Abstract

The utility model relates to an electronic name card holder. In the utility model, a plastic housing covers an inner core, and the inner core is mainly composed of a single-chip microprocessor, an ROM, an RAM, a power managing circuit, an interface circuit for infrared communication, an interface circuit for audio communication, a loudspeaker and a microphone. The utility model has the advantage that the circuit of the utility model is simple and smart, the cost is low, the utility model is convenient in generalization, and the utility model is portable; the utility model can store lots of name card information, and the utility model can conduct short-distance or long-distance (by a telephone line) message switching with the other electronic name card holder by an infrared communication interface and an audio communication interface; the utility model can fully substitute for the traditional name card, and the inconvenience of printing, carrying and switching existing of the traditional name card is removed.

Description

Electronic visiting card scanner

The utility model relates to electronic technology field, relates in particular to a kind of being convenient to and carries, the electronic visiting card scanner that can store and exchange card information.

Traditional business card generally is that Word message is printed onto on the paper carrier, when information such as needs exchange name, phone, address, then paper carrier is intercoursed.

The deficiencies in the prior art are, along with exchange capacity increases, and the inconvenience that certainly will cause business card to carry and consult.

Goal of the invention of the present utility model is exactly fundamentally to overcome above-mentioned deficiency, designs a kind of volume I and carries, and can store a large amount of card informations, and can carry out the novel electron cards folder of message exchange.

The utility model is realized its goal of the invention by following technical solution:

Complete machine is carried based on small and exquisite being convenient to, and can be thin as notebook type, and suitable coat pocket is deposited, and also can be that the beeper formula hangs on the waistband.

Plastic casing is wrapped in inner core, its inner core mainly is made of chip microprocessor, ROM, RAM, electric power management circuit, infrared communication interface circuit, voice communication interface circuit, loudspeaker and microphone, there are LCD and keyboard in the front, the back side is battery case, microphone and speaker openings, and there is infrared/receiving port the side.

This device is the control core with the single-chip microcomputer, and all functions realize by Single-chip Controlling.

This device is battery-powered, and volume is urinated in carrying, and utilizes electric power management circuit to make its power consumption near minimum, standby current≤2mA.

Utilize the infrared communication interface circuit, can carry out closely the message exchange of (for example in the 10M) with another electronic visiting card scanner; Also can carry out data storage, printing with the computing machine with infrared interface, printer.

Utilize the voice communication interface circuit to produce the sound of one or more characteristic frequency,, information is reached another electronic visiting card scanner of far-end by telephone wire by the microphone of telephone set.Another electronic business card of far-end utilizes this interface circuit after being clipped in the sound that receives the characteristic frequency that the telephone set loudspeaker transmits, and converts the discernible level signal of single-chip microcomputer to, thereby finishes the message exchange of far-end.In this process, environmental noise on every side can not disturb proper communication.

Infrared communication and voice communication mode all adopt check code, the bit error rate less than 100,000/.

Utilize the voice communication interface circuit can produce touch-tone signal, automatically the telephone number on the required business card is transferred to when making a phone call, easy to use.

Below in conjunction with drawings and Examples the utility model is further elaborated:

Fig. 1 is the structural form synoptic diagram of an embodiment of electronic visiting card scanner.

Fig. 2 is the application structure synoptic diagram of an embodiment of electronic visiting card scanner.

Fig. 3 is single-chip microcomputer and other parts connection status synoptic diagram among the embodiment of electronic visiting card scanner.

Among the figure, the 1st, plastic casing, the 2nd, LCD, the 3rd, keyboard, the 4, the 5th, infrared/receiving interface, the 6th, battery case, the 7th, battery, the 8th, loudspeaker, the 9th, microphone, the 10th, single-chip microcomputer, the 11st, ROM, the 12nd, RAM, the 13rd, electric power management circuit, the 14th, voice communication interface.

(embodiment)

Single-chip microcomputer 10 adopts MC68HC05L, and maximum can extend out the 20M storer, is used for depositing the coded message of Chinese character font and input method of Chinese character.

Keyboard 3 is provided with 26 letter keys, ten key and function keys.

LCD 2 adopts 122 * 32 dot matrix, can show 2 row Chinese characters.

Infrared communication interface circuit 4,5 adopts infrared to receive pipe, respectively links to each other with single-chip microcomputer by a current-limiting resistance, is responsible for encoding and decoding by single-chip microcomputer.

Voice communication interface circuit 14 can adopt dual-tone multifrequency to send and receiving circuit MT8880 and discharge circuit LM324, to simplify hardware design.

Electric power management circuit 13 adopts MC1413 and MC34164, and MC1413 powers to peripheral circuit by Single-chip Controlling, and MC34164 provides the low pressure warning signal to single-chip microcomputer.

The utility model has the advantages that: the simple volume of circuit is small and exquisite, and with low cost being convenient to promoted, Be suitable for carrying, can store a large amount of card informations, utilize infrared communication interface and audio frequency Communication interface can be carried out closely with another electronic visiting card scanner or remote information exchange, Conventional business card can be substituted fully, the inconvenience of removed the conventional business card printing from, carrying, exchange.
