Abstract
Tuning apparatus including a scale provided with indicia corresponding to different broadcast frequencies to which the tuning apparatus is tunable and a pointer movable across the scale to indicate the particular broadcast frequency to which the tuning apparatus is tuned. The pointer is 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 apparatus is tunable. A key removably mounted on the guide shaft is bi-directionally driven therealong by the movable support, the key being selectively operative to engage a desired one of the markers to move the engaged marker along the guide rail as the support is moved, whereby the marker is set to a desired position by reason of its engagement with the key.
