BLOG 3.  “Japanese innovated the clock showing the irregular time system.”

Karakuri Zui explains how to make various karakuri. Here are two pictures of my book JAK. The left page of the first picture is the drawing of the original first page of Karakuri Zui to make the Japanese pillar clock, and the left page of the second picture is the original first page to make the tea serving automaton. The red lines and alphabets of the original drawings were attached by me.

In the original book, the author Hosokawa Hanzo Yorinao (c.1749-96) explains about three kinds of Japanese clocks and nine kinds of automatic mechanical toys. In the end of the part of the clocks of the book, Hosokawa points out that the clock is the essence of karakuri.

Japanese innovated the mechanical clock showing the irregular time system which was improved from the Western mechanical clock. When you want to know the mechanism of such Japanese clocks, please read my book Japanese Automata Karakuri Zui.
