Description

  The present invention relates to an electric pencil sharpener.

Conventional electric pencil sharpeners are known to be operated by inserting a pencil in a horizontal direction (lateral direction) and operated by inserting a pencil in a vertical direction (vertical direction). A conventional electric pencil sharpener for inserting a pencil in the horizontal direction is shown in FIG. 5 (see, for example, Patent Document 1), and a conventional electric pencil sharpener for inserting a pencil in the vertical direction is shown in FIG. 6 (for example, in Patent Document 1). 2). In FIG. 5, a main body case 18 houses a motor and a cutter (not shown), and a receiving box 19 is detachably attached to the main body case 18 to store pencil shavings. The power cord 21 supplies power to the motor. When the power cord 21 is attached to an outlet and a pencil is inserted into the pencil insertion slot 20 in the horizontal direction, the motor rotates and the pencil is shaved. Also in FIG. 6, as in the conventional electric pencil sharpener of FIG. 5, the main body case 22 houses a motor and a cutter (not shown) inside, and the receiving box 23 is detachably attached to the main body case 22. Pencil shavings are stored, and the pencil is shaved when the power cord 25 is attached to an outlet and the pencil is inserted into the pencil insertion slot 24 in the vertical direction.

  However, with a conventional electric pencil sharpener, the insertion of the pencil is fixed in the horizontal direction (horizontal direction) or the vertical direction (vertical direction), so if it is horizontal direction insertion, Pencil insertion is relatively easy, but when it is placed at hand, the insertion operation becomes tight. In addition, in the case of vertical insertion, if it is installed on the back side of the desk opposite to the horizontal direction, the upper body must be bent and the pencil must be held, but if it is installed at the hand, the insertion operation is the shortest distance. It becomes easy. As described above, there is a problem that the optimum installation place is limited by each pencil insertion type of electric pencil sharpener.

  In order to solve the above-described conventional problems, the pencil sharpener of the present invention is detachably attached to a motor, a cutter that is driven by the motor to rotate, a main body case that houses the motor and the cutter, and the main body case. A receiving box, a stand that rotatably holds the main body case with a predetermined position of the main body case as a rotation fulcrum, and a fixing means that enables at least two relative positions of the main body case and the stand. It is something that. With the configuration of the present invention, the pencil insertion angle can be freely set.

  In addition, the main body case has a convex portion arranged in one of the receiving box and a concave groove arranged to be fitted to the convex portion on the other side, and the receiving box is attached to and detached from the main body case. In doing so, the convex portion relatively moves in the longitudinal direction of the concave groove, so that it is not necessary to store a portion for storing pencil shavings in the main body case.

  Further, since the wiring cord for supplying electric power to the motor passes through the hole provided in the rotation fulcrum, the power cord can be led out from the stand.

According to the present invention, since the pencil insertion angle can be set freely, an electric pencil sharpener capable of selecting a form with good operability according to the installation location can be obtained.

  Moreover, since it is not necessary to store the part which stores pencil shavings in the inside of a main body case, the amount of pencil shavings in a receiving box can be visually recognized with respect to any angle of a main body case.

  Further, since the power cord is led out from the stand, the power cord is not swung around by changing the angle of the main body case.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

(Embodiment 1)
1A is a perspective view of a state in which a pencil is inserted horizontally in the electric pencil sharpener in Embodiment 1 of the present invention, and FIG. 1B is a state in which the pencil of the electric pencil sharpener is inserted in the vertical direction. FIG. 1C is a perspective view of a state in which the pencil of the electric pencil sharpener is inserted obliquely downward, and FIG. 2 is a cross-sectional view of the main case of the electric pencil sharpener in the first embodiment. FIG. 3 is a cross-sectional view of the main part of the stand of the electric pencil sharpener according to the first embodiment, and FIG. 4 is a cross-sectional view of the main part of the receiving box mounting portion and the stand of the electric pencil sharpener according to the first embodiment. In FIG. 1, a main body case 1 has a pencil insertion opening 1a on the front surface, and a motor 2, a gear 3, a gear 4, a gear 5 for transmitting rotation of the motor 2 as shown in FIG. A cutter 6 having a cutting blade and a cutter holder 7 for holding the cutter 6 are housed. When a pencil is inserted into the pencil insertion slot 1a, a switch (not shown) is turned on, and the motor 2 is energized. The receiving box 8 stores pencil shavings and is detachably attached to the main body case 1 in the direction of arrow A in FIG. Here, the B portion of the main body case 1 has a pair of convex portions 1b on the inner side as shown in FIG. 4, and the main body case 1 and the receiving box 8 are mounted by fitting with the concave grooves 8b of the receiving box 8. Is done. The stand 9 rotatably holds the rotation fulcrum 10 of the main body case 1. As shown in FIG. 3, a cam 11 integrally formed with the main body case 1, a pair of cam levers 12 that are rotatably attached to a rotation shaft 12 a as a fulcrum, and a spring attached to the cam lever 12. 13 is stored, and the main body case 1 is fixed at several predetermined positions, and when the main body case 1 is rotated, it has a click feeling. A power cord 14 is attached to the bottom of the stand 9, and the wiring cord 15 passes through a hole 10 a provided in the central portion of the rotation fulcrum 10 of the main body case 1 and is led into the main body case 1. It is connected to a motor 2 and a switch (not shown).

  1A, 1B, and 1C, the main body case can be adjusted to a free angle with respect to the stand about the rotation fulcrum as shown in FIGS. The pencil insertion angle with the best pencil insertion operability can be set freely.

  In addition, when the main body case or the receiving box has a convex portion disposed on one of the main body case and a concave groove disposed on the other side so as to be able to be fitted to the convex portion, In the case of the pencil vertical insertion specification as shown in FIG. 1 (b), it is not necessary to store the portion for storing the pencil shavings by the relative movement of the convex portion in the longitudinal direction of the concave groove. However, it is preferable in that the amount of shavings in the receiving box can be visually recognized by making the receiving box a translucent material.

  In addition, since the power cord is led out from the stand because the wiring cord passes through the hole provided at the rotation fulcrum to supply power to the motor, the power cord is swung by changing the angle of the main body case. It is preferable in that it does not occur.

In this embodiment, the cam is used as the fixing means. However, a clutch having a predetermined torque that can be adjusted steplessly may be used. Alternatively, a means for fixing with a screw or the like after adjustment may be used. good.

    The electric pencil sharpener according to the present invention is useful as an electric pencil sharpener with good operability for pencil insertion at any installation location.
