摘要： A slide type cassette loading apparatus includes a loading section (20) for receiving a tape cassette (31) to move the same between an inlet/outlet position and a reference position for loading, and a movable chassis (3) for sliding the cassette, located in the reference position, to a recording/reproducing position while carrying the cassette on the movable chassis. The loading section (20) is of a double structure type which has an outer cassette holder (5) pivotable relative to the movable chassis (3) and an inner cassette holder (4) supported to the outer cassette holder (5). The inner cassette holder (4) is mounted on the outer cassette holder (5) so as to make a pivotal movement together with the outer cassette holder (5) and be movable in slide directions of the cassette (31), and is operatively coupled to the movable chassis (3) so as to be movable together with the movable chassis (3).

摘要： A tape running guide and tape loading mechanism for magnetic tape recording and reproducing device allows a cylinder drum carrying magnetic heads to minimize its size by employing a three-dimensional loading system is employed in which a level of tape fed to a cylinder drum is made high and that of the tape leaving the cylinder drum is made low. A tape guide system includes, in the tape supply side, at least a first, movable slanted pin and a first, movable tape height regulation guide roller for deriving the tape from an open space of a magnetic tape cassette and winding the tape on the cylinder drum, a second slanted pin and a second tape height regulation guide roller and a third, movable guide pin for winding the tape on the second slanted pin are provided and, in the tape returning side, a fourth, movable slanted pin and a fourth, movable tape height regulation guide roller for deriving the magnetic tape from the open space of the tape cassette and winding the magnetic tape on the cylinder drum, a fifth, movable slanted pin and a pinch roller which are to be derived from the open space of the tape cassette and a capstan arranged outside the open space. These movable tape guide members are movable on a common area in time-shared manner to thereby make the loading mechanism compact.

摘要： PROBLEM TO BE SOLVED: To simplify the constitution and to reduce the number of constituent parts to reduce the cost by bending a metallic holder base to form a side holder part on one side of a cassette holder and integrally forming a boss part by drawing work. SOLUTION: A cassette holder 40 consists of a metallic base 41, which has one side end part bent and stood into an approximate L shape to integrally form a side holder part 41a, and a side holder part 42 which is connected to the other side end part and is stood and is formed with resin. Boss parts 41b and 41c are integrally projected from the outer side face of the side holder part 41a by drawing. With respect to the side holder part 42, projecting boss parts 42a and 42b and a rather longer projecting canopy top part 42c which is used to retain the upper side of one end of the cassette are formed on the outer side face, and a cassette retaining spring 43 is provided on the inside. Thus, the constitution is simplified, and the man-hour of assembling is reduced.

摘要： PURPOSE:To obtain stabilization in a tape travelling by providing a discoid metallic weight, which is integrated in the revolving part of a roller guide and has a larger diameter than that of the roller, and allowing the adjustment of a height in the direction of a tape width. CONSTITUTION:An axis 7a is implanted on an arm 23 at a prescribed inclination and inclined direction. This device is provided with a conical compressed spring 7b, a flange 7c regulating the lower end of the tape 7d, and the weight 7e which is pressed in a resin roller 7f and integrated with 7f and the sleeve 7d capable of turning around the sleeve 7d while integrated with the roller 7f; assembled with a spacer 7g and a stopper 7h for the sleeve 7d and the roller 7f; and engaged with the threaded part of the axis 7a. The flange 7c and the sleeve 7d are energized with a spring 7b to the direction of an arrow E, moved to the direction of either the arrow E or F at the position of the stopper 7h, and the roller 7f and the weight 7e are also moved to the directions of the arrows attending on the movement of the flange 7c. Thus, the regulation and the adjustment of the height at the lower end of the magnetic tape 1 are attained and the travelling of the tape is stabilized.

摘要： PURPOSE:To make a magnetic recording and reproducing device small in size and light in weight by arranging a guide roller on an arm and guiding only one guide post group by the use of a guiding groove member by a link mechanism. CONSTITUTION:The guide roller 73 (one of the guide post group 910 on an incoming side) is arranged on an 1GR3 arm 7 and only the one guide post group 910 is constituted so as to be guided by the use of the guide groove member by the link mechanism. And the arm 7 having the roller 73 and a tension arm 6 are coaxially arranged. Thus, the reduction of press-contact force among the guide post group driven by the link mechanism does not occur and also the number of the guiding groove member does not increase, so that the subject device can be made small in size and light in weight.

摘要： PURPOSE:To provide a detection switch attaching structure making it possible to provide a device dealing with a thin type. CONSTITUTION:This structure is constituted of a switch 12 for detecting operations and a switch attaching hole 1d provided on the chassis 1 of the device and the switch 12 is attached to a chassis hole 1a by superposing the thickness of the chassis 1 on that of the switch 12 in the condition that the switch main body is not protruded from the lower surface of the chassis 1. As the detecting switch is attached to the switch attaching hole provided on the chassis of this device by superposing the thickness of the chassis and that of the switch, the thickness of the detecting switch is apparently reduced as much as the one equivalent to the superposed amount.
