Description

[Detailed description of the invention] This invention relates to a cassette mounting device in a cassette tape recorder, and more specifically,
This invention relates to an improvement in the wire that connects the cassette cover and the damper.

In a cassette tape recorder, generally,
Air or oil type dampers are used to soften the movement of the cassette cover when it is opened and closed when loading and unloading the cassette. A conventional example thereof is shown in FIG. That is, the cassette cover 1 is attached to a front opening of a cassette drive mechanism (not shown) including a magnetic head and a winding shaft so as to be openable and closable about a shaft fulcrum 2 at the lower end. The cylinder 4 is pivotally attached to a chassis (not shown), and the plunger 5 is provided with a through hole 6 for screwing. The cassette cover 1 and the damper 3 are operatively connected by a wire 7, but in this conventional example, ring portions 8, 8 are formed at both ends of the wire 7, and the ring portions 8, 8 are connected with screws 9, 9, respectively. It is screwed to the corresponding member by means of the screws. In this case, it is particularly necessary to insert a collar 10 in the screwed portion of the plunger 5 to reduce the tightening friction force caused by the screwed screwing. However, according to this method, if the screw 9 is tightened too strongly, the through hole 6 on the receiver side may become loose, so the tightening force must be moderated, and the collar 10 is not required. Therefore, the workability is poor and the cost is also unfavorable.

This idea was made in view of the above-mentioned drawbacks of the conventional technology, and its purpose was to provide a wire with a structure that could be easily locked to the plunger of the damper without using parts such as screws or collars. An object of the present invention is to provide a cassette mounting device.

Hereinafter, an embodiment of this invention will be described in detail with reference to FIGS. 2 and 3. In this example, the same reference numerals are given to the same parts as those shown in FIG. 1 described above.
Further, FIGS. 2 and 3 illustrate the essential parts of this invention, and please refer to FIG. 1 for the relevant parts.

In this invention, the plunger 5 is attached to one end of the wire 7 corresponding to the plunger 5 side of the damper 3.
A bent portion 11 is provided which is bent like a goose's neck and is inserted into a through hole 6 and locked therein. That is, this bent portion 11
has a first bent part 12 bent into a substantially U-shape at one end of the wire 7, and a first bent part 12 further bent along the axial direction of the plunger 5 from the end of the first bent part 12. and a second bent portion 13. In this case, the lateral width A of the first bent portion 12 is larger than the lateral width B of the locking end 14 of the plunger 5 associated with the through hole 6, and the bent base of the second bent portion 13 is The height dimension C from the end to the bottom of the first bent part 12 is the same as the above-mentioned locking end 1.
It is substantially larger than the plate thickness D of No. 4, thereby making the movement of the joint portion smooth. Further, the length of the second bent portion 13 is made larger than the diameter of the through hole 6. moreover,
Right side 12a on the base end side of the first bent portion 12
is preferably longer than the left side 12b on the second bent portion 13 side. By doing so, a more reliable state of engagement between the bent portion 11 and the through hole 6 can be obtained. The other end of the wire 7 is screwed to the cassette cover 1 as in the conventional example shown in FIG.

In the above configuration, in order to connect the wire 7 to the plunger 5 of the damper 3, a second
After inserting the bent portion 13 of 7 are reliably connected. To break this connection, just do the opposite of the above.

Therefore, according to this invention, the wire 7 can be attached without using parts such as screws and collars as in the past
and the plunger 5 of the damper 3 can be easily and reliably connected, which is extremely practical. The cassette cover may be made of a single plate that simply opens and closes the front opening of the cassette drive mechanism, or may have guide grooves at both ends for storing and holding the cassette. Of course.
