Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a tape recorder, and particularly to a front-loading type video tape recorder (VTR) in which the operation buttons are exposed and retracted.

(b) Prior art In order to effectively utilize the space on the top of the VTR in home VTRs, a so-called front loading method is used in which a cassette tape is inserted from the front of the VTR and installed inside the VTR. .
With this front loading method, when the cassette tape is inserted into the cassette insertion slot, which normally has a door that can be opened and closed, and held in the cassette holder, the cassette holder automatically moves to load the cassette tape.
Pull into the VTR. After the cassette tape has been drawn in by a predetermined amount, it is mounted on a reel stand within the VTR and the tape is loaded. When the cassette tape installation is completed, the opening/closing door returns to the closed state to close the cassette insertion slot. When the cassette tape is taken out, the opening/closing door is opened again to allow the cassette tape to be ejected.

By the way, in recent electrical equipment, it has been implemented to simplify the entire surface of the electrical equipment and increase its design effect by making the operation buttons that are not used frequently so that they can be stored in panels that can be opened and closed. There is. By performing these steps on the VTR,
If the operation buttons of the VTR were made retractable, the user would have to attach the VTR cassette and expose the operation buttons when operating the VTR, which was troublesome.

(c) Purpose of the invention The present invention has been made in view of the above points, and is a front-loading method that allows the operation section provided with operation buttons etc. to be conveniently stored and exposed.
It provides VTR etc.

(d) Structure of the invention This invention is a front-loading type VTR.
This VTR is equipped with a means for exposing and storing an operating section in conjunction with a cassette holder that moves the cassette tape to a predetermined position and to an ejecting position.

(E) Embodiment An embodiment of the present invention will be described with reference to FIGS. 1 to 7. In Figures 1 to 7, 1 is
VTR, 2 is a cassette insertion slot provided with an opening/closing door 3; 4 is an operating section consisting of push buttons 5 for operation, to which a marking plate for mode display is glued;
Reference numeral 6 denotes a rotating part in which the operation part 4 and a switch board part (not shown) are incorporated; 7 a cassette tape; 8 an eject button for ejecting the cassette tape 7 from the VTR 1; 9 a cassette A cassette holder for holding the tape 7, 10 a loading motor for moving the cassette holder 9, 11 and 12 a cassette insertion switch and a cassette installation detection switch, 13 a reel stand, 14
1 is a rotating shaft of the rotating part 6, 15 is a gear part provided on one side of the rotating part 6, 16, 17, 18, 1
Numeral 9 is a gear for transmitting the rotation of the worm gear 20 rotated by the motor 10 to the gear section 15, and a gear for exposing and storing the operating section 4 in conjunction with the loading of the cassette tape 7. forming means. Furthermore, gear 16 and gear 1
7 are connected via a slip mechanism using a felt plate 21. Further, the gear 18 and the gear 19 are provided integrally. Reference numeral 22 designates a leaf spring that presses and biases the gear 16 against the gear 17 so that the gears 16 and 17 are properly coupled, 23 designates a chassis frame, and 24 and 25 designate shafts.

The operation of the above-mentioned VTR 1 will be explained. first,
Insert cassette tape 7 into cassette insertion slot 2 of VTR 1.
When the cassette tape 7 is inserted further, the cassette insertion switch 11 attached to the cassette holder 9 is pushed on. Therefore, the loading motor 10 rotates to move the cassette holder 9 to the mounting position (see arrow A in FIG. 4). When the cassette holder 9 is moved to a predetermined position, the cassette holder 9 turns on the switch 12 to stop the loading motor 10 from rotating. Since such a front loading mechanism is described in detail in, for example, Japanese Patent Application No. 57-45433, the specific mechanism is omitted from the drawings of the present application to simplify the explanation. By the way, during the loading, the rotation of the motor 10 is transmitted to the cassette holder 9 via the gears 20, 19 and the shaft 24, and not only moves the cassette holder 9, but also moves the cassette holder 9 through the gears 20, 19 and the shaft 24.
7 and 16 to the gear section 15 and the rotating section 6
rotates around the rotating shafts 14, 14. Therefore, as shown in FIG. 2, FIG. 3, or FIG. 5, the operating section 5 is exposed on the outer surface of the VTR 1, and the push button 5 can be operated. Further, when the inject button 8 is pressed when the cassette tape 7 is ejected, the motor 10 rotates in the opposite direction and the cassette holder 9 moves in the opposite direction to that when it is attached. For this reason, gears 20, 19,
18, 17, and 16 also rotate in the opposite direction, so the gear portion 15 rotates in the direction in which the operating portion 4 is accommodated.

As described above, in this embodiment, the operating section 4 is exposed and retracted in conjunction with the mounting and ejection of the cassette tape 7, so when the cassette tape 7 is not mounted, the operating section 4 is retracted and the VTR 1 The front surface of the device is simplified to improve the design effect, and the operation for exposing and retracting the operating section 4 is simple and does not require a separate operation. In addition, since a slip mechanism is provided by the felt plate 21, the operation section 4
When the rotating part 6 receives a force in the direction of housing the operating part 4, such as when exposing the operating part 4, the gears 15, 16, 1
This is useful because it can prevent damage to parts 7, 18, 19, and 20.

In addition, in the above embodiment, the gear portion 15 is a spur gear, but the present invention is not limited to this.
For example, as shown in FIG. 8, the gear portion 15' may be a rack so that the operating portion 4 slides in conjunction with the loading of the cassette tape (in the direction of arrow B in FIG. 8).

(f) Effects of the invention As described above, according to the invention, the front face of the tape recorder is simplified by storing the operation part when the cassette tape is not installed, and the operation part is exposed when the cassette tape is installed so that the operation part of the tape recorder can be opened. In a tape recorder that can be operated, the exposure and storage of the operation section are automatically performed in conjunction with the loading of the cassette tape, so that no separate operation is required to expose and store the operation section. It is very useful.

Claims (1)

[Claim for Utility Model Registration] When a cassette tape is installed, when the detection means detects that the cassette tape is inserted from the cassette insertion slot, the cassette holder holding the cassette tape is moved to the playing position of the cassette tape by the loading motor. In the tape recorder, the loading motor automatically moves the cassette holder to a cassette ejecting position by operating an eject button when the cassette tape is ejected, In conjunction with the movement of the cassette holder, the loading motor exposes the operating section to the outside of the tape recorder, and in conjunction with the movement of the cassette holder during ejection, the loading motor causes the operation section to be exposed inside the tape recorder. A tape recorder comprising means for storing the tape recorder.
