  In the case of the above background art, since the IC tag is provided with a plate-like circuit board, it is formed on a flat plate. For this reason, the IC tag is difficult to attach to a helmet formed in a semicircular shape. Therefore, when the IC tag is attached to the inner surface of the helmet, an IC chip or other circuit is formed on the flexible substrate and is provided integrally with the helmet. In the case where the IC tag is incorporated in accordance with the curve of the helmet, it has to be formed integrally from the time of helmet production, which is costly. In addition, since the IC tag is fixed integrally with the helmet and is not detachable, a normal name tag or other ID card cannot be used as a helmet IC tag. Tags had to be used and were expensive.

On the surface of the sheet 62 opposite to the main body 12, a printing unit 64 such as an operator's name is provided. The sheet 62 may have a waterproof function.

  Next, a method for assembling the helmet tag 10 will be described. The circuit board 40 is placed in the circuit board housing portion 16 b of the housing portion 16 of the main body 12, the housing portion cover 50 is fitted into the housing portion 16, the hole portion 54 of the housing portion cover 50, and the through hole 41 of the circuit board 40. Then, the female screw portion 13 of the main body 12 is matched, and the screw 56 is inserted from the outside of the housing portion cover 50 and screwed to be fixed. The battery 22 is inserted into the battery housing portion 16a of the housing portion 16 of the main body 12 from the side surface 12b and fitted into the battery through hole 15, and then the battery cover 24 is fitted into the battery through hole 15 so that the battery cover is covered. 24 holes 26, the holes 17 of the main body 12, and the female screw portions 52 of the housing cover 50 are aligned with each other, and screws 28 are inserted from the outside of the battery cover 24 to be screwed and fixed. Moreover, the hole 58 of the accommodating part cover 50 corresponds to the female screw part (not shown) of the accommodating part 16, and the screw 60 is inserted from the outside of the accommodating part cover 50 to be screwed and fixed. A protective sheet 38 is attached to the battery housing portion 16 a of the housing portion 16 so as to cover the battery cover 24. The switch cover 30 is attached to the circuit board housing 16b. A sheet 62 is attached to the side surface 12 a of the main body 12 so as to cover the circuit board 40. The sheet 62 may be attached with a double-sided tape or the like.

  Next, the usage method of the helmet tag 10 is demonstrated based on FIG. 6, FIG. A storage portion 68 having an inner pocket shape or the like is formed in a lateral portion of the helmet 66. The accommodating portion 68 has a curved shape along the curved surface in the circumferential direction of the helmet 66. The helmet tag 10 is placed in the housing portion 68 of the helmet 66 provided with the housing portion 68. At this time, the side face 12b of the main body 12 of the helmet tag 10 is set to face the head side, and the helmet tag 10 is set in a direction that becomes horizontal when the helmet 66 is worn. Thereby, the flexible antenna portion 14 provided in the same portion as the main body 12 is curved along a horizontal arc shape that is a curve having a large curvature radius of the helmet 66.

  On the other hand, the housing portion 16 in which the circuit board 40 made of a hard synthetic resin or the like is housed is positioned with the narrower width at the center of the helmet tag 10 in the horizontal direction. The helmet 66 is worn in a flat state with little bending in the direction.

  Thereafter, when the worker 70 wears the helmet 66 with the helmet tag 10 attached thereto and turns on the switch 44, the helmet tag 10 is received by an IC chip attached to the circuit board 40 and a signal transmitted and received by the antenna unit 14. It is possible to manage entrance / exit of a specific person at a predetermined place and confirm the position. In addition, it is possible to confirm whether the helmet 66 is worn by the operator 70 by a sensor attached to the circuit board 40.

  According to the helmet tag 10 of this embodiment, it can be used also as a name tag or an ID card, and can be easily attached to the helmet 66 and put on the worker 70 to reliably manage the entry / exit of the worker 70 and the position. Can be confirmed. Since the main body 12 has flexibility, the helmet tag 10 can be easily bent and attached along the shape of the helmet, and the wearing feeling is also good.

  In particular, the helmet tag 10 can be easily bent by matching the longitudinal direction of the main body 12, that is, the antenna portion 14, in the horizontal direction where the radius of curvature of the helmet 66 cannot be increased, and the curvature radius of the helmet 66 is compared. An accommodating portion 16 is provided in the vertical direction of the side surface, which is a portion that can be enlarged, and the circuit board 40 that is difficult to bend is disposed in the vertical direction and accommodated. Furthermore, in the assembly of the helmet tag 10, since the portion between the screws 28, 56, and 60 fixed is difficult to bend, the screws 28, 56, and 60 are arranged in the vertical direction so as not to be bent, and are provided in the housing portion 16. It does not interfere with the curvature. Further, the battery 16 is accommodated in the accommodating portion 16, and no force is applied to the battery 22 in the bending direction, so that there is no risk of disconnection or damage. Since the helmet tag 10 is provided with a human sensor or a temperature sensor, it is possible to confirm whether the helmet 66 is worn by the operator 70, and by controlling so that the battery operates only when worn, Battery life can be extended.

  Furthermore, the helmet tag 10 can be detached because it is only put in the housing portion 68 of the helmet 66, and when the helmet 66 is not worn, the helmet tag 10 can be removed and attached to clothes or used by being lowered from the neck with a strap. It is convenient because it can be used as an ID card. Since the main body 12 is made of a flexible synthetic resin, the helmet tag 10 is less likely to be damaged even when subjected to an impact such as a drop of the helmet 66.

  In addition, the helmet tag of this invention is not limited to the said embodiment, The form of each member can be changed freely and the accommodating part should just be provided long in the predetermined direction, and a battery and a circuit The arrangement and the like of the substrate can be freely changed.
