Filed: 1978-03-14
Abstract: PURPOSE: To convey photosensitive materials without creasing, meandering, etc. by automatically correcting the inclination of a clip occuring when a speed difference is produced between two parallel cycling conveying belts.  
     CONSTITUTION: A clip 2 makes contact to the inner and outer edges of a belt 3a at a distance α smaller than the width of a conveying belt 3a and engages the belt 3a by way of an engaging means 4a which is detained to the belt 3a by detaining pawls 5a, 6a, of which the spacing width between the contact points is larger than the width of the belt 3a. The other end of the clip 2 is engaged to a belt 3b which is parallel with the belt 3a by way of a similar engaging means 4b. Hence, when the clip 2 is engaged, the belts 3a, 3b go toward the direction where they incline at an angle θ in 8-form. when the conveying speed of the belt 3a becomes larger than that of the belt 3b, the means 4a inclines and when the inclination angle θ of the belt 3a increases, the means 4a is automatically restored by the repulsion force generated because of the distances β>α, whereby the inclination of the clip 2 is automatically corrected. As a result, the creasing, meandering, etc. of the photosensitive material P conveyed via the clip 2 are prevented.
