Operating mode change-over apparatus in tape recording and/or reproducing apparatus

An operating mode change-over mechanism for use in a tape recording and/or reproducing apparatus comprising:

• at least one plunger-solenoid having a stationary iron core and a movable iron core.
• said movable iron core movable from a first position in contact with said stationary iron core to a second position spaced from said stationary iron core,
• a drive motor,
• a pinion driven by said drive motor,
• a rack member movable from a first position in engagement with said pinion to a second position disengaged from said rack,
• operating mode change-over means driven by said rack from a first inoperative position to a second mode change initiating position when said rack is in said first position,
• locking means driven by said movable iron core to hold said rack in said first position when said movable iron core is in its said first position, and
• spring means to urge said movable iron core into its said first position against said stationary iron core whereby while said movable iron core is in its said first position said plunger-solenoid is energized and said drive motor is driven.
