Description

All-in-one Silicon Disk Drive

technical field

The invention belongs to computer components, in particular to an all-in-one silicon disk drive.

Background technique

The silicon disk drive is a readable and writable silicon disk (portable memory card) device. Silicon discs are widely used in IA-Information Appliances and a number of portable digital products due to their excellent characteristics such as thinness, lightness, high storage capacity, shock resistance, and repeatable memory. For example, popular products in the market such as Personal Digital Assistant (PDA), Digital Camera (DSC), Digital Walkman (MP3 Player), etc., almost all use silicon discs as storage media.

Just because IA is an emerging field with novel and diverse products, the silicon disc standard has become a market segment that international manufacturers are striving to develop and compete for. At present, there is no uniform standard and specification for silicon disks in the world. The related products are not only diverse but also have their own market advantages. Effective circulation cannot be achieved with the computer system and computer peripheral equipment, which also causes inconvenience to consumers in use.

A brief description of the various silicon discs currently in circulation is as follows:

1. PC card (PCMCIA ATA Flash Card)

The PC card specification is a memory card exclusive specification formulated by the Personal Computer Memory Card International Association (PCMCIA). This standard specification is 85.6mm in length and 54mm in width. ), Type III (10.5mm), mainly used in notebook computers (Notebook PC).

2. CF card (Compact Flash Card)

The CF card specification is a very thin and short memory card, with a length of 43mm and a width of 36mm. According to its thickness, it is divided into two types: Type I (3.3mm) and Type II (5mm), which are small in size, light in weight, Good data preservation, high reliability, and power-saving characteristics, so it is quite popular in consumer electronics products, mostly used in IA products such as personal digital assistants (PDA), digital cameras (DSC), and digital players (MP3 Player) on the peripheral equipment.

3. SM card (Smart Media Card)

The thickness of the SM card specification is only 0.76mm. The manufacturer directly uses the flash memory in a special card package. Its electrical interface is the same as that of the manufacturer's flash memory. It is mainly used in digital cameras and digital players.

4. MMC card (Multimedia Card)

The specifications of the MMC card are the smallest silicon discs on the market, with a thickness of only 1.4mm and a serial interface. They are mainly used in digital players, mobile phones and other fields.

5. MS card (Memory Stick Card)

The appearance size of the MS card specification is about the same as a piece of Wrigley chewing gum, and it adopts a serial interface. The patented board of this silicon disc is exclusive to SONY, and is authorized to be used by other manufacturers. At present, the products using MS cards in the market are all developed and sold by SONY, including digital cameras, digital players, PDAs, mobile phones combined with players and Internet functions, and personal computers.

6. SD card (Secure Digital Card)

The thickness of the SD card is 2.1mm, and the other dimensions are the same as the MMC card. It also adopts a serial interface. It is mainly used in the digital player, digital camera, and PDA market.

Since the specifications and sizes of the various silicon discs mentioned above are not the same, and in order to adapt to the rapid rise of information appliances and the situation that the specifications of silicon discs are not uniform, various manufacturers have developed various silicon discs that can support different silicon discs. Specifications of silicon disk drive products to meet market demand. However, there are multiple standards for silicon disks. Therefore, silicon disk drive manufacturers have no choice but to add slots to silicon disk drives to support silicon disks of various specifications, such as three slots that support three silicon disk specifications, support for Four-slot silicon disk drive products with four silicon disk specifications.

The method and structure of this conventional multi-slot silicon disk drive can solve some of the problems of non-uniform silicon disk specifications, but it brings more problems and inconvenience to users:

1. Too many slots cause confusion in use: For example, the silicon disk drive used by the user is a four-slot model, which can support four specifications of silicon disks: SM, MMC, MS, and SD. However, after the multi-slot silicon disk drive is connected to the system and turned on, the screen will only display multiple symbols such as F slot/G slot/H slot/I slot, and will not show SM slot/MMC slot/MS slot/SD The marks on the slots make it difficult for the user to easily determine which mark represents which memory card has been inserted into the slot, which is likely to cause confusion in use.

2. Too many slots cause inconvenience in use: If the silicon disk drive supports IDE/ATAPI system interface. When interfacing with the system, only two slots of the four-slot silicon disk drive can be used at the same time (in terms of IDE/ATAPI support with the host side, each connection can only provide two sets of different signal processing at most), and the remaining two slots are used. It's like a fake. When the user intends to read/write to the third memory card at the same time, the slot will not work, and even cause the system to crash.

3. Others such as: due to too many slots, the user inserts the wrong slot by mistake and damages the silicon disc or slot, increases the manufacturing cost, is too large, and has poor built-in support. Some conventional silicon disk drives with more than three slots have a major lack.

Detailed ways

As shown in FIG. 1 , the present invention is built in a computer host system 10 or other digital products, which includes a main body 20 , a first slot 30 , a second slot 40 and a transmission unit 50 .

The appearance of the main body 20 is designed as a rectangle suitable for embedding into the computer host system 10 or other digital products. It has a space for accommodating circuit boards and other electronic components inside. Its front end is provided with a first slot entrance 21 and a second slot entrance. 22, and the first slot entrance 21 and the second slot entrance 22 are located on the outer edge of the computer host system 10, so that the memory card 60 can be inserted into the main body 20 through the first slot entrance 21 and the second slot entrance 22.

The first slot 30 is disposed in the main body 20 at a position corresponding to the first slot entrance 21 , and the second slot 40 is disposed in the main body 20 at a position corresponding to the second slot entrance 22 . Therefore, when the memory card 60 is inserted into the main body 20 through the first slot entrance 21 or the second slot entrance 22 , it can interface with the first slot 30 or the second slot 40 .

As shown in Figure 2, the first slot 30 is in the shape of a lateral U, the middle part of which is a clamping area 31, and at least four groups of different lengths and widths are provided on the clamping area 31 to guide the dimensions respectively. The guide slots 32 of the similar SM, MMC, MS and SD memory cards 60, so that any one of the memory cards 60 of the above four specifications can be inserted into the card system area 31 through one of the guide slots 32 guides , and fixed on the first slot 30. After the memory card 60 is fixed in the first slot 30 , it can transmit signals to the circuit board preset in the aforementioned main body 20 .

As shown in Figure 3, the second slot 40 is in the shape of a lateral U, the middle part of which is a clamping area 41, and at least multiple sets of different lengths and widths are provided on the clamping area 41 to guide the lengths respectively. And the guide slot 42 of the TYPE I, TYPE II, TYPE III memory card 60' of the PC card with the same width but different thickness, and the memory card 60' of any one of the thicknesses can be fixed in the second slot 40. Similarly, after the memory card 60' is fixed in the second slot 40, it can transmit signals to the circuit board preset in the aforementioned main body 20.

As shown in FIG. 1 , the transmission unit 50 is connected between the computer host system 10 and the main body 20 and is mainly used for transmitting signals. When the memory card 60 (or 60') is inserted into the main body 20 through the first slot entrance 21 (or the second slot entrance 22), the circuit board preset in the main body 20 can read the memory card 60 (or 60'). The stored files are transmitted to the host computer system 10 through the transmission unit 50, and the information returned by the host computer system 10 can also be transmitted to the memory card 60 (or 60') for storage through the transmission unit 50, so that the memory card 60 (or 60') to perform read and write functions.

As shown in FIG. 1 , the main body 20 of the present invention is built in the host computer system 10 or other digital products. Therefore, the transmission unit 50 should adopt the IDE/ATAPI system interface specification. The transmission unit 50 of the IDE/ATAPI system interface specification is designed based on the principle of built-in processing, while IDE/ATAPI supports the computer host system 10, each line can only provide two sets of different signal processing at most, according to its definition The Master and Slave architecture, that is to say, although the conventional three-slot or four-slot silicon disk drive can also be designed to support the IDE/ATAPI system interface specification, but in fact, when used, the machine can only support the insertion sequence The first and second types of memory cards with different specifications cannot handle the signals of the third and later types of memory cards, and in severe cases, it may even cause a crash.

However, the design of the first and second slots 30, 40 of the present invention has just met this standard definition, because the first and second slots 30, 40 of the present invention can allow memory cards of various specifications to be embedded. , but only one type of memory card can be inserted at a time. Therefore, it is possible to avoid the situation that the aforementioned conventional three-slot and four-slot silicon disk drive inserts a third type of memory card and causes the machine to crash.

That is to say, the present invention has a wider use space than the known three-slot and four-slot silicon disk drives, and can allow SM, MMC, MS, SD cards and PC cards with seven specifications such as TYPE I, TYPE II, and TYPE III. Memory card insertion, far more than the conventional three-slot and four-slot silicon disk drive, only allows three or four types of memory cards to be inserted, which has a wide range of applications, and will not confuse consumers or install more than three pieces of memory at the same time card and cause a crash.

As shown in FIG. 1 , FIG. 2 , and FIG. 3 , the main body 20 of the present invention is directly built into the computer host system 10 or other digital products. And in order to cooperate with users who currently have computer hosts or other digital products that cannot be built in, it is also possible to design the transmission unit 50' as system interface specifications such as USB or 1394, and connect the main body 20 to the existing system as shown in Figure 4. There is a host computer for reading and writing the memory card.

As shown in FIG. 5 , the present invention includes a main body 20, a first slot 30 and a transmission unit 50 (50'). The appearance of the main body 20 is designed as a rectangle suitable for embedding into a computer host system 10 or other digital products. It has an accommodating space for circuit boards and other electronic components inside. The front end is provided with a first slot entrance 21, and the first slot The slot entrance 21 is located on the outer edge of the computer host system 10 to facilitate the insertion of the memory card 60 into the main body 20 through the first slot entrance 21 . It can at least read and write four kinds of memory cards 60 such as SM, MMC, MS and SD cards.

In addition, the aforementioned second slot 40 is designed to match the TYPE I, TYPE II, and TYPE III specifications of the PC card, and can also be designed to match the TYPE I and TYPE II specifications of the CF card. The principle and structure are the same.

The present invention can insert existing SM, MMC, MS and SD cards with similar size into a slot with a single entry, while TYPE I and TYPE II of CF card or TYPE I, TYPE II and TYPE III of PC card can be inserted in another slot A slot with a single entrance is inserted, so as to read and write the file data of any of the above-mentioned silicon discs, and the design of the IDE/ATAPI, USB or 1394 transmission unit is supplemented, so that the present invention of the above-mentioned single or double-slot design can For insertion, reading and writing of all memories currently in circulation.

That is, the single or double slot design of the present invention can support multiple silicon disc specifications at the same time, so that various silicon discs can be used in a simpler and more convenient way with various portable products, personal Computers and computer peripherals provide barrier-free communication, provide users with excellent convenience, and eliminate the confusion that conventional technologies may cause users. With the simplistic design of the present invention, and supplemented with IDE/ATAPI, USB or 1394 transmission unit design, the present invention can be easily built-in or externally connected to computer host systems of various specifications and related peripheral devices to suit various To meet the needs of consumers, silicon discs with multiple specifications can be integrated so that silicon discs can better meet the market mechanism. In addition, in the past, due to the inability to standardize the specifications of silicon disks, system manufacturers hesitated whether to build silicon disk drives into the system, which indirectly caused disturbances among all kinds of silicon disks. The loss of rights and interests, and through the present invention, the silicon discs that cannot be standardized at present can overcome the technical problems encountered in the system's built-in.
