Description

Print scanned controller

The utility model is related to a kind of print scanned controller for being connected between scanning means and printer, being capable of directly print scanned file.

With the improvement of people's routine office work condition, there are the equipment such as printer, computer and scanner in many offices, and operating efficiency is guaranteed to a certain extent.But some files need directly to replicate several parts sometimes, when not having duplicator, people are often difficult to be simply completed this work.Or need, by scanning, file to be first stored in computer, printed again after treatment, computer must not be so not take up；Or have to purchase duplicator.In office equipment, duplicator is a kind of equipment costly, and many offices can not possibly set copier.In addition, general duplicator does not possess the function of color photocopying, when needing to replicate color file, also it could only be carried out using the combination of computer and scanner and printer, therefore duplication could be completed by computer again, for this senior office equipment of computer, this mode is substantially a kind of wasting of resources.

The purpose of this utility model provides a kind of print scanned controller aiming at the deficiency of prior art, when needing to complete to replicate using scanner and printer, it may replace computer, it is connected directly between printer and scanner, the file data replicated the need for having scanned delivers to printer, then prints several parts, and its cost is relatively low, using easy to operate, versatility is stronger.

What the purpose of this utility model was realized in：A kind of print scanned controller, its input interface connects scanner output end, and output interface connects printer input.It is by input interface and keyboard connect central processing unit (CPU) input mouth line, CPU outputs mouth line connects output interface and display device is constituted.

Described input interface or output interface can connect CPU mouth lines by I/O expansion interface circuits.

Described input interface, output interface can be to meet the interface of IEEE-1284 standard parallel modes or be the interface of USB (USB) mode.

Understood according to above-mentioned technical proposal analysis, the utility model belongs to a kind of inexpensive but very practical print scanned controller of office automation class, under conditions of no duplicator, or when only needing to replicate several papers in time, using existing scanner and printer, the utility model is connected in the middle of two equipment, it can by the file data scanned by processing send printer to print, and existing office equipment can be taken full advantage of by operating different function keys to imitate the process of general duplicator hard-copy file.And the utility model coordinates color printer especially to complete the reproducting contents such as colour picture, meets different actual demands, this is the function that general duplicator does not possess.

The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.

Fig. 1 is that the utility model constitutes block diagram.

Fig. 2 is the utility model circuit theory diagrams.

Referring to Fig. 1, 2, the utility model is a kind of print scanned controller, it meets IEEE-1284 standards or EPP standards, I/O expansion interface circuits I (81C55) PA0-PA7 can be met as the input interface circuit I of parallel port access way AD0-AD7, interface circuit I WRITE, DATASTB, ADDRSTB, INTR and WAIT meet I/O expansion interface circuits I (81C55) PC0-PC4, the mouth line P20-P27 that I/O expansion interface circuits I (81C55) AD0-AD7 meets CPU completes data exchange, CPU mouth lines P30-P33 connect I/O expansion interface circuits I /WR, the control instruction of/RD and ALE transmission collection input datas.Function keyboard K1-K12 sets CPU state by I/O expansion interface circuits II (81C55) PB0-PB7 mouth lines.CPU mouth lines P34-P37 connect I/O expansion interface circuits II /WR ,/RD ,/CE and the ALE transmission control instructions such as output data, the AD0-AD7 that CPU mouth lines P10-P17 meets I/O expansion interface circuits II carries out data exchange, data output is played output interface circuit II by I/O expansion interface circuits II DA0-DA7, output interface II output port connects printer input port, the output interface can be the interface for meeting IEEE-1284 standards if parallel port mode is connected, then.CPU mouth line P00-P07 meets the DB0-DB7 of LCD display devices, shows adjusting parameter.The PB0-PB3 mouth lines that E1, E2, A0 and R/W control line of LCD display devices meet I/O expansion interface circuits I exchange the display control signal that CPU is sent.I/O expansion interface circuits II PC0-PC4 is met as printer front end output interface circuit II control instruction line WRITE, DATASTB, ADDRSTB, INTR and WAIT.

When using, input interface I input directly connects the output end of scanner, the data of scanning are delivered to CPU by scanner by input interface I, I/O expansion interface circuit I, the data buffer area of the drivers such as printer, character library, instruction, constant, form and movement is equiped with CPU, can calculate, edit, store scan data.Due to the adjustable ratios replicated of K1 in function keyboard, K2 brightness-adjustings, K3 adjusts colourity, K4 sets number, K5 display reminding menus, K6 starts (monochromatic copy function) to be monochromatic, K7 starts (colored copy function) to be colored, K8 is to be incremented by button (completing being incremented by for regulating object), K9 is the button (completing successively decreasing for regulating object) that successively decreases, K10 sets for paper mold, K11 is present apparatus self-inspection button, K12 is present apparatus on/off button, therefore the initial value of CPU each operation can be set by the function key as general duplicator, layout is selected, the display device that CPU is connect can show setting state at any time, the scan data calculated is picked up output interface II by CPU by I/O expansion interface circuits II again, printed again to printer, so as to complete the overall process of duplication.

In view of the operating system of computer is in rapidly more redaction at present, USB (USB) long transmission distance, processing speed are fast, and can 128 ports of band, disclosure satisfy that different actual demands.To coordinate the use of various equipment, input interface I or output interface II can be USB.The connection of the object such as USB and scanner or printer can be serial mode, and it is directly connected with CPU data mouth line and control mouth line.In input, the mouth line P20-P27 that USB AD0-AD7 meets CPU completes data exchange, USB I /WR ,/RD ,/CE and ALE connect the control instructions of CPU mouth lines P30-P33 transmission collection input datas；In delivery outlet, USB II /WR ,/RD ,/CE and ALE connect the control instructions such as CPU mouth lines P34-P37 transmission output datas, the AD0-AD7 that CPU mouth lines P10-P17 meets USB II carries out data exchange.

In addition, the utility model can be combined as a whole with scanner, the scanner so with parameter setting, data-handling capacity is directly connected with printer, you can complete replication work.
