Among the figure: the 1st, touch and load button, the 2nd, functionality buttons, the 3rd, connect computer interface, the 4th, electric source line interface, the 5th, electromagnetic relay, the 6th, central processing unit, the 7th, voice device, the 8th, information-storing device, the 9th, state A, the 10th, state B, the 11st, the button part that touches and import.
Embodiment
The contrast accompanying drawing is described further embodiments of the invention below:
The present invention is that a kind of blind person's special electronic is read and input media, comprise power supply, central processing unit 6 and control knob, also comprise information-storing device 8 and recognition button, described central processing unit 6 links to each other with information-storing device 8, control knob and recognition button respectively.
Fig. 1 is the theory diagram of apparatus of the present invention, comprise central processing unit 6, information-storing device 8, control knob, recognition button, voice device 7, connect computer interface 3 and power supply, control knob is a functionality buttons 2, recognition button is to touch and load button 1, central processing unit 6 links to each other with information-storing device 8, touch and load button 1, functionality buttons 2, voice device 7 respectively, information-storing device 8 also be connected computer interface 3 and link to each other.Central processing unit 6 can be controlled touch and load button 1 projection or non-projection, the energising situation of the electromagnetic relay 5 of control touch just and load button 1, central processing unit 6 can also be handled existing information, be converted to electronic document such as braille, braille converts Chinese character or voice to, and voice device 7 is subjected to the control of central processing unit 6 too.The many contents of information-storing device 8 storages comprise the braille database, braille and Chinese character, voice comparison database etc., and it also can store the e-text of braille or Chinese character.
Fig. 2 is the schematic top plan view of apparatus of the present invention touch and load button, and Fig. 3 is that apparatus of the present invention touch and the master of load button looks perspective diagram.Comprise the button part 11 and the electromagnetic relay 5 that touch and import, under the input state, make the relay path downwards by button is pushed, as state A9, produce electric signal input central processing unit 6, electromagnetic relay 5 carries back-moving spring, button keeps raised position during no acting force, as state B10.Under the read state, corresponding electromagnetic relay 5 work of central processing unit 6 controls by 5 energisings make it produce electromagnetic force to electromagnetic relay, make respective keys overcome spring force and move downward, as state A9, the user discerns by touching the concavo-convex of every group of button.
Form because the minimum character of braille is the point of six triplex rows, two row, so this device is one group by six touches, load buttons, arrangement mode is consistent with braille, use at least one group or more than.
Fig. 4 is the structural representation of apparatus of the present invention, comprise and touch with 1 group of load button, function button, be connected computer interface 3 and electric source line interface 4, functionality buttons 2 comprises reads and imports switch key, input character acknowledgement key, input character cancel key, reading page turning key, the functionality buttons that promptly shows next Braille etc., connecting computer interface 3 can link to each other this device by connecting line with computer, intercourse data, optional USB interface.Device can also be provided with electric source line interface 4, and electric source line interface 4 can connect power lead this device power supply is charged, and certainly, also can select other power mode.
The concrete flow process of using is as follows:
Use the read function flow process: start, by reading and input switch key selection read function, central processing unit 6 is opened the braille electronic document catalogue in information-storing device 8 storages, select corresponding braille electronic document to open, central processing unit 6 is an electric signal with the information translation of braille electronic document, electromagnetic relay 5 work in corresponding touch of control and the load button 1, making respective keys overcome spring force moves downward, the blind person touch by contact and 1 group of load button in the conscientious reading of concavo-convex situation of six buttons, select to read page turning key by function key, promptly show functions such as next Braille, reading finishes and closes the braille electronic document, use and finish, shutdown.
Use the input function flow process: by reading and input switch key selection input function, make electromagnetic relay 5 paths by pushing touch and load button 1, produce electric signal, electric signal is on the same group imported central processing unit 6 respectively, it is the braille electronic document that central processing unit 6 will be put conversion of signals, determine or the cancellation input character by input character acknowledgement key or input character cancel key, select to determine, central processing unit 6 is preserved the braille electronic document of input character, otherwise do not preserve, after the end of input, use the document storing function key, central processing unit 6 deposits the braille electronic document in information-storing device 8.
At last; it is also to be noted that; what more than enumerate only is a specific embodiment of the present invention; obviously; the invention is not restricted to above embodiment; many distortion can also be arranged, and all distortion that those of ordinary skill in the art can directly derive or associate from content disclosed by the invention all should be thought protection scope of the present invention.
