Description

SPECIFICATION Recording apparatus BACKGROUND OF THE INVENTION Field of the Invention This invention relates to a recording apparatus having a function for removing unfixed ink from a recording member on which recording has been carried out (an image has been formed) by the ink jet recording system, and more particularly, to an improved recording apparatus for preparing an original suitable for supplying to an overhead projector (herein after, referred to as "OH P").
Description of the Prior Art In general, transparent resin films such as polyester film, etc. suitable for use as an original for the overhead projector (OHP) have no ink absorbing property and insufficient fixing property of images formed with ink when images are formed on them by the ink jet recording system. As a result, an original for OHP produced by forming an image on transparent resin films has some disadvan tages; namely; such an image is of poor quality and liable to be dislodged from the film.
SUMMARY OF THE INVENTION An aim of the present invention is to pro vide a recording apparatus which can prepare an original suitable for supplying to 0HP having a firmly fixed image of high quality on itself by removing unfixed ink left on the image forming surface of the recording mem ber.
According to the present invention, there is provided a recording apparatus comprising image forming means for forming an image on a recording member by the use of an ink and liquid absorbing means for removing unfixed ink from the recording member on which the image has been formed.
BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a schematic view showing the internal structure of the apparatus according to the present invention.
Fig. 2 is a block diagram showing the control system of the apparatus shown in Fig.
1.
DESCRIPTION OF THE PREFERRED EMBODI MENTS The present invention will hereinafter be described in detail by reference to the draw ings.
Figure 1 shows an embodiment of the multicolor ink jet printer according to the present invention. In Figure 1, reference numeral 1 designates a recording member cassette in which a recording member 2 is packed and 3 designates a paper feeding roller for feeding the recording member 2. The recording member 2 is used as an original for 0HP after images are formd on its surface, as will later be described. Therefore, a transparent resin film is used as the recording member 2. 4 is a registration roller pair and 5 is a transporting roller pair for transporting the recording member 2. 7, 8, 9, 10 and 11 are transporting guides for transporting the recording member 2 smoothly. 6 is a transporting roller for transporting the recording member 2 to which a liquid absorbing roller 1 6 is welded with pressure.The peripheral surface of the liquid absorbing roller 1 6 is coated with porous material such as cloth, paper, sponge or the like (not shown). 1 7 is a squeezing roller, which restores the ink absorbing property of the liquid absorbing roller 1 6 by squeezing out the portion of the ink absorbed from the recording member 2 from the liquid absorbing roller 16. 18 is a recovery tank for the ink squeezed out by the squeezing roller 1 7. 1 2Y, 1 2M, 1 2C and 1 2B are ink jet recording heads for jetting color inks of yellow, magenta, cyan and black onto the recording member 2, respectively, which regenerate and record a color image on the recording member 2 according to an image signal from an imagereading device (not shown).These recording heads are arranged in full-line in the direction meeting at right angles with the transportation direction of the recording member 2, that is, in the direction perpendicular to the drawing sheet. 1 3 is a suction fan and 14 is a porous guide plate. The recording member 2 is attracted to the guide plate 14 by the action of the suction fan 1 3 to maintain eveness of the surface of the recording member 2.On the surface of the recording member 2 thus attracted to the guide plate 14, the ink jet recording is carried out by means of recording heads 12Y, 12M, 12C and 12B. The recording member 2 is then transported to be contact with the liquid absorbing roller 76, and the unfixed ink component remaining on the surface thereof, in particular, the unvaporized solvent and/or wetting agent, is absorbed by the liquid absorbing roller 1 6 to be removed.
Then, the recording member 2 on which the recording has been carried out, the ink has been firmly fixed and the unfixed ink component has been removed, is discharged into a discharge tray 1 5 through a discharging roller pair 19.
It should be explained that the fixation of the coloring material for image formation on a sheet is achieved by causing the solvent in which the coloring material is dispersed or dissolved to permeate into the sheet by capillary action and then to vaporize so as to leave the coloring material in the sheet. In general, recording liquids contain a wetting agent such as glycols, etc. Such wetting agents have poor volality and tend to remain on the surface of the sheet in the form of viscous liquid of relatively low adhesion to the sheet at the tinge of fixing, the colouring material being relatively well adhered, e.g. by the abovementioned permeation. The term "unfixed ink" as used herein will normally comprise mainly this viscous liquid. In the case where a resin film is used as the recording sheet, the same fixation principle as that described above can be applied.However, the surface of the film is treated by the application of a hydrophilic coating since the film has very poor ink absorbing ability.
Figure 2 shows the control system of the apparatus of the present invention. In Figure 2, MPU designates a microprocessor which governs the driving and control of various sections. ROM denotes a read-only memory in which is stored the control program such as the operation procedure. RAM designates a random access memory in which various data are temporally stored. BUS designates a bus which governs the giving and receiving of data and control signals among various sections. OP designates an operation section which appoints and indicates the recording conditions such as the number of recording and the recording image density. etc.Input signals from the operation section OP are supplied to the microprocessor MPU through the peripheral interface adapter PIAI and the bus BUS. 1 2Y. 1 2M. 1 2C and 1 2B designate the above mentioned recording heads, respectively. 41. 42, 43 and 44 denote driving circuits which drive the recording heads 1 2Y.
12M, 1 2C and 12B, respectively. To the driving circuits 41-44, there are supplied, from the image signal output section 45, the image signals corresponding to the image information read by the image reading device (not shown) and are also supplied the driving signals from the microprocessor MPU through the adaptor PIA2. On the basis of these driving signals, the driving circuits 41-44 drive each of the recording heads 12Y, 12M, 1 2C and 1 2B to form an image on the recording member 2 transported from the cassette 1 by using the each color ink as shown in Figure 1.
46 designates a driving motor which drives rollers 3, 6 and roller pairs 4, 5 and 47 denotes a driving circuit which governs the "ON-OFF" control of the driving motor 46.
Reference numerals 48-51 designate clutches for transmitting driving force of the driving motor 46 to the rollers 3 and 6 and the roller pairs 4 and 5, and reference numerals 52-55 denote a drlving circuit which "ON-OFF" con trills each of the clutctrc?s 48-51. Each of the driving circuits 52-55 ' C)N-OFF" controls edch of the clutches 48-51 according to the control signals supplied from the microproces so MPU through the peripheral interface adapter PIA3.
As described above, the recording member is supplied from the cassette 1 to implement recording on it by the recording heads 12Y12B, and the recorded matter is then discharged into the discharge tray 1 5 through the transporting roller 6 and the liquid absorbing roller 1 6.
In the above-described embodiment, the liquid absorbing roller 1 6 may be replaced by a belt-shaped member having a similar function.
The recording member 2 is not limited to the sheet-shaped one as shown in Figure 1.
and there may also be used roll-shaped one.
As described above. according to the present invention. it is possible to prepare an original suitable for supplying to the overhead projector having a firmly fixed image of high quality on itself by removing unfixed ink from the recording member on which recording has been carried out by the use of the recording apparatus which comprises image forming means for forming an image on the recording member by using an ink and liquid absorbing means for removing unfixed ink from the recording member on which the image has been formed.
It should be noted that the present invention is also applicable where recording liquids other than inks are used for image formation on the recording member; and where removal of the unfixed recording liquid is achieved by adhesion to a removing member rather than by permeation. The invention may also be broadly applicable where image formation involves the use of dry rather than liquid colouring material.
