Description

DEVICE FOR RECOGNIZING TAPES IN CASSETTES, FLUID DISTRIBUTOR USED IN PARTICULAR FOR THE IMPLEMENTATION OF THE REFRANGING DEVICE

The invention relates generally to a device for re-inking ribbons, in particular those used in typewriters or printers, and more particularly ribbons in cassette.

The invention also relates to a dispenser used, in particular for the implementation of the re-inking device.

In general, it has been noted that ribbons inked for typewriters, or imprinters, more particularly those sold in the form of cassettes have various drawbacks.

One of the main drawbacks lies in the fact that the quantity of ink present on the ribbon being limited, the ribbon is exhausted before the mechanical wear of the fabric which constitutes it renders it unusable.

When the ribbon is contained in a cassette and the use of the ribbon interacts with means allowing the ribbon to pass in front of the striking member, it is usual after one or more scrollings of the ribbon in front of the striking member of the machine to write or from the printer and when the ink supply of the ribbon is exhausted, simply throw away the cassette and replace it with a new cassette, even though the ribbon is still mechanically in good condition.

Various systems allowing such re-inking have already been proposed in the past. These devices are however not very easy to handle.

In addition, the wide variety of ribbons used for typewriters in existence today often makes it impossible to use these systems. re-inking only for a limited number of ribbons.

The invention proposes to remedy these drawbacks in large part by proposing a device for re-inking ribbons, in particular ribbons for typewriters or printers, which is simple to use and can be applied to most types of ribbons inked in cassettes, whatever the type.

The first object of the invention is such a device for re-inking ribbons.

The invention also relates to a removable cartridge which can be used more particularly in the device according to the invention.

The device according to the invention for depositing a uniform longitudinal strip of fluid, in particular ink, on the surface of a tape housed inside a cassette, this tape being unrollable and this so as to allow the scrolling of this ribbon in a region determined outside of and facing the cassette, comprises a plate carrying:

- A first rotary plate around its axis on said plate and intended to receive the cassette, said plate comprising a first axial member excen¬ tré allowing on the one hand, the positioning of the casette on this plate in an orientable manner by pivoting on the surface of the first plate and, on the other hand, this member being associated with means for driving the ribbon by a motor also associated with the plate to produce the movement of the ribbon in said region, when the cassette is placed on the first stage,

- A second plate near the first plate, rotatable about its axis on said plate and comprising a second eccentric member allowing the positioning on the second plate of a dispenser containing the fluid to be deposited on the ribbon, the aforesaid outer region of the tape can be brought into contact with the region or 1 opening dispensing fluid distributor, through appropriate rotations of the two plates around their own axes on the one hand, and the appropriate orientation of the cassette and, if necessary , of the distributor around their eccentric axes, on the other hand.

The two rotary plates are mounted near each other, so that a minimum length of the tape has come out of the cassette to receive the fluid strip or, preferably, when by construction of the cassette, part of the tape is always exposed in a determined region outside the cassette, so that this region can be brought into direct contact with the region or opening dispensing fluid dispenser.

According to a first embodiment of the invention of the invention and when the ribbon is housed inside a cassette having its own own drive allowing the unwinding of the ribbon, the first eccentric axial member allowing the placing the cassette on the first rotary plate comprises a cylindrical recess allowing the setting up of a drive axis having a section coagulating with the complementary section of the drive axis of the ribbon 1 inside the cassette and allows their mutual engagement.

According to another embodiment of the invention, and when the inked ribbon is housed in a cassette having no own drive axis, the first eccentric member, itself capable of being driven by a motor and allowing the installation of the cassette on the first rotary plate comprises two external elements, capable of being associated with the eccentric axis, rotating in opposite directions, applied or applicable in friction against each other and between which the ribbon can be inserted into the aforesaid external region of the cassette, one of these rotary elements then being driven in rotation by the above-mentioned motor and thus allowing the ribbon to run.

A preferred device according to the invention is further characterized in that the dispenser consists of a cartridge capable of containing a fluid, removable, possibly disposable, and capable of being mounted on the second eccentric member or 'to be secured thereto, pivotally around the axis of the above second rotary table.

As regards the dispenser, it may be constituted by any suitable inking system. It 5 may consist of a small cylindrical reservoir containing thick ink, the walls of which are porous or perforated and covered with a fabric or a porous plastic film, which can be installed near the 0 cassette. whose . the ribbon, being in contact with said reservoir, will soak with ink; the inking system can also consist of a gelled ink roll of the solid ink type, installed in the cassette or in the typewriter, mounted pivoting on its axis and being directly or indirectly in contact 55 with the ribbon.

A preferred dispenser according to the invention is provided with at least one fluid dispensing opening or with a fluid ejector having respectively transverse sections allowing the deposition of the unique fluid.

30 ment over a part of the width of the tape running in contact with it.

It goes without saying that the skilled person will be able to choose the appropriate cross sections of

_ ₍ _ the dispenser opening or the ¹ fluid ejector, so as to have a strip of fluid of the desired width.

According to the invention, the deposition on the ribbon of a fluid strip is carried out when a part of said ribbon comes into contact with the dispenser.

The deposition takes place in particular when at least part of the surface of the ribbon is in contact with the fluid dispensing opening or the fluid ejector of the dispenser, this contact being made in particular at the determined region of the ribbon. which is located on the outside of the cassette. Once the contact has been made, a uniform longitudinal strip of fluid can be deposited on the surface of the ribbon by simply making said ribbon pass through the first eccentric axial member carried by the first rotary plate or by an axis. drive coagulating with this organ, this first member or this axis being driven. in rotation by a motor.

According to a particular embodiment of the invention, the member with which the distributor or the cartridge is secured is itself rotary, the second plate itself being provided with means causing the distributor or the cartridge to rotate. .

Advantageously, these means are constituted by gears, arranged in such a way that the rotation of the second plate causes the distributor or the cartridge to rotate, so as to maintain the zone or the ink distributor opening in a same plan. In this way, it will always be easy to bring the strip into contact with the area or opening of the fluid dispenser of the dispenser, by the appropriate rotations of the two plates.

According to a preferred embodiment of the invention, one of the rotary plates can be moved vertically between staggered positions with respect to the other rotary plate, so as to allow the fluid dispensing opening or the fluid ejector to be brought into contact with the moving tape in its contact with it at distinct longitudinal levels of said tape.

The displacement in height ^* of one of the rotary plates can be obtained in a manner known per se, for example by means of a system of collars and spiral discs. the device according to the invention then allows the deposition of several uniform longitudinal strips of fluid on different longitudinal levels of a same ribbon. This could be the case for example, when it is desired to deposit strips of inks of different colors on different levels of the surface of a tape for typewriters.

The invention also relates more particularly to cartridges comprising an enclosure for a fluid and dispensers of fluid, in particular ink, advantageously used in combination with the device described above, therefore capable of being mounted on the one of the plates of the device according to the invention.

The cartridge according to the invention comprising an enclosure for a fluid, closed at one of its extremi¬, and a separate member closing said enclosure at its other end, is characterized in that it comprises means capable of defining two separate openings, these openings bringing the interior space of the enclosure into communication with the outside, and means for closing these two openings.

The cartridge according to the invention comprises appropriate means allowing access to the outside of the fluid contained in said cartridge, as well as means allowing a sealed closure of the cartridge.

Advantageously, the means which constitute the two separate openings and which allow access towards the outside of the fluid contained in the cartridge are located near one of the ends of the cartridge, in particular in the lower part of the cartridge when the latter is placed on the second plate.

Advantageously, the two distinc¬ your openings are located in the same plane perpendicular to the axis of the enclosure. It goes without saying, however, that these two openings can be located in another plane, in particular a plane parallel to the axis of the enclosure.

When this type of cartridge is used, the area or the fluid dispensing opening in contact with which the ribbon comes is constituted by one of said openings, the positioning of the cartridge with respect to the ribbon then being such that the other opening is still uncovered. The scrolling of the ribbon in front of the first opening then produces a suction of ink coming to deposit on the ribbon, while the second opening, uncovered, allows the penetration of air into the cartridge in place of the ink thus sucked.

According to a preferred form of the invention, 1. ' separate member is constituted by a cap mounted frictionally or sliding on the enclosure from the other end thereof, so as to allow relative movements thereof vis-à-vis the enclosure, between a respective first relative position and a respective second relative position. Advantageously, one of the two elements which constitutes the enclosure or the cap comprises two separate openings and the other of the two elements comprises a slot.

When the cap and the enclosure are in their respective first relative positions, the slot of one of the two elements is superimposed on the two separate openings carried by the other element and the cap then authorizes access to the outside of the interior space of the enclosure by means of the two openings and one of the openings can be brought into contact with the ribbon as indicated above.

When the cap and the enclosure are in their respective second relative positions, the two openings of one of the two elements are closed by the wall of the other element which then constitutes the means for closing the cartridge. In this second position, the contents of the cartridge cannot have access to the outside via the two openings.

According to a preferred embodiment of the cartridge according to the invention, the enclosure and the cap are cylindrical, coaxial and engaged in friction, one in the other, the passage from the first to the second relative position, or vice -versa ^* ; being obtained by rotation of one of the two elements with respect to the other around their common axis.

According to another preferred embodiment of the cartridge according to the invention, the wall of the enclosure comprises a slot giving access to the outside, preferably in a plane perpendicular to the axis of said enclosure, and The enclosure comprises an at least partial obturation shutter member subjected to the action of elastic means, pushing this projecting part outwardly through this slot.

The end of this projecting part has a dimension less than the length of the slit and cou¬ smooth therein. Under the action of said elastic means, the projecting part of the shutter protrudes towards the outside of the cartridge. In this first position, the protruding part closes the greater part of the slot formed on the wall of the enclosure and the fluid contained in said enclosure does not have access to the outside.

According to another aspect of the invention, the _ς projecting part of the shutter member can retract into the enclosure under the effect of a thrust exerted from the outside and directed towards the inside of the pregnant. In this position, the projecting part no longer completely closes the slot provided on the wall of the enclosure and thus releases on its two sides, two openings at the two opposite ends of the slot.

The fluid contained in the enclosure can then have access to the outside and be deposited on the strip passing in front of one of these openings, the other opening being then not covered.

According to a preferred form of the invention, the removable shutter or¬ is constituted by a roulet¬ capable of rotation about its own axis, preferably toothed or rough surface, having an overall diameter greater than the length of said slot, the axis of this caster mounted inside the enclosure being subject to the action of the above elastic means for exiting at least partially out of the cartridge through the slot, this axis being able to be moved towards the interior under the action of an external thrust against the action of the elastic means.

According to this embodiment, the caster can only partially exit the enclosure through the slot, the overall diameter of said caster being greater than the length of the slot.

Advantageously, the axis of the caster is part of the elastic means, more particularly of a spring wedged inside the enclosure and tending to exert a force directed towards the exterior of the enclosure so as to partially cause it to exit. a part of the caster through the slot to the outside of the enclosure.

According to this embodiment, the caster - capable of rotation along its own axis has teeth or is provided with a rough surface, for example based on felt. The external thrust is then exer¬ ced by the tape brought into contact with the caster, near one of the ends of the slot. The deflection of the ribbon then causes the wheel to rotate. In this way, the teeth of the caster or the rough surface thereof contribute to the ejection, out of the enclosure, and, when the caster is subjected to rotation, to the deposition of the fluid, in particular contained between two teeth or on the rough surface, on the part of the tape coming into contact with it.

According to another preferred embodiment of the invention, the enclosure is cylindrical, and the separate member closes the enclosure at its other end is a 0 coaxial cylindrical cap mounted sliding on the enclosure, this cap being itself - even provided with a slot.

In a first relative position of the cap vis-à-vis the enclosure, the slot of the cap coincides with that of the enclosure, the removable shutter member 5 then protruding partially out of the enclosure at through the two overlapping slots.

In a second position obtained by rotation of the cap along its own axis relative to the enclosure or vice versa, the wall of the cap seals the 0 slot made in the enclosure and the removable member is retracted with the inside the cartridge against the action of elastic means, in particular of the spring.

Tary supplémen¬ features and advantages will become obvious ^"in light of the description c tion more detail below of embodiments of the invention given by way of illustration and not limitation, as well as on examining the figures which relate thereto and in which: _ - FIG. 1 represents a top view of an embodiment of the device re-inking according to the invention, FIG. 2 represents an exploded front view of the device of FIG. 1, _ιn - FIG. 3 is a section through the device of FIGS. 1 and 2, the different parts being in their assembled position, 4 shows a top view of the device 1 'according to the invention igure 1, in which ₁₅ is arranged a first type of cassette, Figure 5 shows a top view of the device of the invention according to Figure 1, on which is placed a second type of cassette, FIG. 6 represents a side view, -, ₀ partially in section of the two main constituent elements of a first embodiment of the cartridge according to the invention,

- Figures 7a and 7b show side views, partially in section from two different angles -, _c tincts, of the main elements of a second embodiment of the cartridge according to the invention, Figures 8a and 8b show sections perpendicular to the axis of the cartridge of FIGS. 7a and 7b respectively in the rest position and

30 in use position.

In particular, there is shown the ribbon con¬ held in its. cassette, represented by traces in phantom, pressing against one of the sides of the caster, and driving it in rotation when it is itself brought to pass in front of one of the ends of the slot . In Figures 1 to 8, the same references designate the same parts.

Now considering Figures 1, 2 and 3, the re-inking device of the invention comprises a plate (1) on which is disposed a first rotary plate (3).

The first plate (3) comprises a first eccentric axial or¬ gane (5), allowing the installation of a cassette, in this case a hollow cylindrical guide (5) passing through the plate. This hollow cylinder per¬ puts in place two complementary elements (5a) and (5b) capable of engaging one another and one of which (5a) is capable of being driven in rotation by the motor (9), in particular by means of an endless screw (7), and the other (5b) is capable of engaging with the axis of the cassette or a drive axis of the ribbon housed inside the cassette.

The plate also comprises at its peripheral surface a housing (11 which can receive several other elements (5b), represented by (13), which can be accommodated in the eccentric hollow guide (5) and the upper parts of which adapt to the different types of existing cassettes.

The plate (3) also comprises a particular device (15) which can be housed in the hollow guide (5), and usable with cassettes having no internal axis for driving the ribbon.

The device (15) is provided with two rotary elements (17) rotating in opposite directions and between which the ribbon can be inserted. A tab (19) is provided to separate the elements (17) from one another, in order to allow the release of the ribbon between the two elements (17). the plate (1) further comprises a second plate (21) rotatable about its axis, placed near the first plate (3) and on which is mounted a second eccentric member (25) allowing the establishment of a fluid distributor (27).

A gear system (23, 29), provided below the plate (21), connects the axis of the second plate (21) to the eccentric member (25), so that the distributor (27) integral with the member (25) is subjected to rotation when the second plate is also subjected to rotation.

A cavity (31) is provided on the peripheral surface of the plate (21), for the finger of the user who can thus rotate the plate (21) manually around its axis.

A control panel (33) and a reserve (35) for storing several distributors (27) are also mounted -on the jplatinum (1). •

Figures 2 and 3 show more clearly the way in which the different parts of the device of the invention are assembled.

In particular, the eccentric member (5), carried by the first plate (3), interacts with two parts (5a), (5b) one of which (5a) is connected to the drive system (7) motor (9) and the other (5b) is provided with a male section engaging with the female sec¬ tion of the drive axis of the cassette, when the latter comprises one.

The plate (1) also comprises below the second plate (21) a system of collars (22) and secondary plates (24, 26) which can rotate about their common axis and which makes it possible to vary the height of the second plate ( 21) relative to the first plate (3), so that the distributor (27) placed on the second plate (21) can be brought to heights different from the first plate (3) and the ribbon placed on this plate (3).

Figures 4 and 5 show the device of the invention in use, with two different types of cassettes.

Considering FIG. 4, a cassette (37) containing a ribbon (39) is placed on the first plate (3). The cassette (37) has a drive mechanism (38) which is specific to itself and which allows the complete movement of the tape outside the cassette, in a determined zone (41) situated between two tabs ( 43). Once the cassette (37) placed on the first plate (3) thanks to the axis (5b) (not shown in FIG. 4) coming to engage in the drive mechanism (38) of the cassette, the second plate (21) is manually rotated through the housing (31) until the distributor (27) mounted on the second eccentric member (25) comes into contact with a part (45) of the ribbon (39) at the level of the specified region (41). The cassette is then ready to be re-inked.

By activating the motor (9) (not shown in FIG. 4) via the control panel (33), the eccentric member (5) drives the drive mechanism (38) of the cassette and the ribbon (35) runs between the two arms (43) of the cassette.

The part (45) of the ribbon (39) then receives a uniform longitudinal strip of the fluid contained in the dispenser (27).

The mechanism by which the fluid leaves the dispenser and is deposited on the part (45) of the ribbon will be explained in more detail in the following.

Now considering FIG. 5, a cassette (37) is placed on the first plate (3).

Cassette (37) has no mechanism clean drive allowing the tape to scroll

(39).

In this case, the device (15) mounted on - the eccentric member (5) (not shown) is used. The

D ribbon (39) is inserted between the two rollers (17).

The second plate (21) is rotated so as to make contact between a part (45) of the tape (39) and the dispenser (27) in a determined region (41) external to the cassette (37).

The device (15) integral with the motor (9)

(not shown) then allows the scrolling of the ribbon

(39) in contact in its part (45) with the distributor

(27) and a longitudinal strip of fluid can be applied to the tape (39).

The contacting of the ribbon and the dispenser is generally obtained by subjecting the second plate (21) to a rotation along its own axis.

However, it is also possible to facilitate contacting by also turning the first plate (3), depending on the dimensions and the characteristics characteristic of each type of cassette used.

FIG. 6 represents a first embodiment of the cartridge of the invention.

Referring to this figure, the cartridge comprises an enclosure (47) closed at its upper end, and provided on its side wall and near its lower end with two openings (49).

The cartridge also comprises a separate cylindrical member (51) constituting a closure cap for the enclosure at its lower end, this cap being provided with an axis (53) allowing it to be placed on the re-inking device of the invention. . The thus closed enclosure is filled or capable of being filled with a fluid.

The wall of the cap (51) is further provided with a slot (55) near the base of said cap.

The enclosure (47) is mounted on the cap (51) by friction, the two elements being able to rotate relative to each other about their common axis.

The rotation of one of the two elements (47, 51) par. relative to the other makes it possible to obtain the superposition of the slot (55) and of the two separate holes (49) in a first relative position, and _. 1 Closure of the two holes by the wall of the enclosure (47) in a second relative position.

In the first relative position defined above, the fluid contained in the enclosure (47) can exit through the slot (55) and the two holes (49).

In the case where the cartridge is used in the re-inking device of the invention, the ribbon comes into contact with the cartridge at only one of the two holes (49), the other having to remain uncovered.

The scrolling of the ruba. on the first hole (49), when the holes overlap with the slot (55), allows the entrainment of a uniform band of the fluid contained in the enclosure (47), in particular ink, and its deposition on the part of the ribbon coming into contact with it, as air enters the enclosure (47) through the other of the holes (49) and tends to push the fluid still contained in the enclosure (47) towards the bottom, so that the fluid always comes out evenly from the enclosure (47).

When the cartridge is not in use, it suffices to turn one of the two elements (47, 51) relative to the other. In this way, the two holes (49) and the slot (55) no longer overlap and the wall of the enclosure (47) closes the slot (55). The fluid can no longer exit the cartridge.

The figures (7a, 7b) represent a second embodiment of the cartridge of the invention.

According to this embodiment, the cartridge includes a cylindrical chamber (47) closed at its f _c Tremite top and provided on its side wall with a slot (48) near its lower end.

The cartridge further comprises a separate member (51) constituting a cap, mounted frictionally and sliding on the enclosure, and closing it at its lower end.

The cap (51) has on its lateral wall a slot (55) near its lower end.

The enclosure (47) and the cap (51) are mounted so as to be able to perform rotations with respect to one another along their common axis.

A toothed wheel (57) is housed inside the cap (51), at the level of the slot (55).

. The caster (57) is retained by means of a spring (59) which on the one hand tends to push the caster there.

(57) outwardly through the slot (48) on the one hand and on the other hand, through the slot (55), when the two slots are mutually superimposed.

The diameter and the thickness of the wheel are chosen so that it can partially exit from the slot, while being blocked at one time from its exit by its diameter which prevents it from completely leaving the slot. cap.

When the two slots (48, 55) are superimposed, and the caster (57) partially exits the cap, the cartridge nevertheless remains practically closed provided that the caster (57) is not subjected to rotation. In fact, the projecting parts towards the outside of the caster come close to the ends of the superposed slots (48, 55), so that the latter are practically closed, at least regard to the viscosity of the fluid which is sufficient to prevent it from coming out of the cartridge.

Now considering FIG. 8b, it appears that the caster (57) can partially exit the cartridge through the slots (48) and (55) only when these are superimposed.

The caster (57) has teeth on its periphery which entrain the fluid contained inside the enclosure when the caster is rotating.

In the first relative position of the cap (51) with respect to the enclosure (47) in which the two slots (48, 55) are superimposed, the caster (57) partially exits the cartridge through the slots (48, 55) under the action of the spring.

When a ribbon (39) comes into contact with the cartridge at the level of the caster (57) and the slots (48, 55), the ribbon tends to push the caster (57) in part towards the interior of the cartridge , against the action of the spring.

The roller (57) then reveals two separate openings (61, 63) at each of the corresponding ends of the superimposed slots (48, 55). When the ribbon passes in contact with one of these two separate openings (61, 63), it drives the wheel in rotation. This then contributes to the extraction of the fluid to be deposited on the ribbon outside the enclosure in the form of a uniform strip, while the other opening allows the entry of air inside the cartridge. .

The arrow (c) indicates the direction of travel of the ribbon in relation to the cartridge.

When not in use, the cartridge is easily sealed by subjecting one of the two enclosure or cartridge elements to a rotation, so that the slots respectively carried on the walls of these elements no longer overlap.

The wall of the enclosure then tends to push the roller (57) towards the inside of the cap (51), _c against the action of the spring (59).

In a final relative position, the caster (57) is completely retracted into the cap (51), the slots respectively carried on the walls of these elements no longer overlap and the wall of the enclosure ₁₀ completely closes the slot ( 48).

When the enclosure closing member is not formed by a sliding cap on the lower part of the enclosure, the caster can be pushed inwards by an adhesive strip (65) at the _ . _c level of the slots (48, 55), in particular when the cartridge is not used, as shown in FIG. 8a.

If the cartridge of the invention has been more particularly described in the context of the re-inking device of the invention, the fact remains that it can be applied with the same effectiveness to other applications .

Mention will be made in particular of the use of the car¬ key of the invention for depositing a strip of glue 5 ^ on a surface capable of receiving it, in particular a sheet of paper or an envelope, or the deposition of a colored liquid on a surface.

Likewise, the cartridge of the invention can be used alone, for example by holding it in the hand. In this case, it is the cartridge which runs in contact with the surface on which it is desired to deposit the fluid contained in the cartridge, and the surface is then immobile with respect to the cartridge.

It goes without saying that the invention is not limited to the particular exemplary embodiments which have been described in the foregoing, but embraces all the variants to the contrary. Variants of the invention consist in particular of changes in the respective positions of the different parts used. Other modifications, in particular with regard to the form and the method of assembling the various parts of the invention must be considered to remain within the scope of the invention.

Device according to claim 4, taken alone ^' or in combination with claims 5 to 7, characterized in that the cartridge comprises: an enclosure (47) for a fluid, closed at one of its ends, and a member separate (51) closing said enclosure (47) at its other end, means capable of defining two separate openings (49), preferably in the same plane perpendicular to the axis of the enclosure (47) and near from one of its ends, these openings (49) putting in communication with the outside the interior space of the enclosure (47), and - means for closing these two openings (49).

9. Device according to claim 8, carac¬ terized in that the separate member of the cartridge is constituted by a cap (51) mounted frictionally or sliding on the enclosure (47) from the other end of that so as to allow relative movements of the latter with respect to the latter between respective first relative positions and respective second relative positions, in that one of the two elements (47, 51) which constitute the enclosure and the cap has two separate openings (49) and the other a slot (55) revealing the two openings (49) when the enclosure (47) and the cap (51) are in their respective first relative positions, the cap (51 ) then authorizing. Access to the outside of the interior space of the enclosure (47) via the two openings (49); and the two openings of one of the above two elements (47, 51) being closed by the wall of the other element (47, 51), when the enclosure (47) and the cap (51) occupy their second positions respective relative, said wall then constituting the above sealing means.
