    摘要: The output voltage of an AM synchronous detector is compared with a reference potential level by a voltage comparator. A muting device connected with the output of the detector is controlled by a control circuit connected with the comparator. Through this control circuit, the detector output is immediately muted when the detector output level falls below the reference potential level, and the muting of the detector output is removed after a predetermined retardation when the detector output level exceeds the reference potential level.

    摘要: A recording apparatus includes a recording head which is scanned, a supply system containing an amount of ink and a detector for the residual ink quantity in the supply system. The residual ink quantity is detected by detecting deviation of a deviation member; this deviation occurs upon a change in pressure in an ink supply path in the ink supply system. The detection is performed after a predetermined time delay with respect to a signal relating to a change of scan direction or with respect to operation of a pump.
