The second attachment portion 24 is attached to the right side of the second casing 5.

-Operation of full flat slide mechanism-
Next, the operation of the full flat slide mechanism 10 according to the present embodiment will be described.

First, in the superposition state shown in FIGS. 2 and 6, the pinion 30 is engaged with the upper end of the first rack 11 and the lower end of the second rack 21. The first outer pin 34 is at the upper end of the first guide hole 12, and the first inner pin 33 is at an intermediate portion of the first guide hole 12. The second outer pin 36 is at the lower end of the second guide hole 22, and the second inner pin 35 is at an intermediate portion of the second guide hole 22. In this superposed state, the first casing 3 and the second casing 5 are completely overlapped when viewed from the surface, so that the appearance is good.

Next, as shown in FIGS. 3 and 7, when the first housing 3 is moved relatively upward with respect to the second housing 5, the first inner pins 33 are moved by the pair of plate-like members 31. The first outer pin 34, the second inner pin 35, the second outer pin 36, and the pinion shaft 32 move while maintaining a predetermined interval. In other words, the first inner pin 33 and the first outer pin 34 are disposed in the first guide hole 12 so as to be slidable at a predetermined interval, and the second inner pin 35 and the second outer pin 36 are second. Since the guide holes 22 are slidably arranged at a predetermined distance from each other, the movement trajectory between the first housing 3 and the second housing 5 is stabilized, and the pinion 30 is always in the first rack 11. Since the second rack 21 and the second rack 21 are simultaneously meshed with each other, the sliding movement is reliably performed without slipping. Further, since the pair of plate-like members 31 are sandwiched between the left and right outer side walls of the first rail groove 17 and the second rail groove 27, the movement of the first rack 11 and the second rack 21 in the width direction is further increased. While reliably prevented, the pair of plate-like members 31 move smoothly.

Next, as shown in FIGS. 4 and 8, when the first casing 3 is further moved upward relative to the second casing 5, the first inner pin 33 is moved to the first guide hole 12. The second inner pin 35 is in the vicinity of the lower end of the straight portion, and the second inner pin 35 is in the vicinity of the upper end of the straight portion of the second guide hole 22.

Next, as shown in FIG. 9, when the first housing 3 is further moved upward relative to the second housing 5, the first inner pin 33 is moved to the straight portion of the first guide hole 12. By reaching the lower end and the second inner pin 35 reaching the upper end of the straight portion of the second guide hole 22, the horizontal movement of the first casing 3 in the vertical direction with respect to the second casing 5 is completed.

Next, the moving direction of the first casing 3 relative to the second casing 5 changes from the vertical direction to the thickness direction of the second casing 5. That is, the first inner pin 33 reaches the bending point 12 a of the first guide hole 12, and the second inner pin 35 reaches the bending point 22 a of the second guide hole 22. Movement in the thickness direction with respect to the housing 5 is started. At this time, the contact surface 3a of the first housing 3 and the contact surface 5a of the second housing 5 move toward each other so as to come into contact with each other. The pinion 30 is simultaneously engaged with the first switching pin 13c and the second switching pin 23c. Since the pinion 30 is engaged with the first switching pin 13c and the second switching pin 23c while rotating at a large rotation angle, the pinion 30 is smoothly moved from the horizontal movement to the vertical movement as compared with the case where the pinion 30 meshes with the rack teeth whose meshing angle is limited. Is switched to.

If the movement in the thickness direction is further continued, the full flat state shown in FIGS. 1 and 5 is obtained. At this time, since the first casing 3 and the second casing 5 do not overlap each other, the entire surfaces of the first casing 3 and the second casing 5 can be used effectively, and full By disposing the flat slide mechanism 10 in the first housing 3 and the second housing 5, the thickness at the time of full flatness can be suppressed. Moreover, since the 1st guide hole 12 and the 2nd guide hole 22 are bent and bent in the direction away from each other so that it may become an angle smaller than a right angle in bending point 12a, 22a, it opposes as it becomes full flat. Since the contact surfaces 3a and 5a approach each other, the gap between them can be made as small as possible. Furthermore, since the image can be expanded in a pseudo manner to the end portions of the contact surfaces 3a and 5a that contact each other in the full flat state by the action of the light guide element, the first display display 2 and the second display display in the full flat state. 4 screens can be displayed continuously. For this reason, since the screen can be used largely, it can be carried compactly in the polymerization state, and a large image can be displayed in the full flat state.

Therefore, according to the full flat slide mechanism 10 according to the present embodiment, the first inner pin 33, the first outer pin 34, the second inner pin 35, the second outer pin 36, and the pinion shaft 32 are connected by a pair of plate-like members 31. The first casing 3 and the second casing are slid along the first rack 11, the second rack 21, the first guide hole 12, and the second guide hole 22, respectively, while maintaining the fixed position. The body 5 can be slid smoothly and relatively, and the surfaces of the first casing 3 and the second casing 5 can be effectively used while suppressing the thickness.
