For something which doesn't have complicated or high density circuit boards, the schematic wouldn't be as complicated and can be printed easily and pasted inside or in the manual.
Back in the day, the electric/electronic stuff I opened up which did not have the schematic diagram inside, were devices like tape recorders, radios, video game consoles, etc ...
Looking at the circuit board layouts, such a schematic diagram would be very complicated.
