    摘要: In a frame transfer method and device by which an address space of a shared buffer can be effectively utilized without a reduction of the space even if an abnormal operation occurs in a management of the shared buffer, after frame data is written in the shared buffer during one monitor cycle when the frame data is to be read without fail from the shared buffer, an address space where the frame data has not been read from the shared buffer is detected during a next monitor cycle, and an address space where not a read but a write of the frame data has been performed at least during the monitor cycle is detected. In the next monitor cycle, the address space is released as a free address of the shared buffer.

    摘要: A control mechanism of an automatic document feeder for an electrophotographic copying machine is provided with a plurality of document discharge trays and a selecting device to select one of the document discharge trays to receive a document which has been processed and discharged. The control mechanism generally selects a specified one of the document discharge trays when documents are set on a supply tray and transported sequentially by the feeder. Only while the first of these documents is being transported from the supply tray into a processing position, however, the control mechanism selects a tray other than the specified one such that a document which may have been left inadvertently in the feeder by the previous user does not become mixed with the documents which are discharged subsequently.

There is provided a burst address producing circuit 8 capable of producing two burst address signals in one test period, which comprises a clock-repetition-rate doubling circuit 15 for outputting a clock at twice the pulse repetition rate of the test period signal TI, a first multiplexer 16 for selecting either one of the clock TI and the rate-doubled clock from the circuit 15, and a burst address generating circuit for generating an address signal to be supplied to the failure analysis memory 5. The burst address generating circuit outputs two burst address signals in one test period by computing operation using an address signal first supplied from the pattern generator 2, in the case that a memory under test operates in burst mode and adopts double data rate system, and supplies them to the failure memory as burst address signals.
