Abstract:
A sheet stacking device including a position regulating member movable in a first direction toward a sheet edge and in a second direction away from the sheet edge, in order to regulate position of the sheet. The position regulating member includes a lock member movable between an engage position and a release position and a lock releaser that moves the lock member from the engage position to the release position. The lock releaser includes a lever member, an upper portion of the lever member including an operation portion, a pivot support that allows the lever member to tilt in the first direction and the second direction, and release mechanisms that move the lock member to the release position when the operation portion is tilted in either direction. Both the release mechanisms are provided on one side of the pivot support in the first direction or the second direction.

Claim (Index 1):
A sheet stacking device comprising:\n a stacking unit for stacking sheets; and a position regulating member held in the stacking unit and movable in a first direction toward a stacked sheet edge and in a second direction away from the sheet edge, an abutting member of the position regulating member abutting against the sheet edge to regulate position of the sheet,\n the position regulating member comprising: \n a lock member movable between an engage position engaging with an engaging portion of the stacking unit and a release position releasing engagement; and \n a lock releaser that moves the lock member from the engage position to the release position,\n the lock releaser comprising: \n a lever member, an upper portion of the lever member including an operation portion operable by a user; \n a pivot support that supports the lever member and allows the lever member to tilt in the first direction and the second direction; \n a first release mechanism cooperating with the lever member when the operation portion of the lever member is tilted in the first direction, in order to move the lock member to the release position; and \n a second release mechanism cooperating with the lever member when the operation portion of the lever member is tilted in the second direction, in order to move the lock member to the release position, \n \n wherein both the first release mechanism and the second release mechanism are provided on one side of the pivot support in the first direction or the second direction.
