Summary:To enable a sewing machine user to effectively take measures to solve errors not only by detecting a plurality of types of errors occurring in a bobbin case exchange device but also by notifying the sewing machine user of the type of the error occurred to allow the user to know the kind of error without checking the bobbin case exchange device.SOLUTION: An error detector 40 of a bobbin case exchange device is configured to include a dog 41 having a plurality of detected sections at a rotation position corresponding to the type of error, a sensor 51 to detect the detected section at which the dog 41 arrives by rotation, a control device 70 to identify and output the kind of error depending on difference in arrival timing of the detected section detected by the sensor 51, and a transmission device 80 to transmit the kind of error output from the control device to a sewing machine user.SELECTED DRAWING: Figure 7 【課題】ボビンケース交換装置で発生する複数種類のエラーを検出するだけでなく、いずれのエラーが発生したのかをミシン使用者に伝達してボビンケース交換装置を調べなくても分かるようにし、エラーを解消する処置を効率的に行えるようにする。【解決手段】ボビンケース交換装置のエラー検出装置40は、エラーの種類に応じた回転位置に複数の被検知部が設けられたドグ41と、ドグ41の回転により到達する被検知部を検知するセンサー51と、センサー51が検知した被検知部の到達タイミングの違いによりエラーの種類を識別して出力する制御装置70と、制御装置が出力したエラーの種類をミシン使用者に伝達する伝達装置80とを含み構成されている。【選択図】図7
