Abstract: The dimension in the height direction of a reel braking mechanism to be disposed on the side of an S-side reel table in a video tape recorder is made small while making it difficult to disassemble an assembled state. The dimension in an axis line direction of a pin that engages an elongated hole of a brake member of a brake arm is lengthened, thereby penetrating the brake member and extending downward. The extended portion of the pin is made to pass through a cut formed in an edge of a slide chassis.

Abstract: Each lock portion (15) has a front portion (23) including an anchoring pawl (24) and a back portion (25) extending in a direction opposite to the front portion. Therefore, when a slider (14) withdraws, each back portion comes into contact with the inside surface of a back wall (10) of a cassette shell (4) and each lock portion rotates in an unlocking direction. A bottom surface (109) defining each recess between engaging teeth (107) has a central portion which protrudes in a chevron shape. A corner of each protrusion has tapered surfaces (110?) and (110?). An anchoring pawl of each lock portion has a flat surface that comes into contact with one inclined surface (109?) of a chevron-shaped portion of any one of the recesses and one tapered surface (110?) of a protrusion disposed behind the adjacent recess.

Abstract: A cassette casing 1 has a front lid 5 on its front surface side and a shutter plate 6 retreating on the upper surface of the cassette casing 1 in the way of sliding correspondingly with the operation of the front lid 5 being open and retreated from a mouth. In order to prevent a rectangular display label 8 from being fitted on the upper surface which is the passage for movement of the shutter plate 6 of the cassette casing 1, the edge on a side opposite to the front lid 5 of the shutter plate 6 and the edge of the cassette casing against which that edge of the shutter abuts are each made into a curvilinear configuration to have thereby made the passage 9 for movement of the shutter meander.

Abstract: Disclosed is a tape cassette including a cassette shell in which tape reels around which a tape-like recording medium is wound are contained; a mouth portion provided in a front portion of the cassette shell in such a manner as to be opened forwardly, upwardly, and downwardly, the mouth portion being positioned such that part of the tape-like recording medium crosses the front end of the mouth portion; and a front lid, provided on the cassette shell, for covering the front side of the tape-like recording medium; wherein both side portions of the mouth portion of the cassette shell are taken as tape extraction portions opened forwardly; and each of the inner surfaces of outer side surface front portions of the cassette shell, which forms each of the inner surfaces of outer side walls of the tape extraction portions, is formed into a taper surface which becomes wider outwardly as nearing the front end.

Abstract: Disclosed is a tape cassette in which two positioning holes is formed in the back surface of a cassette shell. One of the two positioning holes is formed into a circular shape and the other is formed into a long-hole shape. The positioning hole formed into the long-hole shape is divided into two parts in the major direction of the long-hole. An about half of the long-hole shape is used as a positioning hole and an about remaining half thereof is used as an information detecting (ID) hole for providing various kinds of information. A removable block piece is provided on an opening portion of said ID hole. With this configuration, the ID hole can be surely provided in the tape cassette, even if the tape cassette is miniaturized.
