US Patent:

48148326, Mar 21, 1989

Filed:

Jan 28, 1988

Appl. No.:

7/149647

Inventors:

Juergen Lein - West Henrietta NY
Michael Brookmire - Pittsford NY
Robert Powers - Rochester NY
Joel Hotelling - Naples NY

Assignee:

Itek Graphix Corp. - Waltham MA

International Classification:

G03B 2760

US Classification:

355 73

Abstract:

An automatic vacuum feed and hold down system is provided having a transport belt with vacuum grippers, a peripheral vacuum channel surrounding the platen, and a lead edge blow apparatus. In the preferred embodiment the transport belt consists of polyester fabric selectively coated with plastisol sealant to define a window area similarly shaped but smaller than the platen and suction grippers within the window area. In the preferred mode of operation a lifting apparatus raises the belt away from the exposed photosensitive sheet on the platen and the natural curl of the sheet, together with the lead edge blow, cause the sheet to release from the platen. The lifting apparatus then lowers the belt and suction is reapplied to the grippers, whereafter the belt and sheet are raised and advanced to deliver the exposed photosensitive sheet for processing.

Assignee:

Itek Corporation - Lexington MA

International Classification:

G03B 1750

US Classification:

354 84

Abstract:

The disclosure is directed to an extremely compact camera-processor which is configured to sharply reverse the direction of the exposed light sensitive sheet as it leaves the exposure plane. The light sensitive sheet is thereafter driven downwardly into a processor bath along with a relatively flimsy receptor sheet.

Appl. No.:

7/618717

Inventors:

Robert H. Powers - Honeoye Falls NY
Daniel H. Robbins - Rochester NY

Assignee:

A.B. Dick Company - Chicago IL

International Classification:

G03B 2770

US Classification:

355 66

Abstract:

A graphic camera/platemaker optical system is described having a copyboard for an original subject, a lens, an image plane and a mirror. The copyboard, lens and mirror are independently movable such that they may move in different directions in order to produce a variable scale image or reproduction of the original onto the image plane. The movable elements are positioned by separate stepping drives controlled by a common microprocessor.

Appl. No.:

5/675390

Inventors:

Robert H. Powers - Rochester NY

Assignee:

Itek Corporation - Lexington MA

International Classification:

G03B 1726

US Classification:

354275

Abstract:

A two-part replaceable cassette-like device is provided, having a disposable cassette portion and a light sealed buffer box, having a pair of drive rollers therein and which is detachably fastened to the disposable cassette, whereby the photosensitive material driven out of the cassette will be driven through the light sealed buffer box into a camera processor. Upon exhaustion of the photosensitive media within the cassette, the buffer box is removed from the cassette for reuse and the cassette is thrown away. A gear coupled to the buffer box roller material drive means is automatically rotated during insertion and withdrawal of the buffer box to and from the camera due to roller contact with a stationary drive gear positioned within such camera.

Inventors:

Robert H. Powers - Rochester NY

Assignee:

Itek Corporation - Lexington MA

International Classification:

G03B 1726

US Classification:

354277

Abstract:

A pivotable camera back is provided containing a film cartridge having a movable light sealing member for preventing light from entering the cartridge when the camera back housing is pivoted to an open position for access thereto, together with a sealing member actuation device for causing the light sealing member to open with respect to the cartridge feed orifice to permit photosensitive material to be fed to the imaging area upon the closing of the camera back housing.
