Embodiment
As shown in Figure 1, a kind of mini financial keypad that the utility model provides comprises casing 1, button 2, display screen 3 and is encapsulated in the integrated circuit (IC) chip of casing inside, and described button 2 and display screen 3 are arranged on the surface of described casing 1.
Described button 2 is set to 4 * 5 matrix keyboards, and " 0 " key left side interpolation " Esc " key in the lower left corner i.e. " ESC Escape "; Increase namely backspace key of " ← " key being arranged above and below between "+" key and enter key, " Num Lock " key in common keypad is replaced with Menu key " M ".This setup has guaranteed that the financial keypad profile of using in the utility model and reality is basic identical, has suitably expanded again the function of existing keyboard, the purpose of using to adapt to independent exercise.As shown in Figure 2, be the contrast schematic diagram of keyboard of the present utility model and common computer keypad.
Mini financial keypad of the present utility model, described display screen comprise data and the actual display screen of inputting data that demonstration will be inputted, and described display screen is LCD display preferably.
As shown in Figure 3, described integrated circuit (IC) chip comprises CPU, power supply, hummer and pilot lamp, and described CPU connects respectively button, display screen and power supply, and it is CPU and display screen power supply that the power supply of integrated circuit (IC) chip inside connects described CPU.Described CPU is the MCS8051 single-chip microcomputer preferably.
Described mini financial keypad preferably can also comprise the storage unit that is connected on described CPU, is used for data and the actual data of inputting that storage will be inputted.Described mini financial keypad also comprises the data-interface that connects with described CPU, the actual input data of storing in described storage unit can be derived.For example can be by described financial keypad input performance data, described CPU stores the performance input of input into described storage unit, further can the performance data in described storage unit be derived by described data-interface.Described data-interface can be USB interface.
Its course of work is: the utility model can provide the approach of a training and operation to the financial staff.Press menu M key, the display screen the first row shows a mathematics formula, and the operator is as long as input this formula again one time with keyboard and by enter key, the second row of display screen will show this formula, and described CPU judges whether result of calculation is correct.If the operator inputs correctly, so just pass through, display screen shows next formula, the operator can continue exercise; If input wrongly, result is incorrect, and described CPU is to described pilot lamp and hummer transmitted signal, and described pilot lamp sends out a warning, and described hummer sounds the alarm, and display screen continues to wait for user's input.
