Description

  The present invention relates to a recording execution means for executing recording on a recording surface of a recording material, a discharge device for discharging the recording material after execution of recording from a discharge port, and recording from the discharge port via a discharge path of the recording material. The present invention relates to a recording apparatus including a manual feeding device that enables a recording material to be manually fed to an execution unit.

  2. Description of the Related Art A recording apparatus such as a so-called ink jet printer is provided with an automatic feeding apparatus for feeding a recording material such as plain paper or photographic paper to a recording execution unit. However, since a recording material such as board paper or cardboard or a disk tray cannot be bent, it is often difficult to feed the recording material to a recording execution unit with a general automatic feeding device. As an example of the prior art that can solve such a problem, a recording material such as board paper or cardboard or a disk tray is provided through a discharge path from a discharge port from which the recording material after recording is discharged. A recording apparatus including a manual feeding device that enables feeding to a recording execution unit by manual insertion is known (see, for example, Patent Document 1 or 2). According to the recording apparatus provided with such a manual feeding apparatus, recording is also performed on a recording material (hereinafter referred to as “thick paper or the like”) such as board paper or cardboard which is difficult to be fed by the automatic feeding apparatus. Can be executed. It is also possible to perform recording on the label surface of the optical disk mounted on the disk tray.

  As an example of the recording apparatus including the manual feeding device as described above, a recording apparatus including a manual feeding tray supported in a swingable manner near the discharge port on the front surface of the recording apparatus is known (for example, a patent). Reference 1). This manual feed tray is used to support the thick paper or the like from the back side when manually inserting the thick paper or the like into the recording execution means. For example, in the recording apparatus disclosed in Patent Document 1, the manual feed tray is normally held in a standing posture. During manual feeding, the user swings the manual feeding tray toward the front, so that the manual feeding tray forms a support surface for the recording material on the downstream side in the ejection direction from the ejection device. . The user places cardboard or the like on the placement surface of the manual feed tray and pushes the cardboard or the like along the placement surface toward the inside of the recording apparatus, so that the user can pass through the discharge path from the discharge port. Therefore, it is possible to easily and accurately carry out manual feeding of cardboard and the like.

  In addition, as an example of a recording apparatus including a manual feeding device, a manual feeding tray is provided so as to be slidable so as to be able to take a state of being retracted inside the recording device and a state of being advanced from a recording material discharge port. Are known (see, for example, Patent Document 2). For example, the manual feed tray of the recording apparatus disclosed in Patent Document 2 is locked by a push latch mechanism in a state of being retracted inside the recording apparatus. At the time of manual feeding, the user performs an operation of pushing the front end of the manual feeding tray that is in the retracted state inside the recording apparatus, thereby releasing the manual feeding tray from being locked by the push latch mechanism. As a result, the manual feed tray is displaced by the biasing force of the biasing means to a position where it advances from the discharge port of the recording material, and the manual feed tray causes the manual feed tray to move downstream from the discharge device in the discharge direction. The support surface of the recording material is configured. The user places cardboard or the like on the placement surface of the manual feed tray and pushes the cardboard or the like along the placement surface toward the inside of the recording apparatus, so that the user can pass through the discharge path from the discharge port. Therefore, it is possible to easily and accurately carry out manual feeding of cardboard and the like.

  The manual feeding device provided with the movable manual feeding tray as described above can easily and accurately manually feed thick paper and the like by using the manual feeding tray. There is an advantage that the manual feed tray can be stored compactly in the recording apparatus.

  However, the conventional manual feeding device provided with the movable manual feeding tray has a structure in which the manual feeding tray forms the support surface of the recording material on the downstream side in the discharging direction from the discharging device. The interval between the manual feed tray and the recording material discharge device tends to be wide. This is to reduce the interval in order to achieve a good operational feeling of the manual feed tray while avoiding the manual feed tray from interfering with the discharge device and other components in the movable range. This is because there are many cases where this is actually difficult. When manually feeding a recording material such as cardboard, the leading end of the recording material such as cardboard enters between the manual feeding tray and the discharge device and is caught, and the recording material is bent. There is a risk of damage. The catch of the recording material at the time of manual feeding is particularly likely to occur when manually feeding the recording material that is weak and easily hangs at the tip.

  The present invention has been made in view of such a situation, and the problem to be solved by some aspects of the present invention is that the problem to be solved is to manually feed the recording execution means from the discharge port through the discharge path of the recording material. In a recording apparatus equipped with a manual feeding device that enables feeding of a recording material, when the recording material is manually fed through the manual feeding device, the recording material is not bent or damaged. This is to reduce the risk of occurrence.

  According to a first aspect of the present invention, there is provided a recording execution means for executing recording on a recording surface of a recording material, a discharge device for discharging the recording material after execution of recording from a discharge port, and the recording material from the discharge port. A manual feeding device that enables manual feeding of the recording material to the recording execution means via a discharge path, wherein the manual feeding device is more than the discharging device. A manual feed tray provided so as to be displaceable so that a first position constituting a support surface of the recording material and a second position which is a predetermined storage position can be taken on the downstream side in the discharge direction; The recording material moves between the manual feed tray at the first position and the discharge device in conjunction with the displacement of the manual feed tray from the position to the first position. And an auxiliary tray that constitutes the support surface of A recording apparatus.

  In a state where the manual feed tray forms a support surface of the recording material downstream of the discharge device in the discharge direction (a state where the manual feed tray is displaced to the first position), the auxiliary feed tray and the manual feed tray are discharged. A support surface for the recording material is formed between the apparatus and the apparatus. Thus, when the recording material is manually fed, the recording material can be prevented from being caught between the manual feeding tray and the recording material discharging device. Further, the auxiliary tray advances into the recording material discharge path (the path that becomes the manual feeding path when manually feeding) in conjunction with the displacement of the manual feeding tray from the second position to the first position. In other words, in the state where the manual feeding of the recording material is not performed using the manual feeding tray (the state where the manual feeding tray is displaced to the second position), the auxiliary tray is in a position retracted from the discharge path. Therefore, the discharge of the recording material by the discharge device is not hindered by the auxiliary tray.

  As a result, according to the recording apparatus of the first aspect of the present invention, the manual feed that enables the recording material to be manually fed from the discharge port to the recording execution means via the recording material discharge path. In the recording apparatus including the feeding device, when manually feeding the recording material via the manual feeding device, it is possible to reduce the possibility that the recording material is bent or damaged. It is done.

  According to a second aspect of the present invention, in the recording apparatus according to the first aspect described above, the manual feeding device advances between the manual feeding tray at the first position and the discharge device. Urging means for urging the auxiliary tray in a direction to move the manual feeding tray against the urging force of the urging means when the manual feeding tray is in the second position. The auxiliary tray is locked at a position retracted from the discharge path, and the manual feeding tray is displaced from the second position to the first position, whereby the auxiliary tray by the manual feeding tray is displaced. Is released, and the auxiliary tray advances into the discharge path by the urging force of the urging means.

  According to such a feature, since the manual feed tray directly engages with the auxiliary tray and displaces the auxiliary tray, the recording apparatus according to the present invention can be realized at a low cost with a simple configuration. it can.

  According to a third aspect of the present invention, in the recording apparatus according to the first aspect described above, the manual feeding device is displaceable in a direction along a support surface of a recording material of the manual feeding tray. An auxiliary tray is supported by the manual feed tray, and a support portion that supports the manual feed tray so as to be displaceable with a predetermined displacement trajectory, and the support along the displacement trajectory of the manual feed tray. A first rack provided at a portion, a first pinion gear pivotally supported by the manual feed tray and meshing with the first rack, and a first pinion gear pivotally supported by the manual feed tray. A reverse gear that meshes with the manual feed tray, a second pinion gear that rotates together with the reverse gear, and a second pinion gear that is formed on the auxiliary tray and meshes with the second pinion gear. Rack, and having It is a recording apparatus wherein.

  The first rack is provided in the support portion along the displacement trajectory of the manual feed tray, and the first pinion gear meshes with the first rack. Therefore, the first pinion gear rotates in conjunction with the displacement of the manual feed tray. Then, the rotation of the first pinion gear is transmitted to the second pinion gear in the reverse direction by the reverse gear. The auxiliary tray is displaced in a direction along the support surface of the recording material of the manual feed tray in conjunction with the rotation of the second pinion gear. Therefore, the auxiliary tray is displaced in a direction opposite to the displacement direction of the manual feed tray.

  That is, when the manual feed tray is displaced in a direction in which the interval between the manual feed tray and the discharge device increases, the auxiliary tray moves in a direction to advance between the manual feed tray and the discharge device. Displace. On the other hand, when the manual feed tray is displaced in a direction in which the interval between the manual feed tray and the discharge device is narrowed, the auxiliary tray is retracted from between the manual feed tray and the discharge device. Displace. Therefore, even if there is a slight shift in the position of the manual feed tray that should originally be in the first position, the distance between the tip of the auxiliary tray (the end in the advance direction) and the discharge device is always kept below a certain level. Is possible.

  Further, since the auxiliary tray is supported by the manual feeding tray, the auxiliary tray is displaced integrally with the manual feeding tray as the manual feeding tray is displaced. Therefore, between the manual feed tray and the discharge device, a support surface that is always continuous with the support surface of the manual feed tray can be configured by the auxiliary tray regardless of the displacement position of the manual feed tray. .

  According to a fourth aspect of the present invention, in the recording apparatus according to any one of the first to third aspects described above, the auxiliary tray includes an auxiliary roller provided so as to be driven and rotated by a support surface of the recording material. The recording apparatus is characterized by comprising:

  According to such a feature, when the recording material is manually fed from the discharge port to the recording execution means through the discharge path of the recording material using the manual feeding device, the recording material is assisted. The possibility of being caught on the support surface of the tray can be reduced.

The transport driven roller 12 is pivotally supported by a roller holder 121 so as to be driven to rotate, and is urged in a direction to contact the transport drive roller 11 by a spring force of a torsion coil spring 122. The recording paper support member 13 supports the recording paper P from the back side. The distance between the head surface of the recording head 311 provided at the bottom of the carriage 31 and the recording surface of the recording paper P (the surface on which recording is performed; the same applies hereinafter) is maintained at a constant interval by the recording paper support member 13. Is done.

  The carriage 31 is provided with a recording head 311 at the bottom, and is supported by a carriage guide shaft 32 and a guide frame 33 so as to reciprocate in the main scanning direction X. Here, the main scanning direction X is a direction that intersects the sub-scanning direction Y (the conveyance direction of the recording paper P) along the recording surface of the recording paper P supported by the recording paper support member 13. The carriage guide shaft 32 is a component made of a metal shaft disposed along the main scanning direction X, and pivotally supports the bearing portion 312 of the carriage 31.

<First embodiment>
A first embodiment of an ink jet printer 1 according to the present invention will be described with reference to FIGS.
3 and 4 are perspective views of the main part of the inkjet printer 1 viewed obliquely from the front. FIG. 3 shows a state in which the manual feed tray 23 is accommodated therein, and FIG. 4 shows the manual feed tray 23. Each of the states that can be used after being advanced from the discharge port 5 is illustrated. 5 and 6 are perspective views of the main part of the ink jet printer 1 as viewed obliquely from the rear. FIG. 5 shows a state in which the manual feed tray 23 is accommodated therein, and FIG. 6 shows the manual feed tray 23. Each of the states that can be used after being advanced from the discharge port 5 is illustrated. FIG. 7 is a side view of a main part of the ink jet printer 1.

  First, the configuration of the “manual feeding device” of the first embodiment will be described. The “manual feeding device” of the first embodiment includes a manual feeding tray 23, an auxiliary tray 25, and two tray support members 26.

  The manual feed tray 23 has a support surface portion 231 that supports the recording paper P when manually feeding the recording paper P such as cardboard. Convex portions 232 are formed at both ends in the main scanning direction X of the manual feed tray 23. A rotating shaft 27 is supported on the manual feed tray 23. The rotary shaft 27 protrudes from both ends of the manual feeding tray 23 in the main scanning direction X, and pinion gears 28 are attached to both ends thereof.

  The auxiliary tray 25 has a support surface portion 251, a first arm portion 253, and a second arm portion 256. The support surface portion 251 is a surface that supports the recording paper P when manually feeding the recording paper P such as thick paper. Two auxiliary rollers 252 are pivotally supported on the support surface portion 251 so as to be driven to rotate. The first arm portion 253 extends below the support surface portion 251 in a direction crossing the support surface portion 251. The second arm portion 256 extends from the first arm portion 253 in a direction substantially along the support surface portion 251, and a convex portion 257 is formed in the vicinity of the tip. A spring locking portion 254 is formed between the first arm portion 253 and the second arm portion 256.

  The tray support members 26 as “support portions” are disposed on both outer sides in the main scanning direction X of the manual feed tray 23 and the auxiliary tray 25. The tray support member 26 includes a rack 261, a first guide hole 262, a second guide hole 263, a third guide hole 264, a spring locking portion 265, and an auxiliary tray locking portion 266. The first guide hole 262 and the second guide hole 263 support the manual feed tray 23 so as to be displaceable. The rack 261 is formed in the vicinity of the first guide hole 262 along the first guide hole 262. The third guide hole 264 supports the auxiliary tray 25 so as to be displaceable. The auxiliary tray locking portion 266 is provided in order to restrict the posture of the auxiliary tray 25 in the state in which the first arm portion 253 of the auxiliary tray 25 abuts in the movable range of the auxiliary tray 25.

  The manual feed tray 23 is configured so that the rotating shaft 27 is inserted into the first guide hole 262 of the tray support member 26 and the convex portion 232 is inserted into the second guide hole 263 of the tray support member 26. 26. That is, the manual feed tray 23 is supported by the tray support member 26 so as to be displaceable along the shapes of the first guide hole 262 and the second guide hole 263. Accordingly, the manual feed tray 23 is positioned at a position where the support surface of the recording paper P is formed by the support surface portion 231 on the downstream side in the sub-scanning direction Y from the first discharge drive roller 14 and the second discharge drive roller 15 (hereinafter, referred to as “the support surface portion 231”) It is supported so as to be displaceable so as to be able to take a “first position”) and a predetermined storage position (hereinafter referred to as “second position”).

  Further, the pinion gear 28 meshes with the rack 261 of the tray support member 26. That is, when the manual feed tray 23 is displaced along the shapes of the first guide hole 262 and the second guide hole 263 of the tray support member 26, the two pinion gears 28 and the rotary shaft 27 are integrated. Roll while rotating in the direction indicated by E. Thereby, the load when the manual feed tray 23 is displaced is reduced, and the manual feed tray 23 can be smoothly displaced.

  The auxiliary tray 25 is supported by the tray support member 26 in a state where the convex portion 257 of the first arm portion 253 is inserted into the third guide hole 264 of the tray support member 26. That is, the auxiliary tray 25 is supported by the tray support member 26 so as to be displaceable along the shape of the third guide hole 264. Further, a coil spring 255 as a “biasing means” is suspended between the spring locking portion 254 of the auxiliary tray 25 and the spring locking portion 265 of the tray support member 26. The auxiliary tray 25 is urged in the direction indicated by the symbol F by the spring force of the coil spring 255. That is, the coil spring 255 urges the auxiliary tray 25 in the direction of advancement between the manual feed tray 23 and the second discharge driving roller 15 at the first position.

  Next, the operation of the “manual feeding device” of the first embodiment will be described.

  In the state where the manual feed tray 23 is in the second position (the state illustrated in FIGS. 3, 5, and 7 (a)), after the recording is performed by the first discharge drive roller 14 and the second discharge drive roller 15. The manual feed tray 23 is retracted above the discharge path Pa of the recording paper P (the path that becomes the manual feed path when manually feeding). The state where the manual feed tray 23 is in the second position is held by a lock mechanism using a known push latch mechanism (not shown). In this state, the convex portion 232 of the manual feeding tray 23 pushes the auxiliary tray 25 upward against the spring force of the coil spring 255. As a result, the auxiliary tray 25 is locked at a position retracted upward from the discharge path Pa of the recording paper P after execution of recording (FIG. 7A).

  That is, in a state where the manual feed tray 23 is in a predetermined storage position (second position), both the manual feed tray 23 and the auxiliary tray 25 are above the discharge path Pa of the recording paper P after the recording is performed. Evacuated. Therefore, in this state, the recording paper P after execution of recording can be discharged without being obstructed by the manual feed tray 23 and the auxiliary tray 25.

  By performing a push operation for pushing the manual feed tray 23 from the state where the manual feed tray 23 is in the second position, the lock mechanism using the push latch mechanism is unlocked. The manual feed tray 23 is displaced in the direction indicated by the symbol C by the spring force of the coil spring 255 acting via the auxiliary tray 25 and moves to the first position. Accordingly, the support surface of the recording paper P is configured by the support surface portion 231 of the manual feed tray 23 on the downstream side in the sub-scanning direction Y from the first discharge drive roller 14 and the second discharge drive roller 15 (FIG. 4). FIG. 6 and FIG. 7B). In this state, the recording paper P such as thick paper is placed on the support surface portion 231 of the manual feed tray 23, and the recording paper P such as thick paper is directed along the support surface portion 231 toward the inside of the ink jet printer 1. Thus, it can be pushed into the manual feed direction YR. As a result, it is possible to easily and accurately feed the recording paper P such as thick paper manually from the discharge port 5 through the discharge path Pa.

  Further, due to the displacement of the manual feeding tray 23, the locking of the auxiliary tray 25 by the convex portion 232 of the manual feeding tray 23 is released. Accordingly, the auxiliary tray 25 is displaced in the direction indicated by the symbol D by the spring force of the coil spring 255 and advances into the discharge path Pa. That is, the support surface of the recording paper P is configured by the support surface portion 251 of the auxiliary tray 25 between the manual feed tray 23 and the second discharge driving roller 15 at the first position. As a result, when the recording paper P such as cardboard is pushed in the manual feeding direction YR and manually fed, the recording paper P is caught between the manual feeding tray 23 and the second discharge driving roller 15. This can be prevented.

  As described above, according to the present invention, when the recording paper P is manually fed through the manual feeding tray 23, the possibility that the recording paper P is bent or damaged can be reduced.

  In addition, it is preferable to provide two auxiliary rollers 252 on the support surface portion 251 of the auxiliary tray 25 so as to be driven to rotate as in this embodiment. This is not an essential component of the present invention, but by providing such an auxiliary roller 252, when the recording paper P is manually fed through the manual feeding tray 23, the recording paper P is bent. The possibility of causing damage or the like can be further reduced.

  Further, the auxiliary tray 25 in the state retracted from the discharge path Pa (FIG. 7A) is discharged when the recording paper P after recording is discharged in the sub-scanning direction Y along the discharge path Pa. It can also function as a guide member for the recording paper P to be printed. In other words, the recording execution is attempted to deviate from the original discharge path Pa due to, for example, upward warping caused by the back surface of the auxiliary tray 25 at the position retracted from the discharge path Pa (the back side of the support surface portion 251). It is also possible to guide the subsequent recording paper P to the original discharge path Pa. More specifically, for example, the retracted position of the auxiliary tray 25 may be set close to the upper side of the discharge path Pa as long as it does not interfere with the discharge path Pa. As a result, the possibility that the recording paper P deviates from the original discharge path Pa and a paper jam or the like occurs can be reduced. Further, the auxiliary roller 252 is disposed so as to be able to contact the recording paper P on both the support surface portion 251 and the back surface of the auxiliary tray 25, and the recording paper P about to deviate from the original discharge path Pa is placed on the auxiliary roller 252. May be guided to the original discharge path Pa.

The second pinion gear 43 is pivotally supported on the manual feed tray 23 (a support structure is not shown), and is coupled to the reverse gear 41 so as to be integrally rotatable by a coupling shaft 42. The slide type auxiliary tray 29 is formed with a second rack 291 that meshes with the second pinion gear 43.

  As described above, the rack 261 (first rack) is provided on the tray support member 26 along the displacement locus of the manual feed tray 23, and the pinion gear 28 (first pinion gear) is connected to the rack 261. Meshed. Therefore, the pinion gear 28 rotates (symbol G) in conjunction with the displacement (symbol C) of the manual feed tray 23. Then, the rotation of the pinion gear 28 is transmitted to the second pinion gear 43 as a reverse rotation (reference H) by the reverse rotation gear 41. The sliding auxiliary tray 29 is displaced in the direction (reference symbol K) along the support surface portion 231 of the manual feed tray 23 in conjunction with the rotation (reference symbol J) of the second pinion gear 43. Therefore, the sliding auxiliary tray 29 is displaced in a direction opposite to the displacement direction of the manual feed tray 23.

  That is, when the manual feed tray 23 is displaced in the direction in which the interval between the manual feed tray 23 and the second discharge drive roller 15 increases, the slide type auxiliary tray 29 is separated from the manual feed tray 23. It is displaced in the direction of moving forward (reference K) between the second discharge drive roller 15. On the other hand, when the manual feed tray 23 is displaced in a direction in which the interval between the manual feed tray 23 and the second discharge drive roller 15 is narrowed, the sliding auxiliary tray 29 is separated from the manual feed tray 23. It is displaced in the direction of retreating from the space between the second discharge drive roller 15 (the direction opposite to the direction indicated by the symbol K). Therefore, even if a slight deviation occurs in the position of the manual feed tray 23 that should originally be in the first position, the tip of the sliding auxiliary tray 29 (the end in the advance direction K), the second discharge driving roller 15, It is possible to always keep the interval of a certain value or less.

  Further, since the slide type auxiliary tray 29 is supported by the manual feed tray 23, the slide type auxiliary tray 29 is displaced integrally with the manual feed tray 23 as the manual feed tray 23 is displaced. Therefore, a support surface that is always continuous with the support surface portion 231 of the manual feed tray 23 is provided between the manual feed tray 23 and the second discharge drive roller 15 regardless of the displacement position of the manual feed tray 23. A sliding auxiliary tray 29 can be used.
