この考案は、カセツトテープのハウジングをな
すカセツトハーフに設けられた表裏識別用被検出
部材を検出する表裏検出装置を有するカセツトテ
ープレコーダに関する。DETAILED DESCRIPTION OF THE INVENTION This invention relates to a cassette tape recorder having a front/back detection device for detecting a detection member for front/back identification provided on a cassette half constituting a housing of a cassette tape.
カセツトテープレコーダの操作性を向上するた
め、テープデツキに装着されたカセツトテープの
表裏(A面、B面又は1面、2面)を検出して表
示したり、テープ駆動系の動作を自動的に切換え
たりすることが試みられている。 In order to improve the operability of the cassette tape recorder, it is possible to detect and display the front and back sides (A side, B side, 1st side, 2nd side) of the cassette tape loaded in the tape deck, and to automatically control the operation of the tape drive system. Attempts are being made to switch.
そのため、カセツトハーフの一方の面にのみ設
けられ、他方の面には存在しない凹部や着磁板の
ような被検出部材を、シヤーシの一部に設けた表
裏検出装置で検出してその表裏を判別する方法が
提案されていた。 Therefore, detecting members such as recesses and magnetized plates that are provided only on one side of the cassette half and not on the other side are detected by a front/back detection device installed in a part of the chassis to detect the front and back sides. A method for determining this has been proposed.
しかしながら、このような表裏検出装置では、
カセツトテープがカセツトテープレコーダに完全
に装着された状態でなければ検出は不可能であつ
た。 However, in such a front/back detection device,
Detection was impossible unless the cassette tape was completely attached to the cassette tape recorder.
また、カセツト装着部の蓋を兼ねたカセツトホ
ルダにカセツトテープを予め挿入して回動するよ

の位置関係が、カセツトテープをホルダに挿入し
た時とテープデツキの動作面上に装着時とで若干
異なるため、検出精度が悪く、時として表裏を誤
検出するおそれがあつた。 In addition, in a cassette tape recorder in which a cassette tape is inserted in advance into a cassette holder which also serves as a lid of a cassette loading section so that the cassette tape can be easily installed, if the cassette holder is provided with a front/back detection device, the cassette tape can be rotated. It is possible to detect the front and back sides of the tape before it is completely installed, but the positional relationship between the cassette holder, which is the cassette tape installation part, and the cassette tape is different when the cassette tape is inserted into the holder and when it is installed on the operating surface of the tape deck. Because of the slight difference, the detection accuracy was poor, and there was a risk of erroneously detecting the front and back sides at times.
この考案は上記の点に鑑みてなされたもので、
カセツトテープ装着部と装着されたカセツトテー
プとの相対位置関係が多少変化しても、カセツト
テープの被検出面と検出装置との相対位置関係が
常に一定に保たれるようにして、高精度に表裏検
出をなし得るようにすることを目的とする。 This idea was made in view of the above points,
Even if the relative positional relationship between the cassette tape loading section and the loaded cassette tape changes slightly, the relative positional relationship between the detected surface of the cassette tape and the detection device is always kept constant, achieving high accuracy. The purpose is to enable detection of front and back sides.

材に取付けることによつて、上記の目的を達成す
るものである。 Therefore, in the cassette tape recorder according to the present invention, a detection device for detecting the detected member provided on the cassette half is attached to the cassette tape mounting section, and the detection device is attached to the cassette tape mounting section so that the detecting device detects the detected member provided on the cassette half, and the detecting device is attached to the cassette tape mounting section so as to be placed in contact with the detected surface of the cassette tape mounted on the mounting section. The above object is achieved by attaching it to a movable member that is urged into contact with the movable member.
以下、添付図面を参照してこの考案の実施例を
説明する。 Embodiments of this invention will be described below with reference to the accompanying drawings.

る。 Figure 1 shows the first embodiment of this invention.
The lower edge of the rotary cassette holder 1, which constitutes a cassette tape mounting part consisting of a lid part 1a and a detection member mounting part 1b, is pivotally connected to the main body of a cassette tape deck (not shown) by a shaft 2, and the detection member mounting part 1b is Spring 3
A movable member 4 is attached via a and 3b, two rollers 5a and 5b are rotatably provided on the movable member 4, and the roller 5a is attached to the detection surface 10a of the cassette tape 10 mounted on the cassette holder. ,5b
It is biased by springs 3a and 3b so that they come into contact with each other.
そして、この可動部材4のローラ5a,5b間
に検出装置6が取付けられている。 A detection device 6 is attached between rollers 5a and 5b of this movable member 4.
一方、カセツトテープ10の表裏何れかの被検

アレンスピン(図示しない)にばね3a,3bで
押付けられ、カセツトテープ10の位置が決定さ
れる。 When the cassette holder 1 is rotated from this state and the cassette tape 10 is attached to the performance surface of the tape deck body, the cassette tape 10 is completely attached to the back surface 1c of the cassette holder lid 1a.
The position of the cassette tape 10 is determined by being pressed by springs 3a and 3b against a reference pin (not shown) that is provided on the performance surface and slightly separated from the cassette tape 10.
この間、検出装置6と被検出部材11の間隙は
常に一定に保たれ、カセツトテープ10とカセツ
トホルダ1の関係位置の変動による誤検出が防止
される。 During this time, the gap between the detection device 6 and the member to be detected 11 is always kept constant, and erroneous detection due to fluctuations in the relative position between the cassette tape 10 and the cassette holder 1 is prevented.
次に、第2図に示すものは、上記第1実施例の
一部を変更したこの考案の第2実施例を示し、第
1実施例でカセツトテープを挿入した時、可動部
材4が図で上下方向に変位し易い点を改良したも
のである。 Next, FIG. 2 shows a second embodiment of this invention, which is a partial modification of the first embodiment, and when the cassette tape is inserted in the first embodiment, the movable member 4 moves as shown in the figure. This is an improvement in that it is easily displaced in the vertical direction.

5が、装着されたカセツトテープ10の被検出面
10aに当接するようになつている。 Lever-shaped movable member 14 in this embodiment
The cassette tape 10 is equipped with a roller 5 whose one end is pivotally connected to the detection member attachment part 1b of the cassette holder 1 by a shaft 17, and which is rotatably provided by a spring 3 to give it a left-handed rotation as shown in the figure. The detection target surface 10a is brought into contact with the detection target surface 10a.

る。 Therefore, the detection surface 10a with the recess 10c
When facing the leaf switch 16, the roller 5
fits into the recess 10c, the movable member 14 rotates to the left as shown in the figure, and the protrusion 16 of the leaf switch 16
a is pushed by the detection surface 10a, and the movable contact piece 16b
contacts the fixed contact piece 16c and the switch is closed.
一方、凹部10cのない被検出面10bがロー
ラ5に対向した時は、可動部材14がばね3に抗

る。 On the other hand, when the detection surface 10b without the recess 10c faces the roller 5, the movable member 14 is rotated to the right against the spring 3, and the leaf switch 16 is opened.
このリーフスイツチ16の閉又は開状態によ
り、装着されたカセツトテープの表裏を検出する
ことができる。 Depending on the closed or open state of the leaf switch 16, it is possible to detect the front and back sides of the loaded cassette tape.
この被検出部材としての凹部10cは、フイリ
ツプス規格のカセツトテープの大部分には、カセ
ツトハーフを締付けるねじの頭部埋没用の穴が一
方のカセツトハーフにのみ設けられているので、
それを利用することができる。 This recessed part 10c as a member to be detected is because most of the cassette tapes of the Philips standard have a hole in only one cassette half for embedding the head of the screw for tightening the cassette half.
You can take advantage of it.
なお、カセツトテープ10に設けられる被検出
部材が凸部であつても同様にして検出することが
でき、また、導通板の場合は検出装置として導通
ピンを用いればよい。 Note that even if the detected member provided on the cassette tape 10 is a convex portion, it can be detected in the same manner, and in the case of a conductive plate, a conductive pin may be used as the detection device.
