  The transport driving roller 11 is formed by applying a high friction coating on the outer peripheral surface of the metal shaft, and rotates by receiving the rotational driving force of a transport motor (not shown). The transport driven roller 12 is pivotally supported so as to be driven to rotate in a state of being biased in a direction in contact with the transport drive roller 11. The recording paper support member 13 is a member that supports the recording paper P in contact with the back surface of the recording paper P as a “recording material” in a region where ink is ejected from the recording head 17. The discharge driving roller 14 is rotated by receiving the rotational driving force of the conveying motor. The discharge driven roller 15 is pivotally supported so as to be driven to rotate and is urged in a direction in which the discharge driven roller 15 contacts the discharge drive roller 14.

  The carriage 16 is supported by a carriage guide shaft 18 and a carriage support frame 19 so as to be able to reciprocate in the main scanning direction X. 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 18 and the carriage support frame 19 are disposed along the main scanning direction X. The carriage 16 is connected to an endless belt (not shown) that rotates in both directions by the rotational driving force of a carriage motor (not shown). The endless belt is hung on a drive pulley and a driven pulley (not shown) of the carriage motor, and is disposed substantially parallel to the carriage guide shaft 18 and the carriage support frame 19. That is, the carriage 16 can be reciprocated in the main scanning direction X by bidirectionally rotating the endless belt with the driving force of the carriage motor.

  The recording head 17 is mounted on the carriage 16 so that the head surface faces the recording surface of the recording paper P supported by the recording paper support member 13. The head surface of the recording head 17 is provided with a number of ejection nozzles (not shown) for ejecting ink onto the recording surface of the recording paper P to form dots. Ink is supplied to the recording head 17 from an ink tank (not shown) provided in the main body of the inkjet printer 1 via an ink tube (not shown).

  The ink jet printer 1 includes an automatic feeding device 20 that automatically feeds the recording paper P before recording. The automatic feeding device 20 includes a roller support member 21, a feeding roller 22, a first driving roller 23, a first driven roller 24, an intermediate driven roller 25, a second driving roller 26, a second driven roller 27, and a feeding cassette unit. 30 is included.

  The feeding cassette unit 30 as the “recording material container” is provided so as to be insertable / removable in the direction indicated by the symbol B. Details of the configuration of the feeding cassette unit 30 will be described later.

  The roller support member 21 is a member that supports the feeding roller 22, and is supported so as to be swingable in a direction indicated by a symbol A with the shaft portion 211 as a swing shaft. More specifically, the roller support member 21 can feed the feed cassette unit 30 so that it can take an entry position where the roller support member 21 can come into contact with the recording paper P and a retreat position that does not interfere with insertion / extraction of the feed cassette unit 30. The feed roller 22 is supported so as to be displaceable. The feeding roller 22 is rotatably supported by the roller support member 21. The roller support member 21 swings in the direction indicated by the symbol A by rotating a swing motor (not shown).

  The feeding roller 22 is rotated by receiving the rotational driving force of an automatic feeding motor (not shown). The first driving roller 23 and the second driving roller 26 are rollers for feeding the recording paper P fed out by the feeding roller 22 to the recording execution area, and the rotation is performed through a rotation transmission mechanism (not shown). The rotation driving force of the automatic feeding motor is transmitted and rotated. The first driven roller 24, the intermediate driven roller 25, and the second driven roller 27 are pivotally supported so as to be driven to rotate.

The recording is executed on the recording surface by repeating the main scanning operation for forming dots on the recording surface by being ejected and the sub-scanning operation for transporting in the sub-scanning direction Y by a predetermined transport amount. A series of these recording controls are executed by a control device (not shown) including a known microcomputer control circuit.

FIG. 2 is a perspective view of the feeding cassette unit 30 of the first embodiment. FIG. 3 is a side sectional view of the feeding cassette unit 30 of the first embodiment. FIG. 4 is an enlarged side sectional view of a part of the automatic feeding device 20 of the first embodiment.
The feeding cassette unit 30 has a multistage structure including a first feeding cassette 31 and a second feeding cassette 32.

  The first feeding cassette 31 as the “first accommodating portion” is a box-shaped member having an open top surface as shown in the drawing, and a plurality of recording papers P are stacked on the inner bottom surface and accommodated therein. Is done. For example, the first feeding cassette 31 stores recording paper P having a relatively large size such as A4 size. The first feeding cassette 31 includes a separation portion 312, two slide groove portions 312 and two slide support portions 313.

  The separation unit 311 is a known separation mechanism, and locks the leading end of another recording sheet P to be fed in a state where it is overlapped with the recording sheet P to be fed by the rotation of the feeding roller 22. The double feeding of the recording paper P is prevented. The two slide groove portions 312 as “bearing portions” are long grooves formed on the inner side surfaces of the side wall portions (wall portions at both ends in the main scanning direction X). The two slide support portions 313 are protrusions formed on the inner surface of the side wall portion. The slide groove portion 312 and the slide support portion 313 constitute a “slide support mechanism” that supports the second feed cassette 32 with respect to the first feed cassette 31 so as to be slidable in the direction indicated by the symbol D. Further, the slide groove portion 312 constitutes a “rotation support mechanism” that supports the second feeding cassette 32 so as to be rotatable in the direction indicated by the symbol C with respect to the first feeding cassette 31.

  The second feeding cassette 32 as the “second storage portion” is a member including a box-shaped portion whose upper surface is open as shown in the figure, and a plurality of recording papers P are contained inside the box-shaped portion. Stacked and stored on the bottom. For example, the second feeding cassette 32 accommodates recording paper P having a relatively small size such as an L size or a business card size. The second feeding cassette 32 includes a rotation shaft portion 321, a bottom surface portion 322, a front side wall portion 323, a left side wall portion 324, a right side wall portion 325, a rear side wall portion 326, and two protrusions 327.

  Rotating shaft portions 321 as “shaft portions” are provided on both sides of the front side of the second feeding cassette 32 (downstream side in the sub-scanning direction Y). The slide groove 312 is fitted. A bottom surface portion 322 that comes into surface contact with the recording paper P to be accommodated, and a front side wall portion 323, a left side wall portion 324, a right side wall portion 325, and a rear side wall portion 326 that are formed so as to rise from the bottom surface portion 322. Constitutes the box-shaped part in which a plurality of recording papers P are stacked and accommodated on the inner bottom surface. The ridge portion 327 is formed on the outer surface of the left side wall portion 324 and the right side wall portion 325, and is in contact with the two slide support portions 313 of the first feeding cassette 31.

  The feeding cassette unit 30 having such a configuration can rotate the second feeding cassette 32 in the direction indicated by the symbol C with the rotation shaft portion 321 as the rotation center (rotation support mechanism). As a result, the recording paper P can be accommodated in the first feeding cassette 31 without removing the second feeding cassette 32 from the first feeding cassette 31, so that the operation of the higher feeding cassette unit 30 can be performed. Sex can be secured.

  The second feeding cassette 32 is supported by the slide groove portion 312 of the first feeding cassette 31 via the rotation shaft portion 321, and the protrusion 327 is provided on the slide support portion 313 of the first feeding cassette 31. Supported through. Thereby, the feeding cassette unit 30 can slide the second feeding cassette 32 in the direction indicated by the symbol D (slide support mechanism). Then, the user slides the second feeding cassette 32 to change the position of the second feeding cassette 32 so that the recording paper P stored in the first feeding cassette 31 is fed, or the second feeding cassette 32 is fed. Whether to feed the recording paper P stored in the feeding cassette 32 can be selectively switched.

  More specifically, when the second feeding cassette 32 is slid in the pull-out direction D1 (FIG. 4A), the first feeding cassette 31 is displaced by displacing the feeding roller 22 to the entry position. In this state, the feeding roller 22 comes into contact with the recording paper P stored therein. Therefore, the recording paper P stored in the first feeding cassette 31 can be fed by rotating the feeding roller 22 from this state. On the other hand, in a state in which the second feeding cassette 32 is slid in the pushing-in direction D2 (FIG. 4B), the feeding roller 22 is moved to the entry position and is accommodated in the second feeding cassette 32. The feeding roller 22 comes into contact with the recording paper P. Therefore, the recording paper P accommodated in the second feeding cassette 32 can be fed by rotating the feeding roller 22 from this state.

  The second feeding cassette 32 includes two rotating shaft portions 321, a bottom surface portion 322, a front side wall portion 323, a left side wall portion 324, a right side wall portion 325, a rear side wall portion 326, and two protrusions 327 formed integrally. Is a single part formed integrally. Accordingly, the second feeding cassette 32 has at least a portion on which the recording paper P is placed (a portion constituted by a bottom surface portion 322, a front side wall portion 323, a left side wall portion 324, a right side wall portion 325, and a rear side wall portion 326). It is relatively easy to ensure a certain level of rigidity. Therefore, according to the present invention, the strength of the second feeding cassette 32 against bending deformation can be improved in the feeding cassette unit 30 having a multistage structure. In particular, as described above, the size of the recording paper P stacked inside the second feeding cassette 32 is often smaller than that of the first feeding cassette 31. However, even if the size of the recording paper P is small, for example, the L-size size and the business card size are often relatively thick. Accordingly, in the second feeding cassette 32, a relatively large force tends to act when the recording paper P is fed, so that the strength against the bending deformation of the second feeding cassette 32 is improved as in the present invention. It becomes very effective. Further, the second feeding cassette 32 is integrally formed with a rotating shaft portion 321 on which a support load is concentrated by integral molding. This is not an essential component of the present invention, but by adopting such a configuration, the strength of the second feeding cassette 32 against bending deformation can be further improved. Furthermore, according to the present invention, in the multi-stage feeding cassette unit 30, the number of parts can be further reduced as compared with the conventional one in which the portion on which the recording paper P is placed is composed of a plurality of parts. Therefore, manufacturing and assembly costs can be reduced.

  In the second feeding cassette 32 according to the present invention, all of the bottom surface part 322, the front side wall part 323, the left side wall part 324, the right side wall part 325 and the rear side wall part 326 are continuous as in the first embodiment. In order to further improve the strength of the portion on which the recording paper P is placed, it is preferable that the box shape is integrally formed. However, the present invention is not necessarily limited to such a mode. For example, the front side wall 323, the left side wall 324, the right side wall 325, or the rear side wall 326 may not be provided and a simpler configuration may be used.
