Description

A kind of multifunctional calculator

Technical field

The utility model relates to accounting supplies technical field, is specifically related to a kind of multifunctional calculator.

Background technology

Counter, generally by arithmetical unit, controller, storer, keyboard, display, power supply and some optional peripherals and electronic components, consists of artificial or machinery and equipment.Arithmetical unit, the controller of low-grade counter realize simple serial arithmetic by DLC (digital logic circuit), and its random access memory only has one, two unit, store for cumulative.High-grade counter realizes various complex calculations program by microprocessor and ROM (read-only memory), has more random memory unit to deposit loading routine and data.Keyboard is the input block of counter, general employing contact or sensor-type.For reducing the size of counter, a key usually has several functions.Display is the output block of counter, has light emitting diode indicator or liquid crystal display etc.Except display result of calculation, also often have and overflow instruction, mistake instruction etc.Counter power acquisition a-c transducer or battery, battery available alternate converter or solar converter recharge.For saving electric energy, the large scale integrated circuit (see complementary metal-oxide-semiconductor integrated circuit) that counter all adopts CMOS technology to make, and timing inoperation automatic power-off circuit is housed in inside.The available peripherals of counter has mini-printer, magnetic tape cassette equipment and magnetic card machine etc.

Modern counter is power with electric power, and has various shape and the sizes such as the specific calculations device from cheap, credit card sized simple machine to attached printing function.

In some commercial situations, people are when calculating price, and the screen of counter is too little, and client cannot intuitively arrive commodity price, and counter is always hand held, very inconvenience.

Summary of the invention

The purpose of this utility model is defect for prior art and deficiency, provides the multifunctional calculator that a kind of structure is simple, reasonable in design, easy to use.

For achieving the above object, the technical solution adopted in the utility model is: it comprises counter body, the first screen, button, rotating disk, support, the second screen, screen seat; The top of described counter body is provided with the first screen, and the top of the first screen is provided with screen seat, and the below of the first screen is provided with button; The bottom of described counter body is provided with rotating disk; Described screen seat is connected with support, and pedestal upper end is connected with the second screen.

As preferably, in described support, be provided with rechargeable battery.

As preferably, the ratio of the length of the second described screen and the length of the first screen is 2 ~ 3.

During the utility model operation, as required, the second screen above counter body and counter body can be rotated on the table by rotating disk, and result of calculation can be amplified on the second screen.

After adopting said structure, the beneficial effect that the utility model produces is: a kind of multifunctional calculator described in the utility model, can rotate, without the need to hand held, and client intuitively can arrive the result that counter calculates, the utility model have structure simple, arrange rationally, the advantage such as cost of manufacture is low.
