The reference electrode 146 may be an example of a second electrode.

  The battery 148 is electrically connected to the circuit board 138 through the right temple 140, the front 120, and the left temple 130.

  FIG. 3 schematically shows a state where the wearer 10 is wearing the glasses 100. As shown in FIG. 3, the eyebrow electrode 166 contacts the eyebrow space 12 of the wearer 10. Further, the left electrode 162 contacts the nose 14 of the wearer 10. Similarly, the right electrode 164 contacts the nose 14 of the wearer 10. The ground electrode 136 is in contact with the back side of the left ear 16 of the wearer 10. Similarly, the reference electrode 146 contacts the back side of the right ear 16 of the wearer 10.

  The ground electrode 136, the reference electrode 146, the left electrode 162, the right electrode 164, and the inter-brow electrode 166 are always reliable so as to continuously detect the biological signal of the wearer 10 while the wearer 10 is wearing the glasses 100. It is desirable to contact the wearer 10. Therefore, the glasses 100 according to the present embodiment maintain the contact of the ground electrode 136, the reference electrode 146, the left electrode 162, the right electrode 164, and the interbrow electrode 166 by having the rope-type modern 132 and the rope-type modern 142. .

  FIG. 4 schematically shows the glasses 100 before and after wearing. As shown, the rope wire 134 may have an arcuate shape. Rope wire 134 has an elastic force that presses ground electrode 136 against the back side of ear 16 of wearer 10 when worn by wearer 10.

  As a result, the ground electrode 136 can be prevented from being separated from the wearer 10. Further, since the rope wire 134 has an elastic force that presses the ground electrode 136 against the back side of the ear 16, the interbrow electrode 166 can be pulled toward the interbrow 12. That is, the head of the wearer 10 can be sandwiched between the inter-brow electrode 166 and the ground electrode 136 by the elastic force of the rope wire 134. Thereby, it is possible to prevent the eyebrow electrode 166 from being separated from the eyebrow space 12 while preventing the ground electrode 136 from being separated from the back side of the ear 16.

  The ground electrode 136 may have a spherical shape. Thereby, it is possible to prevent the ear 16 from being damaged by pressing the ground electrode 136 against the back side of the ear 16. The ground electrode 136 may have another shape as long as the ear electrode 16 can be prevented from being damaged when pressed against the back of the ear 16. For example, the ground electrode 136 has an ellipsoidal shape. The ground electrode 136 may have a shape with a smooth surface at least in contact with the back side of the ear 16.

  In FIG. 4, the rope hand wire 134 and the ground electrode 136 are described among the rope hand wire 134 and the ground electrode 136, and the rope hand wire 144 and the reference electrode 146, but the same applies to the rope hand wire 144 and the reference electrode 146.

  FIG. 5 schematically shows an example of the interbrow electrode unit 156. The interbrow electrode unit 156 may include an elastic member 157 and a wiring 158. The elastic member 157 is installed on the frame 110 and holds the inter-brow electrode 166. The wiring 158 electrically connects the wiring 150 embedded in the frame 110 and the interbrow electrode 166. The wiring 150 electrically connects the wiring 158 and the circuit board 138.

  Since the elastic member 157 holds the eyebrow electrode 166, the pressure applied to the eyebrow 12 by the eyebrow electrode 166 attracted to the wearer 10 side by the rope hand wire 134 and the rope hand wire 144 can be absorbed. Accordingly, it is possible to prevent excessive pressure from being applied to the eyebrow space 12 while preventing the eyebrow electrode 166 from being separated from the eyebrow space 12.

  The elastic member 157 may be any member as long as it has elasticity. For example, the elastic member 157 is an elastomer resin.

  FIG. 6 schematically shows another example of the interbrow electrode unit 156. The eyebrow electrode unit 156 may include a conductive member 159 having elasticity and a wiring joint 160. The conductive member 159 and the wiring joint 160 are installed on the frame 110. The conductive member 159 holds the eyebrow electrode 166. The wiring joint 160 electrically connects the conductive member 159 and the wiring 150. The wiring 150 electrically connects the wiring joint 160 and the circuit board 138.

  When the conductive member 159 holds the eyebrow electrode 166, the pressure applied to the eyebrow 12 by the eyebrow electrode 166 attracted to the wearer 10 by the rope hand wire 134 and the rope hand wire 144 can be absorbed. Accordingly, it is possible to prevent excessive pressure from being applied to the eyebrow space 12 while preventing the eyebrow electrode 166 from being separated from the eyebrow space 12.

  The conductive member 159 may be any member as long as it has elasticity and conductivity. For example, the conductive member 159 is a conductive sponge. Further, the conductive member 159 may be a conductive rubber. The conductive member 159 may be a conductive resin having elasticity.

  In the present embodiment, the example in which the ground electrode 136 is installed at the distal end of the rope hand wire 134 and the reference electrode 146 is installed at the distal end of the rope hand wire 144 has been described, but the present invention is not limited thereto. The ground electrode 136 may be installed at a location other than the tip of the rope-line wire 134. In addition, the reference electrode 146 may be installed at a place other than the tip of the rope hand wire 144.

  Further, in the present embodiment, the case where the left temple 130 has the ground electrode 136 and the right temple 140 has the reference electrode 146 has been described as an example. However, the left temple 130 has the reference electrode 146 and the right temple 140 may have a ground electrode 136. In the present embodiment, the case where the left temple 130 includes the circuit board 138 and the right temple 140 includes the battery 148 has been described as an example. However, the left temple 130 includes the battery 148 and the right temple 140 includes the battery 148. A circuit board 138 may be included.
