上下方向の動きが規制されている。FIG. 2 is an enlarged view of the leader 4a, and the leader body 7 includes a slant ball 8 and a guide roller holding portion 10.
A cylindrical boss 11 having a diameter smaller than the width of the groove 13a and a downward protrusion of the guide roller holding part 10 are formed on the lower surface. The cylindrical boss 11 is integrally provided with a pin 12 that receives a moving force via a driving force transmitting body 15. The leader 4a fits the cylindrical boss 11 and the lower end of the guide roller holding part 10 into the groove 13a from above,
In this state, the retaining ring 14 is attached to the chassis 3 to restrict vertical movement of the chassis 3.

を、溝１３ａ、 １３ｂ内で行なうことができる。The leaders 4a and 4b are 1. When the bottle 12 receives a force parallel to the chassis 3 from the driving force transmitting body 15 by some method, it is caused to reciprocate through the locus of the grooves 13a and 13b. Therefore, by freely changing the trajectory of the grooves 13a, 13b, the entire tape can be pulled out from the cassette 1 and wrapped around the drum cylinder 5, and the positioning member 6a can be used to install the vertical guide roller 9 and the slant ball 8 at desired positions. 6b To move on one's back (or in reverse)
can be performed within the grooves 13a, 13b.

The force θ pushes the leader 4aeX direction, and the positioning member 6
The leader 4a is positioned by the contact between the V-shaped protrusion a and the guide roller holding part 10, and the moment with the contact part a as a fulcrum is applied to the lower surface of the leader main body 7 and b.
In addition, the levelness of the leader 4a can be obtained. Furthermore, P
The force of sin θ is generated by the leader 4a when the guide roller holding part 1
Give a moment to rotate in the Y direction around the center of 0,
The side surface C portion of the cylindrical boss 11 is connected to the groove 20 of the positioning member 6a (
3) to determine the orientation of the leader 4a in the horizontal plane. In this way, the positions and orientations of the slant poles 8 and vertical guide rollers 9 of the leader 4a are determined.
従来のローディング機構は上述の如き構成であったため
、溝１３ａ、１３ｂの内側ガイド面を滑らかに研摩する
のが因難であシ、位置決め部材６ａ。Since the conventional loading mechanism has the above-described configuration, it is difficult to polish the inner guide surfaces of the grooves 13a and 13b smoothly, and the positioning member 6a.
６ｂに達するまでリーダー４．ａ、４ｂが溝１３ａ。Leader 4 until reaching 6b. a and 4b are grooves 13a.

再生装置のテープローディング機構を提供するにある。When sliding 13b, the side C portion necessary for positioning and the lower surfaces of the leader bodies 7a, 7b are worn out, making subsequent positioning unstable.An object of the present invention is to
To provide a tape loading mechanism for a magnetic recording/reproducing device capable of accurately maintaining the position and orientation of a leader while minimizing wear caused by movement of the leader.

響を与えない。The present invention provides a band-shaped guide plate in place of the conventional groove, and a leader is provided to be slidably suspended from the band-shaped guide plate.
However, in the case of a band-shaped guide plate, it is easy to polish the guide surface to make it smooth, and in such a structure, the sagging retaining part with the band-shaped guide plate is fixed by the movement of the leader. Wear does not affect the position and orientation of the leader in any way.
以下本発明の実施例を図面と共に説明する。Embodiments of the present invention will be described below with reference to the drawings.

８図に示すように構成されている。FIG. 6 is a plan view, and there are 1 on both sides of the drum cylinder 5.
A pair of band-shaped guide plates 16a and 16b are arranged, and the chassis 2
It is fixed to the chassis 2 or another chassis at both ends while floating a predetermined distance from the chassis. Band-shaped guide plate 16
A and 16b are thin plate-like bodies provided at positions corresponding to conventional grooves, and have the necessary width in the vertical direction, that is, in the direction perpendicular to the chassis 2'. Band-shaped guide plate 16a
, 16b, positioning members 6a and 6b are respectively fixed to one end. The readers 4a, 4b are constructed as shown in FIGS. 7 and 8.

点で相違している。The leader 4a includes a slant ball 8 on the leader body 7,
Vertical guide roller 9, guide roller holding section 10, cylindrical boss 11. It is similar to the conventional example in that it is constructed by attaching a pin 12 and a driving force transmitting body 15, but is different in that it has a guide pin 1z and a seven-shinge 18 above the leader body 7.

。A flange 18 is hung on the upper surface of the aforementioned strip-shaped guide plate 16a, so that the leader 4a is suspended from the strip-shaped guide plate 16a. As shown in FIG. 7, the driving force transmitting body 15
The power given to the leader 4a through the leader 4a
A counterclockwise rotational moment is applied to the As a result, the guide roller holding portion 10 is pressed against the band-shaped guide plate 16a, but since the contact surface of the band-shaped guide plate 16a is the surface of the material, friction and wear can be extremely reduced, and the direction of the leader 4a can be kept constant. can be kept.
帯状案内板１６ａの上方側面とフランジ１８間について
も、帯状案内板１６ａが単純な形状であって上方側面を
従来の溝側壁より滑らかに仕上げることができ、周部で
の摩擦および摩耗を小さくするととができる。Regarding the space between the upper side surface of the band-shaped guide plate 16a and the flange 18, the band-shaped guide plate 16a has a simple shape, and the upper side surface can be finished more smoothly than the conventional groove side wall, reducing friction and wear at the peripheral portion. I can do that.

Fig. 9 shows an embodiment in which the friction between the guide pins 17 and 19 is further reduced.
This reduces the friction between the guide plate 16a and the first guide plate 16a.
In FIG. 0, the upper side surface of the band-shaped guide plate 16a is formed by bending a plate-shaped material to reduce the friction between the band-shaped guide plate 16a and the flange 18.

This drop-off prevention part 18a is constructed by bending the flange 18 toward the frame-shaped guide plate 16a, and connects the band-shaped guide plate 16a to the guide pin 17 and the drop-off prevention part 1.
8a to prevent the leader 4a from falling off.

、摩耗抵抗を大幅に減らすことができ摩耗による保持方
向の変化を防止できる。The tape loading mechanism described in each embodiment has various advantages over conventional configurations. First, when the leader 4a is guided by a groove, the chassis 3t is made into a strength member to maintain the groove shape against the applied driving force, which results in an increase in size and limits the arrangement of nearby components. In the embodiment, since a pair of band-shaped guide plates 16a and 16b are used, adjacent space can be utilized for other components. Furthermore, since the band-shaped guide plates 16a and 16b are used, the outer surface is easier to process than grooves, and wear resistance can be significantly reduced, and changes in the holding direction due to wear can be prevented.
