The mechanical chassis moves essentially on a horizontal plane at a load position and an ejecting position. At the load position, the mechanical chassis projects frontward from an outer cover housing of the video tape recorder for loading and/or ejecting a magnetic video tape cassette. Preferably, the recorder has at least two load positions and can perform recording and/or reproduction at either load position. At a first load position, the mechanical chassis is housed within the internal space of the recorder housing. At second load position, the mechanical chassis projects at least partway from the recorder housing. A push-button operated controller for operating the recorder is also disclosed. ## Claims ### Claim 1 A tape recorder comprising: a recorder housing; a mechanical chassis on which a recorder mechanism for recording and reproduction is mounted, said recording mechanism being adapted to receive a tape cassette including a tape serving as recording medium, wherein said mechanical chassis is able to move horizontally between an eject position in which it protrudes from said recorder housing to receive and eject said tape cassette and a first loading position housed within said recorder housing and in which said tape is received by said recorder mechanism for recording and reproduction and a second loading position to hold said tape cassette so that said tape cassette can be exposed to the outside of said recorder housing and that said tape is maintained at a loaded position for recording and reproduction;
