Abstract
The microfiche carrier slides laterally on front and rear ball bearings between the carrier and subcarrier. The front bearing permits vertical separation of the carrier from the subcarrier and the rear ball bearing then permits the race member carried by the carrier to be withdrawn from between the upper and lower sets of ball bearings. In use the carrier is latched to the subcarrier by a latch carried by the transparent index pressure plate. The subcarrier is mounted on the base by ball bearings. The base contains the electrical components and the light source and condenser lens. The base can be withdrawn from the housing as a unit with the carrier attached.
Claims9
A microfiche assembly comprising,
- a base provided with spaced parallel rails extending fore and aft on the base,
- a subcarrier slidably mounted on the rails,
- a fiche carrier,
- spaced parallel front and rear bearing means between the carrier and subcarrier enabling the carrier to move sideways relative to the subcarrier,
- means preventing vertical separation of said rear bearing means,
- said front bearing means allowing vertical separation,
- means for latching the carrier to the subcarrier by preventing vertical separation of the front bearing means to retain the front bearing means effective and prevent removal of the carrier from the subcarrier,
- said latching means being operable to release the carrier to permit vertical separation of the front bearing means,
- said rear bearing means permitting horizontal separation when the front of the carrier is raised.
