Abstract

An ink jet recording apparatus comprises a carriage movable in a given direction with a recording head which is detachably mountable on it and provided with discharge ports for discharging liquid. The apparatus is arranged to include a sensor for detecting the presence or absence of the carriage, the recording head, and at least one of the ink containers. This sensor is provided for the main body of the apparatus and positioned within the movable range of the carriage. With this arrangement, it is possible to simplify the structure required for detecting whether or not these vital elements for recording are installed without any auxiliary power-supply or memory means.
