Abstract

PURPOSE:To certainly prevent damage due to external force and to make long- term use possible by arranging an electronic part in the vicinity of the inside peripheral part of the frame member provided to the outer peripheral edges of two outer panels between them or providing a support member in the vicinity of the circumference of the electronic part. CONSTITUTION:A multifunctional IC card 1 is constituted by receiving a printed circuit board 6, a liquid crystal display device 7, a battery 8 and a quartz vibrator 9 being an electronic part in a plate-shaped housing 5 consisting of front and back panels 2, 3 being two outer panels and a guard frame 4 being a rectangular frame member. The vicinal part of the guard frame 4 has high rigidity and generates almost no deformation even when external force F is applied to said part and, therefore, no pressure is applied to the quartz vibrator 9 thinner than the guard frame 4 arranged to corner parts to prevent the damage of said vibrator 9. The quartz vibrator 9 may be surrounded by a rectangular frame-shaped metal support member 10 thicker than the quartz vibrator 9.

Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a thin electronic device such as a multi-functional IC card, and more specifically, it relates to a thin electronic device such as a multi-function IC card, and more specifically, a device consisting of two outer panels and a frame member. The present invention relates to a thin electronic device in which electronic components are housed in a plate-like housing.

(Prior Art) In recent years, multifunctional IC cards have been increasingly used as information processing media.

As shown in Fig. 6, this multifunctional IC card consists of two outer panels: a front panel a and a back panel b.
1 and a guard frame C as a rectangular frame member, several electronic components f including a printed circuit board e and a crystal resonator f... (only one is shown)
It is configured to house.

However, in conventional thin electronic devices of this type, the electronic components f... are not arranged in consideration of the influence of external forces, and the components such as crystal oscillators, which are relatively weak against circumferential pressure, The electronic component f was also placed approximately in the center of the plate-like housing d. Therefore, as shown in Fig. 6, if an external force is applied to the plate-shaped housing d for some reason and the outer panels, such as the front panel a and the back panel b, are bent or dented, the electronic components f... Direct pressure is applied, and electronic components f such as crystal oscillators, which are relatively weak against circumferential pressure, may be damaged.

(Problems to be Solved by the Invention) As described above, in the past, if the front panel or back panel, which is the outer panel of a plate-shaped housing, is bent or dented for some reason, it is difficult to accommodate the front panel or back panel in the plate-shaped housing. In some cases, direct pressure was applied to the electronic components being used, causing damage to the electronic components and making it impossible to maintain the performance of the electronic device.

This invention was made based on the above circumstances, and its purpose is to have a simple structure, yet to reliably prevent damage to electronic components housed in a plate-like housing due to external forces, and to provide long-term use. The aim is to provide a thin electronic device that can be used with ease.

[Structure of the Invention] (Means for Solving Issue M) In order to solve the above problem, the present invention provides, as a first means, two outer panels, and a space between the two outer panels and the outer panel. In this thin electronic device, an electronic component is housed in a plate-shaped casing consisting of a frame member provided on the outer periphery of the electronic component, and the electronic component is arranged near the inner periphery of the frame member.

Further, as a second means, in a thin electronic device having an electronic component housed in a plate-like housing made of two outer panels and a frame member, a support member is provided near the periphery of the electronic component. be.

(Function) According to the first means, the rod member portion has high rigidity, and even if an external force is applied to the outer panel, the amount of deformation near the rod member is small, so that the corner inside the plate-shaped housing No pressure is applied to electronic components placed near the rod members, such as the parts and edges. Therefore, damage to the electronic components housed within the plate-shaped housing is prevented, and performance can be maintained over a long period of time.

Further, according to the second means, the vicinity of the electronic component is supported by the support member, and even if an external force is applied to the outer plate, deformation of this portion is prevented, and no pressure is applied to the electronic component.

Therefore, damage to the electronic components housed within the plate-shaped housing is prevented, and performance can be maintained over a long period of time.

(Embodiment) An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

In FIGS. 1 and 2, 1 is a multifunctional IC card which is a thin electronic device, and this multifunctional IC card 1 has two outer panels, a front panel 2,
A printed circuit board 6,
It has a configuration in which a liquid crystal display device 7, a battery 8, a crystal resonator 9 as an electronic component, and the like are housed. In addition, the front panel 2, back panel 3, and guard frame 4
are made of a metal material such as SUS 304, and are welded together.

Further, the crystal resonator 9 is arranged at a corner within the plate-shaped housing 5, that is, at a corner of the guard frame 4, so that it is not easily damaged by external force.

That is, in the above configuration, the parts near the guard frame 4, especially the corner parts, have high rigidity, and even if an external force F is applied to the front panel 2 and the back panel 3, there is almost no deformation, and as shown in FIG. As shown in the figure, pressure is not applied to the crystal resonator 9 which is thinner than the guard frame 4 disposed at the corner and is not damaged. Therefore, it is possible to maintain the performance of the multifunction IC card 1 over a long period of time.

Note that the same effect can be obtained if the crystal resonator 9 is disposed not only in the corner portion but also in a nearby region E along the inner circumferential portion of the guard frame 4 shown by hatching in FIG.

Furthermore, as another example of preventing the transport of the crystal resonator 9, the arrangement shown in FIG. 5 may be used. That is, the crystal resonator 9 is surrounded by a metal rectangular frame-shaped support member 10 that is thicker than the crystal resonator 9, and the front panel 2
Further, even if an external force F is applied to the back panel 3, it may be supported by the support member 10 so that no pressure is applied to the crystal resonator 9.

Although the present invention has been described using a multifunctional IC card as a thin electronic device and a crystal resonator as an electronic component, the present invention is not limited to this. In addition, although the support member is made of metal and has a rectangular frame shape, it is not limited to metal.
Moreover, it does not have to be a rectangular frame shape.

In addition, it goes without saying that the present invention can be modified in various ways without departing from the gist thereof.

[Effects of the Invention] As detailed above, according to the present invention, although the structure is simple, damage to the electronic components housed in the plate-like housing is prevented, and performance can be maintained over a long period of time. This has the advantage that it is possible to provide thin electronic equipment.
