Abstract

Abstract A tape recorder has an operating mode in which a magnetic tape (T) is run at a speed higher than an ordinary reproducing speed, a magnetic head (9) is in sliding contact with the magnetic tape (T), and a desired tape position is searched for. In this operating mode, the magnetic tape (T) is run initially at a first speed higher than the ordinary reproducing speed, for example three times that speed, for a predetermined period of time after an operating switch (24, 31, 34) that sets the operating mode is turned on. Then, if the operating switch (24, 31, 34) remains continuously turned on after the elapse of this predetermined period of time, the magnetic tape (T) is run at a second spped which is higher than the first speed, for example sixteen times the ordinary reproducing speed.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 217 words
A tape recorder capable of operation at an ordinary reproducing speed and in a forward or reverse direction and comprising: a magnetic head (9) for scanning a magnetic tape (T); operating mode means (20,17, 19) for running the magnetic tape (T) at a speed higher than said ordinary reproducing speed in a state in which said magnetic head (9) is in contact with the magnetic tape (T); operating means (24) controllable by a user of the tape recorder for making said operating mode means (20,17,19) inoperative; and first speed control means (20) for controlling the operating mode means (20, 17, 19) so as to run the magnetic tape (T) at a first speed higher than said ordinary reproducing speed; characterized by: second speed control means (20) for controlling the operating mode means (20, 17, 19) so as to run the magnetic tape (T) at a second speed higher than said first speed; and automatic switching control means (20) responsive to said operating means (24, 31, 34) for making said first speed control means (20) operative for a predetermined period of time after said operating means (24, 31, 34) is operated and for making said second speed control means (20) operative when the operating means (24) is continuously operated beyond the elapse of said predetermined period of time.
Claim 2
Dependent Claim 217 words
A tape recorder capable of operation at an ordinary reproducing speed and in a forward or reverse direction and comprising: a magnetic head (9) for scanning a magnetic tape (T); operating mode means (20,17, 19) for running the magnetic tape (T) at a speed higher than said ordinary reproducing speed in a state in which said magnetic head (9) is in contact with the magnetic tape (T); operating means (24) controllable by a user of the tape recorder for making said operating mode means (20,17,19) inoperative; and first speed control means (20) for controlling the operating mode means (20, 17, 19) so as to run the magnetic tape (T) at a first speed higher than said ordinary reproducing speed; characterized by: second speed control means (20) for controlling the operating mode means (20, 17, 19) so as to run the magnetic tape (T) at a second speed higher than said first speed; and automatic switching control means (20) responsive to said operating means (24, 31, 34) for making said first speed control means (20) operative for a predetermined period of time after said operating means (24, 31, 34) is operated and for making said second speed control means (20) operative when the operating means (24) is continuously operated beyond the elapse of said predetermined period of time.
Claim 3
Dependent Claim 80 words
A tape recorder according to claim 1 wherein said automatic switching control means (20) comprises: a timer; first control means for making said first speed control means (20) operative and for starting said timer in response to the operation of said operating means (24, 31, 34); and second control means for setting said second speed control means (20) in response to said elapse of said predetermined period of time and to the operation of said operating means (24, 31, 34).
Claim 4
Dependent Claim 103 words
A tape recorder according to claim 1 or claim 2 wherein said operating means (24, 31, 34) can be made inoperative while said operating mode means (20, 17, 19) is operating at said first or second speed, and, when said operating means (24, 31, 34) is made inoperative while said operating mode means (20, 17, 19) is operating at said first or second speed, the operating mode means (20, 17, 19) is set so as to run the magnetic tape (T) at the ordinary reproducing speed in the state in which the magnetic head (9) is in contact with the magnetic tape (T).
Claim 5
Dependent Claim 91 words
A tape recorder according to claim 1 wherein said operating mode means (20, 17, 19) is a cue/review mode means comprising: reproducing mode means (20, 17) for running the magnetic tape (T) at the ordinary reproducing speed in the state in which the magnetic head (9) is in contact with the magnetic tape (T); and fast-forward or rewind mode means (20, 19) for running the magnetic tape (T) at a speed higher than said ordinary reproducing speed in a state in which said reproducing mode means (20, 17) is made operative.
Claim 6
Dependent Claim 23 words
A tape recorder according to any one of the preceding claims wherein said first speed is about three times said ordinary reproducing speed.
Claim 7
Dependent Claim 23 words
A tape recorder according to any one of the preceding claims wherein said second speed is about sixteen times said ordinary reproducing speed.
Claim 8
