IPC: G11B5/596
Filed: 1989-01-26
Abstract: PURPOSE:To eliminate the magnetical and electrical influences of the writing current of a data head on a servo head by simple means by controlling the writing current value of the data head in accordance with the distance from the servo head. CONSTITUTION:A write driver 3 converts write data 5 to the inversion current of the current value determined by a writing current setting circuit 4 and supplies the same to a head selecting circuit 2 at the time of data writing. The head is selected by the circuit 2 and the writing current is caused to flow. The writing current value for each of the heads set in this circuit 4 is so set as to decrease the current for the data heads nearer the servo head and to increase the current as the heads are parted from the servo head. The writing current of the magnitude corresponding to the head selected by a head select signal is transmitted to the driver 3. The magnetical and electrical influences of the writing current on the servo head is eliminated in this way by the simple means.

Inventor: KOMADA KENYA
IPC: H04N1/29
Filed: 1981-02-04
Abstract: PURPOSE:To secure the sequence properties of the stock in a normal mode to facilitate an easy after-process and to perform a quick discharge of paper in an emergency, by providing the 1st tray to which the discharge of paper is carried out via an inverting device plus the 2nd tray to which the discharge of paper is carried out directly when the inverting device is not working. CONSTITUTION:After the rear edge of an inverted paper 9 passes through a switch guide plate 17, the plate 17 goes down to turn on a microswitch 18. Thus an inverting device is driven to invert an inverting roller 16. As a result the recording paper 9 held by the roller 16 is sent to a conveying roller 20 at the rear edge side of the paper 9 to be discharged onto the 1st paper discharge tray 24. the paper 9 discharged on the tray 24 is stoked in good order as if which image side turned down. When an emergency signal is supplied, the switch 18 is turned off. Then the inverting device doesn't function, and a reversing device 23 is put into no operation state. Thus the paper 9 is discharged onto the 2nd paper discharge tray 25 by the roller 16. Accordingly, the time required to pass through the device 23 is eliminated to ensure the discharge of paper directly to the tray 25.
