Regarding these two machines, Todd Scott said: "Since you came up with your idea, we tried it for a long time before we built this machine, and it worked exactly as you imagined."

He pointed to a larger typewriter and said, "This is a modified typewriter. In addition to its normal functions, it can also output text content through punching cards."

As he said that, he opened the cover of the typewriter, exposed the keyboard inside, put a piece of white paper in, rolled it a few times and adjusted it. However, he did not start typing the keys, but put a card in another place.

After adjusting these, he started typing, and soon a line of text appeared on the white paper.

"the                                                                                                                                                                                                                                                              �

Then Todd Scott stopped, took out the white paper and handed it to Jing Yu for a look. Because there was only very simple content on it, Jing Yu glanced at it and nodded. Scarlett Saimen next to him was also sitting in a wheelchair and stretched over to try to see it. Jing Yu handed the paper over to her.

At this time, Todd Scott pulled out the card card from under the typewriter. There were many dense holes on the originally flat and smooth cardboard, about the size of soybeans, but it seemed that there were many burrs on the holes. Jing Yu took them and stroked them gently with his hands, feeling them, feeling that the hole drilling effect was not very good.

Todd Scott opened the punch card that Jing Yu returned to another obviously larger square machine, inserting it vertically like an old attendance punching machine, then putting a piece of white paper, and then began to shake the handle on the square machine.

Soon the gears sounded in the machine, and the reeds were running and knocking. After Todd Scott shook a few times, a dinging sound came out. Todd Scott stopped turning the handle.

He took out the piece of white paper he had just put in and handed it to Jing Yu.

The above also uses upper and lower case, which shows itself "the                                                                                                                        �

"Mr. Jing," said Todd Scott, "We do this according to your ideas, so that as long as we have a punch card entered in advance, we can easily type out a document repeatedly."

Looking at this effect, Jing Yu, who was used to modern copiers, looked down on this method of copying manuscripts that rely on mechanical originals, had to accept Todd Scott's mechanical talent. He did not expect that the other party would actually make the machine he proposed casually.

Although Jing Yu's opinion still has many improvements to these two machines, Jing Yu is very impressed by the ability to realize this function by relying entirely on mechanical structure.

Speaking of which, the principle of the machine is very simple. It is to use different holes to represent upper and lower case letters. Symbols include spaces and line breaks. Jing Yu asked Todd Scott. The other party replied that they retained 8 hole-punchable positions in a grid, because each position has two states: punching holes and not punching holes. In this way, each grid will have eight square combination methods, that is, 64 types, and 26 English letters are divided into upper and lower case, which occupies 52. In addition to some comma periods, colon quotes and other symbols, there are still a few left for future settings.

Then after this punch card is sent to another machine, the machine can try to see if the corresponding position has been punched by extending 8 probes to each grid, and then through a series of complex mechanical structures such as gears, the letter symbols corresponding to the punch card are called out, and the self-touching rod is activated through a mechanical transmission device, and the corresponding letter symbols are tapped on the white paper, which eventually forms the text content entered on the typewriter.

It is such a function. Jing Yu can imagine how much time and effort it took to make these two machines realize in a purely mechanical way.

However, in this way, each character position needs to be recorded with one grid, that is, eight punching points, and the result is that compared to directly writing, the same piece requires more punching cards to record.

It is the phrase with 26 letters that can be displayed on the paper with less than a line of space, but switching to the punched card requires several times the space to save the same amount of content.

Alice Herbert said at this time: "Mr. Jing, you have also discovered that for punching cards, a slightly longer article requires many cards to record. This is very troublesome and difficult for users to accept. Do you know if Mr. Jing has any suggestions or other ideas for this machine?"

Jing Yu also felt the same about Alice Herbert's idea. He had not carefully considered this issue before, but he still remembered that he had mentioned to Alice Herbert that there was no need to make the punched card paper thick and hard, and it was possible to make the punched paper soft and strong long straps, and then a large scroll disc similar to an old film movie player. This would be easier to store and would not be like punched cards one by one. If you make the order of the punched card incorrectly, it would be wrong to make the punched paper in the wrong order.

In addition, the working principle of this machine made Jing Yu involuntarily think of the "Enigma" cipher machine. If this machine is equipped with several key disks to control character transposition rules, it is possible to create a simple version of the "Enigma" cipher machine. However, this pure mechanical method will definitely not have hundreds of millions of combinations like the "Enigma" cipher machine that uses electricity.

But this is not bad. Jing Yu feels that the government and some commercial institutions will definitely have the need to encrypt important information. Since this machine is not particularly suitable for repeated printing of documents, it may be a good choice for encryption.

But in this way, Jing Yu still wanted to register the patent first, so he said: "I have to think about this matter carefully and see how to improve it."

Alice Herbert agreed without a doubt, and Todd Scott couldn't help but say, "Mr. Jing, if you can go to Herbert's factory next time, it's best. We can adjust the machine directly in the factory."

Jing Yu also thought about it. It seemed that Ralph Stamford had not come back in the New World for a while, so he did not directly agree and replied: "It depends on the situation."

Alice Herbert was very happy to hear that Jing Yu did not refuse directly like before, because she didn't know Jing Yu's idea, but instead felt that Jing Yu was finally willing to go to Herbert's factory.
