@ Input Circuit
1.
Types of inputs
1-1. Mode select button inputs
A total of 8 input ports are available for accepting
these inputs.
When these buttons are pressed, the cor-
responding input ports are high in potential.
1-2. Sensor inputs
These inputs are sent from the sensors supporting the
protection
functions
of this VTR
that
protect
the
loaded
tape or the machine
against possible damage
due
to a change
in operating conditions or environ-
ment or due to misoperation
or malfunction
of each
mechanism.
Input ports to accept
these inputs are
3 in total.
These input ports are high in potential whenever the
