For recording media such as Disk Recordable / Rewritable), in order to enable discrimination from other recording media of the same shape,
A label that prints and displays an arbitrary image or character is attached. The label to be attached to the recording medium is generally adhered to the mount, and the label is peeled off from the mount, the label is aligned with the recording medium, and then the recording medium with the label is attached by attaching the label to the recording medium. It is said.

In order to attach a label to a recording medium, for example, Japanese Patent Application Laid-Open Nos.
Japanese Unexamined Patent Publication (Kokai) No. 263328 discloses a technique relating to a dedicated jig for an operator to attach a label.

[0004]

However, since the dedicated jig disclosed in the above publication requires the operator to manually apply the label, it takes time and effort to apply the label, and the sticking failure due to a work error, and Problems such as poor appearance due to the inclusion of bubbles at the time of sticking may be considered.

[0005] In view of the above proposal, the present invention automatically attaches a label to a recording medium without manual operation, and
An object of the present invention is to provide a label sticking apparatus and a sticking method capable of improving appearance and sticking accuracy.

[0006]

(Operation) Next, the operation of the CD label sticking apparatus 1 of the present embodiment will be described. The operation of each unit of the mechanical unit is such that the CPU 301 of the control unit 300 fetches the detection information from the sensor control
According to the program and various setting information stored in
A processing command is issued to each unit via the motor brake control unit 309, and each unit operates in accordance with the processing command. However, description of the command from the CPU 301 is omitted, and after the command from the CPU 301 is received. The operation of each unit will be described.

Each unit of the mechanical section performs an initial operation prior to the start of the processing operation when the power is turned on, when the label supply roll 40 or the mount roll take-up roll 41 is replaced, and when the jam processing is completed. In this initial operation, each unit is positioned at the home position, which is the initial position, and waits until an operation start command is issued.

When a processing start signal is issued from the touch panel 3 or an external computer, the label supply unit 10
Is to drive the stepping motor M1 by a predetermined pulse to convey the label sheet LS in the forward direction (after completion of the positioning), and to form a peeling guide that becomes an acute branch point between the horizontal conveying path P1 and the inclined conveying path P2. The label tip is peeled off at the tip of the plate 36 and stopped at a predetermined position.

Next, the detection of the label L by the label presence / absence detection sensor S3 is performed, and if it is determined from the detection signal that the label L is present (the CPU 301 makes an affirmative determination that the label L is present, and drives the stepping motor M2). When a forward rotation driving command signal is sent to the driver), the gripper unit 60 of the label transport unit 50 moves horizontally to the label supply unit 10 side, and rotates the upper jaw 70 at a predetermined position to be fixed to the lower jaw 71 fixed. Hold the label L.

Next, the gripper unit 60 moves horizontally to the side of the bush attaching / detaching unit 90 and pulls out the label L from the label sheet LS. At this time, the label supply unit 10 synchronizes with the pull-out conveyance of the label L of the gripper unit 60. Then, the label sheet LS is transported by a predetermined distance at which the label L is completely peeled off and stopped. In this stopped state, the leading end side of the subsequent label L jumps out from the acute angle branch point by about several millimeters and peels off (see FIG. 5).

Next, the label sheet LS, from which the preceding label L has been peeled off, is switched in the transport direction and transported in the reverse return direction (the direction opposite to the arrow A in FIG. 4) to locate the subsequent label L. When the detection hole Ba is detected by the label home position detection sensor S1 (ON by reflection), the return direction is a predetermined distance from the tip of the detection hole Ba (start point of detection ON) to the center of the detection hole Ba. (FIG. 4
(In the direction opposite to the arrow A in FIG. 3), stops and waits until the label sheet LS is conveyed for peeling off the next label L.

On the other hand, when the detection of the label L by the label presence / absence detection sensor S3 is negatively determined by the CPU 301 (when it is determined that there is no label L), the operation of the label supply unit 10 is stopped as a jam occurs, and the touch panel is stopped. 3 indicates that a jam has occurred.

When the above processing start signal is issued,
The suction pad support plate 160 of the CD transport unit 140
CD stacked on top of the CD supply unit 190
After the position of the upper surface of the CD is detected by detecting the position of the upper surface of the CD, the CD is sucked and moved upward, and moves in a horizontal direction at a predetermined position (see FIG. 2).
Stop at a position adjacent to 10 and wait.

The gripper unit 60 that pulls out and conveys the label L stops after conveying the pulse-controlled predetermined distance. Even in this stop position, the holding of the label L is still continued.

Next, the sticking stage 120 of the sticking stage unit 110 rises, and the positioning boss 121 arranged substantially at the center of the sticking stage 120 penetrates the center hole of the conveyed label L. When the positioning boss 121 stops at a predetermined position where the positioning boss 121 can engage with the bush 91 after penetrating the label L (see FIG. 17A), the rotation of the cam 98 pushes up the lever 100, and the bush 91 is separated and positioned. It is positioned above the boss 121 and integrated (see FIG. 17B). At this point, the sensor S7 detects that the bush 91 has been detached. continue,
The cam 98 is returned to the home position (see FIG. 17C). In FIG. 17C, the positions of the bush 91 and the positioning boss 121 are the same as the positions shown in FIG. 17B. Next, the attaching stage 120 starts moving down with the detached bush 91 (see FIG. 17D), and further descends to a predetermined position for positioning and attaching to the CD and stops.

When the detachment of the bush 91 is confirmed by the bush state detection sensor S7, the upper jaw 70 of the gripper unit 60 is turned to the open state, and the gripper unit 60 is opened.
Moves horizontally by a predetermined amount in the direction further away from the label supply unit 10 and stops. During this time, the label L is slightly dropped by the center hole penetrating the positioning boss 121 having the tapered surface, the positional deviation is corrected by the tapered surface, and the label L is positioned at the predetermined mounting position on the attaching stage 120.
Is completed.

Subsequently, when the sticking stage 120 stops at the above-described predetermined position, the positioning protrusion 136 protruding from the gear 135 of the stage rotating unit 130 moves to the cylindrical member 1.
24, the stepping motor M6 of the stage rotation unit 130 is rotated by a predetermined angle (180 degrees) in one direction, and is projected from the gear 135 into a fitting groove formed at the lower end of the cylindrical member 124. Fitting projection 137 is fitted,
The attaching stage 120 and the stage rotating unit 130 are integrated. Subsequently, C by the CD transport unit 140
The positioning of D is performed. C waiting at a predetermined position
Upon receiving the completion of the movement of the attaching stage 120 to the predetermined position, the suction pad supporting plate 160 in the D-adsorbing state moves in the horizontal direction toward the attaching stage 120 and moves to the attaching stage 120.
(See FIG. 18). Subsequently, after a slight lowering operation is performed to stop at a predetermined position, the suction of the CD is released and the CD is dropped by a small amount. The falling CD
A slight positional deviation is corrected in the center hole by the tapered surface of the upper end projection 91a of the bush 91, and the center hole is placed on the flange surface 91b (see FIG. 19A). At this time, sticking stage 1
The labels L and CD placed on the top 20 are concentrically positioned vertically at a predetermined distance (space).

Next, the two suction pads 162 fixed to the suction pad support plate 160 descend and press the CD side, whereby the CD and the label L placed on the sticking stage 120 are pressed against each other, and the label is pressed. L and CD are attached (first attaching operation). That is, the positioning boss 121
Is urged by the spring 125 so as to be able to move up and down, so that it is sunk downward against the urging force of the spring 125 due to the pressing by the suction pad 162, and the elastic force of the sponge 122. Both are attached together with (see FIG. 19B). At this time, by pressing two points on the center line of the CD corresponding to the uppermost position of the kamaboko-shaped sticking stage 120 and sandwiching the center hole of the CD, as described above, the elasticity of the sponge 122 is increased. Accordingly, both are sequentially bonded to each other in two opposite directions from the center line.

When the first sticking operation is completed, the suction pad supporting plate 160 is raised, and the stage rotating unit 130 is driven to rotate the sticking stage 120 by a predetermined angle. At this time, the suction pad 162 has released the suction of the CD, but the urging force of the spring 125 described above
The CD placed on the flange surface 91b of the bush 91 also rises by an amount corresponding to the urging force of the spring 125.
Next, the suction pad support plate 160 is lowered again to suck the CD with the suction pad 162, and then the suction pad support plate 160 is raised to move the suction pad support plate 160 from the kamaboko-shaped attaching stage 120 to C.
D is lifted. Then, the stage rotation unit 1
30 is driven, the pasting stage 120 is rotated by a predetermined angle in the direction opposite to the previous direction to return to the original position, and then the above-described pasting operation is performed again. Although the pressing operation of the CD, that is, the relative position between the stick-shaped sticking stage 120 and the label L (CD) changes by the sticking operation, the surface of the CD always corresponding to the highest position of the stick-shaped sticking stage 120 is changed. Will be pressed. In the present embodiment, the sticking operation is repeatedly performed a plurality of times. However, the rotation direction, the rotation angle, and the number of rotations of the sticking stage 120, and the number of times the CD is pressed by the suction pad 162 are not limited thereto. Absent.

When the sticking (pressing) operation by the suction pad 162 is completed a plurality of times, the suction pad 162 sucks the last pressed portion of the CD and conveys the labeled CD to the CD discharge unit 170. After slightly raising the suction pad support plate 160, the process moves to the horizontal direction (the direction opposite to before the label L is applied), and the labeled CD is conveyed to the CD discharge unit 170.

The sticking stage 120 where the label L is no longer placed rises at a predetermined timing, and the upper end projection 91a of the bush 91 on the tip side is moved to the bush attaching / detaching unit 90.
The bush 91 stops at a position where the flange surface 91b of the bush 91 contacts the bottom surface of the bush receiver 103 while pushing up the tip of the lever 100 by engaging with the bush receiver 103, so that the bush 91 can be detached from the positioning boss 121. Attachment stage 1 attached to bush attaching / detaching unit 90
20 descends and stops at a predetermined position.

The bush 9 to the bush attaching / detaching unit 90
When the mounting of No. 1 is detected by the bush state detection sensor S7,
The gripper unit 60 starts moving in the horizontal direction (return direction toward the label supply unit 10) and stops at the home position.

When the CD labeled by the suction pad support plate 160 is conveyed in the horizontal direction to the CD discharge unit 170, and the leading end of the CD is conveyed to a position where the roller pair 176, 177 can be nipped, the suction pad is pressed. Support plate 160
Is stopped, the roller 177 and the small-diameter roller 175 move toward the lower roller 176 and the large-diameter roller 173, and the nip operation is performed by the pair of rollers 176 and 177. 173, 175
Transported to

When the pair of rollers 176 and 177 surely nip the labeled CD, the suction pad 162
Is released, and is stopped after moving to a predetermined position (horizontal movement after ascending). The CD conveyed and nipped by the roller pairs 173 and 175 is further fed by the rotation of the roller pair. At this time, the label is completely attached to the CD by the pressing action of the roller 173 on the entire label surface. This is done. The labeled CD conveyed by the roller pairs 173 and 175 is horizontally supported by the three claws 181 and 187, and the center projection of the CD accommodating holder 201 disposed below by the retreating operation of the claws 181 and 187. The sheet is penetrated by 202, and is stacked and accommodated in the CD accommodation holder 201. In conjunction with the retreating operation of the claws 181 and 187, the rollers 175 and 177 move upward (in a direction away from the rollers 173 and 176) and stop at a predetermined position.

With the above, the sticking process of the first sheet is completed, and the number set by the touch panel 3 or the external computer is continuously performed in the same manner.

(Operation and the Like) Next, the operation and the like of the CD label attaching apparatus 1 of the present embodiment will be described, focusing on temporary attachment and main attachment.

In this embodiment, the label transport unit 10
From the CD transport unit 190 and the label and C respectively.
After receiving the transport of D and temporarily attaching the CD, the CD labeled with the CD transport unit 140 is removed from the CD discharge unit 17.
0 and transport the label L to the CD
Since the sheet is ejected after being attached to the entire surface of D, the CD and the label L can be automatically attached without the manual operation of the operator. For this reason, it is possible to eliminate human error that occurs in the attaching operation.

In this embodiment, the bush 91 comes into contact with the positioning boss 121, and the labels L and CD penetrate through the positioning boss 121 and the bush 91, respectively, and are positioned coaxially at a predetermined interval. When the temporary attachment is performed by pressing with the suction pad 162, the accuracy of attaching the label L to the CD can be improved. Further, since the shape of the sponge 122 in contact with the label L is a semicylindrical shape, the label L is in a curved state when the label L is placed on the sponge 122, and the label L is pressed when the CD side is pressed by the suction pad 162. It is possible to discharge air between the CD and the CD. For this reason, at the time of temporary sticking, it is possible to prevent air bubbles from being mixed between the label L and the CD.

Further, in this embodiment, at the time of temporary attachment, a plurality of spaced portions are pressed by the suction pad 162 so that the label L is
Since the label L is attached to D, the label L is not peeled off the CD or displaced when it is sucked by the suction pad 162 and transported to the CD discharge unit 170. Further, by driving the stage rotating unit 130 and pressing a plurality of portions of the CD (same for the label L) whose relative position with respect to the semicircular pasting stage 120 has changed, the CD
Since the operation of attaching the label L to the outside is performed each time from the inside, which is the center line of the two, to the outside,
It is possible to reliably prevent bubbles from remaining between them.

Further, in the present embodiment, the labels L and CD are brought into pressure contact with one another (in the direction of arrow C in FIG. 14) by the wide pair of rollers 173 and 175. The air between the and the CD is exhausted in one direction,
It is possible to prevent air bubbles from being mixed between both at the time of the entire surface application (main application). In addition, since the roller 175 in contact with the soft label L is a low-hardness roller, the label L is not damaged when the entire surface is stuck. Further, the small-diameter roller 1 is synchronized with the movement of the suction pad support plate 160.
Since the roller 75 and the roller 177 can be rotated to be able to be separated from and contacted with the large-diameter roller 173 and the roller 176, the CD on which the label L has been temporarily attached is reliably received in the state of the temporary attachment, and the operation shifts to the entire attachment (final attachment). can do. In other words, it is possible to prevent defects such as deviation of the label L and wrinkles that occur when the CD temporarily attached to the pair of rollers in the contact state enters, and furthermore, it is possible to avoid a defective conveyance of the CD due to these defects. .

In this embodiment, the attaching stage 12
Although an example is shown in which the mounting surface of No. 0 has a Kamaboko shape, the present invention is not limited to the Kamaboko shape as long as air bubbles between the labels L and CD can be prevented.

In this embodiment, the labels L and CD
Is shown as a fixed position with respect to the attaching stage 120, and the attaching stage 120 is rotated. However, after a single attaching operation, the labeled CD is sucked up by the attracting pad 162 and only the attaching stage 120 is rotated. Thus, the positions of the label L or CD and the attaching stage 120 may be changed. Further, in the present embodiment, the pressing operation of the suction pad 162 on the CD is temporarily attached,
Although the description has been made as the actual sticking with the contact action on the entire surface of the label L by the roller 173 of the D discharge unit 170, the first pressing operation by the suction pad 162 is the temporary sticking, and the sticking stage 120 is rotated to make a CD (label). The pressing operation by the suction pad 162 after the second time performed by changing the relative position of the above may be the actual sticking. This is because the label L is stuck on the entire surface of the CD by rotating the sticking stage 120 to make the relative position to the CD (label) different and performing a further pressing operation. The purpose can be achieved. Furthermore, in the present embodiment, an example is shown in which the CD is pressed by the suction pad 162 and the CD is attached to the label L. However, a pressing member that is different from the suction pad 162 and is adapted to the mounting surface of the attachment stage 120 is separately prepared. The CD may be pressed by the pressing member.

In this embodiment, a disk-shaped CD is used as a recording medium, and a disk-shaped label L to be affixed to the CD is used.
However, the present invention is not limited to this, and can be applied to a label sticking apparatus and a method for sticking labels on recording media of various shapes in the claims described above. .

(Second Embodiment) Next, a second embodiment in which the label sticking apparatus and the label sticking method according to the present invention are applied to the above-described CD label sticking apparatus will be described.
In this embodiment, a label L is attached to a CD placed on an attaching stage. In this embodiment, the same members as those of the first embodiment are denoted by the same reference numerals, and the description thereof will be omitted. Only different points will be described.

As shown in FIG. 20, in the CD label sticking apparatus 400 of this embodiment, the label supply roll 40 is disposed above the mount roll 41 and the label sheet L
S is folded back from the horizontal transport path P1 by the peeling guide plate 36 and wound up on the mount winding roll 41 via an inclined transport path P2 inclined downward. The label L whose tip has been peeled off by the peeling guide plate 36 is pulled out by the gripper 458 and transported. Since the lower side of the label L is conveyed with the adhesive surface, the lower jaw of the gripper 458 has a saw-like shape that is in line contact with the adhesive surface of the label L.

The CD label attaching apparatus 400 chucks the center hole of the CD from the CD supply unit 190 and
Is provided with a CD chucking transport unit (not shown) for transporting. Although the CD chucking transport unit has the horizontal movement mechanism and the vertical movement mechanism shown in the first embodiment (see FIG. 13), since the CD is transported by chucking instead of suction transport, the CD is transported. The label sticking apparatus 400 lacks the vacuum pump unit 5 and the solenoid valve 166 of the first embodiment.

The CD label pasting apparatus 400 includes a pasting stage 401 having a substantially horizontal mounting surface.
On the attaching stage 401, as described later, after the center line direction of the label L is pressed against the CD to perform the temporary attaching, the actual attaching is performed in which the label L is entirely attached to the CD. For this reason, the CD label sticking apparatus 400 does not include the CD discharge unit 170 shown in the first embodiment. Further, the attaching stage 401 is configured to be movable in a horizontal and vertical direction between a temporary attaching section for performing temporary attaching and a permanent attaching section for performing actual attaching. As will be described later, the sticking section is provided with a fixed sticking roller 410 that is placed on the sticking stage 401 and that can rotate and contact the entire surface of the label L (see FIG. 23A). .

The sticking stage 401 is a CD that can be inserted into the center hole of a CD and has an outer diameter slightly smaller than the center hole of the CD.
It has an insertion projection 402. The CD insertion protrusion 402
The solenoid is fixed to a plunger of a solenoid (not shown) built in the attaching stage 401, and the solenoid O
By N and OFF, it protrudes or retreats from the mounting surface of the attaching stage 401. In addition, the CD label sticking apparatus 400 includes:
It has a cylindrical positioning bush 403 having a tapered surface whose inner diameter can be brought into contact with the outer diameter of the CD insertion projection 402 and whose diameter is reduced upward. The positioning bush 403 is attached to the CD insertion protrusion 402 from above by a positioning bush attachment unit (not shown).

Further, the CD label sticking apparatus 400 has four lower rollers 404 which can be advanced from the outside of the sticking stage 401 to the outer peripheral portion of the sticking stage 401 and come into contact with the CD placed on the sticking stage 401. are doing. These lower rollers 404 have a structure that can be retracted from the sticking stage 401 when a CD is placed on the sticking stage 401 (see also FIG. 23C). In the upper part of the lower roller 404, four upper rollers 405 having a diameter larger than that of the lower roller 404 and movable in the vertical direction are arranged corresponding to the position of the lower roller 404. Further, a temporary sticking pressing member 406 which has a substantially semi-cylindrical shape and which can insert the positioning bush 403 at the center thereof is disposed above the upper roller 405 and between the upper rollers 405 so as to be vertically movable. .

As shown in FIGS. 20 and 21, the gripper 458 horizontally moves between the positioning bush 403 contacting the CD insertion protrusion 402 and the temporary attaching pressing member 406, and between the upper roller 405. It can move in any direction.

Next, the operation of the CD label sticking apparatus 400 will be described. In this embodiment, the operation of each unit is controlled by the control unit as in the first embodiment.
Description of detection by the sensor and control by the CPU will be omitted.

When a processing start signal is issued from the touch panel 3 or an external computer, the solenoid plunger built in the sticking stage 401 is attached to the sticking stage 40.
1 on the mounting surface. Next, the CD chucking / conveying unit chucks and conveys the CD placed on the uppermost portion of the CD supply holder 191.
The chucking is released by descending to a position where it can enter the tapered surface of the insertion projection 402. At this time, the lower roller 404
Are retracted to the outside of the attaching stage 401 as shown in FIG. The CD falls and the CD insertion protrusion 40
2 is passed through the center hole and mounted on the attaching stage 401. Next, the position bush boss 403 descends and comes into contact with the CD insertion protrusion 402, and the lower roller 40 in the retracted state is moved.
Numeral 4 advances onto the attaching stage 401 and contacts the CD.

Next, the gripper 458 is connected to the label sheet LS.
The label L pulled out of the label L is conveyed to the upper side of the sticking stage 401 with the adhesive surface facing down, and stopped at a position where the center hole of the label L can be inserted into the positioning bush 403 to release the nip (FIG. 22 ( A)). Along with the lowering of the upper roller 405, the label L falls, and a slight positional deviation is corrected on the tapered surface of the positioning bush 403, and the label L penetrates through the positioning bush 403. It is supported by 404 (see FIG. 22B).

Subsequently, the temporary sticking pressing member 4 located above
By lowering 06 and pressing in the diametric direction which is the center line of the label L, a part of the label L (near the center line) is attached to the CD, and temporary attachment is performed (see FIG. 22C). At this time, since both sides of the label L are supported by the lower roller 404 and the upper roller 405, the label L is not stuck on the CD and maintains a forced curl posture (curved state).

Next, the temporary sticking pressing member 406 and the upper roller 405 are retracted upward (see FIG. 22D).
After the positioning bush 403 is retracted upward and the CD insertion protrusion 402 is also retracted into the attaching stage 401, the attaching stage 401 is moved in the horizontal and vertical directions, and the fixed attaching roller 410 of the actual attaching portion is attached to the label L. The movement of the attaching stage 401 is stopped at a position where the attaching stage 401 comes into contact with the center line (see FIG. 23A). Thereby, the attaching stage 40
1 means that the movement from the temporary attaching section to the actual attaching section is completed. At this time, since the label L is attached near the center line and both sides are supported by the lower roller 404, the label L is transferred to the actual attaching portion while maintaining the curl posture.

Then, the attaching stage 401 is moved in the horizontal direction (the direction of the arrow F in FIGS. 23B and 23C or the direction opposite thereto).
By reciprocating the label L, the entire surface of the label L is attached to the CD by the pressing action of the attaching roller 410 against the label L.
In other words, in the present attaching section, the label L holding the curl posture by the temporary attachment is attached to the CD by sequentially changing the posture in the horizontal direction as the attaching stage 401 moves in the horizontal direction and the attaching roller 410 rotates. Then, the sticking stage is completely stuck to the CD by reciprocating in the horizontal direction of the sticking stage. It should be noted that the lower rollers 404 positioned on both sides of the label L retreat outside the attaching stage 401 with the relative movement between the attaching roller 410 and the attaching stage 401 (FIG. 23).
(C)).

When the sticking at this sticking section is completed, the sticking stage 401 is returned to the temporary sticking section, and the lower roller 40
4 is retracted to the outside of the attaching stage 401, and then chucked by the CD chucking transport unit to transport the labeled CD to the CD storage holder 201, thereby completing the first attaching process.

Next, the CD label sticking device 4 of the present embodiment
The operation and the like of 00 will be described mainly on temporary attachment and main attachment. In the present embodiment, a description of the same operational effects as those of the CD label sticking apparatus 1 can be omitted.

In the present embodiment, the label L is forcibly curled at the time of temporary sticking, and only the vicinity of the center line of the label L is pressed onto the CD by the temporary sticking pressing member 406, and the label L is forcibly attached at the time of actual sticking. Straighten curls and label L and C
Since the entire surface is stuck to the CD while the air between D is exhausted, it is possible to prevent air bubbles from entering between the label L and the CD as in the first embodiment. Therefore, it is possible to obtain a labeled CD having no air bubbles, thereby eliminating appearance defects.

In the present embodiment, an example is shown in which the sticking roller 410 of the sticking section is rotatable and the label L is pressed by the rotation of the sticking roller 410. A member that can be in sliding contact with the label L may be used.

In this embodiment, the example in which the attaching stage 401 is reciprocated with respect to the fixed attaching roller 410 is described. However, the attaching stage is fixed and the attaching roller is reciprocated in the horizontal direction. Alternatively, both may be relatively moved at the same time.

Further, in this embodiment, the attaching stage 40
Although the example of performing the temporary attachment and the actual attachment on 1 has been described, the stages for performing the temporary attachment and the actual attachment are separately provided, and the CD, the curled label, and the positioning bush are collectively provided from the stage where the temporary attachment is performed. You may make it move to the stage which performs this sticking. In this case, for example, a flange surface for supporting the CD is formed at the lower end of the positioning bush, and the CD bushing 402 is brought into contact with the CD insertion projection 402 from below the center of the attaching stage. The temporary sticking may be performed while being supported, and the positioning bush may be moved upward after the temporary sticking, whereby the CD and the curled label may be collectively moved to the stage where the actual sticking is performed.
