The engagement lever 53 is rotatable about a support shaft 54 and has an engagement groove 55 on the opposite side of the operation lever 51 across the support shaft 54. The engaging pin 32 of the cam member 31 in a state where the major axis direction is the vertical direction can be engaged with the engaging groove 55.
A reversing spring 57 is installed between the protrusion 56 provided on the engagement lever 53 and the case 1. In addition, stopper pins 15 and 16 located on both sides of the protruding portion 56 are provided in the case 1.

Next, the operation of the slide device of the display panel 2 having the above configuration will be described.
1 and 3, the cam member 3 is laid sideways with the major axis direction as the horizontal direction, and the display panel 2 is in contact with the upper surface thereof. At this time, the engaging lever 53 is biased counterclockwise by the reversing spring 57 around the support shaft 54, and the protruding portion 56 is pressed against the stopper pin 16.
When the panel switch 21 on the upper surface of the display panel 2 is pressed, the cam member 3 rotates counterclockwise in the drawing via the drive gear 41, the intermediate gear 42, the driven gear 43 and the rotating shaft 31 by driving the motor 4. The rotation of the cam member 3 causes the display panel 2 in contact with the upper surface thereof to be lifted against the urging force of the tension spring 12, and to project upward along the guide 11, as shown in FIGS. As shown, the display panel 2 is in a protruding state (open state).

At this time, as shown in the figure, the detection switch 14 is turned on by the detection convex portion 34 and the driving of the motor 4 is stopped, and at the same time, the engagement pin 32 of the cam member 3 enters the engagement groove 55 of the engagement lever 53. It enters the state.
That is, when the cam member 3 rotates counterclockwise in the figure, the engagement pin 53 enters the engagement groove 55 and the engagement lever 53 rotates around the support shaft 54 in the clockwise direction in the figure. At the same time as being pressed against the stopper pin 15 by the urging of the reversing spring 57, the operating lever 51 connected to the engaging lever 53 via the connecting pin 52 slides upward, and its upper end is located above the case 1. Protruding.
In the protruding state of the display panel 2 described above, the cam member 3 is raised vertically with the major axis direction as the vertical direction, and the pressure angle of the cam member 3 becomes zero. Therefore, the display panel 2 is stably held against the action of external force and vibration.

When the panel switch 21 on the upper surface of the display panel 2 is pushed in such a state, the cam member 3 is rotated clockwise as shown in the figure through the drive gear 41, the intermediate gear 42, the driven gear 43 and the rotating shaft 31 by the reverse drive of the motor 4. At the same time, the display panel 2 in contact with the upper surface of the display panel 2 is housed downward along the guide 11 by the bias of the tension spring 12.
And as shown in FIG.1 and FIG.3, the display panel 2 will be in the accommodation state.
At this time, as shown in the figure, the detection switch 13 is turned on by the detection convex portion 33, and the drive of the motor 4 is stopped.
In the storage state of the display panel 2 described above, the cam member 3 is laid sideways with the major axis direction as the horizontal direction, and the pressure angle of the cam member 3 becomes zero. Therefore, the display panel 2 is stably held against the action of external force and vibration.

Further, when the operation lever 51 is pushed in the protruding state of the display panel 2, the engaging lever 53 rotates about the support shaft 54 counterclockwise via the connecting pin 52 at the lower end thereof, and the engaging groove 55. The engaging pin 32 inside is lifted. As a result, the cam member 3 is slightly rotated around the rotation shaft 31 in the clockwise direction in the figure.
At the same time as the engagement pin 32 is disengaged from the engagement groove 55, as shown in FIGS. 1 and 3, the engagement lever 53 is pressed against the stopper pin 16 by the biasing force of the reversing spring 57. It becomes a state.
Accordingly, when the upper surface of the display panel 2 is pressed, the cam member 3 that contacts the lower surface further rotates clockwise in the figure, and the cam member 3 has the major axis direction as the horizontal direction as shown in FIGS. In other words, the display panel 2 is stored.

Next, the pressure angle of the cam member 3 will be described.
FIG. 5 is an operation explanatory view showing the pressure angle of the cam member 3 and shows the case where the pressure angle θ> 0. At this time, the external force F at the point P causes the rotational force TF to act on the cam member 3 around the center Oc of the rotation shaft 31, so that the display panel 2 can be lowered.
That is, when the operation lever 51 is lowered by the external force f, the engagement lever 53 is rotated by the rotational force Tf around the center Or of the support shaft 54, the engagement pin 32 in the engagement groove 55 is lifted, and the cam member 3 is rotated. Slightly rotates clockwise around the center Oc, resulting in a pressure angle θ> 0. Accordingly, the display panel 2 can be lowered.

FIG. 6 is a view showing a state where the pressure angle of the cam member 3 is 0 when the display panel 2 is in an open state (a protruding state). At this time, in the cam member 3 in a state in which the major axis direction is vertically raised, the pressure angle at the contact point P with the display panel 2 becomes zero, and no rotational force is generated in the cam member 3 even by the action of the external force F.
In the figure, S2 indicates a range of a single R2 as a radius R2 from the center Oc to the point P.
Thus, in the open state of the display panel 2, the display panel 2 cannot be lowered even by external force or vibration and is stably held in a fixed state.

FIG. 7 is a view showing a state where the pressure angle of the cam member 3 is 0 when the display panel 2 is in the closed state (stored state). Also at this time, in the cam member 3 in the state where the major axis direction is set to the horizontal direction, the pressure angle at the contact point P with the display panel 2 is 0, and a rotational force is generated in the cam member 3 even by the action of the external force F. Absent.
In the figure, S1 indicates a range of a single R1 as a radius R1 from the center Oc to the point P.
Thus, even in the closed state of the display panel 2, the display panel 2 is stably held in a fixed state.

  As described above, by causing the cam member 3 to generate the pressure angle θ with a small external force f, the display panel 2 can be lowered by manual operation.

8 and 9 show the second embodiment. In the figure, 1 is a case (device main body), 2 is a display panel (sliding member), 6 is a cam member, 7 is a motor (driving means), and 8 is An operation lever (operation means).
In the second embodiment, the case (device main body) 1, the guide 11, the tension spring 12, the display panel (slide member) 2, the panel switch 21 and the like are the same as those in the first embodiment described above, and the guide 11 on the right side in the figure. Detection switches 17 and 18 are provided above and below.

The cam member 6 has a semicircular arm shape that comes into contact with the lower surface of the display panel 2 and has a semicircular portion and a rotating shaft 61 on the other end side. The cam member 6 forms a part of a link mechanism that is driven by a motor 7 that constitutes a driving means.
That is, the motor 7 includes a drive gear 71 on the motor shaft. A driven gear 73 is engaged with the drive gear 71 via an intermediate gear 72, and the driven gear 73 is integrally provided with an arm 74.

When the panel switch 21 on the upper surface of the display panel 2 is pressed, the driven gear 73 and the arm 74 are rotated counterclockwise as shown in FIG. The cam member 6 rotates in the clockwise direction in the drawing via the rotation shaft 61. The rotation of the cam member 6 causes the display panel 2 in contact with the semicircular portion to be lifted against the urging force of the tension spring 12, and to project upward along the guide 11, as shown in FIG. Thus, the display panel 2 is in a protruding state (open state).

At this time, as shown in the drawing, the detection switch 17 on the upper part of the guide 11 is turned off by passing above the lower end of the display panel 2, and the drive of the motor 7 is stopped.
In the protruding state of the display panel 2, the cam member 6 is aligned vertically with the arm 74, and the pressure angle θ of the cam member 6 becomes zero. Therefore, the display panel 2 is stably held against the action of external force and vibration.

When the panel switch 21 on the upper surface of the display panel 2 is pushed in such a protruding state, the driven gear 73 and the arm 74 are rotated clockwise through the driving gear 71 and the intermediate gear 72 by the reverse drive of the motor 7 and tilted. On the other hand, at the upper end of the arm 74, the cam member 6 rotates counterclockwise via the rotation shaft 61 and tilts at the same time, and at the same time, the display panel 2 in contact with the upper surface thereof is guided by the tension spring 12 to guide 11 The storage operation is performed downward.
And as shown in FIG. 8, the display panel 2 will be in the accommodation state.
At this time, as shown in the drawing, the detection switch 18 below the guide 11 is turned on by the lower end of the display panel 2, and the drive of the motor 7 is stopped.

When the operation lever 8 is pushed while the display panel 2 is protruding, the lower end pushes the lower end of the cam member 6 from the side. As a result, the cam member 6 is slightly rotated counterclockwise in the figure around the rotation shaft 61 and slightly tilted, and at the same time, the driven gear 73 and the arm 74 are slightly rotated clockwise in the figure and slightly tilted.
Accordingly, when the upper surface of the display panel 2 is pressed, the cam member 6 whose semicircular portion is in contact with the lower surface thereof is slightly rotated counterclockwise as shown in FIG. 2, and as shown in FIG. In this state, the display panels 2 are in a retracted state.

  As described above, in the projecting state of the display panel 2, the effect of the pressure angle θ = 0 of the cam member 6 can be obtained by arranging the arm-shaped cam member 6 and the arm 74 that constitute the link mechanism vertically. By pushing 8, the pressure angle θ ≠ 0 of the cam member 6 is set, and the storage operation by manual operation of the display panel 2 becomes possible.
