Abstract

(57) [Summary] [Structure] A pair of rubber magnet sheets 2 and an underlay plate 1
Is reversibly connected to. [Effect] Even if the paper is pulled out, the paper does not break. When both sides of the paper are used, the paper can be turned over easily and efficiently.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an underlay which is used by fixing an end portion of a sheet.

[0002]

[Prior Art]

 Generally, as an underlay for fixing the end portion of the paper, it is known that a metal spring clip 7 is attached to the center of the end of the plastic underlay plate 6 shown in FIG. The sheet 3 is fixed by sandwiching its ends with spring clips 7, and is placed on the surface of the underlay plate 6. Therefore, it is possible to easily write a sentence or the like on the sheet 3 even at a place other than the desk.

[0003]

[Problems to be solved by the device]

 However, when both sides of the paper 3 are used, the paper 3 sandwiched by the spring clips 7 must be removed and turned inside out. The work of turning over the paper 3 was troublesome and very inefficient. Further, when removing the paper 3 from the spring clip 7, if the paper 3 is pulled out vigorously without raising the spring clip 7, the end of the paper 3 pressed by the spring clip 7 may be broken.

Therefore, an object of the present invention is to provide an underlay which can easily and efficiently turn over the paper without fear of tearing the paper when using both sides of the paper.

[0005]

[Means for Solving the Problems]

 In order to solve the above technical problems, the underlay of the present invention is such that a pair of rubber magnet sheets are reversibly connected to an underlay plate so that paper can be sandwiched between the pair of rubber magnet sheets. It is characterized by.

[0006]

[Action]

 According to the above configuration, the pair of rubber magnet sheets can hold the paper sheet in a freely sandwiched manner. Further, since the pair of rubber magnet sheets are reversibly connected to the underlay plate, the sandwiched sheet can be turned over to the other surface of the underlay plate together with the pair of rubber magnet sheets.

【Example】

 An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a plan view of an underlay of an embodiment of the present invention. The construction of the underlay shown in the figure includes a rectangular underlay plate 1 made of plastic or the like, a pair of elongated rubber magnet sheets 2, and a stopper 4 formed of plastic or the like in a ring shape. is there.

The underlay plate 1 is provided with a plurality of pairs of holes 11 at equal intervals in the central portion in the short side direction. The stopper 4 is inserted into each of the pair of holes 11. The rubber magnet sheet 2 is provided with a plurality of holes 21 at one end on the long side thereof. The pair of rubber magnet sheets 2 are connected to the underlay plate 1 in a reversible manner by inserting the holes 21 into the stoppers 4.

According to the underlay of this embodiment, the following operational effects can be obtained. The pair of rubber magnet sheets 2 allows the paper 3 to be sandwiched. Therefore, even if the paper 3 is pulled out, the sandwiched portion of the paper 3 does not break. Further, since the pair of rubber magnet sheets 2 is connected to the underlay plate 1 in a reversible manner, the sandwiched paper 3 can be turned over to the other surface of the underlay plate 1 together with the pair of rubber magnet sheets 2. Therefore, when the back surface of the paper 3 is used, the paper 3 can be turned over easily and efficiently.

FIG. 2 is a plan view showing another embodiment of the present invention. The structure of this embodiment is different from the above-mentioned embodiment in that a plurality of holes 12 are provided at the short side ends of the underlay plate 1 at equal intervals, and the stoppers 4 are inserted into these holes 12. The other structure is the same as that of the embodiment shown in FIG.

According to the underlay of this embodiment, in addition to the same effects as those of the embodiment of FIG. 1, both the front and back sides of the underlay plate 1 can be used as the underlay. The size may be about the same. Therefore, when the same paper size is used, it can be made more compact than the embodiment of FIG. In each of the above embodiments, the stopper 4 is attached to the underlay plate 1 by forming the holes 11 and 12, but it may be attached to the underlay plate 1 using a conventionally known means.

FIG. 3 is a perspective view showing another embodiment. The structure of this embodiment is different from that of FIG. 2 in that the stopper 4 is replaced with a connecting plate 5 having a hinge portion 52. The connecting plate 5 has one end attached to the end of the underlay plate 1 by two screws 51. Further, the other end of the connecting plate 5 is formed with a forked holding portion 53 for holding the pair of rubber magnet sheets 2.

In the underlay of this embodiment, the sheet 3 sandwiched between the pair of rubber magnet sheets 2 can be turned over together with the rubber magnet sheet 2 with respect to the underlay plate by the hinge portion 52 of the connecting plate 5. It is possible. This embodiment can also achieve the same effects as the above embodiments. Besides, various design changes can be made within the scope of the invention.

[0014]

[Effect of the device]

 As described above, according to the underlay of the present invention, the paper can be sandwiched between the pair of rubber magnet sheets. Therefore, even if the paper is pulled out, the part where the paper is sandwiched does not break. Further, since the pair of rubber magnet sheets are reversibly connected to the underlay plate, the sandwiched sheet can be turned over to the other surface of the underlay plate together with the pair of rubber magnet sheets. Therefore, when the back side of the paper is used, the paper can be turned over easily and efficiently.
