ABSTRACT:
An MPU sends pieces of information supplied by the input signals from a hand switch to a semiconductor memory device and the memory device stores these pieces of information. These pieces of information are: input points of an operation start signal and an operation end signal to a bottom drive unit; input points of a drive start signal of each bottom and a drive end signal of each bottom or a bottom drive time, information on lift-up or lift-down of each bottom; input points of a drive start signal and a drive end signal to a frame drive unit, information on lift-up or lift-down of a frame; and the type of an operated button of a hand switch. The data about bottoms is stored for both the back bottom and knee bottom.
