FIG. 5 is a front view showing a slide mechanism of the electronic device according to the present embodiment. FIG. 6 is a front view showing the operation of the slide mechanism of the electronic device according to the present embodiment. In addition, in FIGS. 5 and 6, the portion that is actually overlapped and hidden is represented by a solid line for convenience.

The slide mechanism 4 moves the display panel 3 with respect to the front panel (panel: first member) 2F of the chassis 2, the chassis (second member) 5, the guide shaft 6, and the drive unit 7.
And an elastic member 8.

The chassis 5 is a plate-shaped member provided along the rear side of the display panel 3. The chassis 5 fixes the display panel 3 and slides the display panel 3 in the vertical direction by itself.

The guide shaft 6 is on the rear side of the chassis 5 and extends and is fixed along the vertical direction. The guide shaft 6 is formed in a cylindrical shape in the present embodiment. The guide shaft 6 may have a prismatic shape or an elliptical pillar shape. The upper and lower ends of the guide shaft 6 are fixed via the support pieces 5A that protrude from the upper and lower ends of the chassis 5 to the rear side, extend along the left-right direction, and face each other in the vertical direction.

The drive unit 7 has a drive mechanism 7A provided on the front panel 2F, a guide member 7B also provided on the front panel 2F, and a groove 7C provided on the chassis 5.

The drive mechanism 7A includes a motor 7Aa as a drive source, a cam 7Ab, a reduction gear 7Ac that transmits the rotational force of the motor 7Aa to the cam 7Ab, and a detection unit 7Ad that detects the rotational position of the cam 7Ab.

A worm gear 7Aa is fixed to the output shaft of the motor 7Aa. The worm gear 7Aaa meshes with the first gear of the reduction gear 7Ac.

The reduction gear 7Ac is a group of gears composed of a plurality of gears that mesh with each other. In the present embodiment, each of the reduction gears 7Ac is composed of spur gears. As described above, in the reduction gear 7Ac, the first gear of meshing meshes with the worm gear 7Aaa of the motor 7Aa. In the reduction gear 7Ac, the gear at the final stage of meshing meshes with the cam 7Ab.

The cam 7Ab has a driven gear 7Aba, a cam portion (rotating member) 7Abb, and a pin 7Abc. The driven gear 7Aba is composed of a spur gear and meshes with the final gear of the meshing of the reduction gear 7Ac. The cam portion 7Abb is fixed to the driven gear 7Aba. The pin 7Abc is fixed in the cam portion 7Abb at a position eccentric from the rotating shaft 7Abd at the center of rotation of the driven gear 7Aba. Therefore, in the cam 7Ab, the rotational force of the motor 7Aa is transmitted to the driven gear 7Aba via the reduction gear 7Ac, and the driven gear 7Aba rotates around the rotating shaft 7Abd. Then, in the cam 7Ab, the cam portion 7Abb rotates about the rotation shaft 7Abb with the rotation of the driven gear 7Aba, and the pin 7Abc fixed to the cam portion 7Abb is on the surface in the vertical and horizontal directions about the rotation shaft 7Abb. Turn around at.

The detection unit 7Ad has a detection gear 7Ada that meshes with the driven gear 7Aba and rotates together with the driven gear 7Aba separately from the reduction gear 7Ac, and a detection sensor 7Adb that detects the rotation of the rotating shaft fixed to the center of the detection gear 7Ada. .. Therefore, the detection unit 7Ad detects the rotation position of the rotation shaft of the detection gear 7Ada that rotates together with the driven gear 7Aba by the detection sensor 7Adb, thereby detecting the rotation position of the cam 7Ab and the turning position of the pin 7Abc.

In the drive mechanism 7A described above, the motor 7Aa, the reduction gear 7Ac, the driven gear 7Aba of the cam 7Ab, and the detection unit 7Ad are arranged on the rear side of the front panel 2F, and the cam part 7Abb and the pin 7Abc of the cam 7Ab are on the front side. Arranged on the front side of the panel 2F, the pin 7Abc is provided so as to extend to the front side of the front panel 2F.

A plurality of guide members 7B are provided vertically (two in the present embodiment) at the left and right ends on the front side of the front panel 2F, and are fixed to the front panel 2F. The guide member 7B inserts the guide shaft 6 and has an insertion hole. Therefore, the guide member 7B inserts and supports the guide shaft 6 so as to allow the guide shaft 6 to slide and move in the vertical direction.

The groove 7C is provided in the chassis 5. The groove 7C is formed of a synthetic resin material fixed to the chassis 5, and opens toward the rear side of the chassis 5 along the surfaces in the vertical and horizontal directions. The groove 7C is formed so as to extend along the left-right direction orthogonal to the front-rear direction which is the extending direction of the rotating shaft 7Abd in the cam 7Ab and the vertical direction which is the extending direction of the guide shaft 6 (the moving direction of the chassis 5). Has been done.

In this embodiment, the elastic member 8 is configured as a torsion spring. The elastic member 8 as a torsion spring has a torsion portion supported by the chassis 5, and each end thereof is hung on the chassis 5. One end of the elastic member 8 is provided so as to reach the inside of the groove 7C. The elastic member 8 may be elastic and may be provided inside the groove 7C.

Then, in the slide mechanism 4, the guide shaft 6 fixed to the chassis 5 is inserted and supported by the guide member 7B fixed to the front panel 2F, and the cam on the front panel 2F side is inserted into the groove 7C on the chassis 5 side. It is assembled by inserting the pin 7Abc of 7Ab.

In the slide mechanism 4, as shown in FIGS. 5 and 6, the motor 7Aa of the drive mechanism 7A is driven by the drive unit 7 on the front panel 2F, and the pin 7Abc of the cam 7Ab swivels. FIG. 5 shows the lowest position where the pin 7Abc, which has swiveled clockwise around the rotation shaft 7Abd from FIG. 6, has moved to the lowermost position, and FIG. 6 shows the rotation shaft from the lowest position in FIG. It shows the uppermost position where the pin 7Abc, which has swiveled counterclockwise around 7Abd, swivels 180 degrees and moves to the uppermost position. Then, in the slide mechanism 4, the pin 7Abc swivels along with the groove 7C. Here, the chassis 5 is provided with a guide shaft 6 extending in the vertical direction, and the guide shaft 6 is inserted and supported by a guide member 7B on the front panel 2F so as to be slidable in the vertical direction. Therefore, the chassis 5 is allowed only to slide in the vertical direction while being restricted from moving in the front-rear and left-right directions due to the relationship between the guide shaft 6 and the guide member 7B with respect to the front panel 2F. Further, the groove 7C of the chassis 5 is formed so as to extend in the left-right direction. Therefore, in the turning movement of the pin 7Abc, the movement in the left-right direction is canceled by the length in the left-right direction of the groove 7C, and only the movement in the up-down direction is given to the chassis 5 without being transmitted to the chassis 5. As a result, the slide mechanism 4 slides the chassis 5 in the vertical direction with respect to the front panel 2F. As a result, the slide mechanism 4 moves the display panel 3 downward to the reference position (first position) shown in FIG. 5 which is the moving end position, and the slide mechanism 4 moves the display panel 3 to the moving end position shown in FIG. It can be moved up to the second position).

Then, in the slide mechanism 4, when the pin 7Abc of the cam 7Ab reaches the lowest position as shown in FIG. 5, the elastic member 8 is pressed downward by the pin 7Abc. Therefore, in the slide mechanism 4, the elastic force of the elastic member 8 is generated between the pin 7Abc and the groove 7C and is applied to the chassis 5 through the groove 7C so as to press the chassis 5 downward. It works. The elastic force of the elastic member 8 has a smaller relationship than the rotational force (driving force) transmitted from the motor 7Aa of the drive mechanism 7A that swivels and moves the pin 7Abc to the driven gear 7Aba of the cam 7Ab via the reduction gear 7Ac.

Hereinafter, the fixed structure of the guide shaft 6 of the present embodiment will be described. 7 to 16 show a fixed structure of the guide shaft 6 according to the present embodiment.

The fixed piece 11B has a hook-shaped claw portion 11Ba formed at a base end portion extending from the fixed base portion 11A. The tip of the claw portion 11Ba is oriented in the direction opposite to the extending direction of the fixing piece 11B, and is formed in the circumferential direction of the fixing base portion 11A and in the axial direction of the guide shaft 6. Further, the fixing piece 11B has a through hole 11Bb formed through the plate shape at the tip portion extending from the fixing base portion 11A. The claw portion 11Ba of the fixing piece 11B engages with the engaging hole 5B provided in the chassis 5. The claw portion 11Ba and the engaging hole 5B that engage with each other form the engaging portion 13. Further, the through hole 11Bb of the fixing piece 11B is fixed to the chassis 5 via a screw 14a screwed into the screw hole 5C provided in the chassis 5. The through hole 11Bb, the screw hole 5C, and the screw 14a of the fixing piece 11B constitute the rotation prevention means 14.

As shown in FIG. 8, the mounting holes 12 are provided so as to penetrate through the support pieces 5A provided so as to face each other in the vertical direction in the chassis 5. The mounting holes 12 are formed as elongated holes extending in the left-right direction along the plate surface of the chassis 5. In the present embodiment, the mounting holes 12 are formed as elongated holes that face each other in the vertical direction. Further, the mounting holes 12, which are elongated holes facing each other in the vertical direction, extend in parallel with each other and are displaced in the left-right direction so that one end portion 12A thereof is located on the alternate long and short dash line L1 in FIG. 8 and faces each other. The end portion 12B is provided so as to extend in the opposite direction to the left and right. Further, as shown in FIG. 9, the mounting hole 12, which is a long hole, has a groove width (chassis) equivalent to the diameter of the protrusion 11Ab so that one end 12A fits the diameter D of the protrusion 11Ab of the fixing base 11A. 5 is formed in the width dimension W1 in the front-rear direction, and the other portion is formed in the groove width W2 larger than the diameter D of the one end portion 12A and the protrusion 11Ab.

The support member 15 is fixed to the chassis 5 as shown in FIG. The support member 15 is formed so that one side in the left-right direction is open. Then, the support member 15 supports the guide shaft 6 by inserting and fitting the guide shaft 6 in the middle from the open portion.

The procedure for fixing the guide shaft 6 to the chassis 5 by the fixing structure of the guide shaft 6 configured as described above will be described.

First, as shown in FIGS. 8 and 9, the protrusions 11Ab of the fixing base 11A of the fixing members 11 fixed to both ends of the guide shaft 6 are formed at the wide groove width W2 of each mounting hole 12 on the chassis 5 side. Insert it on the other end 12B side. Further, as shown in FIG. 8, the guide shaft 6 is inserted and fitted from the open portion of the support member 15. Then, the guide shaft 6 is supported by the support member 15 in a form inclined in the left-right direction with respect to the other end 12B of each mounting hole 12 displaced in the left-right direction. At this time, the fixing piece 11B in the fixing member 11 is arranged at a position away from the chassis 5.

Next, as shown in FIGS. 10 and 11, the guide shaft 6 is raised from a form tilted in the left-right direction along the vertical direction. Specifically, the protrusion 11Ab of each fixing base 11A in the fixing member 11 is slid in the length direction (left-right direction) of each mounting hole 12 toward one end 12A, which is a portion of the narrow groove width W1 of each mounting hole 12.

Then, the guide shaft 6 is completely fitted to the support member 15 in a form in which one end portion 12A of each mounting hole 12 is erected and arranged on the opposed alternate long and short dash line L1. Therefore, in the guide shaft 6, the protrusion 11Ab of the fixing base 11A in the fixing member 11 fits into the one end 12A of the narrow groove width W1 of each mounting hole 12, and the guide shaft 6 fits into the support member 15 in the middle of the extending direction. By doing so, the sliding movement of each mounting hole 12 to the wide other end 12B side is restricted.

Next, as shown in FIGS. 12 and 13, each fixing base 11A of the fixing member 11 is rotationally moved in the axial direction of the guide shaft 6. Specifically, the fixing member 11 is rotated in the axial direction of the guide shaft 6 with the claw portion 11Ba facing until the fixing piece 11B comes into contact with the plate surface of the chassis 5. Then, in the fixing member 11, the claw portion 11Ba of the fixing piece 11B is inserted into the engaging hole 5B of the chassis 5 and engages with the edge of the engaging hole 5B. Further, in the fixing member 11, the through hole 11Bb of the fixing piece 11B coincides with the screw hole 5C of the chassis 5.

Next, as shown in FIGS. 14 and 15, the screw 14a is screwed into the screw hole 5C of the chassis 5 through the through hole 11Bb of the fixing piece 11B to fix the fixing member 11 to the chassis 5. As a result, the fixing piece 11B is separated from the chassis 5, the claw portion 11Ba is removed from the locking hole 5B, and the fixing member 11 is prevented from rotating and moving in the axial direction of the guide shaft 6. Therefore, the guide shaft 6 is completely fixed to the chassis 5.

By the way, in the above-described embodiment, it has been described that the rotation prevention means 14 is composed of the through hole 11Bb, the screw hole 5C and the screw 14a of the fixing piece 11B described above, but the present invention is not limited to this. For example, as shown in FIG. 16, the engaging hole 11Bc forming a snap fit is formed in place of the through hole 11Bb of the fixing piece 11B, and the engaging hole 5D is formed in place of the screw hole 5C. When the engaging claw 11Bc engages with the edge of the 5D, the fixing piece 11B is similarly separated from the chassis 5, the claw portion 11Ba comes out of the locking hole 5B, and the fixing member 11 moves in the axial direction of the guide shaft 6. It can be prevented from rotating and moving.

Further, in the above-described embodiment, the elongated mounting holes 12 are displaced in the left-right direction, and one end portion 12A thereof is located on the alternate long and short dash line L1 in FIG. The configuration is such that it extends in the opposite direction to the left and right, but this is not the case. For example, although not clearly shown in the figure, each of the elongated mounting holes 12 does not shift in the left-right direction, and one end portion 12A thereof is located on the alternate long and short dash line L1 in FIG. 8 and faces each other while the other end. The portion 12B may be provided so as to extend in the same direction on the left and right. In this case, when the guide shaft 6 is fixed to the chassis 5, the guide shaft 6 is inserted into each mounting hole 12 so that the protrusions 11Ab of the fixing base 11A of the fixing members 11 fixed to both ends of the guide shaft 6 are inserted into the mounting holes 12. Tilt in the vertical direction. Then, with each protrusion 11Ab inserted into each mounting hole 12, each protrusion 11Ab is arranged on the other end 12B side, which is a portion of the wide groove width W2 of each mounting hole 12 on the chassis 5 side. After that, the guide shaft 6 is translated in the left-right direction, each protrusion 11Ab is fitted to one end 12A of each mounting hole 12, and the guide shaft 6 is fitted with the alternate long and short dash line L1 on which the one end 12A of each mounting hole 12 faces. It fits against the support member 15 in the form arranged above.

Further, in the above-described embodiment, the mounting holes 12 and the elongated holes are configured, but the present invention is not limited to this. For example, one mounting hole 12 is a long hole and the other mounting hole 12 is a round hole. The round hole mounting hole 12 has a diameter of W1 and a protrusion 11Ab fits into the mounting hole 12. In this case, when the guide shaft 6 is fixed to the chassis 5, one of the protrusions 11Ab is inserted into each mounting hole 12 so that the protrusion 11Ab of the fixing base 11A in the fixing member 11 fixed to both ends is inserted into each mounting hole 12. The guide shaft 6 is tilted in the vertical direction so as to be arranged on the other end 12B side, which is a portion of the wide groove width W2 of the mounting hole 12. Then, with each protrusion 11Ab inserted into each mounting hole 12, one protrusion 11Ab is slid along the elongated hole of one mounting hole 12, and one protrusion 11Ab is moved to one mounting hole 12. The guide shaft 6 is fitted to the support member 15 in a form in which the guide shaft 6 is arranged on the alternate long and short dash line L1 on which the one end 12A of each mounting hole 12 faces.

As described above, the fixing structure of the guide shaft 6 of the present embodiment is a structure for fixing the guide shaft 6 to the chassis 5, and includes a fixing member 11 attached to the end portion of the guide shaft 6, and the chassis 5 is a guide. It has a mounting hole 12 which is an elongated hole in which the fixing member 11 can be inserted along the axial direction of the shaft 6 and the fixing member 11 can be slidably moved along the intersecting direction of the guide shaft 6 in the axial direction. ..
