Patent Images
1. A temperature measurement device comprising:
- a single operator actuatable switch manipulatable from outside the device, said switch having open and closed states;
temperature measurement means for measuring a temperature of interest and developing a temperature signal representative thereof;
judging means, monitoring said operator actuable switch, for detecting whether said dswitch is in said open state or in said closed state;
recording means for storing sid temperature signal developed by said temperature measurement means; and
display means for displaying a temperature represented by a temperature signal provided thereto;
said judging means, upon detecting said switch is in said closed state, recalling the temperature signal representative of a previous temperature stored in said recording means and supplying said temperature signal to said display means for display thereon, said judging means, upon detecting an open state of said switch subsequent to said closed state, supplying the temperature signal developed by said temperature measurement means and representative of a current measured temperature to said display means for display thereon;
said previous temperature being displayed on said display means for as long as said switch is held in said closed state.

Abstract
In a temperature measurement device, output signals from a temperature measuring sensor having been stored in a recording element are displayed when a judging element detects that a manipulatable switch is closed. Temperature measurement is begun including displaying the temperature when said judging element detects that the switch is opened after it is closed.
