Claims

[Claims for Utility Model Registration] 1. Head support for a double-sided flexible disk device that is equipped with heads that press the upper and lower surfaces of a double-sided flexible disk from above and below, facing each other across the double-sided flexible disk. In the apparatus, a carriage having a first head; and an arm having a second head, the arm being rotatably attached to the carriage about a first rotation support so that the flexible disk can be attached and detached. and a top cover with which the upper end surface of the arm abuts in the upward rotational position of the arm, and the arm is provided between the first rotation support part and the second head. 1. A head support device for a double-sided flexible disk device, comprising two parts, a first arm and a second arm, which are rotatable about a second rotation support part. 2 The first arm and the second arm are configured such that the arm portion provided on the first arm abuts the stopper portion provided on the second arm by a coil spring provided on the second rotation support portion. 2. The head support device for a double-sided flexible disk device according to claim 1, further comprising a configuration in which the head support device is biased to the side. 3 The first arm and the second arm are such that the arm portion provided on the first arm abuts the stopper portion provided on the second arm due to a leaf spring provided on the second rotation support portion. 2. The head support device for a double-sided flexible disk device according to claim 1, further comprising a biased configuration. 4. The head support device for a double-sided flexible disk device according to claim 1, 2 or 3, wherein the top cover with which the upper end surface of the arm abuts has a wear-resistant member provided at its abutting portion.
