本考案は検出装置、特にカセツトテープレコー
ダにおいてカセツトテープのREC孔、テープ種
類判別孔を検出する装置の改良に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a detection device, particularly a device for detecting REC holes and tape type discrimination holes of a cassette tape in a cassette tape recorder.
周知の如く通常のカセツトテープでは録音後に
誤録音爪を折つてしまうと、その跡が孔になる。
カセツトテープレコーダに於てこの孔の有無を、
例えばスイツチによつて検出し、孔のあるときは
録音できないようにしている。 As is well known, if the recording tab of a normal cassette tape is accidentally broken after recording, the hole will become a hole.
Check whether a cassette tape recorder has a lever hole or not.
For example, it is detected by a switch, and if there is a hole, recording is not possible.
またカセツトテープの種類に応じて、録音又は

上記種類を示す孔を設け、同様にスイツチ等でこ
の孔の有無を検出する。 Further, in order to automatically switch the recording or playback characteristics depending on the type of cassette tape, a hole indicating the type is provided in the cassette, and the presence or absence of this hole is similarly detected by a switch or the like.
このようにスイツチを用いた従来のこの種検出
装置は該スイツチ又はこれに連動するレバー等を
カセツトハーフの孔の位置に当接させて孔の有無
を判別するようになつている。 As described above, the conventional detection device of this type using a switch is designed to determine the presence or absence of a hole in a cassette half by bringing the switch or a lever linked thereto into contact with the position of the hole in the cassette half.

整しなければならない問題がある。 However, since there is a tolerance in the size of the cassette half and the size varies within that tolerance, in order to detect the above-mentioned hole on the top surface of the cassette half, the configuration of the conventional device is such that when the switch or lever is inserted into the hole. There is a problem where you have to adjust the switch so that it turns on.

するように構成したことを特徴とする。 The present invention has been made to improve the problems of the prior art, and includes a member for detecting the upper surface of the cassette half, and a switch for detecting the hole on the upper surface of the cassette half is interlocked with the member, thereby detecting the cassette half. It is characterized in that it is configured to operate with the upper surface of the half as a reference surface.

検出用のスイツチである。 The present invention will be described below with reference to the embodiments shown in the drawings. In FIG. 1, reference numeral 1 indicates a support column fixed at a predetermined location in a cassette tape recorder; 2, a rigid plate rotatable about the support support 1;
3, 4 and 5 were mounted on plate 2, respectively.
This is a switch for REC detection, chrome tape detection, and metal tape detection.

動し、カセツトハーフ6の上面の各孔に嵌入して
動作する。 When a cassette is inserted into a tape recorder, the rigid plate 2 rotates freely around the support 1, so that the claws a of the plate 2 are attached to the cassette half 6.
It is detected by coming into contact with the top surface of the At this time, each of the detection switches 3, 4, and 5 operates in conjunction with the rotation of the rigid plate 2, and is fitted into each hole in the upper surface of the cassette half 6.

面倒な調整作業は不要である。 In this case, the size of the cassette half 6,
Alternatively, even if the positions vary, the claw a always detects the top surface of the cassette half 6, so there is no change in the relative position of each detection switch interlocked with this and the claw a, and the detection switch always detects the upper surface of the cassette half 6. Operates using the top surface as a reference surface. Therefore, if the relative positional relationship is determined in advance, the troublesome adjustment work as in the prior art described above is unnecessary.

る。 FIG. 2 shows another embodiment of the present invention, in which each switch 3, 4, 5 is provided with a cassette half upper surface detection claw 7 instead of the rigid plate. 8 is a hole detection claw, and 9 is a contact point. When the hole detection pawl 8 fits into the hole while the detection pawl 7 is in contact with the upper surface of the cassette half, the contact 9 closes and the hole is detected.
本実施例では個々のスイツチに検出爪7を設け

自由に装着できる。 In this embodiment, each switch is provided with a detection claw 7, so that it can be mounted relatively freely in a predetermined position on the tape recorder.

時の調整作業を不要にすることができる。 As explained above, according to the present invention, when operating the hole detection switch of the cassette half, the detection switch is operated by using the upper surface of the cassette half as a reference surface to compensate for variations in the size of the cassette half and variations in its position. This eliminates the need for adjustment work during installation.
