Claims

[Claims for Utility Model Registration] (1) The media holding stand attached to the end of the rotating shaft of the motor is made of synthetic resin mixed with magnetic powder or grains, and the holding stand is provided with a through hole. A plate spring, which is provided through the through hole and is attached to one end of a torque transmitting body that rotates the media together with the media holder, is rotatable via a pivot on the back surface of the media holder. A spring receiving part that is attached to the plate spring and deflects the spring part by guiding the linear motion of the other linear end connected to the spring part forming the intermediate part of the leaf spring is integrally formed on the back surface of the media holding base. A media holding device for a protruding media drive device, characterized in that the other linear end is formed by double bending, and the outer surface of the bent part is in sliding contact with the spring receiving part. Media holding device for drive equipment. (2) A through hole is provided in the media holding base attached to the end of the rotating shaft of the motor, and a torque transmitting body is provided at one end to pass through the through hole and rotate the media together with the media holding base. The attached leaf spring is rotatably attached to the back surface of the media holding base via a pivot shaft, and the linear movement of the other straight end connected to the spring part forming the middle part of the leaf spring is guided so that the above-mentioned In a media holding device for a media drive device in which a spring receiving part for deflecting a spring part is provided protruding from the back surface of the media holding base, the media holding base is integrally formed with the pivot shaft and the spring receiving part. The main part of the stand is made of a material that has a low coefficient of friction and has a small coefficient of friction, and the table surface part is made of synthetic resin and is coated on the surface of the main part and is mixed with magnetic powder or grains. Features: Media holding device for media drive equipment.
