Abstract
Description
- The invention relates to an imprinter for imprinting characters from a character source member such as a credit card onto a document of the type comprising a base member having means for receiving a character source member and means for receiving a document, a carrier supporting imprinting means to press the document against the character source member, the carrier being slidably movable over the base member on a track means provided on the base member.
- The invention is characterised in that the carrier includes a pair of spaced-apart bearing means which engage opposing faces of the track means with a pinch action.
- One advantage of the invention is that by virtue of the fact that the bearing means engages the track with a pinch action a particularly smooth movement of the carrier over the base member is achieved.
- In one embodiment of the invention the track means comprises a pair of elongate, track members on opposed sides of the base member, each track member having outwardly directed track faces.
- This arrangement provides smooth movement over the length of travel of the carrier.
- In a particularly preferred embodiment of the invention the bearing means comprises bearing rollers engaging opposite track faces of the track means with a pinch action embracing the track faces therebetween.
- The rollers assist in providing a smooth movement of the carrier across the base.
- Preferably the track faces comprise an upper track face and a lower track face, the lower track face being inclined at an angle to the upper track face, and one of the bearing rollers is a tapered roller to engage the inclined track face.
- This arrangement provides a particularly smooth action and by virtue of the fact that the lower track face and roller are tapered facilitates adjustment of the pinch action.
- In one embodiment of the invention the bearing means comprises at least one pair of pinch rollers, namely an upper pinch roller and a lower pinch roller, at opposite sides of the carrier member located outwardly of and bearing inwardly against the track means.
- Preferably two pairs of pinch rollers are provided to engage the track means.
- This assists in balancing the carrier member and in providing a smooth operation.
- Typically the lower pinch rollers are of tapered inwardly convergent conical configuration.
- The advantage of this type of roller is that it provides a particularly good pinch action and smooth operation while allowing adjustment for maintaining pinch action as the rollers and/or track faces become worn.
- In aparticularly preferred embodiment of the invention the means for receiving a document comprises a flat upwardly facing panel forming a document supporting surface.
- In a preferred embodiment of the invention the document supporting panel and the track means are an integral plastic body having the track means formed therein.
- The integral plastics construction facilitates ease and cheap- nessof manufacture and assembly and provides an imprinter of robust construction.
- Preferably the carrier member is a reciprocative carrier member transversely spanning the base member and movable longitudinally over the document supporting panel from a start position adjacent one end of the panel to a reversing return position adjacent the other end of the panel, the imprinter roller means comprising at least one imprinter roller for engaging a document when positioned on the panel overlying a character source member during movement of the carrier member between the start and return positions.
- In one embodiment of the invention the base member and carrier member include co-operating means for moving the imprinter roller from a raised inactive position to a lowered imprinting position engaging the document to imprint characters from a character source member onto a document during movement of the carrier member between the start and return positions.
- In one embodiment of the invention the imprinter roller is mounted on a stepped diameter shaft, the shaft being mounted in shaft support members of the carrier member in which the shaft is slidable axially to raise and lower the imprinter roller between print and non-print positions so that the imprinter roller prints in only one direction of travel of the carrier member.
- Preferably the co-operating means comprises cam follower members on the carrier member for axially shifting the shaft and cam abutment formations positioned on the base member to engage the cam follower members at the return and start positions of the carrier member to activate the cam follower members to move the shaft.
- In a preferred embodiment of the invention the roller means comprises two imprinter rollers for selectively engaging a document, one of the rollers engaging the document during movement of the carrier in one direction and the other of the rollers engaging the document during movement of the carrier in the other direction.
- The particular advantage of this arrangement is that good quality printing is achieved of the characters from both a credit card and merchants plate. Often the characters on these two sources are worn to varying degrees so that a single pass with a roller gives weak print from one or other source.
- In one embodiment of the invention a single cam abutment is provided and link means are provided between the cam followers for movement of both shafts when one of the cam followers engages the cam abutment.
- The advantage of providing a single cam abutment instead of two abutments is that this reduces the height that the abutment surfaces project from the base and hence the overall height is decreased.

The taperedpinch rollers 27 are removable from theshafts 28 to accommodate spacer washers (not shown) mounted behind therollers 27 for altering the gripping pressure with which thepinch rollers track 20. A retainingmember 29 is releasably mounted on thecarrier 16 to retain and accommodate removal of the taperedrollers 27. Each retainingmember 29 in this case comprises apin 30 which engages a corresponding hole (not shown) in thecarrier member 16 with a type of bayonet action. Thus, by rotating the retainingmember 29 in the direction of the arrows A of Fig. 8 the retainingmember 29 may be removed to remove the taperedrollers 27. - The
imprinter rollers 17a and b are rotatable on steppeddiameter shafts carrier 16 so that they may be moved towards and away from thebase 4 in use, so that therollers shafts support members 34, also moulded integrally with thecarrier 16. Eachmember 34 has an open endedslot 35 to engage theshafts pin 36 in the base of eachslot 35 is provided to bear on theshafts Springs 37 bias theshafts pins 36 in theslots 35. Theshafts support members 34 and the larger and smaller diameter portions of the shaft are joined by a taperedportion 41. Thus, on sliding the shafts axially through theslots 35, the height at which therollers 17a and b are set above thebase 4, is varied. When thepins 36 bear on the larger diameter of theshafts base 4, however, when the pins bear on the smaller diameter of theshafts base 4. - Means for raising and lowering the rollers 17 by moving the
shafts single cam follower 42 extending from a camfollower block member 43. Thecam follower block 43 includes asidewardly projecting tongue 44 which engages in a complementary shapedchannel groove 45 provided in a secondcam follower block 46 to facilitate movement between theblocks cam follower 42 engages a single cam provided by acam surface 47 on acam block 48 integrally moulded with thebase 4. It will be apparent that thecam surface 47 is provided in the line of travel of thecarrier 16, and when thecam follower 42 engages thesurface 47 both cam follower blocks 43,46 are moved thereby causing therollers - A
second cam block 49 with acam surface 50 is moulded integrally with the base and acts on thecam follower 42 to return theshafts rollers - Returning now to the
base 4 and thehandles handle 6 is moulded integrally with thebase 4. However, thehandle 5 is removable to open one end of each of thetracks 20 so that the carrier may be removed for any repairs or adjustments which may have to be carried out. For example, should it be necessary to remove or replace an imprinter rollers or to vary the pressure of thepinch rollers tracks 20 by the addition or removal of washers (not shown) on theshafts 28 of the taperedrollers 27. Fig. 11 illustrates thehandle 5 and as can be seen, adovetail projection 55 is provided which slidably engages correspondingdovetail slot 56 in thebase 4. Further spring clips 57 on thebase 4 enlace thehandle 5 throughslots 58, thus locking thehandle 5 firmly in position. To remove the handle, thehandle 5 is slid downwardly of thebase 4 and removed. It will be appreciated that any suitable joint may be employed between thehandle 5 and thebase 4 to facilitate ease of removal. - In use, the
