摘要： A reel brake device for a tape reel of a magnetic tape cassette has a pair of braking strips for a supply reel and a take-up reel. The braking strips are formed with at least one hinged section to allow resilient deformation in order to absorb kinematic energy exerted on the braking strips from the tape reel as the reel is subjected to rotational torque or lateral force. By providing the capability of resilient deformation for the braking strips, braking engagement can be maintained even when vibration exerting rotational force is applied to the tape reels.

摘要： A tape reel for a magnetic tape cassette can accurately hold upper and lower reel flanges parallel to each other. The tape reel for a magnetic tape cassette comprises a reel hub assembly including a first reel flange and a cylindrical reel hub integral with the first reel flange and extending from the center of the first flange. The cylindrical reel hub has a support surface at the end remote from the first reel flange onto which to mount a second reel flange. A fastener and a second reel support projection are formed on the support surface of the reel hub. The fastener fastens the second reel flange on the support surface. The second reel support projection is formed on the support surface. The second reel flange support projection has a plane opposing the second reel flange accurately parallel to the first reel flange. Since the area of the second reel support projection is substantially smaller than that of the support surface of the reel hub, it is possible to hold the face opposing the second reel flange accurately parallel to the first flange. Therefore, the second reel flange supported by the second reel flange support projection can be accurately held parallel to the first reel flange.

摘要： A magnetic tape cassette is provided with a pivotal closure lid pivotably secured to opposite edges of a casing for movement between a closed position, in which the front opening of the casing through which a magnetic tape can be extracted for loading onto a rotary head while not in use, and an open position wherein the closure lid is pivoted away from said opening to allow access to the tape while in use, is also provided with a sliding closure member slidably mounted on one face of the casing and cooperative with the aforementioned pivotal closure lid, which sliding closure member is held either in a closed position while the pivotal closure lid is in its closed position to cover a bottom spacing through while a device constituting part of a tape handling mechanism may be inserted, or an open position while the pivotal closure lid is in its open position to allow the aforementioned device of the tape handling mechanism to engage the casing through the bottom spacing for extracting the tape for loading onto the rotary head, and is retained at least in the closed by means of a locking mechanism. The locking mechanism comprises a pair of locking members provided adjacent both lateral sides of the magnetic tape cassette and are associated with the cassette casing. The pair of locking members are adapted to resiliently establish locking engagement with the sliding closure member at locations adjacent both lateral sides of the magnetic tape cassette.
