JP 2009-234668 A

  However, it has been difficult for the user to determine whether or not the pressure when fitting the pair of holders into the core opening of the roll core of the roll paper is sufficiently large. The heavier the roll paper, the greater the pressure needs to be. Moreover, the magnitude | size of the said required pressure changes with shapes of the part fitted on both sides of roll paper. If the pressure is not appropriate, the roll paper may drop or the end of the roll paper may be damaged.

  SUMMARY OF THE INVENTION The present invention has been made in view of such a situation, and the problem is that a roll medium holder device and a roll that take into account that the fitting portion is fitted and held appropriately in the core opening of the roll core of the roll medium. It is to provide a recording device having a media holder device.

  In order to achieve the above object, a roll medium holder device according to a first aspect of the present invention includes a guide portion extending in the width direction of the roll medium, and is slidable in the width direction while being guided by the guide portion. A holder portion that holds the roll medium so that the roll medium can be fed out, and the holder portion is slidable with respect to the guide portion, and is movable in the width direction with respect to the base portion. A fitting portion that fits into a core opening of a roll core of a roll medium, and an elastic body that is in contact with the fitting portion at one end side and biases the fitting portion against the base portion toward the roll medium side in the width direction. And the magnitude of the force for urging the fitting portion toward the roll medium is changed by changing the positional relationship between the one end and the other end of the elastic body, and the elastic body The positional relationship between the one end and the other end of the , The magnitude of the force the urging is characterized in that there is a mark indicating that it's predetermined size.

According to this aspect, the roll medium holder device can hold the roll medium with the predetermined size by applying pressure from both sides. That is, the user can easily confirm whether or not the magnitude of the force applied by the mark is the predetermined magnitude as compared with a configuration having no mark. In the case of a roll medium having a relatively large weight, it is effective because the roll medium holder device requires a relatively large biasing force in order to hold the roll medium properly.
The predetermined size is determined by the weight of the roll medium and the shape of the fitting portion to be press-fitted.

  The roll medium holder device according to the second aspect of the present invention includes a guide portion extending in the width direction of the roll medium, and can be slid in the width direction while being guided by the guide portion, and the roll medium can be fed out. A holder portion that is held in the base portion, and the holder portion is slidable with respect to the guide portion, and is movable in the width direction with respect to the base portion, and the core of the roll core of the roll medium A fitting portion that fits into the mouth, one end side comes into contact with the fitting portion, an elastic body that biases the fitting portion toward the roll medium side in the width direction, and another end side of the elastic body, A movable member movable in the width direction with respect to the base portion, and the fitting portion is attached to the roll medium side by changing a positional relationship between the one end and the other end of the elastic body. The magnitude of the force to be applied changes, and the fitting portion and the transfer When the positional relationship with the member in the width direction changes, and when the magnitude of the biasing force becomes a predetermined magnitude, a part of the fitting portion is aligned with a part of the moving member. It is characterized by.

  According to this aspect, the user can make the magnitude of the biasing force the predetermined magnitude by changing the positional relationship between the fitting portion and the moving member in the width direction. At this time, it is possible to confirm that the magnitude of the biasing force has reached the predetermined magnitude when a part of the fitting portion is aligned with a part of the moving member. That is, the user can easily confirm whether or not the magnitude of the biasing force is the predetermined magnitude as compared with a configuration in which a part of the fitting portion and a part of the moving member are not aligned. can do.

According to a third aspect of the present invention, in the second aspect, the present invention includes a rotatable handle and a screw mechanism that moves the moving member in the width direction by the rotation of the handle.
According to this aspect, in addition to the same effect as the second aspect, the user can increase the urging force of the elastic body by turning the handle in one direction. On the other hand, the urging force of the elastic body can be weakened by turning the handle in the opposite direction to the one. As a result, the magnitude of the urging force of the elastic body can be easily set to the predetermined magnitude as compared with a configuration having no handle. That is, even if the user does not slide the base portion with a relatively large force, the user can easily turn the handle with a relatively small force to easily increase the biasing force of the elastic body to the predetermined size. Can be.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a side sectional view showing an outline of the overall configuration of a large-sized inkjet printer 1 (hereinafter simply referred to as a printer) as a recording apparatus of the present embodiment.
As shown in FIG. 1, the printer 1 includes a medium feeding unit 26, a recording unit 28, and a winding unit 37. Among these, the medium feeding means 26 can unwind the roll medium R wound in a roll shape and feed it in the feed direction Q. Specifically, it has the 1st holder part 3 which is a sending side roll holder, and the roller pair 29. FIG.

Among these, the 1st holder part 3 can hold | maintain the both ends of the roll medium R so that rotation is possible. The first holder portion 3 has a fitting portion 13 that fits into the core opening 12 of the roll core 11 of the roll medium R. The fitting part 13 may be a rotatable structure or a structure driven by the power of a motor (not shown). This is because, in the case of the rotatable configuration, the roll medium R is pulled and unwound by the roller pair 29 driven downstream in the feed direction.
Note that a pair of first holder portions 3 are arranged facing each other. Then, at least one of the first holder portions 3 can slide in the width direction X with respect to the guide member 7 in accordance with the difference in the width dimension of the roll medium R, and the mounting position can be adjusted.

  Further, below the first holder portion 3, a temporary placement table 5 as a temporary placement portion and a lifting means 2 are provided. The temporary placement table 5 is a table for temporarily placing the roll medium R before attaching it to the first holder unit 3. As an example, the first pipe member 7 a and the second pipe member 7 b are provided to extend in the width direction X. Further, the lifting means 2 can easily lift the heavy roll medium R placed on the temporary table 5 upward, and can easily attach the end of the roll medium R to the first holder part 3.

  Specifically, the lifting means 2 includes a base portion 8 slidable in the width direction X with respect to the two first tube members 7 a and the second tube member 7 b as the guide members 7, an operation lever 6, and a lift Part 16. Then, by rotating the operation lever 6 in one direction, the elevating unit 16 is raised and the roll medium R can be lifted. On the other hand, when the operation lever 6 is rotated in the opposite direction, the elevating unit 16 is lowered and the roll medium R can be lowered. In other words, the relatively heavy roll medium R can be raised and lowered with a relatively small force by using the lever ratio of the operation lever 6.

  The recording unit 28 includes a printer main body 19. The printer main body 19 is provided with a carriage guide shaft 21 that extends in the width direction X, a carriage 23, a recording head 25, and a medium support portion 27. The carriage 23 is provided so as to be movable in the width direction X while being guided by the carriage guide shaft 21. The recording head 25 is provided at a position facing the medium support portion 27 in the carriage 23, and can record by discharging ink onto the roll medium R. Furthermore, the medium support unit 27 supports the roll medium R, and the distance between the roll medium R and the recording head 25 can be set to a predetermined distance.

Although the roller pair 29 is provided inside the printer main body 19, it may be provided outside. This is because the roll medium R only needs to be sent in the feed direction Q.
A pre-heater 31 is provided upstream of the printer main body 19 in the feed direction. This is because the ink that has landed on the roll medium R is easily dried when the recording is performed by preheating the roll medium R in a stage before the recording is performed on the roll medium R.
Furthermore, an after heater 33 is provided downstream of the printer main body 19 in the feed direction. This is because the ink landed on the roll medium R is surely dried after the recording is performed and before it is wound by the winding means 37.

  Furthermore, the winding means 37 can wind the roll medium R by the power of a motor (not shown). Specifically, it has the 2nd holder part 40 as a winding side roll holder attached to the two 3rd pipe members 39a as the guide member 39, and the 4th pipe member 39b. And the roll medium R wound up by the 2nd holder part 40 can be hold | maintained.

The printer 1 is provided at both left and right ends so as to face opposite side-view inverted T-shaped support frames 17 each having a moving caster 15 at the lower end. A printer main body 19 is provided on the support frame 17. Further, the temporary placement table 5 is attached to the sub-frame 35 attached to the support frame 17. Furthermore, both ends of the third tube member 39a and the fourth tube member 39b are held by holding portions 24 extending from the support frame 17.
Moreover, the Z-axis direction in the figure is the vertical direction.

FIG. 2 is a front view showing an outline of the overall configuration of the printer 1 of the present embodiment.
As shown in FIG. 2, the first holder part 3 is provided on the front side with respect to the support frame 17 of the printer 1, and the second holder part 40 is provided on the rear side. As described above, the first holder portion 3 is provided so as to be slidable with respect to the first tube member 7a and the second tube member 7b as the guide members 7 held at both ends by the subframe 35. Similarly, the second holder portion 40 is slidably provided with respect to the third tube member 39a and the fourth tube member 39b as the guide members 39 held at both ends by the holding portion 24.

  Here, the way of fixing the second holder part 40 to the third pipe member 39a and the fourth pipe member 39b is the same as the way of fixing the first holder part 3 to the first pipe member 7a and the second pipe member 7b. is there. Hereinafter, the structure for fixing the first holder portion 3 to the first tube member 7a and the second tube member 7b will be described, and the second holder portion 40 is fixed to the third tube member 39a and the fourth tube member 39b. Description of the structure to be fixed is omitted.

FIG. 3 is a perspective view showing the roll medium holder device 51 in the medium feeding means 26 of the present embodiment.
As shown in FIG. 3, the medium feeding means 26 includes a roll medium holder device 51. The roll medium holder device 51 includes two first tube members 7a and 2b as guide members 7 (guide portions), and a first holder portion 3 having a fitting portion 13.

  And the 1st holder part 3 is slid with respect to the 1st pipe member 7a and the 2nd pipe member 7b by rotating the knob part 36 of the screw with a knob (not shown) in the direction which loosens a screw. be able to. Specifically, the base portion 4 provided below the first holder portion 3 slides with respect to the first tube member 7a and the second tube member 7b. On the other hand, the 1st holder part 3 can be fixed with respect to the 1st pipe member 7a and the 2nd pipe member 7b by rotating to the direction which tightens a screw. Therefore, the position of the pair of first holder portions 3 can be adjusted according to the width size of the roll medium R.

  The lifting means 2 is provided between the pair of first holder portions 3 so as to be slidable with respect to the first tube member 7a and the second tube member 7b. The lifting means 2 need not be configured to be switchable between a slidable state and a fixed state with respect to the first tube member 7a and the second tube member 7b. This is because it suffices if the side end of the roll medium R can be lifted by sliding downward in the vicinity of the side end of the roll medium R in accordance with the size of the roll medium R.

Next, the roll medium holder device 51 of this embodiment will be described in detail.
FIG. 4 is a partial front sectional view showing the roll medium holder device 51 before lifting the roll medium R of this embodiment. FIG. 4 shows the first holder part 3 of one of the pair.
As shown in FIG. 4, at least one of the pair of first holder portions 3 of the roll medium holder device 51 includes a spring 42 as an example of an elastic body, a moving member 44, a shaft 47, a handle 45, a screw. And a mechanism 46.

  Among these, the spring 42 biases the fitting portion 13 toward the roll medium R with respect to the moving member 44. Here, the fitting portion 42 is provided to be slidable in the width direction X with respect to the shaft 47. The moving member 44 is configured to be movable in the width direction X with respect to the base portion 4. Specifically, the moving member 44 is engaged with an engaging portion 47a provided on the shaft 47, and can move integrally when the shaft 47 moves to the roll medium R side. Furthermore, the shaft 47 is supported by the base portion 4 so as to be slidable with respect to the base portion 4. Further, as an example, the handle 45 is provided so as to be rotatable about the width direction X as an axis. Furthermore, the screw mechanism 46 can move the shaft 47 in the width direction X by the rotation of the handle 45.

  The state shown in FIG. 4 is a state before the roll medium R is lifted. From this state, first, the roll medium R is lifted (not shown) by the other lifting means (2) opposite to the one of the pair of first holder portions 3. Then, the other first holder part (3) is slid toward the roll medium R, and the fitting part (13) of the other first holder part (3) is inserted into the core port (12) of the roll core 11. (Not shown). Further, as described above, the knob portion 36 is rotated to fix the other first holder portion (3) to the first tube member 7a and the second tube member 7b (not shown). Thereafter, as will be described later, the roll medium R is lifted by the lifting means 2 on the one side of the pair of first holder portions 3.

FIG. 5 is a partial front sectional view showing the roll medium holder device 51 when the roll medium R of the present embodiment is lifted. FIG. 5 shows the first holder portion 3 of one of the pair.
As shown in FIG. 5, as described above, after fitting the fitting portion (13) of the first holder portion (3) on the other end side into the core opening (12) of the roll core 11, the pair of first holders The roll medium R is lifted by the lifting means 2 on the one side of the part 3. And the height of the fitting part 13 of the 1st holder part 3 of the said one end side and the height of the core port 12 of the roll core 11 of the said one end side of the roll medium R are made the same.

FIG. 6 is a partial front sectional view showing a state when the roll medium holder device 51 of this embodiment is slid. FIG. 6 shows the first holder portion 3 of one of the pair.
As shown in FIG. 6, when the height of the fitting portion 13 of the first holder portion 3 on the one end side and the height of the core opening 12 of the roll core 11 on the one end side of the roll medium R are the same, the one end side The first holder part 3 is slid to the roll medium R side. Then, the fitting portion 13 of the one first holder portion 3 is fitted into the core opening 12 of the roll core 11. Here, when the fitting portion 13 can be fitted to the core opening 12 to some extent, the knob portion 36 is rotated as described above to turn the first tube member 7a and the second tube member 7b into the first first member. The holder part 3 is fixed.

FIG. 7 is a partial front sectional view showing a state when the handle 45 of the roll medium holder device 51 of this embodiment is turned. FIG. 7 shows one first holder portion 3 of the pair.
As shown in FIG. 7, the user rotates the handle 45 in the direction in which the screw is tightened. Then, the shaft 47 is pushed toward the roll medium R by the screw mechanism 46 and gradually slides with respect to the base portion 4.

  At this time, the engaging portion 47a of the shaft 47 moves the moving member 44 gradually and integrally with the base portion 4 toward the roll medium R side. Accordingly, the distance between the portion of the spring 42 in contact with the fitting portion 13 (one end 42a of the spring 42) and the portion of contact with the moving member 44 (the other end 42b of the spring 42) gradually decreases. Thereby, the magnitude | size of the force F with which the fitting part 13 is urged | biased with respect to the core port 12 of the roll core 11 of the roll medium R becomes large gradually.

  Then, the fitting portion 13 is fitted into the core opening 12 of the roll core 11 of the roll medium R. Further, when the magnitude of the biased force F gradually increases and reaches a predetermined magnitude, the width direction outer side portion 13a which is a part of the fitting portion 13 and a part of the moving member 44 are used. A certain disk portion 44 a is aligned in the width direction X. That is, it is the mark 43 when it becomes a predetermined size.

Thereby, the user can confirm that the roll core 11 of the roll medium R is held by the pair of first holder portions 3 by the force F having a predetermined magnitude.
If one of the two sides of the roll medium R is applied with a force F having a predetermined magnitude, the reaction F causes a force F having a predetermined magnitude to be applied in the opposite direction. . That is, the spring 42 may be in one of the pair of first holder parts 3. Of course, the spring 42 may be present in both of the pair of first holder portions 3.

When the user can confirm that the force F has a predetermined magnitude, the user stops the rotation of the handle 45.
Note that the screw mechanism 46 is configured so that the handle 45 does not rotate due to the reaction force of the urging force even if the handle 45 is released.
Further, when the moving member 44 enters the fitting portion 13 side too much, the user may rotate the handle 45 in the direction in which the screw is loosened. As a result, the distance between the portion of the spring 42 in contact with the fitting portion 13 (one end 42a of the spring 42) and the portion of contact with the moving member 44 (the other end 42b of the spring 42) gradually increases. This is because the magnitude of the force F with which the fitting portion 13 is urged against the core opening 12 of the roll core 11 of the roll medium R gradually decreases.

As described above, the roll medium holder device 51 can hold the roll medium R with the predetermined size by applying the pressure F from both sides. That is, the user can easily determine whether the magnitude of the biasing force F is the predetermined magnitude by aligning a part of the fitting portion 13 as the mark 43 with a part of the moving member 44. Can be confirmed. In the case of the roll medium R having a relatively large weight, since the roll medium holder device 51 requires a relatively large urging force F in order to hold the roll medium R properly, it is effective.
Further, even if the user does not slide the base portion 4 with a relatively large force, the user can easily turn the handle 45 with a relatively small force to easily increase the magnitude of the biasing force F of the spring 42 to the predetermined size. Can be.

When removing the roll medium R from the first holder part 3, the handle 45 is rotated in the direction in which the screw is loosened, then the first holder part 3 is slid outward in the width direction, and the fitting part 13 is moved to the roll core. 11 core ports 12 may be pulled out. Alternatively, the handle 45 may be rotated in the direction in which the screw is loosened after the first holder portion 3 is slid outward in the width direction and the fitting portion 13 is pulled out from the core opening 12 of the roll core 11.
Moreover, in the said Example, although the spring 42 was used as an example of an elastic body, other than the spring 42 may be sufficient. For example, elastically deformable rubber can be used.

  Furthermore, in the above embodiment, when the magnitude of the force F urged by the spring 42 reaches a predetermined magnitude, the width direction outer side portion 13a that is a part of the fitting portion 13 and the moving member 44 are However, the present invention is not limited to this. As a technical idea, the magnitude of the biasing force F is a predetermined magnitude by changing the positional relationship between the one end 42a and the other end 42b of the spring 42 (elastic body) (distance between the two). Any configuration may be used as long as it indicates that

  Moreover, although the structure which has the handle | steering-wheel 45 and the screw mechanism 46 was demonstrated in the said Example, the structure which does not have may be sufficient. As a technical idea, when the one first holder portion 3 is slid to the roll medium R side (see FIG. 6), the width direction outer side portion 13a that is a part of the fitting portion 13 is used as the mark 43. The disc portion 44a, which is a part of the moving member 44, may be used so as to be aligned in the width direction X. In other words, the handle 45 and the screw mechanism 46 are not necessarily used, and it is only necessary to have the mark 43 indicating that the magnitude of the urging force F has reached a predetermined level.

  In the above embodiment, the screw mechanism 46 is used as a mechanism for moving the moving member 44 with a relatively small force. However, as a technical idea, the moving member with a relatively small force depending on the lever ratio and the gear ratio. It is sufficient if the spring 42 can be compressed by moving 44. Accordingly, a lever mechanism or a cam mechanism may be used instead of the screw mechanism 46. The reason why the screw mechanism 46 is used in this embodiment is that it is realistic that the power can be converted by a compact mechanism as compared with a lever mechanism, a cam mechanism, or the like. Further, the position of the moving member 44 can be maintained even when the user removes his / her hand from the handle.

  The roll medium holder device 51 of the present embodiment includes a guide member 7 as a guide portion extending in the width direction X of the roll medium R, and is slidable in the width direction X while being guided by the guide member 7. A first holder part 3 that is a holder part that holds the medium R so that the medium R can be fed out. The first holder part 3 is slidable with respect to the guide member 7 and the base part 4 The fitting part 13 that can move in the width direction X and fits into the core port 12 of the roll core 11 of the roll medium R, and the one end 42a side come into contact with the fitting part 13, and the fitting part to the roll medium R side in the width direction X And a spring 42 that is an example of an elastic body that urges the base member 4 against the base portion 4, and the positional relationship between the one end 42 a and the other end 42 b of the spring 42 changes, so that the fitting portion 13 is The magnitude of the force F biased toward the roll medium R changes. And there is a mark 43 indicating that the magnitude of the biasing force F has become a predetermined magnitude by changing the positional relationship between the one end 42a and the other end 42b of the spring 42. Features.

  In addition, the roll medium holder device 51 of this embodiment includes a guide member 7 extending in the width direction X of the roll medium R, and is slidable in the width direction X while being guided by the guide member 7. A first holder portion 3 that holds the first portion 3 so that the first holder portion 3 can be extended. The first holder portion 3 is slidable with respect to the guide member 7 and is movable in the width direction X with respect to the base portion 4. And a spring that urges the fitting portion 13 toward the roll medium R in the width direction X, with the fitting portion 13 fitting into the core port 12 of the roll core 11 of the roll medium R and the one end 42a side contacting the fitting portion 13. 42 and a moving member 44 that contacts the other end 42b side of the spring 42 and is movable in the width direction X with respect to the base portion 4, and positions of the one end 42a and the other end 42b of the spring 42 are provided. By changing the relationship, the fitting portion 13 is moved to the roll medium R side. The magnitude of the urging force F is changed, and the magnitude of the urging force F becomes a predetermined magnitude by changing the positional relationship between the fitting portion 13 and the moving member 44 in the width direction X. In this case, the width direction outer side portion 13 a which is a part of the fitting portion 13 is aligned with the disk portion 44 a which is a part of the moving member 44.
