Cutting processing device

1. A cutting processing device for performing a cutting process on a cutting target by use of a rotatable tool, the cutting processing device comprising:

a cutting unit that includes the rotatable tool;

a holding tool configured to hold a plurality of the cutting targets at the same time; and

a rotation support unit configured to rotatably support the holding tool; wherein

the cutting unit is configured to move with respect to the holding tool

the holding tool extends in a direction in which a rotation axis of the holding tool extends away from the rotation support unit;

the holding tool includes a plurality of securing portions that are located along the rotation axis of the holding tool and hold the cutting targets

the securing portions include first, second, third, fourth and fifth securing portions;

the first securing portion, the second securing portion, the third securing portion, the fourth securing portion and the fifth securing portion are arranged along the rotation axis of the holding tool in this order;

the first securing portion and the third securing portion are spaced from each other by a first gap;

the third securing portion and the fifth securing portion are spaced from each other by the first gap;

the first securing portion and the second securing portion are spaced from each other by a second gap that is smaller than the first gap;

the second securing portion and the fourth securing portion are spaced from each other by the second gap;

the fourth securing portion and the fifth securing portion are spaced from each other by the second gap;

in a case in which the cutting targets are first cutting targets, the first cutting targets are respectively secured to the first securing portion, the third securing portion and the fifth securing portion; and

in a case in which the cutting targets are second cutting targets that are smaller than the first cutting targets, the second cutting targets are respectively secured to the first securing portion, the second securing portion, the fourth securing portion and the fifth securing portion.

2. A cutting processing device according to claim 1 , wherein:

pins to be secured to the securing portions are respectively attached to the cutting targets; and

the securing portions include holes engageable with the pins inserted thereinto.

3. A cutting processing device according to claim 2 , wherein in a state in which the cutting targets are held by the holding tool, the cutting targets or the pins overlap the rotation axis of the holding tool.

4. A cutting processing device according to claim 2 , wherein:

the cutting targets each include, attached thereto, a plate-shaped member that includes a cut-off portion and is located between the cutting target and the pin; and

the holding tool includes protrusions each engageable with the cut-off portion.

5. A cutting processing device according to claim 1 , wherein:

the holding tool includes a support shaft supportable by the rotation support unit, a plate-shaped member connected to one end of the support shaft, and a securing member that is connected to the plate-shaped member and extends in a direction in which the rotation axis of the holding tool extends away from the support shaft; and

the securing portions are located at the securing member.
