An object is to provide a printing apparatus or the like that improves printing accuracy when a carriage moves back and forth for printing. A block 51 on a block surface plate is mounted on the block surface plate at a predetermined location. On the other hand, a substrate 54 on a print surface plate is mounted at a location corresponding to the location of the block 51, that is, a location where a picture transfer is desirably received from a blanket cylinder 13. In the present invention, the arrangement of sliders 52 and 40 for the block carriage 50 and a printing carriage 7 to reciprocate along two rails 30 in the block carriage 50 and that in the printing carriage 7 are the same. With such an arrangement, at the same location immediately below the blanket cylinder 13 on the same track 30, even when the straightness of the rail 30 is not sufficient, the block 51 and the glass substrate 54 take the same position at the location, and thus print misalignment can be prevented.

An objective is to provide an automatic cleaning device for machine tool in which cleaning efficiency is improved by performing cleaning for a large range during machining. To achieve this, an air nozzle (21) that removes, by air-blowing, chips (Wa) and cutting oil (C) dispersed while a workpiece is being machined to an outside of the machine is allowed to move not only independently from a movement of a spindle head (16), but also relatively to a workpiece (W) in directions of three orthogonal axes.
