[0001]

[Industrial applications]

 The present invention relates to a posting device suitable for posting thin paper such as half-paper.

[0002]

[Prior art]

 In a calligraphy class, when students correct or write a piece of work written on a half-paper, or when evaluating or judging a work, it is necessary to put the half-paper on the easy-to-see position in the classroom. As a method of posting works written in, etc., for example, a method of fixing the half-paper on the surface of the blackboard with a magnet or the like, a method of fixing it to a wall with a push pin, or a horizontal oblong body inside the cover body, A method of using a plug-in type fixing tool that has a notch for insertion in the longitudinal direction on the lower side of the cover body and the upper end of the half-paper is pinched and fixed by inserting the upper end of the half-paper into the notch, etc. Is being done.

[0003]

[Problems to be solved by the device]

 However, according to the above method, first, in the method of fixing the half-paper etc. with the magnet, it is necessary to hold the half-paper in a fixed position on the blackboard and place the magnets on the left and right of the upper end of the half-paper, which is complicated work . In addition, the method of fixing with a push pin is dangerous because the wall to be fixed or the half-paper can be damaged by the tip of the push pin, and the hand can be damaged by the tip of the push pin during fixing work. .

In addition, the method using the plug-in type fixture has a problem that it takes time to work because it is difficult to insert the upper end of the half-paper into the notch for insertion.

Further, in all the fixing methods described above, in the process of correcting hundreds of works written on a half-paper or the like one by one, or in the process of screening and selecting works, the half-paper is first fixed to the wall surface. However, it is necessary to repeat the work of removing from the wall after the inspection, which is very time-consuming and complicated because there are many works.

An object of the present invention is to provide a bulletin board device that solves the above problems.

[0007]

[Means for Solving the Problems]

 According to the present invention, the closed hollow pipe is positioned in the lateral direction, a plurality of suction holes are provided on the front side of the hollow pipe, and the inner hollow portion of the hollow pipe and the air suction device are appropriately connected, Moreover, the present invention provides a bulletin board device characterized in that it is configured to generate a negative pressure at the position of the suction hole so that thin paper or the like can be adsorbed and held.

【Example】

 (Embodiment 1) As shown in FIG. 1, a bulletin apparatus A of the present invention has a hollow pipe 1 formed in a hermetically sealed state in a horizontal direction, and a hollow portion 1a inside the hollow pipe 1 and an air suction device. The hollow pipe 1 is fixed to the wall surface by the wall surface fixing tool 3 for use.

Since a plurality of suction holes 2 are provided on the front side of the hollow pipe 1, when the air suction device 5 is operated, a negative pressure is generated at the position of the suction holes 2 and the suction holes 2 are generated. By contacting the thin paper 6 such as a half-paper at the 2 position, the thin paper 6 can be sucked and held at the suction hole 2 position.

The suction pipe 1 is not particularly limited in shape as long as it is hollow and horizontally long, and the shape can be determined according to the shape of the thin paper 6 or the like to be displayed. As a structure that can be installed continuously, the length can be freely adjusted according to the lateral length of the wall.

The plurality of holes 2 provided on the front side of the suction pipe 1 are not limited in shape and number, but when a rectangular thin paper such as a half-paper is posted, as shown in FIG. The position of the suction hole 2 may be set so that the upper end can be held by two or more suction holes 2.

On the upper side wall portion of the suction pipe 1, a caul plate 7 is provided along the hollow pipe 1 in a horizontally long shape and protrudes from the front surface, and a thin paper 6 or the like is posted as shown in FIG. In some cases, make it easy to put on and take off as a mark of the posting position.

Further, the suction pipe 1 is provided with a wall surface fixing tool 3, and, for example, as shown in FIG. 1, hooks 7a provided at both ends of the contact plate 7 are connected to the string-like bodies 3a, respectively. The cord-like bodies 3a are hung on the pulleys 4 each having the same width as the suction pipe 1 on the wall surface, and the cord-like bodies 3a, 3a are combined into one on one pulley 4 side, and the end portion 3b is walled. By fixing the suction pipe 1 to the wall surface by fixing the suction pipe 1 to the wall 9 and adjusting the position of the end 3b, the fixed position of the suction pipe 1 can be moved up and down. ing.

In order to fix the suction pipe 1 without using a wall surface, for example, a column is provided in the vertical direction at the center of the suction pipe 1 installed in the horizontal direction, and a column for moving is provided at the lower end of the column. It is also possible to provide a car part of the car, and by using the car part, the suction pipe and the support can be held on the floor surface, and the car part can be slid to be freely moved.

An air suction device 5 is connected to the hollow portion 1a of the suction pipe 1 via a hollow connecting pipe 8 and the like, and the air suction device 5 has a motor 5b inside and a power cord. 5
It is connected to a power source at c and operates the suction fan 5a by rotating the motor 5b, which has a function of sucking air like a suction device such as a vacuum cleaner. The air suction device 5 is required to stably hold the thin paper 6 and the like and to have a suction force sufficient to cause the suction hole 2 to have a suction force that is easy to attach and detach.

The bulletin device A having the configuration described above operates the air suction device 5 to apply negative pressure to the suction hole 2 portion of the suction pipe 1 to suck thin paper 6 or the like into the suction hole 2 portion. Therefore, the posted thin paper 6 and the like can be easily attached and detached, so that the labor conventionally required for posting a wall or the like can be significantly reduced.

The display device of the present invention is suitable for use in a calligraphy classroom or the like for displaying a work written on a half-paper while making corrections or judging, thereby significantly reducing the working time. You can measure. Moreover, it is possible to easily attach and detach the half-paper without damaging it. In addition, the half-thirsty works can be used for drying works, etc. without polluting the walls.

Further, the signage device of the present invention is not limited to the half-paper, but is suitably used for signage of thin paper, especially for applications in which thin paper is frequently attached and detached.

Second Embodiment Although the basic configuration is the same as that of the first embodiment, innumerable fine holes are provided as the suction holes 2 and the air suction device 5 is connected to both ends of the hollow pipe 1. They are provided separately, and the partition 10 is provided in the inner hollow portion 1a of the hollow pipe 1, which is a difference.

Specifically, as shown in FIGS. 3 and 4, as the suction holes 2, a large number of fine holes having a size of about a needle hole are provided on the front side of the hollow pipe 1, so that the suction holes 2 The size of the paper is not limited by the position, and it is possible to display paper of any size.

In addition, when the partition 10 is provided in the inner hollow portion 1a of the hollow pipe 1 and the air suction devices 5 are directly provided at both ends of the hollow pipe 1, when one half of the blank paper 6 to be posted is small, one of By operating only the air suction device 5 and setting only the hollow pipe 1 on one side with the partition 10 as a boundary to a negative pressure state, it is possible to save power consumption. Further, by directly connecting the air suction device 5 to the hollow pipe 1, the display device A becomes compact and easy to handle. 5d shows a changeover switch.
