ABSTRACT:
A tape recorder comprises a rotary type tape speed control means which has a control shaft to increase the running speed of a magnetic tape when it is rotated in one direction and to decrease the same when it is rotated in the other direction, a rotary type tone adjusting means which has an adjusting shaft to lower a high frequency response of sound reproduced from the tape when it is rotated in one direction and to elevate the same when it is rotated in the other direction and a control mechanism mechanically coupled to the speed control means and the tone adjusting means. The control mechanism comprises a spur gear secured to the control shaft and a spur gear secured to the adjusting shaft and a spur gear engaged with the both spur gears to cause the adjusting shaft to rotate in one direction when the control shaft is rotated in one direction and to rotate in the other direction when the control shaft is rotated in the other direction.
