Abstract
A teaching system utilizing prerecorded tape which is prepared in sectors with a message segment and position indicators in the form of transparent windows which are photoelectrically detected. After a message or question is played, a first window is detected by a first detector and the tape drive motor is deenergized with another window positioned before one of a plurality of other detectors. The operator then attempts to answer or identify the message by making a selection corresponding to one of the plurality of detectors, and if a correct answer is given, a signal is given to the operator. All of the photoelectric detecting devices are on a carrier which is removably mounted to a cassette.
Claims9
An educational system comprising a prerecorded tape and a tape player including a drive motor for driving said tape and a playback head,
- said tape including at least one sector which has a message recorded thereon and two windows for passing light through the tape, said message sector and said windows being at predetermined distances from each other,
- first means photoelectric detecting means positioned along the path of the tape for photoelectrically detecting one of said windows and deenergizing said drive motor,
- a plurality of other photoelectric detecting means positioned along the path of said tape, the position of said second window in said tape being selected such that said second window is adjacent one of said other detecting means when said one of said windows is detected by said second detecting means, and
- a plurality of operator selection means, each corresponding to one of said other detecting means, the recorded message posing a question or choice of selection to the operator, and means for indicating that operation of one of said selection means corresponds to said detecting means adjacent said second window,
- said tape being in a cassette, said photoelectric detecting means being mounted on a removable carrier which may be fitted to said cassette with said photoelectric detecting means positioned to detect said windows in said tape.
An educational system including a prerecorded tape and a tape player including a drive motor for driving said tape and a playback head,
- said tape including at least one sector which has a message recorded thereon and two windows for passing light through the tape, said message sector and said windows being at predetermined distances from each other,
- first means photoelectric detecting means positioned along the path of the tape for photoelectrically detecting one of said windows and deenergizing said drive motor a predetermined time after the recorded message has passed said head,
- second photoelectric detecting means positioned along the path of the tape for detecting said one window after said predetermined time and providing a signal which holds said motor in a deenergized state,
- a plurality of other photoelectric detecting means positioned along the path of said tape, the position of said second window in said tape being selected such that said second window is adjacent one of said other detecting means when said one of said windows is detected by said second detecting means, and
- a plurality of operator selection means, each corresponding to one of said other detecting means, the recorded message posing a question or choice of selection to the operator, and means for indicating that operation of one of said selection means corresponds to said detecting means adjacent said second window.
