Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings.

However, the components described in the following embodiments are merely examples, and the scope of the present invention is not limited to them.

[Embodiment]
FIG. 1 schematically shows the appearance of the command input device of this embodiment.

As shown in FIG. 1, the command input device 1 is provided with a panel unit 3 having a pressing unit 2 when a user inputs a command to the command input device 1. FIGS. 2 to 9 schematically show a cross section of the pressing portion 2 arrangement position.

The panel portion 3 is formed of a translucent resin material or a glass material. Further, the panel portion 3 has an approximately planar shape having a thickness of 2.5 mm or less.

As shown in FIG. 2, the light guide portion 6 is provided on the surface 5 side opposite to the surface 4 that the user of the panel unit 3 contacts when pressed. The light guide unit 6 guides the light emitted from the light emitting unit 7 that emits light from the side surface to the left of the paper surface, and illuminates the pressing unit 2 to indicate to the user that the pressing unit 2 is a contact unit at the time of command input. Play a role. The light guide portion 6 material is formed of a resin material such as polystyrene.

The light guide unit 6 may have a configuration in which it directly contacts and abuts, for example, the three surfaces of the panel unit, or, as shown in FIGS. 3 and 4, a part or the entire region between the three surfaces of the panel unit and the light guide unit 6 is covered. It may be attached or adhered with a double-sided tape 8 or an adhesive 9. Alternatively, the light guide portion 6 may be supported on other than the three panel portions. For example, as shown in FIGS. 5 and 6, the light guide portion 6 may be attached to a member (for example, a substrate 18, an electrostatic switch 13) provided inside the device 1. A part or the entire area of the light guide portion 6 may be attached or adhered with a double-sided tape 8 or an adhesive 9.

Further, as shown in FIG. 2, the electrostatic switch 13 is provided on a surface opposite to the surface where the light guide portion 6 faces the panel portion 3. The electrostatic switch 13 may have a configuration in which the entire surface or a part of the light guide unit 6 is in direct contact with the light guide unit 6 and abuts the electrostatic switch 13, or a part or all of the electrostatic switch 13 and the light guide unit 6 as shown in FIGS. The region may be attached with a double-sided tape 14, an adhesive 15, or the like, or may be adhered.

Further, as shown in FIG. 2, the substrate 18 having the electrostatic switch 13 may have a configuration in which the entire surface or a part of the light guide portion 6 is in contact with and abuttes against the light guide portion 6, or as shown in FIGS. 5 and 6 described above. The 18 and a part or the whole area of the light guide portion 6 may be attached or adhered with a double-sided tape 14 or an adhesive 15.

Further, the support configuration of the substrate 18 is, for example, a member provided inside the device 1 (for example, an inner cover 10) provided with a claw 21 to support the substrate 18, or a member provided inside the device (for example, as shown in FIG. 7). The inner cover 10) may be supported by providing a member 22 (for example, pressing force by a spring) that presses the substrate 18 toward the light guide portion 6.

Further, as shown in FIG. 2, the inner cover 10 is provided on the surface 5 side opposite to the surface 4 that the user of the panel portion 3 contacts when pressed. The inner cover 10 is not translucent and is formed of, for example, a resin material. The inner cover 10 plays a role of supporting a part of the panel portion 3, and may be configured to directly contact and support the three panel portions, or as shown in FIG. 8, between the three panel portions and the inner cover 10. A part of the above may be attached with a double-sided tape 23, an adhesive 24, or the like, or may be adhered.

In this way, the inner cover 10 plays a role of blindfolding the parts arranged inside the panel portion 3 and also plays a role of increasing the rigidity of the panel portion 3.

Further, the inner cover 10 has recesses 25 in a part or a plurality of portions on the surface side facing the panel portion 3, and the inner cover 10 has recesses 25 in a part or a plurality of portions of the recesses 25 in a direction 27 approximately perpendicular to the user pressing direction 26. It has a light guide unit 6 arrangement area 28 to which the light guide unit 6 can be arranged. With such a configuration, it is sufficient to arrange the light guide member only on the user pressing portion 2, and it is not necessary to arrange the light guide member on the non-light emitting portion. In this way, the step of forming the coating layer and the colored layer on the non-light emitting portion can be eliminated.

The distance 31 between the side surface 29 of the light guide portion 6 and the side surface 30 of the inner cover 10 recess 25 facing each other is 1 mm or more. Further, in the region of the inner cover 10 recess 25 and the light guide portion arranging region 28, between the facing surface 5 of the panel 3 with the light guide portion 6 and the inner cover 10 and the facing surface 11 of the light guide portion 2 with the panel 3. The distance 12 is shorter than or equal to the distance 20 between the facing surface 5 of the light guide portion 6 of the panel 3 and the inner cover 10 and the facing surface 19 of the inner cover 10 of the panel 3. With such a configuration, in the user pressing unit 2, the distance between the electrostatic switch 13 and the user pressing contact surface 4 of the panel unit 3 can be defined by the dimensions of the light guide unit 6. Further, by setting the distance 31 between the side surface 29 of the light guide portion 6 and the side surface 30 of the inner cover 10 recess 25 to face each other to 1 mm or more, the unevenness of the inner cover 10 surface becomes uneven when the electrostatic switch 13 and the panel portion 3 are pressed by the user. The influence on the distance between the contact surfaces 4 can be reduced.

As a result, the distance between the electrostatic switch 13 and the contact surface 4 when the user is pressed can be accurately defined, and when the user presses the electrostatic switch 13, the electrostatic switch 13 can be reliably reacted.

Further, the combination of the support configuration of the panel unit 3, the light guide unit 6, the inner cover 10, the electrostatic switch 13, and the substrate 18 is not limited to the configuration shown in FIGS. 2 to 8, and the panel unit is, for example, as shown in FIG. The double-sided tape 8 to which the panel portion 3 and the light guide portion 6 are attached and adhered may be the same as the double-sided tape 23 to which the panel portion 3 and the inner cover 10 are attached and adhered. The support configuration of the substrate 18 may be a combination of the support configuration by the claws 21 provided on the inner cover 10, and a part or the entire region of the substrate 18 and the light guide portion 6 may be covered with double-sided tape 14, an adhesive 15, or the like. It may be attached or adhered to each other.
