Lift-up Mechanism of the Front Bases
For the lift-up mechanism of the front bases, rotary levers are used to allow the extensions to be easily folded and
unfolded.
When the extensions are folded, they are invisible from the front without detracting from the esthetic design of the front
bases. When the body is lifted up with the extensions, the shapes of the front bases and extensions match in the form of
an arc with a look of a unified and beautiful appearance.

The lift-up mechanism is designed so that the bottom surface of the front base is aligned with the bottom surface of the
extension when it is unfolded, to allow the body to receive its weight at almost a right angle to the direction of gravity.
Consequently, the front base can support the heavy weight of the TS-890S with sufficient allowance and without adding
stress to the rotary arm.
