An improved mechanism for rotatable image taking device, the rotatable mirror set in front of a fixed image-taking device with angle of reflection controlling mechanism at the rear side of the mirror. The mechanism includes a fixed rod with universal joint at the center, a horizontal rotating rod with universal joint, and a vertical rotating rod with universal joint. There are also three universal joints situated at the center, upper or lower side, and left or right side of the back face of the mirror. The invention can reduce the total cost of the rotatable image-taking device and improve the speed of changing angles.

What is claimed is: 1. An improved mechanism for rotatable image-taking device, including: a rotatable mirror provided in front of a stationary image-taking device; and a reflective angle controlling mechanism provided to the rear of said mirror, wherein said mechanism comprises: a support rod erected at the bottom face of said reflective angle controlling mechanism, and a central universal joint provided to the top thereof, wherein said central universal joint is pivoted to the center of the rear of said mirror; a horizontal rotating device comprising: a first motor provided to the top thereof, a first rotating rod connected to a shaft of said first motor, a first universal joint rod with an end being pivotally connected to a side of said first rotating rod and another end being pivoted to the center of either a right side or left side of the rear of said mirror, a first detecting device provided to the bottom of said first rotating rod, wherein said first detecting device moves along with the rotation of said first rotating rod, so as to determine displacement along a horizontal-axis; a vertical rotating device comprising: a second motor provided to one end thereof, a second rotating rod connected to a shaft of said second motor, a second universal joint rod with an end being pivotally connected to a side of said second rotating rod and another end being pivoted to the center of either an upper side or lower side of the rear of said mirror, a second detecting device provided to the other end of said second rotating rod, wherein said second detecting device moves along with the rotation of said second rotating rod, so as to determine displacement along a vertical-axis; said mirror including: three universal joint supports, which are each provided to the center, either upper side or lower side, and either left side or right side of the rear of said mirror, for pivoting to the central, horizontal and vertical universal joints of said controlling mechanism. 2. The improved mechanism for the rotatable image-taking device of claim 1, wherein said detecting devices are either variable resistors, position encoders, or any angular sensing device. 3. The improved mechanism for the rotatable image-taking device of claim 1, wherein said mirror is one of a flat mirror, convex mirror, or concave mirror.
