    摘要: For cassettes with memory for storing data relating to the cassette or the tape therein, memory error signal devices having two states representing that the cassette memory has an error or has no error, respectively, the memory error signal devices being operable between said states by a spindle member of a peripheral device. Two embodiments of memory error signal devices are disclosed, one embodiment having a capacitor, and circuit connections from said capacitor to terminals, the charged or discharged state of said capacitor constituting said two states of said device. The other embodiment has a signal plate mounted for movement between two positions, the two positions of said signal plate constituting the two states of the device, and the signal plate has terminals. The signal devices are adapted to be monitored by a peripheral device having a spindle member of unique configuration penetrating an opening in the cassette and set from a no-error to an error state by a peripheral device member having another configuration penetrating the opening. The monitoring is carried out by a monitoring circuit adapted to be connected electrically to the terminals of the signal devices.
