Claims
- 1. In an automatic reverse cassette tape recorder wherein a playback mode is set by the loading of a cassette and, after the ejection of the cassette by means of an ejection means, a new playback mode is set on a determined one side of the cassette, which comprises: a magnetic tape driving motor selectively for driving a magnetic tape in first and second running directions; an operator actuable recording mode-setting member; a pair of magnetic heads; support means for supporting said pair of magnetic heads spaced from each other; an automatic reverse circuit including an end of tape detecting means for detecting the terminal end of a tape and generating an electrical signal indicating detection of the end of the tape; means responsive to at least one of said end of tape detecting means and said recording mode-setting member for bringing one of the paired magnetic heads to a projected position suitable for contact with a magnetic tape; and cassette ejecting means for ejecting a cassette and for causing a prescribed magnetic head to be brought to said projected position only when the prescribed one of the paired magnetic heads is not in said projected position for contact with the tape, thereby always causing said prescribed magnetic head to be projected to a position suitable for contact with the tape when a cassette is ejected by said ejecting means;
- the improvement comprising:
- means responsive to operation of said recording mode-setting device for causing said driving motor to operate in only one direction to drive a magnetic tape in said one direction to permit recording on only one side of said cassette;
- means coupled to said end of tape detecting means for supplying said electrical signal to said magnetic tape driving motor for selectively automatically causing said driving motor to run the magnetic tape in the direction opposite to the previous running direction;
- an end alarm circuit coupled to said automatic reverse circuit and including a sounding device, said end alarm circuit being selectively actuated upon detection of the magnetic tape end so as to sound said sounding device;
- an automatic stop circuit coupled to said automatic reverse circuit and being selectively actuated upon detection of the magnetic tape end so as to stop the magnetic tape driving motor; and
- switch means included in said automatic reverse circuit, said switch means being coupled to said recording mode-setting device, to said automatic reverse circuit, to said end alarm circuit and to said automatic stop circuit, said switch means being always operated upon actuation of said recording mode-setting device to always disable said automatic reverse circuit and to always enable at least one of said end alarm circuit and said automatic stop circuit when the tape recorder is set in the recording mode by actuation of said recording mode-setting device, thereby permitting recording on the tape only when running in said one direction and always preventing recording on the tape when the tape runs in the reverse direction of running of the tape, and permitting playback of the tape in both of said first and second tape running directions under the control of said automatic reverse circuit when said recording mode-setting device is not actuated.
- 2. The automatic reverse tape recorder of claim 1, wherein said switch means is a normally closed switch means and which is opened upon actuation of said recording mode-setting device.
- 3. The automatic reverse tape recorder of claim 1, wherein said end alarm circuit includes means for turning off the tape recorder upon detection of said magnetic tape end only when said recording mode-setting device is actuated to place the tape recorder in the recording mode.
- 4. The automatic reverse tape recorder of claim 1, wherein said end alarm circuit sounds said sounding device only when said magnetic tape end is detected while the tape recorder is in the recording mode as a result of actuation of said recording mode-setting device.
- 5. The automatic reverse tape recorder of claim 1, wherein said switch means enables both said end alarm circuit and said automatic stop circuit upon actuation of the recording mode-setting device.
