Problems solved by technology

[0009] In such a conventional printed circuit board exposure apparatus, since the drawing process is completed and the next drawing process is started, the fixing mechanism of the drawing table is released, and the recording medium is respectively fixed by the loader and the unloader, and the sliding mechanism is used to fix the recording medium. Move the drawing table to the side of the loader, use the fixing mechanism of the drawing table to fix the recording medium on the drawing surface of the drawing table, then release the pair of pinch rollers of the loader, and pass the A pair of pull-out rollers draws out the recording medium and makes it sag, and does not move to the next drawing operation until the above operations are completed, so the waiting time other than the exposure processing time is long, so there is a problem of low productivity

Embodiment Construction

[0037] Below, refer to Figure 1- Figure 9 , an embodiment of the drawing device of the present invention will be described.

[0038] The drawing device according to the embodiment of the present invention is configured as an exposure device automatically controlled by a control unit, and moves a flexible printed wiring board material, which is a flexible recording medium formed of a long strip-shaped sheet, in the main scanning direction, and simultaneously Using the exposure head, a plurality of light beams emitted from the light source side are spatially modulated based on a modulation signal generated by the control unit from image data, and irradiated onto the flexible printed wiring board material to perform exposure processing.

[0039] As shown in FIG. 1 , in this drawing device, an exposure processing unit 12 is arranged at the central portion of a chassis 10, and an unexposed recording medium supply unit is arranged at one side of the exposure processing unit 12 (tow...

Abstract

The invention provides a drawing apparatus, which can continuously expose a long strip of flexible recording medium and can expose a plurality of flexible recording medium in a short time, thereby shortening the latency time and the raising productivity. Between at least two rollers (30, 32), the long strip of flexible recording medium (28) is arranged, and can be conveyed to certain conveying direction. Then, a tension setting mechanism (68) is used for definitely maintaining part of the tension of the long strip of flexible recording medium which is arranged between the two rollers (30, 32) through, so as to pull the long strip of flexible recording medium in a tabulate way; a drawing unit (48) is used for drawing the long strip of flexible recording medium according to two-dimensional graphics, therefore, the invention can raise the productivity because of continuous exposure treatment.

Description

technical field [0001] The present invention relates to a drawing device for drawing by a mechanism, etc., which uses a spatial light modulation element (two-dimensional light modulator) or the like provided on an exposure head to irradiate a long flexible recording medium based on graphic data. The modulated light beam is exposed according to the prescribed pattern. Background technique [0002] Commonly used drawing devices include scanning printed circuit board exposure devices, laser photoplotters, laser printers, and other exposure devices that scan a recording medium with a light beam to draw a desired image thereon. [0003] In such an exposure apparatus, for example, in the case of a printed circuit board exposure apparatus, a laser beam is scanned on a recording medium, that is, a substrate material for a printed wiring board, to perform drawing. The substrate material for a printed wiring board used here is formed by forming a conductive thin film on an insulating...
