Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cassette player of the type in which when a cassette is inserted horizontally, the cassette moves vertically and is automatically set to a playing state.

In this type of player, when the cassette is set in the playing state, it is desirable that the head, pinch rollers, etc. also automatically move toward the cassette to enter the playing state.

However, in some cases, the head and pinch roller may move before the cassette is set in the playing position, causing a problem with the setting of the cassette, and this must be taken into consideration.

The present invention allows the movement timing of the cassette head, pinch roller, etc. to be easily obtained, and will be described below with reference to embodiments shown in the drawings. FIGS. 1 to 6 show the front, top, right side, left side, back surface, and rear surface of the player as a whole. Here, 1 is a guide holder with tape guides 3 of a cassette 2 attached on both sides, 4 is a cassette holder that rotatably holds the protrusion 5 of the tape guide 3 at its tip and has a protrusion 6, and 7 is a cassette holder. The holding plate rotatably holds one side of the main chassis 9 and is perpendicular to the main chassis 9.

8 is an auxiliary plate rotatably attached to the holding plate 7 at one end and the guide holder 1 at the other end, 9 is the main chassis, and 10 is a side plate attached to one side of the main chassis 9.
Timing stopper 11 and sliding plate stopper 12 on the side
It has protrusions 13 and 14 for holding the parts, and elongated holes 15 to 18.

Reference numeral 19 denotes a long hole 2 which is movable in the horizontal direction with respect to the main chassis 9 and corresponds to the protrusion 21 provided on the charge 27.
0 and a protrusion 22 protruding from the elongated hole 16, and is pulled forward by a sliding spring 23.

24 is below the sliding plate 19 and has a hop-up spring 25
The sliding plate 19 is a second sliding plate that is similarly pulled in the front direction by the guide shaft 41 corresponding to the closest hole 17, etc.
Similarly, it is movable in the horizontal direction with respect to the main chassis 9.

One end of the charge plate 27 is rotatably held on the inside of the guide holder 1 and the holding plate 7 with respect to the holding plate 7, and the end of the charge plate is rotatable on the inside of the side plate 10.

28 is an eject plate whose base is rotatably held by the main chassis 9, and an eject spring 29 is placed between it and the sliding plate 19.
On the other hand, an engaging portion 32 and a lock release piece 33 corresponding to the stopper piece 31 of the stopper 30 are provided.

34 is a sliding plate stopper spring that presses the sliding plate stopper 12 clockwise; 35 is rotatably held by the sliding plate 19, and is pressed clockwise by a hook spring 36 applied to the same plate 19; A protrusion 37 provided on the sliding board 24 of
A hook plate having a protrusion 39 corresponding to an engaging portion 38 and a release piece 33 that engage with
This is a cassette holder spring whose end is applied to the cassette holder 4. FIG. 7 shows the components on the side plate 10 side. 8 to 10 show the process of inserting the cassette 2 from the state shown in FIG. 4 and setting the cassette 2 to a playing state. First, when the cassette 2 is inserted along the tape guide 3 from the state shown in FIG. 4, the floating plate 19 is moved through the charging plate 27 in the process shown in FIGS. 8 and 9. During the movement process of the sliding plate 19, the protrusion 22 provided on the sliding plate 19 corresponds to the stopper 12 as shown in FIG. Engage as shown in FIG.

Note that 41 is a movement restriction of the guide shaft stopper 2 provided on the second sliding plate. Further, a hook plate 35 provided on the sliding plate 19 is pressurized so as to engage with the second sliding plate 24, and is engaged when the sliding plate 19 moves to a certain point from the state shown in FIG. The portion 38 also engages with the protrusion 37, and the sliding plate 19
The second sliding plate 24 will also follow the subsequent movement of. As a result, as the second sliding plate 24 moves, the guide shaft 41 also moves within the elongated hole 17 as shown in FIGS. This will loosen the engagement with the portion 22.

Therefore, since the protrusion 22 engages with the stopper 12, the cassette 2 is locked in the state shown in FIG.

At this time, in order to hold the stopper 12 on the side plate 10, as shown in FIG. 22 in a certain amount (required amount) to cassette 2
It will be moved in the direction of insertion.

Since the stopper 12 also moves as the sliding plate 19 moves, the timing stopper 11 is rotated in the direction of arrow 42 at one end of the sliding plate stopper 12.

[The stopper 11 is pressurized by a spring 43 in a direction opposite to the arrow 42. ] Accordingly, the cassette holder 4 rotates as shown in FIG. 4 in order to disengage the protrusion 44 provided at one end of the cassette holder 4 that had been engaged with the groove 1 of the timing stopper 11, and the cassette 2 is rotated as shown in FIG. It will be moved vertically to correspond to the drive system on the main chassis 9. In other words, after inserting the cassette 2 a certain distance in the horizontal direction,
Timing stopper 1, which corresponds to cassette vertical movement means, uses a part of the force that tries to return when the insertion is stopped to use a cassette locking means represented by stopper 12.
1 to unlock the cassette holder 4 and rotate it so that the cassette 2 can be set. Therefore, there is no possibility of fingers being caught during the process of inserting or inserting the cassette 2, and when the fingers are removed from the cassette 2, the cassette 2 moves in the vertical direction, so there is no need to consider the pressure exerted by the fingers.

In ejecting, the stopper 30 is rotated to disengage the eject plate 28, and the plate 28 is rotated toward the back of the player by the action of the eject spring 29.

Accordingly, the second sliding plate 24 is unlocked by the release piece 33 of the same plate 28 to rotate the hook plate 35, and the second sliding plate 24 is restored.

When the sliding plate 24 is restored, the sliding plate stopper 12 is rotated by the guide shaft 41 so as to disengage the protrusion 22, so that the state shown in FIG. 10 returns to the state shown in FIG. 4. Furthermore, since the charge plate 27 also returns, the cassette 2 will fly out from the tape guide 3 due to the return force at that time. The above has explained the relationship between setting and ejecting the cassette at the playing position, but with reference to Figs. 11 and 12, the timing of setting the cassette at the playing position,
The relationship between the pinch rollers will be explained.

51 is movably supported with respect to the main chassis 9,
It is a cassette detection piece that is pulled forward by a spring and has a joint surface 52 to the charging plate 27 and a stopper part 53.

A head mounting plate 54 is movable in the same direction as the cassette detection piece 51 with respect to the main chassis 9, and holds the head 55 via an angle adjustment plate 56, while a lever 57 is engaged during fast forwarding and rewinding. It has a mating groove 58 and a recess groove 59 for the pinter roller mounting shaft 60 provided on the main chassis 9.

61 is a pinter roller 62 provided on the head mounting plate 54
64 is a holding shaft of a spring 63 that pulls the crimping and head mounting plate 54 toward the front, and 64 is a lock spring 6 attached to the rear surface of the main chassis 9.
5, a cassette movement detection piece 67 having an engaging part 66 that engages with the stopper part 53 of the cassette detection piece 51 protrudes from the hole 69 of the main chassis 9, and is attached to the hole (not shown) of the head mounting plate 54. ) is a hole through which the cassette movement detection piece 67 of the head attachment plate stopper 64 projects upward.

With this configuration, when the cassette 2 is in the state shown in FIG. 4 (that is, when the cassette 2 is not set in the playing state as shown in FIG. A cassette movement detection piece 67 and a stopper piece 68 are made to protrude upward.

As a result, the engaging portion 66 engages with the cassette detection piece 51 that is pulled forward by the spring as shown in FIG.
The cassette movement detection piece 67 does not move unnecessarily below the closing chassis 9. In this state, the stopper piece 68 of the head mounting stopper 64 is attached to the head mounting plate 54.
By engaging with a hole (not shown) provided in the head mounting plate 54, the head mounting plate 54 will not move unnecessarily toward the front. When the cassette 2 is inserted, the charging plate 27 also moves, so that the cassette detection piece 51 is moved in the direction of the arrow in FIG. 11 by the charging plate 27.

Accordingly, the engagement between 66 and 53 is released. When the cassette 2 is inserted and locked to the state shown in Fig. 9, and then moved as shown in Fig. 10 by the method explained earlier,
By pressing the unlocked cassette movement detection piece 67 of the cassette 2 in the direction of the main chassis 9, the stopper piece 68 will also move in the direction of the main chassis 9, and the head support plate 54 will be moved. The lock is released, so that the mounting plate 54 moves toward the cassette 2 set in the playing state, and becomes in the playing state.

In this case, the spring 63 functions as a spring for moving the head mounting plate 54 and as a force for pressing the pinter loaf 62 in the playback state. In the playback state, use the lever 57 to close the head mounting plate 54.
By pressing in the direction of the arrow, the pin roller 62 is released from the capstan 71, and fast forwarding and rewinding are performed.

On the other hand, during ejection in the playback state, the head mounting plate 54 is forcibly restored via the holding shaft 61 as the eject plate 28 moves when it is displaced from the stopper piece 31.

This allows the cassette 2 to move from the state shown in FIG. 10 to the state shown in FIG. As a result, the head mounting plate 54 is locked. According to the present invention, as the cassette is moved in the horizontal direction, the cassette detection piece and the cassette movement detection piece are disengaged (first unlocking), and as the cassette is next moved vertically, This is to disengage the stopper piece from the head mounting plate (secondary unlocking), and since the head mounting plate can only be moved by double unlocking, the regular process is not complete. It is possible to prevent malfunctions such as movement of the head mounting plate before the time elapses.
