| 1. Contour reading device (1), in particular for eyeglass frame (10) rims, including a support (3, 4) for holding an article whose contour is to be read and a turntable (6) that is rotatable relative to the support (3, 4) about a rotation axis and carries a reading subassembly (15) that includes a feeler (8) mobile in a direction parallel to the rotation axis of the turntable (6) and in a plane transverse to the rotation axis of the turntable (6),
which reading device (1) is characterized in that the reading subassembly (15) further includes:
a rotation axis (A) referred to as the carrier axis transverse to the surface of the turntable (6),
a carrier arm (18) which is mounted at one end to turn about said carrier axis (A) and at the other end of which said feeler (8) is mounted, whereby the feeler (8) is mobile relative to the turntable (6) along a circular arc path centered on said carrier axis (A).
