  • Patent number: 6110425
    Abstract: A blood smear slide outloader including a platen for transferring a succession of slides from a dryer to a slide storage basket. The slides are sequentially discharged from one end of the dryer onto a platen and held firmly in place by a gripper. A single stepper motor then rotates the platen to a vertical position as it lowers both into alignment above a slot in the storage basket. A linear actuator causes the gripper to release the slide and deposit it into the slot. The platen then returns to the discharge end of the dryer to receive the next slide.
