Description

  The present invention relates to a recording medium cassette provided with a multi-stage tray structure, and a recording apparatus represented by a facsimile, a printer, and the like provided with the recording medium cassette.

  Paper cassettes that can be attached to and detached from the apparatus main body have been widely used, and among them, as shown in Patent Document 1 and Patent Document 2, in one removable paper cassette (tray), the lower and upper stages are used. A two-stage structure having a sheet storage portion is known. 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 called a “cassette”, and a plurality of paper storage portions provided in the cassette is called a “tray”.

Each of the lower and upper trays is provided with a front inner wall (regulation surface) that regulates the position of the leading edge of the paper when the paper is stored. For example, as shown in FIG. 11 of Patent Document 2, the front inner wall is formed in an inclined shape with respect to the first paper feed tray (lower tray), and the front inner wall formed in the inclined shape is used for paper feeding. It is configured to function as a separating means in order to prevent double feeding at the time. In Patent Document 2, there is no particular mention regarding the front inner wall of the second paper feed tray (upper tray).
JP-A-2-231331 JP 2007-223758 A

  The inner wall on the front side of the lower tray has a margin in the height direction (paper stacking direction) with respect to the number of sheets that can be accommodated in order to accommodate the upper tray, so even when the maximum number of sheets is accommodated in the lower tray When the paper is stored, the paper does not easily jump out in the feeding direction.

  However, the inner wall on the front side of the upper tray has no margin in the height direction (sheet stacking direction) with respect to the number of sheets accommodated, and therefore, when the maximum number of sheets are accommodated in the upper tray, the sheets are particularly in the feeding direction. Since the paper is easily popped out and the paper setting state is disturbed, there is a tendency that double feeding tends to occur when the paper is sent out from the upper tray.

  Further, in the configuration in which the upper tray does not have the separation slope on the front inner wall and the separation slope of the lower tray is used, the front inner wall of the upper tray is slippery and the above-mentioned popping out is more likely to occur. Further, when the edge guide is abutted against the rear end of the paper, the front end of the paper easily slides up the front inner wall, which may disturb the paper setting state and easily cause double feeding.

  Accordingly, the present invention has been made in view of such a situation, and an object of the present invention is to configure a paper cassette having a multi-stage tray structure so that paper is stored in an appropriate state in the upper tray. In other words, it is to prevent double feeding when paper is sent out from the upper tray.

  In order to solve the above-described problem, a recording medium cassette according to a first aspect of the present invention includes a lower tray that stores a recording medium, and a recording medium feeding direction with respect to the lower tray. A recording medium cassette provided with a slidable upper tray for accommodating a recording medium, and the upper tray when the upper tray is at the most slidable position in the delivery direction.

  According to this aspect, when the upper tray is located away from the abutting position where the upper tray slides most in the delivery direction (that is, the use position of the upper tray), the recording medium stored in the upper tray is sent out. Since the stopper portion that functions to prevent movement in the direction is provided, even if the upper tray is difficult to ensure the dimensional margin of the front inner wall in the stacking direction of the recording medium, When the recording medium is stored, the recording medium can be stored in an appropriate state without easily popping out.

  Further, even when the edge guide is abutted against the rear end of the recording medium, the stopper portion prevents the leading end of the recording medium from easily sliding up the front inner wall of the upper tray, so that the stored recording medium can be removed. It can be positioned at an appropriate position.

  The recording medium cassette according to a second aspect of the present invention is the recording medium cassette according to the first aspect, wherein the lower side tray has a front inner wall located in the feeding direction, and the upper stage tray has a front side located in the feeding direction.

A separation slope for separating the recording medium is provided on at least a part of the front inner wall of the lower tray on the front side, and the upper tray is located at the abutting position. In some cases, the separation slope has a configuration that protrudes to the front side of the recording medium accommodated in the upper tray than the front inner wall of the upper tray. And features.

  According to this aspect, the separation slope provided in the lower tray can be used as a common separating means for the lower tray and the upper tray, which can contribute to cost reduction of the apparatus. In the configuration in which the upper tray does not have a separation slope on the inner wall on the front side, the set state of the recording medium is easily disturbed in the upper tray as described above. However, such a disturbed set state is caused by the first aspect. Can be prevented.

  The recording medium cassette according to a third aspect of the present invention is the recording medium cassette according to the second aspect, wherein the stopper portion is provided on at least a part of the front inner wall of the upper tray in a direction perpendicular to the feeding direction. When the upper tray is in the abutting position, the upper tray is located farther from the front end of the recording medium accommodated in the upper tray than the separation slope.

  According to this aspect, in the configuration in which the separation slope provided in the lower tray is used as a common separating means for the lower tray and the upper tray, the stopper provided in the upper tray is configured such that the upper tray When in the abutting position, it is located farther from the front end of the recording medium stored in the upper tray than the separation slope, so that it does not hinder the feeding of the recording medium from the upper tray, and the separation slope It does not interfere with the separation.

  In the recording medium cassette according to the fourth aspect of the present invention, in the second or third aspect, the inclination of the front inner wall of the upper tray is along the inclination of the front inner wall of the lower tray. It is characterized by that.

  According to this aspect, since the inclination of the front inner wall of the upper tray is along the inclination of the front inner wall of the lower tray, the lower tray is separated when the upper tray is positioned at the abutting position. The length of the recording medium storage portion of the upper tray formed by the slope is not significantly different between the upper layer side and the lower layer side of the upper tray, and the curved posture or the like that is unreasonable for the recording medium in the upper tray Can be prevented from being formed.

  The recording medium cassette according to the fifth aspect of the present invention is the recording medium cassette according to any one of the second to fourth aspects, wherein the stopper portion is formed along the inclination of the front inner wall of the upper tray. It is characterized by comprising.

  According to this aspect, since the stopper portion is configured by the concavo-convex shape formed along the inclination of the front side inner wall of the upper tray, the stopper portion can be configured with a simple structure and at a low cost. it can. In particular, since the uneven shape can be formed by resin molding, it can contribute to further cost reduction.

A recording medium cassette according to a sixth aspect of the present invention is characterized in that, in the fifth aspect, the uneven shape is a stepped shape having a surface parallel to the stacking direction of the recording media.
According to this aspect, since the concavo-convex shape is a stepped shape having a surface parallel to the stacking direction of the recording medium, the surface parallel to the stacking direction of the recording medium leads to the recording medium feeding direction. Can be reliably prevented.

The outline of the printer 1 has been described above, and the sheet cassette 100 will be described in detail below with reference to FIGS. 2 to 6 and FIG.
The lower tray 50 is provided with an edge guide 51 (FIG. 1) slidable in the paper feeding direction (that is, the paper length direction) on the bottom surface 50a. The edge guide 51 regulates the position of the trailing edge. It has become so. An edge guide that can slide in a direction orthogonal to the paper feeding direction (that is, the paper width direction) is also provided (not shown), and the position of the side edge is regulated by the edge guide.

  Further, on the bottom surface 50a, a high friction material 53 is disposed at a position corresponding to the contact position between the pickup roller 16 and the paper P1 (FIG. 4). The high friction material 53 allows the paper to be fed when the pickup roller 16 feeds the paper. The sheet bundle is held so that the bundle is not sent downstream.

  In the lower tray 50, the front inner wall in the paper feeding direction has a plurality of ribs arranged at appropriate intervals along the paper width direction (direction perpendicular to the paper feeding direction) as shown in FIGS. The comb-tooth-shaped portion 55 and the separating material holding portion 56 whose positions in the paper width direction coincide with the positions of the pickup roller 16 and the high friction material 53 are configured.

  The comb-like portion 55 has an inclined shape in which the surface 55a facing the front end of the sheet extends obliquely upward so as to form an opening angle with respect to the sheet stacking direction from the bottom surface 50a. After extending substantially parallel to the paper feeding direction, a step shape extending obliquely upward again is provided. Further, the separating material holding portion 56 has a surface 56 a facing the front end of the sheet formed in an inclined shape having substantially the same inclination angle as the inclined shape of the comb-like portion 55. Is not provided, and extends obliquely upward almost straight from the bottom surface 50a.

  The separation material holding portion 56 is provided with a friction separation material 54 that forms a “separation slope”, and when the paper is fed, the leading edge of the paper moves downstream while being in sliding contact with the friction separation material 54, and so on. Separation from other paper is performed.

  On the other hand, the upper tray 60 is also provided with an edge guide 61 slidable in the paper length direction and an edge guide 62 slidable in the paper width direction on the bottom surface 60 a, similarly to the lower tray 50. . A high friction material 63 is disposed at a location corresponding to the contact position between the pickup roller 16 and the paper P2.

  In the upper tray 60, the front inner wall in the paper feeding direction is formed by a first comb-like portion 65 and a second comb-like portion 66 in which a plurality of rib-like bodies are arranged at appropriate intervals along the paper width direction. It is configured.

  The first comb-tooth portion 65 and the second comb-tooth portion 66 are arranged at the abutting position where the upper tray 60 is slid most in the sheet feeding direction, and the comb-tooth portion 55 and the separating material holding portion 56 of the lower tray 50. The position in the paper width direction is set so that a state of alternately entering between the two is formed. In particular, the second comb-like portions 66 are arranged so as to be located on both sides of the separating material holding portion 56 as shown in FIG.

  The first comb-tooth portion 65 and the second comb-tooth portion 66 have a surface (indicated by reference numerals 65a and 64, respectively) facing the leading edge of the paper so that an opening angle is formed from the bottom surface 60a in the paper stacking direction. The first comb-like portion 65 is formed so as to extend further upward with a slight inclination angle in the middle thereof.

  In the state where the upper tray 60 configured as described above is positioned at the abutting position, the friction separating material 54 of the lower tray 50 has a front inner wall of the upper tray 60 as shown in FIG. When the paper is fed from the upper tray 60 so that the friction separating material 54 is fed out from the upper tray 60 by projecting to the front end side of the paper stored in the upper tray 60 from the first comb teeth 65 and the second comb teeth 66. It is used as a separation means. That is, the friction separating material 54 of the lower tray 50 is used as a common separating means for the lower tray 50 and the upper tray 60.

  Here, the first comb teeth 65 and the second comb teeth 66 of the upper tray 60 are inclined so that the comb teeth 55 and the separating material holding section 56 of the lower tray 50 are inclined. That is, the inclination angle is set to be substantially the same.

  Accordingly, when the upper tray 60 is positioned at the abutting position, the sheet storage length of the upper tray 60 formed by the friction separating material 54 of the lower tray 50 (left and right direction in FIG. 5B). However, there is no significant difference between the upper layer side and the lower layer side of the upper tray 60, and the friction separating material 54 strongly strikes the front end of the paper in the upper tray 60 to form an unreasonably curved posture or the like. It is preventing.

  Next, a stopper portion 64 is provided on the surface of the second comb-like portion 66 of the upper tray 60 that faces the front end of the paper. The stopper portion 64 functions to prevent the movement of the paper stored in the upper tray 60 in the feed-out direction when the upper tray 60 is positioned away from the abutting position. Hereinafter, the stopper portion 64 will be described in detail.

  The front inner walls (first comb teeth 65 and second comb teeth 66) of the upper tray 60 are compared to the front inner walls (comb teeth 55 and separator holding portions 56) of the lower tray 50. Thus, there is no margin in the height direction (paper stacking direction) with respect to the number of sheets stored. Therefore, if the stopper portion 64 is not provided, when the maximum number of sheets are stored in the upper tray 60, the sheets are likely to jump out in the feeding direction, thereby disturbing the sheet setting state. As a result, the upper tray 60 Compared to the tray 50, it has a property that double feeding is likely to occur.

  In addition, since no separation means is provided on the inner wall on the front side of the upper tray 60, if the stopper portion 64 is not provided, this causes the above-mentioned popping out to occur more easily than the lower tray 50. In addition, when the edge guide 51 is abutted against the rear end of the paper, the front end of the paper easily slides up the inner wall on the front side of the upper tray 60, and the paper setting position tends to vary in the upper tray 60. .

  However, as shown in FIGS. 6A and 6B, the upper tray 60 includes a stopper portion 64 that is configured by a concavo-convex shape formed along the inclination of the front inner wall of the upper tray 60. When the upper tray 60 is away from the abutting position, the upper tray 60 is located at a location that can be engaged with the leading edge of the paper stored in the upper tray 60 as shown in FIG.

  Therefore, even if a sheet is about to jump out when the sheet is stored in the upper tray 60, the leading end of the sheet engages with the uneven shape of the stopper portion 64, and the protrusion is prevented. Even when the edge guide 51 is abutted against the rear end of the paper, the stopper 64 prevents the front end of the paper from easily sliding up the front inner wall of the upper tray 60 and maintains an appropriate setting position. As described above, it is possible to appropriately store paper in the upper tray 60, and it is possible to prevent double feeding.

  When the upper tray 60 is at the abutting position where the upper tray 60 slides most in the sheet feeding direction, the stopper portion 64 is accommodated in the upper tray 60 rather than the friction separator 64 as shown in FIG. It will be located away from the leading edge of the paper. Therefore, when the paper is fed from the upper tray 60, the paper is allowed to be fed from the upper tray 60, and the paper separation by the friction separating material 54 is not hindered.

  In this embodiment, the stopper portion 64 is formed in a staircase shape having a surface parallel to the sheet stacking direction (vertical direction in this embodiment) as shown in FIG. Although it is comprised so that the movement to the front side may be prevented reliably, what kind of shape may be sufficient as long as it is an uneven | corrugated shape which can exhibit a stopper function.

  For example, an uneven shape as indicated by reference numeral 64 ′ in FIG. 6C or an uneven shape as indicated by reference numeral 64 ″ in FIG. 6D may be used. Further, a high friction material that exhibits a high coefficient of friction with the front end of the sheet may be used instead of the uneven shape. In addition, by further forming the concavo-convex shape as shown in FIGS. 6B to 6C integrally with the second comb-tooth portion 66 by resin molding, further cost reduction can be achieved.

  In addition, the second comb-like portion 66 provided with the stopper portion 64 is provided in a movable state in the upper tray 60, and the second comb-like portion 66 is placed in the upper tray when the upper tray 60 is in the abutting position. When the upper tray 60 is in a position away from the abutting position, it can be engaged with the front end of the paper stored in the upper tray 60. It can also be configured to be placed in place.

  In the present embodiment, the paper cassette 100 has a two-stage structure including the lower tray 50 and the upper tray 60. However, the present invention is not limited to this, and an upper tray is further provided above the upper tray 60. It is also possible to provide means having the same function as the stopper portion 64 in the upper tray.
