The voltage output circuit 10 operates by receiving power from the power supply 30.

  The power supply 30 is a button-type lithium ion battery, and may be a primary battery or a secondary battery. The power source 30 has an electromotive force of 3 [V], for example, and is accommodated inside a box formed by the upper cover 1 and the lower cover 2 by opening the battery cover 9. The power supply 30 supplies power to each unit. In addition, the power supply 30 outputs a voltage to the booster 34.

  The power signal output unit 31 is a switch joined to the power button 3, and outputs two types of instruction signals indicating that the power button 3 has been pressed when the power button 3 is pressed. The power signal output unit 31 outputs a start signal to the operation control unit 41 when the power button 3 is pressed for a long time of, for example, 2 [seconds] or longer, and presses the power button 3 for a short time of, for example, less than 2 [seconds]. In the case of the failure, the mode signal is output to the switch control unit 43 and the pulse control unit 44.

  The plus signal output unit 32 is a switch joined to the plus button 4. When the plus button 4 is pressed, the plus signal output unit 32 outputs an instruction signal indicating that the plus button 4 has been pressed to the voltage control unit 42.

  The minus signal output unit 33 is a switch joined to the minus button 5, and outputs an instruction signal indicating that the minus button 5 has been pressed to the voltage control unit 42 when the minus button 5 is pressed.

  The power supply 30 is a button-type lithium ion battery, and may be a primary battery or a secondary battery. The power source 30 has an electromotive force of 3 [V], for example, and is accommodated inside a box formed by the upper cover 1 and the lower cover 2 by opening the battery cover 9. The power supply 30 supplies power to each unit. In addition, the power supply 30 outputs a voltage to the booster 34.

  The booster 34 boosts the voltage input from the power supply 30. The voltage value boosted by the boosting unit 34 is set in advance, for example, in six stages of 13, 19, 25, 33, 41, and 49 [V]. The boosting unit 34 boosts the voltage value according to the instruction signal from the voltage control unit 42 and outputs the boosted voltage value to the pulse output unit 35.

  The pulse output unit 35 controls to turn on or off the output of the voltage boosted by the boosting unit 34. The pulse output unit 35 outputs the voltage boosted by the boosting unit 34 to the first switch group 61 in accordance with an instruction signal input from the pulse control unit 44.

  The ground part 36 is a part where the potential is maintained at the ground potential. The ground unit 36 is connected to the first switch group 62. The ammeter 37 measures the value of the current flowing between the electrode connected to the pulse output unit 35 and the electrode connected to the ground unit 36. The ammeter 37 outputs the measured current value to the impedance calculation unit 45.

  The control unit 40 is a CPU (Central Processing Unit). Each unit is controlled by reading and executing the program and other various data stored in the storage unit 50.

  The ROM 51 is a mask ROM or PROM (Programmable ROM). The ROM 51 stores an operation program for the control unit 40 and also stores an impedance threshold, a level table, and a mode table.

  The RAM 52 is a DRAM (Dynamic RAM) or an SRAM (Static RAM). In addition to various data generated during execution of the control program, the RAM 52 stores level information indicating the level and mode information indicating the mode.

  The operation control unit 41 controls the power supply state from the power supply 30 to each unit so as to enter either the standby state or the operation state. The standby state is a state where the input of the activation signal is waited and other parts are not operating, and the operating state is a state where each part is operating. Further, the operation control unit 41 has a time measuring function. When an activation signal is input from the power signal output unit 31 to the operation control unit 41, the operation control unit 41 starts measuring time. When the instruction signal instructing to enter the standby state is input from the impedance calculation unit 45, the operation control unit 41 stops the power supply to each unit and sets the standby state.

  Further, the operation control unit 41 stops supplying power to each unit when a certain time elapses, for example, 10 [minutes] after the start of timing, and switches from the operation state to the standby state. If stimulation with electric current is performed for a long time, the body may be disturbed. Therefore, the operation control unit 41 forcibly ends the stimulation by the current when a certain time has elapsed.

  The voltage control unit 42 controls the boosting unit 34 and the second display unit 7. The voltage control unit 42 outputs an instruction signal instructing to output a predetermined voltage value to the boosting unit 34 in accordance with the instruction signals input from the plus signal output unit 32 and the minus signal output unit 33. Further, the voltage control unit 42 outputs an instruction signal to the second display unit 7 so as to perform display according to the voltage value.

  The switch control unit 43 has the switches 61a, 61b, 61c of the first switch group 61 and the switches 62a, 62b of the second switch group 62 in a predetermined cycle according to the mode signal input from the power signal output unit 31. Control 62c to be turned on or off.

  The pulse control unit 44 controls the pulse output unit 35 to output a pulse signal at a predetermined cycle according to the mode signal input from the power supply signal output unit 31.

  The impedance calculator 45 calculates an impedance value based on the current value input from the ammeter 37 and the voltage value input from the booster 34. The impedance calculation unit 45 outputs the calculated impedance value to the comparison unit 46. Instead of the voltage value boosted by the boosting unit 34, the voltage value set by the voltage control unit 42 may be input to the impedance calculation unit 45 from the voltage control unit 42.

  When the impedance value is input from the impedance calculation unit 45, the comparison unit 46 reads a threshold value for impedance from the ROM 51. The comparison unit 46 compares the impedance value input from the impedance calculation unit 45 with the threshold value read from the ROM 51. If the comparison unit 46 determines that the impedance value input from the impedance calculation unit 45 is equal to or greater than the threshold value read from the ROM 51 as a result of the comparison, the comparison unit 46 sends an instruction signal to instruct the operation control unit 41 to stop the operation. Output.

  If the comparison unit 46 determines that the impedance value input from the impedance calculation unit 45 is less than the threshold value read from the ROM 51 as a result of the comparison, the comparison unit 46 continues the operation without outputting an instruction signal.

  When the body is dry, the impedance value is generally high. In such a case, if an electric current is passed through the body, the user may feel pain. Therefore, when the impedance value is equal to or greater than the predetermined threshold value, the operation control unit 41 stops the operation of the voltage generator 100 based on the instruction signal input from the comparison unit 46.

  The switch unit 60 includes two sets of a first switch group 61 and a second switch group 62 in which three switches having the same number as the electrodes 8 are combined. One end of each switch 61a, 61b, 61c in the first switch group 61 is electrically connected to the pulse output unit 35, and the other end is connected to the first electrode 8a, the second electrode 8b, and the third electrode 8c, respectively. Has been. Each switch 62a, 62b, 62c in the second switch group 62 has one end connected to the grounding portion 36 and the other end connected to the first electrode 8a, the second electrode 8b, and the third electrode 8c, respectively. Yes. The switches 61a, 61b, 61c and the switches 62a, 62b, 62c are turned on or off according to the instruction signal output from the switch control unit 43, respectively. The location where the other ends of the switches 62a, 62b, 62c in the second switch group 62 are connected is not limited to the ground portion 36, but may be connected to a location having a lower potential than the voltage output from the booster 34.

  In FIG. 5, the switch 61a and the switch 62b are turned on. Then, the pulse output unit 35 and the first electrode 8a are connected, and the ground unit 36 and the second electrode 8b are connected. In such a case, when contacting the human body via a sheet-like electrode described later, current flows between the first electrode 8a and the second electrode 8b and impedance by the human body is generated. FIG. 5 is an example, and any one of the switches 61a, 61b, and 61c is turned on to turn on any one of the electrodes connected to the pulse output unit 35 and the switches 62a, 62b, and 62c.

Thus, the outer surface of the lower cover 2 is a flat surface, and when the voltage output device 100 and the sheet-like electrode 200 are joined, the outer surface of the insulating sheet 21 and the outer surface of the lower cover 2 are in contact with each other. Since it opposes, the sheet-like electrode 200 becomes easy to bend according to the shape of the body to contact. Thereby, skin and the electrically conductive sheet 22 become easy to adhere | attach.

  Since the first electrode 8a, the second electrode 8b, and the third electrode 8c and the first terminal 23a, the second terminal 23b, and the third terminal 23c are provided on a straight line at equal intervals, the voltage output device 100 and The sheet-like electrode 200 can be fitted in the opposite direction. That is, the third terminal 23c, the second terminal 23b, and the first terminal 23a can be fitted into the first electrode 8a, the second electrode 8b, and the third electrode 8c, respectively. Depending on the part of the body that comes into contact with the sheet-like electrode 200, the direction of the voltage output device 100 and the sheet-like electrode 200 may be more difficult to peel off or easier to operate. It is comprised so that.

  An operation process of the voltage control unit 42 will be described. FIG. 16 is a flowchart showing an operation process of the voltage control unit 42. The voltage control unit 42 determines whether or not an instruction signal is input from the plus signal output unit 32 (S1). When the instruction signal is not input from the plus signal output unit 32 (NO in S1), the voltage control unit 42 determines whether the instruction signal is input from the minus signal output unit 33 (S2). When the instruction signal is not input from the minus signal output unit 33 (NO in S2), the voltage control unit 42 returns to Step S1.

The voltage control unit 42 determines whether or not the level number indicated by the level information is the lowest level 1 (S8).

If the power supply is not stopped (NO in S14), the voltage control unit 42 returns to S1 and continues the process. When the power supply is stopped (YES in S14), the voltage control unit 42 ends the process.

Thereafter, in 4.4 [seconds], the first electrode 8a is turned off, the second electrode 8b is set to a low potential, and the third electrode 8c is set to a high potential. Thereafter, for 6 [seconds], the first electrode 8a is set to a low potential, the second electrode 8b is set to a high potential, and the third electrode 8c is turned off.

  In mode 5, the pulse pattern continues with 25 [Hz] turned on for 0.2 [seconds] and turned off for 0.2 [seconds]. The first display unit 6 blinks red. In the switch pattern, the first electrode 8a is set to a high potential, the second electrode 8b is turned off, and the third electrode 8c is set to a low potential for 10 seconds from the start in one cycle. After 10 seconds, the first electrode 8a is set to a low potential, the second electrode 8b is turned off, and the third electrode 8c is set to a high potential.

Thereafter, for 10 seconds, the first electrode 8a is set to a low potential, the second electrode 8b is turned off, and the third electrode 8c is set to a high potential.

  When the power button 3 is pressed for a long time in the standby state, the power signal output unit 31 outputs a start signal to the switch control unit 43 and the pulse control unit 44. The pulse control unit 44 creates information indicating mode 1 when an activation signal is input. The pulse controller 44 stores mode information indicating mode 1 in the RAM 52.

  Further, the pulse control unit 44 reads the mode table from the ROM 51 when activated. The pulse control unit 44 refers to the mode table and outputs to the pulse output unit 35 an instruction signal for instructing output using a pulse pattern corresponding to mode 1.

  In the pulse pattern corresponding to mode 1, the period between on and off is 5 [Hz] from the start to 8 [seconds], and then the period between on and off is 25 until 17.6 [seconds]. A pulse of [Hz] is output. Here, when the cycle of on and off is 5 [Hz], the operation of turning on for 100 [μ seconds] and turning off for 100 [μ seconds] is repeated. When the cycle of ON and OFF is 25 [Hz], the operation of turning ON for 25 [μ seconds] and turning OFF for 15 [μ seconds] is repeated.

  FIG. 18 is a graph showing a potential difference between the third electrode 8c and the second electrode 8b in mode 1. It is assumed that a pulse of 13 [V] corresponding to level 1 is output from the pulse output unit 35. The horizontal axis of the graph represents time [second], and the vertical axis represents potential difference [V]. From the start to 8 [seconds], the potential difference of 13 [V] and 0 [V] are alternately repeated every 100 [μs]. From 8 [seconds] to 17.6 [seconds], the state in which the potential difference continues for 13 [V] for 25 [μseconds] and 0 [V] for 15 [μseconds] is alternately repeated.

  In addition, the pulse control unit 44 outputs an instruction signal that instructs the first display unit 6 to continuously turn on the green LED and turn off the red LED. When the instruction signal is input from the voltage control unit 42, the first display unit 6 continuously turns on the green LED and turns off the red LED in accordance with the instruction signal input from the pulse control unit 44.

  Further, when activated, the switch control unit 43 reads the mode table from the ROM 51. The switch control unit 43 refers to the mode table and outputs to the switch unit 60 an instruction signal instructing output according to the switch pattern corresponding to mode 1.

  A switch pattern corresponding to mode 1 will be described. In the switch pattern corresponding to mode 1, the first electrode is set to a high potential, the second electrode is turned off, and the third electrode is set to a low potential for 8 [seconds] from the start. Therefore, the switch unit 60 to which the instruction signal is input from the switch control unit 43 turns on the switch 61a of the first switch group 61 so that the pulse output unit 35 and the first electrode 8a are connected. Further, the switch 62c of the second switch group 62 is turned on so that the ground portion 36 and the third electrode 8c are connected. Turn off the other switches.

  19 and 20 are explanatory diagrams showing the flow of current. In FIG.19 and FIG.20, the sheet-like electrode 200 has adhere | attached on a part of skin. As shown by an arrow in FIG. 19A, when the first electrode 8a is at a high potential, the second electrode 8b is off, and the third electrode 8c is at a low potential, the first electrode 8a is electrically connected to the third electrode from the first conductive portion 22a. A current flows toward the third conductive portion 22c that is electrically connected to 8c. Such a current is a pulse current, and the current flows when the voltage output from the pulse output unit 35 is on. When the voltage is off, the first electrode 8a and the third electrode 8c are equipotential. Does not flow. Accordingly, a pulse current flows from the first conductive portion 22a to the third conductive portion 22c.

  From 8 [seconds] to 11.2 [seconds], the first electrode 8a is turned off, the second electrode 8b is set at a low potential, and the third electrode 8c is set at a high potential. Therefore, the switch unit 60 to which the instruction signal is input from the switch control unit 43 turns on the switch 61c of the first switch group 61 so that the pulse output unit 35 and the third electrode 8c are connected. Further, the switch 62b of the second switch group 62 is turned on so that the ground portion 36 and the second electrode 8b are connected. Turn off the other switches. As shown by an arrow in FIG. 19B, when the first electrode 8a is off, the second electrode 8b is at a low potential, and the third electrode 8c is at a high potential, the third conductive portion 22c that is electrically connected to the third electrode 8c inside the body. Current flows from the first electrode 8b toward the second conductive portion 22b.

  From 11.2 [seconds] to 14.4 [seconds], the first electrode 8a is at a low potential, the second electrode 8b is at a high potential, and the third electrode 8c is turned off. Therefore, the switch unit 60 to which the instruction signal is input from the switch control unit 43 turns on the switch 61b of the first switch group 61 so that the pulse output unit 35 and the second electrode 8b are connected. Further, the switch 62a of the second switch group 62 is turned on so that the ground portion 36 and the first electrode 8a are connected. Turn off the other switches. As shown by the arrow in FIG. 19C, when the first electrode 8a is at a low potential, the second electrode 8b is at a high potential, and the third electrode 8c is off, the second conductive portion 22b that is electrically connected to the second electrode 8b inside the body. Current flows from the first electrode 8a toward the first conductive portion 22a.

  From 14.4 [seconds] to 17.6 [seconds], similarly to the time from 8 [seconds] to 11.2 [seconds], the switch control unit 43 turns off the first electrode 8a, and the second electrode 8b is set to a low potential, and the third electrode 8c is set to a high potential. Accordingly, a current flows through the switch unit 60 to which the instruction signal is input from the switch control unit 43 as shown in FIG. 19B.

  The switch control unit 43 outputs an instruction signal to the switch unit 60 so as to periodically repeat the above-described operation with 17.6 [seconds] as one cycle. The switch unit 60 to which the instruction signal is input from the switch control unit 43 turns on the switches 61a, 61b, 61c of the first switch group 61 and the switches 62a, 62b, 62c of the second switch group 62 according to the switch pattern. Or control off.
