ABSTRACT:
An indication element driving device is incorporated within a tuning apparatus. The driving device comprises a casing of a substantially cylindrical shape with both end faces covered, a driving shaft is rotatably supported passing through the covered end faces of the casing and is adapted to be selectively shifted in its axial direction to a first and second position, and briefly rotated upon a tuning operation. A flywheel disposed coaxially with the driving shaft inside the casing and supported rotatably with respect to said driving shaft. A pulley disposed coaxially with driving shaft at an extended part thereof extending and projecting outside the casing has fine cord wound therearound. A first clutch is operable when the driving shaft is set to the first position, a second clutch is operable when the driving shaft is set to the second position. A rotation transmission is adapted, when the first clutch is operating, to speed up the rotation of the driving shaft and to transmit the rotation thus speeded up to the flywheel, and after rotating manipulation to the driving shaft is released, to transmit the high-speed inertial rotation of the flywheel to the pulley. When the second clutch is in its operating state, rotation of the driving shaft causes speed reduction and transmission of rotation to the pulley.
