A PIU plug-in/plug-off mechanism for an electronic apparatus, which is capable of efficiently applying a force required for a plugging-in/off operation of connectors to a printed board by pressing a portion of the printed board close to a backplane. An operating handle of a card lever is turned counterclockwise to thereby bring a push pin into abutment with a rear edge of an open recess. When the card lever is further turned in this state, a pressing force for moving a plug-in unit in the insertion direction acts on an engaging member via an arm. This starts fitting the printed board into a plug-in connector without causing warping of the printed board.

What is claimed is: 1. A PIU plug-in/plug-off mechanism for an electronic apparatus, which enables a printed board to be plugged into and out of a bookshelf-type electronic apparatus, comprising: a shelf having a rear side having a backplane on which the printed board is mounted, and sidewalls each having an upper edge which defines a front face; a card lever that is supported on the front face of said shelf and is turned for plugging in/out the printed board; an arm that has a base part at one end connected to said card lever and a free end at the other end formed to extend toward said backplane of said shelf; and an engaging member that is provided at a leading end of the printed board such that said engaging member is engaged with said free end of said arm in a state where the printed board is inserted in said shelf, wherein when said card lever is turned in one direction, said free end of said arm is brought into engagement with said engaging member; when said card lever is further turned, the printed board is pushed toward said backplane within said shelf by said free end of said arm via said engaging member; and when said card lever is turned in another direction, the printed board is pushed away from said backplane within said shelf by said free end of said arm via said engaging member. 2. The PIU plug-in/plug-off mechanism according to claim 1, wherein said card lever comprises a first resilient member for applying a turning force in the other direction, and wherein during insertion of the printed board from the front face of said shelf, or removed of the printed board, said card lever is held in parallel with said arm. 3. The PIU plug-in/plug-off mechanism according to claim 1, wherein said engaging member has an open recess formed to have a predetermined depth for engagement with said free end of said arm, and wherein when said card lever is further turned in the other direction in a state in which the printed board is plugged off a connector on said backplane, said free end of said arm is disengaged from the open recess. 4. The PIU plug-in/plug-off mechanism according to claim 3, wherein said arm comprises a guide pin that is guided by a guide groove formed at a location close to said backplane of said shelf, and a push pin for engagement in the open recess, both provided in said free end thereof and wherein when said arm is pressed in a direction in which said arm extends, said push pin is guided to a bottom part of the open recess. 5. The PIU plug-in/plug-off mechanism according to claim 4, wherein said engaging member is configured such that when a force acting in a direction away from said backplane is applied to the printed board, said push pin is brought into abutment with a front edge of the open recess. 6. The PIU plug-in/plug-off mechanism according to claim 4, wherein the guide groove comprises a retreat passage for causing said guide pin to retreat therethrough, and wherein when said card lever is turned in the one direction after insertion of the printed board into said shelf and before engagement of said engaging member with said push pin, said guide pin is guided into the retreat passage. 7. The PIU plug-in/plug-off mechanism according to claim 4, wherein said arm comprises a second resilient member for generating a turning force in a direction of pushing said free end of said arm into the open recess, and wherein said push pin is pushed against said engaging member in a state of the printed board having been inserted in said shelf. 8. The PIU plug-in/plug-off mechanism according to claim 1, wherein said card lever comprises a lock lever for locking an operating handle thereof in a disabled state, and wherein when said card lever is turned until the printed board is plugged into the connector on said backplane, said lock lever is brought into a locking state. 9. The PIU plug-in/plug-off mechanism according to claim 8, wherein when said card lever is turned through a predetermined angle in the one direction, said lock lever is brought into engagement with a lock receiving part formed in a holder of said card lever, to thereby lock turning of said card lever.
