Claim 1
Independent Claim
189 words
A pivoting mirror device for an apparatus which scans information tracks on an information carrier with the aid of a radiation beam, which device comprises: a pivoting mirror (1) which is pivotable about at least one pivoting axis (5, 6) and which has a radiation-reflecting front (2) and, on the reverse side thereof, a back (3), and a mirror bearing arrangement (9) comprising: a rigid bearing support (10) having a first end (11) situated near the back (3) of the pivoting mirror and a second end (12) which is remote therefrom, and an elastic bearing (13) of a rubber-like material which is connected both to the back (3) of the pivoting mirror (1) and to the bearing support (10), which material surrounds the first end of the bearing support and a portion (14) of the bearing support near the first end, characterized in that said portion (14) of the bearing support (10) which is situated near the first end (11) has a cross-section which varies from a minimum transverse dimension at the first end (11) to a maximum transverse dimension at a location situated nearer the second end (15).

A pivoting mirror device for an apparatus which scans information tracks on an information carrier with the aid of a radiation beam, which device comprises: a pivoting mirror (1) which is pivotable about at least one pivoting axis (5, 6) and which has a radiation-reflecting front (2) and, on the reverse side thereof, a back (3), and a mirror bearing arrangement (9) comprising: a rigid bearing support (10) having a first end (11) situated near the back (3) of the pivoting mirror and a second end (12) which is remote therefrom, and an elastic bearing (13) of a rubber-like material which is connected both to the back (3) of the pivoting mirror (1) and to the bearing support (10), which material surrounds the first end of the bearing support and a portion (14) of the bearing support near the first end, characterized in that said portion (14) of the bearing support (10) which is situated near the first end (11) has a cross-section which varies from a minimum transverse dimension at the first end (11) to a maximum transverse dimension at a location situated nearer the second end (15).
Claim 3
Dependent Claim
57 words
A pivoting mirror device as claimed in claim 1, characterized in that the rubber-like material surrounds the bearing support (10) over the entire length of said portion (14) of varying cross-section, the bearing support also being surrounded by a layer of a rubber-like material at the said location (15) where the cross-section has the maximum transverse dimension.
Claim 4
Dependent Claim
36 words
A pivoting mirror device as claimed in claim 2, characterized in that for affixing the elastic material to the bearing support (10), the bearing support has a constricted portion (60) adjoining said portion of varying cross-section.
Claim 5
Dependent Claim
28 words
A pivoting mirror device as claimed in claims 1, 2, or 3, characterized in that said cross-section has the form of a longitudinal section of a truncated cone.
