Abstract
Abstract Recording apparatus which reproduces enlarged copies of microfilm and/or document material by controlling the position of a reader screen and a lens-positioning assembly in relation to a copier platen. The lens-positioning assembly includes a fixed frame and a movable frame supported from the fixed frame for swinging a lens member toward and away from the focal plane of the apparatus. Control apparatus including sensing devices are used to position the lens member into and out of the focal plane according to whether the recording apparatus is used in the microfilm or document copying mode of operation.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
189 words
In an automatic electrostatic recording machine in which a recording member is continuously moved past a plurality of processing stations to produce copies of input information, an improvement enabling reproduction of enlarged copies of microfilm or original size copies of document information positioned on a platen comprising, reader means for projecting and reading microfilm and adapted for movement relative to a platen of a recording machine, shaft means operatively associated with said reader means for moving said reader means from a first position in which copies of microfilm are reproduced to a second position in which copies of document information placed on said platen are reproduced a lens-positioning assembly for positioning a lens member in the focal plane of said recording machine operatively associated with said shaft means, said lens-positioning assembly comprising a fixed frame and a movable frame pivotally supported from said fixed frame for swinging movement toward and away from said focal plane, and control means operatively associated with said shaft means for enabling said lens member to be positioned in said focal plane depending on whether said reader means is in said first or second positions.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
102 words
Apparatus according to claim 1 wherein said control means comprises a wheel member carried on said shaft means, a key member operatively associated with said lens-positioning assembly arranged to be received in a recess formed in said wheel member, means for biasing said key member into engagement with said wheel member, a sensing arm adapted for pivotal movement and having a sensing member connected thereto, and a control member arranged in the path of said sensing member to cause said sensing arm to pivot thereby causing said key member to disengage from said wheel member against the action of said spring means.
Claim 4
Dependent Claim
13 words
Apparatus according to claim 1 wherein said lens-positioning assembly comprises a parallelogram linkage.
Claim 5
Dependent Claim
26 words
Apparatus according to claim 1 wherein said shaft means includes a locking element operatively connected thereto for obtaining registration of said reader means with said platen.
