Abstract
Abstract In a device that photographs a television screen a plurality of lenses are adjacently arranged on exchangeable lens supports. In order to achieve a higher image frequency and in order to avoid operating errors during the positioning of the lenses, the disclosure provides that the lens supports carrying the lenses are positioned in the image recording apparatus in a waiting position, and are selectively shifted by means of individual drives into the active position; a television monitor is moved into the correct distance relative to the selected lens support via an additional positioning drive.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
297 words
Image recording apparatus comprising a housing, a lens assembly in said housing comprising a plurality of lenses arranged adjacently and a separate shutter for each of said lenses, a photographic exposure position, a television monitor having a fluorescent screen for emitting light rays along an optical path of rays, film supply and collector magazine means, a transport device for the conveyance of individual film sheets from said magazine means into said photographic exposure position, and from the photographic exposure position into the magazine means, characterized in said lens assembly having respective shiftable lens supports (51, 52, 53) supporting respective sets of said lenses (79 through 87), said lens supports (51, 52, 53) each having an inactive position in which the associated set of lenses is offset from said optical path of rays and having an active position in which the associated set of lenses is operatively interposed in said optical path of rays, lens positioning drives (54, 55, 56) each connected with one of said lens supports (51, 52, 53) for selectively shifting each of said lens supports from the inactive position to said active position, a selector mechanism (98, 99, 100) for selecting a desired film subdivision and coupled with the lens positioning drives (54, 55, 56) for controlling the selective actuation of said positioning drives to effect positioning of the set of lenses corresponding to the selected film subdivision in said active position, and an additional positioning drive (9 through 16) operative for adjusting the distance of the television monitor (7) relative to the photographic exposure position (25), and responsive to actuation of said selector mechanism (98, 99, 100) for adjusting the distance between said television monitor (7) and the photographic exposure position (25) in accordance with the film subdivision selected by said selector mechanism.
Claim 2
Dependent Claim
297 words
Image recording apparatus comprising a housing, a lens assembly in said housing comprising a plurality of lenses arranged adjacently and a separate shutter for each of said lenses, a photographic exposure position, a television monitor having a fluorescent screen for emitting light rays along an optical path of rays, film supply and collector magazine means, a transport device for the conveyance of individual film sheets from said magazine means into said photographic exposure position, and from the photographic exposure position into the magazine means, characterized in said lens assembly having respective shiftable lens supports (51, 52, 53) supporting respective sets of said lenses (79 through 87), said lens supports (51, 52, 53) each having an inactive position in which the associated set of lenses is offset from said optical path of rays and having an active position in which the associated set of lenses is operatively interposed in said optical path of rays, lens positioning drives (54, 55, 56) each connected with one of said lens supports (51, 52, 53) for selectively shifting each of said lens supports from the inactive position to said active position, a selector mechanism (98, 99, 100) for selecting a desired film subdivision and coupled with the lens positioning drives (54, 55, 56) for controlling the selective actuation of said positioning drives to effect positioning of the set of lenses corresponding to the selected film subdivision in said active position, and an additional positioning drive (9 through 16) operative for adjusting the distance of the television monitor (7) relative to the photographic exposure position (25), and responsive to actuation of said selector mechanism (98, 99, 100) for adjusting the distance between said television monitor (7) and the photographic exposure position (25) in accordance with the film subdivision selected by said selector mechanism.
Claim 3
Dependent Claim
35 words
Image recording apparatus according to claim 1, characterized in that the sets of lenses carried by the respective lens supports (51, 52, 53) are arranged for insertion at different locations along the path of rays.
Claim 4
Dependent Claim
108 words
Image recording apparatus according to claim 1, with said transport device being of configuration to position a film sheet at the photographic exposure position so as to occupy a film sheet total area at said exposure position which has a longitudinally disposed margin area at one side of the path of the film sheets and a remaining major film sheet recording area, the lens assembly defining photographic fields which can be altogether light-projected exclusively onto said major film sheet recording area, while leaving unexposed the longitudinally disposed margin area, thereby to provide for a non-exposable binding margin along the length of an edge of each film sheet (23).
Claim 5
Dependent Claim
38 words
Image recording apparatus according to claim 1, characterized in mirror means (18) disposed in the optical path of rays (63) for deflecting the light rays emitted from the television monitor by approximately 90° toward the photographic exposure position.
Claim 6
Dependent Claim
70 words
Image recording apparatus according to claim 4, characterized in that the mirror means (18) is mounted for selective pivotal movement from its operative position to a position out of the optical path of rays (63) and that a camera (17) is mounted on the housing (1) and is centered relative to the non-deflected optical path of rays extending from the fluorescent screen toward the operative position of the mirror means.
Claim 7
Dependent Claim
32 words
Image recording apparatus according to claim 4, characterized in that the mirror means (18) is arranged between the television monitor (7) and a first lens plane (57, 58) of the lens assembly.
Claim 8
Dependent Claim
70 words
Image recording apparatus according to claim 1, characterized in that the shutters (88 through 96) of the individual lenses (79 through 87), arranged on the lens supports (51, 52, 53) are capable of being triggered successively in a predetermined order, and a program control comprising a trigger button (120) for actuation to initiate a complete sequential operation of the shutters of a selected set of lenses in said predetermined order.
Claim 9
Dependent Claim
63 words
Image recording apparatus according to claim 1, characterized in that a control console (97) for the purpose of individual selection of the photographic exposure field to be exposed on the film sheet (23) comprises a bank of keys (101) arranged in an array corresponding to a set of lenses of said lens assembly providing a maximally subdivided exposure field at said exposure position.
Claim 10
Dependent Claim
80 words
Image recording apparatus according to claim 8, characterized in said bank of keys (101) including respective keys (102 to 110), each key having a signalling lamp (111 through 119) associated therewith, only those signalling lamps being switched on which correspond to the film subdivision respectively selected by the selector mechanism (98, 99, 100), and, upon triggering of the corresponding shutter (88 through 96) the respective corresponding signalling lamp being individually switched off in response to operation of the respective shutter.
Claim 11
Dependent Claim
74 words
Image recording apparatus according to claim 1, characterized in the shutters (88 through 96) associated with the operatively disposed set of lenses and with non-exposed photographic exposure fields, being triggered in response to a manually generated film sheet change signal prior to the switching-on of the transport device (49), the television monitor (7) being switched to a brightness corresponding to a complete film exposure during the exposure of a film at such non-exposed locations.
Claim 12
Dependent Claim
34 words
Image recording apparatus according to claim 1, characterized in that the lens positioning drives (54, 55, 56) comprises respective individually operable crank mechanisms for shifting the respective lens supports to their respective active positions.
