摘要： A video tape recorder (VTR) including a detection switch for detecting presence and absence of an erasure prevention tab of a video tape cassette, a light emitting element, a control device associated operatively with the light emitting element, and an electronic viewfinder. When a first video tape cassette provided with the erasure prevention tab as been loaded into the VTR, the control device sets the VTR to a recording standby state and turns on the light emitting element. Meanwhile, when a second video tape cassette which is not provided with the erasure prevention tab has been loaded into the VTR, the control device sets the VTR to a stop state, flashes the light emitting element and causes the electronic viewfinder to display on a screen of the electronic viewfinder a warning indicative of loading of the second video tape cassette into the VTR.
