Filed: 1988-10-21
Abstract: PURPOSE:To prevent the damage of a tape edge part by properly selecting the inclination of a drum device and approximately equalizing the height of a tape from a cassette reference face at a tape entrance point and that at a tape releasing point. CONSTITUTION:A rotating drum device 1 is provided with a guiding face 1a, which controls the running position of a magnetic tape 7, to determine the height of the tape 7. Consequently, the height of the tape 7 from a reference face 1a of a cassette 2 is determined by the inclination of the device 1. The inclination of the device 1 is so selected that a height H1 from the reference face 2a of the tape 7 wound at about 180 deg.C around the device 1 at a tape entrance point A and a height H2 from the reference face 2a of the tape at a tape releasing point B are approximately equal to each other. Thus, the tape height on the drum 1 is less changed to reduced the variance in height of the guide face 1a of the drum. Consequently, the damage of the edge part of the magnetic tape is prevented.

Filed: 1995-10-12
Abstract: PROBLEM TO BE SOLVED: To perform high-speed switching response by amplifying the on/off threshold current of a light receiving element at a front step and rear step mirror circuits and outputting the amplified on/off signal from a constant current circuit. SOLUTION: An idling constant current circuit 60 outputs constant current Io of several μA, which is about the same as the threshold current Iref of a light receiving diode PD. An idling current circuit 40 is composed of transistors TrQ41 Q43 . The idling current I41 , which is to be subtracted from the collector of the TrQ41 by the TrQ42 , is about the same as the threshold current, since the idling current I41 is the same as the idling constant current Io , and the idling current I42 , which is to be subtracted from the collector of the TrQ12 by the TrQ43 , is the value obtained by amplifying the idling constant current Io at the front step mirror circuit 10.  At the rear-step mirror 20, the value obtained by amplifying the current I41 at the front-step mirror circuit 10 and the current I42 are offset, and the influence of the idling circuit 40 is eliminated on the output current of the constant current circuit 30. Thus, high-speed switching is allowed.
