Title: Optical head
Inventor: OKUDA MICHITAKA
IPC: G11B7/135
Filed: 1989-02-27
Abstract: PURPOSE:To reduce the number of components of an optical head and to easily perform adjustment among the components by employing such constitution that a reflected laser beam from an information record is diffracted by using a hologram element, and it is detected by an optical detector. CONSTITUTION:A laser beam S wave emitted from a semiconductor laser 13 is totally reflected on a polarizing beam splitter 2, and advances in a direction of objective lens 5. The laser beam is converged on the lens 5, and information is recorded on an optical system information recording medium 3. Next, a laser beam P wave emitted from the semiconductor laser 13 full-transmits the beam splitter 2, and advances to a direction of lens 5. And the laser beam is converged on the lens 5, and the beam having the information of the medium 3 is reflected. The reflected light is transmitted to the hologram element 6 via the lens 5 and the splitter 2, etc. And part of the light is diffracted in a +1st-order direction at the element 6, and the information of the medium 3 is read out at the optical detector 7. By employing such constitution, it is possible to dispense with a specific part to separate the laser beam other than the element 6.

After that, the lowest container 23 is conveyed into a separating chamber 2 through a  convey-out port 1B by a push-out member 27. The other containers 23 are then sequentially conveyed into the chamber 2 in the same way. Only the separated lenses are housed in the containers  23, which are conveyed into a drying chamber 3 and stacked on a vertically movable rest 29. The  lenses are warmed and dried while moisture collection on the surface of the lenses is prevented by  no-moisture atmosphere gas vaporized by an evaporator in the drying chamber 3. The uppermost  container 23 is thereafter pushed out through a convey-out port 3B by a push-out member 36.  The other containers 23 are then sequentially conveyed out in the same way.
