Description

[Detailed Description of the Invention] The present invention is a cassette tape recorder in which the cassette is inserted into the cassette loading container at the upper cassette insertion recording/playback standby position and then moved to the lower recording/playback position for loading. Regarding a loading device.

A cassette tape recorder comprising a cassette loading container that moves between an upper cassette insertion position and a lower recording/playback position, and by inserting a cassette into the cassette loading container, the cassette moves together with the container to the lower recording/playback position for loading. In the cassette loading container, as soon as the insertion of the cassette into the cassette loading container is completed, the cassette is rapidly moved downward with the cassette loading container to the recording/playback position. When inserting a cassette, the user presses his or her fingertip strongly against the end of the cassette, and as the cassette rapidly moves downward, the end of the cassette strongly rubs the fingertip in a direction perpendicular to the pressing direction. Therefore, there is a risk of injury to the fingertips, and especially if the cassette is inserted by pressing the toe instead of the fingertip surface, there is a high risk of chipping or peeling the toe. Causes a feeling of anxiety.

The present invention aims to solve the above-mentioned conventional problems in a cassette tape recorder that can be loaded by inserting a cassette. By temporarily blocking the cassette from moving downwards, and then allowing the cassette to move downwards to the recording and playback position together with the cassette loading container when the cassette returns a little, the cassette insertion operation is completed and the fingertips are removed from the cassette. To provide a cassette loading device capable of completely inserting a cassette by preventing the cassette from moving downward unless the cassette is released.

Further, the guide element 15 serves to guide the slide member 6 in the sliding direction.

Hanging plate 5 suspending cassette loading container 4
A locking body 16 is attached to the lower surface of the cassette so as to face downward and lock the cassette at the end position of the cassette. This locking body 16 is composed of a pin 18 having a flange 17 formed on the lower end side to lock onto a convex portion on the front end surface of the cassette in the insertion direction. In the drawing, the cassette is designated by the reference numeral 19, and its protrusion is designated by the reference numeral 20. In the cassette tape recorder of this embodiment, the cassette 19 is inserted in the longitudinal direction.
It is loaded as a so-called vertical insertion. The convex portion 20 of the cassette 19
They are formed on both end faces of the 9, and are provided in all existing products according to the standard.

6 and 7 are other embodiments, respectively. In both the structure shown in FIG. 6 and the structure shown in FIG.
The difference is that the former has its claw 21 engaged with a convex portion 20 of the cassette 19, and the latter has its claw 22 engaged with the lower edge of the cassette 19 on the front end surface side in the insertion direction.

In the cassette tape recorder of the first embodiment shown in FIGS. 1 to 5, when loading the cassette 19, insert the cassette 19 into the cassette loading container 4 at the cassette insertion position through its insertion opening 11, and press it with your fingertip. If loaded, cassette 19
The insertion front end surface of the cassette insertion sensing lever 7 contacts the cassette insertion sensing lever 7, and the cassette sensing lever 7 moves together with the slide member 6 against the spring 10 in the insertion direction of the cassette 19. Then, the cam portion 8 of the slide member 6
When the mounting point 14, which is the moving point of the tumbler spring 12, moves downward beyond the dead point passing through the guide 15, The cassette loading container 4 moves to the lower recording and playback position,
The cassette 19 is loaded into the recording/playback position. The mechanism for vertically moving the cassette loading container 4 of this embodiment from the upper recording/playback standby position to the lower recording/playback position was developed by the present applicant in 1983.
33478, the mechanism for vertically moving the cassette loading container 4 is not limited to this embodiment, and various other mechanisms can be used.

Next, FIG. 5 will be explained. Figure 5B,
When the insertion of the cassette 19 into the cassette loading container 4 of C is completed, that is, at the insertion end position of the cassette 19 in the upper recording/playback standby position, the front end surface of the cassette 19 in the insertion direction is aligned with the pin 1 of the locking body 16.
8 and the collar 17 is locked to the protrusion 20 on that surface, so that the cassette loading container 4 is temporarily prevented from moving downward. And the fifth
When the fingertip pushing the cassette 19 shown in Figure D is released from the cassette 19, the cassette 19 will release the spring 10.
The convex portion 2 of the cassette 19 is pushed back in the direction of the cassette insertion slot 11 by the biasing force of the cassette insertion detection lever 7, and the cassette 19 moves slightly in that direction due to the tilting of the hanging plate 5.
0 comes off from tsuba 17. Therefore, at that position, the cassette 19, together with the cassette loading container 4, is rapidly moved downward to the recording/playback position by the action of the tumbler spring 12, and is loaded (FIG. 5E).
As mentioned above, the cassette 19 is pushed back a little from the insertion end position and moved to the lower recording/playback position and loaded, so at this slightly returned position the cassette 19 is moved to the lower reel stands 2, 3, etc. The relative positions have been adjusted to match.

In the other embodiment shown in FIG. 6, when the cassette 19 is slightly returned from its insertion end position, the protrusion 2 of the cassette 19 is removed from the pawl 21 of the locking body 16.
0 comes off, and in the case of the other embodiment shown in FIG. Then, the cassette 19 is loaded into the recording/playback position.

In order to remove the cassette 19 loaded at the recording/playback position, the slide member 6 is slid toward the cassette insertion slot 11 by the spring 10 by manual or automatic eject mechanism operation, so that the tumbler spring 12 returns to the Det point. The attachment point 14 moves upward, the cassette loading container 4 returns to the upper cassette insertion position, and the cassette 19 is pushed out from the cassette insertion opening 11.

As is clear from the above description, the cassette loading device in the cassette tape recorder of the present invention has the following features:
The cassette loading container includes a cassette insertion detection lever that is elastically biased in the opposite direction to the cassette insertion direction and is pushed by the cassette inserted into the container, and a cassette insertion detection lever that locks onto the cassette at the end of cassette insertion and moves downward with the container. Since the cassette is equipped with a locking body that prevents the cassette from moving downward, even if the cassette is pushed with the tip of a finger and inserted to the final insertion position, the cassette will not move downward to the recording and playback position. When you take your finger off the cassette, you can move it to the lower recording and playback position. Therefore, according to the present invention, the fingertips will not be strongly rubbed by the end face of the inserted cassette, and there will be no risk of injury or anxiety. In particular, even if the cassette is inserted by pushing it with the tip of the toe instead of the surface of the fingertip, there is no risk of chipping or peeling off the nail, and the cassette can be inserted safely.
