Abstract

PURPOSE:To reduce the number of installed figure input devices by constituting the titled system in such a way that plural figure processors share the same figure input device and receive figure information. CONSTITUTION:First, a machining figure is read to a figure input device 1. The machining figure read to an arbitrary figure processor 2 is transmitted as a machining figure information through a data communication network 4. Here, when the data communication network 4 is constituted of a two-way signal cable, the figure input device 1 transmits the figure information to the figure processor 2, and simultaneously the transmission between the figure input devices 1 and that from the arbitrary figure processor 2 to the figure input device 1 become possible. The figure processor 2 where machining figure information is inputted executes the arithmetic operation of the machining figure information to the information which a machining device and drawing device require.

Description

Detailed Description of the Invention [Technical Field of the Invention] The present invention relates to an automatic drawing creation device (hereinafter referred to as a CAD device), an automatic manufacturing device (hereinafter referred to as a CAM device), and a numerical control device (hereinafter referred to as an NC device).
This invention relates to improvements to drawing input systems for inputting character and graphic information such as devices.

[Prior Art] A conventional device of this type is shown in FIG. 2, in which (1) is a drawing input device into which characters, drawings, etc. are input from the outside. (2) The above drawing input device (1
These are various drawing processing devices that receive drawing information from () and perform processing such as calculation and analysis on the drawing information, including CAD devices,
These include CAM devices, NG devices, etc. (3) is a signal cable for transmitting drawing information between the drawing input device (1) and the drawing processing device (2).

Based on the above configuration, the operation of the conventional device will be explained. First, the drawing input device (1) reads a machining diagram, and the drawing input device (1) converts the read machining diagram into an electrical signal as machining diagram information. Next, the processing drawing information converted to this electrical signal is transferred to the signal cable (
3), the data is transmitted to the drawing processing devices M(2) corresponding to the drawing input device W(1), and processing such as calculation and analysis is performed in the drawing processing devices (2).

In the conventional system described above, a drawing input device is provided as a dedicated input device for each drawing processing device, so when a plurality of drawing processing devices such as a CAII device, a CAM device, an NG device, etc. are provided, A number of drawing input devices greater than the number of these plurality of drawing processing devices are required. Furthermore, since it is necessary to provide the drawing input devices redundantly, the overall system configuration is complicated, the installation area is large, and the price is high.

[Summary of the Invention] The present invention has been made in view of the above points, and has a configuration in which a plurality of drawing processing devices share the same drawing input device to receive drawing information, thereby improving the installation of the drawing input device. This paper proposes a drawing input system that can reduce the number of units, simplify the entire system, reduce the installation area, and reduce the cost.

[Embodiment of the Invention] Hereinafter, an embodiment of the present invention will be described based on FIG. 1, in which the same parts as those of the conventional device shown in FIG. 2 are given the same reference numerals. FIG. 1 shows an overall circuit block diagram of this embodiment, and in the same figure, the drawing input system according to this embodiment is based on a drawing input device (1) and drawing information inputted by the drawing input device (1). Multiple drawing processing devices (
2) and (2) are connected by a bidirectional or unidirectional data communication network (4), and the plurality of drawing processing devices (
2).

(2) share the drawing input device (1) to receive drawing information.

The above-mentioned drawing input device (1) is for inputting line diagrams of drawings, etc.
Consists of RAND tablets, etc.

Next, the operation of this embodiment based on the above configuration will be explained. First, the drawing input device (1) reads a machining drawing as in the case of the conventional system, and an arbitrary drawing processing device (2) reads the machining drawing.
)'''The read t'''''machine machining 1 drawing j is transmitted as machining drawing information via a data communication network (4).Here, the data communication network (4) is connected to a bidirectional signal cable. If the drawing input device (1) is configured as (when multiple units are installed), and any drawing processing device (2), (2) to drawing input device (1
) is also possible.

The drawing processing device (2) into which the above processing drawing information is input,
Processing device 1 Performs processing such as calculation and analysis of information necessary for processing or drawing by a drawing device or the like (not shown).

In addition, if transmission is possible between the drawing input device (1) and the drawing processing device (2), the processing drawing information can be input in an interactive format according to the request of the drawing processing device (2). This makes it possible to create and input more appropriate processing drawing information.

Further, in the above embodiment, the drawing input device (1) was explained for inputting a line diagram of one drawing, but it can also be constituted by an input device for character and graphic information such as a facsimile, and further, In addition to two-dimensional descriptions such as diagrams, it can be configured with a hologram or the like that can also input three-dimensional solid information.

Furthermore, the data communication network (0) may be for digital signals or for analog signals, such as a telephone line.

[Effects of the Invention] As explained below, the present invention has a configuration in which a plurality of drawing processing devices share the same drawing input device to receive drawing information, thereby reducing the number of drawing input devices installed. This has the effect of simplifying the entire system, reducing the installation area, and reducing the cost.
