  In the conventional recording medium cassette, the recording medium is accommodated in the accommodating portion, and after moving each edge guide so as to contact the end (edge) of the recording medium (set state), the accommodating portion is closed with the cover case. . Here, if it is necessary to readjust the displacement of the edge guide, for example, when the edge guide is strongly (or weakly) against the edge of the recording medium, the cover case must be removed again to make the edge guide operable. did not become.

  It is an object of the present invention to provide a recording medium cassette that can easily adjust the degree of abutment of an edge guide against the edge of a recording medium accommodated in a base case.

  The recording medium cassette of the present invention is configured to be detachable from a recording apparatus that performs recording on a recording medium, and is provided so as to cover a base case having a storage portion for storing the recording medium, and a storage portion of the base case, A cover case that opens and closes the housing portion; an edge guide that is provided slidably with respect to the cover case and guides the recording medium by contacting at least one end of the recording medium housed in the housing portion when the housing portion is closed; The edge guide has an operation element exposed on the surface of the cover case opposite to the base case.

According to this configuration, after the recording medium is accommodated in the base case and the accommodating portion is closed by the cover case, the edge guide is abutted against the end (edge) of the recording medium using the operation element facing the outside of the cover case. Can do. That is, the sliding of the edge guide can be operated while the storage portion that stores the recording medium is closed by the cover case. Thereby, since the edge guide is strongly (or weakly) abutted against the edge of the recording medium, the edge guide can be easily displaced without removing the cover case again when the displacement adjustment of the edge guide is necessary.
In addition, you may displace an edge guide before obstruction | occlusion of an accommodating part with a cover case. Preferably, the edge guide is roughly aligned according to the size of the recording medium before closing, and the edge guide is abutted against the edge of the recording medium using the operation element after closing.

  In this case, the cover case has a surface opposite to the base case that functions as a holding unit for the recording medium that has been sent out of the storage state and recorded, and the edge guide is provided on the storage unit side. A supply-side guide that guides the stored recording medium, a discharge-side guide that is provided on the holding portion side, has an operation element, and guides the recording medium held by the holding portion, and is formed through the cover case. It is preferable that the connecting portion connects the supply side guide and the discharge side guide through the through hole, and is slidable along the through hole.

According to this configuration, since the supply-side guide and the discharge-side guide are provided on the front and back of the cover case, not only the recording medium in the storage unit but also the recording medium held (stocked) in the holding unit Can also guide the edges. Thereby, it is not necessary to provide a structure for sliding the edge guide separately on the supply side and the discharge side, and the structure can be simplified and the cost can be reduced.
Further, since the supply side guide and the discharge side guide are connected by the connecting portion, by displacing one of them, the other can also be displaced. Thereby, since the displacement adjustment of the supply side guide and the discharge side guide can be performed at a time, a quick and easy operation is possible.

  In this case, the edge guide is preferably provided so as to be slidable in a direction orthogonal to the conveyance direction of the recording medium.

  According to this configuration, the recording medium is set in the base case in a state of being arranged in the width direction. As a result, the recording medium is normally conveyed without shifting in the width direction, and normal recording is performed.

  In this case, it is preferable to further include a second edge guide that is slidable in the recording medium conveyance direction with respect to the base case.

According to this configuration, the recording medium is set in the base case in a state of being arranged in the length direction. In particular, when a plurality of recording media are set, it is possible to prevent conveyance failure that may occur due to unevenness of the downstream end in the conveyance direction.
Further, when a sliding structure for two edge guides is provided in one case, the structural strength of the case is lowered. However, according to the above configuration, since the second edge guide is provided not in the cover case provided with the edge guide but in the base case, it is possible to prevent the structural strength of the base case and the cover case from being lowered. it can.

  In this case, the cover case is preferably attached to the base case so as to be rotatable about one end as a rotation axis.

  According to this configuration, the cover case can largely open the accommodating portion by rotating about the rotation axis. Thereby, the recording medium can be easily accommodated in the accommodating portion.

  In this case, the cover case is attached to the base case so as to be rotatable about one end extending in a direction orthogonal to the recording medium conveyance direction, and the edge guide is detached from the cover case and conveys the recording medium. It is preferable to extend in the direction and rotate integrally with the cover case by an edge rotation shaft coaxial with the rotation shaft.

  According to this configuration, the portion of the edge guide that is removed from the cover case does not rotate, and the portion of the edge guide that is provided in the cover case rotates with the cover case about the edge rotation axis. As a result, the storage portion can be largely opened, and the edge guide at the portion where the cover case is removed serves as a guide when the recording medium is stored. Further, since the edge guide extends in the transport direction, it can come into contact with the edge of the recording medium for a long time in the transport direction, and the function as an edge guide can be reliably exhibited.

  In this case, the base case has a base main body and a slide base that is slidably engaged with the base main body, and the cover case is a slide that is slidably engaged with the cover main body and the cover main body. It is preferable that each of the slide base and the slide cover slides in the conveyance direction of the recording medium.

  According to this configuration, the slide base and the slide cover can be slid in accordance with the recording medium to be set, so that an appropriately sized storage portion can be formed. Thereby, it can set appropriately irrespective of the length of a recording medium.

  In this case, it is preferable that a scale for indicating the size of the recording medium is provided on the surface of the cover case opposite to the base case.

  According to this configuration, the edge guide can be displaced according to the accommodated recording medium before the accommodating portion is closed by the cover case. Also, by checking the scale, it is possible to know the size of the stored recording medium after the storage portion is closed by the cover case. A scale may be further provided on the base case (accommodating portion) side.

An edge guide 58 provided so as to be slidable, and a length guide 63 provided so as to be slidable in the Y-axis direction with respect to the upper slide tray 57. .

  A paper front end support wall 54 a that supports the front end of the stored paper P is formed at the lower end of the main body tray 54. The paper P accommodated in the state where the recording medium cassette 5 is mounted is supported in a state where the front end thereof is in contact with the paper front end support wall 54a.

  As shown in FIGS. 4 to 7, the upper outer cover 55 rotates around a pair of left and right rotation fulcrums 55 a provided at a substantially central portion in the vertical direction of the main body tray 54. By opening the upper outer cover 55, the paper storage space S appears and the paper P can be stored. Further, the outer surface of the upper outer cover 55 (the surface facing the inner side of the apparatus when attached) functions as a holding surface 61 for holding (accumulating) the recorded paper P.

  As shown in FIGS. 2 and 3, the upper inner cover 56 slides with respect to the upper outer cover 55, and the upper slide tray 57 slides with respect to the main body tray 54. Accordingly, the paper storage space S can be expanded and contracted. When the upper inner cover 56 is extended, the outer surface of the upper inner cover 56 extends so as to continue from the outer surface of the upper outer cover 55, and the holding surface 61 is extended in the Z-axis direction. The “base case” in the claims refers to the main body tray 54 and the upper slide tray 57, and the “cover case” refers to the upper outer cover 55 and the upper inner cover 56.

  The movable tray 59 is provided on the lower side of the main body tray 54 and rotates around a pair of left and right swinging fulcrums 59a (see FIG. 4) so that the leading end of the stored paper P is brought into pressure contact with the feeding roller 41. It swings between a state (see FIG. 3) and a separated state (see FIG. 2) (so-called hopper). Further, as shown in FIG. 4, the movable tray 59 has a plurality of contact openings at appropriate intervals along the X-axis direction so that the feeding roller 41 can be pressed into a position corresponding to the front end of the paper P. 59b is formed.

  As shown in FIGS. 2 to 5, the edge guide 58 includes a supply-side guide 64 that guides the paper P stored in the paper storage space S, and a discharge-side guide 65 that guides the paper P held on the holding surface 61. And a connecting portion 66 that connects the supply side guide 64 and the discharge side guide 65 through a long hole 55 b formed through the upper outer cover 55.

  The edge guide 58 is slidably provided along the elongated hole 55b at the connecting portion 66, and comes into contact with the edge of the paper P from the right side in FIGS. Guide the movement in the axial direction. Thereby, the paper P is set in the paper storage space S in a state of being arranged in the width direction, and is normally conveyed without being shifted in the width direction.

  As shown in FIGS. 2 to 5, the supply-side guide 64 includes an upper guide 71 located in the sheet storage space S (inside the upper outer cover 55), a lower guide 72 located inside the movable tray 59, and A guide rotation fulcrum 73 that rotatably connects the lower end portion of the upper guide 71 and the upper end portion of the lower guide 72 is provided. That is, the lower guide 72 is formed so as to be detached from the upper outer cover 55 and extend in the transport direction of the paper P. Therefore, the lower guide 72 can come into contact with the left and right edges of the paper P for a long time in the transport direction (Z-axis direction). For this reason, the function as the edge guide 58 can be exhibited reliably.

  As shown in FIGS. 6 and 7, the guide rotation fulcrum 73 is provided coaxially with the pair of left and right rotation fulcrums 55a. Therefore, the upper guide 71 rotates together with the upper outer cover 55. As a result, the paper storage space S can be greatly opened, and the edge guide 58 at a portion where the upper outer cover 55 is removed serves as a guide when the paper P is stored. Further, the pair of left and right swinging fulcrums 59a described above are provided with a position slightly below and behind the pivot fulcrum 55a and the guide pivot fulcrum 73 (see FIGS. 2 and 3). Thereby, the lower guide 72 can be rotated together with the movable tray 59.

  Next, the discharge-side guide 65 has a guide bar 74 provided on the holding surface 61 side and extending upward from the connecting portion 66, and a plate-like portion 75 connected to the upper end portion of the guide bar 74. doing. The plate-like portion 75 is provided so as to face the paper P from one end in the X-axis direction (the right side in FIGS. 4 and 6) with respect to the discharged paper P. Further, the guide bar 74 and the plate-like portion 75 serve as operating elements for the user to perform the sliding operation of the edge guide 58.

  Thus, since the supply side guide 64 and the discharge side guide 65 are connected by the connection part 66, by displacing either the supply side guide 64 or the discharge side guide 65, the other is also simultaneously performed. Can be displaced. That is, the slide of the edge guide 58 can be operated while the paper storage space S containing the paper P is closed by the upper outer cover 55. As a result, the edge guide 58 is strongly (or weakly) abutted against the left and right edges of the paper P. Therefore, when the displacement adjustment of the edge guide 58 is necessary, the edge easily and quickly without opening the upper outer cover 55 again. The guide 58 can be displaced.

  As described above, the edge guide 58 of the present embodiment is provided with the supply side guide 64 and the discharge side guide 65 on the front and back sides of the upper outer cover 55, respectively. Therefore, not only the paper P in the paper storage space S but also the left and right edges of the paper P held on the holding surface 61 can be guided. Thereby, it is not necessary to provide the sliding structure of the edge guide 58 separately on the supply side and the discharge side, and the structure can be simplified and the cost can be reduced.

  As shown in FIGS. 4 to 6, near the lower side of the long hole 55b of the upper outer cover 55, for example, a scale 55c for indicating the end in the X-axis direction of the paper P corresponding to the JIS standard A4 size or the like. Is provided. The scale 55c is a hole penetrating the front and back of the upper outer cover 55, and can be confirmed not only from within the paper storage space S but also from the holding surface 61 side. As a result, the edge guide 58 can be displaced in accordance with the stored paper P before the paper storage space S is closed by the upper outer cover 55. Further, by checking the scale 55c, the size of the stored paper P can be known after the paper storage space S is closed. In addition, you may mark by printing, a hollow, a protrusion, etc. on the front and back of the upper outer cover 55 instead of the hole which penetrated the scale 55c.

  Subsequently, as shown in FIGS. 5 and 6, the length guide 63 is slidably engaged with a slide groove 77 formed to extend in the Z-axis direction on the sheet storage space S side of the upper slide tray 57. And an upper end guide 78 attached to the slider 76 and in contact with the upper end of the loaded paper P.

  The slide groove 77 is formed on the left side in FIGS. 5 and 6, and guides the movement of the upper end guide 78 in the vertical direction via the slider 76. The upper end guide 78 is used as a knob for the user to perform a slide operation, and contacts the end of the paper P from above to restrict the movement of the paper P in the Z-axis direction. Thereby, the paper P is set in the paper storage space S in a state where the paper P is also adjusted in the length direction. In particular, when a plurality of sheets P are stacked and set, it is possible to prevent a conveyance failure that may occur due to unevenness of the downstream end in the conveyance direction.

Here, if the sliding structure (the long hole 55b and the slide groove 77) of the edge guide 58 and the length guide 63 is provided for the upper outer cover 55, the structural strength of the upper outer cover 55 is lowered. The same applies to the case where the long hole 55 b and the slide groove 77 are provided in the upper slide tray 57.
However, in the present embodiment, the edge guide 58 is provided on the upper outer cover 55, and the length guide 63 is provided not on the upper outer cover 55 but on the upper slide tray 57. For this reason, it is possible to prevent the structural strength of the upper outer cover 55 and the upper slide tray 57 from being lowered.

  When setting the paper P in the recording medium cassette 5 of the present embodiment, the user first opens the upper outer cover 55, stores the paper P, and brings the length guide 63 into contact with the upper end of the paper P. Next, preferably, the position of the edge guide 58 (supply side guide 64) is roughly adjusted according to the size of the paper P. Thereafter, the upper outer cover 55 is closed, and the guide bar 74 or the plate-like portion 75 serving as an operation member is slid to abut the supply side guide 64 against the right end of the paper P. At this time, the scale 55c is used as an index.

  According to the above configuration, the slide operation of the edge guide 58 can be operated in a state in which the sheet accommodation space S is closed by the upper outer cover 55. For this reason, when the edge guide 58 is improperly abutted against the edge of the paper P, the displacement of the edge guide 58 can be easily adjusted without removing the upper outer cover 55 again.
