Abstract

PURPOSE: A flash memory card drive is provided to correspond to a card having a WPS(Write Protect System) manufactured by a method for cutting a lead line out of flash memory cards. CONSTITUTION: In the case that even-numbered lead lines(including zero) out of many lead lines of a WPS of a flash memory card(8) are cut, if the flash memory card(8) is inserted into a memory card drive(1), an MPU(Micro Processor Unit) of the drive senses the flash memory card(8). Thus, a file included in the card(8) is deleted and a recording process is performed. Otherwise, if odd-numbered lead lines are cut out of many lead lines of the WPS, the recorded file does not be deleted and an overlap function is prevented, and thus data are protected. At this time, two indicator lamps(5,6) are used for checking a correct insertion of the flash memory card(8) and for checking a recording and a reading of the flash memory card(8) reliably.

Description

Flash memory card drive {FLASH MEMORY CARD DRIVE}

The present invention connects a flash memory card made in a card form with a built-in flash memory chip to a PC to store and store music files, image files or general data contained in a PC (HDD) on a flash memory card, or It's about a flash memory card drive that can read data, type it into a PC, or erase data on the card.

The original recording medium has a WPS (wipe protection device), and the floppy disk has a hole in the lower left, so that the drive detects when the disk is inserted and protects the recorded data from being erased.

In addition, FDD (FLOPPY DISK DRIVE) or CDR (CD ROM) drive, which is used as an auxiliary to HDD (Hard Disk Drive) in PC, inserts a disk as well as a device that drives a disk and tracks a disk track. It must have a device and a disk ejector to indicate that the seating device and the disk are mounted in the drive.

The biggest object of the present invention is to correspond to a card having a WPS (erase protection device) in which a lead wire is disconnected among flash memory cards.

That is, the input / output is adjusted so that the file stored in the flash memory card is not erased according to the state of the lead wire.

In addition, the advantages of the flash memory card drive: there is no driving motor, and only the contact point can be used to realize various convenience stores.

The configuration of the present invention is a flash memory card drive made in accordance with the present invention of FIG. 1, a block diagram illustrating the connection between the flash memory card drive and the flash memory card drive (WPS) of FIG. An example of the case where a card is used (a dual card system) and a structure diagram of the case where the flash memory card is inserted into the drive of FIG. 4 will be described below.

The flash memory card is made in the form of a card with a built-in flash memory chip, and can store all digital files: music files, image files, or general data files, and the present invention can be executed by connecting these operations to a PC. Is for a flash memory card drive.

In general, a recording medium for recording data has a device that can protect the contents by preventing accidental deletion of recorded contents. This is called WPS (WRITE PROTECT SYSTEM).

WPS can be any of a number of ways, and if a recording medium such as a disc requires WPS (protection), the device will be punched out. When a disc is inserted into the drive, the drive detects this hole and prevents data from being deleted. .

In the drive of the present invention, the even number of the lead wires of the WPS of the flash memory card (even number including 0, 0 is no lead wire) can be used to use a flash memory card having a lead-breaking WPS. If a lead in the unbroken state is broken, the MPU (microprocessor unit) in the drive detects this, inserts the file on the card, and writes over it, or writes an odd number of leads in the WPS. This prevents the file from being erased and protects the recorded data by preventing overlapping.

In addition, two indicator lamps are used to make sure that the flash memory card is actually inserted into the flash memory card drive. (STAND-BY) indicates the ready state (STAND-BY) and both lamps flash when the flash memory card is not inserted or the card is not in the correct state.The other lamp indicates that the drive writes to the flash memory card (PC → When the flash memory card is downloaded (WRITING) or when the contents recorded on the flash memory card are read (flash memory card → PC uploading: READING), it lights up, so you can check the correct operation.

Since the flash memory card is made of contacts only without motor driving, the card mounting unit can be made very compact, so the dual card system (DUAL CARD SYSTEM: uses two card connector sockets for two simultaneous flash memory cards) can be used. For application, it can be either side by side horizontally or vertically. When two cards are used at the same time, one card can be exchanged while the other card is being read. In addition to doubling the, you can also copy from card to card, which is very convenient.

Similarly (as it is only a contact), if a portion of the flash memory card protrudes out of the drive (usually 5 to 7 mm), it is easy to see if the card is inserted into the drive, and you do not need to eject the card. Grab some of the exposed cards and draw them.

The flash memory card drive of the present invention made in this way enables the use of a flash memory card with a disconnected lead wire, and additionally, two indicator lamps aid in the identification use of the flash memory card drive, and a dual flash memory card By operating the system and using the protruding part of the card, it is easy to confirm insertion and bypass the ejection mechanism.

Claims (1)

It is a flash memory card drive that can input / output data by connecting to a PC so that digital files such as music files, image files or general data files can be stored in a flash memory card that has a built-in flash memory chip. If the even number of lead wires (including zeros) of the WPS of the flash memory card of the flash memory card, which is a WPS (breaker prevention device) that breaks the lead wires, is inserted, insert the MPU (microprocessor unit) of the drive. Detects this, erases the file on the card and writes on it, and if you break the odd number of WPS leads, you can't erase the recorded file, preventing overlapping and protecting the recorded data. Using two lamps, one indicates that the card is inserted correctly when the card is inserted, and is ready (STAND-BY) for data input and output operations. The other lamp indicates that the drive writes to a flash memory card. WRITING) or lights up to read the contents recorded on the flash memory card, The dual card system (DUAL CARD SYSTEM: uses two card connector sockets) can be used to insert two flash memory cards at the same time. Only the contacts can cause part of the card to protrude out of the drive, making it easy to see if a card is inserted into the drive and without having to eject the card. Flash memory card drive
