Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to a cassette tape recorder device that is oriented toward miniaturization. [Technical background of the invention and its problems] In recent years, cassette tape recorders are small and lightweight, making them suitable for carrying, and two-way stereo type devices have become popular, especially for playback using headphones. For example, it is possible to play a tape while walking while wearing headphones. In the case of such portable cassette tape recorder devices exclusively for headphones, devices that are approximately the same size as the cassette case housing the tape cassette are currently appearing. By the way, when cassette tape recorder devices are miniaturized, it is particularly required to improve the shape and arrangement of the respective controls for putting the cassette tape recorder device into various operating states such as playback, rewinding, etc., and into stop states. The goal is to improve operability, make it easier to use, and make it more convenient to carry. However, the compact tape recorder devices that have been realized to date do not necessarily satisfy the above-mentioned requirements and have many various disadvantages. For example, it is too large to be carried by storing it in the chest pocket of a dress shirt or the like. For this reason, for example, the user used a special holster and carried the device by attaching it to the waist. However, with a simple structure that is organic and has no waste,
In addition, there is a demand for improved operability and further miniaturization so that it can be stored in the chest pocket of a dress shirt, for example. [Purpose of the invention] This invention was made in view of the above circumstances, and the purpose is to provide an extremely good cassette tape recorder device that has a simple configuration and can effectively promote miniaturization. . [Summary of the invention] In other words, this invention consists of a tape cassette storage part into which a tape cassette can be loaded while being exposed from the case, a lid body supported to be openable and closable with respect to the tape cassette storage part, and this lid body. The present invention is characterized in that it includes an operator provided in the tape cassette storage section and having a lock portion that can be engaged with the head of the reel shaft of the tape cassette storage section. [Embodiment of the invention] Hereinafter, an embodiment of the invention will be described in detail with reference to the drawings. FIG. 1 shows the appearance of a cassette tape recorder to which this invention is applied. That is, 11 is a substantially box-shaped cabinet formed smaller than the outer circumference of the tape cassette to be loaded, and one flat surface of this cabinet 11 serves as a cassette lid 12 as it is. Here, the cassette lid 12 is formed into a substantially L-shaped side surface so that the outer circumferential portion of the tape cassette to be loaded can protrude. It is supported so that it can be rotated to open and close. Further, the cassette lid 12 is lightly locked in the open position to prevent it from wobbling, and is securely locked in the closed position by a locking mechanism to be described later.
Furthermore, the cassette lid 12 has a cassette holder 13, the details of which will be described later.The cassette holder 13 is linked to the opening/closing operation of the cassette lid 12, and is capable of holding a loaded tape cassette. be. The cabinet 11 includes a storage section 14 for storing a predetermined portion of the tape cassette with the cassette lid 12 closed, and a tape recorder mechanism section (not shown) including a drive mechanism to be described later.

Furthermore, a lock operator 17 and a rewind operator 18, which will be described later, are supported on the cassette lid 12 at positions facing the reel shafts 15 and 16 on the winding side during tape playback and rewinding. . Of these, the lock operator 17 is installed so that it can be operated in the direction of arrow C, and in conjunction with this operation, the lock mechanism, which will be described in detail later, is operated to open the cassette lid 12. be. On the other hand, the rewind operator 18 is connected to the reel shaft 16, which will be described later.
It is installed so that it can be operated by pressing in the direction. Further, in the cassette lid 12, a playback operator 19 and a stopper operator 20 are provided near the periphery of one side that does not face the flat surface of the tape cassette to be loaded, so that they can be operated by pressing substantially perpendicularly to the surface of the cassette lid 12. is set up. Further, at one end of the cassette lid 12 opposite to the cassette holder 13, the cassette lid 1 is attached.
A front door 21 is provided to reinforce the front door 2. The front door 21 has a substantially plate-like shape, and has notches 2 in the middle corresponding to the reel shafts 15 and 16.

A torsion spring 23 is interposed between the front door 21 and the cassette lid 12, and the biasing force of the torsion spring 23 causes the front door 21 to move approximately perpendicularly to the cassette lid 12. It is located. Therefore, when the cassette lid 12 is closed to the cabinet 11, the front door 21 is interposed approximately perpendicularly between one end of the cabinet 11 and one end of the cassette lid 12. , to reinforce the cassette lid 12. That is, when loading a tape cassette into the above-mentioned cassette tape recorder device, first, as shown in FIG. Insert it facing the holder 13. At this time, the front door 21 supported by the cassette lid 12 is moved toward the arrow E by the tape cassette 24 against the spring force of the torsion spring 23.
The tape cassette 24 is rotated in the direction shown in FIG. Here, the reel hub parts 25 and 26 of the tape cassette 24 are located in the notch 22 of the front door 21, and when the cassette lid 12 is closed, the reel shafts 15 and 16 are removed from the notch 22.
Each is made to stand out. Next, as shown in FIG.
When the tape cassette 24 is closed, a part of the outer circumference excluding the exposed tape part protrudes from the cabinet 11, and the tape cassette 24 becomes the so-called cabinet 1.
1 and the cassette lid 12 are held together. FIG. 4 shows details of the loading state of the tape cassette 24. That is, on the inner surface of the cassette lid 12, a substantially plate-shaped spring member 27 for holding the tape cassette is provided corresponding to the tape cassette 24. This spring member 27 has its base end locked with the locking part 28 of the cassette lid 12, and its middle part locked with the protrusion 28 of the cassette lid 12.

It presses in the 5th and 16th directions and in the direction of the reproduction head, which will be described in detail later. Therefore, the loaded tape cassette 24 is securely held against the cabinet 11 by the spring member 27. FIG. 5 shows the cassette tape recorder device loaded with a tuner pack 33 instead of the tape cassette 24 (see FIG. 3). That is, the cassette tape recorder device is not only capable of simply playing back tapes, but also can receive radio broadcasts by using a tuner pack. This uses a tuner pack 33 in which a tuner circuit (not shown) for receiving, tuning, detecting and amplifying radio waves is housed in a casing having approximately the same diameter as the cabinet 11, and the tuner pack 33 is connected to the tape cassette 24. (See Figure 3) instead of Cabinet 1.
This is done by loading it into 1. An operation section 34 having a display section 341 provided on one end side of the tuner pack 33
When a desired broadcasting station is selected by operating the tuning dial 35, the received radio waves are detected and amplified, and then introduced into the main amplifier circuit in the cassette tape recorder device via a connection terminal (not shown). This is played back by a headphone (not shown), and the radio broadcast is received here. At this time, with the cassette lid 12 closed, the operating section 34 is exposed between the cassette lid 12 and the cabinet 11,
This operation can be performed without opening the cassette lid 12. In this way, the tuner pack 33 has an operating section 34 that can be operated externally at one end and is shaped approximately the same as the cabinet 11, so that when loaded in a cassette tape recorder device, the operating section 34 is connected to the cabinet 11. 11 and the cassette lid 12 so that it can be operated externally. Therefore, the above-mentioned cassette tape recorder apparatus eliminates the need to provide a special operating section for operating the tuner pack 33, and the structure is simplified and can be made smaller.

It is. Furthermore, a switch slider 95 is arranged on the lower surface of the lock plate 89. Then, in response to the operation of the regeneration operator 19, a motor power switch (not shown), which is operated against the spring force of the spring 96 in substantially the same way as the lock plate 89, is turned on, and the motor 39 (see FIG. 6) is turned on. is rotated in a predetermined state. Here, the switch slider 95 is connected to the lock plate 8 described above.
When the stop operator 20 is operated in the same manner as in 9,
The lock is released and the device returns to its original position. In the above configuration, when the playback operator 19 is operated to play back a tape, the playback head 42 and the pinch roller 43 are moved, and the playback head 42 is brought into contact with the tape, and , the pinch roller 43 is pressed against the capstan 38 via the tape. At this time, in conjunction with the operation of the playback operator 19, the lock plate 89 and the switch slider 95 move against the spring force of the springs 94 and 96 as indicated by the arrow M in FIG.
The playback operation element 19 is locked at the operation position by the lock plate 89 and the switch slider 95. At this time, the motor 39 (see FIG. 6) is rotationally driven by the switch slider 95 turning on the motor power switch. Then, the flywheel 59 is rotationally driven by the motor 39 as shown in FIG. 8a. Here, this rotational force is applied to the fourth and fifth gears 6 by a gear 66 rotating together with the flywheel 59.

The reel cap 72 on the rewinding side is driven to rotate at a higher speed than in the tape playback state by being sequentially transmitted to the ninth gear 82, the tenth gear 83, and the sixth gear 75. , the tape is rewound. Here, when performing fast forwarding of the tape, by operating a fast forwarding operator (not shown), the governor circuit (not shown) is electrically disconnected from the motor 39 ( (see FIG. 6) is rotated at high speed, and the reel cap 52 on the reproduction side is rotated at a higher speed than in the reproduction state to perform fast forward running of the tape. In this way, the reel hub portion 25 for inserting the reel shaft formed in the thickness direction of the tape cassette 24,
Of the reel shafts 15 and 16 of the cassette tape recorder device, which are inserted through the reel shaft 26 (see FIG. 2), the reel shaft 16, which is on the winding side in the rewinding state, is used as an operating member for operating the reel shaft 16 in the axial direction. As a result, there is no waste in the configuration, and organic and reliable operation can be achieved. In addition, drive switching for tape rewinding is
A drive switching mechanism is provided for the reel shafts 15 and 16, and this drive switching mechanism is configured to respond in conjunction with the pressing operation of the reel shaft 16 on the rewinding side. Therefore, the configuration is simplified, space is available, and downsizing is easily achieved. By the way, FIG. 10 shows details of the locking mechanism for locking the cassette lid 12 in the closed position. That is, the reel shaft 15 on the playback side has the aforementioned locking member 55 at the tip of the shaft 45.
A substantially rectangular through hole 97 is provided in the cassette lid 12 facing the lock member 55.
is formed. The aforementioned lock operator 17 is disposed in the through hole 97 so as to be slidable in the directions of arrows C and D. And this lock operator 17
A locking portion 98 is provided on the lower surface of the locking member 55 so as to protrude from the locking groove 57 of the locking member 55. Here, one end of a coiled spring 99 is attached to one end of the lock operating element 17,
The other end of this spring 99 is attached to the cassette lid 1.
It is engaged with a step 971 formed at one end of the through hole 97 of No. 2. For this reason, the lock operator 1
7 is always urged in the direction of arrow D against the cassette lid 12 by the spring 99. That is, when opening the cassette lid 12 from the closed position relative to the cabinet 11 (see FIG. 2), first slide the lock operator 17 in the direction of arrow C against the spring force of the spring 99. When the lock member 98 of the lock operator 17 is
It is moved in the direction of arrow C. Therefore, the cassette lid 12 is attached to the lock portion 98 of the lock operator 17.
When the locking groove 57 of the locking member 55 is released, the opening state can be established. Here, for example, the cassette lid 12 may be provided with a spring member so as to apply a spring force in the opening direction, and the cassette lid 12 may be configured to be in an open state with respect to the cabinet 11 by the spring force of the spring member, thereby obtaining a more effective effect. This is what you get. Also, attach the cassette lid 12 to the cabinet 11.
When the cassette lid 12 is to be locked from the open position to the closed position (see FIG. 1), the cassette lid 12 is rotated to the closed position. Then, as shown in FIG. 10, the lock portion 98 of the lock operator 17 is moved along the inclined portion 561 of the lock member 55 of the reel shaft 15 and is locked in the lock groove 57. The cassette lid 12 is locked with respect to the cabinet 11 in the closed position (see FIG. 1). In this way, the locking member 55 provided on the reel shaft 15 is directly engaged with the locking portion 98 of the locking operator 17, so that the cassette lid 12 is locked in the closed position. Therefore, the cassette tape recorder device can be simplified in its configuration and downsized. In the above embodiment, the size of the cabinet 11 of the cassette tape recorder device is made smaller than the outer periphery of the tape cassette 24 so that the outer periphery of the tape cassette 24 protrudes, but the present invention is not limited to this. It is also effective to configure the tape cassette 24 to have substantially the same size and shape as the tape cassette 24 so that at least one end surface of the tape cassette 24 is exposed when the tape cassette 24 is engaged. It goes without saying that this invention can be modified in various other ways without departing from its gist. [Effects of the invention] As described above, according to this invention, it is possible to provide an extremely good cassette tape recorder device that has a simple configuration and can effectively promote downsizing.
