A moving object detection device has a magnetic sensor element, a permanent magnet for applying a magnetic field to the magnetic sensor element; a board on which electronic parts are mounted, a holder; and a case. The holder has an integral approximately box-shaped support part to hold the magnet and the board, and the holder is inserted into the case so that the magnetic sensor element, the permanent magnet, and the board are contained in the case. The holder and the case are fitted and fastened to each other by concave-convex-shaped elements.

Moving object detection device

A tape cassette including a housing of two sections joined with a magnetic tape inside has in its front wall a center opening for magnetic head and two openings for capstan insertion, each housing section having a U-shaped guide joined to a partition behind one capstan opening. In each housing section the U-shaped guide has a pair of guide ribs formed on the opening side and having a height greater than the tape width, and a wall supporting the rear portions of the guide ribs and partitions formed at the rear of the center opening and the other opening are all formed to a height about half that of the guide ribs.

Video cassette cartridge construction

In a case for holding a magnetic tape cassette comprising a lid and an inner enclosure formed of a planar bottom wall portion having a pair of spool stops projecting inwardly from its inner side and edge walls formed along the periphery of the bottom portion excepting a part of it and extending perpendicularly to that portion, one of the edge walls being formed with a thumb recess, the inner enclosure is made by a mold with a gate inlet so that the bottom portion has a gate mark on its outer side at a point where that portion meets the edge wall formed with the thumb recess, at a right angle to it, and underneath the recess. The planar bottom portion and peripheral edge walls are molded together in one piece. The gate mark is located at the point on an extension of a line intersecting the midpoint of a straight line that connects the two spool stops, on the outer side of the planar bottom portion, and extending at right angles to the straight line.

Molded magnetic tape cassette case having improved gate mark location

A hub of a tape cassette comprising a generally circular outer ring portion (6), an inner ring portion (8) concentric with the outer portion and a generally annular rib (10) connecting the outer and inner ring portions, wherein said annular rib is formed so that its wall thickness increases continuously from a position (A) adjacent to a gate portion (G) for injection molding towards a portion (B) most apart from the gate portion, along the circumferential direction.
