The apparatus includes devices for emitting a plurality of spaced light beams projected in directions to be intersected by the swing plane of a bat and a corresponding plurality of light receiving elements arranged to receive light beams reflected from the bat. Signals received by the light receiving elements are collected and supplied to a processing apparatus and the results of this processing are displayed on a display unit which provides indication of angle, speed, level, etc. of the swing. The information may also be provided to a printer. The apparatus indicates whether the swing is performed normally and if it deviates from normal indicates the error involved.
