Electronic device and stand

1. An electronic device placed on a placement surface, the electronic device comprising:

a device body; and

a stand that is placed on the placement surface and supports the device body,

wherein the stand includes:

a base including a lower surface that faces the placement surface;

a suction member that is elastic, faces the lower surface of the base, includes a suction surface that adheres to the placement surface by negative pressure generated in a gap between the placement surface and the suction surface, and includes a ventilation hole that is in fluid communication with the gap; and

a slide valve that is located between the base and the suction member and slides between an opened position and a closed position along the lower surface of the base, the opened position being a position at which the ventilation hole is opened to let air into the gap, the closed position being a position at which the ventilation hole is closed to interrupt air into the gap, and

when the slide valve is in the closed position, the suction member generates the negative pressure in the gap by elastically deforming in a direction away from the placement surface when the stand is under an external force acting in the direction away from the placement surface.

2. The electronic device according to claim 1 ,

wherein the stand further includes a slip sheet located between the slide valve and the suction member, the slip sheet having a slippery property, and

the slide valve slides between the opened position and the closed position by sliding on the slip sheet.

3. The electronic device according to claim 1 ,

wherein the slide valve includes:

a valve body that slides between the opened position and the closed position along a depth direction of the electronic device; and

a knob used to slide the valve body, the knob being provided at an end portion of the valve body at a back side in the depth direction.

4. The electronic device according to claim 3 ,

wherein the base includes an insertion hole into which the knob is inserted in a manner that the knob is movable in the depth direction, the insertion hole being located at an end portion of the base at the back side in the depth direction.

5. The electronic device according to claim 3 ,

wherein an end portion of the valve body at a front side in the depth direction is located to be exposed to an end portion of the base at the front side in the depth direction when the valve body is in one of the opened position and the closed position.

6. The electronic device according to claim 3 ,

wherein the valve body includes an opening portion, and

the opening portion is in fluid communication with the ventilation hole when the valve body is in the opened position, and is not in fluid communication with the ventilation hole when the valve body is in the closed position.

7. The electronic device according to claim 6 ,

wherein a recessed portion is located in the lower surface of the base, the recessed portion serving as a channel through which air flows into the gap via the opening portion and the ventilation hole, when the valve body is in the opened position.

8. The electronic device according to claim 3 ,

wherein the stand further includes an engagement mechanism for providing tactile feedback when sliding the slide valve.

9. The electronic device according to claim 1 ,

wherein the electronic device is an image display device, and

the device body includes a display panel for image display.

10. A stand placed on a placement surface and supports a device body, the stand comprising:

a base including a lower surface that faces the placement surface;

a suction member that is elastic, faces the lower surface of the base, includes a suction surface that adheres to the placement surface by negative pressure generated in a gap between the placement surface and the suction surface, and includes a ventilation hole that is in fluid communication with the gap; and

a slide valve that is located between the base and the suction member and slides between an opened position and a closed position along the lower surface of the base, the opened position being a position at which the ventilation hole is opened to let air into the gap, the closed position being a position at which the ventilation hole is closed to interrupt air into the gap, and

when the slide valve in the closed position, the suction member generates the negative pressure in the gap by elastically deforming in a direction away from the placement surface when the stand is under an external force acting in the direction away from the placement surface.
