Description

DETAILED DESCRIPTION OF THE INVENTION (1) Industrial Application Field The present invention relates to a recording device such as an automatic drawing machine and an X, Y recorder.

(2) Prior Art As shown in FIG. 7 as a recording apparatus of this type, a recording pen 125 is movably provided along the upper surface of a recording panel 102 on which recording sheets 123 and 124 are mounted. Things are known. Reference numeral 126 is a drive unit for the pen 125.

(3), Problems to be Solved by the Invention By the way, in the above recording apparatus, the recording panel 102 is fixedly provided and is not structured to move up and down. As shown, in the case of the thin recording paper 123, the panel 102 can be mounted by mounting it as an electrostatic attraction plate, but in the case of the thick recording paper 124 as shown in FIG. Etc. must be attached with 127, the installation work is troublesome, and the recording pen
There is a problem in that a mechanism for lifting the 125 upward by the thickness thereof is required, the structure around the pen 125 and the driving unit 126 becomes complicated, and the recording is adversely affected.

Therefore, an object of the present invention is to provide a recording apparatus which can be easily attached to a thick recording sheet as well as a thin recording sheet without lifting a pen or the like, and which does not cause a recording defect.

(4) Means for Solving Problems In order to achieve the above-mentioned object, the present invention provides a recording device as described above, wherein a recording panel is provided movably downward with respect to a recording pen by a predetermined distance. , The upper position of the recording panel, which is closer to the recording pen, is positioned, and when the recording panel is in the lower position and a thick recording sheet is attached, a fixed pressing plate that presses one side edge of the recording sheet is used. It is provided on a substrate for positioning the lower position of the panel, and this substrate is provided with a spring for constantly biasing the recording panel upward so as to abut the fixed pressing plate. It is characterized in that a movable pressing plate for pressing is provided movably so as to come into contact with and separate from the fixed pressing plate.

(5), To attach thick recording paper, press down the recording panel against the urging force of the spring, and then press the paper on the panel with an edge, for example, by a fixed pressing plate. Position it and place it. Thereafter, the pushing down is released, and by this release, the movable holding plate is positioned to the other side edge portion of the sheet on the panel that is lifted upward, and the other side edge portion is held down. As a result, one side edge of the thick recording paper is pressed by the fixed pressing plate and the other side edge is pressed by the movable pressing plate.
It will be attached to the top of the panel.

(6), Embodiment 1 In FIGS. 1 to 3, reference numeral 1 denotes a substrate, on which a recording panel 2 composed of an electrostatic attraction plate is provided at the same height as the substrate 1 along the upper and lower edges thereof. The frame pieces 3 and 4 are provided so as to be vertically movable within the range of the height. Frame piece 3,
4 is provided over almost the entire length from one side edge to the other side edge of the substrate 1, and an upper position of the panel 2 is positioned on the upper surface of the substrate 1, and the panel 2 is in the lower position to record a thick material described later. When the paper is attached, fixed pressing plates 5 and 6 for pressing the upper and lower edges of the paper are fixed by screws. A fixed pressing plate 7 for pressing the one side edge portion of the paper is bridged between the fixed pressing plates 5 and 6 near the other edges of the frame pieces 3 and 4, and fixed by screws or the like. Reference numeral 8 denotes an engaging groove formed at a downward position of the pressing plate 6 in FIG. 1. The frame piece 4 side of the groove 8 has an inwardly expanding tapered groove portion 8a and a frame piece 4a. The opposite side is formed with an inverted U-shaped groove portion 8a. Further, an engaging groove 10 is formed on the outer surface of the frame piece 3 to which the pressing plate 5 is fixed.

A movable pressing plate 12 for pressing the other edge portion of the paper is provided between the engaging concave grooves 8 and 10 so as to be movable in contact with and away from the pressing plate 7. As shown in FIGS. 4 (A) and 4 (B), the movable holding plate 12 has an engaging projection 15 which is engaged with the engaging groove 8 on the lower surface of one end of the holding plate main body 13. One end side of the main body 13 is formed in a taper portion 15a slidably fitted in the tapered groove portion 8a, and the opposite side thereof is formed in a protrusion 15b slidably fitted in the U-shaped groove portion 8b. Further, one end of the main body 13 is bent downward inward to form an engaging portion 16 which is engaged with the engaging groove 10. Reference numeral 17 denotes a paper pressing portion projectingly provided on the lower surface of the intermediate portion in the length direction of the main body 13, and 18 denotes a recess provided to form this pressing portion 17.

Reference numeral 20 is a coil spring that constantly urges the panel 2 upwards. A plurality of springs are provided on a support plate 21 provided below the substrate 1, for example, one for each of the front, rear, left and right in order to uniformly urge the panel 2. About four are provided. The position of the panel 2 is appropriately regulated by a pin and a pin bearing (not shown) so as not to be displaced back and forth and left and right by being biased by the spring 20.

Next, the operation of the above embodiment will be described.

Before use, it is as shown in FIGS. 1 and 2 (the recording pen, etc. are not shown), and the recording panel 2 is in the state of being in contact with the fixed pressing plates 5, 6, 7 by the bias of the spring 20. There is.

In order to mount the thin recording paper 23 on the upper surface of the panel 2 in such a state, the paper 23 is placed in the same manner as in the conventional case and then mounted by electrostatic attraction (see FIG. 5A). Thick recording paper
In order to mount 24, the panel 2 is pushed down against the urging force of the spring 20, and the paper 24 is pressed on the panel 2 by the fixed presser plates 7 and 6, one example of which is the edge and the lower edge. Position and place as much as possible. Then, while the pressing is released, the movable holding plate 12 is moved to the other side edge of the sheet 24 on the panel 2 which is lifted upward by the release, and the other side edge of the sheet is held by the holding portion 17. Hold down. As a result, the thick recording paper 24 has its upper and lower edges fixed by the fixed pressers 5, 6, the one side edge is fixed by the fixed presser plate 7, and the other side edge part is pressed by the movable presser plate 12 to lift the recording pen, etc. It is quickly and easily attached to the upper surface of the panel 2 without requiring the troublesome work of (3rd
See FIG. 5B).

FIG. 6 shows how to attach and use the thick recording paper 24 when it is long. In the case of such a long paper 24, a structure in which both sides of the substrate 1 are open is shown. Install as shown. In this case, the paper 24 can be moved left and right, that is, in the direction of the arrow in the drawing. In the drawing, X indicates the maximum width of the paper 24.

The above embodiment is only a preferable example, and it is an arbitrary design matter to use the spring 20 as a leaf spring which is not a coil spring, or to omit the fixed pressing plates 5 and 6, and other designs may be used. The present invention can be variously changed and modified within a range not requiring a gist.

(7), Effect of the Invention Since the invention has the above-described structure, the thin recording paper is mounted as in the conventional case, and the thick recording paper is pushed down the recording panel against the urging force of the spring. By releasing the pressing, the fixed pressing plate and the movable pressing plate can be pressed and mounted on the upper surface of the recording panel, and the mounting work can be performed extremely easily and quickly. Moreover, in this work, double-sided tape and the like are not necessary, and work such as lifting the recording pen is not necessary at all, and since these lifting mechanisms are not necessary, the structure is simple and above all, it is necessary to lift the recording pen. There is an excellent effect that it becomes possible to completely eliminate such defective recording.
