A key-duplicating machine

A key duplicating machine (1) comprising:

• a support structure (10),
• a front operational area (2) which is accessible by the operator and which is removably covered and separated, at least partially, from the external environment (3) by means of a covering and/or protection crankcase (4) which is movable with respect to said structure of support (10), in said front operational area (2) being housed at least one cutter (11), and/or another cutting element, and at least one terminal (12) for locking a key,
• a rear containment area (5) which is covered and separated from the external environment (3) by a casing (6) mechanically fixed to said support structure (10),
• a control and command unit (19) of the various components of said machine (1), comprising a mechanism (20) for moving said crankcase (4) for covering and/or protecting the front operational area (2), said crankcase (4) being configured to be mounted on a fixed structure (10, 7, 8, 6) of said duplicating machine (1) so as to be able to be moved with respect to said fixed structure (10, 7, 8, 6), said mechanism (20) comprising:
• at least one rotating body (25) which is operated in rotation by a motorization unit (30) and which is configured to come into contact and act directly on a portion (21) of said crankcase (4), or on an integral element to said portion (21), to thereby cause the movement of said crankcase (4) with respect to said fixed structure (10, 7, 8, 6),
• said motorization unit (30) and said at least one rotating body (25) are positioned within the overall dimensions of said crankcase (4) to be moved.
