Microfiche camera

Claim 2

A microfilm camera comprising: a. a housing; b. a flat, horizontal, transparent document platen on a top wall of said housing on which a document to be microfilmed is positioned face-down; c. a light source located in said housing below said document platen; d. a film holder; e. an x-y slide system for moving said film holder in x and y directions, f. a lens mounted in a lens mount, said lens mount being positioned between said document platen and said film holder; g. said lens including a format mask, and including means for moving said lens temporarily toward said film holder and said format mask into contact with film held thereby during each exposure, and means for moving said lens away from said film holder and said format mask out of contact with film held thereby, immediately after each exposure; h. a shuttter adjacent said lens system; and i. an inner light-tight wall enclosing said film holder and including a flexible bellows having a film pack receiving aperture therein, said aperture including light-tight sealing means, whereby a film pack can be inserted partway through said bellows in light-tight relationship thereto.

Claim 3

The apparatus according to claim 1 including a second document platen adjacent a bottom wall of said housing adjacent which a document is placed face-up, and means for exposing film in said film holder to a document on either one of said platens.

Claim 4

means for energizing said shutter solenoid;

Claim 5

means for energizing said shutter solenoid;

Claim 6

The apparatus according to claim 2 wherein said exposing means includes a movable mirror positioned between said platens and having two different positions, one for reflecting light from each of said platens, and means for moving said mirror to each of said two different positions.

Claim 7

means for energizing said light source to illuminate a document on Said document platen;

Claim 8

means for energizing said light source to illuminate a document on Said document platen;

Claim 9

means for moving said format mask of said lens away from said film after the exposure is made; and

Claim 10

means for moving said format mask of said lens away from said film after the exposure is made; and

Claim 11

A microfilm camera comprising: a. a housing; b. a flat, horizontal, transparent document platen on a top wall of said housing on which a document to be copied is positioned face-down; c. a mirror located in said housing below said document platen; d. a light source located in said housing below said document platen; e. a film holder; f. an x-y slide system for moving said film holder in x and y directions; g. a lens and lens mount positioned between said mirror and said film holder, said lens including a format mask; h. a shutter, including a solenoid, positioned adjacent said lens for opening and closing a light path through said lens to said film holder; i. a film pack opening in said upper surface of said housing above said x-y slide system for inserting a film pack into and removing it from said film holder; j. an inner light-tight wall enclosing said film holder and including a flexible bellows having a film pack receiving aperture therein, said aperture including light-tight sealing means, whereby a film pack can be inserted partway through said bellows in light-tight relationship thereto; k. an operating system for operating said camera when a document-record button is pushed comprising: l. means for moving said lens and for moving said format mask of said lens into light-tight contact with film on said film holder;

Claim 12

A microfilm camera comprising: a. a housing; b. a flat, horizontal, transparent document platen on a top wall of said housing on which a document to be copied is positioned face-down; c. a mirror located in said housing below said document platen; d. a light source located in said housing below said document platen; e. a film holder; f. an x-y slide system for moving said film holder in x and y directions; g. a lens and lens mount positioned between said mirror and said film holder, said lens including a format mask; h. a shutter, including a solenoid, positioned adjacent said lens for opening and closing a light path through said lens to said film holder; i. a film pack opening in said upper surface of said housing above said x-y slide system for inserting a film pack into and removing it from said film holder; j. an inner light-tight wall enclosing said film holder and including a flexible bellows having a film pack receiving aperture therein, said aperture including light-tight sealing means, whereby a film pack can be inserted partway through said bellows in light-tight relationship thereto; k. an operating system for operating said camera when a document-record button is pushed comprising: l. means for moving said lens and for moving said format mask of said lens into light-tight contact with film on said film holder;

Claim 13

The apparatus according to claim 4 including a second document platen located adjacent a bottom wall of said housing below said mirror, and means for rotating said mirror about a horizontal axis to a second position for reflecting light from said second document platen toward said film holder.

Claim 14

means for moving said film holder a predetermined distance after said format mask has moved out of contact with said film in said film holder.

Claim 15

means for moving said film holder a predetermined distance after said format mask has moved out of contact with said film in said film holder.

Claim 16

The apparatus according to claim 4 wherein said means for moving said format mask of said lens into contact with film held in said film holder includes a cam follower connected to said lens, a cam located adjacent said cam follower for moving said lens toward and away from said film holder, a compression spring connected to said cam for holding said lens away from said film holder, and a solenoid connected to said cam for moving said lifting cam, when said solenoid is energized, to move said cam follower to cause said lens to move toward said film holder a sufficient distance such that said format mask will contact film held in said film holder.

Claim 17

The apparatus according to claim 4 wherein said shutter includes a rotary solenoid actuator and said shutter is adjacent that end of said lens mount facing said mirror.
