DOCUMENT POSITIONING MEANS FOR USE WITH AN IMPRINTER BACKGROUND OF THE INVENTION This invention relates to document positioning means for use with an imprinter and, in particular, document positioning means which. permit positioning of a document such as a sales invoice at one of two positions on the print bed where the first position is removed from the second position both along the length and width of the print bed.

As is well known various credit systems are becoming well known such as BankAmericard, Master Charge, Central Charge, etc. Many commercial establishments find that they must employ more than one credit system in order to provide satisfactory service to their many customers. However, all of the credit systems do not require that the customer identification information imprinted from the customers credit card be imprinted on the sales invoice in the same place. Thus, one credit system will require that the customer identification information be imprinted on an upper middle portion of the invoice while another credit system will require that this information be imprinted on the lower left portion of the invoice.

Heretofore, this problem has been overcome by providing the commercial establishment with a separate imprinter for each credit system honored by the establishment. Of course, such duplication of imprinters is expensive for the commercial establishment and further, an undue number of imprinters at a sales station results in unnecessary clutter where space is normally at a premium. That is, sufficient space should be provided to readily accommodate the merchandise purchased by the customer. However, if this space is taken up with a number of imprinters, inefficiency and unsatisfactory service result.

BRIEF DESCRIPTION OF THE PRIOR ART US. Pat. No. 3,421,436 granted on Jan. 14, 1969 to James M. Patterson Jr. (the present inventor) and Rhodes W. Davis and assigned to the assignee of the present application discloses a document locator for use with a variable amount imprinter wherein the document positioning knob is located away from the print bed and adjacent to the digit selecting knobs. Although the imprinter disclosed in this patent is quite useful in many applications, document positioning is limited to one direction along the print bed-namely, along the width thereof. Further, the positioning knob may be conveniently located adjacent the digit selection knobs because the document positioning means is implemented in a variable amount imprinter. However, the document positioning lever of the instant invention is located at the level of the print bed. However, there is no interference between the imprinter head assembly containing the roller platen and the document positioning lever as will be brought out in more detail hereinafter.

SUMMARY OF THE INVENTION Hence, it is a primary object of this invention to provide a document positioning means for use with an imprinter whereby a document such as a sales invoice may be positioned both along the length and width of the print bed of the imprinter.

It is a further object of this invention to provide an imprinter of the above type wherein the documents correspond to sales invoices of different credit systems.

It is a further object of this invention to provide a document positioning means for use with a non-variable amount imprinter wherein a document may be positioned in one of two fixed positions on the print bed where one position may vary with respect to the other position only along the width of the print bed.

It is a further object of this invention to provide an improved document positioning means for use with an imprinter whereby the customer and dealer information can be accurately positioned at two different positions on two different invoices respectively to thereby facilitate automatic reading thereof.

Other objects and advantages of this invention will become apparent upon reading the appended claims in conjunction with the following detailed description and the attached drawing.

DESCRIPTION OF THE DRAWING FIG. 1 is a plan view of an imprinter having an illustrative embodiment of the document positioning means of this invention, the document positioner being placed in a first setting so as to accommodate the first of two possible invoices usable with the imprinter. The imprinter head assembly containing the platen roller is not shown in this view in order to facilitate understanding of the invention.

FIG. 2 is a cross-section taken along line 2-2 of FIG. 1. In this view the imprinter head assembly is shown.

FIG. 3 is a cross-section taken along line 33 of FIG. 1.

FIG. 4 is a plan view of the imprinter shown in FIG. 1 with the document positioner in its other position so as to accommodate the other invoice usable with the im printer. The imprinter head assembly has not been shown to facilitate understanding of the invention.

FIG. 5 is a cross-section taken along line 5-5 of FIG. 4.

FIG. 6 is a cross-section taken along line 66 of FIG. 4.

FIG. 7 is a fragmentary side view of an illustrative embodiment of a document guide means employed in the invention.

FIG. 8 is a plan view of an illustrative document such as a sales invoice illustrating the location of customer and dealer identification information as required by one credit system.

FIG. 9 is a plan view illustrating another document such as a sales invoice illustrating the location of customer and dealer information as required by a second credit system.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION FIGS. 1-7 illustrate a preferred embodiment of the document positioning means of this invention for use with an imprinter. However, before describing the document locater means in detail, FIGS. 8 and 9 will be discussed in order that the problem solved by this invention may be better understood. FIG. 8 illustrates the document 10 such as an invoice used by one credit system. This credit system requires that the customer and dealer identification information blocks 12 and 14 be imprinted on the invoice in the positions indicated. These invoices are typically read by an automatic character recognition machine which typically operates as a high speed, automatic input device to a computerized billing or inventory system or the like. Thus, it is imperative that the information be fairly accurately positioned on the invoice or else the character reader will not be able to correctly read the imprinted information.

FIG. 9 illustrates another document 16 such as an invoice used by a second credit system. This second credit system requires that the customer identification information 18 and the dealer identification information 20 be imprinted on the invoice 16 at the respective positions indicated in FIG. 9. his clear from a comparison of FIGS. 8 and 9 that the customer and dealer information required by the first and second credit systems varies positionwise on the respective invoices l0 and 16 both along the length and width of the invoices. The customer and

dealer identification information

18 and 20 must also be fairly accurately positioned on the invoice 16 in order to facilitate automatic reading thereof as discussed above.

Referring now to FIGS. 1-7, the document positioning means of this invention will be described. Referring to FIG. 1, there is shown a plan view of an imprinter 22 having a print bed generally indicated at 24. Disposed on the print bed are printing plate 26 which typically may be a credit card and dealer printing plate 28, which typically is permanently affixed to the print bed 24 by means such as

screws

30 and 32. Typically the credit card is held in place by

guides

34, 36, and 38, guides 34 and 36 being secured to the print bed 24 by

screws

40 and 42 respectively while guide 38 is also permanently attached thereto by means not shown but well known to those of ordinary skill in this art. Guide 38 is typically made of a flexible material to accommodate placement of the credit card 26 on the print bed 24. The above described details are well known to those of ordinary skill in this art and form no part of the invention. It should be appreciated that the credit card 26 and dealer plate always assume a fixed position with respect to the print bed 24 regardless of where credit and dealer information is to be imprinted on the document. However, it should be further appreciated that one credit system may position the customer and dealer information on the respective customer and dealer plates differently than another credit system. Thus, this will cause the position of the imprinted information to vary somewhat from one system to another. However, the document positioning means of this invention is needed to effect the amount of positioning required so that a single imprinter may accommodate the invoices of the different credit systems.

Referring to FIG. 2 there is shown a cross-section taken along the line 2-2 of FIG. 1. The imprinter head assembly is located at 44 and mounted therein in a well-known fashion on shaft 46 are

roller platens

48 and 50. Shaft 46 is connected by appropriate mechanical means generally located at 52 and 54 to the side arms 56 and 58 respectively of the head 44. The side arms 56 and 58 each have connected thereto at least two bearings, one of the bearings for side arm 56 being indicated at 60 and one of the bearings for side arm 58 being indicated at 62. The bearings ride within

tracks

64 and 66 respectively disposed along the length at the imprinter sides to facilitate manual or automatic movement of the imprinter head assembly 44 over the print bed to thereby effect imprinting from the customer and

dealer plates

26 and 28 onto a document disposed on the print bed as the

rollers

48 and 50 respectively pass over the

printing plates

28 and 26. The above described operation of the imprinter head assembly 44 and the structure thereof is well known to those of ordinary skill in this art and the details thereof form no part of this invention. It should be appreciated that the

print rollers

48 and 50 are fixed positionwise along the length of shaft 46 and always respectively coact with

printing plates

28 and 26 which, as stated above, are

fixedly positioned with respect to the print bed.

Having now described in general terms an imprinter with which the document positioner of this invention operates, the document positioner will now be described in detail. Referring to FIGS. 1-3 the document positioner is shown in a first position where it will receive a first document 68 shown in phantom lines corresponding for example to the invoice shown in FIG. 8. In order to hold and locate the document in the position indicated in FIG. 1, a pair of bifurcated

members

70 and 72 are mounted on a common shaft 74. Shaft 74 is rotatably positioned with respect to the bottom of print bed 24 by mounting

blocks

76 and 78 which are secured to print bed 24 by appropriate means such as the screws shown in FIG. 1.

Referring to FIG. 2, bifurcated member 72 includes

arms

80 and 82. Connected to arm 80 is an upwardly projecting movable document guide 84 having a seat portion 86. As can be seen in FIGS. 1 and 2 movable document guide 84 is disposed within a rectangular opening 88 provided within the print bed 24. As shown in FIG. 2 the top of guide 84 is disposed below the level of print bed 24 and thus the guide is ineffective to locate the document on the print bed. Rather, when the document positioner is in the position indicated in FIG. 2, this function is served by upwardly projecting, fixed guide member 90 which is fixedly attached to the print bed 24.

The other arm 82 of bifurcated member 72 has attached thereto a right angle member or movable document guide 92,-the right angle being clearly shown in FIG. 1. As can be seen in FIGS. 1 and 2 this member coacts with a right angle opening 94 disposed within the print bed 24. As can be seen in FIG. 1 the right angle member comprises a first upwardly projecting member 96 and a second one 98. Referring to FIG. 2 it can be seen that guide 92 projects upwardly through the opening 94 when the bifurcated member 72 is positioned as shown. Thus, the member 96 positions the invoice 68 along the width of the print bed while the member 98 positions the invoice along the length of the printing bed. In order to limit the upper movement of the right angle member 92 a seat 100 is provided which engages the bottom of the print bed 24 adjacent the opening 94 as indicated in FIGS. 1 and 2 and thus upward movement thereof is limited. Seat 86 performs a similar function when the bifurcated member 72.is switched to its other position.

Referring to FIG. 2 there is shown a lever l02 connected to shaft 74, the purpose of lever 102 being to switch

bifurcated members

70 and 72 to their respective alternate positions. Since bifurcated members-70 and 72 are mounted on common shaft 74 the manual positioning of lever 102 to its opposite positions will simultaneously position bifurcated

members

70 and 72. A block 104 having an opening 106 disposed therein is mounted onto print bed 24 by appropriate means such as

screws

108 and 112. The slot 106 is disposed over a similar opening 114 coaxially disposed within the print bed 24 and shaft 102 projects through the

coaxial slots

106 and 114 so that it may be readily manually operated as indicated in FIG. 2.

In order to securely hold the bifurcated members in their respective alternate positions a pair of

leaf springs

116 and 118 are provided. As indicated in FIG. 2 a narrow indentation or groove 120 is provided in the bottom of base plate 24. The leaf springs 116 and 118 are disposed adjacent one another on opposite sides of the slot 120 as indicated in FIG. 1. The upper ends of the

leaf springs

116 and 118 are respectively inserted in groove 120. The lower ends of the springs 116 are inserted in a slot 122 disposed on the top middle portion of bifurcated member 72 as indicated in FIG. 2. Thus, when lever 102 is in the position shown in FIG. 2, spring 118 is compressed to hold the bifurcated member 72 in the position shown. Switching of lever 102 to its other position, as shown in FIG. 5, will relax spring 118 and compress spring 116 so that bifurcated

members

70 and 72 are held in their other position. Thus, the document positioner will hold the documents firmly in place during an imprinting operation.

Reference should now be made to FIG. 3 which illustrates a preferred embodiment of bifurcated member 70.

Bifurcated members

70 and 72 are constructed exactly the same. However, member 70 is mounted on shaft 74 in a manner opposite to that of member 72. Thus, referring to FIGS. 1 and 3 the portions of member 70 corresponding to the previously described portions of member 72 have the same reference numerals except that they have also been primed for purposes of clarity. In addition openings 88' and 94 are provided in print bed 24 which respectively correspond to

openings

88 and 94 and which serve a function corresponding to these openings.

A fixed document guide 124 is provided on the print bed 24 and is shown in fragmentary cross-section in FIG. 7. The purpose of guide 124 is to facilitate document location on the print bed when bifurcated member 70 is in the position shown in FIGS. 1 and 3 as will be described in more detail hereinafter.

In operation, it will be assumed that the invoice is such as to require imprinting at the upper portion thereof as indicated in FIG. 8. When such is the case, the invoice should be located on the print bed in the manner shown in FIG. 1. As can be seen in FIGS. 1 and 2, lever 102 would be positioned toward the forward portion of the print bed whereby

members

96 and 98 of right angle member 92 will be operative to position the upper right corner of invoice 68; upwardly projecting member 90 will be operative to locate the lower" edge of the invoice; stop 124 will be operative to locate the left edge of the invoice (also see FIG. 7); and guide 84 will be operative to locate the upper left edge of the invoice. Hence, the invoice is now located on print bed 24 in such a manner that when the imprinter head assembly 44 is moved across the print bed the customer and dealer identification information on

plates

26 and 28 will be imprinted in the correct position thereon.

Further, referring to FIG. 4 when it is necessary to imprint on the invoice 68' in the positions indicated in FIG. 9, the lever 102 is switched as indicated in the figure. Hence, when so positioned the

edges

35 and 37 of

card holders

34 and 36 respectively are operative to hold the upper edge of the invoice in place; the edge of lever mounting block 104 is operative to hold the right edge of the invoice; member 84 is operative to hold the lower right edge; and right angle member 92 is operative to hold the lower left corner of the document in place.

By comparing FIGS. 1 and 2 it can be readily seen that the position of invoice 68 is removed from that of 68' both along the length and width of the print bed. Thus, for example in FIG. 1, stop 124 is operative to hold the left edge of invoice 68 in place while member 98 of right angle member 92' is operative to hold the left edge of document 68' in place. Of course, the position of document 68 with respect to document 68 along the length of the bed 24 can be varied by varying the distance between the members which are operative on the left and right edges of the document when it is in the position shown in FIG. 1 and the members which are operable on these edges when the invoice is in the position shown in FIG. 4. Similar considerations apply for varying the distance between document positions along the width of the print bed where it is understood that the width of the print bed extends from top to bottom as seen in FIG. 1 while the length thereof extends from left side to right side. Of course, special document guides such as guide 124 may be employed in place of

edges

35 and 37 of card guides 34 and 36 or edge 105 of block 104 to implement document position variation as discussed above.

Thus, there has broadly been described an imprinter comprising a chassis having a print bed (24) disposed thereon; means (34, 36, and 38) for receiving at least one printing plate (26) disposed on said print bed; four openings disposed in said print bed where two of said openings (94, 88) are disposed above the other two openings (88, 94'); a first pair of movable document guide means (92, 84') operative through the upper two of said openings to hold the upper edge of a first document (68) in place while a first one of said four fixed document guide means holds the lower edge thereof in place in response to said document positioning means being set in a first position; a second pair of movable document guide means (84,92') operable through the lower two openings in said print bed to hold the lower edge of a second document (68') in place on said print bed while a second one of said four fixed document guide means holds the upper edge of said invoice or said document in place in response to said document positioning means being placed in a second position; and roller platen means movably mounted with respect to said print bed so that upon movement thereof over said print bed information on said printing plate will be imprinted on one of said documents whereby a first portion of said first document is imprinted upon when said document positioning means is in said first position and another portion of said second document is imprinted upon when said document positioning means is in said second position. The foregoing language corresponds to that used in the claims.
