This display screen turning apparatus (base for a display screen) includes a platelike base member so formed as to receive the load of a display body applied to a display screen support mechanism on a partial region and to warp in a direction opposite to the direction of deflection resulting from the load of the display body with a prescribed amount of warpage when not receiving the load of the display body, and the prescribed amount of warpage is so set that the surface of the base member is substantially flattened when the base member receives the load of the display body applied to the display screen support mechanism.

Base for display screen

This display screen turning apparatus includes a turntable mounted with a display body and rotatable in a horizontal plane, a base, rotatably holding the turntable, provided with a drawn projecting portion and a floating prevention member so mounted on the projecting portion of the base as to prevent the turntable from upward floating. The floating prevention member has a floating prevention portion provided above a region where the upper surface of the turntable is arranged, a mounting portion for mounting the floating prevention member on the projecting portion and a leg portion provided between the floating prevention portion and the mounting portion for maintaining the base and the floating prevention member at a prescribed interval by coming into contact with the base.

Display screen turning apparatus

A display screen turning apparatus capable of improving assembling workability and suppressing jolting at a time of rotation is obtained. This display screen turning apparatus includes a rotating member mounted with a display screen portion and rotatable in a horizontal plane, a base provided with an upright portion rotatably holding the rotating member and having a first hole, a regulating member so mounted on the upright portion of the base as to prevent the rotating member from moving upward, and a stop member formed in a tapered shape by end surface portions, and holding a state where the regulating member is in contact with the rotating member by inserting the stop member into the first hole of the upright portion of the base and pressing the regulating member.

This display support mechanism comprises a support shaft provided in the form of a plate, a display screen support member, having a first hole receiving the platelike support shaft, provided on the side of a display screen and a base support member, having a second hole receiving the platelike support shaft, provided on the side of a base, and at least either the first hole or the second hole receiving the platelike support shaft is provided in the form of a sector while the display screen support member is rotatable about the platelike support shaft serving as an axis of rotation in the angular range of the sector.

Display support mechanism

A display screen turning apparatus capable of improving assembling workability in assembling steps and suppressing jolting during rotation can be obtained. This display screen turning apparatus includes a rotating member mounted with a display screen and rotatable in a horizontal plane, a base, rotatably holding the rotating member, provided with an upright portion having a hole, a platelike spring of metal fitted onto the upright portion of the base for pressing the rotating member and a stop member inserted into the hole of the upright portion of the base for pressing the platelike spring and holding the platelike spring in a deflected state.

A display support mechanism allowing an easy operation of controlling the angle of a display screen with no requirement for a round shaft serving as an axis of rotation is obtained. This display support mechanism comprises a support shaft provided in the form of a plate, a display screen support member, having a first hole receiving the platelike support shaft, rotatable about the support shaft serving as an axis of rotation and a base support member having a second hole receiving the platelike support shaft, while at least either the display screen support member or the base support member is provided with a projecting portion brought into pressure contact with opposed surfaces of the display screen support member and the base support member for developing frictional resistance.

A magnetic tape apparatus has an intermediate gear ( ) meshed with an idler gear ( ) which is releasably meshed with both a pay-off reel table ( ) and a roll-up reel table ( ), a drive gear ( ) rotatably driven by a capstan motor ( ), a driven gear ( ) releasably meshed with the drive gear ( ) by way of a friction plate, a clutch mechanism ( ), and a speed increasing mechanism ( ). The speed increasing mechanism ( ) has a movable rotary body ( ) rotatably mounted around a support shaft ( ) and adapted to reciprocate along an axis of the support shaft ( ) by means of the clutch mechanism ( ). The movable rotary body ( ) is provided with a small diametered gear ( ) and a large diametered gear ( ). In a fast feed mode and a rewind mode, the small diametered gear ( ) is meshed with the drive gear ( ) while the large diametered gear ( ) is meshed with the intermediate gear ( ).

Magnetic tape apparatus

A cassette plate is provided with a bendable bottom plate, right and left side walls, and upper plates extending toward an inward direction from said side walls. The bottom plate includes a platform having a function for pushing up a backside of a tape cassette when the tape cassette is inserted into the cassette plate through a front mouth. Owing to this construction, the bottom plate convexly bends downward, and the tape cassette is kept at a distance from the bottom plate of the cassette plate. In this state, the tape cassette is supported by the platform and upper plates of the cassette plate. Therefore, this assimilates variations of the components in size, and eliminates a need of a conventional pushing spring. The constitution can decrease the number of the component in a simple construction, thereby reducing the cost in a tape cassette loading device, and a tape deck having the same.
