Abstract

ตลับเทปแม่เหล็กที่มีขนาดเล็กมากประกอบด้วยฝาปิดด้านหน้าที่ถูกยึดไว้ให้หมุนได้ที่ส่วนแขนรับของมันเข้ากับตัวตลับในการที่จะเลือกทำการเปิดหรือปิดส่วนเปิดด้านหน้าของตลับเทปแม่เหล็กได้ด้วยการเปลี่ยนรูปแบบยืดหยุ่นตัวของฝาปิดด้านหน้าตัวตลับเทปมีส่วนผิวขอบอยู่บนผนังด้านข้างที่ยื่นตั้งฉากกับทิศทางในการหมุนของฝาปิดและซึ่งเข้าสัมผัสกับผิวด้านในของส่วนแขนรับเมื่อฝาปิดถูกเปิดไว้ ดังนั้นเมื่อฝาเปิดด้านหน้าอยู่ในสภาพเปิด ฝาปิดก็สามารถจะถูกป้องกันไว้จากการเคลื่อนที่ไปในแนวขวางของฝาปิดและก็จะถูกป้องกันมิให้หลุดออกจากตัวตลับได้ นอกจากนั้นตลับเทปแม่เหล็กยังสามารถที่จะถูกดีดออกจากเครื่องบันทึกและ/หรือเล่นเทปได้อย่างสะดวก The very small magnetic tape cassette has a front cover that is held in place that rotates its receiver arm to the cassette in order to open or close the front opening of the magnetic tape cassette. The flexible deformation of the cassette front cover has a rim surface on the side wall that extends perpendicular to the direction of rotation of the cap and which touches the inner surface of the sleeve when the cap is touched. keep it open Therefore, when the front cover is open, it is in open condition. The cap can also be prevented from horizontal movement of the cap and can be prevented from falling out of the cassette. In addition, magnetic tape cassettes can be easily ejected from the recorder and/or played back.

Claims

1. A magnetic cassette tape consists of (a) a cassette with a front opening (b) a front cover. It is made up of the main torso with the forearm that are perpendicular to the main torso at its two ends. The front cover is installed so that it rotates on the front of the cartridge at the support arm. With a number of axes in their order In order to choose to open and close the front opening of the cartridge And where the arm is set away from the end of the cartridge. When the front cover is in the closed state and (c) the protrusion provided on the said cassette on the support. The front cover is fixed in such a way that it rotates with the axis. With the said overhang protruding along the axis of the said item As a result, the support arms stick in an axial position with the said protrusion in order to climb up on the overhang. When the front cover has been turned to open state. In order to provide stability to the front cover in its axis.

2. Magnetic tape cassette according to claim 1, which the cores have different diameters respectively. And each part of the support arm has a fan-like part spread out around from the weight support of the arm towards the main body of the cap. And there is a grip that can be attached to the arm section when the front cover is in the open state. By the said adhesion part Each section is arranged to resemble the individual support arms. The serrated sections were arranged on both sides of the front opening respectively. The notches are lowered towards the rear compared to the middle of the front opening.
