     Referring to the drawings, a ticket issuing device comprises a box-like housing structure including a bed plate 1 constituting part of an upper housing section 2 connected by means of hinges 2a to a lower housing section (not shown). 
     The ticket issuing machine incorporates a computer-controlled electronic circuit (not shown) housed within the lower housing section for operation, according to a predetermined sequence, of ticket processing modules mounted on bed plate 1. 
     The ticket issuing device operates using ticket roll stock web material 3 supported for rotation about the axis of the roll 3 on arms 4 which include tubular segments 4a rotatable about the axes of the arms. The continuous web 5 extends from the roll 3 to a guillotine module 10 incorporating a base plate 11 with guillotine roll stock haul-off and web guide components mounted thereon. The guillotine 12 is equipped with a drive motor 13 while the roll stock haul-off means,constituted by driven roller 14 and passive roller 15, has a motor 16 connected to the driven roller by means of a toothed belt (not shown) located beneath bed plate 1. 
     The web 5 passes between the two sides of a sensor 17 over passive guide roller 18 equipped with a pivoted web guide 19 lightly pressed against the web 5 or guide roller 18 by means of compression spring 20. 
     The web 5 carries a longitudinally extending magnetic strip and is fed by the haul-off rollers 14, 15 to a magnetic encoder module 30. In order to monitor the quantity of available roll stock, a sensor 6 is provided beneath the roll 3 and this sensor provides a continuous reading of the reservoir of available ticket web material, The sensor 17 detects the end of the available ticket web material and operates to switch off the ticket issuing device on detection of the end of the web. 
     The magnetic encoder module 30 incorporates a base plate 31 on which upper and lower carrier plates 32, spaced apart by means of support posts 33, are mounted. The carrier plates 32 have inwardly facing vertically opposed longitudinal primary grooves 34 together defining a primary guide track for the web 5. The spacing of the plates 32 is such that the web is received edge-wise therebetween with its longitudinal edges trapped in grooves 34. 
     The magnetic ticket encoder module 30 also incorporates a ticket drive belt 35 which extends around pulleys 36 to 40, the pulley 36 being driven by a motor located beneath the bed plate 1 while pulleys 37-40 are passive. Pulley 40 is pivotally mounted on a suitable pivot plate (not shown) so that it may be located in a belt tensioning position. 
     Idler pinch rollers 42, 43 and 44 are mounted on suitable pivot plates (not shown) biased towards engagement with pulleys 36, 37 and 38 respectively so that the web 5 is pinched between the respective pulley and pinch roller pairs. 
     A magnetic encoder 45 is located on the lower carrier plate 32 adjacent the primary track 34 and the web 5, moving in the track, sweeps past the encoder 45 with its magnetic stripe suitably positioned against the encoder for appropriate storage of information magnetically on the stripe. 
     The carrier plates 32 also have inwardly facing vertically opposed secondary grooves 46 in the nature of tributaries for the primary grooves. Together they define a secondary guide track 46 linking with the primary track 34 prior to the location of encoder 45 on the primary track. An external ticket inserted into the secondary guide track 46 is pinched between a driven roller 47 and idler pinch roller 42 which can be pivoted by solenoid 41 into engagement with either pulley 36 or the driven roller 47 depending upon the need either to advance the web 5 in primary track 34 or the external ticket in secondary track 46. The ticket encoder and drive module 30 also includes sensors 50 to 54 which detect the position of a ticket in the guide tracks 34 and 46. 
     A ticket emanating from the magnetic encoder module 30 passes to a printer module 60 comprising components mounted on a base plate 61, These components include a printer 62 operating in conjunction with a drive platen roller 63 and a print ribbon cassette 64. A ticket ejector 65 is provided for ejecting encoded and printed tickets onto a stacking tray 66. 
     The ticket processing sequence of the ticket issuing device is as follows. 
     The first sensor 50 in the primary track senses the leading edge of the web 5 as it is advanced by operation of the roll stock haul-off means 14, 15 and operates to halt the roll stock feed drive mechanism. This sensor 50 is adjustable to provide a desired length of potential ticket between the leading edge of the web and the guillotine 12 positioned on the web path prior to the entrance to the primary track 34. Upon receiving a demand for the printing of a ticket from a keyboard module (not shown) forming part of the computer facility associated with the ticket issuing device, the guillotine 12 is initiated causing the web 5 to be severed providing an unprinted ticket length between sensor 50 and the guillotine 12. Thereafter the belt drive pulley 36 is initiated causing the ticket to advance along primary track 34 to sensor 51 which senses the leading edge of the ticket and initiates the magnetic encoder 45. As the ticket passes the magnetic encoder the appropriate data is magnetically stored in its magnetic stripe and this data is immediately proof-read by the encoder 60 so that a faulty encoding sequence will initiate an order to reject the ticket. 
     The belt drive 35 proceeds to advance the ticket until sensor 52 detects the trailing edge of the ticket and initiates the print drive platen roller 63. This initiating process also starts the roll stock haul-off drive roller 14, after a suitable pause which is software derived, so that the web 5 once again advances to the sensor 50 before the roll stock feed is terminated. 
     As the ticket passes sensor 53 its trailing edge is detected, the printing device is initiated and the belt drive pulley 36 is stopped. After completion of the thermal print process the exiting ticket is lodged between the ticket ejector roller 65 and its pinch roller 65A. A short pulse of current, again software derived, is applied to the ejector roller motor (not shown). This serves to eject the ticket onto the stacking tray 66. 
     The device is then ready to receive a further ticket demand signal from the keyboard module. 
     Should it be desired to process an external ticket, the latter may be inserted into the secondary track 46 where it is detected by sensor 54. This sensor produces a signal which actuates the solenoid 41 causing pinch roller 42 to swing into engagement with drive roller 47 thereby moving the external ticket into the primary track instead of a ticket obtained from the roll stock as described above. 
     A removable cover (not shown) is provided for the upper housing section 2, Such cover provides an external ticket feed aperture in the front face of the ticket issuing device and also covers the ticket ejector 65 leaving only a processed ticket exit aperture to tray 66.
