Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a computer peripheral device, and particularly to an auxiliary memory drive for a computer.

[0002]

[Prior art]

 As is well known, for computer processing, in addition to reading and writing data from and to a main memory inside a CPU and a hard disk, for example, a magnetic disk drive 1 or an optical disk drive 4 belonging to an auxiliary memory as shown in FIG. Used in addition to pewter peripheral equipment. The most widely used of these is the magnetic disk drive 1. As shown in FIG. 1, what is used for the magnetic disk drive 1 is a magnetic resin coated magnetic resin disk 2 having a plastic cover 3 on the outer peripheral surface for protection. Its size is about 0.2-0.3 cm in thickness and about 9-13.3 cm in width. Like the magnetic tape, the magnetic disk 2 reads and writes data using the magnetic principle, and reads and writes by the magnetic head 1a in the magnetic disk drive 1. The magnetic head 1a and the magnetic head in the tape recorder are almost the same.

However, since the capacity of a general magnetic disk is not large, when storing a large amount of data, it is often necessary to distribute and store the data on several disks. In particular, in the case of large-format design data, there may be situations where saving operations are not possible. The capacity will increase if a disk drive dedicated to double-sided high-density discs is used, but the storage capacity is still only 1.2 MB. In this case, it is impossible to memorize even larger-format designs at once. That is, it is very inconvenient in use. In addition, there is a problem that the number of magnetic disks possessed by the user increases steadily with the additional purchase of magnetic disks. The enormous volume is an enormous burden due to storage management, making it even more inconvenient to carry.

On the other hand, the optical disk drive 4 is based on the application of laser technology, and does not use a magnetic head for reading and writing in the optical disk drive 4, but uses two different laser beams for reading and writing. The optical disk 5 stores data due to a property change caused by light on a substance on its surface. Since the laser beam can be concentrated on a very small area, the capacity of the optical disk 5 is usually very large. One 12-inch optical disk 5 can store 4 GB of data. That is, one 12-inch optical disk 5 can replace 2100 40 MB magnetic disks. Generally, the data read / write density on the optical disk 5 is about 20 times that of a general magnetic disk. However, optical disk drives that can be read and written are very expensive and are difficult to spread. Therefore, most of the currently used optical disk drives 4 are read-only and do not have a write function. In addition, when writing data, a separate optical disk writer (not shown) is required. However, laser beam writing technology is complicated, has a high failure rate, and is very inconvenient.

[0005]

[Problems to be solved by the invention]

 Therefore, an object of the present invention is to provide an auxiliary memory drive for a computer which achieves high speed and high capacity of read / write operation of a computer auxiliary memory, greatly increases a service life, and is convenient to store and carry. is there.

The case main body 10 is configured by a lid 11 and a bottom base 12 that are vertically closed. A pair of key-shaped engaging connection portions 111 are symmetrically protruded from bottom edges on both left and right sides of the lid 11, respectively. The base 12 has a box shape corresponding to the shape of the lid 11, and a pair of fitting tanks 121 are formed at positions corresponding to the engagement connection portions 111 on both left and right sides of the lid 11. In this way, the upper and lower sides can be closed and fitted together. A horizontal port 13 having a width of about 5.4 cm is formed on the front side of the base 12, and a housing space 14 having a depth of about 8 cm is formed vertically from the horizontal port 13 to the inside as shown in FIG. A positioning partition 15 is fixed above the accommodation space 14. The positioning partition 15 has a rectangular window 151, and a guard piece 152 extending horizontally is vertically provided at an appropriate position on the rear end side of the window 151. An interface insertion section 16 of a versatile serial bus is fixedly provided at the bottom of the housing space 14 on the shaft side.

The memory card 20 is an ultra-thin rectangular card body having a side width 21 of about 0. 08 cm. Since the width 22 corresponds to the width of the horizontal opening 13, the memory card 20 can be inserted into the horizontal opening 13 of the case body 10 and stored in the storage space 14. A high-speed blinking memory IC 23 is provided therein. The high-speed blinking memory IC 23 includes a main IC 231 and a memory IC 232, and has a standard of 100,000 reading and writing, so that high-speed reading and writing of data is possible.

The card terminal connector 30 is a box, includes an IC circuit board 30 A, and is installed in parallel with the horizontal port 13 and horizontally. The end face 31 is exposed downward to the window 151 of the positioning partition plate 15 and corresponds to the position of the reading area 24 of the memory card 20 inserted into the accommodation space 14. One contact 32 is pivoted. As a result, the elastic piece contact 32 comes into contact with the contact 241 of the reading area 24 in a vertical direction, so that a signal reading connection operation can be performed. A wiring 33 is fixedly provided on a side surface of the card terminal coupler 30, and the wiring 33 is connected to the interface insertion portion 16 of the case body 10.

The transmission conductor 40 has a versatile serial bus design. At both ends, the interface insertion portion 16 of the case main body 10 and the versatile serial bus insertion provided on the CPU 50 shown in FIG. A series terminal 41 corresponding to the unit 51 is provided. Thereby, the CPU 50 and the case body 10 can perform serial high-speed input / output.

Next, the serial terminal 41 of the transmission lead wire 40 is inserted into and connected to the interface insertion portion 16 of the case body 10 and the versatile serial type bus insertion portion 51 installed on the CPU 50 to complete the combination of this embodiment. I do.

In use, as shown in FIGS. 4 and 5, the memory card 20 is simply inserted into the horizontal opening 13 from the side thereof. The bottom end of the ultra-thin memory card 20 is guided downward at the horizontal opening 13 and very quickly reaches the position of the guard piece 152 at the bottom of the storage space 14 and stops. At this time, since the card terminal connector 30 is exposed downward at the window 151 of the positioning diaphragm 15, the card terminal connector 30 utilizes the compressible elastic piece contact 32 on the end face thereof to form the memory terminal. The divided contact 241 of the reading area 24 installed in front of the card 20 is pressed into contact. Since the reading area 24 of the memory card 20 and the resilient piece contacts 32 of the card terminal connector 30 are pressed against each other, the signal of the operation process of the CPU 50 can be quickly transmitted and recorded.
