Structure of mounting flexible wiring board

#This invention relates to a structure of mounting a flexible wiring board (flexible circuit board) mounted, for example, on an optical disk device.

#In a disk device for an optical disk such as a compact disk (CD), a spindle motor for rotating the optical disk, as well as an optical pickup for optically reading information recorded in the rotating optical disk, is mounted on a feed chassis pivotally mounted on a device body. In this case, the optical pickup need to be moved in a direction of a radius of the optical disk, and therefore is mounted on a slider which is reciprocally movable in this direction.

#In order to feed signals detected by the optical pickup and also to drive and control an actuator contained in the optical pickup, the optical pickup is connected to a circuit board by a long flexible wiring board, and terminals of the optical pickup are electrically connected to corresponding terminals of the circuit board, respectively. This flexible wiring board is a long strap-like member, and this member is disposed in a generally S-shaped curved condition, and has a length to sufficiently cover the range of movement of the slider.

#The above objects and advantages of the present invention will become more apparent by describing in detail preferred exemplary embodiments thereof with reference to the accompanying drawings, wherein:

#FIG. 1 is a side-elevational view of a flexible wiring board-mounting structure according to a preferred embodiment of the present invention;

#FIG. 2 is a side-elevational view showing the flexible wiring board-mounting structure according to the preferred embodiment of the present invention; and

#A preferred embodiment of a flexible wiring board-mounting structure of the present invention will now be described in detail with reference to the accompanying drawings.

#FIGS. 1 and 2 are a side-elevational view showing the embodiment of the flexible wiring board-mounting structure of the invention, and FIG. 3 is a view as seen from the line A-A of FIG. 1.

#The flexible wiring board-mounting structure 1, shown in FIG. 1, is mounted, for example, on a disk device which drives and rotates an optical disk (such as a compact disk (CD), a CR-ROM, a CR-R, a CD-WR, a DVD-R and a DVD-WR), and has the function of reading information recorded in this optical disk (and further has, in some cases, the function of writing information on the optical disk).
