Abstract: An input video signal is written into alternate field memories M1 and M2, according to a timing clock from an input video clock generator. A display video signal is alternately read from those field memories, according to a timing clock from a display video clock generator. In switching a read memory, an address observation circuit judges whether or not a read/write address passes by a write/read address, referring to the condition of reading and writing operations. In this event, the circuit makes a judgement, based on the lag between a vertical synchronizing signals of an input video signal and of a display video signal, and a change of the lag with time. If it is judged that one address will pass by the other, the same read/write memory is again accessed for reading/writing. With this arrangement, there is provided a circuit having a relatively simple structure for preventing a match of read and write addresses.

The sorter trays includes a first detection lever that is rotated by the weight of recording sheets and a second detection lever that rotates in association with the first detection lever. A lever detector is provided on the sorter guide to detect the movement of the second detection lever. The sorter or guide is also provided with a sheet detection lever to detect a jam in the sorter guide.

Abstract: A printer with a sorter unit allows printed recording sheets to be sorted to a single tray selected from a plurality of trays by a recording sheet guide mechanism that pivots around a shaft. Thus, the printer can sort the printed sheets by page, by user, or discharge the printed sheets paginated or with the printed side facing upward. The recording sheet guide mechanism is constructed to pivot around the shaft so that only a single drive unit is employed to select a tray for sorting. Thus, the printer has a simple and small structure. The printer has a recording sheet discharge outlet with discharge rollers for discharging a recording sheet that has been printed by the electrophotographic process.

The apparatus further comprises a sheet switching guide mechanism by which the head end of the sheet is switched to both upper and lower directions. When the sheet switching guide mechanism is set to the upper direction, the printed sheet is forwarded by a sheet guide member to thereby pass through the printing path the sheet has already been through with the rear side of the sheet being the front, and the printing data is written from the last line during this process.
