Abstract

PURPOSE:To load assuredly a cassette with soft operating force, by making use of the driving power of a motor to displace the cassette to a prescribed position when the cassette is loaded. CONSTITUTION:When a cassette 12 is loaded into a tray, the cassette 12 touches a stopper 25 and give a right displacement to slide levers 22 and 17 as well as a start lever 30. As a result, the lower side 23a of a bent part 23 of the lever 22 gets out of a driving roll 38. Thus a notched gear 36 can turn right. While the tip 30a of the lever 30 presses a pin 37 to turn the gear 36 to the right, and the gear 36 engages a gear 35. A motor which drives the gear 35 is operated via a switch when a cassette is loaded and therefore gives a displacement to the cassette 12 within a tray held by a stopper and a hook 28 to a prescribed position. In this case, the roll 38 presses the left side 23b of the part 23 to move the lever 22 to the right to interlock the above-mentioned stopper and hook 28.

Further, a spring is stretched between the left end of the f4 slide lever board in the drawing and the middle part of the f3 slide lever U. Furthermore, a gripping portion I of the interlocking lever 69 is formed on the lower side of the slide lever board of the second embodiment. Here, the interlocking lever mallet positions a pinch roller or a magnetic head (not shown) at a predetermined recording/reproducing position by displacement to the right in the drawing. ■Is it a lock lever? As shown in Fig. 2, it is located between the middle slide lever ② and the middle 4 slide lever ②, and its right end is supported by a support shaft 1 so that the main body nIJHC can rotate.

A notch 1a is provided at the bottom of the tip m of this lock lever, and the driving bottle can mounted on the slide lever 61 of f4 engages here k. Further, its upper side is slidably connected to a lock bin mounted on the fl slide lever αη. Furthermore, a notch line that can be secured to the lock bin is provided on the upper side near the pivot end.

ffl is a locking mechanism that locks the return operation of each part due to the stored force of the spring 69, that is, the movement in the direction of ejecting the cassette a21.The structure will be described in detail below.

σD is a locking lever, the left end of which is rotatably supported by the support shaft (1υ side), and the long hole σ2 formed in the middle part is engaged with the support shaft (4n). It rotates within the range determined by this elongated hole σ4.A notch σJ is formed at the lower right end of the hole, and as shown in Fig. engages. +74142 suction lever, 11
As shown in the figure, the main body is attached to the support shaft σ51! It is rotatably supported on the side surface of 111, and its free end is connected to the locking lever f.
engages the tip of fυ. Moreover, the upper bent piece σ19 is
It faces the solenoid installed inside the solenoid, and is attracted downward as it is energized.

In Figure 11, 0'Ill is a normally open switch, which turns on when the cassette (Iz) is inserted into tray a3.
The drive motor M and solenoid ση are energized. As shown in FIG. 17, the energizing circuit for the solenoid ση is provided with a normally closed switch 1) in series with the above-mentioned normally open switch so as to artificially release the excitation of the solenoid ση.

In the above configuration? When the cassette oz is inserted into the tray a3 in the standby state shown in FIG. Hook example engages. The stopper (c) is IC? It is engaged with the slide lever device of 2,
its displacement to the right) t? The signal is transmitted to the slide lever unit No. 2, the slide lever aη of fl integrated therewith, and the starting lever circle, and similarly displaces them to the right. Therefore, the force of the slide lever f2 is displaced from the position shown in Figure 2 to the position shown in Figure 14, its lower side (23,) is removed from the drive q-ra (to), and the notch gear (to) is It can be rotated clockwise as shown. Also, the starting lever is at its tip (3
Since the o- presses the opposite bottle (9), the notch gear (to) is rotated clockwise, and ? As shown by 41El, the injection position with the gear (to) is reached. Here the gear (
The motor (M in Figure 2) that drives the cassette 03 is operated by the operation of the switch 03 when the cassette 1 is inserted into the tray 03. Therefore, what about the notched gear C@? When it reaches the meshing position shown in Figure 4, it engages with the rotating gear and rotates clockwise in the diagram. Due to the rotation of this notched gear shaft, the drive roller (to) is moved to the left side (2) of the bending part (to).
34), the slide lever of 'yp2 is driven to the right against the tension of the spring.

In addition, as shown in Figures 2 and 3, the drive roller (to) and the slide lever (3) that engage through the long hole
61) is also driven to the right against the tension of the spring 61).

Here, 1M! By moving the slide lever (to) of the recorder 2 to the right, the cassette 121 in the tray 0 held by the stopper (c) that engages with it and its hook (a) k moves to the right in the figure by kg. . That is, cassette a2
1 is sucked toward a predetermined position within the tray 1.

On the other hand, the aforementioned slide lever 5<, 2g also moves to the right in the diagram, but the slide lever 4, which is connected via the thorn, moves to the right due to the lock lever. movement is prevented. , ie.

Since the drive pins tI provided on the slide lever 53 of f4 are locked by the lock lever 12, and the upper side of the lock lever I3 is suppressed by the lock pin trowel provided on the slide lever αη of the It cannot be rotated and the drive bin cannot be unlocked.

Therefore, the spring 6119 stretched between the slide lever ring of %f3 and the slide lever ring of %f3 is separated, and stores the operating force to the right of the slide lever ring of %f3.

Here, the lock bin vjI holding down the upper side of the lock lever is the cassette! It moves to the right in the figure together with the slide lever aη of 1 which is interlocked with the suction operation of 121. When the cassette 0 reaches a predetermined position in the tray a3, the lock bin also reaches the notch on the lock lever 6z. As a result, the lock lever 1m can be rotated upward, and due to the strong tension stored in the spring, it is flipped upward via the drive pin as shown in Figure 611J and >7.

This behavior causes ? Slide lever 4 becomes free and moves to the right by the tension of spring 6.

The guide bin @ that engages with the six cam grooves by moving the slide lever (toward) of f4 to the right is shown in Fig. 16? 7
As shown in the figure, the tray 0 that is integrated with this is pushed down, and the cassette in this tray Q3 is pushed down. 13 into a predetermined recording/reproducing t.

Furthermore, as the slide lever (to) of f4 moves, the interlocking lever 69 also moves in the same direction, and the pinch roller and magnetic head (not shown) are dropped into the predetermined position W of the cassette C115.
, so that recording or playback is possible.

When the notched gear (A) is rotated by a predetermined angle, as shown in Fig. 16, ?
71? As shown by l, the mesh with the gear (to) is released, but at this time, the lock pin (49) provided on the slide lever 3 has reached the lower end of the locking lever ffn. The tip of the lock pin 4 receives a downward force from the solenoid through the suction lever σ from the time the switch turns on, and immediately descends as the lock pin 4 faces the notch O formed at the tip. and lock it as shown in Figure 27.Therefore,
? No. 3 slide lever will not return to the left. Further, as shown in Fig. f7, the lock lever n is flipped upward by the rightward movement of the drive bin, and is in a state in which it cannot be rotated downward. For this reason,
The lock bin device held in the notch 1'7) on the upper side is also locked in the same state as p4, and the slide levers 1 and 2, which are integrated with this, do not return to the left side in the figure. Maintain this status.

In addition, in this state, the notched gear (support) is biased clockwise in the figure as the force of the leaf spring is applied to the cam piece G■ provided on the support shaft, which prevents the notched gear (support) from meshing with the gear (to). Rotate slightly to release completely.

Next, the case where the cassette 07J is taken out will be explained.

first,? Open the normally closed switch shown in Figure 7 to de-energize the solenoid. Therefore, the tip of the locking lever σD returns upward and disengages from the locking mechanism, so that the slide lever 1-3 (441 is connected to the stored spring 5
The tension in 1) causes it to return to the left.

Also, along with this? The slide lever No. 4 also returns to the left in the same manner. Due to this leftward movement of the slide lever 63 of f4, the interlocking lever 6I and the guide bin @ that engages with the cam groove 69 operate in the opposite manner to the above case, moving the cassette (13) upward from the predetermined recording/reproducing position. Furthermore, by moving the slide lever 0 of ?4 to the left, the lock lever IZ also returns to the horizontal state shown in Fig. The 1fl slide lever a7) and the integrated 2nd slide lever I221 return to the left by the tension exerted by the spring 12 [HCl.

Tray a3 is then
The inner cassette f13 is moved in the ejection direction. Furthermore, when the slide lever of the tree 3 is returned to its original state, the notched gear C rotates clockwise through the 70 slotted hole (4 mallets) and enters the standby state shown in Fig. 12.

Here, in the present invention, when the cassette H is attached, the energy for release (spring force) is also stored at the same time, but since the driving force of the motor is used, there is no burden on the user and The cassette can be installed reliably by operating force. In addition, if a disconnection occurs in the power supply system, the solenoid ffη is demagnetized and the cassette α2 is automatically released and the standby state is established. Therefore, the pinch roller is not left in the crimped state, and the pinch roller is deformed. can be stopped.

Since the displacement of each slide member can be made the same, it can be arranged in a small space and the overall size can be reduced. Furthermore, since no load is applied to the mounting motor after mounting is completed, the capstan and take-up reel motor can be used in common.

〔Effect of the invention〕

As described above, according to the present invention, it is possible to obtain a tape player in which a cassette can be reliably loaded with a light operating force, the overall size can be reduced, and a motor can be shared.
