and the rotor section being received in the motor case; and a first reducing section drivable by the motor. The first reducing section includes a first sun gear, an external ring gear positioned around the sun gear and several planetary gears held between the external ring gear and the sun gear and engaged with the sun gear and the external ring gear. The first reducing section further includes a planetary carrier for locating the planetary gears in their true positions. Multiple parallel linear splines are formed on a circumference of the core at intervals. One end of the core with the splines formed on the circumference of the end serves as the sun gear of the first reducing section.
