(Embodiment 1)
Embodiment 1 of the present invention will be described with reference to FIG. FIG. 1 is a diagram showing a configuration of electronic glasses according to Embodiment 1 of the present invention. The electronic glasses shown in this figure include a variable focus lens 1 whose focus is switched by a voltage signal, a frame rim 2 for fixing the variable focus lens 1, a switch 3 below the frame rim 2, and an upper portion of the frame rim 2. Switches 4 and 5, a nose pad 6 attached to the nose position of the frame rim 2, a temple 7 connected to the frame rim 2, and a position near the connection position between the frame rim 2 and the temple 7. And an electronic circuit (not shown).

  Here, the three switches of the lower switch 3 and the upper switches 4 and 5 of the frame rim 2 are connected to the electronic circuit through the transparent electrode on the inside of the frame rim 2 or on the surface of the variable focus lens 1.

  The electronic circuit is supplied with electric power from a battery (not shown), and when the lower switch 3 and the upper switches 4 and 5 are all pressed, a voltage is applied to the variable focus lens 1 from the driver circuit in the electronic circuit. Then, the focus is switched. The modes such as the far field, the near field, and the power-off are sequentially switched from the current state to the next state each time these switches 3, 4, and 5 are pressed. The switches 3, 4, and 5 may be an electrode sensor that detects contact resistance with human skin, a touch sensor that uses a piezoelectric material to convert pressure into an electrical signal, a mechanical push sensor, or the like. Further, the switches 3, 4, and 5 are formed with a concave or convex surface on the switch surface so that the position of each switch can be easily identified when the electronic glasses are put on the face. Therefore, the position of each switch can be easily confirmed by the touch of the fingertip.

  The varifocal lens 1 is a liquid crystal lens that switches a focus using a liquid crystal whose refractive index changes depending on a voltage, or an elastic lens that switches a focus by changing the curvature of the elastic body by controlling pressure from the outside to an elastic body containing liquid. Etc. can be used.

  Next, the operation in Embodiment 1 of the present invention will be described. In the electronic spectacles in which the three switches of the electronic spectacles are installed on the rim 2 of the right frame, when it is desired to switch the focus while the electronic spectacles are worn, the thumb of the right hand is placed on the rim 2 of the frame. When the index finger is moved to the upper switch 4 and the ring finger is moved to the upper switch 5 when the three fingers touch all the switches, the electric circuit is instructed to switch the focus and the variable focus lens 1 is moved to the lower switch 3. A voltage is applied to and the focus is switched. At this time, the position of the switch installed on the rim 2 of the frame is not visible, but since the concave or convex object is provided on the surface of the switch, the position can be determined by touching the finger.

Next, the operation in Embodiment 2 of the present invention will be described. When the three switches 3, 4, and 5 are placed on the face of the electronic glasses installed on the right rim 2, when the focus is to be switched, the following operation is performed. The thumb of the right hand is moved to the switch 3 at the lower part of the rim 2, the index finger is moved to the upper switch 5, and the ring finger is moved to the upper switch 4. The three fingers press all the switches. When this operation is performed, a focus switching command is issued to the electric circuit, and a voltage is applied to the variable focus lens 1 to switch the focus. At this time, since the position of the switch installed on the rim 2 is not visible, a concave or convex object is provided on the surface of the switch. This is so that the position of the switch can be recognized by touching the finger. By providing one switch at the bottom and two at the top, the bottom switch is the thumb and the top switch is the index and middle fingers. Each switch can be operated reliably with a comfortable posture. On the other hand, normally, when a person unconsciously adjusts the position of the glasses, he or she touches the glasses with one or two fingers, so the three switches arranged as described above are consciously operated at the same time. There is a need. Therefore, with such an arrangement, it is less likely that the focus switch is turned on by mistake.

  The distance between the switches 4 and 5 at the top of the rim 2 of the frame is two fingers if the distance between the centers of the two switches is more than the length corresponding to the width of the tip of the human index finger or ring finger. Can touch switches to be operated separately without touching each other. Furthermore, by installing the lower switch 3 below the position corresponding to the middle between the upper switches 4 and 5, the three rims 2 of the frame rim 2 can be more comfortable with the three fingers of the thumb, index finger and ring finger. It is possible to operate several switches.

  Here, three switches are provided in the upper part and two in the lower part. However, even in a configuration in which the upper part is provided in one place and sandwiched between two fingers, erroneous input of the switch is remarkably reduced. In the operation example, the switch is arranged on the rim 2 of the right frame, and the switch is operated with the right hand. However, the rim 2 of the frame on which the switch is installed and the hand for operating the switch may be either left or right.

(Embodiment 2)
A second embodiment of the present invention will be described with reference to FIG. FIG. 2 is a diagram showing the configuration of the electronic glasses according to Embodiment 2 of the present invention. The electronic glasses shown in this figure include a variable focus lens 1 whose focus is switched by a voltage signal, a frame rim 2 for fixing the variable focus lens 1, a temple 7 connected to the frame rim 2, and a lower portion of the temple 7. An electronic circuit (near the connection position between the rim 2 of the frame 7 and the temple 7, the switch 8, the switches 9, 10 at the top of the temple 7, the nose pad 6 attached to the nose position of the frame rim 2 (Not shown).

  Here, the three switches of the lower switch 8 and the upper switches 9 and 10 of the temple 7 are connected to the electronic circuit through the temple 7, respectively.

  The electronic circuit is supplied with power from a battery (not shown), and when the lower switch 8 and the upper switches 9 and 10 are all pressed, a voltage is applied from the driver circuit of the electronic circuit to the variable focus lens 1. The focus is switched. The modes such as the far field, the near field, and the power-off are sequentially switched from the current state to the next state every time the switches 8, 9, and 10 are pressed.

  The switches 8, 9, and 10 can be an electrode sensor that detects contact resistance with human skin, a touch sensor that uses a piezoelectric material to convert pressure into an electrical signal, a mechanical push sensor, or the like. Further, the switches 8, 9, and 10 have a concave or convex surface formed on the switch surface, and the position of the switch can be confirmed by the touch of the fingertip, so that the switch that cannot be visually recognized when wearing the electronic glasses can be recognized. The varifocal lens 1 is a liquid crystal lens that switches a focus using a liquid crystal whose refractive index changes depending on a voltage, or an elastic lens that switches a focus by changing the curvature of the elastic body by controlling pressure from the outside to an elastic body containing liquid. Etc. can be used.

  Next, the operation in Embodiment 2 of the present invention will be described. When the electronic switches installed on the right temple 7 with the three switches 8, 9, 10 are put on the face, the focus is switched as follows. The thumb of the right hand is moved to the switch 8 at the lower part of the temple 7, the index finger is moved to the upper switch 10, the ring finger is moved to the upper switch 9, and the three fingers press all the switches. When this operation is performed, a focus switching command is issued to the electric circuit, and a voltage is applied to the variable focus lens 1 to switch the focus. At this time, since the position of the switch installed on the temple 7 is not visible, a concave or convex object is provided on the surface of the switch. This is because the position of the switch can be recognized by touching the finger.

  By providing one switch on the lower part and two on the upper part, the lower switch can be pressed with the thumb and the upper switch can be pressed with the index and middle fingers, and each wrist switch can be operated with a comfortable posture. Can do. On the other hand, normally, when a person unconsciously adjusts the position of the glasses, he or she touches the glasses with one or two fingers, so the three switches arranged as described above are consciously operated at the same time. There is a need. Therefore, with such an arrangement, it is less likely that the focus switch is turned on by mistake.

  The distance between the switches 9 and 10 on the upper part of the temple temple 7 is two fingers if the distance between the centers of the two switches is more than the length corresponding to the width of the tip of the human index finger or ring finger. Can touch switches to be operated separately without touching each other. Further, by installing the lower switch 8 below the position corresponding to the middle between the upper switches 9 and 10, the temple 7 of the frame 7 is more comfortable with three fingers of the thumb, index finger and ring finger. It is possible to operate several switches.

  Here, three switches are provided at the upper part and two at the lower part, but erroneous input of the switch is remarkably reduced even in a configuration in which the upper part is provided at one place and is sandwiched between two fingers. In the operation example, the switch is arranged on the right temple 7 and the switch is operated with the right hand. However, the temple 7 for installing the switch and the hand for operating the switch may be either left or right.

  As described above, according to the present invention, for the purpose other than the electrical function switching of the electronic spectacles, even if the user touches the electronic spectacles, the malfunction is not likely to occur, and the electrical function switching such as comfortable focus switching is possible. It can be carried out.

  The electronic glasses according to the present invention are arranged by dividing a plurality of switches into the upper and lower parts of the rim or temple of the frame of the electronic glasses, and by switching the electrical function when all of the plurality of switches are turned on, This is useful for electronic perspective glasses that are unlikely to malfunction even when the user touches the electronic glasses for purposes other than switching the functions of the electronic glasses.
