ABSTRACT:
DETAILED DESCRIPTION OF THE INVENTION
1. Field of the Invention
The present inventions relates to a computer system, a PC card, and connecting structure between a PC card and a computer system, and in particular, to technology that is effectively applied to connecting structure between a PC card for wireless LAN and a computer system.
2. Background Art
Recently, means for connecting to a telephone network or a communication network such as a LAN (Local Area Network) becomes indispensable for a PC (personal computer) user owing to the wide spread of utilization of the Internet or utilization of an office intranet. Owing to this, devices to connect a PC to a communication network, such as a modem and a LAN adapter become indispensable to a computer system.
There is a PCMCIA (Personal Computer Memory Card International Association) card as effective means for providing these communication devices as a CTO (Configure To Order) in response to a user's specification order or BTO (Build To Order) for a standard product. The PCMCIA card is a PC card standardized by PCMCIA (card type peripheral device for a PC), and includes memory, a hard disk drive, a modem, a LAN interface, and the like, or, for example, a SCSI (Small Computer System Interface) function for interfacing to other peripheral devices such as a CD-ROM drive, and a DVD-ROM drive.
There are five types of standards in the PCMCIA cards, that is, Type I, Type II, Type III, Type I extended, and Type II extended. All of Types I to III PCMCIA cards commonly have dimensions of 54.0 mm wide and 85.6 mm deep, and have thickness different from each other. The thickness of Types I, II, and III cards is 3.3 mm, 5.0 mm, and 10.5 mm or less respectively. The Type I card is used as a memory card mainly, and the Type II card is used for a modem, a LAN (Ethernet) adapter, a SCSI adapter, or the like. The Type III card is adopted as a built-in hard disk card mainly.
The Type I extended card and Type II extended card are extended cards in length that are longer than the Type I card and Type II card respectively. In an extruding section, a receptacle of a modular jack is provided, or an antenna for a wireless LAN is housed.
Problems to be Solved by the Invention
Although it is possible to connect a PC to a communication network by these PCMCIA cards, for example, if a PCMCIA card is a modem or a wired LAN, its cable management becomes a problem. If used as a modem card, the extruding section of the Type I extended or Type II extended card is used as a receptacle of a modular jack. In the case of the Type II card that does not have the extruding section, a conversion cable named as a dangle is used.
In the case of a desk-top computer system, it is approved to some extent, but when a computer system is used in a mobile environment like a notebook PC, complexity of cabling, and necessity of bringing the conversion cable obstruct user's convenience.
Then, it is expected to utilize a wireless LAN that does not cause the problem of the cable management. When the wireless LAN is going to be provided in a PCMCIA card, usually, it is not supposed that an antenna structure is supplied from a PC body. Hence a standard on a Type I extended or a Type II extended is used, and an antenna function is implemented in its extruding section.
Nevertheless, when the Type I extended card or Type II extended card is inserted into a PC body, as shown in
FIG. 10
, the extruding section A protrudes from the PC main body. With considering mobile use, the extruding section inconveniently becomes an obstacle for containing the PC in an attached case, and the extruding section may hit something to be failed. Therefore, it is preferable that the antenna structure is integrated in the PC body. Nevertheless, presently, there is not connecting means of the antenna structure inside the PC to the PCMCIA card not having the extruding section.
An object of the present invention is to provide the connecting means of the antenna structure, which is, in a PC body, to the PCMCIA card (PC card) that does not have the extruding section.
In addition, another object of the present invention is to provide means in which a cable does not become obstructive if the cable is used in this means, and which gives good impression to a user by making the appearance of the connecting means neat.
SUMMARY OF THE INVENTION
Hereinafter, the summary of the present invention will be explained. Thus, a computer system of the present invention comprises a housing, an antenna structure, a slot of the housing into which a PC card is inserted, a high frequency cable one end of which is connected to the antenna structure electrically and part of which is pulled outside the housing, a connector plug that is connected to the other end of the high frequency cable electrically and is outside the housing, and an elastic body or a cord take-up mechanism that is configured so that the high frequency cable is pulled inside the housing.
According to such a computer system, because the computer main body includes the antenna mechanism, it is not necessary to have the antenna structure in the PC card (PCMCIA card). Owing to this, it becomes possible to omit the extruding section because it is possible to use any one of Types I to III as the standard of the PC card. In addition, in a computer system of the present invention, a high frequency cable is used as connecting means of a PC card to an antenna structure of a PC body, and the computer system is configured so that this high frequency cable is always pulled into the PC body by an elastic body or a take-up mechanism. Owing to this, since an unnecessary high frequency cable is not pulled outside the PC body (housing), it is possible to make the appearance of the computer system neat. In addition, it is possible to avoid a contingency such as hitching of the cord, unnecessarily pulled out, during mobile use. Here, it is possible to exemplify rubber or a spring as the elastic body. It is possible to exemplify a coiled spring as the spring.
Furthermore, it is possible to form a channel, in which a cable is loaded, between a cable inlet in the housing of the computer and the PC card. By loading the cable in such a channel, it is possible not only to neatly treat the cable outside the housing and to make the appearance of the computer neat, but also to decrease a probability of an accident caused by the hitching of the cable.
In addition, it is possible to configure a PC card in length so that a connector plug does not protrude from a face of the housing in a status that the PC card is inserted in a slot and the connector plug is connected to a receptacle. At this time, it is possible to make the length of the PC card, which is in a direction of the PC card being inserted into the slot, be in a range of 75-80 mm. In this manner, it is possible not only to improve visual impression by getting rid of protrusion from an edge surface of the housing including the length of a connector, but also to decrease probabilities of accidents of hitching of the connector and the like.
Moreover, a computer system of the present invention comprises an antenna structure, a slot of the computer system into which a PC card is inserted, and a spring terminal connected to the antenna structure electrically, wherein the computer system is configured so that the spring terminal contacts to the outside of a housing of the PC card by the PC card being inserted into the slot. According to such a computer system, similarly as described above, it is possible to get rid of an extruding section of the PC card because it is not necessary to have the antenna structure in the PC card. In addition, since the connection of the PC card to the antenna structure is realized by the spring terminal, it is not necessary to pull the high infrequency cable outside the housing of a main body of the computer system, and it is possible to make its appearance neat, and to get rid of troubles of hitching, caused by the high frequency cable, and the like.
Furthermore, the PC card has a pad terminal connected to
