ところが、従来は、下糸を監視する装置がなく、下糸の残量を予測することが できず、ミシン使用中に、作業を中断して下糸の残量を確認することが必要であ った。 However, conventionally, there is no device for monitoring the bobbin thread, and it is not possible to predict the remaining amount of the bobbin thread.Therefore, it is necessary to interrupt the work and check the remaining amount of the bobbin thread while using the sewing machine. It was.
【0005】 この考案は、上記のような課題を解決するためになされたもので、下糸の残量 を検出できるとともに下糸が不足した事を表示できる電子ミシンの下糸監視装置 を得ることを目的とする。The present invention has been made to solve the above problems, and provides a lower thread monitoring device for an electronic sewing machine that can detect the remaining amount of the lower thread and display that the lower thread is insufficient. With the goal.

この考案における下糸監視装置は、赤外線の感知、又は電極の通電により認識 され、その結果、表示装置に下糸の不足を表示する。 The bobbin thread monitoring device according to the present invention is recognized by detecting infrared rays or by energizing the electrodes, and as a result, displays a shortage of the bobbin thread on the display device.
【0008】[0008]
実施例1. 以下、この考案の一実施例を図に基いて説明する。図1はメカニカル式の下糸 監視装置において、フタ21をスライドさせる事により電極接触端子22を移動 させる事ができる。また、下糸が不足してきた場合電極接触端子22が電極セン サー23に接触し、通電する事で通電検知回路24が下糸の不足を検知し、表示 装置25に不足を表示する。図2は光学式下糸監視装置において赤外線照射回路 31において制御された赤外線を赤外線照射装置32において下糸不足時、下糸 がなくなり赤外線が通過し赤外線感知装置33において感知され赤外線検知回路 34において下糸の不足を検知し表示装置35に不足を表示する。 Example 1. An embodiment of the present invention will be described below with reference to the drawings. In the mechanical bobbin thread monitoring device shown in FIG. 1, the electrode contact terminal 22 can be moved by sliding the lid 21. Further, when the bobbin thread runs short, the electrode contact terminal 22 comes into contact with the electrode sensor 23 to energize, and the energization detection circuit 24 detects the shortage of the bobbin thread and displays the shortage on the display device 25. FIG. 2 shows that when the infrared ray irradiating device 32 has a shortage of the bobbin thread, the infrared ray controlled by the infrared ray irradiating circuit 31 in the optical bobbin thread monitoring device is detected by the infrared ray detecting circuit 34 when the infrared ray passes through the infrared ray detecting device 33. The shortage of the lower thread is detected and the shortage is displayed on the display device 35.
【0009】 次に、この実施例の動作について説明する。 図1のメカニカル式下糸監視装置に関して説明する。 下糸が充分ある場合はボビン1の下糸の厚みにより電極接触端子22と電極セ ンサー23の接触がはばまれ、通電しない状態である。下糸が消費されるととも に電極接触端子22が電極センサー23に近づき、やがて電極接触端子22と電 極センサー23が接触し通電する。この場合、通電検知回路24が通電を検知し 、表示装置に不足の表示を行う。Next, the operation of this embodiment will be described. The mechanical bobbin thread monitoring device of FIG. 1 will be described. When there is sufficient lower thread, the contact between the electrode contact terminal 22 and the electrode sensor 23 is blocked by the thickness of the lower thread of the bobbin 1 and no current is applied. As the bobbin thread is consumed, the electrode contact terminal 22 approaches the electrode sensor 23, and the electrode contact terminal 22 and the electrode sensor 23 come into contact with each other and energize. In this case, the energization detection circuit 24 detects the energization, and displays a shortage on the display device.
【0010】 図2の光学式下糸監視装置に関して説明する。 下糸が充分ある場合は、ボビン1の下糸の厚みにより赤外線照射装置32から 照射される赤外線が下糸に当たり、赤外線感知装置33まで届かない状態を保つ 。下糸が消費されるとともに赤外線が赤外線感知装置33に通過する様になり、 赤外線感知装置34にて赤外線の通過を検知し表示装置に不足の表示を行う。The optical bobbin thread monitoring device of FIG. 2 will be described. When the bobbin thread is sufficient, the infrared ray emitted from the infrared irradiating device 32 hits the bobbin thread due to the thickness of the bobbin 1 and keeps the infrared sensing device 33 from reaching the infrared ray. As the bobbin thread is consumed, infrared rays pass through the infrared sensing device 33, and the infrared sensing device 34 detects the passing of infrared rays and displays a shortage on the display device.
【0011】 なお、上記実施例では、電子ミシンの下糸の場合について説明したが、MTや カセットテープ、オープンリール等であってもよく、上記実施例と同様の効果を 奏する。In the above-described embodiment, the case of the lower thread of the electronic sewing machine has been described, but an MT, a cassette tape, an open reel or the like may be used, and the same effect as that of the above-described embodiment is obtained.
【0012】[0012]
以上のように、この考案によれば下糸の厚みを利用し赤外線の通過での検知と したので、装置が安価にでき、また、精度の高いものが得られる効果がある。ま た、構成部品が少なく信頼性が向上する。 As described above, according to the present invention, the thickness of the lower thread is used for detection by the passage of infrared rays, so that there is an effect that the apparatus can be inexpensive and a highly accurate one can be obtained. In addition, the number of components is small and the reliability is improved.
