Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a movable member control device incorporated in, for example, a tape recorder or the like so that a movable member can be controlled in two states by a single electromagnet.

(Problems to be Solved by Conventional Techniques and Inventions) Conventionally, a movable member movable between first and second positions is engaged with a drive member to move from the first position to the second position, and Movable member control devices for holding the second position are known.

In such a conventional movable member control device, the electromagnet for engaging the movable member with the driving member and the movable member are provided as the second member.
And an electromagnet for holding it in position. In the case where two electromagnets are provided as described above, a current switching circuit for selectively passing a current through the two electromagnets is required in order to suppress the increase in the current capacity and the amount of heat generation.
In addition to the complicated structure, a large space for disposing them is required, and there is a problem in reducing the size and weight.

In order to solve such a problem, one electromagnet having two attracting portions is provided, and this electromagnet has both the function of engaging the movable member with the driving member and the function of holding the movable member in the second position. It is possible.

However, if one electromagnet is made to have the above-mentioned two functions, the attraction force becomes weak when the attracted pieces corresponding to these two magnets are simultaneously attracted to the two attracting portions of the electromagnet. The capacity of the electromagnet has to be increased accordingly, and there is a problem in that it is expensive and consumes a lot of power, which is uneconomical.

The present invention has been made in view of the above circumstances, and has a small capacity.
The movable member can be reliably controlled by two electromagnets, the current switching circuit that was conventionally provided is not required, and the configuration is simple and compact.
It is an object of the present invention to provide a movable member control device that is effective in achieving weight reduction.

(Means for Solving the Problems) The present invention relates to a movable member that is movable between first and second positions by using an electromagnet with respect to a driving member that is driven by a driving source to perform a certain operation. A movable member control device that moves the first position to the second position by combining them and holds the second position, wherein the first and second movable members are respectively attracted to and moved by the first and second attracting portions of the electromagnet. (2) A piece to be attracted is provided, and the movable member is movable to and disengageable from the drive member, and the engagement state with the drive member is held by the first piece to be attracted that is attracted to the first attracting portion. For engaging part, and the second
A position-holding engaging portion that engages with the second attracted piece attracted to the attracting portion to hold the movable member at the second position, and the first attracted portion when the movable member reaches the second position. A separating portion for forcibly separating the piece from the first suction portion, and further, the moving engaging portion is provided with the movable member until the movable member reaches the second position from an intermediate position between the first and second positions. It is characterized in that a separation preventing portion for preventing separation from the driving member is provided.

Further, when the movable member is between the first position and immediately before the second position, the movable member includes a separated position holding portion that holds the second suction piece at a position separated from the second suction portion. Should be installed in

(Operation) By the first attracted piece being attracted to the first attracting portion of the electromagnet, the moving engaging portion holds the engaged state of the movable member and the driving member at the first position, and the driving member is driven. The driving force of the member causes the movable member to move from the first position to the second position. Then, after the movable member moves toward the first and second positions and the moving engagement portion reaches the separation prevention portion, and before the movable member reaches the second position, the first attracted piece pulls apart. Is forcibly separated from the first suction portion by the. Even if the first attracted piece is pulled away from the first attracting portion, the detachment preventing portion prevents the moving engaging portion from being detached from the driving member. The engagement state with the drive member is not released.

In this way, since the first attracted piece is separated from the first attracted portion, the magnetic flux is concentrated on the second attracted portion side, and the second attracted piece is strongly attracted to the second attracted portion. The movable member is held at the second position by the holding engagement portion.

Further, in the case of claim 2, while the first sucked portion is sucked by the first sucked portion, the second sucked portion is not sucked by the second sucked portion and is held in a separated state. The magnetic flux is concentrated on the side of the first attracting portion, and the first attracted piece is strongly attracted to the first attracting portion. As a result, the engagement between the drive member and the moving engagement portion can be reliably retained in combination with the action of the separation prevention portion,
The driving force of the driving member ensures that the movable member moves to the second position.

Slidably engaged with. The second cam gear 42 has a toothless portion 42a at one location. The second cam gear 42 meshes with the small diameter gear 27. Then, the second cam gear 42
The counterclockwise rotation of the lever causes the swing lever 39 to rotate in the clockwise direction by the action of the cam 43, and accordingly, the pull arm 37 rotates in the counterclockwise direction to engage one end of the pull arm 37. The slide lever 36 is pulled and slides in the second position direction (direction of arrow C) via the rotation lever 34 with which the piece 37a is engaged with the engagement recess 35. With the slide of the slide lever 36, the head mounting plate 15 is pressed and moved in one direction (direction of arrow A) via the head pushing spring 44. The head pushing spring 44 has one end hooked on a spring hooking portion 36a at the other end of the slide lever 36, and the other end hooked on a spring hooking portion of a pressing body 60 for pressing the head mounting plate 15.

When the slide lever 36 is sucked by the second suction portion 29b of 9, the slide lever 36 is held in the state of being slid to the second position (the state of FIG. 5). The slide lever 36 is the head pushing spring 4
4, it is urged in the first position direction (direction of arrow D). Therefore, when the electromagnet 29 is turned off, the slide lever 36 is slid back to the first position by the urging force of the head pushing spring 44 and enters the state shown in FIG.

A part on one end (upper end in the figure) side of the engaging groove (position holding engaging portion) 47 on one side edge of the slide lever 36 is a separated position holding portion 48. Then, the slide lever 36
Is between the first position and the position immediately before the second position, the second armature 31 has the following because the engaging portion 31b of the second armature 31 is in contact with the separated position holding portion 48.
The attracted portion 31a is held at a position separated from the second attracted portion 29b of the electromagnet 29. A stopper wall 49, which is a separation preventing portion, is provided at one side edge portion (right side edge portion in the drawing) of the base frame 28. When the slide lever 36 is located between the first and second positions and the second position, the engagement wall 50 provided on the lower surface of the rotation lever 34 engages with the stopper wall 49. The rotation lever 34 by
The engaging concave portion 35 is prevented from being disengaged from the engaging piece 37a of the pull arm 37. Rotating lever 3
An inclined wall 51, which is a separation portion, is integrally provided on the upper surface of 4 so as to project. The inclined wall 51 is provided after the slide lever 36 moves from the first position to the second position and the rotation lever 34 reaches the stopper wall 49 and before the slide lever 36 reaches the second position. First armature 3
0 is forcibly separated from the first attraction portion 29a of the electromagnet 29.

Next, the operation will be described.

FIG. 1 shows a stopped state. In this state, when the tape cassette is loaded in the operating position, a motor switch (not shown) is turned on in association with the loading operation, and the motor 2 rotates. As the motor 2 rotates, both capstan shafts 4a and 4b are rotated in the directions of the arrows via the belt-type rotation transmission mechanism. When the play operation switch (not shown) is turned on after the completion of the tape cassette loading operation, the electromagnet 29 is turned on, and the first adsorption portion 29 is turned on.
When the attracted portion 30a of the first armature 30 is attracted to the a, the first armature 30 rotates counterclockwise, and at the same time, the rotation lever 34 causes the base end portion 34 of the rotation lever 34 to rotate.
It rotates counterclockwise around a as a fulcrum. By the rotation of the rotation lever 34, the pull arm 37 is inserted into the engagement recess 35.
The engaging piece 37a of is engaged. On the other hand, the second armature 3
In the first armature 1, the engaging portion 31b is in contact with the separated position holding portion 48 of the slide lever 36, so that the clockwise rotation is blocked. Therefore, the second armature 31 is the second armature 31 of the electromagnet 29. It is not adsorbed on the adsorption part 29b. As a result, the magnetic flux concentrates on the first adsorption portion 29a, and the first adsorption portion 2a
The attracted portion 30a of the first armature 30 is strongly attracted to 9a. On the other hand, since the second cam gear 42 has already meshed with the small diameter gear 27 in the stopped state (state of FIG. 1), the rotational force of the motor 2 causes the first gear 6 of the gear type rotation transmission mechanism 5 to rotate. It is transmitted to the second cam gear 42 via the second gear 7, the third gear 8, the fourth gear 9 and the small diameter gear 27,
This second cam gear 42 is rotated clockwise. Along with the rotation of the second cam gear 42, the swing lever 39, which is in sliding contact with the cam 43 via the cam roller 41, rotates clockwise about the mounting shaft 40 from the state shown in FIGS. 1 and 3. To do. By this rotation of the swing lever 39, the pull arm 37 rotates counterclockwise from the state shown in FIGS. 1 and 3. Since the engagement piece 37a of the pull arm 37 is engaged with the engagement recess 35 of the rotating lever 34, the pull arm 3
With the rotation of 7 in the counterclockwise direction, the slide lever 36 integrally with the rotation lever 34 is located in the first position shown in FIGS. 1 and 3 in the arrow C direction (the second position direction). Moving. Then, when the slide lever 36 reaches the second position from the middle between the first and second positions, the engagement wall 50 of the rotating lever 34 becomes the stopper wall 49 of the base frame 28 as shown in FIG. By engaging, the rotation lever 34
The engagement concave portion 35 is prevented from being disengaged from the engagement piece 37a of the pull arm 37 (state of FIG. 4).

Such a state of FIG. 4, that is, the engagement wall 50 of the turning lever 34.
When the slide lever 36 is still moved in the second position direction after being engaged with the stopper wall 49, the inclined wall 51 on the upper surface of the rotation lever 34 causes the first armature 30 and the electromagnet 29 to move to the first position. By interposing with the suction portion 29a, the first teamature 30 is forcibly separated from the first suction portion 29a. As a result, the magnetic flux concentrates on the second attracting portion 29b of the electromagnet 29. In this way, at the same time when the slide lever 36 reaches the second position, the engaging portion 31b of the second armature 31 engages with the engaging groove 47 of the slide lever 36, so that the second armature 31 moves to the timepiece. By rotating in the direction, the attracted portion 31a is attracted to the second attracting portion 29b of the electromagnet 29, and the slide lever 36 is held at the second position (state of FIG. 5). In this case, as described above, since the magnetic flux is concentrated on the second attracting portion 29b of the electromagnet 29, the second armature 31 is strongly attracted to the second attracting portion 29b.

In this way, the slide lever 36 moves from the first position to the second position.
As the head push-out spring 44 rotates counterclockwise as it moves to the position, the head mounting plate 15 moves in the direction of arrow A against the urging force of the head return spring 17 in accordance with this rotation. The magnetic head 16 contacts the tape of the tape cassette. When the moving plate 21 is in the position moved in the direction of the arrow C when the head mounting plate 15 is moved to the play position (state of FIG. 1), the moving plate is moved as the head mounting plate 15 moves to the play position. The support member 18 moves in the direction of arrow C together with the switching gear 19 for low speed rotation by being guided by the guide edges 22b and 22a of the guide hole 22 of the low speed rotation switching gear 19.
Meshes with the sixth gear 9 of the gear-type rotation transmission mechanism 5 and the reel gear 14b for low speed rotation on the other reel receiver 3b side.
As a result, the rotational force of the motor 2 causes the first gear 6, the second gear 7, the third gear 8, the fourth gear 9, the fifth gear 10, the sixth gear 11, and the low speed rotation of the gear type rotation transmission mechanism 5 to rotate. It is transmitted to the other reel receiver 3b through the switching gear 19 and the other low speed rotation reel gear 14b, and the other reel receiver 3b is rotated counterclockwise at a low speed (normal speed).
Further, when the moving plate 21 is at the position moved in the direction of arrow C, the other pinch roller contacts the other capstan shaft 4b via the tape and rotates clockwise, and at the same time, the one pinch roller. Is one capstan shaft 4
Do not touch a. As a result, the play operation is performed while the tape is being wound from the one reel receiver 3a side to the other reel receiver 3b side.

Further, when the moving plate 21 is in the position moved in the direction of the arrow D when the head mounting plate 15 is moved to the play position, the guide hole 22 of the moving plate 21 is moved along with the movement of the head mounting plate 15 to the play position. The support member 18 is guided by the guide edges 22d and 22c so that the support member 18 moves at a low speed rotation switching gear 19
By moving together in the direction of arrow D, the low-speed rotation switching gear 19 meshes with the eighth gear 13 of the gear-type rotation transmission mechanism 5 and the low-speed rotation reel gear 14a on the reel receiving side 3a side. As a result, the rotational force of the motor 2 causes the gear type rotation transmission mechanism 5 to have the first gear 6, the second gear 7, the third gear 8, the fourth gear 9, the fifth gear 10, the seventh gear 12, and the eighth gear.
It is transmitted to one reel receiver 3a through the gear 13, the low speed rotation switching gear 19 and one low speed rotation reel gear 14a, and the one reel receiver 3a is rotated clockwise at a low speed.

Further, when the moving plate 21 is at the position moved in the direction of arrow D, one pinch roller moves one capstan shaft 4
While being in contact with a through the tape and rotating in the counterclockwise direction, the other pinch roller does not contact the other capstan shaft 4b. As a result, the tape is placed on the other reel receiver 3
The play operation is performed while being wound from the b side to the one reel receiver 3a side.

In such a play operation state, when a stop operation switch (not shown) is turned on, the energization of the electromagnet 29 is cut off and demagnetized. As a result, the slide lever 36 is
It is slid back to the first position by the biasing force of the head pushing spring 44. As the slide lever 36 slides in the first position direction, the engagement wall 50 of the turning lever 34 disengages from the stopper wall 49. As a result, the first armature 3
0 is rotated clockwise in the figure by the urging force of the spring, and the attracted portion 30a is held in a state of being attracted to the first attracting portion 29a of the electromagnet 29. In addition, the slide lever 36 is the first
As it slides in the position direction, the second armature 3
When the first engaging portion 31b comes out of the engaging groove 47 of the slide lever 36 and comes into contact with the separated position holding portion 48, the second armature 31 resists the urging force of the return spring 46 in the drawing. The attracted portion 3 is rotated counterclockwise.
1a is held in a state of being separated from the second attracting portion 29b of the electromagnet 29, and the stopped state shown in FIGS. 1 and 3 is again established.

In addition, in the above-described embodiment, the separating portion 51 is provided in the moving engagement portion 34, but the invention is not limited to this, and the separating portion 51 may be provided in the movable member 36.

As described above, according to the present invention, the movable member is moved from the first position to the second position by one electromagnet having a small capacity,
In addition, it is possible to surely perform the control of holding the second position. Further, since only one electromagnet is required, the current switching circuit, which has been conventionally required, is not required, and the configuration is simple in combination with the fact that only one electromagnet is required, and it is effective in achieving reduction in size and weight.

According to the invention of claim 2, the movable member is the first
When the movable member is located between the position and the position immediately before the second position, the movable member is provided with a separated position holding portion that holds the second attracted piece at a position separated from the second attracted portion. Since the magnetic flux can be concentrated on the side of the first attracting portion that is required when moving from the first position to the second position, the first attracted piece can be strongly attracted to the first attracting portion. Therefore, the moving engagement portion can be stably and reliably engaged with the drive member without increasing the capacity of the electromagnet, and the drive force of the drive member can surely move the movable member to the second position. .
