It passes through the through holes 3f and 5f in a closed state (see FIG. 8B) so as not to collide with.

As shown in FIG. 13, the first to eighth sensors 35, 36, 38, 39, 61-64 and the recording / reproducing machines 7, 8 are connected to a control circuit 73. The motor 24 of the drive mechanism 4 and the motor 53 of the lifting mechanism 43 are connected to the control circuit 73 via motor drivers 74 and 75,
The solenoids 48 to 50 of the clamp mechanism 42 are also connected to the control circuit 73 via solenoid drivers 76 to 78.

Further, the recording / reproducing machines 7 and 8 output the signal reproduced from the loaded tape cassette 9 to the monitor CRT 79 for display.

Reference numeral 80 denotes an operation unit, which is provided with operation keys such as a numeric keypad, and a desired tape cassette 9 can be designated from a plurality of tape cassettes 9 on the rotary base 3 by operating the keys. ..

Reference numeral 81 is a display section for displaying the number and recorded contents of each tape cassette 9. Therefore, the operator is
The tape cassette 9 is selected while observing the display of 1, and the tape cassette 9 to be monitored is designated by the operation unit 80.
Then, the motors 24 and 53 and the solenoids 48 to 50,
The recording / reproducing machines 7 and 8 are controlled by a command from the control circuit 73 as described later.

Now, the process executed by the control circuit 73 together with the operation of the recording medium ejecting apparatus 1 having the above-mentioned configuration will be described.

The control circuit 73 executes the processing of the flowchart shown in FIG. 14 before starting the reproduction. In the figure, step S
When 1 (the following steps are omitted) is designated by the operation unit 80 to reproduce the Nth tape cassette 9, S
2, the motor 24 of the drive mechanism 4 is rotationally driven. Therefore, the drive pulley 14 transmits the rotational driving force of the motor 24 to the rotation base 3, and the rotation base 3 rotates the rollers 13 ₁ to ₁ 1.
It is supported by 3 ₄ rotates while.

At the next step S3, the number of signals output from the first and second sensors 35 and 36 is counted along with the rotation of the rotary base 3, and the Nth tape cassette 9 _N is located at a position facing the recording / reproducing device 7. Check if you have moved to. In S3, when the pulse counter from the second sensor 36 becomes N, the process proceeds to S4, in which the motor 24 is stopped and the rotation base 3 is stopped.

In the next step S5, it is checked whether or not the third sensor 39 for detecting in-holder detects the tape cassette 9 _N in the holder 5 _N. If, when there is no tape cassette 9 _N is in the holder 5 _N returns to the previous S1, repeat the tape cassette specified operation. However, if the tape cassette 9 _N is stored in the holder 5 in S5, the process proceeds to S6,
The motor 53 of the lifting mechanism 43 is activated.

At the same time, the solenoids 48 and 50 are excited to hold the pressing rods 46 and 47 at their current positions.

When the motor 53 of the elevating mechanism 43 is activated, the rotational driving force of the motor 53 is transmitted to the feed screw 52 via the gears 60 and 59, so that the elevating base 44 is moved to the position shown in FIG.
1, rises from the standby position shown in FIG. Lifting base 4
4, the detected piece 44a reaches the detection position of the sixth sensor 62 and a detection signal is output from the sixth sensor 62 (S7), and the solenoid 49 is excited to raise the plunger 49a ( S8). As a result, the clamp arm 45 is rotationally displaced so that the pair of claws 67 and 68 are opened as shown in FIG.

Further, as the elevating base 44 rises, the pressing rods 46 and 47 enter the holder 5 and come into contact with the bottom of the tape cassette 9 _N.

The tape cassette 9 _N is located between a pair of V-shaped open claws 67 and 68, and is pushed up at the bottom thereof by the pair of pressing rods 46 and 47.

Then, as shown in FIGS. 15 and 16, the tape cassette 9 _N is separated from the holder 5 and inserted into a cassette insertion opening (not shown) of the recording / reproducing apparatus 7.

The recording / reproducing apparatus 7 has a built-in tape cassette loading mechanism (not shown) for automatically pulling the tape cassette 9 _N inserted into the cassette insertion port to the mounting position. Therefore, in the recording / reproducing device 7, the tape cassette 9 _N can be automatically reproduced only by inserting it into the cassette insertion slot.

When the seventh sensor 63 detects the detected piece 44a of the elevating base 44 in S9, it is confirmed that the tape cassette 9 has been inserted into the recording / reproducing device 7, and the process proceeds to S10 in which the elevating motor 53 is turned on. Inverting drive is performed to lower the elevating base 44. At the same time, the solenoid 49 is demagnetized to bring the pair of claws 67, 68 into a closed state as shown in FIG.

When the elevating base 44 is lowered to the standby position shown in FIGS. 11 and 12, the fifth sensor 61 is moved to the elevating base 4.
4 is detected (S11), and the lifting motor 53 is stopped. Then, the recording / reproducing device 7 is set in the reproducing mode, and the information (recording, sound) recorded in the mounted tape cassette 9 _N is displayed on the CRT 9 for monitoring.

In this embodiment, two recording / reproducing machines 7, 8 are used.
Therefore, the operation for loading the next designated tape cassette 9 into the other recording / reproducing apparatus 8 is executed in the same manner as above while the reproducing operation is being performed in one recording / reproducing apparatus 7. Therefore, the information is displayed on the monitor CRT 79 without a break.

This completes the loading operation of the tape cassette 9.

Next, the operation of taking out the tape cassette after the end of reproduction will be described.

After the reproduction is completed, the control circuit 73 executes the tape cassette take-out process shown in FIG.

In FIG. 17, the reproduction of the tape cassette 9 _N loaded in the recording / reproducing apparatus 7 is completed in S21, or the operation unit 80
When the reproduction ending operation is performed in step S22, the recording / reproducing device 7 checks whether or not the tape cassette 9 _N has been returned to the eject position.

That is, when the eject signal is output from the recording / reproducing device 7 in S22, the process proceeds to S23 and the lifting motor 5 is moved.
3 to start the elevating base 44 in the standby position (see FIGS. 11 and 1).
2 (see 2). At the same time, the solenoids 48 to 50 of the clamp mechanism 42 are demagnetized to remove the clamp arm 45,
The pressing rods 46 and 47 are lowered.

In the next S24, it is checked whether or not the elevating base 44 has risen to the position detected by the sixth sensor 62, and when the sixth sensor 62 outputs a detection signal, S
2, the solenoid 49 is excited. As a result, the plunger 49a of the clamp arm 45 moves upward to rotate the pair of claws 67, 68 in the opening direction as shown in FIG.

Further, the raising / lowering base 44 is raised so that FIG.
8, when the position detected by the seventh sensor 63 is reached as shown in FIG. 19 (S26), the lifting motor 53 is stopped (S27).

At the next step S28, it is confirmed that the fourth sensor 39 detects the tape cassette 9 _N ejected from the cassette insertion opening of the recording / reproducing device 7, and then the process proceeds to step S29 to demagnetize the solenoid 49. Therefore, the pair of claws 67, 68 provided at the tip of the clamp arm 45 rotate in the closing direction as shown in FIG. 9 to clamp the tape cassette 9 ejected from the cassette insertion port of the recording / reproducing device 7. At this time, hook 67c protruding end of the grip portion 67 of the pawl 67 is fitted into the recess 9a of the tape cassette 9 _N, the tape cassette 9 _N is locked by the pawl 67 and 68.

During this clamp operation, the pressing rod 4
Since the pair of claws 67 and 68 clamp the tape cassette 9 _N , the pressing rod 4 and
6,47 serves to regulate the inclination of the tape cassette 9 _N as the tape cassette 9 _N during operation of the pull is not in contact is not caught in the holder 5 _N.

Subsequently, in S30, the lifting motor 53 is driven in the reverse direction to lower the lifting base 44.

The tape cassette 9 _N ejected from the cassette insertion opening of the recording / reproducing machine 7 descends into the holder 5 while being clamped at the tip of the clamp arm 45 as the elevating base 44 descends.

In the next S31, it is checked whether or not the eighth sensor 64 has detected the lift base 44. When the lift base 44 is detected by the eighth sensor 64, the process proceeds to S32 to excite the solenoid 49. The plunger 49a is moved upward. Therefore, the pair of claws 6 of the clamp arm 45
7, 68 rotate in the opening direction to release the clamp of the tape cassette 9 _N as shown in FIG.

When the elevating base 44 is further lowered, the tape cassette 9 _N is housed and held in the holder 5.

When the detected piece 44b of the elevating base 44 has finished passing through the eighth sensor 64 in S33, the detection signal from the eighth sensor 64 is turned off, which causes S8.
Moving to 34, the solenoid 49 is demagnetized. Therefore, the pair of claws 67 and 68 rotate in the closing direction as shown in FIG.

Further, when the elevating base 44 descends, the claws 67 and 68 of the clamp arm 45 descend to the lower side of the rotating base 3, and the elevating base 44 moves to the fifth position in the next S35.
It is checked whether or not the vehicle has descended to the standby position detected by the sensor 61.

When the fifth sensor 61 detects the lift base 44 in S35, the process proceeds to S36 and the lift motor 53 is moved.
Is stopped and the elevating base 44 is stopped at the standby position.

In this manner, the recording / reproducing device 7 after the reproduction is completed.
The ejected tape cassette 9 _N can be taken out by the clamp arm 45 and returned to the holder 5.

Although the above embodiment has been described as an apparatus for taking out a video tape cassette, the present invention is not limited to this. For example, an apparatus for taking out a disk-shaped recording medium, that is, an optical disk, a magnetic disk, a magneto-optical disk, or the like. Of course, it can also be applied to.

Further, in the above embodiment, the holder 5 accommodating the tape cassette is radially installed on the ring-shaped rotary base 3, but the present invention is not limited to this, and the plurality of holders 5 are linearly arranged on the rectangular base. Of course, it may be arranged and the base may be linearly moved.

Further, it is not necessary to limit the number of recording / reproducing machines to two.
Alternatively, a plurality of units or two or more units may be provided.

In the above embodiment, two recording / reproducing devices 7,
Although 8 is provided upright in the vertical direction, it goes without saying that the recording / reproducing machines 7 and 8 may be installed in a horizontal state and the rotary base 3 may be rotated in a vertical state.

As described above, in the recording medium ejecting apparatus according to the present invention, the movable base supporting the plurality of holders is moved by the drive mechanism so that the predetermined holder faces the recording medium insertion opening of the recording / reproducing apparatus. The recording medium ejected from the recording / reproducing machine by the ejecting mechanism can be ejected from the recording medium insertion slot and returned to the opposing holder, which reduces the operation of the ejecting mechanism and simplifies the configuration and reduces the number of parts. The reduction makes it easier to manufacture and saves space. Further, since the moving base can be moved independently, the ejected recording medium holder can be searched in a short time, and the take-out / return operation time can be shortened.
