Description of the Invention: [Technical Field] The present invention relates to a memory card protection device, particularly to a memory card protection device for a memory card having a plurality of electrodes in an electrostatic state. [Prior Art] In recent years, the function of the memory card is superior to that of the hard disk or the optical disk, and the advantages of small size and large memory capacity are often applied to electronic products such as digital cameras, mobile phones, and portable music. Also commonly used in the computer's external memory device. When carrying and transporting a memory card from an electronic product, in order to prevent the data or electronic circuits in the memory card from being damaged by static electricity during the process, the memory card is usually placed in a special carcass with protection function. , carry and carry. However, the biggest reason why a memory card is damaged by static electricity is the human limb. This is caused by the discharge caused by the user's limb (palm, etc.) touching the memory card package. This phenomenon causes the stored data or electronic circuits to be destroyed. For example, when the user walks on a carpet, if the humidity is 1〇~2〇%, the user's limbs can reach 35kV', and the humidity is 65~90%, which is 1.5kV. 'If you use a charged finger, too close to or touch other conductive substances 1311975 (such as: memory card) and cause electrostatic discharge phenomenon, although the human body does not feel the discharge of 1~2 kV level discharge, I do not know that there is discharge, There will be a discharge situation that destroys the stored data. In order to avoid the occurrence of the first situation, as shown in FIG. 4, a plurality of memory cards 34 are mounted in a box 31 for storage, and the box 31 is in the housing shell-card body (4), and the degree of the coffee is expanded. The conductive conductive sponge can leak the static electricity carried by the memory card 34 by bringing the outer surface of the memory card 34 into contact with the card holder 33 when the memory card 34 is housed in the casing 3. Reference [Non-Patent Document 1] http://www.nakabayashi.co. iP/pr〇ducts/brand/digi〇/memorycase. htffll 0 When the memory card 34 is removed from the cabinet 31, the charged palm is required. Or the finger directly touches the memory card 34, and the discharge is inevitably caused. At this time, if a high-potential micro current flows through the outer surface and leaks to the card body frame 33, problems can be avoided, but if the micro current does not pass through the card body frame 33 And the electrode that is exposed from the outer surface of the memory card 34 is transferred into the interior', that is, the electronic circuit and the data are destroyed. • As shown in Figure 5, when the finger operates the memory card 34, in order to prevent the finger from directly touching the electrode 35 of the memory card 34, the electrode is disposed in the recess 36 of the outer surface; but if the finger is charged, as long as the finger is excessive The proximity electrode 35 (although the electrode 35 is not touched) can be discharged at a low frequency. At this time, since the electrode milk is disposed in the recess 36, it is difficult to contact the card holder 33, and the contact with the card holder 33 cannot be transmitted through the electrode (current will From the electrode 35 into the card body frame, the internal electronic circuit 'so the design also destroys the electronic circuit or data t show 1311975 That is, as shown in Figure 6, this design is the groove 3 6 is narrow and can not be The soft card body frame 33 is inserted into the recess 36, and even if there is a thin strip (which is a rubber material) having a shape suitable for the groove 36, it will be deformed during processing and difficult to process. [Disclosure] The object is to provide a memory card protection device that directly touches a memory card with a charged limb to cause a discharge, so that the electrical can be surely leaked without damaging the electronic circuit or the stored data inside the memory card. Memory card protection device, the present invention is for protecting a memory card having a plurality of electrodes in an electrostatic state, comprising a memory card storage device for accommodating a memory card and maintaining the state of the inserted memory card, having a socket and a An electrostatic protection circuit, the socket has a slot and a plurality of electrodes, the slot is for inserting a memory card, and the electrodes respectively correspond to electrodes of the memory card; the electrostatic protection circuit is formed by a wire connected to an electrode other than the ground electrode Electrically connected to the socket, having an electrostatic protection resistor, connected in parallel with the grounding point through the electrostatic protection resistor. If the memory card of the present invention is protected, if the memory card is inserted into the slot of the memory card storage device, the memory card is The electrode is connected to the electrode of the socket. Therefore, the electrodes of the memory card are arranged in the narrow narrow groove, and the electrodes can be respectively connected to the electrodes in the socket. And the electrodes other than the grounding wire in the socket are respectively The wire is transmitted through an impedance value lower than the memory circuit (eg, 1311975 5001 Ω Ω~2 Ω Ω electrostatic protection resistor) Parallel to the ground, the memory card and its electrodes are stored and held in the grounding state of the electrostatic protection resistor. Therefore, when the electrostatically charged arm directly touches the memory card to cause discharge and current is input to the electrode of the memory card, Since the electrodes of the memory card have been grounded below the impedance of the memory circuit, the high-potential micro-current generated by the discharge is actually discharged, thereby effectively preventing the electronic circuit inside the memory card or the stored data from being destroyed. The present invention will be described in detail with reference to the accompanying drawings.
