Both ends of 3a are fitted to cylindrical bearings 1h, 2b formed on the outer walls 1, 2, and the hook 23b is fitted to the shaft 9. The configuration of the guide members 24 and 25 will be described with reference to FIG. The guide member 24 is rotatably attached to the shaft 4, and the guide member 25 is rotatably attached to a shaft portion 1 i erected on the outer wall 1. In both cases, a hole formed in the guide member 25 is fitted to a shaft portion 24a provided in the guide member 24, and the posture is maintained as shown in FIG. The guide member 24 has two guide portions 24b and 24c for the purpose described later. The guide member 24 has a beak-shaped tip portion 24 d formed in a groove 18 b formed on the peripheral surface of the transfer drum 18.
Has been inserted. In addition, since the two grooves 18b are formed as described above, two tip portions 24d are actually formed, but in FIG. 2, since they overlap, it is as if there is only one. It is drawn as follows.

Next, the configuration of the printing mechanism will be described.
The printing mechanism can be divided into an ink roller mechanism and a printing device. The ink roller mechanism according to this embodiment includes an ink arm 26 rotatably attached to a shaft 2c provided on the outer wall 2, and a rotatable shaft 26a provided at the tip of the ink arm 26. And an ink roller 27 attached thereto.

The ink arm 26 is given a clockwise rotation behavior by a spring (not shown).
FIG. 1 shows a state in which the rotation is prevented by a stopper (not shown). On the other hand, the ink roller 27 is composed of a bobbin-shaped frame made of synthetic resin and a flexible ink impregnated body attached to the frame. In FIG. 1, both ends facing the outer walls 1 and 2 are shown in FIG. The outer diameter of the collar 27a of the frame formed in the portion and the outer diameter of the roll-shaped ink impregnated body 27b are shown.

The two arms 10c, 1 of the manual lever 10
The printer P is attached between 0d. The way of attachment is as follows.
0i, and screwed into a female screw (not shown) formed on the printing device P. The configuration of the printing device P will be described in detail with reference to FIGS. 10, 11, and 12.
FIG. 10 is a sectional view of the printing device P shown in FIG. 1 as viewed from the left. The casing of the printer P is formed by
The two side plates 30 and 31, the top plate 32, and the cradle 33. In addition, a member or the like serving as a beam is provided between the two side plates 30 and 31 in practice, but is omitted because it is well known. The two side plates 30 and 31 are provided with circular holes having substantially the same size at opposing positions so as to bear a sleeve described later. Side plate 3
The 0 circular hole is closed by the cover 34, but this has no technical significance. A hole 31a is formed in the side plate 31 for the purpose to be described later, and a window 32a is formed in the top plate 32.

A sleeve 35 having a cylindrical shape as a whole is rotatably fitted in a circular hole provided at a position facing the side plates 30 and 31, and a set shaft 3 is provided inside the sleeve 35.
6 is rotatably fitted by the operation knob 37. The set shaft 36 has six grooves 36a formed in a ring shape on the peripheral surface. The sleeve 35 is shown in FIG.
Slits 35a, 35b extending in the axial direction at the upper and lower positions
At the left end positions, holes larger than the widths of the slits are continuously provided. Then, the distal end of an elastic stopper member 38 as shown in FIG. 11 penetrates these large holes, and is inserted into the leftmost groove 36a in FIG. Thereby, the stop member 3
8 serves to prevent the sleeve 35 from coming off,
As will be understood from the following description, a click action is performed on the movement of the set shaft 36 in the axial direction.
A moderation mechanism is configured together with the groove 36a.

In FIG. 10, an annular portion 35c is formed at the right end of the sleeve 35. As shown in FIG. 12, the annular portion 35c has 16
Individual recesses are formed. A stop member 39 having two elastic portions is attached to the shaft portion 30a erected on the side plate 30, and the distal end of the arm portion is pressed against the peripheral surface of the ring portion 35c. . 10 and FIG.
As can be seen from FIG. 2, a pin 40 is press-fitted into the set shaft 36. The pin 40 passes through the slits 35a and 35b of the sleeve 35. Therefore, when the set shaft 36 is rotated by the operation knob 37, the pin 40 and the sleeve 35 rotate together. Therefore, the above-mentioned annular portion 35c and the stop member 39 constitute a moderation mechanism for regulating the rotational position of the set shaft 36.

As can be seen from FIG. 10, six set wheels 41 are rotatably mounted around the sleeve 35, and a print belt 42 is hung on each of the set wheels 41. Since the relationship between the set wheel 41 and the printing belt 42 is the same for each pair, one of the pairs is shown in FIG.
This will be described with reference to FIG. The set wheel 41 is made of synthetic resin, and has a protruding piece 41a formed on an outer peripheral portion and 16 cut grooves 41b formed on an inner peripheral portion. Also, this kerf 41b
, The tip of the pin 40 is fitted. The number of the cut grooves 41b is the same as the number of the concave portions of the ring-shaped portion 35c, and the angular positions of the cut grooves 41b and the concave portions match due to the above-described coupling relationship.

The printing belt 42 is not in the shape of a ring, but is in the form of a string by itself, and both ends thereof are inserted into L-shaped grooves formed on both sides of the protruding piece 41a, as is well known. , So that it does not come off during use. The printing belt 42 is hung on the receiving table 33 in the assembled state. At this time, since the printing belt 42 is bent at a predetermined angle by the receiving table 33, the set wheel 41 cannot be easily rotated by the frictional force therebetween. Further, although symbols such as numerals are attached to the peripheral surface of the printing belt 42, as is well known, half of them are symbols for printing, and the other half are symbols for finding. At the time of printing, a necessary printing symbol is
Will be arranged below.

On the other hand, as shown in FIG.
Has an indicator 43 attached thereto. The attachment is rotatable with respect to the set shaft 36, but when the set shaft 36 moves in the axial direction, it moves together. The indicator 43 is connected to the side plate 31.
Window 32a and six printing belts 4
2 and an index 43a is formed at the tip.

The printing device P has such a configuration, but when the necessary printing symbols are aligned below the receiving table 33, the following operation is performed. The setting operation is performed by the operation knob 37, and the confirmation is visually performed from the window 32a. First, a printing belt 42 whose symbol is to be changed is selected. In that case, the operating knob 37 is operated left and right in FIG. In FIG. 10, the pin 40 is fitted in the cut groove 41b of the set wheel 42 located at the rightmost position, and the index 43a is on the print belt 42 located at the rightmost position. Therefore, this state is a state in which the symbol of the print belt 42 located on the rightmost side can be selected.

In this state, when it is desired to select the symbol of the second printing belt 42 from the right, the user operates the operating knob 37 and moves the set shaft 36 to the left. This operation
The operation is performed against the elasticity of the stop member 38, and the stop member 38 is pushed out from the fitted groove 36a at the position of FIG. 10 and falls into the groove 36a on the right side by the operation. At this time, the index 43a is located on the second print belt 42 from the right, and the pin 40 is fitted in the cut groove 41b of the second set wheel 42 from the right. Therefore, if the movement of the set shaft 36 in the left direction is stopped in this state, the second print belt 42 from the right is selected. The set shaft 36 is in a semi-fixed state in the left-right direction due to the fitting between the stopper member 38 and the groove 36a.

Next, in the second printing belt 42 from the right, a required symbol is selected. In that case, the setting shaft 36 may be rotated by the operation knob 37. When the set shaft 36 is rotated, the sleeve 35 rotates together with the fitting relationship between the pin 40 and the slit 35a, and the second set wheel 41 from the right also rotates with the fitting relationship between the pin 40 and the cutting groove 41b. I do. At this time,
The other five sets 41 do not move for the reasons already described. Also, the indicator 43 does not rotate because it is fitted in the hole 31a of the side plate 31, and only the relative angular position with respect to the set shaft 36 changes.

As is well known, the printing belt 42 is necessary because when a certain printing symbol is located at the cradle 33, the same heading symbol comes at the index 43a. The rotation of the set shaft 36 may be stopped when the heading symbol reaches the position of the index 43a. Then, the stop position is positioned in a semi-fixed state by a moderation mechanism including the ring-shaped portion 35c and the stop member 39. Therefore, the selected symbol always stops in an ideal state with respect to the receiving table 33, and the printing symbols of all the printing belts 42 are arranged in a line without shifting. In this way, a high quality printing surface can be reliably obtained.

Here, the description of the printing mechanism is finished, and finally, an essential configuration for attaching the label 12b to a package or the like will be described. This configuration is very simple, and the application roller 44 rotatably attached to the shaft 6 plays the role. Since the shape of the sticking roller 44 is well known, its detailed shape is not specified, but the cross-sectional shape is not constant, the contact surface with the label 12b is as small as possible, and the relatively large contact pressure is relatively uniform. It is devised so that it can be obtained. Further, in each of the drawings, the sticking roller 44 and the above-described locking member 15 seem to interfere with each other in operation, but actually, they do not interfere with each other and can operate independently. Are located in

Next, the setting operation of the label tape 12 and the printing / adhering operation will be sequentially described. First, in order to set the label tape 12 in a use state, the bottom cover 14 must be opened. The opening operation will be described with reference to FIG. FIG. 9A shows a closed state of the bottom cover 14.
In this state, the bottom cover 14 is bending the elastic portion 15d of the locking member 15 by the side wall 14b. In other words, the bottom cover 14 is pushed in the opening direction by the elastic portion 15d. However, the engaging portion 14h formed on the side wall 14b is connected to the hook portion 1 of the locking member 15.
This closed state is maintained because 5b is locked. At this time, similarly, the side wall 14c of the bottom lid 14 also makes the elastic portion 15e of the locking member 15 bend, and the engaging portion (not shown) is locked by the hook portion 15c of the locking member 15. I have.

In this state, when the finger contact portion 15a of the locking member 15 is pushed in, the locking member 15 rotates clockwise. Therefore, the elastic portions 15d and 15e with respect to the bottom lid 14 are provided.
Will become increasingly bigger. And then hook part 1
When the lock by 5b and 15c is released, the bottom cover 14 is pushed out vigorously and rotates counterclockwise on the shaft 5. FIG. 9B shows the moment when the locking is released, and FIG. 9C shows the state immediately after the bottom cover 14 starts rotating. Since the lock is released in this manner, regardless of the posture of the handler labeler, for example, with the bottom cover 14 up, not only the lock is released but also the bottom cover 14 is securely pushed out. It is. FIG. 8 shows the bottom cover 14 thus opened.

Next, a roll-shaped label tape 12 is set. In FIG.
3 shows a state in which it is attached. The operation for setting such a state has already been described, and thus will not be described here. In the state of FIG. 8, there are two methods for passing the leading end of the label tape 12 downward. In the case of the embodiment, the label 1 is placed above the mount 12a.
2b is temporarily affixed (front winding), so it may hang straight down as shown in the figure. However, when the label 12b is temporarily affixed to the lower side of the mount 12a (back winding), FIG.
In this case, the tape is hung downward along the guide portion 13a of the tape attaching member 13 and the guide portion 24c of the guide member 24.

After the state shown in FIG. 8, the bottom cover 14 is closed. At this time, when the bottom cover 14 is further rotated clockwise from the position shown in FIG. 9C, the side walls 14b and 14c of the bottom cover 14 are brought into contact with the elastic portions 15d and 15
e to push the locking member 15 in the counterclockwise direction, while the slopes 14f, 14g are hooked by the hooks 15b, 1g.
5c, the elastic portion 15d,
A force is applied to the locking member 15 in a direction in which the elastic force of the elastic member 15e is increased, that is, a clockwise direction. After sufficiently elastically deforming the elastic portions 15d and 15e in this manner, the two engaging portions 1
When 4h (the other engaging portion is not shown) gets over the hook portions 15b and 15c, the hook portion 15
b and 15c enter behind the engaging portion, and the closed state shown in FIG.

Next, the subsequent operation of the label tape 12 will be described with reference to FIG. FIG. 2 assumes that the label tape 12 is already in a usable state, but the tip of the label tape 12 still hangs down from the left end of the cradle 14e in this figure. In such a state, first, the hanging part of the label 12b is removed. And the mount 12a
Is inserted between the transfer drum 18 and the guide portion 14d, and at least one of the holes formed in the mount 12a is fitted to the pin 18a. And the manual lever 1
When the gripping operation of “0” is repeated, the transfer drum 18
Is rotated in the counterclockwise direction, and winds around the leading end of the backing sheet 12a. The rotation operation of the transfer drum 18 is performed in exactly the same manner as the operation during use, and will be described later in detail.

When the leading end of the mount 12a advances between the transfer drum 18 and the guide member 25 in this manner, the fitting with the pin 18a is released at the leading end 24d of the guide member 24, and the guide member 24 Guide part 24b and guide member 25
And the cutter portion 16b of the transmission member 16
And will come down again.
FIG. 2 shows a state in which the downward slack from the receiving table 14e is eliminated, and the hole formed in the label tape 12 is fitted to the hook 20a of the label stopper 20.
The state shown in FIG. In this state, if the user grips the end of the mount 12a by hand and twists it so as to move to the left, the mount 12a is cut by the cutter 16b.

Next, the printing / adhering operation of this embodiment will be described mainly with reference to FIG. 1 and FIGS. still,
4A to 7, each diagram (a) is a diagram viewed from the same direction as FIG. 1, and each diagram (b) is a diagram viewed from the back side of FIG. 1. FIG. 1 and FIGS. 4A and 4B show a stationary state. First, in the stationary state, the main body (outer walls 1 and 2) and the manual lever 10 are grasped, and both are grasped against the compression spring 11. Then, the manual lever 10 rotates clockwise in FIG. 4B. Then, the transmission member 16 starts rotating counterclockwise on the shaft 5 by meshing with the teeth 10h formed on the arm 10d of the manual lever 10. The clockwise rotation of the arm 10d causes the slide member 21 to slide to the left, and the locking portion 21b retreats from the stopper claw 20b.

The transmission member 16 is thus moved as shown in FIG.
Starting rotation in the counterclockwise direction in (b) means starting rotation in the clockwise direction in FIG. Therefore, in FIG. 4A, when the transmission member 16 starts rotating clockwise, the ratchet pawl 17
Moves to the right, and its claw portion 17b is
The long tooth surface of the tooth formed on the tooth 9 slides toward the tooth tip. Meanwhile, at the same time, arm 1
0c rotates counterclockwise, so that the pushing portion 10f
However, the tip of the elastic portion 17a of the ratchet pawl 17 is pushed down. Therefore, the elastic portion 17a is bent,
The elastic force acts as a resistance to the rotation of the arm 10c. Moreover, this resistance gradually increases.

On the other hand, in such a gripping stroke, the printer P descends with the rotation of the arms 10c and 10d. Then, first, the printing surface of each printing belt 42 comes into contact with the ink impregnated body 27b of the ink roller 27. Immediately thereafter, both ends of the receiving table 33 come into contact with the flange 27a of the ink roller 27 and push the ink roller 27.
Therefore, the ink arm 26 (see FIG. 1) supporting the ink roller 27 rotates counterclockwise against a spring (not shown). At this time, the ink roller 27 rolls on the above-mentioned printing surface to ensure the adhesion of the ink and retreats out of the locus of the printing surface. The state at this time is shown in FIG.
(A) and (b).

When the gripping stroke further proceeds from the state shown in FIG. 5, the claw portion 17b of the ratchet claw 17 gets over the tooth tip. At this time, the claw portion 17b is rapidly dropped on the long tooth surface of the next tooth due to the strong elastic force of the elastic portion 17a. Also,
This drop causes the arm 10c, that is, the manual lever 10
The printing device P instantaneously increases its descending speed, and the gripping operation on the manual lever 10 is instantaneously accelerated, and the label 12 placed on the receiving table 14e is increased.
b is impacted, and printing is performed. Therefore, even when the gripping operation is performed slowly, printing can be performed with a good print density. The state at this time is shown in FIG.
This is shown in (b).

After the printing is performed in this manner, when the grip force is released, the manual lever 10 enters a release stroke. Then, in FIG. 6B, since the arm 10d starts to rotate counterclockwise, the printer P starts to rise, and the transmission member 16
Starts rotating clockwise, and the slide member 21 starts moving rightward. In addition, the rotation of the transmission member 16 is determined according to FIG.
In FIG. 6A, since the rotation is in the counterclockwise direction, the ratchet pawl 17 starts moving leftward in FIG. At this time, since the arm 10c has also started to rotate clockwise, the tip of the elastic portion 17a slides on the pushing portion 10f without receiving much resistance. And the ratchet claw 17
7 (a) and 7 (b) show the state in which the claw portion 17b of the ratchet wheel 17b contacts the short tooth surface of the tooth of the ratchet wheel 19 which has passed over the tooth tip in the gripping stroke and is pushing the tooth surface.

Thus, in FIG. 7B,
The transfer drum 18 is rotating in the clockwise direction. Also, the label stopper 20 is also rotated clockwise by the backing paper 12a being pulled by the transfer drum 18,
The stopper 21b of the slide member 21 is
In the trajectory of. Further, the label tape 12 is fed, and the mount 12a is rapidly turned at the end of the receiving stand 14e. Therefore, the printed label 12b temporarily attached is peeled off from the mount 12a with its own rigidity, and the guide portions 14i, Adhering roller 4 on 14j
4 is proceeding downward.

The state in which the transfer drum 18 further rotates from this state and all operations are stopped is the stationary state shown in FIG. At this time, since the stopper claw 20b of the label stopper 20 is locked by the locking portion 21b of the slide member 21 and cannot be rotated, the transfer drum 18 cannot be rotated in the reverse direction. A predetermined degree of tension can be maintained between the and the transfer drum 18 without slack. Therefore, even when the label 12b is attached to an article or its package, there is no delusion of the mount 12a,
At the time of the next printing, it is possible to print at the correct position of the label 12b and to prevent the character from rubbing.

Incidentally, FIGS. 4A and 4B originally show
Since it is shown as a state before use, after printing, the label 12 which is further fed below the adhering roller 44 is printed thereon.
b is not shown. At this time, the printed label 12b further fed from the state shown in FIG. 7 is almost peeled off from the backing sheet 12a, but the rear end is still in contact with the backing sheet 12a, and the peeled portions are the guide portions 14i and 14j. Riding on This state is shown in FIG. Therefore, when attaching the printed label 12b to a package or the like, in FIG. 2, the label 12b may be moved downward, pressed against the package or the like, and pulled to the right. At this time, the sticking roller 44 rolls on the printing surface of the label 12b, and sticks reliably.

Although the printer P of this embodiment has been described as a printer mounted on a handler labeler, the printer of the present invention can be implemented as a single printer. Further, in the above embodiment, the sleeve 35 is provided with the annular portion 35c having a plurality of concave portions,
Although 9 is attached to the side plate 30, on the contrary, a stopper member may be provided on the sleeve 35 and an annular inner peripheral surface having a plurality of recesses may be provided on the side plate 30. Furthermore,
The pin 40 as the connecting means protrudes from the set shaft 36 to only one side, and only one slit 35a formed in the sleeve 35 may be provided. In that case, if one end of the slit 35a is formed up to one end of the sleeve 35,
Assembling of the sleeve 35 and the set shaft 36 becomes easy. Further, in the embodiment, the pin 40 as the connecting means is press-fitted into the set shaft 36, but the connecting means can move together in the axial direction and the rotation direction of the set shaft 36 regardless of the press-fitting. A known configuration is also known, and the present invention can be applied to such a configuration.

As described above, according to the present invention, since the moderation mechanism is not related to all the set cars, but is related only to the sleeve, it is not influenced at all by the number of the set cars. In addition, it is possible to obtain a printing device which has a very simple structure and is suitable for cost reduction.
