The drive section described above together with the cassette housing 4 constitutes the cassette loading mechanism in this example. The main mechanisms of this drive unit, such as the rotating arm 20 and the guide groove 7, are rotated when the cassette housing 4 is at the stop position for receiving the tape cassette 3 inserted from the insertion opening 2. The side surface of the properly housed tape cassette 3 opposite to the operating side surface is located close to it, and in this example is located on the side plate 5a side of the internal chassis 5.

As shown in FIG. 3, the lever 40 is supported by a support shaft 41 attached to the upper plate 4c of the cassette housing 4, and is biased by a spring 42 in the direction of arrow b. The lever 40 has two arm parts 40.

When the switch 43 is turned on, the motor 26 is activated. shall be taken. The arm portion 40b pushes the tape cassette 3 toward the insertion opening 2 when the tape cassette 3 into which it has been inserted is taken out. In addition, the arm portion 40b
is provided with a boss 40b', and as shown in FIG.
The rotation of 5 is restricted.

As shown in FIG. 3, on the upper plate 4c of the cassette housing 4, a pair of cassettes are provided to press the front and back of the tape cassette 3 and keep it in the correct position when the tape cassette 3 is inserted with its lateral side facing forward and backward. Cassette holding pieces 44 and 45 are attached at positions corresponding to the rear end and the front end of the tape cassette 3, respectively, when the tape cassette 3 is fully inserted. Although the cassette pressing piece 44 is rotatably supported and biased in the direction of arrow c shown in FIG. 3, when the cassette housing 4 is in the state shown in FIG. 44
A boss 44a provided on the inner chassis 5 rides on a locking piece 46 fixed to the internal chassis 5, and is locked at the position shown in FIG. On the other hand, although the cassette holding piece 45 is rotatably supported and biased in the direction of the arrow d shown in FIG. 3, when the cassette housing 4 is placed in the state shown in FIG. It is engaged with the engagement piece that is not attached and is locked in the position shown in FIG.

Although not shown, the bottom plate 4a of the cassette housing 4 is formed with two circular through holes corresponding to the supply reel and take-up reel of the tape cassette 3. , are adapted to be attached to a supply reel stand and a take-up reel stand of a tape drive section (not shown) disposed below the bottom plate 4a of the cassette housing 4 through their respective circular through holes. A lid opening arm 47 is attached to the internal chassis 5 in order to open the front lid 3a of the tape cassette 3 when the tape cassette 3 is installed in the tape drive section in this manner. This lid opening arm 47 is held in a floating state for the purpose of preventing damage, etc., and is slightly biased in the direction of arrow e shown in FIG. A position regulating plate 48 is fixed to the bottom plate 4a of the cassette housing 4 in order to keep the lid opening arm 47 in the vertical position when opening the lid. A guide member 49 is provided in the internal chassis 5 to guide the tape cassette 3 when the tape cassette 3 is inserted into the cassette housing 4 by moving its lateral side surface back and forth.
is located near.

In an example of the recording/reproducing apparatus according to the present invention configured as described above, the tape cassette 3 moves back and forth along its lateral side surface through the insertion opening 2 to a stop position for receiving the tape cassette 3 inserted from the insertion opening 2. When the tape cassette 3 is inserted into the cassette housing 4, as shown in FIG.
The arm portion 40b of the lever 40 is pressed by the side wall of the lateral side surface portion which is the tip of the lever 40, thereby moving the lever 40 from the position shown by the dashed line to the position shown by the solid line against the spring force of the spring 42. In the process, the lever 35, whose rotation has been restricted by the lever 40, changes from the position shown by the dashed line to the position shown by the solid line, and as a result, the switch 32 is first turned on by the arm 35a of the lever 35. . When the lever 40 reaches the position shown by the solid line, the switch 43 is turned on by the arm 40a of the lever 40, it is detected that the tape cassette 3 is completely inserted into the cassette housing 4, and the motor 26 is turned on. becomes operational.

When the motor 26 is activated, its driving force is transmitted to the rotating arm 20 via the gear 27, thereby causing the rotating arm 20 to rotate to the left in FIG. 4. As a result, the pin 6 engaged with the elongated hole 24 of the rotating arm 20 is moved along the horizontally extending portion of the guide groove 7, whereby the cassette housing 4 is moved along with the entire moving block 10. It is moved to the left in Figure 3. At this time, the cassette holding piece 44 presses the boss 44 as shown in FIG.
When a is removed from the engagement piece 46, the rear end of the tape cassette 3 is held down. On the other hand, when the tape cassette 3 is completely inserted into the cassette housing 4, the cassette holding piece 45 is already in a state of holding down the tip of the tape cassette 3, and therefore the tape cassette 3 is held down as shown in FIG. As shown, these cassette holding pieces 44 and 4
5 and is positioned within the cassette housing 4. Note that the lever 35 has its engaging piece 35c' of the arm portion 35c in contact with the inner wall of the side plate 5a of the internal chassis 5 forming the through hole 36, so that its rotation is restricted. Further, the switch 43 is adapted to move along with the cassette housing 4.

The pin 6 that has been moved horizontally changes direction from the horizontally extending portion of the guide groove 7, and
It is moved along a vertically extending section. As a result, the cassette housing 4 is moved downward in FIG. 3 together with the sliding portion 16 of the moving block 10. Then, as shown by the dashed line in FIG. 6, the rotating arm 2
The arm portion 35b of the lever 35 is pressed by the protruding portion 23a of the first portion 23 of 0, thereby causing the lever 35 to rotate to the left in FIG. As a result, the switch 32 is turned off, the motor 26 is stopped, and the movement of the cassette housing 4 is thereby stopped, and the accommodated tape cassette 3 is mounted on the tape drive unit as shown in FIG. It will be in a state where it will take the stop position. In this state, the supply reel and take-up reel of the tape cassette 3 are connected to the supply reel stand and take-up reel stand of the tape drive section, respectively, through two circular through holes provided in the bottom plate 4a of the cassette housing 4. It will be installed. Then, the front lid 3a of the tape cassette 3 is lifted by the lid opening arm 47, which is set vertically by the position regulating plate 48, so that the magnetic tape contained therein can be loaded. In addition, in FIG. 6, the state in which the front cover 3a of the tape cassette 3 is opened is not shown.

Next, we will discuss the case where, for example, after playback, the tape cassette 3 is removed from the tape drive unit and returned to the insertion opening 2 side.In this case, although the switch 32 is in the off state, the motor is 26 is initially brought into operation regardless of the operating state of switch 32, and rotates worm 28 in the opposite direction to that in the above case, thereby causing rotation arm 20 to rotate to the right in FIG. It moves me. As a result, the pin 6 is moved within the guide groove 7 along a path opposite to that described above. The cassette housing 4 is therefore moved along a path opposite to that previously described, and the tape cassette 3 is removed from the tape drive. At this time, the lever 35 is disengaged from the rotating arm 20, and the switch 32 is maintained in the OFF state. Then, the pin 6 that has been moved in the vertical direction changes its direction from the vertically extending portion of the guide groove 7 and is moved along the horizontally extending portion. When the pin is in the horizontal direction, the lever 40 is rotated around the support shaft 41 at the fourth position.
It is rotated to the left in the figure. As a result, the lever 40 returns from the position shown by the solid line to the position shown by the dashed-dotted line, as shown in FIG. As a result, the tape cassette 3 is pushed out toward the insertion opening 2 by the arm 40b of the lever 40 pressing the side wall of the lateral side, and the switch 43 is turned off. Along with this, the lever 35 also moves to the fifth position.
As shown in the figure, the position shown by the solid line returns to the position shown by the chain line. As a result, the motor 26 is stopped, thereby stopping the movement of the cassette housing 4 and returning it to the state shown in FIG.

It goes without saying that the recording and reproducing device according to the present invention is not limited to having both a recording function and a reproducing function, and may have only a reproducing function or only a recording function.

Effects of the Invention As is clear from the above explanation, the recording/reproducing device according to the present invention has the insertion opening in a side portion of the front portion where the operation portion is provided, so that a plurality of recording and reproducing devices can be stored. In addition to disposing a playback device, there is also an accommodation mechanism section for accommodating a plurality of tape cassettes, and a tape cassette is taken out from this accommodation mechanism section, conveyed to a certain recording/playback device, and inserted into an insertion opening of the recording/playback device. When used in a system etc. that reproduces a video signal, one end of the transport mechanism is provided with a transport mechanism that is located on a side surface of the front surface where the operation section of the recording and reproducing device is provided. The transport mechanism can be placed at any location, and the transport mechanism does not interfere with the operation of the operating section of the recording/reproducing apparatus. In addition, since one end of the transport mechanism can be arranged in this way, the moving path of the tape cassette between the storage mechanism and the recording/playback device can be made straight, which simplifies and downsizes the entire system. change is being measured. Furthermore, according to the recording and reproducing apparatus according to the present invention, a tape cassette that is formed in a rectangular shape and has an opening for drawing out the tape on the vertical side surface is inserted with its horizontal side surface being forward and backward. Therefore, when used in a system such as the one described above, the tape cassette should be inserted into the storage mechanism with the tape drawer opening first, as is generally done. It is possible to transport and insert the disc into the recording/reproducing apparatus in that state.

In addition to the above, the recording/reproducing apparatus according to the present invention moves while accommodating the tape cassette inserted through the insertion opening, and moves to a stopping position for receiving the tape cassette inserted through the insertion opening. The main mechanism of the cassette housing selectively assumes a stop position for loading a tape cassette inserted into the tape drive, while the cassette housing is in a stop position for receiving a tape cassette inserted through the insertion opening. Since the side surface of a properly housed tape cassette opposite to the actuating side surface is driven by the drive section located close to the tape cassette, the tape cassette inserted into the device through the insertion opening can be moved relatively easily. It is efficiently attached to the tape drive unit through a short movement path.
