第１図は、外形サイズの異なる三種類のテープカセット
ＩＡ、ＩＢ、Ｉｃｅ対応させて示す概略平面図である。In the present invention, the cassette information is included as the arrangement of holes in the plate, and the cassette information is included as a hole arrangement in the plate. By inserting a pair of sensors fixedly arranged in the cassette through the holes in the bottom of the cassette, it becomes possible to read the information contained in the plate. FIG. 3 is a schematic plan view showing three types of tape cassettes IA, IB, and Ice of different sizes in correspondence with each other.

報提供手段が配設形成されている。Each of these cassettes IA, IB, and IC has a threading area 2 facing a tape pull-out mechanism (not shown) formed in a common shape so that the cassettes IA, IB, and IC can be commonly loaded and used in the same recording/reproducing apparatus. In the present invention, a pair of tape reels 4 are formed near the center of the cassette front wall 3, which is a common position of each of the cassettes IA, IB, and IC.
A cassette information providing means as shown in FIGS. 2 to 5 is disposed in a planar triangular area 7 between A, 4B, 5A, 5B, 6A, and 6B.

必要な情報量、すなわちビット数と同じ数必要である。On the inner surface of 9B, there are diagonal cutout recesses IIA and II that extend over the upper and lower halves and are inserted and fixed (to be described later).
B extends in the vertical direction, that is, in the cassette thickness direction. Further, in this example, a retaining hole 13 into which the lower end protrusion 12 of the plate 10 is engaged is formed through the bottom surface 7A between the holes 8A and 8B. Also, 10
is a plate, which is inserted into both side edges 10A, 10Bt corresponding to the recesses 11A, 11B, so as to divide the space between the holes 8A, 8B into two. The plate 10 has narrow windows 14 arranged in the vertical direction for providing cassette information. In other words, various information about the cassette is included depending on the arrangement of the conditions 14. From the above-mentioned individual members 8A and 8B on the bottom of the cassette, there is an optical detection means 15 provided on the magnetic recording/reproducing device side and consisting of a pair of phototransistors and an optical sensor as shown in FIG. By being inserted, it is possible to read the information included in the plate 10. Note that the number of detection means 15 such as the above-mentioned seven sensors must be the same as the required amount of information, that is, the number of bits.

。In addition, to prevent reading while the cassette is down, the cassette down sensor is turned on for reading timing.
It would be better to have a system that reads it after .

すようにしてもよい。In order to make the above cassette information distinguishable from the outside of the cassette, a fifth hole is inserted into the hole 13 formed on the bottom of the half.
As shown in the figure, a method of inserting a 1G removable protrusion 12 on which a symbol 16 representing information is displayed may be used. In this case, the plate 10 may be colored to represent the information.

化することが可能である。As another example of the method of detecting information using the window 14 of the plate 10, as shown in FIG. Utilizing the fact that the speed is almost constant, it is also possible to use a bar code type that detects the H or L time interval of a rectangular wave signal as shown in FIG. 6 (6).0 [Effects of the Invention] This book With the above configuration, the information supply means is provided at a common position for each cassette of different sizes, and the magnetic recording and reproducing apparatus side, that is, the detection side, is configured to be able to handle many types of cassettes of different sizes. In addition, by arranging information in the height direction of the cassette, that is, in the thickness direction, it becomes possible to incorporate a large amount of information into a small area within the cassette. It is also possible to downsize.
