Document Type and Number:
Japanese Patent JPH0752387
Kind Code:
A
Abstract:

PURPOSE: To make an apparatus compact and improve the reliability by suitably arranging a constitution to control a temperature of an inkjet recording head.

CONSTITUTION: On a substrate 101 constituting a recording head where a discharge heater and the like are formed, there are provided a temperature sensor 10'7 for detecting a temperature of the recording head and, a constitution for driving temperature controlling sub heaters 108-1 and 108-2 on the basis of the detection, that is, an analog voltage converter, an amplifier, a comparator and a sub heater driver. Accordingly, a space at the side of a main body of the apparatus is saved and the number of signal wirings is reduced to prevent the deterioration of reliability resulting from the connection of wirings.
