で与えられ、θを調整することによりフィード力が調整できる。
巻き掛け角θの調整は、押し上げ部２を操作することにより媒体１との当接部位を押し上げ高さ方向に直交する方向に変位させることにより行われる。図１に示すように、押し上げ部２の媒体１との当接点２０から媒体１の支持面に対しておろした垂線Ｌ１と改頁ローラ３の上記支持面に対して直交する垂線Ｌ２との間隔ｄを媒体１の種類、状態等により調整することにより、最上層ページ１２に対するフィード力が調整できる。すなわち、間隔ｄが狭まると巻き掛け角θが増加してフィード力が増加し、広くなるとフィード力が減少する。
【００１２】
間隔ｄの調整は、例えば押し上げ部２を側方に移動させたり、あるいは、図１（ｂ）に示すように、押し上げ部２の進退角度θ’を調整して行うことも可能であるが、図１（ａ）に示すように、押し上げ部２を支持面に対して垂直方向にのみ進退させることが構造を簡単にするために有効であり、押し上げ部２の先端に側方に移動する可動体５を装着すれば容易に間隔ｄの調整ができる。可動体５は、図１（ａ）に示すように、押し上げ部２の頂部近傍を中心として回転させるように構成することができる。図において矢印Ａで示すように、下方から上方に向けて回転させると改頁ローラ３への巻き掛けが円滑に行われる。
【００１５】
【発明の実施の形態】
図２に本発明が適用された通帳プリンタを示す。受入口６０から通帳（冊子状媒体１）が挿入されると、磁気読み取り部６１において通帳１の表紙等に形成された磁気ストライプの読み取り、および磁気ストライプへの書き込みが行われる。この後、通帳１はイメージセンサ部６２に搬送され、通帳ページマーク、あるいは印字行が読み取られ、印字部６３において記帳される。通帳１は媒体長さ検知により通帳１の開閉が判別され、改頁が必要な場合にはページめくり部６４に搬送される。ページめくり部６４では、通帳１を所定位置にセットした後、閉じ通帳１の表紙めくり、あるいは開き通帳１の中紙のページめくりが行われ、必要に応じて印字部６３での記帳を行った後、利用者に返却する。
【００１６】
ページめくり部６４は、図３ないし図８に示すように、改頁ローラ３と、押さえローラ４とを備える。改頁ローラ３はローラ体と跳ね上げローラとを同軸に配置して形成され、パルスモータ４１により回転駆動される。また、改頁ローラ３の回転力はパルスモータ４１の駆動軸と改頁ローラ３との間に介装されるトルクセンサ４２により検出される。上記改頁ローラ３、および押さえローラ４は大きな摩擦力を得るためにゴム等により形成される。図３に示す通帳１のセット状態において、閉じ側の辺縁１０は押さえローラ４と、この押さえローラ４に対峙するプレッシャローラ４０により挟まれており、開き側の辺縁は改頁ローラ３と、この改頁ローラ３に対峙するプレッシャローラ３０により挟まれて移動が阻止される。最上層ページ１２を改頁ローラ３に所定圧力で押し付けるために、プレッシャローラ３０はスプリング３１により改頁ローラ３側に付勢される。また、プレッシャローラ３０は退避マグネット３２により図７に示すように、通帳１に押圧力を付与しない位置に退避可能とされる。なお、図３ないし図８においては閉じ通帳１の改頁動作が示されているが、開き通帳１の場合には、綴じ代側が押さえローラ４により押し付けられる。
【００１７】
押さえローラ４と改頁ローラ３との中間部位には押し上げ部２が配置される。押し上げ部２は押し上げ用マグネット２１（ソレノイド）により昇降駆動される本体部２２の先端に可動体５を装着して形成され、押し上げ力は押し上げ用マグネット２１と本体部２２との間に介装される圧力センサ２３により検出される。可動体５は偏心位置に設けられる回転軸５０により本体部２２の先端に回動可能に枢支される円柱体で、その外周は摩擦を小さくするために円滑面とされる。この可動体５の回転軸５０の周囲には本体部２２に回動自在に装着されるアイドルローラ２２ａに圧接する摩擦ローラ５１が形成される。さらに本体部２２には可動体駆動用モータ２４（ステッピングモータ）が固定されており、該ステッピングモータ２４を所定ステップ回転駆動することによって回転動力がアイドルローラ２２ａを介して摩擦ローラ５１に伝達され、可動体５を所定角度揺動させる。
【００１８】
ページめくり部６４の動作を説明する。先ず、通帳１のセット状態が確認されると、図４に示すように押し上げ部２が上昇駆動される。セット状態の確認は上流側に配置した媒体検出センサ（図示せず）により行われる。押し上げ部２の上昇により通帳１の中央部は上方に押し上げられて湾曲する。押し上げ圧力は本体部２２と押し上げ用マグネット２１間に介装される圧力センサ２３により検出され、この検出結果に基づいて可動体駆動用モータ２４を駆動して図５に示すように、可動体５を回転軸５０回りに揺動させる。圧力センサ２３の出力と可動体５の揺動角度αとの好ましい関係、すなわち最上層ページ１２のみを確実にフィードするための関係は予め実験的に求められて図示しない記憶装置に対比テーブルとして格納されている。図１に示すように、可動体５の駆動により押し上げ部２の媒体１との当接点２０と、媒体１の支持面に対して直交する改頁ローラ３からの接線との間隔ｄは変化し、間隔ｄが小さくなると通帳１の改頁ローラ３への巻き掛け角θが大きくなり、ｄが大きくなると巻き掛け角θが小さくなる。なお、図５（ａ）は巻き掛け角θを大きくするように可動体５０を駆動した場合、図５（ｂ）は巻き掛け角θを小さくするように駆動した場合を示す。
【００１９】
この状態から改頁ローラ３を図５において矢印Ａ方向、すなわち通帳１の送り方向に回転させる。回転時のトルクはトルクセンサ４２から出力される。トルクセンサ４２、圧力センサ２３からの出力と、可動体５の好ましい関係は図示しない記憶装置にテーブルとして格納されており、トルクセンサ４２の出力と圧力センサ２３の出力値から可動体５の揺動角度が調整される。このような制御条件下で改頁ローラ３を駆動すると、図６に示すように、通帳１の最上層ページ１２、すなわち閉じ通帳１の場合は表紙、開き通帳１の場合は改頁ローラ３に当接しているページのみが改頁ローラ３により上方に膨らませられる。対象ページの膨らみにより押さえローラ４と同軸で回動自在に支持される検知レバー７がフォトインタラプタからなる検知センサ７０を遮り、当該検知センサ７０による検知レバー７の検知により改頁ローラ３の駆動を停止する。改頁ローラ３の停止後、押さえローラ４を逆方向に駆動して図６において矢印Ｂで示すように、綴じ側側縁１０を開き側に移動させると、図７に示すように、最上層ページ１２は湾曲曲率をさらに縮小させながら改頁ローラ３への巻き掛け角θを増加させる。この後、プレッシャローラ３０を退避位置に移動させ、改頁ローラ３を再び図７において矢印Ａ方向に駆動すると、図８に示すように、最上層ページ１２の下層ページをめくることなく最上層ページ１２のみを改頁ローラ３上に跳ね上げることができる。この状態から通帳１を開き側に移動させると、最上層ページ１２は改頁ローラ３により押されて開き、改頁動作が完了する。
【００２０】
なお、以上において、可動体５の揺動角度αは圧力センサ２３とトルクセンサ４２の出力により常時調整される場合を示したが、通帳１の湾曲操作時における圧力センサ２３の出力値、あるいはトルクセンサ４２の出力値により決定された揺動角度αの初期値を操作終了まで使用してもよい。
【００２１】
【発明の効果】
以上の説明から明らかなように、本発明によれば、最上層ページのみを確実にフィードすることができるために、めくり不良、あるいは多数枚めくりを防止できるために、動作信頼性を高めることができる。

BACKGROUND OF THE INVENTION
The present invention relates to an automatic page breaker.
[0002]
[Prior art]
FIG. 9 shows a conventional example of an automatic page breaker used for a passbook printer or the like. In this conventional example, the automatic page breaker includes two pairs of rollers 3, 30 that restrain the binding side edge 10 and the opening side edge 11 of the print medium 1 that is bound to one side edge to form a booklet. 4 and 40 and a push-up unit 2 corresponding to an intermediate part of the print medium 1. The print medium 1 that has been transported through the transport path is first restrained with the binding side edge 10 and the opening side edge 11 sandwiched between the roller pairs 3, 30, 4, and 40, and then driven upward. The central part is pushed up by the push-up part 2 to bend (see FIG. 9A). In this state, when the page breaker roller 3 constituting the opening-side restraint portion is rotated in the direction of arrow A in FIG. 9, that is, in the counterclockwise direction, the state shown in FIG. On the other hand, the uppermost page 12 of the print medium 1 is flipped upward by friction between the page break roller 3 and the print medium 1. Next, the print medium 1 is moved in the direction of arrow B in FIG. 9C, and the uppermost page 12 jumped up on the page break roller 3 is tilted in the opposite direction to complete the page break operation.
[0003]
[Problems to be solved by the invention]
However, the conventional example described above has the following drawbacks. That is, the passbook-like print medium 1 is generally composed of a relatively thick cover and an intermediate sheet thinner than the cover sandwiched between the covers, and the rigidity of the print medium 1 to be paged is different. Further, the surface state of the print medium 1 also changes with time due to dirt and the like, and a magnetic stripe or the like is arranged on the cover, and the friction coefficient varies depending on the contact position with the page break roller 3. In the above-described conventional example in which the push-up unit 2 is pushed up to a predetermined height during a page break operation, if the friction coefficient is different, the page break operation becomes unstable, and page breaks are impossible due to slip, or multiple pages are opened at once. Page turning occurs.
[0005]
An object of the present invention is to solve the above-described drawbacks, and an object of the present invention is to provide an automatic page breaker with high reliability of page break operation. Another object of the present invention is to provide a method for adjusting the page feed force of a booklet-shaped medium for reliably feeding only the uppermost page 12 when performing an automatic page break .
[0006]
[Means for Solving the Problems]
According to the present invention, the object is
A push-up unit 2 that pushes up an intermediate part between the binding side edge 10 and the opening side edge 11 of the medium 1 bound in a booklet shape to bend the medium 1;
A page break roller 3 that presses against the opening side edge 11 of the medium 1 and shifts the uppermost page 12 to the binding side;
The push-up part 2 is a movable body 5 that swings between a binding side edge 10 and an opening side edge 11 of the medium 1 at the tip of a main body part 22 that is driven to move up and down in a direction perpendicular to the support surface of the medium 1. After the intermediate part of the medium 1 is pushed up and bent by the ascending drive, the movable body 5 is swung relative to the main body part 22 to the page break roller 3 of the uppermost page 12. adjust the wrapping angle θ of,
The page-breaking roller 3 is provided with an automatic page-breaking device for a booklet-like medium in which the feed force is adjusted by the winding angle θ and only the uppermost page 12 is swollen upward by rotational driving and shifted to the binding side. Achieved.
Page break device.
[0007]
In the present invention, the booklet-shaped medium 1 is curved by being pushed up by the push-up unit 2, and the page break roller 3 is pressed against the uppermost page 12 of the turning side of the medium 1, that is, the opening side edge 11. When the page breaker roller 3 is driven to rotate, the uppermost page 12 of the medium 1 shifts to the binding side while reducing the curvature of curvature by the frictional force of the page breaker roller 3, and after passing through the page breaker roller 3, the rigidity of the medium 1 itself Jumps up on the page break roller 3. Thereafter, when the medium 1 is moved to the page breaker roller 3 side, the uppermost page 12 that jumps up on the page breaker roller 3 is paged. In order to increase the reliability of the automatic page break, it is essential to shift only the uppermost page 12 and jump up onto the page breaker roller 3. For this reason, the feed force of the uppermost page 12 by the page breaker roller 3 is essential. Adjusted. If the feed force is weak, a page break failure occurs. If the feed force is too strong, pages in the second layer and below are also fed together and multiple pages are turned.
[0008]
In this specification, “top page” refers to a page to be paged. For example, in the case of a passbook, a cover page is used for a bound passbook with a cover page bound. In the case of an open passbook in the opened state, it indicates the page that is opened and is the target of a page break. The “binding side edge 10” refers to the side edge of each page of the booklet-like medium 1 that is bound.
[0009]
When the medium 1 is wound around the page breaker roller 3 at the winding angle θ, the feed force F of the medium 1 by the page breaker roller 3 is defined by assuming that the vertical load is P and the friction coefficient is μ.
[Expression 1]

[0011]
The feed force can be adjusted by adjusting θ.
The winding angle θ is adjusted by operating the push-up unit 2 to displace the contact portion with the medium 1 in a direction perpendicular to the push-up height direction. As shown in FIG. 1, a distance between a perpendicular line L <b> 1 lowered from the contact point 20 of the push-up portion 2 with the medium 1 and the support surface of the medium 1 and a perpendicular line L <b> 2 orthogonal to the support surface of the page break roller 3 By adjusting d according to the type and state of the medium 1, the feed force for the uppermost page 12 can be adjusted. That is, when the distance d is reduced, the winding angle θ is increased and the feed force is increased, and when the interval d is increased, the feed force is reduced.
[0012]
Adjustment of the distance d, for example, or by moving the push-up portion 2 to the side, or, as shown in FIG. 1 (b), row Ukoto is possible to adjust the forward and backward angle of the pushing-up portion 2 theta ' as shown in FIG. 1 (a), it is moved forward and backward only the push-up portion 2 in a direction perpendicular to the support surface is effective for the simplicity of construction, the side on the tip of the push and raising unit 2 If the movable body 5 that moves is mounted, the distance d can be easily adjusted. Movable member 5, as shown in FIG. 1 (a), can be configured to rotate about a near the top of the push-up portion 2. As shown by an arrow A in the figure , when the sheet is rotated from below to above, the page break roller 3 is smoothly wound.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 2 shows a passbook printer to which the present invention is applied. When the passbook (booklet medium 1) is inserted from the receiving port 60, the magnetic reading unit 61 reads the magnetic stripe formed on the cover or the like of the passbook 1 and writes to the magnetic stripe. Thereafter, the bankbook 1 is conveyed to the image sensor unit 62, and a bankbook page mark or print line is read and recorded in the print unit 63. The passbook 1 is discriminated whether the passbook 1 is opened or closed by detecting the length of the medium, and is conveyed to the page turning section 64 when a page break is required. In the page turning unit 64, the passbook 1 is set at a predetermined position, and then the cover of the closed passbook 1 is turned or the middle page of the open passbook 1 is turned, and the printing unit 63 performs the writing as necessary. Then return it to the user.
[0016]
As shown in FIGS. 3 to 8, the page turning portion 64 includes a page break roller 3 and a pressing roller 4. The page break roller 3 is formed by coaxially arranging a roller body and a flip-up roller, and is rotated by a pulse motor 41. The rotational force of the page break roller 3 is detected by a torque sensor 42 interposed between the drive shaft of the pulse motor 41 and the page break roller 3. The page break roller 3 and the pressing roller 4 are made of rubber or the like in order to obtain a large frictional force. In the set state of the bankbook 1 shown in FIG. 3, the edge 10 on the closing side is sandwiched between the pressing roller 4 and the pressure roller 40 facing the pressing roller 4, and the edge on the opening side is the page break roller 3. The movement is prevented by being pinched by the pressure roller 30 facing the page break roller 3. In order to press the uppermost page 12 against the page break roller 3 with a predetermined pressure, the pressure roller 30 is urged toward the page break roller 3 by a spring 31. Further, the pressure roller 30 can be retracted to a position where no pressing force is applied to the bankbook 1, as shown in FIG. 3 to 8 show the page break operation of the closed passbook 1, but in the case of the open passbook 1, the binding margin side is pressed by the pressing roller 4.
[0017]
A push-up portion 2 is disposed at an intermediate portion between the press roller 4 and the page break roller 3. The push-up unit 2 is formed by attaching the movable body 5 to the tip of a main body 22 that is driven up and down by a push-up magnet 21 (solenoid), and the push-up force is interposed between the push-up magnet 21 and the main body 22. It is detected by the pressure sensor 23. The movable body 5 is a cylindrical body that is pivotally supported at the tip of the main body portion 22 by a rotating shaft 50 provided at an eccentric position, and the outer periphery thereof is a smooth surface to reduce friction. A friction roller 51 is formed around the rotary shaft 50 of the movable body 5 so as to be in pressure contact with an idle roller 22 a that is rotatably mounted on the main body 22. Further, a movable body driving motor 24 (stepping motor) is fixed to the main body 22, and rotational power is transmitted to the friction roller 51 via the idle roller 22a by rotating the stepping motor 24 by a predetermined step. The movable body 5 is swung by a predetermined angle.
[0018]
The operation of the page turning unit 64 will be described. First, when the set state of the passbook 1 is confirmed, the push-up unit 2 is driven up as shown in FIG. Confirmation of the set state is performed by a medium detection sensor (not shown) arranged on the upstream side. As the push-up unit 2 moves up, the central part of the bankbook 1 is pushed upward and curved. The push-up pressure is detected by a pressure sensor 23 interposed between the main body 22 and the push-up magnet 21, and the movable body drive motor 24 is driven based on the detection result to move the movable body 5 as shown in FIG. Is swung around the rotation shaft 50. A preferable relationship between the output of the pressure sensor 23 and the swing angle α of the movable body 5, that is, a relationship for reliably feeding only the uppermost page 12 is obtained experimentally in advance and stored as a comparison table in a storage device (not shown). Has been. As shown in FIG. 1, the distance d between the contact point 20 of the push-up unit 2 with the medium 1 and the tangent line from the page breaker roller 3 orthogonal to the support surface of the medium 1 is changed by driving the movable body 5. When the interval d decreases, the winding angle θ around the page break roller 3 of the passbook 1 increases, and when d increases, the winding angle θ decreases. 5A shows a case where the movable body 50 is driven so as to increase the winding angle θ, and FIG. 5B shows a case where the movable body 50 is driven so as to reduce the winding angle θ.
[0019]
From this state, the page break roller 3 is rotated in the direction of arrow A in FIG. Torque during rotation is output from the torque sensor 42. A preferable relationship between the outputs from the torque sensor 42 and the pressure sensor 23 and the movable body 5 is stored as a table in a storage device (not shown), and the swing of the movable body 5 is determined from the output of the torque sensor 42 and the output value of the pressure sensor 23. The angle is adjusted. When the page break roller 3 is driven under such control conditions, as shown in FIG. 6, the uppermost page 12 of the passbook 1, that is, the cover page in the case of the closed passbook 1, and the page break roller 3 in the case of the open passbook 1 are displayed. Only the abutting page is inflated upward by the page break roller 3. A detection lever 7 that is rotatably supported coaxially with the pressing roller 4 by the swelling of the target page blocks the detection sensor 70 that is a photo interrupter, and the detection sensor 7 detects the detection lever 7 to drive the page break roller 3. Stop. After the page break roller 3 is stopped, when the pressing roller 4 is driven in the reverse direction and the binding side edge 10 is moved to the open side as shown by an arrow B in FIG. 6, as shown in FIG. The page 12 increases the winding angle θ around the page break roller 3 while further reducing the curvature of curvature. Thereafter, when the pressure roller 30 is moved to the retracted position and the page break roller 3 is driven again in the direction of the arrow A in FIG. 7, the uppermost page is turned without turning the lower page of the uppermost page 12 as shown in FIG. Only 12 can be flipped up on the page break roller 3. When the bankbook 1 is moved to the opening side from this state, the uppermost page 12 is pushed and opened by the page break roller 3, and the page break operation is completed.
[0020]
In the above description, the swing angle α of the movable body 5 is constantly adjusted by the outputs of the pressure sensor 23 and the torque sensor 42. However, the output value of the pressure sensor 23 or the torque when the passbook 1 is bent. The initial value of the swing angle α determined by the output value of the sensor 42 may be used until the operation is completed.
[0021]
【The invention's effect】
As is clear from the above description, according to the present invention, only the uppermost page can be reliably fed, so that turning failure or turning of a large number of sheets can be prevented. it can.
