Description

Computer peripheral device with dynamic memory function

Technical field

The utility model is the computer peripheral device that has the dynamic memory function about a kind of, more specifically, especially refer to a kind of tool with inserting with USB port device with function, and with the various computer input peripheral equipment of the auxilary unit of the access facility that stores great mass of data.

Background technology

Making rapid progress of electrical appliance and PC, new product commonly used is asked the city and is all constantly weeded out the old and bring forth the new towards the target design compact, that function is superpower.As thick and heavy cathode ray tube (CRT) display, gradually replaced by frivolous liquid crystal (LCD) display; 51/2 " soft disc player is by 31/2 " soft disc player replacement; And 31/2 " FLOPY also have by electronic type and store the trend that wafer replaces, this is because of 31/2 " storage volume of soft dish is limited, the capacity that is increased even if compress technique makes progress is also limited.In addition, FLOPY is because of being to utilize the mechanical type read/write head to carry out the read-write of data, so speed is also slow, add existing Games Software or application package less often number pick up megabit units, big then hundreds of megabit unit not only, real non-floppy drive magnetic sheet can hold.Yet read-write CD player (CD-R) because of main frame is quite big, is carried inconvenience though can solve storage, the distribution problem of above-mentioned high capacity data, for data carry and transmit comparatively unfavorable.

In addition, the data storage device that present commercially available dynamic memory chip is formed is not wanted data to disengage storage space because of it does not need UV-device consuming time to eliminate, and with the direct repetitive read-write of electric mark, speed is very fast, and memory capacity is big again, and the again little reality of volume is the sharp weapon that store data.So, general laptop computer all disposes a mouse pad (or little rocking bar) below keyboard, vernier moves point of destination on the controlling computer gently pressing on the mouse pad and move to utilize finger, but because of this mouse pad (or little rocking bar) mobile range very little, so finger needs slowly operation, otherwise be difficult for accurately moving on to point of destination, quite time-consuming, therefore there is the people to carry a mouse in addition and is marked with the vernier of conveniently controlling laptop computer and moves; As for portable type dynamic memory box, then must buy one in addition and carry.

And universal serial port (USB PORT) can be supported multiple computer peripheral device such as mouse (Mouse), keyboard (Keyboard), recreation rocking bar (Joystick), game paddle (Game Pad), electronic equipments such as digital still camera, purposes is very extensive, advantage at dynamic storage: the dealer has designed a kind of dynamic storage by PC universal serial port (USB) and has carried box now, this box body is long-pending to have only size as the matchbox approximately, and inserting behind the USB mouth can be fast and a large amount of (now have 256M than 31/2 " FLOPY 1.44M be a large amount of) the computer inside information is stored in this capsule.The laptop computer user might have these two kinds of equipment (dynamic memory carries box), (connecing mouse soon) certainly simultaneously, but if will carry simultaneously and still dislike inconvenience also very economical slightly, so numerous parts is arranged is repetition because both support the outfit of USB equally.

Conclude and above-mentionedly apprehensiblely be, no matter with present single Storage Media, be built-in or be external on the computer (or laptop computer), all can increase the equipment of original host, and then cause space hold, cost expenditure, or even use the scarce frauds such as situation generation that go up inconvenience; In view of this, this creator actively seeks solution, and to be engaged in the manufacturing of PC peripheral equipment for a long time and to sell experience, and professional knowledge and attainment, through constantly design, design, and computer input peripheral equipment that will be general common is in conjunction with USB communication standard, and the form that its control program is combined with dynamic storage controller, the computer peripheral device with dynamic memory function of creating this practicality eventually is answering demand, and the phase can be for popular convenient the use.

Content of the present utility model

Be that the purpose of this utility model is to provide a kind of computer peripheral device with dynamic memory function, its mainly be with the dynamic memory chip or in be built in computer peripheral device and (reserve dynamic memory chip hole slot as the outer box of connecting line group shared in mouse, keyboard, recreation rocking bar, game paddle, the PC digital still camera and plastic cement or on its plastic box surface, or be that built-in the two all builds the form of putting use simultaneously with reserving slot.Because of the volume of storer own is very little, need not strengthen the volume of original computer input peripheral equipment, therefore, not only can reduce cost and reduces the trouble of carrying, facility in the extreme.Thus, these peripheral equipments of military order can not only be possessed outside the former function, still have the additional functionality that stores great mass of data, and the access of data do not need to be dependent on soft on the main frame, hard disc fully, and ward off a kind of auxilary unit easily in addition.

It is a kind of computer peripheral device of the utility model with dynamic memory function, its circuit structure comprises: the microprocessor with program storage, random access memory and output, input processing capacity, the power processor that suitably uses with voltage at part, in order to show the pilot lamp of the state that standby and data are transmitted, select button, peripheral equipment function inductor, the dynamic memory chip of dress in it is characterized in that being provided with, other is provided with in order to the USB communication interface processor that is connected with the USB port of host computer.

Of the present utility model being further characterized in that is provided with the multiple-contact socket that extrapolation dynamic memory card is provided, peripheral equipment is electronic equipments such as mouse, keyboard, recreation rocking bar, game paddle or PC digital still camera, built-in and external dynamic memory card in this peripheral equipment all can be present in simultaneously or optional wherein a kind of form one combines with computer peripheral device.

By this, connection by the USB interface, make the archives material of computer inside can transfer to peripheral equipment and be stored in the inner memory chips, and the archives that have been stored in this peripheral equipment also can return in computer, and that this peripheral equipment can be kept operate as normal is unaffected; And behind the peripheral equipment off-line, the data of its storage auxilary unit with long preservation period.

Be the effect that further specifies architectural feature of the present utility model, purpose and realized, enumerate several preferred embodiments and conjunction with figs. now and describe in detail as the back:
