Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application This invention relates to a mounting device for manually mounting a cassette (cassette tape) onto a tape recorder.

(B) Conventional technology In this type of conventional mounting device, a door is pivotally attached to the surface of the tape recorder cabinet, a cassette holder is provided on the back side of the door, and after the cassette is manually inserted into the cassette holder, the door is opened. By closing the cassette, the cassette is loaded into the tape recorder.

(c) Problems to be solved by the invention However, in such a conventional mounting device,
Since there is almost no space between the door and the cassette, and the entire cassette is hidden behind the door, there is a problem in that it is particularly difficult to remove the cassette.

The present invention has been made in consideration of these circumstances, and it is an object of the present invention to provide a compact cassette mounting device in which the cassette can be easily attached and detached.

(d) Means for Solving the Problems This invention provides a cassette mounting device for a tape recorder in which a cassette is lowered into the cabinet through an opening provided on the top surface of the cabinet and mounted therein, which has an opening at the front for inserting the cassette. , a box-shaped holder provided with a locking piece at the rear for locking the cassette, and holding the inserted cassette so that it can be removed from the opening with the rear end of the cassette remaining; Lifting means for supporting the surface and lifting the holder to expose it from the cabinet surface and lowering the holder to house it in the cabinet; urging means for urging the lifting means in the upward direction; A protrusion that is pressed when the holder is lowered into the cabinet, and a protrusion that is provided on the top surface of the holder so that it can slide in the direction of inserting and removing the cassette from the holder. A plate-shaped lid that can move to cover the upper surface of the rear end of the cassette and close the cabinet opening, and the lid slides in the direction of inserting and removing the cassette relative to the holder in conjunction with the raising and lowering movements of the lifting means. This cassette loading device for a tape recorder is characterized by comprising an interlocking means for moving the holder into the cabinet, and a locking means for removably locking the holder to the lifting means to stop the lifting operation when the holder is lowered into the cabinet. .

(E) When the cassette is mounted, the cassette is inserted through the opening of the holder until it is locked by the locking piece, and the rear end of the cassette is held in the holder with the rear end exposed from the opening. When the protrusion is pressed, the elevating means is lowered and the holder is housed in the cabinet, and the interlocking means causes the lid to slide on the upper part of the holder in the direction of removing the cassette, covering the upper rear end of the cassette, and the holder is removed. It is installed in the cabinet, the lifting means is locked with the locking means, and the lid closes the cabinet opening.

When the cassette is taken out, when the locking means is disengaged from the lifting means, the lifting means lifts the holder out of the cabinet due to the biasing force of the urging means.

At the same time, the lid moves the top surface of the holder relative to the holder in the cassette insertion direction by the interlocking means, exposing the rear end of the cassette from the holder opening. Therefore, since the rear end of the cassette is exposed, the cassette can be inserted or removed by supporting the rear end with fingers, making both operations easy. Moreover, since the lid closes the cabinet opening when the cassette is installed in the cabinet, the appearance after installation is excellent.

(f) Examples Hereinafter, the present invention will be described in detail based on examples shown in the drawings. This invention is not limited by this.

First, the structure of the cassette tape used here is the same as that of a general cassette that accommodates conventional magnetic tape, so it is not specified in particular. Therefore, in the following description, details such as the capacity and shape of the cassette will be omitted, and the discussion will be based on the assumption that the cassette has a simple box shape.

First, mechanically speaking, the cassette loading device according to the present invention can be roughly divided into an insertion/removal mechanism (elevating means) for loading and unloading the cassette tape into and out of the tape recorder body, and a device inside the insertion/removal mechanism for loading and unloading the cassette tape under certain conditions. There are three main parts: a holding mechanism (holder) that is supported by a holder, and an exterior lid that is located within the insertion/removal mechanism and whose relative position can be moved as necessary. Note that in order to actually play back a cassette using a drive device in a tape recorder, in addition to the above-mentioned mechanism, a restraining mechanism for suppressing the cassette tape with a constant pressure is required. Since they are not directly required, they are not described in the examples.

As shown in FIG. 1, the insertion/removal R mechanism (elevating means) has left and right side plates 2 and 3 that are bases for supporting each mechanism, and are joined to the main body of the tape recorder by fastening parts (not shown). ing.

Inner bent portions 1 provided on the left and right sides of the front surface of this cassette holder 1. ．． 1 serves as a contact for regulating the insertion position of the cassette tape when the cassette tape is inserted into the cassette holder. As mentioned above, in order to actually play back a cassette using a drive device in a tape recorder, etc., in addition to the cassette holder 1, a restraining mechanism for suppressing the cassette tape with a constant pressure is required. In the case of a cassette holder shaped like the one shown in FIG. 1 of this embodiment, a temporary spring or the like is installed on the upper plate portion of the cassette holder, and the cassette tape inserted into the holder is constantly pressed against the bottom plate of the holder, that is, the tape. Means for suppressing the noise toward the recorder body side is often used. Although a direct explanation of this suppression mechanism will be omitted hereinafter, it is assumed that it exists and functions in a state not shown.

Next, the exterior lid will be explained. First, the fulcrum pin 18 installed on the upper plate surface of the cassette holder ■ mentioned above is the fulcrum hole of the rotary lever 10! 0. The rotary lever lO is rotatably inserted into the cassette holder, and the rotary lever lO is always biased in the clockwise direction by a spring 12 hung between the hole 104 and the bottles 1, 1 on the cassette holder. In addition, the square hole 10s of the rotary lever 10 has a bin 1 on the slide lever 11, which will be described later.
1 degree is inserted, the biasing force of the spring 12 is transmitted as a return force of the slide lever 11 in the direction of arrow A. In other words, the slide lever 11 slides as the rotary lever lO rotates.

On the other hand, a projection lO2 is provided at one end of the rotating lever 10, and the end! O, protrusion of U-shaped arm 5 5. contact during operation.

Note that the slide lever It has a guide groove 11. as a guide for its sliding operation. , l 1. , I1° are drilled into them, and guide pins it, Is, and ls on the cassette holder are respectively inserted and retained therein. Mounting holes IIs' and I provided on the top surface of the slide plate 11

As a result, the outer Ti cover 13 is moved together with the slide lever 11 by some rotational movement of the rotary lever IO.
It becomes possible to slide on the top surface of.

Holder on the other hand! As will be described later, the protrusion 1+o fitted on the top allows the cassette tape to be inserted into the holder ■ when the cassette tape is attached or detached, that is, when the cassette tape is inserted into the holder ■ from the tape recorder main body, a series of insertion and removal mechanisms including the cassette holder 1 are open. It is provided as a part on which the fingers of the hand or the like should be placed in order to press the holder l when the tape recorder is housed in the tape recorder main body.

Next, the operation of the above configuration will be explained. First, when loading a cassette tape, the eject state of the tape recorder main body, that is, the standby state of the insertion/removal mechanism parts including the cassette holder 1 before loading the cassette will be described. In FIG. 2, the guide arm 6 has its spring hooked portion 6. and the spring hook on the side plate 2 is part 2. The pin 61 is moved into the deformation guide groove 2. on the side plate 2 by the restoring force of the spring 9 applied between the pin 61 and the deformation guide groove 2. The groove moves in the direction of the arrow, and stops when it comes into contact with the end of the groove. And pin 61,
Fulcrum/hole 6. and the fulcrum shaft 5. The three points are in a positional relationship that constitute the vertices of a triangle.

Also, the position of the fulcrum pin 14 rotatably connected to the hole 64 at the other end of the guide arm 6, and the guide groove 5 on the U-shaped comb 5. The two guide pins 13 on the cassette holder (2), which are slidably inserted into the cassette holder (2), are also arranged in the same manner as described above. In other words, the cassette holder 1 is kept inclined with respect to the cabinet surface 14 of the tape recorder main body by an angle α in FIG. 2, making it easy to insert the cassette tape I5 into the cassette holder 1.

The related explanation of the exterior M13 in this state is given in Section 4-(1).
Referring to the drawings, first, the protrusion 5. The end 54 is a cassette holder! The end 10 of the protrusion tO,' of the rotating lever 10 on top
．． , the rotary lever IO is located at a position separated by a gap a from
Press the bottle II supplied to No. 6 in the direction of arrow A. Therefore, the slide lever 14 and the exterior lid 13 integrally attached thereto are both in the position shown in FIG. 4-(1), that is,
Guide pin 17 on cassette holder 1 and guide on slide lever 11, 741! are placed in a state where one end of the two is in contact with each other and stopped. Also, in the state shown in Figure 4-(1), the outer tank lid! 3 is a cassette holder! Upper protrusion 11
In addition to being in a positional relationship that is dimensionally shifted from 0, it is also a cassette tape! 5 is in a state where the shaded part is exposed, so that when taking out the cassette tape 15, it can be easily placed with a finger or the like.

FIG. 5-(1) is a perspective view of the eject state shown in FIGS. 2 and 4-(1) as viewed from the outside of the tape recorder main body. When the above is in the ejected state and the cassette tape is inserted into the cassette holder 1 from this state, the front edge surface of the cassette tape is inserted into the inner bent portions 1.12 provided on the front left and right sides of the cassette holder l shown in FIG. The position of the holder 1 is restricted within the holder 1 by abutting against the holder 1 and the restraining mechanism within the holder 1. Next, in order to store the cassette tape in the tape recorder body, the protrusion on the cassette holder 1 shown in FIG. When the holder 1 is pressed in the direction of the arrow E, the holder 1 receives the pressing force and presses the hole 6 of the guide arm 6 through the fulcrum pin I4 on the side surface of the holder 1.
．． Since the guide arm 6 tries to push in the same direction, the guide arm 6 pushes the fulcrum hole 6. It tries to rotate counterclockwise around the center. At the same time, the guide pin l on one side of the cassette holder 1 is connected to the guide groove 5 on the U-shaped arm 5. The U-shaped arm 5 is attempted to be rotated clockwise around the fulcrum shaft 5° while applying a pressing force to the holder. Hole 6, which is a coaxial fulcrum. ,5. The arm 5 and guide arm 6 which are connected at , further expand the angle β formed by these arm portions from the state shown in FIG. In other words, the fulcrum bin!
4. Hole 6. ．． 5. Furthermore, each of the three connecting parts of the fulcrum shaft 55 rotates, and the guide bin 1 on the side of the arm holder 1. slides in the direction of arrow G within the guide Rs-, and the pin 61 deforms the guide groove 2. By sliding in the same direction as the arrow, the angle β will be enlarged from the state shown in FIG.

The force of the cassette holder 1 to escape from the tape recorder body is determined by the spring hook 6 on the guide arm 6.
and spring hooks on side plate 2. This is provided via the guide arm 6 by a spring 9 suspended between the handle and the handle, and serves as a repulsive force applied to the hand during the above-mentioned operation. When the protrusion of the cassette holder l is continued to be pressed, arm 5 and guide arm 6
The angle F formed by the holder l becomes larger, and the guide pin l on the side of the holder l moves further in the direction of the arrow G within the guide groove 5 of the arm 5, and the pin 61 on one guide arm 6 becomes It moves inside the deformation guide groove 2 of the side plate 2 in the same direction as the arrow, and further slides in the direction of the arrow 1 along the curve of the curve. In addition, the deformation guide groove 2 of this side plate 2
．． is inclined because the cassette holder l is inclined at an angle α with respect to the cabinet 14 of the tape recorder body during ejection as described above.

Regarding the other deformation guide groove 21, during the process from pressing the cassette holder ■ from the eject state to finally loading the cassette tape into the tape recorder body, the cassette holder and the cassette tape are It is formed to gradually correct the inclination angle from the angle α in the ejected state described above so that it becomes horizontal, that is, parallel to the top surface of the tape recorder body, and the cassette tape is completely stored in the tape recorder body. In this state, that is, in the state shown in FIG.
1h<located.

In addition, in FIG. 3, the lock pin l provided on the side surface of the cassette holder 1
After sliding on the top, lock part 4. It is in a locked state. Also, the spring hook 6 on the guide arm 6. Since the cassette holder 1 is always urged in the ejection direction by the spring 9 applied to the lock portion 4.
In contrast, lock bin 1 of cassette holder 1. is the third
In the figure, it is held in a pressed state in the direction of arrow C.

In addition to this locking portion, the pin 6 on the guide arm 6 is slightly regulated vertically within the width of the deformable guide groove 21 without causing a large deviation in its outer diameter. is reliably housed in a fixed position relative to the tape recorder body. Side plate 2 mentioned above
The upper lever 4 is always biased in the direction of the arrow in FIG. 3 by a spring (not shown), and when returning from the locked state shown in FIG. 3 to the ejected state shown in FIG. (not shown) moves the lever 4 in the direction of arrow B to release the locked state.

Next, a related explanation of the outer tank lid 13 in this state will be given.
The terminal protrusion 5 on the arm 5 in this case is the fourth -
(2) Take the position indicated by the solid line, which is moved in the direction of the arrow from the ejected position indicated by the imaginary line in the figure. The end 54 presses the end lO5 of the protrusion IO2 of the rotary lever IO in the direction of the arrow against the rotational force of the spring I2, and presses the rotary lever 10 counterclockwise. As a result, the square hole lO formed at the other end of the rotary lever 10
5 is the pin I1.5 on the slide lever 11. 4th - (1
) From the ejected state shown in the figure, move it in the direction of arrow B to the position shown in Figure 4-(2). Therefore, the positional relationship between the slide lever 11 and the outer cover +3 to which it is attached, the cassette holder l, and the cassette tape I5 should be adjusted so that the dimensions in the eject state shown in Figure 0 become zero. This is a mutually beneficial relationship.Therefore, the fourth-(
2) As shown in Figure 5-(2), the cassette holder 1 and its protrusion 1. . and the exterior MI3 are configured so that they overlap in an integral manner in appearance.

In this way, the cassette tape is loaded into the tape recorder main body, but the operation to take out the cassette tape from the tape recorder main body is as described above, by moving the lever 4 in the direction of arrow B in FIG. 3 by the external operation means. By avoiding the lock part 4. The pin l was in a locked state.

is released, and the spring hook 6 of the guide arm 6 is released. The restoring force of the spring 9 applied to the cassette tape is carried out by the reverse procedure of the cassette tape loading operation described above. And the second
Figure 4-(1) and Figure 5. Then, the eject completion state shown in FIG. 2, FIG. 4-(1) and FIG. 5-(1) is reproduced, and the cassette tape can be taken out from the cassette holder.

The insertion/removal VAM (elevating means) uses the pantograph type described above, but the
- (2) If explained with a diagram or designed so that the pressing means of the rotary lever in the tank lid sliding mechanism can be performed by an external means other than the U-shaped lever 5, a method other than the pantograph type described above can be used. It is possible to implement from

(G) Effects of the Invention Since the present invention is configured as described above, compared to conventional tape recorders in which the cassette holder and the lid are integrally fixed, the lid can be used to remove the cassette. By exposing the cassette from the lid by the amount that one's fingers can touch when ejecting the cassette, it is possible to improve the ease of inserting and removing the cassette. Can be shaped.
