Claims (1)

[Scope of utility model registration request] It is equipped with a drive roller for a thin plate whose outer circumferential surface does not actually wear out, and a spacing roller that is parallel to and closely opposed to this roller and can cause wear of the outer circumferential surface, and the distance between the respective outer circumferential surfaces of both drives makes it possible to drive only one thin plate. The device is rotatable around a predetermined axis parallel to the driving roller, one end supports the spacing roller, and the other end supports the cam. a first lever positioned in contact with the contoured surface of the lever; rotatable around the predetermined axis; one end pivotally supporting a detection roller capable of contacting the spacing roller; a second lever that is biased in a direction to narrow the gap through contact with the spacing roller; a connecting rod that is interposed between the second lever and the cam and has a variable effective length; , when the distance changes due to wear on the outer circumferential surface of the distance roller, the detection roller contacts the distance roller, thereby causing the second distance to change.
The lever is rotated, and this rotation rotates the cam via the connecting rod, and the first lever in contact with the cam is further rotated to move the spacing roller, and the respective rotations are repeated in the same manner. 1. A roller spacing adjustment device for a thin plate feeding section, characterized in that the spacing is finally adjusted to a constant value.
