Next, if the second casing (2) is pressed backward in the tilted state shown in FIG. 27 (b) and the connecting arm (31) is slightly rotated clockwise, then the second casing FIG. 27 (c) shows that the connecting arm (31) is urged by the hinge unit (4) while the sliding surface (29) of (2) is in contact with the receiving surface (33) of the connecting arm (31). It rotates to the rotation angle of the rotation full open state, and is received by the 1st housing | casing (1) at this rotation angle.
As the connecting arm 31 is rotated, the second housing 2 is rotated rearward, and finally the first display surface 11 and the second display surface 21 are on the same plane. Will be aligned.

Further, when the second casing (2) is pulled toward the first casing (1) from the fully opened state shown in FIG. 27 (c), the slide surface (29) of the second casing (2) is connected. By sliding on the receiving surface (33) of the arm (31), the second housing (2) moves horizontally to the fully open position shown in FIG. 27 (d), and finally the first housing ( 1) abut.
As a result, as shown in FIG. 7, the first display surface (11) and the second display surface (21) come close to each other, and one large screen is formed by both the display surfaces (11) (21). Become.

  In the fully open state, as shown in FIG. 15 (b), the convex portion (10) of the first casing (1) and the concave portion (20) of the second casing (2) are engaged with each other so that both casings (1 ) (2) are linked. Therefore, even if the second display surface (21) is strongly touch-operated in this state, the second casing (2) maintains a constant posture with respect to the first casing (1).

FIGS. 17A, 17B and 17C show the bending deformation of the flexible lead 7 in the process from the fully closed state to the fully open state of the slide and then to the fully open state of the slide.
In the fully closed state shown in FIG. 17A, as described above, the sliding contact surface (311) formed on the second arm portion (36) of the connecting arm (31) and the second casing (2) are formed. The sliding contact surfaces (211) are in contact with each other, and the second housing (2) is prevented from sliding in the direction indicated by the two-dot chain line arrow.

Next, in the fully open state shown in FIG. 17 (b), the flexible lead (7) moves between the second lead portion (72) and the third lead portion (73) as the connecting arm (31) turns. It is bent and deformed greatly.
Then, from the state shown in FIG. 17 (b), the second casing (2) is slid forward (to the left in the figure) by a distance T as shown by the arrow in FIG. 17 (c). The slide is fully opened. In this process, the flexible lead (7) is displaced forward at a bending portion between the second lead portion (72) and the third lead portion (73) with a larger curvature.

  In the portable electronic device, since the second housing (2) is prevented from moving in the direction indicated by the chain line arrow in the fully closed state shown in FIG. When the second housing (2) slides by the operation of (8), the length of the flexible lead (7) can be shortened by a margin length to be given to the flexible lead (7).

  Therefore, the flexible lead (7) can be formed in a length considering only the bending deformation of the flexible lead (7) accompanying the rotation of the connecting arm (31) shown in FIGS. . As a result, the slack of the flexible lead (7) in the fully closed state shown in FIG.

  In the portable electronic device, as shown in FIG. 23, the engaging piece (216) is integrally projected from the synthetic resin front cabinet (2a), and is engaged with the stainless steel holder member (221). Since the receiving piece (222) is integrally projected, the synthetic resin engaging piece (216) and the stainless steel engaging receiving piece (222) are engaged with each other.

  The hook structure comprising the synthetic resin engaging piece and the stainless steel engaging receiving piece is also used for locking the first display (12) in the first housing (1). (Not shown).

Therefore, compared to the conventional configuration in which the engagement piece and the engagement receiving piece made of synthetic resin are engaged with each other, the plate accompanying the change of the engagement receiving piece from the synthetic resin to the stainless steel The gap between the first display (12) and the second display (22) in the fully opened state is reduced by the thickness reduction (about 1.0 mm on both the first housing side and the second housing side in the above example). Get smaller.
As a result, as shown in FIG. 7, a large image is displayed with both display surfaces (11) and (21) as one screen in a state where the two display surfaces (11) and (21) are aligned on the same plane (slide fully open state). In this case, a good image display with a slight discontinuity is realized.

In the portable electronic device, the first casing (1) and the second casing (2) are connected to each other by applying a turning force toward the tilt state to the second casing (2) in the fully open slide state. It is possible to shift directly from the slide fully open state to the tilted state without going through the rotational fully open state.
28 and 29 show the sliding contact surface of the connecting arm (31) with respect to the sliding contact surface (211) of the second casing (2) in the process from the fully open state to the fully closed state through the tilt state. The manner in which (311) slides is shown with reference to the second housing (2).

  In the fully open state, the sliding contact surface (311) of the connecting arm (31) and the sliding contact receiving surface (211) of the second housing (2) are separated from each other as shown in FIG. When the connecting arm (31) rotates from the state as shown by an arrow, the sliding contact of the connecting arm (31) on the sliding contact surface (211) of the second housing (2) as shown in FIG. 28 (b). The surface (311) is in sliding contact.

  Thereafter, the connecting arm (31) is rotated to the fully closed state shown in FIG. 29 (d), so that the second casing is shown in FIGS. 28 (b) (c) and 29 (a)-(d). The sliding contact surface (311) of the connecting arm (31) slides against the sliding contact receiving surface (211) of (2), and the second housing of the connecting arm (31) is caused by the cam action accompanying this sliding. The pivot shaft (hinge member (5) (51)) on the (2) side moves relative to the second housing (2) in the sliding direction of the slide mechanism (left direction in the figure).

  Then, in the fully closed state shown in FIG. 29 (d), the connecting arm remains in contact with the sliding contact surface (211) of the second housing (2) while the sliding contact surface (311) of the connecting arm (31) is in sliding contact. The pivot (hinge member (5) (51)) on the second housing (2) side of (31) reaches the slide moving end.

  In the process from the fully open state to the fully closed state through the tilt state as described above, the sliding contact surface (311) of the connecting arm (31) is in contact with the sliding contact receiving surface (211) of the second housing (2). By sliding, the second housing (2) moves relative to the connecting member (32) in the sliding direction of the sliding mechanism (right direction in the figure), and the results are shown in FIGS. 29 (c) to 29 (d). In the final stage shown, as shown in FIGS. 30 and 31, the convex portion (218) of the second housing (2) is fitted into the through hole (312) of the connecting member (32), and the second housing ( The convex portion (218) of 2) and the through hole (312) of the connecting member (32) are engaged with each other.

  In a state where the convex portion (218) of the second casing (2) and the through hole (312) of the connecting member (32) are engaged with each other, the sliding contact surface (311) of the connecting arm (31) and the second casing The sliding contact surface (211) of the body (2) is maintained in sliding contact with each other, or the sliding contact surface (311) of the connecting arm (31) is connected to the sliding contact surface (2) of the second housing (2). 211).

Therefore, in the fully closed state, as shown in FIG. 29 (d), the sliding contact receiving surface (211) of the second housing (2) is in contact with or faces the sliding contact surface (311) of the connecting arm (31). This prevents the second casing (2) from moving forward (to the left in the figure) and the outer peripheral surface on the rear side of the convex portion (218) of the second casing (2) as shown in FIG. Makes contact with the inner peripheral surface of the connecting member (32) on the rear side of the through hole (312), thereby preventing the second housing (2) from moving rearward (rightward in the figure).
In this way, the position of the second casing (2) relative to the first casing (1) in the fully closed state is defined within a certain position or within a certain range, and the position of the second casing (2) is determined. Will do.

  As described above, according to the portable electronic device, turning force toward the tilt state is applied to the second housing (2) in the fully open slide state, so that the second housing (2) is rotated from the fully open state. Even if an operation of shifting to the fully closed state without performing the dynamic fully open state is performed, in the fully closed state, the second housing (2) is displaced to a predetermined position with respect to the first housing (1). The convex portion (218) of the second housing (2) can be engaged with the through hole (312) of the connecting member (32).

  In the above-described example, the second housing (2) is provided with the convex portion (218), and the connecting member (32) is provided with the through hole (312). However, the present invention is not limited to this. For example, you may provide a recessed part in a 2nd housing | casing (2), and a convex part in a connection member (32). Moreover, it is not limited to a recessed part and a convex part, What is necessary is just the latching structure which can prevent the slide of a 2nd housing | casing in a fully closed state.

Further, in the portable electronic device, when placed on a desk in a tilted state as shown in FIG. 32 (a), or placed on a desk in a fully open state as shown in FIG. 32 (b), the connecting arm (31) The corner portion protrudes from the back surface of the first housing (1), and the front end portion of the first housing (1) and the corner portion of the connecting arm (31) are grounded.
Here, in any state, the first casing (1) and the second casing (2) are arranged so that the center of gravity G is closer to the first casing (1) than the ground point of the connecting arm (31) as shown in the figure. ) And the L-shape of the connecting arm (31) are designed to stabilize the postures of the housings (1) and (2).

  Therefore, when placed on a desk in a tilted state as shown in FIG. 32 (a), for example, the touch panel of the front first casing (1) is operated while viewing the display of the rear second casing (2). I can do it.

  Also, when placed on a desk with the slide fully open as shown in FIG. 32 (b), both display surfaces (11) and (21) are slightly on the user side according to the amount of protrusion of the corner of the connecting arm (31). For example, an image can be viewed on a large screen by forming a single screen with both display surfaces (11) and (21). In this case, since both display surfaces (11) and (21) are sufficiently close to each other, it is possible to display an almost uninterrupted image on both display surfaces (11) and (21).

  Furthermore, in the portable electronic device, when the device is dropped on the floor surface, if the front end surface of the second housing (2) is in a downward posture so as to face downward, the portable electronic device is formed on the front end surface. Of the pair of convex portions (200) and (200), one of the convex portions (200) first collides with the floor surface, and immediately after that, the other convex portion (200) collides with the floor surface. Become.

  Here, as shown in FIG. 20, the second display (22) is arranged as close as possible to the front end surface of the second housing (2), and covers the second display (22). Since the glass plate (24) is provided, the distance between the front end surface of the glass plate (24) and the front end surface of the second housing (2) is very small. When an impact force acts on the front end surface of (2), the impact force is transmitted to the glass plate (24), and the glass plate (24) may be damaged.

However, in the portable electronic device, the pair of protrusions (200) and (200) are in a position shifted in the thickness direction from the glass plate (24) of the second housing (2), and the first 2 Display (22) is located at a position shifted in the width direction, and the convex part (200) exhibits a buffering action according to its height, so the front part where the convex part (200) is not formed. Compared with the case of colliding with the floor surface at the end face, the impact force acting on the glass plate (24) covering the second display (22) and the second display (22) is greatly relieved.
As a result, breakage of the glass plate (24) and the second display (22) due to the action of impact force is reduced.

  In addition, although the impact force by dropping may act on the glass plate (16) of the first casing (1) in the same manner, the rear end face of the first casing (1) in the fully closed state is shown in FIG. Since it is covered with the connecting member (32) shown in 9, the impact force to the glass plate (16) of the first housing (1) can be reduced.
