This invention provides a base material comprising a plastic-containing support and, on its surface, a hydrophilic layer comprising an ethylene glycol chain (an EG chain) composed of one or more ethylene glycol units, as well as a method for producing such base material. A polysiloxane-containing primer layer is provided on the support comprising a plastic material on its surface, and the EG chain is covalently bound to a polysiloxane side chain of the primer layer. Thus, a hydrophilic layer comprising the EG chain can be provided on the surface of the plastic-containing support.

Base material comprising hydrophilic layer

A laser machining machine having a laser oscillator and a machining head communicating with each other through a propagation path for controlling the length of the propagation path in response to the position of the machining head. The laser machining machine divides a machining area at given intervals, and then sets an optical path position responsive to the machining area. The machine further detects the position of the machining head and controls the optical path length in response to the set optical path position.

The control unit comprises a first display unit which, when an error occurs, displays a primary error message; an error information input unit by which an user inputs error information corresponding to the primary error message, a memory which stores the error information input using the error information input unit; and a second display unit which displays the error information.
