Description

[Detailed Description of the Invention] This invention relates to a half-loading device for a cassette deck, and more specifically, to a half-loading device that temporarily releases a half presser during half-loading.

Since the cassette deck uses a cassette half (hereinafter simply referred to as "half"), it is equipped with a half holder so that this half can be loaded in the correct loading position and maintained in that state. It is configured to operate in the direction of suppressing the Therefore, when the half is not loaded, the half retainer protrudes into the housing space for the half, and the half retainer obstructs the loading of the half. Therefore, when loading a half, the half holder is first released to prevent the half from interfering with the half holder.To release the half, the half holder must be manually pushed away during loading. The current situation is that

Therefore, while ejecting a half is automatically performed by an ejector, loading a half requires manually releasing the half presser, making the loading operation cumbersome.

So, this idea allows you to load the half without resistance.
This is to make it easier to do so.
When half-loading, the half-holding is temporarily released.
In other words, the ejection state allows the half to be loaded without resistance.

The details of this invention will be explained below with reference to the attached drawings. First, reference numeral 10 denotes a half holder commonly known as a kangaroo pocket, which is pivotally supported on the chassis.When this half holder 10 is loaded with a half H and is pushed into the storage section, the half holder 11 causes the back of the half to be pressed. It has a structure in which the edges are suppressed. One or two of these half retainers 11 are arranged along the width direction of the half H, and the middle part is supported by a pivot shaft 12 supported by a chassis, and a spring 13 gives it the habit of tilting in the half retainer direction. It is being The half side of the half presser 11 is a presser claw end 11a, and the other end is a lever end 1.
It is becoming 1b. A bell crank type release lever 2 constituting the transmission mechanism 20 is attached to the lever end 11b.
The first drive end 21a is arranged at the push-in position. The other end of this release lever 21 is a slide plate 22
The intermediate portion is pivotally supported by a pivot pin 21c to convert the linear reciprocating motion of the slide plate 22 into the rotational motion of the release lever 21. The slide plate 22 has a guide pin 22b in a long hole 22a corresponding to the stroke so that it can move linearly.
is inserted and supported.

Further, at the other end of the slide plate 22, one end of a bell crank type drive lever 23 is connected to a connecting end 23a.
The other end of the drive lever 23 is a holding end 23b, and the middle part is connected to the pivot pin 2.
The holding end 23b is located below the holding end 24a of the transmission lever 24 which is pivotally supported by the drive mechanism 30 and receives power for lever movement from the drive mechanism 30. The other end of the transmission lever 24 is a contact end 24b for the drive cam, and a pivot 25 is pivotally supported at the intermediate portion.

The transmission lever 24 has a contact end 24b.
The tension spring 32 is in contact with the circumferential surface of the drive cam 31.
The driving cam 31 is connected to a motor 33 that controls the mode of the cam, and a group of reduction gears 34.
It is rotated by The drive cam 31 is the protrusion 3
1a is in the drive position, and the half detection switch 40 detects the presence of the half H, the power to the motor 33 is turned on, and when the protruding portion 31a pushes up the contact end 24b of the transmission lever 24, the motor 33 is activated. One revolution to the first stop position, or
It is controlled to reverse, return, and stop.
The half detection switch 40 is in the "on" position before the half is completely loaded, and is pressed by the half.

Next, the operation of the half loading device for a cassette deck according to this invention will be explained. First, when the half H is loaded into the half holder 10 and the half holder 10 is pushed in, the half detection switch 40 is pushed by the half H and the power of the motor 33 is turned on. The motor 33 rotates the drive cam 31 through a reduction gear set 34, rotating the drive cam from the stop mode to the drive mode. Opposite to the contact end 24b of the transmission lever 24 pushed up by the protrusion 31a of the drive cam 31, the holding end 24a holds down one end of the drive lever 23 and is rotated. With this rotation, the other end is connected to the slide plate 22, so this slide plate 22 is connected to the guide pin 22.
b, in other words, it moves linearly and rotates the release lever 21. This release lever 21
The driving end 21a is the lever end 11 of the half presser 11.
b is held down, the holding claw end 11a is temporarily released against its habit, and the half H is allowed to be pushed in. When the half H is placed in the loading position together with the half holder 10, the holding claw end 11a is released. This suppresses H.

As is clear from the above explanation, the half loading device for a cassette deck of this invention is configured to detect the half when loading the half and use the power of the motor to temporarily release the half presser. smoothly without any resistance,
You can easily load a half.
