  Then, the center of the slide plate portion 16 formed of this plate material is bent and protruded toward the slide surface 12A so as to be engaged with an opening portion 20 of an intervening auxiliary plate portion 19 described later. The center of the curved portion to be joined is further curved to form a small protrusion, and an elastic engagement protrusion 15 is formed on the slide plate portion 16, and the slide plate portion 16 is connected to the first connecting portion 12. When the second connecting portion 13 is slidably engaged, the first connecting portion 12 and the second connecting portion 13 are interposed between the first connecting portion 12 and the second connecting portion 13 together with the (relative) sliding movement of the second connecting portion 13. The engaging projection 15 is slidably moved while being pressed against the sliding surface 12A of the portion 12.

  Further, an engagement hole 17 that engages and holds the sliding position of the second connecting portion 13 with respect to the first connecting portion 12 by engaging with the engaging protrusion 15 is formed in the slide surface 12A of the first connecting portion 12. (See FIGS. 6 and 7). In this embodiment, the engagement holes 17 are formed at two locations with a gap between the slide surfaces 12A, and the engagement projections 15 are engaged with the engagement holes 17 at the two locations. And a click engagement state at the slide release position.

  That is, in the present embodiment, as described above, the horizontal bent edges of the second connecting portion 13 are engaged between the guide portions 14 in which the tips of the both side edges of the first connecting portion 12 serving as guide rails are folded inward. The tap portion 18 for attaching to the second member 2 is provided on the main portion of the second connecting portion 13 raised from the open portion of the first connecting portion 12, and the tap portion 18 is provided on the overlapping side of the first connecting portion 12. A slide plate portion 16 having an engagement protrusion 15 is provided between the engagement portions 18 as an engagement portion 18, and the engagement protrusion 15 of the slide plate portion 16 is connected to the interposition auxiliary plate portion 19. The engaging protrusion 15 is projected from the opening 20 by engaging with the opening 20, and the slide plate portion 16 and the intervening auxiliary plate portion 19 are caused by this engagement and the folded piece at the end of the interposition auxiliary plate portion 19. The slide plate portion 16 and the intervening auxiliary plate portion 19 are overlapped on the overlapping side of the second connecting portion 13 and integrated with the slide. It is configured to retaining engagement omission by sliding insertion from the end of the first connection part 1.

  Accordingly, the first connecting portion 12 and the second connecting portion 13 can also be formed by pressing from a plate material, and the slide plate portion 16, the engaging protrusion 15, the engaging hole 17, and the intervening auxiliary plate portion 19 are also formed by pressing. Because it is possible, the number of parts is small and the manufacture is easy. As described above, for example, the second connecting part 13 with the slide plate part 16 arranged on the back side between the one end of the first connecting part 12 and the guide part 14 and the interposition auxiliary It can be assembled simply by superposing the plate portion 19 and slidingly inserting and engaging it, and it is easy to manufacture at a low cost and extremely excellent in mass productivity.

  Further, in this embodiment, at the time of sliding, the engaging projection 15 of the slide plate portion 16 not only slides on the slide surface 12A via the opening 20, but also the intervening auxiliary plate portion 19 contacts the slide surface 12A. Therefore, slide resistance due to the intervening auxiliary plate portion 19 is further generated. Therefore, even if the engaging protrusion 15 is not strongly pressed against the sliding surface 12A, sliding resistance is caused by interposing the auxiliary auxiliary plate portion 19, so that sufficient sliding resistance that can realize a free stop can be secured. Since the contact point 15 is not a single pressure contact, even if the slide surface 12A is not sufficiently smooth, there are many or multiple or dispersed parts where slide resistance occurs, so the total slide resistance is increased to achieve a free stop. Even if the engagement projection 15 does not need to be pressed strongly, the engagement projection 15 can be moved away from the engagement hole 17 and slid. A strong force is not required, and in this sense, the sliding movement can be performed smoothly.

  Next, the operation of this embodiment in which the connecting device R is configured as described above will be described.

  In the state where the first member 1 and the second member 2 are superposed, the operation unit 4 (first operation unit 4A) is not exposed, and only the display unit 5 (first display unit 5A) is exposed. (See FIG. 1).

  When operating the functions available on the first display unit 5A (when using the vertical screen function), as shown in FIG. 3, the front and rear of the first member 1 with respect to the first member 1 via the slide device unit S When the second member 2 is slid in the direction (extending direction in the length direction) (the connection base 3 (first connection portion 12) is slid relative to the second connection portion 13 as indicated by the arrow in FIG. 3). ), The normal operation unit 4 (first operation unit 4A) on which numeric keys for using the telephone function and the like are arranged is exposed below the first display unit 5A in the vertical screen direction.

  Further, when operating functions available on the second display unit 5B (when the horizontal screen function is used), as shown in FIG. 4, the first member 1 and the second member 2 are overlapped, as shown in FIG. When the second member 2 is activated and rotated with respect to the first member 1 via the hinge device portion H as shown by the middle arrow, the second display portion 5B on the lower side surface of the second member 2 and the first side surface on the upper side of the first member 1 are changed. The keyboard (second operation unit 4B) is disposed below the second display unit 5B with the second operation unit 4B exposed and in the horizontal screen direction. At this time, since the first operation unit 4A is also exposed, it is possible to assign an operation key for a horizontal screen function to the first operation unit 4A.

  As described above, this embodiment can be used by switching between two usage modes according to the function to be used.

  That is, for example, the first operation unit 4 such as a numeric key is exposed in the extension direction in the length direction of the substantially rectangular first display unit 5A, and the first operation unit 4A is below the vertically long first display unit 5A. Use mode (when using the vertical screen function) suitable for operations such as a telephone function where the user is positioned, and the second display unit 5B and the second operation unit 4B are exposed and below the horizontally long second display unit 5B. In addition, it is possible to easily design and realize a mobile phone that can be used by switching between the usage mode (when the horizontal screen function is used) suitable for operations such as keyboard typing where the second operation unit 4B is located.
