Description

  The present invention relates to a sheet roller, and more particularly to a financial automation apparatus having a partially stacked sheet roller structure that can reduce costs and improve quality.

  Financial automation equipment is automation equipment that can provide basic financial services, such as deposits and withdrawals, without the need for bank staff without being bound by time and place in relation to financial services.

  Financial automation equipment is broadly divided into cash payment machines and cash deposit machines, depending on whether or not there are deposits and withdrawals. Recently, financial automation equipment is not only for cash deposits and withdrawals, but also for check deposits and withdrawals, bankbook arrangements, and transfer charges. It is used for various purposes such as payment and ticket sales.

  For financial automation equipment as described above, paper media loaded in a media storage unit such as a cassette box is dispensed one by one to dispense cash or checks, etc. A medium separating and accumulating unit for accumulating in the storage unit is provided.

  The medium separating and accumulating unit picks up a paper medium one by one from the medium storage unit, and transports the paper medium that is mounted adjacent to the pickup roller and separated one by one by the pickup roller. A feed roller that flows into the path, a gate roller that rotates while maintaining an overlapped state with the feed roller, and a pinch roller that tightly contacts a paper medium to the feed roller can be provided.

  Here, at both ends of the rotating shaft on which the gate roller is mounted, a sheet roller on which a sheet for pushing out the medium to be deposited and withdrawn is formed. Such a sheet roller must be avoided from the conveyance path when the medium is dispensed, and must enter the conveyance path and deposit when the medium is deposited and contact the loaded medium.

  Thus, the sheet roller must be separated or avoided from the conveyance path so that it does not come into contact with the medium at the time of withdrawal, and is present on the conveyance path so as to contact the medium only at the time of deposit. It is possible to adopt a structure that avoids or retracts the rotating shaft itself. However, when such a structure is adopted, another structure for avoiding the sheet roller must be added, resulting in an increase in production cost and a complicated conveyance path structure near the medium separating and accumulating unit. There was a problem.

  In order to solve such a problem, a partially stacked sheet roller in which a sheet is only partially formed on the outer peripheral surface of the sheet roller can be used. When using a partially stacked sheet roller, the gate shaft or the rotation shaft on which the sheet roller is mounted does not rotate at the time of withdrawal, and the sheet formed on the sheet roller is not in contact with the medium. Since the sheet roller rotates together with the shaft, the medium can contact the sheet and be accumulated in the medium storage unit. However, when the partially stacked sheet roller is used, there is no contact between the sheet already stacked in the medium storage unit and the sheet roller, and thus it is not possible to secure a sufficient space for the newly stacked medium. There was a problem.

  The present invention provides a sheet roller that can reduce the production cost while using a partial stack sheet roller, and does not cause a medium stacking failure when depositing or stacking.

  The present invention uses at least two partial stack sheet rollers, and includes a phase recovery means such as a spring clutch and a stopper between the sheet rollers, and the role of the radial sheet roller by using the frictional force between the stack sheet and the medium during stacking. Provided is a sheet roller capable of completely performing the above.

  The present invention provides a sheet roller that prevents the sheet roller from being disturbed by avoiding the sheet roller in the medium conveyance path by using the elastic restoring force of the phase recovery means at the time of medium separation to make the phase between the sheet rollers coincide.

  According to one embodiment of the present invention for achieving the object of the present invention described in detail, one rotation of the medium separating and accumulating unit that separates the medium from the medium accommodating unit and accumulates the medium conveyed to the medium accommodating unit A sheet roller provided on the shaft, provided on the rotating shaft so as to rotate together with the rotating shaft, and a fixed roller having a plurality of fixed elastic sheets spaced apart on the outer peripheral surface; A plurality of idle elastic sheets that are installed on the rotating shaft so as to be positioned on one side and are spaced apart from each other are formed on the outer peripheral surface, and can rotate relative to the fixed roller as the rotating shaft rotates. It is possible to provide a sheet roller including an idle roller and a phase recovery unit that removes a phase difference caused by relative rotation of the idle roller with respect to the fixed roller by using an elastic force.

  By configuring as described above, the sheet roller is prevented from coming into contact with the medium at the time of dispensing or separating the medium, and the sheet roller and the medium are not only brought into contact at the time of depositing or collecting, but are already loaded. The medium that has been brought into contact with the sheet roller can secure a sufficient stacking space.

  Here, the fixed elastic sheet and the idle elastic sheet may be formed on a part of the outer peripheral surface of the fixed roller and the idle roller, respectively, and the idle roller is rotated relative to the fixed roller. The fixed elastic sheet and the idle elastic sheet may be disposed over the entire outer peripheral surface of the rotating shaft. By using such a partial stack sheet roller, it is possible to obtain an effect that the sheet is arranged on the entire outer peripheral surface of the sheet roller when the medium is stacked.

  The phase recovery means can connect the idle roller and the rotating shaft, or connect the idle roller and the fixed roller. That is, the phase recovery means connects the idle roller that can freely rotate on the rotating shaft and the fixed roller that is fixed to the rotating shaft and rotates together with the rotating shaft, or connects the idle roller and the rotating shaft to idle the idle roller. The phase difference generated between the roller and the rotating shaft can be removed.

  At this time, the phase recovery means may comprise a spring clutch or a torsion spring that provides elastic force to the idle roller as the rotating shaft and the fixed roller rotate.

  Here, the spring clutch is formed at one end around the rotation shaft insertion portion wound around the rotation shaft and connected to the rotation shaft or the fixed roller. A fixed roller connecting portion and an idle roller connecting portion formed at the other end centering on the rotating shaft insertion portion and connected to the idle roller may be included.

  The fixed roller and the idle roller are formed with stoppers that limit the relative rotation range of the idle roller with respect to the fixed roller.

  The stoppers are protrusions formed on the fixed roller and the idle roller, respectively, and the protrusions form a relative rotation range of the idle roller while both ends formed along the rotation direction of the rotation shaft are in contact with each other. Can be limited. In this way, by forming a stopper at the coupling portion where the fixed roller and the idle roller mesh with each other, it is possible not only to prevent excessive rotation of the idle roller relative to the fixed roller but also to prevent the phase recovery means. When the phase difference is removed, the idle roller can be easily restored to the initial position.

  Further, the present invention is provided on one rotation shaft of a medium separating and accumulating unit for separating a medium from a medium accommodating unit and accumulating a medium transported to the medium accommodating unit in order to achieve the problems described in detail. A sheet roller, which is provided on the rotation shaft so as to rotate together with the rotation shaft, and has a fixed roller on which an outer peripheral surface is formed with a plurality of fixed elastic sheets, and is positioned on one side of the fixed roller A plurality of idle elastic sheets arranged on the outer peripheral surface so as to be spaced apart from each other, and an idle roller capable of rotating relative to the fixed roller as the rotary shaft rotates; The idle elastic sheet maintains the same phase as that of the fixed elastic sheet by the elastic force applied to the idle roller when the medium is separated. It is also possible to provide a sheet roller, characterized in that the phase difference between the fixed elastic sheet and the idle elastic sheet by a frictional force of the idle elastic sheet occurs.

  Here, the fixed elastic sheet and the idle elastic sheet are not in contact with the medium at the time of separating the medium, and the idle elastic sheet is in contact with one surface of the previously accumulated medium at the time of collecting the medium. It may be secured.

  The fixed elastic sheet and the idle elastic sheet are positioned so as to be arranged over the entire outer peripheral surface of the rotating shaft when the medium is accumulated, and when the medium accumulation is completed, the fixed elastic sheet and the idle elastic sheet are arranged on the rotating shaft. You may position so that it may be arrange | positioned over a part of outer peripheral surface. That is, the same function as the radial sheet roller in which the sheet is formed over the entire outer peripheral surface can be performed while using the partial stack sheet roller.

  When the medium accumulation is completed, the idle elastic sheet is rotated on the rotation shaft by the phase recovery means for connecting the idle roller and the rotation shaft, or connecting the idle roller and the fixed roller. The sheet and the idle elastic sheet have the same phase.

  On the other hand, the phase recovery means includes a rotating shaft inserting portion wound so that the rotating shaft is inserted, and a fixed roller connecting portion and an idle roller connecting portion respectively formed at both ends around the rotating shaft inserting portion. And a leg portion that connects the rotating shaft insertion portion, the fixed roller connecting portion, and the idle roller connecting portion, respectively.

  As described above, the present invention does not require a separate sheet roller at the time of separation, so that not only can the production cost be reduced, but also the transport path structure of the media separation and accumulation unit of the financial automation equipment can be simplified. Can do.

  In the present invention, the stacking quality of the medium can be sufficiently secured by arranging the sheets in a radial manner during the stacking while using the partial stack sheet roller, so that the stacking quality can be improved.

  Hereinafter, the configuration and operation according to embodiments of the present invention will be described in detail with reference to the accompanying drawings. The following description is one of the various aspects of the claimed invention and the following description forms part of the detailed description of the invention.

  However, in the description of the present invention, specific descriptions regarding known functions or configurations will be omitted for the purpose of clarifying the gist of the present invention.

  FIG. 1 is a side view schematically showing a configuration of a medium separating and accumulating unit of a financial automation apparatus according to an embodiment of the present invention.

  In the following, for convenience of explanation, an explanation will be given by exemplifying a financial automation device for withdrawal using a paper medium supply device according to an embodiment of the present invention.

  Referring to FIG. 1, the financial automation device according to an exemplary embodiment of the present invention separates a medium storage unit 110 from a medium stored in the medium storage unit 110 and a medium stored in the medium storage unit 110. A medium separating and accumulating unit 120 for accumulating in the medium, a sensor unit (not shown) for determining whether or not there are two paper media that have passed through the medium separating and accumulating unit 120, and a medium according to the inspection result of the sensor unit A control unit (not shown) for controlling the separation operation of the separation / stacking unit 120 and a medium transport unit (not shown) for transporting the paper media separated one by one are provided.

  Here, the medium may include a thin medium having a predetermined area, but is preferably a paper medium such as a banknote or a check.

  The financial automation device separates the medium storage unit 110 installed in the main frame (not shown) forming the outer shell and the paper medium N received in the medium storage unit 110 into individual sheets. A medium separating and accumulating unit 120 for accumulating media in the accommodating unit 110, and a paper accommodating unit 110 for conveying and accumulating the paper medium N separated by the medium separating and accumulating unit 120 to a withdrawal port (not shown). And a medium transporting section (not shown) for transporting.

  Here, the medium storage unit 110 includes a substantially hexahedral storage unit 110 in which a storage space is formed, and a push plate (which presses the paper medium N stored in the storage unit 110 toward the medium separation unit 120). (Not shown).

  On the other hand, the front upper end portion of the medium storage unit 110 is opened, and the paper medium N flows in or out through the opened portion. At this time, the paper media N must be separated one by one, and for this purpose, the media separation and accumulation unit 120 is installed near one side end of the medium storage unit 110.

  The medium separating and accumulating unit 120 includes a pickup roller 121 that picks up the paper medium N one by one from the medium storage unit 110, and a paper medium that is mounted adjacent to the pickup roller 121 and separated one by one by the pickup roller 121. A feed roller 122 that causes N to flow into the transport path, a gate roller (not shown) that is stopped while maintaining an overlapped state with the feed roller 122, and a pinch that causes the paper medium N to closely contact the feed roller 122 A roller (not shown) is included.

  At this time, the gate roller can prevent double-sheet separation of the paper medium N. For this purpose, a sheet roller 140 is provided on one side of the gate roller.

  The medium separating and accumulating unit 120 separates or accumulates the paper media N one by one toward the upper part of the medium accommodating unit 110, and is installed not separately from the medium accommodating unit 110 but from the medium accommodating unit 110. . As a result, the separation performance of the paper medium N can be improved, and the production cost of the financial automation equipment can be reduced. For reference, in the description of the present embodiment, the medium separating and accumulating unit 120 is externally mounted on the outside of the medium storing unit 110. However, the medium separating and accumulating unit 120 may be built in the medium storing unit 110 in some cases. Is possible.

  Here, the medium separating and accumulating unit 120 can separate or accumulate media in the vertical direction, or can separate or accumulate media in the horizontal direction, and separates the paper medium N toward the lower or upper portion of the medium storage unit 110. Or it can be integrated.

  FIG. 1 shows an example in which separation or accumulation is performed in the upward and horizontal directions of the medium storage unit 110.

  Further, by using a stepping motor as a driving source of the pickup roller 121, it is possible to effectively cope with the case where two sheets are separated.

  Here, the sheet roller 140 not only serves to draw the paper medium N that is nipped and conveyed between the medium conveyance belts (not shown) into the medium storage unit 110, but also to the medium storage unit 110. By pushing the accumulated paper medium N, it is possible to secure a collection space for the newly accumulated paper medium N.

  At this time, when the paper medium N is separated by the medium storage unit 110 and the withdrawal is performed, the sheet roller 140 does not come into contact with the paper medium N.

  Hereinafter, the sheet roller 140 in the case where the paper medium N is separated through the medium separating and accumulating unit 120 of the financial automation device according to the embodiment of the present invention will be described in detail with reference to the drawings.

  2 is a perspective view showing a rotating shaft and a sheet roller when the medium is separated by the medium separating and accumulating unit according to FIG. 1, and FIGS. 3a and 3b are a perspective view and an exploded view showing the sheet roller according to FIG. FIG. 4 is a side view showing a state of the sheet roller when the medium is separated by the medium separating and accumulating unit according to FIG.

  Referring to FIG. 2, the sheet roller 140 according to an embodiment of the present invention may be mounted on the same rotation shaft 150 as a gate roller (not shown). The sheet roller 140 may be provided on at least one side of the gate roller or at least one side end of the rotation shaft 150.

  Here, the sheet roller 140 is installed on the rotary shaft 150 so as to rotate together with the rotary shaft 150 provided with a gate roller (not shown), and a plurality of fixed elastic sheets 142 spaced apart are formed on the outer peripheral surface. The fixed roller 141 and a plurality of idle elastic sheets 147 which are installed on the rotation shaft 150 so as to be positioned on one side of the fixed roller 141 and are spaced apart from each other are formed on the outer peripheral surface, and the rotation shaft 150 rotates. The idle roller 146 capable of relative rotation with respect to the fixed roller 141, and the phase difference between the fixed roller 141 and the idle roller 146 caused by the relative rotation of the idle roller 146 with respect to the fixed roller 141 are removed or the phase difference is eliminated. Phase recovery means (not shown) for returning the idle roller 146 to the initial state may be included.

  By configuring the sheet roller 140 to include the fixed roller 141 and the idle roller 146 that rotate relative to each other as described above, the sheet roller 140 is prevented from coming into contact with the paper medium when the medium is dispensed or separated. In addition, not only the sheet roller 140 and the paper medium are brought into contact with each other at the time of stacking, but also the already loaded paper medium is pressed while being in contact with the sheet roller 140, because the paper medium is newly loaded in the medium storage unit 110. This space can be secured sufficiently.

  On the other hand, referring to FIG. 2, it can be seen that the fixed elastic sheet 142 and the idle elastic sheet 147 are located on the same side with a virtual vertical line passing through the rotation shaft 150 as the center. When the paper medium is withdrawn or separated, the paper medium is separated while passing through a portion where the fixed and idle elastic sheets 142 and 147 are not present, so that the paper medium and the fixed and idle elastic sheets 142 and 147 are not in contact with each other. In other words, it is possible to prevent the paper medium and the sheet roller 140 from contacting each other without the need to avoid the sheet roller 140 at the time of separation.

  The positions of the fixed roller 141 and the idle roller 146 may be changed from each other. That is, in FIG. 2, the fixed roller 141 is positioned on the center side of the rotating shaft 150 and the idle roller 146 is positioned on the outer side of the rotating shaft 150, but the opposite is also possible.

  Here, the fixed elastic sheet 142 and the idle elastic sheet 147 may be formed on a part of the outer peripheral surface of the fixed roller 141 and the idle roller 146, respectively. Referring to FIG. 2, the fixed elastic sheet 142 and the idle elastic sheet 147 are not formed so as to be disposed over the entire outer peripheral surface of the rotating shaft 150 in the initial state (that is, when separating the paper medium). The rotary shaft 150 is formed so as to be disposed only on a part of the outer peripheral surface. As described above, the paper medium is separated in a state where the fixed elastic sheet 142 and the idle elastic sheet 147 are only partially formed.

  Here, the fixed elastic sheet 142 and the idle elastic sheet 147 may be formed integrally with the body portion of the fixed roller 141 and the body portion of the idle roller 146, or may be formed separately.

  At this time, a recovery means fixing hole 151 for fixing the phase recovery means may be formed in the vicinity of the end of the rotating shaft 150 located outside the idle roller 146.

  3A and 3B show the sheet roller 140 in an initial state, that is, a state in which a paper medium is separated and dispensed by the medium storage unit 110. The fixed roller 141 and the idle roller 146 are attached to the rotating shaft 150 in a state where they are meshed with each other. At this time, it can be seen that a step structure is formed in a portion where the fixed roller 141 and the idle roller 146 mesh with each other. Such a step structure is for limiting the relative rotation range or phase difference of the idle roller 146 with respect to the fixed roller 141, and is the stoppers 143 and 148.

  The stoppers 143 and 148 are projecting structures or step structures formed on the fixed roller 141 and the idle roller 146, respectively. The stoppers 143 and 148 are formed while both end portions formed along the rotation direction of the rotating shaft 150 are in contact with each other. The relative rotation range of the idle roller 146 with respect to the fixed roller 141 can be limited.

  First, the stopper 143 formed on the fixed roller 141 protrudes toward the idle roller 146 at the body portion of the fixed roller 141. Locking contact surfaces 143a and 143b are respectively formed at both ends of the stopper 143, and a rotating contact surface 143c that rotates while contacting the body portion of the idle roller 146 is formed between the locking contact surfaces 143a and 143b.

  On the other hand, the stopper 148 of the idle roller 146 that meshes with the fixed roller 141 has the same shape as the stopper 143 of the fixed roller 141. That is, the stopper 148 of the idle roller 146 protrudes from the body portion of the idle roller 146 toward the fixed roller 141. Locking contact surfaces 148a and 148b are formed at both ends of the stopper 148, and a rotating contact surface (not shown) that rotates while contacting the body portion of the fixed roller 141 is formed between the locking contact surfaces 148a and 148b. Is done.

  If the fixed roller 141 and the idle roller 146 having such stoppers 143 and 148 are mounted on the rotary shaft 150, the rotation contact surface 143c of the stopper 143 of the fixed roller 141 comes into contact with the body portion of the idle roller 146, The rotational contact surface of the stopper 148 of the idle roller 146 is in contact with the body portion of the fixed roller 141. If the fixed roller 141 and the idle roller 146 rotate relative to each other in such a state, the rotation range of the idle roller 146 is determined by the contact of the locking contact surfaces (143a, 143b, 148a, 148b) of the stoppers 143, 148. Limited.

  Referring to FIG. 3a, in the initial state (that is, when the paper medium is separated), the locking contact surface 143a of the stopper 13 of the fixed roller 141 and the locking contact surface 148a of the stopper 148 of the idle roller 146 are in contact with each other. It is.

  In this way, by forming the stoppers 143 and 148 in the coupling portion where the fixed roller 141 and the idle roller 146 mesh with each other, it is possible to prevent the relative rotation of the idle roller 146 with respect to the fixed roller 141 from occurring excessively. Instead, the idle roller 146 can be easily restored to the initial state when the phase difference is removed by the phase recovery means 160 (see FIG. 6b).

  Meanwhile, a phase recovery unit 160 that connects the idle roller 146 and the rotating shaft 150 or connects the idle roller 146 and the fixed roller 141 may be provided. That is, the phase recovery means 160 connects the idle roller 146 that can freely rotate on the rotation shaft 150 and the fixed roller 141 that is fixed to the rotation shaft 150 and rotates together with the rotation shaft 150, The rotation shaft 150 can be connected to remove the phase difference generated between the idle roller 146 and the rotation shaft 150, or to restore the relative rotation of the idle roller 146.

  FIG. 3 b shows the sheet roller 140 provided with a phase recovery means 160 between the fixed roller 141 and the idle roller 146. The phase recovery means 160 can be configured by a spring clutch or a torsion spring that provides an elastic recovery force to the idle roller 146 as the rotating shaft 150 and the fixed roller 141 rotate. The detailed configuration of the phase recovery means 160 will be described later with reference to the drawings.

  If the rotating shaft 150 and the fixed roller 141 rotate counterclockwise in the state shown in FIG. 3B, the phase recovery means 160 is twisted to apply an elastic force to the idle roller 146.

  FIG. 4 shows the relative positions of the paper medium and the sheet roller 140 when the paper medium is separated. As shown in the drawing, when the paper medium N is separated, the fixed elastic sheet 142 and the idle elastic sheet 147 of the sheet roller 140 overlap each other or are substantially at the same position, so that the elastic sheets 142 and 147 do not contact the paper medium N. In this state, the rotating shaft 150 provided with the sheet roller 140 does not rotate. In this way, by forming the elastic sheets 142 and 147 only on a part of the outer peripheral surface of the sheet roller 140, it is not necessary to avoid the sheet roller 140 from interfering with or contacting the paper medium N when the paper medium N is separated.

  Hereinafter, the operation of the sheet roller 140 during paper medium accumulation will be described in detail with reference to the drawings.

  5 is a perspective view showing a rotating shaft and a sheet roller when the medium is collected by the medium separating and accumulating unit according to FIG. 1, and FIGS. 6a and 6b are a perspective view showing the sheet roller according to FIG. FIG. 7 is an exploded view, and FIG. 7 is a perspective view illustrating a state of the sheet roller when the medium is stacked by the medium separating and stacking unit according to FIG. 1.

  The sheet roller 140 shown in FIG. 5 is in a state in which the fixed roller 141 and the rotation shaft 150 of the sheet roller 140 shown in FIG. 2 are rotated counterclockwise (see the arrow in FIG. 5).

  The fixed roller 141 rotates together with the rotating shaft 150, but the idle roller 146 may not rotate because it is not fixed to the rotating shaft.

  At this time, when the rotating shaft 150 starts to rotate in the initial state, the fixed roller 141 and the idle roller 146 can rotate together. When the rotation shaft starts to rotate, the idle roller 146 can also rotate because the idle medium 146 does not come into contact with the paper medium loaded on the medium storage unit 110. If the rotation further proceeds and the elastic sheet 147 of the idle roller 146 comes into contact with the paper medium loaded in the medium storage unit 110, the idle roller 146 should not rotate any more due to the frictional force generated between them. There is also.

  That is, while the idle elastic sheet 147 of the idle roller 146 pushes the paper medium loaded in the medium storage unit 110 and does not rotate any more, the fixed roller 141 continues to rotate together with the rotating shaft 150, so that the idle roller 146 is fixed to the idle roller 146. A relative rotation or phase difference occurs between the roller 141 and the roller 141.

  In a state where the idle roller 146 rotates relative to the fixed roller 141, the fixed elastic sheet 142 and the idle elastic sheet 147 are disposed so as to be positioned over the entire outer peripheral surface of the rotating shaft 150. With such an operation, it is possible to obtain the effect that the elastic sheet is disposed on the entire outer peripheral surface of the sheet roller during medium accumulation while using the partially stacked sheet roller in which the elastic sheet is formed only on a part of the outer peripheral surface.

  Here, the relative rotation of the idle roller 146 with respect to the fixed roller 141 occurs further if the locking contact surface 143b of the stopper 143 of the fixed roller 141 and the locking contact surface 148b of the stopper 148 of the idle roller 146 contact each other. do not do.

  Referring to FIG. 6 a, a state where the locking contact surface 143 b of the stopper 143 of the fixed roller 141 is in contact with the stopper 148 of the idle roller 146 is shown. This state is between the fixed roller 141 and the idle roller 146. Relative rotation, that is, a state in which the phase difference is maximized.

  Referring to FIG. 6B, the recovery elastic force is generated while the form of the phase recovery unit 160 installed between the fixed roller 141 and the idle roller 146 is deformed in a state where the phase difference is generated. In this state, if the contact state between the elastic sheet 147 of the idle roller 146 and the paper medium N stacked on the medium storage unit 110 is released, the idle roller 146 is rotated to the initial state by the elastic force of the phase recovery means 160. Become. As described above, the phase difference or relative rotation between the idle roller 146 and the fixed roller 141 can be eliminated by the elastic force of the phase recovery means 160.

  FIG. 7 is a diagram illustrating a state where the received paper medium N is accumulated in the medium storage unit 110. As shown in the figure, when the paper medium N is accumulated, the idle roller 146 rotates relative to the fixed roller 141 to generate a phase difference therebetween, so that the fixed elastic sheet 142 and the idle elastic sheet 147 are evenly distributed radially. can do.

  In this state, the newly-added paper medium N is pulled by the fixed elastic sheet 142 located in the upper left half region and conveyed to the medium storage unit 110 side, and the paper medium N that has already been received in the medium storage unit 110. Is pressed against the idle elastic sheet 147 located in the left half load side region, and a frictional force is generated between the paper medium N and the idle elastic sheet 147, and the rotating shaft 150 is rotated by such a frictional force. Nevertheless, the idle roller 146 may not be able to rotate.

  As described above, by pressing the paper medium N stored in the medium storage unit 110 while the elastic sheets 142 and 147 are equally distributed radially when the paper medium N is stacked, a sufficient space for the newly stacked paper medium N is obtained. Can be secured in the medium storage unit 110.

  In other words, when the paper medium N is separated, the idle elastic sheet 147 maintains the same phase as the fixed elastic sheet 142 (see FIG. 4), and when the paper medium N is accumulated, the paper medium N previously accumulated in the medium storage unit 110 A phase difference occurs between the idle elastic sheet 147 and the fixed elastic sheet 142 due to the frictional force of the idle elastic sheet 147.

  Here, the fixed elastic sheet 142 and the idle elastic sheet 147 do not contact the paper medium when the paper medium N is separated, and the idle elastic sheet 147 is newly accumulated while being in contact with one surface of the previously accumulated paper medium when the medium is accumulated. A medium accumulation space can be secured.

  The fixed elastic sheet 142 and the idle elastic sheet 147 at the time of paper medium accumulation are positioned so as to be disposed over the entire outer peripheral surface of the rotating shaft 150. When the paper medium accumulation is completed, the idle roller 146 is moved to the initial state by the phase recovery means 160. Therefore, the fixed elastic sheet 142 and the idle elastic sheet 147 can be positioned so as to be disposed over a part of the outer peripheral surface of the rotating shaft 150.

  That is, when the paper medium accumulation is completed, the idle elastic sheet 147 rotates on the rotation shaft 150 by the phase recovery means 160 that connects the idle roller 146 and the rotation shaft 150 or connects the idle roller 146 and the fixed roller 141. The fixed elastic sheet 142 and the idle elastic sheet 147 may have the same phase.

  FIG. 8 is a perspective view showing the phase recovery means of the sheet roller according to FIGS. Referring to FIG. 8, in the phase recovery unit 160, a rotation shaft insertion portion 169 into which the rotation shaft 150 is inserted is formed at a substantially central portion, but the rotation shaft insertion portion 150 is used to generate a torsion. Preferably it is wound at least once.

  A fixed roller coupling portion 162 and an idle roller coupling portion 166 are formed at both ends around the rotation shaft insertion portion 169, and the rotation shaft insertion portion 169 and the coupling portions 162, 166 can be coupled by legs 161, 167, respectively. Here, the fixed roller connecting portion 162 can be connected to the fixed roller 141, but can also be connected to the rotating shaft 150.

  If the state shown in FIG. 8 is the initial state of the phase recovery means 160 (that is, corresponding to FIG. 2), if a phase difference occurs between the idle roller 146 and the fixed roller 141, the fixed roller connecting portion 162 Elastic force is generated in the phase recovery means 160 while the idle roller connecting portion 166 approaches each other.

  The phase recovery means 160 shown in FIG. 8 is merely an example, and is not necessarily limited thereto, and various types of elastic members such as a spring clutch or a torsion spring may be used.

  With such a configuration, the sheet roller can perform the same function as the sheet roller in which the sheet is formed radially over the entire outer peripheral surface while using the partial stack sheet roller.

  The sheet roller described so far includes a recycling box, and is a component of a financial automation device in which paper media such as banknotes or checks are deposited and withdrawn through a single deposit / withdrawal port such as a temporary stack unit and a customer service unit. Used.

  The preferred embodiment of the present invention has been described above by way of example, but the scope of the present invention is not limited to such a specific embodiment, and is appropriately within the scope of the claims. It can be changed.
