As described above, according to the present invention, when the front portion 84 of the cap C is desired to be embroidered, the cap C is attached to the cap frame A, and the cap frame A is connected to the embroidery sewing machine. It is of course possible to place a hat at the needle drop position of the embroidery sewing machine and embroider on it, and to attach the hat C to the embroidery frame A and to connect the embroidery frame A with the hat C to the embroidery sewing machine. In both of the two steps, the relative positional relationship of the cap C with respect to each of the two position confirming members 48 and 49 can be visually observed, and if the cap C is inclined with respect to the cap frame A, Can be detected with a high probability and the correction can be promptly promoted. As a result, there is an effect that the possibility of providing an appropriate product with appropriate embroidery can be extremely increased.

In the case of the embroidery on the front part 84, the base part of the eaves 85
When 85a is sandwiched between the abutting portion 28a and the receiving portion 50, it serves as an anchor to keep the integrity of the hat C to the hat frame A extremely high, and the front face portion 84 of the hat is as large as the needle. Even thick ones that give resistance can be accurately embroidered by preventing the deviation.

If the hat frame holder Be is equipped with the above-mentioned position confirmation members 48e and 49e, the hat position can be always confirmed by using the same position confirmation members 48e and 49e when the hats are attached to a large number of hat frames, respectively. Therefore, hats can be attached to a large number of hat frames in a constant positional relationship without variation.
