Description

Computer typewriter fingering learning machine

The utility model relates to a kind of computer typewriter fingering learning machine, is meant especially a kind ofly to carry slim and graceful convenience, and is not subjected to the learning machine of the fingering that practices at typing of regional restriction.

Beginner for computer, for making its when operation handy, just in accordance with the wish, which button the placement location of its finger and which finger fixedly are pushed all must be quite skilled, and when its input character, whether the literal that need watch attentively on the computer screen is correct like this, and must not watch the button position of this literal on the keyboard more on one side attentively, on one side must notice also whether the literal of being got is correct, reducing the time that the user is spent when the literal input operation, and increase its text input speed.

The beginner must directly use on the machine when exercise keyboard operation fingering, so that under the cooperation of main frame, display, keyboard and the program of computer, can make the fingering of the skilled at short notice literal input of beginner.Yet because main frame, display, the keyboard volume of computer are quite huge, weight is also heavier, adds power supply, does not move so computer is fit to resettlement, says nothing of certainly and has carried.Therefore, the beginner can only be at computer fixed placement place (as computer classroom, family ...) could learn to use.Though, but the notebook computer of existing out using is being sold on the market, and its price non-masses can accept, and the configuration of its keyboard and button also has a great difference with the general standard keyboard, is not suitable for the beginner.Therefore, usually the beginner is when the study typewriting, the keyboard planimetric map (or typewriting plate) (referring to Fig. 6) of an analogue computer keyboard carries in big city, just can learn fingering on the table and practise so that be placed in random place, but, when doing this exercise, because of having lacked the authenticity of practical operation when participating in the cintest and literal demonstration, so on actual learning defectiveness inconvenience still.

The purpose of this utility model provides a kind of computer typewriter fingering learning machine, and this device can be gone out easy to carry for the beginner, is not subjected to zone and power limitations during use, and price also can be popular acceptance.

Another purpose of the present utility model provides a kind of computer typewriter fingering learning machine, this device by with general standard computor-keyboard specification and all identical keypad portion of size, the screen area that the typewriting exerciser of cooperation internal key can directly be connected with in one shows indication literal and exercise literal, and can show wrongly written character and alarm call takes place, make the user time just can be familiar with general computor-keyboard in exercise, can not cause in study with the real computer of practical operation has obstacle in the adaptation.

The utility model is achieved in that and includes a loam cake, is provided with the relative hollow out through hole of key arrangement on a plurality of cooperation keypad portion at its leading portion; A keypad portion, its button and general standard keyboard aligned identical, size are provided with printed circuit board (PCB) in its pedestal lower end, and are connected with the process of signal transmission circuit board, a base, its covers corresponding with loam cake; It is characterized in that: loam cake back segment be the shape and being provided with of being inclined upwardly for display screen ccontaining form; This display screen utilizes lead to be connected with the word processing circuit board, and CPU, ROM, the RAM device of the button input signal that can handle on the keyboard is housed on this word processing circuit board, and its output terminal is connected with display screen; Can make comparisons with the learning text that display screen shows and consist of that a kind of keyboard is connected with the display screen one and do not need the computer typewriter fingering learning machine of host computer and large screen display.

Display screen wherein is suitable liquid crystal (LCD) display screen of size, can show prompting row, exercise row and the alarm row of reference on display screen at least, links to each other but produce circuit board in its periphery nationality lead and word processing in the circuit substrate.

Wherein can be provided with the battery case of placing battery on this learning machine, and direct supply is provided.

Wherein ac power plug can be provided with on this learning machine,, the mains ac power supply can be directly used so that when indoor use.

Can a solar cell template be set correspondence at last cover frame portion place, the power supply of learning machine is provided so that can utilize sun power to convert thereof into electric energy.

Advantage of the present utility model is many: 1, it is moulded and weight is quite light and handy, and is going out to carry and remove when moving the position, quite convenient.2, because of it is convenient for carrying, so it all is not subjected to region limits in opportunity, the place of using.3, it is complicated just like that the incident of handling because of this device does not resemble common computer, thus many huge processing units need not arranged, so less expensive, easily accepted by popular.4, its keyboard is all identical with the QWERTY keyboard specification and the size of general computer, can be familiar with and the computation identical operations when the exercise fingering, can make the beginner be easy to enter the practical operation of computer and the situation that can not produce maladjustment.

Following conjunction with figs. describes the utility model in detail.
