Abstract

PURPOSE:To prevent the exhausting of ink in a drawing pen by providing a drawing accumulated time recorder to write drawing accumulated time in a recorder and a drawing accumulated time displayer to display drawing accumulated time. CONSTITUTION:In a drawing accumulated time composer 10, accumulated drawing times hitherto of a drawing pen 5, which are magnetically recorded in a drawing accumulated time recording face 16 attached to the pen 5 are read out through a reading head 11. Drawing time from a drawing time sensor 8 is updated in terms of drawing accumulated time. In a drawing accumulated time recorder 12, the drawing accumulated time updated in the composer 10 is written in the recording face 16 through a writing head 13. Also, in a drawing accumulated time displayer 14, drawing accumulated times from the recorder 12 are displayed in a displayer 15 and at the same time a plotter control signal 18 is sent out to the plotter controller 20 to cancel command by a plotter control signal 19 for permitting the processing the next data. The reprocessing of drawing due to exhausted ink in the drawing pen can thus be avoided.

Description

[Detailed description of the invention] [Industrial application field] TECHNICAL FIELD The present invention relates to a ruru plotter, which is a device for plotting.

[Conventional technology]

FIG. 2 is a block diagram of a conventional plotter.

In the figure, plotter control section a1 is data control section 2.
The receiving drawing data is sent to the head control section 3 by a head control signal 17, which causes the head 6t to move back and forth and left and right, and also sends a pen control signal 7 to the pen control section 4, which causes the drawing pen 5t attached to the head 6 to move up and down. , was drawing.

[Problem that the invention seeks to solve]

The above-mentioned conventional plotter does not have a function to judge the ink flow condition of the drawing pen, so if the drawing pen has a structure that makes it impossible to judge the ink flow state of the drawing pen, there are the following disadvantages. 0 ■ Since the amount of ink remaining in the drawing pen was unknown, it was impossible to predict the remaining usable time, and when drawing for a long time, there was a possibility of running out of ink in the middle. 0 ■ Drawing Peso Because the amount of ink in the pen is unknown, it is not possible to predict the remaining iT function time, and there are cases where the drawing pen is discarded even though it is still possible to draw for a sufficiently long time. It was not used effectively.

[Problem t-Means for solving]

The plotter of the present invention includes a plotting time detection section that determines the plotting time of the plotting pen, and a plotter that reads the plotting time from the recording section provided on the plotting pen. A cumulative drawing time synthesis section that updates the cumulative drawing time by adding the drawing time obtained by the drawing time detection section; and the drawing lI & accumulation time opening time record recording section updated by the cumulative drawing time synthesis section. The image forming apparatus includes a drawing cumulative time recording section for writing data into the drawing area, and a drawing cumulative time display section for displaying the drawing cumulative time.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a plan view showing one embodiment of the present invention.

The structure of the plotter of the present invention is the conventional plotter shown in FIG. Reading head 11, cumulative drawing time recording section 1
2. A writing head 13, a cumulative drawing time display section 14, a display 15, and a cumulative drawing time recording section 16 are added;
A plotter control section 20 is provided instead of the plotter control section 10. The plotter control section 20 receives drawing data from the data control section 2 and sends a head control signal 17 and a pen control signal 7 to the head control section 3 and pen control section 4, respectively, to perform drawing processing.

The drawing time detection s8 uses the pen control signal 7 and the timer 9 to detect the drawing time (the total time from the pen lowering request signal to the pen rising request signal) and sends the drawing time to the cumulative drawing synthesis unit 10. .

Also, when instructed by an operator, etc., the drawing time is detected.
8 is the plotter control signal 1 to the plotter system #J section 20
9, instructs the operator 9 not to process the next data, moves the drawing pen 5 upward via the pen 1tjlJ control section 4, and outputs the cumulative drawing time synthesis section lO1 and the cumulative drawing time recording section 12.
The cumulative drawing time display unit 14 is caused to perform the following operations.

The cumulative drawing time synthesis unit 10 reads the accumulated drawing time of the drawing pen 5, which is magnetically recorded on the cumulative drawing time recording surface 16 attached to the drawing pen 5, through the RAD 11, and prints the drawing. The drawing time from the time detection unit 8 is added to update the cumulative drawing time. The cumulative drawing time recording section 12 records the cumulative drawing time updated by the cumulative drawing time synthesis section 10 into the cumulative drawing time recording surface 16 through the sinking head 13.The cumulative drawing time display section 14 records the cumulative drawing time. Display 1 the cumulative drawing time from s12
At the same time, the plotter control signal 18 is sent to the plotter control g20 to cancel the command by the plotter control @ signal 19, and to enable processing of the next data. After using the plotter control signal 5ieff, the plotter control $20 reads the next drawing data from the data control unit 2 and processes it. By recording and displaying the time, if you measure the lifespan of the drawing pen in advance, you can easily know how much time the drawing pen has left to use.

This has the advantage that it is possible to prevent the drawing process from being redrawn due to the drawing pen running out of ink, and to make effective use of the drawing pen.
