The above is the outline of the printer 1, and the paper cassette 1 will be described below with reference to FIGS.
00 will be described in detail.
As described above, the sheet cassette 100 includes the lower tray 50 and the upper tray 60, and is detachable from the apparatus body 3a of the feeding device 3. The lower tray 50 and the upper tray 60 both form a sheet storage unit, and reference numerals 50a and 60a denote the bottom surfaces of the trays.

The upper tray 60 is slidable with respect to the side walls 50b and 50c of the lower tray 50, and the sliding direction is the y direction (paper feeding direction). Lower tray 50
When the paper is fed from, that is, when the feeding roller 16 is brought into contact with the paper stored in the lower tray 50, the upper tray 60 is moved in the retracting direction (rightward in FIG. 2).

Next, the front inner wall in the sheet feeding direction in the lower tray 50 is configured to include a front end regulating wall 52 and a separation slope 53. The leading edge regulating wall 52 and the separation slope 53 are formed as inclined surfaces that extend obliquely upward so that the surface facing the leading edge of the sheet forms an opening angle with respect to the sheet stacking direction from the bottom surface 50a.

The leading edge regulating wall 52 and the separating slope 53 regulate the position of the leading edge of the paper when the paper is accommodated, but the surface of the separating slope 53 is formed with a high friction surface, and the leading edge of the paper is fed out. When the leading edge of the paper advances to the downstream side while sliding on the separation slope 53,
Separation from the next and subsequent sheets is performed.

In the upper tray 60, the inner wall on the front side in the sheet feeding direction is composed of two leading edge regulating walls 62. Similar to the leading edge regulating wall 52 and the separation slope 53 provided on the lower tray 60, the two leading edge regulating walls 62 form an opening angle from the bottom surface 60a with respect to the sheet stacking direction. Thus, it is formed with an inclined surface extending obliquely upward.

The two leading edge regulating walls 62 are arranged at a predetermined interval in the paper width direction (x direction), and when the upper tray 60 is moved to the back of the apparatus (left direction in FIG. 2), the two leading edge regulating walls 62 are arranged. A separating slope 53 formed on the lower tray 50 enters between the regulating walls 62.

That is, the separation slope 53 formed on the lower tray 50 functions as a regulating wall that regulates the front end position of the paper in the upper tray 60, and the sheet fed from the upper tray 60 is in sliding contact with the separation slope 53. By proceeding to the downstream side, separation from the next and subsequent sheets is performed. That is, the separation slope 53 formed on the lower tray 50 is
The lower tray 50 and the upper tray 60 are used in common.

In the sheet cassette 100 configured as described above, the lower tray 50 is supported by the cassette support surface 3b when mounted on the apparatus main body 3a of the feeding device 3 (in FIG. 3, the lower tray 50 is shown). Is omitted). Here, both ends of the upper tray 60 are supported by the side walls 50b and 50c of the lower tray 50 as described above, and when the sheet is fed from the upper tray 60, that is, the upper tray 60 is In the state of being moved to the front side, the downstream end of the feeding direction is supported by the apparatus main body 3a.

More specifically, at the downstream end of the upper tray 60 in the feeding direction, as shown in FIG.
When the supported portion 63 is attached to the apparatus main body 3a from the detached state with respect to the apparatus main body 3a as shown by the arrow direction in FIG. 3, the tray support 3c provided on the apparatus main body 3a is mounted. It is comprised so that it may be supported by. That is, the “upper tray support means” for supporting the upper tray 60 includes the side walls 50b and 50c of the lower tray 50 and the tray support 3c.
And is configured. The tray support portion 3c is configured to enter a predetermined amount into the downstream end region of the lower tray 50.

Hereinafter, the operation and effect of the tray support portion 3c will be described in comparison with FIG. In FIG. 6, reference numerals 500 and 600 denote lower trays according to the prior art,
A supported tray 6 that is an upper tray and is formed at the downstream end of the upper tray 600 in the feeding direction.
30 is supported by a support portion 54 formed on the lower tray 500.

Here, since the lower tray 500 is a component that can be attached to and detached from the feeding apparatus main body on the mounting side itself, the position of the lower tray 500 is accurate even if it is mounted on the apparatus main body. It is difficult to be determined. Therefore, as in the conventional configuration shown in FIG. 6, the upper tray 600 in which the height direction position of the downstream end in the feeding direction is defined by the lower tray 500 is likely to vary greatly in the position at the time of mounting. As a result, the force when the paper feed roller comes into contact with the paper stored in the upper tray 600 varies, and there is a possibility that poor feeding such as non-feed or double feed may occur.

In addition, since the support portion 54 is provided on a part of the separation slope 53, the upper tray 6
When the load of 00 is applied to the separation slope 53, the inclination angle of the separation slope 53 changes, and the separation performance may be deteriorated.

On the other hand, in the present invention, as described with reference to FIG. 3, the supported portion 63 formed at the downstream end portion in the feeding direction of the upper tray 60 has the tray supporting portion 3c provided in the apparatus main body 3a. Thus, the tray support portion 3 provided on the apparatus main body 3a side in this way is supported.
The upper tray 60 is reliably supported by c, and its position is determined appropriately and precisely. Therefore, it is possible to prevent the occurrence of feeding defects such as non-feeding and double feeding when feeding paper.

In particular, in the present embodiment, the tray support portion 3c is formed on a fixed member (one of the frames constituting the base of the feeding device 3) of the apparatus main body 3a. The position of the side tray 60 is determined appropriately and precisely.

In the present embodiment, the tray support portion 3c supports the downstream end of the upper tray 60 in the paper body feeding direction, so that the feeding angle of the paper fed from the upper tray 60 is appropriately maintained, Occurrence of poor feeding such as non-feeding and double feeding during paper feeding can be prevented more reliably.

Furthermore, in the present embodiment, the supported portion 63 has a guide shape whose tip extends obliquely upward so as to guide the upper tray 60 to the mounting position. Therefore, when the paper cassette 100 is mounted,
The upper tray 60 is smoothly mounted at the mounting position without being caught.

Note that the tray support 3c is provided on a frame member (not shown) provided with the swinging member 17 that supports the feeding roller 16, so that the positional relationship between the feeding roller 16 and the upper tray 60 is maintained. It is determined more precisely, and it is possible to more reliably prevent the occurrence of paper feed defects such as non-feed and double feed during paper feeding.

Further, the arrangement position of the tray support portion 3c in the direction (paper width direction: x direction) orthogonal to the paper feeding direction by the feeding roller 16 is set at or near the contact position between the feeding roller 16 and the paper. Thus, it is possible to effectively prevent or suppress the deformation of the upper tray 60 that occurs when the feeding roller 16 is pressed against the paper.

Furthermore, the tray support portion 3c may be formed of a cylindrical body, and the supported tray 63 formed on the upper tray 60 may enter the cylindrical body so that the upper tray 60 is supported. As a result, the upper tray 60 is restricted not only in the downward direction but also in the upward direction, or in addition to this, in the horizontal direction, and the position of the upper tray 60 is determined more appropriately and precisely.

4 (A) to 4 (C) are examples thereof, and a tray support portion 3c-1 shown in FIG. 4 (A) is a cylindrical body having a substantially cylindrical cross section, and is formed on the upper tray. The support portion 63-1 is formed in a protruding shape so as to be fitted into the fitting hole 3d-1 of the cylindrical body. Further, the tray support portion 3c-2, the fitting hole 3d-2, and the supported portion 63-2 shown in FIG. 4B are the tray support portion 3c-1 and the fitting hole shown in FIG. Each of 3d-1 and the supported portion 63-1 is extended in the height direction, the height direction dimension is increased, and the strength in the load support direction is improved. Figure 4 (
The tray support portion 3c-3 shown in C) has an opening at the entrance of the fitting hole 3d-3, and ensures the function of smoothly guiding the supported portion 63-1.

In addition, the downstream end of the lower tray 50 in the feeding direction may also be configured to engage with the apparatus main body 3a. FIG. 5 shows such an embodiment, and reference numeral 50 ′ shows a lower tray according to the other embodiment. A regulated portion 55 is formed at the downstream end of the lower tray 50 ′ in the feeding direction, and a regulation hole 3e into which the regulated portion 55 is fitted is formed on the apparatus body 3a side. As a result, the position of the downstream end of the lower tray 50 ′ in the feeding direction is more appropriately determined, and a good sheet feeding result can be obtained.

Further, the arrangement position of the restricted portion 55 and the restriction hole 3e in the direction orthogonal to the paper feeding direction by the feeding roller 16 (paper width direction: x direction) is the contact position between the feeding roller 16 and the paper or the vicinity thereof. By setting to, it is possible to effectively prevent or suppress the deformation of the lower tray 50 ′ that occurs when the feeding roller 16 is pressed against the paper.

Needless to say, the embodiment described above is merely an example, and the present invention is not limited thereto. For example, in the present embodiment, the feeding device 3 according to the present invention is applied to an ink jet printer as an example of a recording device.
