ABSTRACT:
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.
