Description

Description: BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a cassette mounting apparatus having a cassette holder reciprocally movable between a cassette insertion position and a recording / reproducing position. The present invention relates to a cassette mounting device that has a simple configuration and makes it easy to take out a cassette. 2. Description of the Related Art In a cassette mounting apparatus having a cassette holder which is reciprocally movable between a cassette insertion position and a recording / reproducing position, a part of the cassette is removed by grasping the cassette from the cassette holder. It is necessary to protrude from the cassette holder. In recent years, a cassette mounting device for selectively inserting a small cassette and a large cassette has been put to practical use. In this type of cassette mounting apparatus, generally, when ejecting a small cassette, the cassette cannot be protruded from the cassette holder to such an extent that the cassette can be grasped. For this reason, it is necessary to provide the cassette holder with a cassette discharging mechanism for discharging the small cassette. A conventional cassette discharging mechanism is disclosed in
As described in JP 12964, a rubber roller is pressed against a cassette to rotate the cassette, and the cassette is ejected. As described in JP-A-10-302355, a dedicated arm is rotated by using a cam mechanism, There are things that kick out cassettes. [0004] In the above-described conventional cassette discharge mechanism, the number of parts is large, a large occupied area is required, and the design of other mechanisms in the cassette mounting apparatus is greatly restricted. As a result, there has been a problem that the size and thickness of the cassette mounting device are greatly hindered. SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems. A cassette capable of discharging the cassette so that it can be easily grasped, having a small number of parts, occupying a small area, and having a small size and a small thickness. It is an object to provide a mounting device. In order to solve the above-mentioned problems of the prior art, the present invention holds a cassette (1) and reciprocates between a cassette insertion position and a recording / reproducing position. And a cassette lid opening / closing member (4) for opening / closing a front lid of the cassette, and after moving from the recording / reproducing position to the cassette insertion position, the cassette mounting device. Another object of the present invention is to provide a cassette mounting device, wherein at least a part of the cassette held by a holder is configured to protrude out of the cassette holder by the cassette lid opening / closing member. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A cassette mounting device according to the present invention will be described below with reference to the accompanying drawings. 1 to 3 are side views showing one embodiment of the cassette mounting device of the present invention, and FIGS. 4 and 5 are plan views showing one embodiment of the cassette mounting device of the present invention. As shown in FIGS. 1 to 5, a cassette mounting apparatus equipped with a cassette discharging mechanism according to the present invention comprises a cassette 1
Is provided. FIG. 1 shows a state where a cassette holder 2 holding a cassette 1 is located at a recording / reproducing position. FIG. 2 shows a state in which the cassette holder 2 holding the cassette 1 moves from the recording / reproducing position to the cassette insertion position in accordance with the discharging operation of the cassette 1 and the cassette holder 2 stops. FIG. 3 shows the state of the cassette 1 from the state of FIG.
Has been ejected from the cassette holder 2. FIG. 4 is a view of the state of FIG. 2 as viewed from above, and FIG. 5 is a view of the state of FIG. 3 as viewed from above. The present embodiment shows an example in which the cassette discharge mechanism of the present invention is mounted on a cassette mounting device for selectively inserting a small cassette and a large cassette. In FIGS. 1 to 5, the cassette 1 is a small cassette. The cassette discharging mechanism of the present invention is not limited to a cassette mounting device that selectively inserts a small cassette and a large cassette, but can be mounted on a cassette mounting device that inserts only one of a small cassette and a large cassette. As shown in FIGS. 1 to 5, on both sides of the cassette holder 2, sliders 3 which can move only in the horizontal direction (left and right directions in FIGS. 1 to 3 and vertical directions in FIGS. 4 and 5) are provided. Is provided. The slider 3 has a front cover 1 a of the cassette 1.
A cover lid opening / closing member (hereinafter, lid opener) 4 for opening and closing the cover is rotatably mounted. The slider 3 is also provided with guide pins 5a and 5b for reciprocating the cassette holder 2 between a recording / reproducing position and a cassette inserting position. The cassette holder 2 and the slider 3 are connected by a biasing member 6 such as a spring. 1 and 2
In the state of shifting to FIG. 2, the two are substantially integrated, and in the state of shifting from FIG. 2 to FIG. 3, the urging by the urging member 6 is released, and the two move independently. That is, although the cassette holder 2 comes into contact with a stopper (not shown) provided on the front surface of the apparatus shown by the dashed line and stops at the position shown by the dashed line, the slider 3 is further moved rightward. I have. In addition to the urging member 6, another mechanical lock may be used together. The movement of the lid opener 4 is controlled by regulating a guide pin 7 provided on the lid opener 4 by a cam groove 8. The lid opener 4 holds the front cover 1 of the cassette 1 at the recording / reproducing position shown in FIG.
It does not rotate except when opening a. Cassette holder 2
The slider 3 moves horizontally as the guide pins 5a and 5b move along the cam grooves 9 and 10, respectively. The cassette holder 2, the slider 3, and the lid opener 4 are driven by transmitting the driving force of a motor (not shown) to them by a plurality of gears (not shown). Cassette holder 2 holding cassette 1
However, when the cassette holder 2 reaches the state shown in FIGS. 1 and 2 from FIG. 1, the cassette holder 2 stops in the state shown in FIGS. In this state, the cassette holder 2 and the slider 3 are further moved as shown in FIG.
When the guide pins 5a and 5b move further rightward along the cam grooves 9 and 10 while being opposed to the urging force of the urging member 6,
The slider 3 moves rightward independently of the cassette holder 2. Then, the lid opener 4 pushes the cassette 1 to the right as shown in FIG. As a result, a part of the cassette 1 is discharged while projecting from the cassette holder 2 as shown in FIGS. As described above, the cassette mounting apparatus of the present invention
After moving from the recording / reproducing position to the cassette inserting position, at least a part of the cassette 1 held by the cassette holder 2 is projected by the lid opener 4, so that a dedicated member for projecting the cassette 1 is provided. There is no need to provide As described in detail above, the cassette mounting apparatus of the present invention includes the cassette lid opening / closing member for opening / closing the front lid of the cassette, and is provided after moving from the recording / reproduction position to the cassette insertion position. Since at least a part of the cassette held by the cassette holder is projected out of the cassette holder by the cassette lid opening / closing member, the cassette can be discharged so as to be easily grasped. Since there is no need to provide a dedicated member, the number of parts is small, the occupied area is small, and the size and thickness can be reduced.
