Abstract: At least both sides of the recording medium (10) are sandwiched by means of the drive roller (14) and the pinch roller (34), and the recording medium (10) is carried onto the drafting member (12) by the rotation of the drive roller (14). The recording head (22) reciprocatingly shifts in a direction perpendicular to the carrying direction of the recording medium (10) on the drafting position of the drafting member (12). The suction force is generated by the suction device (36) in a predetermined range of the drafting member and surrounding the drafting member (12), and the recording medium (10) is attracted to the drafting member (12). The unevenness guide unit (19) having the suction holes is formed on the drafting member (12), and the recording medium (10) is adsorbed to the unevenness guide unit (19) by means of the suction force of the suction device (36).

Abstract: A spindle head 28 is liftably supported on a transfer member 6 which is capable of moving in an XY axis direction to a table 4, and a spindle 32 is rotatably journalled on the spindle head 28. A pickup 54 is liftably journalled on the spindle head 28, and the pickup 54 is disposed at the lower end of a tool 46 near the tip of the tool 46 which is fixed detachably to the spindle 32. The relative lifting motion of the pickup 54, against the head 28, is detected by a sensor 70. Prior to the processing of the work, a distance D, between the lower end of the pickup 54 and the tip of the tool 46, is measured, and is stored in the controller. The head 28 descends, and when the pickup 54 abuts on the work, this abutting condition is detected by the sensor 70. The height of the tip of the tool 46 against the work 2 is detected by the foregoing detection.
