Abstract: There is provided a recording/reproducing apparatus having a simple and inexpensive structure of providing a protrusion at a front side end of a tray for placing a storage medium and transporting the storage medium inside and outside of the recording/reproducing apparatus; providing an engaging rib at the rear side of an open/close door mounted on a casing, the door pivotably opening and closing together with reciprocating movement of the tray; the protrusion and the engaging rib being engaged with each other when the open/close door is in a closed state, and thereby the closed state of the open/close door can be maintained in response to a stress which acts in a direction in which the open/close door is opened from the outside of the recording/reproducing apparatus.

Abstract: To provide an electronic device with a built-in disk device including a disk device and disk device control substrate arranged side by side capable of reducing problems caused when a flexible flat cable connected to a pickup section which is a movable section touches other members inside the device and reducing a load applied to a connection of the flexible flat cable. In an FFC 23 provided with a slack portion 23a to absorb the moving distance of a pickup section 11a, the slack portion 23a is provided with a bending section 23b and bending section 23c bent in mutually opposite curving directions and the bending section 23b is stopped by an L-figured stopper 40 to thereby prevent a connection 12a from being affected by sliding of the pickup section 11a (load caused by the movement of the FFC near the connection).
