Abstract:
1. A substrate unit to be inserted and installed in a substrate housing shelf of an electronic device, comprising: a printed board; a connector wiring connected to the printed board; a front panel provided on the printed board on a front face side of the shelf; a lever assisted insertion device including a lever member that engages with a front frame of the shelf before a fully inserted position at which the connector is connected to a connector on the shelf side, to form a leverage fulcrum on the front frame, in which the lever member is constituted such that a force that an operator applies to the lever member is transmitted to the front panel via a point of application with respect to the fulcrum, thereby inserting the substrate unit up to the fully inserted position, and a buffering device that abuts against the front frame of the shelf within a depth range of the front panel before an operation start position at which the lever member of the lever assisted insertion device engages with the front frame of the shelf, to absorb impact of the substrate unit at the time of insertion.
