A conventional ink roll includes a hub and a porous ink-receiving roll received by the hub, the hub having an axial through-hole for receiving a grooved shaft and extending into the through-hole. It is known that the lever is provided with a finger extending into the groove of the shaft (for example, in addition to the above-mentioned US patent specification, Utility Model Application Publication No. 5074 of 1942). This ink roll can be snapped onto a grooved shaft during installation, which has the advantage of simplifying installation.

However, in the above-mentioned ink roll, the fingers are snapped into the grooves on the shaft, so the fingers and the grooves on the shaft must match, and when the ink roll is inserted into the shaft, If you reverse the direction of the ink roll, you will not be able to get the snap lock function, and if you use it as is, the ink roll will come off.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an ink roll that can be reliably snapped onto a grooved shaft when replacing the ink roll.

In order to achieve this objective, according to the present invention,
Means is provided for being mounted on the hub beyond one end of the through-hole in the hub and in its extension so as to allow the ink-receiving roll to be installed in only one direction relative to the grooved shaft from the other end of the through-hole; The ink roll includes an extension part provided outside the hub near but apart from the finger, and the extension part extends to cover an opening at one end of the through hole. provided.

With this configuration, the ink roll is prohibited from being inserted into the shaft from the side where the extension is provided, and can only be attached from one direction. Therefore, even if the person replacing the ink roll is not an expert, the ink roll can be reliably snapped onto the shaft, and there will be no accident of the ink roll coming off during use.

Next, a detailed description will be given with reference to the accompanying drawings.

The embodiments of FIGS. 1, 3-6 and the embodiment of FIG. 7 are suitable for use with the composite label web 30 shown in detail in FIG. A composite web 30 of label material 31 is carried releasably attached to a support or backing material 32. The label material 31 is passed across the label material web to the composite web 3.
It is laterally separated by a lateral cut 33 extending over the lateral edges 34 and 35 of the 0.
Cuts 33, known as "butt cuts," separate the web 31 of label material into a series of end-to-end labels 36. The label material web 31 has a label material web 31 on its lower side.
It has a coating of pressure sensitive adhesive 37 firmly attached to it. Support web 32 has a thin film or coating (not shown) so that the label can be peeled from support web 32.

Groups 38 of cuts are equally spaced along the length of composite web 30. Each group of cutlets 38
extends through the support material as well as the label material. Each group of cuts consists of a cut 39 on the support.
It has an I-shape as a whole, consisting of S, 40S, 41S and linear cuts 39L, 40L, 41L on the label material. The portion of the web 32 between one end of the cut 39S and the cut 40S provides a frangible portion 43S, and the portion of the web 32 between the other end of the cut 39S and the cut 41S provides a frangible portion 42S. Similarly, the label material portion between one end of the cut 39L and the cut 40L is a fragile portion 4.
3L and the other end of cut 39L and cut 41L
The label material portion between the two provides a frangible portion 42L.

Referring to the embodiments of FIGS. 1 and 3-6, there is shown a label printing and application apparatus, generally designated 50. Referring to FIGS. Device 50 has a frame, generally designated 51, including a frame section 52 and a frame section 53 to which a cover section is removably connected. A subframe 55 made of a single rigid sheet of metal is suitable for being fastened to the frame section 52, for example with screws 56. The screws 56 pass through respective holes 57 in the subframe and into respective bosses 5 of the frame section 52.
8 is screwed together. The frame 51 consists partly of the handle portion 60 of the frame section 52 and partly of the frame section 54. There is a handle indicated generally at 59. Sections 53 and 54 are housing section 52
The frame section 52 is connected to the frame section 52 by a snap-on coupling that includes a snap-on flexible resilient member 61 that can be engaged in a notched groove 62 of the frame section 52 .

The subframe 55 includes a print head generally indicated at 63, a feed wheel 64, a ratchet wheel 65 (FIG. 3) formed integrally with the feed wheel 64, and a gear or gear formed integrally with a lever 67. part 66, an applicator 68 in the form of a roll, a guide 69' integral with the platen 69, a peeler 70 provided at the edge of the platen 69, rollers 71 and 72, a post or stud 73, a post or stud 74. , post or stud 75 , stripping board 76
A guide 77 integrally formed with this is installed. Handle portion 60 and frame section 54 have pivots 78 mounted on respective bosses 79 and 80. The pivot pivotably mounts an actuator 81, which is shown in the form of a lever. When the user grasps the handle 59 (assuming the user grasps the handle 59 with the right hand), the thumb passes around the frame section 54 and the actuator 81 engages the user's finger. Actuator 81 supports a gear or gear portion 82 that meshes with gear 66 . A spring assembly 82', including a compression spring 83, urges the handle portion 60 and the actuator 81, forcing the actuator 81 in a counterclockwise direction (FIGS. 1 and 3). Spring assembly 82' is shown in detail in FIGS. 45-48 of U.S. Pat. No. 3,968,745.
Actuator 81 and gear 82 are initially in the position shown in solid lines in FIG. 3, but when operated they move to the position shown in dotted lines 81'. Feed wheel 64, pawl wheel 65,
Gear 66 is coaxially mounted on post 74. Gear 66 has a pawl 83 that meshes with ratchet wheel 65 . When the actuator 81 moves from the solid line position to the dotted line position in FIG. 3, the gear 66 rotates counterclockwise until the pawl 83 passes the teeth 84 of the ratchet wheel 65, and when the actuator 81 is released, Spring assembly 82' drives gear 66 clockwise, causing pawl 8
3 drives the feed wheel 64 clockwise. Pawl wheel 6
5. Clockwise rotation of the feed wheel 64 is therefore prevented by a flexible, resilient pawl 84' which meshes with the ratchet wheel 65.

Lever 67 is in a plane offset from the plate of gear 66. As best seen in FIG. 1, a lateral portion 85 connects gear 66 and lever 67 together. This lateral portion 85 passes through an arcuate slot 86' in the subframe 55. Lever 67 is connected to printhead 63 by a pin type connector, generally indicated at 86. The pin coupler 86 is a pin and slot coupler consisting of an elongated slot 87 in the lever 67 and a pin 88 having a roller 89 received in the slot 87. Washer 90 and clip 91 connect roller 89 to pin 8.
It is held at 8. Pin 88 is print head 6
It is fixed at 3. As best shown in FIGS. 1 and 4, printhead 63 is provided with a pair of elongated parallel ball tracks 92 and 93. The subframe 55 has a pair of ball orbits 9
4 and 95 are installed. Rows of ball bearings 96 and 97 are received in respective ball tracks 92 and 94 and 93 and 95. This ball bearing array is the first of U.S. Pat. No. 3,968,745.
This is shown in detail in FIGS. 2 and 24. The ball tracks 92-95 form a track structure that allows the printhead to reciprocate toward and away from the platen 69. Ball track 95 is installed so that it can move relative to ball track 93. Compression spring 95' forces ball track 95 towards ball track 93 and compensates for the gap between ball tracks 93 and 95.

The device 50 is known as a two-line machine.
A device is provided having two series L ₁ and L ₂ of print swaths 98 and 99 that can be selectively set. Band 98 of series L ₁ can be selectively set by manual operation of knob 100 , and band 99 of series L ₂ can be selectively set by manual operation of knob 101 . Knobs 100 and 101 project through openings 53' in cover section 53.

A die roll 64a with a groove 64b through which the teeth 64' of the feed wheel 64 pass is rotatably mounted on the arm 64c. The arm 64c is installed on the post 73. Arm 64c has an integral side tab 64g that extends through slot 64f in subframe 55. A tension spring 64d is attached to a post 64e fixed to the subframe 55 and a tab 6.
Connected to 4g. Spring 64d presses die roll 64a against feed wheel 64. As the feed wheel 64 rotates, the teeth 64' of the feed wheel 64 cooperate with the die roll 64a to break the frangible portions 42S and 43S of the support web 32 and create perforations in the support web 32.

The ink mechanism 102 includes an arm 103 rotatably mounted on a pivot 104 fixed to the subframe 55. A retainer 105 holds arm 103 on pivot 104. The arm 103 supports a laterally extending small diameter pin 106 on which an ink roll 107 according to the invention is installed. Pin 106 extends through an arcuate slot 108 in subframe 55. Tension spring 109 acts at one end on a side tab 110 supported by arm 103 and at its other end on a pin 111 fixed to print head 63. Tab 110 and pin 111
The position of is chosen so that there is no substantial stretching or expansion of spring 109 as print head 63 moves from the solid line position to the dotted line (print) position indicated by dotted line 63' during the printing stroke. Similarly, as printhead 63 moves between these positions during the return stroke, there is no substantial stretching or expansion of spring 109. The position of the pivot 104 is such that during the printing process it pushes the ink roll 107 from the solid line position to the dotted line position indicated by the dotted line 107', and during the return stroke of the print head 63 the ink roll 107 returns to the solid line position. . Additionally, the force of spring 109 forces ball trajectory 92 toward ball trajectory 94 to compensate for the gap.

The composite label web in roll form has a circular cylindrical core 112 of cardboard or other suitable material. The boss 113, made of plastic or other suitable material, has three flexible, resilient sections 114 to which the core can be snapped onto and to allow easy removal of the core 112 from used rolls. There is. Boss 113 is post 7
5 and is rotatably mounted on the clip 113'.
is held by.

Referring to FIGS. 5 and 6, there are generally V-shaped transverse grooves 115 equally spaced around the periphery of the feed wheel 64. These grooves 115 greatly reduce the contact area that the support web 32 makes with the feed wheel 64. This is the supporting material web 32
The tendency of the upper viscous rubber to be transferred to the feed wheel 64 is minimized. The viscous rubber on the feed wheel 64 also causes problems in the feeding of the composite web 30. The land 116 on the outer periphery of the feed wheel 64 is about one-fifth of the pitch distance d, and therefore the groove 115
is 80 when the feed wheel has a continuous, smooth circumference.
% also reduces the contact area.

To load apparatus 50, cover section 53 is removed and a composite label web supply roll is placed onto boss 113. Die roll 64a and its arm 64b are moved to an over-center position. When the actuator 81 is partially moved toward the position indicated by the dotted line in FIG. Composite web 32
The free end of passes partially around the bottom of the roller 71, over the platen 69, around the peeler 70,
It goes partly under the platen 69 and under the rollers 71, partly around the rollers 72, partly over the feed wheel 64, and passes over the peeling plate 76 and the guide 77. When actuator 81 is released, brake roll 117 contacts the end of printhead 63 and presses web 30 while applying label 36.
Brake roll 117 to prevent the
presses the web 30 against the plate 118. Die roll. 64a and its arm 64b can be moved to the position shown in FIG. 3 and cover section 53 snapped into place.

When it is desired to print and apply a label 36, a squeeze on actuator 81 initiates a print and feed cycle, causing gear 82 to drive gear 66 and actuate lever 67. Pivoting of lever 67 drives the printhead into a position for cooperation with the platen to print data on label 36. Actuator 8
1 is released, the pawl 83 drives the feed wheel 64 in such a way that the just printed label 36 is fed into the labeling position relative to the applicator 68, while in this position the trailing edge of the label 36 is still supported. It is attached to the material web 32. Also, the next consecutive label 36
is placed correctly on platen 69 to be printed during the next print cycle.

In the specific example of Fig. 7, Fig. 1 and Figs.
Parts that are functionally equivalent to those shown in the illustrated embodiment have been given the same reference numerals. Referring to FIG. 7, actuator 81 supports pivot 130. Referring to FIG. A link 131 is pivotally attached to pivot 130. A pivot 132 supported by the link 131 connects the link 131 and the lever 133. The lever 133 is rotatably installed on the post 74. Lever 13
3 has a pawl 134 which has the same function as pawl 83 in FIG. Circular hole 13 of lever 133
A pivot 135 is provided on the pin coupler 86 which extends through the printhead 63 and is secured to the printhead 63. Instead of having the track structure of the embodiments of FIGS. 1 and 3-6, the subframe 55 of the embodiment of FIG. 7 has a track structure with elongated slots 137. , a pin 138 on which rollers 139 are installed. Roller 139 is received in slot 137.
As lever 133 moves, pin 135 makes a slight arc, so the right end of print head 63 also makes a slight arc. The left end of the print head 63 is the roller 1
39 moves in a straight line, so it essentially makes a reciprocating motion. When the print head 63 is in the printing position,
Pivot 135 is in the position shown by dotted line 135', in which print head 63 is perpendicular to platen 69. When actuator 81 is released, the spring assembly of FIG. 1 causes actuator 81 to pivot counterclockwise, thereby driving lever 133 clockwise to move printhead 63 as shown in FIG. At the same time pawl 134 drives the feed wheel to advance composite web 30 a distance equal to the length of label 36. In the embodiment of FIG. 7, gear 82 has been removed from actuator 81.

The devices of FIGS. 1, 3-6, and 7 are constructed primarily of molded plastic material. Preferably, the subframe 55 is made of steel. actuator 81, gear 66 and lever 67, ratchet and feed wheels 65 and 64, most of printhead 63, sections 52, 53, 54;
Boss 113 and tracks 94, 95 are made of a suitable molded plastic material. Referring to Figure 7,
Link 131 and lever 133 are also made of plastic material.

In fact, in some cases, after removal of the label, a small amount of pressure-sensitive deposits of viscous rubber are deposited on the support web 3.
2 remains on top. In this case, when the support web comes into contact with the feed wheel 64, this viscous rubber material may be transferred to the feed wheel, impeding efficient operation during continued use of the device.

The feed wheel 64 is treated with a non-stick or resistant coating 116' sufficient to substantially prevent the transfer of viscous rubber or pressure sensitive adhesive on the support web 32 to the feed wheel. There is a web contacting surface 116. The web contact surface of the feeding wheel is covered with a pressure sensitive tape of 7.5 gw/cm ² for 2 to 5 seconds.
Pressure sensitive tape (e.g. 3M transparent tape)
5910) is preferably easily released.

metal, or polyacetyl resin (e.g. Delrin), polycarbonate resin (e.g. Lexan),
Phenyline oxides (e.g. Noryl), nylons (e.g. NylaFil, Zytel, Nylatron),
A particularly preferred method of increasing the separation properties of feed wheels made of acrylonitrile, butadiene styrene resins (e.g., cycloac-ABS resins), unsaturated polyester molding resins, and other organic polymeric plastic materials is to contact the support web of the feed wheel. Applying to the surface an adhesive continuous coating of a resinous coating composition having a lower surface energy than the base polymeric material of which the vehicle is made.
Preferred coating compositions include compositions based on materials such as moisture-cured all-silicone resins used in aircraft manufacturing and protective overcoat retention, and for making release papers for pressure sensitive adhesive compositions. Solvent based paper curing is based on silicone polymers used in
curable) coating composition. The coating must have sufficient adhesion to the feed wheel to prevent it from peeling off during use, so the surface to be coated must be etched or otherwise slightly roughened before the coating is applied and cured. It is desirable to do so.

This preferred method involves incorporating a lubricant into the feed wheel while it is being molded in accordance with U.S. Pat. It is distinguished from those with means for providing separation properties by treatment, and also from the method of applying a liquid lubricant to the feed wheel for this purpose according to US Pat. No. 3,968,745. Although these other methods are also advantageous,
The preferred method described above is more effective over long periods of time.

Referring to FIGS. 8 and 10 through 36, a label printing and application apparatus, generally designated 150, is illustrated. The device 150 is
It has a frame generally designated 151, which frame includes a housing section 15.
2,153,154 and a subframe consisting of a single rigid metal frame plate 155. The housing is essentially closed. The frame 151 is partly a handle part 160 and partly a frame part 154.
, having a handle indicated generally at 159. Housing section 154
is attached to the housing 152 by a screw 161 that is screwed into a threaded hole 162. Frame section 154 is located in front of lip 168 of section 154 and projection 164 of section 153 extends behind wall 165. Section 153 is connected to section 152 by a snap-fit connector that includes a flexible, resilient member 166, typically snap-shaped, that fits into a groove 167 drilled below section 152. Also,
Section 153 has installation studs 1 secured in corresponding grooves 169 of section 152.
68 is provided.

The print head 17 is mounted on the frame plate 155.
0, feed wheel 171, gear or gear section 172, applicator 173 shown in the form of a roll, platen 1
74, peeler 175, installation pin 176 and multiple rollers 177, installation posts 178, 179, 18
0,181, and a support 236 are installed.

Frame plate 155 has two precisely spaced square holes 182 for receiving mating square mounting pins or studs 183. The holes 182 extend at right angles to each other such that the two opposing sides of each stud contact the corresponding long sides of the corresponding rectangular hole 182. pin 18
3 cooperates with the corresponding holes 182 to accurately position the frame plate 155 relative to the housing section 152. Although only one is shown in detail in FIG. 31, there are three equivalent mounting couplings that secure frame plate 155 to housing section 152. Frame plate 155 has three large holes or cutouts 184. Housing section 152 has a pin or stud 185 extending through a cutout 184. Referring to FIG. 31, a retainer 186 in the form of a grip ring grips the stud 185. A compression spring 187 fastened around the stud 185 is
It is in contact with the frame plate 155 and the retainer 186. With age and continued use of the device, the studs tend to elongate. Panel 187 is board 185
is held firmly against housing section 152 at all times. Stud bolt 18
Since the diameter of 5 is considerably smaller than the cutout 184,
The position of frame plate 155 relative to housing section 152 is such that pin 1 in each slot 182
83.

Frame plate 155 has a pair of elongated notches or open-ended slots 188 and a pair of opposed elongated notches or open-ended slots 189. Slots 188 and 189 are connected to larger respective notches 190 and 191. Opposing ball tracks 192 and 193 are received in respective notches 190 and 191. The print head 170 has a pair of opposing ball tracks 195.
and 196 printhead frame 19
Consists of 4. Ball bearing row 197 is placed in a pair of ball bearing tracks 192 and 195, and ball bearing row 198 is placed in a pair of ball bearing tracks 193 and 196. Ball trajectories 192 and 193 are generally of channel type construction. Ball trajectories 192 and 193 are the first
In the position shown in Figures 0 and 11,
Ball tracks 192 and 193 are received in frame plate 155. A threaded fastener 199 extends through the notch 188 and is threaded into a hole 199' in the ball track 192. Similarly, a threaded fastener 200 extends through the notch 189 and is threaded into a hole 200' in the ball track 193. The print head 170 has two series of print swaths, as shown in detail in FIG. 31 of US Pat. No. 3,968,745, so that the print head 170 can print two series of data. It is important to the printing quality that the print head 170 moves relative to the platen 174 so that the characters on the print swath 201 uniformly contact the label 207 on the platen. If print head 170 is
4, some of the selected characters will print and others will not print at all or only slightly. Because the notches 188 and 189 are larger than the diameter of the fasteners 199 and 200 that they pass through, the ball tracks 192 and 193 can be placed in the correct position during device manufacture, thereby allowing the print head 170 to Accurate alignment with platen 174 allows for minimal clearance between the ball tracks and the corresponding ball bearing rows. Printhead frame 194 and integrally molded ball tracks 195 and 196, as well as ball tracks 192 and 193, are made of plastic material. The balls of ball rows 197 and 198 are made of a hard material, such as steel, as shown in FIGS. 12 and 24 of U.S. Pat. No. 3,968,745. As shown schematically in FIGS. 21-23, the typeface 202 extends parallel to the platen 174. Since ball trajectories 192 through 195 are all straight, printhead 170 is forced to move in a straight line. Therefore, print head 170 must move perpendicular to platen 174 for good printing. Therefore, to ensure accurate alignment of print head 170 and platen 174, during manufacturing or even subsequently,
Means are provided so that the movement of the print head into the position of printing the composite web onto the label can be adjusted.

Apparatus 150 utilizes composite web 203. The composite web 203 of the label material 204 is
It is releasably adhered to support backing material 205. The label material 204 is a label material web 2
The label material 204 is cut transversely with bar-like cuts or slits 206 extending the full width across the label material 204, thereby separating the label material 204 into end-to-end rows of double-ended labels 207. Composite web 2
03 is wrapped around a circular cylindrical core 208 made of cardboard or other suitable material. The roll of composite web is mounted on a reel generally designated 209. Reel 209 consists of a generally flat disk 210 with a hole 211 in the center. Disk 210
has a plurality of equally spaced pins 212 equidistant from the central hole. When the disc 210 is molded by an injection molding machine, the disc 210, the hole 211, and the integral pin 212 are created. Reel 209 also includes a boss, indicated generally at 213. Boss 213 has a central tubular boss portion connected to end wall 215. Pin 212 is received in mating hole 212' in the end wall, thereby keying disk 210 and boss 213 to rotate together as a single unit. A plurality of flexible, resilient cantilevers are mounted on finger 216 that extend outwardly from boss portion 214 and are integrally connected to end wall 215 . When the wick 208 is placed over it, the fingers 216 flare out slightly and move away from each other. At the free end of finger 216 there is a projection 217. Each protrusion 217 has a pair of angled surfaces 218 and 219. Surface 218 serves to load the label roll onto boss 213, surface 219 helps to prevent the roll from being accidentally dislodged from boss 213, but prevents the roll from being accidentally dislodged from boss 213.
8 is curved so that the user can easily remove it. The fingers 216 bend inward when the supply roll is loaded onto the reel 209 and when the spent core 208 is removed. The post or shaft 181 is connected to the hole 211 of the disk 210 and the boss portion 21
4 through the inner diameter 220. A retainer 221 received at the end of the shaft 181 is attached to the reel 20
9 from becoming dislodged from the post or shaft 181 and preventing the boss 213 from separating from the disc 210 and preventing the pin 212 from coming into play with the hole 212'. Boss 213 is also injection molded. Disc 2
10 defines one edge of the feed path so that composite web 203 emerging from the roll is accurately aligned with platen 174 and feed wheel 171 to start.

The actuator, indicated generally at 222, is in the form of a pivotably operated lever mounted on a support structure, indicated generally at 222S, which includes a pivot pin 223 received in an eccentric 224 in the form of a sleeve. There is. Spring assembly 225, shown in detail in Figures 45-48, forces actuator 222 in a counterclockwise direction (Figures 8 and 10). Briefly, the spring assembly includes a compression spring 226.

The actuator 222 comprises a gear or gear portion 227 having an opening 228 formed by toothing. The gear portion 227 meshes with the gear portion 229 of the gear 172. Gear portion 229 has one large tooth 230 that meshes with a tooth adjacent to gap 228 . Since the teeth 230 only fit with the apertures 228, the actuator 222 can be assembled in the correct relative position with respect to the gear 172. Gear 172 has a gear portion 231 that meshes with a gear portion or rack 232 integrally formed on printhead frame 194. Gear portion 231 has an opening 233 formed by removing a tooth, and gear portion 232 has an opening 233 that is received in opening 233 so that print head 170 is only assembled in the correct relative position relative to gear 172. There is one large tooth 234. Assuming that the handle 159 is grasped by the user's hand, the user's fingers can manipulate the actuator to pivot the actuator 222 clockwise against the force of the spring 226 of the spring device 225 ( 8 and 10), thereby gear 1
72 counterclockwise and drive printhead 170 into a printing position in which it cooperates with label 207 in overlapping relationship with platen 174. When actuator 222 is released, spring 226 similarly returns actuator 222 gear 172, printhead 170, and other parts described below to their initial positions. Sections 152 and 154 are stop 1
It has 51'.

The drive shaft 235 is molded integrally with the gear 172. Support 23 in the form of a tube or tubular bearing
6 is suitably secured in hole 237 in frame plate 155, as best shown in FIG. As will be described in more detail later, the feed car 171
has a plurality of pairs of laterally spaced teeth 171' that engage support web 205. 21st
Teeth 171', shown exaggerated in the figure, are tilted forward to grip the feed edge of web 205. The feed wheel 171 includes a rim 238 to which teeth 171' are integrally connected. The rim 238 has an annular outer periphery and the section that engages the web is the bead 23.
8' and a central space or gap with an annular section 238' having a smaller diameter than section 238. As shown in Figure 36,
Section 238' has land 116a ;
This consists of fairly sharp peaks to provide essentially a line contact between web 205 and land 116a . The gaps in the form of grooves 115a between lands 116a and sections 238'' reduce the contact area that would otherwise consist of the surface area of feed wheel 171 to a very small percentage of the circumferential area, i.e. Reduce by less than 50%, preferably less than 10% as shown. Feed Car 1
Sticky matter, viscous rubber, etc. that adhere to the land 71 are collected in the gap 115a , so that the outer diameter of the feed wheel 171 defined by the land 116a does not increase. An increase in diameter has the disadvantage of increasing the length of web that feed wheel 171 advances when the actuator is actuated. For example, gap 115
The depth of a is approximately 0.63 mm (0.025 inch) and each section 238' has 190 lands 116a . Land 116a is characterized by its sharpness,
Web 205 is not cut. Feed is tooth 17

At least only its outer periphery is made of plastic material, which has an inherently low coefficient of friction. In addition, the outer circumferential surface of the feed wheel 171 may be overcoated with a liquid or permanent coating material to prevent the build-up of adhesives, viscous rubber, etc., and to incorporate a suitable lubricant into the plastic material from which the feed wheel 171 is molded. is preferable. An annular wall 239 connects the rim 238 and the boss portion 240. Boss portion 240 has a bore portion 241 that is recessed into a large bore portion 242 . The bore portion 242 is provided with a number of axially extending grooves and protrusions comprising ridges or grooves 244 . A rolling contact one-way clutch 243 is received in bore portion 242. The initial inner diameter of the bore portion 242 is defined by the crest of the protrusion. That is, the mountain 244 is the clutch 2
It is smaller than the outer diameter of 43. By forcing the clutch 243 into the bore portion 242, the clutch 2
43 is assembled in the feeding wheel 171, and the mountain 244
holds the clutch 243 in the position shown in FIG. 18 with a slight frictional force. Clutch 243 has a plurality of rollers 245 in contact with an outer circular cylindrical surface 246 of support 236. The unidirectional clutch 243 acts as a bearing to allow clockwise rotation of the feed wheel, but prevents counterclockwise movement, as shown in FIGS. 8 and 17. For example, specific examples of clutches useful in the present invention include
06710. There is one called a roller clutch made by Torrington Co., Torrington, catalog number RC-081208, described in the 1969 catalog RC-6.

A portion of clutch 243 is shown in FIGS. 19 and 20. In the position shown in Figure 19,
Since the rollers 245 are in wedge contact with their respective inclined surfaces 247, the clutch 243 prevents the feed wheel 171 from turning counterclockwise;
On the other hand, in FIG. 20, feed wheel 171 is shown rotating in the direction of arrow A, with roller 245 being unsecured between surfaces 247 and 246. clutch 24
3 is spring loaded, and a spring, shown schematically at 248, constantly presses roller 245 against both surfaces 246 and 247. This causes the clutch 243
The backlash is negligible, and the backlash is considerably reduced compared to when using a pawl such as pawl 248. The feed wheel 171 includes a rim 238, a wall 239,
It includes a web 249 to which a boss 240 is connected. The inner periphery of the rims 238 and 238 on one side of the wall 239 has a plurality of grooves 250 and ridges 251 arranged in an annular manner. Grooves 250 and ridges 251 extend in the axial direction. A ratchet wheel, generally designated 252, has a plurality of pawl teeth 253. tooth 2
53 is integrally formed on one side of the wall 254. An annular wall or flange 255 with a plurality of equally spaced openings 256 has a plurality of grooves 257 and ridges 25
I have 8. Groove 250, mountain 251 and groove 2
57 and mountain 258 have the same pitch and interpolate with each other. The ratchet wheel 252 also has an internal bore 260
It has an annular boss 259. Support 236 extends within bore 260 to a location where the end of boss 259 abuts one end of clutch 243. At this position, the ridge 258 of the ratchet wheel 252 and the groove 2
57 are received in corresponding grooves 250 and ridges 251 of feed wheel 171 which interpolate with each other.
Moving the ratchet wheel from its assembled position to the position shown in FIG. 18 selectively changes the position of ratchet wheel 252 relative to feed wheel 171. Such changes occur in print head 170 and platen 174.
The alignment of the label 207 in the printing area between is changed to a position where the web 205 and the preceding label 207 are advanced relative to the peeler 175. The mechanism by which this is accomplished is described in U.S. Pat.
It is partially the same as that described in No. 3783083.

Groove 2 cooperates with the corresponding peak 258 and groove 257.

is constructed from molded plastic material. Split boss 263 has internal bore 26 with flat portion 267 received by flat portion 262 of shaft 235.
It has 6. A clamp 268 is received around boss 263. The pawl structure 264 is attached to the axis 2
35, the clamp 268 applies a compressive force to the split boss 263 in order to firmly but removably install it. Due to the cooperation of flats 262 and 267 and because drive shaft 235 is made integral with gear 232, pawl structure 264 and gear 172 rotate together. The actuator 222 is
When pivoted clockwise, as shown in FIGS. 8 and 10, the gear 172
rotates counterclockwise. The counterclockwise rotation of gear 172 rotates the pawl structure counterclockwise, thereby bringing pawl 265 into driving relationship with the next successive tooth 253. Actuator 222
Upon release of , return spring 226 rotates gear 172 and pawl structure 264 clockwise. Accordingly, the drive end 269 of the pawl 265 is connected to the pawl wheel 252.
The feed wheel 171 is turned clockwise to advance the composite web 203.

Referring to FIGS. 21-23, a brake mechanism, designated generally at 270, is illustrated. The brake mechanism 270 includes the brake member 2
71 and an arm 272 integrally connected to a boss 273. The boss 273 is pivotably mounted on a stud 273' fixed to the frame plate 155. Brake member 271 includes a flexible resilient brake shoe 274 for applying a braking force to composite web 203. Tension spring 275 (FIGS. 8 and 11) is connected at one end to a folded tab 276 of frame plate 155 and at the other end to a post 277 formed integrally with brake member 271. As shown in FIG. 11, posts 277 extend through arcuate slots 278 in frame plate 155, and springs 275 connect posts 277 and tabs 276 on the front side of frame plate 155. The tab 276 and post 277 are connected to the spring 2

As shown in FIG. 21, since the axis of the shaft 291 is located at a position where the arm 286 is counterclockwise with respect to the position shown in FIG. 22, the brake member 283 is in its non-effective position. It is in. When shaft 291 is moved to the position shown in FIGS. 22 and 23, arm 286 moves clockwise, thereby bringing brake member 283 into its effective position. Referring to FIG. 23, due to the inclination of the brake member 271 and the position of the brake shoe 274 relative to the brake shoe 284, the brake 274
70 is self-energizing. Therefore, when the label 207 is pasted, the peeler 17
The pulling force that the label was exerting on web 203 upstream of 5 causes brake 270 to exert an even greater braking force on web 203.

Axis 291 carries a roll, generally designated 293, consisting of roll member 294 on one side of slider 288 and roll member 295 on the opposite side of the slider. Further, the shaft 291 is connected to the gear 17

Referring to FIG. 10, the user can
It will be apparent that the slider 288 can be moved to the position shown by exerting a force to the left of the slider 288. Roll 293, guide 300, arm 302 supported thereon, associated arm 286, and brake member 283 are moved to the position shown in FIG. No, spring 3
04 (FIG. 21) holds these components in position for easy loading of the device 150. As can be seen in FIG. 10, shaft 291 is at one end of slot 296 in arm 297. Assuming that the label feeder is threaded onto the device, the first movement of actuator 222 causes arm 297 acting on shaft 291 to pivot arm 302 counterclockwise (FIG. 10) and Tsute roll 2
93 is returned to cooperation with support web 203 and feed wheel 171, guide 300 is moved into guiding relationship with the side edge of web 203, and brake member 28
3 is moved to the effective position shown in FIG. Subsequent operation of the actuator causes arm 297 to move to axis 2
91, but because of the slot 296, the arm 297 has no effect on the shaft 291. Slider 288 and components operatively associated therewith can also be moved from the position shown in FIGS. 10 and 21 by pushing projection 288' to the right, as shown in FIG. It may also be possible to return it to the position shown in Figure 23.

The composite web 203 comes into contact with it through an elastic device 310 in the form of a bent leaf spring from where it is pulled out of the roll. As feed wheel 171 advances composite web 203, elastic device 310 flexes, and device 310 gradually returns as excess web 203 emerges from the supply roll after brake 270 is applied. The track structure, indicated generally at 311, includes guide track sections 312,

From region Z1, the composite web passes partially around a roll, generally designated 323, consisting of a plurality of rollers 177, for example three. Rollers 177 freely rotate around post 176. Since multiple rollers 177 are provided, they do not tend to stick to the post 176 as they would if only one long roll (not shown) were provided. After composite web 203 passes around roll 323, labels 207 on composite web 203 are attached to platen 174 and print head 1.
It is located between 70 and 70. Figure 10 shows label 207
One of them is shown almost completely peeling off from support web 205 and about to be applied by applicator 173. The applicator 173 is
Although shown as comprising a roll rotatably mounted on a post 325 secured to frame plate 155, other types of applicators may be substituted if desired. In the filling position of FIG. 10, composite web 203 passes partly around the end of slider 288, partly around roll 293, and then partly around feed wheel 171. The shaft 178 has a roller 327 (FIG. 8) between the boss 285 and the frame plate 155, and a slider 288.
