Abstract

PURPOSE: To improve operability, to prevent malfunction, and to reduce cost, by changing speeds and sizes with a single operation switch.
CONSTITUTION: The output of an operation switch 1 for setting the turning speed of a phonomotor M and the size of a record disk is inputted as shift pulses to a register 3 through a chattering absorbing circuit 2. An OR gate 8 which inputs outputs A and B of the register 3 generates a high-level output for 30cm record size, and an OR gate 9 which inputs outputs C and D also generates a high-level output for 17cm size. Then, an AND gate 11 generates a high-level output for 30cm size and when a tone arm is led to the play start position of a 30cm record disk; and an AND gate 12 generates a high-level output for 17cm size only when the tone arm is led to the play start position of a 17cm record disk. The outputs of the gates 11 and 12 are operated by an NOR gate 13 to generate a low-level lowering-position detection 10 signal.
