As described above, a slide mechanism for sliding a moving body by rotating a rotating member of an eccentric cam is generally known. However, when such a slide mechanism is applied to an electronic device, particularly a drive device that slides and moves a display panel as a moving body, there are the following problems.

When the moving body is a display panel, the display panel has a display, an operation unit, and a circuit board for driving them, which increases the weight. When such a heavy object is slid and moved by the rotation of the rotating member, the rotating member rotates when an external force such as gravity, vibration or impact is applied to the moving body, and the moving body is stable at the moved position. There is a risk that it will not be able to be held.

An object of the present invention is to provide a slide mechanism, a display panel driving device, and an electronic device capable of stably holding a moving body at a moving end position.

In order to achieve the above object, the slide mechanism of one aspect of the present invention includes a first member and a second member provided so as to be slidably movable in the first position and the second position with respect to the first member. A rotating member having a pin rotatably provided on the first member via a rotating shaft and rotating around the rotating shaft, a driving unit for rotating the rotating member, and the second member. The rotating member is provided with a groove in which the pin of the rotating member is engaged, and the rotating member is provided with the rotating shaft and the pin at the first position and the second position of the second member. Are arranged side by side in a straight line in the moving direction of the second member.

In order to achieve the above object, the display panel driving device of one aspect of the present invention includes the above slide mechanism and the display panel provided on the second member.

In order to achieve the above object, the electronic device of one aspect of the present invention includes the above display panel driving device.

In the slide mechanism, display panel drive device, and electronic device of the present invention, when the rotation shaft of the rotating member and the pin are arranged in a straight line in the moving direction of the second member, the load of the second member related to the pin is applied. Since the rotating shaft and the pin act on a straight line aligned with each other, the structure can be made strong against an external force in which the pin of the rotating member rotates around the rotating shaft.

The display panel 3 is installed on the front side of the housing 2. The display panel 3 has, for example, a display 3A including a liquid crystal display (LCD) or an organic EL (Organic Electro-Luminescence) display on the front surface. Further, the display panel 3 has an operation button 3B for performing various operations of the electronic device 1.

The display panel 3 is in an upright posture in the vertical direction, and is usually at a reference position (first position) so as to cover the front side of the front panel 2F provided on the front side of the housing 2 as shown in FIG. Be placed. Further, the display panel 3 slides upward in an upright posture so that the card slot 2Ga and the disk slot 2Gb on the front panel 2F appear as shown in FIG. 2 based on the operation of the operator (second operation position). Position). In this way, the display panel 3 is provided so as to be slidable between the reference position and the operating position. The slide movement of the display panel 3 is performed by the slide mechanism 4.

FIG. 3 is an exploded perspective view showing a slide mechanism of the electronic device according to the present embodiment. FIG. 4 is an exploded perspective view showing a slide mechanism of the electronic device according to the present embodiment. 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 to 9, 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 housing 2, and drives the chassis (second member) 5, which is a moving body, and the guide shaft 6. It has a portion 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. That is, the slide mechanism 4 constitutes a display panel driving device that slides and moves the display panel 3.

The guide shaft 6 extends and is fixed along the vertical direction at the left and right ends on the rear side of the chassis 5. 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 is 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 (rotary sensor) that detects the rotation of the rotating shaft fixed to the center of the detection gear 7Ada. It has 7Adb. 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 (moving direction of the chassis 5). Has been done. In the groove 7C, the upper wall surface 7Ca extends linearly in the left-right direction. Further, the groove 7C includes a narrow groove portion 7Cc in which the lower wall surface 7Cb facing the upper wall surface 7Ca downward is formed so as to have a narrow space between the upper wall surface 7Ca and the wide groove portion 7Cd in which the space between the upper wall surface 7Ca is wide. The middle part is formed so as to be inclined with respect to the left-right direction.

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 on the surface in the vertical and horizontal directions while being restricted from moving in the front-rear and left-right directions by the relationship between the guide shaft 6 and the guide member 7B with respect to the front panel 2F. There is. 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. That is, the groove 7C is provided so as to extend along the direction orthogonal to the slide movement direction on the surface formed by the slide movement of the chassis 5, and is set to a linear distance L1 from the pin 7Abc with reference to the center of the rotation axis 7Abd. On the other hand, it has a linear distance L2 longer than that and extends along the left-right direction. 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). Further, the slide mechanism 4 can stop the moving position of the chassis 5 at an arbitrary position by detecting the turning position of the pin 7Abc by the detection unit 7Ad. Further, in the cam 7Ab, the slide mechanism 4 has a chassis 5 by changing the distance between the rotating shaft 7Abd and the pin 7Abc because twice the distance between the rotating shaft 7Abd and the pin 7Abc is the sliding movement distance of the chassis 5. The distance of slide movement of 5 can be set.

In this slide mechanism 4, when the chassis 5 moves to the reference position shown in FIG. 5 and when the chassis 5 moves to the operating position shown in FIG. 6, the rotating shaft 7Abd and the pin 7Abc of the cam portion 7Abb of the chassis 5 They are arranged in a straight line in the vertical direction, which is the moving direction. The fact that the rotating shaft 7Abd and the pin 7Abc are aligned in a straight line means that the outer shape of the rotating shaft 7Abd and the outer shape of the pin 7Abc overlap each other when viewed from the vertical direction. In a more preferable form in which the rotating shaft 7Abd and the pin 7Abc are aligned in a straight line, the center of the rotating shaft 7Abd and the center of the pin 7Abc are arranged in a straight line in the vertical direction. That is, when the rotating shaft 7Abd and the pin 7Abc of the cam portion 7Abb are arranged side by side in a straight line in the moving direction of the chassis 5, the load of the chassis 5 related to the pin 7Abc is on the straight line where the rotating shaft 7Abd and the pin 7Abc are lined up. Therefore, it is possible to suppress the generation of an external force in which the pin 7Abc of the cam 7Ab turns around the rotation shaft 7Abd. Therefore, the generation of an external force for moving the chassis 5 is suppressed. As a result, the slide mechanism 4 can stably hold the chassis 5 at each moving end 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. As a result, the slide mechanism 4 can hold the chassis 5 at the reference position. 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. Although not explicitly shown in the drawing, the elastic member 8 may be provided so as to be pressed upward by the pin 7Abc when the pin 7Abc of the cam 7Ab reaches the uppermost position as shown in FIG. In this case, 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 to push the chassis 5 upward. To do. As a result, the slide mechanism 4 can hold the chassis 5 in the operating position.

7 to 9 are front views showing another example of the slide mechanism of the electronic device according to the present embodiment.

In another example of the slide mechanism 4 shown in FIGS. 7 and 8, the groove 7C is provided so as to extend in a direction inclined with respect to the direction orthogonal to the slide movement direction on the surface in the vertical and horizontal directions formed by the slide movement of the chassis 5. Has been done. The vertical and horizontal planes formed by the sliding movement of the chassis 5 indicate the plane (paper surface) formed by the Z-axis and the Y-axis in FIGS. 7 and 8, and the groove 7C slides and moves on the vertical and horizontal planes. It extends at an angle with respect to the Y-axis, which is the direction orthogonal to the direction.

In the slide mechanism 4 shown in FIG. 7, the groove 7C extends downward with respect to the Y axis from the position where the chassis 5 is engaged with the pin 7Abc when the chassis 5 is in the reference position. In such a configuration, when the chassis 5 is moved from the reference position to the operating position, the pin 7Abc starts to rotate counterclockwise in the opposite direction of the arrow α around the rotation shaft 7Abd, and the pin 7Abc interacts with the inclination in this initial movement. In addition, the surface pressure in contact with the upper wall surface 7Ca of the groove 7C becomes high. As a result, the slide mechanism 4 can smoothly perform the slide movement by increasing the driving force generated in the initial movement of moving the chassis 5 from the reference position to the operating position. Further, in the slide mechanism 4 shown in FIG. 7, when the chassis 5 is moved from the reference position to the operating position, the pin 7Abc turns counterclockwise in the opposite direction of the arrow α around the rotation shaft 7Abd, and the final movement is completed. The pin 7Abc interacts with the inclination to increase the surface pressure in contact with the upper wall surface 7Ca of the groove 7C. As a result, the slide mechanism 4 can hold the chassis 5 at the operating position by increasing the driving force generated at the final movement of moving the chassis 5 from the reference position to the operating position.

On the other hand, in the slide mechanism 4 shown in FIG. 8, the groove 7C extends upward with respect to the Y axis from the position where the chassis 5 engages with the pin 7Abc when the chassis 5 is in the reference position. In such a configuration, when the chassis 5 is moved from the operating position to the reference position, the pin 7Abc finishes turning clockwise around the rotation shaft 7Abd in the opposite direction of the arrow β, and in this final movement, the pin 7Abc tilts and moves with each other. The surface pressure that interacts with each other and comes into contact with the lower wall surface 7Cb of the groove 7C increases. As a result, the slide mechanism 4 can hold the chassis 5 at the reference position by increasing the driving force generated at the final movement of moving the chassis 5 from the operating position to the reference position. Further, when the above-mentioned elastic member 8 is present, the slide mechanism 4 can increase the elastic force of the elastic member 8 to hold the chassis 5 at the reference position. Further, in the slide mechanism 4 shown in FIG. 8, when the chassis 5 is moved from the operating position to the reference position, the pin 7Abc turns clockwise around the rotation shaft 7Abd in the opposite direction of the arrow β, and the pin is moved in the initial movement. The 7Abc interacts with the inclination to increase the surface pressure in contact with the lower wall surface 7Cb of the groove 7C. As a result, the slide mechanism 4 can smoothly perform the slide movement by increasing the driving force generated in the initial movement of moving the chassis 5 from the operating position to the reference position.

In the slide mechanism 4 shown in FIG. 9, a flat surface 7Abc1 is formed on a part of the peripheral surface of the pin 7Abc. The groove 7C with which the pin 7Abc engages is formed so that the upper wall surface 7Ca abuts on the flat surface 7Abc1 at the operating position where the chassis 5 is raised. That is, when the chassis 5 moves to the operating position, the upper wall surface 7Ca of the groove 7C comes into contact with the flat surface 7Abc1 of the pin 7Abc on the surface, thereby restricting the movement of the chassis 5 to the reference position side on each other surface. .. As a result, the slide mechanism 4 can hold the chassis 5 in the operating position.

The groove 7C with which the pin 7Abc is engaged may be formed so that the lower wall surface 7Cb abuts on the flat surface 7Abc1 at the reference position where the chassis 5 is lowered. In this case, the slide mechanism 4 can hold the chassis 5 at the reference position. In the present embodiment, the pin 7Abc comes into contact with the elastic member 8 at the reference position, but by pressing the elastic member 8 with the flat surface 7Abc1 of the pin 7Abc, the elastic force generated between the pin 7Abc and the elastic member 8 is pinned. It can be stably received on the flat surface 7Abc1 of 7Abc.

In the above-described embodiment, the configuration in which the chassis 5 is slid to the reference position (first position) and the operating position (second position) in the vertical direction has been described, but the present invention is not limited to this. For example, it is possible to slide and move to the reference position (first position) and the operating position (second position) in the composite direction including at least two in the left-right direction, the front-back direction, and the up-down front-back left-right direction.

In the above-described embodiment, the guide shaft 6 supports the chassis 5 so as to be slidable, but the present invention is not limited to this. For example, a rail may be used instead of the guide shaft 6.

As described above, the slide mechanism 4 of the present embodiment can slide and move to the front panel 2F as the first member and the reference position (first position) and the operating position (second position) with respect to the front panel 2F. It is a rotating member having a chassis 5 as a second member which is a moving body provided in the above, and a pin 7Abc which is rotatably provided on the front panel 2F via a rotating shaft 7Abd and swivels around the rotating shaft 7Abd. It has a cam portion 7Abb, a drive portion 7 for rotating and moving the cam portion 7Abb, and a groove 7C provided on the chassis 5 to which the pin 7Abc of the cam portion 7Abb engages. Then, in the slide mechanism 4 of the present embodiment, in the cam portion 7Abb, the rotating shaft 7Abd and the pin 7Abc are arranged linearly side by side in the moving direction of the chassis 5 at the reference position and the operating position of the chassis 5.

Therefore, according to the slide mechanism 4, when the rotating shaft 7Abd and the pin 7Abc of the cam portion 7Abb are arranged in a straight line in the moving direction of the chassis 5, the load of the chassis 5 related to the pin 7Abc is applied to the rotating shaft 7Abb. Since it acts on a straight line in which the pin 7Abc and the pin 7Abc are aligned, the structure can be made strong against an external force in which the pin 7Abc of the cam 7Ab turns around the rotation shaft 7Abd. As a result, the slide mechanism 4 can stably hold the chassis 5 at each moving end position. Further, since the slide mechanism 4 can hold the chassis 5 at the position where the rotation shaft 7Abd and the pin 7Abc of the cam portion 7Abb that slides the chassis 5 move, it is not necessary to separately provide a lock mechanism, and the number of parts can be reduced. It is possible to secure quality such as reduction of parts cost and assembly man-hours and improvement of assembly accuracy.

Further, the slide mechanism 4 of the present embodiment includes an elastic member 8 that generates an elastic force between the pin 7Abc and the groove 7C at least at a reference position of the chassis 5.

Therefore, according to the slide mechanism 4, the chassis 5 can be stably held at least at the reference position by the elastic force of the elastic member 8.

Further, in the slide mechanism 4 of the present embodiment, the reference position is the downward moving end position, and the operating position is the upward moving end position.

Therefore, according to this slide mechanism 4, it can be applied when the chassis 5 is slid and moved in the vertical direction, and the chassis 5 can be stably held at each moving end position in the vertical direction.

Further, in the slide mechanism 4 of the present embodiment, the groove 7C is provided so as to extend in a direction inclined with respect to the direction orthogonal to the slide movement direction on the surface formed by the slide movement of the chassis 5.

Therefore, according to the slide mechanism 4, the driving force generated in the initial movement and the final movement for moving the chassis 5 to the reference position or the operating position can be increased, and the slide movement can be smoothly performed.

Further, in the slide mechanism 4 of the present embodiment, the pin 7Abc has a flat surface 7Abc1 on a part of the peripheral surface, and the groove 7C is an upper wall surface that abuts on the flat surface 7Abc1 of the pin 7Abc at at least the operating position of the chassis 5. It has 7Ca (or lower wall surface 7Cb).

Therefore, according to the slide mechanism 4, the chassis 5 can be held in the operating position by the surface contact between the flat surface 7Abc1 and the upper wall surface 7Ca (or the lower wall surface 7Cb) of the groove 7C.
