DESCRIPTION OF EXEMPLARY EMBODIMENTS

Example 1 (Fig. 1 to Fig. 10B)

Hereinafter, a recording apparatus according to an example as a liquid discharging apparatus of the invention will be described in detail with reference to attached drawings.
First, an outline of a recording apparatus 1 according to Example 1 of the invention will be described.
Fig. 1 and Fig. 2 are schematic perspective views of the recording apparatus 1 of the example. In addition, Fig. 3 is a perspective side sectional view of the recording apparatus 1 of the example. Also, Fig. 2 illustrates a state in which a part of a configuration member, such as a case body 12 is removed so as to easily describe an inside of the recording apparatus 1.
The recording apparatus 1 of the example includes a transportation mechanism 3 which transports a recording medium in a transportation direction A by an adhesive belt 2 (endless belt) supporting the recording medium as a medium on a supporting surface attached with an adhesive. In addition, a feeding portion (not illustrated) is included therein which is capable of setting the recording medium of a roll type and feeding the recording medium to the transportation mechanism 3. In addition, a recording mechanism 4 is included therein which performs recording by reciprocating a carriage 6 including a recording head 7 (refer to Fig. 4) as a discharging portion to a transportation region of the recording medium by the transportation mechanism 3 in a reciprocating direction B intersecting with the transportation direction A of the recording medium. Further, a winding mechanism (not illustrated) is included therein, which is capable of winding the recording medium on which recording is performed in the recording mechanism 4.
The transportation mechanism 3 of the example includes the adhesive belt 2 which mounts and transports the recording medium fed from the feeding portion, a driving roller 8 which moves the adhesive belt 2, and a following roller 9. The recording medium is attached to and mounted on a supporting surface of the adhesive belt 2.
However, an endless belt as a transportation belt is not limited to the adhesive belt. For example, an electrostatically attracting endless belt may be used.
Moreover, the recording apparatus 1 of the example includes the transportation mechanism 3 having such a configuration; however, it is not limited to the transportation mechanism having such a configuration, and may have a configuration in which the recording medium is transported by being supported with a movable supporting tray, or the like, or a configuration in which the recording medium is transported by a pair of rollers, or the like. Also, a so called flatbed type recording apparatus may be used, which performs recording by fixing the recording medium to the supporting portion and moving the recording head 7 to a fixed recording medium.
The recording mechanism 4 includes a carriage motor 30 (refer to Fig. 8) which reciprocates the carriage 6 including the recording head 7 capable of discharging ink (liquid) in the reciprocating direction B.
The recording apparatus 1 of the example performs recording by reciprocally scanning the carriage 6 including the recording head 7 at the time of recording; however, during record-scanning (during moving of carriage 6), the transportation mechanism 3 allows transportation of the recording medium to stop. When expressed in a different manner, at the time of recording, reciprocal scanning of the carriage 6 and transportation of the recording medium are alternately performed. That is, at the time of recording, corresponding to reciprocal scanning of the carriage 6, the transportation mechanism 3 intermittently transports the recording medium (the adhesive belt 2 is intermittently moved).
Moreover, a rail 10a extending in the reciprocating direction B is provided on a pipe 11a constituting a frame portion of the recording apparatus 1 of the example, and a rail 10b extending in the reciprocating direction B is provided on a pipe 11b constituting the frame portion of the recording apparatus 1 of the example. In addition, bearing portions (not illustrated) are received in the rail 10a and the rail 10b, and thus, the carriage 6 of the example is guided to move in the reciprocating direction B by the rail 10a and the rail 10b.
In addition, as illustrated in Fig. 3, the recording mechanism 4 of the example is divided into a moving region 18 of the carriage 6, an airflow receiving chamber 13 to be described later, and a cable accommodating portion 36 which accommodates cables, or the like for transmitting data and signals to the carriage 6 by the case body 12 and a wall portion 16. Also, by such a configuration, the mist, which is generated when the ink is discharged from the recording head 7 in the moving region 18 of the carriage 6, can be moved to the airflow receiving chamber 13, and an invasion of the mist into the cable accommodating portion 36 is suppressed.
Next, the carriage 6 of the recording apparatus 1 of the example will be described.
Fig. 4 to Fig. 7 illustrates schematic views of the carriage 6 of the example. Among these, Fig. 4 is a schematic perspective view of the carriage 6 of the example, Fig. 5 is a schematic plan view of the carriage 6 of the example, Fig. 6 is a schematic front view of the carriage 6 of the example, and Fig. 7 is a schematic side view of the carriage 6 of the example.
Moreover, in the carriage 6 of the example, sub-carriages 5 including a plurality of the recording heads 7 are provided in multiple (six), and Fig. 4 and Fig. 5 are perspective views illustrating an arrangement of the plurality of recording heads 7 provided in each of the sub-carriages 5.
As illustrated in Fig. 5 and Fig. 6, the plurality (six) of sub-carriages 5 can be detachable to the carriage 6 of the example. As illustrated in Fig. 4 and Fig. 5, in each of the sub-carriages 5, the plurality of recording heads 7 are alternately arranged from each other (staggered). Moreover, in addition to the plurality of recording heads 7, a substrate, and the like are provided in each of the sub-carriages 5, and as illustrated in Fig. 6, a sub-carriage fan 21 for cooling the substrate is provided therein.
Since the sub-carriage fan 21 suppresses an increase of a temperature inside the sub-carriage 5 by sending (blowing) the air to an inside of the sub-carriage 5, when there is mist of the ink in the vicinity of the sub-carriage fan 21, the mist is sent to the inside of the sub-carriage 5, and thus there is a concern that the mist is attached to the substrate, and the like.
For this reason, in the recording apparatus 1 of the example, in order to suppress attaching of the mist to the substrate, and the like, as described above, the mist can be moved from the moving region 18 of the carriage 6 to the airflow receiving chamber 13.
In addition, a frame type portion 37, which is for suppressing the mist of the ink discharged from the recording head 7 from flying up and the mist from becoming attached to the sub-carriage 5, is provided. The frame type portion 37 functions as a separator which suppresses flying-up of the mist with respect to a region where the mist near the recording head 7 is profuse and keeps a region above the sub-carriage 5 in a state where the mist is small.
Further, air current generation portions 38a and 38b in which a carriage fan 20 is respectively provided are provided in an outside of the frame type portion 37 in the reciprocating direction B. When expressed in a different manner, in the air current generation portions 38a and 38b provided on the outside of the frame type portion 37 in the reciprocating direction B, the carriage fan 20, which generates air current toward an opening portion 40 provided at an upstream side of the transportation direction A, is provided in the vicinity of an opening portion 39 which is provided at a downstream side of the transportation direction A.
Here, the carriage 6 of the example drives the carriage fan 20, thereby making it possible to move the mist to a position (upstream side of transportation direction A) which does not overlap with the recording head 7 in a moving region 18 of the carriage 6 when seen in the reciprocating direction B, by a control of the controller 23, during recording (during discharging the ink from the recording head 7 while moving the carriage 6 in the reciprocating direction B).
Such a carriage 6 of the example is provided with the frame type portion 37 and the air current generation portions 38a and 38b, and particularly, has a configuration hardly affected by the mist. However, the invention is not limited to the recording apparatus including the carriage which has such a configuration.
Next, an electrical configuration in the recording apparatus 1 of the example will be described.
Fig. 8 is a block diagram of the recording apparatus 1 of the example.
In the controller 23, a CPU 24 which controls the entire recording apparatus 1 is provided. The CPU 24 is connected to a ROM 26 which stores various programs, and the like executed by the CPU 24 and a RAM 27 which is capable of temporary storing data through a system bus 25.
In addition, the CPU 24 is connected to a head driving portion 28 for driving the recording head 7 through the system bus 25.
In addition, the CPU 24 is connected to a motor driving portion 29, which is for driving the carriage motor 30, a transportation motor 31, a feeding motor 32, a winding motor 33, a carriage fan motor 19, and a sub-carriage fan motor 22, through the system bus 25.
Here, the carriage motor 30 is a motor for moving the carriage 6 including the recording head 7. In addition, the transportation motor 31 is a motor for driving the driving roller 8. In addition, the feeding motor 32 is a driving motor of the feeding portion for feeding the recording medium which is set in a feeding portion (not illustrated) to the transportation mechanism 3. In addition, the winding motor 33 is a driving motor for driving a winding mechanism (not illustrated) which is for winding the recording medium on which recording is performed. In addition, the carriage fan motor 19 is a motor for driving the carriage fan 20. Also, the sub-carriage fan motor 22 is a motor for driving the sub-carriage fan 21.
Further, the CPU 24 is connected to an input and output portion 34 through the system bus 25, and the input and output portion 34 is connected to a PC 35 for performing transmitting and receiving of data such as recording data and a signal.
Next, the airflow receiving chamber 13 which is a main part of the recording apparatus 1 of the example will be described.
Here, Fig. 9 is a schematic perspective view illustrating the moving region 18 and the airflow receiving chamber 13 of the carriage 6 which are parts of the recording mechanism 4 of the recording apparatus 1 of the example. In addition, Figs. 10A and 10B are schematic front views illustrating the moving region 18 and the airflow receiving chamber 13 of the carriage 6 which are parts of the recording mechanism 4 of the recording apparatus 1 of the example. Moreover, Fig. 10A is a view illustrating airflows W1 in the moving region 18 and the airflow receiving chamber 13 of the carriage 6 when the carriage 6 is moved in a direction B1 of the reciprocating direction B, and Fig. 10B is a view illustrating airflows W2 in the moving region 18 and the airflow receiving chamber 13 of the carriage 6 when the carriage 6 is moved in a direction B2 of the reciprocating direction B.
As illustrated in Fig. 9, in the moving region 18 of the carriage 6, the carriage 6 of the example is capable of moving the carriage 6 in a moving range R1 from the position P1 to the position P2 in the reciprocating direction B. Also, the recording apparatus 1 of the example includes a case body 12 which covers the moving region 18 of the carriage 6, and includes the airflow receiving chamber 13 which is capable of receiving the airflow W1 pushed from the moving region 18 of the carriage 6 by moving the carriage 6 in the direction B1 as illustrated in Fig. 10A. Moreover, the airflow receiving chamber 13 is also capable of receiving the airflow W2 pushed from the moving region 18 of the carriage 6 by moving the carriage 6 in the direction B2 as illustrated in Fig. 10B.
That is, the recording apparatus 1 of the example includes the carriage 6 which includes the recording head 7 discharging the ink onto a recording medium and can be moved in the reciprocating direction B and the airflow receiving chamber 13 which receives the airflow W1 and the airflow W2 generated by reciprocating the carriage 6.
For this reason, since the recording apparatus 1 of the example has such a configuration, that is, a simple configuration in which the airflow receiving chamber 13 is included, the mist generated when the ink is discharged from the recording head 7 can be moved from the moving region 18 of the carriage 6 using the airflow W1 and the airflow W2 generated due to reciprocation of the carriage 6.
Moreover, as in the recording apparatus 1 of the example, "covering the moving region 18 of the carriage 6" means that other parts may be covered when at least the moving region 18 of the carriage 6 is covered, but it does not need to be covered in a sealed state.
In addition, as illustrated in Figs. 10A and 10B, the airflow receiving chamber 13 of the example extends in the reciprocating direction B, and a receiving port 49 of the airflow W1 and the airflow W2 is provided on both ends of the reciprocating direction B. That is, with such a configuration, the airflow receiving chamber 13 of the example can receive the airflow W1 and the airflow W2 from the receiving ports 49 of both ends in the moving directions B1 and B2 of both sides in the reciprocating direction B. For this reason, the mist generated when the ink is discharged from the recording head 7 can be efficiently moved from the moving region 18 of the carriage 6.
In addition, as illustrated in Fig. 9 to Fig. 10B, the airflow receiving chamber 13 of the example includes a capturing portion 17, which is capable of capturing the mist generated when the ink is discharged from the recording head 7 in the vicinity of the receiving ports 49 of both ends in the reciprocating direction B. Therefore, the mist moved from the moving region 18 of the carriage 6 can be captured and recovered by the capturing portion 17.
Moreover, the capturing portion 17 of the example is a filter which is capable of capturing the mist by transmitting the airflow and is configured to have a filter type which is fixed to the airflow receiving chamber 13; however, if the mist can be captured, a configuration of the capturing portion 17 is not particularly limited. Moreover, the filter described above is an absorbing member which is capable of absorbing the attached liquid.

Example 2 (Figs. 11A and 11B)

Next, the recording apparatus according to Example 2 of the invention will be described.
Figs. 11A and 11B are schematic perspective views illustrating the recording mechanism 4 of the recording apparatus 1 according to Example 2 of the invention. Fig. 11A corresponds to Fig. 10A illustrating the recording mechanism 4 of the recording apparatus 1 according to Example 1, and Fig. 11B corresponds to Fig. 10B illustrating the recording mechanism 4 of the recording apparatus 1 according to Example 1.
Moreover, configuration members common to those of Example 1 are illustrated by the same numerals, and detailed descriptions thereof will not be repeated.
In the recording apparatus 1 of the example, only a configuration of the airflow receiving chamber 13 which is a main part of the recording apparatus 1 of the example is different from the recording apparatus 1 of Example 1.
As illustrated in Figs. 10A and 10B, the airflow receiving chamber 13 of Example 1 is configured to have the capturing portion 17 which is a filter type fixed to airflow receiving chamber 13.
Meanwhile, the airflow receiving chamber 13 of Example 2 is configured to have a plurality of flexible filters (absorbing members), in which a part (upper portion) thereof is fixed inside of the airflow receiving chamber 13 and is hanging inside of the airflow receiving chamber 13 as illustrated in Figs. 11A and 11B. For this reason, the capturing portion 17 of the example can change a posture thereof by the airflow W1 and the airflow W2, and does not shield the airflow W1 and the airflow W2 generated by reciprocation of the carriage 6 inside of the airflow receiving chamber 13. That is, the recording apparatus 1 of the example efficiently receives the airflow W1 and the airflow W2 including the mist from the moving region 18 of the carriage 6 in the airflow receiving chamber 13, and the mist can be captured and recovered in the airflow receiving chamber 13.
Moreover, the airflow receiving chamber 13 of the example is configured to have the plurality of flexible filters in both end parts of the reciprocating direction B; however, it is not limited to such a configuration, and the flexible filters may be provided on the entirety of the inside of the airflow receiving chamber 13, for example, and flexible filters may be provided in which a center part in the reciprocating direction B has a density higher than that of both of the end parts thereof.

Example 3 (Figs. 12A and 12B)

Next, a recording apparatus according to Example 3 of the invention will be described.
Figs. 12A and 12B are schematic perspective views illustrating the recording mechanism 4 of the recording apparatus 1 according to Example 3 of the invention. Fig. 12A corresponds to Fig. 10A illustrating the recording mechanism 4 of the recording apparatus 1 of the Example 1, and Fig. 12B corresponds to Fig. 10B illustrating the recording mechanism 4 of the recording apparatus 1 of the Example 1.
Moreover, configuration members common to those of Example 1 and Example 2 are illustrated by the same numerals, and detailed descriptions thereof will not be repeated.
The recording apparatus 1 of the example has a configuration of the airflow receiving chamber 13, which is a main part of the recording apparatus 1 of the example, different from the recording apparatus 1 of Example 1 and Example 2.
As illustrated in Figs. 10A and 10B, in the airflow receiving chamber 13 of Example 1, it is possible that the airflow W1 and the airflow W2 flows-in from the end portions of one side of the reciprocating direction B and the airflow W1 and the airflow W2 flows-out from the end portions of the other side of the reciprocating direction B.
Meanwhile, as illustrated in Figs. 12A and 12B, the airflow receiving chamber 13 of the example is connected to a duct 41 connected to the outside of the recording apparatus 1, and the airflow W1 and the airflow W2 can be exhausted through the duct 41. Moreover, only that point described above is different from the recording apparatus 1 of Example 1. For this reason, the airflow W1 and the airflow W2 extruded from the moving region 18 of the carriage 6 by moving the carriage 6 is easily received, and the airflow W1 and the airflow W2 generated by reciprocation of the carriage 6 can be efficiently received in a airflow receiving chamber 13. Naturally, Example 2 can be modified in a similar way.

Example 4 (Figs. 13A and 13B)

Next, a recording apparatus according to Example 4 of the invention will be described.
Figs. 13A and 13B are schematic perspective views illustrating the recording mechanism 4 of the recording apparatus 1 according to Example 3 of the invention. Fig. 13A corresponds to Fig. 10A illustrating the recording mechanism 4 of the recording apparatus 1 of the Example 1, and Fig. 13B corresponds to Fig. 10B illustrating the recording mechanism 4 of the recording apparatus 1 of the Example 1.
Moreover, configuration members common to that of Example 1 to Example 3 are illustrated by the same numerals, and detailed descriptions thereof will not be repeated.
The recording apparatus 1 of Example 4 only has the configuration of the airflow receiving chamber 13 which is a main part of the recording apparatus 1 of the example, and a part of the configuration of the case body 12 are different from that the recording apparatus 1 of Example 1 to Example 3.
As illustrated in Figs. 10A and 10B, the airflow receiving chamber 13 of Example 1 to Example 3 includes the capturing portion 17 which is capable of capturing the mist generated when the ink is discharged from the recording head 7.
Meanwhile, as illustrated in Figs. 13A and 13B, the airflow receiving chamber 13 of the example includes a back-flow preventing portion 42 instead of the capturing portion 17. For this reason, back-flowing of the airflow W1 and the airflow W2 including the mist in the moving region 18 of the carriage 6 from the airflow receiving chamber 13 can be suppressed.
Moreover, the back-flow preventing portion 42 of the example includes a rotation shaft 43 of a direction along a transportation direction A, a lid portion 44 which can be rotated in a rotation direction C around the rotation shaft 43, and a regulating member 45 which regulates turning of the lid portion 44 in a direction from the inside toward the outside of the airflow receiving chamber 13. In addition, the airflow W1 and the airflow W2 flow inside the airflow receiving chamber 13 by turning the lid portion 44 inside of the airflow receiving chamber 13, and flowing-out of the airflow W1 and the airflow W2 to the outside of the airflow receiving chamber 13 is suppressed by regulating the lid portion 44 using the regulating member 45. However, a configuration of the back-flow preventing portion 42 is not particularly limited. In addition, of course, the capturing portion 17 may be provided inside of the airflow receiving chamber 13.
In addition, in the moving region 18 of the carriage 6 in the case body 12 of the recording apparatus 1 of the example, an airflow inflow portion 46 in which airflow W3 and airflow W4 can flow therein through a path different from the airflow receiving chamber 13 is provided. That is, the recording apparatus 1 of the example is capable of generating the airflow W3 from the airflow W1 in a direction in an order of the airflow inflow portion 46, the moving region 18 of the carriage 6, and the airflow receiving chamber 13. For this reason, the recording apparatus 1 of the example is capable of efficiently moving the mist generated when the ink is discharged from the recording head 7 from the moving region 18 of the carriage 6.
Moreover, the airflow inflow portion 46 of the example includes the rotation shaft 47 along the transportation direction A and the lid portion 48 capable of being rotated in the rotation direction C around the rotation shaft 47 as a reference Turning of the lid portion 48 from the inside of the airflow inflow portion 46 toward the outside is regulated by a part of the case body 12. In addition, the airflow W3 and the airflow W4 flows-in on the inside of the airflow inflow portion 46 by turning the lid portion 48 inside of the airflow inflow portion 46, and flowing-out of the airflow W3 and the airflow W4 to the outside of the airflow inflow portion 46 is suppressed by regulating the lid portion 48 using a part of the case body 12. However, a configuration of the airflow inflow portion 46 is not particularly limited.
Moreover, the invention is not limited to the above examples, and can be variously modified within a range of the invention disclosed in the claims. It is needless to say that these are also included in the range of the invention.
Hitherto, the invention has been described on the basis of the specific examples. Here, an outline of the invention will be described again.
