A rotary body 6 is attached to the tip of the rotating shaft 19 that protrudes into the inside of the container 4, and a lower coupling 1 is attached to the end that protrudes from the bottom of the container 4.
An upper coupling 20 is fixedly attached to the gear shaft 4 to transmit the rotation of the gear shaft 12 to the rotating shaft 19.

The rotating body 6 is a prismatic column, which is formed to become thinner from the end to the tip, and a rotating shaft 19 that transmits the rotation of the motor shaft 9 is introduced and fixed inside, and is integrally formed with the rotating shaft 19. As a result, the motor 2 rotates and drives the motor 2. Further, the end of the rotating body 6 rotatably contacts the upper end of the guide portion 16, and a step portion 2 protruding in the horizontal direction is provided in the vertical direction of the outer circumference.
1, 22, and 23 are provided at predetermined heights in the form of steps.

Here, the stepped portion 21 is formed by the chopping cutter 7.
The stepped portion 22 is placed in the mounting position a (Fig. 2), and the stepped portion 22 is placed in the mounting position of the Oroshi cutter 7b (Fig. 3).
3 is the installation position of the slice cutter 7c (Fig. 4)
The engagement portions between the rotating body 6 and each cutter 7a, 7b, 7c are stepped portions 21, 22, 23, respectively.

Note that the step portions 21, 22, and 23 are not limited to three steps, and may be formed in as many steps as necessary.

Further, although the rotating body 6 is attached to the rotating shaft 19 as a separate component in this embodiment, it is directly attached to the rotating shaft 19.
Even if a stepped portion is formed at 9, similar effects can be obtained.

As shown in Figure 2, the chopping cutter 7
In the cutter attachment member 8a to which a is attached, the rotating body 6 is introduced into the interior and engaged at the stepped portion 21, and the stepped portions 22 and 23 located upward are covered. Therefore, the stepped portion 21 serves as an engaging portion between the rotating body 6 and the cutter attachment member 8a.

The chopping cutter 7a is attached near the engaging portion of the cutter attachment member 8a, and this attachment point is opposite to the stepped portion 21 so that the stepped portion 21 positions the center of rotation of the cutter 7. located and installed.

Similarly, as shown in FIG. 3, the cutter attachment member 8b to which the Oroshi cutter 7b is attached has the rotating body 6 introduced therein and engaged at the stepped portion 22, and the stepped portion 23 located upward is covered. At the same time, the Oroshi cutter 7b is attached in the vicinity opposite to the stepped portion 22, and the stepped portion 22 serves to position the center of rotation of the Oroshi cutter 7b.

In addition, as shown in FIG. 4, the slice cutter 7

A slice cutter 7c is attached in the vicinity opposite to the slice cutter 7c.
It is used to position the center of rotation.

As shown in FIGS. 2 to 4, each of the cutter mounting members 8a, 8b, and 8c has an upper end opening 24.
is provided, and the width P of this upper end opening 24 is
is formed to be smaller than the width Q of the lower end opening 25 of the engaging portion where the cutter 7 attached to the cutter attachment member 8 engages with the rotating body 6, respectively. Therefore, the cutter attachment member 8 is attached to the rotating body 6.
It is configured so that a, 8b, and 8c cannot be installed in opposite directions.

Also, the gap A between the step portion 23 at the top of the rotating body 6 and the lid 5 and each cutter mounting member 8, 8a, 8b,
The length B (B ₁ , B ₂ , B ₃ respectively) of 8c is A<
B. Therefore, even if the cutter attachment member 8 is turned in the opposite direction and introduced from the tip of the rotating body 6, the lid 5 cannot be closed, as shown in FIG.

Reference numeral 26 denotes a switch that is always off, and is a normally open switch that is turned on by being pressed by a switch operating terminal 27 provided on the cover 5 when the cover 5 is closed. 28 is a handle.

Next, the operation will be explained.

First, when the container 4 is placed on the top surface of the main body 3 while fitting the fitting part 15 of the container 4 into the mounting table part 13 of the main body 3, the upper coupling 20 and the lower coupling 14
are engaged with each other, so that the rotation of the gear shaft 12 can be transmitted to the rotating body 6 fixed to the rotating shaft 19.

Next, a cutter attachment member 8 to which a predetermined cutter 7 is attached is attached to the rotating body 6 protruding into the container 4 depending on the material of the workpiece.

At this time, for example, when using the chopping cutter 7a, the cutter attachment member 8a is attached to the stepped portion 2.
1, and the upper step portions 22, 2 of the rotating body 6
3 is covered, so other Oroshikutter 7b
The slice cutter 7c cannot be attached to the rotating body 6.

After cutting the workpiece into an appropriate size and placing it in the container 4 and closing the upper end opening with the lid 5, when the part of the lid 5 facing the switch operation terminal 27 is pressed, the switch 26 is activated. is turned on, and the motor 2 is driven to rotate. This rotation is transmitted to the gear shaft 12 via the motor shaft 9, pinion 10, and gear 11. The rotation of the gear shaft 12 is controlled by the lower coupling 14,
The signal is transmitted via the upper coupling 20 to the rotating body 6 which is integrally attached to the rotating shaft 19.

When the rotating body 6 rotates, the cutter 7 rotates,
The workpiece in the container 4 is cut.

Here, the gap A between the step portion 23 at the top of the rotating body 6 and the lid body 5 and each cutter mounting member 8, 8a, 8
The lengths B of b and 8c (B ₁ , B ₂ , B ₃ respectively) are:
Since A<B, even if an attempt is made to attach the cutter attachment member 8 by mistake as shown in FIG. 5, the cover body 5 will not be able to be closed, and the switch 26 will not turn on. No, it's safe.

Moreover, cutter mounting members 8a, 8b, 8c
are both upper end openings 24 that are open at the upper ends.
Since the width P is smaller than the width Q of the lower end opening 25 of the engaging portion where the cutter attachment member 8 and the rotating body 6 engage, the cutter attachment member 8 can be rotated with the cutter attachment member 8 in the opposite direction. Even if you try to insert it from the tip of the body 6, it is impossible.

[Effects of the invention] This invention provides a plurality of stepped portions in the vertical direction on the outer periphery of a rotating body rotationally driven by a motor,
A plurality of cutter attachment members are provided which are detachably engaged in correspondence with the step portions at the plurality of places, and each of which has a cutter attached thereto. At the same time, the cutters are attached near this engaging part to position the rotation center of each cutter, so the engaging part between the rotating body and the cutter mounting member matches the cutter mounting location, so the cutter When rotating, the rotational force of the rotating body is reliably transmitted to the cutter without applying any force such as twisting to the cutter mounting member. Furthermore, since the center of rotation of the rotating body and the center of rotation of the cutter coincide, the center of rotation of the cutter can be set accurately, and vibrations and noise can be reduced.

In addition, each cutter mounting member only needs to have a shape that covers only the upper part of the rotating body from the stepped part, so it is smaller than conventional ones, so material costs and mold costs can be saved. .
