Abstract

A leaf thickness sensing device (1) having mounting apparatus (9, 10) for flexibly mounting the device adjacent a leaf whose thickness is to be sensed, a leaf support element (4) coupled to the mounting apparatus, a displaceable leaf abutting (6) juxtaposed with respect to and biased towards the leaf support element so as to be in firm, non-destructive abutting contact with a leaf to be releasably retained on the leaf support element; a displacement transducer element (11) responsibly coupled to the leaf abutting element and serving to generate a signal corresponding to displacement of the second element relative to the first element.
