Description

The present invention relates to a recording apparatus provided with a recording head for recording on a recording medium, represented by a FAX, a printer, or the like .

An example of the recording apparatus and the liquid ejecting apparatus is an ink jet printer. The ink jet printer has a feeding unit capable of setting a plurality of sheets as a recording medium, feeds one sheet at a time from the feeding unit, conveys the sheet to the ink jet recording head, and performs ink jet recording. In general, the recording is performed by the head and then discharged by the discharging means. In recent years, ink jet printers that can perform ink jet recording directly on the label surface of an optical disk typified by CD-R (Compact Disc Rewritable) and DVD (Digital Versatile Disc) have been on the market.
Such an ink jet printer has a dedicated straight path (conveyance path) because the optical disk does not have flexibility. Then, an optical disk is set on a tray having a plate shape, and the inkjet recording is performed by conveying the linear path.

  By the way, the recording medium fed from the feeding means passes through the first path having the curved path portion in order to pass through the feeding roller. And since the said tray cannot go through a curved path | route, it is comprised so that it may pass through a linear 2nd path | route. Therefore, in the vicinity of the intersection position of the first route and the second route, a first posture for forming the first route and a second posture for forming the second route, The guide member which can change is provided (for example, refer patent document 1).

JP 2002-128317 A

  Incidentally, detection means for detecting the passage of the paper is provided in the vicinity of the guide member. The detection means includes a detection lever that swings in contact with the paper and a sensor that detects the state of the detection lever (for example, a sensor including a light emitting unit and a light receiving unit), and the detection lever Is provided so that its tip enters a hole formed in the guide member. When the sheet passes, the detection lever is pushed up and swings, and the sensor detects the swinging operation, thereby detecting the passage of the leading end of the sheet.

  Here, the guide member is held in the first posture by the urging force of the urging unit. However, when the paper fed from the feeding unit has high rigidity, such as a dedicated paper having a coat layer, for example. When the leading edge of the paper comes into contact with the guide member, the guide member may be pushed down by a certain amount.

8 and 9 are views for explaining this state, FIG. 8 is a side view of the guide member, and FIG. 9 is a perspective view of the guide member. In the figure, symbol P indicates a sheet, arrow indicates a traveling direction of the sheet P, symbol 22 indicates a guide member, symbol 23 indicates a conveyance driving roller, symbol 26 indicates a platen, and symbol 41 indicates a detection lever.
The guide member 22 is swingable about the transport drive roller 23 as a swing shaft, and is biased upward (to take the first posture) by the pressing spring 43. Therefore, when a sheet P such as plain paper is fed obliquely from above, the leading end of the sheet P abuts on the guide member 22 and is guided to the transport driving roller 23. Further, when a tray (not shown) on which an optical disk is set is inserted almost horizontally from the downstream side of the transport driving roller 23, the guide member 22 is pushed downward by the tray as shown in FIG. Take the second position.

  On the other hand, above the guide member 22, a detection lever 41 having a substantially "<" shape when viewed from the side is provided so as to be able to swing around a swing shaft 41a. In the detection lever 41, the lower side from the swing shaft 41a is a contact end that contacts the paper P, and the upper side from the swing shaft 41a is a detection end 41c that enters an optical sensor (not shown). As shown in FIG. 9, a hole 22b is formed in the guide member 22, and the lower end of the contact end 41b is provided so as to slightly enter the hole 22b. Therefore, when the paper P is guided by the guide member 22 and proceeds to the transport drive roller 23, the detection lever 41 is swung by pushing the contact end 41b upward, and the upper detection end 41c is moved from the optical sensor. Then, the passage of the leading edge of the paper P is detected.

  By the way, when the front end of the paper P abuts against the guide member 22, if the paper P is plain paper or the like having low rigidity, the state of the guide member 22 does not change as shown in FIG. P contacts the guide member 22 and proceeds downstream. However, when the paper P is a special paper having high rigidity, the guide member 22 is pushed by the front end of the paper P and slightly swings downward as shown in FIG. Then, the position of the part where the paper P and the contact end 41b of the detection lever 41 contact changes, and the detection timing (the swing start timing of the detection lever 41) is shifted by the distance a. As a result, variations (errors) occur in detection of passage of the paper P, and correct paper feed control cannot be executed. In particular, when executing the scooping-out discharge-type skew removal, the leading edge of the paper P may not be discharged upstream from the transport driving roller 23, and the skew may not be removed.

  On the other hand, in order to solve such a problem, it can be considered that the urging force of the pressing spring 43 is made strong, but in this case, the force required for the tray inserted from the downstream side to push down the guide member 22. Therefore, when recording is performed with an optical disk or the like set on a tray (not shown), the guide member 22 is strongly pressed against the tray, resulting in a demerit that the transport load increases.

  Therefore, the present invention has been made in view of such a problem, and the problem is that a guide member provided in the vicinity of an intersection position between a first path having a curved path portion and a linear second path is provided. In other words, the optimum state is always obtained when each route is used, and the shift in the sheet detection timing due to the change in the posture of the guide member is eliminated.

  In order to solve the above-described problems, a first aspect of the present invention includes a recording head for recording on a recording medium, and a conveyance unit that is provided upstream of the recording head and conveys the recording medium to the recording head. A feeding unit provided upstream of the conveying unit and provided with a feeding roller for feeding the set recording medium to the conveying unit; and provided downstream of the recording head, And a first path including a curved path through which the flexible recording medium fed from the feeding means passes, and a discharging means for discharging the recorded recording medium to the outside of the apparatus. And a linear second path through which a plate-shaped tray formed so as to be able to set a recording medium having no flexibility passes, and on the downstream side of the discharge means Can be opened and closed in front of the device. By opening the door, the tray is supported and the second path is formed, and the storage state is changed so that the storage state is closed so that the opening state is substantially vertical. A first posture for forming the first path and a second position for forming the second path in the vicinity of the intersection position between the tray guide, the first path, and the second path. A guide member that guides the recording medium, a detection lever that is provided so that a tip thereof enters a hole provided in the guide member, and a state of the detection lever A recording medium detecting means including a detector, and the guide member is in conjunction with the opening / closing operation of the tray guide, and takes the first posture when the tray guide is in the retracted state. Keep in the first position Is characterized in that the tray guide is constructed as to be held in the second attitude with taking the second posture and the said open state.

  According to the above aspect, the guide member provided in the vicinity of the intersection position of the first path and the second path is interlocked with the opening / closing operation of the tray guide that supports the guide member, and the tray guide is in the housed state. Then, the first posture is taken and held in the first posture, and when the tray guide is in the open state, the second posture is taken and held in the second posture. Therefore, when the recording medium applies an external force to the guide member, the posture of the guide member does not change and the state of the path does not change, and the detection lever detects the passage of the recording medium. There is no deviation in detection timing. Further, the guide member takes an appropriate posture according to the type of the recording medium to be recorded, that is, according to the state of the tray guide, and the posture is maintained, so that the recording medium is always appropriately conveyed. It becomes possible. As described above, the guide member provided in the vicinity of the intersection position between the first path having the curved path portion and the linear second path can always be in an optimum state when each path is used. It becomes.

  According to a second aspect of the present invention, in the first aspect, the guide member is provided so as to be capable of swinging with a transport driving roller constituting the transport means as a swing shaft, and the guide member is provided in the second mode. In conjunction with the opening and closing operation of the tray guide, the biasing means for applying a biasing force in the direction of taking the posture, the support means for supporting the guide member against the biasing force of the biasing means, The support means is configured to change the posture of the guide member in conjunction with the opening / closing operation of the tray guide by link means for switching between a state in which the tray guide is supported and a state in which the tray guide is not supported. To do.

  According to the above aspect, the guide member biases the guide member in the direction of taking the second posture, and the support that supports the guide member against the biasing force of the biasing means. Since the posture is maintained by the means, even when the recording medium passing through the first path has high rigidity, that is, even when the recording medium applies a large external force to the guide member, the guide member The posture is not changed by the support means, whereby the first posture can be reliably held, and an appropriate feeding operation can be executed.

  An ink jet printer (hereinafter referred to as “printer”) 1 as an example of a “recording apparatus” and a “liquid ejecting apparatus” according to an embodiment of the present invention will be described below with reference to FIGS. Here, FIG. 1 is an external perspective view of the printer 1, FIGS. 2 and 3 are schematic side sectional views of the printer 1, and FIGS. 4 and 5 are a cam mechanism and a link mechanism that link the tray guide 18 and the guide member 22. FIG. 6 and FIG. 7 are views showing another embodiment of a link mechanism for linking the tray guide 18 and the guide member 22. In the following, the left direction (the printer rear side) in FIGS. 2 to 7 is referred to as the “upstream side” of the paper conveyance (feed) path, and the right direction (the printer front side) is referred to as the “downstream side”. To do.

In the following, first, a schematic configuration of the printer 1 will be described. In FIG. 1, the printer 1 includes a feeding device 50 capable of setting a plurality of recording papers (hereinafter referred to as “paper P”) as an example of “recording medium” and “ejection medium” at an inclined position, In the front of the apparatus, as shown in FIG. 1, the sheet P is stacked by being opened to the front side of the apparatus, and the storage state is closed so as to be in a substantially vertical standing state from the opened state (not shown). ) Is provided in a lower case (not shown) that forms the bottom of the apparatus. The stacker 13 includes a stacker body 14 and a sub stacker 15 and is rotatable about a rotation shaft (not shown) of the stacker body 14. Then, the stacking surface on which the sheets P are stacked is formed by pulling out the sub stacker 15 from the stacker main body 14 in a state of being rotated and opened toward the front side of the printer.
The upper portion of the printer 1 is covered with a housing 11, and an openable and closable cover (not shown) for exchanging ink cartridges and the like is provided at the upper center of the housing 11. 50, the stacker 13, the housing 11, and the cover constitute an external appearance of the printer 1.

  Next, the conveyance path (feeding path) of the paper P will be described in detail with reference to FIG. In FIG. 2, the feeding device 50 includes a hopper 51, a feeding roller 53, a retard roller 61, and guide rollers 57 and 58, and a conveying unit that conveys the paper P to the inkjet recording head 29. The set sheets P are fed one by one from the uppermost one toward the transport driving roller 23 and the transport driven roller 24 constituting the above.

  More specifically, the hopper 51 is formed of a plate-like body, and is configured to be swingable around an upper swing shaft 51a. The hopper 51 is supported in an inclined posture by swinging with a cam means and a biasing means (not shown). It is possible to change between a state in which the sheet P is pressed against the feeding roller 53 and a state in which the sheet P is separated from the feeding roller 53. The feeding roller 53 has a substantially D shape when viewed from the side, is integrally formed with the feeding roller shaft 54 and a resin material, and a rubber material is wound around the outer periphery. The feeding roller 53 feeds the paper P pressed by the arc portion to the downstream side, while the paper P is fed and is not transported by the transport driving roller 23 and the transport driven roller 24 so as not to generate a transport load. As shown in the figure, the flat portion is controlled to face the paper P.

A retard roller 61 as a separating unit that separates the uppermost sheet P to be fed from the next and subsequent sheets P is provided so as to be in press contact with the arc portion of the feeding roller 53 and has a predetermined rotational resistance. Is provided. Here, in the case where only one sheet P is fed without occurrence of double feeding of the sheet P, the retard roller 61 is driven to rotate in the clockwise direction in FIG. When there are a plurality of P between the feeding roller 53 and the retard roller 61, the rotation is stopped due to the low coefficient of friction between the sheets. Accordingly, the next and subsequent sheets P to be double-fed by the uppermost sheet P to be fed do not advance downstream from the feeding roller 53, and thus double feeding is prevented.
The guide rollers 57 and 58 are pivotally supported so as to be freely rotatable, and the paper P does not come into contact with the feeding roller 53 and cause a transport load while the paper P is transported by the transport drive roller 23 and the transport driven roller 24 on the downstream side. Have a role.

  Subsequently, the sheet P fed by the feeding device 50 is guided by a guide member 22 having a shape long in the main scanning direction, and is driven to rotate by a motor (not shown). It reaches the conveyance driven roller 24 which is in pressure contact with the roller 23 and rotates. Here, between the feeding roller 53 and the conveyance driving roller 23, a “recording medium detecting unit” is provided that includes a detection lever 41 and an optical sensor (not shown) that detects the state of the detection lever 41. A paper detector is provided. The detection lever 41 is provided so as to be able to oscillate about the oscillating shaft 41a, and the lower part from the oscillating shaft 41a is configured to be able to contact the paper P to be fed. The lower end of the detection lever 41 is provided so as to slightly enter a hole 22b (see FIG. 9) formed in the guide member 22. When the paper P passes, the detection lever 41 swings so as to be pushed upward. The upper end of the detection lever 41 is disengaged from the optical sensor so that the passage of the leading edge of the paper P can be detected.

  Subsequently, the transport driven roller 24 provided on the downstream side of the detection lever 41 is pivotally supported by the holder 21, and the holder 21 is a spring (not shown) on a main frame (not shown) constituting the base of the printer 1. Is attached through. The paper P that has reached the transport driving roller 23 is transported to the downstream side at a predetermined pitch by the rotation of the transport driving roller 23.

  An ink jet recording head (hereinafter referred to as “recording head”) 29 and a platen 26 are disposed on the downstream side of the transport driving roller 23 so as to face the recording head. The recording head 29 is provided at the bottom of the carriage 30, and the carriage 30 is driven to reciprocate in the main scanning direction by a drive motor (not shown) while being guided by a carriage guide shaft 37 extending in the main scanning direction. In addition, the carriage 30 is mounted with an independent ink cartridge (not shown) for each of a plurality of colors, and supplies ink to the recording head 29.

  Subsequently, on the downstream side of the recording head 29, an auxiliary roller 34, a discharge driving roller 31 and a discharge driven roller 32 constituting a discharge unit are provided. The discharge driving roller 31 is rotationally driven by a motor (not shown), the discharge driven roller 32 is driven to rotate in contact with the discharge driving roller 31, and the paper P on which recording has been performed by these rollers is discharged toward the stacker 13. A plurality of discharge driven rollers 32 are provided on a frame 35 formed of a metal plate that is long in the main scanning direction. When transporting a tray T (described later) on which an optical disk as an example of a recording medium is transported, as shown in the figure. The frame 35 is displaced upward so that the discharge driven roller 32 is separated from the discharge drive roller 31. The auxiliary roller 34 is driven to rotate while being in contact with the paper P from above, and prevents the paper P from being lifted to maintain a constant distance between the paper P and the recording head 29.

  The above is the outline of the paper conveyance path. The printer 1 is configured to be capable of ink jet recording directly on the label surface of an optical disk represented by a compact disk in addition to the paper P as a recording medium. The optical disc D is transported through the paper transport path in a state of being set on a tray T having a plate shape. The tray T is configured separately from the printer 1 and is inserted while being supported by the tray guide 18 from the front side of the printer 1.

  The tray guide 18 is provided to be openable and closable (rotatable) downstream of the discharge drive roller 31 and the discharge driven roller 32, and supports the tray T by opening toward the front of the apparatus as shown in FIGS. As shown in FIG. 2, it is provided so as to be changeable by rotating between an open state and a stowed state closed so as to become a substantially vertical standing state from the open state. In conjunction with the opening / closing operation of the tray guide 18, the above-described frame 35 is configured to be displaced vertically. When the tray guide 18 is opened, the frame 35 is displaced upward as shown in FIG. When the discharge driven roller 32 is separated from the discharge drive roller 31 and the tray guide 18 is stored, the frame 35 is displaced downward and the discharge driven roller 32 contacts the discharge drive roller 31. Therefore, the discharge driven roller 32, which is a toothed roller having teeth on the outer periphery, can prevent the occurrence of a problem that the data on the optical disk is destroyed.

  Next, the guide member 22 will be described in detail. The printer 1 includes a first path (see FIG. 2) including a curved path through which the sheet P as a flexible recording medium fed from the feeding device 50 passes as described above. Two recording medium conveyances with a linear second path (see FIG. 3) through which a tray T having a plate shape is formed so that an optical disk as a recording medium having no flexibility can be set. Has a road. The guide member 22 has a first posture for forming the first route and a second posture for forming the second route in the vicinity of the intersection of the first route and the second route. And are provided to be changeable.

  More specifically, as shown in FIG. 4, the guide member 22 is provided so as to be able to swing clockwise and counterclockwise when the transport path is viewed from the side with the transport drive roller 23 as a swing shaft. It is biased downward by a biasing means (for example, a torsion spring). On the other hand, a cam member 69 as a “support means” in which a pinion 69a and a cam 69b are integrally formed is disposed below the guide member 22 so as to be rotatable about a shaft 69c. In the state shown in FIG. 4 (the state in which the guide member 22 forms the first path), the guide member 22 is lifted upward against the urging force of the urging means.

  Next, the cam gear 69a meshes with a rack 68 provided so as to be slidable in a substantially horizontal direction, and the rack 68 has a projection 68a formed in a link rod 67 having a generally U shape when viewed from the front. By being loosely inserted into the hole 67a, the link rod 67 is engaged. The link rod 67 is engaged with the tray guide 18 by inserting a protrusion 18b provided on the tray guide 18 into the hole 67b.

  4, the cam 69b pushes the guide member 22 upward to form a first path through which the flexible paper P passes (as shown in the figure). First posture). However, when the tray guide 18 is pivoted about the pivot shaft 18a to be in the open state, the link rod 67 slides the rack 68 as shown in FIG. 5, thereby rotating the cam member 69 and the cam 69b. The guide member 22 is brought into a non-engagement state, and the guide member 22 swings so as to be displaced downward by the urging force of the urging means as shown in FIG. 5, whereby the second path through which the tray T passes is formed. Formed (second posture of the guide member 22).

  That is, when the guide member 22 is interlocked with the opening / closing operation of the tray guide 18 and the tray guide 18 is in the retracted state, the guide member 22 assumes the first posture and is held in the first posture, and the tray guide 18 is in the open state. The second posture is taken and the second posture is held. Accordingly, the guide member 22 takes an appropriate posture according to the type of medium on which recording is performed, that is, according to the state of the tray guide 18 and is held in that posture. When the rigidity of P is high, the guide member 22 is not pushed down by the rigidity of the paper P, and the state of the path does not change, and the paper P can always be conveyed appropriately. That is, the guide member 22 provided in the vicinity of the intersection position of the first path having the curved path portion and the linear second path can always be in an optimum state when each path is used. Since the positional relationship between the guide member 22 and the detection lever 41 does not change, there is no deviation in the detection timing of passage of the paper P by the detection lever 41. Further, in order to prevent such a problem, it is not necessary to strengthen the urging force of the urging means (the pressing spring 43 in FIG. 8) that holds the guide member 22 in the first posture. Can be transported smoothly without load.

  In addition, in the prior art described with reference to FIGS. 8 and 9, since the guide member 22 is urged to take the first posture by the pressing spring 43, the second path is The guide member 22 applies a pressing force from below to above on the transported tray T. Therefore, this may become a transport load and a good recording result may not be obtained. However, according to the present invention, since the guide member 22 automatically takes an appropriate posture in accordance with the posture of the tray guide 18, no transfer load is applied to the tray T, and a good recording result can be obtained.

  The tray guide 18 and the guide member 22 can be linked in the embodiment as shown in FIGS. In FIG. 6, the guide member 22 is urged downward by urging means (for example, a tension spring) (not shown) as in the above-described embodiment. On the other hand, a link rod 75 as a “support means” having a substantially L shape is provided below the guide member 22, and the link rod 75 is engaged with the tray guide 18 via a rack 73. That is, the tray guide 18 is provided with a pinion 71 having the same swing center as the swing center of the tray guide 18 and is rotated according to the swing operation of the tray guide 18. Then, the pinion 71 meshes with the rack 73, and when the tray guide 18 swings, the rack 73 erected substantially vertically slides in the vertical direction.

  On the other hand, the link rod 75 extending substantially horizontally is formed with a support portion 75b extending substantially vertically, and the support portion 75b supports the guide member 22 from below so as to hold the guide member 22 in the first posture. A projection 75c is formed near the center of the link rod 75, and is loosely inserted into a long hole 74 formed in a frame (not shown). When the tray guide 18 rotates, as shown in FIG. 7, the link rod 75 swings around the projection 75c as a fulcrum, the support portion 75b is displaced downward, and the support state of the guide member 22 by the support portion 75b is changed. The guide member 22 is released and swings so as to be displaced downward under the biasing force of the biasing means. As described above, as in the above-described embodiment, the guide member 22 takes the first posture when the tray guide 18 is in the retracted state in conjunction with the opening / closing operation of the tray guide 18, and the tray guide 18 is in the open state. Since it is configured to take the second posture, the guide member 22 is held in an appropriate state according to the route to be used, that is, according to the state of the tray guide 18. There is no deviation in the passage detection timing, and the paper P can be appropriately conveyed.
