摘要： In a tape cassette having sensor optical path holes provided on respective wall portions on a straight line coupling a position of a light emission element with a position of a light reception element so that light from the light emission element is introduced into a tape container and light passing through a tape running path of the tape container comes out of the tape container and reaches a light reception element, a light shielding member having a light shielding effect is bonded around a sensor optical path hole right after the light from the light emission element comes out of the tape container.

摘要： A tape cassette has a cassette case with top face, under face, front face, rear face, and a pair of right and left side face portions. A pair of supply and take-up tape containers sides is provided in the cassette case. A tape is wound around a pair of reels and contained in the pair of tape containers. A first wall portion connects the rear and right side face portion with each other and forms part of the take-up side tape container. A second wall portion connects the rear and left side face portion with each other and forms part of the supply side tape container. A first prism portion extends from the rear face portion to the right side face portion and refracts or reflects light from a light emission element of a recording and reproducing apparatus for detecting presence and absence of the tape cassette.

摘要： The present invention discloses a tape cassette having a front lid for protecting a magnetic face of a magnetic tape accommodated in a casing made of upper and lower half members against dust or the like, and a connecting plate and a rear lid suspended from the connecting plate for protecting an upper portion and a lower portion of the rear face of the magnetic tape respectively. The front lid is rotatably supported at sides of the casing. The rear lid is rotatably suspended on the connecting plate which is rotatably supported on the front lid. The magnetic tape is protected between the front lid and the rear lids together with the connecting plate in a lid closed state. A pair of pins provided on the rear lid are snugly fitted in a pair of guide grooves formed in protruding portions provided in the lower half member so that the rear lid may move in opening and closing directions. The guide grooves have open tops so that the pins of the rear lid are easily inserted into the guide grooves in the assembly process. The open tops are covered with front rims provided on the upper half member in the assembly process.
摘要翻译： 本发明公开了一种磁带盒，其具有用于保护容纳在由上下半部件构成的壳体中的磁带的磁性面的防尘盖等的前盖，以及从连接板悬挂的连接板和后盖 用于分别保护磁带背面的上部和下部。 前盖可旋转地支撑在壳体的侧面。 后盖可旋转地悬挂在可旋转地支撑在前盖上的连接板上。 磁带在盖子和后盖之间被保护，连接板处于盖子关闭状态。 设置在后盖上的一对销钉紧密地装配在形成在下半部件中的突出部分中的一对引导槽中，使得后盖可以在打开和关闭方向上移动。 引导槽具有开口顶部，使得后盖的销在组装过程中容易地插入导向槽中。 打开的顶部在组装过程中被覆盖有设置在上半部件上的前轮缘。

摘要： A magnetic tape cassette for use in an apparatus having a light source and a light sensor (5a, 5b) for detecting a tape end by the difference of light transmittance of a tape. The magnetic tape cassette (1) is composed of a cassette housing for having a transparent or semi-transparent upper half (1b) and a lower half (1a), and the reel being connected with the tape, and a light exit (7A, 7B) being opposed to the light sensor (5a, 5b) when the tape cassette is loaded to a predetermined position in the apparatus, for passing light from the light source to the light sensor through the light exit, wherein a light path (4a, 4b) of the light emitted from the light source crosses a travel path of the tape, a light-shielding member (2a, 2b) for limiting the light emitted from the light source, placed contiguous to the light exit, and a rib (81, 83) being formed in the upper half and the lower half (1a, 1b) wherein a plurality of triangular shaped prisms (83a) is formed serially on at least one side of the rib (83).
