DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view showing a state in which an electronic blackboard is supported by a stand according to the present invention. In the figure, reference numeral 10 denotes an electronic blackboard, and reference numeral 11 denotes a stand.
[0013]
The electronic blackboard 10 has a horizontally long flat shape as a whole, and includes a base frame 12 that supports the whole on the rear side. The base frame 12 is formed in a rectangular frame shape with left and right vertical frames 13 and upper and lower horizontal frames 14 each consisting of a square pipe.
[0014]
An endless writing sheet 15 is stretched between left and right rollers rotatably supported on the front side of the base frame 12, and a part of the sheet 15 is front of the frame-like window frame 16 attached to the base frame 12. The writing surface S is formed on the window a. In the electronic blackboard 10, an optical reader is attached to the back of the writing sheet 15 and supported by the base frame 12.
[0015]
Further, a printer 17 and an operation unit unit 18 provided with various switches and the like are attached to the lower horizontal frame 14 of the base frame 12, while an elongated plate-like pen tray 19 is installed along the lower edge of the window frame 16. It is provided.
[0016]
When the electronic blackboard 10 is used, characters, pictures, etc. are written on the writing surface S using a writing tool such as a marker pen on the pen tray 19.
[0017]
When copying the written content, the copy switch on the operation unit 18 is pushed to convey the writing sheet 15, the written content on the sheet is read by the optical reader, and the signal from there is input to the printer 17 for reading. The recorded paper is discharged while the content is reduced and recorded on the paper stored in the printer. When erasing the written content, for example, the writing surface S is wiped with an appropriate eraser placed on the pen tray 19 to erase the written content.
[0018]
As shown in FIG. 2, the stand 11 is composed of a pair of left and right leg main bodies 30 and one connecting frame 35.
[0019]
Each leg main body 30 includes a lower leg 22 and a column member 26 provided on the leg 22 in a standing manner. The foot 22 is formed by, for example, attaching a protective cap 24 to both ends of a square pipe and placing the caster 25 on the lower surface of both ends. The column member 26 is formed by attaching a joint member 28 to an upper end of a square pipe, for example. The leg body 30 is formed in an inverted T-shape by fixing the lower end of the column member 26 to the center of the upper surface of the foot 22 and fixing it by welding or the like.
[0020]
The connecting frame 35 is formed in an H shape by connecting, for example, by welding, a pillar member 27 made of a square pipe having the same outer shape as that of the pillar member 26, at both ends of one reinforcing stay 21 made of a square pipe. Become. A joint member 29 is attached to the upper end of each column member 27 in the figure.
[0021]
The joint members 28 and 29 are formed by bending a sheet metal into the same mouth shape so that it can be inserted into the column member 27 or the lower end opening of the vertical frame 13 of the electronic blackboard 10 together. Then, the lower end portions are respectively inserted into the column members 26 and 27 and fixed by spot welding or the like, and the upper end connecting portions 28a and 29a are protruded upward. Short square pipes may be used as the joint members 28 and 29.
[0022]
For example, when packing at a factory at the time of shipment, the above-described stand 11 is stored in a packing box in a state of being separated into a pair of leg main bodies 30 and one connecting frame 35.
[0023]
For example, when the stand 11 is assembled at the shipping destination, the leg main body 30 is arranged at an appropriate interval, the connection frame 35 is lifted, and the connection portion 28 a of the column member 26 is inserted into the column member 27. The lower edge of the column member 27 is abutted against the upper edge of the column member 26 to connect the column members 26 and 27 in a straight line. Thus , the column members 26 and 27 constitute a support column 23, and the support column 23 and the foot 22 form a leg 20 on the left and right. Then, desirably, the column member 27 is screwed to the column member 26 and the connecting frame 35 is fastened to the leg main body 30.
[0024]
Thereafter, the electronic blackboard 10 is lifted, the connecting portion 29a of the column member 27 is inserted into the lower end opening of the vertical frame 13, and the lower edge of the vertical frame 13 is abutted against the upper edge of the column member 27 so that the column member 27 and the vertical frame 13 are connected in a straight line. Then, the vertical frame 13 is screwed to the column member 27 to fix the base frame 12 on the stand 11.
[0025]
By the way, the reinforcement stay 21 may be configured such that both ends thereof are screwed to the column member 27 when the stand 11 is assembled. In that case, the connecting frame 35 is housed in the packing box together with the leg main body 30 in a state where the connecting frame 35 is further separated into the reinforcing stay 21 and the two left and right column members 26 and 27.
[0026]
If the electronic blackboard 10 is to be used, for example, at a height that is one step lower, the column member 26 of the leg main body 30 is directly screwed to the vertical frame 13 without using the connecting frame 35, and the column 23 is moved one step. The electronic blackboard 10 is supported in a shortened state. Thereby, the electronic blackboard 10 can be used at a desired height position that is lower by the length of the column member 27.
[0027]
Further, in the above-described embodiment, each column 23 of the stand 11 is configured by the two column members 26 and 27, but may be configured by three or more column members.
[0028]
For example, as shown in FIG. 3, each strut 23 of the stand 11 may be configured to be linearly connected so as to be divided into three pillar members 40, 41, and 42. In the example of FIG. 3, the writing board is a white board 45 in which white writing surfaces S are formed on both front and rear surfaces, and the white board 45 is supported by the stand 11 so as to be rotatable about a support shaft 46.
[0029]
【The invention's effect】
Therefore, according to the first aspect of the present invention, the left and right support columns of the stand are divided into a plurality of column members. It becomes easy to perform, and assemblability can be improved accordingly. In addition, when the stand is shipped or transported, the column is divided into a plurality of short column members, so that the components before assembly can be made smaller and the packaging form can be made smaller. Can be easily.
[0030]
In addition, since the column is divided into a plurality of column members, the number of column members to be connected can be appropriately selected at the time of assembly, and the column length can be arbitrarily adjusted. The height position of the writing board can be adjusted. Further, when the column is used with a shorter length, it can be easily moved while being stabilized by, for example, a caster.
[0031]
According to the second aspect of the present invention, at the time of assembly, the writing board itself or a member that supports the writing board is directly connected to the pair of left and right leg main bodies without using the connecting frame, thereby shortening the support column by one step. Since the writing board can be supported in the state, the writing board can be used at a desired height position that is lower by the length of the connecting frame column member .
