Description

Device for accurate placement in relation to a printing mechanism of writing material which is manually fed into the receiving chute of a calculator or similar office machine.

The present invention relates to a device for ensuring accurate placement in

relation to a printing mechanism of writing material which is manually fed into the receiving chute of a calculator or the like

office machine.

What is common when typing

special thing about a writing material such as checks and the like, is that the machine operator inserts each sheet of writing material into a precisely shaped receiving chute and guides the sheet

by hand until it hits a margin stopper which forms a writing position, and this stopper is part of the chute construction. —

Although this manual placement of the writing material is sufficient when needed

is written on it must only be present in a roughly defined writing field, i.e. can be considered acceptable input, even if it is

any deviations within the permissible limits it

one way or another from the end of the written material,

require certain procedures as at present

used in modern office operations by

processing of written material (such as automatic reading of all typed characters such as

is present on checks and the like) that it

typewritten text that is present on the written material is kept within a precisely delimited

pressure field, i.e. that it does not vary in any

significant degree one way or the other

from the end of the written material.

It is already known to arrange an automatically acting mechanism for providing

see off a margin stroke for inserted writing material so that the writing material is moved from an initial inserted position to a final position. However, these known mechanisms are associated with the disadvantage that they form an integral part of a flat surface in the machine and must be carried out in this at the same time as the production of the plate.

The purpose of the invention is therefore to provide a cheap and easily manufactured device which can be easily built into a machine after manufacture and which can be easily adjusted so that the machine can print on the inserted writing material in variable places in order to meet the individual customers' requirements. This purpose is achieved by the fact that, according to the invention, a device is provided for accurate placement in relation to a printing mechanism of writing material that is manually fed into the receiving chute of a calculator or similar office machine, which device comprises a main drive mechanism, a fixed stop that cooperates with the bottom edge of the introduced writing material in order to thereby determine the line to be printed, a margin stopper against which a vertical edge of the writing material is closely adjacent at the introduction into the chute, a moving mechanism for displacing the margin stopper a predetermined stretch at right angles to the direction of introduction of the writing material and mechanisms which holds the writing material firmly during printing, which device according to the invention is characterized in that the moving mechanism is operated by an organ in the main drive mechanism and comprises a drive rod which is connected to the margin stopper and with a pivotably suspended operating arm which is articulated with a cam arm, which A cam arm cooperates with a cam on the member in such a way that at the beginning of each machine operating cycle the drive rod operates the core stopper so that the writing material is placed in a precise position in relation to the printing mechanism.

Other details and characteristics of the invention will emerge from the subsequent description of the embodiment shown in the drawings.

Fig. 2 shows a front view of a fixed writing material chute and parts of the associated mechanism.

Fig. 6 shows a very enlarged detailed view of part of the mechanism in fig. 5 after the line 6-6 with the mechanism in an effective position in relation to the associated written material.

Machine mechanism.

Because the mechanism that will ensure the operation cycle in e.g. a calculator is well known in the art, only that part of the mechanism that is necessary to understand the invention will be included. By operating either an electric motor or an operating handle (not shown), a rear machine drive shaft 15 is caused to rotate first clockwise and then clockwise back to its rest position (Fig. 5). As shown in fig. 1, the drive shaft 15 is stored between the machine's left and right vertical side plates 10 and 11 and forms the lower support device for a pair of separate side frames 16a and b in the printing device, the frames being further supported at their upper ends by a fixed shaft 17 which runs between the side plates 10 and 11 (see again Fig. 5). Turning the rear drive shaft 15 during each machine operation initiates several machine operation functions, one of which is the activation of a plurality of locking parts (not shown) for releasing associated type hammers 18.

Release of the locking parts allows the type hammers 18 to strike against selected type parts 19 which sit on the upper ends of associated type arms 20. These type arms 20 are differentially regulated near the beginning of each machine operation cycle corresponding to the digits of the number selectively entered into the machine. When each type part 19 is struck by its associated hammer 18, which takes place near the middle of the machine's operating cycle, this type part 19 is driven into contact with a paper plate 14. By means of an ordinary colored ribbon (not shown), what is written on the type part is printed on the written material that is adjacent to the plate 14.

Writing material receiving chute.

Along the front of the plate 14 and placed between the plate and the associated type arms 20 (fig. 1 and 5) there is a writing material receiving chute which is indicated by the number 25. The chute 25 is fixed in place by means of a pair of jack parts 26 ( only one is shown in Fig. 1) to the upper side of a horizontal bar 13. The channel 25 (Figs. 2 and 5) comprises a rear

wall 27 and a couple of connected front wall parts

28 and 29 which are separated from the rear wall in a fixed

relationship by means of suitable devices, here the rivets 31 which pass through them and through an intermediate spacer strip 30 which runs along the edges of the wall parts. The right end of the back wall 27 and the front wall 28 are likewise separated by spaces and fixed by means of further rivets 31 which pass through yet another spacer strip 32 which is placed between the walls. As can be seen best in fig. 2 thereby both the right-hand end and the top pen of the chute -25 are free and ready to receive checks and similar writing material which is inserted by hand between the rear wall 27 and the connected front wall parts 28 and 20. The vertical setting of the writing material inside the chute 25 is achieved automatically when the lower edge of the writing material rests on the upper surface of the spacer strip 30 and the horizontal setting of the writing material is determined by how far to the right along the chute the machine operator guides this by hand.

Reference is again made to fig. 1 where it can be seen that the rear wall 27 of the channel 25 is equipped with a cut-out part 27a immediately behind the group of type arms 20 and that another cut-out part 28a is produced in the front wall part 28 of the channel. The cut-out 28a allows the selected type parts 19 when they are hit by the associated pressure hammers 18, after impinging on the common ink ribbon, to contact any writing material placed inside the chute 25 and to force the area of it placed immediately behind the selected type parts 19 (such as the stip- guide line zone indicated at 33 in Fig. 2) through the cut-out 27a into the pressure stop against the plate 14 at the rear. The zone 33 (fig. 2) can thus be considered as if it represents a writing-receiving field on the writing material which is inserted into the channel 25, or the normal writing line in the calculator. In both cases, it is in this zone that the selected type parts 19 will be driven towards the paper plate 14 which is behind. Triggering of the type hammers 18 near the mid-cycle of a machine operation will cause a written impression to be made either on the writing material located in the chute 25, or on a writing material on the plate itself 14 when there is no writing material inside the chute 25, both being at the zone 33 on fig. 2.

In order to facilitate the insertion and removal of the writing material in the chute 25, the upper left corner of the front wall part 29 is bent forward (fig. 2), the same applies to the rest of the upper edge part of the wall part 29 and the upper edge of the wall part 28 (fig. .5). The rear wall 27 has its upper edge bent backwards (fig. 5). The connection between the front wall parts 28 and 29 can be made with the help of any suitable device such as with the help of the rivets 31. In order to be able to immediately see the writing material inside the channel 25, the front wall part 29 can be shaped by a any suitable transparent material.

Writing material stopper and moving mechanism.

With a card chute 25 as described above, the writing material can be moved to the right along this until it comes into contact with the above-described spacing strip 32. This placing of the writing material in position will be the normal practice followed when the longitudinal placement of a machine-printed information on it does not have to be completely accurate — i.e. within defined narrow limits. When a specific, precise position for the writing-receiving zone on the writing material that is placed in the funnel is very important, such as e.g. for reasons stated above, the original manual placement of it inside the chute 25 is inadequate, because there is no assurance that the machine operator will always be lucky in getting the writing material to abut against the strip 32 or any other fixed stop device provided. In order to ensure an exact position for the writing material which is inserted into the chute 25 — i.e. so that what is pressed on it will always be placed in an exact and non-varying zone along this, the following described mechanism is brought to work under the machine's working process, so that it really moves the writing material from its original (rough) position inside the card chute enough to bring its writing-receiving zone into the correct printing position in relation to the type arms 20.

Further cut-out parts 27b and 28b are provided in the rear wall 27 and the front wall part 28 respectively (fig. 1 and 2) and arranged in relation to each other. These further cut-out parts are illustrated here as upright parts of the previously described cut-out parts 27a and 28a. Down inside the card chute 25 at the cut-outs 27b and 28b (fig. 1 and 2) extends a marrow stopper or shift arm 34 (fig. 4) which is designed so that it slides freely along the width of the cut-outs 27b and 28b. The upper end part of the arm 34 lies freely inside the channel 25, while the lower end of the arm 34 in the tail part 34a slidingly engages with the channel 25 — i.e. goes sliding down between the rear wall 27 and the front wall part 28 in this. In reality, the tail portion 34a of the stop and shift arm 34 forms a lower guide to maintain smooth movement of the arm within the chute 25. A writing material receiving portion 35 is attached to the upper end of the arm 34 so as to project over the chute 25. As shown in fig. 1, the part 35 is press-fitted onto an upper flap part 34b of the arm 34. Another stop part 36 for the writing material is attached by means of the screws 37 to a central part of the arm 34, so that it will be inside between the cut-outs 27b and 28b. As is best understood from fig. 4, both parts 35 and 36 are of such a construction that they form a pair of horizontally spaced and vertically aligned V-shaped grooves which are positioned to receive the right edge of the writing material inserted into the chute 25. As the best can be seen in fig. 2, the parts 35 and 36 of the arm 34 form a positive stop device in the longitudinal direction for the writing material, when this is inserted by hand into the chute 25. Another upper part 34c of the arm 34 and which likewise protrudes over the chute 25, is bent backwards, so that it protrudes somewhat behind this. A hoop clip 38 is attached to the lower surface of the part

34c, which clip 38 is attached by means of a locking screw 39 to the right end of a drive rod 40. As shown in fig. 1, the rod 40 extends from the bracket 38 a precise distance to

left along the rear edge of the rear wall 27 of the chute, and is then bent downwards and pivotally connected to the upper end of an associated operating arm" 41 which has a spring 41a attached

towards him to bring it back into position.

The holding brackets 42 and 43, both of which are attached to the rear surface of the rear wall 27, carry

sliding, with the help of the bearing parts 44 (fig. 5) the part of the drive rod 40 which extends along the back wall (fig. 1).

As shown in fig. 1, the operating arm 41 has its lower end supported on a support cam 45, which cam 45 projects backwards from a bracket 46 which is fixed to the lower left corner of a machine rear frame plate 12. Another cam 47 which projects backwards from the bracket 46 rotatably carries a cam arm 48, which cam arm 48 has a roller 49 held in engagement against a cam surface provided on the outer edge of a curved cam 50 which is attached to the left end of the machine's rear drive shaft 15. As shown in Fig . 3, the cam part 50 has an upper arm part 50a which is attached to a drive disc 51 which is arranged on the shaft 15.

A joint 52 operatively connects the operating arm 41 and the chamber arm 48 together, so that a movement imparted to the chamber arm 48 by oscillating the cam part 50 will be transferred to the operating arm 41 which in turn causes the rod 40 to be pushed back and forth along the fixed chute 25. As is well known, the joint 52 which is shown here (fig. 1) is of the adjustable type so that one can have an exact and yet easily changeable operative relationship between the arms 41 and 48.

The first tilting movement imparted to the machine's rear drive shaft 15 (counter-clockwise in fig. 5 and clockwise in fig. 3) causes the rod 40 to be moved to the left (fig.

2) and to the right (fig. 1), and in the same way will

the return tilting movement imparted to it (clockwise in Fig. 5 and anti-clockwise in Fig. 3) by the spring 41a causes the rod 40 to be brought back to its starting position. This movement of the rod 40 is transferred to the stop and shift arm 34 whereby, which can best be seen in fig. 2, the arm 34 is first moved a precise distance to the left along the chute 25 and then returned to the right to its starting position — this happens for each machine work cycle that is started. This movement from the rest position of the arm 34, which rest position is determined by the attachment location of the arm on the right end of the drive rod 40, will take place before the middle of each machine work cycle. while the return of the arm 34 to the rest position does not take place until near the end of each machine operation. Although both the rest positions and the extent of movement of the stop and shift arm 34 can easily be adjusted to suit

for the needs of the moment, the most important factors are that the part 36 of the arm 34 moves freely within the cut-out portions 27b and 28b of the chute, and that the amount of movement therein, together with the part 35 which also sits on the arm 34, is sufficient to go engaging with and moving to the left along card chute 25 any writing material manually placed in its immediate vicinity. For this purpose, it is considered that a moving movement on a writing material in the vicinity of 16 mm, such as

from the position on the part 35 which is drawn up with solid lines (Fig. 2) to the position which is drawn up with dashed lines, will be effective to finally place the writing material which is roughly placed by the machine operator, when it was originally placed in chute 25. This means that the machine operator has successfully performed the operation of inserting the writing material as long as its right edge comes within 16 mm of the vertically aligned V-shaped grooves in parts 35 and 36.

Of course, the exact distance that the stop and shift arm 34 travels so that the writing material with which the parts 35 and 36 are engaged is brought to place its writing-receiving field in exact alignment with the group of type arms 20. This is the zone 33 where the writing on the writing material will occur near the mid-cycle of the machine operation, which is just after the stop and shift arm 34 has completed its function of moving the writing material from the coarse setting to the fine setting. It is obvious that the rough setting of the writing material is determined by where the machine operator manually places this, either lying against the parts 35 and 36, or with a space from them. Although a single portion 35 or 36 would normally be sufficient to accomplish the desired writing material moving task, the provision of both ensures accurate placement of the writing material even if a portion of its right edge or perhaps a corner zone is folded in or otherwise broken. Earlier shifting or similar attachment of the written material to an invoice or bill can often destroy a corner part of it, likewise tearing the written material off a block or out of a book causes this to often have a very uneven edge.

F' ast tension me canism

for written material.

After the writing material, through the influence of the stop and shift mechanism just described, has been moved to a fine setting in relation to the type arms 20, it is important that the writing material is held there during the entire printing operation which is now carried out by the associated type hammers 18. In order to to ensure this, another mechanism, which is activated for each machine operation cycle, engages the writing material immediately after its fine placement is completed and clamps it against the plate 14 until the writing operation is completed.

As shown in fig. 2, further cut-out portions 28c in the wall 28 form a pair of downwardly projecting fingers 55, one located near each end of the pressure zone 33. Both their ends terminate somewhat below the pressure zone. These fingers 55, taking into account the type of material used to make the front wall part 28, can easily be forced out of the plane of the part 28 by any suitable device, after which they will automatically return to their normal plan flight with section 28.

A device for forcing each of these fingers 55 backwards, causing them to squeeze the writing material sitting in the chute against the plate 14, is shown in fig. 5. As shown, a clamping slide 56 by means of elongated slots 57, which grips a pair of guide cams 58 with spaces between and which protrude from each of the side frames 16a and 16b (see also fig. 1), is arranged for horizontal displacement movement along the upper end of each of the frames 16a and 16b. As can best be seen in fig. 1 and 2, each of these sliders 56 is shaped so that they have an upper nose part 56a which is aligned in relation to the front surface of the associated one of the fingers 55. In each case, a spring 59, which is stretched out between a cam 60, forces on the slide 56 and the foremost of the control knobs 58, the slide 56 yielding forwards, i.e. to a normal position where the upper nose part 56a on this is kept out of engagement with the associated finger 55. As illustrated in fig. 5, such a normal spring-loaded position for each slide 56 is limited by the rear wall parts in the elongated slots 57 which engage with the associated control cams 58.

A drive arm 62 is pivotally arranged on each end of a printing mechanism shaft 61, so that there is one arranged on each of the outer sides in each side frame 16a and 16b. Each of these arms 62, which is most easily seen in fig. 5, is resiliently forced clockwise under normal tension from an associated spring 65 which is stretched out between an upper cam 63 and the previously described cam 60 which sits on the associated slide 56. How far this arm 62 is tilted in a clockwise direction is determined by another cam 64 on this and which engages with a lower tail part 56b on the associated slide 56. The spring 59 has sufficient strength to normally keep the slide 56 out of engagement with its finger 55. The spring 65 has, in addition to it is sufficiently strong to normally hold the arm cam 64 against the lower tail part 56b of the slide — i.e., spring biasing the drive arm 62 clockwise — a force sufficient to overcome the spring 59 and pull the slide 56 rearward along the guide cams 58 when a clockwise rocking motion is imparted drive arm 62.

A pair of cam arms 66 (fig. 1) are attached to the machine's rear drive shaft 15, each of which has a drive cam 67 which is aligned in relation to the lower end part 62a (see fig. 5) of an associated drive arm 62. When oscillating the cam arms 66 during each machine operation cycle first counterclockwise and then counterclockwise (Fig. 5), each of the drive arms 62 is caused to tilt an exact clockwise distance when the lower end portions 62a thereof are touched by the cam 67 and then allowed to return toward clockwise to the rest position (as shown) when cam 67 disengages. When tilted in a clockwise direction, which occurs just before the middle of the machine operating cycle, each of the drive arms 62 by means of its spring 65 causes the associated slide 56 to be moved rearward to an extent which, as illustrated in detail in Fig. 6, the aligned finger 55 bends into engagement with the plate 14 behind. The part of the writing material which is located in the groove 25 behind each finger 55 will naturally, even if it is not shown in the drawings, be positively clamped by the finger against the plate 14. As can be seen in fig. 2, this effectively holds the writing-receiving field of the check, which is the zone 33, firmly in contact with the paper plate 14. Taking into account the radial location of each of the chamber arms 66 on the main drive shaft 15, the timing of the clockwise tilt of each drive arm 62 is found — and therefore the rearward movement of the slides 65 — takes place immediately after the described writing material stopping and moving mechanism has completed its fine placement of the writing material which is originally coarsely placed inside the chute 25. This is, of course, just before the beginning of the writing operation which the machine performs. The return of ■ each driving arm 62 clockwise to the rest position under the action of the spring 59 takes place immediately after the writing operation is completed on the writing material in the chute, by oscillating the chamber arms 66 back to their starting positions. At this point the fingers 55 spring back to their normally flat positions, thus releasing the writing material and allowing the machine operator to remove it from the chute 25.
