Multi-purpose apparatus for the imaging of printed wired boards

A multi-purpose apparatus for the manual and automatic imaging of Printed Wired Boards, comprising:

• a base frame formed by a group of rectangular tubes and a channel, rigidly attached and parallel to each other differently to suit the various applications of the apparatus and connected:
• on one side for a manual or automatic operation in processing one panel's breadth;
• in the middle, for manual or automatic operations to process two different or equal panel's breadth;
• one group on each side, attached to each other by a conveyor, to process automatically and in line two panels at the same time;
• one tube of said group being somewhat shorter and also rectangular, is connected transversally to two more tubes of the same height, which in turn are connected to a third one also transversally;
• attached to said rectangular member tube, on its surface, at least two metallic die strips uniformly interspaced and extending to the whole length of said tube, have rows of die holes used as punch dies to perforate photomasks before exposure and to align a punching pin, sliding through at least two L-shaped punch block members clamped on said holes by a bolt and thumb screw going through it, an L-shaped member, likewise said punch block members, clamped to the said holes, having a sliding member, in its grooved top surface which has its back end shaped like a fork and attached to its front end, an indexing spring-loaded pin;
• and a glass resting on said transversal tube members having the same height of said prior die strips.
