with respect to a base and a second rotation support portion formed to be horizontally rotatable with respect to the base independently of the first rotation support portion, for horizontally rotating a display screen portion by rotating at least either the first rotation support portion or the second rotation support portion. ## Claims ### Claim 1 A display screen turning apparatus comprising: a base; a first rotation support portion provided separately from said base for supporting a display screen portion and formed to be horizontally rotatable with respect to said base; a second rotation support portion provided separately from said base for supporting said display screen portion and formed to be horizontally rotatable with respect to said base independently of said first rotation support portion, for horizontally rotating said display screen portion by rotating at least either said first rotation support portion or said second rotation support portion; at least either said first rotation support portion or said second rotation support portion includes a slide member formed to horizontally slide with respect to said base, and a support member, supporting said display screen portion, formed to be horizontally rotatable with respect to said slide member, wherein said base includes a guide portion formed to guide sliding of said slide member and inhibit said slide member from floating up from said base when said slide member horizontally slides, said slide member includes a first slide member, constituting said first rotation support portion, formed to horizontally slide with respect to said base and a second slide member, constituting said second rotation support portion, formed to horizontally slide with respect to said base, said support member includes a first support member, constituting said first rotation support portion along with said first slide member, formed to be horizontally rotatable with respect to said first slide member and a second support member, constituting said second rotation support portion along with said second slide member, formed to be horizontally rotatable with respect to said second slide member, said guide portion is formed to guide rotation of said first slide member and said second slide member when said first slide member and said second slide member horizontally rotate respectively, said first slide member has a first rotation control portion controlling rotation of said first slide member by coming into contact with said guide portion when said first slide member rotates with respect to said base portion, and said second slide member has a second rotation control portion controlling rotation of said second slide member by coming into contact with said guide portion when said second slide member rotates with respect to said base. ### Claim 2 (depends on 1) The display screen turning apparatus according to claim 1, wherein said first support member is formed to support a first horizontal side of said display screen portion as viewed from the front side and to horizontally rotate with respect to said first slide member following movement of said second slide member, and said second support member is formed to support a second horizontal side of said display screen portion as viewed from the front side and to horizontally rotate with respect to said second slide member following movement of said first slide member. ### Claim 3 (depends on 1) The display screen turning apparatus according to claim 1, wherein said first rotation control portion and said second rotation control portion are integrally provided on both ends of side portions of said first slide member and said second slide member guided by said guide portion respectively. ### Claim 4 (depends on 1) The display screen turning apparatus according to claim 1, wherein said guide portion of said base is formed to inhibit said first slide member and said second slide member from floating up from said base respectively. ### Claim 5 (depends on 3) The display screen turning apparatus according to claim 3, wherein said guided side portions of said first slide member and said second slide member are arcuately formed respectively. ### Claim 6 (depends on 5) The display screen turning apparatus according to claim 5, wherein said first rotation control portion is formed to protrude in the radial direction of the arc formed by said side portion of said first slide member, and said second rotation control portion is formed to protrude in the radial direction of the arc formed by said side portion of said second slide member. ### Claim 7 (depends on 1) The display screen turning apparatus according to claim 1, wherein said guide portion is integrally formed on said base. ### Claim 8 (depends on 1) The display screen turning apparatus according to claim 1, wherein said first slide member and said second slide member have projecting portions on surfaces coming into contact with said base respectively, and are formed to horizontally rotate when said projecting portions slide with respect to said base. ### Claim 9 (depends on 8) The display screen turning apparatus according to claim 8, wherein each of said first slide member and said second slide member has a plurality of said projecting portions, and said plurality of projecting portions have substantially identical heights respectively. ### Claim 10 (depends on 1) The display screen turning apparatus according to claim 1, wherein said base includes a disengagement preventing portion preventing disengagement of said first slide member and said second slide member when the display screen turning apparatus is operatively configured and supporting the display screen portion. ### Claim 11 (depends on 10) The display screen turning apparatus according to claim 10, wherein said disengagement preventing portion is provided on said base to vertically protrude upward from the upper surface of said base and formed to prevent disengagement of said first slide member by coming into contact with said first slide member when said first slide member rotates and to prevent disengagement of said second slide member by coming into contact with said second slide member when said second slide member rotates. ### Claim 12 (depends on 11) The display screen turning apparatus according to claim 11, wherein said disengagement preventing portion is arranged on the base between facing sides of said first slide member and said second slide member. ### Claim 13 (depends on 11) The display screen turning apparatus according to claim 11, wherein said disengagement preventing portion comprises a number of discrete portions each having a circular shape in a plan view of the upper surface of said base. ### Claim 14 (depends on 10) The display screen turning apparatus according to claim 10, wherein said disengagement preventing portion is integrally provided on said base. ### Claim 15 (depends on 1) The display screen turning apparatus according to claim 1, wherein said first slide member and said second slide member have side portions vertically folded upward respectively. ### Claim 16 (depends on 1) The display screen turning apparatus according to claim 1, wherein said first support member and said second support member are formed to support said display screen portion to be anteroposteriorly rotatable respectively.
