The present invention provides a drawing device. A drawing component includes a stage and a drawing head. The drawing head draws on a recording medium supported by the stage. A moving component relatively moves the stage and the drawing head. A position detection component detects a relative position of the stage and the drawing head. An error detection component detects an abnormal state in which an abnormal drawing is performed on the recording medium. When the abnormal state is detected, a controller stops drawing with the drawing head and returns the relative position from the stop position to the position of the drawing start side, so that drawing may be resumed from a position within a predetermined range including the stop position.

An image position measuring apparatus is provided with a photographing unit including an image pickup device and/or a lens to measure a position of a reference mark formed on a work and a correcting unit for correcting distortion(s) of the image pickup device and/or the lens. An exposure apparatus is provided with an image position measuring apparatus and an exposure unit for exposing the work based on image data corrected based on positional information of the reference mark photographed by the image position measuring apparatus. Influences of the distortions of the image pickup device and the lens can be eliminated and accuracy of measurement of the position of the reference mark provided to the work can be improved.

A substrate k1 transported to a measurement position Pa by a substrate transport unit 10A is measured by a measuring head moved to a substrate-measuring position Qa by the drive of a measuring head-moving unit. At the same time, a substrate k2 transported to an exposure position Rb by a substrate transport unit 10B is exposed by an exposure head moved to a substrate-exposing position Sb by the drive of an exposure head-moving unit. Then, the substrate k1 transported to an exposure position Ra by the substrate transport unit 10A is exposed by the exposure head moved to a substrate-exposing position Sa by the drive of the exposure head-moving unit. At the same time, the next substrate k3 transported to a measurement position Pb by the substrate transport unit 10B is measured by the measuring head moved to a substrate-measuring position Qb by the drive of the measuring head-moving unit.
摘要:
A rotating drum in which, when the rotating drum is rotated at high speed, there is no offset between divisional drum parts, there is little imbalance, and a moment of inertia for rotation is small. A drum main body is divided into four drum parts whose cross-sectional configurations orthogonal to an axis are fan-shaped. Female projecting portions and male projecting portions are formed at a pitch dimension having a predetermined fit-together tolerance. Thus, the drum parts can be assembled together with a certain amount of leeway at a time of assembly. After the four drum parts have been assembled together, wires are press-fit in from an end surface side of the drum main body so as to tightly fasten the drum parts. Because the assembled drum main body defines configurations of the drum parts to have point symmetry, imbalance can be made small.

A leading edge chuck provided at a leading edge clamp unit and a trailing edge chuck provided at a trailing edge clamp unit are removable from a rotating drum. Therefore, a direction in which the rotating drum rotates in order for printing plates to be mounted thereon, a direction of rotation when the printing plates are exposed, and a direction of rotation in order for the printing plates to be removed from the rotating drum may all be made into a same, single direction. Accordingly, labor impacting working effectiveness, such as switching the rotational direction of the rotating drum, can be eliminated, and image exposure can be conducted rapidly.
