In particular, there is a growing demand for automatic assembly response due to the miniaturization of the device and the improvement of assembly.

여기에 그 종래예 및 그 문제점을 설명한다.Here, the conventional example and the problem are demonstrated.

제1도에 있어서, (1-1)은 판금으로 구성된 새시기체이며, 여기에는 자기테이프인출부재(5)(6)의 안내홈(3-1)(4-1)이 형성되어 있다. 상기 새시기체(1-1)상에는, 회전자기헤드드럼(도시하지 않음)을 재치하는기판(2), 자기테이프인출부재(5)(6)를 소정의 자기테이프인출위치에서 위치결정하기 위한 위치결정고정부재(7)(8)등이 부착되어 있다. 자기테이프인출부재(5)는 제2도 및 제3도에 표시한 바와 같이, 비스(5-3)로 결합된 테이프인출부재본체(5-1)와 압압판(5-2)으로 새시기체(1-1)를 끼워서 쓸데없이 빠지지 않도록 부착되어 있으며, 새시기체(1-1)상을 안내홈(3-1)에 따라서 접동하여, 제1도에 표시한 테이프카세트의 자기테이프를 꺼낼 수 있는 위치와, 제2도에 표시한 자기테이프인출부재의 위치결정고정부재(7)에 의해서 위치결정고정되어 자기테이프를 회전자기헤드드럼에, 당접시킬 수 있는 위치와의 사이를 왕복이동한다.In Fig. 1, reference numeral 1-1 denotes a cage body made of sheet metal, and guide grooves 3-1 and 4-1 of the magnetic tape takeout members 5 and 6 are formed therein. On the cage body 1-1, a position for positioning the substrate 2 on which the rotating magnetic head drum (not shown) and the magnetic tape extracting members 5 and 6 are positioned at a predetermined magnetic tape extracting position. Crystal fixing members 7 and 8 are attached. As shown in FIGS. 2 and 3, the magnetic tape drawing member 5 has a tape drawing member body 5-1 and a pressing plate 5-2 joined together with a screw 5-3. (1-1) is inserted so that it will not be unnecessarily pulled out, and the magnetic tape of the tape cassette shown in FIG. 1 can be taken out by sliding the upper body (1-1) on the guide groove (3-1). The position is fixed by the positioning fixing member 7 of the magnetic tape extracting member shown in FIG. 2 and the position where the magnetic tape can be brought into contact with the rotating magnetic head drum is reciprocated.

종래, 이 자기테이프인출부재(5)의 새시기체(1-1)에의 부착조립방법은 다음과 같았다. 즉, 제4도에 도시한 바와 같이, 테이프인출부재본체(5-1)는 새시기체(1-1)의 상부로부터, 또 압압판(5-2)은 새시기체(1-1)의 하부로부터 부착하여, 새시기체(1-1)를 끼워서 비스(5-3)로 부착하는 샌드위치 조립작업이 필요하며, 새시기체를 반대로 뒤집어서 조립하는 등의 복잡한 작업을 필요로 하고 있었다. 이것을 개선한 다른종래예가 제5도, 제6도에 표시한 것이다.Conventionally, the attaching and assembling method of the magnetic tape drawing member 5 to the casing body 1-1 is as follows. That is, as shown in FIG. 4, the tape extracting member body 5-1 is from the upper part of the casing body 1-1, and the press plate 5-2 is the lower part of the casing body 1-1. The sandwich assembly work of attaching from the base body 1-1 and attaching it to the vis 5-3 is required, and complicated work such as inverting the new body body in reverse and assembling is required. Another conventional example of improving this is shown in FIG. 5 and FIG.

At one end (rear of the rotating magnetic drum) of the guide grooves 3-2 and 4-2 of the cage body 1-2, the full length l 1 of the magnetic tape extracting member 5 is moved from the Z direction. The cutout portion 5a is formed by the insertable length l 2 and the width direction by the insertable width from the Z direction. In this way, the tape take-out member 5 is assembled in advance, and it is attached to the guide groove of the cage body 1-2 in the Z direction perpendicular to the guide groove, and then moved in the X and Y directions parallel to the guide groove. As shown in Fig. 5, the assembly is possible, and the conventional example of Fig. 1 is improved. However, in the conventional example of FIG. 5, " a cutout portion having a size that the magnetic tape extracting member 5 can be inserted from the Z direction at one end of the guide groove portion 3-2 of the cage body 1-2. It is necessary to form 5a), and it is difficult to form such a cutout part because of the miniaturization of the device, especially the size of the new body, ie, the miniaturization becomes difficult. ) Is an attachment and granulation step to the new body (1-2), and requires a two-way moving step of a Z-direction moving step and an XY plane moving step, and the magnetic tape extracting member is attached to the new starting body in one step. Improvement of assembly process is needed. " Has problems and improvement items.

FIG. 7 is a perspective view of the magnetic recording and reproducing apparatus of the present invention, and FIG. As shown in FIG. 7, the casing body 1-3 is formed of a molded article (for example, die-cast of aluminum alloy), and has an attachment portion 2 and magnetic tape pullout that directly mount the rotating magnetic head drum. The guide grooves 3-3 and 4-3 of the members 5 and 6 are provided. As shown in Figs. 7 and 8, the guide grooves 3-3 and 4-3 have an outer edge of the cage body 1-3 at one end thereof (the rear side of the cage body). It has opening part (denoted A) about (1-3a). Therefore, as shown in FIG. 8, the magnetic tape extracting members 5 and 6 move only to one plane (XY plane) from the outside of the cage body 1-3 and move to the cage body 1-3. It can be attached as much as possible. After attaching the magnetic tape extracting members 5 and 6, the fixing members 7 and 8 similar to those described in FIG. 1 are attached. 20, 21, 22, and 23 shown in FIG. 7 are bission holes for attaching the fixing members 7 and 8. As shown in FIG. In Fig. 8, the outer edge portion 1-2a of the cage body 1-2 shown in Figs. 5 and 6 of the conventional example is indicated by a dotted line, but the guide groove ( Since one end of 3-3 has an opening portion at the outer edge of the cage body 1-3, the cage body 1-3 in the present invention is a chassis for the cage body 1-2 of the conventional example. In the rear of the base, as shown in FIG. 7 and FIG. 8, it can be shortened by ΔL, contributing to the miniaturization of the entire apparatus.

제8도∼제9도와 같이, 안내홈(3-3)(4-3)의 개구부를 외연부에 설치가능하게 된 것은, 도면에 표시한바와 같이 새시기체를 알루미늄의 다이캐스트에 의한 성형품으로 구성했기 때문이다. 종래 새시기체를 판금등으로 구성하면, 새시의 강성등이 저하되어, 자기테이프장치의 주행로(走行路)에 악영향을 미치게하며, 특히 재생화질이나, 테이프기록재생의 호환성(互換性)에 큰 영향을 주는 등 문제가 있었다. 본 발명과 같이 새시기체를 성형품, 예를 들면, 알루미늄합금의 다이캐스트로서 구성하므로서, 상기 개구부(A)의 근처에 보강용의 리브부(1-3b)(1-3c)를 간단하게 일체적으로 형성할 수 있어서, 새시의 기계적 강도를 저하시키는 일없이, 조립의 합리화와 더불어 장치의 소형화도 가능해진다. 또, 이상에서 설명한 구성은, 자기테이프인출부재(6)쪽에 대해서도 마찬가지다.As shown in Figs. 8 to 9, the openings of the guide grooves 3-3 and 4-3 can be provided at the outer periphery, as shown in the drawing, and the new body is formed by die casting of aluminum. Because it was configured. If the conventional chassis is made of sheet metal or the like, the stiffness of the chassis is lowered, which adversely affects the driving path of the magnetic tape device, and is particularly effective in reproducing image quality and compatibility of tape recording and reproducing. There was a problem, such as affecting. As the present invention is constructed as a die cast of a molded article, for example, an aluminum alloy as in the present invention, the rib portions 1-3b and 1-3c for reinforcement are easily integrated in the vicinity of the opening A. It is possible to form the structure, and it is possible to reduce the mechanical strength of the chassis and to reduce the size of the device as well as the rationalization of the assembly. In addition, the structure demonstrated above is the same also about the magnetic tape take-out member 6 side.

또, 제9도에 표시한 바와 같이, 자기테이프인출부재(5)를 새시기체(1-3)의 안내홈에 대해서 비스듬한방향의 평명이동(X,Y,Z면을 포함함)에 의해서 새시기체에 꽂아넣어서 부착하고, 그뒤, 테이프카세트로부터 자기테이프를 인출할 수 있는 위치에, 안내홈에 평행인 X,Y면에서 이동시키므로서, 장치의 소형화만을 도모하는 응용에도 고려할 수 있다.In addition, as shown in FIG. 9, the magnetic tape extracting member 5 is sashed by a moving plane (including the X, Y, and Z planes) in an oblique direction with respect to the guide groove of the cage body 1-3. It can also be considered for applications in which the device can only be miniaturized by being attached to the body and then moved on the X and Y planes parallel to the guide grooves in a position where the magnetic tape can be drawn out from the tape cassette.

이상과 같이 해서, 제7도∼제9도에 예시한 본 발명의 자기기록 재생장치는, 상기한 종래장치의 문제점 및 개선항목을 해결하였다.As described above, the magnetic recording and reproducing apparatus of the present invention illustrated in FIGS. 7 to 9 solves the problems and improvement items of the above-described conventional apparatus.
