SUMMARY OF THE INVENTION

In general, in one aspect, a paper passageway delivers bills that have been picked from a bill supply container to a location at which the bills are to be dispensed, the paper passageway and the bill supply container are structurally coupled together at least temporarily to form an integrated bill dispensing structure, and at least one of the bill supply container and the paper passageway are functionally incomplete in the absence of the other.

Implementations may include one or more of the following features. The bill supply container lacks a wall to support bills, the wall being provided by the paper passageway in the integrated bill dispensing structure. Side walls of the bill supply container are coupled to the wall provided by the paper passageway.

Each of the side walls of the bill supply container is coupled to the passageway wall at an upper location and a lower location. The bill supply container is configured to enable access by a picker to bills stored in the supply container, and the paper passageway is configured to receive bills delivered from the picker. The bill supply container is generally box-shaped and includes an integral extension from the box to couple the bill supply container to the paper passageway. The integral extension extends under the picker and is attached to the paper passageway. Opposite sides of the integral extension are coupled to side walls of the picker when the picker is installed. An underside of a base of the bill supply container includes molded strengthening features that provide structural strength to the integrated bill dispensing structure. Control electronics are housed in the base of the bill supply container and supported by the strengthening features. The bill supply container includes molded feet for mounting the integrated bill dispensing structure. The bill supply container includes electrical terminals to which the picker mates. The bill supply container includes a plate to apply pressure to a stack of the bills that are in the container and ready for dispensing and a one-piece guide rail to guide the plate back and

® or 1/642 forth toward and away from the stack of bills, the guide rail piece forming a floor of the bill supply container. The one-piece guide rail is snapped at its ends to respective side walls of the bill supply container and provides structural strength for the side walls. The plate is biased toward the bill stack and the apparatus also includes a locking mechanism to hold the plate away from the bill stack for loading of bills. The locking mechanism comprises a rotating key formed of two plastic elements that mate through a hole in a front wall of the bill supply container.

In general, in another aspect, a paper passageway delivers bills that have been picked from a bill supply container to a location at which the bills are to be dispensed or a location at which the bills are to be rejected, a reject container holds rejected bills in a stack in which the bills are oriented vertically, and the bills are accessible to a user from an open top of the container.

Implementations may include one or more of the following features. The reject container comprises a single integral piece. The reject container comprises a vertically configured box open at the top to receive bills fed by gravity from a reject path of the paper passageway. The reject container comprises a rear wall sloped to direct bills fed by gravity into the reject container attached to the paper passageway. The reject container comprises an angled bottom floor to cause each of the bills fed by gravity into the reject container to be oriented vertically and in a position that causes each successive bill to be placed in front of the prior bill until the tray is full.

In general, in another aspect, a paper passageway to deliver bills that have been picked from a bill supply container to a location at which the bills are to be dispensed, the paper passageway and the bill supply container are coupled at least temporarily to form a structure, a picker is positioned within the structure to enable the picker to pick bills from the bill supply container and move them along a predetermined path for delivery to the paper passageway, and the

® picker is removable from the position within the structure by sliding the picker in a direction perpendicular to the predetermined path.

Implementations may include one or more of the following features. The picker includes an anti-backup roller requiring periodic maintenance. The picker is latched into and unlatched from the position using a single hand-operated knob.

Guide features aid the sliding of the picker.

In general, in another aspect, a bill dispensing structure including a bill supply container, a paper passageway to deliver bills that have been picked from a bill supply container to a location at which the bills are to be dispensed through a wall to a user, a reject tray to receive bills that are diverted from the paper passageway and are not dispensed through the wall, and a mounting mechanism to support the bill dispensing structure on the wall, the bill dispensing structure being self supporting and rigid without additional support.

Implementations may include one or more of the following features. The mounting mechanism comprises mounting elements near the top of a side of the bill dispensing structure that faces the wall. The mounting elements comprise pins each having an end connected to the bill dispensing structure and a free end projecting from the bill dispensing structure in a direction parallel to the wall.

The mounting mechanism comprises four pins any two of which are adequate to support the bill dispensing mechanism on the wall.

In general, in another aspect, a picker is removed from a position at which the picker can pick bills from a bill supply container and move them along a predetermined path for delivery to a paper passageway from which they are to be dispensed, the picker being removed by sliding it in a direction perpendicular to the predetermined path. Implementations may include one or more of the following features.

® shaft ends 51, 53, that mate with two pin locator holes 41, 43, on frame 226. A quarter-tum snap fastener 169 mounted on the other frame 224 rotates to hold the picker in place. No permanent fasteners are used.

The bottom 76 of the bill supply container, including the arm, bear a pattern of ridges 78 designed to provide rigidity and strength to the container. The pattern of ridges also provides an available space for mounting a circuit board 80 that is used to control the operations of the bill dispenser and its components. One end of the circuit board includes socket 82 into which a plug 84 on the picker fits when the picker is inserted into its installed position. The connection of the socket and plug provides power to a motor 86 on the picker.

The other end of the circuit board bears two sockets 88, 90 that are used for power and communication respectively. A channel 92 in the bottom of the am can carry a cable between a port 94 on the board and a double detect circuit and other sensors on the paper passageway.

Inside the bill supply container, a pressure plate 96 includes a flat surface 98 that bears against a stack of bills 100 (only a portion of which is shown), two ends 102, 104 that ride on supports 106, 108, two finger grips 110, 112, that enable a user to pull the plate back away from the stack for loading or reloading the stack, and a latching structure 114 that mates with a related grip 116 on a ) rotating lock 118 that is mounted on the front wall of the container.

The two supports 106, 108 are mounted through slots 120, 122, on opposite side walls of the container.

On each side of the container, beneath the supports 106, 108 are spring-loaded drive wheels 124, which are connected to the ends 102, 104 to pull the plate towards that stack of bills.

@® =

Also inside the bill supply container are two vertical guides 128, 130 and two horizontal guides 130, 134 that define a channel within which the stack of bills rides.

The rotating lock 118 is formed of two plastic pieces 140, 142 that mate and form an integrated lock when the two pieces are inserted in opposite directions through a mounting hole in the front wall of the container and are pressed together. Once mounted, the lock can be rotated so that the grip 116 can be mated to and unmated from the latching structure 114 in order to hold the plate and prevent it from springing back on the stack of bills or to release the plate, as desired. A finger 144 on the grip presses against a surface 114 of the plate in the locked position.

The container includes two feet 150, 152 that permit it to be securely mounted on a base, for example, a part of an ATM.

The picker has three drive wheels 154, 156, 158 that rotate to pick individual bills from the top of the stack and drive each of them downward and with assistance of additional drive wheels 155, 157, into the double detector (see arrow 159) where it can be picked up by the paper passageway. The drive wheels 154, 156, 158, are held on a shaft 160 that is rotationally mounted on both ends of the picker and is driven by a gear 162 on one end of the picker.

Gear 162 is driven by a gear train including gears 164, 166, and in turn driven by a worm gear 168 on a shaft of the motor. Drive wheels 155, 157 are driven by gear 166.

The arm of the container includes guiding surfaces 170, 172 and ribs 59 that correspond to surfaces and slots on the picker and enable the picker to be inserted and removed easily and with good alignment.

To insert the picker, the end 171 of the picker opposite the motor is inserted into the space between the bill supply container and the paper passageway with the

J LL guiding surfaces and tab of the picker mated with the corresponding guiding slots and ribs of the container am. The picker is slid into place. Two pins on the end of the picker fit into two corresponding holes of a side piece of the paper passageway. The electrical terminal 84 automatically makes connection with the circuit board beneath the bill supply container, as explained earlier. The picker is held in place using the quarter turn knob 169, figure 10. To remove the picker a reverse series of steps is used.

The picker is easily removed and replaced which makes maintenance and cleaning of its parts simple and easy. When installed, the picker is precisely aligned as required for reliable picking.

The reject tray 26 is an integral molded plastic unit that has an open top 181 and is easily accessible at any time to a person who has authority to maintain the bill dispenser or unload the reject bills. The reject tray is not a locked cassette.

Rather, bills may be unloaded at any time directly from the bill dispenser.

The reject tray has two parallel side walls 180, 182, spanned by a front wall 184 and a rear wall 186. The rear wall is generally flat and has a projection 188 away from the inside of the tray that provides finger room to reach behind a stack of bills when the stack is to be removed. The front wall has a cutout 190 to permit a user to reach down to retrieve a stack of bills and another finger projection 192 to make it easier to grasp the stack. The contours of the front and rear walls and the bottom 194 are arranged so that bills dropped by gravity from the reject path into the tray will automatically stack themselves into a vertically oriented stack of bills. When a bill 196 is delivered from the gentle curve of the paper passageway reject path, the bill follows a path 198. Driven by gravity downward and by inertia towards the front wall of the reject tray, the bill strikes the front wall at curved surface 200 and follows the curve downward. The leading edge of the bill strikes the bottom wall at point 212 and slides down to point 214. Eventually the upper edge of the bill falls over 216 to take its place on

® stack 218. Even if a given bill does not fall over to join the stack, the next bill or bills will feed themselves onto the front-wall side of the previously received bill and eventually the bills will fall over onto the stack.

The paper passageway 18 is defined within a bill delivery assembly 22. The bill supply container is bolted to the bill delivery assembly to form a strong rigid structure. Two bolts 220, 222, on each side of the bill supply container connect the container to two side frames 224, 226 of the bill delivery assembly. In addition, the end of the arm 54 of the bill supply container is bolted to the bottom of bill delivery assembly on a piece 228 that spans between the two side frames.

The picker is arranged to peel one bill at a time from the stack in the supply container and to deliver it to the paper passageway. The picker also reorients the bills from their vertical arrangement in the supply container to a horizontal orientation for delivery to the paper passageway. The picker is held in position, but can be removed and reinserted easily and quickly by sliding it in a direction15 that is perpendicular to a path along which bill moves from the supply container to the paper passageway.

A bill that has been delivered from the supply container to the paper passageway is driven upward along the paper passageway by four pairs of frictional rollers 230, 232, 234, 236 that are mounted on two parallel shafts 238, 240.

At the lower end of the paper passageway a curved surface 241 reorients the bill from horizontal to vertical for its trip up the paper passageway a direction of motion that is perpendicular to the direction in which the bill leaves the supply container.

At the upper end of the paper passageway, the traveling bill can either be diverted by a curved surface 250 into the reject tray or by a curved surface 256 to the dispensing location. Which way the bill travels depends on the position of

® a control vane 25 that can be rotated (about an axle) between two positions.

The vane is spring-biased to a default position that rejects bills into the reject tray and must be driven to the dispensing position. (The default routing is applied only to the first bill in the series after which the remaining bills in the series are routed by default to the dispensing location, unless one of those remaining bills is also determined to be flawed.)

A bill that is diverted to the dispensing location is driven out of the paper passageway by two additional pairs of frictional rollers 263, 264. A bill that is diverted to the reject tray is driven by two pairs of frictional rollers 258, 259.

The bottom end of the paper passageway supports a double-detect mechanism 270 that is used to determine, for example, when more than one bill has been withdrawn from the supply container at one time. lf so, the dispenser leaves the vane in the rejection position and the multiple bills are rejected into the reject tray. Otherwise, the vane is forced to the dispensing position and the single bill is dispensed to the customer.

The double-detect mechanism uses a Hall effect sensor to determine whether more than one bill has been withdrawn from the supply container by measuring the thickness of the bill and comparing it to a maximum thickness value.

Each of the frames 224, 226 of the bill dispenser includes holes 302, 304, 306, 308 at the top and bottom to receive mounting pins 310, 312, 314, 316. The pins may be used for purposes of mounting the dispenser to a wall 24 or door of, for example, an ATM. Each of the pins could be held by a hook-latch mechanism 318, 320, 322, 324 (in figure 1 only simple hooks are shown, but hook-latch mechanisms could be substituted).

Each of the hook-latch mechanisms could be operated independently. By releasing all four, the dispenser could be removed completely from wall 24. By releasing only the upper two mechanisms, the dispenser could pivot around the

- ol i» y bottom two pins with the top of the dispenser moving away from the wall to open a space for clearing jams in the paper passageway.

The frames including molded elements to assure that the dispenser can be supported on the pins without distortion or breaking of the frames or other elements of the dispenser being caused by the stress of the dispenser hanging from all four, or just two, of the pins.

In addition, when the dispenser is hung from the pins connected to the frames, the paper supply container is securely supported both to the fronts of the frames and the bottom of the paper passageway. A rib formation at the bottom of the paper supply container accepts a boss from the two frames, to stop movement of the container relative to the frames.

Thus, even though the bill supply container is not functional as a standalone container, unlike typical self-contained currency cassettes. Even though the picker is removable from the dispenser, when the container is mounted on the frames and the picker is installed its position, the dispenser behaves as a strong self supporting unit that resists distortion or breaking and can be hung on a wall 24 using supports that are mounted only on the frames.

Additional details conceming the paper passageway, the components that embody it, and the steps to assemble it, can be found in the published United

States patent application cited earlier which describes similar features of a paper passageway.

Because the dispenser is assembled from a small number of lightweight, easy to manipulate parts, assembly is fast and inexpensive, and the resulting dispenser is small, lightweight, and inexpensive. Maintenance can be done easily and inexpensively in case any part breaks or malfunctions.
