Description
~q~ 3 PRINTING APPARATUS
BACKGROUND OF THE INVENTION
The invention relates to printing apparatus and rnore particularly to apparatus for printing such documents as rectangular sales slips.
s Prior conventional printing apparatuses for sales slips, which have been generally incorporated in cash registers or point of sale terminals, have generally been of the vertical slot type or flat bed type. In the verticAl slot type, the document must be inserted in the side or top of ~he machine, an operation that is relatively inconvenient and awkward for an operator to perform. If small sales slips or other articles accidentally drop to the bottom of the slot, they are not retrievable by the operator9 causing substantial trouble. Pressure rolls are provided for incrementing the document in its printing slot, and these generally must be lifted either by a magnet or manually to insert the document.
Generally also, there is a limitation on paper size with the vertical slot type of printing apparatus.
With the flat bed type of prin-ting apparatus, printing is sometimes reversed as the sales slip exits the machine and must be turned upside down to be read. The number of lines of print are generally limited with this type of printing apparatus, and the lines of print are not visible to the operator substantially at the same time as they are printed so that errors are not readily apparent.

SUMMARY OF ll-IE INVENTION
... . . _ It is an object of the presen-t invention to provide an improved printing apparatus in which the documen-t to be printed is placed by the operator in a substantially horizontal disposition ini-tially and exits the machine in a substan-tially vertical disposition to be readily available t~ the operator.
It is also an object of the invention to provide an improved prin-ting apparatus in which the lines of print provided by a print head are visible to the operator just af-ter being made so that errors rnay be ;(~ readi1y ascertained.
1i~e inlproved printing apparatus of the invention in a preferred -Forrn includes a guide having an initial -flat substan-tially horizontal portion on which the document to be printed may be initially placed, a final vertical portion providing a vertical passage from which the document exits after printing and in which a print head prints the lines of print on the document and an intermed;ate curved portion which bends the document as it is pushed into the machine. The machine on its top includes an opening provlding a line of sight for the operator so that he can examine each of the lines of print just after it has been made by the print head of the apparatus. Pressure and drive rolls are provided to be effective on the document to be printed as it travels vertically upwardly on the final portion of the guide; and the drive rolls are controlled initially so that they continuously rotate to move the document in a continuous motion until the line for the first print line is reached, and then the rolls are incrementally rotated so as to increment the document past the print head. The print head is controlled so as to accomplish its printing by traversing across the print line between ;ncrements of the document. A keyboard may be located just below and in front of the initial substantially horizontal guide por-tion, and thus the keyed entry as printed may be inspected by the operator located at the front of the machine at the keyboard.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a fragmentary side elevational view of the printing apparatus of the invention;
~ .
.
3~
. 3 FIG. 2 is a -Fragmentary plan view, par-tially schematic, of the printin~
apparatus; and FIG. 3 is a plan view of a document which may be printed by the printing apparatus.
The printing apparatus comprises a print head 20 which may he reciprocated on a center line 22 by any suitable propelling mechanism. The print head 20 may be of the wire printer -type, for examp1e; and it is disposed opposite a platen 2~ for printing an elongate rectangular sales slip or other documen~ 26 resting upon the pla-ten 24. The motion of the prin-t head 20 on the center line 22 may be sensed by any sui-table sensing means, such as a sensor 28.
The apparatus comprises a lower guide 30 providing a nearly horizontal flat guide plate portion 30a, a vertical flat guide portion 30b and a curved guide portion 30c formed on a radius 30d connecting the guide por-tions 30a ancl 30b and extending for about 90 degrees. The apparatus also comprises an inner guide 32 which has a vertical surface 32a extending parallel with the guide portion 30b to provide a vertical passage A between these two surfaces, a horizontal guide surface 32b and a guide surface 32c extending upwardly at an angle with respect to the surface 32b, with the surfaces 32b and 32c being disposed opposite the curved portion 30c of the lower guide 30. The guide 32 also has a surface 32d extending upwardly and at an acute angle with respect to the guide portion 30a so as to provide a document receiving throat 34. An aligning rail 36 for the document 26 forms one end of the -throat 34 and acts to guide the document 26 into the apparatus. A keyboard 38 is provided in front of and below -the aligning rail 36 and horizontal guide portion 30a as shown in FIGS. 1 and 2.
A pair of document drive rolls 40 and an opposite pair of pressure rolls 42 are provided in the passage A between the surface 32a and guide portion 30b. The pressure rolls 42 are held in forceful but yieldable relationship with the drive rolls 40 by any suitable means. The drive rolls 40 are propelled from a motor 44 through spur gears 46 and 48.
The motor 44 is preferably of the electrical stepping type.
A pair o-f document sensors 50 and 52 are disposed at the bo-ttom of the vertical passage A, and a pair of sensors 54 and 56 are disposed at the upper end oF the passage A. The motor 44 is under the control of controls 58; and controls 58 are under -the control of sensors 28, 50, 52, 54 and 56.
The keyboard 38 is connected to a memory 60 of any suitable type as by means of data transferring bus 62. Memory 60 is also connected to the print head 20 as by means of data transferring bus 64 and has control conllections with controls 58.
In order to print the document 26, it is placed on the horizontal portion 30a of the lower guide 30 in a substantially horizontal disposition. The document is then manually pushed so that its forward end contacts the curved guide portion 30c, and the document is thus bent against whatever inherent resilience the document material may have and moves upwardly in the passage A. The forward end of the document 26 when it passes between the sensors 50 and 52 causes the controls 58 to so operate on the motor 44 that the motor drives the drive rolls 40 and thus the pressure rolls 42 at a continuous speed.
As the document 26 is moved farther upwardly in the passage A under manual force, its forward end eventually enters the nip between the rolls 40 and 42; and these rolls then move the document at a uniform speed upwardly in the passage A. I~hen the forward end of the document passes between the sensors 54 and 56, these so operate on the controls 58 that the motor 44 is then caused to incrementally rotate the rolls 40; and the document incrementally moves upwardly in the passage A. The print head 20 under the control of controls 58 traverses across the document 26 for each of the increments of rotation of the rolls 40 and prints a line of print, such as the print line a, for the increment of rotation of the rolls 40. This printing occurs in the vertical passage A and on the platen 24 which supports the document during printing. The sensor 28 connected with the controls 58 assures that the motor 44 cannot be effective to provide another increment of rotation of the rolls 40 until a print line has been completed. Succeeding lines of print, such as lines b, c, d, etc., are printed on successive increments of rotation of the rolls 40.
The controls 5~3 may also be under the control o-f the keyboard 38 so that a reciprocation of the print head 20 does not take place until a line of print has been put into memory 60 by means of keyboard 38. In this case, the line oF print a is first keyed in-to the keyboard 38 and is pu-t into melnory 60. The print head 20 then traverses across -the document Z6 and prints the first line a. The drive rolls 40 are then effective to move the document 26 upwardly in the passage A for an additional increment; the keyboard 38 then has its second line of print entered into it and thereby into memory 60; and the print head 20 is then reciprocated and prints the second 1ine of print b on the document 26.
Subsequently, the docunlent 26 is incrementally moved upwardly in the passage A; and the succeeding lines of print c, d, e, etc., are printed by the print head 20 as it -traverses across the document 26.
Ihe apparatus is provided ~ith an ope~ning 66 in its top so that there may be a line oF sight 68 toward the platen 24. Thus, as each subse(~ufn~ line is printed, the operator may check the accuracy of the printed line by viewing along the line of sight 68.
Advantageously, the printing apparatus allows the operator to lay the documen-t 26 on a flat, substantially horizontal, bed (guide portion 30a) and to push it away from him into the machine, which is very natural from the operator's standpoint. The operator places the document 26 in contact with the aligning rail 36, which is on the right side of the line of movement of the document 26, into the appara-tusi and the document 26 is thus registered in its proper line of movement. The document 26 is pushed straight in toward the back of the machine with a slight pressure sideways, to the right as seen in FIG. 2, to maintain registration of the document. The portion 30c of the lower guide 30 is formed on a generous radius (30d); and this may be, for example, 1 3/4 inches (4.44cm) to route the document 26 upwardly in passage A without any substantial manual force required in order to cause the document to bend through substantially 90 and without any permanent deformation or bend lines being provided in the document. The sensors 50 and 52 just above the radiused portion 30c of the guide 30 start the feed rolls 40 which need not be lifted or lowered to be effective; and once the document is under.control of the.feed rolls 40, the operator can relax his force to move the clocument upwardly through the vertical passage A.
The document 26 is then automatically incremented through the printing transaction and is ejected out of the top of the passage A and out of .
6 ~ ~L~
the top o-f the machine to be re~dily available to the operator. Each oF
the lines of print as it is caused by the keyboard 38, for example, is readily visible, right side up, to the operator on the line oF sight 68 as head 20 moves along the center line 22 off of the line of print just printed, so that the operator can determine whether the line of print is without error. The printing on the lines a, b, c, d, e, etc., appears to the operator in the order in which the printing was keyed in from the keyboard 38 and can be immediately read as the document exits the machine. Since printing is done as the document is moved in a single direction through the machine, the document may be of any reasonable length with a correspondingly great number oF lines oF print.
In the even-t that a document is accidentally dropped into the document e~it slot (the vertical passage A) from the top of the machine, the document may be easily retrieved either by moving it upwardly out of the passage A or off of the substantially horizontal flat guide portion 30a if the document moves Far enough and around the curved guide portion 30c. The guide por-tion 30a is located just above the keyboard 38, so the guide portion 30a is not only easily within reach for retrieval of documents but also is withln easy reach for inserting documents into the machine for printing in the usual manner.
