Abstract

A disc clamping device having: a clamp lever supported freely rotatable; a plate spring one side of which is fixed to the clamp lever; and a clamp facing a turntable on which a disc is placed. The position of the leaf spring is supported in a freely rotatable manner, and the disk is pressed against the turntable by the turning action of the clamping lever, wherein the clamping lever has a support for the leaf spring. The arm portion, the leaf spring, has a flange portion supported by the arm portion, and the leaf spring is pressed by the arm portion of the clamp lever in a state where the clamp is not pressing the disc. The flange portion of the clamp is supported, the leaf spring is in an elastically deformed state, and generates an elastic force downward, that is, in the pressing direction of the clamp, and the leaf spring is acted upon by the elastic force. Accordingly, the present invention provides a disc clamp device that reduces fluctuations in pressing force corresponding to fluctuations in the stroke of the clamp lever.

Description

technical field [0001] The present invention relates to a disc clamping device. More particularly, it relates to a disc clamping device for pressing an inserted disc against a turntable provided in a disc loading device for loading a disc-shaped recording medium such as a CD or DVD. Background technique [0002] In recent years, as a device for loading disc-shaped recording media such as CDs and DVDs (hereinafter simply referred to as "discs"), there has been known a device in which a disc is directly inserted into the device without using a tray on which the disc is placed. Slotted loading device. [0003] This slot-type loading device grips a part of the inserted disk, and carries it into the device so that the disk is seated at a predetermined position on the turntable. The slot-type loading device does not require a tray for loading the disk, so it can be thinner than a loading device using a tray. [0004] In the aforementioned slot-type loading device, in order to r...
