Description

本発明は、媒体カセット等の収納部に装填された通帳、帳票や紙幣等の媒体を１枚ずつ分離して繰出す媒体繰出装置に関する。   The present invention relates to a medium feeding device that separates and feeds a medium such as a passbook, a form, or a bill loaded in a storage unit such as a medium cassette one by one.

従来の媒体繰出装置は、媒体カセット等の収納部に装填された最上位の媒体上に錘を載置し、積層された最下位の媒体を繰出しローラに押圧させながら、その繰出しローラを回転させて１枚分の通過を許容するゲートにより１枚ずつ分離して繰出すようにしている（例えば、特許文献１参照）。
また、媒体上に載置される錘は、その錘の側面に設けられた突起部が収納部の内側の側面に設けられた溝に案内されて上下動可能に構成されているが、その突起部を支点として回動してしまい十分に媒体を繰出しローラに押圧することができないことがあった。 A conventional medium feeding device places a weight on the uppermost medium loaded in a storage unit such as a media cassette, and rotates the feeding roller while pressing the lowermost stacked medium against the feeding roller. The gates that allow passage of one sheet are separated and fed out one by one (see, for example, Patent Document 1).
In addition, the weight placed on the medium is configured such that the protrusion provided on the side surface of the weight can be moved up and down by being guided by the groove provided on the inner side surface of the storage portion. In some cases, the medium may not be sufficiently pressed against the feeding roller.

このような問題に鑑み、例えば図５に示すように媒体繰出装置１０１の収納部１０２に装填された媒体Ｐに当接する板材１０５ａと収納部１０２の繰出し口１１１側の側壁１０３に当接する板材１０５ｂとにより錘１０５を形成し、最下位の媒体Ｐを繰出しローラ１０６に押圧させるようにすることが考えられる。
特開２００６−８２９４６号公報（段落「００１１」〜段落「００１５」、図１） In view of such a problem, for example, as shown in FIG. 5, a plate member 105 a that contacts the medium P loaded in the storage unit 102 of the medium feeding device 101 and a plate member 105 b that contacts the side wall 103 on the supply port 111 side of the storage unit 102. Thus, it is conceivable to form the weight 105 and press the lowermost medium P against the feeding roller 106.
JP 2006-82946 A (paragraphs “0011” to “0015”, FIG. 1)

しかしながら、上述した図５に示す従来の技術においても、収納部１０２に装填された媒体Ｐが少なくなると繰出しローラ１０６と分離ローラ１０７の接線と収納部１０２の側壁に当接する板材１０５ｂの面の延長線が交わる点から収納部１０２の側壁に当接する板材１０５ｂの先端１０５ｄまでの長さＬ２がその点から媒体Ｐと繰出しローラ１０６の接点までの長さＬ１より短くなってしまうため、先端１０５ｄを支点とした回転モーメントが発生して錘１０５は浮き上がり、媒体Ｐを繰出しローラ１０６に押圧させる力が不十分になるため繰出し不良が発生するという問題がある。   However, also in the conventional technique shown in FIG. 5 described above, when the medium P loaded in the storage unit 102 decreases, the tangent line of the feeding roller 106 and the separation roller 107 and the extension of the surface of the plate 105b that contacts the side wall of the storage unit 102 are extended. Since the length L2 from the point where the lines intersect to the front end 105d of the plate member 105b contacting the side wall of the storage portion 102 is shorter than the length L1 from that point to the contact point of the medium P and the feeding roller 106, the front end 105d There is a problem that a rotation moment as a fulcrum is generated, the weight 105 is lifted, and a force for pressing the medium P against the feeding roller 106 becomes insufficient, so that feeding failure occurs.

また、中央部が錘１０５側、両端部が板材１０４側になるように湾曲した媒体Ｐが装填された場合、その媒体Ｐが残り少なくなると媒体Ｐと繰出しローラ１０６との間に隙間ができてしまうため、媒体Ｐを繰出しローラ１０６に押圧させる力が不十分になるため繰出し不良が発生するという問題がある。
さらに、中央部が板材１０４側、両端部が錘１０５側になるように湾曲した媒体Ｐが装填された場合、その媒体Ｐが残り少なくなると媒体Ｐの先端部が分離ゲート１０８の上方に位置するようになり、正確に繰出し口１１１へ導くことができず繰出し不良が発生するという問題がある。 In addition, when the medium P that is curved so that the center portion is on the weight 105 side and both end portions are on the plate material 104 side is loaded, a gap is formed between the medium P and the feeding roller 106 when the medium P is reduced. Therefore, there is a problem that a feeding failure occurs because the force for pressing the medium P against the feeding roller 106 becomes insufficient.
Further, when the medium P curved so that the central portion is on the plate material 104 side and both ends are on the weight 105 side is loaded, the tip portion of the medium P is positioned above the separation gate 108 when the remaining amount of the medium P decreases. Therefore, there is a problem in that it cannot be accurately guided to the feeding port 111 and a feeding failure occurs.

本発明は、このような問題を解決することを課題とする。   An object of the present invention is to solve such a problem.

そのため、本発明は、繰出し方向に傾斜させた底部に積層させて媒体を収納する収納部と、その収納部の最下位の媒体を１枚ずつ分離して繰出す繰出しローラとを備えた媒体繰出装置において、媒体を押圧する傾斜面と、収納部の繰出し方向の壁面に接する垂直面とを有し、前記傾斜面または前記傾斜面が延長された面と前記垂直面または前記垂直面が延長された面との交点から前記垂直面の上端までの長さが前記交点から繰出しローラと前記傾斜面とが接する接点までの長さ以上になるように形成され、収納部の最上位の媒体に載置される媒体押さえを設けたことを特徴とする。   For this reason, the present invention provides a medium feeding device that includes a storage unit that stores media stacked on a bottom inclined in a feeding direction, and a feeding roller that separates and feeds the lowest media in the storage unit one by one. The apparatus has an inclined surface for pressing the medium and a vertical surface in contact with a wall surface in the feeding direction of the storage unit, and the inclined surface or the surface on which the inclined surface is extended and the vertical surface or the vertical surface is extended. Is formed so that the length from the intersection point to the upper end of the vertical surface is not less than the length from the intersection point to the contact point where the feeding roller and the inclined surface contact each other, and is mounted on the uppermost medium of the storage unit. A medium presser is provided.

また、前記媒体押さえの傾斜面を形成する部材に、媒体押さえの重心が繰出しローラの上方に位置するように錘を設けたことを特徴とする。
さらに、前記媒体押さえの傾斜面を形成する部材を、端部が繰出しローラの近傍の反繰出し方向に位置するように形成された板材とし、前記錘を、前記板材の傾斜面の反対面に固着させたことを特徴とする。 Further, the member forming the inclined surface of the medium press is provided with a weight so that the center of gravity of the medium press is positioned above the feeding roller.
Further, the member that forms the inclined surface of the medium pressing member is a plate material that is formed so that the end portion is positioned in the counter-feeding direction near the feeding roller, and the weight is fixed to the opposite surface of the inclined surface of the plate material. It was made to be characterized.

このようにした本発明は、収納部に装填された媒体が残り少なくなった場合、中央部が媒体押さえ側、両端部が底部側になるように湾曲した媒体が装填された場合、さらに中央部が底部側、両端部が媒体押さえ側になるように湾曲した媒体が装填された場合であっても、その媒体を分離ローラに充分な力で押圧することができ、媒体を確実に繰出すことができるようになるという効果が得られる。   In the present invention as described above, when the medium loaded in the storage portion is reduced, when the curved medium is loaded so that the central portion is on the medium pressing side and both end portions are on the bottom side, the central portion is further Even when a curved medium is loaded so that the bottom side and both ends are on the medium pressing side, the medium can be pressed against the separation roller with sufficient force, and the medium can be fed out reliably. The effect of being able to do it is obtained.

以下、図面を参照して本発明による媒体繰出装置の実施例を説明する。   Embodiments of a medium feeding device according to the present invention will be described below with reference to the drawings.

図１は第１の実施例における媒体繰出装置の側面を示す説明図である。
図１において、１は媒体繰出装置であり、装填された通帳、帳票や紙幣等の媒体Ｐを１枚ずつ分離して繰出すものである。この媒体繰出装置１は、例えば銀行等の金融機関の現金自動預払機、通帳発行装置、帳票発行装置等に組み込まれるものである。
なお、本実施例では媒体Ｐを通帳として説明するものとする。 FIG. 1 is an explanatory view showing a side surface of a medium feeding device in the first embodiment.
In FIG. 1, reference numeral 1 denotes a medium feeding device that separates and feeds loaded media P such as bankbooks, forms, and banknotes one by one. The medium feeding device 1 is incorporated in an automatic teller machine, a passbook issuing device, a form issuing device, or the like of a financial institution such as a bank.
In this embodiment, the medium P is described as a passbook.

２は収納部であり、媒体Ｐを積層して収納するものである。この収納部２は図中矢印Ａで示す繰出し方向に傾斜させた底部を形成する底板４の上に媒体Ｐを積層して収納する。
５は媒体押さえであり、収納部２に収納された最上位の媒体Ｐ上に載置されるものである。この媒体押さえ５は、略レ字状に形成され、媒体Ｐに当接してその媒体Ｐを押圧する傾斜面を形成する板材５ａ、その板材５ａの上面（媒体Ｐを押圧する傾斜面の反対面）に固着され、垂直方向の一面が繰出し方向側の収納部２の壁面２ａに接するように形成された板材５ｂ、および端部が繰出しローラの近傍の反繰出し方向に位置するように形成された板材５ａ、５ｂのその端部（反繰出し方向の後端部）の上面（媒体Ｐを押圧する傾斜面の反対面）に固着された錘５ｃ（例えば板状のもの）で形成されている。 A storage unit 2 stores the medium P in a stacked manner. The storage portion 2 stores the medium P in a stacked manner on a bottom plate 4 that forms a bottom portion inclined in the feeding direction indicated by an arrow A in the drawing.
A medium press 5 is placed on the uppermost medium P stored in the storage unit 2. The medium presser 5 is formed in a substantially letter shape, and forms a sloping surface that abuts against the medium P and presses the medium P, and an upper surface of the plate 5a (the opposite surface of the sloping surface that presses the medium P). ) And a plate member 5b formed so that one surface in the vertical direction is in contact with the wall surface 2a of the storage portion 2 on the feeding direction side, and the end portion is formed so as to be positioned in the counter feeding direction in the vicinity of the feeding roller. It is formed of a weight 5c (for example, a plate-like material) fixed to the upper surface (the opposite surface of the inclined surface that presses the medium P) of the end portions (rear end portions in the counter-feeding direction) of the plate materials 5a and 5b.

また、この媒体押さえ５は、その側面に図示しない突起部が設けられ、収納部２の内側の側面に設けられた溝に案内されて上下動可能に構成されている。
６は繰出しローラであり、底板４に設けられた孔から外周面が突出するように収納部２の底部に設けられたものである。この繰出しローラ６は、媒体Ｐの搬送が容易になるように外周面の一部または全部にゴム等の高摩擦部材が取り付けられており、図示しないモータ等の駆動手段やその駆動を伝達する駆動伝達手段により正逆回転可能に構成され、図中反時計方向に回転して媒体押さえ５および媒体Ｐの自重により押圧されている最下位の媒体Ｐを矢印Ａが示す繰出し方向に搬送する。 The medium presser 5 is provided with a projection (not shown) on its side surface, and is guided by a groove provided on the inner side surface of the storage unit 2 so as to be movable up and down.
Reference numeral 6 denotes a feeding roller, which is provided at the bottom of the storage portion 2 so that the outer peripheral surface protrudes from a hole provided in the bottom plate 4. The feeding roller 6 has a high friction member such as rubber attached to a part or the whole of the outer peripheral surface so that the medium P can be easily conveyed, and a driving means such as a motor (not shown) or a drive for transmitting the driving. The transmission means is configured to be able to rotate in the forward and reverse directions, and rotates in the counterclockwise direction in the drawing to convey the lowest medium P pressed by the weight of the medium presser 5 and the medium P in the feeding direction indicated by the arrow A.

７は分離ローラであり、繰出しローラ６の繰出し方向の下流に配置され、媒体Ｐ搬送が容易になるように外周面の一部または全部にゴム等の高摩擦部材が取り付けられており、図示しないモータ等の駆動手段やその駆動を伝達する駆動伝達手段により繰出しローラ６と同期して同方向に回転可能に構成されている。
８は分離ゲートであり、収納部２の開口部である媒体繰出し口１１の近傍に配置され、分離ゲート軸９に回動自在に取り付けれ、収納部２から繰出された媒体Ｐを１冊ずつ分離するためのものである。 A separation roller 7 is disposed downstream of the feeding roller 6 in the feeding direction, and a high friction member such as rubber is attached to a part or the whole of the outer peripheral surface so that the medium P can be easily conveyed. It is configured to be able to rotate in the same direction in synchronism with the feeding roller 6 by a driving means such as a motor or a driving transmission means for transmitting the driving.
Reference numeral 8 denotes a separation gate, which is disposed in the vicinity of the medium feeding port 11 which is an opening of the storage unit 2, is rotatably attached to the separation gate shaft 9, and separates the medium P fed from the storage unit 2 one by one. Is to do.

この分離ゲート８は対向配置された分離ローラ７との間が媒体Ｐの１冊の厚さよりやや広い間隔となるように配置されている。また、この分離ゲート８は収納部２の壁面に設けられたスプリング１０で分離ローラ７側に付勢されている。
ここで、図１は収納部２に一冊の媒体Ｐが収納された状態を示し、この図１において、接点１５は収納部２に収納された媒体Ｐと繰出しローラ６との接点を示し、接点１６は繰出された媒体Ｐと分離ローラ７との接点を示し、接点１７は媒体押さえ５の板材５ｂの先端５ｄと収納部２の壁面２ａの接点を示している。 The separation gate 8 is arranged so that the gap between the separation roller 8 and the opposed separation roller 7 is slightly wider than the thickness of one medium P. The separation gate 8 is urged toward the separation roller 7 by a spring 10 provided on the wall surface of the storage portion 2.
Here, FIG. 1 shows a state in which a single medium P is stored in the storage unit 2. In FIG. 1, a contact 15 indicates a contact point between the medium P stored in the storage unit 2 and the feeding roller 6. A contact 16 indicates a contact between the fed medium P and the separation roller 7, and a contact 17 indicates a contact between the tip 5 d of the plate 5 b of the medium presser 5 and the wall surface 2 a of the storage portion 2.

また、交点１８は、接点１５および接点１６を通る直線２０と板材５ｂと壁面２ａの接線２１との交点を示している。
この接点１５と交点１８の距離をＬ１、接点１７と交点１８の距離をＬ２とすると、媒体押さえ５の板材５ｂは、Ｌ２がＬ１以上になるように形成されている。
すなわち、媒体押さえ５は、板材５ａの傾斜面またはその傾斜面が延長された面と板材５ｂの垂直面またはその垂直面が延長された面との交線（交点１８）から板材５ｂの垂直面の上端５ｄまでの長さＬ２が交線（交点１８）から繰出しローラ６と板材５ａの傾斜面とが接する線（接点１５）までの長さＬ１以上になるように形成されている。 An intersection 18 indicates an intersection of the straight line 20 passing through the contact 15 and the contact 16, the plate 5b, and the tangent 21 of the wall surface 2a.
When the distance between the contact point 15 and the intersection point 18 is L1, and the distance between the contact point 17 and the intersection point 18 is L2, the plate member 5b of the medium presser 5 is formed so that L2 is L1 or more.
That is, the medium presser 5 is a vertical surface of the plate 5b from an intersection line (intersection 18) between the inclined surface of the plate 5a or a surface on which the inclined surface is extended and the vertical surface of the plate 5b or the surface on which the vertical surface is extended. The length L2 up to the upper end 5d is formed to be equal to or longer than the length L1 from the intersection line (intersection point 18) to the line (contact point 15) where the feeding roller 6 and the inclined surface of the plate member 5a contact each other.

このように媒体押さえ５を形成することで接点１７を支点とした回転モーメントにより媒体押さえ５が浮き上がることがなくなる。
また、媒体押さえ５の板材５ａの繰出し方向の先端５ｅは接線２１の直近（近傍）に位置するように形成され、板材５ａ、５ｂの端部は接点１５の反繰出し方向に位置するように形成されている。 By forming the medium presser 5 in this way, the medium presser 5 is not lifted by a rotational moment with the contact point 17 as a fulcrum.
Further, the tip 5e of the medium presser 5 in the feeding direction of the plate material 5a is formed so as to be positioned in the immediate vicinity (near) of the tangent line 21, and the end portions of the plate materials 5a, 5b are formed so as to be positioned in the counterfeeding direction of the contact 15. Has been.

さらに、錘５ｃは媒体押さえ５の重心が接点１５の上方に位置するように配置されている。
上述した構成の作用について説明する。
なお、各実施例において媒体繰出装置１が行う動作は図示しないメモリ等の記憶手段に記憶された制御プログラム（ソフトウェア）に基づいて図示しない制御手段により制御されるものとする。 Further, the weight 5 c is arranged so that the center of gravity of the medium presser 5 is located above the contact 15.
The operation of the above configuration will be described.
In each embodiment, the operation performed by the medium feeding device 1 is controlled by a control unit (not shown) based on a control program (software) stored in a storage unit such as a memory (not shown).

媒体繰出装置１の収納部２に媒体Ｐが装填された状態で図示しない上位装置から媒体Ｐを繰出す指示を受信すると、図示しない制御手段により媒体Ｐの繰出し動作が開始される。
図１において、図示しない駆動手段により繰出しローラ６および分離ローラ７が反時計方向に回転すると媒体押さえ５により繰出しローラ６に押圧された最下位の媒体Ｐは繰出し口１１の方向へ繰出され、繰出された媒体Ｐの先端が繰出し口１１を１冊ずつ通過して図示しない媒体搬送路へ送り出される。 When an instruction to feed out the medium P is received from a host device (not shown) in a state where the medium P is loaded in the storage unit 2 of the medium feeding device 1, a feeding operation of the medium P is started by a control unit (not shown).
In FIG. 1, when the feeding roller 6 and the separation roller 7 are rotated counterclockwise by a driving means (not shown), the lowest medium P pressed against the feeding roller 6 by the medium presser 5 is fed toward the feeding port 11 and fed out. The leading edge of the medium P thus passed passes through the feeding port 11 one by one and is sent out to a medium conveyance path (not shown).

このとき、板材５ａ、５ｂの端部は接点１５の反繰出し方向に位置するように形成され、また媒体押さえ５の重心が接点１５の上方に位置するため、媒体Ｐは媒体押さえ５により充分な力で繰出しローラ６に押圧され、確実に繰出される。
特に、収納部２に装填された媒体Ｐが残り１冊になった場合であっても、媒体押さえ５の板材５ｂは、上述したＬ２がＬ１以上になるように形成されているため、接点１７を支点とした回転モーメントにより媒体押さえ５が浮き上がることなく、媒体Ｐを繰出しローラ６に押圧することができる。 At this time, the end portions of the plate members 5 a and 5 b are formed so as to be positioned in the counter-feeding direction of the contact 15, and the center of gravity of the medium presser 5 is located above the contact 15. It is pressed by the feeding roller 6 with force and is reliably fed out.
In particular, even when the remaining medium P loaded in the storage section 2 is one, the plate 5b of the medium presser 5 is formed so that the above-described L2 is equal to or greater than L1, and therefore the contact 17 The medium presser 5 can be pressed against the feeding roller 6 without the medium presser 5 being lifted by the rotation moment about the fulcrum.

また、媒体押さえ５の板材５ａの繰出し方向の先端５ｅが接線２１の直近に位置するように形成されているため、繰出し方向の先端部が湾曲した媒体Ｐであってもその先端部を媒体押さえ５が充分な力で押圧し、媒体Ｐの湾曲した部位を修正して確実に媒体繰出し口１１へ案内することができる。
さらに、錘５ｃを板材５ａ、５ｂの反繰出し方向側の後端部の上面に固着し、錘５ｃと底板４との間に空間を形成するようにしているため、反繰出し方向側の端部が湾曲した媒体Ｐにより媒体押さえ５を押し上げられることなく、媒体押さえ５は媒体Ｐを繰出しローラ６に充分な力で押圧することができる。 Further, since the tip 5e in the feeding direction of the plate 5a of the medium presser 5 is formed so as to be positioned in the immediate vicinity of the tangent line 21, even if the medium P has a curved leading end in the feeding direction, the tip of the medium presser 5 5 is pressed with a sufficient force, and the curved portion of the medium P can be corrected and reliably guided to the medium feeding port 11.
Furthermore, since the weight 5c is fixed to the upper surface of the rear end portion of the plate members 5a and 5b on the side opposite to the feeding direction and a space is formed between the weight 5c and the bottom plate 4, the end portion on the side opposite to the feeding direction. The medium press 5 can press the medium P against the feeding roller 6 with a sufficient force without being pushed up by the medium P curved.

図２は第１の実施例における中央部が媒体押さえ側、両端部が底板側に湾曲した媒体が装填された場合の説明図であり、図２において、媒体Ｐは、その中央部が媒体押え５側、両端部が底板４側になるように湾曲したものを示している。このように中央部が媒体押え５側、両端部が底板４側になるように湾曲した媒体Ｐが装填された場合であっても、媒体押さえ５は、その重心が接点１５の上方に位置するように形成されているため、図中実線で示すように媒体Ｐは媒体押さえ５により充分な力で繰出しローラ６に押圧され、確実に繰出される。   FIG. 2 is an explanatory diagram when a medium having a curved center portion is loaded on the medium pressing side and both end portions are bent to the bottom plate side in the first embodiment. In FIG. 5 is shown in which both ends are curved so as to be on the bottom plate 4 side. Thus, even when the medium P curved so that the center part is on the side of the medium presser 5 and both ends are on the side of the bottom plate 4 is loaded, the center of gravity of the medium presser 5 is located above the contact 15. Therefore, as shown by the solid line in the drawing, the medium P is pressed by the feeding roller 6 with a sufficient force by the medium presser 5 and is reliably fed out.

図３は第１の実施例における中央部が底板側、両端部が媒体押さえ側に湾曲した媒体が装填された場合の説明図であり、図３において、媒体Ｐは、その中央部が底板４側、両端部が媒体押え５側になるように湾曲したものを示している。このように中央部が底板４側、両端部が媒体押え５側になるように湾曲した媒体Ｐが装填された場合であっても、錘５ｃと底板４との間に充分な空間を形成するようにしているため、媒体Ｐの反繰出し方向側の端部により媒体押さえ５が押し上げられることなく、媒体押さえ５は媒体Ｐを繰出しローラ６に充分な力で押圧することができる。   FIG. 3 is an explanatory diagram of a case where a medium with a curved center portion is loaded on the bottom plate side and both end portions are curved on the medium pressing side in the first embodiment. In FIG. The side and both ends are curved so that they are on the medium presser 5 side. Thus, even when the medium P curved so that the center portion is on the bottom plate 4 side and both ends are on the medium presser 5 side is loaded, a sufficient space is formed between the weight 5 c and the bottom plate 4. Therefore, the medium presser 5 can press the medium P against the feed roller 6 with a sufficient force without the medium presser 5 being pushed up by the end of the medium P on the side opposite to the feed-out direction.

このように構成された媒体繰出装置１は収納部２に装填された媒体Ｐを最後の１冊まで正確に繰出し口１１へ導き、１冊ずつ分離して繰出すことができる。
以上説明したように、第１の実施例では、収納部２に装填された媒体Ｐが残り１冊になった場合であっても、接点１７を支点とした回転モーメントにより媒体押さえ５が浮き上がることがないようにしたため、媒体Ｐを繰出しローラ６に充分な力で押圧することができ、媒体Ｐを確実に繰出すことができるようになるという効果が得られる。 The medium feeding device 1 configured in this manner can accurately guide the medium P loaded in the storage unit 2 to the feeding port 11 up to the last one and separate and feed one by one.
As described above, in the first embodiment, the medium presser 5 is lifted by the rotational moment with the contact point 17 as a fulcrum even when the remaining medium P is loaded in the storage section 2. Therefore, the medium P can be pressed against the feeding roller 6 with a sufficient force, so that the medium P can be reliably fed out.

また、中央部が媒体押え５側、両端部が底板４側になるように湾曲した媒体Ｐが装填された場合であっても、媒体押さえ５は、その重心が接点１５の上方に位置するように形成されているため、媒体Ｐを繰出しローラ６に充分な力で押圧することができ、媒体Ｐを確実に繰出すことができるようになるという効果が得られる。
さらに、中央部が底板側、両端部が媒体押さえ側になるように湾曲した媒体Ｐが装填された場合であっても、錘５ｃと底板４との間に充分な空間を形成するようにしているため、媒体Ｐの反繰出し方向側の端部により媒体押さえ５が押し上げられることなく、媒体Ｐを繰出しローラ６に充分な力で押圧することができ、媒体Ｐを確実に繰出すことができるようになるという効果が得られる。 Further, even when the medium P curved so that the center portion is on the side of the medium presser 5 and both ends are on the side of the bottom plate 4 is loaded, the center of gravity of the medium presser 5 is positioned above the contact 15. Therefore, the medium P can be pressed against the feeding roller 6 with sufficient force, and the effect that the medium P can be reliably fed out is obtained.
Furthermore, even when the medium P is bent so that the center portion is on the bottom plate side and both end portions are on the medium pressing side, a sufficient space is formed between the weight 5c and the bottom plate 4. Therefore, the medium P can be pressed against the feeding roller 6 with a sufficient force without being pushed up by the end of the medium P on the side opposite to the feeding direction, and the medium P can be reliably fed out. The effect of becoming like this is acquired.

また、繰出し方向の先端部が湾曲した媒体Ｐであっても、その先端部を媒体押さえ５が充分な力で押圧するようにしたため、媒体Ｐの湾曲した部位を修正して確実に媒体繰出し口１１へ案内することができるという効果が得られる。   Even if the medium P has a curved leading end in the feeding direction, the medium presser 5 is pressed against the leading end with a sufficient force. Therefore, the curved portion of the medium P is corrected to ensure the medium feeding port. 11 can be obtained.

図４は第２の実施例における媒体繰出装置の側面を示す説明図である。
第１の実施例の構成と異なる部分を以下に説明する。
図４において、４１は収納部２の底部を構成する底板である。底板４１ａは繰出しローラ６の繰出し方向の底部、底板４１ｂは繰出しローラ６の反繰出し方向の底部を形成するものである。 FIG. 4 is an explanatory view showing a side surface of the medium feeding device in the second embodiment.
Parts different from the configuration of the first embodiment will be described below.
In FIG. 4, reference numeral 41 denotes a bottom plate constituting the bottom of the storage unit 2. The bottom plate 41a forms the bottom of the feeding roller 6 in the feeding direction, and the bottom plate 41b forms the bottom of the feeding roller 6 in the non-feeding direction.

底板４１ａおよび底板４１ｂは繰出し方向に傾斜させて形成され、底板４１ｂの傾斜角は底板４１ａの傾斜角より緩くなるように、例えば水平または水平に近くなるように形成されている。
５ｆは錘であり、媒体押さえ５の板材５ａ、５ｂの反繰出し方向側の後端部の上面に固着され、さらにその後端の近傍で上方向に屈折するように形成されている。 The bottom plate 41a and the bottom plate 41b are formed to be inclined in the feeding direction, and the inclination angle of the bottom plate 41b is formed so as to be looser than the inclination angle of the bottom plate 41a, for example, to be horizontal or nearly horizontal.
Reference numeral 5f denotes a weight, which is fixed to the upper surface of the rear end portion of the medium presser 5 on the side opposite to the feeding direction of the plate members 5a and 5b, and is further refracted upward in the vicinity of the rear end.

このように底板４１ｂと錘５ｆとで形成される空間が広くなるようにしている。
媒体押さえ５の板材５ａの繰出し方向の先端５ｅは接線２１の直近に位置するように形成され、板材５ａ、５ｂの端部は接点１５の反繰出し方向に位置するように形成され、錘５ｃは媒体押さえ５の重心が接点１５の上方に位置するように配置されているのは第１の実施例と同様である。 In this way, the space formed by the bottom plate 41b and the weight 5f is widened.
The tip 5e in the feeding direction of the plate 5a of the medium press 5 is formed so as to be positioned in the immediate vicinity of the tangent line 21, the ends of the plates 5a, 5b are formed so as to be positioned in the counter-feeding direction of the contact 15, and the weight 5c is Similar to the first embodiment, the medium presser 5 is arranged so that its center of gravity is located above the contact 15.

なお、上述した第１の実施例と同様の部分は、同一の符号を付してその説明を省略する。
上述した構成の作用について説明する。
収納部２に媒体Ｐが装填された状態で図示しない上位装置から媒体Ｐを繰出す指示を受信すると、図示しない制御手段により媒体Ｐの繰出し動作が開始される。 Note that parts similar to those of the first embodiment described above are denoted by the same reference numerals and description thereof is omitted.
The operation of the above configuration will be described.
When an instruction to feed out the medium P is received from a host device (not shown) in a state where the medium P is loaded in the storage unit 2, a feeding operation of the medium P is started by a control unit (not shown).

図４において、図示しない駆動手段により繰出しローラ６および分離ローラ７が反時計方向に回転すると媒体押さえ５により繰出しローラ６に押圧された最下位の媒体Ｐは繰出し口１１の方向へ繰出され、繰出された媒体Ｐの先端が繰出し口１１を１冊ずつ通過して図示しない媒体搬送路へ送り出される。
このとき、図４に示すように中央部が媒体押さえ５側、両端部が底板４側になるように湾曲した媒体Ｐが装填された場合であっても、底板４１ｂで確保された空間に媒体Ｐが湾曲した状態で収められ、媒体Ｐは媒体押さえ５により充分な力で繰出しローラ６に押圧され、確実に繰出される。 In FIG. 4, when the feeding roller 6 and the separation roller 7 are rotated counterclockwise by a driving means (not shown), the lowest medium P pressed against the feeding roller 6 by the medium presser 5 is fed toward the feeding port 11 and fed out. The leading edge of the medium P thus passed passes through the feeding port 11 one by one and is sent out to a medium conveyance path (not shown).
At this time, as shown in FIG. 4, even in the case where the medium P curved so that the center part is on the medium presser 5 side and both ends are on the bottom plate 4 side is loaded, the medium is placed in the space secured by the bottom plate 41b. P is stored in a curved state, and the medium P is pressed by the feeding roller 6 with sufficient force by the medium presser 5 and is reliably fed out.

また、中央部が底板４側、両端部が媒体押さえ５側になるように湾曲した媒体Ｐが装填された場合であっても、錘５ｆと底板４１ｂとの間に充分な空間を形成するようにしているため、媒体Ｐの反繰出し方向側の端部により媒体押さえ５を押し上げられることなく、媒体押さえ５は媒体Ｐを繰出しローラ６に充分な力で押圧することができる。
以上説明したように、第２の実施例では、第１の実施例の効果に加え、中央部が媒体押さえ５側、両端部が底板４側になるように湾曲した媒体Ｐが装填された場合であっても、底板４１ｂで確保された空間に媒体Ｐが湾曲した状態で収められ、媒体押さえ５は充分な力で媒体Ｐを繰出しローラ６に押圧することができ、媒体Ｐをより確実に繰出すことができるようになるという効果が得られる。 Further, even when the medium P curved so that the center portion is on the bottom plate 4 side and both ends are on the medium presser 5 side is loaded, a sufficient space is formed between the weight 5f and the bottom plate 41b. Therefore, the medium presser 5 can press the medium P against the feed roller 6 with a sufficient force without the medium presser 5 being pushed up by the end of the medium P on the side opposite to the feed-out direction.
As described above, in the second embodiment, in addition to the effects of the first embodiment, when the medium P curved so that the center portion is on the medium presser 5 side and both end portions are on the bottom plate 4 side is loaded. Even in such a case, the medium P is stored in a curved state in the space secured by the bottom plate 41b, and the medium presser 5 can press the medium P against the feeding roller 6 with a sufficient force, so that the medium P is more reliably secured. The effect of being able to pay out is obtained.

また、中央部が底板４側、両端部が媒体押さえ５側になるように湾曲した媒体Ｐが装填された場合であっても、錘５ｆと底板４１ｂとの間に充分な空間を形成するようにしているため、媒体Ｐの反繰出し方向側の端部により媒体押さえ５が押し上げられることなく、媒体押さえ５は充分な力で媒体Ｐを繰出しローラ６に押圧することができ、媒体Ｐをより確実に繰出すことができるようになるという効果が得られる。   Further, even when the medium P curved so that the center portion is on the bottom plate 4 side and both ends are on the medium presser 5 side is loaded, a sufficient space is formed between the weight 5f and the bottom plate 41b. Therefore, the medium presser 5 can press the medium P against the feed roller 6 with a sufficient force without the medium presser 5 being pushed up by the end of the medium P on the side opposite to the feeding direction. The effect that it can be reliably fed out is obtained.
