As described above, in the prior art, since there are several types of vibration patterns to be selected, it is necessary to obtain an intermediate vibration pattern between a certain vibration pattern and the next vibration pattern. Could not. Therefore, since the vibration pattern cannot be finely changed, there is a problem in that the range of options for obtaining the vibration pattern is narrow, and it is not possible to sufficiently respond to the user's preference. This problem can be improved by increasing the number of microcomputer programs. However, in such a case, the development of the program software requires a large amount of cost, which increases the cost, and therefore, a practical measure is required. is not. SUMMARY OF THE INVENTION An object of the present invention is to provide an easy-to-use lubrication device that can continuously change the vibration pattern of a vibrator and can respond more finely to a user's preference.

In this configuration, the resistance value of the variable resistor is arbitrarily adjusted by the user in the operation section, and the output voltage according to the resistance value is converted into a digital value by the A / D converter. This digital value is used as an independent variable of a function determined by the calculation unit, and therefore, the calculation unit calculates the vibration time and the vibration pause time of the vibrator of the vibratory rubbing machine according to the resistance value. The periodic signal generating section forms an operation signal having the same cycle as the rectified waveform of the rectified output obtained based on the alternating current. Further, the drive signal supply unit outputs a drive signal to the phase control unit based on the operation signal and the arithmetic output, and the phase control unit controls the phase of the operation of the motor of the rubbing machine. Therefore, in the power supply period to the motor by the phase control, the motor is driven only during the vibration time with the pause time interval to vibrate the vibrator. As described above, since the vibration time and the vibration pause time of the vibrator are determined by the function calculation in the calculation unit based on the adjustment of the resistance value of the variable resistor, the vibration time of the vibrator according to the continuous change of the resistance value. The vibrator can be driven by continuously changing the time and the vibration pause time.

Only when the operation signal d of the timer 75 is given, the signal is supplied to the phase control section 31 through the AND gate 80.

The massaging apparatus having the above-described configuration is used, for example, with both feet placed on the upper surface while being placed on the floor, or with the waist or back placed. Then, for example, by placing both feet, the switch plate 4 is rotated around the leaf spring 6 and pressed down by its weight. As well as
The connection switch 22 is loosened and the start switch 21 is automatically closed. Further, when both feet are removed from the upper surface of the massager, the switch plate 5 is returned to the original position by the force of the leaf spring 6,
The start switch 21 is turned off, and the operation automatically stops.

When the start switch 21 is turned on, the power supply circuit 49 generates a direct current of +5 V, and the transistor 62 is turned on / off in the signal generation circuit 50 to which the rectified output a from the rectification stack 52 is supplied. ,
An operation signal b is formed and output. In this manner, the periodic signal generator 32 converts the operation signal b having the same cycle as the rectified waveform of the rectified output a from the rectifier stack 52 for converting the alternating current supplied from the commercial AC power supply into the direct current into the drive signal of the controller 34. It is supplied to the generator 79.

On the other hand, when the start switch 21 is closed, the massage operation is performed according to the time chart shown in FIG. In other words, A / D
It is determined whether the digital value of converter 33 has been input to operation unit 72. When the determination is NO, the determination is repeated until the determination becomes YES, and when the determination is YES, the function calculation in the calculation unit 72 shown in step 2 is executed.

In this calculation process, a digital value corresponding to an output voltage corresponding to the resistance value of the variable resistor 33 is calculated by a calculation formula ti =
f (V), t2 = g (V), t3 = h (V)
This is done by substituting into the part. The calculation formula ti = f
By the calculation in (V), the vibration time t1 of the vibrator 15 is determined,
The vibration pause time t2 during which the vibrator 15 stops is determined by the arithmetic expression t2 = g (V), and the vibration intensity variable time t3 in which the vibration intensity of the vibrator 15 changes by the arithmetic expression t3 = h (V). I can decide.

In step 3, both timers 75 for t1 and t3,
A trigger signal is given to 77, and these are started simultaneously. In the next step 4, it is determined whether or not the vibration intensity variable time t3 is zero. If the determination is NO,
Step 5 of gradually increasing the vibration intensity of the vibrator 15 by the processing in the drive signal supply unit 73 is performed.

In step 5, the vibration intensity control signal generator 78, which is operated in synchronization with the operation signal of the t3 timer 77, forms the control signal c and supplies it to the drive signal generator 79. Accordingly, a drive signal e corresponding to the control signal c is formed, and this signal e is transmitted to the t1 timer 75.
Is supplied to the phase control unit 31 through the AND gate 80 within the operation time of. As a result, the phase of the ignition output with respect to the operation signal b is changed.
The energization time of the motor B to the motor 14 is gradually increased, so that the vibration intensity of the vibrator 15 can be gradually increased.

In the next step 6, it is determined whether or not the time t3 set in the t3 timer 77 has elapsed. If this determination is NO, the process returns to step 5 and is repeated until the determination becomes YES. Then, the determination in step 6 is YE
When S is reached, step 7 for maintaining the vibration intensity of the vibrator 15 constant is executed. When step 7 is completed, the determination in step 8, that is, t1 set in the t1 timer 75 is performed.
It is determined whether or not a time T, which is obtained by subtracting the vibration strength gradually increasing time t3 from the time, has been reached. If this determination is NO, the process returns to step 7 and is repeated until the determination becomes YES.

If the determination in step 8 is YES, the process proceeds to step 9 where a trigger vibration is again applied to the t3 timer 77 to start the timer 77. Next, contrary to the gradual increase of the vibration intensity, a step of gradually reducing the vibration intensity of the vibrator 15 by gradually reducing the rotation of the motor 14 by the processing in the drive signal supply unit 73 for the time t3. 10 is executed. In the next step 11, t1, t3 timer 75,
It is determined whether the times t1 and t3 set in 77 have elapsed. If this determination is NO, the process returns to step 11 and is repeated until the determination becomes YES.

When the determination in step 11 becomes YES,
Since the time-up signal output from the t1 timer 75 is supplied to the t2 timer 76, step 12 in which the timer 76 starts is executed. By the execution of step 12, the driving of the motor 14 is stopped and the vibration of the vibrator 15 is stopped. In the next step 13, it is determined whether or not the time t2 set in the t2 timer 76 has elapsed. If this determination is NO, step 12
And the process is repeated until the determination becomes YES. And
If the determination in step 13 is YES, the t2 timer 76
The time-up signal output from the timer t1, t3 timer 75,
77 are supplied as trigger signals, respectively, and the process returns to step 1 and steps 1 to 13 are repeated again.

If the t3 time of the t3 timer is zero and the judgment in the step 4 becomes YES, the step 1 is executed.
1 is executed, and then steps 12 and 13 are executed one after another.
Steps 11 to 13 are repeated.

In the above operation, in the case of this embodiment, since the set time of the t3 timer 77 is zero as shown in FIG. 8 until the output voltage of the variable resistor 33 is 2 V, steps 1-4, 11- 13 is repeated and the masseters 12A, 12A
B is operated. Then, when the output voltage of the variable resistor 33 is adjusted to the minimum (1 V), the vibration of the vibrator 15 determined by the calculation using the calculation formula ti = f (1), as is clear from FIGS. The vibration pause time t2 at which the vibrator 15 stops determined by the time t1 and the calculation using the calculation formula t2 = g (1)
Are the minimum values, respectively, so that the motor 14 is driven only during the minimum vibration time t1 with an interval of the minimum vibration pause time t2 as shown in the vibration pattern of FIG. Therefore, the vibrator 15 can be vibrated sporadically.

When the output voltage of the variable resistor 33 is 2V
Is adjusted, the vibration time t1 of the vibrator 15 determined by the calculation using the calculation formula ti = f (2) and the calculation formula t2 = g
Since the vibration pause times t2 at which the vibrator 15 stops determined by the calculation in (2) become larger than the minimum values, respectively, FIG.
(C) As shown in the vibration pattern, at intervals of the maximum vibration pause time t2 longer than the minimum vibration pause time t2, only during the intermediate vibration time t1 longer than the minimum vibration time t1. The motor 14 is driven. for that reason,
The vibrator 15 can be intermittently vibrated.

Therefore, when the output voltage of the variable resistor 33 is adjusted between 1 V and 2 V, the vibration pattern shown in FIG. ) And the vibration pattern intermediate between the vibration patterns shown in FIG. 10 (C), the vibrator 15 can be intermittently vibrated.

When the output voltage of the variable resistor 33 is adjusted to 2 V or more, as is apparent from FIG.
Since the set time of 7 becomes larger than zero, steps 1-1
3 is repeated to operate the rubbing machines 12A and 12B. When the output voltage of the variable resistor 33 is adjusted to the maximum (3 V), the vibration time t1 of the vibrator 15 determined by the calculation using the calculation formula ti = f (3) and the calculation formula t2 = g (3 The vibration pause time t2 determined by the calculation in ()) and the calculation formula t3 = h
The vibration intensity variable time t3 of the vibrator 15 determined by the calculation in (3) is set to the maximum value. Therefore, FIG.
(E) Maximum vibration pause time as shown in the vibration pattern
The motor 14 is driven only during the maximum vibration time t1 with an interval of t2, and the vibrator 15 is driven in a vibration pattern in which the intensity of vibration gradually increases and decreases at the initial and final periods of the vibration time t1. Vibration can be intermittent.

When the output voltage of the variable resistor 33 is 2V
When the voltage is adjusted to between 3 V and 3 V, the vibration patterns shown in FIG. 10D, that is, the vibration patterns shown in FIGS. Can be obtained.

In the case of the vibration patterns shown in FIGS. 10 (D) and 10 (E), the vibration intensity gradually increases and decreases at the beginning and the end of the vibration period t1 even though the vibration time t1 is long. Therefore, the contact with the massaged part starts softly and ends softly, and there is no inconvenience that stimulation to the massaged part is too strong.

The present invention is not limited to the above embodiment. For example, at the beginning and end of the vibration time t1, the t3 timer 77 for gradually increasing and decreasing the vibration intensity and the vibration intensity control signal generator 78 may be omitted.
