ABSTRACT:
Device for transferring the film holders in a film developer which was described by the Italian patent application No. 45731 A/82 of the same Applicant. Such a device is constituted by an arm (1) formed by two rods, a first fixed rod (2) which is applied in the same manner and is actuated by the same means provided to actuate the transferring arm of the above film developer, and a second movable rod (3) which is longitudinally slidable with respect to said fixed rod (2) and may assume two operating positions, a first position in which all the fork elements (21-31) which are arranged on both rods are equally spaced each other, so as to be able to catch a respective film holder (7) and to transfer it for each time in which said arm (1) is actuated.
When the second movable rod (3) is shifted in its second operating position, the fork elements (31) which are disposed on said second movable rod (3) are so shifted as to avoid the respective film holders (7) to be caught and transferred, wherein said arm is cyclically actuated within time periods which are submultiple of the time period in which the development stage is carried out.
The movable rod (2) is provided with a pin (32), which bears against a deviation lever (33) having two operating positions when the arm (1) is shifted, in such a manner as to shift said movable rod (2) in its two operating positions.
