Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cassette insertion positioning mechanism of a recording / reproducing apparatus.

2. Description of the Related Art A conventional cassette insertion / positioning mechanism will be described below with reference to the drawings.

FIG. 2 is a perspective view showing the construction of a large cassette tape and a cassette holder showing an example of a conventional example, FIG. 3 (A) is a front view thereof, FIG. 2 (B) is a side view thereof, and FIG. FIG. 4B is a front view when a small cassette tape is inserted, and FIG.

In the figure, 1 is a large cassette tape, 2 is a cassette tape, and a VTR (not shown) is a recording / reproducing device.
It is a cassette holder to be mounted on. The cassette holder 2 is provided with stopper portions 4, 5, and 6 for determining the insertion position of the cassette tape 1, and the stopper portions
Reference numerals 4 and 5 are formed by cutting and raising a part of the holder 2, and a stopper 6 is formed by pinning the holder.

Further, the cassette 1 is provided with a lid 3 for protecting a stretched tape (not shown).
Notches 7, 8, and 9 are formed at positions where the notches 7, 8 and 9 are engaged.

In FIG. 3, reference numerals 16 and 17 denote side plates, which are fixed to a VTR chassis (not shown) on both sides of the cassette holder 1. Reference numerals 10 and 11 denote link arms for moving the cassette holder 1 substantially in the vertical direction with respect to the VTR chassis. The link arms 10 and 11 relate to the groove 13 provided in the cassette holder 1 and the groove 12 provided in the side plate 17 and their ends. Together, they form a link mechanism.

Although not shown, the left side (Side plate 16 side)
A link mechanism is also configured to hold the cassette holder 1. Reference numeral 14 denotes a connecting rod for connecting the left and right link mechanisms in phase.

When the cassette 1 is inserted into the cassette holder 2 in the direction of arrow A in this configuration, the cassette 1 cannot be inserted further back by the stoppers 4, 5, 6 and is set at a correct position. Also in the case of the small cassette 15 in FIG. 4, it is stopped by the stoppers 5, 6 as in FIG. When the cassette holder is pressed downward (arrow c), for example, manually from the state where the cassette is inserted at the regular position, the link mechanism is activated and the cassette is mounted on the VTR.

However, in such a configuration, in order to open and close the cassette lid 3 (arrow A), the cassette lid 3 must be provided with notches 7, 8 and 9 so as to avoid the stoppers 4, 5 and 6. Must. That is, a stopper for stopping the large cassette 1.
Notch 7,9 as escape for 4,6, 2 places, small cassette 15
The notch 8 as an escape of the stopper 5 for stopping the stop must be cut out at one place, that is, a total of three places. This restricts the position and size so that the stoppers 4, 5, and 6 do not hit the tape when the cassette is pulled down and the tape is pulled out. It is necessary to lower the height so that it does not hit the lower end of the tape.
And 6 become weaker and may bend. Further, since the cassette lid 3 has the cutouts 7, 8 and 9, dust or the like enters, leading to tape dropout.

Means for Solving the Problems The present invention provides an insertion position regulating stopper separately from the holder.

Operation The present invention eliminates cut-and-raise of the holder, eliminates notch of the lid, and reliably performs positioning by the above configuration.

Embodiment Hereinafter, a cassette insertion positioning mechanism according to one embodiment of the present invention will be described with reference to the drawings.

In the perspective view of FIG. 1, 18 is a large cassette tape, 19
Is a cassette holder for inserting the cassette tape and mounting it on a VTR (not shown). Reference numerals 21 and 22 denote side plates which are fixed to the VTR chassis (not shown) on both sides of the cassette holder 19. Reference numeral 23 denotes a stopper, which is fixed to the upper ends of the side plates 21 and 22. 24 is cassette tape 18
And a stopper for restricting the insertion position thereof in contact with the lid portion 20. In the present embodiment, the stopper is provided at three positions.
Although a link mechanism for moving the cassette holder substantially parallel to the direction of the VTR chassis is configured, it is equivalent to the conventional example and is not shown.

In this configuration, when the cassette 18 is inserted into the cassette holder 19 from the direction of arrow A, it is stopped by the stopper 24,
Stop at the regular position. This stopper 24 is a cassette lid
Since it stops at the front of 20, for example, it is made of a resin material that does not damage it. The position of the stopper 24 is determined by maintaining the position of the cassette from the start of cassette down in the direction of arrow C to the completion of the down after the cassette 18 is stopped by the stopper 24. That is, the stopper is used until the cassette 18 is fitted with the lower reel base (not shown).
24 must ensure that the cassette 18 does not move further back. Therefore, at the time of insertion, the cassette 18 is stopped at a position close to the bottom surface of the cassette 18, and the cassette 18 is positioned down on the reel base when the lid 20 descends along the stopper 24 even when the cassette 18 is down, and comes off the stopper 24.

Effects of the Invention As described above, according to the present invention, a cassette with no notch in the lid can be used, and dust does not enter. The tape is not restricted by the cut-and-raised portion of the holder as in the related art when the tape is pulled out, and the degree of freedom of the configuration is increased.
In addition, the strength of the stopper is configured stronger than before,
This leads to improved reliability.
