Description

  The present invention relates to a transfer tool in which a transfer portion protrudes from a housing when used and is inserted when not in use. In particular, the transfer portion is inserted into the housing even when the transfer portion is strongly pressed against a transfer target. Further, the present invention relates to a structure in which a member is not damaged even when used with such a strong force.

  A transfer tool for transferring a transfer medium to a transfer medium such as paper has as its main component a transfer shaft portion in which a transfer tape having a transfer medium coated on a base material is wound in a housing, and transfer of the transfer tape. A take-up shaft portion that winds the substrate after the medium is transferred to the transfer target, and a transfer portion that transfers the transfer medium of the transfer tape to the transfer target. In the following description, unless a transfer tape and a transfer medium are specifically described, the transfer tape on the sending side and the base material on the take-up side are collectively referred to as “transfer tape”.

  With the transfer tool, the transfer unit exposed from the housing is pressed against the transfer target body while moving the whole on the transfer target member, so that the relative movement between the substrate and the transfer target member is caused by the output of the transfer shaft part. It becomes the driving force (and the winding driving force of the winding shaft portion), the base material is pulled out from the sending shaft portion (the base material is taken up by the winding shaft portion), and at the transfer portion when this base material is transported The transfer medium on the substrate is transferred to the transfer target.

  Therefore, the transfer tool is exposed from the housing when the transfer unit is in use. However, if the transfer unit is left exposed, the transfer tape positioned on the transfer unit may be twisted, damaged or broken due to contact with the outside, The transfer medium of the tape sometimes adhered to the outside unintentionally.

  In view of this, a cover provided with a cover has been proposed. However, if the cover is completely separated from the housing of the transfer tool, for example, the cover may be lost.

  However, a transfer tool having a cover that can be opened and closed with respect to the transfer unit has a problem that it is difficult to use the transfer tool depending on the open position of the cover when the transfer tool is used in an open state. It was.

  Therefore, in recent years, as shown in Patent Documents 1 and 2, the cover is not provided, the transfer unit is retracted inside the case when not in use, and the transfer unit is exposed outside the case when in use. On the other hand, a transfer tool has been proposed in which a main body including a transfer portion is inserted and protruded.

  Patent Document 1 includes a main body case and an outer frame case. The main body case is slidable with respect to the outer frame case. The main body case includes a delivery shaft portion, a winding shaft portion, and a transfer portion. The outer frame case includes a fixing mechanism that fixes the transfer portion of the main body case to a protruding position from the outer frame case, and a stop mechanism that stops the transfer portion of the main body case at the storage position in the outer frame case. And a slide member that slides between the stop mechanism and the stop mechanism.

  In Patent Document 1, when the main body case is slid with respect to the outer frame case during use, the engagement of the driving member at the storage position by the stop mechanism is released, and the driving member is engaged at the fixing position by the fixing mechanism. When the transfer unit (main body case) moves and is not used, the transfer unit is pressed against the transfer target body, so that the engagement of the drive member at the fixed position by the fixing mechanism is released, and the drive member is moved at the storage position by the stop mechanism. The outer frame case moves relative to the transfer portion (main body case) by engaging.

  Patent Document 2 discloses a main body including a projecting opening formed at one end, a moving passage drilled on one side surface, and a plurality of positioning recesses recessed at both side walls of the moving passage. A positioning device that includes a moving device housed in the main body, a positioning portion that is perpendicular to the moving passage and is engaged with any of the plurality of positioning recesses, and that is interlocked with the moving device; Corresponding transfer section, delivery shaft section, take-up shaft section are mounted in conjunction with the moving device and accommodated in the main body, and slidably located in the movement path and moved It is described that a button for moving the moving device relative to the main body is provided by depressing the positioning portion of the positioning elastic member so as to be selectable in conjunction with the device so as to be separated from the positioning recess.

  In Patent Document 2, when the moving device is moved with respect to the main body in a direction in which the transfer unit protrudes from the main body by operating a button, the positioning elastic member is elastically deformed (the moving device is inserted into the main body). The moving device moves while being separated from the positioning recess (in a state of being moved), engages with the positioning recess after the positioning elastic member has moved, and operates the button when not in use to transfer the moving device to the main body. When the portion is moved in the direction of insertion into the main body, the positioning elastic member moves while being separated from the positioning recess (with the moving device protruding from the main body) with elastic deformation, and the positioning elastic member Engages with the positioning recess after moving.

  However, although Patent Documents 1 and 2 basically have a configuration in which a main body including a transfer portion is inserted into and protruded from a housing as described above, there are the following problems. Patent Documents 1 and 2 also require a force in both directions to move the main body including the transfer portion in both the protruding direction and the inserting direction. However, the transfer portion is used as a transfer target with the transfer portion protruding. When strongly pressed, the transfer part may be inserted into the housing due to the reaction force from the transfer target. In addition, when a force that causes the transfer unit to be inserted into the housing is applied, a part of the configuration may be damaged.

  As a result of considering the above-mentioned problems of Patent Documents 1 and 2, the present inventor, when moving the transfer part (and the main body including the transfer part) in both the protrusion and insertion directions, It was identified that there was a configuration that "maintained" but there was no configuration "facing" this force when a force was applied in the insertion direction.

JP 2009-83397 A JP 2012-139554 A

  The problem to be solved is that, in Patent Documents 1 and 2, when the transfer unit (and the main body including the transfer unit) is protruded from the housing and the transfer unit is strongly pressed against the transfer target, There is a point that it may be inserted into the housing, and a part of the member may be damaged when the transfer portion is inserted into the housing.

  The present invention includes a casing, a delivery shaft provided in the casing and wound with a transfer tape coated with a transfer medium on a base material, and the transfer medium of the transfer tape is transferred to a transfer target. A winding shaft that winds up the substrate afterwards, a drive gear provided on each of the feeding shaft and the winding shaft, and a transfer unit that transfers the transfer medium of the transfer tape to the transfer target are integrated. And an operating body that moves the main body in a direction in which the transfer unit protrudes from the housing and a direction in which the main body is inserted into the housing. A guide having a step is formed on one inner surface of both sides orthogonal to the axis of the shaft portion and the winding shaft portion, and the guide is elastically deformed at a portion corresponding to the one inner surface of the housing in the main body. Elasticity that comes into contact with the stepped portion while the elastic deformation is restored at the stepped portion. It is most important that a ride portion is formed, and that the operation body is formed with an operation rib for moving the main body via the elastic slide portion and preventing elastic deformation at the step portion of the elastic slide portion. Features.

  In the present invention, when the operation body is operated and the main body is moved with respect to the housing in the direction in which the transfer portion protrudes, the operation rib of the operation body contacts the stepped portion of the housing. Since the elastic slide portion of the main body in the state is prevented from being elastically deformed, the transfer portion is not inserted into the housing due to the contact of the elastic slide portion with the stepped portion, and the transfer portion is strongly attached to the transferred object. Since there is no room for the elastic slide portion to elastically deform even when pressed, the member is not damaged.

FIG. 1 is a main part configuration diagram showing a state in which a main body is inserted into a housing in a transfer tool of the present invention. FIG. 2 is a main part configuration diagram showing a state in which the main body protrudes from the housing in the transfer tool of the present invention. 3A is a perspective view showing a main body of the transfer tool of the present invention, and FIG. 3B is a perspective view showing a housing of the transfer tool of the present invention. FIG. 4A is a perspective view showing the front side of the operating body of the transfer tool of the present invention, and FIG. 4B is a perspective view showing the back side of the operating body of the transfer tool of the present invention. FIGS. 5A to 5D are diagrams showing a transition state from the unused state to the used state of the transfer tool of the present invention. FIGS. 6A to 6D are diagrams showing a transition state from the use state to the unused state of the transfer tool of the present invention.

  In the present invention, simply by moving the main body relative to the housing and maintaining the transfer portion at the exposed position, the transfer portion (including the main body) is moved into the housing when the transfer portion is strongly pressed against the transfer target. The problem that the operating rib of the operating body is in contact with the stepped portion of the casing is prevented by preventing the elastic deformation of the elastic sliding portion of the main body.

  That is, in the configuration of the transfer tool according to the present invention, when the operating body is operated, the main body protrudes from the housing with respect to the housing, and the transfer portion is inserted into the housing. When the operation is performed so that the main body protrudes from the housing, the operation ribs on the operating body do not only maintain the protruding state of the main body and the housing, but resist the force that the main body tries to insert and move into the housing. Therefore, the stepped portion and the elastic slide portion are in contact with each other and cannot move in this direction. In this way, even if the transfer portion is strongly pressed against the transfer object, the main body is not inserted into the housing and can be used stably.

  Further, the operation rib of the operation body is fitted into a space allowing the elastic deformation of the elastic slide portion in contact with the stepped portion when the transfer portion protrudes from the housing. As a result, the elastic slide portion can no longer be elastically deformed, and the reaction force from the transferred body can be received by the entire operation body and the main body, so that the member is not damaged and is durable. Rich.

As shown in FIG. 3A, the elastic slide portion 2Ac is in a state where the end portion in the counter-transfer portion direction is inclined obliquely upward as shown in FIG. The elastic slide portion 2Ac is elastically deformed substantially horizontally when a pressing force is applied to the inclined surface in the direction of the substrate 2B (downward).

  Further, an insertion abutting portion 2Ad is formed on the outer side of the guide ribs 2Aa and 2Aa, at a position within the winding diameter on the winding shaft portion 2b side, at a predetermined interval horizontally with the guide ribs 2Aa and 2Aa. Has been.

  The housing 3 is divided into two parts, that is, a side shown in FIG. 3B and a side (not shown), and an opening 3A is formed through which the transfer part 2d portion of the main body 2 enters and exits. Although the housing 3 on the side not shown has a functionally necessary configuration as the transfer tool 1, a characteristic configuration in the present invention is not provided, and thus the description is omitted together with the illustration.

  The housing 3 is formed with a wall surface 3a parallel to the transfer portion direction-anti-transfer portion direction at a portion corresponding to the outside (surface opposite to the facing surface) of the elastic slide portions 2Ac, 2Ac of the main body 2. . A guide 3c having a stepped portion 3b at the end in the direction of the transfer portion is formed at the opposite portion of the wall surface 3a. A contact portion 3d is formed at the end of the guide 3c in the direction opposite to the transfer portion.

  Further, the casing 3 is formed with an oval window portion 3e penetrating the front and back surfaces on a surface orthogonal to the axes of the delivery shaft portion 2a and the winding shaft portion 2b between the guides 3c and 3c. Yes. An engaging recess 3f is further formed in the direction from the position where the window 3e is formed to the counter-transfer portion.

  The operating body 4 is configured as shown in FIG. The operating body 4 has such a length that the entire length in the longitudinal direction (transfer portion direction-counter transfer portion direction) is completely accommodated in the housing 3, and the surface side shown in FIG. 4A is shown in FIG. The rear surface side shown in FIG. 4 (b) faces the surface on which the elastic slide portion 2Ac etc. of the main body 2 shown in FIG. 3 (a) is formed. Be placed.

  An operation button 4a that is viewed through the window 3e of the housing 3 is formed at the approximate center on the surface side of the operation body 4 shown in FIG. A stopper 4b is formed at the end of the operation body 4 in the direction opposite to the transfer portion (on the right side of the sheet) via a notch parallel to the transfer portion direction. This stopper 4b is elastically deformed up and down (front and back direction) by the notch. A boss 4c is formed on the surface portion of the stopper 4b.

  An insertion operation rib 4d and a projecting operation rib 4e are provided on the longitudinal side portion of the operation body 4 in a state of projecting from the transfer unit direction (left side of the paper) to both sides perpendicular to the transfer unit direction. The insertion operation ribs 4d and 4d are provided at substantially the tip portion of the operation body 4 in the transfer portion direction, and the protrusion operation ribs 4e and 4e are provided at substantially the center portion of the operation body 4 in the transfer portion direction-anti-transfer portion direction length. It has been. Further, concave portions 4f and 4f are formed on the surfaces of the projecting operation ribs 4e and 4e, respectively.

  The back surface of the operation body 4 shown in FIG. 4B has a concave groove 4g formed at the center in the width direction, and the front end portion (left side of the paper surface) of the concave groove 4g (operation body 4) in the transfer portion direction. A contact body 4h is formed.

  Next, the positional relationship of the main body 2, the housing 3, and the operation body 4 with respect to main parts will be described with reference to FIGS. 1 and 2. Note that some explanations are not shown because of the overlapping of the members. The upper surface of the elastic slide portion 2Ac of the main body 2 moves while contacting the guide 3c between the wall surfaces 3a of the housing 3. Further, the end portion of the elastic slide portion 2Ac in the anti-transfer portion direction of the elastic slide portion 2Ac in which a later-described transfer portion 2d protrudes from the case is in contact with the step portion 3b of the case 3.

  The operation button 4a of the operation body 4 is exposed from the window 3e of the housing 3, and the boss 4c is fitted into the engagement recess 3f in which the transfer portion 2d is inserted into the housing. Further, the guide rib 2 </ b> Aa of the main body 2 is inserted into the concave groove 4 g of the operation body 4. The contact body 4h of the operating body 4 contacts the moving contact portion 2Ab of the main body 2 when the transfer portion 2d is inserted into the housing.

  The insertion operation rib 4d of the operation body 4 moves on the transfer portion direction side of the elastic slide portion 2Ac in accordance with the operation direction of the operation body 4 in the transfer portion direction and the counter-transfer portion direction. When the transfer portion 2d is inserted into the housing, the insertion operation rib 4d is elastically deformed by pressing the upper surface of the elastic slide portion 2Ac close to the horizontal with the substrate 2A while climbing the inclination of the elastic slide portion 2Ac. When the transfer portion 2d protrudes from the housing, the insertion operation rib 4d is released from the elastic slide portion 2Ac by releasing the pressing force of the elastic slide portion 2Ac while descending the upper surface of the elastic slide portion 2Ac.

  The protruding operation rib 4e of the operation body 4 moves between the elastic slide portion 2Ac and the insertion contact portion 2Ad of the main body 2 in accordance with the operation direction of the operation body 4 in the transfer portion direction and the counter-transfer portion direction. When the transfer portion 2d is inserted into the housing, the protruding operation rib 4e contacts the insertion contact portion 2Ad, and when the transfer portion 2d protrudes from the housing, the protruding operation rib 4e changes as described later. Finally, the elastic slide portion 2Ac is positioned below the end portion of the elastic slide portion 2Ac in the anti-transfer portion direction, and the elastic slide portion 2Ac is engaged with the concave portion 4f of the protruding operation rib 4e.

  The operation of the transfer tool 1 having the above configuration will be described with reference to FIGS. FIGS. 5A to 5D show a state where the main body 2 is sequentially inserted from the state inserted into the housing 3 and protruded. FIG. 5A shows a state in which the main body 2 is completely inserted into the housing 3. At this time, the operation button 4 a of the operation body 4 is positioned at the end of the window 3 b of the housing 3 in the direction opposite to the transfer portion, and the boss 4 c of the stopper 4 b of the operation body 4 is engaged with the engagement recess 3 f of the housing 3. Is fitted. Further, the insertion contact portion 2Ad of the main body 2 is in contact with the contact portion 3d of the housing 3.

  Further, the projecting operation rib 4e of the operation body 4 is in contact with the guide rib 2Aa in the main body 2 and is located away from the elastic slide portion 2Ac in the direction opposite to the transfer portion. The insertion operation rib 4d of the operating body 4 rides on the elastic slide portion 2Ac so that the upper surface of the elastic slide portion 2Ac comes into contact with the guide 3c of the housing 2 on the slope of the elastic slide portion 2Ac in the main body 2 in the inserted state. 2Ac is elastically deformed. Further, although not shown in FIG. 5A, the end of the contact body 4h of the operating body 4 in the direction opposite to the transfer portion and the end of the moving contact portion 2Ab of the main body 2 in the direction of the transfer portion contact each other. Yes.

  When the operation button 4a is operated in the direction of the transfer portion from the above state, as shown in FIG. 5B, the boss 4c of the operation body 4 and the engagement recess 3f of the housing 2 are moved as the operation body 4 moves. Disengagement occurs, the projecting operation rib 4e of the operating body 4 pushes the elastic slide portion 2Ac of the main body 2 toward the transfer portion, and the insertion operation rib 4d releases the pressure of the elastic slide portion 2Ac, that is, the elastic slide portion 2Ac. Get off the slope and move toward the transfer section.

  When the protruding operation rib 4e of the operating body 4 pushes the elastic slide portion 2Ac of the main body 2 in the direction of the transfer portion, the elastic slide portion 2Ac of the main body 2 is moved to the guide 3c of the housing 3 as shown in FIG. A path that moves in an elastically deformed state is removed and reaches the stepped portion 3b. When the elastic slide portion 2Ac reaches the step portion 3b, the elastic slide portion 2Ac that has been elastically deformed until then and has become substantially horizontal is elastically restored to a natural state.

  Further, when the operation button 4a of the operating body 4 is moved toward the transfer portion and the operation button 4a comes into contact with the end portion of the window 3e of the housing 3 in the transfer portion direction, as shown in FIG. Further, the projecting operation rib 4e of the operating body 4 enters the lower portion of the elastic slide portion 2Ac of the main body 2, and the lower surface of the end of the elastic slide portion 2Ac in the direction opposite to the transfer portion and the recess 4f of the projecting operation rib 4e are engaged. To do.

  As a result, the main body 2 is not inserted into the housing 2 even if the transfer portion 2d is strongly pressed against the transfer target body, unless the operation button 4a of the operation body 4 is operated in the direction of the counter-transfer portion. This is because the elastic slide portion 2Ac of the main body 2 is in contact with the step portion 3b of the housing 3, so that the main body 2 does not move toward the anti-transfer portion, and elastic deformation of the elastic slide portion 2Ac is allowed. This is because the protruding operation rib 4e enters the space to be moved, and the elastic slide portion 2Ac is not elastically deformed.

  Therefore, the transfer tool 1 of the present invention is configured even when the transfer portion 2d is strongly pressed against the transfer target, the main body 2 is inserted into the housing 2, or such a strong force is applied. The member is not damaged.

  On the other hand, when the transfer part 1 of the main body 2 is inserted from the state shown in FIG. 5D where the transfer part 2d of the main body 2 protrudes from the case 3 into the case 3, the transfer tool 1 is shown in FIGS. 6A to 6D. Works as shown. As shown in FIG. 6A, when the transfer portion 2d of the main body 2 protrudes from the housing 3, the protruding operation rib 4e of the operating body 4 enters the lower portion of the elastic slide portion 2Ac of the main body 2, and the elasticity The lower surface of the end portion of the slide portion 2Ac in the direction opposite to the transfer portion is engaged with the concave portion 4f of the protruding operation rib 4e. At this time, the operation button 4 a is in contact with the end portion of the window 3 e of the housing 3 in the transfer portion direction. That is, this is the state shown in FIG.

  Thereafter, as shown in FIG. 6B, when the operation button 4a of the operating body 4 is moved in the direction opposite to the transfer portion, the elastic body is moved to the lower part of the elastic slide portion 2Ac of the main body 2 in contact with the step portion 3b of the housing 3. The protruding operation rib 4e of the operation body 4 that has been positioned moves from the position toward the counter-transfer portion. At this time, elastic slide part 2Ac will be in the state which can be elastically deformed.

  Furthermore, when the operation button 4a of the operating body 4 is moved in the direction opposite to the transfer portion, the contact body 4h of the operating body 4 and the moving contact portion 2Ab of the main body 2 come into contact with each other as shown in FIG. The main body 2 is moved in the direction opposite to the transfer portion, and the insertion operation rib 4d of the operating body 4 rides on the slope of the elastic slide portion 2Ac of the main body 2 so that the elastic slide portion 2Ac is substantially horizontal, It is elastically deformed so that it can be inserted into the space of the guide 3c.

  When the operation button 4a of the operation body 4 moves until it comes into contact with the end of the window 3e of the housing 3 in the direction opposite to the transfer portion, the elastic slide portion 2Ac of the main body 2 is moved as shown in FIG. In a state of being elastically deformed by being pressed against the insertion operation rib 4d of the operating body 4, the inside of the guide 3c of the housing 3 is moved in the anti-transfer direction, and the boss 4c of the stopper 4b of the operating body 4 is engaged with the engaging recess of the housing 3 Further, the insertion contact portion 2Ad of the main body 2 is brought into contact with the contact portion 3d of the housing 3, and the state shown in FIG.

  In the transfer tool 1 in the state of FIG. 6D, the boss 4 c of the operation body 4 and the engagement recess 3 f of the housing 3 are engaged unless the operation button 4 a of the operation body 4 is moved in the direction of the transfer section. Therefore, the main body 2 does not protrude from the housing 3 even if, for example, the transfer portion 2d is directed downward or the transfer portion 2d is swung around the tip.

  As described above, the present invention is a transfer tool 1 that inserts and protrudes the main body 2 with respect to the housing 3, and is in a protruding state even when the transfer portion 2 d is pressed strongly against the transfer target. Then, since the protruding operation rib 4e enters the space allowing the elastic deformation of the elastic slide portion 2Ac, the member is not damaged, and the protruding operation rib 4e enters the lower portion of the elastic slide portion 2Ac. Since the elastic slide portion 2Ac is in contact with the step portion 3b, the main body 2 is in the housing 3 because the elastic deformation is not allowed and there is no space for elastic deformation and movement in the anti-transfer portion direction. There is no insertion.
