Description
【考案の詳細な説明】
本考案は、教師が笛の孔を開閉した状態をランプで別に
掲示した表示板に明確に表現することが可能な教習用笛
に関するものである。[Detailed Description of the Invention] The present invention relates to a teaching whistle that allows the teacher to clearly indicate the opening and closing states of the whistle hole on a separate display board using a lamp.
本考案の目的は笛の孔の開閉を電気的装置を用いて生徒
に明瞭に表示できる斬新な笛を提供することにある。The purpose of the present invention is to provide a novel flute that can clearly display to students the opening and closing of the flute hole using an electrical device.
前記の目的を充足するため本考案は缶本体１に開孔した
指孔２の周りに指先によって導通する２つの導体電極３
及び４を設け、各電極３及び４をそれぞれ缶本体１に設

and 4 are provided, and each electrode 3 and 4 is connected to conductive wire strips 5, 5, . . . provided on the can body 1, respectively.
尚導通線条片５は缶本体１の下方に列設した接続端子６
，６・・・に連絡させである。The conductive wire strip 5 is connected to a connecting terminal 6 arranged in a row below the can body 1.
, 6... will be contacted.
又、導体電極３，４及び導通線状片５並びに接続端子６
は缶本体１に貼付しても良ければ、メッキにより形成し
ても差支えない。Moreover, the conductor electrodes 3, 4, the conductive wire piece 5, and the connection terminal 6
may be attached to the can body 1, or may be formed by plating.
導通線条片５はメインとなる導通片５ａに各電極からの
導通片５ｂを接続して構成上でいる。The conductive wire strip 5 is constructed by connecting conductive pieces 5b from each electrode to a main conductive piece 5a.
図中符号７は接続端子６よりジャンクを介して導出した
導線でその途中に検出回路８、表示回路９を介在させて
表示板１０，１０’の笛の絵１１に列設したランプ１２
に連絡させ、かつ五線譜表示１３にもランプ１４に連絡
させるようにしたものである。In the figure, reference numeral 7 denotes a conductive wire led out from the connection terminal 6 via a junk, with a detection circuit 8 and a display circuit 9 interposed in the middle, and lamps 12 arranged in line with the whistle picture 11 on the display boards 10 and 10'.
The lamp 14 is also connected to the staff score display 13.
尚又指孔２は最上位裏側のもの２′はその周りに電極４
のほか４′を設けて電極３と対向してあり、又表側下位
の指孔２ｒｙ、２ｒｔは更に小径指孔２ａを隣接して設
け、これに電極４〃と電極３を囲繞し、指を複雑に接離
しても操作を明確に表示ランプに表わすようにしである
。Furthermore, the finger hole 2 is the one on the back side of the uppermost layer 2', and the electrode 4 is placed around it.
In addition, a small diameter finger hole 2a is provided adjacent to the lower finger holes 2ry and 2rt on the front side, which surrounds the electrode 4 and the electrode 3, and the finger holes 2ry and 2rt are provided adjacent to each other. The operation is clearly indicated on the display lamp even if the movement is complicated.
検出回路８は第６図に示すようにインバーター１４．１
５を備え、表示回路９はトランジスター１６及びアンド
ゲート１７を設けて構成しである。The detection circuit 8 is connected to an inverter 14.1 as shown in FIG.
5, and the display circuit 9 includes a transistor 16 and an AND gate 17.
