Abstract

The utility model relates to a computerized apparatus capable of printing the double sides of directly posted letters. The utility model provided with two printing heads can simultaneously print needed information on the front and the back sides of a piece of printing paper via computer software when the printing paper continuously goes through a printer. The utility model can continuously print a plurality of letters which can be directly posted and be suitable for posting large quantity of bills and letters inbanks, telephone offices, gas companies, etc.

Description

Computerized double-sided printing apparatus capable of directly posting letter

The utility model relates to a kind of computer duplex printer.

At present, personal computer and software are widely used in word processing and data acquisition, and the format corresponding output print in back, but in some occasion: in the time of need sending document in a large number as bank's mailing credit card statement of account, telephone office's mailing telephone charge bill, tap water, Gas Company etc., can't all handle with computing machine, feasible heavy with upper portion door work, be prone to mistake, can not give notice as scheduled.

The purpose of this utility model is to overcome the deficiency of above-mentioned known technology, thereby a kind of letter double-side impact printing device is provided, but the letter that this device prints direct mail after treatment.

The purpose of this utility model is finished in the following way:

Have two printheads (2) and (4) on the printer of this device, wherein, have a pair of pressure roller (5) in the printer, plain pape passes in the middle of printhead rubber roll (3) and printhead (4) through pressure roller, picking up the paper switch through one again passes between printhead rubber roll (1) and the printhead (2), arrive tape puller (7), the printer paper of process duplex printing passes outside the printer again.

Principle of work is: utilize printer and special software, when printer paper passes through printer continuously, print various information needed simultaneously on the positive and negative two sides of printer paper.

The utility model is compared with prior art: mail and envelope are integrated, many envelope letters can be realized continuous printing, the various bills of being sent out for bank, telephone office, tap water, Gas Company etc., all finish by computing machine, alleviate the labour intensity of all departments, improve accuracy rate greatly, thereby increase work efficiency.

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

Fig. 1 is the utility model structural drawing

In Fig. 1: (1) printhead rubber roll; (2) printhead; (3) printhead rubber roll; (4) printhead; (5) pressure roller; (6) pick up the paper switch; (7) tape puller.

Printing portion is made of two rubber roll and two printheads in different directions that abut against together, advance along given line by paper injection road assurance paper, in traveling process, printhead (2), (4) print required content respectively at the tow sides of printer paper respectively, the paper advance mechanism that this printer also has a cover to be made up of gearing and control circuit, this mechanism guarantees that continuous paper is synchronous fully on the relative paper feed position of two printheads, two printheads have separately that independent driving circuits and printhead move control circuit, independently finish the print out task of data separately.

The multi-way switch of control circuit is finished following work according to computer instruction: print data is sent to: 1) printhead (2); 2) printhead (4); 3) be sent to two printheads simultaneously; Be responsible for the anti-computing machine of sending back to of the state of printer; The gauge tap signal is sent to the paper feed control-signals generator.

The paper feed control-signals generator is according to two current print states of printhead, decision sends the correct opportunity of the drive pulse signal of paper feed stepper motor, thereby guarantee when two printheads are not printed, to carry out paper feed, to guarantee that also any printhead is after delegation is finished in printing, not finishing at another printhead can not paper feed before printing, can not print second row, in order to avoid two row contents are printed on in the delegation.

The envelope front of printing prints postcode frame boxes and other for information about in advance, reverse side prints blank bill and relevant explanation item in advance, during through duplex printer, by the computer control printer mailing address in front and the bill content unification of reverse side are printed, after printing is finished, envelope is resolved into unit length one by one along the line of cut of reserving, three edges at reverse side apply glue, sticking wearing after the doubling, again both sides paper feed pore area is cut, just form the shandardized envelope that directly to drop.

Claims

But 1, a kind of device of computer duplex printing direct mail letter, it is characterized in that having on the printer two printheads (2) and (4), printer paper is stained with paper feeding when advancing in printer, in the middle of printhead rubber roll (3) and printhead (4), pass earlier, pass between printhead rubber roll (1) and the printhead (2) through associating again, arrive tape puller (7), pass outside the printer again through the printer paper behind the duplex printing.
2, letter shaped device, the letter of finishing behind the duplex printing installs aftershaping through this, and the continuous paper that this device will be printed resolves into unit length, again with unit length paper doubling and bonding, the paper feed pore area at letter two ends is cut.
