With this structure, the switches BR1 to BR4 provided on the second sliding plate 3 slide in accordance with the sliding movement of the second sliding plate 31 in the direction of arrow A or B, and the sliding movement in the direction of arrow A is performed. In this case, the switch SWc is opened at the manual insertion completion position, and in the sliding movement in the direction of arrow B, the switch SWU is opened at the photon ejection position.

Note that the arrangement of these switches is such that the brushes BR1 to BR4 are placed on the ceiling surface of the cassette holder 7, and the brushes BR1 to BR4 are placed on the ceiling of the cassette holder 7, and
It is also possible to provide conductor turns P1 and P2 on the upper surface of the conductor.

Figure 9 shows gear unit 2 that supports the one-way clutch.
A perspective view of 4 is shown.

In the figure, 29 is a rack provided on the second slide plate 3, and 59 is a gear that meshes with the rack 29. A flange 60 has a notch 6 and is integrally formed with the gear 59. 62 is mounted on a coil spring.

A gear 64 enables the transmission of driving force, and meshes with the gear 23 as shown in FIG. 65 is a circle l&I ffVs formed integrally with the gear 64, 62 is a coil spring, and its bent portion 63 is a notch provided in the flange 60. As shown in the figure, a gear equipped with such a mechanism This is a gear shaft that pivotally supports the unit 24 on the chassis 5.

Next, the operation will be explained. When the cassette 2 is manually inserted, the rack 29 moves in the direction indicated by the arrow along with the second slide plate 3. Due to this, the p1 gear 59 rotates about the gear shaft 37 in a counterclockwise direction. At the same time, Franz 60, which is integrated with gear 59, is also rotated counterclockwise, and coil spring 62, which is engaged with notch 6 of Franz 60, is also rotated counterclockwise.

However, since this direction of rotation is the direction in which the inner diameter of the coil spring 62 widens, the gear 64 and the gear 64 integrated therewith (44
No rotational torque is transmitted to the formed cylindrical portion 65, and the gear 59, Franz 60, notch portion 6), and coil sill ring 62 rotate idly. Next, when a rotational torque is applied from the gear 23 meshing with the gear 64 and the gear 64 is rotated counterclockwise, the circular surface portion 65 integrally formed with the gear 64 also rotates counterclockwise. This is the coil spring -,, -t+t1A/+ze1l-P1. f-ichino・

The coil spring 62 and the cylindrical part 6
A friction force of 1φ is applied to the coil spring 62. Bending portion 63. Notch 'ffB 61 + Franz 60. A force of 1 is applied to the rack 29 via the gear 59 to move it in the direction of arrow A.

When the cassette 2 is ejected, the gear 64 is rotated clockwise by the rotational torque applied by the gear 23, and this direction of rotation is a direction in which the inner diameter of the coil spring 62 is widened. By the way, a one-way clutch has the characteristic of transmitting driving torque for rotation in one direction and not transmitting driving torque for rotation in the wrong direction, or it is applied to the gear on the idling side, so that the load is lower than the one-way clutch. Under the condition that the load applied to the gear to which the driving force is applied is increased by 1%, the driving torque can be transmitted even for rotation in the opposite direction. Therefore, due to the fact that there is a slight Mm force between the coil spring 62 and the cylindrical part 65, the weight of the cassette 2 applied to the rack 29, the j ridge line between the second slide plate 3 and the cassette holder 7, etc. Gears 23 and 22 and worm wheel 2 applied to the gear 64 side relative to the load
By setting the negative I dI by the gear train of the worm gear 20, the first partially toothed gear 25, and the second partially toothed gear 27, idle torque is generated in the one-way clutch, and the rack 29 is moved as shown by the arrow B. It depends on whether you move it in the direction.

(Cassette mounted JJX operation) Next, the cassette loading operation will be explained.

In FIG. 4(a), the cassette is manually inserted into the cassette holder 7 from the direction of arrow C, and the tip of the cassette 2 is held between the leaf spring 34 and the cassette holder 350. Then, when the cassette 2 is further pushed in the direction of the arrow A by hand, the second slide plate 3 moves along the long groove 33 that engages with the piston 32 set on the cassette holder 7 and the recessed groove. It is slid in the A direction. At this time, the rack 29 fixed to the second slide plate 3 also moves in the direction of arrow A, but the gear unit 2 that is meshing with the rack 29
Drive torque is not applied to gear 23 by the one-way clutch provided at gear 4. When the cassette 2 is held between the leaf spring 34 and the cassette receiver part 35 and is further pushed by hand in the direction of arrow A, the free end 34a of the leaf spring 34 is pushed down by the regulating part 36, as shown in FIG. The situation is as shown in . At the straight position 11J (first position), a cassette insertion detection switch (not shown) is activated. For this,
Electricity is supplied to the loading motor 19, and the loading motor 19 rotates in the clockwise direction. Therefore, the worm gear 20 is forced to rotate the worm wheel 2 and the gear 22 in a counterclockwise direction, the gear 23 in a clockwise direction, and the gear unit 24 in the counter+qJ, il direction. At this time, the rack 29 is given rotational torque from the gear 23 by the one-way clutch provided in the gear unit 24, and continues to move in the direction of the arrow. Second
The slide plate 3 is slid in the direction of the arrow along the long groove 33 which is engaged with the bottle 32 and the sliding plate. As the regulating portion 36 acts on this, the cassette clamping force between the plate spring 34 and the cassette receiver portion 35 is increased by a certain amount.

At the initial position, the first partially toothed gear 25 and the second partially toothed gear 27 are set to Mf, 1 by a spring and a positioning member (not shown).
The toothless portion of the toothless gear 25 and the gear 22, the second toothless gear 2
The missing teeth of gear 2 and gear 26 are located so as to face each other (see FIGS. 4(a) and 4(b)).
2 rotates, the l-th partially toothed gear 25 and the second partially toothed gear 2 rotate.
It does not rotate with 7.

As the rack 29 moves in the direction of arrow A, the lever 57
The lever also moves in the direction of arrow A, contacts the lever 28, and rotates it clockwise as shown in FIG. This results in
A first partially toothed gear 25 coaxially connected to the lever 28 and l-
142 partially toothed gears 27 both rotate in the direction of the hour clock. First, the first partially toothed gear 25 meshes with the gear 22 rotating counterclockwise, and the first partially partially toothed gear 25 is rotated clockwise. As a result, the second missing box gear 27 also moves towards the special training area.
- Rotate the ZER 26 in the anti-training direction, move the rack 1 in the direction of arrow A, and move the first slide plate JL) in the direction of the arrow. The rotational torque of the gear 26 is the rotational torque of the rotational shaft 3.

It is applied to the gear 26' meshing with the other M
4 Slide the l slide plate No. 0 in the direction of arrow A,
The direct-acting cam 49 is also moved in the direction of arrow A.

The pin 12 set 4111 times on the side surface of the cassette holder 7 and the pin 17 set 111 times on the side surface of the rad 44 are guided by Naganuma I and 16 and cam grooves 13 and 18, and move downward. The cassette holder 7 and the cassette holder 44 begin their downward movement.

The second slide plate 3 includes a pin 32 set on the cassette holder 7 and a long pin 33 provided on the second slide plate 31.
Since the cassette holder 7 is held in place by the cassette holder 7, it descends as soon as the cassette holder 7 starts moving downward, and at the same time, the rack 29 also starts descending. As the rack 29 descends, the gear unit 24 and the rack 29 disengage, and the second slide plate 31
slide in the direction of arrow A by 1? Stop. The first slide plate 10 transfers the rotational torque of the loading motor 19 to the worm gear 20. The arrow A
The cassette holder 7 and the knockout 44 continue to move in the direction, and when they reach the loading position (second position), they stop moving.

Next, refer to Figures 3 and 6 and check the center core suppression section).
'),' 4 G and band 440 action will be explained.

The rotational torque of loading motor J9 is worm gear 2
0. Worm wheel 2 and gear 22. First partially toothed gear 2
5 and the second partially toothed gear 27. The rotational torque of the gear 26 is applied to the gear 26' via the rotating shaft 30, and moves the rack J1' in the direction indicated by the arrow. As a result, the direct-acting cam 49 fixed to the side surface of the other first slide plate 10 also moves in the direction of arrow A.

After the cassette holder 7 has descended to the loading position, the direct-acting cam 4 is pressed against the pin 48 of the center core pressing member 46.
9-1 When the foot surface is positioned, the center core is pressed and the 4
6 rotates in the direction of the arrow around the rotation center axis 47,
From the position shown by the two-dot chain line to the position shown by the solid line, a pressing force is applied to the center core 3 by the tip 46' of the center core pressing member 46, and the center core 3 is press-fitted into the spindle 53 of the 7-tot rotating motor 54. As the first slide plate lO further moves in the direction of arrow A, the pin 48 is positioned on the low lift surface of the direct-acting cam 49, thereby causing the center core pressing means 46 to rotate in the direction of arrow E. It is covered at the position shown by the two-dot chain line.

When the cassette holder 7 is lowered, the pad 44 is moved by sliding the first slide plate JO in the direction of arrow A! The guide 7 is guided by the shaft 45 and descends from the position 11 shown by the two-dot chain line to the position shown by the solid line. In this way, the 7F head 44 closely faces the upper surface of the magnetic sheet, and the contact between the magnetic sheet 1 and the magnetic head 56 can be improved. Then, the switch for terminating the first slide plate 10 in the direction of the arrow is actuated, and the rope'ing motor 1
It stops after 90 rotations.

After that, the 7-tot rotation motor 54 is rotated (Niwaki/-
The magnetic head 56 rotates the magnetic seal l-1.
Record or keratinize.

In addition, during recording and reproduction, the magnetic head 56 is continuously or intermittently moved in the radial direction of the magnetic node 1-1 by a head moving table 56', as shown by arrows F and G in FIG. .

(Cassette ejection operation) Next, the cassette ejection operation will be explained.

When the not-shown ino-ext key is operated, the rotation of the notebook rotation motor 54 is stopped at one level, and the ino-ext switch (not shown in FIG. , for example, starts rotating counterclockwise. The counterclockwise rotation of the loading motor 19 causes the worm wheel 2 and gear 22 to rotate clockwise via the worm gear 20. gear 220
Clockwise r#1tHa Ii-+1 City 2 Irf I'l'+
&? 92 1-% 1 θ) Both the Od seat tr lower and the second partially toothed gear 27 rotate counterclockwise. Due to the counterclockwise rotation of the gear 23, the gear unit 2
4 rotates clockwise. The rotation of the second partially toothed gear 27 in the anti-training direction is transmitted to the gear 26, and the gear 26 is rotated in the time-open direction. Due to the clockwise rotation of the gear 26, the rank 1 starts moving in the direction of arrow B, and the first slide plate 1O also starts sliding in the direction of arrow B. As a result, as the rotary cam 49 moves in the direction of the arrow B, the center core pressing force 46 is located at the foot surface of the pin 48 or the linear motion cam 49 from the 1 degree lift surface.
The pin 48 is rotated in the direction of the arrow from the position shown by the dotted chain line to the position shown by the solid line, and then the pin 48 is positioned on the lower foot surface of the rotary cam 49 by continuing to move in the direction of the arrow B. and returns to the position shown by the two-dot chain line. The four pins 14 erected on the first plane of the cassette holder 7 and the pins 17 set up on the first plane of the guard 44 are connected to the long grooves 9 and 16 provided in the side plate 8 and the first slide plate lO. It starts to rise guided by the provided cam grooves 13 and 18, thereby causing the set holder 7 and pad 44 to rise.

In this way, as the first slide plate 10 slides in the direction of arrow B, the center core pressing portion 46 returns to the initial position, and then the cassette holder 7 rises and returns to the initial position, and the pad 44 When the gear returns to the initial position, the gear 26 rotating clockwise and the gear 31 rotating counterclockwise.
Is it the meshing of the second partially toothed gear 27 rotating in the direction?
It is released by the toothless part of the second toothless gear 27, and the gear 26
The transmission of the driving torque to the first sliding plate 10 is cut off, and therefore the first sliding plate 10 stops its sliding movement.

On the other hand, as the cassette holder 7 rises, the second slide plate 3 also rises, and the rack 29 is again connected to the gear unit 24 and 1.
l121f matches. Since the gear unit 24 is rotating clockwise when the cassette holder 7 is lowered,
Rack 29 is moved in the direction of arrow B. Since the gear unit 24 is equipped with a one-way clutch, the nitriding torque of the one-way clutch is used to move the rack 29 in the direction of arrow B. 2 slide plate 31
By taking into consideration the frictional load of the cassette holder 7, etc., the rotational torque can be transmitted to the rack 29 without causing any hindrance to the ejection operation of the cassette 2.

As described above, even after the meshing between the second partially toothed gear 27 and the gear 26 is released, the first false gear 25 is still meshed with the gear 22, so the gear 22 is rotated clockwise. The toothless gear 25 of the HRI, the second toothless gear 27, and the lever 28B are rotated counterclockwise, and the toothless portion of the toothless gear 25 of il is opposed to the gear 22, whereby the first toothless gear 27 and the lever 28B of the HRI are rotated counterclockwise. The meshing between the toothed gear 25 and the gear 22 is interrupted, and the transmission of the driving force to the partially toothed gear 25 is interrupted. The gear 27 and the lever 28 are returned to the initial positions shown in FIGS. 4(a) and 4(b) by means of a spring and a positioning member (not shown).

Now, since the loading motor 19 is still rotating, the rank 29 is further moved in the direction of arrow B by the gear unit 24, and the second slide plate 3 is also moved in the direction of arrow B.
The leaf spring 34 and the cassette holder 35 move from the position shown in FIG. 5 to the position shown in FIG. At the fully protruding position, a cassette ejection completion detection switch (not shown) is activated.This cuts off the introduction to the loading motor 19 and completes the ejection operation of the cassette 2.

(Effects) As explained above, according to the present invention, the first and second driving means for moving the record carrier storage container holding means in the container insertion direction and the container loading direction different from this are provided, and a second driving means; 11. A selective power transmission means is provided at the same time as the uU source, and when the record carrier storage container holding means is moved to a predetermined position in the container insertion direction by the first driving means, the power transmission means is activated. second
Since the drive means is actuated, it is possible to load the record carrier storage container by moving the record carrier storage container holding means in the container insertion direction and switching the moving direction to the container loading direction. Compared to a conventional loading device using a rotating lever, the device can be made smaller in size, and the entire recording or reproducing device can be made flatter and smaller.
