Abstract

A device for dispensing labels of value comprises a lockable housing for containing a roll of transport medium having a plurality of labels releasably adhered thereto successively along its length. The housing has a slot through which the transport medium can be discharged from the housing, and pinch rollers for engaging the medium outside the housing adjacent to the slot and, upon actuation, for drawing the medium through the slot. Upon command the pinch rollers are actuated to draw only sufficient medium through the slot to expose a single label for removal from the medium. The pinch rollers engage the medium with sufficient frictional force to rupture the medium if an attempt is made to manually pull the transport medium out of the slot when the rollers are not actuated.

Claims

1. A device for dispensing laminar items, comprising:

a secure housing for containing an elongated flexible transport medium having a plurality of laminar items releasably adhered thereto successively along its length;

a slot through which the transport medium can be discharged from the housing in its direction of elongation;

a timer controlled drive means comprising a pair of pinch rollers for engaging the medium adjacent to the slot and, upon actuation, for driving a repeatable amount of the medium through the slot;

control means operable upon command for actuating the drive means to drive only sufficient medium through the slot to expose a predetermined number of laminar items for removal from the medium;

self-locking means for retaining the transport medium against forced manual movement when the drive means is not actuated such that the medium will rupture if an attempt is made to manually pull the medium out of the slot;

the pinch rollers pressing on the medium with a sufficient frictional force to rupture the medium and laminar items in response to an attempt to manually pull the medium out of the slot;

a scanning device; and

the laminar items each including a machine detectable feature, the dispensing device halting each successive laminar item at a position not readable by the scanning device prior to receipt of a command to advance the transport medium.

2. A device as claimed in claim 1, wherein the retaining means comprises the drive means itself.

3. A device as claimed in claim 2, wherein the self-locking means includes a self-locking coupling.

4. A device as claimed in claim 1, wherein the pair of pinch rollers bear on opposite sides of the medium respectively, the drive means being actuated by rotating at least one of the rollers.

5. A device as claimed in claim 1, wherein the drive means engages the medium outside the housing and draws the medium through the slot.

6. A device as claimed in claim 1, wherein the spent medium is wound on a take-up spool which maintains a tension in the medium, and wherein the medium is subject to an abrupt change of direction along its path from the slot to the take-up spool, the laminar item being sufficiently stiff in relation to the strength of its adhesion to the medium that the laminar item automatically detaches from the medium where the latter changes direction.

7. A device as claimed in claim 1, wherein after each laminar item is dispensed the medium comes to rest with the next laminar item engaged by the drive means.

8. A device as claimed in claim 7, wherein the command is operative to actuate the drive means to advance the medium until the feature is first detected by the scanner and then to continue actuation of the drive means for a period sufficient to release the laminar item from the drive means but less than that required to move the medium an amount equal to the pitch of the laminar items along the medium.

9. A device as claimed in claim 8, wherein the machine detectable feature is a machine-readable code unique to each laminar item.

10. A device as claimed in claim 1, wherein the predetermined number of laminar item(s) is one.

11. A device as claimed in claim 10, wherein the laminar items are software Certificates of Authenticity labels.

12. A system for dispensing software authorization labels for personal computers (PCs) containing pre-loaded software, each label and each PC bearing a unique machine-readable ID, the system comprising:

a plurality of label dispensing devices each for containing a respective stock of software authorization labels releasably adhered to a transport medium relating to a different item of software;

first means for reading the unique ID on each PC;

means for determining, from a stored record correlating software items with PC ID, which software items are loaded, or are to be loaded, onto each PC;

timer controlled means responsive to each said determining for automatically actuating those devices corresponding to the determining of software items to repeatedly dispense a single label each;

means comprising a pair of pinch rollers, controlled to resist forced manual movement by a self-locking coupling, for engaging the medium adjacent to a slot and, upon actuation, during the medium through the slot;

the pinch rollers pressing on the medium with a sufficient frictional force to rupture the medium and the labels in response to an attempt to manually pull the medium out of the slot;

second means for reading the ID on each label; and

the dispensing devices halting each successive label at a position not readable by the second means for reading the ID prior to receipt of a command to advance the next successive label.

13. A system as claimed in claim 12, wherein the system further includes means for storing the codes read by the reader in correlation with the respective PC IDs.

14. A system as claimed in claim 13, wherein each device comprises a housing for containing said stock of labels, said stock of labels being releasably adhered successively along the length of the elongated flexible transport medium, and the pinch rollers driving said transport medium out of a slot in the housing to dispense said labels, and wherein said second means for reading the ID is adapted to scan the medium transversely of its direction of movement, and upon receipt of the command, the drive means is adapted to advance the medium until the machine readable code of a label is first detected by the second means for reading the ID and then to continue actuation of the pinch rollers for a predetermined period sufficient to release the label for removal from the transport medium.

15. A method for dispensing software authorization labels for personal computers (PCs) containing pre-loaded software, each label and each PC bearing a unique machine-readable ID, the method comprising:

providing a plurality of label dispensing devices each containing a respective stock of software authorization labels releasably adhered to a transport medium relating to a different item of software;

reading the unique ID on each PC by a first reading means;

determining, from a stored record correlating software items with PC ID, which software items are loaded, or are to be loaded, onto each PC;

responsive to each said determining, automatically actuating by a timer control device, those devices corresponding to the said determining of software items to repeatedly dispense a single label each;

providing a pair of pinch rollers controlled to resist forced manual movement by a self-locking device for engaging the medium adjacent to a slot and, upon activation, driving the medium through the slot;

the pinch rollers pressing on the medium with a sufficient frictional force to rupture the medium and the labels in response to an attempt to manually pull the medium out of the slot;

reading the ID on each label by a second reading means; and

halting each successive label at a position not readable by the second reading means prior to receipt of a command to advance the next successive label.

16. A device for dispensing labels of value comprising:

a secure housing including a lockable cabinet containing an elongated supply of transport medium having a plurality of labels releasably adhered thereto successively along its length;

the housing including an opening through which the transport medium can be discharged;

means separate from the lockable cabinet and actuatable, under timer control, for engaging the medium and drawing only sufficient medium out of the housing to repeatedly expose a single label for removal from the medium, the means for engaging applying a sufficient functional force to rupture the medium in response to an attempt to manually pull the medium through the opening when the means for engaging is not actuated, and the means for engaging being controlled to resist forced manual movement by a self-locking device;

a scanning device; and

the labels each including a machine detectable feature, the means for engaging and drawing, halting each successive label at a position not readable by the scanning device prior to receipt of a command to advance the transport medium.
