  Hereinafter, the best mode of the present invention will be described with reference to the drawings. However, such examples do not limit the technical scope of the present invention.

    1 and 2 show an example of a pressure sensor used in the present invention. The top view and sectional drawing of the disk-type flexible multistage switch which can be turned ON / OFF to 3 steps are shown. The pushing surface part of the disk type flexible multistage switch is composed of the first layer flexible plate 1 and the bottom part of the fourth layer flexible plate 4, and the first layer flexible plate 1 and the fourth layer flexible plate 4 It is crimped to achieve both disk-shaped structure space and waterproofness.

  FIG. 3 is a right top view of the foot pressure sensing (sensing) insole according to the first embodiment of the present invention, and the left view is omitted in a symmetrical configuration.

  The stepping pressure sensor 1 (a, b, c, d) is disposed on the heel, toe and thumb, and the foot pressure center locus is calculated based on the degree of ON / OFF stepping pressure.

  The fingertip sensing (sensing) point movable area 10 and the toe sensing (sensing) point movable area 20 are telescopic, position the treading pressure sensor b and the treading pressure sensor c on the toe region intended by the user, and similarly tread on The pressure sensor a is also fixed to the center of the thumb ball.

  In the case of using the disk type multistage switch which converts the pressure degree to ON / OFF binary signal according to the treading pressure of the inventor when the ball is fitted to the thumb ball, the treading is performed when the switch center deviates from the thumb ball center Since the degree of pressure is also detected in a shifted manner, a gel specification that does not shift the center of the thumb in a bowl-shaped footwear sheet shape is optimal.

  The footwear sheet 5 is a good member per foot, and the diameter of the treading pressure sensor is 18 mm, the thickness is 0.9 mm in one step, 1.5 mm in three steps in an experimental example, the thickness of the footwear sheet is also about 1.5 mm The step of the treading pressure sensors a, b, c, d and the footwear sheet 5 is eliminated by using a member of the above-mentioned member to open roundly so that the treading pressure sensor can be fitted, and the fit feeling is good.

  Although the flexible printed wiring board (FPC) signal output connector cord 6 is put out at the foot of the footwear, it is smooth when worn around the foot of the footwear as shown in FIG.

  The attachment position of the bellows cord storage groove is the FPC signal output connector outlet adjustment where the foot pressure does not act as much as possible between the heel and arch and the FPC bellows toe adjustment storage groove 3 is the outer center position of the arch and the FPC bellows leg. In the finger adjustment storage groove 2, it is desirable to attach in the middle between the finger and the outer edge of the toe, and in particular when using it inserted into a sock, since thickness is restricted, attaching using the shape of the sole is optimal is there.

  It is desirable that the width of the FPC signal circuit 7 be as small as possible, and it is desirable to print an electric circuit, so that it can be configured to be bellows-folded or freely bent as shown by the FPC slide folding signal circuit 40 in FIG.

  However, a drawback of the conductive printed wiring is that if the printed inner side is bent inside, the print is not easily peeled off but the outer side is easily peeled off since it is bent outward, and therefore, it is necessary to bend the curve gently.

  In order to prevent the print peeling, in the example shown in FIG. 8, it is possible to make the stress at the time of expansion and contraction of the FPC by the expandable filling member 71 uniform and prevent the print peeling.
