In the apparatus, upper housing 1 and lower housing 2 are slidably coupled, and it is switched by sliding one of upper housing 1 and lower housing 2 with respect to the other, a closed state in which operation section 2b provided on lower housing 2 is covered by upper housing 1 and an open state in which operation section 2b is exposed. The apparatus includes opening 1c formed in a lower surface of upper housing 1, opening 2c formed in an upper surface of lower housing 2, and FPC 3 for electrically connecting wiring board 9 and wiring board 10. FPC 3 includes cover portion 3a mounted on the lower surface of upper housing 1 so as to cover opening 1c and cover portion 3b mounted on the upper surface of lower housing 2 so as to cover opening 2c. Cover portion 3a is electrically connected to wiring board 9 in upper housing 1, and cover portion 3b is electrically connected to wiring board 10 in lower housing 2. ## Claims ### Claim 1 A sliding electronic apparatus in which a first housing and a second housing laid on top of each other are coupled together so as to be able to slide relative to each other, the sliding electronic apparatus being switchable, by sliding one housing , from among the first housing and the second housing, with respect to each other, between a closed state in which an operation section provided on the second housing is covered by the first housing and an open state in which the operation section is exposed, the sliding electronic apparatus comprising: a first wiring board accommodated in the first housing; a second wiring board accommodated in the second housing; a first opening formed in an opposite surface of the first housing which lies opposite the second housing; a second opening formed in an opposite surface of the second housing which lies opposite the first housing; and a flexible printed circuit configured to electrically connect the first wiring board and the second wiring board together, wherein the flexible printed circuit includes a first cover portion mounted on the opposite surface of the first housing so as to cover the first opening, and a second cover portion mounted on the opposite surface of the second housing so as to cover the second opening, and the first cover portion is electrically connected to the first wiring board, and the second cover portion is electrically connected to the second wiring board. ### Claim 2 (depends on 1) The sliding electronic apparatus according to claim 1, wherein when the closed state is switched to the open state, the first housing moves in a first direction with respect to the second housing, and an intermediate portion of the flexible printed circuit which is located between the first cover portion and the second cover portion extends from the second cover portion in a second direction opposite to the first direction, and comprises a folded portion located away from the second cover portion in the second direction and folded toward the first direction. ### Claim 3 (depends on 2) The sliding electronic apparatus according to claim 2, wherein the folded portion is fixed to the second housing. ### Claim 4 (depends on 3) The sliding electronic apparatus according to claim 3, further comprising a fixation member for fixing the folded portion by sandwiching the folded portion between the fixation member and the second housing. ### Claim 5 (depends on 1) The sliding electronic apparatus according to claim 1, wherein the first cover portion is attached to the opposite surface of the first housing via an adhesive member, and the second cover portion is attached to the opposite surface of the second housing via the adhesive member. ### Claim 6 (depends on 5) The sliding electronic apparatus according to claim 5, wherein the adhesive member encloses the first opening and the second opening all along peripheries of the openings. ### Claim 7 (depends on 5) The sliding electronic apparatus according to claim 5, wherein the adhesive member is a double-sided adhesive tape. ### Claim 8 (depends on 1) The sliding electronic apparatus according to claim 1, further comprising a cover member configured to cover each of the first cover portion and the second cover portion. ### Claim 9 (depends on 8) The sliding electronic apparatus according to claim 8, wherein the cover member is an adhesive tape. ### Claim 10 (depends on 1) The sliding electronic apparatus according to claim 1, wherein the first cover portion is electrically connected to the first wiring board via a first connection section, and the second cover portion is electrically connected to the second wiring board via a second connection section. ### Claim 11 (depends on 10) The sliding electronic apparatus according to claim 10, wherein each of the first connection section and the second connection section comprises an independently formed flexible printed circuit. ### Claim 12 (depends on 11) The sliding electronic apparatus according to claim 11, wherein the first connection section and the first cover portion are connected together via an ACF, and the second connection section and the second cover portion are also connected together via the ACF. ### Claim 13 (depends on 1) The sliding electronic apparatus according to claim 1, wherein the flexible printed circuit comprises wiring on each of opposite surfaces thereof.
