[0002]

2. Description of the Related Art In recent years, new archeological sites have been discovered one after another at civil engineering sites and construction sites, and numerous haniwa, earthenware, bronzeware, and the like have been excavated. These excavated items are organized by copying the plan view, front view, side view, back view, and bottom view in one-to-one size according to the parallel projection method based on the orthogonal projection method. To explain the principle of the perpendicular projection with reference to FIG. 5, put projection plane PL ₁ above article D ₀ of interest. Then, drawing a parallel linear B ₁ .about.B ₈ mutually perpendicular to the projection plane PL ₁ from each point of the contour of the article D _0, plan view D ₀₁ of the contour shape of the article D ₀ by connecting the intersection of the PL ₁ Is drawn.

The drawing method of the right side view is shown. Above the article D _1, front, placing the projection plane PL ₁ through PL ₃ by mutually orthogonal on the right side, drawing a straight line parallel to each other in the vertical from each point of the contour of the article D ₁ on the projection plane PL _1, PL ₁ Goods D ₁ by connecting the intersection with

Conventionally, the copying of an article by the above-described orthogonal projection method involves measuring a distance between various two points of an article using a ruler, measuring an angle between various three points, and using a ruler and a compass. , Using a protractor or the like to draw on a drafting paper with a writing implement. Therefore, it took a lot of time to copy one article. Regarding this problem, it is conceivable to improve the work efficiency by taking a picture of the article, stretching it at an appropriate magnification, and tracing it. However, the picture is equivalent to the central projection method, and as shown in FIG. D
₀ from the point of view VP drawing a straight line connecting the respective points and VP contour when viewed through the projection plane PL _7, a line connecting the intersection of the projection plane PL _7. Therefore, since the scale is in the projected image r'of the projected image q'and bottom side R of one side Q of the upper surface U of the article D ₀ are different, when the entire projected image is stretched at a magnification to be Q = q', R = R ', and the actual length cannot be directly taken as in the parallel projection method (r
'Must be s).

In view of this problem, the present inventor has previously commercialized a copying apparatus capable of accurately and simply copying an article by the orthogonal projection method (see Japanese Patent Application Laid-Open No. 7-278322).
FIG. 9 is an external perspective view of the copying apparatus. 1 is a table, 2 is a TV receiver as an example of a display device placed on the table 1, 3 is a work table, and includes a frame 4 and a transparent top plate 5 horizontally arranged on the frame 4. Become.
Under the left half of the top plate 5 in FIG. 9, the article A to be copied is placed on the table 6, and on the approximately right half of the top plate 5 in FIG. (Not shown). At the upper right end of the frame 4 in FIG. 9, one end of an arm 8 for parallel movement is pivotally supported so as to be freely rotatable. In FIG. 9, the support member 10 extending in the left lateral direction and the support member 11 slightly extending in the right lateral direction in FIG. Bolted.

A TV camera 12 as an example of an image pickup device and a writing instrument 1 are provided near the distal ends of the support members 10 and 11, respectively.
3 is fixed vertically downward. As shown in FIG. 10, the support member 11 is provided with a holder 14 to which the writing instrument 13 can be attached and detached. This holder 14 supports the support member 1
A screw 15 screwed into 1 and an L-shaped pressing member 16 into which the screw 15 is loosely inserted. The screw 15 is loosened, and the writing implement 13 is sandwiched between the pressing member 16 and the supporting member 11,
The writing implement 13 can be easily mounted by tightening the screw 15 while adjusting the height of the tip of the writing implement 13 to substantially contact the paper 7. At this time, since the holding portion 9 of the arm 8 is placed on the top plate 5 and the weight of the distal end of the arm 8 is supported by the top plate 5, the paper 7 is not subjected to pen pressure and is not stained. Note that most of the weight of the arm 8 is supported by the frame 4 on the base end side of the arm 8, so that the parallel movement operation can be performed smoothly even if the holding portion 9 is placed on the top plate 5. If the screw 15 is loosened, the writing implement 13 can be replaced.

The arm 8 for parallel movement has the same mechanism as the drafter arm for drafting. The arm 8 is moved by holding the knob 17 or the tip of the writing implement 13 to move the TV camera. The writing instrument 12 and the writing instrument 13 can be integrally moved in a plane. By this parallel movement, the TV camera 12 and the writing instrument 13 each move in a plane parallel to the top plate 5.

The video output of the TV camera 12 is transmitted through a cable 18.
Is input to the TV receiver 2 through the TV camera 1
The image of the article A captured in 2 is displayed on the screen 19.
Center of the screen 20 of the cathode ray tube of the TV receiver 2 (screen 19
(Corresponding to the optical axis of the TV camera 12) is marked with a cross reference point mark 21. Since the magnification of the TV camera 12 is arbitrary, it may be set appropriately.

Next, the operation of the above-described copying apparatus will be described with reference to FIG. The article A to be copied is placed under the left half of the top 5 in a predetermined direction, and the paper 7 is attached to the right half of the top 5. When it is desired to draw a plan view of the outline shape of the article A by the orthogonal projection method, first, the user moves the tip of the writing implement 13 in a plane parallel to the top plate 5 and moves the reference point mark 2 on the screen 19.
1 is adjusted to the outline of the image of the article A, and then while the writing implement 13 is slightly depressed and the pen pressure is applied to the paper 7, the reference point mark 21 relatively moves along the outline of the article A in the image. The writing implement 13 is continuously moved together with the TV camera 12 to draw a line drawing (see FIGS. 11A and 11B).
At this time, the vertical optical axis C of the TV camera 12 is
In FIG. 5, the intersections between the optical axis C and the top plate 5 are equivalent to the perpendiculars B _{1 to} B ₄ vertically lowered from the contour of the article D ₀ to the projection plane PL _1. Become. Since the writing implement 13 moves in the same manner as the TV camera 12, the line drawing becomes a right angle projection image of the outline of the article A, and the outline shape of the article A is reproduced in a one-to-one size.

As described above, according to the copying apparatus shown in FIG. 9, the operator operates the TV camera 12 and the writing implement 13 so that the reference point mark 21 on the video screen relatively moves along the contour shape of the article A. By simply performing a simple operation of performing a parallel translation on a plane by integrating the two, the copying of an article by the orthogonal projection method becomes possible, and the work efficiency is dramatically improved. In addition, even if the worker does not hold down the tip of the writing implement 13 and presses down, when the paper 7 is under writing pressure, the user holds the knob 17 at the tip of the arm 8 and the TV camera 12 and the writing implement. 13 may be moved in parallel.
