1. Field of Invention
The present invention relates in general to a data transfer device, and more particular, to a portable data transfer device to transfer data from a memory card to a hard disk or a blank compact disk.

In recent years, digital products such as laptop computers, cell phones, personal digital assistant and digital cameras have become more and more popular to provide various applications such as image/sound multimedia and data network transmission in our daily lives. The data of these digital products are normally saved in the light, thin, short and small memory cards such as secured digital (SD) card, compact flash (CF) card, smart media (SM) card, memory stick (MS) and multimedia card (MMC).
When the user needs to access the data saved in the memory card or when the capacity of the memory card is full, the data stored therein are transferred to a hard disk of a computer via a card reader installed at the computer. When the connection between the memory card and the computer is established, the card reader is then operative to save the data saved in the memory card into the hard disk. Or alternatively, a connection line (having USB connection port) can be used to connect the digital product and the computer to save the data stored of the memory card into the hard disk.
Currently, most of the digital products are portable and used outdoors. When the memory card is full, the data saved therein cannot be transferred into the computer immediately. Therefore, one or more than one backup memory card is always required. However, as the price of the memory cards are relatively high, the backup memory card is thus a burden to the user.
Therefore, a hard-disk type or a compact-disk type data transfer device is developed to provide direct storage of the data into the hard disk. Alternatively, the data can be burned on a blank compact disk by a compact disk drive for backup of the data. However, the user has to choose between the hard disk or the compact disk for transferring and saving the data. Therefore, when the user has only the compact-disk type data transfer device, the data has to be saved in a blank compact disk first before being saved into the hard disk. This causes great inconvenience for the user. In addition, the hard disk of the hard-disk type data transfer device is fitted in the data transfer device. During transportation, the data saved in the hard disk is easily damaged due to vibration or impact. Therefore, this type of data transfer device is not a safe data storage device.
A portable data transfer device includes a replaced magnetic storage device or a replace optical storage device is provided for transfer data saved in a memory card.
Accordingly, a portable data transfer device of the present invention includes a host equipped with a plurality of slots for installing various types of memory cards. A receiving slot is formed in the host to provide a replaceable hard disk drive or compact disk drive. To data transfer data from the memory cards to the hard disk or a blank compact disk, the memory card is inserted into the corresponding slot, and the hard disk drive or the compact disk drive is installed in the receiving slot. Thereby, the data transfer or reproduction can be performed more conveniently.
To install the magnetic storage device such as a hard disk, a fitting box having a size substantially the same as a receiving slot formed in a host is provided. The hard disk is installed in the fitting box, and the fitting box is then inserted into the receiving slot The hard disk includes a connector connected to a corresponding connector of a control circuit board of the host. Thereby, the hard disk is in electrical communication with the host, and the data saved in the memory card can be transferred into the hard disk.
The present invention will become more fully understood from the detailed description given hereinbelow illustration only, and thus are not limitative of the present invention, and wherein:
Referring to
A receiving slot 12 is formed in the host 1 allowing a replaceable magnetic storage device or a replaceable optical storage device installed therein. In this embodiment, the magnetic storage device includes a hard disk drive 3, for example. The hard disk drive 3 has one end connected to a circuit board 31 on which a connector 32 is formed to connect the corresponding connector of the control circuit board 100 of the host 1. The hard disk drive 3 is inserted and carried by a fitting box 4, which is then inserted into the receiving slot 12 of the host 1. Therefore, the size of the fitting box 4 is substantially the same as that of the receiving slot 12 of the host 1.

According to the above, the portable data transfer device 10 as provided allows the installation of a replaceable hard disk drive 3 and a replaceable compact disk 5. Therefore, data saved in memory cards 2 of various specifications can be transferred to either the hard disk 3 or a blank compact disk as desired. By the replaceable structure of the hard disk drive 3 and the compact disk drive 5, the user can selectively make backup data in either drive.
The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
