Description

Multifunction Device Using Shuttle Original Reading Means

The present invention relates to a multifunction printer, and more particularly, to mount an inkjet printing means and a shuttle document reading means on different axes in a multifunction device which transfers an original and the chloroplast transfer through the same transfer path using an inkjet printing apparatus. The present invention relates to a multifunction apparatus using shuttle document reading means for reciprocating an inkjet printing means and a shuttle original reading means and performing original reading / printing by driving by connecting to one power means.

First of all, the above-mentioned Locused body referred to herein refers to a recorded object such as printing paper.

Today, office automation (OA) devices such as printers, scanners, and fax machines are widely used. Each office automation device is being developed at high performance to expand its unique capabilities, resulting in more expensive products. On the other hand, by developing each of the office automation equipment that was used independently as a single product has been produced to reduce the economic burden on the user. Such a device is generally called a multifunction device.

In general, since the multifunction printer includes a separate document reading device and a separate printing device, the reading and printing of the document were performed using the reading device and the printing device in the multifunction printer.

Therefore, such a composite apparatus required a drive motor for document transfer, a carriage motor for the left and right reciprocating motion of an inkjet print head which is an image forming apparatus, and the above-described rotator transfer motor, respectively.

Also, image data can be digitally read through an intermediate image reduction mirror using a fixed CIS (Contact Image Sensor) image sensor or a fixed CCD (Charge Controlled Device). Originals were read using a converting method.

Hereinafter, the operation of a general multifunction device having the above-described structure and features will be described below.

When the original is to be read and the data stored in the memory is to be printed, the original document is placed in the document input unit of the scanner located at the top of the printing apparatus, and then the original condition is detected by the document presence sensor.

After the original condition is detected, the document feed motor is driven according to the command of the central processing unit, and at the same time, the documents located between the pickup roller and the friction pad are picked up one by one due to the frictional force difference.

The picked originals are transferred to the original reading unit, and the original reading unit fixed to the base of the original scanner is prepared to read the originals by a regi-sensor indicating the status of the original entry position.

At this time, after a certain time has passed after confirming the other party's fax number transmission or by using the user's control key to instruct copying, the document reaches the document reader and at the same time the CCD or CIS The image sensor will read the original.

Through this process, when the document is moved out of the output sensor by the document feed motor and feed rollers, the document feed motor stops after a certain time, and the data read by the document reader is converted into digital data and stored in the memory. In this case, the modem and the line interface unit are used to transmit to a predetermined device (for example, a printer device).

When printing the read data, the digital data is transmitted to the printing apparatus via a central processing unit to perform data printing.

On the other hand, the shuttle type inkjet printer, which is one of the printing apparatuses, receives a print command by the central processing unit and the controller to print data transmitted from the outside, and then picks up the recording medium in the recording storage cassette by the rock-body transfer motor. Picks up.

Subsequently, power is transmitted to the shaft by a power changer installed on the ledge roller shaft after activating the ledge-sensor and forming a certain amount of loop between the stopped Regi-Roller Nip. At this time, a clutch may be used as the power switching device.

The recording body conveying motor is stopped after entering the predetermined position of the print area of the inkjet print head which is the image forming body.

At this time, when the data to be printed is sent from the central processing unit to the inkjet head driver as a controller, the head driver supplies electrical energy to the ejection position of the print head so that an image is formed at a predetermined position, and transfers the print head mounted on the carriage assembler to the green body. When a certain width of printing is completed while the carriage motor is reciprocated in a direction orthogonal to the direction, the lock body feed motor transfers the lock body by a predetermined length.

Through this method, the printing process corresponding to one sheet of the above-mentioned green body is continuously performed until the rear end of the green body is discharged to the stacker out of the discharge sensor.

The general multifunction device, which operates in this way, consists of an array of document readers for reading the originals, which is expensive in terms of installation area, manufacturing difficulty, and price. In particular, it is arranged in terms of price to commercialize color CIS and CCD. There was a problem of more than tens of times higher.

In addition, an original feed motor for reading an original and a recording medium transfer motor for printing are required, and thus there is a problem in that a separate control device and an installation space and material cost are additionally required.

It is an object of the present invention to read an original through a shuttle of the original reading means, to mount the original reading means on a shaft located at a position separate from the carriage shaft for the reciprocating motion of the printing means, Solving the problems of the prior art by performing the drive using the same power source, not only the simplification of the set, but also the material cost reduction and high-quality data reading by the local read sensor when scanning color documents.

A carriage frame (not shown) for mounting the carriage shaft 12, the shuttle document reading means 11 to perform a fixed and reciprocating motion on the guide carriage shaft 12, and for the reciprocating motion of the carriage frame. A carriage motor 13 for generating power, a belt 14 for transmitting power generated by the carriage motor 13, and storage means for temporarily storing data read by the shuttle document reading means 11; 15, a plurality of conveying rollers 16 for conveying the original, and printing means 17 for printing the original or data to be transmitted to the outside.

Looking at the operation of the present invention shown in Figure 1 as follows.

First, when a document placed on the document table 19 is picked up and reaches the reading means by the document feed roller 16, and then stops, a predetermined length in a direction orthogonal to the document feeding section of the document reading means 11 is stopped. Perform manuscript reading while reciprocating as much as possible.

At this time, the document reading means 11 is mounted on the shuttle carriage assembly (not shown), the shuttle carriage assembly is connected to the guide carriage shaft 12 so that the power generated by the carriage motor 13 is driven by the drive belt 14. When transmitted through the reciprocating motion in the direction orthogonal to the original feed direction.

The shuttle original reading means 11 reads the original in a predetermined width unit every read and transmits the original to the host computer or to the storage means 15 to store the read data.

At this time, the conveyance width of the read document is conveyed by the width of the original to be read by one reciprocating motion, and the original is read by repeating the above process for the original.

In addition, since the read data is transmitted to the printing means 17 and printed, original reading and printing can be performed at the same time.

As mentioned above, the printing means may be an inkjet printer or a laser printer.

2 is a side cross-sectional view cut away from the side of this embodiment of the present invention. As shown, in a multifunction apparatus having a compound function using an inkjet printing apparatus which simultaneously performs reading of an original and printing on the above-described green body (printing paper), the shuttle original reading means 11 for reading the original and the recording for The inkjet print head 25, which is an image forming body, is driven by one carriage motor 26 in a direction orthogonal to the conveying direction of the original and the lock body, and reciprocates.

At this time, the belt 14 and the pulley 27 for driving the reading means 11 are connected to the belt 29 and the pulley 28 for driving the inkjet print head 25 by a power transmission belt 30. Power generated in the carriage motor 26 is transmitted to the shuttle document reading means 11 through the power transmission belt 30 to reciprocate the shuttle document reading means 11.

Therefore, since one carriage motor 26 is driven, the inkjet print head 25 and the shuttle document reading means 11 are simultaneously driven, and the left and right reciprocating motions are carried out in a direction orthogonal to the conveying direction of the original and the chloroplast (printing paper). To read and print the document simultaneously. 3 is a side cross-sectional view showing a cut side of the third embodiment of the present invention. In the multifunction apparatus having a compound function using an inkjet printing apparatus as shown in the drawing, the document reading means 11 is installed below the printing means 25 to transfer the document and the green body with one feed motor (not shown). Are simultaneously performed and the shuttle read carriage 11 is simultaneously reciprocated by one inkjet printhead carriage motor 43.

On the other hand, the device for performing the transfer of the document and the green body at the same time by using a single transfer motor to look through Figure 5 to be described later and looks at the power transmission process through this.

The operation of the multifunction device configured as described above will be described with reference to FIGS. 3 and 4. When the document is placed on the document table 19, the central processing unit drives the feed motor by the document presence sensor 41. At this time, the printing means 25 and the document reading means 11 are driven together by the power transmission means 30.

At this time, if the central processing unit detects the document transfer by the document presence sensor 41, the central processing unit does not operate the power switch for driving the rollers of each unit of the printing means. The leading end of the original is aligned via the 42 and the ledge sensors 43, and the document reading means 11 is notified of the conveyance of the original.

When the user turns on the selection key and start key for copying or fax transmission to a PC, the central processing unit operates the carriage motor 43 after the initial document setting is stopped in the area of the original reading means 11. When driven, power is transferred from the belt 14 of the inkjet print head 25 to the belt 36 of the shuttle read carriage by driving the power transmission belt 30 so that the inkjet print head carriage 25, which is an image forming body, and the document are driven. The document reading means 11 for reading the document is simultaneously driven to reciprocate in the direction perpendicular to the feed direction of the document. In this case, since the document is read by a single reciprocating motion, the document is read by using a feed motor in the direction of the original travel by the predetermined width.

At this time, the carriage motor 43 is a stepping motor driven by the predetermined steps according to the control of the central processing unit to reciprocate the printing means 25 and the reading means 11, and also determined according to the control of the central processing unit. The feed motor which is driven step by step to feed the conveying body is also a step motor.

This document reading operation is repeated until the document feed is completed.

On the other hand, since the read data is converted into a digital signal and transmitted to a memory (not shown), when the data is to be transmitted to the outside, the read data is transmitted to the outside through a line interface and a modem.

In addition, when a document is to be copied, it is transmitted to the printing means by the central processing unit through the controller, and the central processing unit drives the power switching means of the printing means to record the recording body in the cassette 31 for loading the above-mentioned green body (printing paper). Is picked up by the pickup roller 32 one by one, and the recording medium reaches the image forming area of the inkjet print head 25 through alignment and position control of the recording material by the intermediate roller and roller. In this case, the power switching device on the register-roller shaft is turned off so that the recording medium is stopped by the stop of the roller, and ink is transferred to the recording medium at the jetting position of the predetermined print head to form an image at a predetermined position by the head driver. The image is formed by spraying by a predetermined amount.

When the image is formed, it is ejected by the recording medium feed motor, conveyed by the printed width, and then printed again, and the printing is completed when the green body is loaded on the discharge table out of the discharge roller.

In addition, if you want to copy the original, you can print the read data immediately after a certain line, so that you can quickly transfer and copy the original, and perform simultaneous document reading and printing even with a low capacity memory. You can do it.

When such original copying is performed, the original reading length of the original reading means 11 is read in one reciprocating motion and the print head of the printing means 25 can print on the green body. The length can be adjusted to be the same width or multiple times the same width.
