Abstract

A printer with scanning function utilizes the movement of web-feeding reel or printing head of the printer to realize the vertical motion of scanning light spot, and implements auxiliary scanning; uses the photoelectric scanning head to realize the horiontal motion of scanning light spot, and can implement host scanning; uses the electric liaison of printer with computer and dependens on the control of computer software to realize the transfer of scanned data, i.e. data write-in. The printer has dual functions of printing and scanning, low cost and convenient use, and on combination with FAX/MODEM, can realize the transfer of colour information data.

Description

A kind of printer of tool scan function

The present invention relates to a kind of improvement of printer, specifically, is the printer that two kinds of functions were printed and scanned to a kind of tool.

Commercially available printer, it is only as the peripheral output device of computing machine, the i.e. function printed of tool, it accepts the control of computing machine, follow procedure is printed as literal or pattern with the output data of computing machine, conversely, processes processing if literal or pattern are sent into computing machine, then printer is powerless, can only lean on the input media of scanner and so on to finish.Particularly, along with the appearance of low price FAX/MODEM card, make and calculate transmission and the reception that function is conveniently used in graph text information.Yet, this graph text information sending/receiving system of forming by computing machine, printer, FAX/MODEM card and scanner, not only take usage space, but also be that the scanner that uses at present is not the inconvenience (hand-held scanner is had relatively high expectations to translational speed) that (flatbed scanner) just be to use that costs an arm and a leg, practicality is not strong, is difficult to satisfy widely used requirement.

The object of the present invention is to provide a kind of printer with printing and scan function.

Technical scheme of the present invention is: 1, utilize the motion of coil paper cylinder on the printer or printhead realize scanning spot vertically to moving, promptly realize subscan; 2, the level that the scanner head on the existing scanner of utilization is realized scanning spot is promptly implemented main sweep to moving; 3, utilize the circuit of existing printer and computing machine to connect, rely on computer software control, the data that realize scanning transmit, and promptly data write, therefore, printer of the present invention, tie up on the appropriate location outside the coil paper cylinder of printer scanner head (optical system) is installed, it connects with circuit mutually with computing machine: corresponding to printing type, data are exported by computing machine; Corresponding to scan mode, number tool input computing machine.

Advantage of the present invention is: 1, and make printer have the double action of printing and scanning, reduce cost significantly and reduced placement space, and convenient the use; 2, combine with FAX/MODEM, can realize the chromatic information data transfer of computer network, i.e. colour facsimile, this is the function that existing facsimile recorder can't have.

The present invention is implemented by the following drawings:

Fig. 1 is a mechanical schematic diagram of the present invention

Fig. 2 is that scanning information of the present invention transmits electrical schematic diagram

Fig. 3 is the embodiments of the invention synoptic diagram

Fig. 4 is the another embodiment of the present invention synoptic diagram

Below we will provide two better embodiment of the present invention according to Fig. 1～Fig. 4, and, further provide ins and outs of the present invention in conjunction with to the description of embodiment.

Embodiment 1, and present embodiment is provided by Fig. 1～Fig. 3.

See also Fig. 1, as shown in the figure, scanning object 2 (the paper spare that has figure and literal or picture and text to mix mutually) is that the chart drum 3 by printer drives, and optical system 1 produces retouches luminous point, connects with light with object 2.

See also Fig. 2, as shown in the figure, printer is connected with computing machine through printing cable 24, printer interface 5, data controlling signal line 6, I/O conversion control circuit and decoding (decoding) device 7, print control signal line 8, line of a printer 9, printing control circuit 10, movable machinery control signal wire 11, movable machinery control circuit 12, scan control signal line 13, scan-data line 14, control circuit 15 and other signal wire 16, other signal control circuit 17.

See also Fig. 3, the optical system of present embodiment is the hand-held scanner machine, and it is fixed with printhead 18 by the trip bolt on attachment screw 21 and the printhead 19 by web member 20 and connects.Adjust on this hand pulling type scanning machine each switch to desired location, scanning object 2 passes through the scanning window of hand-held scanner machine just by the reference position of coil paper cylinder 3 objects that scrolling scans 2.Start computing machine, the driver of operation hand-held scanner scans and writes.When printer was in print state, then the computer starting print routine was implemented printing function, and promptly facsimile message is printed or accepted to sense data.

Embodiment 2, realize according to Fig. 1, Fig. 2 and Fig. 4.

See also Fig. 4, optical system 1 is the hand-held scanner machine, and it is installed on the printing head 18, subscan, and promptly vertical scanning drives hand-held scanner by printhead 18 and finishes with respect to scanning object 2; Main sweep (horizontal scanning) is finished by this hand-held scanner.As shown in the figure, this hand-held scanner, i.e. optical system 1 and embodiment 1 identical being installed on the printhead 18, but subscan is controlled printhead 18 by computer program, drags hand-held scanner, presses the standard scan speed motion of hand-held scanner.Scanning backing plate 22 is held plate 23 with paper delivery and is fixed together among the figure, makes scanning object 2 just hold between the plate 23 by hand-held scanner and paper delivery, and is close to paper delivery and holds plate 23.

At last, we will point out that also the optical system among Fig. 1 also can be installed on printer roll paper tube other appropriate location in addition, as long as the scanning spot of optical system 1 is focused on the scanning object 2, scanning object 2 is driven by coil paper cylinder 3.

Claims

1, a kind of printer of tool scan function, it is characterized in that on chart drum (3) appropriate location in addition at printer scanning optics (1) being installed, optical system (1) becomes optical link with the scanning object (2) that is driven by coil paper cylinder (3), and the printing/scan function of printer is by computer control.

2, printer according to claim 1 is characterized in that optical system (1) is a hand-held scanner machine.
