INK ROLLER ASSEMBLY FOR LABEL PRINTING AND APPLYING ~CHINE
BACKGROUND OF THE INVENTION
Field of the Invention -The present invention relates to a label printing and applying machine, and more particularly to an ink roller assembly for use with such machine.
Description of the Prior Art - In a conventional ink roller assembly, there is a handle member which is operable for enabling installation of the ink roller assembly in the labelling machine and for enabling subsequent removal. Typically, the handle member has a coil spring mounted in it and is removably attached through the coil spring to a rocking level which, in turn, is attached to the leading end of an ink supply device.
The handle member protrudes from the leading or front end of the ink roller assembly. This presents no difEiculty if the ink roller assembly is used in a label printing and applying machine in which the ink roller protrudes from the ;
front of the machine after the ink roller has rolled forward over the type surfaces being inked. However, if the protruding handle member is used in a label printing and applying machine in which the ink roller is moved back and forth wholly inside the space defined by the machine frame, the handle member abuts the platen at the bottom of the machine or other elements inside the frame, and the iink roller assembly cannot move inside that ,~
space.
SUMMARY_OF THE INVENTION
~; The present invention seeks to provide an ink roller assembly for use in a label printing and applying machine, which ink roller assembly can be moved back and forth inside the space defined by the body of the machine without interference to -: ~ ', "i "
..... . ' ~ ': ' .. .
l~g~ 2 movement of the ink roller assembly from its handle member.
The present invention further seeks to provide such an ink roller assembly, in which replacement of the ink roller is easy.
A further aspect of the present invention is to provide such an ink roller assembly which can be reliably retained in the support member of the link mechanism of an ink supply device and which can be smoothly attached thereto or removed therefrom.
The ink roller assembly of the present invention is usable with a label printing and applying machine that includes a printing device having a type surface, at least one ink roller, an ink supply device for turning the ink roller over the type surfaces of the printing device for supplying the same with ink and a stationary platen onto which a label is ~ed. The printing device is movable toward the platen to bring its type surface into engagement with the label on the platen to imprint the label. The label printing and applying machine is of the type in which the ink roller is made movable back and forth within the space defined by the machine frame.
Briefly, the ink roller assembly of the present invention comprises an ink roller frame, handle means and locking means. An ink roller is rotatably supported to the ink roller frame. The handle means is shiftably attached to the ink -~
roller frame wall and is shiftable with respect to the ink -~
roller frame wall. The handle means may be shifted in an upraised position at which the handle means are upraised off the ink roller frame to enable the handle means to be operated for attachment to and removal of the ink roller assembly from the machine. The handle means may be shifted to a lowered position at which the handle means are lowered toward the ink roller L3Z ~ ~
frame so that the handle means are not upraised when the ink roller assembly is moved over a type surface. The locking means lock the handle means at the lowered position. The handle means and the wall are respectively shaped where they are connected to cause the locking of the handle means. The ink roller frame wall has a recess defined therein and the handle means includes a portion, near where the handle means are attached to the ink roller frame, which portion is shaped and positioned for engaging the frame wall at the recess. ~s the handle means are being lowered to the lowered position, entry of the portion into the recess is resisted by the frame wall. The portion overcomes -the resistance and snaps into the ink roller frame wall recess when the handle means are at the lowered position.
The handle means may comprise a pair of manually graspable, openable handle elements which are hingedly connected ;
to the ink roller frame so that they may be pivotally raised and moved together to effectively form an integral structure when the ink roller frame is attached to and removed from the support member, and so that they may be pivoted down and separated while the type surfaces are being inked. Locking means are provided for locking the handles in their lowered positions.
In addition, the ink roller assembly may comprise guide means for guiding the support member when the latter is `~
attached to the leading end of the ink supply device and retaining means for retaining the ink roller frame in the ;~
support member.

DESCRIPTION OF THE PREFERRED EMBODI~IENTS
The first embodiment of the present invention is now described. The ink roller assembly A according to the present invention is attached, when used, to an ink supply device B of the type that is located inside the machine ~L~9~13~:
Erame and which is equipped with a link mechanism and is mounted in the label printing and applying machine, as shown in Fig. 1.
The label printing and applying machine comprises a grip 1 which is integral with a pair of side frames 8 of the label printing machine. A hand lever 2 is made swingable, when manually squee~ed~ abou* a pivot shaft 3 toward the grip 1, and the hand lever 2 is biased apart from the grip 1 by the action of a return spring 7.
The hand lever 2 has a front portion which is bifurcated to form a pair of yokes 4. A printing device 5 is attached to the leading or front (left) ends of the yokes. The bottom of the printing device carries one or more imprinting type surfaces 6 which have to be inked. The link mechanism for the ink supply device B is a paired arrangement, with the s~me lin~ mechanism on each s,ide.
! Each side of the link mechanism is multi-articulated, and has three fixed support points, i.e. two pivot shats 30 and 31 which are pivotally supported on the yokes 4 and a pivot shaft 32 which is mounted in the side frames 8 of the machine . ,~
At the leading or forward ends of the link mechanism~
a support member 20 is attached. ~n ink rollqr frame 10 of the ink roller assembly A is removably attached to the support member.
As shown in Figs. 2 - 4, the ink roller frame 10 has a U-shaped cross-section. There is a main ink roller 16 o a larger diameter and an auxiliary ink roller 18 of a smaller diameter. Both ink rollers are impregnated with 9~3Z
ink,~ They are rotatably mounted such that their respec*ive 'roller shafts 17 and 19 are supported at the side walls lld of the ink roller frame 10. The side walls lld have engage-ment grooves 12, which extend longitudinally along the walls.
There are corresponding engagement projections 21 formed inside both side walls of the U-shaped support member 20.
The projections are received in the engagement grooves 12 - when the frame 10 is slid into the support member 2~.
As seen in Fig. 3, there is a pair of openable handle elements 13 that are attached to the bridge wall lla of the ink roller frame 10. The centrally located bases of the handle elements 13 are formed with eccentric portions 13a which are shaped to have their greater effective diameter when the handle elements are at their downwardly folded orientation. The eccentric portions 13a are pivotally sup-ported by a pair of pivot pins 14. These pillS are spaced apart and` are mounted to a pair of attachment portions 15 that protrude rom the bridge wall lla o the ink roller frame 10. ~loreover, the eccentric portions 13d engage the bottom wall of a recess llb, which is formed in the bridge wall lla of the in~ roller frame 10. The side ends of recess llb are defined with retaining ends llc.
To attach the ink rolleT assembly A to or to remove lt from the link mechanism of the ink supply device B, the paired handle elements 13 are raised up and together, as shown in Fig. 2, so that they may be manually,grasped and pinched for the desired handling. A~ter the attachment of the ink roller assembly, the paired handle elements 13 are pivoted down in the directions of the arrows shown in Fig.
3. During the descent of the handle elements, the eccentric ~, ~7~3Z
portions 13a of the knob elements 13 are turned about their respective pivot pins 14 over the retaining ends llc of the frame 10 mtil they snap into engagement in the recess llb.
This locks the handle elements 13 in their loweTed flat positions.
At the exteriors of both side walls o~ the support member 20, there is a respective pivot pin 22, which is pivotally supported in the connecting links 26 of the link mechanism o Fig. 1. A pair o~ guide members 23 are attached to the exteriors of and extend longitudinally along the side walls of the support member 20. The guide members 23 are brought into abutment engagement with rollers (not ; !
shown) that are located at the inside of the guide links 43.
Located centrally along both side walls of member 20, there is a respective depending lug having a respective retainin~
hole 25 for a spring 24 which is mounted on the respective pivot pin 22.
The operation o the ink supply device E and of its link mechanism is now described. Starting when the ink roller assembly A is oriented substantially upright and in a stationary condition at the front of the la~el printing and applying machine, as shown in Pig. 1, the hand lever 2 is then gripped or squeezed through its full stTokeO This moves the ink roller assembly A rearwardly past the platen 33, and such motion applies ink to the type surfaces 6 of the printing device 5. The ink roller assembly travels rearwardly until it is inverted and accommodated wholly inside the frame of the label printing and applying machine, and is in the condition shown in Fig. 2. Once the assembly A has moved inside the machine rame, the type surfaces 6 of the printing device 5 abuttingly engage the platen 33 to print a label 27 with the desired information.

When the hand lever 2 is gripped slightly (e.g. by an angle of 3 degrees), the yokes 4 are correspondingly turned slightly counterclockwise (or down~Yard), as viewed in Fig. 1~ about the pivot shaft 3. This causes the multi- .
articulated link mechanism o the ink supply device B attached .
to those yokes 4 to shift such that the lifting portions 37 of the rocking links 36 are brought into abutment engagement with the abutment pins 35 of the opening links 34. Since the pivot sha~ts 30 and 31 which are pivotally supported on the yokes 4 are moved downward with the yokes, a pair of operating links 38 which are supported pivotally on the side frames 8 of *he machine are moved rearwardly or to the right at their movable pins 39 and substantially upwardly at their movable pins 40. At the same time, the rocking links 36 are turned counterclockwise about the pivot shafts 31.
The rocking links 36 are made to slide rightwardly by guiding the pivot pins 22 for the support member 20 and ~he ink roller frame 10 in the horizo:~tal slots 44 of the guide links 43 while keeping the pivot pins 22 pushed to the upper ends of the vertical slots 41 of the rocking links 36 by the action of the springs 24 During this sliding operation, the main ink roller 16 rolls over the type suraces 6 of the , :
printing device 5, while being elastically held there, thus efecting the desired ink application.
Simultaneously with the first stage ink application~
the rocking links 36 are turned counterclockwise about the pivot shafts 31. As a result, the.lifting portions 37 at the ends of the rocking links 36 are brought into abutment against the abutment pins 35 o the opening links 34 ~Yhich are in engagement with the other opening links 45. The . ~ 9 ~
abutment impact of the li:Eting portions 37 upon the abut~ent pins 35 overcomes the actions of springs 46, thus further rocking the opening links 34 in the clockwise direction. As a result, the retaining projections of the opening links 34 are disengaged from the other opening links 45 so that both links 34 and 45 are brought into their released ~or lifted) conditions. Meanwhile, the opening links 34 are rocked . .
clockwise about the pivot shafts 30 while the other opening links 45 are moved counterclockwise about the movable pins 47. In accordance with these sequential operations, the auxiliary ink roller 18 applies ink to the type surfaces 6.
Meanwhile, the ink roller assembly A with the ink rollers l~ -and 18 passes over the platen 33 which is located below the -printing device 5.
Upon completion of the second stage ink application, :
the pivot pins 22 of the ink rollers are in abutment engagement , with the rearmost ends of the horizontal slots 44 of the ~ , guide links 43. ~hen the hand lever 2 is further gripped, the guide links 43 and the,rocking links 36 are rocked counterclockwise and the respective movable pins are moved until the in~ rollers are accommodated or housed in a center portion o the space defined by the side walls 8. The ink roller frame 10 with the two ink rollers 16 and 18 is stored .
in its inverted position inside of the label printing and applying machine at the back of ~he printing device 5.
Then, the regulating projections 48 formed on the opening links 34 abut against the dislocated connecting links 49 to stop further motion of the respective links. The link mechanism thus dislocated returns to its stationary condition of Fig. 1 upon release of the hand lever 2 after the printing device 5 has accomplished its printing operation upon the label 27 that has been delivered onto the platen 33.

,: : r 7~32 In the second embQdiment of ink roller assembly, shown in Figs. 6 and 7, elements that correspond to those in the first embodiment are correspondingly numbered with reference numerals that are raised by 100.
The ink roller frame 110 has a U-shaped cross-section. There is a main ink roller 11~ of a larger diameter and an auxiliary ink roller 118 of a smaller diamcter. Both of these ink rollers are impregnated with ink. They are rotatably mounted such that their respective roller shafts 117 and 119 are supported at the side walls llld of the ink roller frame 110. The side walls llld have engagement grooves 112, which extend longitudinally along the walls.
There are corresponding engagement projections 121 formed inside both side walls of the U-shaped support member 120.
The projections 121 are received in the engagement grooves 112 when the frame 110 is slide into the support member 120.
Outside both side walls of support member 120, there are respective longitudinally extending guide members 123 which project toward and past the open end of the U-shaped member ~0 120.
As seen in Figs. 6 and 7, there is a ~air of openable handleelements 113 which are attached to the center of the bridge wall llla of the ink roller frame 110 at pivot Pins 114. The handle elements 113 are made o~ a flexible material, such 2S a synthetic resin. Their feet have eccentric portions 113a formed on them, which are shaped to have a greater effective diameter when the handle elements are at their folded orientation. The handles 113 have retaiJlin~
projections 113b at their leading ends. These are bent in shape and reduced in thickness, 10~713~, The eccentric foot portions 113a are made openable or foldable down around the pivot pins 114, and these pins are mounted to a pair of attachment portions 115 protrudi from the bridge wall llla of thc ink roller frame 110.
Moreover, the eccentric foot portions 113d are made engageable with a recess lllb, which is formed in the bridge wall llla of the ink roller frame 110, Recess lllb has retaining ends lllc, The retaining projections 113b are sized and shaped to be snap fitted into the retaining notches 123a, which are formed in the pair of guide members 123 mounted to the support member 120.
When it is intended to attacll the ink roller assembly ~ of the second embodimellt to the support member 120 at the link mechanism of the ink supply device B, the paired handle elements 113 are raised inwardly to each other and into their upright positions, as shown in Fig. 6 and in broken lines in Fig. 7. Then, the upright handles 113 thus integrated are manually pinched together so that the engagement grooves 112 of the ink roller frame 110 may receive the ~
engagement projections 121 of the support member 120, thus ;
finishîng the attachment of the ink roller frame 110 to the support member 120 in smooth fashion. After that, the paired handles 113 are brought down and outwardly into their lowered positions, as shown in Fig. 7, so that their retaining projections 113b may be snapped again into the retaining notches 123a at the guide members 123 of tlle support memher 1~0. This snap action is aided by the flexibility of the handle elements 113.

While the handle elements 113 are pivoting downwardly, their eccentric foot portions 113a are $urned about their respective pivot pins 114 and in doing so, they pass over the retaining ends lllc of the frame 110 until they are snapped into engagement with the rece~s lllb. This locks the handle elemen*s 113 in their lowered, flat positions~
In case the ink supply in the ink rollers 116 or-llB is exhausted, or in case the lnk rollers themselves become unsuitable for further use due to wear, the ink roller assembly A as a whole is removed from the support member 120 of the link mechanism of the ink supply device B
and is replaced by another such assembly equipped with new ink rollers. During the removal of assembly A, the opposite ;
procedure to the attaching operation is followed. The paired handles 113 at the ink roller frame 110 are released from the retaining notches 123a of the guide members 123 and then are rotated to their raised positions so that they may permit and do not block extraction of the ink roller frame 110 .
As with the first embodiment of ink roller assembly~
the attachment and removal of the ink roller assembly A is accomplished with the labeling machine stationary in the condition of Fig. 1~ in which the support member of the link mechanism of the ink supply device B is in its protruding position at the ront end of the label printing and applying machine.
- At the outside of both side walls of the support member 120, a respective pivot pin 122 is formed. These are pivotally supported in connecting links 26 of the link mechanism of Fig. l. The paired guide members 123 are .. .. .. ....
~(~)97~3Z :
broùght into abutment engagement w;th rollers (not shown) that are located at the inside of guide links 43. Depending beneath the side walls of support member 120 are depending lugs each having a respective retaining hole 125 therein for receiving a spring 124. The other end of each spring is mounted on the respective pivot pin 122.
The use and function of the installed second - embodiment of ink roller assembly are the same as for the first embodiment.
As has been described above, the ink roller assembly according to the present invention is equipped with an ink roller frame which is removably attached to a support member that is attached to the leading or forward end of the link mechanism of an ink supply device. A pair of openable handles that are formed with a locking device are hinged to the ink roller frame such that they can be manually raised to unlock the ink roller assembly when that assembly is to be attached to or removed from the link mechanism.
When it is intende~ to ink the type surfaces, the ; 20 handles are locked in their lowered positions even during the turning motions of the ink supply rollers. Thus, ink supply -~
can be attained without inviting abutment of the ink roller frame against the platen which is disposed below the printing device. , Another advantage of the present invention is that ; -";~.
the ink roller assembly can be reliably retained in the support member of the link mechanism of the support member.
Furthermore, replacement of the ink roller assembly can be accomplished remarkably smoothly and without requiring that unnecessary pushing and extracting forces be applied. The invention also prevents the fingers of an operator from being stained Wit}l ink.

DESCRIPTION OF THE PREFERRED EMBODI~IENTS
The first embodiment of the present invention is now described. The ink roller assembly A according to the present invention is attached, when used, to an ink supply device B of the type that is located inside the machine ~L~9~13~:
Erame and which is equipped with a link mechanism and is mounted in the label printing and applying machine, as shown in Fig. 1.
The label printing and applying machine comprises a grip 1 which is integral with a pair of side frames 8 of the label printing machine. A hand lever 2 is made swingable, when manually squee~ed~ abou* a pivot shaft 3 toward the grip 1, and the hand lever 2 is biased apart from the grip 1 by the action of a return spring 7.
The hand lever 2 has a front portion which is bifurcated to form a pair of yokes 4. A printing device 5 is attached to the leading or front (left) ends of the yokes. The bottom of the printing device carries one or more imprinting type surfaces 6 which have to be inked. The link mechanism for the ink supply device B is a paired arrangement, with the s~me lin~ mechanism on each s,ide.
! Each side of the link mechanism is multi-articulated, and has three fixed support points, i.e. two pivot shats 30 and 31 which are pivotally supported on the yokes 4 and a pivot shaft 32 which is mounted in the side frames 8 of the machine . ,~
At the leading or forward ends of the link mechanism~
a support member 20 is attached. ~n ink rollqr frame 10 of the ink roller assembly A is removably attached to the support member.
As shown in Figs. 2 - 4, the ink roller frame 10 has a U-shaped cross-section. There is a main ink roller 16 o a larger diameter and an auxiliary ink roller 18 of a smaller diameter. Both ink rollers are impregnated with 9~3Z
ink,~ They are rotatably mounted such that their respec*ive 'roller shafts 17 and 19 are supported at the side walls lld of the ink roller frame 10. The side walls lld have engage-ment grooves 12, which extend longitudinally along the walls.
There are corresponding engagement projections 21 formed inside both side walls of the U-shaped support member 20.
The projections are received in the engagement grooves 12 - when the frame 10 is slid into the support member 2~.
As seen in Fig. 3, there is a pair of openable handle elements 13 that are attached to the bridge wall lla of the ink roller frame 10. The centrally located bases of the handle elements 13 are formed with eccentric portions 13a which are shaped to have their greater effective diameter when the handle elements are at their downwardly folded orientation. The eccentric portions 13a are pivotally sup-ported by a pair of pivot pins 14. These pillS are spaced apart and` are mounted to a pair of attachment portions 15 that protrude rom the bridge wall lla o the ink roller frame 10. ~loreover, the eccentric portions 13d engage the bottom wall of a recess llb, which is formed in the bridge wall lla of the in~ roller frame 10. The side ends of recess llb are defined with retaining ends llc.
To attach the ink rolleT assembly A to or to remove lt from the link mechanism of the ink supply device B, the paired handle elements 13 are raised up and together, as shown in Fig. 2, so that they may be manually,grasped and pinched for the desired handling. A~ter the attachment of the ink roller assembly, the paired handle elements 13 are pivoted down in the directions of the arrows shown in Fig.
3. During the descent of the handle elements, the eccentric ~, ~7~3Z
portions 13a of the knob elements 13 are turned about their respective pivot pins 14 over the retaining ends llc of the frame 10 mtil they snap into engagement in the recess llb.
This locks the handle elements 13 in their loweTed flat positions.
At the exteriors of both side walls o~ the support member 20, there is a respective pivot pin 22, which is pivotally supported in the connecting links 26 of the link mechanism o Fig. 1. A pair o~ guide members 23 are attached to the exteriors of and extend longitudinally along the side walls of the support member 20. The guide members 23 are brought into abutment engagement with rollers (not ; !
shown) that are located at the inside of the guide links 43.
Located centrally along both side walls of member 20, there is a respective depending lug having a respective retainin~
hole 25 for a spring 24 which is mounted on the respective pivot pin 22.
The operation o the ink supply device E and of its link mechanism is now described. Starting when the ink roller assembly A is oriented substantially upright and in a stationary condition at the front of the la~el printing and applying machine, as shown in Pig. 1, the hand lever 2 is then gripped or squeezed through its full stTokeO This moves the ink roller assembly A rearwardly past the platen 33, and such motion applies ink to the type surfaces 6 of the printing device 5. The ink roller assembly travels rearwardly until it is inverted and accommodated wholly inside the frame of the label printing and applying machine, and is in the condition shown in Fig. 2. Once the assembly A has moved inside the machine rame, the type surfaces 6 of the printing device 5 abuttingly engage the platen 33 to print a label 27 with the desired information.

When the hand lever 2 is gripped slightly (e.g. by an angle of 3 degrees), the yokes 4 are correspondingly turned slightly counterclockwise (or down~Yard), as viewed in Fig. 1~ about the pivot shaft 3. This causes the multi- .
articulated link mechanism o the ink supply device B attached .
to those yokes 4 to shift such that the lifting portions 37 of the rocking links 36 are brought into abutment engagement with the abutment pins 35 of the opening links 34. Since the pivot sha~ts 30 and 31 which are pivotally supported on the yokes 4 are moved downward with the yokes, a pair of operating links 38 which are supported pivotally on the side frames 8 of *he machine are moved rearwardly or to the right at their movable pins 39 and substantially upwardly at their movable pins 40. At the same time, the rocking links 36 are turned counterclockwise about the pivot shafts 31.
The rocking links 36 are made to slide rightwardly by guiding the pivot pins 22 for the support member 20 and ~he ink roller frame 10 in the horizo:~tal slots 44 of the guide links 43 while keeping the pivot pins 22 pushed to the upper ends of the vertical slots 41 of the rocking links 36 by the action of the springs 24 During this sliding operation, the main ink roller 16 rolls over the type suraces 6 of the , :
printing device 5, while being elastically held there, thus efecting the desired ink application.
Simultaneously with the first stage ink application~
the rocking links 36 are turned counterclockwise about the pivot shafts 31. As a result, the.lifting portions 37 at the ends of the rocking links 36 are brought into abutment against the abutment pins 35 o the opening links 34 ~Yhich are in engagement with the other opening links 45. The . ~ 9 ~
abutment impact of the li:Eting portions 37 upon the abut~ent pins 35 overcomes the actions of springs 46, thus further rocking the opening links 34 in the clockwise direction. As a result, the retaining projections of the opening links 34 are disengaged from the other opening links 45 so that both links 34 and 45 are brought into their released ~or lifted) conditions. Meanwhile, the opening links 34 are rocked . .
clockwise about the pivot shafts 30 while the other opening links 45 are moved counterclockwise about the movable pins 47. In accordance with these sequential operations, the auxiliary ink roller 18 applies ink to the type surfaces 6.
Meanwhile, the ink roller assembly A with the ink rollers l~ -and 18 passes over the platen 33 which is located below the -printing device 5.
Upon completion of the second stage ink application, :
the pivot pins 22 of the ink rollers are in abutment engagement , with the rearmost ends of the horizontal slots 44 of the ~ , guide links 43. ~hen the hand lever 2 is further gripped, the guide links 43 and the,rocking links 36 are rocked counterclockwise and the respective movable pins are moved until the in~ rollers are accommodated or housed in a center portion o the space defined by the side walls 8. The ink roller frame 10 with the two ink rollers 16 and 18 is stored .
in its inverted position inside of the label printing and applying machine at the back of ~he printing device 5.
Then, the regulating projections 48 formed on the opening links 34 abut against the dislocated connecting links 49 to stop further motion of the respective links. The link mechanism thus dislocated returns to its stationary condition of Fig. 1 upon release of the hand lever 2 after the printing device 5 has accomplished its printing operation upon the label 27 that has been delivered onto the platen 33.

,: : r 7~32 In the second embQdiment of ink roller assembly, shown in Figs. 6 and 7, elements that correspond to those in the first embodiment are correspondingly numbered with reference numerals that are raised by 100.
The ink roller frame 110 has a U-shaped cross-section. There is a main ink roller 11~ of a larger diameter and an auxiliary ink roller 118 of a smaller diamcter. Both of these ink rollers are impregnated with ink. They are rotatably mounted such that their respective roller shafts 117 and 119 are supported at the side walls llld of the ink roller frame 110. The side walls llld have engagement grooves 112, which extend longitudinally along the walls.
There are corresponding engagement projections 121 formed inside both side walls of the U-shaped support member 120.
The projections 121 are received in the engagement grooves 112 when the frame 110 is slide into the support member 120.
Outside both side walls of support member 120, there are respective longitudinally extending guide members 123 which project toward and past the open end of the U-shaped member ~0 120.
As seen in Figs. 6 and 7, there is a ~air of openable handleelements 113 which are attached to the center of the bridge wall llla of the ink roller frame 110 at pivot Pins 114. The handle elements 113 are made o~ a flexible material, such 2S a synthetic resin. Their feet have eccentric portions 113a formed on them, which are shaped to have a greater effective diameter when the handle elements are at their folded orientation. The handles 113 have retaiJlin~
projections 113b at their leading ends. These are bent in shape and reduced in thickness, 10~713~, The eccentric foot portions 113a are made openable or foldable down around the pivot pins 114, and these pins are mounted to a pair of attachment portions 115 protrudi from the bridge wall llla of thc ink roller frame 110.
Moreover, the eccentric foot portions 113d are made engageable with a recess lllb, which is formed in the bridge wall llla of the ink roller frame 110, Recess lllb has retaining ends lllc, The retaining projections 113b are sized and shaped to be snap fitted into the retaining notches 123a, which are formed in the pair of guide members 123 mounted to the support member 120.
When it is intended to attacll the ink roller assembly ~ of the second embodimellt to the support member 120 at the link mechanism of the ink supply device B, the paired handle elements 113 are raised inwardly to each other and into their upright positions, as shown in Fig. 6 and in broken lines in Fig. 7. Then, the upright handles 113 thus integrated are manually pinched together so that the engagement grooves 112 of the ink roller frame 110 may receive the ~
engagement projections 121 of the support member 120, thus ;
finishîng the attachment of the ink roller frame 110 to the support member 120 in smooth fashion. After that, the paired handles 113 are brought down and outwardly into their lowered positions, as shown in Fig. 7, so that their retaining projections 113b may be snapped again into the retaining notches 123a at the guide members 123 of tlle support memher 1~0. This snap action is aided by the flexibility of the handle elements 113.

97~3Z
While the handle elements 113 are pivoting downwardly, their eccentric foot portions 113a are $urned about their respective pivot pins 114 and in doing so, they pass over the retaining ends lllc of the frame 110 until they are snapped into engagement with the rece~s lllb. This locks the handle elemen*s 113 in their lowered, flat positions~
In case the ink supply in the ink rollers 116 or-llB is exhausted, or in case the lnk rollers themselves become unsuitable for further use due to wear, the ink roller assembly A as a whole is removed from the support member 120 of the link mechanism of the ink supply device B
and is replaced by another such assembly equipped with new ink rollers. During the removal of assembly A, the opposite ;
procedure to the attaching operation is followed. The paired handles 113 at the ink roller frame 110 are released from the retaining notches 123a of the guide members 123 and then are rotated to their raised positions so that they may permit and do not block extraction of the ink roller frame 110 .
As with the first embodiment of ink roller assembly~
the attachment and removal of the ink roller assembly A is accomplished with the labeling machine stationary in the condition of Fig. 1~ in which the support member of the link mechanism of the ink supply device B is in its protruding position at the ront end of the label printing and applying machine.
- At the outside of both side walls of the support member 120, a respective pivot pin 122 is formed. These are pivotally supported in connecting links 26 of the link mechanism of Fig. l. The paired guide members 123 are .. .. .. ....
~(~)97~3Z :
broùght into abutment engagement w;th rollers (not shown) that are located at the inside of guide links 43. Depending beneath the side walls of support member 120 are depending lugs each having a respective retaining hole 125 therein for receiving a spring 124. The other end of each spring is mounted on the respective pivot pin 122.
The use and function of the installed second - embodiment of ink roller assembly are the same as for the first embodiment.
As has been described above, the ink roller assembly according to the present invention is equipped with an ink roller frame which is removably attached to a support member that is attached to the leading or forward end of the link mechanism of an ink supply device. A pair of openable handles that are formed with a locking device are hinged to the ink roller frame such that they can be manually raised to unlock the ink roller assembly when that assembly is to be attached to or removed from the link mechanism.
When it is intende~ to ink the type surfaces, the ; 20 handles are locked in their lowered positions even during the turning motions of the ink supply rollers. Thus, ink supply -~
can be attained without inviting abutment of the ink roller frame against the platen which is disposed below the printing device. , Another advantage of the present invention is that ; -";~.
the ink roller assembly can be reliably retained in the support member of the link mechanism of the support member.
Furthermore, replacement of the ink roller assembly can be accomplished remarkably smoothly and without requiring that unnecessary pushing and extracting forces be applied. The invention also prevents the fingers of an operator from being stained Wit}l ink.
