Description:
FIELD OF THE INVENTION 
     The present invention relates to a method and apparatus for temporarily storing at least one item of media at a storage location. In particular, but not exclusively, the present invention relates to the temporary storage of currency notes on a rotating support structure in a self-service terminal or teller assist unit or cash recycler unit or the like. 
     BACKGROUND TO THE INVENTION 
     As the bank branch becomes a primary delivery channel for financial institutions, there is a constant need to improve operational efficiency and provide users with an improved quality of service. Most financial institutions have in the past had a defined system in place determining how currency notes were physically handled in a branch. Typically, there has been a secure vault where bulk currency notes are stored and these are distributed after multiple counts to tellers who can then perform necessary cash transactions with customers. Likewise, when cash has been received from customers, this has been counted many times and eventually returned as incoming cash to a vault. It has thus not been uncommon for currency notes to be counted by hand many times on a journey through a branch. Such cash handling procedures have decreased employee efficiencies and increased customer wait times. There has thus been a need to reduce exposed currency notes in a branch. 
     As technology has improved, attempts have been made to automate certain aspects of the currency note handling process. Such technology allows for remote note imaging or check imaging, signature capture and other such verification steps. The development of such technology has led to the introduction of media depositories used in automated teller machines (ATMs) and other such self-service terminals. Media depositories are used to receive media items from a customer. One common type of media depository is a sheet media depository for receiving items of media in sheet form. For example, such items of media can be currency notes, checks, tickets, gyros or the like. Some sheet depositories are capable of receiving a bunch of sheet items of media in a loading area and then picking individual sheets from a bunch so that each sheet can then be identified and validated individually prior to storage of a validated sheet within a depository or returned to a customer. 
     Another type of automated unit is the currency recycler. In such devices, customers may deposit items of media such as currency notes, checks, vouchers or the like, and these are processed separately one-by-one and stored in various storage modules within a terminal. For example, a storage unit can be an escrow storage unit in which, instead of being deposited directly into a storage module, once counted and verified, currency notes or checks input by a user are held temporarily until a teller negotiating with a user completes a transaction. If a customer decides to cancel a transaction or asks for the items to be recounted, the original deposited bank currency notes can be returned. This function allows any disputes to be resolved promptly. The temporarily stored items are held in a roll storage module (RSM) in the escrow module. 
     Cash recyclers and other such units also include one or more roll storage modules (RSMs). Such RSMs are provided for each of the possible currency notes or checks or other such vouchers which may be presented at a recycler unit. For example, an RSM dedicated to a £10 note will be provided as well as an RSM dedicated to a £20 note as well as an RSM dedicated to a £50 note or the like. 
     When a customer presents a bunch of items, these do not need to be manually counted by a teller, but are instead fed into an input slot on the recycler unit. Each presented item is counted and verified within a recycler and once it has been decided to make a permanent deposit of the presented items, the items are separated and stored in a respective RSM. For example, all £20 notes presented in a bunch are stored in the £20 RSM etc. 
     A cash recycler thus helps automate acceptance, authentication and validation of currency notes. Another advantage of such units is that the deposited items which are stored in respective RSMs can subsequently be dispensed when another user attends at a teller and requests currency notes. A cash recycler thus enables previously deposited currency notes to be instantly available for dispensing to customers. 
     Cash recyclers also help reduce transaction times and time taken for start and end-of-day cash balancing. Average wait times for customers can thus be reduced and overall branch security is improved. 
     It is understood that there are other self-service terminals and other item storage devices where sheet items of media are stored on a semi-permanent basis for subsequent dispensation of the stored items to a user requesting them. On many occasions the rolled storage units utilized can store items for many hundreds, if not thousands, of hours in a curved state. This is because such storage units typically utilize a storage drum having a substantially cylindrical cross-section. Currency notes or checks or the like are stored by being wrapped around the drum and kept in place and duly located by one or more tape windings which are wound around the drum. A problem with such storage mechanisms is that when the items are dispensed, because they may have been stored for some time, they may retain part of the curved shape generated by being wrapped on a cylindrical drum. This effect can be worsened if the stored item was already badly curved prior to being stored. Such curled items of media have a tendency to increase a risk of jams occurring within a storage unit. Also, within the transport system utilized to move items of media around in a self-service terminal or the like, the risk of such jams is increased with curled or curved items.

     DESCRIPTION OF EMBODIMENTS 
     In the drawings like reference numerals refer to like parts. 
       FIG. 1  illustrates a teller assist unit  100  according to an embodiment of the present invention. It will be understood that certain embodiments of the present invention are not restricted to storage units within a teller assist unit but optionally may be used in automated teller machines (ATMs), cash recyclers, vending machines or the like wherever sheet items of media such as currency notes, checks, vouchers, pages or the like are to be stored and/or deposited. The teller assist unit  100  includes a secure housing  101  which includes a top wall  102  and floor standing wall  103 , together with a back wall  104  and a front fascia wall  105 . The front fascia includes a bill, entry/exit slot  106  at which a user can present a bunch of currency notes or checks or single currency notes or checks or other such items of media for deposit. The bill entry/exit slot  106  is also the outlet slot whereby items of media such as currency notes and/or checks are returned or are dispensed to a user dependent upon a user requirement. In the instance of a teller assist unit, the user is a teller of a bank branch or other such authorized user who acts as an interface with a bank customer. Currency notes or checks deposited are validated by a bill validator  107 , as will be understood by those skilled in the art. A bill transport path  108  which includes one or more rollers and/or endless belts is used to locate items of media one-by-one at a desired roll storage module  120 . 
     In addition to handling deposits the teller assist unit can be utiliutilizedispense currency notes which are stored in the roll storage modules. For example, if a teller requires £ 120  worth of currency notes, this information may be input at a user interface (not shown) on the front fascia  105  of the teller assist unit and then a central processing unit (not shown) initiates selection of currency notes from one or more roll storage modules. For example, to dispense £ 120 , the roll storage module (RSM) which holds £ 20  notes may be placed in a dispense mode of operation in which six previously stored £ 20  notes are dispensed from the RSM onto the bill transport path  108 . A bill return path module  125  is utilized to locate dispensing items from the bill transport path  108  to the exit slot  106 . It will be understood that rather than dispensing six £20 notes from a single RSM, the teller assist unit may be selectively operated to dispense two £50 notes from a £50 note RSM and two £10 notes from a £10 note RSM. Other combinations are of course possible. 
       FIG. 2  illustrates parts of an RSM  120 . Each RSM includes a secure box formed from a back plate  200  which is spaced apart from, and substantially parallel with, a front wall  201  (not shown). The front and back walls are closed by opposed end walls and top and bottom walls (also not shown). 
     Multiple shafts  205  extend between the front and back plates. Eight such shafts are shown in  FIG. 2 , although the specific number will be determined by the particular layout in a particular RSM. Each shaft  205  extends from a first end  206  thereof, which is secured to the back plate  200  to a second end  207  thereof, which is secured to the front plate (not shown). The shafts are fixed in place and carry a rotatable sleeve  210  or a driven reel  211   a ,  211   b . Each reel  211  includes a cylindrical body having a disc at each end thereof. Each reel is thus like a cotton reel-shaped body. A resilient tape is wound around the reels and the shafts. 
     Each RSM also includes a rotatable item support  250  which rotates about a longitudinal axis defined by a support shaft  255 . The drive shaft  255  is driven by a drive system which may optionally also drive the rotation of the reels  211   a ,  211   b . As shown in  FIG. 2 , according to a first embodiment of the present invention, the rotatable item support has a substantially rounded rectangular cross-section and extends along a longitudinal axis. A top surface  260  of the support is substantially planar and smooth and flat. This area provides a resting surface on which tape and/or currency notes may be supported in a flat configuration. The cross-sectional area of each planar support region is sized so as to be at least as large as a largest currency note or check or the like, which is predicted to be deposited and stored in the RSM. Aptly, each support region has a planar area of about around 105 cm 2  or more or less. Aptly, the support region has a planar area of about around 135 cm 2 . Aptly, each support region has a planar area of about around 155 cm 2 . As illustrated in  FIG. 2 , the support member shown has a further planar support region  265  on the lower surface of the support member  250 . The planar support regions are joined together by curved, smooth surfaces at the outer surface of the support member. 
     As illustrated in  FIG. 2 , each RSM includes an inlet slot  270  at which items of media transported by the bill transport system  108  are periodically presented one-by-one. This slit  270  is also used as an outlet slit whereby items of media previously stored on the support member may be unwrapped and dispensed through the exit slit  270  to the bill transport system  108  and the bill return path  125  for exit via exit slot  106  to a teller. 
     When a teller presents one or more currency notes at a bill entry slot  106  of the teller assist unit, these are transported one-by-one subsequent to bill validation via the bill transport system  108  and presented one-by-one at the inlet slit  270 . The storage support  250  is rotated in an anti-clockwise direction by a drive motor. Simultaneously, the drive motor system drives the reels of tape  211   a ,  211   b . In a deposit mode of operation the item support  250  is rotated more quickly than the rotation of the tape reels. This keeps each tape relatively taut as incoming items of media are wrapped around the item support. 
     In the embodiment shown in  FIG. 2 , two tapes are provided. One tape  260  is secured at a first end to the item support and is wrapped there around and extends across the pulley system to the upper reel  211   a . The further tape  261  is also attached at a first end thereof to the item support and then extends to the second lower reel  211   b . It will be appreciated that instead of utilizing two separate tapes, one long tape could be utilized which is fixed at a central position to the item support. 
     Incoming items of media are located between opposed upper and lower surfaces of the two tapes at an incoming region  280 . The two tapes at this region co-operate so that an incoming item of media is sandwiched there between. Rotary motion of the support winds the two tapes together with an item of media located there between onto the support member. The rotation of the support and the tapes is timed together with the presentation point of an item of media so that the item of media, such as a currency note, is stored wholly on a single flat surface of a planar support region of the item support. As the item support rotates further, items of media are deposited one-by-one on consecutive planar support regions. The net effect is that after a period of time, multiple currency notes are stored with intervening tape windings on each of the two planar support surfaces of the item support. 
     In a dispense mode of operation, currency notes previously stored on the item support must be removed and thereafter transferred to a bill exit slot  106  on the teller assist unit. Depending upon a number of currency notes which are needed, the upper reel  211   a  and lower reel  211   b  are driven so as to pull the tapes (and the currency notes stored therewith) off the also rotating item support. In the dispense mode of operation the item support shown in  FIG. 2  is driven in a clockwise direction. One-by-one currency notes which are bound together between the opposed tape sections are carried with the tape off the item support to the region  280  where the two tapes are closely juxtaposed and thereafter ejected through the exit slot  270 . 
     Because the currency notes and tape are stored on planar, smooth, flat surfaces, there is no inclination for the currency notes to acquire a curved shape despite, perhaps, being stored for many hundreds or thousands of hours on a support surface. 
     There will of course be a limit to the number of items of media which can be stored on any single item support. This will in many respects be determined by the length of tape available and wrapped around each of the upper and lower reels  211 . At least one of the reels (shown in the upper tape section of  FIG. 2 ) includes a marking line  295  which is carried on the tape. A detector (not shown) continually monitors for identification of this line or other such indicator which indicates that the reel is becoming empty and thus that a maximum storage capacity has almost been reached. 
       FIG. 3  illustrates an alternative embodiment of the present invention, in which the item support  350  is substantially triangular in cross-section. As such, the item support includes three planar surfaces, each of which is substantially smooth and flat and which is sized so as to wholly support a currency note that is to be stored in that particular RSM. As illustrated in  FIG. 3 , the item support includes three spaced apart substantially planar walls  351  which are secured to a central sleeve  352  by respective connecting plates  353 . The smooth, flat walls  351  are connected together by curved regions  354  to prevent the tapes which are wrapped around the item support from being abraded. As the central shaft  255  rotates, the item support rotates. The item support rotation is driven in a deposit mode of operation slightly more quickly than the speed of rotation of the storage reels. In a dispense mode of operation, the reels are rotated slightly more quickly than the speed of rotation of the item support. This maintains the tapes in a taut state at all times so that items of media can be duly deposited or dispensed or dispensed as appropriate. 
       FIG. 4  illustrates an alternative item support  450 , according to another embodiment of the present invention, which includes six substantially flat surfaces  460 , spaced apart substantially circumferentially around a central drive shaft  255 . Other parts similar to those shown in  FIGS. 2 and 3  are not illustrated in  FIG. 4  for convenience. 
     It will be understood that an item support may have one, two or more planar surfaces. The number of support surfaces is only limited by the practical size of a storage module and the fact that each planar support region must be large enough to support a whole item. 
     It will be appreciated that certain embodiments of the present invention are not restricted to the location of a single item of media on a single planar storage surface. For example, as shown in  FIG. 4 , when planar regions are adjacent and not angled too much with respect to one another, a single item of media could be bent in one or possibly two locations and stored in a substantially flat manner on multiple adjacent planar support surfaces. This would introduce a possible risk of creasing where an item is held across a joint between adjacent planar regions but would nevertheless provide an improvement upon current systems which produce curved items of media.
