Description

【考案の詳細な説明】（技術分野）本考案は縦型テープレコーダ等の機器本体前面
に配置されたカセツトホルダーの開閉装置に関す
る。[Detailed Description of the Invention] (Technical Field) The present invention relates to an opening/closing device for a cassette holder placed on the front surface of a device body such as a vertical tape recorder.

（従来の技術及びその問題点）縦型のテープレコーダは、その機器本体前面に
設けたカセツトホルダーにカセツトを収納して録
音、再生を行う。(Prior Art and its Problems) A vertical tape recorder performs recording and playback by storing a cassette in a cassette holder provided at the front of the main body of the device.

カセツトホルダーの開閉装置は第３図の側面概
略図で示す様に、カセツトホルダー１を捩りコイ
ル状のバネ２とダンパ３により支持し、カセツト
ホルダー１の上部に突設した突片１１をピンＰに
掛止させている。 As shown in the schematic side view of FIG. 3, the cassette holder opening/closing device supports a cassette holder 1 by a torsion coil spring 2 and a damper 3, and connects a protrusion 11 protruding from the top of the cassette holder 1 to a pin P. It is hung on.

このカセツトホルダー１の開閉動作は第４図で
示す如く、バネ２によるバネ力によつて開き、一
方ダンパ３によつてその開き速度を規制するもの
で、全体として緩慢な開行程を呈する。 As shown in FIG. 4, the opening/closing operation of the cassette holder 1 is performed by the spring force of the spring 2, and the opening speed is regulated by the damper 3, resulting in a slow opening stroke as a whole.

ともなつている。 This slow opening process gives the tape recorder a luxurious feel. However, if the return force of the spring 2 is large, it will overcome the regulating force of the damper 3 and the opening speed will increase. On the other hand, if the regulating force of the damper 3 is greater than the biasing force of the spring 2, the opening stroke may be too slow or the opening may not open at all. Therefore, the biasing force of the spring 2 and the regulating force of the damper 3 are not balanced and adjustment is required, and this is also a cause of complaints such as the opening speed being too fast or too slow.

きるものである。(Means for solving the problems) This invention was devised in view of the above problems.
The device includes a cassette holder attached to the main body of the device so as to be openable and closable, an arm portion provided on the cassette holder to be hooked to the cassette holder, a spring for biasing the cassette holder in the opening direction, and a spring attached to the spring. It consists of a damper that regulates the force and a holding means that engages with the cassette holder to hold the cassette holder in a closed state. is able to press and bend the arm from the same direction as the direction in which the cassette holder urges the hanging portion, and is in a position where it can be separated from the arm when the cassette holder is opened after the initial state. , since the configuration includes a pressing portion for increasing the urging force applied to the cassette holder in the initial state,
Without adopting a large-scale configuration, in the initial state of the opening process of the cassette holder, the pressing force from the pressing part is added to the characteristics of the spring, the added force biases the cassette holder, and after the initial state, the spring Since the cassette holder will open according to the characteristics of the spring, by simply selecting a damper that matches the characteristics of the spring, the cassette holder can be opened reliably in the initial state of the opening process, and the cassette holder will not open after the initial state. will be able to open slowly. In other words, the high-class feel of the tape recorder can be maintained.

力より大きな力で付勢している。 That is, a torsion coil spring 2 is provided on the side of the cassette holder 1 and has a coiled portion 2a wound around the center thereof. This spring 2 extends from one end of the coiled part 2a to the first arm part 2.
b is extended, and this first arm portion 2b is fixed to the device main body H. A second arm portion 2c is extended from the other end of the coiled portion 2a, and this second arm portion 2c is fixed to the cassette holder 1. It is hung on a hanging pin _P1 provided on the side of the. Further, the main body H of the device is provided with an arm portion A, and this arm portion A is provided with a pressing pin _P2 so as to face the hooking pin _P1 via the second arm portion 2c. Pressing pin _P2 is in the second position when the cassette holder 1 is in the initial state opened by a predetermined amount from the closed state.
The second arm 2c presses and bends the opposite point of the arm 2c from the point where it is hooked to the hook pin P1 in the same _direction as the direction in which the second arm 2c urges the hook pin _P1 , and the cassette is The holder 1 is biased with a force greater than that simply exerted by the second arm portion 2c.

定の開き速度が得られる。 When the cassette holder 1 is in the closed state, the protrusion 11 is engaged with the pin P. At the beginning of the opening stroke, the protruding piece 11 comes off the pin P and the cassette holder 1 is tilted forward by the return force of the spring 2. At this time, since the spring 2 is urged by the pressing pin _P2 , the cassette holder 1 can be reliably opened. However, since the deflection of the spring 2 by the pressing pin P ₂ is small, the biasing force is effective at the beginning of the opening stroke, and as the cassette holder 1 gradually opens, the return force of the spring 2 causes the retaining pin to
Press P ₁ to open. On the other hand, when the urging force by the pressing pin _P2 is no longer applied, the regulating force of the damper 3 acts strongly, and the cassette holder 1 slowly and smoothly opens. That is, spring 2 due to pressing pin P ₂
The pressing force applied by the pressing pin P2 acts at the beginning of the opening stroke when the projecting piece 11 comes off the pin P, and the pressing by this pressing pin _P2 is released as the predetermined opening stroke progresses, and after that, the spring 2
A predetermined opening speed can be obtained by balancing the return force of the damper 3 with the regulating force of the damper 3.

を一層高めることができる。(Effects) As described above, according to the cassette holder opening/closing device of the present invention, the opening process of the cassette holder is performed reliably in the initial state and slowly after the initial state, which improves the luxury feel of the tape recorder. can be further enhanced.

でき、設計が容易になる。 In addition, since the arm portion of the spring (second arm portion 2c) is pressed by the pressing portion (pressing pin P ₂ ) and the force that urges the cassette holder is increased in the initial state of the opening process, Without significantly increasing the number of parts, and unlike when using a new spring, there is no need to consider optimizing the biasing force and arrangement of the two springs; only the arrangement of the pressing part is considered. By doing so, the optimum condition can be easily obtained and the design becomes easier.
