Description

[Detailed description of the invention] [Industrial application field] The present invention is an index used in a coordinate analyzer that manually moves a carrier along a table surface and counts and displays the amount of movement of the carrier in the XY coordinate axis direction. Regarding the board.

[Conventional technology]

The index plate used in this type of coordinate analyzer has a crosshair index formed on a transparent flat body, and the operator performs coordinate reading work by aligning the index with the point to be read. The above coordinate analyzer
When you use it as an XY plotter and want to mark a point at a desired XY coordinate point, use the specified position on the indicator plate as a mark, and while watching the display on the XY display section that displays the XY movement amount of the carrier, The mark position is moved to the point to be dotted, and at that position, a dot is dotted on the paper on the table with a writing instrument at the mark position.

[Problem that the invention attempts to solve]

In the case of the above-mentioned dotting work, since the writing instrument is in a free state with respect to the indicator board, it is difficult to align the writing instrument, and therefore, it is not possible to perform the dotting work by hand accurately and quickly. The present invention aims to eliminate the above defects.

[Means for solving problems]

The present invention is based on the XY coordinate plane of the carrier 2.
It consists of a transparent flat body that is attached to the carrier 2 of the coordinate analyzer that counts and displays the amount of movement in the coordinate axis direction, and the body 4 has an index 6 and a writing guide circumferential surface for regulating the position of the tip of the writing instrument. It is characterized by providing a writing instrument insertion hole 8 surrounded by 8a.

〔Example〕

The configuration of the present invention will be described in detail below based on embodiments shown in the accompanying drawings.

In FIG. 1, 10 is a table, 12 is a horizontal rail, and a vertical rail 14 is movably connected to this via a horizontal cursor. Said vertical rail 1
The tail end of the table 1 is connected to the table 1 through the tail roller 18.
It is supported on the 0 surface so that it can run freely. A vertical cursor 16 is movably attached to the vertical rail 14, and a carrier 2 consisting of a head is connected to the vertical cursor 16 via a hinge connecting member. An indicator plate 4' is removably attached to the attachment plate of the carrier 2. 20 is a display section provided on the carrier 2; 22 is a keyboard provided on the carrier 2; 24
26 is an X pulse encoder, 26 is a Y pulse encoder, and 28 is a computer.

Next, the configuration of the index plate 4' will be explained. The indicator plate 4' consists of a transparent flat body 4, on which a crosshair indicator 6 is formed. Reference numeral 8 denotes a writing instrument insertion hole for inserting the tip 32 of the writing instrument 30, which is transparently provided at a proper place in the main body 4, and a tapered surface is formed on the upper part of the guide peripheral surface 8a that forms the periphery of this hole 8. . The diameter of the hole 8 is set to exactly match the diameter of the tip 32 of a standard type commercially available writing instrument. As shown in FIG. 3, a plurality of writing instrument insertion holes 8 are provided according to the diameter of the tip for each type of writing instrument such as a hollow pen, sharp pencil, ballpoint pen, etc. A display 36 indicating the diameter may be attached and provided transparently on the main body 4.

[Effect]

Next, the operation of this embodiment will be explained. carrier 2
If you hold it in your hand and apply force in any direction parallel to the table 10, the horizontal cursor will move to the horizontal rail 1.
2, the vertical cursor 16 moves along the vertical rail 14, and the vertical cursor 16 moves along the vertical rail 14.
can be moved to a desired position on the table 10. The X movement amount of the horizontal cursor with respect to the origin and the Y movement amount of the vertical cursor 16 with respect to the origin along the vertical rail 14 are displayed on the display unit 20 in decimal notation. By aligning the center of the index 6 with the point to be read on the drawing of the table 10 and pressing the record switch on the keyboard 22 at that position, the index 6
The XY coordinate values of the center point of can be stored in the computer's storage device. paper on table 10
When it is desired to place a dot at a predetermined XY coordinate position with respect to the XY origin, the hole 8 of the index plate 4 is aligned with the origin mark on the paper, and in this state the counter of the calculator 28 is reset to zero. Next, the carrier 2 is moved while viewing the display on the display section 20, and when the display on the display section 20 reaches a predetermined value, the carrier 2 is stopped. Next, as shown in FIG. 2, the tip 3 of the writing instrument 30
2 into the hole 8 and make a dot on the paper. At this time, since the tip 32 of the writing instrument 30 is regulated by the guide circumferential surface 8a, the tip 32 of the writing instrument 30 is
2 and the index plate 4 do not change.

〔effect〕

As mentioned above, the present invention has a writing instrument insertion hole that fits the tip of the writing instrument on the indicator plate, so the indicator plate can be used not only for reading coordinates but also for dotting. This allows you to set the tip of the writing instrument in the correct position.
There is an effect that the dotting work can be performed efficiently and accurately.

Claims (1)

[Scope of utility model registration request] It consists of a transparent flat body that is attached to the carrier 2 of the coordinate analyzer that counts and displays the amount of movement of the carrier 2 in the XY coordinate axis direction along the XY coordinate plane, and the body 4 is equipped with an index 6 and a writing instrument. An index plate characterized in that a writing instrument insertion hole 8 is provided surrounded by a writing guide peripheral surface 8a that matches the diameter of the tip of the writing instrument for regulating the position of the tip of the writing instrument.
