| 摘要 |
The present invention relates to a work-indicating unit of a magnetic control exercise apparatus. A plurality of circuit board sets are positioned around a flywheel. Each circuit board set has several sensing elements and light-emitting elements (e.g. monochromatic or polychrome LED). Each sensing element corresponds to a magnet set of the magnetic resistance elements in order to detect the resistance voltage value produced by the flywheel in unit time. The resistance voltage is used to actuate the light-emitting elements. Accordingly, the amount of exercise in unit time is displayed by the light-emitting elements, which are lit or not lit depending on the amount of resistance voltage.
