Jog device for magnetic recording and reproducing apparatus

A jog device for a magnetic recording and reproducing apparatus, comprising:

• tape supply and tape take-up reel assemblies for winding a magnetic tape;
• a rotating gear portion selectively engaged with said tape supply and tape take-up reel assemblies, respectively, having a clutch mechanism including respective clutch gears for transmitting a driving force of a capstan motor to said reel assemblies directly or by a clutch force by a slip;
• and
• rotating means for rotating said clutch mechanism of said rotating gear portion by a clutch force, due to slip from an additional driving source, thereby rotating said reel assemblies by a clutch force due to slip upon mode conversion, said rotating means including a clutch gear rotating unit, said unit being temporarily rotated during mode conversion so as to rotate said respective clutch gear of said tape supply reel clutch, said clutch gear rotating unit including a jog lever;
• a gear lever cooperating with said jog lever for selectively rotating said clutch gear of said tape supply reel clutch;
• a drive member for driving said clutch gear rotating unit during said mode conversion;
• and a returning unit for returning said clutch gear rotating unit during said mode conversion to a normal-direction reproducing mode state of said clutch gear rotating unit.
