Abstract
Abstract A photographic device for aligning, spacing and printing a series of symbols upon a photosensitive member. The symbols are arranged on a grid-type transparency frame which is mounted on a rectangular coordinate system of sliding guides so that any one of a large number of symbols can be selected and moved to a printing position. An optical system focuses the light from the symbol onto a photosensitive member and the member is then developed and fixed to produce the desired indicia.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
187 words
A photographic composing device for projecting the image of indicia upon a photosensitive member comprising: a. An indicia bearing transparency, b. A carriage to support the transparency, said carriage comprising spaced pairs of rods normally disposed with respect to each other, bearing members slidably received upon the rods and a rigid transparency support member carried upon the bearing members c. Means including a first electric motor coupled to the transparency support for moving the transparency along one path of rectangular coordinates, a second electric motor coupled to the transparency to move it along the other path of rectangular coordinates, a plurality of limit stops to stop the transparency support at a desired location. d. An optical projection system, including a light source directed through a selected portion of the transparency and a lens system to focus the light coming through the transparency upon the photosensitive member, and e. Keyboard means connected to the said motors and limit stops to bring a selected portion of the transparency into register with the optical axis of the projection system to direct an image of the indicia upon the photosensitive member.

Claim 3
Dependent Claim
28 words
A device according to claim 1 in which the limit stops are operated by electrical solenoids each of said solenoids being responsive to a key on the keyboard.
Claim 4
Dependent Claim
109 words
A device according to claim 1 in which the carriage transport includes a first voltage divider, a movable contact secured to the transparency support, movable therewith and connected to at least one motor, a second voltage divider having a plurality of conductors connected thereto in spaced array, and the keyboard comprises a plurality of manually operable keys for each of the items of indicia on the transparency, each of said keys adapted to close a normally open pair of contacts connected in series between one of the conductors connected to the second voltage divider and said motor and a source of direct current power connected across both voltage dividers.
Claim 5
Dependent Claim
21 words
A device according to claim 3 in which a direct current amplifier is coupled to the input terminals of the motor.
