１を本体３に対して昇降可能に構成している。 Figures 1a and 1b are a side view and a rear view, respectively, showing the device for preventing incorrect insertion of a cassette according to the present invention.
1 is a cassette storage frame provided with a protrusion 1a at a predetermined position inside thereof to engage with the groove 2a. The cassette storage frame 1 has a pair of left and right short links 5, 5 and long links 6, 6, and a main body 3.
The guide pins 5a, 6a provided at the ends of both links are connected to guide holes 7', 1' provided in the side plate 7 and the cassette storage frame 1, respectively. The cassette storage frame 1 is configured to be movable up and down relative to the main body 3.

1 is a lid opening pin for opening the lid of cassette 2, 10
is the angle at which the lid opening pin 11 is attached.
上記構成のカセツト誤挿入防止装置は次の通り
作動する。 The cassette erroneous insertion prevention device configured as described above operates as follows.
先ず、第２図はカセツト２をカセツト収納枠体
１に挿入した状態を示しており、この時、該カセ
ツト２と該カセツト収納枠体１とのクリアランス

確実に阻止する。 First, FIG. 2 shows the state in which the cassette 2 is inserted into the cassette storage frame 1. At this time, the clearance between the cassette 2 and the cassette storage frame 1 is narrow as shown by L1. Even if an attempt is made to insert the cassette 2 in the opposite direction by mistake, the protrusion 1a contacts the rear end surface of the cassette 2, which does not have an engagement groove, as shown in FIG. 4, and reliably prevents the insertion of the cassette 2. do.
又、第２図に示したカセツトの挿入状態から、

うにL3，L4の必要クリアランスを得、ロツク操
作を妨げないものである。 Also, from the inserted state of the cassette shown in Figure 2,
When the cassette storage frame 1 is lowered, the guide pin 5a at one end of the link 5 forming the link mechanism moves the guide hole 3 of the side plate 7 to the left in the figure, and the connecting shaft at the other end rotates clockwise in the figure. Therefore, when the loading condition shown in Fig. 3 is locked, the cassette 2
The top surface of the connecting shaft 4, which has a substantially semicircular cross section, faces the flat surface thereof. Therefore, as shown in the figure, the required clearance for L 3 and L 4 is obtained and the locking operation is not obstructed.
〈考案の効果〉
以上述べたように、本考案では装置自体に何ら
加工を施したり、部品を付け加えたりすることな
く、断面が略半円形状をなす連結シヤフトを用い

価値を有する。<Effects of the invention> As described above, the present invention eliminates the problem of incorrect cassette insertion by simply using a connecting shaft with a substantially semicircular cross section, without any processing or adding any parts to the device itself. This system automatically creates the necessary clearance for the locking mechanism as the loading operation occurs, and does not increase the number of manufacturing steps or costs, and also eliminates product variations by creating a wide clearance during loading. This has the practical value of increasing product reliability.
