Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information storage module capable of reading various kinds of stored information from the outside in a non-contact state, and an article provided with the information storage module and the information storage element, for example, entry control in a food processing factory. Shoes, and cables, water pipes buried in the ground,
The present invention relates to a pile used for indicating the state of burial of a gas pipe or the like, the position of a land or a road, the boundary of a land, a survey point, and the like.

[0002]

2. Description of the Related Art Conventionally, in order to manage information on a pile, an information storage element storing various types of information has been built in the head of the pile. The information storage element includes an information storage circuit and a coil-shaped antenna that transmits information stored in the storage unit in response to an external electromagnetic wave, and these are housed in a protective case made of resin. . However, when such an information storage element is incorporated in a pile and used, if an external impact load is applied, the internal information storage circuit and the like may be damaged.

[0003] In addition, containers such as gas cylinders are provided with an identification number or a bar code on the outer wall of the container which indicates the date of manufacture, manufacturer, capacity, inspection date, sales record, etc.
These are used to control the contents of the container. However, with the identification numbers and barcodes, not only the amount of information that can be managed is small, but also the information is peeled, dirty, or damaged during use, so that accurate management is difficult. Therefore, the information storage element is attached to the outer wall of the container by bonding,
It is conceivable to manage the contents. Since this information storage element can store a large amount of information, it is possible to manage contents in detail. However, a container such as a gas cylinder has a curved wall, and the protective case of the element cannot be adhered along the curved wall. It is difficult to firmly attach the element to the container wall. further,
Even when the element is hung by a string or chain and attached to a container, the element is dropped by cutting the string or chain with long-term use, or by repeatedly performing collision between the element and the container wall surface, The case cracks,
The internal information storage circuit may be damaged.

Accordingly, a first object of the present invention is to provide an information storage module which has excellent shock resistance and does not damage an information storage element even when subjected to an impact load. A second object is to provide an article such as shoes using the information storage module and the information storage element.

[0005]

In order to achieve the first object, an information storage module according to a first aspect of the present invention includes an information storage circuit having a storage unit for storing information, and an information storage circuit receiving an external electromagnetic wave. An information storage element including an antenna for transmitting information stored in the unit is covered with a cover made of an electrically insulating elastic material.

When the information storage module receives an external impact load due to vibration, collision with an object, or the like, the impact load is absorbed and alleviated by the elastic deformation of the cover covering the entire information storage element. Therefore, the shock resistance is excellent, and the damage of the information storage element due to the shock load is reliably prevented. Furthermore, the coating made of an elastic material can be easily and reliably bonded while securing a sufficient bonding area while being elastically deformed along the curved wall of a container such as a gas cylinder. An information storage element for object information management is firmly attached to the wall of the container. When a force is applied to the information storage module to peel it off, a part of this force is absorbed by the elastic deformation of the cover, and is applied to the adhesive surface between the cover and the container wall. The resulting peeling force is reduced. This prevents the information storage module from falling off the container wall. For this reason, detailed management of the contents of the container using the information storage element is possible. further,
The information storage module can read various kinds of information stored in the information storage element in a non-contact state. That is, a detector is brought closer to the information storage module, an electromagnetic wave to be generated is input to the information storage element, and various information stored in an information storage circuit of the element is transmitted from an antenna, and this information is transmitted to the detector. Since the data can be read by receiving the data by a receiver built in the device and displaying the data on a display device, information management can be easily performed.

In a preferred embodiment of the present invention, the information storage element has a protective case for housing an information storage circuit and an antenna. According to this configuration, since the information storage element is protected by the protective case and the covering, damage to the information storage element due to an impact load is more reliably prevented.

[0008] In another preferred embodiment of the present invention, the information storage circuit is formed in a thin film shape having a circuit pattern formed on a circuit board, and the front and back of the information storage circuit are covered with protective films. Also according to this configuration, the information storage circuit is protected by the protective film provided on the front and back of the information storage circuit and the cover, so that the information storage circuit is more reliably prevented from being damaged by an impact load.

In order to achieve the first and second objects, a second invention mounts the information storage element on a shoe, and a third invention mounts the information storage module on a shoe. .

According to the second and third inventions, for example, when a worker wearing shoes moves between rooms in a food processing factory or the like and performs various operations, the information attached to the shoes is Based on the information transmitted from the storage element or the information storage module, it is possible to manage the entry / exit of the worker, as well as the work position and the work speed.

In the preferred embodiments of the second and third aspects of the present invention, the information storage element or the information storage module is fitted into a recess provided on an upper surface of a shoe sole. According to this configuration, by fitting the information storage element or the information storage module into the recess of the shoe sole, damage due to collision of the element or the module with an object or the like is effectively prevented.

In order to achieve the first and second objects, a shoe according to a fourth aspect of the present invention provides an information storage element in which an information storage circuit and an antenna are housed in a protective case in a recess provided on an upper surface of a shoe sole. And a cushion material that is in contact with the upper surface of the information storage element, and the inner sole is joined to the upper surface of the shoe sole in a state where the cushion material is compressed.

According to this shoe, although the information storage element is fitted alone into the recess of the shoe sole without providing the cover, the information storage element is formed by the cushion material fitted in the recess in a compressed state. And the information storage element is reliably prevented from being damaged due to vibration when walking or collision with an object. Further, the position of the information storage element is regulated by the cushion material, so that the information storage element does not move unexpectedly.

In order to achieve the first and second objects, a fifth invention is a pile driven into the ground, wherein the information storage module is incorporated.

According to this pile, since the information storage module in which the information storage element is covered with the covering member is provided inside the pile, even when the pile receives an impact load when driven into the ground, The cover ensures that the information storage element is protected. Therefore, the buried information such as cables, water pipes, and gas pipes stored in the information storage element, and the information such as the position of the land or road, the boundary of the land, and the survey points can be reliably obtained.

In order to achieve the first and second objects, a sixth invention relates to a pile driven into the ground, wherein the information storage element in which an information storage circuit and an antenna are housed in a protective case is provided. The information storage element is housed in a storage room formed therein, and the outer peripheral portion of the information storage element is supported by the wall surface of the storage room via a support member made of an elastic material, and is stored with other parts except the outer peripheral portion of the information storage element. Upper and lower air layers are provided between the upper and lower surfaces of the chamber.

According to this pile, when an impact load is applied from the outside when the pile is driven into the ground, the support member supporting the information storage element reciprocates between the upper air layer and the lower air layer in the storage room. Since the impact load is absorbed and alleviated, the impact load applied to the information storage element is reduced, and damage to the information storage element due to the impact load is prevented.

In a preferred embodiment of the sixth invention,
A communication passage communicating the upper air layer and the lower air layer is provided through the support member. According to this configuration, even when a large impact load at the time of driving is received from the upper portion of the pile, damage to the information storage element is effectively prevented. That is, when an impact load is received from the upper part of the pile, the information storage element tends to vigorously move upward and downward due to the inertial force. However, when the information storage element moves upward to compress the upper air layer, the air therein is sent from the communication passage to the lower air layer, and the information storage element moves downward to compress the lower air layer. At this time, the air inside is sent from the communication passage to the upper air layer, so that both air layers alternately exert a large buffering force. For this reason, the severe vertical movement of the information storage element is suppressed, and damage to the information storage element is effectively prevented.
