Abstract:
A pen holder for holding thereon a pen for drawing a visible line on a board while a sensor generates a signal corresponding to a position of the pen holder on the board, comprising,an emitter for emitting at least one of light beam and supersonic waves to be received by the sensor so that the signal is determined from the received at least one of light beam and supersonic waves; a holder body including an opening which is arranged at a longitudinal end of the pen holder in such a manner that a front portion of the pen including an end at which end the visible line is drawn on the board projects from the opening out of the pen holder, and through which a part of the pen other than the front portion of the pen is mountable from an outside of the pen holder onto the pen holder so that the pen is held on the pen holder; and a locking member for holding the part of the pen stationarily thereon, the locking member being movable on the holder body between first and second positions, the at least one of the light beam and the supersonic waves is permitted to be emitted by the emitter when the locking member is positioned at the first position, and the at least one of the light beam and the supersonic waves is prevented from being emitted by the emitter when the locking member is positioned at the second position.
