Description

[Detailed Description of the Invention] This invention relates to a tape recorder device oriented toward miniaturization.
Especially regarding those with improved operability.

Recently, tape recorders are small and light, making them suitable for carrying, and 2-way recorder types have become popular, especially for playback using headphones. For example, it is possible to enjoy the tape μfiIE while walking. Such portable cheap recorders, which are exclusively used for headponging, have already been made as small as possible, and are currently about the same size as a cassette case that houses a tape cassette.

By the way, if the size is reduced to approximately the same size as the entire tape recorder cassette case, the next requirement is:
It is time to completely improve the shape and arrangement of the various operating elements for putting the tape recorder into various operating states such as playback, fast forwarding, nine rewinding, etc., as well as the stop state, to further improve operability and ease of use. In other words, the controls of conventional compact tape recorders are small in proportion to the tape recorder body, and are concentrated in one place due to the relationship with the tape recorder mechanism. However, it is easy to cause erroneous operation. Therefore, while the tape recorder itself has traditionally been downsized to approximately the same size as a cassette case, the shape and arrangement of the controls have been designed to be thick enough for the user to easily create and fit, and, for example, The development of a compact tape recorder that is not only convenient to carry, but also has excellent operability, with wide spacing so that adjacent controls cannot be accidentally operated is ff! 'ii highly desired.

The present invention has been made based on the above circumstances, and an object of the present invention is to provide an extremely good tape recorder device that has a simple configuration, improves operability, and effectively promotes miniaturization.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 shows the appearance of a tape recorder to which the present invention is applied. That is, the cabinet 11 is approximately box-shaped and has approximately the same size as a cassette case that accommodates tape cassettes. The front surface of the cabinet 11 serves as a cassette lid 12, which rotates in the directions of arrows A and B in the figure for opening and closing operations. That is, the cassette lid 12 is always urged in the direction of the arrow B by a spring (not shown), and when it is rotated in the direction of the arrow B against the urging force, it is locked by a lock portion (not shown) provided on the cabinet 11. and the closed state. Then, by operating an ejector operator (not shown) provided on the side surface of the cabinet 11, the lock by the lock section is released, and the cassette lid 12 is rotated in the direction of the arrow by the biasing force of the spring and opened. Nasari, Ru.

Here, as shown in FIG. 2, inside the cabinet 11, there is a tape cassette storage section 14 for storing the tape cassette 13 indicated by a dashed line in the figure, a circuit section of a tape recorder mechanism section 9, a head section, A mechanism storage section 15 is provided in which a battery storage section and the like are mounted. In the tape cassette storage section 14, a pair of reel shafts 16, 1v (second
In the figure, only the reel shaft 17 (only the reel shaft 17 is shown) is provided in a protruding manner.

Here, as shown in FIG. 1 again, approximately in the center of the cassette lid 12, there are provided an operating section 18 and a window section 19 for putting the tape recorder into playback, fast forwarding, rewinding, and stopping states. It is being Of these, the operation section 18I-i
, playback, fast forward 2, rewind and stop controls 2o to 2
The details will be described later, but the cassette red 12
It is attached so that it can be slightly suppressed. As shown in FIG. 2, the playback operator 2o is provided on the tape exposed surface of the tape cassette 13, not facing the flat surface of the tape cassette 13 of the cassette M12. In addition, the above-mentioned fast forward and rewind operator 21゜2
2 is a reel shaft 16 which becomes the winding side during fast forwarding and rewinding.
．． 17, respectively, so as to include the rotation axes 161° and 171 thereof. Further, the stop operator 23 is configured to include the fast forward and rewind operators 21 and 22.
is set between.

On the other hand, the window portion 19 is formed by, for example, a transparent acrylic machine, and is arranged so as to overlap at least a portion of a well-known tape see-through window formed on the flat surface of the tape cassette 13. . That is, the first window portion 19
The left end in the figure overlaps a part of the reel shaft 16, 17, and the running state of the tape can be visually observed from the outside through the tape see-through window. In short, the boundary between the operating section 18 and the window section 19 is the reel shaft 16.
．． It is sufficient if it is located above 17. Furthermore, in order to visually observe the tape running state from the outside, the operating section 18 may be made of a transparent material.

Here, in the cassette lid 12, a tapered portion is provided between the playback operator 20 and the fast forward, one rewind, and stop operators 21 to 23, which spread outward from the tape cassette storage section 14 side. A long hole 24 is formed. This elongated hole 24 is provided so that a tuning operation can be performed with the cassette lid 12 closed during radio reception using the tuner unit. That is, this tape-on coder is not only capable of simply reproducing tapes, but also can receive radio broadcasts by using a tuner unit. This uses a tuner unit i, in which a tuner circuit section for receiving, tuning, detecting, and amplifying radio waves is housed in a casing that has approximately the same shape as the tape cassette.
This is done by mounting the tape cassette in the tape cassette storage section 14 instead of the tape cassette. When a desired broadcasting station is selected by operating the tuning dial provided on the tuner unit, the received radio waves are detected and amplified, and then introduced into the main amplifier circuit in the tape recorder via the connection terminal. This is where the radio broadcast is received. At this time, with the cassette lid 12 closed, the channel selection dial is projected to the outside through the elongated hole 24, and the channel selection operation can be performed without opening the cassette dial 12. .

Reference numeral 25 in FIG. 1 is a tape-radio selection switch, and when the tuner unit is installed and the tape-radio selection switch 25 is set to the radio side, the playback, fast forward and rewind controls 20 to 22 are operated. The motor is also designed not to rotate while the tape is running, which helps to save electricity. Furthermore, although not shown in the drawings, the cabinet 1) is provided with a sound adjustment dial, a switch for tape type (normal, chrome, metal), a headphone jack, etc., although not shown.

Here, the above-mentioned fast forward 2 rewind and stop operators 2 to 2
The attachment of No. 3 to the cassette lid 12 will be explained. That is, as shown in FIG. 3, a long hole 26 is formed approximately at the center of the cassette lid 12. As shown in FIG. A pair of bearing portions 261, 261 (only one bearing portion 261 is shown in FIG. 3) is formed at one end of the elongated hole 26.

Then, in the elongated hole 26 of the cassette lid 12, fast forward, rewind, and stop operators 21 to 23 as shown in FIG.
is to be installed. That is, the fast-forwarding, rewinding, and stopping operators 21 to 23 are each substantially rectangular plates, and bearing portions 21 to 231 are formed at one end of each of them. Each bearing has a shaft (not shown) passing through the portions 211 to 23, and both ends of the shaft are connected to the bearings of the cassette lid 12 at the portions 261 and 23.
1, each of the operators 21 to 23 is attached.

Further, the fast forward and rewind operators 21 and 22 are the fifth
As shown in the figure, when the cassette lid 12 is in the open state fc,
For example, the end of the bearing opposite to the side where the parts 211 and 221 are formed is formed at one end of the elongated hole 26 of the cassette lid 12 so that it does not sag when rotated in the direction of the arrow in the figure. It is shaped so that it can be locked in a locking part (not shown).

Further, on the surface of the fast forward/rewind operator 21.22 facing the tape cassette storage section 14, a protrusion 212 is provided at a portion facing each tip of the pair of reel shafts 16.17.
222 are formed respectively. When the cassette lid 12 is closed, the protrusions 212 and 222 move onto the reel shaft 16.
．． 17, both operating elements 21, 22 are pushed back slightly outward. For this reason, there are two fast-forward and rewind controls.

When the reel 22 is depressed, the reel shafts 16 and 17 are pressed in the axial direction, thereby fast forwarding and rewinding the tape.

Furthermore, as shown again in FIG.
3,223 are formed. On both sides of the stop operator 23, the protruding pieces 213 and 223 are provided.

Either the fast-forward and rewind operators 21, 22 are both suppressed, or the operation stroke at this time is shorter than the stroke when the fast-forward and rewind operators 21, 22' (r-operate alone). This is regulated by a stop slider, which will be described later.

Next, we will explain how to install the arresting operator 20.
do. First, Figure 6 shows the previous day's [2 tape recorder mechanism structure 11i!] The birth control device 20 is provided at the lower part of the main chassis 27 in the figure as shown by two points 1'lhy. And this main chassis 27
A head chassis 28 is provided on the right side of the playback operator 20 in the figure. This head chassis 2817J
:, by being supported by the rotation shaft 29 fitted to the right end in the figure or the main chassis 27, the arrow C1D in the figure
It is rotatably supported in the direction. Furthermore, a reproducing head 30 is scattered at the left end of the helad chassis 28 in the figure. Furthermore, a portion of one end of the pinch lever 31 is rotatably supported on the rotation shaft 29. A pinch roller 32 is rotatably supported 11 at the other end of the pinch lever 3).

Here, as shown in FIG. 7, one end of the helad chassis 28 is attached to one side of the helad chassis 28, and the other end is attached to the main chassis 27 by fully winding the rotating shaft 29. The torsion spring 33 is engaged with a protruding portion (not shown), and is biased to rotate about the rotation shaft 29 in the direction indicated by the arrow in the figure. In addition, a coiled spring 34 is engaged between the pinch lever 311d, the protruding piece 281 formed on one side of the head chassis 28, and the other end of the pinch lever 31.
It is urged to rotate about the rotation shaft 29 in the direction of arrow C in the figure at j-. This rotation of the pinch lever 31 in the direction of arrow C is such that the other end of the pinch lever 31

Furthermore, a projecting piece 282 is formed on the second dl:-head chassis 28 at a position corresponding to the rear end of the playback head 300. This protruding piece 282 is brought into contact with one end portion of the rivet driving portion ladle 35, which is formed in an oval shape on the side. Here 1. As shown in FIG. 8, the regeneration drive member 35 has a shaft 36 formed in the mechanism storage portion 15 that passes through a corner of the regeneration canter 35 at the middle lower part of the main chassis 270. This allows it to be rotatably supported. The regeneration drive part shrine 35 has its one end abutted against the side wall (not shown) of the mechanism storage part 15, so that the regeneration drive part shrine 35 can withstand rotation in the clockwise direction in the figure until it reaches the position shown in FIG. regulated. Therefore, the head chassis 28, which is biased in the direction of the arrow in FIG. 7 by the torsion spring 33, is rotated to the position shown in FIG. 8.

On the other hand, one end of an operating shaft 37 is scattered at the lower part of the playback operator 20 in FIG. The other end of the operating shaft 37 is exposed toward the center in the figure, and a substantially circular IJ-shaped bearing formed in the cabinet 11 is inserted through a portion 38; It is supported so that it can slide in the middle and up and down directions. Further, the bearing of the operating shaft 37 is inserted into the portion 38 at the lower end in the figure, and is provided with a substantially conical first driving portion 39.
The bottom surface of is sorbed. The top of the first drive section 39 is connected to a substantially conical second drive section 410 via a shaft 4θ having a smaller diameter than the operating shaft 37. The bottom surface of the second drive section 41 faces the other end of the regeneration drive section ladle 35.

Here, the operation shaft 37. The first drive part 39° shaft 40 and the second shaft 40 are formed on the main chassis 27. It is inserted through the through hole 271 and can freely slide downward in FIG. In addition, the playback operator 2
A coil-shaped spring 42 is interposed between the lower end of the bearing part 38 in the figure and the step part 381 formed at the upper part of the bearing part 38 in the figure. However, the movement of the playback operator 20 upward in the figure is as follows.
The curved surface of the first drive section 39 comes into contact with the lower end of the bearing section 38 in the drawing. Here, the operation shaft 37
．． The first drive section 39, the shaft 4θ, and the second drive section 41 are
For example, it may be integrally formed by molding a synthetic resin material. In this case, the bearing of the operating shaft 37b may be inserted through the portion 38 from below in the figure and connected to the reproducing operator 20.

Now, assume that the playback operation element 20 is pressed downward in the figure against the biasing force of the spring 42 from the state shown in FIG. Then, as shown in FIG.
The other end of the regeneration drive member 35 is pressed by the bend of , and the regeneration area moving portion 235 is rotated counterclockwise in FIG.

For this reason, one end of the playback drive part ladle 35 presses the protruding piece 282 of the head chassis 28, and the head chassis 28 is rotated in the direction of arrow C in FIG. 7 against the biasing force of the torsion spring 33. Ru.

At this time, the reproducing head 30 is brought into contact with a tape (not shown) of the tape cassette, and the pinch roller 32 is pressed against a capstan, which will be described later, through the tape. Here, when the pinch roller 32 is pressed against the capstan, the pinch lever 31 resists the biasing force of the spring 34 and moves to the seventh position around the rotation shaft 29.
Since the positional relationship is set so that it is pushed back in the direction of the arrow in the figure, it is eventually pressed against the capstan by the biasing force of the spring 34. Also,
The playback operator 2θ is locked at the suppressing operation position shown in FIG. 9, and its locking mechanism will be described later.

Here, the configuration of the tape recorder mechanism section will be explained. That is, as shown in FIG. 6 again, a tape running motor 43 is attached to the upper right portion of the main chassis 27 in the figure. Rotating shaft 4 of this motor 43
A pulley 432 having a small diameter is fitted into the pulley 31 . Also,
A flywheel 44 is rotatably supported at the lower right portion of the main chassis 270 in the figure, and the flywheel 44 and the pulley 432 are connected to each other through a belt 45 so that rotational force can be transmitted. The rotation axis of the upstream flywheel 44 is the capstan 46.

Furthermore, as shown in FIG. 10, the flywheel 44 is coaxially provided with a gear 47 having a small diameter.

On the other hand, substantially at the center of the main chassis 27, the pair of reel shafts 16 and 17 are rotatably supported. Of these, the reel shaft 16 which becomes the winding side during fast forwarding is connected to the main chassis 27 as shown in FIG.

It is slid downward in the figure against the urging force of 2. The locking member 50 is moved downward in the figure until its lower end in the figure abuts against the flange 481 of the bearing member 48. In this state, the tapered portion 5 of the locking member 50
02, the second engaging portion 75 of the switch lever 75
2 is pressed, the switch lever 75 is rotated counterclockwise in FIG. Therefore, the leaf switch 76 is turned on and the reel shaft 16 is locked at the suppressed position.

At this time, as the reel shaft 16 is suppressed,
The rotating shaft 16 also moves downward in the figure, and the gears 53 and 54 fitted on the rotating shaft 161 are also moved in the same direction. Therefore, the gear 54 separates from the gear 59, and the gear 53 becomes the gear 5.
It will mesh with 8. Therefore, the rotational force of the flywheel 44 in the counterclockwise direction in FIG.
．． 53 and the rotating shaft 161, the reel cap 5 is rotated at high speed counterclockwise in FIG. 6, and the tape is fast-forwarded.

It is also assumed that the rewind operator 22 is operated to suppress tape rewinding. Then, as shown in FIG. 13, the reel cap 64 of the reel shaft 17 is pressed downward in the figure, and as a result, the locking member 63 is pressed against the spring 6.
It is slid downward in the figure against the urging force of 5. The locking member 630 is moved downward in the figure until its lower end in the figure comes into contact with the mounting portion 621 of the bearing member 62. In this state, the tapered portion 6 of the locking member 63
32, the third engaging portion 75 of the switch lever 75
3 is pressed, the switch lever 75 is rotated counterclockwise in FIG.
do. For this reason, t! When the IJV leaf switch 76 is turned on, the reel shaft 17 is locked at the suppressed position. At this time, the lower end of the locking member 630 in the drawing presses the connecting portion 691 of the rewinding lever 69 downward in the drawing, so that the entire rewinding lever 69 is slid downward in the drawing. Therefore, the gears 66 and 70 are slid downward in the figure while being meshed, and at this time, the gear 70 is meshed with the gear 58. Also, the engaging portion 6 of the rewinding lever 69
92, the gear 54 is slid downward in the figure against the biasing force of the spring 56, so that the gear 54
He will be withdrawn from 9. Therefore, the rotational force of the flywheel 44 in the counterclockwise direction in FIG.
66 and the rotating shaft 17, the reel cap 64 is rotated at high speed clockwise in FIG. 6, and the tape is rewinded.

Next, the reward obtained by operating the stop operator 23 in the playback, fast-forwarding, and rewinding states will be explained. That is, in the playback, fast-forwarding, and rewinding states, the first drive section 39. Either of the lock members 5o, t; 3 is connected to the corresponding first to third retaining portions 7 of the lock lever 74.
It is locked by 4-743. To operate the stop operator 23 is to operate both the fast forward and rewind operators 21 and 22, as described above. Here, the fast forward and rewind operator 21.2
2, both reel shafts 16, 17 are slid downward in FIG. 11, for example. Therefore, regardless of whether the tape recorder is in any of the three operating states mentioned above, each locking member 5 of the reel shaft 16, 17
The second or third engaging portion 742° 743 of the lock lever 74 is pressed by one or both of the 0.63 taper portions 502° 632, and the lock lever 74 is rotated counterclockwise in FIG. Eventually, the lock will be released and it will be in a stopped state.

Here, when both reel shafts 16 and 17 are pressed as described above, the stop slider 80
4 is pressed by the tapered portion 632 of the locking member 63 of the reel shaft 17, so that it slides to the right in FIG. At this time, since the reel shaft 16 is also pressed, the tapered portion 502 (large diameter portion) of the locking member 50
The protruding piece 805 of the stop slider 80 comes into contact with it. That is, the stop slider 80 is sandwiched between the large diameter portions of the tapered portions 502, 632 of both the reel shafts 16, 17. For this reason, both reel shafts 16, 17 are restricted from being operated to a deeper position than if they were operated alone. The two locking members 50,
63 is the second and third retaining portion 742 of the lock lever 74
, 743 so that they are not locked together. Therefore, even if the stop operator 23 is operated, both reel shafts 16 and 17 are not locked at the operating position. In other words, the operating stroke of the stop operating element 23 is shorter than the stroke of operating the fast forward and rewind operating elements 21 and 22 alone.

The tape recorder described in this embodiment is equipped with an automatic stop mechanism that automatically stops the tape when it reaches the end during playback. To explain this with reference to FIG. 10, one end of a friction lever 82 is provided at the lower part of the gear 59 in FIG. When the friction lever 8
A long hole 82) is formed at the other end of 2, and a bottle 8 protruding from one end of the detection lever 83 is inserted into the long hole 821.
31 is loosely fitted. The detection lever 83 is rotatably supported by a shaft 84 protruding from the main chassis 27 at its substantially central portion. In addition, the detection lever 8
One side of the other end of the gear 3 is brought into contact with a side surface of a cam portion 85 provided on the gear 58 . Furthermore, two bins 832 and 833 are provided protruding from the other end of the detection lever 83. Of these, the pin 832 faces the second retaining portion 742 of the lock lever 74, and the other pin 833 is engageable with the curved operating wall 58 formed on the flat surface of the gear 58. There are 11 people.

In the tape town state described above, the flywheel 44 and gear 47 move in the counterclockwise h1 direction in FIG. This causes the gears 58 and 59 to rotate clockwise in FIG. Therefore, the friction lever 82 is biased clockwise in FIG. 6 by the rotational force of the gear 59, and the detection lever 83 is also moved clockwise in the figure about the shaft 84. At this time, since the other end of the detection lever 83 is in sliding contact with the cam portion 85, the detection lever 83 eventually performs a swinging motion around the support 84, and a stable soil condition is maintained. When the tape reaches the end in such soil conditions, the rotation of the reel shaft 16 is stopped, thereby causing the gears 54, 54,
The rotation of 59 is stopped. At this time, there is slippage between gears 58 and 59. Then, by stopping the rotation of the gear 59, the original vibration lever 82 and the detection lever 83 are
Situation power will no longer be granted. - Since the gear 58 continues to rotate, the cam part 85 also rotates, and the detection lens (
-83 is rotated counterclockwise in FIG. 6 about the shaft 84 by the length of the maximum diameter of the cam portion 85, and is stopped at that position. Then, due to the rotation of the gear 58, the outer part of the operating wall 58) detects and contacts the bin 833 of A2B, and along the curved shape of the operating wall 581, the bin 833 and the detection reno (-83) are moved from the above-mentioned stop position. is further rotated in the counterclockwise direction in FIG. The playback operation element 20 is rotated counterclockwise.Therefore, the playback operation element 20 is unlocked at the operation position, and an automatic stop is performed at this point.

FIG. 14 shows a state in which the pause operation member 86 is attached using one capstan insertion hole 13) of the tape cassette 13. That is, when the tape cassette 13 is installed in the tape cassette storage section 14,
The capstan 46 is inserted into one capstan insertion hole (not shown), and the other capstan insertion hole 1'31
The pose operation member 86 is inserted into the position. This pose operation member 86 is supported by the main chassis 27 so as to be slidable in the vertical direction in the figure, and is connected to a well-known button shoe mechanism at the bottom of the main chassis 27 in the figure, and is also engaged with the leaf switch 87. are combined.

Further, the cassette lid 12 is provided with a pause operator 88 similar to the fast forward, rewind, and stop operators 2 to 23 described above. When the pause operator 88 is pressed once, the pose operating member 86 is pushed down in the figure and locked at that position. At this time, the leaf switch 87 is turned off, power supply to the motor 43 is stopped, and tape running is stopped. In this state, when the P+ pause operator 88 is pressed, the pause operation member is unlocked, the leaf switch 87 returns to its original on state, and tape running is resumed.

Therefore, according to the configuration as in the above embodiment, first,
Since various types of controls are provided on the cassette cap 12 itself, the controls can be large and spacious, making it extremely easy to operate, and also preventing tape recorders from becoming smaller. do not have. Here, each of the above-mentioned operators may be provided by integrally molding with the cassette lid 12. In this case, for example, it is effective to make the part of the cassette lid 12 that is the operator thin and elastic so that it can be slightly suppressed.

In addition, since the cassette lid 12 is provided so that the boundary between the operating section 18 and the transparent section 19 straddles the reel shaft 16, 17, it is easy to visually check the tape running state and the remaining amount of tape from the outside. It is something that can be done.

Furthermore, since the reel shafts 16 and 17 are used as operating parts for operating in the axial direction, the structure is organic and free of waste.
All operations can be carried out reliably. Furthermore, since the reel shafts 16 and 17 on the winding side during fast forwarding and rewinding are used for fast forwarding and rewinding operations, erroneous operations can be prevented and operability can be further improved.

Furthermore, the reel shaft 16.17 includes a reel cap 51.64 for rotation, and locking members 50, 63 for turning the lock and leaf switch 76 on and off.
Since they are provided coaxially and separately, unnecessary side pressure such as spring urging force from the tape recorder mechanism side is not applied to the reel caps 51, 64, and stable running of the tape is not prevented.

Here, the means for locking the reel shaft 16, 17 at the operating position and turning on the leaf switch 76 is as follows.
This can also be done as shown in FIG. That is, in this case, to explain the reel shaft 16, the rotation shaft 161 of the reel shaft 16 is supported by a member 89 in a bearing in which the rotating shaft 161 is oiled in the main chassis 27 so as to be slidable and rotatable in the vertical direction in the figure.

A locking member 9 is located at the bottom of this rotating shaft 161 in the figure.
0 is engaged. The other end of the locking member 90 is rotatably supported and biased counterclockwise in the figure by a torsion spring 91. Additionally, a tapered portion 90 is provided at one end of the locking member 90 as shown in the figure.
1 is formed.

Then, when the reel shaft 16 is suppressed downward in the figure,
In conjunction with this, the lock member 90 is rotated clockwise in the figure, and at this time, the lock lever 74 and the switch lever 7
5 is pressed and rotated by the taper portion 901. Also, when locked, the lock lever 74
is engaged with the rotating upper end of the locking member 90, and the reel shaft 1
6 is locked in the operating position.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and can be implemented with various modifications without departing from the gist thereof.

That is, although the above embodiment has been described with respect to a playback-only tape recorder, the present invention is of course applicable not only to playback-only tape recorders but also to tape recorders that perform recording and playback. In other words, the tape recorder referred to here may be one that can perform both recording and playback, or one that can only be used for playback.

Therefore, as described in detail above, according to the present invention, it is possible to provide an extremely good tape recorder device that has a simple configuration, improves operability, and effectively promotes miniaturization.
