Description

Memory card structure

The present invention relates to a kind of memory card structure, and more particularly, to a kind of novel memory card structure, which is itself connected to a USB interface system stage, and at the same time a memory card structure which is itself a small memory card storage device. will be.

The information product market is already showing rapid development of products with small size, high capacity and multimedia functions. For example, NBs, computer peripherals, PDAs, Web-PADs, digital cameras, and digital camcorders are all getting smaller, but the data storage capacity is growing with various functions. As a storage medium with convenience and efficiency of data storage, various products of various standards such as the following are currently released, such as Sony's Memory Stick card, Matsushita's Secure Digital card, Compact Flash card, Multi Media card, Smart Media card, etc. There are so many kinds of. All of these memory cards are made of "Semiconductor Storage" and are called recordable memory / flash memory. They are not only small in volume, but also low in power consumption, data retention, data transfer rate, and redundancy. It is much better than conventional optical storage or magnetic storage technology in recordability, shock resistance and moisture resistance.

The Universal Serial Bus (USB) interface specification, released in 1996, is a kind of compatibility expansion interface for a computer system or a portable device. It has several advantages. This expansion interface design has already been developed for various products, such as computer systems (desktop or notebook), peripheral products (e.g. scanners, keyboards, printers, mice, etc.), as well as various information appliances (IA; It is being applied to PDAs, digital cameras (DSCs), digital walkers (MP3 players), portable hard disks, etc.) and is loved by consumers for its ease of use. As USB and various memory cards are applied to products in almost all areas at the same time, the interest of consumers is increasing day by day. Various types of memory card reproducing facilities (namely card reading machines / memory card machines or switching connectors) have been produced in order to increase data transfer and distribution in devices equipped with memory cards and various USB system stages. Examples include external memory machines, internal memory card machines, and memory card switch connectors.

However, although consumers can purchase the appropriate memory card machine and play the data for memory cards of different specifications currently on the market, it is also true that there are some limitations in the selection of future digital products. For example, if people around you don't use MS Cards or can't easily buy MS Cards, you're hesitant about buying digital cameras from Sony that use MS Cards. Conversely, consumers who have already purchased a Sony digital camera will not necessarily buy a Sony PDA the next time they do not want to use another type of memory card. This variety of memory cards limits consumers to two factors: product and price. This also explains whether companies are competing for the preemption of memory card specifications despite huge capital input. This is because the preoccupation of memory card specification initiatives is correlated with huge profits.

In particular, the advent of portable hard disks is getting more heated with the attention of consumers. It is a recordable memory that has the characteristics of the above-mentioned high storage capacity and redundant recording, which has a standard USB specification, and can be plug-in-played at any time by directly connecting to a computer or other USB-equipped connection slot, and other types of consumption It is also possible to transfer and exchange data directly with electronic products and digital communication devices. In other words, it is a kind of small portable hard disk that has the convenience of storing and modifying data. It is equipped with a USB system interface so that data between desktop computer, handwriting computer, or handheld computer can be changed from time to time. For example, MP3, VIDEO, It supports exchange of various digital information such as PHOTO.

However, current small memory cards of various specifications can all be connected to a computer or other device equipped with a USB interface via a single media player (e.g., the external memory machine, internal memory card machine and memory card switch connector described above). do. In addition, although portable hard disks are directly connected to the USB system, digital devices such as general appliances, digital cameras, and PDAs are difficult to embed USB interfaces, so they cannot be applied to devices of all memory card interfaces. In other words, both of these devices (memory cards or portable hard disks) are both indirectly or directly connected to the USB system, but both are not useful. Therefore, the purchasing cost of the consumer rises, causing inconvenience to use.

In order to solve the above problems and reach other functions and purposes, the inventors have invented a kind of "new memory card structure," which is a newly developed memory card structure, which is directly connected to the USB system stage. Its own interface allows applications to playback players.

Another object of the present invention is a newly developed memory card structure having an external size for using a USB slot, in addition, a plurality of interface leads (PIN) is installed, four of the interface leads of the USB system stage Not only does it connect to four signal terminals for data transfer and exchange, but it also connects to the interface terminal of the corresponding device with multiple interface leads of the memory card itself, and also for data transfer and exchange with other types of interfaces. To make it happen.

Another object of the present invention is to place a gradually shrinking rectangular plate on the front of the small memory card, in particular, the size of the rectangular plate to be inserted directly into the USB connection port to meet the USB standard in the design of the electrical signal It is to proceed with the transmission and storage of data. The rectangular plate of the present invention can achieve the same effect and object even if the height occupies only half the space of the USB connection port. With this design concept, the size of the present invention has become smaller and is consistent with the trend of digital information products that are becoming smaller day by day. The present invention solves the problems such as consumer inconvenience and cost increase in addition to the purpose of using the direct USB standard.

However, other structures and design concepts of the present invention are similar to a general memory card, so only some of them will be described herein. For example, the interface lead is fixed to the square plate by a flat pasting method, and the write protection device has a design of a right angle surface and one inclined surface.

Hereinafter, the present invention will be described in more detail with reference to the drawings.
