Description

Papierhalter für photographische Vergrößerungsgeräte Die Erfindung geht aus von einem Papierhalter für photographische Vergrößerungsgeräte mit einem Randabdeckwinkel, auf dessen Schenkeln zwei die Abdeckung ergänzende Maskenbänder nach je einer Maßteilung verschiebbar sind.Paper holder for photographic enlargers The invention is based on a paper holder for photographic enlargers with a Edge cover bracket, on the legs of which two masking tapes complement the cover are shiftable according to a graduation.

Um bei einem solchen Papierhalter die Möglichkeit zu schaffen, verschiedene Randbreiten einstellen zu können, ohne daß man die gewünschte Randbreite für die Einstellung der Masken1iänder von Fall zu Fall durch Rechnung berücksichtigen muß, ist gemäß der Erfindung die Anordnung so getroffen, daß der Abdeckwinkel nach einer die Breite der Randabdeckung angebenden Teihing diagonal verschiebbar geführt ist und daß die auf den Schenkeln des Abdeckwinkels angebrachten Maßteilungen für die Maskenbänder ihrerseits zu den Schenkeln des Abdeckwinkels derart durch Stiftschlitzführungen verschiebbar sind, daß sie sich bei der Diagonalv erschiebung des Abdeckwinkels zwangsläufig um den doppelten Betrag zu den Winkelschenkeln längs verschieben.In order to create the possibility for such a paper holder, different To be able to adjust border widths without having to set the desired border width for the The setting of the mask countries must be taken into account on a case-by-case basis by means of an invoice, according to the invention, the arrangement is made so that the cover bracket after a the width of the edge cover indicating Teihing is guided diagonally displaceable and that the graduations attached to the legs of the cover bracket for the Mask straps in turn to the legs of the cover bracket in such a way through pin slot guides are displaceable that they are in the Diagonalv displacement of the cover angle inevitably move lengthways by twice the amount to the angle legs.

Ein Ausführungsbeispiel des Erfindungsgegenstandes ist in der Zeichnung als Draufsicht dargestellt.An embodiment of the subject matter of the invention is shown in the drawing shown as a top view.

An dem Anschlagwinkel i, dessen Innenkannten 15, 16 zur festen Anlage des Vergrößerungspapiers dienen, ist der mittels Scharnierbänder 6 aufklappbare Abdeckwinkel 2 angeordnet, und zwar sind die Scharnierbänder 6 an der Schlitzleiste 3 angebracht, die ihrerseits durch Schlitzführungen d. diagonal zu dem Anschlagwinkel i verschiebbar ist. Der Abdeckwinkel 2 trägt zwei Bandskalen 7, 8, welche einerseits auf den Winkelschenkeln des Winkels 2 in Längsschlitzen 9, io und anderseits in dem Anschlagwinkel i in den Schlitzen 11, 12 geführt sind, die zu den Schlitzführungen 4 senkrecht verlaufen.At the stop bracket i, the inner edges 15, 16 of which for a fixed contact of the enlargement paper, the one that can be opened by means of hinge straps 6 Cover bracket 2 arranged, namely the hinge strips 6 are on the slotted strip 3 attached, which in turn by slot guides d. diagonal to the stop bracket i can be moved. The cover bracket 2 carries two tape scales 7, 8, which on the one hand on the angle legs of the angle 2 in longitudinal slots 9, io and on the other hand in the stop bracket i are guided in the slots 11, 12 that lead to the slot guides 4 run vertically.

Wird nun der mit der Schlitzleiste 3 verbundene Abdeckwinkel 2 mittels des Handknopfes 5 zwecks Randeinstellung verstellt, wobei auf der Randskala 13 die Randbreite in Millimeter abzulesen ist, so werden die zwei Bandskalen 7, ä infolge der Schlitzführungen 9, 11, I o, 12 zwangsläufig um das Doppelte verschoben. Es wird somit die beiderseitige Randbreite für die Einstellung der Abdeckbänder 14 durch diese Verschiebung der Bandskalen 7, 8 jeweils zwangsläufig berücksichtigt.If now the cover bracket 2 connected to the slot strip 3 by means of of the hand knob 5 adjusted for the purpose of setting the margin, on the marginal scale 13 the Edge width can be read in millimeters, the two tape scales 7, ä as a result the slot guides 9, 11, I o, 12 inevitably shifted by twice. It thus becomes the edge width on both sides for the adjustment of the cover strips 14 by this displacement of the tape scales 7, 8 in each case inevitably taken into account.
