Abstract

Provided is a sheet material feeding device that achieves a reduction in power consumption, has improved durability, and transports a sheet material with high accuracy. This sheet material feeding device, which transports a sheet material clamped by a first roll and a second roll, is equipped with a release mechanism for releasing the clamped sheet material, the release mechanism having an eccentric cam, an eccentric cam bearing arranged along a side surface of the eccentric cam, a guide arranged so as to be able to contact the eccentric cam bearing, and a block arranged so as to be able to contact the guide and connected to an upper roll support member. The release mechanism causes the eccentric cam to rotate and moves the guide in a horizontal direction relative to the block by means of the eccentric cam bearing, thereby causing the upper roll support member connected to the block to move in the vertical direction.
