Description

  The present invention relates to a recording material conveying means for conveying a fed recording material in a predetermined conveying direction, and an opening / closing provided to open and close a conveyance outlet of the recording material conveyed by the recording material conveying means. The present invention relates to a recording apparatus including a cover.

  A recording apparatus such as a so-called ink jet printer is provided with an automatic feeding device that automatically feeds the recording materials stacked on the recording material stacking means one by one from the uppermost side to the recording execution means of the recording apparatus. It is common. As a feeding path different from the automatic feeding path by the automatic feeding apparatus, a manual feeding path for manually inserting a cardboard such as a photo board or a disk tray is provided in such a recording apparatus. Such recording devices are known. A known disk tray is a member on a thin plate for executing recording on the label surface of an optical recording disk such as a CD-R. By feeding the disc tray loaded with the optical recording disc from the manual feed path, transporting the disc tray as a recording material, and executing recording, the label surface of the optical recording disc loaded on the disc tray is applied. Recording can be executed (see, for example, Patent Document 1).

  In such a recording apparatus, a part of the manual feed path is generally configured to also serve as a recording material conveyance path. In addition, the feeding direction of the manual feed path (the direction in which the disc tray or the like is fed) is opposite to the recording material conveyance direction from the viewpoint of user convenience or the like. Generally, feeding is performed from the front side of the recording apparatus, which is the material discharge port side. For this reason, when feeding a disc tray or the like from the manual feed path, a paper discharge driven roller or the like disposed in a state where a part of the manual feed path also serves as a part of the manual feed path is advanced. In order to protect from a disc tray or the like to be sent, a means for retracting from the transport path is generally provided in advance (see, for example, Patent Document 1).

  In a recording apparatus having such a manual feed path, when a recording material is fed from the manual feed path, some special operation or attachment of an adapter or the like is required. Is common. For example, when the paper output stacker provided at the recording material discharge opening is opened while being opened from the closed state, the paper output stacker in the open state is guided to the manual feed path entrance when it is opened upward. A recording apparatus configured to form a surface is known (see, for example, Patent Document 1). Alternatively, a recording apparatus is known in which a predetermined adapter or the like is separately attached to the discharge port of the recording material to form a guide surface to the entrance of the manual feed path (see, for example, Patent Document 2). .

  However, when a recording material is fed to the manual feed path, a configuration that requires some special operation or attachment of an adapter or the like has a problem that the operation is difficult for the user to understand and is not convenient. there were. Therefore, in order to solve such problems, a dedicated opening / closing cover is provided at the feeding port of the manual feeding path, and the recording material can be fed to the manual feeding path simply by opening the opening / closing cover. A recording apparatus having the following structure is known. Special operations that are difficult for the user to understand are not necessary, and the troublesomeness of attaching an adapter separately is eliminated, improving the convenience of feeding the recording material from the manual feed path and executing the recording. Can be realized.

  However, by providing a dedicated opening / closing cover at the feed port of the manual feed path, when recording is performed on the recording material fed from the manual feed path, a predetermined transport direction (from the manual feed path) Interference between the front end of the recording material conveyed in the direction opposite to the feeding direction and the opening / closing cover becomes a problem. When a dedicated cover is provided at the feeding port, the recording material that is normally transported in the specified transport direction during recording is transported while being discharged from the discharge port, and is fully opened. It does not interfere with the opening / closing cover. However, for example, when the open / close cover is in a half-open state during recording on the recording material fed from the manual feed path, or the recording material fed from the manual feed path interferes with the open / close cover. In the case where the recording material is warped, the recording material conveyed in a predetermined conveying direction may come into contact with the opening / closing cover. Then, the tip of the recording material such as a disc tray conveyed in a predetermined conveying direction is caught by a part of the opening / closing cover, and an excessive load is applied to the recording material conveying means, or the recording material is bent. There is a risk of clogging.

  The present invention has been made in view of such a situation, and the problem is that, in a recording apparatus having a manual feed path in the feed direction opposite to the conveyance direction of the recording material, This is to reduce the possibility that the recording material being conveyed is caught by the opening / closing cover of the manual feeding path when the fed recording material is conveyed in a predetermined conveyance direction.

  In order to achieve the above object, according to a first aspect of the present invention, there is provided an automatic feeding device that automatically feeds a recording material, and a recording material conveyance unit that conveys the fed recording material in a predetermined conveyance direction. And a manual feeding path for feeding the recording material to the recording material conveying means in a feeding path different from the feeding path of the recording material by the automatic feeding device, and the manual feeding path An opening / closing cover provided to be able to open and close the entrance portion, wherein the manual feed path is a recording apparatus configured to include a part of the recording material transport path, wherein the manual feed path Is configured to feed the recording material from a conveyance direction exit side of the recording material conveyed by the recording material conveying means to a predetermined feeding position in a direction opposite to the conveyance direction, The recording material is pivotally supported and conveyed by the recording material conveying means. When the leading end of the recording material transported by the recording material transporting unit comes into contact with the opening / closing cover, the leading end of the recording material is disposed so as to open in the material transporting direction. Is guided toward the front end of the opening / closing cover in the swinging direction, and has a recording material guide portion formed so as to be guided to the outside of the opening / closing cover without being caught by the front end of the opening / closing cover. This is a recording apparatus characterized by that.

In this way, the leading end of the recording material conveyed by the recording material conveying means is guided toward the leading end of the opening / closing cover in the swinging direction, and the outside of the opening / closing cover is not caught by the leading end of the opening / closing cover in the swinging direction. To be guided to. In the case of a recording material having low rigidity, the recording material is guided while being guided by the recording material guide portion so that the tip is warped upward. In the case of a highly rigid recording material such as a disc tray or a photo board, the tip of the disc tray or the like is ejected while swinging in the opening direction by pushing the opening / closing cover while sliding on the opening / closing cover, At that time, the recording material guide portion prevents the front end of the disc tray or the like from being caught on the opening / closing cover.
Therefore, when the recording material fed from the manual feeding path is transported in a predetermined transport direction, the possibility that the recording material being transported is caught by the opening / closing cover of the manual feeding path can be reduced. The effect is obtained.

In this way, even when the opened cover is closed, it is ensured that the opened cover is in a closed state by a certain operation similar to that when opening the cover (pushing a predetermined position of the cover from the outside to the inside). Since it can be returned, it is possible to prevent the opening / closing cover from being slightly opened.

According to a sixth aspect of the present invention, in the fourth aspect or the fifth aspect described above, the open / close cover has a shape in which the other end side enters the inside of the boundary portion with the main body cover in the closed state. The recording apparatus is characterized by that.
Even if the opening / closing cover is locked, it is possible to more reliably prevent the user from forcibly opening the opening / closing cover through the gap between the closed opening / closing cover and the main body cover.

A seventh aspect of the present invention is the recording apparatus according to the sixth aspect, wherein the recording material guide portion is formed inside the vicinity of the other end side of the opening / closing cover. .
Since the opening / closing cover has a shape in which the other end side enters the inside of the boundary with the main body cover in the closed state, the opening / closing cover is conveyed by the recording material conveying means to the other end side of the opening / closing cover. The leading edge of the recording material is easily caught. Thus, by forming the recording material guide portion described above inside the vicinity of the other end side of the opening / closing cover, the possibility of the recording material being caught on the other end side of the opened opening / closing cover is reduced. Can be made.

The tray is retracted from the transport path in conjunction with the opening operation of the tray cover 4, and is advanced into the transport path in conjunction with the closing operation of the disc tray cover 4. More specifically, the paper discharge frame 49 (FIG. 4) pivotally supporting the plurality of first paper discharge driven rollers 472 and the second paper discharge driven rollers 482 is interlocked with the opening operation of the disc tray cover 4. Thus, it moves as described above. Accordingly, the transport driven roller 42, the first paper discharge driven roller 472, the second paper discharge driven roller 482, and the like are protected from the manually inserted disc tray TR.

  When manually inserting the disc tray TR, the conveyance driven roller 42, the paper detector (not shown), etc. are also temporarily retracted from the conveyance path automatically according to the opening operation of the disc tray cover 4. Is preferred. In conjunction with the opening / closing operation of the disc tray cover 4, the carriage guide shaft 61 is moved up and down by a known PG adjusting device (not shown) that operates using the conveying motor 51 (FIG. 3) or the like as a driving force source. Thus, the distance between the head surface of the recording head 63 mounted on the carriage 62 and the platen 46 is automatically adjusted.

Next, the opening / closing mechanism of the disc tray cover 4 will be described with reference to FIGS.
The disc tray cover 4 is supported so as to be capable of opening and closing and swinging about a shaft 4a. The disc tray guide member 81 is supported so as to be swingable about a shaft 812 as a swing shaft. In the disc tray guide member 81, the right convex portion 814 of the disc tray guide member 81 is engaged with the right guide groove 403 of the disc tray cover 4, and the left convex portion 815 is similarly engaged with the left guide groove 404 of the disc tray cover 4. If not shown in FIGS. 6 to 9 (see FIG. 11), the disk tray cover 4 swings in conjunction with opening and closing. In the closed state, the disc tray cover 4 is kept closed with the claw portion 407 engaged with the cover opening / closing switch 7 (FIG. 6). The cover open / close switch 7 has a so-called alternate contact structure, and when the operation of pushing and releasing the tip is repeated, the contact circuit configuration (ON / OFF) and the tip position (advance / retreat) are alternately switched.
The front end 406 of the disc tray cover 4 has a shape that enters the inside of the boundary with the main body cover 1 as shown in FIG. 6 (FIG. 6). As a result, the user forcibly opens the disc tray cover 4 from the gap between the closed disc tray cover 4 and the main body cover 1 even though the disc tray cover 4 is locked. It can prevent more reliably.

  When a predetermined position of the disc tray cover 4 in the closed state (a portion corresponding to the arrangement of the cover opening / closing switch 7) is pushed in from the outside to the inside (reference A), the tip position of the cover opening / closing switch 7 is opened (reference numeral). The disc tray cover 4 is moved in the opening direction (the swinging direction indicated by C) while the engagement between the cover opening / closing switch 7 and the claw portion 407 is released. It swings to the “movement position” (FIG. 7). The “openable swinging position” means that the disc tray cover 4 is directly swung in the opening direction (swing direction indicated by C) between the front end 406 of the disc tray cover 4 and the main body cover 1. This is the swing position of the disc tray cover 4 where a gap that allows opening operation is generated. The right convex portion 814 of the disc tray guide member 81 is moved in the direction indicated by the symbol D along the right guide groove 403 of the disc tray cover 4. As a result, the disk tray guide member 81 swings in the swing direction indicated by the symbol E in conjunction with the swing of the disc tray cover 4 in the opening direction (the swing direction indicated by the symbol C). (FIG. 7).

  When the disc tray cover 4 is operated by the user to open in the opening direction (swing direction indicated by the symbol C) (for example, an operation to open the front end 406 of the disc tray cover 4 with a finger), Further, it swings in the opening direction (swing direction indicated by symbol C) (FIG. 8). The right convex portion 814 of the disc tray guide member 81 is further moved in the direction indicated by the symbol D along the right guide groove 403 of the disc tray cover 4. As a result, the disk tray guide member 81 is further swung in the swing direction indicated by the symbol E in conjunction with the swing of the disc tray cover 4 in the opening direction (the swing direction indicated by the symbol C). Go (Fig. 8). The disc tray cover 4 has a “boundary rocking position” (the rocking position shown in FIG. 8) as a boundary, and on the side closer to the “boundary rocking position” than the “boundary rocking position”, The oscillating position shown in FIG. 9 is biased to the “open oscillating position” (the oscillating position shown in FIG. 9).

Then, the disc tray TR can be manually inserted via the disc tray guide member 81 while the disc tray cover 4 is swung to the “open swing position” (FIG. 9) where the disc tray cover 4 is fully open. (FIG. 9). Further, the swinging position of the disc tray guide member 81 is regulated by a disc tray cover lock device to be described later via the convex portion 813.
The engagement state between the left convex portion 815 (FIG. 11) of the disc tray guide member 81 and the left guide groove 404 (FIG. 11) of the disc tray cover 4 is the same as the right convex portion 814 of the disc tray guide member 81 described above. Since it is similar to the engagement state of the disc tray cover 4 with the right guide groove 403 (FIGS. 6 to 9), the description thereof is omitted.

  Next, the “manual feed path” for manually inserting the disc tray TR with the disc tray cover 4 opened will be further described.

FIG. 12 is a perspective view of the ink jet recording apparatus 100 showing an enlarged portion where the disc tray cover 4 is opened.
In a state (FIGS. 9 and 12) in which the disc tray cover 4 is opened to the “open swing position” (FIG. 9, FIG. 12), a direction (indicated by reference sign F) that opposes the recording material conveyance direction from the guide portion 811 of the disc tray guide member 81 The disc tray TR can be inserted by hand. The guide portion 811 of the disc tray guide member 81 is provided with a right guide portion 818 and a left guide portion 819 that guide manual insertion of the disc tray TR. The disc tray TR that is manually inserted by the right guide portion 818 and the left guide portion 819 is in a state where the top and bottom and both side ends are positioned, so that the disc tray TR is moved in the manual insertion direction (direction indicated by F). The disc tray TR can be easily manually inserted to the accurate feeding position through the accurate feeding path only by performing an operation of pushing it to a predetermined insertion position. Inside the disc tray cover 4 are a first reinforcing rib 408, a second reinforcing rib 409, a third reinforcing rib 4c, and a fourth reinforcing rib 4d as “recording material guide portions” as shown in the drawing. It is formed near the portion 406 (details will be described later). Further, a concave portion 4b is formed at the front end portion 406 of the disc tray cover 4 according to the shape of the front cover 8 as shown in the figure.

13 to 15 are side cross-sectional views showing the main parts of the ink jet recording apparatus 100 in a state in which the disc tray TR is conveyed in the sub-scanning direction Y by the rotation of the conveyance drive roller 41.
FIG. 13 shows a state in which the front end of the disc tray TR has abutted against the inside of the disc tray cover 4.
In the state where the disc tray cover 4 is opened to the “open swing position”, the disc tray guide member 81 has a guide portion 811 as shown in the drawing along the conveyance path (from the outer peripheral surface of the conveyance drive roller 41 via the platen 45 to the first one. Oscillating to a swing position that has advanced into the paper discharge path so that it is substantially collinear with the paper discharge drive roller 471 and the second paper discharge drive roller 481 (the path through which the “recording material” is conveyed). It has become. The disc tray TR that has been manually inserted to a predetermined insertion position starts recording on the label surface of an optical recording disc (not shown) mounted on the disc tray TR, similar to when recording on the recording paper P. Then, it is transported in the sub-scanning direction Y by the rotation of the transport driving roller 41.
Note that the first paper discharge driven roller 472 and the second paper discharge driven roller 482 (not shown) are a first paper discharge drive roller 471 and a second paper discharge drive roller 481 by a release means (not shown). It is in a state where it is retracted to a position away from. Accordingly, when recording is performed on the manually inserted disc tray TR, the disc tray TR is sandwiched between the transport drive roller 41 and the transport driven roller 42, and the recording is started only by the rotation of the transport drive roller 41. It is conveyed until the end of recording.

  When the disc tray TR is being conveyed in the sub-scanning direction Y by the rotation of the conveyance drive roller 41, if the disc tray cover 4 is in a half-open state for some reason, the leading end of the disc tray TR is moved to the disc tray as shown in the figure. It will bump into the inside of the cover 4 (FIG. 13). When the disc tray TR is further conveyed in the sub-scanning direction Y in this state, the disc tray cover 4 is pushed by the tip of the disc tray TR and is swung in the opening direction (direction indicated by G). Go.

FIG. 14 shows a state where the front end of the disc tray TR is in contact with the vicinity of the front end portion 406 of the disc tray cover 4.
However, as described above, the front end portion 406 of the disc tray cover 4 has a shape that enters the inside of the boundary with the main body cover 1 as shown in the figure (the explanation of the opening / closing mechanism of the disc tray cover 4 is described below). reference). For this reason, the disc tray cover 4 swings in the opening direction (the direction indicated by G) while the disc tray cover 4 is pushed against the tip of the disc tray TR in a state where the tip of the disc tray TR abuts the inside of the disc tray cover 4. Then, the tip of the disc tray TR may be caught by the tip portion 406 of the disc tray cover 4. In such a state, when the transport driving roller 41 further rotates in the transport direction, an excessive load is applied to the portion where the transport tray 41 is sandwiched between the transport driving roller 41 and the transport driven roller 42. Become. As a result, the outer peripheral surface (high frictional resistance coating surface) of the transport driving roller 41 may be damaged, and the transport accuracy of the transport driving roller 41 may be significantly reduced.

  In order to prevent this, the ink jet recording apparatus 100 according to the present invention includes the first reinforcing rib 408, the second reinforcing rib 409, the third reinforcing rib 4c, and the fourth reinforcing rib 4d. Is formed in the vicinity of the front end 406 of the disc tray cover 4 as shown in FIG. The first reinforcing rib 408, the second reinforcing rib 409, the third reinforcing rib 4c, and the fourth reinforcing rib 4d are in contact with the front end of the disc tray TR conveyed in the sub-scanning direction Y substantially evenly. They have substantially the same shape and are arranged in a well-balanced manner with a certain distance as shown (FIG. 12).

  The first to fourth reinforcing ribs (reference numerals 408, 409, 4 c, 4 d) are provided when the front end in the sub-scanning direction Y of the disk tray TR conveyed by the conveyance drive roller 41 contacts the disk tray cover 4. The tip of the disc tray TR is guided toward the tip of the disc tray cover 4 in the swinging direction, and is guided to the outside of the disc tray cover 4 without being caught by the tip of the disc tray cover 4 in the swinging direction. . As a result, the leading end of the disc tray TR is guided by the first to fourth reinforcing ribs (reference numerals 408, 409, 4c, and 4d) as shown in the figure without being caught by the leading end 406 of the disc tray cover 4, While continuing to push the disc tray cover 4 in the opening direction, the disc tray cover 4 advances in the sub-scanning direction Y while swinging in the opening direction.

FIG. 15 shows a state in which the disc tray cover 4 is pushed to the tip of the disc tray TR and is swung to the “open swing position”.
The front end of the disc tray TR advances from the front end portion 406 of the disc tray cover 4 to the downstream side in the sub-scanning direction Y, and the disc tray cover 4 that has been in the half-open state is swung open to a substantially “open swing position”. It becomes a state.
The disk tray TR has been described above as an example, but the same applies to a thick and highly rigid recording material such as a photo board. Further, in the case of a cardboard or the like having low rigidity, the front end thereof is guided by the first to fourth reinforcing ribs (reference numerals 408, 409, 4c, and 4d), and the disk tray cover 4 is not swung. In some cases, the toner is transported to the outside of the four front end portions 406. In any case, since the “recording material” is prevented from being caught by the front end portion 406 of the disc tray cover 4, the outer peripheral surface (high frictional resistance coating surface) of the transport driving roller 41 is damaged and the transport driving roller is damaged. It is possible to prevent the conveyance accuracy due to 41 from being significantly reduced. Further, by configuring the “recording material guide portion” with the reinforcing ribs, it is possible to obtain a reinforcing effect against the deformation of the disc tray cover 4.

  In this way, when the disc tray TR manually inserted from the “manual feed path” is transported in a predetermined transport direction, there is a possibility that the disc tray TR being transported may be caught by the opening / closing cover of the manual feed path. Can be reduced.

  The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the invention described in the claims, and these are also included in the scope of the present invention. Needless to say.
