, press the continuous feed switch in the direction of the +X coordinate axis.
SW ₁ and a step feed switch SW ₂ are provided. Switches corresponding to the switches SW ₁ and SW ₂ are also provided in the -X, +Y, and -Y coordinate axis directions, respectively. Conventionally, when moving the head 6 of a drafting machine to a desired position by manual operation of a switch, first the X pulse motors 8 and 10 and the Y pulse motor 12 are driven by a continuous feed switch.
The head 6 is moved close to the desired position and then the step feed switch is used to move the head 6 to a more accurate position. At this time, the head 6 moves by only one pulse each time the step feed switch is pressed, and it is necessary to press the switch several dozen to several dozen times to bring the head 6 to the desired position. Move the X cursor 14 as shown in FIG.
When moving from point a to point b in the direction of the +X coordinate axis, when continuous feed switch SW ₁ is pressed, the pulse 16 is transmitted from the oscillation circuit 18 to the drawing machine drive circuit 20 as shown in FIGS. It is continuously supplied to the pulse motor 8, and the X cursor 14 reaches point c. Next, each time the step feed switch SW ₂ is pressed, one pulse 24 is sent from the differentiating circuit 22 to the drive circuit 20.
By repeating this multiple times, the X cursor 14 reaches point b.

のである。 As is clear from the above description, there is a drawback in that it takes time to move the writing instrument in the head 6 to a desired position on the mounting table 24, resulting in poor operability. Therefore, the object of the present invention is to eliminate the above-mentioned defect by automatically changing the supply of pulses to the pulse motor from step feed to continuous feed when the step feed switch is pressed for a certain period of time or more. .

テツプ送りが可能である。 When the switch 30 is turned ON, a signal of "1" is applied to the oscillation circuit 32, the oscillation circuit 32 is operated, and the sending pulse 46 is continuously supplied to the drive circuit 42, and the pulse 46 is transmitted from the circuit 42. It is supplied to the X pulse motor 8. Next, switch 44
When turned ON, a signal of "1" is input to the differentiating circuit 34, and the differentiating circuit 34 outputs the sending pulse 48. At the same time, the delay circuit 36 starts operating and after time td, one input terminal of the AND circuit 38 becomes "1". At this time, if switch 44 is ON,
The input terminals of the AND circuit 38 become "1", "1",
AND circuit 38 outputs "1". This causes the oscillation circuit 40 to operate, and continuous sending pulses 50a, 50b, . . . are output from the circuit 40. Next, when the switch 44 is turned off, the output level of the AND circuit 38 becomes "0", the oscillation circuit 40 stops operating, and the pulse output ends. As shown in Figure 6,
If the delay time td of the delay circuit 36 is appropriately determined, conventional step feeding can be performed by repeatedly turning the switch 44 ON and OFF.

わかりやすくしている。 Generally, the amount of cursor feed per one pulse or one step of a drawing machine is from several microns to several tens of microns, so it is difficult to visually perceive the movement of the X cursor 14 due to the output pulses of the oscillation circuit 40 or the differentiating circuit 34. Therefore, when moving the head 6 to a desired position, it is difficult to know when to turn off the switch 44. Therefore, a buzzer, lamp, etc. driving circuit 52 is connected to the output line of the differentiating circuit 22 and the output line of the oscillation circuit 40, and the buzzer 52 is connected to the output line of the differentiating circuit 22 and the output line of the oscillation circuit 40.
