で、カセツトテーププレーヤ自体の製造コストを
上昇させる原因となつている。(Prior Art and its Problems) The cassette tape insertion slot of a cassette tape player is sometimes provided with a door to prevent the cassette tape being played from being seen from the outside, or to block the inside after the cassette tape is ejected. The door is opened when the cassette is inserted, closed during playback, and opened again after the playback is finished, ie, when the cassette tape is ejected, to eject the cassette tape.
A dedicated drive motor is usually used as a drive source for opening and closing such doors. It is a so-called electromechanical type. This type does not have a mechanically complex length and requires a separate dedicated motor, which causes an increase in the manufacturing cost of the cassette tape player itself.
（問題点を解決するための手段）
本考案は上記問題点に鑑み案出されたもので、
イジエクトレバーの前後動によつて先端部を上下
動させる開閉レバーにより、カセツトテープ挿入
口に設けた扉を開閉させるものである。(Means for solving the problems) This invention was devised in view of the above problems.
The door provided in the cassette tape insertion opening is opened and closed by an opening/closing lever whose tip part is moved up and down by the back and forth movement of the eject lever.

It is brought into contact with the lower surface of the pin. As the eject lever moves back and forth, the guide pin in the cam groove moves up and down, and the tip of the opening/closing lever pushes up the bottom surface of the pin provided on the side of the opening/closing door, centering on the support shaft, thereby opening/closing the door. It opens the door inward.
（実施例）
以下図面に基づき本考案の扉開閉装置を詳細に
説明する。(Example) The door opening/closing device of the present invention will be explained in detail below based on the drawings.
第１図はカセツトテーププレーヤの機器本体１

れている。 This device main body 1 has a built-in cassette tape player as will be described later, and is provided with a nose, a so-called operating section 2, on the front surface thereof. The operation section 2 is provided with a volume dial and various selection switches, and also has a display section made of a liquid crystal or the like for displaying modes. In order to load a cassette tape T into a player built into the device main body 1, a tape insertion slot 3 is formed approximately in the center of the operating section 2. Further, an opening/closing door 4 for opening and closing the tape insertion slot 3 is provided. As will be described later, the opening/closing door 4 itself is always urged in the closing direction by a spring (not shown).
第２図は機器本体１内に内蔵されたカセツトテ

When pushed in, the insertion/removal lever 53 and the ejection lever 54 move to automatically draw in the cassette tape T, and the cassette tape T is loaded into the cassette holder 52 provided between the side surfaces 51 and 51 of the main body. Next, the holder is pushed down to the performance position via the holder pressing plate 55.

扉４の側部４１中央より上方で且つ扉ヒンジｈは
ピンPbよりも更に上方に設けられている。 A door opening/closing device 6 is provided on either one of the main body side plates 51, 51. The door opening/closing device 6 is the third
As shown in the schematic side view of the figure, the approximate center of the opening/closing lever 7 is pivoted to the main body side plate 51 via a support shaft 8, and a cam groove C is formed in the rear end 72 of the opening/closing lever 7.
A guide pin Pa provided upright on the eject lever 54 is slidably engaged in the cam groove C. The lower side C1 of the cam groove C has a protruding center,
The front recess C 2 and the rear recess C 3 form a substantially M-shape. On the other hand, the tip 73 of the opening/closing lever 7 is locked in contact with the lower surface of a pin Pb provided on the side of the opening/closing door 4. This pin Pb is provided below the door hinge h provided above the side portion 41 of the opening/closing door 4. In other words, the pin Pb is provided above the center of the side portion 41 of the opening/closing door 4, and the door hinge h is provided further above the pin Pb.
又開閉扉４はヒンジｈ等に介装されたコイルバ
ネ（図示せず）により常に外方、すなわち閉方向
に付勢された状態となつている。 Further, the opening/closing door 4 is always urged outward, that is, in the closing direction, by a coil spring (not shown) interposed in the hinge h or the like.

中心にして内方へ回動する構造となつている。 Moreover, the switch of the operation section 2 is a so-called touch type, and the eject lever 54 itself is not designed to extend outward from the operation section 2. Therefore, if the pin Pb is pushed up with the tip 73, the opening/closing door 4 is moved from the door hinge. It has a structure that rotates inward around h.
斯かる扉開閉装置６における開閉動作を第２図
乃至第５図により説明する。 The opening/closing operation of the door opening/closing device 6 will be explained with reference to FIGS. 2 to 5.

照）。 First, when the cassette tape T is pushed in, the cassette tape T is automatically drawn into the cassette holder 52 via the insertion/removal lever 53 or the like. When the cassette tape T is pulled in to the back, the ejector lever 54 moves toward the tape insertion slot 3, and is accordingly lowered to the playing position by the holder pressing plate 55 (see FIG. 2). At this time, the guide pin
Pa is fitted into the front recess C 2 of the cam groove C, and the lever tip 73 is lowered by the biasing force of the coil spring provided in the door 4 to close the door 4 (see FIG. 3).

参照）。 On the other hand, when pressing the eject button (not shown) at the end of the performance,
The cassette holder 52 is pressed by the holder pressing plate 55.
As the lever 54 rises, the eject lever 54 moves back in the opposite direction to that described above. Therefore guide pin
Pa slides along the lower side C1 of the cam groove C and rises to the protrusion, and pushes up the lever tip 73 again to open the opening/closing door 4 inward (see Fig. 4). Then, the cassette tape T is pushed out to the cassette insertion slot 3 by the insertion/removal lever 53 or the like and is ejected. As the cassette tape T is ejected, the guide pin Pa reaches the rear concave portion C3 , the push-up of the lever tip 73 is released, and the opening/closing door 4 is rotated outward by the biasing force of the coil spring, that is, closed. (See Figure 5).
以上の様に本考案の扉開閉装置ではカセツトテ
ープの排出時に開閉扉が自動的に開かれ、又演奏
時および排出完了時にはカセツト挿入口が開閉扉
により完全に閉ざされた状態となる。 As described above, in the door opening/closing device of the present invention, the opening/closing door is automatically opened when the cassette tape is ejected, and the cassette insertion slot is completely closed by the opening/closing door during playing and when ejection is completed.
尚上記実施例では、開閉レバー７の後端部７２

A cam groove C is provided in the cam groove C, and a guide pin Pa provided upright on the eject lever 54 is engaged with the cam groove C.
In contrast to the above, a guide pin Pa may be provided upright on the rear end portion 72, and a cam groove C may be provided on the eject lever 54, so that the two may be slidably engaged.

扉を開かせることが可能となる。(Effects) As described above, the door opening/closing device for a cassette tape player of the present invention moves the tip of the opening/closing lever up and down by moving the eject lever back and forth, and the tip of this lever is provided at the tip of the opening/closing door. The door opens and closes by pressing the pin. Therefore, it is possible to accurately open the opening/closing door in harmony with the timing when the cassette tape is ejected.
更に又イジエクトレバーの前後進によつて開閉
扉を開かせるので、特別な駆動モータを要さず、
製造コストも大幅に低減することが可能となる。 Furthermore, since the door is opened by moving the escape lever back and forth, no special drive motor is required.
Manufacturing costs can also be significantly reduced.
