Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an image recording apparatus for recording an image on the surface of a rigid recording medium such as a compact disk.

[0002]

2. Description of the Related Art Generally, a recording medium such as a compact disk has rigidity and hardly any flexibility. Therefore, as a means for recording an image such as a label on the surface of such a rigid recording medium, a printing method such as screen printing or offset printing has been conventionally used.

[0003] However, in such a conventional printing method, it is necessary to prepare a screen plate or an offset plate for each color used in the original image to be printed. For this reason, as the number of original images increases, the number of screen plates and offset plates increases, and it is necessary to attach these multiple plates to a printing apparatus while performing fine alignment. Further, while the number of colors is limited due to the configuration of the printing apparatus, it is necessary to newly prepare ink of a color corresponding to the required color.

[0004] Therefore, a screen version or an offset version is required as an expense, and it takes days to produce.
In particular, the preparation process before starting printing is troublesome. For this reason, when printing a lot with a small number of prints, there is also a disadvantage that the printing cost per recording medium is relatively high.

[0005] Further, after the printing is completed, it takes time and effort to wash the ink and to treat the waste liquid, and special treatment facilities are required. In addition, since the size of the device increases in proportion to the number of plates to be used, an installation space for a large device is required, and when storing a printed plate for reprinting or the like, It also needed space for plate storage.

[0006]

SUMMARY OF THE INVENTION It is an object of the present invention to provide an image recording apparatus capable of printing a high-quality image on a disk-shaped recording medium, printing with high productivity, and the like. And

[0007]

In order to achieve the above object, an image recording apparatus according to the present invention comprises an image recording apparatus for recording an image using a recording means for performing a recording operation on a recording surface of a recording medium.

Here, the recording means may include a recording head for performing a recording operation on the recording medium on the transport means while reciprocating in a direction orthogonal to the transport direction of the transport means.

The image reading means may be capable of reciprocating on the recording medium in synchronization with the reciprocating movement of the recording means.

[0010] The recording means may include a long recording head extending in a direction perpendicular to the conveying direction of the conveying means.

The image reading means may be arranged downstream of the recording means in the conveying direction of the conveying means.

The transport means may be capable of mounting a plurality of recording media in a direction perpendicular to the transport direction.

[0015] The recording means may be an ink jet recording means, and the ink jet recording means may have a thermal energy generator for generating energy used for discharging ink. The body is
An electrothermal converter that generates thermal energy that causes film boiling of the ink may be used.

In the present invention, since an image is directly recorded on a disk-shaped recording medium by digital image information, a printing plate is not required, so that the number of printing steps and days can be greatly reduced, and the apparatus can be downsized. Further, image information for printing can be stored in a recording medium such as a tape, a flexible disk, an optical disk, and the like, and further, the preservability of the image information is excellent. In addition, processing such as color change, layout change, enlargement, and reduction of the original image can be easily performed. Particularly, it is possible to continuously record an image on a disk-shaped recording medium on a conveyor belt, and mass productivity is high.

[0017]

Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1) FIG. 1 is a schematic plan view showing an embodiment of the image recording apparatus of the present invention.

The image recording apparatus according to the present embodiment is connected to a CPU serving as control means, which will be described later.
An image recording apparatus that transfers image recording data created in a PU to perform image recording may be mentioned. In the image recording apparatus of the present invention, for example, a recorded image is read like a copying machine, and then the image is recorded. Things shall be included.

In FIG. 1, reference numeral 1 denotes an endless transport belt, which is stretched and held by a drive roller 2 and a driven roller 3 disposed inside the transport belt. The belt surface of the transport belt 1 constitutes support means for supporting a disk-shaped recording medium described later, and the entire transport belt 1 constitutes transport means for moving the recording medium linearly.

The driving roller 2 is roughly composed of a metal shaft portion and a rubber coating portion having a high friction coefficient provided on the surface thereof, and the driven roller 3 is entirely formed of metal. . The drive roller 2 is rotationally driven in the direction of arrow A by a drive motor 4 provided on the shaft thereof, and frictionally drives the transport belt 1. As the drive motor 4, for example, a type such as a stepping motor that can stably drive and follow the conveyor belt 1 is used. The driven roller 3 is held while being displaced by stretching means (not shown) in the direction in which the transport belt 1 is stretched, and is driven to rotate in synchronization with the movement of the transport belt 1. In the present embodiment, the transport belt 1
Is formed of a rubber material having relatively high hardness so as to be integrally driven by the frictional force of the drive roller 2,
The expansion and contraction of the transport belt 1 due to the driving force is suppressed.
Therefore, as long as the expansion and contraction of the transport belt 1 due to the driving force can be suppressed, there is no problem even if the transport belt 1 is formed of another material such as a metal or a resin film.

On the surface of the conveyor belt 1, a so-called full-line type ink jet recording head 5 as recording means is provided at a constant interval. The recording head 5 is configured to form a predetermined image by being driven to be ejected from the CPU serving as control means to the surface of the recording medium based on an image signal. The ink ejection surface of the recording head 5 and the surface of the recording medium placed on the surface of the conveyor belt 1 are opposed to each other, and the distance between them is determined by the ideal flying distance of the ink ejected from the plurality of nozzles of the recording head 5. The distance, the discharge direction, and the like are determined in comprehensive consideration. Although not shown, a plurality of nozzles constituting a part of the ink ejection surface of the long recording head 5 are arranged along a direction (arrow B direction) orthogonal to the transport direction of the transport belt 1. The length of the plurality of nozzle rows is set larger than that of the recording medium so as to cover the entire recording medium placed on the transport belt 1.

Further, at a position downstream of the position of the recording head 5 in the transport direction, a CCD (charge coupled) as a long image reading means along the direction of arrow B is provided.
device) sensor 8 is provided. This CCD sensor 8 is, like the ink jet recording head 5,
It is fixed at a position separated by a certain distance from the surface of the conveyor belt 1. In this case, the separation distance is set to a distance sufficient to read an image recorded on the surface of the recording medium placed on the transport belt 1. Such a CCD sensor 8
Can read a recorded image on a compact disk (hereinafter, referred to as a CD) 11 as a recording medium on which an image is recorded by the recording head 5 arranged on the upstream side in the transport direction of the transport belt 1.

In the present embodiment, an automatic CD feeding unit 31 for feeding the CD 11 to the predetermined position of the transport belt 1 is provided on the transport belt 1 upstream of the transport belt 1 in the transport direction. The CD 11 supplied to the transport belt 1 by the automatic CD feeding unit 31 is prepared with data such as a press, and then, in order to easily hold the ink ejected from the recording head 5 to the label unit. The receiving agent is coated.

The automatic CD feeding section 31 is provided with
Conveyor 33 driven in a direction (arrow C direction) orthogonal to the transfer direction (arrow A direction)
3 schematically includes an air chuck means 34 for gripping the CD 11 mounted on the conveyor 3 at a predetermined position on the conveyor 33, and an arm 35 for transporting the air chuck means 34 to a predetermined mounting position on the conveyor belt 1. I have. The air chuck means 34 includes a CD 11 serving as a non-recorded image area.
In this case, the CD 11 itself is to be gripped by sucking the vicinity of the inner diameter of the CD 11, and the label portion of the CD 11 is not damaged by the suction or the like.

The automatic discharge unit 32 is provided with the conveyor 3
3, the conveyor 36 driven to be transported in a direction (arrow C direction) orthogonal to the transport direction (arrow A direction) of the transport belt 1 and the CD 11 transported to the most downstream side of the transport belt 1 Air chuck means 37 for gripping;
An arm 38 for transporting the air chuck means 37 to a predetermined position on the conveyor 36 is schematically constituted.

The conveyor 36 of the automatic discharge section 32
In the vicinity of the CD, an abnormality is detected in the recorded image by the CCD sensor 8 and the arm 38 removes the CD from the normal path.
11 is provided with a stock portion 43 for holding the same.

Next, a recording operation and an image reading operation in the present embodiment will be described.

First, the CD 11 on which data is prepared by means such as a press and coated with the above-mentioned acceptor is continuously conveyed to the upstream side of the conveyor belt 1 by the conveyor 33, Each of them is gripped one by one, and is transferred from the conveyor 33 to a predetermined position on the conveyor belt 1 with high precision by swinging by the arm 35.

Next, by the transport driving of the transport belt 1, C
D11 passes below the full line type recording head 5. At this time, recording on the label portion of the CD 11 by the recording head 5 is started at a certain timing from the rotation start signal of the driving roller 2.

Next, the CD 11 on which a recording image has been formed by passing under the recording head 5 is moved at a constant speed to the CCD 11.
It passes under the sensor 8. At this time, the CCD sensor 8 detects whether there is an abnormality in the recorded image of the label portion of the CD 11. This detection is performed in comparison with the image recording data transferred to the inkjet recording head 5. For example, in the label portion of the CD transported downstream in the transport direction of the transport belt 1 in FIG. 1, “ABC” is recorded in the upper row, and “DEF” is recorded in the lower row, and these are the same as the image recording data. And there is no abnormality. However, in the label portion of the CD already placed on the stock portion 43, “ABC” is recorded in the upper row, and only “DE” is recorded in the lower row. When compared (collated) with the image recording data, the "F" to be recorded in the lower part is missing, and by reading with the CCD sensor 8, it is possible to detect a clear abnormality in the recorded image. In this case, the abnormality detection CD is transferred to the stock unit 43 and a warning is issued.

CD in which such image abnormality is not detected
Is placed at a predetermined position on the conveyor 36 by the automatic discharge unit 32 and transferred to the next step. In the next step, the label portion is coated with a transparent resin for the purpose of drying the ink discharged to the label portion and further protecting the image.

In this embodiment, since the recording head 5 of the full line type is used as described above,
Can be recorded on the label portion of the CD 11 with the print nozzle width of the recording head 5 while driving the CD 11 at the transport speed determined by the frequency at which the recording head 5 is driven.

In this embodiment, the operation and the function of detecting the barcode provided on the peripheral edge of the through hole of the CD 11 and comparing and checking it with the image recording data are the same as those described above. Then, the image is not recorded on the CD 11, and the recording belt 5 is directly passed by the transport belt 1 without being image-recorded. Thereafter, the CD 11 is discharged to the stock unit 43 by the automatic discharge unit 32. Thereafter, the same recording operation is repeatedly performed, and image recording is continuously performed on the CD 11.

The timing of such continuous recording on the CD is such that the image recording on the next CD is started immediately after the CCD sensor 8 finishes comparing the recorded images, and an abnormality is detected. In some cases, the image recording is set to be interrupted before the next recording starts.

As shown in FIG. 2A, the CD 11 has a circular shape of, for example, 120 mm and is about 15 mm mounted on a compact disc player (not shown).
At the center thereof. Around the through hole 12H of the CD 11, there are a lead-in area 12RI in which a tune of recorded audio information or its address is recorded, a program information recording area 12RA in which audio information is recorded, and a lead-out area 12RO. Is formed.

As shown in FIGS. 2B and 2C, the lead-in area 12RI and the program information recording area 12RA are formed by a writing light beam modulated based on a reproduced audio signal to be recorded. Pit 1 to be formed
2pi includes a substrate portion 2B spirally arranged on one surface portion and a protective film 2F covering one surface portion of the substrate portion 2B.

For example, each pit 12pi in the substrate portion 2B made of a transparent polycarbonate resin has, for example, a width of 0.5 μm, a length of 0.9 to 3.3 μm, and a depth of 0.1 μm.
1 μm. On the bottom of each pit 12pi,
A reflection film 12rf made of an aluminum alloy is provided.

In addition, the periphery of the through hole 12H is shown in FIG.
As shown in (A), a bar code 2BC representing the content of image data to be printed on the label unit 2PA is formed.

Further, in the portion of the protective film 2F facing the lead-in area 12RI and the program information recording area 12RA of the substrate section 2B, the contents of the music recorded in the program information recording area 12RA, the production company, etc.
Also, a label section 2PA that is printed with a graphic is provided.

Next, the CD 1 mounted on the conveyor belt 1
FIGS. 3A and 3B show the relationship between 1 and the CCD sensor 8.
This will be described with reference to FIG.

The length of the CCD sensor 8 along the width direction of the conveyor belt 1 is, for example, as shown in FIG.
It is longer than the diameter of the CD 11, for example, set to about 140 mm. In this case, the CD 11 is
Even if the CD 11 is not arranged at a predetermined position and is slightly biased in one direction, the outer shape of the CD 11 and the label portion 12PA
Is photographed by the CCD sensor 8 and can be detected. Also in this case, the CD transported by the transport belt 1
Eleven positions and outer shapes are photographed and can be detected.

The CC along the width direction of the conveyor belt 1
The length of the D sensor 8 is, as shown in FIG.
It may be shorter than the diameter of D11, for example, set to about 70 mm. In this case, a through hole 12H having a diameter of 15 mm
The bar code 12BC and a part of the label portion 12PA provided on the periphery thereof can be photographed by the CCD sensor 8. Thus, the position of the CD 11 conveyed by the conveyor belt 1 and the barcode 12BC can be photographed and detected.

(Embodiment 2) Next, another embodiment of the image recording apparatus of the present invention will be described with reference to FIG. Note that among the constituent elements of the present embodiment, those that are common to the constituent elements of the previous embodiment are denoted by the same reference numerals, and description thereof will be omitted.

In the present embodiment, unlike the previous embodiment,
In order to increase the productivity of image recording, the conveyor belt 1
Is characterized in that a plurality of CDs can be placed at the same time in the width direction (the direction of arrow B) and can be transported at the same time. In the present embodiment, four CDs can be placed at the same time, and CDs 51, 52,
53 and 54.

The recording head 5 in this embodiment is mounted on the carriage C together with the CCD sensor 8, and is configured to be able to reciprocate in the direction of arrow B. That is, the carriage C is moved in the width direction of the transport belt 1 (arrow B).
) Are slidably supported by a pair of support shafts 45 and 46 extending along the direction (i.e., direction), and the print nozzles of the recording head 5 are arranged in the direction of arrow A.

The CD 51 for which data has been created by the press or the like is continuously conveyed by the conveyor 33 to the vicinity of the upstream side of the conveying belt 1 in the conveying direction.
Swings, holds the CD 51 by suction by the air chuck means 34, and transfers the CD 51 from the conveyor 33 to the conveyor belt 1. Similarly, the CDs 52, 53, and 54 are placed adjacent to each other at regular intervals and in a line, and are placed on the transport belt 1 in a stopped state. The transport belt 1 starts to be driven by a signal indicating that the loading of the CD 54 has been completed, and the CDs 51 to 54 pass through the drive area of the recording head 5 and drive the recording head 5 at a timing determined from the transfer start signal of the transport belt 1. Stop at a predetermined position in the area.

Recording is performed by moving the carriage C in the direction of the arrow B in the CD direction.
The recording is performed sequentially on the label portions of the CDs 52 to 54 while moving from the 51 side.

While the belt is stopped and the recording head 5 is scanning and recording, the next four CDs are placed on the transport belt 1 in the same manner as the CDs 51 to 54. The recording head 5 is a CD54
After the recording for the image is completed, the carriage returns to the scanning start position. During this time, the transport belt 1 starts to be transported, and the CD on which the next recording is to be performed is transported to the above-described recording position to enable continuous image recording.

The CCD sensor 8 mounted on the carriage C adjacent to the recording head 5 moves in the transport direction (arrow A).
Direction), and has a sensor surface having substantially the same length as the length of the print nozzle of the recording head 5. For this reason, the CCD sensor 8 is scanned integrally with the recording head 5 when the recording head 5 scans and records, and the CD 51 is immediately scanned.
54 can be read, and the recorded image can be compared and checked with the image recording data in the same manner as in the previous embodiment.

Next, irrespective of whether or not an abnormality is detected in the recorded image, the CDs 51 to 54 are transported again in the direction of arrow A, and are discharged by the discharge unit 32 at a position downstream of the transport belt 1 in the transport direction. Numerals 54 are sequentially sucked by the air chuck means 37 supported by the swing arm 38, and when there is no abnormality in the recorded image according to the information of the CCD sensor 8, the image is transferred onto the conveyor 36 and sent to the next step. If an abnormality is detected here, the next four CDs
Is stopped without performing the scan recording operation for. After this,
CDs on which no abnormality was detected as described above are on conveyor 3
6, but the CD for which an abnormality has been detected is not transferred onto the conveyor 36, and the air chuck means 37.
As a result, a warning is issued at the same time as being transferred to and mounted on the stock unit 43. Thereafter, after the maintenance of the abnormal image, the image recording is started by inputting a restart signal, and the same recording operation is repeated.

In this embodiment, in order to arrange a plurality of CDs at predetermined positions on the conveyor belt 1 or to discharge the arranged CDs to the outside of the conveyor belt 1, an automatic CD feeding unit is used. The configuration of the automatic discharge unit 31 and the automatic discharge unit 32 is different from the previous embodiment. That is, the transport belt 1 is driven in a direction (arrow B direction) perpendicular to the transport direction.
Since there is no means for moving the
The feeding unit 31 and the automatic discharging unit 32 may be configured to be relatively movable with respect to the conveyor belt 1, or the arm 35 of the automatic CD feeding unit 31 and the arm 38 of the automatic discharging unit 32 may be configured to be extendable. it can. Alternatively, a configuration in which a plurality of air chuck means are provided in one arm, and a configuration in which an individual automatic CD feeding section and an automatic discharging section are dedicated to each CD can be adopted.

Although the CCD sensor 8 is mounted on the same carriage C as the recording head 5 in the present embodiment, the CCD sensor 8 does not need to ride on the carriage C with the recording head 5. . For this reason, the CC is placed on another carriage that can reciprocate in synchronization with the carriage C.
A configuration in which the D sensor 8 is mounted can also be adopted.

In the present embodiment, an ink jet recording apparatus has been described as an example of the image recording means. However, the present invention is not limited to this, and may be applied to a recording apparatus which can directly record an image on a recording medium such as a thermal transfer recording apparatus. Can also be applied.

(Others) It should be noted that the present invention includes a means (for example, an electrothermal converter or a laser beam) for generating thermal energy as energy used for performing ink ejection, particularly in an ink jet recording system. An excellent effect is obtained in a recording head and a recording apparatus of a type in which the state of ink is changed by the thermal energy. This is because according to such a method, it is possible to achieve higher density and higher definition of recording.

The typical configuration and principle are described in, for example, US Pat. Nos. 4,723,129 and 4,740.
It is preferable to use the basic principle disclosed in the specification of Japanese Patent No. 796. This method is a so-called on-demand type,
Although it can be applied to any type of continuous type, in particular, in the case of the on-demand type, it can be applied to a sheet holding liquid (ink) or an electrothermal converter arranged corresponding to the liquid path. By applying at least one drive signal corresponding to the recorded information and providing a rapid temperature rise exceeding nucleate boiling, heat energy is generated in the electrothermal transducer, and film boiling occurs on the heat acting surface of the recording head. Liquid (ink) corresponding to this drive signal on a one-to-one basis.
This is effective because air bubbles inside can be formed. The liquid (ink) is ejected through the ejection opening by the growth and contraction of the bubble to form at least one droplet. When the drive signal is formed into a pulse shape, the growth and shrinkage of the bubble are performed immediately and appropriately, so that the ejection of a liquid (ink) having particularly excellent responsiveness can be achieved, which is more preferable. As the pulse-shaped drive signal, those described in US Pat. Nos. 4,463,359 and 4,345,262 are suitable. Further, if the conditions described in US Pat. No. 4,313,124 relating to the temperature rise rate of the heat acting surface are adopted, more excellent recording can be performed.

As the configuration of the recording head, in addition to the combination (straight liquid flow path or right-angle liquid flow path) of the combination of the discharge port, the liquid path, and the electrothermal converter as disclosed in the above-mentioned respective specifications, U.S. Pat. No. 4,558,333 and U.S. Pat. No. 44,558 which disclose a configuration in which a heat acting portion is arranged in a bending region.
A configuration using the specification of Japanese Patent No. 59600 is also included in the present invention. In addition, Japanese Unexamined Patent Application Publication No. 59-123670 discloses a configuration in which a common slit is used as a discharge portion of an electrothermal converter for a plurality of electrothermal converters, and an aperture for absorbing a pressure wave of thermal energy is provided. The effect of the present invention is effective even if the configuration is based on JP-A-59-138461, which discloses a configuration corresponding to a discharge unit. That is, according to the present invention, recording can be reliably and efficiently performed regardless of the form of the recording head.

Further, the present invention can be effectively applied to a full-line type recording head having a length corresponding to the maximum width of a recording medium on which a recording apparatus can record. Such a recording head may have a configuration that satisfies the length by a combination of a plurality of recording heads, or a configuration as one integrally formed recording head.

In addition, even in the case of the serial type as described above, a recording head fixed to the apparatus main body or an electric connection with the apparatus main body or ink from the apparatus main body is mounted on the apparatus main body. The present invention is also effective when a replaceable chip-type recording head that can be supplied or a cartridge-type recording head in which an ink tank is provided integrally with the recording head itself is used.

Further, it is preferable to add a recording head ejection recovery unit, a preliminary auxiliary unit, and the like as the configuration of the recording apparatus of the present invention since the effects of the present invention can be further stabilized. If these are specifically mentioned, the recording head is heated using capping means, cleaning means, pressurizing or suction means, an electrothermal transducer, another heating element or a combination thereof. Pre-heating means for performing the pre-heating and pre-discharging means for performing the discharging other than the recording can be used.

The type and number of recording heads to be mounted are not limited to those provided only for one color ink, for example, and for a plurality of inks having different recording colors and densities. A plurality may be provided. That is, for example, the printing mode of the printing apparatus is not limited to a printing mode of only a mainstream color such as black, but may be any of integrally forming a printing head or a combination of a plurality of printing heads. The present invention is also very effective for an apparatus provided with at least one of the recording modes of full color by color mixture.

In addition, in the embodiment of the present invention described above, the ink is described as a liquid. However, an ink which solidifies at room temperature or lower and which softens or liquefies at room temperature may be used. In general, the ink jet method generally controls the temperature of the ink itself within a range of 30 ° C. or more and 70 ° C. or less to control the temperature so that the viscosity of the ink is in a stable ejection range. Sometimes, the ink may be in a liquid state. In addition, in order to positively prevent temperature rise due to thermal energy by using it as energy for changing the state of the ink from a solid state to a liquid state, or to prevent evaporation of the ink, the ink is solidified in a standing state and heated. May be used. In any case, the application of heat energy causes the ink to be liquefied by the application of the heat energy according to the recording signal and the liquid ink to be ejected, or to start solidifying when it reaches the recording medium. The present invention is also applicable to a case where an ink having a property of liquefying for the first time is used. In such a case, the ink
JP-A-54-56847 or JP-A-60-7
As described in Japanese Patent Publication No. 1260, it is also possible to adopt a form in which the sheet is opposed to the electrothermal converter in a state where it is held as a liquid or solid substance in the concave portion or through hole of the porous sheet. In the present invention, the most effective one for each of the above-mentioned inks is to execute the above-mentioned film boiling method.

In addition, the image recording apparatus of the present invention may be used not only as an image output terminal of an information processing apparatus such as a computer, but also as a copying apparatus combined with a reader or the like, or as a facsimile apparatus having a transmission / reception function. It may take a form.

[0064]

As described above, according to the present invention,
After recording, the image recorded on the recording medium by the image reading means is compared with the recorded data to check for abnormalities, so that a stable recorded image can be obtained.
