Abstract: A temporary fixing structure includes one hooking part 14a provided on a ceiling of a compartment or a room; the other hooking part 7a that is provided on an information device 1, and is rotatably hooked on the one hooking part 14a; and a stopper holding back rotation of the information device due to self-weight moment exerted on the information device 1 in hooked condition of these hooking parts 14a and 7a in a temporally fixed posture of the information device.

Abstract: A display device holding structure includes a holding member (30) for housing and holding a display unit (400); a lid member (20) that is superposed on the holding member (30) to be united to thus forma display device (6); a support means (100, 800, 900) that is provided between the one-end side and a main body (500) of the display device (6), and supports the display device (6) openably and closably, and reversibly with respect to the display device main body (500); a lock concavity (25) provided on the other-end side of the display device (6), for locking the other-end side to the main body (500); and a lock member (150) provided in the main body (500) to be engageable/disengageable with the lock concavity (25). The display device holding structure is further arranged such that the lock concavity (25) is provided in either of the holding member (30) and the lid member (20).

Abstract: A flexible wiring board 1 includes an insulating member 12 having a conductor 11 formed therein, a reinforcing board 13 for reinforcing the insulating member 12 in the vicinity of the connection terminal 11a of the flexible wiring board 1, and a lock member 14 to be locked to a board 3 having a connector 2, with the board 3 having an opening 31 for receiving the lock member 14 fit therein in a state where the connection terminal 11a is connected and secured to the connector 2.

Abstract: A display unit includes a display mounting main body 1 secured to a ceiling to which a display is installed; the display 3 openably/closably and rotatably attached to the display mounting main body 1 through a pair of lateral rotating hinge shafts 2; and a circuit board provided as a control system of the display, wherein a wiring-relay circuit board 8 is mounted and disposed on the axis of rotation at the upper part in the extending rotating position of the display 3, and electrically connects a main circuit board disposed in the display mounting main body 1 with an LCD 4 to thereby intermediately connect wirings.
