Description

Esist bei tragbaren Lesegeräten, insbesondere bei kofferartigen Lesiegeräten, von Nachteil, daß die Projektionsfläche, gewöhnlich ein auf den Tisch gelegtes Blatt Papier, leicht verrutscht; das projizierte Bild kommt dann zum Teil auf die dunkle Tischfläche zu liegen. Das gleiche ist der Fall, wenn das Papier zwar unverändert liegenbleibt, aber das Gerät verschoben wird.It is with portable readers, especially suitcase-like readers, disadvantageous that the projection surface, usually a sheet of paper placed on the table Paper, slipped easily; the projected image then comes in part on the dark To lie on the table. The same is the case if the paper is unchanged remains, but the device is moved.

Gemäß der Erfindung, die an einem Ausführungsheispiel erläutert ist, das in der Abbildung in perspektivischer Ansicht schematisch dargestellt ist, läßt sich dieser Nachteil dadurch vermeiden, daß ein Teil der Wandung des Gerätes, beispielsweise die vordere Wandung i, herausklappbar und als vorzugsweise waagerechte Lesefläche ausgebildet ist. Vorteilhaft ist es dabei, die Lesefläche, wie es in der Abbi ' ldung wiedergegeben ist, aus zwei etwa gelenkig (bei 4) miteinander verbundenen Teilen 2,3 bestehen zu lassen; dadurch ist die Lesefläche unabhängige von der Größe der herausgeklappten Kofferwandung. Ein weiterer Vorteil läßt sich dadurch erzielen, daß die herausklappbare Wandung doppelwandig, beispielsweise als Vorratsbehälter 5 für Filnie o. dgl., ausgebildet ist.According to the invention, which is explained using an exemplary embodiment, which is shown schematically in the figure in a perspective view, can avoid this disadvantage that part of the wall of the device, for example the front wall i, can be folded out and used as a preferably horizontal reading surface is trained. It is advantageous to use the reading area, as shown in the illustration ldung is shown, from two approximately articulated (at 4) connected to one another To let parts 2,3 exist; this means that the reading area is independent of its size the unfolded case wall. Another advantage can be achieved by that the fold-out wall is double-walled, for example as a storage container 5 for Filnie o. The like., Is formed.
