Abstract
Abstract Apparatus for printing an image upon a film negative in a camera is disclosed. The apparatus includes a series of tapes which carry figures to be recorded on the film by a portion of the light which enters the camera through the lens at the time a picture is taken and passes through the tapes to impinge upon the film. Either the tapes or the figures carried by the tapes can be transparent. The tapes are superimposed one upon the other in proximity to the film exposure area with spaces on the tapes to allow one or more figures carried by each of the tapes to be recorded simultaneously on the film.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
272 words
In a camera having an interior picture-taking area defined by a lens at the forward portion and a film negative located at the rear portion for exposure by light entering through the lens when a picture is taken, the combination comprising: a. a plurality of figure-bearing endless tapes movably secured to the camera on two sets of rotatable disks, the disks in each set being concentrically mounted on the exterior of the camera, one set of the disks being mounted on the base of the camera on each side of the picture-taking area with each tape being mounted on a separate disk in each set of disks, each of the tapes having the property that one or the other of the tape or the figures thereon is transparent while the other is opaque to the passage of light, and each tape having a portion thereof located in proximity to the film negative in a super-imposed condition with respect to the other tapes so that a portion of the light passing through the lens on its way to the film negative when a picture is taken will be intercepted by an opaque portion of each of the tapes, the figures on each tape having a spaced relationship with respect to each other with the spacing being of a size such that one or more figures on each of the tapes can be projected simultaneously onto the film negative by the light which enters the camera through the lens, and b. means for individually adjusting the tapes in order to position the desired figures appearing on the tapes in proximity to the film negative.

Dependent Claim

Claim 3
Dependent Claim
38 words
The apparatus of claim 1 wherein the tapes are twisted in a 1/2 twist with respect to their longitudinal axes on either side of the area in which the tapes are superimposed in proximity to the film negative.
Claim 4
Dependent Claim
72 words
The apparatus of claiM 1 wherein each tape is wound around a pair of guides between each set of concentric disks and the picture-taking area, one of the guides in each pair of guides being located on the exterior of the camera and the other guide in each pair of guides being located on the interior of the camera, both guides in each pair being mounted on the base of the camera.
Claim 5
Dependent Claim
56 words
The apparatus of claim 3 wherein the means for individually adjusting the tapes includes a series of levers attached to one of the sets of concentric disks, a separate lever being provided for each disk in the set and each lever being in engagement with its respective disk by means of a ratchet and pawl combination.
Claim 6
Dependent Claim
28 words
The apparatus of claim 4 further including means connected to each lever to bias the respective tape in the direction in which the tape is to be advanced.
Claim 7
Dependent Claim
32 words
The apparatus of claim 4 further including indicating means to provide an indication to the camera operator of the figures on each tape which are indexed for projection onto the film negative.
Claim 8
Dependent Claim
63 words
The apparatus of claim 6 wherein the indicating means includes a second set of figures on each tape, said second set of figures being correlated with the figures to be projected upon the film negative so that when a figure in the second set of figures is visible to the camera operator, a corresponding figure is indexed for projection upon the film negative.
Claim 9
Dependent Claim
72 words
The apparatus of claim 6 wherein the indicating means includes a second set of figures on the outer surface of one of the sets of concentric disks, said second set of figures being correlated with the figures to be projected upon the film negative so that when a figure in the second set of figures is visible to the camera operator, a corresponding figure is indexed for projection upon the film negative.
