A liquid discharge head includes a liquid discharge substrate that has a discharge-orifice row, pressure generating elements, and pressure chambers. The liquid discharge head discharges a liquid in a block-by-block manner using sequential driving. The discharge-orifice row is disposed so as to incline at an angle θ=Arctan (d1/d2) relative to a direction extending orthogonal to the conveyance direction of the medium, in which d1 (μm) is a disposition spacing of the discharge orifices in the discharge-orifice row in the conveyance direction and d2 (μm) is a disposition spacing of the discharge orifices in the discharge-orifice row in the direction orthogonal to the conveyance direction. A partition wall is formed between adjacent pressure chambers so as to separate the adjacent pressure chambers from each other. The partition wall has a communicating portion that communicates the adjacent pressure chambers with each other.

A control method analysis unit acquires a correspondence relation between signs and model numbers from an apparatus table of an instrumentation diagram, and acquires signs and apparatus symbols, and connection relation among apparatuses, from a drawing of the instrumentation diagram. Subsequently, the control method analysis unit acquires an apparatus classification drawn on the diagram by searching an instrumentation apparatus classification database based on the model numbers, and decides a temperature control method employed by an instrumentation indicated in the instrumentation diagram, from the apparatus classification and the connection relation. The control method analysis unit then links the decided temperature control method to the instrumentation diagram accumulated in a case database. A search processing unit extracts a corresponding instrumentation diagram by searching the case database based on a temperature control method designated as a search condition.
