Description

Digital facsimile apparatus

One, technical field

The utility model relates to a kind of digital facsimile apparatus.

Two, background technology

Facsimile machine is one of communication tool indispensable in the commercial activity.Facsimile machine is since being born, and the application widely that obtains particularly at commercial field, becomes one of communication tool indispensable in the commercial activity.Even in today of network fast development, facsimile machine still plays irreplaceable effect with the visuality of promptness, the particularly information of the simplicity of its adaptability, operation widely, information in people's live and work, be one of communication tool indispensable in the commercial activity.The irreplaceability of faxing as can be seen from above numeral, but along with Internet development is popularized, the use of Common Facsimile Machine has been subjected to certain influence.On the other hand, along with user's instructions for use is various day by day, common fax can not satisfy user's requirement.Along with development of Communication Technique, facsimile machine also absorbing and adopting the advanced communication technology, to enrich, to improve self function, adapts to the new market demand.And traditional PSTN (full name Public Switched Telephone Network, mean traditional telephone-switching network, being the present the most universal telephone network in the whole world) facsimile machine all is analog signal in the input and output of facsimile data, when scanning output, facsimile machine deposits the facsimile image data encoding process in memory, becomes analog signal to deliver to PSTN data-modulated according to setting simultaneously and carries out the telephone wire mass transport on the net; During input, also be the analog signal on the telephone wire that imports into by the PSTN net, can print through reverse process.

Therefore, there is following shortcoming in common fax:

1, the fax definition is low.Because Common Facsimile Machine adopts telephone wire to transmit, the speed of its transmitting facsimile is generally 9600bps, and flank speed is 14400bps at present.On the other hand, the data volume of high definition fax is bigger, so, realize that on telephone wire the practicality of high definition fax is bad.The scanning density of present most of facsimile machines is 7.7 lines/mm can only transmit the file of big font, if send the fax paper of small font, also have 15.The facsimile machine of 4 lines/mm, but all fundamentally do not solve quality of reception problem, the definition of receiving faxes can't further improve.The progression of three kinds of halftonings of facsimile machine 16,32,64 also can only satisfy generic-document and digital form in addition, and is just poor for the fax definition of picture or photo.

2, the length consuming time of faxing.Common facsimile transmission speed all is 9600bps, is generally facsimile transmission or reception one page A4 fax more than 15 seconds, and can't intuitively understands the other side's accepting state.

3, fax cost height.The great number telephone expenses of strange land fax are high, even the use of IP phone is arranged at present, but also can't be from reducing communications cost in essence; For a large amount of long-distance and mass-sending faxes, then waste great number telephone expenses and consumptive material simultaneously.

4, can't realize colour facsimile.Tradition is faxed because the data volume of high definition fax and colour facsimile is bigger, the transmission speed of common PSTN, and restrictions such as the error rate are used to generally realize that black and white receives, and can not satisfy the requirement of color transmission.

5, fax efficient is low.When same data will send to a plurality of destination, must the repetitive manual dialing, waste time and energy, run into subscriber engaged, more need patience and repeatedly redial repeatedly, the efficient of faxing is low.

Three, utility model content

The utility model has solved that the fax definition that common fax exists in the background technology is low, the length consuming time of faxing, fax cost height, can't realize colour facsimile and the inefficient technical problem of faxing.

Technical solution of the present utility model is: the utility model comprises fax chip 8, contribution scanner 1, guidance panel circuit 3, paper advance mechanism 4, power circuit 5 and PSTN circuit 7, contribution scanner 1, guidance panel circuit 3, paper advance mechanism 4, power circuit 5 and PSTN circuit 7 join with fax chip 8 respectively, its special character is: the described fax chip 8 outer digital interfaces 9 that also are connected to, digital interface 9 comprises central processing unit 11, memory 13 and network interface 10,

fax chip

The aforesaid operations panel circuit 3 outer liquid crystal display circuits 2 that also are connected to.

Above-mentioned fax chip 8 outer TPH (thermal head) print circuits 6 that also are connected to.

The utility model is when scanning output, after facsimile machine deposits the facsimile image data encoding process in memory, through digital coding, be transferred to professional digital fax net by the Ethernet digital interface again, thereby original facsimile data is delivered to objective, when input, neither import analog signal into by the PSTN net, but obtain oneself digital fax file at any time by digital interface, therefore the utlity model has following advantage:

1, fax definition height.The utility model replaces common fax with digital fax, and its transmission means has become advanced Digital Transmission from the analogue transmission in past, promptly can be connected on the present the Internet to communicate, so it can further improve the definition of fax.

2, the weak point consuming time of faxing.The utility model replaces common fax with digital fax, has improved transmission speed greatly, has further shortened the fax time.

3, the fax cost is low.The utility model is to realize fax by network, greatly reduces the long distance communication expense of fax, has reduced the fax cost.

4, can realize colour facsimile.The utility model is realized replacing the ordinary telephone line fax with Network Transmission, but data quantity transmitted increase greatly, can realize colour facsimile.

5, fax efficient height.The utility model can be sent to different addresses simultaneously with same data, and promptly it can realize machine fax time the multimachine, has improved fax efficient.
