A shutter unit includes a plurality of shutters that are grouped into groups corresponding to one of a plurality of fans, the grouped shutters being arranged beside one another and positioned on a leeward side or a windward side of the corresponding one of the plurality of fans, the grouped shutters being capable of pivoting between an open position and a closed position, the plurality of fans being for sending wind to an inside of an electronic apparatus casing; a coupling member that couples the grouped shutters together so that the grouped shutters are pivotable; and a retaining member that retains the grouped shutters in a state of being in the open position and inclined with respect to a flow direction of returning wind returning from the inside of the electronic apparatus casing toward a side of the plurality of fans.

Shutter unit and electronic apparatus

An electronic circuit unit includes an electronic circuit unit main body that is housed in a shelf, a first rotating shaft that is provided on a front side of the electronic circuit unit main body, a lever member rotatably provided about the first rotating shaft for urging the electronic-circuit-unit-main-body toward a depth side of the shelf, a second rotating shaft that is provided in the lever member and extends parallel to the first rotating shaft, a locking member rotatably provided about the second rotating shaft. When the lever member is rotated in a first direction about the first rotating shaft, the electronic circuit unit main body is moved toward a depth side of the shelf. When the lever member is rotated in a second direction, opposite to the first direction, the electronic circuit unit main body is moved toward a front side of the shelf.

Electronic circuit unit and communication device

An electronic apparatus including a housing that includes a first connector, and a printed circuit board unit that includes a printed circuit board, a second connector that is connected to the first connector at the completion of insertion of the printed circuit board into the housing, a lever that is rotatably provided for the printed circuit board, and a lock mechanism that locks the lever in a predetermined position. Wherein when the printed circuit board is inserted into the housing, the lever in a first position comes into contact with the housing, when the printed circuit board is further inserted into the housing, the lever rotates in one direction while being in contact with the housing, and when the insertion of the printed circuit board into the housing is completed, the lever is in a second position, and the lock mechanism locks the lever in the second position.

Electronic apparatus on which plug-in unit can be mounted

An electronic apparatus includes a housing having a first connector; a Plug In Unit (PIU) having a second connecter, coupled to the first connector, and inserted into the housing; a first guide mechanism (1st GM) provided on the housing and/or the PIU; a second guide mechanism (2nd GM) provided on another housing and/or the PIU and guides insertion of the PIU in cooperation with the 1st GM so that the first connector is coupled to the second connector. The 1st GM, for example, includes a guide cylinder, and the 2nd GM, for example, includes a pin inserted into the guide cylinder; a fixed cylinder surrounding the pin; and a movable member, which has a hole that passes through the fixed cylinder, and the movable member is held by the fixed cylinder to be movable in the axial direction. The guide cylinder pushes the movable member when the pin is inserted.

Electronic apparatus

A printed board to be loaded into a printed-board-receiving structure having a backboard and a guide rail, the backboard having a connector plug-in connectable to a connector on the printed board, the guide rail guiding the printed board toward the backboard and having a groove including a sloping portion, the printed board includes a sloping portion forming a projection at an end of the printed board, the projection being fittable and slidable along the groove in the guide rail.

Printed board and printed-board-receiving structure

An electronic device having an exhaust opening configured to exhaust air outside, the electronic device includes a door part configured to close the exhaust opening when the electronic device has a predetermined temperature, wherein the door part is rotated based on the own weight of the door part and a wind pressure of the air taken in the electronic device and exhausted outside the electronic device, so that the exhaust opening is closed.
