The conventional elongated object output device has a problem, that is, if the elongated object has a predetermined elasticity and can be elastically deformed, when the elongated object is output, the elongated object will be pushed from the rear by the holding part and be elastically deformed. The side surface of the elongated object contacts the inner peripheral wall of the housing, thereby increasing the sliding resistance when the elongated object is output. In order to reduce the sliding resistance when outputting the elongated object, the inner peripheral wall of the elongated housing is made to be separated from the side surface of the elongated object with a predetermined interval except for the opening at the front end.

On the other hand, when there is a predetermined interval between the inner peripheral wall of the elongated housing and the side surface of the elongated object, if the elongated object is to be used in a state where the elongated object has been pushed out of the housing, the elongated object may face and face inside the housing. Move in a direction orthogonal to the axis direction. In this case, it is difficult to further improve the operability of the elongated object output from the elongated object output device. Therefore, it is desired to have an easy-to-use elongated object output device that can reduce the sliding resistance when outputting the elongated object and reduce the movement of the elongated object in a direction orthogonal to the axis direction during use.

The present invention was conceived to solve the above-mentioned problems, and its purpose is to provide an elongated object output device that is easier to use than the conventional one.

In order to solve the above-mentioned problems, the elongated object output device of one of the embodiments of the present invention includes: a elongated object formed on at least one plane extending in the longitudinal direction with a recessed portion extending substantially through the longitudinal direction; A shaped housing, which can accommodate the elongated object and output the elongated object from an opening formed at one end; and, the holder is configured to be movable in the longitudinal direction within the housing and hold the elongated object; and, At least one plane extending in the longitudinal direction of the elongated object substantially penetrates the longitudinal direction and approaches or contacts the inner peripheral wall of the elongated housing, and the recessed portion of the elongated object substantially penetrates the longitudinal direction without Close to or touch the inner peripheral wall of the elongated shell.

According to the aspect of the present invention, it is possible to provide an elongated object output device which is easier to use than the conventional one.

(Eraser 10)

Fig. 3 is a plan view showing the eraser included in the elongated object output device of the present embodiment, and Fig. 4 is a view showing the eraser of the present embodiment viewed from the direction of the tip portion. As shown in Figs. 3 and 4, the eraser 10 has a substantially quadrangular prism shape, and recesses 12 extending through the longitudinal direction are formed on each surface (upper surface, lower surface, and both side surfaces) extending in the longitudinal direction. The faces are substantially orthogonal to each other. By forming the surfaces and the recesses 12 in this way, the four corners of the cross-section in the direction orthogonal to the longitudinal direction (axial direction) of the eraser 10 will form convex parts (corner posts) having three corners and protruding in the diagonal direction. Protrusion 14). The eraser 10 can be manufactured by, for example, extrusion molding in the longitudinal direction.

As will be described in detail later, the side surface of the corner post protrusion 14 will approach or contact the inner peripheral wall of the housing 20, and the recess 12 will not approach or contact the inner peripheral wall of the housing 20 except for the opening 22 at the front end. Therefore, the sliding resistance when the elongated object 10 is output from the housing 20 can be reduced, and the movement of the elongated object 10 in the direction orthogonal to the axis direction during use can be reduced, and an easy-to-use elongated object output device 1 can be provided. Furthermore, the corner pillar protrusion 14 has a plurality of ridgeline portions extending in the axial direction, and the ridgeline portion can contact the paper surface with a narrower contact range and a higher contact pressure for erasing characters. Therefore, high-quality elimination can be easily performed. and, The ridge portion extending in the axial direction corresponds to the corner in the cross-sectional shape in the direction orthogonal to the axial direction. The corners of the eraser 10 may include natural rounded corners generated during molding, as long as the corners are formed substantially.

(Shell 20)

Fig. 5 is a plan view showing the casing of the elongated object output device of this embodiment, Fig. 6 is a side view showing the casing of this embodiment viewed from the side, and Fig. 7 is a diagram showing the casing of this embodiment as shown in Fig. 5 A cross-sectional view taken along the BB line and viewed from the side direction (the BB arrow direction in FIG. 5). FIG. 8 is a view showing the housing of the present embodiment viewed from the direction of the opening formed in the tip portion.

As shown in FIGS. 5 to 8, the housing 20 is formed into a substantially rectangular tube shape in accordance with the shape of the outer surface of the corner pillar protrusion 14 of the eraser 10. The front end of the housing 20 shown on the left side of FIGS. 5-7 is formed with an opening 22, and the rear end shown on the right side of FIGS. 5-7 is formed with an opening 24, and the eraser 10 can be inserted through these openings. The front side of the housing 20 is formed with non-slip unevenness, and the outer periphery of the rear end is small, and it can be fitted into the cover 40 (refer to FIGS. 1 and 2). For the convenience of the following description, the front end side of the housing 20 where the opening 22 is formed is referred to as the front end in the central axis direction (axial direction) of the elongated object output device 1 of the present embodiment, and the rear end where the opening 24 is formed The side is called the rear.

A guide groove 26 extending in the longitudinal direction is formed on the upper surface of the housing 20, and the guide groove 26 can alternately and continuously form a locking hole 262 with a wider groove width and a non-locking hole 264 with a narrow groove width. For the convenience of the following description, the direction of the groove width (the direction orthogonal to the axial direction in a plan view) is referred to as the width direction. The front end of the guide groove 26 does not reach the opening 22, and the rear end has a reaching opening 24.

As shown in FIG. 8, the inner peripheral wall of the housing 20 that delimits the opening 22 (and the edge 222 thereof) respectively forms a convex portion 28 protruding toward the center axis of the housing 20. The shape of the convex portion 28 is formed corresponding to the shape of the concave portion 12 of the eraser 10, and is close to the concave portion and has a slight gap with the concave portion 12. Eraser 10 in When in use, it deforms in a direction orthogonal to the axial direction. Therefore, the opening 22 of the housing 20 can be exceptionally close to the concave portion 12 to form the convex portion 28. When the eraser 10 is used, although the eraser 10 is elastically deformed in a direction orthogonal to the axial direction, the convex portion 28 abuts the concave portion 12 of the eraser 10 and prevents the eraser 10 from further deforming.

However, in this embodiment, a recess 12 is formed in the center of each surface of the eraser 10 extending in the longitudinal direction. At this time, the area moment of inertia of the eraser 10 can be greatly maintained in response to the bending deformation of the eraser 10 in any direction orthogonal to the axial direction, and the contact area of the eraser 10 to the housing 20 can be reduced. Therefore, it is possible to suppress the bending and deformation of the eraser 10 while reducing the sliding resistance between the eraser 10 and the housing 20 when the eraser 10 is output. The recess 12 of the eraser 10 will not approach or touch the inner peripheral wall of the housing 20. The recess 12 of the eraser 10 is configured to substantially penetrate the longitudinal direction without being close to or touching the inner peripheral wall of the housing 20, thereby reducing the sliding resistance when the eraser 10 is output from the housing 20.

The recessed portion 12 of the eraser 10 and the inner peripheral wall of the housing 20 "substantially penetrate through its longitudinal direction and do not approach or contact" means that, for example, it does not approach or contact within a range that penetrates more than 80% of the longitudinal direction of the eraser 10. It is better not to approach or touch within more than 90% of the length direction of the eraser 10, and it is particularly preferable not to approach or touch within more than 95% of the length of the eraser 10. In the elongated object output device 1 of this embodiment, the recessed portion 12 of the eraser 10 is close to the inner peripheral wall of the housing 20 only at the opening 22. In other parts, the recessed portion 12 of the eraser 10 does not approach or contact the inner peripheral wall of the housing 20.

On the other hand, the outer side surface of the corner post protrusion 14 of the eraser 10 is configured to substantially penetrate the longitudinal direction of the inner peripheral wall of the housing 20 and approach or contact. The inner peripheral surface of the housing 20 formed close to the elastically deformable eraser 10 will abut the eraser 10 when the eraser 10 is elastically deformed. However, the outer surface of the corner post protrusion 14 of the eraser 10 and the inner peripheral wall of the housing 20 "substantially penetrate through the longitudinal direction and approach or contact" means that, for example, they approach or touch within a range that penetrates more than 80% of the longitudinal direction of the eraser 10. Contact with It is better to approach or touch within 90% or more of the length direction of the eraser 10, and it is particularly preferable to approach or touch within 95% or more of the length of the eraser 10. In the elongated object output device 1 of the present embodiment, the outer side surface of the corner pillar protrusion 14 of the eraser 10 penetrates the length direction of the eraser 10 and is close to or in contact with the inner peripheral wall of the housing 20. Therefore, when the eraser 10 is used, the movement (deformation) of the eraser 10 in the direction orthogonal to the axis direction can be reduced.

With this structure, the elongated object output device 1 of this embodiment is easier to use than the conventional elongated object output device, and it is used as the eraser 10 for the elongated object output from the elongated object output device 1 In terms of operability can be further improved.

(Fixer 30)

Fig. 9 is a plan view showing the holder of the elongated object output device of the present embodiment, and Fig. 10 is a side view showing the holder of the present embodiment viewed from the side. As shown in these figures, the holder 30 has a holding portion 31 for holding the eraser 10, an operation portion 32 for the user to operate, an elastic engagement portion 33 that is engaged with the housing 20 to clamp the holder 30, and a connection operation portion The penetration plate 34 of 32 and the elastic engagement portion 33 and the elastic connection portion 35 that connects the holding portion 31 and the elastic engagement portion 33. These constituent elements are integrally formed of a flexible material, such as a resin material.

The holding portion 31 is disposed in the housing 20, and has two clamping plates 312 facing each other, and a connecting plate 314 that connects and supports the rear ends of the pair of clamping plates 312. The two clamping plates 312 are connected to each other. The bottom surfaces of the two opposite recesses 12 of the eraser 10 are separated from each other with a slight interval. The width is narrower than the width of the recess 12, and the thickness (the vertical dimension) is smaller than the groove depth of the recess 12. The clamping plates 312 are respectively submerged in the two recesses 12, and the eraser 10 is clamped between the two clamping plates. In order to prevent the eraser 10 from falling off, the clamping plates 312 may respectively form plural return portions on the surfaces facing each other. "Return Department" means to make rubber The eraser 10 moves relatively backward with respect to the holding portion 31 more easily than it moves relatively forward, thereby clamping the eraser 10 more reliably.

On the other hand, the connecting plate 314 is arched and slightly bent backward and extends in the up and down direction. When bent in this way, the holder 30 can restrain the front end side ends of the two clamping plates 312 from opening in a direction apart from each other during the cooling of the molding. In addition, the deformation of the connecting plate 314 can be anisotropic, and even after the molded fixture 30 is cooled, the front end portions of the two clamping plates 312 are not easily deformed in a direction separating each other.

The operating portion 32 is protrudingly arranged outside the housing 20 for the user to operate. In addition, in order to enhance the user's sense of operation, the operating portion 32 has a circular arc at its rear end and is tapered toward the front end, and the upper surface of the operating portion 32 is concave and curved. Furthermore, the surface is formed with unevenness as a slip preventing part.

The elastic engaging portion 33 has a plate-shaped upper plate, a middle plate and a lower plate, a rear end curve connecting the upper plate and the middle plate, and a front end curve connecting the middle plate and the lower plate, and is approximately in an inverted S shape when viewed from the side. The elastic engaging portion 33 can be greatly elastically deformed in the vertical direction. The rear end of the lower plate is formed by bending upward. If the rear end of the lower plate is formed in this way, the rear end of the lower plate will not touch the inner peripheral wall of the housing 20 when the holder 30 retreats. Two locking protrusions 332 can be formed on the upper surface of the upper plate of the elastic engaging portion 33 which abuts against the inner peripheral surface of the upper wall of the upper wall of the housing 20, which enclose the insertion plate 34 in the center and face each other. Although the locking protrusion 332 cannot be engaged with the non-locking hole 264 formed in the guide groove 26 of the housing 20 with a narrow groove width, it can be engaged with the locking hole 262 with a wider groove width.

The elastic engaging portion 33 is arranged in the housing 20 under compression in the vertical direction (refer to FIG. 2). In the housing 20, the locking protrusion 332 can be pressed upward from time to time, so that the locking protrusion 332 is engaged with the card.止孔262。 Stop hole 262. By this engagement, the holder 30 can be locked to the housing 20 and cannot be relatively moved in the front-rear direction. On the other hand, when the operating portion 32 is pressed downward, the elastic engaging portion 33 is compressed and elastically deformed, so that the locking protrusion 332 is released from the locking hole 262 of the housing 20, so that the holder 30 can be released from the The housing 20 is locked. If the engagement between the locking protrusion 332 and the housing 20 is released, the holder 30 can move freely in the front and rear directions in the housing 20.

In the free state where the elastic engaging portion 33 is not assembled in the housing 20 (refer to FIG. 10), the rear end of the lower plate connected to the middle plate by the bending of the front end will be located below the front end of the lower plate. If the elastic engaging portion 33 is formed in this way, when the holder 30 is assembled in the housing 20, the contact pressure between the front end of the lower plate and the inner peripheral wall of the housing 20 can be lower than the contact pressure between the rear end of the lower plate and the inner peripheral wall of the housing 20 . With this configuration, the friction force between the front end of the lower plate and the inner peripheral wall of the housing 20 when the holder 30 assembled in the housing 20 is slid in the front-rear direction can be reduced. When 10 is housed in the housing 20, the sliding resistance is reduced. In particular, the sliding resistance when outputting the eraser 10 can be greatly reduced.

The insertion plate 34 is a flat plate that can connect the lower surface of the operating portion 32 to the upper surface of the elastic engaging portion 33 and has a width slightly smaller than the non-locking hole 264 which is narrower than the guide groove 26. The penetration plate 34 is arranged to penetrate the guide groove 26 in the vertical direction, and is in a state where the upper part thereof protrudes from the housing 20. The penetration plate 34 can guide the holder 30 in the front-rear direction and slide in the front-rear direction of the guide groove 26 according to the sliding operation of the operating portion 32 by the user.

The elastic connecting portion 35 has a front extending rearward from the lower end of the connecting plate 314, and a rear extending from above to connect with the front end (upper end) of the upper plate of the elastic engaging portion 33. Inverted L-shaped. The width of the elastic connecting portion 35 is the same as that of the connecting plate 314 and the connecting engaging portion 33, but is smaller than the separation interval in the width direction of the inner peripheral wall of the housing 20. Therefore, the side surfaces of the connecting plate 314, the elastic connecting portion 35, and the connecting engaging portion 33 do not contact the inner peripheral wall of the housing 20. When the eraser 10 is output or the eraser 10 is housed in the housing 20, the holder 30 There is no sliding resistance between the side surface and the inner peripheral surface of the housing 20. Furthermore, the retaining portion 31 of the holder 30 assembled in the housing 20 is elastically engaged The portion 33 and the elastic connecting portion 35 can be accommodated in a cross-sectional area that is smaller than the cross-sectional area of the largest outer shape of the eraser 10 in a direction orthogonal to the axial direction, so that the housing 20 can have a smaller cross-sectional shape.

(Slide operation)

In the elongated object output device 1 constructed as above, the eraser 10 can be housed in the housing 20 when it is not in use. The locking protrusion 332 of the holder 30 will be pressed to engage with the locking hole 262 of the guide groove 26 of the housing 20, and the holder 30 and the eraser 10 will be locked so that they cannot move in the front-rear direction. When the eraser 10 is output, first, the operating portion 32 of the holder 30 is pressed down toward the center axis of the housing 20 to release the engagement between the locking protrusion 332 of the holder 30 and the locking hole 262 of the housing 20. After the engagement between the locking protrusion 332 and the locking hole 262 is released, the holder 30 can move in the front and rear directions in the housing 20. Next, if the operating portion 32 of the holder 30 is slid forward, the eraser 10 held by the holding portion 31 of the holder 30 is output from the opening 22 at the front end of the housing 20. When the pressing of the operating portion 32 is released and the locking protrusion 332 is engaged with the locking hole 262 again, the holder 30 will be locked to the housing 20, and the eraser 10 output from the opening 22 of the housing 20 can be used.

When the operating portion 32 is pressed down while sliding forward, the locking protrusion 332 of the holder 30 will advance with respect to the locking hole 262 and the non-locking hole 264 of the housing 20 while repeating contact and non-contact in sequence. Therefore, the user can perform sliding operations while grasping the position of the locking hole 262 of the housing 20.

In the elongated object output device 1 of this embodiment, the eraser 10 has a concave portion 12, and the concave portion 12 of the eraser 10 substantially penetrates its longitudinal direction and does not approach or contact the inner peripheral wall of the housing 20. Therefore, compared with the conventional elongated object output device, the sliding resistance when outputting the eraser 10 from the housing 20 can be reduced. The same applies when the eraser 10 is housed in the housing 20.

(Use of Eraser)

In this embodiment, the eraser 10 is used in a state where the outer surface of the corner pillar protrusion 14 of the eraser 10 penetrates the length direction of the eraser 10 and is close to or in contact with the inner peripheral wall of the housing 20. Therefore, compared with the conventional elongated object output device, the movement (deformation) of the eraser 10 in the direction orthogonal to the axial direction can be reduced when in use.

Furthermore, in this embodiment, an elastic connecting portion 35 is provided between the holding portion 31 and the elastic engaging portion 33 of the holder 30. The elastic connecting portion 35 connects the lower end of the connecting plate 314 and the upper end of the elastic engaging portion 33 and elastically supports the holding portion 31 of the holder 30 asymmetrically with respect to the axial direction in the axial direction. According to this structure, when a load is applied to the rear of the eraser 10 in the axial direction due to the use of the eraser 10, the elastic connecting portion 35 can be elastically deformed asymmetrically (non-axisymmetrically) with respect to the axial direction. The load behind the direction is released in the direction orthogonal to the axis direction. Since the outer side surface of the corner post protrusion 14 of the eraser 10 is close to or in contact with the inner peripheral wall of the housing 20, when the elastic connecting portion 35 of the holder 30 elastically deforms asymmetrically with respect to the axial direction, the eraser 10 is moved toward the axial direction. The applied load is released from the outer side surface of the corner post protrusion 14 toward the inner peripheral wall of the housing 20, so that the axial load borne by the elastic engaging portion 33 can be reduced. Therefore, the engagement between the locking protrusion 332 and the locking hole 262 can be prevented from falling off due to the use of the eraser 10.

Furthermore, in this embodiment, the connecting plate 314, the elastic connecting portion 35, and the elastic engaging portion 33 of the holder 30 are integrally formed by a single curved plate, and are elastically deformed as an integral elastic member. Therefore, compared with the holder of the conventional elongated object output device, the holder 30 can be elastically deformed with a larger displacement, so that a more durable holder 30 can be provided.

(Assembly)

When assembling the above-mentioned long object output device 1, first, the two opposite recesses 12 (the upper and lower recesses 12 in FIG. 2) at the end of the eraser 10 are fitted into one of the two clamping plates 312 of the holder 30 After time, the eraser 10 is combined with the holder 30. Next, insert the assembled eraser 10 and holder 30 into the rear end of the housing 20 的口内24。 Within the opening 24. The insertion plate 34 of the retainer 30 penetrates the guide groove 26 communicating with the opening 24 at the rear end of the housing 20 in the vertical direction, and the elastic engaging portion 33 of the retainer 30 is compressed in the vertical direction in the housing 20, and the The eraser 10 and the holder 30 are combined in the housing 20. When the holder 30 is moved to any position on the housing 20 where the locking hole 262 of the guide groove 26 is formed, the locking protrusion 332 will be pushed by the elastic engaging portion 33 and be engaged with the locking hole 262 to fix The device 30 is locked to the housing 20. Finally, by combining the cover 40 with the rear end of the housing 20, the elongated object output device 1 can be assembled. The above assembly operation and the disassembly operation of the reverse steps can be easily performed without using tools, allowing the user to easily exchange the eraser 10.

In the present embodiment described above, although the projection 28 protruding toward the center axis is formed in the opening 22, it is not limited to this. In other embodiments, the projection 28 may not be provided. At this time, the effect of suppressing the bending deformation of the eraser 10 in the direction orthogonal to the axial direction will be greater. This is because the cross-sectional shape (area moment of inertia) of the eraser 10 in the direction orthogonal to the axial direction and the exception of the convex portion 28 The outer shell 20 is supported by the eraser 10 generated on the inner peripheral surface. Furthermore, the groove at the front end of the recess 12 can be used as a discharge groove for the eraser chips generated by using the eraser 10. In this case, the eraser 10 can be used more easily. In addition, in the present embodiment, although it is explained that the recesses 12 are formed on the four sides of the eraser 10, as long as the sliding resistance between the eraser and the inner peripheral wall of the housing can be reduced, in other embodiments, the recesses may also be formed in the eraser. At least one of the sides.

Moreover, in the present embodiment described above, the elongated object is an eraser as an example, but it is not limited to this. In other embodiments, blades, pen cores, colored drawing tools, pellets, etc. can also be formed into elongated objects and combined Use any holding part to hold it. In addition, in the description of the elongated object of the present embodiment, the cross-sectional shape in the direction orthogonal to the longitudinal direction has corners and has ridges extending in the longitudinal direction, so that the eraser 10 can be used satisfactorily. However, in other embodiments, the elongated object is in the direction orthogonal to the longitudinal direction The cross-sectional shape of can also have an arc with a predetermined radius instead of corners. At this time, the interference between the corners of the inner peripheral surface of the housing and the ridgeline of the eraser caused by the four corners in the direction orthogonal to the longitudinal direction can be avoided, and the sliding resistance between the eraser and the housing when the eraser is output is further reduced.

The present invention can be implemented in various other forms without departing from its gist or main characteristics. Therefore, the foregoing embodiments are merely illustrative and should not be interpreted restrictively. The scope of the present invention is expressed by the scope of the patent application, and is not limited by the specification. Furthermore, all modifications, various improvements, substitutions and modifications belonging to the equal scope of the patent application are also included in the scope of the present invention.
