昇による伸縮等があげられる。One of the important functions of a flexible disk device is track positioning accuracy. This refers to the positioning accuracy of the magnetic head with respect to a specified track position in the radial direction of the flexible recording medium, and if this positioning error becomes large, it becomes impossible to read data recorded on the flexible recording medium by another device. So-called compatibility cannot be ensured. For this reason, in a flexible disk device, components related to track positioning of a magnetic head generally maintain extremely high accuracy in order to ensure compatibility of flexible recording media. Error factors that make track positioning of the magnetic head difficult include the precision of parts in the head feed mechanism, motor characteristics,
Examples include expansion and contraction of the flexible recording medium and device component parts due to temperature changes in other parts such as head mounting errors, and expansion and contraction due to temperature increases within the device due to heat generated by spindle drive motors, pulse motors, etc.

実施例について詳細に説明する。Furthermore, the problem of temperature rise inside the device due to motors, etc. causes track positioning errors, and there is also a restriction that the value added to the guaranteed upper limit of the environmental temperature of the device must be less than the upper limit of the usable temperature of the flexible recording medium. have.
In any case, it is advantageous to have a lower temperature rise value inside the device, and it is also very important for the functionality of the flexible disk device.The present invention focuses on this point and provides a centrifugal fan on the output shaft of the spindle drive motor to drive the spindle. This paper proposes a means to more effectively reduce the temperature rise inside the device by reducing the temperature rise of the drive motor itself and at the same time passing the air passage on the exhaust side between the frame base and the circuit board inside the device. be. An embodiment of the present invention will be described in detail below based on the drawings.

In the figure, when each power supply voltage is applied to the device, the spindle drive motor rotates the flexible recording medium 1 at a specified rotation speed via the motor pulley 1, the belt 6, and the spindle pulley 4, and at the same time, the output shaft of the spindle drive motor 5 The centrifugal fan fixed to 12 also rotates, but in this case, the heat generated by the spindle motor is dissipated by the rotation of centrifugal fan 13, which sucks air from the motor casing side as shown by the arrow in the figure, and is further sucked in. The flow of air is discharged to the lower side of the frame base 15 in a right angle direction.

It can also be expected to have the effect of dissipating the heat generated by the pulse motor.
In this case, the discharged air is slightly warmed through the heat dissipation of the spindle drive motor, but the temperature itself is not that high, and the cooling effect of the moving wind is far greater. .
