  • Publication number: 20110211804
    Abstract: The present invention provides a video display device provided with a storage mechanism that reliably holds a recording medium (HDD) with the reduced number of components. A tray integrally stores an installed HDD built in the device and a cassette HDD attachable to and detachable from the device, and is mounted on a main chassis. An HDD stopper of a hook-like shape integrated with the tray presses an end part of the installed HDD to secure its storage position. An HDD holder integrated with the tray presses a side surface at an end part of the cassette HDD to prevent it from falling off the tray. Further, a regulating plate formed by cutting and raising the main chassis suppresses deformation of the HDD stopper, and an anti-falling plate prevents the installed HDD from falling off the tray.
