Developing machine for ribbon-shaped photographic Layer supports, in particular roll paper

The innovation relates to a developing machine for tape-shaped photographic supports, in particular roll paper; with an attachable cassette for the supply reel and a scanning device resting on the tape, which before the inlet the end of the tape in the first treatment tank triggers a signal.

Such signaling devices are intended to indicate to the maintenance staff that a new cassette must be attached to the developing machine in order to avoid unnecessary loss of capacity.

Either a signal lamp or a bell signal is used as a signal or "earth" both types of signal used at the same time.

According to the control system, it is proposed to include a circuit in the signal To arrange the switch when removing or swiveling the. The cassette opens automatically.

So that needs. Operator 1 no special switch to operate, uai to switch off the annoying bell signal ".. Tfeiterhin is assured that after attaching a new cassette or after loading the cassette with a new storage rack the signal circuit is functional again. ■

A particularly expedient embodiment provides that the ■ Switches controlled by the cassette are only in the circuit of the Bell is arranged, i.e. that the signal lamp during after changing the cassette remains burning and only after insertion. of the beginning of the tape goes out under the scanning device. -,;

An embodiment of the ^; Firing is shown below. Hand of the drawing described!

On the input side of a roll paper developing machine that is only hinted at 1 is a cassette containing the storage angle 2 easily removable attached. - _

A scanning roller 4 mounted on a spring-loaded lever 3 rests on the paper tape emerging from the cassette mouth. The latter controls a switch 5, which is in its signal current circuit, which is formed from a signal lamp β and a bell 7. . ·

In the circuit of the bell 7 is a wide he switch. S, its push button 9 through the side wall 10 of the Entwieklungsmaschine protrudes and which is actuated by the cassette 2. As soon the end of the tape has left the scanning roller 4, -will, the Sigma! -. Circuit closed by switch 5. This lights up the Signal lamp 6 comes on and the bell starts to work.

The scanning roller 4 can be used to control the switch; ;. for the signaling device also at the same time for the control of a switch for bath dosing.
