Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a panel for adsorbing and holding a recording sheet or the like by the action of static electricity, and more particularly to an electrostatic adsorbing panel with improved paper feeding operation.

(Prior Art) With recent advances in computer technology, plotters that automatically record calculation results and statistical samples in the form of graphs and graphs are widely used. When the plotter is used, the recording paper may be attracted to the recording pen by static electricity generated by friction between the recording paper and the recording pen. In order to prevent this, an electrostatic attraction panel that attracts and holds the recording sheet by the action of static electricity is usually used.

An example of this type of electrostatic adsorption panel is, for example, the actual open sho 61-
Some are disclosed in the specification and drawings of 37996.
FIG. 4 is a perspective view showing a main part of the electrostatic attraction panel of the prior art. In the figure, a net layer 102 is formed on the surface of the electrostatic adsorption panel 101. Also, electrostatic adsorption panel 1
An electrode and a dielectric (not shown) are provided at 01. When recording, first, a voltage is applied to the electrodes to generate static electricity on the surface of the dielectric. Next, a recording sheet (not shown) is placed on the net layer 102. Here, the air staying between the recording sheet and the electrostatic adsorption panel 101 escapes to the outside of the panel 101 through the mesh layer 101, so that the formation of air pockets is prevented in advance, and the recording sheet is kept in a stable state. Will be placed. Then, a recording pen (not shown) can be moved vertically and horizontally to obtain desired recording.

By the way, when the recording sheet is placed on the electrostatic adsorption panel for recording, the following is required. That is, the first
Secondly, when recording, the recording paper is attracted to the electrostatic adsorption panel in a stable state and properly held, and secondly, when the paper is fed after the recording is completed, static electricity is generated between the paper and the panel. That is, the electrostatic attraction force acting during the period is deactivated as soon as possible without staying in the period. In the electrostatic attraction panel described above, since the net layer 102 is provided, a tentative effect is obtained with respect to the first point, that is, the recording sheet is attracted in a stable state. .

(Problems to be solved by the invention) However, in the case of the conventional electrostatic adsorption panel of this type, as for the electrostatic discharge after the end of recording, that is, after the adsorption is stopped, the discharge to the air that is naturally performed is performed. It depends on everything. For this reason, since the static electricity stays for a long time, the desorption of the electrostatic attraction force is delayed, and the releasability of the recording paper from the electrostatic attraction panel is poor. This causes an inconvenience that the paper feeding operation is not smoothly performed immediately after the suction is stopped.

In view of the above-mentioned circumstances, the present invention has been made to solve the problems of the prior art, and its purpose is to:
To provide an electrostatic adsorption panel that does not impair the stable adsorption of a sheet to the panel during recording and that can smoothly and promptly feed the sheet after recording is completed. is there.

(Means for Solving Problems) In order to solve the above problems and achieve the object, the present invention is characterized in that the following technical means are adopted and combined. That is, the conductive member is arranged in a mesh shape on the surface of the electrostatic adsorption panel, and the conductive member is further arranged in a frame shape on the outer peripheral portion thereof. The conductive member is grounded. This conductive member is made of conductive paint, for example,
It is printed on the panel surface.

(Operation) In this electrostatic adsorption panel of the present invention, static electricity generated by friction between the dielectric and the paper after the recording is completed is transmitted through the mesh-shaped conductive member and the frame-shaped conductive member arranged on the outer periphery thereof. Let it escape to the ground. As a result, the accumulation of static electricity is prevented and the paper is smoothly fed. Further, during recording, the sheet is adsorbed by the portion (dielectric) that is not covered by the mesh-shaped conductive member, so that the sheet can be fixed in a stable state.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic front view of an electrostatic attraction panel 1 according to an embodiment of the present invention. In the figure, 2 and 3 are conductive patterns (conductive members), 4 is a ground wire, and 5 is a dielectric layer (dielectric).
The conductive pattern 2 is formed, for example, by printing a conductive paint on the surface of the dielectric layer 5 in a mesh pattern. The conductive pattern 2 has a pattern width of about 1 m as shown in FIG.
Experiments have shown that forming m and pitches (spacings) of approximately 7 mm is effective in adsorbing paper and releasing static electricity. Further, the thickness d of the conductive pattern 2 can be formed by a press or the like so that there is almost no step difference so that the force for adsorbing the paper during recording does not decrease. The conductive pattern 3 is also made of conductive paint, for example, and is printed integrally on the outer peripheral portion of the conductive pattern 2 on the surface of the panel.
In this case, the conductive pattern 3 is arranged outside the drawing (recording) range. A ground wire 4 is connected to the conductive pattern 3, and static electricity accumulated immediately after the end of recording can be discharged to a casing (not shown) through the ground wire 4. This accelerates the deenergization of the electrostatic attraction force. The dielectric layer 5 is exposed between the conductive patterns 2 arranged in a mesh. During recording, the dielectric layer 5 is charged and the paper is adsorbed and held in a stable state.

FIG. 3 shows a schematic configuration diagram of the recorder 6 in which the panel 1 is used. The same members as those in FIG. 1 are denoted by the same reference numerals, and the description thereof will be omitted. In the figure, 7 is a recording paper, 8 is a recording pen, and 9
Is a cutter, 10 is a paper driving mechanism, 11 is an insulating layer, 12 is an electrode, and 13 is an electrode. The state shown in FIG. 3 shows a continuous recording state using long paper.

When the cut paper is used, the cut paper is placed on the surface of the electrostatic attraction panel which is the recording surface, a voltage is applied to the electrode 13, and the dielectric layer 5 between the meshes attracts and fixes the cut paper. After the recording is completed, the static electricity remaining between the recording paper and the surface of the panel 1 is discharged to the ground through the conductive patterns 2 and 3. For this reason, since static electricity does not stay, the manual peeling of the recording paper becomes easy.

On the other hand, when using a long paper, for example, the recording paper 7 formed in a roll shape is pulled out by the recording paper drive mechanism 10 for each unit recording length, and recording is performed. When the recording is completed, the recording paper 2 is cut by the cutter 9. The use of the long paper will be further described as follows.

First, the unrecorded recording paper 7 is pulled out by the paper drive mechanism 10 by the unit recording length, and is fed to the recording surface, that is, the surface of the electrostatic adsorption panel 1. At this time, on this recording paper 7,
The electrostatic attraction is not performed, and the tension is adjusted so that a predetermined tension is applied between the paper driving mechanism 10 and the recording paper supply unit, and the wrinkles and the like of the recording 7 on the recording surface are removed. Alternatively, the recording paper 7 may be fixed by applying a voltage to the dielectric layer 5. Next, the recording pen 8 is moved vertically and horizontally to obtain a desired recording. When this recording is completed, the recording paper 7 having the unit recording length for the next recording is pulled out. Then, the recording paper portion having the unit recording length, which has already been recorded, is cut by the cutter 9, and this series of operations is completed. The static electricity generated by the friction between the recording paper 7 and the panel surface is the conductive pattern 2 and the conductive pattern 3.
Is discharged to the ground via the, and the discharge time constant becomes small. For this reason, static electricity does not stay, and the paper is fed smoothly.

In this embodiment, the case where the electrostatic attraction panel is applied to the recorder has been described, but it goes without saying that the present invention is not limited to this.

(Effect of the Invention) As described above, according to the present invention, the conductive member is arranged in a mesh shape on the dielectric formed on the surface, and the conductive member is arranged in a frame shape on the outer peripheral portion of the conductive member. In addition, since the conductive member is grounded, the paper is not sucked in a stable state on the panel during recording, and the paper is smoothly and quickly fed after the recording is completed. The unique effect of being able to do is brought about.
