Description

  The present invention relates to a recording apparatus including a colorimetric unit.

  At the production site of printed matter, a proof is printed before entering the main print, and the image data is faithfully displayed with reference to the image displayed on the proofed print sample and the authentication color patch displayed with the image. Conventionally, color calibration for confirming whether a color is reproduced has been performed.

  On the other hand, the color of the image on the CRT monitor and the color of the image displayed on the print sample output from the output device such as a printer or an image setter are electronically based on a color management file called a profile. Digital matching for matching with a printer is widely spread and is performed at a print data production site or a printed material production site (Patent Document 1).

  Recently, in order to shorten the time required for proof printing, a form of color proofing called simple proofing that outputs proof paper directly from printing data for plate making is widely used. Large ink jet printers are used to output paper. When using a large inkjet printer to output proof paper, measure the color information of the authentication color patch and profile creation color patch using a measuring instrument called a colorimeter. Then, a correction value is obtained by comparing with the color of the print data on the CRT monitor based on the measurement result, and the color correction information is supplied to a printer driver which is a recording control device of the ink jet printer.

An ink jet printer in which such a colorimeter is attached to a carriage on which a recording head is mounted is disclosed in Patent Document 2 below. The colorimeter requires a backing (underlay) in a paired relationship in order to perform high-precision colorimetry.
JP-A-11-004353 JP 11-326056 A

  Conventionally, however, the backing for this colorimeter has been used because of the influence of ink stains and shape restrictions, and the black backing is less noticeable and the colorimetric results are less affected by the backing shape. Also, this backing was a structure that could not be replaced.

  Note that there is an ISO standard for backing, and this ISO standard also defines white backing in addition to black backing. Therefore, the conventional structure has a problem that a backing having a color based on the ISO standard cannot be used.

  The present invention has been made under such background art, and provides a recording apparatus that can perform high-precision color measurement and can use a backing having a color based on the ISO standard. It is an object to do.

  In order to solve the above problem, the recording apparatus according to the first aspect of the present invention is a recording apparatus including a color measurement unit, wherein a backing that is a component of the color measurement unit is made of a resin, and It is characterized in that it is detachably attached to the attachment position by the magnetic force of the magnet.

According to this aspect, since the backing is made of resin, the color of the backing can be stably produced with the required color, and can easily correspond to the color based on the ISO standard. Highly accurate colorimetry.
In addition, since it can be attached to and detached from the attachment position by the magnetic force of the magnet, the backing can be easily removed from the recording apparatus, and can be easily replaced with another color backing defined by the ISO standard.

  The recording apparatus according to a second aspect of the present invention is the recording apparatus according to the first aspect, wherein the backing is magnetically attached to the base plane by a plurality of magnets at the mounting position, and the surface of the backing is the base plane. It is characterized by being corrected to a planar shape following the above.

  When the resin material is made into a plate-like material, the thickness and the surface smoothness can be made with high accuracy, but there is a drawback that the entire plate-like surface is easily bent. This drawback becomes more pronounced as the size increases. For this reason, it is difficult for the resin material to satisfy the flatness without warping required for the backing.

  However, according to this aspect, the resin backing is magnetically attached to the base plane satisfying the flatness without warping required for the backing by the plurality of magnets, and the surface of the resin backing follows the base plane. Therefore, the drawbacks of the resin material can be eliminated, and the advantages can be exhibited effectively. The base plane can be easily made of a metal material. Metal materials cannot meet the color requirements, but flatness without warping can be easily achieved.

  The recording apparatus according to a third aspect of the present invention is the recording apparatus according to the second aspect, wherein a magnet or a magnetic body is disposed on the back surface of the backing, and the magnet or the magnetic body It is characterized by being attached by magnetic force with a gap between them.

  According to this aspect, the magnet or the magnetic body disposed on the back surface of the backing is attached by a magnetic force with a gap between the base plane of the magnetized counterpart. Therefore, even if there is a magnet or a magnetic body that is a member for attaching the backing to the base plane, the existence of the magnet or the like does not affect the distance from the base plane to the backing surface because the gap is provided. That is, the distance from the base plane to the backing surface is a structure determined only by the thickness of the resin backing. Therefore, when the user replaces the backing, simply align the new backing with its mounting position, and the magnetic force of the magnet and the gap ensure that the new backing is corrected to a flat shape that follows the base plane. Thus, the magnetic force is fixed and necessary flatness can be ensured.

  The recording apparatus according to a fourth aspect of the present invention is the recording apparatus according to the third aspect, wherein the magnet or magnetic body is detachably provided on the backing. Thereby, the attachment and replacement | exchange to the said backing of a magnet or a magnetic body can be performed easily.

It is characterized by being.

When the thickness of the backing is reduced, it is transparent even if the surface is covered. Therefore, even if a magnet is disposed on the back side of the backing, the colorimetric result is greatly affected if it is seen through the surface of the backing.
According to this aspect, since the magnet or the magnetic body is provided at a position away from the color measurement part by the color measurement unit, even if the backing is thin and the magnet can be seen through, the color measurement result It does not affect. In particular, when the invention of this aspect is applied to white backing, the effect is remarkable.

  The recording apparatus according to a sixth aspect of the present invention is the recording apparatus according to any one of the first to fifth aspects, wherein a colorimetric region is provided in a part of the backing when attached to the recording apparatus. It is characterized by that.

If the structure allows the replacement of the backing, there is a risk that problems such as replacement mistakes and forgetting the installation itself may occur.
According to this aspect, since the recording apparatus includes the colorimeter, it is possible to measure the color of the backing itself with the colorimeter by providing a colorimetric region in a part of the backing. . By directly measuring the color of the backing in this way, the recording apparatus itself can determine whether the backing type is wrong or the backing itself is forgotten to be attached (self-identification), and the necessary measures can be taken. Further, it is possible to easily determine whether the backing color matches the ISO standard (self-determination).

The backings are connected by the magnetic force of the magnet.

  When the length of the backing is increased, the backing itself is likely to be twisted or bent. Therefore, a large number of large magnets are required to attach the backing so as to follow the base plane (made of a metal plate such as iron). As a result, for example, when a large magnet is provided on the backing, the thickness of the backing is increased, leading to a problem that the backing is increased in size.

  According to this aspect, since a plurality of short backings configured to have a short length in the longitudinal direction are connected in the longitudinal direction to form a single long backing, one long backing is formed on the base plane ( Compared to the case of mounting so as to follow (made of a metal plate such as iron), twisting and bending of the backing itself are reduced. Accordingly, the backing can be attached to the base plane with the magnetic force of a small magnet. Accordingly, since a small magnet can be used, the thickness of the backing itself can be reduced. In addition, since the mold can be small, the cost of the product can be reduced.

  The recording apparatus according to an eighth aspect of the present invention is the recording apparatus according to the seventh aspect, wherein the magnet also functions as the magnet in the first aspect. With this dual-use structure, the number of parts and cost can be further reduced.

That is, the backing can be designed to be thin. Furthermore, since the magnets and the like are locked so as not to come off, the magnets and the like will not fall out even when an inadvertent force is applied.

  The recording apparatus according to an eleventh aspect of the present invention is the recording apparatus according to the ninth or tenth aspect, wherein an engagement portion is provided at one connection portion of the adjacent backing and an engagement portion is provided at the other connection portion. When the other backing portion is engaged with one of the engaged portions when the backings are connected to each other, the abutting side portion is configured to be able to shift to the contact state by the magnetic force. It is characterized by being.

It is characterized in that it is mounted so as to be capable of relative displacement in the direction intersecting the conveying direction of the recording material with respect to the position.

  When the base plane is made of a metal plate made of a magnetic material such as iron, the expansion rate and contraction rate of the metal and the resin that is the backing material are different. If there is no degree of freedom with respect to the plane, there is a problem that the backing is distorted or a gap is generated between the backings.

  However, according to this aspect, one backing is fixed at one position with respect to the mounting position (base plane), and the other backing is mounted so as to be relatively displaceable in the longitudinal direction with respect to the mounting position. The above-mentioned problems that occur when the plane expands or contracts do not occur.

  The recording apparatus according to a thirteenth aspect of the present invention is the recording apparatus according to any one of the first to sixth aspects, wherein a plurality of the backings are connected to each other in a direction intersecting the recording material conveyance direction. The connecting portion is formed by a press-fitting structure, and adjacent backings are part of the connecting portion by a pressing force based on press-fitting by press-fitting and connecting at the connecting portion. It contacts at a hitting edge part, It is characterized by the above-mentioned.

[Description of backing]
Next, referring to FIGS. 5 to 7 and FIGS. 15 to 18, the structure of the backing according to the present invention which is paired with the colorimeter in color measurement will be described. 15 is a perspective view of the main part of the backing according to the embodiment of the present invention, FIG. 16 is a perspective view of the main part of the back surface of the backing, FIG. 17 is a longitudinal sectional view of the state where the backing is attached, and FIG. FIG.

  As shown in FIGS. 5 to 7, the backing 80 according to the present embodiment is located at a position facing the pressing member of the color measurement device unit, and has a magnet on the surface of the metallic conveyance guide plate 11 of the printer main body. It is detachably attached by 81 magnetic force. This position is a downstream position with respect to the recording head 13, and is a position where the user can easily access from the front of the printer.

  The backing 80 has a rectangular plate shape, and is made of a resin material by injection molding. Therefore, although the thickness and the surface smoothness are made with high accuracy, the whole tends to bend slightly due to warping. The upstream surface in the transport direction of the recording material P is formed as an inclined surface that descends toward the upstream, and ensures smooth transport of the recording material. Examples of the resin material include, but are not limited to, an acrylic resin material. A general-purpose magnet 81 can be used.

  The backing 80 is magnetized by a plurality of magnets 81 on a base plane 11 (denoted using the same reference numerals) formed by the surface of the transport guide plate 11 at the mounting position. The multi-point magnetic attachment by the plurality of magnets 81 corrects the surface 82 of the backing 80 to a planar shape that follows the base plane 11, and the surface 82 is free from bending due to the warp and is required for the backing 80. Flatness is ensured. Incidentally, a pin 98 is integrally projected on the back surface of the backing 80 (FIG. 17), and the pin 98 is positioned by entering a hole formed at the mounting position of the base plane 11.

  A magnet 81 is disposed on the back surface 83 of the backing 80, and the magnet is attached by a magnetic force with a gap 84 between the magnet and the base plane 11 to which it is attached. That is, the magnet 81 is slid in the lateral direction (see FIG. 16) while the flexible locking piece 86 is pushed down into the mounting groove 85 of the magnet 81, and the flexible locking piece 86 is returned. As a result, the magnet 81 is held in the groove 85. That is, the magnet 81 is detachably provided on the backing 80.

  Dropping from the opening of the groove 85 is prevented by a locking portion 87. As shown in FIG. 18, the locking portion 87 has the thickness T of the backing 80 itself. The thickness T also defines the distance T from the base plane 11 to the surface 82 of the backing 80. ing. This thickness L is 2 mm in this embodiment, and the thickness K of the upper part of the magnet 81 is 1 mm.

  In addition, although demonstrated based on FIG. 18, the structure which made the magnet 81 only the magnetic body 90 and gave the magnetism to the base plane 11 side may be sufficient.

  In the present embodiment, the magnet 81 (or the magnetic body 90) is provided at a position away from the colorimetric part 91 by the colorimeter 31 (see FIGS. 7 and 17). When the thickness of the backing 80 is reduced, it is transparent even if the surface is covered. Therefore, even if the magnet 81 is disposed on the back side of the backing 80, the color measurement result is greatly affected if the magnet 81 is seen through the surface of the backing 80. According to this configuration, since the magnet 81 is provided at a position away from the colorimetric portion 91 by the colorimeter 31, even if the backing 80 is thin and the magnet can be seen through (see FIG. 18). Thickness K part), does not affect the color measurement result. In particular, when this configuration is applied to white backing, the effect is remarkable.

  Further, in this embodiment, a colorimetric region 92 is provided in a part of the backing 80 in a state attached to the recording apparatus (FIGS. 5 and 6). If the backing 80 can be replaced, there is a risk that problems such as replacement mistakes and forgetting the installation itself may occur.

  According to this configuration, since the recording apparatus includes the colorimeter 31, the colorimeter 31 measures the color of the backing 80 itself by providing a colorimetric region 92 in a part of the backing 80. It becomes possible. By directly measuring the color of the backing 80 in this manner, the recording apparatus itself can identify (self-identify) a mistake in the type of the backing 80 or forgetting to attach the backing itself, and the necessary measures can be taken. Further, it is possible to easily determine whether the backing color matches the ISO standard (self-determination).

[Explanation about the connection structure 1 between backings]
Next, an example in which a plurality of short backings 80a and 80b having a short length in the longitudinal direction are connected in the longitudinal direction to form one long backing 80 will be described with reference to FIGS. To do. FIG. 19 is a main part perspective view showing the surface of the connection part between adjacent backings, and FIG. 20 is a main part perspective view showing the connection part between adjacent backings from the back surface.

  19 and 20, one short backing 80a includes a connecting portion 93a having a groove as an engaged portion, and a part of the connecting portion 93a has an abutting side portion 94a. . Further, on the connecting portion 93a, magnets 81 (or magnetic bodies 90) are formed on both sides of the abutting side portion 94a with respect to the short side direction of the backing 80a from the back side of the backing 80a. Further, the stopper 95 is arranged so as not to fall off the backing 80a.

  19 and 20, the other short backing 80b is provided with a connecting portion 93b having an engagement portion, and a part of the connecting portion 93b has an abutting side portion 94b. Further, the connecting portion 93b has a magnet 81 (or a magnetic body 90) on both sides of the abutting side portion 94b with respect to the short side direction of the backing 80b. 87 and the stopper 95 are arranged so as not to fall off the backing 80b.

  The magnets 81 or the magnetic bodies 90 arranged at the connecting portions of the backings 80a and 80b are exposed at portions facing each other, and have a clearance 96 when the backings 80a and 80b are connected. By exposing the portions facing each other, the backings 80a and 80b can be attracted with a small magnetic force, and by having the clearance 96, the backing side portions 94a are not in contact with the backings 80a and 80b. , 94b ensures that the backings come into contact with each other.

  Then, by making sure that the backings are brought into contact with each other at the abutting sides 94a and 94b, the colorimetry at the abutting sides 94a and 94b that pass when the colorimeter measures the color can be performed accurately. It has become. Although it is desirable that the backings 80a and 80b are in contact with each other at the abutting sides 94a and 94b, it has been confirmed that there may be some gap. If this gap is 0.2 mm or less, colorimetry is not affected. Therefore, even if there is such a gap, it can be said that the “contact” state of the abutting sides 94a and 94b in the present invention is achieved.

  Further, if there is a magnetic force large enough to attract the backings 80a and 80b, the magnet 81 or the magnetic body 90 may not have a structure in which portions facing each other are exposed.

  Further, the magnet 81 in the embodiment shown in FIG. 19 has the function of the magnet 81 shown in FIG. 18, that is, the function of attaching the backing by a magnetic force with a gap between the base plane of the magnetized counterpart. It is also configured. With this dual-use structure, the number of parts and cost can be further reduced.

In this embodiment, one backing (for example, 80a) is fixed at one position with respect to the mounting position, and the other backing (for example, 80b) intersects the recording material conveyance direction with respect to the mounting position. It is attached to be capable of relative displacement. That is, one backing 80a is positioned by the pin 98 entering the hole formed at the mounting position of the base plane 11, while the other backing 80b is relatively relative to the mounting position of the base plane 11 in the longitudinal direction. Mounted displaceably.
That is, the shape of the hole formed at the mounting position of the base plane 11 is a long hole in the longitudinal direction, and the pin 98 is inserted into this hole, so that the other backing 80b is within the range of the long hole. It is attached so as to be capable of relative displacement in the longitudinal direction with respect to the attachment position of the base plane 11.

  Accordingly, since one backing 80a is fixed at one position with respect to the mounting position (base plane) and the other backing 80b is mounted so as to be relatively displaceable in the longitudinal direction with respect to the mounting position, the base plane 11 expands. When shrinking, the backing is not distorted, and there is no gap between the backings.

  Here, a method in which the user connects backings will be described.

  The user engages the connecting portion 93b having the dovetail as the engaging portion of the backing 80b into the connecting portion 93a having the dovetail groove as the engaged portion of the backing 80a. At this time, there is a gap between the backings 80a and 80b, but the backings 80a and 80b are attracted by the magnetic force of the magnet 81 and come into contact with each other at the abutting sides 94a and 94b, thereby completing the connection between the backings 80a and 80b. Therefore, the user can easily and accurately connect the backings 80a and 80b only by inserting the presence of the other backing 80b into the groove of the one backing 80a.

  In order for the backings 80a and 80b to be attracted to each other by the magnetic force of the magnet, the combination of the opposing magnet 81 or magnetic body 90 is that one is the magnet 80 and the other is the magnet 80 or one is the magnet 80 and the other is the magnetic body 91 Needless to say.

[Explanation about the connection structure 2 between backings]
The connection between the backings 80a and 80b can be achieved even by a pressing force based on press-fitting by making the connecting portion a press-fitting structure, even if the connection is not a magnetic connection. In the case of the connection by the press-fitting structure, the backings can be easily brought into contact with each other at the abutting side by simply press-fitting (for example, fitting) the connection part of the other backing into the connection part of the one backing. Therefore, it is not necessary to provide a magnet or the like at the connection portion.

Next, the operation of the backing 80 will be described.
According to the present embodiment, since the backing 80 is made of resin, the color of the backing 80 can be stably produced with the required color, and can easily correspond to the color based on the ISO standard. Therefore, highly accurate colorimetry can be performed. In addition, since it can be attached to and detached from the attachment position by the magnetic force of the magnet 81, the backing 80 can be easily detached from the recording apparatus and can be easily replaced with another color backing defined by the ISO standard. .

  Further, a resin backing 80 is magnetically attached to the base plane 11 satisfying the flatness without warping required for the backing 80 by a plurality of magnets 81, and the surface 82 of the resin backing 80 follows the base plane 11. Since the shape is corrected, the disadvantages of the resin material can be eliminated and the advantages can be effectively exhibited.

  In addition, the magnet 81 or the magnetic body 90 disposed on the back surface of the backing 80 is attached by a magnetic force with a gap 84 between the magnet 81 and the base plane 11 of the magnetized counterpart. Therefore, even if the magnet 81 or the magnetic body 90 which is a member for attaching the backing 80 to the base plane 11 exists, the presence of the magnet 81 or the like provides the gap 84 at a distance L from the base plane 11 to the backing surface 82. It has no effect at all. That is, the distance L from the base plane 11 to the backing surface 82 is a structure determined only by the thickness T of the resin backing. Therefore, when the user replaces the backing 80, the new backing 80 follows the base plane 11 simply by aligning the new backing 80 with its mounting position, and the magnetic force of the magnet 81 and the gap 84. The flat shape is surely corrected and the magnetic force is fixed, and the required flatness can be ensured.

  Next, (1) the operation mode at the time of color measurement and (2) the operation mode at the time of non-color measurement of the colorimetry device unit 1 of the present invention configured as described above will be described.

(1) Mode of operation during color measurement At the time of color measurement, the colorimeter 31 is set in the colorimeter holder 32 so as to be inserted from the front. In this case, the colorimeter 31 inserted into the colorimeter holder 32 is measured by the locking action of the locking pin 40 and the locking hole 43 and the downward biasing force of the pressing spring 50. 32. Then, the connector wiring 38 is connected to the socket 39 of the colorimeter 31. Next, the roll paper R or the cut sheet P on which the color patch B is recorded is transported from the upstream position in the transport direction A toward the downstream position, and is stopped when the color measurement position is reached.

  In this state, when the color measurement device unit 1 is started by operating a predetermined start switch, the pressing member drive motor 70 rotates in the forward rotation direction to bring the pressing member 34 into a pressing posture indicated by a solid line in FIG. . In this state, the pressing plate 48 is in contact with the surface of the roll paper R or the cut sheet P on which the color patch B is not recorded by the action of the pressing plate support spring 65 and the pressing plate pressure spring 66 described above. Touching and pressing. A color patch B for color measurement is located below the long hole 49.

  Next, the carriage drive motor 54 starts rotating, and the timing belt 59 is driven to move the colorimeter carriage 51 from the home position area to the color measurement area, so that the traveling wheel 47 is placed on the upper surface of the pressing plate 48 in the pressing posture. Set to ground. The timing belt 59 continues to drive as it is, and the colorimeter 31 held by the colorimeter carriage 51 together with the colorimeter carriage 51 starts moving in order from the color patch B located closer to the home position toward the return position. To do. In this embodiment, the color information measured by the colorimeter 31 is sent to a processing device (not shown), and a correction value is calculated by comparing with the color information of the image displayed on the monitor. 100 is supplied to the printer driver 100 and is reflected in the subsequent execution of recording.

(2) Operation mode during non-colorimetry When the colorimeter 31 measures the color information of all the color patches B, the carriage drive motor 54 rotates in the reverse direction, and the colorimetry located at the return position. The container 31 starts moving toward the home position. When the colorimeter 31 reaches the home position, the upper surface of the white tile 36 is covered with the colorimeter 31 to prevent dust and the like from adhering to the upper surface of the white tile 36. Next, the pressing member drive motor 70 rotates in the reverse direction, and the rotation is transmitted to the pressing member 34 via the gear wheel train 71 and the sector gear 67 to rotate the pressing member 34 upward. In FIG. 5, the retracted posture jumps upward as indicated by the phantom line. In this state, since the roll paper R and the cut sheet P can be conveyed in the conveyance direction A, the color patch B in the upper row positioned upstream in the conveyance direction A through the blank portion D to the colorimetric position. The roll paper R and the cut paper P accompanying the original recording execution by the inkjet printer 100 can be executed.
