Optical Drive Picker/Loader Mechanism

      This article describes an optical drive loader that has a
built-in gripper to pull a disk caddy into the loader.

As illustrated in Figs. 1 and 2, the preferred embodiment of this
invention comprises:
  o  A gripper 1 with fingers 2 which is attached to a driving block
3
      by a spring 4.  The gripper 1 and the driving block 3 are
guided
      in the X direction by slots 5 provided on a movable frame 6
which
      can be pivoted against the OO' axis of a stationary frame 7.  A
      motor 8 which is mounted on the movable frame 5 drives the
      driving block 3 along the X direction via a lead screw 9.  The
      spring 4 is pre-loaded with a force that is sufficient to pull
      the caddy 10 out of its storage slot without causing permanent
      damage to any component, the sensing means 11 detects a
premature
      separation between the driving block 3 and the gripper 1 to
alarm
      a potential jamming problem.  The movable frame is lifted
upward
      by the spring 22.
  o  A data reader 12 with a spindle motor 13 which is mounted to the
      stationary frame 7.
  o  A magnetic chuck 14 which is suspended to the stationary frame 6
      by a holder 15.

During operation, the caddy is moved in the Y direction so that its
ears 16 engage the fingers 2, the motor 8 pulls the driving block 3,
the gripper 1 and the caddy 10 along the (+X) direction...
