Filed: 1990-10-01
Abstract: PURPOSE:To facilitate high performance and expansion of the device by using a path generating means to a regular network so as to discriminate whether or not a packet is reached up to a final destination at a high speed. CONSTITUTION:The communication path decision device 2 uses a comparator circuit 13 so as to compare a value stored in a node address register 7 with an address of a node being a final destination of a communication packet at first.

IPC: G11B15/665
Filed: 1985-11-26
Abstract: PURPOSE:To prevent the damage of a tape draw-out mechanism after securing an equi-speed curve as a lift curve of a cam groove, by providing a pair of special gears which engage a drive means so that the speed of a tape draw-out means is varied between the 1st and 2nd positions within a tape cassette. CONSTITUTION:An eccentric gear 17 is unified with the 2nd loading gear 4 and a non-circular gear engaging the gear 17 is provided to a rotary member 24 which drives the gear 17. Thus the radius of the gear 17 is changed to R from (r) between a state where a magnetic tape 34 is not drawn out yet and a state where the tape 34 is drawn out even though the member 24 is revolving at the same angular speed (w). As a result, the revolving speed of the member 24 is reduced on a pitch circle. Therefore the speeds of the 1st and 2nd draw-out blocks 9 and 10 are also reduced between the 1st and 2nd positions. This reduces the abutting impacts between the blocks 9 and 10 and the stoppers 30 and 31 respectively. Thus the damage of the tape draw-out mechanism is minimized.
