Abstract
Abstract A cassette tape recording and/or reproducing apparatus has a pair of movable reel tables (2,8), the center distance between which is automatically so adjustable as to coincide with the center distance between reels of any one of a number of optionally selected types of tape cassette to be loaded in the apparatus having different distances between their reel centres.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
122 words
A cassette tape reconding and/or reproducing apparatus capable of mounting optionally any one of a number of types of tape cassette having different distances between the centres of their reels, the apparatus being characterised in that it comprises: a pair of reel tables (28) capable of engaging with and driving said pair of reels (2,8), respectively; detecting means (22,23) to discriminate the type of tape cassette when the tape cassette is to be mounted; and means for moving said pair of reel tables to adjust the center distance therebetween with the results obtained from said detecting means, thereby the center distance between said pair of reel tables being adjusted in accordance with any mounted one of said various types of hape cassette.
Claim 2
Dependent Claim
122 words
A cassette tape reconding and/or reproducing apparatus capable of mounting optionally any one of a number of types of tape cassette having different distances between the centres of their reels, the apparatus being characterised in that it comprises: a pair of reel tables (28) capable of engaging with and driving said pair of reels (2,8), respectively; detecting means (22,23) to discriminate the type of tape cassette when the tape cassette is to be mounted; and means for moving said pair of reel tables to adjust the center distance therebetween with the results obtained from said detecting means, thereby the center distance between said pair of reel tables being adjusted in accordance with any mounted one of said various types of hape cassette.
Claim 3
Dependent Claim
22 words
Apparatus according to claim 1 wherein said pair of reel tables are directly driven with a pair of reel motore (30), respectively.
Claim 4
Dependent Claim
55 words
Apparatus according to claim 2 wherein said pair of reel tables having respectively said pair of reel mtors are slidably mounted on a respective pair of guide rails (32, 33) and moved linearly together with said pair of reel motors (30) by said means for adjusting the center distance between said pair of reel tables.
Claim 5
Dependent Claim
63 words
Apparatus according to claim 3 wherein said pair of guide rails capable of guiding said pair of reel tables are so arranged as to be symmetrically inclined relative to each other and said pair of reel tables are arranged to be synchronously moved along said pair of guide rails through said means for adjusting the center distance between said pair of reel tables.
Claim 6
Dependent Claim
79 words
Apparatus according to claim 4 wherein each of said pair of guide rails comprises a pair of guide shafts (32,33) parallel to each other, each of a pair of sliding supports (29) is slidably movable along said pair of guide rails comprising said guide shafts, each of said pair of reel motors is mounted in said sliding support, and each of said reel tables is secured to the upper end of a motor shaft (31) of said reel motor.
Claim 7
Dependent Claim
62 words
Apparatus according to any one of the preceding claims wherein said detecting means to discriminate the type of tape cassette comprises a plurality of sensors, and said means for adjusting the center distance between said reel tables is controlled on the basis of the output from said sensors so as to adjust automatically the center distance between said pair of reel tables.
Claim 8
Dependent Claim
70 words
Apparatus according to claim 5 or claim 6 wherein a pair of space adjustors between reel tables means for moving adjustably said pair of sliding supports and a motor for driving synchronously said pair of space adjustors between reel tables are provided, and said motor is controlled on the basis of the output from said sensors so as to adjust automatically the center distance between said pair of reel tables.
