A bunch sheet depository is described. The depository comprises: a pressure plate for pressing on a bunch of sheets; a picker aligned with the pressure plate and arranged to remove sheets individually from the bunch of sheets; a link arm including (i) a pivot, (ii) an urging portion coupled to the pressure plate and (iii) a resilient member; and an actuator coupled to the resilient member. The actuator is operable, when actuated, to move the resilient member to rotate the link arm about the pivot and thereby cause compression of the bunch of sheets by the pressure plate using a force from the resilient member that reduces as the resilient member relaxes in response to the pressure plate moving as sheets are removed from the bunch of sheets. 1. A bunch sheet depository comprising:a pressure plate for pressing on a bunch of sheets;a picker aligned with the pressure plate and arranged to remove sheets individually from the bunch of sheets;a link arm including (i) a pivot, (ii) an urging portion coupled to the pressure plate and (iii) a resilient member; andan actuator coupled to the resilient member and operable, when actuated, to move the resilient member to rotate the link arm about the pivot and thereby cause compression of the bunch of sheets by the pressure plate using a force from the resilient member that reduces as the resilient member relaxes in response to the pressure plate moving as sheets are removed from the bunch of sheets.2. A depository according to claim 1 , wherein the pressure plate receives a bunch of sheets on an upper surface thereof.3. A depository according to claim 1 , wherein the picker picks individual sheets from a top of the bunch.4. A depository according to claim 1 , wherein the bunch loader further comprises a sheet transport arrangement.5. A depository according to claim 4 , wherein the sheet transport arrangement comprises a chassis and a pivot shaft mounted to the chassis claim 4 , and the urging portion and the pressure plate are ...
