DETAILED DESCRIPTION
The following detailed description refers to the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the following description to refer to the same or similar elements. While embodiments and examples are described, modifications, adaptations, and other implementations are possible. For example, substitutions, additions, or modifications may be made to the elements and stages illustrated in the drawings, and the systems and methods described herein may be modified by substituting, reordering, or adding stages to the disclosed methods or elements to the disclosed systems. Accordingly, the following detailed description does not limit the disclosure. Instead, the proper scope of any invention disclosed herein is defined by the appended claims.
Self-service terminals can accept media objects of different sizes and conditions. In addition, the orientation of the media objects upon insertion into the self-service terminals can be inconsistent. To position the media objects into a uniform orientation, self-service terminals can use a deskew.
The deskew may include a drive member that can position a media object, such as a cheque or currency note, into a first position within the deskew. Once the media object is in the first position the deskew member can be used to position the media object into a second position. The second position can include an edge of the media object pressing against a fixed track of the deskew.
Movement of the media object along the fixed track may cause jams. The jams may be caused by tears in the media object or bunching of the media object. The media object may bunch due to older or more worn media objects being less stiff than newer or less worn media objects. In addition, transitions from one section of track to another can cause binding and other conditions that can lead to a jam. The binding and jams can also damage the media object. For example, during a transition from one track section to another, the media object may bind and tear.
To avoid jams, binding, and possible damage to the media object that can be caused by the media object moving along the fixed track, the deskew member can be reversed to reposition the now oriented media object a distance from the fixed track. Movement of the media object can be accomplished by reversing a motor that operates the deskew member. For example, a stepper motor can be reversed a fixed number of steps in order to move the media object a fixed distance from the fixed track.
FIG. 1 shows an example schematic of a self-service terminal 100 consistent with embodiments disclosed herein. The self-service terminal 100 may include a deskew 104 and a computing device 102. The deskew 104 may act as a media accepter/dispenser. During operation, the deskew 104 may accept media such as cheques and currency notes. As discussed herein, the deskew 104 may operate in conjunction with the computing device 102 to accept media and properly orient the media.
As shown in FIG. 1, the computing device 102 may include a processor 106 and a memory unit 108. The memory unit 108 may include a software module 110 and deskew data 112. While executing on the processor 106, the software module 110 and the deskew data 112 may perform processes for deskewing a media object, including, for example, one or more stages included in method 700 described below with respect to FIG. 7.
The self-service terminal 100 may also include a user interface 114. The user interface 114 can include any number of devices that allow a user to interface with the self-service terminal 100. Non-limiting examples of the user interface 114 can include a keypad, a microphone, a speaker, a display (touchscreen or otherwise), etc.
The self-service terminal 100 may also include a communications port 116. The communications port 116 may allow the self-service terminal 100 to communicate with information systems such as banking and other financial systems. Non-limiting examples of the communications port 116 can include, Ethernet cards (wireless or wired), Bluetooth® transmitters and receivers, near-field communications modules, etc.
The self-service terminal may also include an input/output (I/O) device 118. The I/O device 118 may allow the self-service terminal 100 to receive and output information. Non-limiting examples of the I/O device 118 can include, a camera (still or video), a printer, a scanner, etc.
FIGS. 2 and 3 show an example top view and a bottom view of the deskew 104. The deskew 104 can include a motor 202 operably connected to a drivetrain 204. The drivetrain 204 may be operably connected to a drive member 206 and a deskew member 208. As discussed below with respect FIGS. 4A-4D, the drive member 206 and the deskew member 208 may be used to position a media object within the deskew 104. The deskew member 208 and the drive member 206 can include one or more rollers, belts, or other forms of conveyance that can be used to move media through the deskew 104.
During operations, solenoids 210 and 212 may be used to raise and lower the drive member 206 and the deskew member 208. For example, to move the media object in a first direction, the solenoid 210 may lower the drive member 206 such that the drive member 206 contact a portion of the media object. To move the media object in a second direction the solenoid 210 may raise the drive member 206 and the solenoid 212 may lower the deskew member 208. A plurality of sensors 214 may be used to detect a position of the media object within the deskew 104. The plurality of sensors 214 may also be used to trigger operations such as engaging the drive member 206 and the deskew member 208 upon the media object being in given positions within the deskew 104.
FIGS. 4A-4D show example stages for deskewing a media object 400 consistent with embodiments disclosed herein. As shown in FIG. 4A, the media object 400 may enter a first portion of the deskew 104. The media object 400 may be inserted into the self-service terminal 100 and may pass into the deskew 104. Upon the media object 400 entering the deskew 104, the motor 202 may be engaged. For example, upon the media object 400 entering the deskew 104, the computing device 102 may transmit a signal to the motor 202 and engage the drive member 206. The drive member 206 may cause the media object 400 to advance into the deskew 104 to a first position.
As shown in FIG. 4B, upon the media object 400 reaching a first position within the deskew 104, the computing device 102 may receive signals from the plurality of sensors 214. Upon receiving the signals from the plurality of sensors 214, the computing device 102 may transmit a signal to the solenoids 210 and 212. The signal may cause the solenoids 210 and 212 to raise the drive member 206 and lower the deskew member 208.
As shown in FIG. 4C, the lowering of the deskew member 208 may cause the media object to transition into a second position. As shown in FIG. 5, the second position may include an edge 502 of the media object 400 resting against a track 504. The plurality of sensors 214 may detect when the media object 400 reaches the second position. The media object 400 in the second position may also be detected by feedback from the motor 202. For example, a strain placed on the motor 202 as the edge 502 of the media object 400 contacting the track 504 may be used to determine that the media object 400 is in the second position. For instance, a current draw increase by the motor 202 may indicate a strain placed on the motor 202 and thus, that the medial object 400 is in the second position.
Upon the media object 400 reaching the second position, the computing device 102 may transmit a signal to the motor 202. The signal may cause the motor 202 to reverse direction. Reversing the direction of the motor 202, the media object 400 may be moved a distance from the track 504 as shown in FIG. 6. In addition, a distance from the track 504, the media object 400 may be repositioned such that the edge 502 may parallel to a central axis of the deskew 104.
To reposition the media object 400 the motor 202 may be reversed for a preset time, such as for example, 0.05 seconds. In addition, the motor 202 may be a stepper motor and the stepper motor may be reversed for a preset number of steps, such as for example, 5 steps. In addition, to reposition the media object 400 additional solenoids and gears (not shown) may be used to reverse the direction of the deskew member 208 without reversing the direction of the motor 202.
As shown in FIG. 4D, upon the media object being reposition, a signal can be transmitted from the computing device 102 to the solenoids 210 and 212 to raise the deskew member 208 and lower the drive member 206. Upon lowering the drive member 206, the media object 400 can be ejected from the deskew 104.
It will be readily understood to those skilled in the art that various other changes in the details, material, and arrangements of the parts and method stages which have been described and illustrated in order to explain the nature of the inventive subject matter may be made without departing from the principles and scope of the inventive subject matter as expressed in the subjoined claims.
