Input to the CPU 9 via the / D converter 10 is similar to the configuration of the grip portion 2 described above (see FIG. 3).
In FIG. 1, only the pressure-sensitive element 8 is shown for convenience of illustration, but in reality, the grip portions 2 and 20 are provided with different input paths. )

Three types of switches SW0 to SW2 are provided on the front side of the upper surface of the equipment outer box 3. These switches are a reset switch SW0, a reference value setting switch SW1 and a volume switch SW2 in order (the operation of each switch will be described later). Also,
On the right side of the device outer box 3, two types of switches SW3, S
W4 and the speaker 11 are provided. SW3 is a sampling cycle setting switch composed of a DIP switch, and SW4 is a power switch of the grip strength training device 1. A staff 15 is drawn on the upper surface of the outer box 3 of the device. In this staff 15, LEDs 14A to 14H (are located at positions corresponding to one octave from "low do" to "high do" in order from the left. (Corresponding to the “light emitting device” of the present invention) is mounted.

Next, the hardware configuration of the grip training device 1 will be described with reference to FIG. 4 (note that by inputting the power switch SW4, various devices (CPU
(9, amplifier 12, etc.), but for convenience of illustration, a part of the electrical configuration is not shown in FIG. 4). The device outer box 3 is provided with a CPU 9 that processes various signals according to an algorithm described later. The pressure sensitive element 8 is connected to the CPU 9 via an A / D converter 10 that converts an analog signal into a digital signal. In addition, the CPU 9 has a power supply unit 1
The vibrator 4 is connected via 6 and the CPU 9
The vibrator 9 can be vibrated by a signal from. Furthermore, signals from the above-mentioned four types of switches SW0 to SW3 are input to the CPU 9.

A speaker 11 is connected to the CPU 9 via an amplifier 12, and a sound belonging to a predetermined scale can be generated by the sound signal Sso.
Further, the CPU 9 is connected with a plurality of light emitting elements 14A to 14H that emit light according to the lighting signal Sph. Each of the light emitting elements 14A to 14H emits light according to the type of the lighting signal Sph output corresponding to the sound signal Sso. In the present embodiment, all the light emitting elements 14A to 14 corresponding to the sound lower than the sound specified by the sound signal Sso.
H is set to emit light. For example, the sound signal S
When so is set to output the sound of “so”, the lighting signal Sph is “low” in the staff 15.
14A to 14A at positions corresponding to
All E's are designed to emit light.

Next, referring to FIGS. 5 to 8, the CPU 9
The algorithm of the program executed by will be described. When the power switch SW4 is turned on, the CPU 9 initializes various variables (step 10). That is, the sampling period T0, the reference pressure P0, and the minimum pressure PL are set to preset initial values. Here, the sampling cycle T0 is an interval for reading the pressure signal Spr from the pressure sensitive element 8 and is set to 0.5 seconds. Further, the minimum pressure PL is a numerical value set in order to restrict the output of sound from the speaker 11 when the pressure is not applied to the pressure sensitive element 8, and is set to 5 kg / m ² . . The reference pressure P0 is a reference value of the pressure for causing the speaker 11 to output a "high-pitched" sound, and is 45 kg / m.
It is said to be ² .

Next, it is judged whether or not the reference value setting switch SW1 is operated (step 20), and if it is operated, the reference value setting routine shown in FIG. 8 is executed (note that in FIG. The flow of 8 will be described later). When the reference value setting switch SW1 is not operated in step 20, the process proceeds to the next step 30. In step 30, after waiting for the sampling period T0 to elapse,
Go to step 40. In step 40, the values of the sound signal data A1 to A3 are exchanged. Here, the sound signal data A
1 to A3 are for causing the speaker 11 to output a sound corresponding to the sound determination section to which the value of the pressure signal Spr belongs. More specifically, the sound signal data A1 to A3 itself is one of integer values of 1 to 8, for example, and the CPU 9 sets the sound corresponding to the sound signal data A1 as the sound signal Sso. When outputting to the amplifier 12, the sound is converted into an appropriate digital wave. In this embodiment, a new pressure signal Spr is read and a predetermined process is performed every time the sampling period T0 elapses. Therefore, before taking in the new pressure signal data Spr, the order of the sound signal data A1 to A3 is advanced. That is, the sound signal data A2 of the previous two times is set to A3, and the sound signal data A1 of the previous time is set to A2. Then, in step 50, the pressure signal Spr output from the pressure sensitive element 8 is read.

In the next step 60, the sound signal data A1 is set from the value of the pressure signal Spr based on the sound signal setting routine shown in FIG. Here, FIG. 6 and FIG.
The procedure for setting the sound signal data A1 will be described with reference to FIG. An initial value or a value obtained by subtracting the minimum pressure PL from the reference pressure P0 set in step 20 (in this embodiment, P0-PL = 40) is divided into eight equal parts and is set as a partitioning variable B. Then, the pressure value obtained by sequentially adding the partitioning variable B to the lowest pressure PL is partitioned as a sound determination partition. In this way, the first sound determination section (P
L to PL + B), the second sound determination section (PL + B to PL +
2B), the third sound determination section (PL + 2B to PL + 3B)
Are divided, and up to the eighth sound determination section (PL + 7B-) is determined. Next, the sounds of "low do", "re", and "mi" are assigned in order from the first sound determination section, and "high" is assigned to the eighth sound determination section.

Next, it is determined in steps 71 to 77 which sound determination section the pressure signal Spr belongs to, and the sound corresponding to the selected sound determination section ("low"-
“High” is set in the sound signal data A1 (step 71-2 to step 78-2). Next, step 7
At 0, the lighting signal Sph corresponding to the sound signal data A1 is output to the light emitting elements 14A to 14H, and the lighting signal Sp is output.
The LEDs 14A to 14H corresponding to h are turned on. In the present embodiment, since all the LEDs 14A to 14H corresponding to sounds lower than the sound determined by the sound signal data A1 are set to emit light, the light emitting elements 14A to 14H.
H plays the role of a kind of grip force meter. In addition to this, as a lighting method of the light emitting elements 14A to 14H, an LED corresponding to only the sound emitted by the sound signal data A1
Although it may be possible to turn on only 14A to 14H,
Compared with such a method, the lighting method of the present embodiment has a larger visual effect.

Next, in step 80, the sound signal data A
The condition that all of 1 to A3 are equal is determined. Here, when the sound signal data A1 to A3 are all the same, the sound signal data A1 is sent to the amplifier 12 as the sound signal Sso.
And a predetermined sound is output from the speaker 11 (step 90). On the other hand, when the above conditions are not satisfied, the sound signal Sso for stopping the speaker 11 is output to the amplifier 12 (step 100). As described above, in order to output a certain sound from the speaker 11, it is necessary to exert the same degree of gripping force over the interval of two or more sections of the sampling cycle T0. As a result, the operator of the grip strength training device 1 makes an effort to output a desired sound quickly, or makes an effort to play music by eliminating the output of useless sound, so that the training effect is improved. .

Next, the procedure for setting the reference pressure P0 will be described with reference to FIG. Since the grip strength training device 1 of the present embodiment is designed in consideration of not only the grip strength training of a healthy person but also the rehabilitation of an elderly person or a sick person, the training can be performed according to the grip strength of each user. desirable. Therefore, the sound determination section can be set according to the grip strength of the user. To set the reference pressure P0, the grip portion 2 or 20 is gripped as strongly as possible while the reference value setting switch SW1 is pressed (step 20). At this time, out of the eight LEDs
“Low” 14A, “Fa” 14D, “So” 14E,
The lighting signal Sph is outputted so that four "high" 14H lights up (step 21), indicating that the reference value is being set. In this state, when the sampling cycle T0 has elapsed (step 22), the pressure signal Spr fetched at that time is set to the reference pressure P0 (step 24).

Next, the reference pressure P0 is compared with a predetermined value (30 kg / m ^{2 in the} present embodiment) (step 26). If it is smaller than that value, the minimum pressure PL is 2 kg. / M ² is set (step 28). Further, by operating the switch SW3 including the DIP switch, the sampling period T0 of the pressure signal Spr input from the pressure sensitive element 8 to the CPU 9 can be set. Therefore, for example, it is considered that a person with a strong grip strength can change the grip strength quickly. Therefore, while the sampling cycle T0 is set to be short (the interval for capturing the pressure signal Spr is set to be small), a person with a weak grip strength can grasp the grip strength. Since it is considered that it takes a long time to change, it is possible to set the sampling cycle T0 to be long (to set the capturing interval of the pressure signal Spr to be large).

By operating the reset switch SW0, it is possible to return to the initial setting stage (step 10). Thus, according to the present embodiment, the grips 2, 2
A sound belonging to a certain scale is output from the speaker 11 in accordance with the pressure applied when 0 is gripped, which can be a motivation for training when performing work such as rehabilitation, and can be performed while maintaining interest. .

Further, the reference pressure P0 for calculating the fluctuation range of the pressure signal Sph is determined based on the value of the pressure signal when the reference value setting switch SW1 is operated.
Since the section according to the grip strength of the operator of the grip strength training device 1 is set, the grip strength training can be performed without difficulty. Furthermore, since the sound is output from the speaker 11 only when the sound signal data A1 to A3 are equal, it is possible to perform training so that only the desired sound is output. This also allows for playing music, which can be a goal for training. In addition, since light is emitted from the LEDs 14A to 14H according to the sound output from the speaker 11,
Not only hearing but also sight is stimulated, and you can train more interestingly.

The technical scope of the present invention is not limited to the above-described embodiment, and the following technical scope is also included in the technical scope of the present invention.
In addition, the technical scope of the present invention extends to an equivalent range. (1) In the present embodiment, the sound output from the speaker 11 is set to increase in order of increasing pressure applied to the grips 2 and 20, but according to the present invention, the sound is added to the grips. You may set so that a low sound may be output as pressure increases. (2) In the present embodiment, when a predetermined pressing force is applied to the grip portions 2 and 20, sound is output from the speaker 11, but according to the present invention, a muffling switch is provided. The sound from the sound output unit may be muted. Also, a headphone terminal or the like may be provided. (3) In the present embodiment, the grip force applied while operating the reference value setting switch SW1 serves as a reference for determining the maximum value of the sound determination section. However, according to the present invention, for example, the reference value setting switch is The grip force applied during operation may be set so as to determine a section that is about half the maximum value of the sound determination section (for example, the sound of "so"). (4) In the present embodiment, the LEDs 14A to 14H are the LEDs corresponding to low sound from the LED at the position corresponding to a certain sound.
However, according to the present invention, only the light emitting element at a position corresponding to a certain sound may be caused to emit light.
