ープカセツト内のリールとを係合せしめる構成が
広く使用されている。 Conventionally, in magnetic recording and reproducing devices, a cassette mounting table has been constructed so as to be able to move toward and away from a reel table.
A widely used configuration is that after a tape cassette is mounted on a cassette mounting stand that is separated from the reel stand, the cassette mounting stand is moved toward the reel stand, and the reel stand and the reel in the tape cassette are engaged. ing.

にテープカセツトを垂直方向に立てた状態で使用
する装置にこの傾向が強かつた。 In such a configuration, there is a problem in that when the cassette mounting table is moved, the reel inside the tape cassette rotates, causing the tape to become slack within the cassette. This tendency was particularly strong in devices in which the tape cassette was used in a vertically erected state.

台に設けた点に特徴を有するものである。 The present invention provides a means to solve this problem, and when the tape cassette is mounted on the cassette mounting table, it engages with the reel inside the tape cassette,
This device is characterized in that the cassette mounting table is provided with a braking member that prevents the rotation of the cassette.

態にある。 A bottom plate 1 constituting this cassette mounting table is provided with through holes 2, 2 into which a reel stand (not shown) is inserted. The tape cassette is inserted from the direction of arrow A. Reference numeral 3 designates an annular engagement member as shown in FIG.
is provided in a direction perpendicular to the radial direction of the annular body.
The outer periphery of this engaging member 3 is held by a leaf spring material 5, and this leaf spring material 5 is fixed to the cassette insertion opening side on the back surface of the bottom plate 1 of the cassette mounting table with screws 6, etc., as shown in FIG. has been done. In this attached state, the engaging member 3 is located in the through hole 2 of the bottom plate 1 of the cassette mounting table, and the engaging protrusions 4, 4' are slightly protruded from the upper surface of the bottom plate 1.

阻止するものである。 When the tape cassette 8 is inserted into the cassette mounting table along the bottom plate 1, the engaging protrusion 4 is pressed downward by the curved surface provided at the tip of the tape cassette 8, as shown in FIG. The tape cassette 8 is inserted while being deformed. When the tape cassette 8 is inserted to the normal insertion position, the reel stand insertion hole 10 provided in the bottom plate 9 of the tape cassette 8 is positioned above the engaging protrusions 4, 4', as shown in FIG. Therefore, the engaging protrusions 4, 4' are moved upwardly and returned by the force of the leaf spring 5, and the engaging protrusions 4, 4' engage with the side surface of the end of the reel 11 in the tape cassette. This prevents rotation.

である。 When the cassette placement is moved toward the reel stand 12 in this state, the reel stand 12 and the reel 11 engage with each other as shown in FIG. 6, and the reel 11 is lifted up from the cassette bottom plate 9 by the reel stand 12. Thus, the reel 11 and the engaging protrusions 4, 4'
The engagement with is released. Therefore, the engaging protrusions 4, 4'
This eliminates the increase in load on the reel 11 due to this.

もなくなるものである。 As described above, according to the present invention, when a tape cassette is inserted and mounted on a cassette mounting table, a braking force is applied to the reel in the tape cassette, so that the reel is no longer necessary due to the impact of the movement of the cassette mounting table. It rotates and prevents the tape from sagging inside the cassette.
