Description

[Detailed Description of the Invention] The present invention relates to a leaf spring with a stopper.

In a tape recorder, the main chassis has a head chassis equipped with various magnetic heads.
It is provided so that it can be moved in and out, and is activated by operating a playback button or the like.

The head chassis is usually a small plate that is attached to the main chassis via a ball for smooth movement. Specifically, as shown in FIGS. 1 and 2, for example, ball receiving grooves B are formed on the main chassis A, and balls C are arranged in the grooves so as to be freely rollable. A head chassis D is placed on top of the ball, and the upper surface of the head chassis D is held down by a leaf spring E fixed to the main chassis A via a ball G, and the ball G is held against the inner surface of the active end of the leaf spring. It is supported so as to be able to roll freely in a ball receiving groove F formed in the plate, and the plate is fixed to the main chassis A by drilling a through hole I at its mounting base H and fixing it to the main chassis A with screws J.

The head chassis D mounted in this manner can be smoothly moved in and out by the ball, and is extremely comfortable. However, on the other hand, since leaf springs E are used, if an excessive shock is applied due to a fall, etc., the leaf springs will bend, causing the head and chassis D to float, causing the balls C, G, and so on to fly out. . Therefore, in some cases, a stopper may be separately installed, but this increases the cost.

The present invention seeks to eliminate such conventional drawbacks.

The embodiment shown in FIGS. 3 to 6 will be described below.

FIGS. 3 to 5 are examples of this, and in the conventional leaf spring E described above, the vicinity of the mounting base H,
That is, tongue-shaped stoppers 1, 1 are integrally provided at a location with high rigidity and little deflection, and are bent and protruded from the side edges toward the upper surface of the head chassis D. The length is set so that it faces the top surface with a slight gap.

Therefore, if this is used in the same manner as before, even if the leaf spring is bent due to an excessive shock due to a fall, etc., the amount of bending is extremely small at the stoppers 1, 1, and the rigidity is high, so the stopper 1 ，
1 sufficiently prevents the head chassis D from floating. In addition, the reason why the leaf spring bends when a shock is applied is mainly due to the force from the heavy head chassis D, and if the head chassis D is prevented from floating by the stoppers 1, 1, the plate springs will bend. Since the spring itself hardly bends, neither the lower ball C... nor the upper ball G... will fly out.

FIG. 6 shows another example of the leaf spring E. In this case, the stoppers 1, 1 are replaced with stoppers 2, 2 whose side edges face the upper surface of the head chassis D. It protrudes from one piece. This case is also substantially the same as the previous example.

Note that a stopper may be provided protruding from the mounting base H.

According to the present invention, since the leaf spring E integrally includes a stopper, the stopper can prevent the movable member from floating due to shock such as falling, and there is no need to install a separate stopper exclusively for preventing floating. There is no space problem for installation, the assembly is simple, and the cost is not high.
