Tape cleaning apparatus having a cleaning blade contacted with the tape only when the associated tape recording and/or reproducing apparatus drives the tape at a normal speed
Abstract A tape cleaning apparatus for a tape recording and/or reproducing apparatus prevents possible dropping of recording or a possible dropout during recording and/or reproducing operation of a tape while the tape is fed at a low speed and can protect the tape when the tape is fed at a high speed to effect fast feeding or rewinding thereof. The tape cleaning apparatus comprises a blade made of an abrasion resistant material and located on the upstream side of a recording and/or reproducing section of the tape recording and/or reproducing apparatus in a direction in which the tape is fed at the low speed. The tape cleaning apparatus also includes a controller for controlling the blade to assume a first position at which the blade contacts with the tape to remove foreign substance sticking to the tape when the tape is fed at the low speed but to assume a second position at which the blade is spaced apart from the tape when the tape is driven at a high speed.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
164 words
A tape cleaning apparatus for use with a tape recording and/or reproducing apparatus which has a first mode in which a tape from a tape cassette removably loaded in position is fed at a first speed while transducer means records and/or reproduces signals on the tape and a second mode in which the tape is driven at a second speed higher than the first speed, comprising: a blade member made of an abrasion resisting material and located at an upstream side of said transducer means with respect to a direction in which the tape is fed at the first speed; and control means for controlling said blade member to assume a first position at which said blade member contacts the tape to remove foreign substance sticking to the tape when the tape is fed at the first speed but to assume a second position at which said blade member is spaced apart from the tape when the tape is driven at the second speed.
Claim 2
Dependent Claim
164 words
A tape cleaning apparatus for use with a tape recording and/or reproducing apparatus which has a first mode in which a tape from a tape cassette removably loaded in position is fed at a first speed while transducer means records and/or reproduces signals on the tape and a second mode in which the tape is driven at a second speed higher than the first speed, comprising: a blade member made of an abrasion resisting material and located at an upstream side of said transducer means with respect to a direction in which the tape is fed at the first speed; and control means for controlling said blade member to assume a first position at which said blade member contacts the tape to remove foreign substance sticking to the tape when the tape is fed at the first speed but to assume a second position at which said blade member is spaced apart from the tape when the tape is driven at the second speed.
Claim 3
Dependent Claim
23 words
A tape cleaning apparatus according to claim 1, wherein said blade member has first and second sharp edge portions on opposite sides thereof.
Claim 4
Dependent Claim
25 words
A tape cleaning apparatus according to claim 1, wherein said blade member has at least one sharp edge portion, and is secured on holder means.
Claim 5
Dependent Claim
17 words
A tape cleaning apparatus according to claim 3, wherein said blade member is of a non-magnetic material.
Claim 6
Dependent Claim
47 words
A tape cleaning apparatus according to claim 4, wherein said control means includes a pivotal lever member having said holder means mounted thereon, and plunger means for actuating said pivotal lever member upon changing between the first and second modes of said tape recording and/or reproducing apparatus.
