bottomed out. Also, the bent portion 14 of the clutch slider 14
d is at the position shown in FIG. 4, 14d' before the cassette is inserted, and during loading operation, it moves in the direction of the dashed arrow, and when loading is completed, it is located at the front end of the cassette 2 shown in FIG. 4, 14d. do. Furthermore, during the cassette ejection operation, the cassette 2 is moved in the direction of the solid arrow to push the front end of the cassette 2 and eject it out of the cassette holder 11.

(Cassette loading operation) The operation of the apparatus shown in FIGS. 1 to 4 will now be explained.

Figure 2 shows a state in which the cassette 2 is not inserted, and here the arm portion 1711 of the lever 12 is in contact with the side plate 12R (formed stop/412b), and the clock of the lever 17 is pushed against the tension hook of the spring 18. In addition, the clutch slider 14 is located at the lowest position to prevent rotation in both directions.Furthermore, there is a recess at the position of the bent portion 20m provided on the clutch slider 20, and its height is The height of the bent portion 20a is also low, and the height of H) in FIG. 1 is also low.

In this state, when the cassette 2 is inserted into the slot 11a of the cassette holder 11 and pushed to a predetermined position, the cassette detection switch CIN (Fig. 944) is closed, and the drive motor 6 rotates counterclockwise in Fig. 2. , the drive gear 25, and the drive pinion 24m via the communication gear 24b.
rotates clockwise. Since the upper rack portion 14L is in a position where it engages with the drive pinion 24a, the rotation of the pinion causes the clutch slider 14 and the slider 13 to slide to the right in FIG. As will be described later, the clutch slider 14 is urged upward by the spring 18 and the lever 17, and the guide pin 27 continues to slide along the lower end of the eject slider 2o. The bottle 11b is guided by the other side of the cam groove 13a, and is guided through the long holes 12m provided in the side plates 12B and 12L.
This causes the cassette 2 to move in the loading direction relative to the rotary drive unit.

When the slider 13 moves to the right and reaches a position where the guide pin 27 and the eject slider 20 are released,
The lever 17 rotates clockwise until it comes into contact with the tensile coil spring 18 and the strami 4 bin 31 installed in the slider 13, and as a result, the flexible arms 17L and 17U of the lever 17 are folded. Since the bent portion 14c is held between the clutch slider 14 and the drive pinion 24a, the clutch slider 14 moves upward and the drive pinion 24a moves the rack portions 14L and 14 of the clutch slider 14.
It reaches a disengagement position in which it does not engage with any of U and stops at this position.

Further, due to the upward movement of the clutch slider 14, the rowing completion switch LE provided on the slider 13 is closed, and the motor 6 is also stopped. The third mark indicates this loading completion state, and the retaining pin llb of the cassette holder 11
is the bottom of the cam groove 13a (cassette unloading operation) In Figure 3, when the eject button 28 is pressed, the eject slider 20 moves to the right and the eject slider detection switch EJ opens. Due to the operation of switch EJ, the drive motor 6 rotates again in the same direction as during loading, that is, counterclockwise in FIG.
similarly rotates clockwise. Further, as the eject slider 20 moves to the right, the guide pin 27 engages with the inclined portion 2θb of the slider 20, so that the clutch slider 14 moves further upward from the position shown in FIG. In this case, it is assumed that the flexible arm portion 17L of the lever 17 is set to deform within its elastic limit.

As the clutch slider 14 moves upward, the drive pinion 24tL engages with the lower thick portion 14U, so the slider 13 is moved to h1 when the drive pinion 24a is
In response to the rotation in the ゛ direction, # moves to the left in Fig. 3. As a result, the cassette holder 11 rises through a process reverse to the above-described loading operation. When the slider 13 moves to the left, just before the I-id pin 27 comes to the position of the folding force bending part 20a of the eject slider 2o, the arm part 17m of the lever noah comes into contact with the stone '+12b, and the spring 18
The lever 17 is rotated in the counterclockwise direction against the tensile force of the lever 17, and the clutch slider 14 is forced downward by the action of the flexible arm 14L of the lever 12. .

After that, when the guide bin 27 comes to the position of the bending part 20m of the Innoef slider 2o, the guide bin 27 is bent by the above-mentioned urging force and passes through the bending part 20m, and the clutch slider 14 is pushed by the above-mentioned urging force. Moving downward, the drive pinion 24g again engages with the upper thick portion 14L. On the other hand, downward leH of the clutch slider 14! At step b, switch LE is opened, motor 6 is stopped, and the initial state shown in FIG. 2 is returned.

(Cassette Ejection Operation) Next, the ejection operation of the cassette 2 in the above-mentioned unloading operation will be explained. The fourth leak explains this operation, and the bent part 14d of the clutch slider 14 in the figure is inserted into the first opening part 11c of the cassette holder 11 through the opening 12c of the side plate 12R as described above. When the iμ of cassette 2 is in its adult state, it is at the 1st position & 14 d' in the middle part of Fig. 4, but during the loading operation it moves in the direction of the broken line arrow in the same figure, and when the loading light is completed, the actual g14a It is located at the front end of the cassette as indicated by .

During the unloading operation, the folding portion 14d moves in the direction of the solid arrow in the figure to push the front end of the cassette/cassette 2 and eject it from the holder 11. That is, the folding portion 14d, which is integrally provided with the teleoper 14, moves under the cassette 2 in the loading direction during the loading operation, and moves in the ejection direction at the same height as the cassette 2 during the unloading operation.

According to the above-mentioned device, the clutch slider 14 moves in the vertical direction depending on the loading and unloading of the cassette 2, and the drive pinion 24a engages with the upper rack portion 17L and the lower rack portion 17U, respectively. Since the drive motor 6 rotates in the same direction, the loading and unloading operations of the cassette 2 can be performed by the drive motor 6, which rotates in the same direction.
The I motor and the drive piece fii control circuit described later are 1M7 simple 4
It is a mistake to make it 4'tJ Ebisu. Furthermore, the folded lrf&iW4.3 of the clutch slider 14 moves the lower side of the cassette 2 in the loading direction during the loading operation, and moves in the ejection direction at the same height as the cassette 2 during the unropping ink operation, and moves the front end of the cassette 2. is pressed to eject it from the cassette holder 11, so the unloading operation of the cassette 2 and the ejection excitation accompanying the cassette 2 (with a simple mechanism)
It can be done reliably. In the above embodiment, the bent portion 14d is integrated with the clutch slider 14, but the self-recording carrier storage container pressing means in this QIJ may be of any type as long as it is effectively interlocked with the clutch means. Further, its structure is not limited to a claw-like structure such as the bent portion 14.

(Head movement applied to this 5A light) (Figure 5,
Part 6) Up to now, the explanation has been made assuming that the drive motor 6 is dedicated to the loading and unloading operations of the cassette 2, but in embodying this invention, the head assembly motor is used for the aforementioned loading, etc. It can also be used for 11mm. A specific example will be described below. FIG. 5 shows a plan view of the head movement in that case, and FIG. 6 shows a sectional view taken along the line B--B in FIG. 5. Note that the above-mentioned FIG. 1 shows the state seen from above in the direction of arrow C in FIG. 5.

5 and 6, 1 and 2 are respectively a magnetic sheet or a magnetic disk which is the aforementioned record carrier and a cassette which is a record carrier storage container;
A motor, a so-called sheet motor or disk motor, is provided on the record carrier 1 with a center hub 1a.
A hole is provided in which the spindle 3a'AA of the motor 3 is inserted. In addition, the cassette 2) (without a box-shaped t, described later) has a recording or reproducing head 1, for example, inserts a magnetic head 4 and connects it to the record carrier 1. Center hub J 11) E low 4
% is provided. Spindle 3a
is integrally attached to the output shaft of the motor 3, and by being inserted into the center hub 1a during loading, the record carrier 1 is rotated by the motor 3 at a predetermined number of rotations.

5 is a head gear rear from which the recording or reproducing head is removed; 5a is an engaging portion thereof; 6 is a motor for moving the head 1, which is an example of a driving example for the head movement 1/3', rotary and the above-mentioned loading mechanism, etc. (For example, step motor], 7
is connected to the shaft of the lead screw 8, which is connected to the shaft of the motor 6 so as to rotate in the same direction as the shaft of the motor 6. The lead screw 8 is an X-point head screw for driving the head, and the retaining portion 5a of the head carrier 5 engages with it.

Reference numeral 9 denotes an I-id shaft of the head carrier 5, which is inserted into the hollow circle fH15 of the carrier 5, and 9' denotes another I-id shaft, which is an arm portion extending to the side of the carrier 5 (the head carrier portion is located below the needle). The above (1°4
From configuration C, depending on the forward and reverse rotation of the head drive motor 6, ＼
The rad carrier 5 moves in the vertical direction in FIG. 5, sequentially contacts the recording tracks, and performs recording or p) main operation.

IO is a tensile coil spring, and one end is fixed to the main body (not shown) and the other end is fixed to the head carrier 5, and the head carrier 5 is urged toward the center of the record carrier 1, and the head carrier 5 and the other end are fixed to the head carrier 5. The effect of backlash removal at the engagement portion 5a with the screw 8 is cured.

Next, the head access operation of the above head moving machine tH combined with the loading mechanism shown in FIGS. 1 to 4 will be described. During the aforementioned cassette loading operation, the head drive motor 6 continues to rotate in the counterclockwise direction δF in FIG. During this time, the head carrier 5 moves toward the outer periphery of the record carrier 1, and the head 4 and the engaging portion 5a move to the positions indicated by 4' and 5a' in FIG. 5, respectively. Here, the retaining portion 5tfi is located at the end of the lead screw 8, and while the S movement of the head carrier 5 further toward the outer periphery is stopped, the head drive motor 6 continues to rotate, and the loading operation proceeds. In this case, since the head 4 is located outside the recording track area on the outer circumferential side of the record carrier 1, there is no problem in driving the head during recording or reproduction.

To explain this relationship in detail, the amount of rotation of the motor 6 required from the start to the end of loading and from the start to the end of unloading is such that the head 4 can be moved to the innermost track of the record carrier 1 ( For example, a lot of rotational noise is made when moving from the 50th track to a predetermined position beyond the outermost track (first track). Even after the head 4 reaches the above-mentioned j5r fixed position, the engaging portion 5a of the head carrier 5 is disengaged from the screw 8 due to the excessive rotation of the motor 6, and the spring 100
The head 4 is held in this position as it remains in abutment with the end face of the leadscrew 8 (by action). Furthermore, head 4
It is also possible to deteriorate the recording medium so that it is located outside the recording track area on the inner circumferential side of the record carrier 1.

After that, if the motor 6 is rotated in the normal direction (rotation in the direction of moving the head 4 toward the center of the carrier 1), the engaging portion 5
Under the action of the spring 1o, the head engages again with the screw 8 and the head can be moved.When recording or reproducing,
As is well known, the force of the lead screw 8 (referred to as rotation Il) is increased depending on the forward and reverse rotation of the motor 6 for driving the head 9, and the force of the lead screw 8 is increased by the engagement of the retaining portion 5a and the lead screw 8. moves back and forth in the radial direction of the record carrier 1. In this case, the drive pinion 24a is not engaged with either the upper or lower rack portions 14L, 14U of the clutch slider 14 at the end of loading, so the above head access operation is performed. As described above, the drive pinion 24 & clutch slider 1
4, the head moving mechanism is driven by the head drive motor 6, but the drive pinion 24& engages with one of the upper and lower thick parts 14L and 14U. At this time, the output of the motor 6 is selectively switched off, and the loading or unloading mechanism of the cassette 2 is driven. Note that after loading is completed, the delay between the drive pinion 24a and the loading mechanism is cut off, so when recording or reproducing, the 1.
It does not affect the X11 degrees of the IK.

(Drive Motor Control Circuit) (Fig. 7) Next, the rotation and stop control circuit of the drive motor 6, which is necessary for the above-mentioned operation, will be explained with reference to Fig. 7.

In the figure, CIN, LE, and EJ are open-type cassette detection switches, loading completion switches, and ejector detection switches, which are connected to the power supply +Vc.
The resistors R1 and R2 and R3 are connected in series between C and the ground potential point. 51 is an AND circuit, one input of which is connected to the signal at the connection point a between the switch CIN and the resistor R1, and the other input is connected to the signal from the connection point a between the switch LE and the resistor R2 via an inverter 52. be done. 53 is a falling synchronized type R37 lip-flop, and its setting requires manual power S.
The eccentric force at the connection point C between the switch EJ and the resistor R3 is connected to the inverter 54, and the signal at the point a is connected to the reset force R, and the output of the inverter 54 changes from the high level to the low level. is set by a change in , and reset by a change in (M) at point a from a high level to a low level.

55V is an OR circuit to which the output of the AND circuit 5 and the output of the RS flip-flop 53 are input, and 57 is a motor/drive circuit to which the output of the OR circuit y, 5s is input. Note that the terminals 56 and 58 will be described later.

To explain the operation of the 7N circuit, when the cassette 2 (Fig. 4) is inserted into the cassette holder 11, the switch CI
Since switch N is closed and point a is at high level, switch LE is open and point b is at low level, so the output of inverter 52 is high level and the output of OR circuit 5'5 is also high level. Otherwise, the motor drive circuit 57 rotates the motor 6. As a result, the drive gear 25 (FIG. 2) rotates counterclockwise, so the drive pinion 24m rotates clockwise, and the shuck set 2 is rotated by the above-described operation.

When loading is completed, the eject slider 14 rises and the switch LE closes, so the potential at point b goes high, and the output of the AND circuit 51 goes low, so the output of the OR circuit 55 goes low). Drive circuit 57 stops motor 6. Note that in this case, the Q output of the flip-flop 53 is at a low level.

When unloading the cassette 2, the eject button 28 is set to 17 inches by the switch EJ or Hj, which causes the potential at the Jjc point to change from the low level to the city level.
Since the output of the inverter 54 changes from a high level to a low level, the flip-flop 53 is set, and since its Q output becomes a high level, the output of the OR circuit 55 becomes a high level. causes the motor 6 to rotate again. Since the slider 13 is engaged with the rack portion 14UiE drive pinion 24m of the two-way slider 14 as described above, it now slides to the left, and the unloading and ejecting operations of the cassette 2 are performed as described above. .

Note that even if the switch EJ is turned off, the S flip-flop 53 is held in the set state until the switch CIN is turned off, so even if the eject button 28 is released, the above operation will not continue as specified. The eject button 28 must be pressed until the guide bin 22 is raised onto the eject slider 20 in FIG.

Cassette 2 is ejected from port 11, and switch CI
When N is turned off, the potential at point a changes from a still level to a low level, so the flip-flop 53 is reset, the output of the OR circuit kiδ55 becomes a low level, and the motor drive circuit 57 stops the motor 6.

The above is a case where the motor 6 is a dedicated motor for loading operation, etc., but as shown in FIGS. 5 and 6, the head drive motor is
In the case where it is also used for motion, normal rotation and reverse rotation command signals are manually applied to move the No. 4 pad 4 forward and backward. When a stop rotation command signal is applied to the terminal 58, the motor drive circuit 52 rotates the motor 6 in the normal direction and moves it via the lead screw 8 and the engaging portion 5a, and when a reverse rotation command signal is applied to the terminal 56, the motor 6 rotates in the normal direction. It is applied via a circuit 55 to a motor flange movement circuit 57 which reverses the motor 6 and moves the head 4 from the center of the record carrier 1 towards the outer periphery. motor 6 here
The forward rotation of the motor 6 refers to the direction of rotation of the motor 6 that moves the recording or raw head 4 from the outer periphery of the record carrier 1 toward the center, and the reverse rotation of the motor 6 refers to the direction of rotation of the motor 6 that moves the recording or raw head 4 from the outer periphery of the record carrier 1 toward the center. Refers to the direction of rotation in which the object is moved toward the outer periphery. Furthermore, 61
The directions of rotation during loading and unloading described above correspond to the above-mentioned reverse directions.

Although the example in which the record carrier is a disc-shaped sheet or disk has been described above, the same applies to a device that loads, unloads, and discharges a storage container that stores this FyJI'i tape-shaped record carrier. (Moving bed) As explained in detail above, according to the present invention, loading and unloading of the record carrier storage container are performed by rotation of the J source in the same direction, and this clutch means has an effective Since a suppressing means is provided to eject the record carrier storage container in conjunction with n1, the structure of the drive source and the seven control circuit is
] In addition, the loading, unloading, and ejecting operations of the record carrier storage unit can be realized by a simple straw structure.
