[0133] For example, the second clamp 65 may be spaced downward from the first clamp 64 and may have the same shape as the first clamp 64. That is, the foregoing content regarding the first clamp 64 may be equally applicable to the second clamp 65. Thereby, the second center protrusion 65a, the second left protrusion 65b, and the second right protrusion 65c of the second clamp 65 generate friction between the vertical member 61 and the pole 30. 30.

[0134] Thereby, the position (height) of the vertical member 61 with respect to the base 20 is maintained constant by the frictional force between the protrusions 64a, 64b, 64c, 65a, 65b, 65c and the pole 30 unless an external force above a certain level is applied.

[0135] On the other hand, the lengths of the left protrusions 64b, 65b and the right protrusions 64c, 65c may be smaller than the lengths of the center protrusions 64a, 65a. Thereby, the pole 30 can include a plurality of ribs 30a, 30b, 30c, 30d, and the rigidity of the pole 30 can be sufficiently ensured. <00009​​​​​​​​​​​​​​​​​​They may be arranged along the m (63s, see Figure 21), and the b located inside the base 20 It is electrically connected to electronic components such as the battery (see Figure 1).

It may be an adjacent vertical axis. The user raises or lowers the head 10 on the pole 30. This can be done. Here, the minimum and maximum heights of the head 10 are formed on the pole 30. The hole 30hh is formed by the arm 50 being placed over it.

[0139] The pivot, tilt, swivel, and elevating movements of the aforementioned head 10 are relative to each other. It may be implemented independently. For example, head 10 pivots within the range of +90 degrees to -90 degrees. It can be tilted. For example, head 10 can be tilted within the range of +25 degrees to -25 degrees. It can be done. For example, head 10 can be swiveled within the range of +65 to -65 degrees. This is possible. For example, head 10 is based on horizontal mode, base 20 or 1,065 from the ground. It may be located at ~1,265 mm.

Such a wireless charging unit 19 Power is supplied from the power supply board Pu.

[0196] Inductive coupling is a method that uses two adjacent coils. If you change the strength of the current flowing through any one of the coils, A change in the magnetic field causes a change in the magnetic flux passing through another coil, resulting in an induced electromotive force. This method utilizes the principle by which this occurs. In other words, even without moving the two wires in space If you keep the two coils close together and change the current in only one of them, the other one will change. An induced electromotive force will be generated in one of the coils. In this case, the frequency characteristics will have a significant impact.

[0197] Resonance coupling is a method where the components are separated by a certain distance. The resonance frequency (Resonance Frequencies) of one of the two coils is determined. A portion of the magnetic field change generated by applying a certain frequency (ency) is transmitted to another coil with the same resonant frequency. This method utilizes the principle that an induced electromotive force is generated when an electric current is applied to a device. In other words, the transmitting and receiving device When they resonate at the same frequency, electromagnetic waves are transmitted by the near-field electromagnetic field, therefore the frequency If the numbers are different, there is no energy transfer. In this case, the choice of frequency can become an important issue. Furthermore, since there is no energy transfer between different resonant frequencies, charging can be achieved by selecting the resonant frequency. You can also select the target device.
