DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vibration recorder for recording, for example, a vibration generated by a movement such as a walking motion of a pedestrian over time.

[0002]

2. Description of the Related Art A so-called pedometer has been conventionally known as an instrument for measuring the amount of exercise of a pedestrian, for example. However, a pedometer mainly measures and displays the number of steps taken by a pedestrian.In some cases, the approximate walking distance can be displayed by multiplying the number of steps by a stride. There was a problem that the situation could not be recorded.

[0003]

SUMMARY OF THE INVENTION The present invention has been proposed in view of the above problems, and has as its object to provide a vibration recorder which can easily record the chronological state of a pedestrian or the like over time. With the goal.

[0004]

In order to achieve the above object, a vibration recorder according to the present invention has the following arrangement.

That is, the pendulum is oscillated by the vibration generated by the movement of the pedestrian when the pendant is attached to the body or the like of the pedestrian, and the recording hand is moved by the oscillation of the pendulum. The method is characterized in that vibrations are recorded on a recording paper to be processed.

When the vibration recorder constructed as described above is mounted on a pedestrian's body or the like, the pendulum swings due to the vibration generated by the movement of the body or the like, and the recording needle moves by the swing of the pendulum. The vibration is recorded on the recording paper. By looking at the record of the vibration, it is possible to grasp the exercise status over time, and by summing up the records as appropriate, it is possible to know the overall exercise time, the exercise time for each predetermined time zone, and the like. .

The pendulum 20 is rotated counterclockwise in FIG. 5A beyond the swing range by the rotation operation pin 30b of the guide lever 30, and the recording needle 15 moves outside the normal recording width W. After that, the recording needle 15 is moved by the spring plate 50 to the recording paper P.
The point mark M can be attached to the outside of the normal recording width W as shown in FIG.

The above-mentioned operation of attaching the point mark M can be performed while the body of a pedestrian or the like is operating, that is, even when the pendulum 20 is swinging. 40 is returned to the original position by the leaf spring 42, the guide lever 30 and the spring plate 50 also return to the original state, and the vibration recording by the recording needle 15 is resumed.

In the illustrated example, the point mark M is provided outside the normal recording width W. However, the point mark M may be provided inside. In the above embodiment, the point mark M is provided by pressing the operation button 41. However, the point mark M may be provided by rotating or pulling the operation button.

By using the pendulum 20 configured as described above in place of the pendulum 20 of the second embodiment, when the pendulum 20 swings in the left-right direction as in the second embodiment, the recording paper is moved by the recording needle 15. The vibration can be recorded on the recording paper P by the vibration in the vertical direction while the vibration can be recorded on the recording paper P.

That is, when the pendulum 20 swings in the left-right direction, the swing arm and the ratchet 23 reciprocately rotate about the main shaft 12 together with the pendulum 20, thereby causing the ratchet 23 to move through the pin 16 c. Recording needle holder 16 to be engaged
Reciprocates around the support shaft 61, and the vibration is recorded on the recording paper P by the recording needle 15 on the holder 16. on the other hand,
When a vertical vibration acts on the pendulum 20, the pendulum 2
The zero weight 22 swings up and down around the support shaft 22d, whereby the ratchet wheel 23 reciprocates around the bearing member 21c via the fork 22f and the rotation operation pin 23f. In this embodiment, the rotation amount is the ratchet wheel 2
The third claw 23a is about one pitch (one mountain). The reciprocating rotation of the ratchet wheel 23 causes the ratchet wheel 23 and the pin 1 to move.
The recording needle holder 16 engaged via the reference numeral 6c reciprocates around the support shaft 61, and vibration is recorded on the recording paper P by the recording needle 15 on the holder 16.

As described above, in the present embodiment, in addition to the vibration in the horizontal direction, the vibration in the vertical direction (vertical direction) can be detected and the recording can be performed on the recording paper. Also in this embodiment, the usable inclination angle θ of the vibration recorder can be made large as in the second embodiment. Although not shown in the drawings, the second and third embodiments can be provided with a mechanism for attaching the same point mark as in the first embodiment.

[0053]

As described above, according to the vibration recorder according to the present invention, for example, when a person wears his / her waist or the like and carries it, the movement of the person as a vibration trajectory on the recording paper rotated by the clock mechanism. Since the recording can be performed, it is possible to easily analyze the movement corresponding to the time, total the operation time, and the like. Further, if a function of attaching a point mark on the recording paper is provided, a point mark serving as a mark can be attached to the recording paper P at the start of recording or at the break of the operation during recording, or at any other time. There is an effect that it becomes possible to easily perform analysis, aggregation, and the like.
