Abstract

PURPOSE: To indicate the quantity of a humidity senstive body that expands and contracts in a magnified value, by a mechanism wherein the humidity sensitive body is spanned on to a several number of rolls, distance between the one section is formed so that it can be changed, and the quantity of the whole humidity sensitive body that expands and contracts is concentrated to one section.
CONSTITUTION: A rotating plate 11 revolves in response to the extension of a humidity sensitive body 14. The revolution of the rotating plate 11 is transmitted to a humidity sensitive, rotary displacement signal disc 34. A light-and-darkness boundary line of X-X' moves in response to the quantity of the signal disc 34 that rotates. The movement is detected by means of a differential amplifier head 35, a slider 46 with a recording pen is slid by the detecting output, and the change of humidity is recorded to recording paper shifting with time.
