A refill groove is disposed inside the shaft body so as to be able to move back and forth freely. At the front end of the refill groove, a chuck body for sending the refill forward is fixed. In addition, the collet collar is wound around the front part of the collet body, and the opening and closing of the collet body is performed. Further, a pen head member is fixed to the front end of the shaft body, a pen core insertion hole is formed in the pen head member, and a slide member that has been pressed into the pen core non-return member is arranged, and the slide member can appear at the tip of the pen head member. However, the above-mentioned past technology may cause a gap between the rear end of a short refill (hereinafter, referred to as a residual core) detached from the chuck body and the front end of a subsequent new refill (hereinafter, referred to as a subsequent core). The reason is that before the collet body completes the backward movement, the collet is closed with the collet collar, and the collet is retracted while holding the subsequent core, so the shortened residual core at this time will be in an independent state from the subsequent core. , And is in a state of simply holding the refill non-return member in the nib member, without retreating. Then, when the aforementioned gap is generated, the remaining core is retreated due to the pressure of the writing pen when writing, which causes a writing error and an uncomfortable feeling. In addition, to remove the residual core from the guide member for smooth writing, and then extend it (please read the precautions on the back before filling this page). ) A4 specification (210X297mm) -4-580458 A7 B7 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs. 5.

A refill groove 2 is disposed inside the shaft body 1 so as to be able to move back and forth, and a chuck body 5 that can be switched by the relay member 3 and the refill guide member 4 is fixed to the front end of the refill groove 2. A front portion of the chuck body 5 surrounds a chuck collar 6 capable of performing switching of the chuck body 5. In addition, at the front end of the shaft body 1, the pen head member 9 is fixedly attached and detached by means such as a screw lock between the press-in member 7 and the connecting member 8. However, the pen head member 9 may be integrally formed with the shaft body 1. . A slide member 10 is disposed inside the pen head member 9 so as to be able to move back and forth, and a refill check member 11 formed of a rubber-like elastic body slightly holding the pen core is pressed into the slide member 10. Figure 12 shows a refill protective tube made of a metal material, which is pressed into and fixed to the front end of the sliding member 10, but may be formed integrally with the sliding member. However, the reference number S is an elastic member such as a coil spring that biases the chuck body 5 or the refill groove 2 to the rear. In addition, although the shaft of the automatic pencil of the product of the present embodiment is formed of a transparent material, the sliding member, the refill check member, etc. may be formed of a transparent material. This transparent material confirms the movement of the refill. Next, the chuck body 5 and the sliding member 10 will be described in detail. An outer crotch portion 13 is formed on the outer periphery of the front end of the chuck body 5. In addition, a cylindrical portion 14 is formed to extend rearward of the sliding member 10, and an inner surface crotch portion that is in contact with the outer crotch portion 13 of the front chuck body 5 is formed on the inner surface of the rear end of the cylindrical portion 14 1 5.

Description of Invention (11) Head Office The structure is a so-called collet chuck; when it is firmly closed in the state of holding the refill, the outer crotch portion 13 of the collet body 5 is removed from the inner crotch portion of the sliding member 10 1 5 protruded structure. That is, the chuck body 5 and the sliding member 10 can be separated or combined. In addition, the aforementioned sliding member 10 is inserted into the pen tip member 9 without applying friction resistance. However, the frictional resistance is set to be smaller than that of the refill non-return member holding the refill slightly. Preventing the movement of the sliding member 10 when the pen core is not clamped can prevent the movement sound of the sliding member 10 when the body is shaken (the middle section of the sliding member abuts against the inner surface section of the pen head member Ministry of Sound) and so on. Further, an inner surface section 17 is formed in front of the inner surface of the pen tip member 9 to abut the front end surface of the sliding member 10 and regulates the advancement amount of the sliding member 10. Next, the operation will be described. The state of FIG. 2 is a state where the residual core A deviating from the chuck body 5 is clamped by the refill check member 11 and the subsequent core B is clamped by the chuck body 5. When the lead core groove 2 is pushed to the front in this state, the chuck body 5 and the chuck collar 6 advance together, and the subsequent core B clamped also advances. As the subsequent core B advances, the residual core A is advanced, and the residual core A also advances. However, since it is held by the refill check member 1 1, the aforementioned sliding member 10 and the residual core A are advanced together. Here, the middle segment portion 16 of the sliding member 10 is abutted against the inner surface segment portion 17 of the aforementioned pen tip member 9, and the forward movement of the sliding member 10 is regulated. As a result, the refill protective tube 12 fixed to the slide member 10 is advanced relative to the pen head member 9 so that the length protruding from the tip of the pen head member 9 is larger than the initial state.

Description of the invention (12) 〇 In addition, if the refill slot 2 is further advanced, the residual core A moves forward To the refill protection tube 12 which is pushed into the subsequent heart B and prevented from moving, it protrudes and protrudes from its tip. Then, the aforementioned collet collar 6 abuts against the rear end of the aforementioned sliding member 10, regulates its forward movement, opens the collet body 5 and releases the subsequent core B. Here, when the forward movement of the lead core groove 2 is released, the chuck body 5 moves backward in a state where the subsequent core B is released, but after that, the outer crotch portion 1 3 of the chuck body 5 abuts against the sliding member 1 The inner crotch portion 15 of 0 also retracts the sliding member 10. At this time, the residual core A is slightly clamped by the refill holding member 1 1 of the sliding member 10, so that the protruding state of the residual core A is maintained while retreating from the sliding member 10, and the chuck body 5 is also used. The released core B moves backward. Then, the chuck body 5 is closed by the chuck collar 6 and retracts while holding the subsequent core B. However, as described above, the residual core and the sliding member 10 are retracted together, so that no gap is generated between the subsequent core B and the residual core A. In addition, through the above-mentioned operation, the residual core A moves backward, but since it moves backward with respect to the pen head member 9 with the sliding member 10, it does not move backward with respect to the pen core protection tube 12 (sliding member 10), so it does not The length protruding from the refill protective tube 12 is reduced.

Description of the invention (13) The part 15 applies friction resistance. An example of applying this friction is to form the outer diameter of the front outer peripheral surface of the chuck body 18 so that it is larger than the inner diameter of the inner surface of the sliding member 15 of the sliding member. In addition, the contact surface of at least one A rubber-like elastic body or the like may be used, or creping processing or the like may be applied. The operation will be described next. In the initial state (a state in which the collet body 18 is holding the refill: refer to FIG. 3), the front outer peripheral surface of the collet body 18 abuts on the inner surface of the sliding member 10 on the inside of the crotch portion 15. Here, when the chuck body 18 is advanced (together with the chuck collar 6), the chuck body 18 and the inner surface 锷 15 are brought into contact with each other by frictional resistance, so that the sliding member 10 is also advanced. Of course, the residual core A held by the refill check member 11 and the subsequent core B held by the chuck body 18 also advance. Further, as the chuck body 18 and the sliding member 10 move forward, the middle section portion 16 of the sliding member 10 abuts against the inner surface portion 17 of the pen head member 9 as in the first example described above, and is prevented. The slide member 10 moves forward (see FIG. 4). However, since the chuck body 18 can advance further, the abutment between the chuck body 18 and the inner surface crotch portion 15 of the sliding member 10 is relieved by the aforementioned frictional force, but the chuck body 18 is more advanced. Advance, so the residual core A advances into the refill protection tube that regulates the forward movement. Then, the aforementioned collet collar 6 abuts against the rear end of the sliding member 10, the collet body 18 is opened, and the subsequent core B is released (see FIG. 5). Here, when the forward movement of the chuck body 18 is canceled, the chuck body 18 is retracted by the elastic member S, and the front outer peripheral surface of the chuck body 18 and the inner surface crotch portion 15 of the sliding member 10 are again. By contact, the frictional force is rubbed, and the sliding member 10 is also retracted. As the sliding member 10 is retracted, the paper size clamped on the refill mentioned above applies Chinese National Standard (CNS) A4 (210X297 mm) -16-'~ " " (Please read the note on the back first Please fill in this page for the matters) Order printed by the employee's consumer cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs Printed by the employee's consumer cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs Printed by 580458 A7 _B7_ V. Description of the invention (14) The core A of the returned component 1 1 is also back, This residual core A also retracts the subsequent core B. released from the aforementioned chuck body 18. Then, the chuck body 18 is closed with the chuck collar 6, and the subsequent core is clamped and retracted, but the residual core also retracts from the sliding member 10, so that no gap is generated between the subsequent core B and the residual core A. In the second example or the first example described above, the collet body is not holding the refill. Since the outer diameter of the outer peripheral surface of the front end of the collet body is smaller than the inner diameter of the inner surface of the sliding member, The chuck body is easily assembled to the sliding member. In addition, when assembling by an automatic assembly machine or the like, the front portion of the chuck body can be made to have almost the same outer diameter, so that a parts dispenser can also be applied. A third example will be described with reference to FIG. 6. In this example, an outer crotch portion 20 is formed on the outer peripheral surface of the rear end of the sliding member 19, and an inner crotch portion is formed by sandwiching the cylindrical portion 22 at the front end of the chuck body 21. Department 2 3. In addition, the chuck body can be easily assembled by positioning the chuck body outside the sliding member. That is, in the aforementioned first or second example, the width of the chuck body can be reduced by using the width of the slit formed in the chuck body, but in this example, the chuck body is opened outward to assemble it. Therefore, there are no restrictions as mentioned above. In addition, in this example, since the slide member is sufficiently retracted into the cylindrical portion, it is possible to store the refill protective tube in the pen head member after use. A fourth example will be described with reference to Figs. This example has almost the same structure as the first example, but the refill check member is different.

Description of the invention (15) (Please read the precautions on the back and fill in this page) However, the refill check member 2 4 can be inserted into the tubular refill protection tube 1 2; It can be formed by attaching metal ions and the like on the surface of the refill check member 24, that is, the so-called electroforming process is used to form the refill protection tube 12 around the refill check member 24. In addition, by disposing the refill check member 24 in the refill protection tube 12, even if the residual core A is shortened, the residual core can be held, and therefore the core can be effectively used. However, in this fourth example, the method of using the residual core A extremely effectively is to press the refill protection tube into the pen head member; in addition, the refill protection tube 25 is integrally formed on the pen head member 9 (refer to FIG. 9: (Example 5) Yes. In any case, since the distance from the refill non-return member 26 to the tip of the refill protection tube 12 is shortened, the shortened residual core A is further clamped, so that the residual core can be used extremely efficiently. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs Refer to Figures 10 and 11 to illustrate the sixth example. In this example, the refill non-return member or the refill protective tube shown in the aforementioned first example is integrally formed with the sliding member. To explain in more detail, a refill check piece 29 composed of a plurality of divided pieces is formed in the middle portion of the inner surface of the sliding member 28, and an actual holding pen is formed on the inner surface of the refill check piece 29. The core-shaped ladder-shaped protrusion 3 0. In addition, two opposing engaging pieces 31 extending rearward are formed at the rear of the sliding member 28, and an inner surface crotch portion 32 is formed on the inner surface of the rear end of the engaging piece 31. This inner surface cymbal 32 is in contact with and interlocks with the outer cymbal 13 of the chuck body 5. A refill protection tube 3 3 is also integrally formed at the front portion of the sliding member 28, and a front portion of the refill protection tube 3 3 is formed to face forward. This paper is applicable to the national paper standard (CNS) A4 specification ( 210X297 mm) -18-580458 A7 B7 V. Description of the invention (16) Conical part with reduced bore diameter 34. When writing, you can clearly see the tip of the refill, and you can write correctly. (Please read the precautions on the back before filling out this page.) However, as in this example, the refill non-return member or refill protection tube is integrally formed on the sliding member. Therefore, the cost of manufacturing the assembly and the cost of assembly Can be slightly reduced; the result: can provide consumers with low-cost finished products. In addition, since the rear portion of the sliding member is an engaging piece divided into two, the combination of the chuck body and the sliding member becomes easy. A seventh example will be described with reference to FIG. 12. The seventh example is a modification of the aforementioned sixth example. A slit 37 is formed in the core protection tube 36 of the sliding member 35, and a protrusion 38 for holding the core is formed on the inner surface of the core protection tube 36. That is, by forming the refill non-return portion (the protrusion 3 8) on the refill protection tube 36, the refill can be clamped even if the remnant becomes shorter, so the remnant can be effectively used. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs Refer to Figures 13 and 14 for the eighth example. The eighth example is an example in which the cylindrical portion of the sliding member in the aforementioned first example is constituted by a member different from the sliding member, and can slide while applying frictional resistance. A detailed description is that a sealing ring 40 formed of a rubber-like elastic body is fitted on the outer surface of the rear of the sliding member 39, and the cylindrical member 41 is externally fitted in a state of contacting the sealing ring 40. To the rear of the aforementioned sliding member 39. However, in this example, the o-ring 40 is composed of a sliding member and another member, but it may be integrally formed by forming peripheral ribs or the like on the outer peripheral surface of the sliding member. In addition, an inner surface crocodile portion 4 2 is formed on the inner peripheral surface of the rear end of the cylindrical member 41 in contact with the outer crocodile portion 13 of the chuck body 5. The action is almost the same as the first example above, but when the refill is contained, the refill protection tube is made to arrive at -19- This paper size is applicable. National Standard (CNS) A4 size (210X297 mm) 580458 A7 _B7_ V. Description of the invention (17) (Please read the precautions on the back before filling in this page) By connecting to the note side, etc., the refill protective tube 12 can be completely contained in the nib member 9. The sliding member 39, which fixes the refill protective tube 12, is blocked by the frictional resistance of the sealing ring, and slides the member toward the rear into the cylindrical member 41. Figure 4 3 is a standard collar for preventing the cylindrical member of the sliding member 39 from being disengaged. However, it is not always necessary when the frictional resistance of the seal ring is sufficient. Then, when a standard collar is not attached, the combination and disassembly of the sliding member and the cylindrical member are easy, and the repair operation is also easy when the core is stuck. A ninth example will be described with reference to FIG. 15. The ninth example is that in the first example described above, the outer surface of the chuck body 13 of the chuck body 5 and the inner surface of the slide member 10 are formed with screw portions 44 and nut portions 45 on the surfaces thereof. When the chuck body 5 and the sliding member 10 are assembled, the chuck body 5 is strongly closed and assembled to the sliding member 10; when disassembled, the chuck body 5 and the sliding member 10 are rotated relatively, the chuck body 5 The screwing of the screw 4 4 and the nut 4 5 of the sliding member 10 is completed, and the two (5, 10) are separated from each other, so that they can be easily disengaged. Printed by the Consumer Goods Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs in consideration of the ease of assembling and disassembling the chuck body and the sliding member, and taking into consideration the use of such as Figure 16 (No. 10) or Figure 17 (No. 1 1 example) The structure shown. The example shown in FIG. 16 is an example in which the slits 48 are formed in the cylindrical portion 47 of the sliding member 46. By using this fine slit 48, the tubular portion 47 can be easily opened and closed, and the chuck body and the sliding member can be easily assembled and disassembled. The ninth example is almost the same as the sixth example shown in FIG. 11. Drawing number 4 9 is the inner crotch part which is in contact with the outer crotch part of the chuck body. -20- This paper size is in accordance with Chinese National Standard (CNS) A4 specification (21〇 × 297 mm) 580458 A7 ——___ _B7 V. Description of the invention (18) In addition, the example shown in Figure 17 is for The aforementioned fine slits 48 are formed large, so that the aforementioned cylindrical portion becomes a rod-like portion 50, and a recessed portion 5 1 is formed in the middle portion of the sliding member 46, and the inner surface of the pen tip member is formed into the recessed portion 5 An example of a long groove that engages. When the pen head member is separated from the shaft body, the sliding member is also stretched until the chuck body comes out of the pen head member, and cannot be completely pulled out because the sliding member is engaged with the pen head member; as a result: The rod-like portion 50 is opened by the opening action, and the sliding member is separated from the chuck body. Even if the core is crushed in the sliding member, it is easy to repair. The 12th example will be described with reference to Figs. The same configuration as the first example described above will be omitted. A sealing ring 5 2 formed by pressing a rubber-like elastic body or the like in sliding contact with the inner surface of the nib member 9 is pressed onto the outer peripheral surface of the sliding member 10, but a circumferential protrusion and the like are integrated to form the sliding member. Yes. Then, the sliding resistance force against the pen tip member 9 of the sliding member 10 is set to be greater than the sliding resistance force against the aforementioned lead refill check member 11 of the lead. It is the same as described later, but if the residual core A is pushed out with the subsequent core B, the sliding member 10 is also pushed out, but the sliding resistance force with the pen tip member 9 is increased; as a result, the sliding member 10 is maintained in a static state, and the residual core is pushed out. A. Here, the aforementioned chuck body 5 is composed of a chuck piece of 2 divisions, 3 divisions, or 4 divisions, which is a so-called collet chuck; when the pen body is firmly closed without holding the refill, the chuck body The outer crotch portion 13 of 5 is detached from the inner crotch portion 15 of the sliding member 10. That is, the chuck body 5 and the sliding member 10 can be separated and combined. I.

Description of the invention (19) (read the precautions on the back before filling in this page) and then 'contact the middle section 16 of the sliding member 1 0 in front of the inner surface of the pen tip member 9 and form the sliding member in the standard The inner surface section 17 within the advance amount of 10. Next, the operation will be described. The state in FIGS. 18 to 20 is a state where the residual core A deviating from the chuck body is clamped by the refill non-return member 11, and the subsequent core b is clamped by the chuck body 5. When the refill groove 2 is pushed to the front in this state, the chuck body 5 and the chuck collar 6 are advanced into the cylindrical portion 14 without contact, and the subsequent core b held by this Go forward too. As the follow-up core B advances and pushes the residual core, the residual core a also advances, but because it is clamped by the refill non-return member 1 1, the slide member i 0 also advances. However, since the sliding resistance force of the pen tip member 9 to the sliding member 10 is set to be larger than the sliding resistance force of the refill non-return member 11 to the refill, the sliding member 10 maintains a stationary state while moving forward. The core protrudes from the tip of the slide member 10 (the tip of the refill protection tube 12). However, when the aforementioned sliding resistance force is reversed, the sliding member 10 advances most advanced ′ and then the refill delay protrudes from the tip of the sliding member 10, resulting in an uncomfortable feeling. Printed by the staff of the Intellectual Property Bureau of the Ministry of Economic Affairs on the cooperative. Then, the chuck body 5 or the chuck collar 6 advances further, and the immediate end of the chuck collar 6 abuts against the rear end face of the sliding member 10. While preventing the forward movement of the collet collar 6 (refer to FIG. 21). However, since the chuck body 5 is further advanced, the chuck body 5 is released from the chuck collar 6 at this time, and the clamping of the subsequent core B and the chuck body 5 is released at this time. Here, the chuck body 5 is more advanced. Forward, its front end abuts on the sliding member-22- This paper size is applicable. National Standard (CNS) A4 specification (210X 297 mm) 580458 A7 B7 V. Description of the invention (20) (Please read the precautions on the back before filling this page) 1 0 inner section 1 Oa, then clip The head body 5 advances the sliding member 10. At this time, the residual core A is slightly clamped by the refill non-return member 1 1 ′, and thus advances with the advancement of the sliding member 10, but the subsequent core B is released from the chuck body 5 and therefore has its own weight. Fall down and keep in contact with the residual core A and move forward at the same time (see Figure 22). Next, the middle section 16 of the sliding member 10 abuts on the inner surface section 17 of the front member 9, and the forward movement of the sliding member 10 is regulated (see FIG. 23). As a result of these actions, the refill (subsequent core B and residual core A) and the refill protection tube 12 fixed to the sliding member 10 are moved forward from the nib member 9, and thus protrude from the tip of the nib member 9. More than the initial state. It is printed here by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, and the forward movement of the refill groove 2 is released, and the chuck body 5 is in a state of releasing the subsequent core B, and the outer crotch 13 is moved back to In the cylindrical portion 14, however, if the contact resistance between the slider 10 and the pen member 9 is increased to be larger than the contact resistance between the chuck body 5 and the slider member 10, it may be moved in the contact state. . That is, the chuck body 5 may be moved backward when the slide member 10 is stationary. During the retreating process, the outer crotch portion 13 of the chuck body 5 abuts the inner crotch portion 15 of the sliding member 10, and the sliding member 10 is retracted, but it is delayed by a little more than the sliding member is retracted. The collet collar 6 is closed, and the subsequent core B is clamped again (refer to FIG. 24). Then, after these actions, the residual core A is slightly clamped on the refill non-return member 1 1 of the sliding member 10, so the protruding state of the residual core A is maintained while retreating with the sliding member 10; in addition, the subsequent core B is clamped • 23- This paper size is in accordance with Chinese National Standard (CNS) A4 (210 X 297 mm) 580458 A7 B7 V. Description of the invention (21) Hold on the chuck body 5, so retreat with the back movement of the chuck body 5 . (Please read the precautions on the back before filling in this page) However, after the foregoing actions, the subsequent cores B and residual cores A are retracted, but they are backward with respect to the pen head member 9 from the sliding member 10, but relative to the pen The core protection tube 1 2 (sliding member 10) is not retracted, so that the length protruding from the refill protection tube 12 is not reduced (see FIG. 25). In addition, the sliding member 1 〇 is closed with 〇 5 2 In the state of being pressed into the inner surface of the pen tip member 9, the sliding position is continued, and the rear position is maintained after the pressing operation is cancelled. Therefore, the self-weight drops and a gap is not formed between the subsequent core B and the residual core A. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs Refer to Figures 26 and 27 for the 13th example. The description of the same configuration as the first example is omitted. An elastic member 53 such as a coil spring is provided between the rear end of the sliding member 10 and the connecting member 8 so as to bias the sliding member 10 forward. Then, before the sliding member 10 is urged forward, the urging member 5 3 applies the force, and the chuck body 5 is opened to slide to the cylindrical portion 1 of the sliding member 10 than the outer crotch portion 13. 4 The sliding contact force on the inside is also large. That is to say, the sliding member 10 has nothing to do with slidingly inserting or inserting into the inner surface 14 of the tube portion of the outer crotch portion 13 and applying force and moving forward at any time. However, it is also possible to use a chuck body whose outer crotch portion is not connected to the inner surface of the cylinder portion of the sliding member, but the chuck body made of resin, in particular, takes into account its elasticity and fatigue, and generally increases the opening amount. ; Thus contacting the inner surface of the barrel of the sliding member. Here, it is also considered to increase the inner diameter of the tube so that the outer crotch of the chuck body does not contact the inner surface of the tube, but the tube must also be enlarged. -24- This paper is applicable in this standard.

Outer part of the invention description (22); as a result, it is not only the pen component but also the size The opening amount also becomes larger, so the refill slightly bends and becomes a short refill, it will deviate from the center of the chuck body 5 (see the center of the chuck body 5 in FIG. Part) to hold the refill B, which may cause obstacles to the movement of the refill. Therefore, in this embodiment, the cylinder of the sliding member is reduced, and the outer crotch of the chuck body is brought into contact with the inner surface of the cylinder, and the opening amount is regulated so that the pen is held in the regular clamping portion. core. Next, the operation will be described. Regarding the forward operation of the chuck body and the sliding member, the operation is the same as that of the first example or the twelfth example, so the description is omitted. When the forward movement of the refill groove 2 is released, the inner surface of the outer crotch portion 13 and the cylindrical portion 14 are also retracted at the same time when the chuck body 5 is opened, but the cylindrical portion 14 is formed Since the sliding member 10 is biased forward by the elastic member 53, the sliding member 10 does not retreat. Next, the outer crotch portion 13 of the chuck body 5 abuts on the inner crotch portion 15 of the sliding member 10, and the backward movement of the sliding member 10 is started from this time (see FIG. 29). Of course, it resists the elastic force of the elastic member 53. The chuck body 5 is closed by the chuck collar 6 and clamps the subsequent core B again. At this time, in the state where the subsequent core B is held, the chuck body 5 is slightly retracted in the same manner as in the prior art, but the sliding member 10 is also retracted, so that no gap is formed between the subsequent core B and the residual core A. However, after the foregoing actions, the subsequent core B or the residual core A is retracted, but because it is backward with respect to the pen head member 9 from the sliding member 10, it is not relative to the pen core protection tube 12 (sliding member 1 〇).

In addition, the sliding member 1 〇 is engaged with the outer crotch portion 13 of the chuck body 5, so the retracted position is maintained continuously after the pressing operation is canceled, so it is not caused by the foregoing The elastic member 53 is dropped by the applied force or its own weight, causing a gap to be formed between the subsequent core B and the residual core A. However, in the foregoing example, the elastic member and the sliding member are assembled and assembled by separate members, but as shown in FIGS. 30 and 32, the elastically deformable portion is integrally formed behind the sliding member by injection molding or the like Yes. Specifically, in this example, the elastically deformable portion is formed with a cylindrical portion 55 in front of the sliding member 54, and a freely stretchable mesh elastic deformation portion 56 is formed in the rear portion of the cylindrical portion 55. Fig. 31 is an example in which the above-mentioned sliding member 54 is formed of a resin material by means of injection molding or the like, and the chuck body 57 is also formed of a resin material. As described above, in the opened state, the resin chuck body 5 7 has its outer peripheral surface abutting against the inner peripheral surface of the cylindrical portion 55 of the sliding member 54 and regulates its opening amount. The opening amount is smaller than the diameter of the refill. Of course, it is to hold the refill in a regular position. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economy The sliding member may be biased forward. The 14th example will be described with reference to Figs. 3 3 to 36. A refill groove 59 is disposed inside the shaft body 58 so as to be able to move back and forth, and a chuck body 60 that can be opened and closed is fixed to a front end of the refill groove 59. A chuck collar 6 1 is provided around the front portion of the chuck body 60 to perform switching of the chuck body 60.

Invention Description (25) 6 0's sliding member 6 7. An elastic member 74 such as a coil spring is provided between the rear end of the sliding member 67 and the shaft body 58, and the sliding member 67 is applied forward, and then the sliding member 67 is biased forward. The elastic force of the elastic member 74 is to open the chuck body 60, and the sliding contact force when the edge portion 7 5 other than the protruding portion 70 is in sliding contact with the inner surface of the cylindrical portion 7 1 of the sliding member 6 7 is reduced. Big. That is, the sliding member 6 7 has no sliding contact or non-sliding contact with the inner surface of the cylindrical portion 7 1 of the rim portion 7 5 of the chuck body 60 and applies force to move forward at any time. Here, the chuck body 60 is a so-called collet chuck composed of a chuck piece of two or four divisions. In addition, the middle section portion 7 6 of the sliding member 67 is abutted forward of the inner surface of the pen member 65, and an inner surface portion 7 7 is formed to regulate the advancement amount of the sliding member 67. Next, a method of assembling the chuck body 60 and the sliding member 67 will be described. In a state where the refill is not clamped (the state shown in FIG. 37), the projection of the chuck body 60 is pushed to the rear end of the sliding member 6 7 (the cylindrical portion 7 1) and pushed in , The head of the chuck body 60 is reduced in diameter via the inclined surface 73 (see FIG. 38), and then the protrusion 70 reaches the engaging hole 7 2 at this time, and the protrusion of the chuck body 60 is released.部 70, and open the head of the collet body. Here, the projection 70 of the chuck body 60 is inserted into the engaging hole 72, and at the same time is formed in a state where it is difficult to separate (formed in the state shown in Fig. 33). Next, the foregoing refill check member 68 will be described in detail. Here the refill check 68. A refill socket 6 8 a including a refill that cannot be inserted into two refills is formed in the entire length, and the refill socket has a larger diameter than the diameter of the refill used. Then (Please read the notes on the back before filling out this page) This paper size is applicable. National Standard (CNS) A4 specification (210X297 mm) -28- 580458 A7 _____ _B7_ V. Description of the invention (26) (Please read the precautions on the back before filling this page) The front of the refill socket 6 8 a A refill check portion 6 8 b having a smaller diameter than the diameter of the refill used is formed in the portion. The refill non-return portion 68a is a portion for holding the refill slightly to prevent the refill from retreating. However, since the refill is held in the refill non-return portion 6 8 b, the refill is held by the ridge line, so that the refill can be prevented from rotating when writing is caused by the residual core. In addition, the refill insertion hole 6 8 a is formed in a groove portion 6 8 c having a width smaller than the diameter of the refill used in the axial direction, and the groove portion 68 c includes the entire length of the refill check member 68. To form. Further, the groove portion 6 8 c is formed in the vicinity of the refill check portion 6 8 b up to the outer peripheral edge portion of the refill check member 68. That is, the groove portion 6 8 c near the refill non-return portion 68 b has a slit-like shape passing therethrough. Elastic action is applied to the refill non-return portion 6 8 b holding the refill, which absorbs the unevenness of the refill's caliber%. This groove portion 6 8 c is formed in two opposite places, but it is formed radially. Three or four premises are acceptable; in addition, grooves with triangular cross section are also available. However, a conical portion 68d is formed above the refill insertion hole 68a. It is easy to introduce the refill into the refill insertion hole 68a. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs In addition, the 'refill check member 68 mentioned above is formed of a resin material. Then, the position of the gate (the hole where the resin enters the cavity) during injection molding is in a direction that is straight with respect to the axis of the refill insertion hole 6 8 a and the position where the groove portion 6 8 c is formed (see section 3 5 B, 3 5 C). By inserting the resin from the direction of strength of the plastic hole plug, the bending and damage of the plastic hole plug caused by the inflow pressure of the resin is prevented. In addition, the groove portion 68c also has a function of maintaining uneven fixing strength when the refill check member 68 is press-fitted and fixed to the sliding member 67. That is, the Chinese standard (CNS) A4 specification (210 × 297 mm) is applied using the mound paper standard. -29-580458 A7 B7 V. Description of the invention (27) (Please read the precautions on the back before filling this page) Because The groove 6 8 c causes elastic deformation of the refill check member 68. However, in this example, the refill insertion hole 6 8 a and the refill check portion 6 8 b are integrally formed, but a refill check portion is formed by another member so that it is located in a member having the refill insertion hole as in this example. (For example, the example shown in Fig. 53) ° Secondly, the operation will be described, and the state in Figs. 3, 3, and 4 is that the residual core A of the chuck body 60 is clamped in the refill and returned. The member 68 and the subsequent core b are clamped in the state of the chuck body 60. In addition, the sliding member 67 is urged forward by the elastic member 74, but the rear end portion of the engagement hole 72 of the cylindrical portion 71 abuts against the protrusion engaged with the chuck body 60, so that The forward movement of the sliding member 67 is regulated. When the refill groove 5 9 is pushed to the front in this state, the chuck body and the chuck collar 6 1 are advanced into the cylindrical portion 7 1 in a non-contact state, but they are moved by the elastic member 7 4 Since the sliding member 67 is moved forward, the sliding member 67 also maintains the engagement state of the engagement hole 72 and the protrusion 71 at the same time. Therefore, the subsequent core B held by the chuck body 60 or the residual core A held by the refill check member 68 is moved forward with the sliding member 67. Printed by the Employees' Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. Then, the middle section portion 7 6 of the sliding member 67 is abutted against the inner surface portion 7 7 of the pen member 65, preventing its forward movement (refer to FIG. 39). However, the protrusion 70 of the aforementioned chuck body 60 is inserted into the engaging hole 72, so the chuck body 60 or the chuck collar 61 and the subsequent core B or the residual core A are all moved forward, but the clamp The headgear ring 6 1 prevents the slide member 6 7 from moving when it comes into contact with the rear end portion of the cylindrical portion 7 1 of the slide member 6 7. Then at this time, the chuck body 60 is opened, and the subsequent core B is released, and the chuck body 60 -30- This paper size applies to the Chinese National Standard (CNS) A4 specification (210X297 mm) 580458 A7 B7 V. Invention Note that the edge portion 7 5 of (28) is in contact with the inner surface of the cylindrical portion 7 1 of the sliding member 67 (see FIG. 40). Here, when the forward movement of the refill groove 59 is released, the edge portion 7 5 is rubbed against the inner surface of the cylindrical portion 71 while the collet body 60 is opened, but it is also retracted, but a tube is formed. Since the sliding member 6 7 of the shape portion 71 is elastically moved forward by the elastic member 7 4, the sliding member 6 7 does not retreat. Then, the projection 70 of the chuck body 60 abuts against the rear end of the engaging hole 7 2 of the sliding member 67, and the backward movement of the sliding member 67 is started (see FIG. 41). Of course, it resists the elastic force of the elastic member 74. Then, the chuck body 60 is closed with the chuck collar 61, and the core B is clamped again (refer to FIG. 42). At this time, in the state where the subsequent core B is clamped, the chuck body 60 is slightly retracted in the same manner as in the prior art, but the sliding member 67 is also retracted, so that no formation is formed between the subsequent core B and the residual core A. gap. However, after the foregoing action, the subsequent core B or the residual core A is retracted, but since it is retracted with respect to the pen head member 65 from the sliding member 6 7, it is relative to the pen core protection tube 6 9 (sliding member 6 7). It is not retracted, so that the length protruding from the refill protection tube 69 is not reduced. In addition, the sliding member 67 is engaged with the protrusion 70 of the chuck body 60 similarly to the above-mentioned examples. Therefore, the retracted position is maintained continuously after the pressing operation is canceled, so that it does not fall due to its own weight. As a result, a gap is formed between the subsequent core B and the residual core A. However, in the previous example, the elastic member and the sliding member are assembled and assembled with separate members, but as shown in Figure 4 and 3, the elastically deformable part (please read the precautions on the back before filling in this page). The paper size printed by the Ministry of Intellectual Property Bureau ’s Consumer Cooperatives applies the Chinese national standard (CNS) A4 specification (210X297 mm) -31-580458 Printed by the Intellectual Property Bureau ’s Consumer Cooperatives of the Ministry of Economic Affairs A7 _B7_ V. Invention Description (29) The bits may be formed integrally behind the sliding member by injection. Specifically, the elastically deformable portion in this example is formed with an elastically deformable portion 79 that can be expanded and contracted in a mesh shape at the rear of the sliding member 78. A modification will be described with reference to FIGS. In this example, an engaging hole 82 is formed in the cylindrical portion 81 of the sliding member 80 and a narrow slit 83 is formed which is narrower than the protruding portion 70 of the chuck body 60. In addition, an inclined surface 8 4 is formed on the rear end surface of the cylindrical portion 81, and the inclined surface makes the projection 70 easily fit to the engaging hole 82. The projection 70 of the chuck body 60 is pushed to the inclined surface 84, and the cylindrical portion 81 is elastically deformed with the slit 83 as a center (see FIG. 45). The projection 70 is easily introduced into Inside the engaging hole 82. In addition, at a position facing the inclined surface 84, an inner surface inclined surface 85 is formed on the inner surface of the engaging hole 82. With this inner surface inclined surface 85, the chuck body 60 and the sliding member 80 can be separated. That is, if the refill is broken in the sliding member, it can be easily repaired. A modification of the engaging hole will be described with reference to FIGS. The cylindrical portion 8 7 of the sliding member 8 6 is formed with the same engaging hole 8 8 as described above, but is connected to the engaging hole 8 8 to form an L-shaped guide groove 89. Then, the end of the guide groove 89 is formed up to the end of the cylindrical portion 87. That is, when the chuck body is assembled to the sliding member in this example, the chuck body and the sliding member are rotated while they are relatively rotated and assembled (see Figs. 4 to 7). With this configuration, it is easier to assemble; even if the refill is broken in the sliding member, the chuck body and the sliding member are easily disassembled and repaired easily. However, in this embodiment, the paper size protruding from the collet collar of the collet body is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) _ 32-(Please read the precautions on the back before filling this page ) 580458 A7 B7 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs. 5. Description of the invention (30) The output is small, and there is also a distance to close the elastic member. The slide member is rotated and assembled in a state, but for example, if the chuck body is lengthened, the slide member can be assembled without advancing the chuck body. In the above example, since the engaging portion is formed as a through hole, it is easy to process. In particular, when the sliding member is formed by injection molding, a mold can be manufactured at a low price; and the dimensional accuracy can be ensured. In this example, a fan-shaped raised portion 90 is formed on the front end surface of the chuck body along the shape of the chuck body 60 (see FIGS. 48 and 49). Then, the fan-shaped bulge portion 90 is formed as a push-out portion when the chuck body 60 is pressed into the refill groove 59. The specific press-in method will be described later in detail. However, in this embodiment, the raised portion is a fan-shaped protrusion, but as shown in FIG. 50, the central portion on the circumference of the front end surface of the chuck body 60 may be raised into a mountain shape; As shown in FIG. 51, the front end surface of the chuck body 60 may be formed by extending from the projection 70 to the front and extending in the longitudinal direction. Next, a method of assembling the chuck body 60 and the lead groove 59 will be described with reference to Fig. 52. Initially, the refill groove 59 is erected and the elastic member S is inserted into the aforementioned refill groove 59 from above (front). Then, the shaft body 5 8 is inserted from below the refill groove 5 9. Next, a collet collar 6 1 is placed under the shaft body 58 and the collet body 60 of this embodiment is inserted. Next, the pressing member 91 is brought into abutment with the raised portion 90 of the chuck body 60. The force is applied to the pressing member 91. Of course it is the downward force. Therefore, the chuck body 60 receives the force from the aforementioned pressing member 91 through the bulging portion 90. With this force, the lower part of the chuck body 60 is pressed into the refill groove 59. At this time, from (Please read the precautions on the back before filling this page) This paper size applies the Chinese National Standard (CNS) A4 specification (210X29 * 7 mm) -33- 580458 A7 B7 Employee Consumer Cooperatives, Intellectual Property Bureau, Ministry of Economic Affairs Printing 5. Description of the invention (31) The pressing member 91 described above exerts excessive force on the chuck body 60, and the raised portion 90 formed at the front end of the chuck body 60 is deformed outward or inward. This prevents deformation of the front part of the chuck body. That is, the front part of the chuck body which is internally connected to the chuck ferrule 61 does not bulge, so that it can be assembled while maintaining the correct shape. In addition, in the foregoing embodiment, a protrusion 70 is formed on the front outer peripheral portion of the chuck body 60, the protrusion 70 is engaged with the sliding member 67, and the sliding member 67 is retracted and the residual core is eliminated. Clearance of subsequent cores. That is, the shape of the protrusion 70 is a very important constituent element. Therefore, deforming the protrusion 70 causes unevenness in the retracted position of the sliding member 67, etc. As a result, unevenness of the pen core extending means (the extending length of the sliding member) is also caused. Slight unevenness may damage the protrusion 70, and the slide member 67 cannot be moved backward. In order to prevent this, it is preferable to form a raised portion. The fifteenth example will be described with reference to Figs. 53 and 54. The same components as in the aforementioned 14th example have the same drawing numbers. A refill groove 59 is disposed inside the shaft body 58 so as to be able to move back and forth, and a chuck body 60 capable of opening and closing is fixed to a front end of the refill groove 59. A chuck ferrule 61 for surrounding the chuck body 60 is used to surround the chuck body 60. In addition, an elastic member S such as a coil spring which urges these members to the rear is opened and provided between the aforementioned core groove 5 9 and the inner surface end portion 9 3 of the shaft body 58. Then, the refill extending means of the invention is constituted by the refill groove 59 or the chuck body 60, the chuck collar 61, and the spring member S. In addition, on the front part of the aforementioned shaft body 5 8 using a hand such as a twist lock (please read the precautions on the back before filling out this page) This paper size is applicable. National Standard (CNS) A4 specification (210X29 * 7 mm) -34- 580458 Α7 __ Β7 V. Description of the invention (33) The amount of protrusion of the pen core increases, and then adjusting the protrusion of the pen core becomes complicated and troublesome. (Please (Read the precautions on the back before filling in this page.) In addition, a gap X is formed near the cylindrical portion 7 1 of the sliding member 6 7 and the shaft body 5 8, but the gap is set to be higher than the chuck body 6. The fitting distance Y with the sliding member 67 is also short. That is, when the protrusion of the chuck body 60 is inserted into the engaging hole 7 2 (assembly) of the sliding member 6 7, the cylindrical portion 7 1 near the engaging hole 7 2 is opened, but the pen head member 6 5 is combined to After the shaft cylinder 1, the opening of the cylindrical portion 71 is regulated, and the insertion state of the protruding portion 70 and the engaging hole 72 is maintained. That is, the projection 70 does not come out of the engaging hole 72. Further, the sliding member of this example is formed as a sliding member having a slit 8 3 as shown in the aforementioned modification of the 14th example; the width of the slit is formed when the sliding member is attached to the pen tip member, for example, even if the The width of the slit is widened so that the protrusion of the chuck body does not come off. That is, the difference between the width of the protruding portion of the chuck body and the width of the slit is larger than the difference between the inner diameter of the pen member and the outer diameter of the cylindrical portion of the sliding member. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, the drawing number 9 8 is a rubber seal formed between the inner rib 65a of the pen tip member 65 and the sliding member 67. ◦ Sealing ring 9 8 applies sliding resistance. The sliding resistance force of the pen tip member 65 of the sliding member 67 is set to be larger than the sliding resistance force of the foregoing lead back check member 96 of the pen lead. That is, even if the pen core and the chuck body 60 are advanced together, the sliding member 67 is moved in the pen head 65 to be regulated. However, the refill holding force of the aforementioned refill non-return member is 20 gf ~ 100 g, which is the most suitable value. If it is smaller than this value, the core will slip off. On the contrary, if it is higher than this value, it will not be able to extend the core. However, In this example, 0 seal ring 9 8 is slid into shape -36- This paper size is applicable. National Standard (CNS) A4 specification (210 × 297 mm) 580458 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 B7 V. Description of the invention (34) The rib 6 5 a is formed on the inner surface of the pen head member 6 5 but not slip It can be connected to the inner rib, and it can be slid on the inner surface of the tube. However, considering the deformation of the O-ring and the compression of air caused by sliding, it is ideal to form the rib. In addition, a base portion 6 2 a formed with a pen holder 62 is press-fitted and fixed to a rear portion of the shaft body 1, and an eraser 63 is attached to the rear portion of the refill groove 59 to attach and detach. Reference numeral 6 4 is a cover for covering the eraser 63, and is detachably mounted on the rear part of the foregoing lead core slot 59. In addition, a grip member 66 made of a rubber material is attached to the front of the shaft cylinder 58. This gripping member is mounted across the recessed portion 5 8 a formed in the barrel 1 and the recessed portion 6 5 b formed in the nib member 6 5 to prevent the nib member 6 5 from being loosened from the barrel 1 and can reach the nib member 6 5 Hold your fingers up to the front. This structure is the same as the foregoing fourteenth example. Next, the operation will be described. The state in FIG. 53 is a state where the residual core A deviating from the chuck body 60 is clamped by the refill check member 96, and the subsequent core B is clamped by the chuck body 60. In addition, the sliding member 67 is moved backward by the protrusion 70 of the chuck body 60. In this state, the refill groove 5 9 is pushed to the front, and the collet collar 6 1 and the collet body 60-together with the subsequent core B held by the collet body 60 and the residues pushed to the subsequent core B Core A advances simultaneously. At this time, since the residual core a is slightly clamped on the refill check member 96 of the sliding member 67, the sliding member 67 also advances. However, due to the increased setting, the sliding of the pen tip member 65 of the sliding member 67 is performed. Due to the resistance force, the sliding member 67 does not move, and the residual core A slides into the aforementioned non-return member 96, protruding from the tip of the sliding member 67, and the paper size is suitable for financial affairs (CNS) (210X 297) "37-I (Please read the precautions on the back before filling this page) 580458 A7 __ B7__ V. Description of the invention (35) (Please read the precautions on the back before filling this page). Then the collet collar 6 1 abut It reaches the segment portion 97 of the pen head member 65 and regulates its forward movement. At this time, a gap z is formed between the protruding portion 70 of the chuck body 60 and the front end portion of the engaging hole 72 of the sliding member 67. (Refer to FIG. 55.) Here, when the lead core groove 59 is advanced further, the chuck body 60 slightly advances the subsequent core B (and the residual core a), while abutting the projection 70 of the chuck body 60. To the front end of the engaging hole 72 (refer to Figure 56). At this time, the chuck body 60 is opened, and the subsequent core b held by it is released. It is also possible to open the collet body at the moment when the collet collar 61 abuts against the segment portion 9 7. When the refill groove 5 9 moves forward, the projection 7 0 of the collet body 60 advances the sliding member 6 7 Move. Then, the middle section portion 7 6 of the sliding member 6 7 abuts the inner surface rib 6 5 a of the pen head member 6 5 a and the rear end portion 7 7 to prevent its forward movement (refer to FIG. 5 7). It is printed here by the Consumer Cooperative of the Bureau, and the forward movement of the refill groove 59 is released, so that the chuck body 60 is retracted, but the sliding member 6 7 does not retreat because of the impedance applied by the 0 seal 9 8 Then, the projection 70 of the chuck body 60 abuts against the rear end portion of the engaging hole 7 2 of the sliding member 67 (see FIG. 58), and the backward movement of the sliding member 67 is started. The body 60 is closed with the collet collar 61, and the subsequent core B is clamped again (refer to FIG. 53). At this time, in the state of holding the subsequent core B, the chuck body 60 is the same as in the conventional technology. Retreating slightly, but since the sliding member 67 is also retracted, a gap is not formed between the subsequent core B and the residual core A. However, as before Follow-up core B or residual core A retreats, but with the sliding paper size, the Chinese National Standard (CNS) A4 specifications (210X: 297 mm) -38-580458 A7 B7 Explanation of the invention (36) The member 6 7 is retracted relative to the pen member 65 and is not retracted relative to the sliding member 67, so the length protruding from the tip of the sliding member 67 is not reduced. The engaging hole 7 2 of the member 67 is engaged with the protrusion 70 of the chuck body 60, so that the retracted position is maintained after the pressing operation is canceled, so that it does not fall due to its own weight, resulting in subsequent cores B and A gap is formed between the residual cores A. In addition, in this embodiment, after the collet collar 61 is brought into contact with the section 9 7, that is, after the collet body 60 is opened, the protrusion 70 of the collet body 60 is brought into contact with the engaging hole 7. 2 front end, so the chuck body 60 does not open in any specification, so you can get a good chuck collar sound. The 16th example will be described with reference to Figs. This example is an example in which the cylindrical portion of the sliding member 67 described above is constituted by another member. A window hole 100 'is also formed in the cylindrical member 99 of this example, and the projection 70 of the chuck body 60 is inserted through the window hole 1000. In addition, the 'tubular member 9 9 is press-fitted and fixed to the main body of the sliding member, and the press-in distance is arbitrarily set during assembly. The operation is the same as the above-mentioned 15th example; therefore, its description is omitted, but in this example, the pressing distance to the sliding member body of the cylindrical member 99 can be changed, so it is pressed to the cylindrical The press-in distance of the sliding member of the part sets the size of the finished product or the protruding length of the refill. As mentioned above, in the above-mentioned 15th or 16th example, the rear end of the sliding member is normally located forward of the segment portion 97 of the pen head member 65, and the rear end of the sliding member and the front of the collet collar A gap is formed, but the rear end of the aforementioned sliding member is located behind the segment of the pen head member, and (please read the precautions on the back before filling this page) This paper size applies the Chinese National Standard (CNS) A4 specification (21 〇X 297 mm) -39- 580458 Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 ___B7_ V. Description of the invention (37) It is also possible to form a gap between the rear end of the sliding member and the front of the collet collar. It is important that in the state where the collet body holds the subsequent core, it is sufficient if there is a gap where the sliding member can retract. Without this clearance, the collet body cannot be retracted with the writing pressure; as a result, the effect of holding the refill wedge is weakened, and the refill is retracted due to the aforementioned writing pressure. Here, an example of a mold device for accurately forming the chuck body is given. The description will be made with reference to FIGS. 60 to 62. Inside the mold 101, a plurality of mold cavities 102 divided into a shape of the aforementioned chuck body 60 and a plastic hole plug 103 forming an inner shape of the chuck body 60 are arranged. The aforementioned divided mold cavities 1 0 2 are formed by forming a back part 60 0 a of the chuck body 60 and a front part 60 c by a mold cavity 1 〇2a, and forming an inclined surface 6 contacting the chuck collar 6 1 0 b's cavity 1 〇2 b. Specifically, a through-hole 102d is formed at a position where the inclined surface 60b of the mold cavity 1 0a is formed, and a through-hole 102d that forms the inclined surface 60b is provided in the through-hole 10b. 6 2 photos). That is, the cavity 1 0 2 b is formed so that at least only the inclined surface 6 0 b forming the chuck body 60 can be replaced. Then, when it is desired to fine-tune the angle of the inclined surface 60 b of the chuck body 60 or the shape of the inclined surface 60 b, it is only necessary to remove the aforementioned mold cavity 1 0 2 b and correct or redo the portion. However, in the foregoing example, the mold cavities forming the rear portion 60 a and the front portion 60 b of the chuck body 60 are integrated, but as shown in Fig. 63, they may be formed separately. Specifically, it is formed by forming a cavity 1 0 2 a of the rear part 60 a of the chuck body 60, and forming a cavity 1 0 2 b of an inclined surface 60 b, and forming a cavity 1 of the front part 60 c. 2 c is also acceptable.

However, the drawing number S is a spring member such as a coil spring that urges the aforementioned first chuck body 106 or refill groove 105 to the rear. Next, the first chuck body 106 and the second chuck body 109 will be described in detail. An outer crotch portion 1 1 3 is formed on the outer periphery of the front end of the first chuck body 106. In addition, a cylindrical portion 1 1 4 is formed to extend behind the second chuck body 109, and an inner surface of the rear end of the cylindrical portion 1 1 4 is formed to an outer surface of the first chuck body 106.部 1 1 3 is in contact with the inner surface of the crotch 1 1 5. In addition, a middle section 1 1 6 is formed on the front outer periphery of the second chuck body 10 9 so as to abut against the inner surface section 117 formed on the inner surface of the pen head member 108. Here, the above-mentioned first chuck body 106 is composed of a chuck piece of 2 divisions, 3 divisions, or 4 divisions, which is a so-called collet chuck; it is closed securely without holding the refill. Then, the structure of the outer crotch 113 of the first chuck body 106 is separated from the inner crotch 1 1 5 of the second chuck body 10 9. That is, the first chuck body 106 and the second chuck body 09 can be separated and assembled. Next, the operation will be described. The state shown in Fig. 65 is a state where the residual core A deviating from the first chuck body 106 is clamped by the second chuck body 109, and the subsequent core B is clamped by the first chuck body 106. In this state, the cartridge lead groove 105 is pushed forward, and the first collet body 106 and the collet collar 107 are moved forward, so that the subsequent core B being held is also advanced.

Invention Description (40) 1 〇9 The refill holding portion 1 1 〇 is clamped, and because the inner chin portion 1 1 5 of the second chuck body 1 10 abuts against the outer surface of the first chuck body 1 006, 2 Chuck body 109 and refill A move forward together. At this time, the second chuck body 109 is also advanced slightly. Then, the second chuck body 109 is opened, but even if the second chuck body 109 is opened, the refill is slightly held in the chuck. As the holding portion 1 1 1 advances, the second chuck body 1 0 9 advances as the residual core 厶 advances. Here, the middle section 1 1 6 of the second chuck body 1 09 abuts the inner surface section 1 1 7 of the pen head member 108, and the forward movement of the second chuck body 10 9 is regulated. Here, the refill groove 105 is further advanced, and the residual core is pushed to the subsequent core B while sliding and the forward movement prevents movement of the refill holding portion 1 1 1 of the second chuck body 1 0 9.

In addition, after the above-mentioned operation, the residual core A is retracted relative to the pen head member 108, but it is retracted from the second chuck body 109, so that the protrusion from the second chuck body 109 is not reduced. length. The eighteenth example will be described with reference to Figs. In this example, the first chuck body 1 1 8 is set to abut the second chuck body 1 1 9 and the inner ridge portion 1 2 0 of the outer peripheral portion of the taper angle 1 2 1 is set to be greater than the second chuck body 1 An example in which the cone angle 1 2 2 of the outer peripheral surface of the apex portion is large. In addition, by making the taper angles of the first chuck body and the second chuck body different, it is possible to absorb variations in the clamping positions of the respective chuck bodies holding the refills. That is, for example, when the first chuck body is formed of resin, elasticity is fatigued due to elapsed time, and the outer diameter of the first chuck body when it is closed is reduced. As a result, the second chuck body is positioned ahead of the second setting The chuck body retracts, so the holding force of the refill is also affected. This problem is solved by changing the taper angle of each chuck body. An example in which the taper angles of the respective chuck bodies are set to be different is that the taper angles of the respective chuck bodies of the eighteenth example described above may be reversed. That is, the cone angle 1 2 1 of the first chuck body 15 may be reduced and the cone angle 1 2 2 of the second chuck body 1 1 9 may be increased. This eighteenth example is particularly effective when the first chuck body is formed of a metal material and the second chuck body is formed of a resin material. In addition, since the second chuck body has a higher grip force than the first chuck body, it also has the effect of preventing the core from sloshing at the tip. Other examples include those shown in Figs. This is the example of this paper.

It is a matter of course that the angles of the cone angle 1 2 8 and the cone angle 12 9 of the second chuck body 1 2 3 are different from each other. Other examples are also given. The example shown in FIG. 70 is an example in which a freely stretchable netting portion 1 3 3 is formed in the middle portion of the cylindrical portion 1 3 2 of the second chuck body 1 3 1, but the netting portion is changed, and It is also possible to form a stretchable rubber-like elastic body 134 using a molding technique such as two-color molding (molding of different materials) (see FIG. 71). Further, as shown in FIG. 73, a thin slit 1 3 6 is formed near the tip of the pen tip member 108, and the tip can be opened so that it can change the closed position of the second chuck body to absorb the lead. The clamping position may be uneven. Printed by the Consumers' Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. Each of the above examples uses the chuck body (the first chuck body) to move the sliding member (the second chuck body) back, but there are other methods. For example, it is a method of forming a wrist portion from the refill groove toward the front, and using the wrist portion to retract the sliding member. Hereinafter, it will be specifically described with reference to Figs. 7 and 75 (the 19th example). A refill groove 1 3 8 is disposed in the shaft body 1 3 7 so as to be able to move back and forth freely, and a chuck body 1 3 9 of an energy switch is fixed to a front end of the refill groove 1 3 8. A chuck collar 1 40 is provided around the front portion of the chuck body 139 for performing the switching of the chuck body 139. In addition, an elastic member 141 such as a coil spring which urges these members to the rear is opened and provided between the aforementioned lead groove 1 38 and the inner surface section 142 of the shaft body 1 37. Then, these refill grooves 1 38 or chuck bodies 1 39, chuck collars 40, and spring members 1 41 constitute the refill extending means of the present invention. The paper standard Lai Jin Guan Jia Standard ((^) "4 specifications (21 (^ 297 mm) Γ45-" ~~ '-580458 A7 B7 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs ) In addition, at the front of the shaft body 1 37, the pen tip member 1 4 8 is freely attached and detached by means of a twist lock or the like; and the pen tip member 1 4 8 is provided with a protrusion protruding from the tip thereof in a freely sliding manner. Slide member 1 4 9. Then, a refill check member 1 50 that holds the refill slightly and prevents the refill from retreating is arranged inside the slide member 1 4 9, but it may be integrally formed with the nib member. Further A groove portion 1 51 is formed in the axial direction on the outside of the above-mentioned two positions of the sliding member 1 4 9. The groove portion 1 51 is not formed until the rear end portion of the sliding member 1 4 9 and is formed only halfway. It is also possible to form the locking portion 1 5 1 a. In addition, the wrist portion 1 5 2 is fixed at an opposite position to the front portion of the refill groove 1 3 8 and an inner protrusion 15 is formed at the front end portion thereof. 3. In this example, the wrist 1 5 2 is composed of components different from the refill groove 1 3 8 'but not integrated It may be formed. Then, the inner protrusion 1 5 3 is freely slidably embedded in the groove portion 1 5 1 of the sliding member 1 4 9. However, the wrist portion 1 5 2 is freely slidably embedded in the shaft body 1.

Next, the operation will be described. The state in FIG. 7 4 is the deviation from the chuck body 1 3 9 Residual core A is clamped in the refill non-return member 150, and the subsequent core B is clamped in the chuck body 1 39. In addition, the sliding member 1 4 9 is biased forward by the elastic member, but from the pen Core slot 1 3 8 Wrist 1 5 2 (Please read the precautions on the back before filling out this page) This paper size applies Chinese National Standard (CNS) A4 (21〇χ 297 公 楚) -46- 580458 Economy Printed by the Consumer Cooperative of the Ministry of Intellectual Property Bureau A7 _____B7__ V. Description of the invention (44) The inner protrusion 1 5 3 abuts against the sliding member 1 4 The groove portion 15 of the 9 'rear portion thus regulates the forward movement of the sliding member 1 4 9. When the refill groove 1 3 8 is pushed to the front in this state, the collet body 139 and the collet collar 1 4 0 are advanced together. However, since the sliding member 1 4 9 is urged by the elastic member 1 5 6, the sliding member 1 4 9 also maintains the engagement state of the inner protrusion 1 5 3 of the aforementioned wrist portion 15 2 and the rear portion of the groove portion 1 51. Go forward at the same time. Therefore, the subsequent core B held in the chuck body 1 39 or the residual core A held in the refill check member 150 is advanced together with the slide member 1 4 9. Next, the middle section 1 5 7 of the sliding member 1 4 9 abuts against the inclined wall 1 5 8 of the pen member 1 4 8 and prevents its forward movement (refer to FIG. 7 6). However, since the inner protrusion 1 5 3 of the aforementioned wrist part 1 5 2 is inserted into the groove part 1 5 1 of the sliding member 1 4 9, the inner protrusion 1 5 3 of the wrist part 15 2 or the chuck body 1 39, The collet collar 1 40 and the subsequent core B or residual core A clamped on the collet body 1 39 can be advanced further (refer to FIG. 7 to FIG. 7). However, when the aforementioned collet collar 140 abuts against the rear end portion of the aforementioned sliding member 149, it prevents its movement. Then, at this time, the chuck body 139 is opened, and the subsequent core B is released (refer to FIG. 78). Here, when the forward movement of the refill groove 1 3 8 is released, the retraction is performed in a state where the chuck body 1 3 9 is opened, but the sliding member 1 4 9 is urged forward by the elastic member 1 5 6. The sliding members 1 4 9 do not retreat. Then, the inner protrusion 1 5 3 of the wrist portion 1 5 2 abuts against the locking portion 1 5 1 a of the groove portion 1 5 1 of the sliding member 1 4 9 described above, and starts the backward movement of the sliding member 1 4 9 (refer to Section 7). Figure 9). Of course it is with elastic members.

Invention Description (45) 1 5 6 . Then, the chuck body 1 39 is closed with the chuck collar 1 40, and the subsequent core B is clamped again (refer to FIG. 74). At this time, in the state in which the subsequent core B is clamped, the chuck body 1 39 is slightly retracted in the same manner as in the prior art, but the sliding member 1 4 9 is also retracted, so that it is not caused between the subsequent core B and the residual core A. A gap is formed between them. However, in this example, the core B or the residual core A is moved backward by the aforementioned action. However, since it moves backward relative to the nib member 1 4 8 together with the sliding member 1 4 9, it does not retreat relative to the sliding member 1 4 9. Therefore, the length protruding from the tip of the sliding member 149 is not reduced. In addition, since the sliding member 1 4 9 is engaged with the inner protrusion 1 5 3 of the wrist 1 5 2, the retracted position is maintained even after the pressing operation is canceled. A gap is formed between B and the residual core. A modification of the nineteenth example will be described with reference to FIG. 80. In the previous example, the wrist was fixed to the refill groove so as to be engaged with the sliding member and interlocked, but in this example, the sliding member was interlocked with the elastic member 1 4 1. Specifically, the wrist portion 1 59 is formed by extending from the rear end portion of the elastic member 1 41 to bend forward. However, the inner protrusion 16 of the front end portion of the wrist portion 159 is engaged with the locking portion 151 of the groove portion 151 of the sliding member 149. Since the wrist is formed by the auto-processing of the spring member, it is easy to assemble and can be manufactured at low cost. The operation is almost the same as the previous example, so its explanation is omitted. Another modification will be described with reference to FIG. 81. This example is on the sliding member (please read the precautions on the back before filling out this page) This paper size applies to Chinese National Standard (CNS) A4 specification (210X297 male sauce) -48-580458 A7 B7 Employees ’Intellectual Property Bureau, Ministry of Economic Affairs Cooperative print 5. Description of the invention (46) A wrist part i 6 2 is extended to the rear of the 6 1 1 so that the wrist part 1 2 can be slidably engaged in the fine slit 1 6 4 of the refill groove 1 6 3, In addition, the operations will be explained next, and the same operations as those in the aforementioned 19th example will be omitted. When the refill groove 1 63 is pushed, the chuck body 139 or the chuck collar 1 40 is advanced, but at this time, the sliding member 1 6 1 is also advanced according to the elastic action of the elastic member 1 5 6. When the forward movement of the sliding member 161 is prevented, only the chuck body 139 and the chuck collar 1 40 are advanced, and then the chuck body 139 is opened. At this time, the fine slits 1 6 4 of the refill grooves 16 3 slide forward with respect to the inner protrusions of the wrist portions 16 2. If the pushing operation of the refill groove 1 63 is released here, the refill groove 1 63 and the chuck body 1 3 9 also begin to retract. At this time, the sliding member 1 6 1 retracts without following the elastic member 1 5 6, and then the inner protrusion 1 6 5 of the rear end portion of the wrist portion 1 6 2 abuts the narrow slit 1 6 4 of the refill groove 1 6 4 According to the abutment, the sliding member 161 also moves backward. The twentieth example will be described with reference to FIG. 82. This example is an example in which the present invention is applied to a side-pressing type mechanical pencil. The rear portion of the shaft body 16 is formed as a refill groove 16 for accommodating a refill, but it may be extended and formed behind the refill extending means described later. In addition, a tapered slide body 1 6 8 is movably disposed forward and backward inside the front body of the shaft body 16 and a chuck body 16 of an energy switch is fixed to a front end of the tapered slide body 1 6 8. A chuck collar 17 for surrounding the chuck body 169 is used to surround the chuck body 169 in front of the chuck body. However, the rear end of the tapered sliding body 1 6 8 will be fixed from the above-mentioned refill groove portion 1 6 7 (please read the precautions on the back before filling this page) This paper size applies the Chinese National Standard (CNS) A4 specification ( 210X297 mm) -49-580458 kl B7 V. Description of the invention (48) (Please read the precautions on the back before filling in this page) Drawing No. 1 8 6 is an opening set on the aforementioned nib member 1 7 6 and sliding member The spring member of the helical spring between 1 7 and 8 urges the sliding member 1 7 to the rear at any time. In addition, the drawing number 1 8 7 is a gripping member made of a rubber material including a front portion of the shaft body 16 and a rear portion of the pen member 1 76. However, a window hole 1 8 of the aforementioned pressing member 183 is formed in the middle of the grasping member 1 8 7 to coincide with the aforementioned shaft body to rotate the front end of the pressing member 1 8 3. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs Next, the actions will be explained. The state shown in Fig. 82 is a state where the residual core A deviating from the chuck body 169 is clamped by the refill check member 179, and the subsequent core B is clamped by the chuck body 169. In addition, the sliding member 17 is biased toward the rear by the elastic member 1 8 6. However, since the rear end (inclined surface 182) abuts on the second abutting portion 1 85 of the pressing member 1 83, it is regulated ( The slide member 1 7 8) moves backward. However, the first abutment portion 1 84 of the pressing member 1 8 3 and the inclined surface 1 8 2 of the tapered sliding body are not in a normal state but in a separated position. However, the isolated state is formed, and even if the diameter of the refill becomes small due to unevenness during production, the clamping force of the collet body is not damaged, and writing can be performed well. However, since the tapered sliding body is in abutting and pressing state at any time, the holding force of the pen core is reduced, so that the pen core may be invaded when writing. When the pressing member 1 8 3 is pressed in the axial direction (radial direction) of the shaft body 1 in the aforementioned state, the second contact portion 1 8 5 of the pressing member 1 8 3 presses the inclined surface 1 7 8 of the sliding member 1 8 2, so the sliding member 1 7 8 advances. At this time, the residual core A due to the refill non-return structure of the sliding member 178 -51-This paper size is applicable. National National Standard (CNS) A4 specification (210X297 mm) Print A7 ___B7_ V. Description of the invention (49) Piece 179, so the residual core A also moves forward with the sliding member 178. When the pressing member 1 8 3 is further pushed, the first abutment portion 1 8 4 of the pressing member 1 8 3 abuts on the inclined surface 1 8 0 of the tapered sliding body 1 6 8 and starts the tapered sliding body. 1 6 8 forward. However, at this time, since the second abutting portion 185 of the pressing member 1 8 3 exceeds the top of the slanted surface 1 8 2 of the sliding member 1 7 8, the sliding member 1 6 8 cannot be moved further upward. It is in a state in which the pressing member 1 8 3 is further pressed to maintain the position (see FIG. 83). Then, the forward movement of the tapered sliding body 168 is started, and with this action, the chuck body 16 of the subsequent core B or the chuck collar 1 70 is advanced. During the advancement process of the chuck body 169, the subsequent core B clamped on the chuck body 169 is abutted against the aforementioned residual core A and pushed at the same time, so the residual core a advances relative to the sliding member 178 (Refer to Figure 8 4). Then, the aforementioned collet collar 170 abuts against the rear end of the aforementioned sliding member 178, the collet body 169 is opened, and the subsequent core is released. However, in this process, the aforementioned sliding member 1 7 8 is biased backward by the elastic member 1 8 6. However, the second abutting portion 1 8 5 of the pressing member 1 8 3 abuts the inclined surface 1 8 2 To the top, so the norm moves backwards. However, the first contact portion 1 8 4 of the pressing member 1 8 3 has a larger forward movement amount of the tapered slider 1 6 8 than the second contact portion 1 8 5 and the forward movement amount of the sliding member 1 7 8 thereof. . That is, the cone-shaped sliding body moves more forward than the sliding member. The specific means is that the length of the inclined surface 180 of the tapered sliding body 168 is longer than the inclined surface of the sliding member 178, so that the forward movement distance is increased.

Invention Explanation (50) Here, when the pressing operation of the pressing member 1 8 3 is released, initially the tapered sliding body 1 6 8 is retracted, so the chuck body 1 6 9 or the collet collar 1 70 is also retracted, and the subsequent core B is clamped again. And complete the back action. However, since the second abutting portion 1 8 of the pressing member 1 8 3 described above is in a state of pressing the inclined surface 182, the sliding member 1 7 8 maintains the advanced position. In addition, at this time, it was also explained in the past technology that the subsequent core B is slightly retracted because it is clamped before the chuck body 169 is completely closed and retracted; as a result, a gap is formed between the residual core A and the (Refer to Figure 8 5). Here, the pressing operation of the pressing member 1 8 3 is further released, and then the second abutting portion 1 8 5 of the pressing member 1 8 3 once again exceeds the top of the inclined surface 1 8 2 with the aforementioned elastic member 1 8 6 The elastic force, the sliding member 1 7 8 also moves backward with the residual core A. At this time, the rear end of the residual core A is in contact with the front end of the subsequent core B (see FIG. 86). However, in this example, after the sliding member is standardized, the movement of the tapered slider is started, and the collet body is opened. However, the movement of the tapered slider is started during the advancement of the sliding member, and the collet collar follows. It can be connected to the rear end of the sliding member, and the collet body can be opened. That is, when the collet body holds the refill, if it is set to the same or greater distance as the amount of returning the refill, and the slide body is closed after the collet body is closed, the forward movement of the slide member is provided. Institutions are also available. The 21st example will be described with reference to Figs. This example is an example in which the sliding member is moved backward by pressing the pen holding member disposed on the shaft cylinder. Details are described below. A grip member 19 made of a rubber elastic body is attached to the front outer peripheral surface of the shaft cylinder 189.
