Abstract

PURPOSE: To obtain a programmer which can output complicated change output values according to various change curves, by providing a memory unit, which stores plural comparatively simple change curves, and a decision unit which decides whether repeat conditions are satisfied or not.
CONSTITUTION: Plural comparatively simple temperature rise curves are stored in a temperature programmer previously; and next, when the programmer is operated, a voltage corresponding to the initial temperature is outputted from pulse-voltage converter circuit 28, and the temperature of a column constant temperature oven is held at the initial temperature. After initial time elapse, generated pulses are inputted to converter circuit 28 through temperature rise rate setting circuit 26. Here, a voltage increased linearly in a unit time according to the temperature rise rate and the voltage corresponding to the initial temperature are added and are ourputted to comparator circuit 34 and are supplied to the constant temperature oven as a temperature set voltage. Circuit 34 compares this temperature set voltage with a voltage corresponding to the final temperature; and when they become equal to each other, circuit 34 drives hold timer 36. After hold time elapse, the temperature set voltage is defined as the initial temperature for the next temperature rise curve after advancing the temperature rise curve to the next temperature rise curve by SEG key decision circuit 42.
