Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the creation of a cassette cartridge player,
The loaded cassette cartridge can be smoothly and automatically carried to the loading position by a compact mechanism, and in particular, there is no need to arrange a complicated and large loading mechanism on the cartridge holder. This type of cartridge player, which is used as in-vehicle equipment, can be made smaller and thinner by performing a preferable cartridge loading operation, and also achieves a smooth loading/unloading operation by balancing the operating force during loading and ejecting. The present invention aims to provide a cartridge player that can perform the following operations.

As tape packs, so-called cassette-type cartridges (hereinafter simply referred to as ``cassettes'' are used because they have advantages such as being 4-inch and thin packs, and are the mainstream in practical use today. Various types of breakers for playback or recording have been proposed and put into practical use.

However, a preferred type of cassette player is an automatic suction type, in which the operator pushes the cassette to an intermediate position leading to the loading position, and then the cassette is automatically carried to the bag loading position. This type of cassette has the great advantage of avoiding the difficulty of pushing the cassette deep into the insertion slot with the operator's fingers, thereby achieving smooth insertion. However, the mechanism to realize such an automatic suction system inevitably needs to be large, and in particular, a bar, link, spring material, etc. must be provided over the entire top surface of the holder that holds the loaded cassette. Therefore, the player has no choice but to be large, especially thick. The fact that the cassette player is so large and thick not only results in a lot of material loss, but also because these players are often used in vehicles, so it is necessary to install it inside the vehicle, such as in the driver's cab. This requires a large amount of space, and is not preferable in terms of weight and other considerations. Furthermore, when using the automatic suction system as described above, it is necessary to store energy for pulling out the cassette horizontally and ejecting it when ejecting, and therefore the ejecting operation force is large. In particular, it is difficult to apply this eject operating force effectively because it is applied to a small push-button knob with a single fingertip, and therefore, the bag release operation of such a player is not necessarily smooth. It has a different forehead orientation. The present invention was devised through repeated research to eliminate the disadvantages of cassette players in accordance with the above-mentioned conventional motion suction system. The above-mentioned automatic suction operation is realized only by a relatively short and compact section, and therefore, the charging operation member facing on the cassette holder is merely a locking section, increasing the thickness of the player. There is no such loading operation member, and the eject spring is energized during the cassette loading process, and the eject operation is simply unlocking.

To explain a specific embodiment of the present invention as shown in the attached drawings, a folded part 101 is formed on the front side of one side of the main plywood 100, and one end is placed on the folded part 101a of this folded part 101. The auxiliary deck 110 attached by overlapping has a plate shape elongated toward the back, and the tip thereof is a bent portion 111 that hangs downward, and this bent portion 11

The cassette holder 55 is flexibly connected to the tip of the rotating frame 50, that is, the cassette holder 55 is energized to be pulled down to the tip of the rotating frame 50. The target connection of the cassette holder 5 is such that it protrudes sufficiently toward the front from the tip 50a of the rotating frame 50, and extends to the pivot point 51 of the rotating frame 50 at the back.
A bulging seat 58 whose height slightly exceeds the thickness of the tip of the rotating frame 50 is formed in the middle of the rotating frame 50, and a fixed plate 54 is mounted on the bulging seat 58 so that its negative side 54a is connected to the tip 50a of the rotating frame 50.
The upper portion of the cassette holder 55 is protruded so as to slightly cover the top and is fixed with stoppers 59, 59, and is located in front of the bulging seat 58 of the cassette holder 55 with respect to the most hole-shaped perforation 57 formed on the distal end side of the rotating frame 50. The engaging protrusion 56 formed by folding the cassette holder 55 and the rotary frame tip 50e is engaged with each other.
The rotating frame is secured within the limit of the gap created between the lower surface of the fixed plate 54 and the upper surface of the portion of the cassette holder 55 in front of the bulging seat 58 due to the expansion of the bulging seat 58. A bendable relationship is achieved between the tip portion 50a and the cassette holder 55. The auxiliary deck 11 is located on the side of the cassette loading space 80 as described above.

The main slide plate 3 and the sub-slide plate 4 are attached to a fastening portion 3 formed on the other side of the main slide plate 3.
7 and a fastening portion 47 formed at the base end of the sub-sliding plate 4 are provided with tension springs 10 to connect them, but the sub-sliding plate 4 has two engaging parts at its intermediate portion and on the distal end side. hole 41,
42 is provided along its length, and another L-shaped engagement hole 43 is bored between the engagement holes 41 and 42 in the middle of the engagement holes 41 and 42. A locking protrusion 44 is provided on the inside of the bent corner of the engagement hole 43 in the shape of a mountain. The engaging element 115 on the auxiliary deck 110 is engaged with the first engaging hole 41, and the L-shaped one of the suction movement plate 7 is engaged with the second engaging hole 42. A shaft 72 on the auxiliary deck 110 inserted into the bent corner, the shaft 72 forming a collar portion 74 between it and the auxiliary deck 110 as shown in FIG. L
Engaged with the shape engagement hole 43 is a latch 81 provided at the tip of the interlocking link 8, and a tension spring 82 is provided between the pivot shaft 113 and the latch 81. At the same time, the base end of the interlocking link 8 and the distal end of the suction interlocking plate 7 are rotatably connected by a lotus silk pivot 73. The details of each member constituting the eject operation mechanism described above are as follows: The eject lever 2 has an operation button 20 attached to its base end, and a guide hole 201 formed along its length is a sliding sliding plate. It is configured so that it can be slid in the length direction by engaging with a retainer 140 protruded on the bottom surface of the retainer 14, and furthermore, the retainer 22 formed at the tip thereof and the switching rotary plate 14 A spring 23 is stretched between the main eject plate 9 and the mounting shaft 141, and an engagement groove 90 is formed by cutting into the base end of the main eject plate 9 on the surface side at a position near the fastening portion 22. An engaging member 24 is provided in a protruding manner.

As can be seen from FIGS. 4 and 5, the main eject plate 9 has an extended portion 9a formed on one side extending long to form a switch operating portion 91. However, a cam portion 92 for head plate switching operation is formed on the side green at a position forward of the deep part of the engagement groove 90 as described above, and is engaged with the head plate 15 to connect it to the cassette. A trochanter 25 for advancing and retracting the mounting castle 80 is faced. Further, a return spring 94 is provided between a fixed seat 93 and an auxiliary deck 110, which are formed by folding up the intermediate portion of the main project plate 9, and a protrusion 95 is provided at a position close to the fixed seat 93. The actuating piece 16 is formed so that it acts on the engaging protrusion 164 of the actuating piece 16 provided on the auxiliary deck 110, so that when the main reject plate 9 is pushed in, the free end side of the actuating piece 16 is pushed inward. Furthermore, the protrusion 9
Another protrusion 96 is provided on the upper surface at a position inside the eject linking piece 13, and the protrusion 96 moves to follow the protruding cam part 132 of the eject interlocking piece 13, and also engages and disengages with the engagement recess 137 thereof. The retainer 38 on the bottom surface of the main slide plate 3 of the above-mentioned cut-in operation mechanism can be clearly seen with reference to FIGS. 2 and 4 when the main slide plate 3 is pulled out and in the process of being pushed in. However, when the main slide plate 3 is completely pushed in, it becomes connected to the engaging portion 135 of the eject movement piece 13 as shown in FIG. , therefore, during the slight pushing process from this state, the eject interlocking piece 13
Since the retainer 38 is received in the notch 136 of the eject interlocking piece 13, there is no problem in rotating the eject linking piece 13 about the pivot 113. Furthermore, due to the rolling of the coin-like eject interlocking piece 13, the protrusion 96 of the main eject plate 9, which was engaged with the engaging recess 137 of the eject interlocking piece 13 in the state shown in FIG. Matching recess 137
As the main eject plate 9 moves back as shown in FIG. The rotational state shown in FIG. 5 is precisely formed. The operating piece 16 is attached to the auxiliary deck 11 via the Matsuko 16, and has an extension 161 formed at its tip that engages with the retainer 81 in the movement link 8 of the bag insertion mechanism described above, and a fixed seat 162. A tension spring 163 is arranged between the auxiliary deck 110 and the fourth
The main projecting plate 9 is provided so as to be able to move back to the state shown in the figure, but as described above, the engaging protrusion 164 is formed on the proximal end side, so that when the main project plate 9 moves forward, it is rotated as shown in Fig. 5. The retainer 81 is released from the locking protrusion 44, and the sub-sliding plate 4 is moved back by the tensile force of the spring 11, and the protrusion 96
After passing through, the state shown in FIG. 4 is restored again. A configuration for dropping the cassette 150 that has been sucked deep into the cassette loading space 80 into the playback position is shown in FIGS. 6 and 7. That is, as described above, the base portion 50a, which is bent and protruded in an L shape on the } side of the rotating frame 50, has a rail portion 170 bent in an F-shape at the tip thereof.
A guide piece 17 is fixed thereto, and a downwardly inclined side 50b is provided opposite to the distal end of the base 50a. The trochanter 97 provided as shown in the figure is exposed, and when the main eject plate 9 moves back by the spring 94, the trochanter 97 enters the oblique side 50b from the state of being joined to the lower side of the base 50a. As a result, the rotating frame 50 is gradually tilted downward by the action of the spring 53.
When the trochanter 97 separates from the neck oblique side 50b, the rail portion I
The upper surface of the TO is pushed down, and the front side of the rotating frame 50 is pushed down sufficiently with the pins 51, 51 as the center, so that the cassette holder 55, which is flexibly connected to the tip of the nuclear rotating frame 50, is in a horizontal state. It is dropped onto the main plywood 100 as it is and set at the regeneration position, and this regeneration state 0 is the spring 53.
It is held accurately by something like this. As the main eject plate 9 advances during eject operation, the trochanter 97 moves forward on the rail portion 170 (moves from the solid line position to the imaginary line position in FIG. 6), thereby utilizing the rail portion 170 of the trochanter 97. Main plywood 1 of the cassette holder 55
00 is released, and then this trochanter 97 enters the lower side of the oblique side 50b and moves further forward, thereby pushing up the rotating frame 50 by the tensile force of the spring 53, and then pushing up the rotating frame 50, 50c, the rotary frame 50 is pulled up, and the cassette holder 55 and cassette 150 are pulled up and held at a constant height position as shown by the imaginary lines in FIG. The configurations shown in FIGS. 6 and 7 can be modified and implemented as shown in FIG. 8 depending on the situation.

That is, the trochanter 97 as described above is attached to the base 50a of the rotating frame 50, and the heights of the front and rear parts are different from each other with respect to the folded part 9b formed on the side of the main eject plate 9. A series of guide holes 9c are provided in which the horizontal parts 9d and 9d are connected by an inclined part 9e, and the front trochanter 97 is iron-bagged with respect to the guide holes 9c. If this is done, the guide piece 7 in FIGS. 6 and 7 is not required, and the rotating frame 50 can be operated in exactly the same manner as described above by operating the main ejection plate 9, and the cassette holder 55 and the cassette 150 to the playback position and the pulling up of the cassette 150 into a standby state. In the illustrated example, 200 is a motor, and it is generally known that the motor 200 drives a flywheel (therefore its capstan), a reel shaft, etc. The arrangement of the return operation mechanism and others is as shown in the figure. As is generally known, the cassette 150 includes two reels, and a tape is wound between these reels. It goes without saying that the capstan, which is attached between the capstan and the pinch roller, passes through the front of the reproducing head by the constant rotation of the capstan due to the rotation of the flywheel, and achieves the desired reproduction, as shown in Figure 1. The mechanism is housed within a suitable cover. To explain the operation of the device according to the present invention as described above, the cassette 150 is loaded into the cassette holder 55 with its playback end face 151 facing the side wall plate 102 into the cassette loading space 8, and the cassette 150 is inserted into the cassette loading space 8, and the cassette 150 has a U-shaped cross section. Clamping piece 1
6, the front end of the cassette 150 on the playback end surface 151 side is received to form a state in which several cassettes are placed.In this state, when the cassette 150 is guided to the cassette holder 55 and pushed further, the main slide plate 3 moves forward as shown in FIG. The front end of the accessory piece 6 is joined to the engaging part 31 and is pushed together with the cassette 150, and as the main slide plate 3 moves forward, the engaging pin 71 of the suction interlocking plate 7 is moved to the guide. Hole 35
The suction interlocking plate 7 is rotated around the ball 72 until it reaches the position of the engagement pin 71' shown by the dotted line, and when it is pushed in further, the As shown by the dotted line, the engagement pin 72'' is pushed out of the guide hole 35, and during this series of movements, the suction movement plate 7 moves approximately 1200 mm as shown in the figure.
The above will be repeated.

During the rotation process of the suction interlocking plate 7, the connection pivot 73 provided at the other end rotates from 73' to 73 as shown by the arrow.
'', and in the process of reaching the lotus-striped pivot 73', the retainer 81 provided at the tip of the interlocking link 8 engages with the locking protrusion 44 and guides the sub-slide plate 4. hole 41,
Within the limit of 42, it is pushed forward (to the left in the figure) as shown by the upper arrow a in FIG. Kashiwako 7
1 rotates from 71' to 71'', the spring 8
The retainer 81 and the retainer protrusion 44 remain locked due to the tensile force shown in FIG. It moves backward as indicated by the lower arrow b shown for explanation. The above-mentioned forward movement of the main slide plate 3 is performed by extending the relatively weak spring 10, but the preceding process is the process in which the engagement pin 71 rotates to the position indicated by 71' (therefore, In addition, in the process until the connecting pivot 73 reaches the position 73', the retainer 81 pushes back the sub-sliding plate 4 against the relatively strong elasticity of the spring 11 as indicated by the arrow a in the explanation above. , the springs 10 and 11 act against the respective elastic forces, but since this process is the initial loading process with the cassette 150 fully protruding from the insertion opening of the player, no effective pushing force is applied. It can be pushed in with almost no trouble. However, the subsequent process in which the engagement pin 71 rotates from the position 71' to the position 71'' (the lotus pivot 73 from the position 73' to the position 73'') is the final stage of loading the cassette, and the cassette protrudes from the player insertion port. Although the end of the cassette 150 is short and small, and it is a process that requires pushing the player into the appropriate depth from the player insertion slot, this process is the process shown by the above-mentioned arrow b, and the secondary part moved as shown by the arrow a. After the force is accumulated in the relatively strong springs 11 by the slide plate 4, the stored force is released, thereby allowing the comparatively weak springs 10 to extend, while the restoring action of the strong springs 11 automatically moves the main slide plate. 3 and the cassette 150 will be inhaled deep into the body. It is clear that the extension of the spring 10 is an accumulation of eject operating force with respect to the eject plate on which it is disposed, and therefore, at the time of ejecting, the eject operation can be performed simply by releasing the locked state. In the process of advancing the main slide plate 3 as described above, the grandchild 38 provided on its lower surface moves forward as shown by the arrow in FIG.
3, the locking portion 135 of the protrusion 96 is pressed.
As described above, the main eject plate 9 having the protrusion 96 is released from the engagement with the protrusion 96.
It is also clear from what has already been described that the state shown in FIG. 5 is formed by being moved back with a strong tensile force of 4.

However, it is clear that when the main eject plate 9 is reinstalled as described above, its trochanter 97 moves to the left in FIGS. The front side of the rotating frame 50 is dropped downward, so that the rotating frame 50
A cassette holder 55 flexibly connected to the front end of the cassette holder 55 is set at a playback position on the main plywood 100 together with the received cassette.

At the time of ejecting, the above-mentioned operating relationships are essentially performed in the opposite order. To explain the details, the main eject plate 9 is moved from the position shown by the solid line in FIG. 5 to the eject lever 2. As a result, the projection 96 moves forward as shown by the imaginary line, so that the protrusion 96 engages the engagement recess 1.
37, the main slide plate 3 having the latch 38 that has been engaged with the engagement recess 136 is pulled out by the tensile force of the spring 10, and the latch 38 moves back along the straight edge 134 to interlock with the eject. The piece 13 is returned from the state shown in FIG. 5 to the state shown in FIG. 4.

Also, due to the return movement of the main slide plate 3, the position of the engagement pin 71 of the suction movement plate 7 in FIG. The connection pivot 73 becomes 73″ → 73′ → 73,
In the process from 73'' to 73', the retainer 81 has come off the locking protrusion 44 in the L-shaped engagement hole 43, but while returning from 73' to the 73 position, the spring 82 is As a result of this action, this retainer 81 is retained by the locking protrusion 44 and returned to its original state.The rotary frame 50 is operated by the rotor 97 in the opposite manner to that described above as shown in FIGS. 6 and 7. It is clear that the cassette and cassette holder that had been dropped onto the main plywood board 100 can be pulled up and put into a standby state by doing this.In accordance with the present invention as explained above, the player is loaded from the player insertion port. It is clear that the cassettes can be transported deep into the interior by an automatic suction system, and its structure is such that, as shown in Figures 1 and 2, there is a bag loading operation mechanism and a reject operation on the cassette loading section. This type of player can be made sufficiently thin due to the fact that there is virtually no material constituting the mechanism, and in addition, the eject operating force is stored during the cassette loading process. As a result, the invention has the advantage of reducing the ejector operating force and improving the overall operability to facilitate smooth use.This invention is industrially very effective.
