Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blackboard with a copying function that can be used for education, meetings, and the like.

2. Description of the Related Art In recent years, a blackboard with a copying function that can copy the written content on the blackboard has been provided, and its utility value is being highly evaluated, such as saving the trouble of writing memos and creating minutes. Hereinafter, a conventional blackboard with a copying function will be described with reference to FIGS. 5 and 6.
FIG. 5 is a front view of the blackboard with a copying function, and FIG. 6 is a block diagram showing the configuration of the blackboard with a copying function.

In the figure, reference numeral 1 denotes a blackboard main body case, inside which a supply side reel 3a for supplying a drawing sheet 2 and a winding side reel 3b for winding the drawing sheet 2 are provided. Again 4
Is a light source that irradiates the surface of the drawing sheet that is being rolled up, and generally uses a fluorescent lamp. Reference numeral 5 is a mirror that reflects the reflected light from the drawing sheet. Reference numeral 6 denotes a lens that collects the reflected light from the mirror 5 and forms an image on an image sensor 7 such as a CCD (charge coupled device). Reference numeral 8 denotes a reflecting plate arranged to reflect the light from the light source 4 and illuminate the image reading surface 2a on the drawing sheet. An image information processing unit 9 inputs an output signal from the CCD and creates a signal to the output device 10 so as to obtain a copy image of the drawing sheet surface. This output device 10
Outputs a hard copy 13.

Reference numeral 11 denotes a stand, which is fixed to the left and right side portions of the blackboard body case 1 with bolts 12.

Problems to be Solved by the Invention Generally, since a blackboard with a copying function is convenient, in many cases it is moved to another place instead of being installed only in a specific place. If the overall height is low, you can buy it safely and move it smoothly. However, in the conventional blackboard with a copy function, it is difficult and dangerous to move alone, and the opening of the room is low. For this reason, the main body case and the stand section had to be disassembled for transportation. Further, since the blackboard body case body is large and heavy, it is necessary to perform the work by at least two persons when assembling the blackboard body case with the stand portion, which is dangerous as described above. In addition, during packing, the blackboard body case and the stand were to be disassembled for storage, and the size of the storage case was increased, leading to an increase in transportation costs.

The present invention has been made in view of the above conventional problems, and an object of the present invention is to eliminate the risk of movement and to facilitate the transportation, simplification of the assembly, and the packing and storage case. It is an object of the present invention to provide a blackboard with a copy function that can realize miniaturization.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention comprises a blackboard main body having a writable drawing sheet, and a base part supporting the blackboard main body, and the blackboard The lower end of the main body is rotatably supported by the base, so that the upper end of the blackboard main body can be folded to a state below the lower end of the blackboard main body. .

In the copying function blackboard of the present invention, since the lower end of the blackboard main body is rotatably supported by the base part, it is possible to rotate the lower end of the blackboard main body above the upper end. Since the center of gravity of the entire blackboard with copy function is lowered due to the weight of the blackboard body, the blackboard with copy function can be easily transported.

Further, since the entire height of the blackboard with a copying function is lowered, by using the caster portion at the lower end portion of the base portion, it is possible to easily transport the blackboard with a ceiling or a place with a low opening by one person.

Embodiment An embodiment of a blackboard with a copying function according to the present invention will be described below with reference to FIGS.
This will be described with reference to FIG.

FIG. 1 is a front view of a blackboard with a copying function according to an embodiment.
2 is a side view thereof, FIG. 3 is a sectional view taken along line AA of FIG. 1,
FIG. 4 is a perspective view of the blackboard body case in a folded state.

In the figure, 21 is a blackboard main body case, a drawing sheet 22 formed in a loop shape inside thereof, and a part of which is exposed from the blackboard main body case, and a pulley 23a and a pulley 23b for stretching the drawing sheet 22. It is provided. Further, 24 is a light source for illuminating the surface of the drawing sheet being conveyed, and a fluorescent lamp is used in this example.
Reference numeral 25 is a mirror that reflects the reflected light from the drawing sheet, and 26 is a lens that collects the reflected light from the mirror 25, and is an image sensor such as a CCD (charge coupled device).
Image on 27.

The respective components between the numbers 22 to 27 are arranged in the blackboard body case.

Reference numeral 28 denotes a base portion that supports the blackboard body case 21, and a power source portion 29 and a recorder 3 that makes a hard copy 31 by an electric signal from the image sensor 27 on the base portion 28.
0, and a control circuit 32 for controlling the operation of each part is provided.

Further, 33 is a bolt for fixing the blackboard main body case 21 and the base part 28, and when the blackboard with the copying function is packed or moved, it is a fourth bolt in a loosened state or a removed state. As shown in the figure, the blackboard body case 21 can be folded by a hinge 34 mounted between the blackboard body case 21 and the base portion 28.

EFFECTS OF THE INVENTION In the blackboard with a copying function of the present invention, the blackboard body case is configured to be rotatable with respect to the base portion, so that the blackboard body case is bent with respect to the base portion when the blackboard with a copying function is stored. As a result, the packing and storage case can be downsized.

Further, since the center of gravity of the entire device is lowered by bending the blackboard body case with respect to the base part, there is an excellent effect such as ensuring safety during movement in the folded state.
