Pickup device for otpical disk

An optical pickup device comprising:

• an objective lens driving means supporting an objective lens in a floating manner so that said objective lens faces a surface of an optical disk;
• and
• a body from which a light beam is projected towards the objective lens,
• said objective lens driving means comprising a actuator base and an objective lens holder supported in a floating manner with respect to said actuator base, said actuator base being provided with a first flat portion positioned in a vicinity of the optical disk surface, a second flat portion apart from the optical disk surface, and an oblique connecting portion connecting said first and second flat portions, said first flat portion is formed with a through hole through which the light beam passes and said second flat portion being formed with a magnetic circuit, said objective lens holder being composed of a thin thickness portion holding the objective lens and a portion, thicker than the thin portion, holding a drive coil applied with magnetic flux by the magnetic coil in which said objective lens holder is supported in a floating manner so that thin portion faces said first flat portion and said thicker portion faces said second flat portion, and
• said body being composed of a first supporting portion for supporting said first flat portion, a second supporting portion for supporting said second flat portion and an intermediate portion disposed below said through hole formed to the first flat portion, and means disposed to the intermediate portion of the body for reflecting the light beam from a light beam source towards the optical disk surface through the through hole and the objective lens.
