FILM LEADER TRANSFER ROLLER OF PROCESSING RACK FOR AUTOMATIC DEVELOPING DEVICE

摘要

The present invention is a film of a processing rack of an automatic film developing apparatus, comprising a sprocket which is driven and rotated from the outside, means for conveying the film leader along a predetermined path by rotation of the sprocket, and means for guiding and supporting the film leader conveying means. A leader feed mechanism, which relates to a film reader feed mechanism of a processing rack of an automatic film developing apparatus, wherein the film leader 25 is a chain 24. The chain 24 is composed of a plurality of unit body 40 and a plurality of pins 48, the unit body 40 of the two pin-shaped inner portion 42 and the inner portion 42 of the opposite facing each other and extending in parallel A connecting portion 47 connecting the upper portion, two plate-shaped outer portions 41 which are spaced apart from each other and larger than the gap between the inner portions 42 and facing each other in parallel to the inner portion 42, connect the outer portions and the inner portions. It is composed of two intermediate portions 43, a projection 46 is formed in the center of the upper surface of the connecting portion 47, the inner portion 42 is formed with openings 44 that vertically penetrate both inner portions, and the outer portion ( 41 are formed with openings 44 penetrating both inner portions vertically, and outer portions 41 are formed with openings 45 penetrating both outer portions vertically, the openings 44 and 45 having the same outer diameter. Having a diameter, an inner portion 42 of one unit is inserted between the outer portions 41 of adjacent units The pins 48 are inserted into the openings 44 and 45.
