Abstract
A depositor accommodating substantially thicker deposits than was possible with prior systems. A pair of plates each having a transport mechanism disposed as part thereof are coupled to a housing so as to abut each other, one above the other, in a rest position. A drive shaft for the transport mechanisms of the upper and lower plates are rotatably coupled to the housing and define an axis of rotation for each plate. The drive shaft for the top plate is disposed at an opposite end from the drive shaft of the bottom plate. A free end of each plate, the end opposite the drive shaft, is elastically coupled to the housing. This allows a substantially thicker deposit envelope to be accepted than was possible with prior systems.
Description




BACKGROUND OF THE INVENTION




(1) Field of the Invention




The invention relates to a mechanism for accepting customer deposits. More specifically, the invention relates to an automated depositor which can receive customer deposits of bundles of cash and/or checks of widely varying thicknesses and with reduced maintenance.




(2) Related Art




Automated depositors have been widely used in the banking industry for many years. Depositors are typically incorporated into automatic teller machines (ATMs), which provide other after hours banking services in addition to those provided by the depositor. Prior art depositors typically have a front gate which covers a deposit receiving opening or mouth of the depositor. The gate is typically driven by a solenoid which, in turn, is activated responsive to the deposit request by a customer. When the gate opens, it exposes through the opening an upper and lower plate, one of which typically includes a drive belt which frictionally engages the envelope to be deposited. The plate with drive belt is typically fixed within the depositor and does not move regardless of the thickness of the envelope, e.g., the deposit, being deposited. The other plate typically floats so as to maintain pressure between itself and the envelope and, therefore, the drive belt and the envelope. In such case, the floating plate is smooth so as to reduce the probability of a jam caused by the envelope sticking on the floating plate.




The maximum float of the floating plate has typically been about one quarter inch. Thus, these prior art depositors typically only accommodated deposit envelopes having a maximum thickness of about a quarter of an inch. This is a major shortcoming in view of the fact that the deposits of many customers, particularly businesses, are typically in the range of a quarter of an inch to one inch. Moreover, it is often not convenient for businesses to make their deposits during normal banking hours, nor is it convenient for them to have to split the deposits into multiple deposits of a quarter inch or less in order to complete the daily deposits outside of banking hours.




Prior art depositors also include printing devices such as a dot matrix printer or an inkjet printhead disposed within the depositor to allow printing on the envelope being deposited. This allows the bank to identify the deposit by an account number and conduct the transaction with minimal employee time. The printing is particularly important as physical deposit slips with account numbers are typically no longer included with the deposit. The print mechanisms suffer a number of problems. Residual ink often clogs the jetports of the inkjet printer and results in illegible printing. In some cases, the printer could not process the data or print it during the limited exposure as the envelope is driven under the printhead. Either case results in wasted employee time matching an account to the items being deposited.




In view of the foregoing, it would be desirable to develop a depositor that accommodates a broader range of deposit thicknesses within improved printing reliability.




BRIEF SUMMARY OF THE INVENTION




A depositor accommodating thick deposits is disclosed. A pair of plates each having a transport mechanism disposed as part thereof are coupled to a housing so as to abut each other, one above the other, in a rest position. A drive shaft for the transport mechanisms of the upper and lower plates are rotatably coupled to the housing and define an axis of rotation for each plate. The drive shaft for the top plate is disposed at an opposite end from the drive shaft of the bottom plate. A free end of each plate, the end opposite the drive shaft, is elastically coupled to the housing. This allows a substantially thicker deposit envelope to be accepted than was possible with prior systems.

DETAILED DESCRIPTION OF THE INVENTION





FIG. 1

is a right side view of a depositor of one embodiment of the invention with the right housing cover removed. A motor


1


is provided and coupled to housing


6


. The motor


1


drives timing belt


2


which in turn directly drives drive shaft


21


and pulley


3


. Timing belt


2


indirectly drives drive shaft


11


via pulley


3


and a gear assembly (not shown). The drive shafts


11


and


21


are rotatably coupled to housing


6


. This rotatable coupling can be accomplished using bushings or other similar known technique. Drive shafts


11


and


21


drive the transport mechanisms of upper plate


10


and lower plate


20


, respectively. One possible transport mechanism is one or more belts that surround drive shafts


11


and


21


wherein the belts are able to frictionally engage a depositable item. Spring


22


couples the lower plate


20


to the housing


6


at a connection point


80


. Similarly, spring


12


elastically couples the upper plate


10


to the housing


6


at a connection point


70


. A front gate


5


is coupled to the housing


6


and covers a mouth of the depositor when the depositor is installed in, for example, an ATM assembly.





FIG. 2

is a left side view of depositor

FIG. 1

with the left housing cover removed. Micromotor


8


is coupled to a housing


6


and drives linkage


9


to open gate


5


responsive to initiation of a deposit request. The micromotor


8


improves control and response over the prior art solenoid opening techniques. Gear assembly


7


allows motor


1


to drive drive shaft


11


such that drive belts (not shown) on plates


10


and


20


drive in the same direction. One such gear assembly includes a gear, a bearing and a shaft.





FIG. 3

is a top plan view of upper plate


10


in one embodiment of the invention. Longitudinal members


14


support drive shaft


11


and a plurality of follower shafts


17


. Two long drive belts


13


are disposed on pulleys


18


of opposing sides of the longitudinal members


14


. A pair of short belts


15


and


16


are disposed between longitudinal members


14


and coupled to the drive and follower shafts by pulleys


18


. A space is provided between front short belt


15


and rear short belt


16


in which print mechanism


19


is disposed. Anti-fishing hooks


32


are coupled to drive shaft


11


using a torsion spring


36


. A first envelope sensor


31


is provided adjacent to short belt


15


, while a second envelope sensor


33


is provided adjacent to short belt


16


. The envelope sensors


31


,


33


indicate when the deposit envelope has passed thereunder such that the gate


5


may be closed or a deposit accepted notification sent to the customer. Short belt


16


is offset, e.g., not co-linear with short belt


15


. This allows accommodation of sensor


33


, as well as clearing the print path such that no contact exists between the tray


10


and the print on the envelope created by print mechanism


19


. It is important to minimize or eliminate contact with the printed surface to allow the ink the opportunity to dry without smearing.





FIG. 4

is a sectional side view of the top plate of FIG.


3


. Print mechanism


19


has printhead


34


disposed so as to be a predetermined distance from an envelope transported by the various drive belts, including short belts


15


and


16


. This distance is maintained because the printhead floats with the plate. Upper plate


10


can pivot about an axis defined by drive shaft


11


, but is restrained in a rest position by springs


12


(shown in FIG.


1


). Thus, opposing end


50


can move in an upward arc above that pivot point, but the force exerted by springs


12


increases with displacement in accordance with Hooke's law. One or more stops (not shown) may be provided to ensure pivoting does not occur outside a maximum desired range. The pivoting of upper plate


10


and corresponding lower plate


20


occurs as a result of wedge action of a deposit envelope (described below). Accordingly, the springs


12


and


22


should be selected with sufficiently low spring constraints that within an established acceptable range, the resulting friction between plate


10


and plate


20


and the envelope will not over tax the motor


1


or result in a jam. The torsion spring


36


(as shown in

FIG. 3

) which the anti-fishing hook


32


is coupled to drive shaft


11


acts against the floor


37


of the plate


10


.





FIG. 5

is a plan view of the lower plate of one embodiment of the invention. Lower plate


20


has several structures corresponding to those found in the top plate. Specifically, lower plate


20


has a drive shaft


21


which drives two long drive belts


23


and two short drive belts


25


and


26


. The belts are supported by pulleys coupled to drive shaft


21


and follower shafts


27


. Significantly, drive shaft


21


is in the lower plate, the rear most shaft where the location of the front gate is defined to be the front. Similar to upper plate


10


, lower plate


20


pivots about an axis defined by its drive shaft


21


. Notably, this means that the front side of the lower plate


20


pivots, while the rear side of upper plate


10


pivots. Having effectively two floating plates, greater widths of deposit envelopes can be accommodated. In a preferred embodiment, the float of the upper plate


10


and lower plate


20


relative to each other allows deposit envelopes of up to one inch thickness to be deposited.




Lower plate


20


also includes a maintenance station


29


positioned so as to reside in a predetermined relation to the print mechanism


19


of the upper plate. The maintenance station


29


(described more fully with reference to

FIGS. 6



a


and


6




b


below) is positioned between short belt


25


and short belt


26


of lower plate


20


. The maintenance station is driven by a micromotor


35


coupled to the lower plate.





FIG. 6



a


shows a maintenance station


29


in a capping, or inactive, position. A cam


45


is driven by the micromotor


35


to cause the wiper


41


and capping cup


42


to move through a predetermined arc. The wiper


41


clears residual ink from the printhead when it is driven over the printhead


33


in preparation for printing and following completion of a print. These periodic wipings of the printhead


33


reduce the probability of print malfunctions due to clogs of the inkjets. Additionally, the capping cup


42


which is disposed so as to cap the printhead when no deposit is occurring, decreases the air exposure of the printhead


33


and thereby makes it less likely for the printhead


33


to dry up. A spring


43


applies pressure on the lower side of the capping cup holding it in place. A stop


44


is provided to prevent the overrotation of the wiper capping cup assembly.

FIG. 6



b


shows the maintenance station


29


in the printing (deposit accepting) position. In this position, the micromotor


35


has rotated the capping cup


42


90° such that it does not prevent passage of an incoming envelope. When the sensor


33


detects the envelope has passed, e.g., the deposit is accepted, the micromotor


35


rotates the capping cup


42


back into the capping position.





FIG. 7

is a sectional right side view of the depositor of one embodiment of the invention. As previously discussed, front gate


5


is opened responsive to a deposit request. Opening of gate


5


exposes mouth


70


into which a deposit envelope may be inserted. At the time the gate


5


opens, the drive belts


13


and


23


, as well as a short drive belt (not shown), will already be being driven by the motor by drive shafts


11


and


21


, respectively. The belts will, therefore, frictionally engage an inserted envelope drawing it into the depositor. The envelope will then serve as a wedge causing each plate to rotate about its axis of rotation along its respective drive shaft


11


or


21


. A maximum rotation is constrained by stops


51


for the upper plate


10


, and


61


for the lower plate


20


. Notably, each plate rotates independently of the other plate. The displacement of each plate is related to the location of the envelope relative to the axis of rotation. Once the sensor


31


detects that the envelope is completely inside, the front gate


5


can be driven closed. The drive belts


13


,


15


,


16


,


23


,


25


, and


26


will drive the envelope under the printhead


33


which will print a string of information on the envelope identifying the account and amount of the deposit. The envelope will then proceed across the plates and fall under the influence of gravity into a bin (not shown), thus, concluding the deposit.
