The apparatus comprises a box a having a lid, an electric lamp housing c having an apertured and inclined side which may carry a diffusing sheet f to which is adapted to support a transparent photograph or the like to be viewed, and a pivotally mounted outwardly spring-urged lens holder h carrying a viewing lens i, the lamp housing and lens holder being contained in the box and the lens holder being adapted to be moved into a part of the box adjacent the lamp housing by the lid when this closes the box. As shown, the lid b is hinged to the box a and is held in the raised position by a strut m pivoted in the box. On disengaging the strut from the lid, the lens holder is turned down into the box by the lid engaging a roller k on the holder.
