The second sheet feeding cassette is configured to be slidable and rotatable with respect to the second sheet feeding cassette. However, the second sheet feeding cassette is configured to include a fixed part and a movable part. It has become.

  Further, when the movable portion is rotated, the movable portion is displaced from the horizontal posture to the upright posture side, so that there is a possibility that the paper stored in the second paper feed cassette may fall off.

  Accordingly, the present invention has been made in view of such a situation, and an object thereof is to obtain a multi-stage paper cassette that can be reduced in cost by a simpler structure. Another object of the present invention is to obtain a paper cassette that can prevent the paper from dropping when the upper cassette is rotated.

  In addition, there are various names such as “cassette” and “tray” as a paper storage unit for storing paper in the recording apparatus. In this specification, an entire unit unit that can be attached to and detached from the apparatus main body is referred to as “ The cassette is referred to as a “cassette”, and a plurality of paper storage portions constituting the cassette are referred to as “tray”.

  In order to solve the above problems, the recording medium cassette according to the first aspect of the present invention is slidable with respect to the lower tray on the lower tray for storing the recording medium and the upper portion of the lower tray. And an upper tray that accommodates a recording medium and that is rotatably provided and has a rotating shaft that is directly supported by the lower tray.

  According to this aspect, since the rotation axis of the upper tray is directly supported by the lower tray, it is not necessary to connect the upper tray via, for example, a fixed portion that does not rotate with respect to the lower tray. Further, it is possible to reduce the cost of the multi-stage type recording medium cassette with an even simpler structure.

  According to a second aspect of the present invention, in the first aspect, the upper tray is provided with the rotation shaft and a predetermined interval in the sliding direction of the upper tray with respect to the rotation shaft.

■■■ 2. Details of the paper cassette ■■■■■■■■■■■■■■■■■■■■■■■■■
The outline of the printer 1 has been described above. Hereinafter, the lower tray 50 and the upper tray 60 constituting the paper cassette 100 will be described in more detail with reference to FIG.
The lower tray 50 is provided with an edge guide 52 slidable in the sheet feeding direction on the bottom surface 50 a, and the position of the trailing edge is regulated by the edge guide 52. In this specification, the paper feeding direction (from the paper cassette 100) is the left direction in FIGS. 2 and 3, and the paper length direction and the sliding direction of the upper tray 60 are the left and right in FIGS. Direction. The paper width direction is the front and back direction of the paper surface of FIGS.

  The lower tray 50 is also provided with an edge guide 51 that is slidable in the sheet width direction, and the edge guide 51 regulates the position of the side edge on one side of the sheet. In FIG. 5, an edge guide 51 that restricts one side edge of the paper appears, but an edge guide that restricts the other side edge is also provided (not shown). In the present embodiment, the two edge guides 51 that regulate the side edges of the paper can be displaced synchronously so that they are located symmetrically about the center position in the paper width direction. That is, the printer 1 according to the present embodiment uses the center position in the sheet width direction as the feeding reference position (the same applies to the upper tray 60).

  On the bottom surface 50a of the lower tray 50, a high friction material 53 is disposed in the vicinity of a position corresponding to the contact position between the pickup roller 10 and the paper P1, and the high friction material 53 causes the paper to be fed out by the pickup roller 10. The sheet bundle is held so that the sheet bundle is sometimes not sent downstream.

  A stopper 50d that restricts the position of the leading edge of the sheet is provided on the leading end side of the sheet in the lower tray 50 (the left side in FIG. 5), and when the sheet is set on the lower tray 50 by the stopper 50d, The tray 50 is configured not to jump out. It should be noted that the stopper 50d does not enter the back of the apparatus from the separation slope 14 and contact the leading edge of the sheet to be sent out when the sheet cassette 100 is mounted on the apparatus main body 2 as described above. That is, the stopper 50d does not hinder the paper feeding during the paper feeding.

  On the other hand, as shown in FIG. 6, the upper tray 60 also has an edge guide 62 slidable in the paper length direction and an edge guide 61A slidable in the paper width direction on the bottom surface 60a, similarly to the lower tray 50. 61B and a stopper 64. Further, a high friction material 63 is disposed in the vicinity of a place corresponding to the contact position between the pickup roller 10 and the paper P2.

Next, the movable structure of the upper tray 60 will be described. The upper tray 60 is slidable and rotatable with respect to the lower tray 50.
More specifically, guide rails 50h are respectively formed inside the side walls 50b and 50c of the lower tray 50 (FIGS. 4 and 5 show the guide rail 50h shown on the one side wall 50b. )

Further, a guide hole 50 e extending in the sliding direction of the upper tray 60 is formed at the tip of the side walls 50 b and 50 c of the lower tray 50.
On the other hand, a boss 60c as a “rotating shaft” and a protrusion 60e as a “supported portion” are formed on both sides of the front end portion of the upper tray 60. The boss 60c is provided on the leading end side in the sheet feeding direction in the upper tray 60, and the protrusion 60e is provided at a predetermined interval in the sliding direction of the upper tray 60 with respect to the boss 60e.

  The boss 60c enters the guide hole 50e of the lower tray 50, and the protrusion 60e is supported by the guide rail 50h of the lower tray 50, so that the upper tray 60 is moved to the lower tray 50. It will be in the state supported with respect to slidable.

  In other words, the upper tray 60 is supported by the lower tray 50 at a total of four locations including the two bosses 60c and the two protrusions 60e, and these four locations slide in contact with the lower tray 50. A flange portion 60d having a diameter larger than that of the boss 60c is formed at the tip of the boss 60c so that it can be locked to the edge of the guide hole 50e.

  A rack portion 60b is formed on the upper surface of one end of the upper tray 60 along the sliding direction of the upper tray 60, and a rack and pinion gear (not shown) meshes with the rack portion 60b. A pinion mechanism is configured, and the pinion gear is rotated by the power of a motor (not shown), so that the upper tray 60 is slid between a feedable position (butting position: FIG. 3) and a retracted position (FIG. 2). It is like.

  Incidentally, in a state where the upper tray 60 is supported by the lower tray 50, a stopper 50f as a “restraining means” is provided above the protrusion 60e formed on the upper tray 60, and the upper tray 60 is provided. Is located in a position other than the feedable position (butting position: FIG. 3), the stopper 50f prevents the protrusion 60e, that is, the rear side of the upper tray 60 from being displaced in the direction intersecting the sliding direction (specifically, upward). , Will be restrained.

  When the upper tray 60 is in the feedable position (butting position: FIG. 3), the unconstrained portion 50g is positioned above the protrusion 60e as shown in FIGS. 7 and 8, that is, the stopper 50f. The restraint of the projection 60e due to is released. Accordingly, in this state, the upper tray 60 has the front boss 60c as a rotation axis, as shown by a change from FIG. 9 to FIG. 10, and as indicated by the phantom line and reference numeral 60 ′ in FIG. It can be rotated in the direction of taking a standing posture.

  Thereby, there exist the following effects. That is, the stopper 64 is provided on the leading end side in the sheet feeding direction in the upper tray 60 (FIGS. 4 and 6). The stopper 64 functions to restrict the leading edge of the paper so that the paper does not fall off when the paper is set in the upper tray 60, but when the upper tray 60 is in a place other than the butting position in the slidable range. When the upper tray 60 is rotated, the stopper 64 may come into contact with the recording surface of the paper stored in the lower tray 50 and damage the recording surface.

  However, as described above, the upper tray 60 can be rotated only when it is in the abutting position. Therefore, even if the upper tray 60 is rotated in this state, the stopper 64 does not move as shown in FIG. As a result, the stopper 64 is disengaged from the leading end side of the paper P1 accommodated in the tray 50, whereby the stopper 64 can be prevented from damaging the recording surface of the paper P1 accommodated in the lower tray 50.

  When the upper tray 60 is rotated as shown in FIG. 10 (opened state), the sheet storage area of the lower tray 50 is opened, and in this state, the sheet can be easily placed in the lower tray 50. Can be set. This series of operations (operation of rotating the upper tray 60 and setting paper in the lower tray 50) is performed in a state where the paper cassette 100 is detached from the apparatus main body 2.

  By the way, when the upper tray 60 is in the first posture (FIG. 4, FIG. 7, FIG. 9, FIG. 10 (solid line)) having the smallest angle with at least the lower tray 50 in the rotatable range, It can slide with respect to the side tray 50.

  However, even when the paper cassette 100 is removed from the apparatus main body 2 and the upper tray 60 is rotated from the first posture to take a posture other than the first posture, that is, the protrusion 60e of the upper tray 60. Can be slid by the boss 60c displacing the guide hole 50e even when the upper tray 50 is above the stopper 50f of the lower tray 50.

  However, such a state is an abnormal state, that is, the upper tray 60 is in a half-open state, and if the paper cassette 100 is mounted in the apparatus main body 2 in this state (not noticed by the user), the apparatus malfunctions. There is a risk of inviting.

  Therefore, it is also preferable to configure the guide hole 50e 'as shown in FIGS. 12 (A) and 12 (B). The guide hole 50e ′ has a recess 50j on the tip side, and when the upper tray 60 is rotated when the upper tray 60 is in the abutting position, the guide hole 50e ′ changes from FIG. 12 (A) to FIG. 12 (B). As shown in the change, the boss 60c falls into the recess 50j.

  Thereby, when the upper tray 60 takes a posture other than the first posture, the boss 60c can be restricted from being displaced in the guide hole 50e '. That is, the recess 50j constitutes a restricting means for restricting the sliding operation of the upper tray 60. Further, since the boss 60c falls into the recess 50j, the boss 60c becomes difficult to move in the guide hole 50e ′ when the upper tray 60 rotates, and thus the upper tray 60 can be stably rotated. it can.

  When the recess 50j is formed in the guide hole for guiding the boss 60c, the boss 60c does not fall into the recess 50j in the state shown in FIG. 12A, that is, in the first posture of the upper tray 60 (first In order to maintain the posture), the upper tray 60 is further provided with a projection 60e supported by the lower tray 50 (for example, a position slightly rearward from the boss 60c), and a plurality of projections 60e in FIG. It is preferable that the state can be maintained.

  Note that the guide hole may be configured as indicated by reference numeral 50 ″ in FIG. 13. A protrusion 50k is provided in the guide hole 50e '' shown in FIG. When the upper tray 60 is positioned at the butting position, the boss 60c moves over the protrusion 50k and moves to the butting position in FIG. As a result, when the upper tray 60 rotates, the boss 60c is difficult to move in the guide hole 50e '', and thus the upper tray 60 can be stably rotated.

  As is clear from the configuration described above, according to the paper cassette 100 of the present invention, the upper tray 60 is directly supported by the lower tray 60 with the boss 60c serving as a pivot shaft when rotating. Therefore, there is no need to connect the upper tray 60 via, for example, a fixed portion that does not rotate with respect to the lower tray 50, and the multi-stage paper cassette can be manufactured at a lower cost with a simpler structure. Can be achieved.

  Next, the stopper provided on the leading end side in the sheet feeding direction in the upper tray 60 will be described. As shown in FIGS. 4 and 6, the upper tray 60 is provided with stoppers 64 (two in this embodiment) on the leading end side in the sheet feeding direction. The stopper 64 includes a first stopper portion 60f and a second stopper portion 60g.

  The first stopper portion 60f is opposed to the front end of the paper, and functions to regulate the paper so that the paper does not pop out when the paper is set in the lower tray 50. The second stopper 60g is formed so as to extend from the first stopper 60f to a position reaching the top surface of the front end of the sheet. When the upper tray 60 is rotated in a direction to take a standing posture, the second stopper 60g Prevents the stored paper from falling off.

  That is, as shown in the change from FIG. 9 to FIG. 10, when the upper tray 60 is rotated in order to set the paper in the lower tray 50 with the paper stored in the upper tray 60, Since the sheets stored in the upper tray 60 are also in the standing posture, there is a possibility of dropping from the upper tray 60.

  However, as described above, the stopper 64 includes not only the first stopper portion 60f facing the front end of the sheet but also the second stopper 60g that reaches the top surface of the front end of the sheet. Therefore, as shown in FIG. The two stoppers 60g can securely hold the leading edge of the sheet and prevent the sheet from dropping from the upper tray 60.
