The utility model is characterized in that an ISA driving card which can be inserted in the ISA slot of a computer is connected with an ISA adaptation card through a conducting wire. The ISA adaptation card and a plurality of ISA slots which are plugged with the gold tax cards are connected by a multiway selection switch circuit. A plurality of IC card sockets corresponding to a plurality of ISA slots which are plugged with the gold tax cards and a public IC card input device are connected by a multiway selection switch circuit. A plurality of enterprises share one set of computer system to use the gold cards, a main unit cabinet of the computer doesn't need to be opened, and cards can be pulled and inserted to realize one machine with multiple functions.
Description
The utility model belongs to the computer integrated manufacturing system field, relates to a kind of tax-card controller, is a kind of multi-user's antifakery tax-card divider specifically.
Tax-card is the control card that is used for opening VAT invoice that revenue department provides to enterprise, there is different tax-cards in different enterprises, during use tax-card is inserted the ISA slot of computing machine, read in IC-card information again, import invoice amount on keyboard, computing machine just prints VAT invoice, and tax information has just been stayed on the tax-card, the amount of tax to be paid of tax card appointment can be reused after need declaring dutiable goods to revenue department once to not printed VAT invoice.Therefore tax-card has stronger antiforge function with respect to present widely used papery VAT invoice, also helps tax revenue, is a kind of control card that country widelys popularize.
Using the prerequisite condition of tax-card at present is that a cover computer system is arranged, that is: a computing machine, a printer, a display, a keyboard, about 15000 yuans of required expense, need the zooming accounting in addition, this is for many enterprises, especially to those computer systems can not his usefulness of double as enterprise be no small investment.If a cover computer system can be printed the VAT invoice of a plurality of tax-cards, just can make the shared cover computer system of a plurality of enterprises, significantly reduce the investment of enterprise, help popularizing and promoting of tax-card.
But can there be resource contention in the mainboard of a present computing machine, the tax-card cisco unity malfunction when inserting two or two above tax-cards simultaneously.Therefore a computing machine will use a plurality of tax-cards can only change card one by one, when using another tax-card, opens computer host box that is:, pulls up a last tax-card from the ISA slot, the tax-card that insertion will be used.This has caused great inconvenience to the user, and often open computer host box, removable card can very fast damage computing machine, this is impracticable in actual use.
The purpose of this utility model is the deficiency at the prior art existence, a kind of multi-user's antifakery tax-card divider is provided, adopt time-sharing multiplexing technology, an ISA slot on the computer motherboard is extended to a plurality of ISA slots, a plurality of tax-cards are inserted in these expansions ISA slot, computing machine can timesharing uses the tax-card in any one slot wherein, control which tax-card work by divider, concerning the user,, can in a plurality of cards, select arbitrarily as a selector switch is arranged.This just can make the shared cover computer system of a plurality of enterprises use tax-card, and needn't open computer host box, removable card, realizes a tractor serves several purposes.
The purpose of this utility model is achieved through the following technical solutions: a kind of multi-user's antifakery tax-card divider, comprise: the ISA slot of plug-in mounting tax-card, it is characterized in that: have an ISA driver card that can be inserted in the Computer I SA slot to be connected with lead with an ISA adapter, be connected with the multidiameter option switch circuit between the ISA slot of ISA adapter and a plurality of plug-in mounting tax-cards, be connected with the multidiameter option switch circuit between a plurality of IC-card sockets corresponding and the public IC-card input device with the ISA slot of a plurality of plug-in mounting tax-cards.
The control signal port of described multidiameter option switch circuit is connected to the signal output port of control circuit, and the signal input port of control circuit is connected to the output port of the operation keyboard that includes tax card selection key.
Each control signal port of described multidiameter option switch circuit also can be directly and the operation keyboard control signal port that the card selection key provided of paying taxes connect one to one.
One one-chip computer is arranged in the described control circuit.
Button on the described operation keyboard is the interlocking button.
The ISA slot of described ISA adapter, multidiameter option switch circuit, a plurality of plug-in mounting tax-cards, a plurality of IC-card socket, control circuit are installed in a tax card and share on the mainboard, and the tax card is shared mainboard and is installed in cabinet inside, and operation keyboard is installed on the cabinet.
When bringing into use, the ISA driver card is inserted the ISA slot of computing machine, with lead ISA driver card and ISA adapter are coupled together, insert tax-card in the tax card is shared the ISA slot of each the plug-in mounting tax-card on the mainboard, the numbering of selection key is consistent on its numbering and the operation keyboard.Each later on the use as long as turn on the power switch on operation keyboard, the numbering that clicks selected tax card is just passable.The control circuit that the tax card is shared on the mainboard will send corresponding signal controlling multidiameter option switch circuit according to the numbering of button automatically, need with tax-card switch on the computing machine, simultaneously public IC-card input device card is switched on the corresponding tax-card.
The utility model compared with prior art has many advantages and good effect: ISA slot and a plurality of IC-card socket of drawing a plurality of plug-in mounting tax-cards because of a cover computer system, realized the shared cover computer system use tax-card of a plurality of enterprises, and needn't open computer host box, removable card, the user can pass through the switching and the work of Keyboard Control tax card and IC-card input device easily, as same Individual Income Tax card takies a computing machine separately, function is unaffected, and the utility model is simple in structure, cost is lower, be easy to make, easy to install, fundamentally alleviate the burden of enterprise, helped popularizing and promoting of tax-card.
