Abstract

PROBLEM TO BE SOLVED: To provide a mobile object information identifying device which can be quickly realized without changing the structure of any primary part such as a control board at the time of making an incorporated antenna larger than a case. SOLUTION: At the time of changing an antenna 4 from a 4 patch antenna 14 to a 16 patch antenna 114 whose size is larger than the size of the 4 patch antenna 14, a metallic chassis 113 holding the 16 patch antenna 114 is made large, and the size of an upper case 110 is made large so that the large 16 patch antenna 114 and the metallic chassis 113 holding the 16 patch antenna 114 can be housed. Thus, it is possible to realize a mobile object information identifying device 102 without changing any other control board 24 or heat radiator 26 or the like, or changing the mounting position or mounting structure of an upper case mounting part 11 or a lower case mounting part 21.

2. Description of the Related Art This kind of conventional mobile object information identification device is
The power is transmitted wirelessly to a mobile identification card (which does not hold a power source) in a non-contact manner, and the mobile identification card is operated with the power. In this case, in the conventional mobile object information identification device, when the internal components such as the antenna must be larger than the case, the case and the built-in control board are also changed.

[0003]

In the above-mentioned conventional mobile object information identification device, it is necessary to make a change such as making the size and shape of the built-in antenna (patch antenna) larger than the case. However, in this case, there is a problem that the development period is prolonged and the cost is increased because not only the case but also the built-in control board must be changed.

The present invention has been made in order to solve the above problems, and even if a change such as making the size and shape of the built-in antenna larger than that of the case arises, It is an object of the present invention to provide a mobile object information identification device that can be realized in a short time without changing the structure of a main part such as a control board.

[0005]

According to the present invention, an upper case and a lower case constitute a case, in which a patch antenna and an electronic component mounted on a metal chassis are mounted. In the moving object information identification device containing the control board, a plurality of upper case mounting portions provided to vertically protrude from the inner surface of the upper case and the upper case are provided so as to protrude vertically from the inner surface of the lower case. A plurality of lower case mounting portions provided so as to face the plurality of mounting portions, wherein a plurality of upper cases capable of sandwiching the metal chassis therebetween so that the metal chassis is held in the upper case. A case mounting part and a plurality of lower case mounting parts, and a plurality of upper case mounting parts and a plurality of lower case mounting parts sandwiching a metal chassis therebetween. A case coupling member for removably coupled, so that the control board is disposed on the lower side of the metal chassis, a control board mounting means for mounting the control board to the metal chassis.

According to such a configuration, the size of the upper case is adapted only to the size of the metal chassis and the size of the patch antenna mounted on the metal chassis. The present invention can be realized in a mobile object information identification device irrespective of components to be arranged.

In the embodiment of the present invention, when the antenna is changed from the four patch antenna 14 to the large 16 patch antenna 114, the metal chassis 113 holding the 16 patch antenna 114 is enlarged,
In order to accommodate the enlarged 16 patch antenna 114 and the metal chassis 113 holding it, the upper case is simply enlarged like the upper case 110 without changing the other control board 24, the heat radiating plate 26, etc. The mobile object information identification device can be realized without changing the mounting position, the mounting structure, and the like of the upper case mounting portion 11 and the lower case mounting portion 21.

In the present invention, when the metal chassis and the patch antenna have a size extending horizontally to the outside of the lower case, the outer shape of the upper case in the horizontal direction is not changed without changing the position and shape of the upper case mounting portion. Only increase.

With this configuration, even when the metal chassis and the patch antenna case mounted on the metal chassis must be larger than the case, the increased metal chassis and the patch antenna mounted on the metal chassis can be accommodated. In addition, by increasing the size of the upper case, it is possible to realize a mobile object information identification device without changing other components and mounting structures.

In the embodiment of the present invention, the metal chassis and the antenna are connected to metal chassis 113 and 1.
Even if it becomes large like a six-patch antenna 114, the mobile body information identification device can be realized by extending the outer edge of the upper chassis outward to form a shape like the upper case 110.
