Description

  The present invention relates to a pencil sharpener that electrically cuts a pencil, and more particularly, to an electric pencil sharpener with a residue removal mechanism equipped with a function for removing residues such as a broken core of a pencil that cannot be removed inside the cutting mechanism. The present invention also relates to an electric pencil sharpener with a residue removal mechanism equipped with a safety device composed of three sensors.

  Conventionally, in addition to a manual pencil sharpener that manually drives the cutting mechanism to cut the pencil, the pencil sharpener has an electric pencil sharpener that drives the cutting mechanism by an electric motor or the like to cut the pencil. In home and office pencil sharpeners, electric pencil sharpeners that are highly convenient and efficient are widely used. In this electric pencil sharpener, generally, a switch having a protruding (convex) sensor provided in a penetrating hole of a pencil provided in the electric pencil sharpener body is contact-pressed by the inserted pencil. The driving mechanism is operated, and the tip of the pencil is cut by rotating the cutting mechanism.

  As a problem when using this electric pencil sharpener, the pencil core remains broken during the process of inserting and cutting the pencil into the penetration hole, or a short pencil or an erroneously inserted eraser is left inside the penetration hole. As a result, the sensor protrusion of the switch returns to the original state, and the drive mechanism becomes inoperable, and it becomes difficult to take out these residues, which may cause a situation where the pencil cannot be scraped. . Further, in this case, it is considered that the residue is discharged from the penetration hole by turning the electric pencil body upside down. However, the protrusion (protrusion) provided in the penetration hole for operating the drive mechanism is considered. When these residues enter the back of the switch, the sensor protrusion of the switch makes it difficult for the residues to come out, and there is a problem that it may be impossible to take out.

Japanese Patent No. 3505144, Japanese Patent No. 3899113, and Japanese Patent No. 2813958 are examples of electric pencil sharpeners equipped with a residual removal mechanism.
In Japanese Patent No. 3505144 and Japanese Patent No. 3899113, the residue in the pencil penetration hole comes into contact with the residue and discharges the residue from the cutting station, and the discharge operation for operating the discharge means from the outside. Techniques for discharging by means are disclosed. Japanese Patent No. 2813958 discloses a technique for pushing and ejecting the broken core clogged in the pencil insertion hole toward the opening direction of the pencil insertion hole by a push operation via a button provided in the pencil sharpener body. .

  However, in Japanese Patent No. 3505144 and Japanese Patent No. 3899113, in the structure in which the projection-like (convex) switch for operating the drive mechanism is provided in the penetration hole, these broken cores and short are behind the sensor projection When a foreign object such as a pencil enters, the residue is moored in the back of the switch, and there is still a problem that it is difficult to discharge the residue from the penetration hole to the outside. Japanese Patent No. 2813958 is a technique related to a manual pencil sharpener, and thus the above switch is not necessary. However, when applied to an electric pencil sharpener, the same problem as described above occurs, and the residue is inserted into the penetration hole. There was a problem that could not be discharged from the outside.

Moreover, since the electric pencil sharpener has a structure in which the cutting blade is rotated and rotated electrically, a safety device has been provided in order to prevent accidental injury. In particular, in the case of discharging the residue from the penetration hole to the outside, it is assumed that the shavings bin or the lid provided on the electric pencil sharpener body is opened to visually recognize the inside of the electric pencil sharpener, It is necessary to prevent the drive mechanism of the electric pencil sharpener from operating unexpectedly.
Japanese Unexamined Patent Application Publication No. 2008-137206 is a technology related to a safety device provided in the electric pencil sharpener. However, here, only one infant protection switch is provided, and if this switch is in a pressed state, the drive mechanism operates, which is insufficient as a safety device.

From the above, the development of an electric pencil sharpener equipped with a mechanism for reliably discharging the residue from the penetration hole is awaited, and further development of an electric pencil sharpener equipped with a reliable safety device has been awaited. .

Further, a scrap receiving box 24 is provided at the lower front of the main body 20, and the remaining scraps of the pencil cut by the cutting mechanism 40 are dropped and stored here.

  The drive mechanism is installed inside the main body 20 of the electric pencil sharpener and includes a drive source (not shown) connected to a power supply source and a gear (not shown) for transmitting power. The driving source (not shown) uses a motor in this embodiment. The motor is supplied with electric power from an electric power supply source, and transmits power to the gear of the transmission mechanism 30 by a gear. In this embodiment, electric power is externally used as a power supply source (not shown).

The transmission mechanism 30 includes a gear or a male / female engaging body that transmits the rotational operation from the drive mechanism. Gears (male and female engaging bodies) constituting the transmission mechanism 30 are joined to the cutting mechanism 40, receive a rotational operation from the drive mechanism, and transmit a rotational force to the cutting mechanism 40. In the embodiments of claims 2 and 3, gears constituting the transmission mechanism 30 (male and female engaging member), the engaging gear (male and female cutting mechanism 40 as shown by the exploded perspective view of the cutting mechanism of FIG. 4 The engaging mechanism 42 is joined to the second gear (second male / female engaging body) 42 b, receives a rotational operation from the drive mechanism, and receives the rotational force via the engaging gear (male and female engaging body) 42. To communicate. As shown in FIG. 3, the transmission mechanism 30 uses gears (male and female engaging members ) in this embodiment, but may be of a type that receives a rotational operation from a drive mechanism using a belt, a chain, or the like. Further, the transmission mechanism 30 can be detached from the cutting mechanism 40 main body or the second gear ( second male / female engaging body ) 42b of the cutting mechanism 40 main body or the engaging gear (male / male engaging body ) 42 and the main body 20 so that repair and replacement are possible. It is desirable to install in a stable state.

  The cutting mechanism 40 is a member provided with a blade that rotates and cuts a pencil. The cutting mechanism 40 is provided with a rotary cutting blade 44 and a penetration hole 50. When the pencil 90 is inserted into the penetration hole 50, the cutting mechanism 40 has a movable protrusion 52 provided in the penetration hole 50 into which the pencil is inserted. The operation switch of the drive mechanism is moved from the inside of the penetration hole by the insertion pressure of the pencil to detect the insertion of the pencil, and the drive mechanism is activated. The rotation operation is transmitted from the transmission mechanism 30 to the cutting mechanism 40, and the rotary cutting blade 44 rotates around the pencil 90 about the penetration hole 50, whereby the pencil 90 is cut.

As Example 1 of the removal mechanism 60, an operation switch 62 is provided that operates the movable protrusion 52 functioning as a sensor provided in the through hole 50 from the outside of the through hole 50 to slide out of the through hole.

  As shown in FIGS. 2 and 8, the inner lid 70 is provided inside the cover 22 of the main body 20. The internal lid 70 has a through hole 50 and is provided with an operation switch 62. The operation switch 62 is a slide member that moves by operating the movable protrusion 52 provided in the through hole 50 from the outside of the through hole 50. When the movable protrusion 52 returns to a state where the original pencil is not pressed while a foreign object such as a broken core or a short pencil has entered from the movable protrusion 52 provided in the penetration hole 50, the protruding operation switch Residue is blocked by the movable protrusion 52 and cannot be taken out. By operating the operation switch 62 provided on the inner lid 70, the movable protrusion 52 is moved from the inside of the penetration hole 50, and the moored state of the residue is released. As a result, it is possible to easily remove the residual material that cannot be removed inside the cutting mechanism even when the drive mechanism is stopped.

  The moving operation of the movable protrusion 52 of the operation switch by the operation of the operation switch 62 is preferably a form in which the protrusion enters the outside from the inside of the penetration hole 50, but may be a form in which the protrusion falls down in parallel with the inner wall of the penetration hole 50. The operation switch 62 may be of a type that moves together with the operation switch 62 in a state of being directly joined to the movable projection 52 of the operation switch, or may be a type that moves the movable projection 52 of the operation switch electrically. In this embodiment, the operation switch 62 is provided on the inner lid body 70 and can be operated from the outside of the cover 22 by providing an opening in the cover 22, but the installation location of the operation switch 62 is not limited.

Example 2 of the removal mechanism 60 has a configuration in which the cutting mechanism 40 is detachably mounted on the main body 20 of the electric pencil sharpener 10 via the engaging portion 41. In this embodiment, as shown in FIG. 4, the cutting mechanism 40 is provided with an engagement gear (male and female engagement body ) 42. The engaging gear (male and female engaging body) 42 is provided with a first gear (first male and female engaging body ) 42a on the cutting mechanism 40 side, and a second gear (second male and female engaging body) 42b on the transmission mechanism 30 side. Consists of configuration. When the first gear (first male and female engaging body ) 42a and the second gear ( second male and female engaging body) 42b are engaged , the rotation operation from the drive mechanism is transmitted from the transmission mechanism 30 to the cutting mechanism 40, and the cutting is performed. When the mechanism 40 operates, the pencil can be cut. Further, the cutting mechanism 40 is attached to the main body 20 so as to be sandwiched between the internal lid 70 and the transmission mechanism 30, and can be removed by opening the internal lid 70 as shown in FIG. The cutting mechanism 40 can be easily detached from the main body 20 of the electric pencil sharpener 10, thereby removing residuals that cannot be removed inside the cutting mechanism 40 and facilitating reassembly. It became.

  In this embodiment, the inner lid body 70 is attached to the main body 20 by screws. However, the coupling method is not limited to this embodiment, and for example, a door body having a lock mechanism for easier operation. It is good also as a form using.

The first and second embodiments are not limited to selectively performing either one. That is, the removal mechanism 60 using the operation switch 62 that moves the movable protrusion 52 provided in the penetration hole 50 by operating from the outside of the penetration hole 50 is installed, and at the same time, the body 20 of the electric pencil sharpener 10 is cut. It is also possible to install a removal mechanism 60 in which the mechanism 40 is detachably mounted via an engagement gear (male and female engagement body) 42. This facilitates the removal of the remaining residues that cannot be taken out into the cutting mechanism even when the drive mechanism in which the movable projection 52 of the operation switch protrudes into the penetration hole is stopped, and makes the cutting mechanism 40 easy to use the electric pencil. Since it is possible to remove the residual material that cannot be taken out from the main body 20 of the shaving machine 10 and remain in the cutting mechanism 40, and to facilitate reassembly, it is easier and more reliable to enter the inside of the through hole 50. It was possible to remove the residue.

The engagement gear 42 includes a first engagement gear (first male and female engagement body ) 42a and a second engagement gear ( second male and female engagement body) 42b. As shown in FIGS. 5 and 6, the first gear (first male and female engaging body) 42 a is a male or female gear mounted at the tip of the cutting mechanism 40, and the second gear ( second male and female engagement). coalescence) 42b is a gear female or male shape corresponding to the male or female shape equipped in the transmission mechanism 30. With this configuration, the engagement between the transmission mechanism 30 and the cutting mechanism 40 via the engagement gear (male and female engagement body) 42 becomes more accurate, and the rotational force used for the rotary cutting is caused by the detachable engagement. It is now accurately communicated.

In this embodiment, the first gear (first male / female engaging body ) 42a and the second gear (second male / female engaging body) 42b have the corresponding male or female shape, but are limited to this shape. is not. For example, in order to enable transmission of rotational force in the opposite direction and to make the engagement between the transmission mechanism 30 and the cutting mechanism 40 accurate, it is conceivable to use gears with a sharper angle or male and female meshing members. It is done.

  In the safety device 80, since the electric pencil sharpener 10 has a structure in which the rotary cutting blade 44 is electrically rotated, the operation of an unintended drive mechanism is suppressed to prevent accidental injury and the electric pencil sharpener 10 can be safely operated. It is a device provided to use The safety device 80 has a structure in which at least three sensors are provided in the main body 20 of the electric pencil sharpener 10. The drive mechanism operates when all the sensors are in the operating position. As a result, the operation of the drive mechanism not intended by the user is suppressed to prevent accidental injury, and the electric pencil sharpener 10 can be used more safely.

  The sensor provided to the safety device 80 includes a first sensor 82a and a second sensor 82b. As shown in FIG. 7, the first sensor 82 a is a sensor that detects that the cover 22 provided on the main body 20 of the electric pencil sharpener 10 is closed by pressing a protrusion 84 provided on the cover 22. In addition, the second sensor 82b is a sensor that detects that the scrap receiving box body 24 is inserted by pressing a projection 86 provided on the scrap receiving box body 24.
