Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a writing instrument with a seal stamp.

[0002]

2. Description of the Related Art Conventionally, as writing instruments with a seal stamp of this type, utility model registration numbers 2525535 and 2519 are available.
819 and the like. In the writing instruments with seals described in these publications, a cap is fitted on the outer periphery of the rear shaft so as to be able to move in the axial direction, and when the cap is rotated with respect to the front shaft, a plurality of caps in the front shaft are provided. Each of the cursive bodies can alternately appear and disappear from the tip hole of the tip shaft. A seal is provided in the rear end of the rear shaft, and a lid is attached to the top opening of the cap to open and close the opening.The lid is attached by a spring to automatically close the opening. It is energized. When a seal is used, the cap is moved forward with respect to the rear shaft, so that the cover around the seal provided in the rear end of the rear shaft presses the lid to open the cap. The seal can be imprinted by protruding the seal from the rear part.

The cap is locked in the front retracted position with respect to the rear shaft, for example, the utility model registration No. 2525.
In No. 535, a lever provided with a push button is pivotally attached to a clip, and an engagement protrusion provided on the lever is engaged with either of two engagement grooves provided on a side surface portion of the rear shaft. It has become. In this way, the cap is locked to the rear shaft when the seal stamp projects from the opening of the cap and when the lid closes the opening of the cap. In addition, for example, the utility model registration No. 2519819.
In No. 2, the locking projection provided on the side surface of the cylindrical cam integrally provided inside the rear shaft communicates with the rectangular window provided on the side surface of the cap. It is designed to be locked to one of the two protrusions. In this way, the cap is locked to the rear shaft when the seal stamp projects from the opening of the cap and when the lid closes the opening of the cap.

[0004]

That is, in the above-mentioned conventional writing instrument with a seal stamp, since the cap is configured to move in the axial direction with respect to the rear shaft, for example, the seal stamp is pressed against the paper surface while holding the cap. At times, it is necessary to lock the cap to the rear shaft so that the seal does not retract with the rear shaft. Similarly, even when the lid axially attached to the cap closes the opening, the cap is locked to the rear shaft so that the cap does not drop against the rear shaft and the seal is not exposed. There is a need to.

Since the mechanism for locking is provided as described above, in the utility model registration No. 2525535, when the cap is moved with respect to the rear shaft, the push button must be pushed to release the locking. However, there is a problem that the operation is troublesome. Also, in the utility model registration No. 2519819, if the locking is too weak, it is useless, but if the locking is too strong, it becomes difficult to move the cap with respect to the rear shaft. , There is a problem. The present invention has been made in view of the above problems, and an object of the inventions of claims 1 to 3 is to provide a writing instrument with a seal stamp capable of smoothly performing a feeding operation of a seal stamp.

[0006]

In order to achieve the above object, the writing instrument with a seal of the invention according to claim 1 of the present invention is connected to a barrel and a barrel so as to be rotatable relative to the barrel. The center cylinder, the rear cylinder connected to the center cylinder so as to be rotatable relative to each other, the seal provided so that it can be fed out from the rear end of the rear cylinder, and its tip can protrude from the front end of the front cylinder. The stamp extruding unit that rotates integrally with the cursive body provided in the center shaft cylinder and moves in the axial direction while moving spirally in the rear shaft cylinder by the relative rotation between the center shaft cylinder and the rear shaft cylinder. A slider and a writing body advancing mechanism for advancing the writing body in the axial direction by relative rotation between the front barrel and the center barrel.

When relative rotation is generated between the center barrel and the rear barrel, the seal stamp push-out slider advances the seal in the axial direction while moving spirally in the rear barrel. As a result, the seal can be fed from the rear end side of the rear barrel and used. Even if the stamp is pressed against the paper surface, the stamp pushing slider only moves spirally in the rear barrel and does not move linearly in the axial direction, so that the stamp pushing slider and the stamp do not retract. When relative rotation is generated between the front barrel and the center barrel, the writing body advancing mechanism moves the writing body in the axial direction. As a result, the writing body can be used by protruding from the tip end side of the front barrel.

According to a second aspect of the present invention, in the first aspect of the present invention, a lid rotatably supported on the rear end side of the rear barrel around the first rotating shaft orthogonal to the axial direction so as to be opened and closed. When,
A guide stopper that is slidable in the axial direction with respect to the rear barrel and a stamp receiver that holds the stamp and is connected to the stamp pushing slider are provided, and one end of the guide stopper has the first rotating shaft. Is supported by the lid at a second rotation axis parallel to the seal, the seal receiving member is lightly engaged with the guide stopper in a state where the seal is retracted, and the seal receiving member is extended in the axial direction. When the seal stamp is received, the guide stopper slides in the axial direction to move the second rotating shaft in the axial direction to swing the lid around the first rotating shaft. The engagement with the guide stopper is released, and the seal stamp is independently fed from the guide stopper.

When relative rotation is generated between the center shaft cylinder and the rear shaft cylinder, the seal stamp pushing slider moves in the axial direction while moving spirally, and the seal stamp receiver moves together with the seal stamp pushing slider. Since the seal stamper is lightly engaged with the guide stopper when the seal stamper is retracted, when the seal stamper is extended, the seal stamper and the guide stopper slide in the axial direction with respect to the rear barrel. Move. As a result, the second rotation shaft moves in the axial direction, the lid rotates about the first rotation shaft, and the rear end side of the rear barrel is opened. Further, when the seal stamp receiving member is extended, the engagement between the seal stamp receiving member and the guide stopper is released, so that the seal stamp receiving member is independently extended from the guide stopper, and the seal stamp sufficiently protrudes from the rear barrel.
When the stamp receiving member is retracted, the seal is retracted by the reverse operation, and the lid closes the rear end side of the rear barrel.

According to a third aspect of the present invention, in the first or second aspect, the writing body advancing mechanism has a cam inclined surface formed on the center cylinder and a projection engaging with the cam inclined surface. And the projection is provided on a writing body receiver that rotates integrally with the tip barrel and moves axially integrally with the writing body. When a relative rotation is generated between the center barrel and the front barrel, the projection that rotates integrally with the front barrel moves along the cam inclined surface, and the writing body receiver and the writing body move in the axial direction.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. In the figure, a writing instrument 10 with a seal stamp
Includes a front barrel 12, a center barrel 14 that is rotatably connected to the front barrel 12, and a rear barrel 16 that is relatively rotatable to the center barrel 14. Tip barrel 1
The front end of 2 is a front tool 12a screwed integrally with the main body of the front barrel 12. In the present embodiment, in order to make it possible to replace the refill 18 which is a cursive body described later, the tip 1
Although 2a is separable from the main body, the present invention is not limited to this, and the tip tool 12a can be formed integrally with the main body of the front barrel 12. A refill 18, which is a writing body, is provided inside the front barrel 12, and the tip of the refill 18 projects from a tip opening of a tip 12a of the front barrel 12 by a writing body advancing mechanism 24 described later. It is possible. The refill 18 is biased rearward by a return spring 19. The rear portion of the refill 18 is fitted and inserted into the writing body receiver 20, and the rear end of the refill 18 is in contact with the rear end portion of the writing body receiver 20. The writing body receiver 20 is urged rearward by a second return spring 22 provided between the writing body receiver 20 and the step portion 12b of the front barrel 12 and is formed on the inner peripheral surface of the rear portion of the front barrel 12. The key 20b fitted into the key groove 12c is adapted to rotate integrally with the front barrel 12.

Further, the writing body receiver 20 causes relative rotation between the front barrel 12 and the center barrel 14, so that the writing body advance mechanism 24 advances the inside of the center barrel 14.
It is possible to retreat. That is, the cursive body receiver 20 is provided with a cam protrusion 20a on the peripheral surface of the substantially middle portion thereof, and the cam protrusion 20a is locked to the cam inclined surface 14a formed on the inner peripheral surface of the center rod cylinder 14. ing. FIG. 3C shows a development view of the cam inclined surface 14a. When the cam projection 20a is located at the rearmost portion 14b of the cam inclined surface 14a, the writing body receiver 20 and the refill 18 are retracted as shown in FIG.
And the refill 18 will advance as shown in FIG.

The rear portion 14d of the center barrel 14 is fitted in the seal pushing slider 26. By fitting the key 14e formed on the outer peripheral surface of the rear portion 14d and the key groove 26a formed on the inner peripheral surface of the stamp pushing slider 26, the center cylinder 14 and the stamp pushing slider 26 rotate integrally. It is supposed to do. A protrusion 26b is formed on the outer peripheral surface of the tip of the stamp pushing slider 26, and the protrusion 26b is
It is fitted in a spiral groove 16 a formed on the inner peripheral surface of the rear barrel 16. By moving the protrusion 26b along the spiral groove 16a, the stamp pushing slider 26 can move in a spiral shape in the rear barrel 16. A stamp receiver 28 is connected to the rear end of the stamp pushing slider 26 so as to be relatively rotatable. A seal stamp holder 30 is further connected to the seal stamp receiver 28, and the seal stamp holder 30 holds an ink permeation type seal stamp 34 together with a seal stamp cover 32. The seal receiving member 28 has a protrusion 28a on its side surface, and this protrusion 28a is slidably fitted in a sliding hole 38a of the guide stopper 38.

The guide stopper 38 is accommodated in a portion of the rear barrel 16 in the circumferential direction where the boring is large,
It is slidable with respect to the rear barrel 16. As shown in FIG. 6, the sliding hole 38a of the guide stopper 38 has a wide width at both ends 38b and 38c and a narrow width at an intermediate portion 38d. Then, while the protrusions 28a of the seal receiving member 28 are just fitted well at the end portions 38b and 38c, there is resistance to the movement from the end portion 38b or the end portion 38c to the intermediate portion 38d, and the protrusion 28a. Is not free to move from the end 38b or 38c to the intermediate portion 38d. As a result, the protrusion 2
8a is an end portion 38b of the guide stopper 38.
(Or 38c) will be lightly engaged. Further, during the movement of the protrusion 28a in the middle portion 38d, the protrusion 28a moves while receiving resistance, and in particular, the middle portion 38d has a narrow central portion that is most easily spread, A constant resistance force is applied to the protrusion 28a.

One end 38e of the guide stopper 38 is extended, and an insertion hole 38f is formed in the one end 38e into which a pivot pin which will be described later as a second rotation shaft 46 is inserted. The rear barrel 16 has a lid 4 for opening and closing one end side provided with the seal 34.
2 is attached. An insertion hole 42b orthogonal to the axial direction is formed in the base portion 42a of the lid 42, and the pivot pin inserted in the insertion hole 42b serves as the first rotation shaft 44, and the first rotation shaft 44 is centered. Is supported by the rear barrel 16 such that one end of the rear barrel 16 can be opened and closed. Also, the lid 4
One end 38e of the guide stopper 38 is pivotally supported on the second base portion 42a by a pivot pin inserted into the insertion hole 42b, and the pivot pin constitutes a second rotation shaft 46.

The operation of the writing instrument with a seal stamp constructed as described above will be described below. First, when writing, the center barrel 14 is rotated in a certain direction with respect to the front barrel 12 from the state in which the refill 18 is stored. This allows
The cam projection 20a of the writing body advancing mechanism 24 starts from the rearmost portion 14b, moves on the cam inclined surface 14a, and reaches the frontmost portion 14c. As a result, as shown in FIG. 2, the refill 1 is moved by the axial distance between the rearmost portion 14b and the frontmost portion 14c.
8 moves forward with respect to the front barrel 12, and the tip of the refill 18 projects from the tip 12a of the front barrel 12 for writing. Further, when the refill 18 is stored, by rotating the center cylinder 14 in the opposite direction, the reverse operation occurs, and the refill 18 retracts.

Next, when the seal 34 is used, the center barrel 14 is rotated with respect to the rear barrel 16. As shown in FIG. 1, when the center cylinder 14 is rotated in a certain direction from the state in which the lid 42 is closed, the protrusion 26 b of the stamp push-out slider 26, which is prevented from rotating with the center cylinder 14, has the spiral groove of the rear cylinder 16. 16
Along the line a, the axial direction is moved to the left in the figure, and the seal stamp 28 is pushed out in the same direction. Protrusion 28a of the seal receiving member 28
Is positioned at the end portion 38b of the guide stopper 38 with the seal 34 retracted, and is lightly engaged at that position as described above, the guide stopper 38 is shown in FIG. As described above, it moves leftward L together with the seal receiving member 28. Thus, the guide stopper 38
The second rotation shaft 46 moves leftward L together with one end 38e of the first rotation shaft 38e, and the base 42a of the lid 42 is fixed to the first rotation shaft 44.
Around the center of the drawing and rotates clockwise in the figure to open the rear end side of the rear barrel 16. Further, when the center cylinder 14 continues to rotate, the lid 42 is restrained by the first rotating shaft 44, and the guide stopper 38 cannot move further leftward. Moves out of engagement with the end portion 38b of the guide stopper 38 to the intermediate portion 38d and slides in the sliding hole 38a. At this time, the intermediate portion 38d has a narrow width, and since the protrusion 28a is tightened from both sides, the seal holder 28 can move straight in the axial direction by L2 without wobbling. In this way, the seal stamp 28 is independently fed from the guide stopper 38, and the seal stamp 34 is fed together with the seal stamp 28. When the protrusion 28a of the seal receiving member 28 reaches the end portion 38c of the sliding hole 38a, the resistance from the intermediate portion 38d is released, so that the operator can feel a moderation. The stamp receiving member 28 is again engaged with the guide stopper 38 to be in the state shown in FIG. 5, and in this state, the stamp 34 can be pressed toward a desired place for stamping.

When storing the stamp 34 after use, the center cylinder 14 is rotated in the opposite direction to the tip. As a result, the seal stamp receiver 28 moves to the right in the figure, and the protrusion 28a engaged with the end portion 38c of the sliding hole 38a of the guide stopper 38 moves to the intermediate portion 38d of the sliding hole 38a. At this time, the guide stopper 38 may move together with the seal receiving member 28 while the protrusion 28a remains engaged with the end portion 38c, but it is preferable that the guide stopper 38 be provided between the lid 42 and the pivot pin that is the first rotation shaft 44. Guide stopper 3 by friction
8 is stationary together with the lid 42, and the projection 2 of the seal stamp 28
It is desirable that 8a moves in the sliding hole 38a of the guide stopper 38. Then, after the protrusion 28a of the seal stamp 28 reaches the end portion 38b of the sliding hole 38a of the guide stopper 38, the guide stopper 38 moves rightward L together with the seal stamp 28. As a result, the second rotation shaft 46 moves rightward L together with the one end 38e of the guide stopper 38.
The base portion 42a of the lid 42 rotates counterclockwise in the figure around the fixed first rotating shaft 44 to close one end side of the rear barrel 16.

Since the rear barrel 16 and the center barrel 14 do not move relative to each other in the axial direction, there is no need to provide a mechanism for locking them, and there is no need to release the locking, so the operation is smooth. Can be done. At the time of imprinting, if the stamp 34 is pressed against the paper surface while pressing the rear barrel 16 (the center barrel 14 or the front barrel 12) by hand, the stamp pushing slider 26 receives a force in the axial direction in the retracted direction. However, the seal push-out slider 26 rotates integrally with the center cylinder 14,
Since it cannot move linearly in the axial direction with respect to the rear barrel 16, it will not retract. Further, the opening and closing of the lid 42 and the feeding out of the seal stamp 34 are performed independently, and the seal stamp 34 is not configured to push the lid 42 open, so that the lid 42 does not touch the seal stamp 34 and become dirty.

[0020]

As described above, according to claims 1 to 3,
According to the invention described above, by the relative rotation between the center barrel and the rear barrel, the seal push-out slider is provided for feeding the seal in the axial direction while moving spirally in the rear barrel, and the rear barrel and the middle barrel are provided. Since the cylinder and the cylinder do not move relative to each other in the axial direction, it is not necessary to provide a mechanism for locking them and an operation for releasing the locking is also unnecessary. Therefore, the operation of feeding out the seal can be smoothly performed.

Further, according to the second aspect of the invention, both opening and closing of the lid and feeding of the seal can be performed by relative rotation of the rear barrel and the center barrel, and opening and closing of the lid and feeding of the stamp. Because it is done independently, the lid does not touch the seal and get dirty. Further, since there is no need for a spring or the like for holding the lid closed or the lid open, it is not necessary to adjust the spring force, and the manufacturing can be performed at low cost.
