Shelf plate adapted for mounting on an office machine

摘要

A shelf plate is adapted for use with an office machine having an insertion slot for receiving the plate. The plate is formed of a synthetic resin in a generally planar surface and includes integrally formed, laterally offset leaf spring portions that extend from each side of the plate in a direction opposite to that in which the plate is normally inserted into the office machine. Each of the leaf spring portions includes on its top surface a groove defined by a first and a second stepped portion that is adapted to engage locking edges on the insertion slot in the framework of the office machine. The inherent elasticity of the leaf spring portions biases the groove into engagement with the locking edge. A force may be exerted on the extending free ends of the leaf spring portions to disengage the groove from the locking edge for removal of the shelf plate from the office machine.
