And a tape drive driving motor connected to the other terminal of the power supply by connecting the pole of the other side to the other terminal of the power supply, and the cassette holder being inserted between the second fixed contact of the motor switch and one terminal of the power supply. It is in the ON state when the cassette is in the long position, and is rotationally driven to the switching switch and the motor in the OFF state when the cassette holder is in the cassette ejection position. The main rotating body, the driven rotating body is not engaged with the main rotating body in a certain angle range, and when the main rotating body is engaged with the main rotating body, the driven rotating body is rotated by the rotational force, and the main rotating body given through the driven rotating body An actuating mechanism for operating the cassette holder from the cassette long position to the cassette ejecting position by the rotational force, and at the same time maintaining the driven rotary body in a constant angle range not engaged with the main rotary body, and simultaneously operating the motor switch. The contact point is held on the second fixed contact shaft, and the movable contact of the motor switch is returned to the first fixed contact shaft by manual operation, and at the same time, the driven rotary body is opened to engage with the main rotating body to operate the jack mechanism. Afterwards, maintain the driven rotor at a certain angle range not to be engaged with the main rotor, and at the same time Is one characterized in that it comprises a control such as the rotation transmission member to maintain the same contact point toward the second fixed contact.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a plan view, and a pair of rail shafts 2a and 2b, capstan shafts 3a and 3b, and a rotational drive thereof are provided on the upper surface side of the main board 1. A tape drive mechanism including a motor 4 is mounted, and the motor 4 simultaneously rotates both capstan shafts 3a and 3b in the direction of tape transmission, and simultaneously rotates a pair of rail shafts 3a and 3b. Alternatively, the tapes are rotated in the respective winding directions.

On the upper surface of the main board 1, magnetic heads 5 for recording and reproduction, and pinch rollers 6a and 6b corresponding to the capstan sides 3a and 3b are attached.

In addition, a cassette holder 7 is mounted on the upper surface of the main board 1, and the cassette holder 7 is a rotating plate which is rotated in an up and down direction (direction perpendicular to the ground) with the left end surface as the axis in FIG. (8) and the cassette inserting body 9 etc. which were supported by the rotating material in the up-down direction (direction orthogonal to the surface) with the right end surface of this rotating plate 8 as an axis | shaft.

On the other hand, the amount of rotation in the upward direction of the rotating plate 8 is regulated by the stopper 10 formed above the shaft wall of the main plate 1, and the rotary plate 8 and the cassette insert ( 9) remains substantially parallel with the main board 1 where it is moved upwards.

The cassette insert 9 includes a cassette inserting hole 11 on the right end side in FIG. 1, and the tape cassette 12 can be inserted or removed through the cassette inserting hole 11. Then, as the pivoting plate 8 is rotated downward while the tape cassette 12 is inserted into the cassette insert 9, the tape cassette 12 is the rail shafts 2a and 2b and the capstan. It is charged with the axes 3a and 3b.

Here, the position at which the rotary plate 8 rotates downward to advance the tape cassette 12 to the rail shafts 2a and 2b and the capstan shafts 3a and 3b is referred to as the "cassette extension position" of the cassette holder 7. The rotating plate 8 is rotated upward, and the position where the cassette cassette 12 can be inserted in the cassette inserting hole 11 is referred to as the "cassette discharge position" of the cassette holder 7.

When the magnetic head 5 moves from the cassette discharge position of the cassette holder 7 to the cassette long position, it moves in the downward direction in FIG. 1 in conjunction with this, and is inserted into the tape cassette 12 to insert the magnetic It comes in contact with the tape.

When the magnetic head 5 is inserted into the tape cassette 12 in this manner, the pinch roller on the same side as the rail shaft on the side driven by the motor 4 is pressed against the capten shaft on the same side in conjunction with this. become. For example, when the right shaft single shaft 2a is being driven, the right shaft pinch roller 6a comes into contact with the right capstan shaft 3a.

In addition, a tool insertion hole 74 is drilled in a part of the driven rotating body 45, and the tool operation unit substrate (42a) is inserted into the hole 74 by inserting a tool such as the screw 42 and the driver (42a). The main board 1 of FIG. 42 can be mounted (refer to FIG. 6).

Next, the relationship between the motor 4, the motor switch 49, and the switching switch 50 will be described with reference to FIG.

On the other hand, Fig. 7 (a) shows a state in which the tape recorder is stopped, and one pole 4a of the motor 4 is connected to one terminal 75a of the power supply to the first switch of the motor switch 49. Figs. It is connected via the fixed contact 49b, the movable contact 49a, etc., and the other pole 4b of the motor 4 is connected with the other terminal 75b of a power supply.

Moreover, the 2nd fixed contact 49b of the motor switch 49 is connected to the one terminal 75a of a power supply via the said switching switch 50. As shown in FIG.

The elasticity of the spring 54 is given to the movable contact 49a of the motor switch 49 through the rotation transfer control member 46, whereby the movable contact 49a is always the first fixed contact 49b. When the tape recorder is in a stationary state, the tape recorder is in contact with the second fixed contact 49c by the action of the driven rotating body 45, as described later.

On the other hand, the relation between the driven rotating body 45, the rotation transmission control member 46, the power transmission member 47, the torsion spring 73 and the pressure transmission member 25 is as shown in Fig. 7 (b) It is.

FIG. 7 (b) shows the state in which the tape recorder is stopped in correspondence with the same drawing (a). The torsion spring 73 is pressed against the top end of the hydraulic projection 71, and the driven rotating body 45 is shown. Torque in counterclockwise direction (arrow display direction).

Further, the trigger catching pin 57 of the rotation transmission control member 46 is engaged with the stop position retaining projection 69, whereby the rotation of the driven rotating body 45 in the counterclockwise direction is prohibited.

In the rotation transfer control member 46, the rotation of the clockwise direction by the spring 54 is prohibited by the contact between the cam pin 56 and the stop position holding recess 68. As shown in FIG.

Then, the switch contact pin 58 of the rotation transfer control member 46 holds the movable contact 49a of the motor switch 49 on the second fixed contact side as shown in FIG.

The power transmission member 47 has the cam roller 60 facing the lowest portion of the spiral winding 66, and the bending pin 25a having the transmission member engagement pin 58 formed on the pressure transmission member 25. It is opposed to receive the elasticity of the return spring 28 (see FIG. 2).

In Fig. 7 (b), reference numeral 77 denotes a main gardeniac as a main rotating body mounted on the main board 1 as a rotating material.

This main gear 77 is always connected to the motor 4 through the motor pulley 78, the endless belt 79, the intermediate fleece 80, and the intermediate teeth 81 and 82, as shown in FIG. It is supposed to drive.

The main gear 77 engages with the gear 64 of the driven rotary body 45, but in the state of FIG. 7 (b) in which the tape recorder is stopped, the driven rotary body 45 The notch 65 faces the main gear 77, and the rotational force transmission path from the main gear 77 to the main rotating body 45 is broken.

83 in the sixth figure is an endless belt for transmitting the rotational force of the motor 4 to the tungsten shafts 3a and 3b via the motor pulley 78. The rotational force of the motor 4 is also selectively transmitted to the rail sides 2a and 2b via the gardenia teeth 81 and 82.

Returning to the description of FIGS. 1 and 2 again, on the outer surface of the side plate of the main board 1, the pressing force transmission member 25 and the overlaid actuator operating member 84 are shown in FIGS. 1 and 2. It is attached to the retreat material in the left and right directions.

This ejection operation member 84 is supported in the right direction in the drawing by a return spring 85 that has been crossed between the main board 1.

Then, the ejection control member 84 is pressed against the return spring 85 in the left direction to press the engaging pin 55 of the rotational transmission control member 46 to press the control member ( 46) is rotated counterclockwise.

Next, the operation of FIG. 1, FIG. 2 and FIG. 7 (a) (b) indicates the stop state, in which the ejection member 16 is the elasticity of the eject spring 18. In FIG. It is moving in the return direction (right direction in the drawing) by the.

In addition, the cassette holder 7 is located at a stop position away from the main board 1, and the engaging portion 23 of the holding member 21 is engaged with the upper surface of the side plate of the main board 1 so that the cassette of the cassette holder 7 can be connected. It is forbidden to move to Jangjin position.

In addition, the spring support member 15 receives the elastic force of the return spring 28 through the connecting rod 27 and the pressure transmission member 25, and therefore in the return direction (the direction in which the eject spring 18 is enclosed). I'm moving.

On the other hand, the operation force transmission member 29 connects the engagement pin 33 to the engagement protrusion 40 of the moving member 34 to prohibit the return operation in the right direction in the drawing by the return spring 30. have. The operating force transmitting member 29 rotates the switch operating member 48 counterclockwise at this position, and maintains the switching switch 50 in the OFF state.

On the other hand, the interlocking member 34 is rotated in the counterclockwise direction (the direction of moving the cassette holder 7 to the cassette long position) in the drawing by receiving the elasticity of the return spring 30 and the cassette push spring 41, Rotation in that direction is prohibited by fitting the long groove 36 and the connecting pin 37 together.

The motor switch 49 has the movable contact 49a in contact with the second fixed contact 49c by the rotation transfer control member 46. In addition, the driven rotating body 45 is held in the first rest position by contact with the stop position holding projection 69 and the trigger catching pin 57 of the rotation transmission control member 46.

Therefore, when the tape cassette 12 is inserted into the cassette holder 7 in the cassette insertion hole 11 in the longitudinal direction, and inserted in the pin direction with the main pipe 1 substantially, it is on the insertion line of the tape cassette 12. The located ejection member 16 reciprocates against the resist spring 18.

When the amount of elastic deformation of the event spring 18 gradually increases and the amount of elastic deformation exceeds the position where the maximum amount of elastic deformation exceeds the maximum, the elastic force of the event spring 18 is this time. It acts to move (16) in the direction of movement.

Therefore, the force for press-ining the tape cassette 12 is unnecessary, and conversely, the tape cassette 12 enters into the cassette holder 7 by the elastic force of the eject spring 18.

Therefore, the event member 16 contacts the contact pin 22 of the fastening member 21, and rotates the fastening member 21 with respect to the pull spring 24. As shown in FIG.

Thus, the catching part 23 of the catching member 21 is released from the side plate upper edge of the main board 1 (see FIG. 3), and the rotating plate 8 and the interlocking member 34 of the cassette holder 7 Receiving the elastic force of the return spring 30 and the cassette press spring 41, and rotates downward, accordingly the cassette insert 9 is also lowered to the cassette extended position to move the tape cassette 12 to the rail side (2a, 2b) and It is extended to the capstan shafts 3a and 3b (see also FIG. 4).

As the cassette insert 9 descends, the magnetic head 5 moves in the tape cassette 12 direction to contact the magnetic tape.

3, 4 (side view of the third view in the direction of arrow IV) and 8 (a), (b) show the cassette loaded state, that is, the state in which the cassette holder 12 is moved to the operating position. In this state, the operation force transmitting member 29 returns to the right direction in the drawing by the return spring 30 in accordance with the rotation of the interlocking member 34.

Then, the switching switch 50 is switched by the movement of the switch operating pin 32, and the motor 4 rotates by the switching of the switching switch 50 (see FIG. 8 (a)).

Then, either one shaft 2a or 2b is rotated by the rotation of the motor 4, and both the capstan shafts 3s, 3b are rotated in the direction of tape winding, respectively, and the rotational driving is performed again. The pinch roller 6a, which is the same as the shaft (for example, 3a), is pressed against the capstan shaft 3a corresponding thereto to drive the tape to perform a regeneration operation.

When the tape is wound up to the end, a reverse mechanism (not shown) is operated to switch the tape running direction and then to perform a reproducing operation.

Next, when the stop and the tape cassette 12 are to be taken out, the eject operation member 84 is resisted against the return spring 85 and gently pressed to the left in the drawing, and then lifted.

At this time, the rotation transfer control member 46 is rotated counterclockwise once by pressing the eject operation member 84.

Therefore, the trigger catching pin 57 of the rotation transmission control member 46 is released from the projection 69 for maintaining the stop position of the driven rotational body 45, so that the driven rotational body 45 is resilient to the torsion spring 73. In the counterclockwise direction, in response to the contact between the cam pin 56 and the blocking position holding recess 70, the driven rotating body 45 is maintained at the second rest position shown in FIG.

At the same time, when the hand is released from the operation member 84, the rotation transfer control member 46 rotates clockwise by the spring 54 to maintain the cam pin 56 as shown in FIG. Loosen from convex (70).

Therefore, the driven rotary body 45 rotates clockwise by the pressing force of the torsion spring 73 to the place which contacts the main gear 77. As shown in FIG.

In response to the clockwise rotation of the rotation transfer control member 46, the switch operating pin 58 moves the movable contact 49a of the motor switch 49 as shown in FIG. 10A to the first fixed contact 49b. Switch to the side.

Therefore, the motor 4 is connected to the power supply through the first fixed contact 49b and the movable contact 49a, and the rotational force of the motor 4 is transmitted to the driven rotary body 45 through the main gear 77. do.

Then, by rotating the driven rotating body 45, the vortex winding 66 pushes the cam roller to rotate the power transmission member 47 largely in the counterclockwise direction as shown in FIG.

Therefore, the transmission member engaging pin 59 of the power transmission member 47 strongly pushes the bending pin 25a of the pressure transmission member 25, and the pressure transmission member 25 is formed of the operation force transmission member 29. The import unit 31 is pressed and the operation force transmitting member 29 is moved in the same direction.

Here, the switching switch 50 switches back to the OFF side (the side enabling the radio) as in the eleventh degree, and the engaging pin 33 presses the engaging projection 39 of the interlocking member 34 to This interlocking member is rotated clockwise in the fourth figure.

Therefore, the rotating plate 8 rotates in the counterclockwise direction, whereby the cassette insert 9 is raised to the cassette discharge position to move the tape cassette 12 to the rail shafts 2a and 2b and the capstan shafts 3a and 3b. ) Is pulled upwards.

In addition, the spring support member 15 is rotated counterclockwise, i.e., in the vertical direction in FIG. 3 through the connecting rod 27 by the movement of the pressure transmission member 25, and reverses the eject spring 18. As shown in FIG.

Therefore, the ejecting member 16 is moved in the right direction in the drawing by receiving the elastic force of the ejecting spring 18 and in the direction of taking out the tape cassette 12.

In addition, the fastening member 21 returns clockwise by the pulling spring 23a to hold the fastening portion 23 on the side plate upper edge of the main board 1.

On the other hand, the cam roller 60 is soon released from the spiral winding 66, and accordingly, the power transmission member 47 returns to the initial position by the return spring 28 as with the pressure transmission member 25. .

Then, the cam pin 56 of the rotational transmission control member 46 again climbs on the stop position holding portion 68 of the driven rotational body 45 to resist the rotational transmission control member 46 against the spring 54. By rotating clockwise, the movable contact 49a of the motor switch 49 is switched to the second fixed contact 49c side to stop the motor 4 (see FIG. 7 (a)).

At this time, the gear 64 of the driven rotary body 45 is loosened from the Far Eastern rotary body 77, but the pressing force of the torsion spring 73 acts on the hydraulic projection to move the driven rotary body 45 to FIG. 7 (b). Rotate to the initial position of.

If the automatic operation by the rotational force of the motor 4 and the operation of the operation are not performed due to the failure of the operation unit 24 or the like, the pressing force transmission member 25 is directly pushed to move it. It can be used for automatic stop and event operation.

As described above, the motor operation 49, the switching switch 50, the rotation transmission control member 46, and the like are integrally attached to the operation operation unit engine 42 to unitize the operation operation unit engine ( 42 can be easily assembled by simply fixing the screws 42a and 42b to the main board 1, and repair, inspection and the like can be facilitated.

As described above based on the embodiments, the present invention is not necessarily limited to the above embodiments. That is, with respect to the relationship between the driven rotary body 45 and the rotation transfer control member 46, as shown in FIG. 13, the stop position holding recess 68 and the stop position holding projection 69 of the driven rotary body 45. ), The stop position holding projection 69 and the trigger engagement pin 57 corresponding thereto can be omitted.

As described above, the present invention can not only perform the operation of the tape cassette by using the rotational force of the motor for driving the tape, but also can stop the motor until the end of the operation of the tape, thus eliminating the trouble of double operation. It is to provide a cassette tape record for materials that do not exist.
