Abstract
Abstract A boundary display device is used in a photographic printer performing so-called division-printing by which partial prints are produced from an image frame of a negative film to construct a composite greatly-enlarged print. The boundary display device comprises a transparent plate and lines which represent the boundaries of areas into which a scene of a film frame is nominally divided. The transparent plate is placed in an opening of a film carrier of the printer so as to view how the scene is divided prior to the division-printing. Based on the viewing, the position of the film in the opening is moved slightly if necessary.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
89 words
A boundary display device for a photographic printer which has a carrier holding an original and performs division-printing in which the original is nominally divided into a plurality of areas to make a plurality of enlarged partial prints from the original, each of enlarged partial prints corresponding to one area of the nominally divided original, and the carrier having an opening for exposure of division-printing, comprising: a transparent plate placeable on the original; and a plurality of lines provided on said transparent plate which represent boundaries of the areas.
Claim 2
Dependent Claim
89 words
A boundary display device for a photographic printer which has a carrier holding an original and performs division-printing in which the original is nominally divided into a plurality of areas to make a plurality of enlarged partial prints from the original, each of enlarged partial prints corresponding to one area of the nominally divided original, and the carrier having an opening for exposure of division-printing, comprising: a transparent plate placeable on the original; and a plurality of lines provided on said transparent plate which represent boundaries of the areas.
Claim 3
Dependent Claim
19 words
A boundary display device as claimed in claim 1, wherein said transparent plate is detachably fitted in the opening.
Claim 4
Dependent Claim
37 words
A boundary display device as claimed in claim 2, wherein a gripping means to be held with fingers is provided on one end of said transparent plate so as to place said transparent plate in the opening.
Claim 5
Dependent Claim
42 words
A boundary display device as claimed in claim 1, wherein said transparent plate is pivotably provided on the carrier and is movable away from the opening at a standing position so as not to disturb the exposure when the division-printing is performed.
Claim 6
Dependent Claim
38 words
A boundary display device as claimed in claim 1, wherein said transparent plate is slidably provided in the carrier and is movable away from the opening so as not to disturb the exposure when the division-printing is performed.
Claim 7
Dependent Claim
33 words
A boundary display device as claimed in claim 4 or 5, wherein said transparent plate is provided with a holding means to be held with fingers so as to move said transparent plate.
Claim 8
Dependent Claim
64 words
A boundary display device as claimed in claim 1, wherein the carrier comprises a holder for holding the original and being movable back and forth along a first axis, a table slidably supporting the holder and being movable back and forth along a second axis perpendicular to the first axis, and a mask which is provided with the opening to press the original flat.
