JP 2013-158964 A

  In such a printer, a pair of members that suppress deformation and bending of the base frame, support an extending member (shaft) that extends in parallel along the moving direction of the print head, and improve the positional accuracy of each part of the printer. Side frames are provided. However, the side frame of the printer of Patent Document 1 is provided between a printing area where printing is performed on a recording medium and a maintenance area where a cap unit (maintenance unit) is provided, and a base frame is printed on the side frame. A through hole penetrating from the region to the maintenance region was provided. In this configuration, there is a possibility that the rigidity of the side frame may be reduced due to the through hole provided in the side frame. Further, when the side frames are provided at both ends of the base frame, that is, outside the maintenance area, the distance between the side frames is widened. As a result, there is a problem that the shaft and base frame supported by the side frames are long and the mass of the printer is heavy.

  SUMMARY An advantage of some aspects of the invention is to solve at least a part of the problems described above, and the invention can be implemented as the following forms or application examples.

  Application Example 1 A printer according to this application example includes a print head, a carriage that moves the print head to a position that faces a platen that supports a medium, and a position that faces a cap portion that protects the print head. A pair of side frames that support the first shaft and the second shaft, and a base that supports the platen supported by at least the first side frame in contact with the first surface of the first side frame of the pair of side frames. And a support frame that is supported by at least the first side frame in contact with the second surface of the first side frame and supports the cap portion.

  According to this application example, the printer includes a pair of side frames, a base frame that supports the platen, and a support frame that supports the cap portion. That is, the cap portion is supported by a support frame different from the base frame on which the platen is supported. The base frame is in contact with the first surface of the first side frame of the pair of side frames. The support frame is in contact with the second surface of the first side frame. According to this configuration, it is not necessary to provide a through hole in the first side frame. Further, the first side frame can be disposed between the printing area where the platen is provided and the maintenance area where the cap portion is provided in the moving direction of the print head. Accordingly, it is possible to prevent the first and second shafts and the base frame from becoming long, and to improve the rigidity of the first side frame. Therefore, it is possible to provide a printer that is lighter by improving the rigidity of the side frame.

  Application Example 2 In the printer according to the application example described above, it is preferable that the base frame and the first side frame constitute a part of a suction chamber that adsorbs the medium to the platen.

  According to this application example, since the base frame and the first side frame constitute a part of the suction chamber, members for configuring the suction chamber can be reduced. In addition, by making the first side frame a part of the suction chamber, the platen can be disposed adjacent to the first side frame. The maintenance area where the print head faces the cap portion is the home position of the print head. Since the time required for the print head to reciprocate between the home position and the print area facing the platen is shortened, the print processing time (throughput) of the printer is improved.

  Application Example 3 In the printer according to the application example described above, it is preferable that a second side frame different from the first side frame among the pair of side frames constitutes a part of the suction chamber.

  According to this application example, the second side frame constitutes a part of the suction chamber. That is, since the suction chamber is composed of the first and second side frames and the base frame, the members for configuring the suction chamber can be further reduced.

  Application Example 4 In the printer according to the application example described above, it is preferable that the base frame includes a fan that makes the suction chamber have a negative pressure, and a communication hole that communicates with the fan.

  According to this application example, the communication hole communicating with the fan for setting the suction chamber to a negative pressure is provided in the base frame. Thereby, it is not necessary to provide a communication hole in the side frame, so that the rigidity of the side frame can be improved.

  Application Example 5 In the printer according to the application example described above, it is preferable that the communication hole is provided on a base frame other than a vertically lower surface.

  According to this application example, since the communication hole is provided on a surface other than the surface below the vertical direction of the base frame, it is possible to prevent ink from leaking from the suction chamber to the outside even when ink leakage occurs.

  Application Example 6 In the printer according to the application example described above, the first axis is a carriage shaft that slidably supports the carriage, and the second axis conveys the medium along a conveyance path. It is preferable that it is a spindle of the conveyance roller to be made.

  According to this application example, the first shaft is a carriage shaft, and the second shaft is a support shaft of the transport roller. Since the carriage shaft and the support shaft of the transport roller are supported by a side frame with improved rigidity, the relative positional accuracy between the medium transported to the transport roller and the print head mounted on the carriage is improved. Improved print quality.

  Application Example 7 In the printer according to the application example described above, it is preferable that the first shaft and the second shaft are support shafts of a transport roller that transports the medium along a transport path.

  According to this application example, the first shaft and the second shaft are both support shafts of the transport roller. Since the support roller support shaft is supported by a side frame with improved rigidity, the relative positional accuracy of the plurality of transport rollers provided in the transport path for transporting the medium is improved, and the medium may be skewed. Is reduced.

Further, a liquid storage unit 15 is provided at one end (right end in FIG. 1) of the front surface of the housing 12 in the longitudinal direction. The liquid storage unit 15 is configured to be detachable from a liquid storage body (not shown) that stores ink such as magenta, cyan, yellow, and black.

  As shown in FIGS. 2 and 3, the printer 11 includes a transport unit 25 that transports the medium M in the transport direction Y <b> 1 and a printing unit 30 that performs printing on the medium M. A control unit 50 that controls the operation of each component is provided.

  The printing unit 30 includes a print head 31 that ejects ink toward the medium M, a carriage 32 that holds the print head 31 and moves it in the width direction (X-axis direction) of the medium M, and a platen 35 that supports the medium M. ing. The print head 31 includes a plurality of nozzles (not shown) and is configured to eject ink. The printing unit 30 includes a first axis that extends along the movement direction (X-axis direction) of the print head 31. The first axis of the present embodiment is a carriage main shaft 33 as a carriage shaft that slidably supports the carriage 32. That is, the carriage 32 supported by the carriage main shaft 33 is slidable with respect to the carriage main shaft 33.

  The carriage 32 holding the print head 31 is supported by a carriage main shaft 33 and a carriage sub shaft 34 extending in parallel to the carriage main shaft 33. The carriage 32 reciprocates the print head 31 along the width direction (X-axis direction) of the medium M by the power of the carriage drive motor 36. The platen 35 is provided with a substantially rectangular surface with the width direction (X-axis direction) of the medium M as the longitudinal direction on the upper surface facing the print head 31. The medium M is supported by the platen 35 while being adsorbed on the upper surface of the platen 35 by the negative pressure applied to the platen 35. Thereby, a decrease in print quality due to the floating of the medium M is reduced. In the present embodiment, a configuration in which the carriage 32 is supported by the two shafts of the carriage main shaft 33 and the carriage auxiliary shaft 34 is shown, but a configuration in which the carriage is supported by one shaft or a rail member is supported. It may be configured.

The transport driving roller is positioned upstream of the printing unit 30 in the transport direction Y1 of the medium M. The transport unit 25 includes a second shaft as the transport roller shaft 23 that is a support shaft of the transport drive roller 24. The conveyance roller shaft 23 extends along the moving direction (X-axis direction) of the print head 31. Further, the transport roller shaft 23 is longer than the width of the medium M used in the printer 11 in the X-axis direction.

  The transport unit 25 includes a transport driven roller 26 and a transport guide roller 27. The conveyance guide roller 27 guides the medium M fed from the feeding unit 20 above the housing 12 to the printing unit 30 side in the conveyance path. The conveyance driven roller 26 is pressed toward the conveyance driving roller 24 and is driven to rotate by the conveyance driving roller 24. The transport driving roller 24 sandwiches the medium M with the transport driven roller 26, and the transport driving roller 24 is rotationally driven by a roller driving motor (not shown), so that the medium M is transported in the transport direction Y1. In the present embodiment, two transport driving rollers 24 are provided on the upstream side and the downstream side of the transport guide roller 27.

  By repeating the ejection operation in which the printing unit 30 ejects ink from the print head 31 to the medium M while reciprocating the carriage 32 in the X-axis direction, and the conveyance operation in which the conveyance unit 25 conveys the medium M in the conveyance direction Y1. Images, characters, etc. are printed on the medium M. A cutter frame 28 is provided inside the housing 12. The cutter frame 28 is provided on the downstream side of the printing unit 30 in the conveyance path of the medium M. By sliding the cutter along the cutter frame 28, the medium M printed by the printing unit 30 is cut into a predetermined size.

  As shown in FIGS. 3 and 4, the printer 11 includes a maintenance unit 60 that performs maintenance on the print head 31. The maintenance unit 60 is provided on one side of the platen 35 (in this embodiment, the negative side in the X-axis direction) in the width direction (X-axis direction) of the medium M in which the print head 31 reciprocates. The maintenance unit 60 is installed at a position overlapping the print head 31 that reciprocates along the X-axis direction in the Z-axis direction. That is, the carriage 32 (print head 31) is positioned at a position facing the platen 35 that supports the medium M (print region) and a position facing the maintenance unit 60 including the cap portion 61 that protects the print head 31 (maintenance region). It is configured to be movable.

  The maintenance unit 60 includes a cap unit 61, a wiping unit 62 that removes ink, and a flushing unit 63 that receives ink ejected from the nozzles of the print head 31.

FIG. 4 shows a state in which the cap unit 61 is in contact with the print head 31.

<Frame configuration>
Next, the configuration of the frame to which each unit described above is connected will be described.
The frame of the printer 11 includes a pair of side frames (first and second side frames 41 and 42), a base frame 51, and a support frame 43.

  The first and second side frames 41 and 42 are plate-like members. In the longitudinal direction (X-axis direction) of the housing 12, the first side frame 41 is located on the right side (−side in the X-axis direction) of the housing 12. The second side frame 42 is located on the left side (+ side in the X-axis direction) of the housing 12. The first side frame 41 and the second side frame 42 face each other.

  The base frame 51 is supported by at least the first side frame in a state where it is in contact with the first surface (the + side surface in the X-axis direction) 41 a of the first side frame 41. The base frame 51 supports the platen 35. The base frame 51 has a hollow quadrangular prism shape. In the present embodiment, one end of the base frame 51 is in contact with the first surface 41a of the first side frame 41, and the other end of the base frame 51 is the second surface of the second side frame 42 (on the negative side in the X-axis direction). Surface) 42b. Since the platen 35 is provided on the upper surface (the surface on the negative side in the Z-axis direction) of the base frame 51, the first side frame 41 is located at one end of the printing region in which the platen 35 is provided in the X-axis direction. The second side frame 42 is located at the other end of the printing area in the X-axis direction.

  The support frame 43 is supported by at least the first side frame in contact with the second surface 41 b of the first side frame 41. The support frame 43 supports the maintenance unit 60 including the cap portion 61. The maintenance unit 60 is provided on a support frame 43 that is separate from the base frame 51 that supports the platen 35. The support frame 43 protrudes from the second surface 41 b of the first side frame 41 toward the − side in the X-axis direction. That is, the first side frame 41 is provided between the printing area and the maintenance area in which the maintenance unit 60 is provided in the X-axis direction. The support frame 43 has a pair of wall portions that face each other in the Y-axis direction and gradually decrease in length in the Z-axis direction toward the tip (−side in the X-axis direction), and the pair of wall portions in the Y-axis direction. A maintenance unit 60 is provided in between. According to this configuration, a wide area where the support frame 43 contacts the first side frame 41 is ensured, and the support frame 43 is reduced in weight, so that the positional accuracy of the maintenance unit 60 is improved.

  In the case of a printer having a conventional configuration in which the maintenance unit 60 is supported on the base frame 51, the first side frame 41 needs a through hole through which the base frame 51 is penetrated. The maintenance unit 60 can be supported without being provided. Thereby, the rigidity of the first side frame 41 is improved. Further, since the second side frame 42 is connected to the first side frame 41 with increased rigidity via the base frame 51, the rigidity of the second side frame 42 is also improved. Further, the length of the heavy base frame 51 is shorter than when the first side frame 41 is provided outside the maintenance unit 60 (the negative side in the X-axis direction), so that the printer 11 can be reduced in weight. it can.

  The first and second side frames 41 and 42 support a carriage main shaft 33 as a first shaft and a transport roller shaft 23 as a second shaft. One end of the transport roller shaft 23 is in contact with the first surface 41 a of the first side frame 41, and the other end of the transport roller shaft 23 is in contact with the second surface 42 b of the second side frame 42. Since the first side frame 41 of the present embodiment is provided between the printing area and the maintenance area in the X-axis direction, the first side frame 41 is located outside the maintenance unit 60 (− side in the X-axis direction). Compared with the case where it is provided, the length of the transport roller shaft 23 can be shortened. In addition, the carriage main shaft 33 and the transport roller shaft 23 are supported by at least one of the first side frame 41 and the second side frame 42 with improved rigidity, so that the medium M transported to the transport drive roller 24 and The relative positional accuracy with the print head 31 mounted on the carriage 32 is improved, and the print quality of the printer 11 is improved.

  In addition, one end of the carriage main shaft 33 is connected to a subframe 44 that protrudes from the first side frame 41 to the outside of the maintenance unit 60 (the negative side in the X-axis direction), and the other end of the carriage main shaft 33 is connected to the second side frame. In contact with the second surface 42b. Thereby, the carriage 32 holding the print head 31 can be moved to the maintenance area.

  The base frame 51 and the first side frame 41 constitute a part of the suction chamber 52 that adsorbs the medium M to the platen 35. Further, the second side frame 42 constitutes a part of the suction chamber 52. That is, the suction chamber 52 of the present embodiment includes the base frame 51, the first side frame 41, and the second side frame 42. Openings at both ends of the square columnar base frame 51 having a hollow structure are closed by connecting the base frame 51 to the first and second side frames 41 and 42. Thereby, the inside of the base frame 51 is a closed space. And the suction chamber 52 which has airtightness is comprised by apply | coating a sealing material to a connection part.

  In the case of a conventional printer, since one opening of the base frame 51 passes through the first side frame 41, it is difficult to make the inside of the base frame 51 a closed space. For this reason, it is necessary to provide a separate suction chamber in the base frame 51 or to provide a member for closing the opening of the base frame 51. Since the base frame 51 and the first side frame 41 of the present embodiment constitute a part of the suction chamber 52, the members for providing the suction chamber can be reduced and the manufacturing cost of the printer 11 can be reduced. Further, since the second side frame 42 constitutes a part of the suction chamber 52, the members for providing the suction chamber can be further reduced.

  In the present embodiment, the first side frame 41 is used as a part of the suction chamber 52 by arranging the first side frame 41 between the printing area and the maintenance area. For this reason, the platen 35 serving as a printing region can be arranged in a state adjacent to the first side frame 41 in the X-axis direction. In other words, the distance in the carriage scanning direction between the printing area and the maintenance area can be shortened. Further, the maintenance area is a home position where the print head 31 is located during non-printing. Thereby, when printing is performed, the movement time for the print head 31 to reciprocate between the home position and the print area is shortened, so that the print processing time (throughput) of the printer 11 is improved.

  The printer 11 includes a fan 55 that makes the suction chamber 52 have a negative pressure. A communication hole 53 that communicates with the fan 55 is provided in the base frame 51. As a result, it is not necessary to provide the communication hole 53 for sucking the suction chamber 52 in either the first side frame 41 or the second side frame 42, so that the first side frame 41 or the second side frame 42 Stiffness is improved.

  The suction chamber 52 communicates with the fan 55 through the communication hole 53. The suction chamber 52 and the platen 35 communicate with each other through a plurality of pores (not shown). When the fan 55 is driven to rotate, a negative pressure is applied to the platen 35 through the suction chamber 52. As a result, the medium M is adsorbed on the upper surface of the platen 35.

  The communication hole 53 is provided on a surface of the base frame 51 other than the surface below the vertical direction (+ side in the Z-axis direction). For example, when the communication hole 53 is provided in the vertically lower surface of the base frame 51, when ink leaks, the leaked ink is transmitted from the platen 35 to the suction chamber 52 and leaks from the communication hole to the outside. There is a risk of it. Further, the leaked ink may be transmitted to the fan 55 and cause a failure of the fan 55. Since the communication hole 53 of this embodiment is provided on the front surface (+ side in the Y-axis direction) of the base frame 51, it is possible to prevent ink from leaking to the outside and the fan 55 from being damaged. Ink leakage to the suction chamber 52 occurs, for example, when ink ejected to a borderless printing absorbing member arranged in the platen 35 enters a plurality of pores provided in the platen 35.

  In the present embodiment, it has been described that the first axis is the carriage main shaft 33 and the second axis is the transport roller shaft 23. However, both the first axis and the second axis pass the medium M along the transport path. The conveyance roller shaft 23 to be conveyed may be used. Since the transport roller shaft 23 is supported by the first and second side frames 41 and 42 with improved rigidity, the relative positional accuracy of the plurality of transport drive rollers 24 provided in the transport path through which the medium M is transported. Therefore, the possibility that the medium M is skewed is reduced.

  Further, one of the first axis and the second axis may be the cutter frame 28. Thereby, since the relative positional accuracy of the medium M conveyed to the conveyance drive roller 24 and the cutter frame 28 is improved, the cutting accuracy of the medium M is improved.

  Further, the first shaft and the second shaft may be support shafts of various rollers that contribute to the conveyance of the medium M. Thereby, the medium M can be conveyed suitably.

  Further, in the present embodiment, the spindle 22 inserted through the core member around which the medium M is wound is described as being mounted on the roll body holding unit 21, but the spindle 22 is supported by the pair of side frames 41 and 42. It may be a configuration. One of the first axis and the second axis may be the spindle 22.

As described above, according to the printer 11 according to the present embodiment, the following effects can be obtained.
The maintenance unit 60 of the printer 11 is provided on a support frame 43 that is separate from the base frame 51 that supports the platen 35. According to this configuration, it is not necessary to provide the first side frame 41 with a through hole that allows the base frame 51 to pass therethrough, so that the rigidity of the first side frame 41 is improved. Further, since the length of the heavy base frame 51 is shortened, the printer 11 can be reduced in weight. Thereby, the printer 11 which improved the rigidity of the side frame and achieved weight reduction can be provided.

  The base frame 51 and the first side frame 41 constitute a part of the suction chamber 52. According to this, since the member for providing a suction chamber is reduced, the weight reduction of the printer 11 and the manufacturing cost reduction of the printer 11 are realizable. Further, since the second side frame 42 constitutes a part of the suction chamber 52, the members for providing the suction chamber can be further reduced.

  Since the first side frame 41 constitutes a part of the suction chamber 52, the platen 35 serving as a printing area can be disposed adjacent to the first side frame 41. As a result, the time required for the print head 31 to reciprocate between the home position (maintenance area) and the print area is shortened, so that the print processing time (throughput) of the printer 11 is improved.

  The printer 11 includes a fan 55 that makes the suction chamber 52 have a negative pressure. A communication hole 53 that communicates with the fan 55 is provided in the base frame 51. This eliminates the need to provide the communication hole 53 for sucking the suction chamber 52 in either the first side frame 41 or the second side frame 42, so that the first side frame 41 or the second side frame 42 Stiffness is improved.

  Since the communication hole 53 is provided on a surface of the base frame 51 other than the surface below the vertical direction (+ side in the Z-axis direction), ink leaks to the outside of the base frame 51 or the fan 55 is damaged due to the leaked ink. Can be prevented.

  The carriage main shaft 33 as the first shaft and the transport roller shaft 23 as the second shaft are supported by at least one of the first side frame 41 and the second side frame 42 with improved rigidity. The relative positional accuracy between the medium M conveyed to 24 and the print head 31 mounted on the carriage 32 is improved, and the print quality of the printer 11 is improved.
