Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a cassette loading device for a tape recorder, and more particularly to a cassette loading device for inserting and loading a tape cassette onto a cassette holder from the front thereof.

(Summary of the Invention) The present invention provides a cassette loading device in which a cassette holder is moved horizontally from an unloading position and then vertically to convey a tape cassette to a loading position.
The cassette holder is provided with a spring member which is located at a position retracted from the pressing position when the cassette holder is in the ejecting position and moves to the pressing position at the beginning of horizontal movement of the cassette holder from the ejecting position;
By positioning the tape cassette by pressing the tape cassette onto the bottom plate of the cassette holder using this spring material, operations when inserting the tape cassette onto the cassette holder at the ejection position or removing it from the holder are possible. It has a heightened sense of sexuality.

(Prior Art) Conventionally, in this type of cassette loading device,
When the tape cassette is inserted and placed on the cassette holder, the hook is elastically engaged with a concave loading grip on the top surface of the tape cassette to position the tape cassette.

(Problems to be Solved by the Invention) However, in the above-mentioned conventional configuration, when the tape cassette is inserted onto the cassette holder or taken out from the cassette holder, the resistance caused by the engagement and disengagement between the loading grip and the hook is reduced. This resulted in poor operability.

(Means for Solving the Problems) In order to solve the above problems, the present invention inserts and places a tape cassette on a cassette holder from the front, moves the cassette holder from the horizontal direction to the vertical direction, and then inserts the tape cassette into the cassette holder. A cassette loading device for transporting tape cassettes from a take-out position to a loading position includes a spring member attached to a spring support portion of the cassette holder to press the tape cassette onto the bottom plate of the cassette holder, and a spring member provided on the cassette holder to press the tape cassette onto the bottom plate of the cassette holder. a pressure release member for retracting the material from the pressure position, and a pressure release member that holds the spring material at a position retreated from the pressure position when the cassette holder is at the ejection position, and the spring material is held in a horizontal direction from the ejection position of the cassette holder. and a release member operating means for operating the pressure release member to move the spring member to the pressure position at the initial stage of movement.

(Function) In the above configuration, when the cassette holder is in the ejection position, the spring material is in a position retracted from the pressing position, so that there is no resistance from the spring material when the tape cassette is inserted into or removed from the cassette holder. When the cassette holder moves horizontally from the take-out position, the spring material moves to the pressing position at the beginning and presses the tape cassette onto the bottom plate of the cassette holder, which may cause the tape cassette to shift during transportation. disappears.

Therefore, there is no need to employ the concave-convex engagement between the loading grip and the hook as in the prior art, and the operability when loading and unloading the tape cassette is improved.

Next, the loading device for the tape cassette 1 is
This will be explained according to FIGS. 3 to 3.

The cassette holder 6 includes a bottom plate portion 6a, both side plate portions 6b, and a spring support portion 6 extending inward from the upper side of the both side plate portions 6b.
A plate spring (spring material) is attached to the plate surface of this spring support portion 6c, and a square hole 6d is bored therein. The plate spring 7 has one end as a fixed end, and the other free end as a square hole 6dl.
The spring support part 6c is provided with a reed extending downwardly (a state in which the tape cassette 1 is pressed onto the bottom plate part 6a of the cassette holder 6), and a contact piece 7a protruding outside the side plate part 6b at the intermediate part. have

The slider receiver plate 8 is slidably supported on the bottom plate 6a of the cassette holder 6 by fitting a bent piece 8a at the center of the front edge into a structure 6e of the bottom plate 6a of the cassette holder 6. The plate 8 of the slider receiver has a bent piece 8b that passes through the notch 2a of the tape cassette 1 at the rear edge and hits the contact piece 3b, and a bent piece 8c that hits the stopper of the frame described later on both sides of the rear end. Further, a protrusion 8d is formed on the plate to fit into the groove 3a of the tape cassette 1, push in the lock pin 5, and release the lock of the slider 3 by the pin 5a.

The auxiliary lever 9 has arms 9a at both ends, and this arm 9
The free end portion of a is rotatably supported on the outer surface of both side plate portions 6b of the cassette holder 6 by means of a guide shaft 10, so that the cassette holder 6 is provided across the upper side of the cassette holder 6.

This auxiliary lever 9 has a positioning piece 9b bent at its rear edge, and this positioning piece 9b protrudes below the spring support part 6c of the cassette holder 6 behind the spring support part 6c.

The cassette holder has an angle (pressure release member) 11 with the free ends of the arms lla on both sides positioned between the side plate parts 6b of the cassette holder 6 and the arm 9a of the auxiliary lever 9, and is connected to the guide shaft 10 common to the arm 9a. It is pivoted so that it can move up and down. The angle 11 of this cassette holder is located at the front of the lower part of the cassette holder 6, and a protrusion 11b that engages with the data hole 5 of the tape cassette 1 when rotated upward.
The structure has a structure in which the arm 11a is rotated downward.
By pushing up the contact piece 7a with the free end of the plate spring 7 and bending the free end of the plate spring 7 upward, the plate spring 7 is moved back from the pressing position of the tape cassette l.

Next, a support mechanism for the cassette holder 6 will be explained. The frame 12 is located inside the tape recorder body,
First and second guide grooves 13 and 13a of the same shape, each consisting of a horizontal groove extending in the horizontal direction and a vertical groove extending downward and continuous with the rear end of the horizontal groove, are formed in the side plates 12a spaced apart from each other in the front and rear. ing. The cassette holder 6 can be moved to the take-out position (front) by inserting the guide shaft 10 into the first guide rJ#13 and the guide shafts 14 at the rear ends of both side plates into the second guide grooves 13a. It is supported by the frame 12 so that it can move backward in the horizontal direction from the position) and then move downward in the vertical direction. As described above, the support mechanism of the cassette holder 6 includes the guide shaft 10.14 and the guide groove 13 of the frame 12.
, 13a.

Further, the side plates 12a of the frame 12 are provided with a third guide groove 13b consisting of a horizontal groove extending in the horizontal direction, a vertical groove continuing to the rear end of the horizontal groove and extending downward, and an inclined groove continuing to the front end of the horizontal groove and extending diagonally downward. A guide shaft 15 provided on the arm Ila of the angle 11 of the cassette holder is inserted into this guide groove 13b. In the guide *13b, the inclined groove acts on the guide shaft 15 at the beginning of the backward movement of the cassette holder 6 in the horizontal direction from the take-out position, and the cassette holder rotates the angle 11 upward, and the cassette holder 6 During the later stages of horizontal backward movement and downward movement from the take-out position, the horizontal and vertical grooves act on the guide shaft 15, and the cassette holder moves the angle 11 integrally with the cassette holder 6. The cassette receiver constitutes an angle 11, that is, a release member operating element that rotates the elastic pressure release member upward by the inclined groove portion and the guide shaft 15.

Next, the lift-opening mechanism of the tape cassette 1 will be explained. This lift release mechanism is composed of a beam lever 16, a spring 17, a cassette holder 6, etc., and the lift lever 16 is attached to a bent piece 12b of the frame 12.
is supported by a shaft 18 so as to be vertically movable, and the lit lever 16 is always biased and held at a predetermined position by a spring 17. The lit lever 16 is formed with a protrusion 16a against which the inclined edge 6f formed at the rear end of the side plate portion 6b comes into contact when the cassette holder 6 moves backward. Rotational force is applied via the protrusion 16a by the action of the inclined edge 6f, which rotates against the spring 17 and engages with the lower end of the slit 2 of the tape cassette 1 that descends together with the cassette holder 6, opening the slit 2. It is something that makes it work.

The opening/closing door 19 opens and closes the cassette insertion slot of the tape recorder main body, and the cassette holder 6 is linked to this opening/closing operation via a holder moving mechanism. This holder moving mechanism consists of a fan-shaped door gear 20 attached to the door arm 19a of the opening/closing door 19, an intermediate gear 21. It is composed of an arm gear 22, an overstroke arm 23, a compression spring 24, etc., and the overstroke arm 23 has one end rotatably connected to the guide shaft 10, and the other end is loosely fitted into a long hole 23af in the pin part 22a of the arm gear 22. In addition, a compression spring 24 is interposed between the pin portion 22a of the arm gear 22 and the guide shaft 10. The opening/closing door 19 is always urged in the opening direction by a spring 25.

In FIG. 1, reference numeral 12c is formed vertically by cutting and bending the inner surfaces of both side plates 12a of the frame 12, and the slider receiver prevents the plate 8 from moving backward when it comes into contact with the bent piece 8c of the plate 8. The regulating stopper 12d is also formed on the inner surface of the both side plates 12a, and is a projection that pushes up the rear end side of the auxiliary lever 9 when the cassette holder 6 moves backward and then moves downward.

26 is another guide shaft provided on both side plates 6b of the cassette holder 6, and 27 is a guide shaft provided on the rear end of the arm lla of the angle 11 as the cassette holder. Also, the cassette holder 6 and the cassette receiver are used to move the angle 11 more stably.

Reference numeral 28 denotes a guide plate made of a resin molded product attached to the inner surface of both side plates 12a of the frame 12, and is used to guide the cassette holder 6 in the horizontal direction from the ejecting position, in the later stages of retraction, and in the later stages of the retraction movement of the cassette holder 6.
Grooves 28a and 28b are formed into which the guide shafts 26 and 27 fit during the downward movement of the slider, thereby stabilizing the movement during this period. The reason why the guide grooves of the guide shafts 26 and 27 are not formed in the frame 12 and is formed using a guide plate 28 separate from the frame 12 is that
There are already three guide grooves 13, 13a, 1 on the side plate 12a of 2.
3b is formed and two more guide grooves are formed.
This is because the strength of the frame 12 cannot be maintained sufficiently.

28c is formed on the guide plate 28 so as to face the front surface of the upper end of the stopper 12c, and the slider receiver is a stopper that restricts the forward movement of the plate 8 by contacting with the bent piece 8c.

In the above configuration, when the opening/closing door 19 is opened, each guide shaft 10.14.15 is at the front end position of each guide groove 13.13a, 13b as shown in FIG. 2(a), and the cassette holder 6 is removed. placed in position.

In this ejecting position, the angle 11 of the cassette receiver is in the downward rotating position as shown in FIG. 7 is bent upward. On the other hand, the forward movement of the slider receiver plate 8 is restricted by the bending piece 8c coming into contact with the stopper 28c, and the slider receiver is located at the most rearward position with respect to the bottom plate portion 6a of the cassette holder 6.

In this state, the tape cassette 1 is inserted and placed on the bottom plate portion 6a of the cassette holder 6 through the cassette insertion opening of the tape recorder main body. At this time, tape cassette 1 is
The cassette holder can be inserted smoothly without the protrusion 11b on the angle ll getting in the way and without being subjected to resistance from the leaf spring 7. The tape cassette 1 is inserted until its slit 2 touches the positioning piece 9b of the auxiliary lever 9, and the tape cassette 1 is positioned on the bottom plate 6a of the cassette holder 6.

After the tape cassette 1 is inserted, when the opening/closing door 19 is closed, the tape cassette 1 is transported from the removal position to the installation position by the following operation.

When the opening/closing door 19 starts to close, the door gear 2
0, the arm gear 22 starts rotating via the intermediate gear 21,
The guide shaft 10 is moved rearward within the lateral groove of the guide groove 13 via the overstroke arm 23. That is, in the cassette holder 6, the guide shaft 10.14 is aligned with the guide groove 13,
The cassette holder 6 moves along with the cassette holder 6 at the angle 11 and the guide shaft 15 at the beginning of the horizontal backward movement of the cassette holder 6 from the ejecting position guided by the horizontal groove 13a. As it moves along the inclined groove of the guide groove 13b, it gradually rotates upward, and when the guide shaft 15 reaches the horizontal groove of the guide groove 13b, the protrusion 11b engages with the data hole la of the tape cassette 1. do. On the other hand, the leaf spring 7 gradually lowers the cassette holder as the angle 11 rotates, and when the guide shaft 15 reaches the lateral groove of the guide groove 13b, the tape cassette 1''f bottom plate portion 6a of the cassette holder 6 Therefore, the tape cassette 1 is reliably positioned and fixed on the bottom plate portion 6a of the cassette holder 6.

After the guide shaft 15 reaches the lateral groove of the guide groove 13b, the cassette holder and the angle 11 move integrally with the cassette holder 6.

Further, during the backward movement of the cassette holder 6, the bent piece 8C of the slider holder plate 8 comes into contact with the stopper 12c to prevent the backward movement, and the slider holder is in a state of receiving the cassette holder 6 which is moving backward thereafter. Then, in the slider holder, the protrusion 8d of the plate 8 fits into the groove 3a of the tape cassette 1 that is retreating together with the cassette holder 6, and pushes the lock pin 5, and the bent piece 8b is inserted into the slider 3.
As a result, the slider 3 of the tape cassette 1 is moved from the position shown in FIG. 4(a) to the position shown in FIG. 4(b). It will be in a backward state.

When each guide shaft 10, 14.15 reaches the rear end (vertical groove upper end) of each guide groove 13, 13a, 13b as shown in FIG. The slider 3 of the tape cassette 1 is placed on the bottom plate 6a of the cassette holder 6 in the largest overlapped state as shown in FIG.
), these states are maintained by the vertically long stopper 12c during the subsequent lowering operation. Further, the inclined edge 6f of the side plate 6b of the cassette holder 6 is in contact with the protrusion 16a of the lit lever 16, as shown in FIG. Located in

When the closing operation of the opening/closing door 19 further progresses from the above state, each guide shaft 10, 14.15 moves into each guide groove 13,
In addition to the longitudinal grooves of 13a and 13b, the strong guide shafts 26 and 27 of the auxiliary elements are also located in the grooves 28a of the guide plate 28.

28b, the cassette holder 6, the slider holder plate 8, and the cassette holder angle 11 begin to move downward integrally and in a stable state. During this downward movement, the rear end of the auxiliary lever 9 is pushed up by the protrusion 12d, so that the auxiliary lever 9 rotates about the guide shaft 10 as a fulcrum.
The positioning piece 9b is moved away from the slit 2 of the tape cassette 1, allowing the slit 2 to open. On the other hand, the lift lever 16 is applied with a rotational force by the inclined edge 6f of the cassette holder 6 via the protrusion 16a, and rotates against the spring 17 in the direction of the arrow shown in FIG. 3(a). Tape cassette 1 descends with
The tip of the tape cassette 2 is hooked onto the lower end of the slit 2, and the slit 2 is opened as shown in FIG. 3(b) by synergistic action with the lowering of the tape cassette 2.

When the opening/closing Ji 19 completely closes the cassette insertion slot of the tape recorder main body, each guide shaft 10°14.15
As shown in FIG. 2(c), each guide groove 13° 13a,
When the tape cassette 1 reaches the lower end of the vertical groove 13b, the tape cassette 1 and the cassette holder 6 reach the mounting position. In this state,
The slit 2 of the tape cassette 1 is completely opened as shown in FIG. 4(c).

As described above, the cassette holder 6 moves backward in the horizontal direction from the take-out position as the opening/closing door 19 closes, and then moves downward to transport the tape cassette 1 to the mounting position.

Next, when removing the tape cassette 1, the door 19 is unlocked by operating an eject button, for example.

Then, the opening/closing door 19 performs an opening operation due to the biasing force of the spring 25, and with this opening operation, the arm gear 22 rotates in the opposite direction to the previous one, and the cassette is opened by the opposite direction to the previous one. The holder 6 is moved upward and then moved forward to transport the tape cassette 1 to the take-out position.

When the tape cassette 1 has reached the take-out position, the projection 11b of the angle 11 does not interfere with the cassette holder, and the tape cassette 1 can be taken out from above the cassette holder 6 without being subjected to resistance from the leaf spring 7.

In the above embodiment, a recess may be provided on the upper surface of the tape cassette 1 so that the plate spring 7 engages with the recess when the leaf spring 7 moves to the pressing position. In this way, the protrusion 11b of the angle 11 can be omitted from the cassette holder. Of course, when the cassette holder 6 is at the take-out position, the leaf spring 7 is at a position retreating from the pressing position of the tape cassette 1, and when the tape cassette 1 is taken in and out, it is not affected by the recess on the upper surface and the leaf spring.

In addition, the present invention is not limited to the embodiments described above and shown in the drawings, and it goes without saying that the present invention can be implemented with appropriate modifications within the scope of the gist. , a cassette loading device that inserts a tape cassette onto a cassette holder from the front and moves the cassette holder from a horizontal direction to a vertical direction to transport the tape cassette from an ejection position to a loading position. By moving the spring material to the pressing position and pressing the tape cassette onto the bottom plate of the cassette holder at the beginning of horizontal movement, it is possible to prevent the tape cassette from shifting during transportation. There is no resistance to the tape cassette being taken in and taken out at the take-out position, and the operability in putting in and taking out the tape cassette can be improved.
