The mechanism of the crossbow is that if you say it very roughly, you put up a clamping stick on the string of the bow you put up, and if you remove it, the arrow will be released.

That said, it really doesn't work with the mechanism as it is, so we need to make it a slightly more elaborate mechanism.

The mechanism actually incorporates a portion of the disk that is fixed to the center is chipped into the concave shape and catches the strings strung thereon. Of course, the disc turns around with the tension of the string, and the arrow is immediately released.

Therefore, a cutout is made on the opposite side of the concave shape, and a different part is combined to suppress the rotation. When the part moves, the rotation that was suppressed is performed with the tension of the string, and at the same time, the string that was caught in the cutout is released and the arrow is released.

A moving part is the part that hits the trigger that is also present in the gun. It was similar to releasing a fixed strike iron in conjunction with the reverse force.

After the trigger is pulled, it must be returned to its original position. It may simply be used around the tension coil spring, but this time, the plate spring is made into a U-shape.

In the previous world, firecracker guns are similar in shape to pine leaf gold, furry gold, or pop gold.

Because practical coil springs are a little bit ahead of the world today. In the previous world, that great genius, Leonardo da Vinci, had left a sketch, so if a similar genius appeared, the time would be faster.

But I'm not going to be Da Vinci much. The original technology has existed for quite a long time - that's why bows are also possible in a sense - and I think that suspension in the application of leaf springs is a very tight line.

Speaking of which, Zenmai, a form of whirlpool spring, thinks that it may be almost OK, but for now, I don't have the opportunity to use it, so I won't be here for a while.

"I can't think of anything but Lucy's toys to do with Zenmyi Power..."

And the trigger was not a thin shape that I could think of as a trigger, but a lever-shaped one.

The parts of what is called the Engineering Department will be made into tricks. The work goes smoothly thanks to cheat. It's good to be able to get help, even if it's not just a product like a sword or a sword.

Well, if you want to make a sword or a sword by yourself, you'll need to build parts, so maybe you can help me as a "sword".

Not only tapping with a hammer, but also occasionally chopping it off with a handkerchief. Then combine each. Instead of a shaft, the nail is fixed to a mere wooden board. If we just check the operation for now, this won't be a problem.

Are you going to try it?

"Oh, you see?"

Of course!

Riquet, who seemed to be praising the situation, answered vigorously. There is no doubt that Krull and the others would have come to see what would have happened.

The disk has a concave notch, and the notch is facing upwards. On the opposite side, it was cut into the shape of a beam, and the tip of the lever that triggered it to fit there was holding back the rotation.

A hairpin-like leaf spring is laid under the lever tip, and the lever tip is pushed upward under tension, and the rear end is pushed down about the axis.

I put my finger on the concave shape of the disc and put tension in front of it. I decided to ask Riquet to operate the lever because it was a big deal.

Is that okay?

"Just watching the moves, no problem." Do it. "

Ok, then.

Terrified, Riket pushed up the back end of the lever. The lever tip is lowered and the lever spring is compressed.

When the tip came off the disk, the suppressed rotation began, and the concave notch turned forward. If this is a bow string, it will be released and arrows will be released at this point.

On top of the lowered lever tip, a small portion of the disc is inserted so that it can sit.

When I release my fingers from the disk and get my hands off the lever, the lever tip rises due to the tension of the lever spring. The disk that was not subjected to any force is pressed against the lever tip and rotated so that the concave notch is raised.

Then, the disc and the tip of the lever meshed again and were fixed. This brings us back to the original state.

When it is actually used as a crossbow, after this, the bow strings are tensioned to enter the notch again, and the arrow (it is a special thick arrow) is held and ready for firing.

You're doing great.

Yeah, let's see if we can actually team up and move properly.

Even if it works when I try it like this, it's normal to say that it doesn't work when I actually put it together.

Even in the previous world, it was successful during development, but it was not difficult once or twice without the operation that I thought would be the real thing.

As I prayed not to, I removed the mechanism I had put together in order to move it to production.
