JP5406367B2 - Manual strip applicator especially for correction - Google Patents

Description

  The present invention relates to an apparatus comprising a strip or ribbon capable of transporting a member onto a substrate. More particularly, the present invention relates to a manual strip applicator, which supports a grippable casing, a movable attachment head that moves relative to the casing and protrudes from the casing in a use configuration, and a member mounted on a substrate. And a strip moving device disposed in the casing and designed to move the strip over the deposition head. Such devices are generally usable with one hand and can be stored in a pencil case.

  This type of applicator is well known for applying correction films, pastes or other materials that are bonded to substrates. Some models have retractable heads that protect the heads when not in use.

  As an example, Patent Document 1 describes an applicator including a button for projecting an attachment head. A spring disposed inside the main body loads the element with an elastic force toward the retracted position. When the head advances, the spring is compressed. When the head reaches the protruding position for use, the head is locked at a predetermined position by the lock mechanism. Retraction of the attachment head can be performed quickly by a lock release mechanism.

  The advantage of the strip applicator is that the final situation of the applied member is often not as desired. This is especially true in the case of transfer of correction films. If the user relieves pressure on the support, the film will not adhere correctly to the support. There is also a problem with the end of painting. The film may be too short or too long to cut accurately.

  Thus, this type of applicator device presents certain handling difficulties for users who desire more accuracy in film transport in order to obtain clean documents.

  Other types of applicators are known, which are specifically designed to limit the length of the supplied strip by limiting the rotation of the strip movement device, and are attached during a single transfer operation. The support strip that moves over the head is predetermined. U.S. Pat. No. 6,057,089 discloses this type of applicator, and transfer can only be performed in isolated rules by stamping similar to stamping. This strip length limitation reduces the benefits of this applicator. Furthermore, this type of applicator is not capable of accurate transfer. This is because the generally rectangular deposition head covers a large surface and therefore has reduced visibility in the target area.

  An object of the present invention is to provide a manual strip applicator with improved accuracy of application of members onto a substrate.

For this purpose, the present invention
A grippable casing;
A movable attachment head that moves relative to the casing and protrudes from the casing in a use configuration;
A support strip for supporting a member mounted on the substrate;
A strip moving device disposed in the casing and designed to move the strip over the deposition head;
A manual strip applicator comprising:
The applicator additionally comprises a return device connected to the casing and the attachment head,
The return device allows displacement between a proximal position and a distal position associated with the casing of the attachment head in the use configuration and loads a restoring force that moves the mounting head to the distal position in the use configuration. A formed manual strip applicator is proposed.

  The realization of such a return device appears to generally improve the quality of the application of the component on the substrate, in particular the application of the correction film on a sheet of paper. Thus, smoothness and even coating of the substrate is easily obtained. There is a significant reduction in application defects at the end of the film material, near the position where the strip applicator is lifted, and there is also a reduction in defects at the same position where the material is cut.

  The inventor describes this improved result and improved ease of use when the device is lifted from the substrate by more rapid lifting of the deposition head from the substrate. When the user begins to wake up the strip applicator, the attachment head remains in contact until it reaches a distal position as far as possible from the casing from the attachment head. Just at that moment, the user's hand is moving faster than at the beginning of the movement, and as a result, the hand leaves the substrate more quickly. This facilitates the cutting of the film material or, in relation to the material supplied to the patch on the support strip, facilitates complete separation even if only partially supported by the attachment head .

  According to a special feature of the present invention, the strip moving device is simply moved by the pressure applied at the deposition head during the mounting of the member. Thus, the member (coating film or similar member) is transferred from the support strip to the receiving surface only when the deposition head moves over the transfer surface. The strip is actually unwound and pressed against the receiving surface by the deposition head under the effect of displacement of the deposition head parallel to the receiving surface. The attachment head has a thin end so that the support strip bends around the end.

  Preferably, the amplitude of the displacement of the attachment head between the distal position and the proximal position is between 2 and 10 mm, preferably between 6 and 8 mm. According to the first tests carried out, these numbers provide a good compromise between the quality of application of the components, in particular the end of the correction film, and the ease of use. Low numbers can reduce the quality of film cutting for some users, while high numbers can create an unpleasant sensation for users accustomed to applicator devices with a fixed head in the mode of use.

  Preferably, the restoring force toward the proximal position of the attachment head between the distal position and the proximal position is between 0.5 and 12N, preferably between 1 and 8N, when approaching the proximal position Increase very significantly.

  The expression “very prominent” suggests that the increase in force is greater than that in direct proportion, such as the force obtained from a metal coil spring between the distal and proximal positions. These force numbers give the user a need for a certain reaction of the head in use to improve sudden movements when lifting the attachment head and give the user an uncomfortable feeling of the head retracted inward. It suggests an advantageous compromise between the numbers that would be too low.

  According to another special feature, the return device comprises at least a first magnet member and a second magnet member, wherein the first and second magnet members are generally facing each other in the use configuration and in the opposite direction in this configuration. It arrange | positions so that a magnetic field line may be generated. This arrangement optimizes the magnetic repulsion. Unlike the spring repulsion, the magnetic repulsion does not change linearly with the displacement of the deposition head (the magnetoresistance increases when the two ends of the magnetic system are pulled close together). In particular, this prevents the head from retracting excessively during use.

  According to another particular feature, the second magnet member is integrally attached to the strip moving device and is designed to generate magnetic field lines that are substantially parallel to the direction of displacement of the deposition head in the form of use. This arrangement facilitates the displacement of the attachment head.

  According to another special feature, the casing comprises a member for guiding the translational movement of the strip movement device, such that the member is substantially in contact with the first magnet member at a position proximal to the attachment head. Designed. When approaching the proximal position, the repulsive force becomes very large (much greater than the spring force), resulting in a magnetoresistance that pulls the head further.

  In another particular feature, the first magnet member is connected to a manually actuated member designed to control rotation of the first magnet member between a first position and a second position, The applicator is in the usage form of the attachment head, and the second position is the retracted position of the attachment head. Thus, the arrangement of the actuating member, for example in the form of a knob, can be simplified compared to a system using a push button and an additional unlocking element. The deposition head and strip are advantageously protected in the retracted position, limiting the risk of sudden actuation of the applicator.

  According to another special feature, each of the first magnet member and the second magnet member has a substantially flat side surface facing each other in the use mode and the retracted mode. Therefore, the attracting force and the repulsive force become stronger by the friend when approaching between the magnets. However, these flat surfaces do not hinder the rotation of the first magnet member.

  According to another special feature, the first magnet member comprises a monopolar surface at the two opposite ends, and the rotation of the magnet member takes place around an axis perpendicular to the direction of displacement of the deposition head. This arrangement minimizes the force that must be applied to displace the first magnet member when one face of the magnet is magnetically attached to a magnet that is an integral part of the movable strip moving device. Yes.

  According to another special feature, the second magnet member comprises a substantially flat surface facing at least bipolar and facing the first magnet member, the first magnet member having an axis of rotation parallel to the direction of displacement of the attachment head. I have. Due to the difference in polarity between the two regions (eg, two adjacent regions) in the face of the rotation and the magnet, this arrangement advantageously reduces the force applied to change the position of the deposition head. This arrangement is also compact because it is not necessary to move the magnets away from each other.

  According to another special feature, the attachment head and the strip movement device are integrally attached and guided in translation by a guide member of the casing, the return device being a first magnet member fixed to the casing; A second magnet member fixed to the strip moving device. Thus, the return device can be arranged within the extension of the strip moving device, which can form the strip reel and make the front volume of the applicator particularly small. is there. This simplifies operations for the user that can occur on the opposite side of the application head.

  According to another special feature, in the form of use, it comprises a member for adjusting the position of the first magnet member along the direction of displacement of the deposition head. Thus, the repulsive force can be adjusted by the user to counter the pressure that the user desires to retract the head.

  Another object of the present invention is a simpler design applicator with a movable attachment head that is easily actuated by a user.

For this purpose, the present invention
A grippable casing;
A movable attachment head that moves relative to the casing and protrudes from the casing in a use configuration;
A support strip for supporting a member mounted on the substrate;
A strip moving device disposed in the casing and designed to move the strip over the deposition head;
A manual strip applicator comprising:
The applicator includes a magnetic device having a first magnet member connected to the casing and a second magnet member connected to the attachment head, and the magnet device is used from a position in the casing corresponding to the retracted form. An applicator that moves to a protruding position corresponding to the form is proposed.

  Therefore, the mobility of the transfer head can be obtained without the user operating the spring compression mechanism. It is sufficient to change the position of the magnets or similar parts, and can generally be performed without attempting to use small sized magnet parts. Both directions of displacement of the deposition head are preferably dependent on the operation of the same actuating member.

  According to a special feature of this embodiment, the magnet device comprises a manual actuating member with two adjustment settings, the first magnet member being connected to the manual actuating member, and the second magnet member being a strip moving device. It is attached integrally. Thus, for example, the retracted position is advantageously maintained by the effect of magnetic attraction, allowing the transfer head to be maintained inside the casing and protecting it from impacts.

  Other features and advantages of the present invention will become apparent from the following description of several embodiments, provided as non-limiting examples with reference to the accompanying drawings.

It is sectional drawing which showed the inside of the applicator in the usage form by suitable 1st Embodiment of this invention. It is the figure which showed the applicator of FIG. 1 in a retracted form. It is the figure which showed the external appearance of the applicator by embodiment of FIG. 1 and 2. FIG.

FIG. 8 shows the position of attraction between two magnet members of a return device integrated in an applicator as shown in FIG. FIG. 8 shows the position of repulsion between two magnet members of a return device integrated in an applicator as shown in FIG.

  In the different figures, the same reference signs refer to the same or analogous elements.

  The applicator 1 allows the member to be accurately placed on a sheet or other substrate. If it is straightening, the adhesion of the member is instantaneous and there is no drying time. The member used is selected on the basis of its adhesive properties to a substrate, such as sheet paper, for example, and is not described in detail here as the invention is not particularly relevant to this member. The applicator 1 can of course be used in other applications, for example for coloring or covering the substrate.

  With reference to FIGS. 1, 2, 5 and 6, the applicator 1 comprises a body which forms a casing 2 consisting of complementary shells 2a, 2b, for example, fixed to each other. The casing 2 can be suitably gripped and has a small size. For example, the length L is smaller than 16 cm and preferably smaller than 11 cm. The width is generally constant, the thickness does not exceed 4 cm, and the average width is 0.6-2 cm, which is suitable for holding in the hand. The maximum height of the casing 2 does not exceed 6 cm.

  Referring to FIG. 1, the attachment head 3 protrudes through an opening 4 formed in the forefront portion of the casing 2, and determines the structure of the applicator 1. This assembly of the attachment head 3 in connection with the casing 2 allows the head 3 to slide along the longitudinal axis of the casing 2.

  As seen in FIG. 2, the application head 3 can be retracted, for example, completely retracted and protected inside the casing 2. Thus, the strip 5 is protected from damage or destruction. The strip 5 wound in the casing 2 serves as a support for the film of the member to be transported or for the patch. The strip 5 wraps around the end 3 a of the application head 3.

  The strip moving device 6 is known and can be housed inside the casing 2 to move the strip 5 over the deposition head 3. In FIGS. 1 and 2, which are non-limiting examples, the deposition head 3 and the strip moving device 6 are attached together. It is understood that the strip reel function can be achieved in different rules and is not described here in further detail. The strip moving device 6 comprises a gear, belt or similar member for winding the strip 5 following the path of the deposition head 3. The device 6 is a direct drive type device. The strip 5 is of any width, for example in the case of a correction applicator, approximately less than 1 cm.

  1 and 5 show the structure of the applicator 1, with the attachment head 3 protruding from the casing 2. In this position, the member can be transferred from the support strip 5 onto a sheet or any other suitable substrate (not shown). The length by which the strip protrudes from the casing 2 is limited to the short position in the usage form. This short position generally protrudes from the casing 2 by being bent back, and the delivery portion guided along the bottom 3a of the attachment head 3 before the position to be bent back, and the attachment head 3 after being bent back. And a feeding portion guided along the top portion 3b. The strip 5 is supported in a known manner by the thin end 3a of the deposition head 3 during the deposition of the member.

  In a preferred embodiment of the invention as shown in FIGS. 1 to 7, the attachment head 3 of the applicator 1 moves relative to the casing 2. This movement is limited by the guide member 7 and is controlled by a return device 8 that enables the displacement of the attachment head 3 between the forward position and the backward position corresponding to the use form. The return device 8 is connected, for example, to the casing 2 and the attachment head 3 and allows the attachment head 3 to be displaced between the proximal position and the distal position with respect to the casing 2 in the form of use. The strip 5 is guided in movement by one or more auxiliary rollers or auxiliary cylinders R connected to the casing 2.

  1, 2 and 5, the return device 8 comprises a first part fixed to the casing 2 and a second part fixed to the strip moving device 6. In a non-limiting manner, the displacement of the deposition head 3 is linear. In the form of use, the two parts of the return device 8 move away, but move closer to each other in the restricted width of the displacement, so that there is an initial position for the two parts. Interact with each other.

More specifically, the return device 8 forms a reference position x ₀ via the connection portion to the casing 2, its position is fixed during the displacement of the attachment head 3. The movable portion of the return device 8 is moved between the reference position x 2 two positions x _1, which is separated from the ₀ and x _2. In a non-limiting embodiment of Figure 1 and 5, the portion provided with the magnet M, for example when the member is force attachment head 3 by a substrate is attached is loaded, towards the minimum spacing position x ₁ Moving. Then, return device 8 generates a reaction force between the two parts, move the movable portion towards the position x ₂ is the maximum separation position. The position x ₂ corresponds to the initial position of the deposition head 3 in the usage mode of the applicator 1.

The above-described invention involves a reaction force that opposes compression or increased proximity. In less desirable variations, the reaction force can be generated in response to traction. Therefore, the initial position of the attachment head 3 in the use forms, corresponds to the minimum spacing of the position of the movable portion of the device 8 with respect to the reference position x _0. In this case, the reaction force is generated so as to move toward the position of minimum separation.

  Regardless of the embodiment of the return device 8, it is understood that when the applicator 1 is pulled out of the substrate at the end of the transfer, it will be understood that a sudden behavior is obtained, so that the return device 8 is distal to the attachment head 3. Designed to apply a reaction force toward the edges. The return device comprises a different structure, and the force loaded by the return device 8 results in a tendency to develop towards a more appropriate structure.

  The applied force corresponds to, for example, the repulsive force of the magnet between the two magnet members A and M of the return device 8. In this case, the first member A of these two magnet members comprises, for example, one or more magnets 10, 11 and is connected to the casing 2, while the second magnet member M moves the stripping head 3 and the strip. Connected to a movable element 12 comprising a device 6. The position of the element 12 in the casing 2 is advantageously controlled by the return device 8 and adjusted by the manual operating part of the return device 8.

  A first embodiment is described herein with reference to FIGS.

  As can be seen in FIGS. 1 and 2, the element 12 is assembled to slide in the casing 2. The second magnet member is, for example, a magnet M, and is attached to the rear portion of the strip moving device 6 by using the support 14 a of the support structure 14. As a variant, a more complex and / or rotational or other suitable displacement of the deposition head 3 can be obtained as long as there is a suitable guide in the casing 2.

  The first magnet member A is disposed in the actuation assembly with two adjustment settings. 1-3, the actuating member 23 corresponds to a knob that rotates about an axis orthogonal to the direction of the magnetic field, which magnetic field is at least one of the magnets 10, 11 and the attachment head 3 of the actuating assembly A. It can be formed with the magnet M connected to. The knob can be manually rotated and adjusted and rotated, for example, 180 ° between two operating positions. More generally, the actuating member 23 can be manually moved between a first position in which the usage pattern is activated and a second position in which the retracting pattern is activated. Although the actuating member 23 is described as rotating, its displacement can correspond to translation or a combination of translation and rotation, for example, helical movement.

  Referring to FIGS. 1 and 2, the support 14 a forms a housing for receiving the magnet M and has a concave surface that can come into contact with the convex surface associated with the magnet member A connected to the casing 2. The housing is located outside the element 12 and reduces its length. The housing is therefore arranged outside the plane defined by the direction in which the element 12 extends and the direction of the roller shaft. The casing 2 has a curvature that is easily gripped in the hand at the rear part.

  In this first embodiment, the magnet M connected to the attachment head 3 has diametrically opposite poles on the side facing the attachment head 3. In the embodiment of FIGS. 1 and 2, the magnet M comprises an N pole, which is parallel to the direction of displacement of the deposition head 3 and faces towards the magnet member A.

  In the mode of use shown in FIG. 1, the magnet 10 mounted in the actuation assembly has a north pole and faces the back side of the magnet M with the same pole (north pole). In other words, the magnets 10 and M are arranged facing each other, and in this method, the magnetic field lines are generated in opposite directions. Therefore, the lines of magnetic force are formed substantially parallel to the attachment head 3. As a result, the repulsive force moves the attachment head 3 toward the distal position with respect to the casing 2. In fact, excessive access of the magnets 10 and M in this case leads in particular to the unstable structure of the return device 8. This repulsive force is, for example, between 0.5 and 12N, preferably between 1 and 8N between the distal and proximal positions.

  Along with the magnet, this force further increases the proximity of the proximal position. In a less preferred variant (not shown), the return device 8 may use a spring, in particular a metal coil spring, instead of the magnets 10 and M to load the elastic restoring force. In this case, the spring is connected to the casing 2 at one end and to the attachment head 3 at the other end. The restoring force is directly proportional to the spring constant. Accordingly, a number of advantages of the use configuration with a magnet buffer shown in FIG. 1 are obtained by using an elastic buffer with a similar repulsive force loaded towards the distal position of the attachment head 3. .

  With reference to FIGS. 1 and 2, the amplitude of displacement of the attachment head 3 is between a distal position and a proximal position, for example between 2 and 10 mm, preferably about 7 mm. Therefore, the retracting operation of the attachment head 1 when the applicator 1 is pressed against the substrate causes a sudden movement when the pressing of the applicator 1 is interrupted, that is, when the user lifts the applicator 1. Enough. The displacement amplitude d of the attachment head 3 between the retracted form and the use form can be about 1 mm larger than the amplitude of the displacement at the time of buffering.

  As can be seen in FIGS. 1 and 2, the strip moving device 6 wraps and advances the strip 5 in use. One or more rollers on which the strip 5 can be wound are assembled in a support structure 14 and perpendicular to the direction in which the element 12 extends. The support structure 14 comprises a plurality of flat walls and guides the winding of the strip 5. One of these walls corresponds to the middle part of the section 15 and comprises a support 14a at the rear end and an attachment head 3 at the front end. The slide of the element 12 is guided at the front and rear ends by a plurality of parallel guide members 7 and is laterally offset in the strip moving device 6 with respect to the path of the strip 5. In the form of use of the applicator 1, the element 12 slides backwards and the restoration of the element 12 facing forward is limited by one or more stops 16 of the casing 2, which stops, for example in the openings 4. It is formed at the rear end of the guide member 7 disposed in the vicinity.

  Referring to FIG. 4, the stem 17 connects the attachment head 3 to the rest of the element 12. The stem 17 includes fins 18 or other projecting members, and can engage with a slit formed between two parallel guide members 7 formed as a part of the casing 2.

  Still referring to FIG. 4, the deposition head 3 can be flat at the free end, facilitating strip back bending. The attachment head 3 includes one or more upward or downward projections 19 (perpendicular to the direction of the slide) in the vicinity of the free end of the attachment head. In the non-limiting example of FIG. 2 corresponding to the retracted form of the applicator 1, the projection 19 engages at least one stop surface formed in the casing 2. Here, the two protrusions 19 formed on both sides of the attachment head 3 press the front surface of the guide member 7 on the plate, thereby restricting the backward movement of the attachment head 3.

  When the applicator 1 is in the retracted configuration as shown in FIG. 2, the magnet 11 in the actuating assembly has a substantially flat surface facing the rear side of the magnet M connected to the deposition head 3. When the rotation axis X of the knob for the actuating assembly is perpendicular to the displacement of the attachment head 3 and parallel to the rear side of the magnet M, the magnetic removal achieved by the rotation of the knob is the tensile force of the magnet 11. It is easier than having to overcome. The strip movement device 6 is associated with guide means, for example lateral grooves 22 in the casing 2 (FIG. 1) and side ribs arranged in the element 12 or the like. These guide means are designed so that the magnet M is in close contact with the magnet 11 at a position proximal to the attachment head 3 (FIG. 2). Accordingly, the protrusion 19 comes into contact with the corresponding stop surface 7 a of the guide member 7. In this case, magnets 11 and M can be as short as about 1 or 2 mm from each other. Alternatively, these two magnets 11 and M can be arranged in the retracted form of the applicator 1.

Since the S pole of the magnet 11 magnetically attracts the N pole of the magnet M, the element 12 can be moved from the usage configuration to the retracted configuration by simply rotating the knob. Thus, the element 12 is maintained in the retracted configuration. The restoration to the use form is possible only when the user operates the operating member 23 and the south pole of the magnet member A does not face the north pole of the magnet M.

  The illustrated magnets 10, 11, M are cylindrical and have a diameter of, for example, less than 15 mm, but of course any shape of magnet that can be accommodated in the casing 2 is equally suitable.

Since the attachment head 3 has the same mobility as the magnet M here, the knob is rotated around the axis X as shown in FIG. 2 to change from the magnetic attraction mode to the magnetic repulsion mode. It will be understood that the displacement of the magnet 11 is equivalent to the operation of displacing the attachment head 3 from the retracted position to the protruding position. Similar to that, as shown in FIG. 1, the displacement of the magnet 10 to be changed by rotating the knob about the axis X from the magnetic repulsion mode to magnetic attraction mode, save the attachment head 3 from the protruding position It will be understood that this corresponds to the movement to position.

  In the first embodiment, one or more magnets 10, 11 in the rotational adjustment motion assembly are present because there are two distinct surfaces, one forming the N pole and the other forming the S station. This minimizes the force that must be applied to be released from the magnetic attraction applied by the magnet M connected to the attachment head 3. The arrangement of the two magnets 10 and 11 respectively arranged on both sides of the rotating shaft allows the use of a common and inexpensive commercial magnet. Each of these two magnets 10 and 11 has a poled surface facing the rotation axis, one for attracting the magnet M and the other for repulsion of the magnet M. Of course, any other arrangement of one or more magnets can be used in the actuation assembly.

  In the non-limiting example of FIGS. 1-4, a 180 ° rotation of a knob or similar element changes from a retracted configuration to a use configuration. Each of the two positions of the knob is associated with a solid contact between the casing 2 and the knob and / or the shaft element of the knob. This makes it possible to maintain the knob in a fixed position despite the magnetic repulsion force applied to the magnet 10. Further, most of the knob can be accommodated in the casing 2. As shown in FIG. 3, the contact part 24 protrudes through the upper opening 25 of the casing 2 and represents at most a quarter of the periphery of the working part.

  A second embodiment is described herein in connection with FIGS.

  In this second embodiment, the applicator 1 comprises a return device 8 that continuously advances the deposition head 3 toward the distal portion of the deposition head. For this reason, the magnets 10 and M face the same magnetic pole. Compared with the first embodiment, the device 8 forms a magnet member facing the magnet M, in which the magnet 20 is connected to the attachment head 3, and there is a member for moving the attachment head 3 toward the repulsion position. It is different in that it is not. In order to apply a magnetic repulsion force to the magnet M, the magnet 20 is simply maintained in a fixed position relative to the casing 2.

  The mechanism for adjusting the repulsive force makes it possible to adjust the distance between the magnet 20 and the magnet M. In the embodiment shown in FIGS. 5 and 6, the movable member 31 of the adjustment mechanism extends laterally in the casing 2, for example, and is integrally attached to the magnet 20 for use in adjusting one of the magnets 20. Yes. Here, the movable member 31 has a free end protruding outside the casing. Thus, the user decreases or increases the forward force applied to the element 12.

  The rest of the second embodiment is generally similar to the first embodiment described above. In particular, the repulsive force can be within a numerical range of the same force. In addition, the stop 16 positions the distal position of the attachment head 3.

  A third embodiment is described herein in connection with FIGS. 7 and 8A and 8B.

  In this third embodiment, the element 12 can be identical to the two previously described embodiments except for the rear end. The support 14A can be replaced by a support (not shown) that does not extend beyond the rear surface of the magnet M connected to the deposition head 3. Furthermore, the magnet M can have more than one magnetic pole on the rear face F (bipolar face).

  Thus, as seen in FIGS. 8A and 8B, the magnet M connected to the attachment head 3 has a bipolar surface facing the bipolar surface of the rotating magnet 30 connected to the actuating member 23. The rotating magnet 30 includes the same surface facing the magnet M connected to the attachment head 3 in both the usage mode and the retraction mode.

  The surface of the rotating magnet has both an outward force line (N pole) and an inward force line (S pole). In particular, the rotating magnet 30 has at least two different regions offset in the angular direction with respect to the rotation axis X ′ of the magnet 30, one of which corresponds to N-bending and the other corresponds to the S pole. Yes. As shown in FIG. 8A, the retracted position similar to the position shown in FIG. 2 is obtained when the rotating magnet 30 has a force line opposite to the direction of the force line on the rear surface F of the magnet M.

  As shown in FIG. 8A, the rotating magnet 30 rotates about the geometric axis X ′ through the two magnets 30 and M. With this arrangement, the user can change from one configuration to another by rotating from left to right or from right to left. This twisting operation makes it easy to separate the two surfaces of the magnet 30 into a usage form. This is due to the fact that regions of opposite polarity are adjacent in each magnet 30 and M, and it is easier to break the magnetic attractive force than to pull the magnets apart.

  4 and 8B, the opposite polarity of the field lines between the magnet 30 and the magnet M makes the proximal position of the attachment head 3 unstable. Therefore, the return device 8 has a more stable structure due to the maximum distance between the magnet 30 and the magnet M. This separation remains limited due to the presence of the stop 16 (see FIG. 1). The separation can correspond to the amplitude d of the displacement of the attachment head 3.

  One of the advantages of the present invention is the mobility of the deposition head 3 in the use form, which helps to improve the quality of the mounting of the components on the substrate. In fact, the restoring action toward the advance / distal position of the attachment head 3 can facilitate the release of the material (as a result of the abrupt action the adhesive film is Actively contributing to destruction). This also makes it possible to eliminate any mechanism for mechanically locking the device in the use configuration. Another advantage of the present invention is that the design of the applicator 1 with the movable attachment head 3 can be simplified.

  It will be appreciated that the shapes and details of the embodiments described above can be used together or separately. It will be apparent to those skilled in the art that the present invention can be embodied in many other specific forms without departing from the scope of the claimed invention. In particular, the material forming the film or patch corresponds to at least one coating material, which is white or another color, or translucent (or transparent).

  Although the return device 8 is shown as being located at the rear of the applicator 1, other arrangements of the device are possible, and the device 8 can occupy a position closer to the front end rather than the rear end. The device 8 can also be offset laterally relative to the intermediate surface of the support structure 14 orthogonal to the strip 5. In some modified embodiments, the device 8 can be largely disposed outside the casing 2.

  In embodiments using magnets, the support 14a can be a removable attachment for the magnet M. Additionally or alternatively, the support 14a can be separated from the support structure 14. Thus, the strip 5 can be replaced because the other element 12 forms a compatible cartridge that can be removed from the casing 2 by the user. In order to remove this cartridge, the casing 2 comprises a manually removable part, which can be quickly attached to another casing 2.

  In the illustrated embodiment, there is a restoring function, and as a result, the actuating member 23 automatically moves to the use configuration. However, the magnet member can be changed from the retracted form to the used form regardless of the operation of the restoration function. As illustrated, the first actuating member contributes solely to the retracting or protruding of the deposition head 3, while the additional second actuating member enables the operation of the restoring function in the use configuration. For example, such a second actuating member can contribute to the choice between a first mode with a restoring force and a magnetic buffer and a second mode with immobilization of the attachment head 3 in the mode of use. Is possible. This second mode is suitable for fixing the head in a use form when used by a user who is formed on the applicator device.
