On the other hand, on the surface of the printed circuit board 10 on the side where the printed body 10 is attached to the adhered part such as the body, as shown in detail in FIG. 3, the unit side first charging terminal 20 and the unit side second charging terminal are provided in the central portion thereof.
21 are arranged, and an antenna 23 is arranged on the outer peripheral portion thereof, and each is electrically connected to the IC circuit pattern through a through hole 22. Both terminals 20,21
Since it is exposed, there is no need to connect it when charging. The charging terminals 20 and 21 and the antenna 23 are all formed by a printing technique. The unit-side first charging terminal 20 is located in the center of the printed circuit board 10, and the unit-side second charging terminal 21 is located concentrically on the outer periphery thereof. The unit-side first charging terminal 20 has a perfect circular shape, but the unit-side second charging terminal 21 has a circumference of about 27 mm.
It has a C-shape extending at 0 degrees. As described above, since the unit-side second charging terminal 21 is formed in the C-shape instead of the perfect ring shape, the high frequency eddy current loss generated by the antenna 23 does not occur. The unit-side first charging terminal 20 and the unit-side second charging terminal 21 are configured so as not to be broken by a short circuit even if the unit case is attached to the body for bathing or sweat adheres. The antenna 23 is formed in a spiral shape so as to surround both charging terminals 20 and 21 provided in the central portion of the printed board 10 from the outer circumference.

As shown in the removed state in FIGS. 4 and 5, the protective sheet 25 has a circular first through hole 26 in the center thereof, which is similar to the unit-side first charging terminal 20 on the outer circumference. Then, it is provided with an arc-shaped second through hole 27 whose size is also slightly smaller. In the protective sheet 25, the first through hole 26 is concentrically located in the center of the circular unit-side first charging terminal 20, and the second through hole 27 is in the center of the width of the unit-side second charging terminal 21. The printed circuit board 10 and the large-diameter-side step portion 5 are mounted by adhesion so as to be positioned. Here, the protective sheet 25 is more securely fixed to the step portion 5 with an ultrasonic welder so that the protective sheet 25 is held securely and the waterproof insulation is improved. The first through hole 26 and the second through hole 27 of the protective sheet 25 are not located at the stepped portion of each copper foil pattern forming the unit side first charging terminal 20 and the unit side second charging terminal 21 of the printed circuit board 10, Since it is bonded inside the flat surface inside, the protective sheet 25
It does not come off or come off, providing a more reliable waterproof effect.

On the body-mounting surface side of the unit case 1, a mounting member that is breathable like a polyurethane foam material and that can be deformed according to the shape of the skin surface to prevent mechanical rashes.
31 is attached so that it can be removed and replaced. This mounting member
31 is a thin ring having a circular vent 32 at its center. The mounting member 31 has an adhesive on both front and back surfaces.

Each control for preventing overcharge of the rechargeable battery 18 based on the voltage detection between 1 is performed. As shown in the operation flow of those circuit configurations in FIG. 7, it is used that while the rechargeable battery 18 has a power supply voltage, electromagnetic waves are radiated from the antenna 23 through the oscillation circuit section 83 and are in the operating state. LED14 is turned on by the LED lighting circuit to inform the person. This is confirmed through the operation confirmation window 17 of the unit case 1. If it is recognized that the electromagnetic wave oscillation is stopped by turning off the LED 14, the treatment device unit A can be set in the charger B and charging can be performed. When the charging voltage detection circuit 81 is built in the treatment device unit A side when it is set in the charger B when the LED 14 lights up and the electromagnetic wave oscillates, this circuit 81 is connected between the charging terminals 20 and 21. By detecting the voltage input from the charger B by the voltage detection, the oscillation of the electromagnetic wave is stopped through the operation control circuit section 82 also incorporated in the treatment unit A, and the LED1
Turn off 4 This prevents wasteful power consumption. When charging is started from the dry battery (charging power source) 56 to the charger 18 of the treatment device unit A through the contact terminals and the charging terminals 20 and 21, the operation control circuit unit 82 lights the charging indicator lamp 79 of the charger B. To inform the user that the battery is charging. When it detects that the voltage of the rechargeable battery 18 is equal to or higher than the stipulated value or that the charging time has exceeded a predetermined time, the charging of the rechargeable battery 18 is stopped to prevent overcharging and the charger B is being charged. The indicator lamp 79 is also turned off to notify the user that charging is completed.
