PURPOSE:To press a cassette with a sufficiently strong force in the position where the cassette is loaded and to move the cassette surely and efficiently in horizontal and vertical directions. CONSTITUTION:When a cassette 1 is inserted to a cassette receiving base 2 from the font, a motor is rotated, and the rotation is transmitted from a worm 17 to a worm gear 15, and a shaking lever 23 is turned through a pinion 18, a crank pin 21, etc., and a cassette receiving base supporting shaft 3 received in a supporting shaft receiving groove 24 is moved in the horizontal direction along the horizontal part of an L-form groove 5. Consequently, the cassette receiving base 2 is moved in the horizontal direction, namely, to the depth in accordance with this movement of the supporting shaft 3. When the shaking lever 23 is turned furthermore, the cassette receiving base supporting shaft 3 is moved along the vertical part of the L-form groove 5, and the fall of a slider 7 is accompanied because of the state where the cassette receiving base supporting shaft 3 and the second supporting shaft 6 are received in a receiving hole 8 of the slider 7 together. At this time, since the slider 7 is moved along a guide hole 11 by guide pins 9 and 10, its horizontal attitude is held as it is.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cassette device for use in devices that handle cassettes, such as video or audio equipment, and particularly relates to a so-called front-loading type cassette spinal monitoring device.

For example, in recent cassette tape recorders, the operation surface is equipped with many buttons and knobs for various adjustments and program reservation timers, indicator lamps, and other displays. Therefore, a relatively wide l1lI is required for its operation surface. Furthermore, it is advantageous to place a TV or speaker box on top of such a tape recorder, which is advantageous in making effective use of indoor space, and a design for this purpose is also required. In order to meet this requirement, it is necessary to bring such an operating surface to the front of the tape recorder.Furthermore, as described above, a front-loading method is proposed as a method that satisfies the wide range of demands for such an operating surface. is illustrated.

Front-loading system makes cassettes cheap.
The cassette is inserted through a relatively long and narrow insertion opening at the front of the cassette, and is automatically loaded to the tape recording or playback position. That is, in this front day-fing method, after the cassette is inserted from the insertion slot, it is first moved horizontally to negative h, then vertically lowered, and fitted onto the reel shaft. be.

Conventionally, various types of structures have been proposed as a latch mechanism that couples such a front loading system, but there are still some points to be improved. In other words, the structure is complicated because it requires two kinds of operations to move the cassette in the horizontal direction and in the vertical direction. Furthermore, the drive mechanism becomes complicated in order to transmit the movement of the second grade steel to the cassette. Such complication on the bridge increases the overall size of the wheel load, which is undesirable. Also,
At the recording or playback position of the cassette, the cassette must be held securely, and this requires a certain amount of force to press the cassette, but the mechanism for this is also complicated. bring about change.

Furthermore, with the front rope ink method, the horizontal movement distance is relatively impressive, 611, but in order to allow the cassette to move over such a long distance, a mechanism that performs a certain amount of movement is required. The relatively wide range of operation of the mechanism also contributes to the large size of such parts.

Therefore, the main objective of this invention is to provide an efficient configuration;
The object of the present invention is to provide a cassette @1 vehicle that can eliminate the above-mentioned drawbacks.

According to this invention, first, when the cassette is attached to the 6-position (6-position), it becomes possible to press the cassette with a sufficiently large force. It can be carried out quickly and efficiently.If necessary, a long horizontal movement distance can be freely obtained.

[The arrangement, shape, and dimensions of each element constituting the cassette i@ device, as well as the amount of movement and h of each element, can be freely designed in various ways.

Other objects and features of the invention will become apparent from the detailed description given below.

Figures 1 to 31! 1I shows one embodiment of this invention, 1K1 is the right side of the cassette ring pot, and the 2nd
The figure is also the correct Ell, and the third figure is the cassette mouse Iw.
k is also a side view.

The schematically illustrated cassette 1 is mounted on a cassette holder 2.
The cassette is moved within the cassette barrel device while being received and held by the cassette. Cassette i-* 4] Unit 2
On each side of the cassette receiver, a stand support shaft 3 is provided to protrude. In this device, the cassette holder is placed at the center of the stand 2f, and most of the elements are arranged on the left and right sides, so we will explain the configuration of one of these sets, especially the right side, and explain the other side, that is, the left side. are given similar reference numerals and their description will be omitted. The support shaft 3 of the cassette holder is relatively long and accommodates an L-shaped groove 5 provided in the side wall 4 of the substrate. this[
The shaped groove 5 serves as a guide path for guiding the movement of the cassette holder, the stand support shaft 3, the cassette holder, the pedestal 2, and the cassette 1. Further, a second support shaft 6 is provided on each side of the cassette holder holder 2 so as to protrude from a position different from the cassette holder holder support shaft 3 mentioned above. This JIII2 support shaft 6
is relatively short and does not penetrate the substrate 114. The support shaft 6 of this machine 2 and the aforementioned cassette holder support shaft 3 are positioned so that their positions in the field direction are the same. , these are on the board side! The slider 7 is configured to be received in a receiving opening 8 of a slider 7 disposed inside the slider 4. The receiving port 8 extends horizontally in the front direction in this embodiment. An upper guide bin 9 and a lower guide bin 10 are provided protruding from each side of the slider 7, respectively. The upper and lower guide bins 9 and 10 are received in guide holes 11 extending vertically in the board-K14, whereby the slider 7 is guided in the vertical direction while being held in its horizontal position. be done. A spring 13 is stretched between the lower guide pin 10 and the pin 12 fixedly numbered on the board side I14.
The slider 7 is always urged to be displaced upward.

Both ends of the drive shaft 14 are supported by the right board side wall 4.4, and one drive shaft 14 is provided so as to be able to rotate once. A worm gear 15 is fixed to the drive shaft 14 at an appropriate position on the drive shaft 4. motor 16
The rotation of A-arm 1 which meshes with this worm gear 15
7 to the 11 4-mgya 15 and the drive shut 14. Both ends of the drive shaft 14 are on each board side! 4
The pinion 9-18 extends through the drive shaft 14, and a pinion 18 is attached thereto.The pinion 9-18 rotates once integrally with the drive shaft 14.

A relatively large diameter gear 20 is provided which meshes with piniote J-8 and rotates about a gear shaft 19. A crank pin 21 is numbered and protrudes from the side surface of the gear 20. A lift lever 23 rotatably supported around a fulcrum 22 located near the gear 20 and away from the gear shaft 19 is provided on the outside of the substrate side wall 4 . The lever 23 is approximately L-shaped, and a support shaft receiving groove 24 and a crank pin receiving groove 25 are formed at each end thereof, respectively. The respective cassette receivers 124 and 25 slidably receive the table support shaft 3 and the crank bin 21, respectively.

Next, the operation of the embodiment shown in FIGS. 1 to 3 will be explained.

First, the user inserts the cassette 1 into the cassette holder 2 from the front. In response to this, insertion of the cassette 1 is detected, a switch (not shown) is turned on, and the motor 16 is rotated once. In accordance with the rotation of this motor, rotation is transmitted from the worm 17 to the worm gear 15, and the left and right pinions 18, 18 are rotated simultaneously and at the same rotational speed via the drive shaft 14.

Then, the gear 20 that meshes with the pinion 18 is connected to the arrow 26
rotated in the direction In response to the rotation of the gear 20, the crank bin 21 is displaced along an arcuate trajectory centered on the gear shaft 19. Therefore, the swinging lever 23 has a crank pin receiving hole 25 that receives this crank bin 21.
is rotated clockwise in FIG. 1 about the fulcrum 22, resulting in the state shown in FIG. 3. When the third @ state is reached, the motor 16 is switched off, and the gear 20 and the like are stopped at that position.

By such rotation of the swing lever 23, the following operations of the cassette receiver on the stand 2 are achieved. First, the cassette support shaft 3 received in the support shaft receiving groove 24 is moved in the horizontal direction along the horizontal inner portion of the L-shaped groove 5. Accordingly, the cassette holder and the stand 2 are also moved in the horizontal direction, that is, in the negative direction. Second
The support shaft 6 of the slider 7 also moves to the height h of the receiving opening 8 of the slider 7. Then, the cassette support base support shaft 3 passes through the horizontal portion of the L-shaped groove 5 and attempts to reach the vertical portion. At this time, the cassette holder is in a state where the stand support shaft 3 is also received in the receiving opening 8 of the slider 7. Further, when the swing lever 23 rotates, the cassette holder support shaft 3 moves along the vertical portion of the L-shaped groove 5. This movement accompanies the lowering of the slider 7, since the cassette receiver is in a state where both the base support shaft 3 and the second support shaft 6 are already received in the receptacle 08 of the slider 7. At this time, the slider 7 is moved along the inner hole 11 by the guide pin 9.10, so that its horizontal position is not changed. In addition to this, since the left and right II elements of this section are operated synchronously, the cassette holder platform 2 also descends while maintaining the horizontal position of the cassette holder. (11) Finally, when the sword Ly+1 is brought to the position shown in FIG. 3, the reel shaft is inserted into the sword Ly+1, and it enters the recording or reproducing state.
□ What should be noted in the state shown in Fig. 13 is the consideration regarding the transmission of motion from the crank bin 21 to the swing lever 23, and conversely, when the motion is transmitted from the swing lever 23 to the crank bin 21. This means that the dead center state when assuming . If the power is replaced, the drive force transmitted to the swing lever 23 via the crank bin 21 is increased by the gear 20 so that the cassette holder is amplified near the lowest point when the table 2 moves vertically. The rotation of the swing lever 23 with respect to the rotation angle is smaller than the rotation of the vertical self-movable part other than in the vicinity of the lowest point. This means that this crank bin 21
via the swing lever 23 (the cassette holder is connected to the base support shaft 3).
This means that the h transmitted to the cassette 1 is the largest, and therefore the cassette 1 is strongly pressed to a predetermined recording or playback position, which has the effect of stabilizing the cassette 1. be.

Next, when the recording or playback of the tape in the cassette 1 is finished, the motor 16 is turned on again when this is sensed or when it is desired to end such recording or playback state. In response, the gear 20 rotates again in the same direction, that is, in the direction of arrow 26, and the crank bin 21
is displaced clockwise from the 311th position. In response to this, the swing lever 23 is now rotated counterclockwise about the fulcrum 22 in FIG. The vertical portion is raised, and the biasing force of the spring 13 also acts to raise the slider 7 along with this movement. And the cassette holder is the stand support shaft 3
When the bale approaches the horizontal part of the L-shaped groove 5, the cassette holder and the stand support shaft 3 move along the horizontal part of the L-shaped groove 5, and the second support shaft 6 moves along the horizontal part of the L-shaped groove 5. 1ll18, and the cassette holder 2 moves horizontally in the direction of the cassette holder. Then, the state returns to the state shown in FIG.

At this point, motor 16 is turned off.

14- Thus, in this embodiment, the motor 16 is rotated in the -Rh direction, and its switch is turned on and off depending on the cassette 1.
If the loading and unloading of the cassettes is carried out in accordance with the positions of the cassettes, it becomes possible to automate the loading and unloading of the cassettes as desired according to a predetermined procedure.

FIGS. 4 to 9 show other embodiments of the invention!
Fig. II4 is a right side view of the cassette cylinder, Fig. 5 is a front view, Fig. 6 is a right side view after the cassette @II, Fig. 7 is a rear view, and Fig. FIG. 8 is a right side view as well, but has been cut away appropriately to clearly show the positional relationship of each component 11IA, and FIG. 9 is a plan view of the cassette holder at its base.

For example, in a video tape recorder, after the cassette is loaded in the recording or playback position, the tape in the cassette is automatically wound around a cylinder with a rotating head. Around the periphery, tape blades, drive mechanisms, etc. are arranged over a relatively wide area IIIi. Therefore, it is usually necessary to move the cassette over a considerable horizontal distance from the position where the user inserts the cassette from the operation surface until the cassette is mounted at the recording or playback position.

In addition, recently, for operation of video tape recorders,
Many mechanical or electrical devices are provided for operating the program reservation timer and the like, and therefore, the space for installing such devices is used. This also causes the horizontal distance from the cassette insertion port to the noodle monitoring position to become long. For example, the cassette must be moved 80 to 100 distances horizontally and then T-dropped vertically. Moreover, in such a videotape recorder, it is preferable that the cabinet has a small dimension because a television or the like can be placed on top of the cabinet. Other embodiments of the invention described herein meet these needs.

This example is 1. Although this embodiment is similar in principle to the embodiments shown in FIGS. In the following, the reference numbers used in the above-mentioned tIAf14 will be used for corresponding parts in the same manner, and the explanation will be focused on the differences.

First, the motor 16 is not rotated in the - direction, but is rotated in opposite directions when the cassette 1 is loaded and when it is ejected.

The swinging lever 23 is composed of an outer swinging lever 23a and an inner swinging lever 23b, which are arranged on top of each other. Both are movably supported by a common fulcrum 22. Between the bin 27 provided on the outer swinging lever 23a and the locking piece 28 formed on the inner swinging lever 23b,
A tension spring 29 is connected, and the outer lifting lever 23a and the inner swinging lever 23b are always biased in a direction in which they blur into each other.

Further, the pinion 18 and the gear 20 are each JlI

The crank pin 21 provided on the side surface of the gear 20 passes through the C-shaped groove 30 provided on the base plate side 14 and connects to the base side crab 4.
extends to the outside. The outer swing lever 23a is provided with a 17-crankbin receiving groove 25 for receiving the crank pin 21. As best shown in FIGS. 4m and 6, the side edge of the inward lift lever 23b can be seen within the crank bin receiving groove 25. Particularly, in the state shown in FIG. 8, the fact that a part of the edge of the inner swinging lever 23b has a sloped side edge 31 has an important meaning as described by Tawara. This sloped side edge 31 is positioned so as to be visible within the crankbin receptacle 125.

The outer swinging lever 23a is provided with a support bearing receptacle 24, but this and a crank bin receptacle 25 are located on the same side of the fulcrum 22, and the support bearing receptacle 24 is located from the fulcrum 22. The distance is selected to be longer than the distance from the fulcrum 22 to the crank bin receptacle 25. this is,
Even if the crank pin 21 is in the first position within a relatively small range, the cassette holder allows the table support shaft 3 to be moved over a relatively long distance.

This means that the cassette holder allows the horizontal movement distance of the stand 2 to be longer, and therefore, this 18- theory @ has a larger wheel length than the above-mentioned embodiment in terms of the horizontal distance of the L-type 1111I5. hgh when something fancy is needed.

Further, in the state 4a, the receiving port 8 of the slider 7
Upper and lower rails 32 and 33 constituting an extension of are identified within the substrate side I14. This is because the cassette holder supports and guides the second support shaft 6 in the state 18411, since the horizontal movement distance of the table 2 is long. Similarly, the support shaft 3 of the cassette 1 is guided during its movement in the horizontal direction.

In addition, as shown in No. 9all, the cassette holder has a row 534.3 on the base support shaft 3 and the second support shaft 6.
5.36 are each rotatably mounted. low 53
4, the cassette holder is the stand support shaft 3 (01M45, upper and lower (1
)Le-)Ii32.33O, [[The movement along the entrance 8 is defined as a smooth movement 1. The row 535 allows the cassette support to smoothly move the table support shaft 3 within the support shaft receptacle 24. The O-ra 36 is connected to the upper and lower rails 3 of the second support shaft 6.
2.33 and the movement along the receiving line 8 should be smooth.

Characteristic parts of the operation of the embodiments shown in 1II4igI to 189al will be explained. From the state shown in Figure 4,
When the gear 20 rotates in the direction of the arrow 26, the crank bin 21 is moved by the outer swinging lever 23a and the inner lifting lever 2.
3b clockwise.

Accordingly, the cassette holder and stand support shaft 3 are L-shaped 115
When the cassette receiver moves through the horizontal portion and reaches the vertical portion, both the base support shaft 3 and the second support shaft 6 are located within the receiving opening 8 of the slider 7. Then, as shown in A, the cassette holder is guided by the vertical portion of the L-shaped groove 5 and the guide hole 11, and the cassette holder is moved to the position f! Descends in the direction of direct force.

The final state of this descent is shown in FIG. 16, and is also shown in FIG. 8 to supplement the explanation of this FIG. 6 state.

With reference to FIG. 6 and FIG. '8'', the crank bin 21
Since the outer swinging lever 23a comes to a dead end at the point where the cassette 1 is pressed into position, the inner swinging lever 23b is brought to the feat of slightly passing the outer lifting lever 23a. In this state, the tension spring 29 is slightly stretched, and a tensile force is applied to the external lifting lever 23a.

The inner swinging lever 23b is configured such that one turning force of the gear 20 is increased here in order to strongly press the cassette holder 2 to the recording or reproducing position shown in FIGS. 6 and 8. ing. That is, the crank pin 21 is in contact with the slope side edge 31 of the inner swing lever 23b, but in this state, compared to the rotation angle of the gear 20, the rotation of the inner swing lever 23b is... sham decreases, and therefore, the inner lever 23
The rotational force of b increases. As a result, a large force is obtained on the inner swinging lever 23b, and accordingly, a large force is also applied to the outer lifting lever 23a via the tension spring 29. Then, the cassette holder 2 is strongly pushed in at its recording or reproducing position.

21- The explanation of the operation from the cassette cylinder position to ejection is omitted, but it only follows the path of operation just described. That is, in this embodiment, in the opposite case, the motor 16 is rotated in the opposite direction, and the gear 20 returns to the state shown in arrow 37, a-r, and No. 4 IlI.

To summarize the two embodiments described above,
It can be said that it has the following characteristics or advantages.

Since motion is transmitted between the swing lever 23 and the gear 20 without any mechanical play, the cassette holder and stand 2 can be moved while always maintaining the desired posture in all directions. , and there will be no twisting during this movement that will impede harmony.

In addition, the cassette holder is a stepper that moves the table 2 from horizontal movement to vertical movement, and the cassette holder is provided with a slider 7 to maintain the horizontal position of the table 2. Since the means for guiding the vertical direction and the means for guiding in the vertical direction are substantially separated, the height dimension of such guiding means can be reduced. Also, since such a slider 7 is provided,
When moving in the horizontal direction, this movement progresses without any burden, and the rotational movement of the swing lever 23 smoothly transitions the movement from the horizontal direction to the vertical direction.

In addition, the fulcrum 22 of the swing lever 23 and the gear shaft 1 of the gear 20
By appropriately changing the relative positional relationship with 9 according to the purpose, the following design freedom can be achieved. That is, as in the embodiments of the 1st to 113th gardens, the motor 16 is rotated in only one direction and controlled on/off to perform the opposite operation of loading and ejecting the cassette 1f. I can do it. In the embodiments shown in FIGS. 4 to 9, a good horizontal movement distance is provided, and the cassette 1 is strongly pressed by the rotation of the same gear 20 only when the cassette 1 is at its recording or reproducing position. This can advantageously be achieved by means of a mounting 11 and a sliding lever 2. Also,
In the 4II to 9111th embodiments, although the horizontal movement distance thereof is increased, the swing lever 23
The contact angle between the cassette holder and the stand support shaft 3 is not so large, so the distribution of h is effective.
In addition, the dimension of the headrest in the longitudinal direction can be reduced.

In each of the above-mentioned embodiments, the mating lever 2
The crankbin 21 was used to obtain the rotational force of 3 from the 200 rotations of the gear. However, this is the next 1011th
It can also be replaced with the configuration shown in .

The 10th meter is a right side view of a further preferred embodiment of the present invention before the cassette is installed. In this solid example, transmission is performed using a cam. The above-mentioned embodiment can also be viewed as a road cam, and therefore, the above-mentioned embodiment can also be said to use a type of cam. In the embodiment shown in FIG. 10, a front cam is used. That is, the front cam 38 is mounted so as to be coaxial with and rotate integrally with the gear shaft 19 of the gear 20. The front cam 38 is provided with a groove 39 corresponding to the contour of the cam,
Come Follower 40 is here! Can be put in.

The small U-wa 40 is attached to the swing lever 23. Therefore, when the gear 20 is rotated and the front cam 38 is rotated once, the cam follower 40 is displaced along the full 39 contour, and the swing lever 23 is swung in response to this displacement. The subsequent operations coupled with the first shift of the vibration lever 23 are the same as those in the embodiments 1II to 311, so their explanation will be omitted.

101st! In the embodiment ll, the groove 3 of the front cam 38
If the shape of the lever 9 is adjusted appropriately, the rotation and speed of the lever 23 can be made as desired. For example, the cam follower 40 corresponding to the mounting position of the cassette
If the slope of the cam diagram at the position is set to zero or almost zero, a large turning force can be obtained by applying the grip lever 23.

Furthermore, in the embodiments shown in FIGS. 41II to 9, the cassette 1j is connected to the slider 7 only when its moving direction changes from the horizontal direction to the vertical direction, and is moved down together with the slider 7. Therefore, the structure becomes simple. Conventional similar mechanisms used a slider mechanism for the cassette 25 tray and the platform to move in the horizontal direction as well, but in this case, the mechanism for this purpose was large. However, all of these drawbacks are eliminated. In addition, in another conventional similar mechanism, two or three L-shaped grooves are used.
Some models prevent tilting when descending vertically by moving the support shaft along the
As in the 411th to 911th solid line examples, it is not possible to satisfy the requirements of increasing the horizontal displacement distance and decreasing the height dimension of the part.

Note that an embodiment shown in No. 1111 is also possible as having a type of slider similar to the above-described slider 7.

FIG. 11 is a right side view of an embodiment of the present invention in which the cassette is in the middle of mounting. The 1111th embodiment is the 4a
This is an example in which only the slider portion of the 911th embodiment is modified. Thus, for example, the 4th Il
Perform @@ of l1111II while comparing with I.

26- The cassette holder shown in FIG.
In FIG. 11, the cassette holder was provided at the same height as the table support shaft 3, but in FIG. Further, an engaging portion 41 and a cassette holder are attached to a relatively lower portion of the stand 2. In addition, the upper and lower rails 32.
33 extends further to the right in FIG. In order to receive the engaging portion 41, the substrate-! 4 is fitted with a vertical guide member 43' having an upwardly open receiving eye 42.

In this embodiment, in the cassette holder, the base support shaft 3 is
When moving in the horizontal part of the L-shaped groove 5, this cassette holder is connected to the support shaft 3 and the horizontal part of the L-shaped groove 5.
The horizontal position of the cassette holder 2 is maintained by the relationship between the support shaft 6 112 and the upper and lower rails 32,33. When the cassette support shaft 3 moves in the vertical direction of the L-shaped groove 5, the cassette support □support shaft 3
The cassette receiver maintains the horizontal position of the stand 2 due to the relationship between the vertical portion of the L-shaped groove 5 and the relationship between the engaging portion 41 and the receiving opening 42 .

In addition, in the description of each embodiment described above, the cassette holder was explained in the case where the table support shaft 3 was guided by the L-shaped groove 5, but this LW3 groove 5 was formed in the side wall 4 of the substrate. It doesn't have to be a hole. For example, inside the board side 114,
Two L-shaped rails are installed, and these two L-shaped rails are installed.
The groove formed in the groove (2) may be an L-shaped groove. Also, place the swing lever 23 on the board side! The arrangement relationship of each element may be changed, for example, by arranging the gear 20 on the inside of the board side 124 and the gear 20 provided on the outside of the board side 124.

Furthermore, in the example of the 10th WA, the front cam 38 was provided as a separate member from the gear 20, but the groove 3 of this front cam 38
9 may be provided directly on the side of the gear 20. In connection with this, in the example in which the crank pin 21 was provided, the crank pin 21 was provided directly on the side surface of the gear 20;
Such a rank pin may be provided on a disc, such as the front cam 38, that rotates uniaxially and integrally with the gear 20. In short, the groove of the rank pin and cam like this,
This means that it is only necessary that it be provided on a rotating surface that rotates coaxially and integrally with the gear 20.

As described above, according to the present invention, using a combination of a gear and a swinging lever that is rotated by the rotation of the gear,
Since the gear shaft of the gear and the fulcrum of the rocking lever are positioned at different positions, it is possible to give a degree of freedom in designing the transmission mechanism from the gear to the rocking lever. In other words, by simply rotating the gear in one direction, it is possible to perform operations in the opposite direction, such as loading and unloading a cassette, if necessary, and the cassette holder also requires a large horizontal movement distance for the table. This is also possible if necessary. Also,
The cassette holder is configured so that the driving force transmitted to the rocking lever is increased near the lowest point when the table moves vertically, so that the cassette is held at a predetermined position when the cassette is installed. This makes it possible to press firmly against the disc, allowing stable recording or playback. In addition, the force applied to such a cassette can be applied without the need for a special mechanism, which is advantageous for making the structure one-way and making the stomach smaller.
