Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a cassette holder device used in a video tape recorder, and particularly to one that facilitates the attachment and detachment of a tape cassette.

[Technical background of the invention]

A conventional cassette holder device is constructed as shown in FIGS. 1 and 2. That is, a cassette holder 2 in which a loading port 3 for loading a tape cassette 1 is formed is connected to a pair of brackets 4 and 5 by four lift arms 6, 7, 8, and 9. . The lift arms 6, 7 on one side and the lift arms 8, 9 on the other side are pivotally connected at their intersections, respectively. One end of the lift arms 6, 8 is pivotally connected to the brackets 4, 5, and the other end engages with the sliding holes 10, 11 of the cassette holder 2. One end of each is pivotally connected to the cassette holder 2, and the other end engages with the sliding holes 12, 13 of the brackets 4, 5.
As shown in FIGS. 1 and 2, this cassette holder device is in the attachment/detachment state of the tape cassette 1 by raising the cassette holder 2, and is in the locked state by lowering the cassette holder 2 (a locking device (not shown) cassette holder 2 is locked).

[Technical background of the invention and its problems]

However, in recent years, as tape cassettes have become smaller and lighter, the structure has been designed to minimize the space between the top surface of the cassette holder 2 and the tape cassette 1, making it very difficult to operate when taking out the tape cassette 1 with your fingers. Moreover, the upper surface of the cassette holder 2 sometimes caused injury to the fingers.

[Purpose of invention]

The present invention has been devised in view of the above-mentioned conventional problems, and it is an object of the present invention to provide a cassette holder device that allows tape cassettes to be taken out safely and easily without compromising the size and weight of the device.

[Summary of the idea]

In the present invention, the above object is achieved by providing a holder cover above the loading opening of the cassette holder, and configuring the holder cover to open when the tape cassette is attached or removed from the cassette holder and close when the cassette holder is locked. are doing.

[Example of idea]

Embodiments of the present invention will be described in detail below with reference to FIGS. 3 to 5.

In FIG. 3, a cassette holder 21 for accommodating a tape cassette 20 is formed into a substantially channel shape, and a loading port 22 for loading the tape cassette 20 is provided at the front, and a loading port 22 is provided below the loading port 22. Guide ribs 23 and 24 are integrally formed. In addition, both sides 25 and 26 are located at the rear of the upper part.
A connecting portion 27 connecting the two is integrally formed. A holder cover 28 having side edges 29, 30 and a front edge 31 is disposed above the loading port 22. The rear ends of both side edges 29 and 30 of this holder cover 28 are pivotally connected to both side parts 25 and 26 of the cassette holder 21 by pins 32 and 33. Furthermore, sliding holes 34 and 35 extending in the front-rear direction are formed in both side edges 29 and 30, respectively.

The cassette holder 21 is connected to a pair of opposing brackets 36, 37 by four lift arms 38, 39, 40, 41. Lift arms 37 and 38 on one side are pivotally connected at their intersection by a pivot pin 42, and lift arms 39 and 40 on the other side are similarly pivotally connected at their intersection by a pivot pin 43. There is. and,
The lift arms 38 and 40 have one end attached to the side 2 of the cassette holder 21 with pivot pins 44 and 45.
5 and 26, respectively, and sliding pins 46 and 47 are provided at the other end, and these sliding pins 46 and 47 are connected to sliding holes 48 and 47 formed in each bracket 36 and 37, respectively. 49, respectively. The lift arms 39 and 41 are pivotally connected to the respective brackets 36 and 37 by pivot pins 50 and 51 at one end, and slide pins 52 and 37 at the other end, respectively.
53 and sliding pins 54, 55 are provided at a predetermined interval. The sliding pins 52 and 53 are engaged with sliding holes 56 and 57 formed on both sides 25 and 26 of the cassette holder 21, respectively. , 30, respectively.

Next, the operation of the cassette holder device having the above structure will be explained.

First, when the cassette holder 21 is lowered as shown in FIG. 47, 52,
53, 54, 55 are sliding holes 48, 49, 5, respectively
6, 57, 34, and 35 (to the right in each drawing) and become locked by a locking mechanism (not shown). In this locked state, the holder cover 28 is rotated clockwise by the action of the sliding pins 54 and 55 and closed.

Furthermore, when the lock is released and the cassette holder 21 is raised as shown in FIG. 5, the lift arms 38, 39, 4 are
0 and 41 rotate, and along with this, each sliding pin 4
6, 47, 52, 53, 54, and 55 slide toward the rear of the slide holes 48, 49, 56, 57, 34, and 35 (to the left in each drawing), so that the tape cassette 20 can be attached or detached. In this attachment/detachment state, the holder cover 28 is rotated counterclockwise by the action of the sliding pins 54 and 55 and opened. As a result, a sufficient space is created between the tape cassette 20 and the holder cover 28, making it easy to take out and load the tape cassette 20.

[Effect of idea]

In the present invention, as described above, a holder cover is provided above the loading opening of the cassette holder, and this holder cover is configured to open when the tape cassette is attached or removed, and close when it is locked. Therefore, the tape cassette can be removed and loaded safely and easily without compromising the size and weight of the device.
