Then, use the aperture 6 and the aperture 7 to expose the desired location on the unexposed film to create the exposure shape shown in Figure 4, and then use the aperture 8 to move the remaining part as shown in Figure 5 to create the trajectory section. This had the disadvantage that the amount of information required for drawing was large and complicated.

The input buffer circuit 17 is a first-in, first-out buffer storage circuit that temporarily stores data from the data processing section 11 to cope with the speed difference between the data processing section 11 and the expansion processing circuit 18. The registered shape memory circuit 19 stores an arbitrary predetermined shape corresponding to an aperture before the expansion process,
This is a circuit for reference during expansion processing. The expansion processing circuit 18 receives data from the input buffer circuit 17 and the continuous data buffer circuit 21, determines its shape, and in the case of data with a simple shape such as a triangle, rectangle, or parallelogram, calculates the data at the raster position to be expanded. Find the pattern generation position in the main scanning direction and store it in the developed figure storage circuit 20 as a one-dimensional pattern.If the data has an arbitrary shape that cannot be determined by calculation, register the pattern in the main scanning direction at the raster position to be developed. The shape memory circuit 19 refers to the pattern generation position and stores it in the developed figure memory circuit 20 as a one-dimensional pattern. In addition, the input data that has been expanded is
It is determined whether the data is necessary for subsequent raster expansion processing and the necessary data is sent to the continuous data buffer circuit 21. The expansion processing circuit 18 performs these processes as raster 1.
This is a circuit that is executed repeatedly for each duty. The continuous data buffer circuit 21 is a first-in, first-out storage circuit that receives data from the expansion processing circuit 18 and sends out data every time the expansion processing circuit 18 requests.
The expanded figure storage circuit 20 is a circuit that stores information for one raster in the form of a bit string, and stores the one-dimensional pattern expanded by the expansion processing circuit 18 until all expansion processing for one raster is completed. After completion, this circuit transmits one raster's worth of patterns to the output buffer circuit 22. The output buffer circuit 22 is a first-in, first-out storage circuit that receives data from the expanded figure storage circuit 20 and transmits the data to the mechanical optical system drive section 15 for each data request.

The instruction discrimination circuit 23 receives expanded data from the expansion processing circuit 18 and determines whether this data is generated by a true instruction or a false instruction, and determines whether the data generated by a true instruction is true. The data generated by the false command is written to the graphic buffer 25 for false commands. The false instruction priority output circuit 26 outputs the true instruction graphic buffer 24 after completing the expansion process for one raster.
This circuit simultaneously reads the same position of the false instruction graphic buffer 25 and removes the false instruction graphic from the true instruction graphic and transmits it to the output buffer circuit 22.

FIG. 3 is a detailed block diagram of the developed figure storage circuit 20 in the case of FIG. The priority classification circuit 27 receives expanded data from the expansion processing circuit 18, determines the priority of this data, and writes data into buffers 28 for each priority separately into data based on true instructions and data based on false instructions. Priority output circuit 29
After the expansion process for one raster is completed, the buffer circuit reads the same position of the buffer 28 for each priority, adopts the data with the highest priority, and outputs the exposure data if it is data according to a true command. If the data is due to a false command or there is no command, non-exposure data is transmitted to the output buffer circuit 22.

is used to transmit the signal to the optical modulator 31. Optical modulator 31
The light is switched between brightness and darkness using an electrical signal from the mechanical optical system drive unit 15 shown in FIG. 6, and is transmitted to the optical deflector 32. The optical deflector 32 slightly changes the direction of the laser beam and transmits it to the beam expander 34 so as to cancel out the position error of the laser beam that is expected to occur due to the tilting of the surface of the rotating mirror 33. The beam expander 34 widens the beam diameter to narrow the laser beam onto the lower drawing table 35 and transmits it to the rotating mirror 33. The rotating mirror 33 is an octagonal prism mirror rotated by a motor, and scans the laser beam and transmits it to the condensing f-θ lens 36. Focusing f-θ
The lens 36 narrows the laser beam onto the film 37 on the drawing table 35 and focuses the laser scanning light moving at a constant angular velocity onto the film 37 on the drawing table 35 so that it moves at a constant velocity. The drawing table 35 is a support for the film 37 that is moved at a constant speed by a servo motor 38, and is a drawing mechanism that draws a two-dimensional pattern on the film 37 in conjunction with the main scanning of the laser beam by the rotating mirror 33.

A storage unit that stores the shape of a planar figure, a means for generating a pattern of the planar figure by referring to the storage unit according to a logically true drawing command, and a logically false drawing command. Means for generating an inverted pattern of the planar figure by referring to the storage unit according to a command, and inversion of the planar figure by the logically false drawing margin in that the true and false drawing commands overlap. 1. A numerically controlled drawing device comprising: means for selecting a pattern generated and selected; and means for exposing an unexposed film using the generated and selected pattern to draw a figure. 2. A storage unit that stores the shape of a planar figure; a means for generating a pattern of the planar figure by referring to the storage unit according to a logically true drawing command; means for generating an inverted pattern of the planar figure with reference; 2.
In the point where the above-mentioned drawing commands overlap, means for selecting the pattern according to the drawing command having the highest priority at that time according to the priority set in advance for each of the drawing commands;
A numerically controlled drawing device characterized by comprising means for drawing a figure by exposing an unexposed film according to the selected pattern.
