Abstract

PURPOSE:To eliminate a loading exclusive motor to realize a compact structure of a cassette tape recorder, by giving reciprocating motion to a cassette pull- in/loading mechanism by means of the forward/reverse driving of a capstan driving motor. CONSTITUTION:A cassette 1 is automatically pulled in and loaded into a cassette holder 2 with an automatic ejecting operation through mechanical actions by means of a cassette pull-in/loading mechanism 33, the forward/reverse driving of a capstan motor 11 and a gear 47 fitted with a cam groove. The forward/ reverse revolution of the motor 11 is controlled by turning on and off a cassette detection switch 43, and at the same time both soft loading and ejection are possible just with the forward/reverse driving of the motor 11. For instance, if a detection switch 13 is turned on with insertion of a cassette, the motor 11 is revolved forward. Then either one of capstans 4 and 5 is revolved, and at the same time the gear 47 is driven to drive a pull-in action lever 35. Then a cassette pull-in member 25 is forcibly moved back by a pull-in lever 34. Thus the cassette 1 is pulled in automatically up to the prescribed position by an interlocking part 28 of the member 25.

Also, as shown in Fig. 13A, a sliding force is exerted in the direction '' on the arrow of the second sliding IUIIJ body (iHJ) by the tension spring (116)! In Fig. 168, the cassette holder (2) is raised and returned to the cassette insertion position of the tape cassette (1) in Fig. 2A, as described in M11. Ru.

Next, when the aforementioned cassette detection switch (43) is turned on, the motor [''υ] is driven to rotate forward in the direction of the arrow n in FIG. 10A, and the motor shaft (8 (j)
The first rotating body (1st rotor state) is driven to rotate in the direction of arrow 0 in FIG. 10A. The second rotary body (9υ) is rotationally driven in the direction of arrow q in FIG. 10A by the gear hook of the first rotary body (4) via the upper gear f9z.

However, at this time, the second rotating body 01) and the oscillating body I8! Due to the frictional effect caused by the interference between the rocker t8e and the rocker t8e, there is an intermediate till (centering on L9
In the figure, a rotational moment in the direction of arrow 0 acts, and the oscillating body and hot water are oscillated in the same direction.

Then, as shown in FIGS. 11B and 14B, the lower gear 4 of the second rotating body (91) meshes with the cam grooved gear (4η), and the lower gear 1 meshes with the partially toothed gear (7g).

The swing range in the 0 direction of the arrow is restricted.

When the cam grooved gear (41) is rotationally driven in the positive direction of the arrow, the engager (

A rotational force is applied to the retraction drive lever (c), and the retraction operation lever oe is held in the forward movement position shown in FIG. 110.

When the control member (101) is rotated in the direction of the arrow m in FIG. 14B, the other end (101b) of the control member (101) is moved to the second
It comes into contact with one end (110a) of the sliding body (110) and pushes it in the direction of the arrow. Then, one end of the tension spring (T16) is pulled in the direction of the arrow by the other end (110b) of the second sliding body (110), and the first sliding body (109 ) is slid in the direction of the arrow in FIGS. 138 and 140. As a result, the first sliding body (10

It is also possible to lock the cam grooved gear (4η) by bringing it into contact with the engager (4!1) or the cam grooved gear (-1η), which is far away in the radial direction from the center In this regard, it is preferable that the cam grooved gear (41) can be strongly locked.

Next, at the time of the above-mentioned ejection, the motor α1) is driven to reverse rotation in the direction of the arrow n' in FIG. 10B.

Then, due to the reverse operation at the time of loading as described in 011, the lower gear (G) of the second rotating body eυ is rotationally driven in the direction of the arrow q' in Figures 11D and 14D, and moves in the force direction M+ of the arrow θ'.

While rotating in the direction of arrow i in the figure or in the direction of arrow 1' in the 14th (2) figure, the engager (10!t) is rotated at the closed ends (100a) (100b) of the g ) and locks the cam grooved gear (μ?) at that position.
A locking device as an auxiliary device for locking η at a predetermined position is not required, and the structure can be simplified and costs can be reduced.

[tFf characteristics of the entire cassette retracting and mounting mechanism] According to the cassette retraction and mounting mechanism described above, the cassette holder (2

) cam mechanism enables slow mechanical movement and quiet operation. Therefore, no unpleasant popping sound is generated during loading or ejecting, and soft loading and soft ejecting are realized with a simple structure and a highly reliable structure.

In addition, as will be described later, the forward and reverse rotation of the motor (11) is controlled by turning on and off the cassette detection switch (4), and the soft loading and soft ejecting can be performed only by driving the motor αυ in the forward and reverse rotation. , Example tr
If it is a car stereo, soft loading and soft ejecting can be performed by remote control (operating a remote switch) from the rear seat.

In addition, it uses the cab stan drive motor 03) to perform CC rough loading and soft ejection, and does not use any special motors or electromagnetic devices, making it extremely limp.
This realizes a low-cost loading mechanism.

Then, it is applied as a set human power to the operation free lag flop circuit (FF5) which sets the forward rotation drive operation of the capstan drive motor Uυ by controlling the OR circuit (orti), and its Q output becomes the ``H# signal. The accessory power supply Acc+B, which is the other human power of the AND circuit (ANDI), is connected to the Q output of this operation flipping circuit (FF5) which becomes the ``H'' signal. , the signal is given to the motor control circuit (207) through the AND circuit (ANDI) as a signal for causing the motor (11) to rotate in the forward direction.

Then, the capstan drive motor 00 is driven to rotate in the forward direction, and as described above, the motor αυ is driven to rotate in the forward direction.
Normal and reverse playback, all tape running such as fast forwarding and rewinding in normal and reverse running states, and loading operations are performed. Therefore, by driving the motor aυ in forward rotation, the tape cassette (

This allows normal playback, back-scanning, tape forwarding or rewinding in a normal running state, or fast forwarding or rewinding tape running in a reverse running state.

Also, a part of the ``)■'' signal that is given as a set input from the OR circuit (oiti) to the operation flip-flop circuit (I''F5) of the motor (11) is connected to the diode (Dl).
It is applied as a reset input to the operation trigger flop circuit (FF4) of EJI80T, and its Q output is reset to become the @L' signal.

Note that this operation free lag flop circuit (FF4) includes a cassette detection switch (43) that is turned on when the tape cassette (1) is loaded and turned off when the tape cassette (1) is ejected. In this case, a reset input that becomes an @H'' signal is applied through the NOT circuit (NOT5) and the diode (D2), and the circuit is reset.

Therefore, the eject (EJgOT) CD'FF button switch (204) is suppressed.11. Then, as described above, the mutual reset operation by the mutual reset circuit (205) causes playback (PLAY), fast forward! 7 (FF) and unwinding R18W) each operating free lag flop circuit (F

Flip-flop circuit (FF5) is given as a reset input, and its Q output is reset to become an 'L' signal. Therefore, motor control 1 is applied through an AND circuit (ANDl).
A 9L" signal is applied to the path 111 (207), and the forward rotation part @J of the capstan drive motor aυ is stopped. Also, the 'H" signal of the operation free lag flop circuit (FF4) of the eject (EJ EOT) is applied. The Q output iJ,A becomes
When the @H' signal is given as the other input of the ND circuit (AND2) depending on the on state of the cassette detection switch (c), the motor (Iυ) is sent to the motor control circuit (207) through the AND circuit (AND2). It is given as a signal to drive the cab stan drive motor 0υ in reverse rotation.As a result,
The eject operation is performed as described above, and the tape cassette (1) is ejected.

As mentioned above, when the tape cassette t1) is not held in the cassette holder (2) and the cassette holding detection switch (20Ll) is turned on, a 6H'' signal is sent to the mutual reset circuit (205). An inhibit signal is given as an input to put the device in a non-operating state.

Therefore, it is possible to prevent the loading operation when the tape cassette <1) cannot be held in the cassette holder (2), making it easier to use, especially when performing remote control.

(Ill, one-cycle reverse control One-cycle reverse control 1. Basically, when the tape cassette (1) is inserted into the tape holder (2) and loaded, the tape is first rewound to the tape top and the normal After playing, if the end of the tape is reached, the tape is stored in the parser, and if it finally returns to the top of the tape, the tape cassette (1) is ejected using ft1ll tal.

For this control, one cycle reverse switch (209)

Next, with the one-cycle reverse switch (209) in the ON state, the tape cassette 1) in the ejected state is removed from the cassette holder (2) at the cassette insertion position of the tape cassette 1), and then the tape is re-entered. When the cassette (1) is inserted into the cassette holder (2) and loaded, etc., and when the tape cassette (1) that has been ejected is not removed from the cassette holder (2) and loaded again. We will explain the case where this is done.

Note that power is always supplied to the detection 7 flip-flop circuit (lI'F6) that stores the removal status of the tape cassette (1) from the sumo wrestler's holder (2), the designation flip-flop circuit (FF7) that specifies the tape running direction, etc. is being supplied.

When the normal set detection switch 0J is turned on, the NOT circuit (PLAY) of playback (PLAY) is activated through the N(J'l' circuit (N0T6) and the capacitor (C2)).

In addition, the flip-flop p1 path () specifies the tape running direction.
'F7) receives a trigger input from the system control circuit (206) through the OR circuit (012) when the tape end or tape top is detected from the playback and fast forward numbers. When this trigger input falls, the output and Q output force S are reversed, and the designation of the tape running direction can be reversed.

Therefore, in this case, when the rope ink force S1i is completed, the tape is rewound first, and if the tape top returns to normal, it is normal Yoshio. , If you return to the original position, you will be ejected.

Also, as a trigger input for the finger rectangular flip F+RA path (Fl"7) in the tape running direction, the 01'L circuit (O
It is also given by feeling the push button switch (208) of the direction (also DII) through the direction I). Note that as an input to the Oit circuit (012), a designated flip-flop circuit (L) is used in state I, when the tape cassette (1) is removed from the cassette holder (2) and the cassette retention detection switch (200) is in the on state.
In order to prevent the viewing output and viewing output of 'F7) from being reversed, an inhibit signal that becomes l) I'' signal is given. Therefore, by the suppression operation of the push button switch (208) of the direction (DI) Specifying the tape running direction tJs This is done when the cassette holding detection switch (200) is turned off.

In addition, the OR circuit (01 (5) is connected to the eject (■ Bow J
The operating flip-frog circuit (Fl"4) of the operating flip-frog circuit (FF4) is set, and part of the output that becomes the '1(" signal is given as a reset input. The setting drives the capstan drive motor aυ in reverse rotation, and the eject operation moves the cassette holder (2) back to the cassette insertion position of the tape cassette (1), thereby giving a reset input. Through the circuit C0IB), the system control circuit (206) detects the end of the tape or the tape end due to raw and fast forwarding (41), and controls the free lagging frog circuit (f) to specify the tape running direction.
A portion of the trigger force that becomes the 'f('' signal given to i'F7) is also given as a reset input.

With these, the detection frig 70 tube lO1 path (F'l
i'6) is reset so that its output is the 61J'' signal.

(Ji) In the latter case (when the tape cassette (1) is not removed from the cassette holder (2)), if the tape cassette (1) is not removed from the cassette holder (2), the cassette retention detection switch (20Ll) remains off. Therefore, the detection free-lag frog circuit (FF
6) is not given the set input that becomes the @H" signal, and the reset input of the L" signal is maintained at its output.

Therefore, the flip-flop circuit (1
'li'7) The IC remains in the state it was in when the tape cassette (1) was ejected without being set.

As a result, if the fiQ output is "H" (it), the system control circuit (206) is ejected by the "H" (Q output of g) or the Q output of the designated flip-flop circuit (FF7). A predetermined mode switching operation is performed depending on the reverse tape running direction, which is the same as when the tape is running.

Note that the Q output of the detection flip-flop circuit (FF6) is @

is set. As a result, the tape running force is 3 in the tape running direction when the loaded tape cassette (1) rJ1 tag is ejected without being rewound.
Therefore, in this case, this is a continuation of the case where the cheese 7° was ejected without being rewound, and if the time when it was ejected was when the tape was running during linux playback. A tape played by Barinos.

Running is started and reno (-) playback is performed. When the tape returns to the top, tJ: tape cassette (1) is ejected.

In addition, if the one-cycle reno switch (209) is in the OFF state, the It

However, since there is no ejection, the tape run of normal Imao and the tape run of reverse 6th raw are reciprocated.

The T circuit (NOT7) gradually emits light Sδ from the discharged capacitor (C6). Then, within a certain period of time until the terminal potential reaches a predetermined potential number due to the photoelectric field, the output terminal of the N07 circuit (N0T8) becomes 'H'.

Since l' signal is not given, eject (BJ H
The operational flip-flop circuit (li'F4) of UT) is not set and does not perform an eject operation. i.e. accessory power supply ACC+B by capacitor (C6)
This is due to the fact that the detection of the low potential (FO) is delayed. If the accessory power supply Acc+B recovers to the original potential, that is, @H' multiplied state within a certain period of time, the eject operation is performed because the terminal potential of the capacitor (C6) is discharged without reaching the predetermined potential. Never.

The eject operation caused by the Lee power supply Acc+8 being temporarily set to a low potential or 0■ is prevented.

Note that the accessory power supply Acc+B is at low potential or OV.
When this happens, the forward rotation of the C motor is stopped following the AND circuit (ANDl) and the motor control circuit (207).

In addition, when the accessory power supply Acc+B is in a low potential or Ov state for a certain period of time or more, the capacitor (C5) is sufficiently charged and its terminal potential reaches a predetermined potential, and N07

Although the embodiments of the present invention have been described above, various effective modifications can be made based on the technical ideas of the present invention.

(The following is the margin, continued on the next page.) Effect of the invention The present invention has the following effects.

(2) Since the cassette retracting and mounting mechanism is moved forward by the forward rotation of the capstan drive motor, and the cassette retraction and mounting mechanism is moved backward by the reverse rotation of the capstan drive motor, there is no need for a dedicated motor for loading, and the device can be made more compact.

■The capstan drive motor is driven to rotate in the forward direction by suppressing the tape travel push button switch during playback, etc.
This forward rotation drive causes the tape cassette retracting and mounting mechanism to move forward and loading the tape cassette to the cassette mounting position. , remote control including loading of tape cassettes can be easily realized.

(2) Moreover, since the tape cassette is loaded into the tape loading position by the positive rotation drive of the capstan drive motor by the suppressing operation of the tape running push button switch for playback etc. as described in (2) above, it is not possible to remotely There is no need to put the tape cassette in a fully loaded state before operation, and tape running such as loading and playback can be performed with a single operation, which is convenient for remote control.

(2) Also, from the above item 0, the capstan drive motor is driven to reverse rotation by the suppressing operation of the eject push button switch, and the cassette retracting and mounting mechanism is moved back and the tape cassette is ejected, so that the tuner is ejected. Since the tape cassette can be automatically ejected in the on state, mutual priority operation with the tuner is possible, and operability with the tuner can be improved.

Furthermore, unlike the conventional example, even if the tape cassette is ejected, it can be loaded again by remote control based on item 0 above. By storing the data, it can be used in various ways, such as being able to load it and play it back at a predetermined time, making the system extremely easy to use.

The cassette retracting and mounting mechanism in the present invention includes, for example, the cassette lifting mechanism (141) and the automatic retracting mechanism in the embodiment, and the control circuit in the present invention includes, for example, the motor control circuit (207) and the AND circuit (ANDl) in the present embodiment. ) (AND2), operation flip 70 circuits (FF4) (FF5), etc.
