Automatic photographic developing machine

Abstract

An automatic photographic developing machine has easily detachable top turn guides each provided with a locking mechanism that allows any incompletely set top turn guide to be pushed to an accurate set position and locked. The top turn guides are detachably mounted between handles provided at tops of racks hung in treating tanks. Each top turn guide has a support piece to be supported on top surfaces of the handles, and a pair of front and rear control pieces. Each control piece has a protrusion. The handles are formed with recesses. Each top turn guide is inserted between a pair of adjacent handles with the control pieces deformed inwardly by gripping them from opposite sides. The control pieces are released with the support piece supported on the top surfaces of the handles to let the protrusions engage in the recesses. The top turn guide is thus locked in position. Even if a top turn guide is incompletely set, it is pressed down by a pusher provided on a top cover to its predetermined set position with high accuracy by closing the top cover.
