This one looks like early
piano type fonction buttons. Note the
"Compact cassette" logo on the left, this is a sign of early cassette
units as far as I know. It's the official logo of cassette tapes.
(Update) The tape have been restored and this is the new photo from it.
I've established that it was from Pre-1970 as it have a round belt, and
transistors are 1st generation of Japanese transistors. In the work, it
required to change the pinch roller as it was cracked. It's now working
well. It's low, it doesn't have any auto-stop feature.
