Abstract
Apparatus which finds particular application in a tuning device of the type which is tunable to different broadcast frequencies and which includes a scale provided with indicia corresponding to such broadcast frequencies and a pointer movable across the scale to indicate the particular broadcast frequency to which the tuning apparatus is tuned, the pointer being supported by a movable support which is guided by a guide shaft. A plurality of markers are slidably guided along at least one guide rail and are individually settable to desired locations adjacent the scale, thereby representing particular broadcast frequencies to which the tuning device is tunable. A key also is slidable along the guide shaft with the movable support, the key being selectively operative to engage a desired one of the markers to move the engaged marker therewith as the support is moved, whereby the marker is set to a desired position by reason of its engagement with the key. The apparatus includes a rotatable support for receiving and supporting the guide shaft, which shaft has a longitudinal groove therein for receiving a nub provided on the rotatable support. The rotatable support is, in turn, rotated in…
