The present invention relates to an apparatus for forming the present invention.

As shown in FIG. 3, in conventional blackboards of this type, a locker, shelf, or storage compartment 12 is often provided below the blackboard 11 in order to make effective use of space. In such cases, when attempting to install a powder receiving box, the traditional method of installing a powder receiving box requires that it be formed protruding from the bottom of the powder receiving gutter, so there is no space for installing a locker, etc. is affected. For this reason, such blackboards are usually not equipped with a powder receptacle.
このような従来の黒板では、チヨーク粉が樋の

た。
With such conventional blackboards, chalk powder accumulates on the gutter and a chalkboard wipe is placed on top of the gutter, so the next time the blackboard is wiped with a blackboard wipe, the board surface becomes even more dirty. There was a problem that when wiping the Chiyok powder with a wet rag, the wet Chiyok powder stuck to the gutter and was difficult to wipe off.
本考案は、このような従来の問題点を解消する
ことを目的とするものである。 The present invention aims to solve these conventional problems.
本考案は、黒板の下辺や側辺から突出しない状
態でチヨーク粉受け箱を設置できるようにしたも
のであり、以下図面に示す実施例に基づいて説明
する。
The present invention allows a chiyoke powder receiving box to be installed without protruding from the bottom or side of a blackboard, and will be described below based on an embodiment shown in the drawings.
第１図は本考案の構成を示すものであり、図中
１は黒板本体、２はチヨーク粉受け樋、３はチヨ

はクリーナである。 Fig. 1 shows the configuration of the present invention, in which 1 is the blackboard body, 2 is the chiyoke powder receiving trough, 3 is the chiyoke powder receiving box, 4 is the chiyoke powder receiving box storage frame, and 5
is a cleaner.
前記チヨーク粉受け箱３及び収容枠４には、樋
２側に開口部６が形成されており、クリーナ５の
側部先端が受け箱３内まで入るようにしている。
クリーナ５の前面には、樋２を清掃する際に手の
先を挿入するための挿入口５ａを設けて作業し易
いようにしている。 An opening 6 is formed in the dust receiving box 3 and the storage frame 4 on the side of the gutter 2, so that the side tip of the cleaner 5 can enter into the receiving box 3.
An insertion opening 5a for inserting the tip of a hand when cleaning the gutter 2 is provided on the front surface of the cleaner 5 to facilitate the operation.
本考案は上記のような構成であるので、樋２上

ことができる。 Since the present invention has the above-described configuration, when cleaning the dust on the gutter 2, the cleaner 5 is swept from one side of the gutter 2 to the other, and the tip of the cleaner 5 reaches the opening 6 of the receiving box 3. If the powder is pushed away, the powder will enter the receiving box 3, and after cleaning, the receiving box 3 can be taken out to the front and the powder inside can be thrown away.
上述したように本考案によれば、樋の下に突出

棚のスペースに影響を与えることなく設置が可能
であり、また既設の黒板にもチヨーク粉受け箱を

ある。
As mentioned above, according to the present invention, the powder receiving box can be installed without protruding below the gutter, so even if you use a shelf under the blackboard, it can be installed without affecting the shelf space. This is possible, and it also has the effect of allowing the powder receiving box to be installed on an existing blackboard.
