Claims
- 1. An information signal recording and/or reproducing apparatus for recording and/or reproducing an information signal on or from a tape-shaped record bearing medium wound around a pair of reels by allowing the record bearing medium to travel in a longitudinal direction thereof, said information signal recording and/or reproducing apparatus comprising:
- (a) detecting means for detecting a rotating speed of at least one of said pair of reels to produce a first information;
- (b) computing means for computing an amount of a portion of said tape-shaped record bearing medium wound on one of said pair of reels based on said first information to produce a second information;
- (c) display means for making a display in response to said second information; and
- (d) changing means for changing a display step of said second information by said display means on the basis of said first information.
- 2. An apparatus according to claim 1, wherein said changing means includes a generation circuit for generating an indication information indicative of said display step, and a changing circuit for changing said indication information based on said second information.
- 3. An apparatus according to claim 2, wherein said changing means further includes a sample-and-hold circuit arranged to sample-and-hold said second information, and a determining circuit arranged to determine timing for sample by said sampling-and-hold circuit on the basis of said indication information.
- 4. An apparatus according to claim 3, wherein said determining circuit includes an adder arranged to add said indication information on an output information of said sample-and-hold circuit, and a comparator arranged to compare said second information with an output information of said adder.
- 5. An information signal recording and/or reproducing apparatus for recording and/or reproducing an information signal on or from a tape-shaped record bearing medium wound around a pair of reels by allowing the taped-shaped record bearing medium to travel in a longitudinal direction thereof, said information signal recording and/or reproducing apparatus comprising:
- (a) detecting means for detecting a rotating speed of at least one of said pair of reels to produce a first information;
- (b) computing means for computing an amount of a portion of said tape-shaped record bearing medium wound on one of said pair of reels based on said first information to produce a second information;
- (c) quantization means for quantizing said second information to produce a quantized information;
- (d) display means for making a display based on the quantized information; and
- (e) changing means for changing a step of the quantization of said quantization means based on said first information.
- 6. An apparatus according to claim 5, wherein said quantiziation means includes a generation circuit for generating an indication information indicative of the step of quantization, and said changing means is arranged to change said indication information based on said second information.
- 7. An apparatus according to claim 6, wherein said quantization means further includes a sample-and-hold circuit arranged to sample-and-hold said second information, and a determining circuit arranged to determine timing for sampling by said sample-and-hold circuit on the basis of said indication information.
- 8. An apparatus according to claim 7, wherein said determining circuit includes an adder arranged to add said indication information on an output information of said sample-and-hold circuit, and a comparator arranged to compare said second information with an output information of said adder.
- 9. An information signal recording and/or reproducing apparatus for recording and/or reproducing an information signal on or from a tape-shaped record bearing medium wound around a pair of reels by allowing the tape-shaped record bearing medium to travel in a longitudinal direction thereof, said information signal recording and/or reproducing apparatus comprising:
- (a) detecting means for detecting a rotating speed of at least one of said pair of reels to produce a first information;
- (b) computing means for computing an amount of a portion of said tape-shaped record bearing medium wound on one of said pair of reels based on said first information to produce a second information;
- (c) display means for making a display in response to said second information; and
- (d) inhibiting means for inhibiting a renewing of the display of said display means when said second information changes in a predetermined direction related to a direction in which said tape-shaped record bearing medium travels.
- 10. An information signal recording and/or reproducing apparatus for recording and/or reproducing an information signal on or from a tape-shaped record bearing medium wound around a pair of reels by allowing the tape-shaped record bearing medium to travel in a longitudinal direction thereof, said information signal recording and/or reproducing apparatus comprising:
- (a) detecting means for detecting a rotating speed of at least one of said pair of reels to produce a first information;
- (b) computing means for computing an amount of a portion of said tape-shaped record bearing medium wound on one of said pair of reels based on said first information to produce a second information;
- (c) sampling means for sampling said second information to produce a sampled information;
- (d) determining means for determining timing for sampling by said sampling means in response to said second information; and
- (e) display means for making a display on the basis of said sampled information.
- 11. An apparatus according to claim 10, wherein said determining means includes an addition circuit which is arranged to add a predetermined value on said sampled information; a comparison circuit which is arranged to compare said second information with an output information of said addition circuit; and a circuit arranged to form sampling pulses for said sampling means on the basis of an output of said comparison circuit.
