Abstract
A developing tray for feeding a sheet of positive material and a sheet of negative material through a bath of developer, above which bath a lid is mounted for reducing the evaporation of developer, feed rollers being provided at both the input opening and the output opening, and whereby the bottom of the tray is provided with ribs extending substantially in the feed direction of the sheets. The length of the developing tray is primarily determined by the fact that a predetermined developing time is necessary. Furthermore the material in question must be fed through the bath at a predetermined speed in order to ensure a predetermined turbulence in the developer. The bath must therefore be of a certain minimum length. A problem is therefore caused by small sheets unable to reach the rollers at the output opening. The same developing tray also can be used in connection with light sensitive materials of a small size, e.g. A5-size, by providing extra openings in the lid, spaced from the rollers at the output opening in such a manner that the sheets of light sensitive material can reach these rollers.
