Patent ID: 7748585

Claim:
An automatic sensing and outputting device for an object, the device mainly comprising: a housing having a surface on which a fixing rod to be surrounded by the object is disposed, wherein a driving mechanism for generating power through a power supply is disposed in the housing; a control portion disposed at a predetermined position in the housing, wherein a control circuit board is disposed in the control portion, and the control circuit board comprises an operator sensor for sensing an operator and a zeroing sensor for sensing an output of the object; an output unit comprising a reel and a pressing plate, wherein the reel is disposed on the surface of the housing and engages with the driving mechanism so as to be rotated by the driving mechanism, and the pressing plate normally and slightly presses against the reel using an elastic member; wherein the control portion comprises a frame and a frame cover both accommodating the control circuit board, an actuating lever guiding hole is formed in the frame to accommodate an actuating lever attached to the pressing plate, a sensing area is formed on a top end surface of the frame near the operator sensor, the frame cover is longitudinally formed with an accommodating hole for accommodating the pressing plate, and one side of the accommodating hole is formed with two through holes through which the zeroing sensor passes.
