A cam projection sliding in a cam slot of an arm causes the arm to proceed to an arm when a shutter is in the closed position or the open position and to recede from the arm when the shutter is sliding between the open position and the closed position. A spring is thereby considerably displaced, providing a satisfactory operation of the shutter.

Media playback apparatus and shutter mechanism

An arm () is provided with protrusions () disposed between a spring () and the arm () and biasing the spring () away from a shutter () when the shutter () is disposed at either one of two positions, a closed position and an open position. This prevents natural vibration of the spring () due to extension of the spring (), thereby preventing noise.

A through-hole of a flat spring has a shape that defines an opening area larger than the cross-sectional area of an end segment of a shaft and is subject to contact with the rotating end segment. A through-hole of a plate has an opening area larger than the cross-sectional area of the end segment and smaller than the opening area of the through-hole. The end segment is inserted through the through-hole and the through-hole and is swaged to form a space between the through-hole and the end segment, and the space is filled with grease.

Hinge mechanism and electronic device provided with the same

An audio transmission unitis placed on a surface side of a panel unitwhere a displayis provided, and transmits an audio signal in a direction almost perpendicular to the surface of the display. When a viewer sitting in a seat behind a front seatturns the displayto be faced toward him/her, the audio transmission unitis directed in front of the viewer's eyes, so that stable audio signal can be received in the side of the headphone worn on the head of the viewer.

Panel device

In a state where a panel unitis held at a storing angle with a projecting portionof a click platefitted in a recessed portionof a bracketthe back side of the projecting portionand a pressing pieceof a friction platedo not abut on each other, so that only a reaction force of the click plateserves as a resistance. When the panel unitstarts turning, the projecting portionabuts on the pressing piecethrough the elastic deformation at the time when the projecting portionmoves out of the recessed portionto get onto a sliding surfaceso that a sliding resistance is obtained from the reaction forces of the click plateand the friction plateafter abutment.

Hinge mechanism and panel apparatus

A plate springis subjected to folding at a fold portionto form integrally a plate spring portionand a stress relief portionand a distal end of a rotary shaftis secured to a caulking hole of the stress relief portionby caulking.

Hinge mechanism, and monitor opening and closing mechanism

First and second FPC fixing membersare fixed within a bosson a second axis Y, and one end of the second memberprojects to the back of a hinge base. An FPC wiring fixing sectionis fixed on the back of the baseon a first axis X. The fixing members pass an FPCfrom the baseside to the side of a monitorto hold the FPC linearly on the axis Y, and are turned integrally with a monitor mounting base. The fixing members curve outside the axis Y the FPCthat is led out in the direction orthogonal to the axis Y from the one end on the baseside of the second memberto have a deflection allowance, and fix the FPC to the base

FPC fixing structure for two-axis hinge mechanism

A platefastened to a D-cut sectionof a rotation shaftby caulking has an engaging holeprovided therethrough. Further, a positioning protrusionfor engaging the engaging holeis provided in a leaf springsandwiched between the rotation shaftand the plate. The inclination &#x3b8;of the leaf springmade by the amount of a clearance B between the engaging holeand the positioning protrusionthat are distant from the rotation central axis X is smaller than the inclination &#x3b8;made by the amount of a clearance A between the D-cut sectionand the straight portionthat are close to the rotation central axis X. Thus, the backlash in the rotation direction of the leaf springcan be reduced by providing the positioning protrusionand the engaging hole
