It has a base layer 12 on which the holes 22A are formed. The surface layer 11 and the base layer 12 have a rectangular shape when viewed from above, and have the same shape and size as each other.

The surface layer 11 is composed of a decorative material 20 which is located above and whose surface constitutes the upper surface of the top plate 2, and a sensor sheet 23 which is located below the decorative material 20. The decorative material 20 and the sensor sheet 23 have a rectangular shape when viewed from above, and have the same shape and size as each other.
The surface of the decorative material 20 facing upward is provided with a pattern having a design such as a wood grain. For the decorative material 20, for example, a melamine decorative material can be adopted. The layer structure of the surface layer 11 is not limited to this. For example, a core sheet made of kraft paper may be interposed between the decorative material 20 and the sensor sheet 23.

The sensor sheet 23 is made of, for example, a paper material. The shape and size of the sensor sheet 23 are the same as those of the decorative material 20. An adhesive (not shown) is interposed between the decorative material 20 and the sensor sheet 23. The decorative material 20 and the sensor sheet 23 are fixed by the adhesive.

The through hole 22A has a circular shape when viewed from above. The position, quantity, and shape of the through hole 22A can be arbitrarily changed.

As shown in FIG. 3, the sensor 9 (electrical component 90) includes an electrode 21 as a conductor 91, which is arranged on the back surface of the surface layer 11 and detects an operation on the top plate 2. Further, the sensor 9 is arranged in the through hole 22A and has an electrode connecting portion (conductor connecting portion) 30 electrically connected to the electrode 21.
The electrodes 21 are arranged on the back surface of the sensor sheet 23 on the surface layer 11, and the operation on the top plate 2 can be detected via the surface layer 11. In the present embodiment, the electrode 21 is formed by printing a conductive material such as nano-silver ink on the sensor sheet 23. The electrode 21 may be formed in a plate shape or a film shape, and may be attached to the sensor sheet 23 by adhesion or the like.

As shown in FIG. 2, the electrode 21 is arranged so that at least a part thereof faces the through hole 22A. The electrode 21 has a rectangular shape in which a pair of two sides extend in the front-rear direction X and the remaining pair of two sides extend in the left-right direction Y when viewed from above.

The spring member 34 is a leaf spring, and constitutes an urging portion 35 that urges the contact portion 33 toward the electrode. Further, the upper end of the spring member 34 constitutes a contact portion 33. Therefore, even if the dimensions between the sensor substrate 32 and the electrode 21 vary, the sensor substrate 32 and the electrode 21 can be reliably electrically connected. Further, the sensor board 32 is electrically connected to the control unit 15.

Next, the operation method of the desk device 1 according to the present embodiment will be described.
When the user raises or lowers the top plate 2 of the desk device 1, a predetermined operation is performed on the portion of the upper surface of the top plate 2 located above the electrodes 21. As a predetermined operation, for example, when a finger in contact with the upper surface of the top plate 2 is slid to one side of the left-right direction Y, the top plate 2 is moved up and down, and when it is slid to the other side, the top plate 2 is lowered. , Can be set arbitrarily.

When the sensor board 32 recognizes the operation content detected by the electrode 21 via the contact unit 33, the sensor board 32 transmits the operation content to the control unit 15. Then, the control unit 15 generates a command value to be input to the elevating drive unit 10, and then inputs the command value to the elevating drive unit 10. The elevating drive unit 10 drives the elevating drive unit 10 based on the input command value, so that the top plate 2 of the desk device 1 elevates or descends.

As described above, according to the desk device 1 according to the present embodiment, the electrical component 90 is arranged in the conductor 91 arranged on the back surface of the surface layer 11 and the through hole 22A formed in the base layer 12. A conductor connecting portion 30 is provided. Therefore, it is possible to make it difficult for the member for conducting the electrical component 90 to be visually recognized from the outside. As a result, the electrical component 90 can be used while improving the appearance as compared with the configuration in which the wiring or the like is arranged and connected to the outside.

Further, the electrode connecting portion 30 connected to the electrode 21 has an urging portion 35 for urging the contact portion 33 in contact with the electrode 21 toward the electrode 21. Therefore, it is possible to maintain the state in which the contact portion 33 is always in contact with the electrode 21, and the conductive state between the electrode 21 and the contact portion 33 can always be improved.

Further, since the sensor 9 for detecting the operation is arranged on the back surface of the surface layer 11, the electrode 21 can detect the operation performed by the user on the top plate 2.
Therefore, the user can perform a desired operation on the top plate 2 while using the top plate 2.
Further, although the spring member 34 is an urging portion 35 that urges the contact portion 33 toward the electrode, the upper end portion thereof serves as the contact portion 33, thereby reducing the number of parts and simplifying the electrode connecting portion 30. It can be configured as such.

Further, since the electrode 21 is arranged between the decorative material 20 and the base material 22, the distance between the electrode 21 and the finger of the user who operates on the top plate 2 can be shortened. Therefore, when the user's finger comes into contact with the electrode 21, the change in capacitance can be easily detected.
Further, since the electrode 21 is printed on the sensor sheet 23, the shape of the electrode 21 can be freely changed, and the shape of the electrode 21 can be freely changed. It becomes possible to produce, and the initial cost for manufacturing can be suppressed.

Further, a through hole 22A is formed in the base material 22, and at least a part of the electrode 21 is located at the same position as the through hole 22A in the top view. Therefore, it is possible to increase the size of the electrode 21 in the top view while reducing the size of the through hole 22A in which the electrode connecting portion 30 is arranged in the top view. As a result, the through hole 22A can be made smaller to secure the strength of the top plate 2, and the electrode 21 can be made larger to widen the range on the top plate 2 that the user can operate.
