2. Description of the Related Art A conventional low-frequency therapeutic device having a plurality of electrodes is provided with one low-frequency pulse output means and output distribution means for deciding to which electrode the low-frequency output is distributed. However, there is a problem (Japanese Patent Laid-Open No. 3-9766) that the electrodes that output low frequency voltage are sequentially changed in a predetermined order to prevent current burns and muscle fatigue due to long-term use.

Further, in the conventional low-frequency treatment device having a plurality of low-frequency pulse output means, the low-frequency pulse output means including the power source and the electrodes correspond to each other in a one-to-one manner so that stimulation between the electrodes does not become scattered. There is a synchronizing signal generating circuit for synchronizing the output from each low-frequency pulse output means (Japanese Patent Laid-Open No. 3-277383).

A low-frequency therapeutic device having a plurality of electrodes and one low-frequency pulse output means is capable of stimulating only one pattern at a time, and stimulating five fingers. I couldn't create the different, delicate feelings of rubbing with my hands. Also, in a low frequency treatment device having a plurality of low frequency pulse output means, simply by synchronizing the output,
Since the intensity of the output voltage is adjusted separately, the number of operations increases as the number of low-frequency pulse output means increases, which deteriorates usability. For this reason, a control signal was sent from the parent treatment device or control unit to multiple child treatment devices to control the cycle and intensity of the low-frequency pulse, but the same signal was sent to multiple low-frequency treatment devices. Therefore, the pulse output intensity could not be changed separately, and it was not possible to create a delicate sensation of rubbing with the hands, in which the stimuli of the five fingers were different.

Further, since the low-frequency pulse output means including the power source and the electrodes correspond to each other on a one-to-one basis, when the stiffness position and the mounting position of the power source are deviated, the electrodes have to be replaced and the stimulation is arbitrarily performed. It didn't move the position.

In addition, in the operation unit of the conventional low frequency treatment device,
ON / OFF changeover switch or key, resistance volume is used, and when the user wants to receive a strong stimulus, he / she operates strongly, and when he / she wants to weaken the stimulus, he / she weakens the operation.

The second purpose is to change the output position to change the sensation of low-frequency stimulation and to create a finer sensation.

If there are as many output intensity control units as there are low-frequency pulse output means, the operation becomes complicated.
The control position such as the right side, the left side, and the center of the rubbing position is operated by dividing it into one block, and the waveform intensity is controlled by one output intensity control means to reduce the number of operating parts. A third object is to simplify the operation while changing the number and combination of the low-frequency pulse output means controlled by one block depending on the waveform mode to create a sensation by finer stimulation while simplifying the operation. Is.

Further, in order to simplify the operation, the output intensity control means for controlling the output intensity of a plurality of blocks such as the front, rear, and middle blocks is controlled by a single operating section to control the intensity of a plurality of blocks. A fourth object is to change the strength of each part such as front, back, and center at a predetermined ratio to simplify the strength control of each part.

Further, if the strength operation section is strongly pressed, the stimulus becomes strong, and if the strength operation section is weakly pressed, the stimulus becomes weak. The fifth purpose is to change the output intensity with and to simplify the operation.

Further, a plurality of electrodes are arranged in one row, and the plurality of electrodes are mounted in a plurality of rows, and the electrodes (1, 13; 2, 14, etc.) facing each other from the low frequency pulse output means or the adjacent electrodes (1, 2; 13). , 14) to output a low-frequency pulse having the same or different waveform pattern, switch the low-frequency output means and the electrode with the lapse of a predetermined time, and sequentially move the position of the electrode to be output to the adjacent electrode. By moving the stimulus by, rubbing, rubbing, moving the place to hit, without changing the electrodes, and creating a stimulus similar to rubbing and hitting by a person with low frequency pulse output means less than the number of electrodes Is the sixth object.

In addition, two electrodes that are adjacent and close to each other are
As a set, by applying a low frequency stimulus from each low frequency pulse output means corresponding to one set of one electrode, the position of one set of electrodes is stimulated with a finger and the low frequency stimulus is applied to five sets of electrodes. The seventh purpose is to create a feeling of rubbing with five fingers.

An eighth object is to make it possible to change the stimulation position when it is desired to change the stimulation point while the fixed position is stimulated.
