Recording apparatus includes a planar support for supporting a flat recording medium such as one or more circular graph sheets. At least one recording instrument, e.g., a wire pen, is arranged to be movable relative to the support to provide a recording on the recording medium when the instrument is moved into contact with the medium and the medium is driven at a given rate. A lid is provided for covering the recording medium, the lid being arranged for pivotal movement about a hinge axis between open and closed positions relative to the support. The lid also serves to move the recording instrument into contact with the recording medium when it is in the closed position, and to lift the recording instrument out of contact from the recording medium when in the open position. A movable, guide part contacts the recording instrument to lift the instrument out of contact from the recording medium when the lid is moved to the open position. A drive arrangement is provided between the lid and the guide part to provide lifting movement to the guide part when the lid is pivoted toward the open position, so that the recording instrument is firmly supported out of contact with the recording medium and cannot be tampered with to make false recordings while the lid is open.
Recording apparatus comprising a planar support for supporting a recording medium, means for driving the recording medium at a given rate, at least one recording instrument arranged to be movable relative to said support for providing a recording on the recording medium when said recording instrument is moved into contact with the recording medium and the recording medium is driven, a lid for covering the recording medium wherein said lid is arranged for pivotal movement about a hinge axis which extends parallel to said planar support between open and closed positions relative to said support to move said recording instrument into contact with the recording medium when said lid is in said closed position and to raise said recording instrument out of contact from the recording medium when said lid is in said open position, a guide part which is movable into contact with said recording instrument to raise said recording instrument out of contact from the recording medium when said lid is moved toward said open position, and drive means between said lid and said guide part for providing movement to said guide part when said lid is pivoted from said closed position toward said open position so that said recording instrument is held in a fixed position out of contact from the recording medium.
