Reference numerals 4 and 55 denote metal plates as left and right stoppers of the shutter, which are arranged in parallel with each other. A pair of rails 52 and 53 orthogonal to the stoppers 54 and 55 are stretched between the stoppers 54 and 55. A shutter 51 (corresponding to the shutter 13 in FIG. 5) is attached so as to be movably guided by the rails 52 and 53.

In FIG. 1A, the shutter 51 closes an insertion / removal opening 50 (corresponding to the insertion / removal opening 12 in FIG. 5) provided on the front panel 2d (see FIG. 5), and one of the left and right edges of the shutter 51 is shown. The edge portion of, i.e., the edge portion on the right side is in contact with the stopper 55. Also, FIG. 1B shows
The state in which the shutter 51 has moved slightly to the left from the state of FIG. 1A is shown.

Reference numerals 56 and 57 are leaf springs, and a leaf spring mounting portion 58 formed by bending a part of the stopper 55.
Is installed.

FIG. 2 shows a side view of these leaf springs 56 and 57. As is apparent from FIG. 2, these leaf springs 56, 5
7 is curved. The shutter 51 moves to the right from the position indicated by the solid line (see FIG. 1B), and as shown in FIG. 1A, one of the left and right edges of the shutter 51, that is, the right edge toward When abutting against the stopper 55, the leaf springs 56 and 57 shown by solid lines are used for the shutter 5
The leaf spring 5 is pressed by the right edge portion toward 1 and deforms like leaf springs 56 'and 57' shown by the broken line.
6'and 57 'allow the shutter 51 to move to the front panel 49 (see FIG.
(Corresponding to the front panel 2d), and closes the insertion / removal opening 50 of the front panel 49 so as to seal.
Incidentally, 51b (51'b) which is a part of the shutter 51 will be described later.

In this way, the shutter 51 is attached to the panel 49.
When closing the insertion / removal opening 50 (12) of
7 presses the right edge side of the shutter 51 toward the front panel 49 in FIG. 1, and the means of pressing the left edge side of the shutter 51 toward the front panel 49 in FIG. This will be described with reference to FIG.

As shown in FIGS. 3A and 3B, the shutter 51

The tubular body 60 is fitted into the rail 52 between the convex portions 51 a and 51 b of the shutter 51. In addition, 51b 'in FIG. 2 shows the convex part after the convex part 51b is moved.

On the other hand, the rail 52 is, as shown in FIG. 3C,
The right side from the point P has a circular cross section, while the left side from the point P has a D-shaped cross section. Correspondingly, the tubular body 60 has
Since a through hole having a D-shaped cross section is provided, the cylindrical body 60
Can move only on the left side of the point P on the rail 52. Then, as shown in FIG. 3A, when the right side edge of the shutter 51 hits the stopper 55, the cylindrical body 60 is positioned between the point P and the right side surface of the left projection 51 a of the shutter 51. , The position of the point P is set. And
At this time, a curved leaf spring 61 is mounted on the shutter 51 so as to come into contact with the tubular body 60.

Thus, as shown in FIG. 3B, when the right edge of the shutter 51 is separated from the stopper 55,
The tubular body 60 is positioned on one of the portions of the D-shaped cross section on the rail 52, but when the shutter 51 moves to the right from the state of FIG. 3B, the right edge of the shutter 51 is changed as shown in FIG. 3A. When abutting against the stopper 55, the tubular body 60 rides on the curved leaf spring 61, and the tubular body 60 and the leaf spring 6 are engaged.
The shutter 51 is pressed against the front panel 49 side by the cooperation of the above-mentioned 1.
0 is closed by a shutter 51 so as to be hermetically closed.

Although not shown in the drawing, a convex portion corresponding to the convex portions 51a and 51b in FIG. 3 is also provided on the lower side of the shutter 51, and these two convex portions are located on the lower side in FIG. A loose through hole through which the rail 53 passes is provided. A tubular body corresponding to the tubular body 60 in FIG. 3 is provided between the convex portions on the lower side of the shutter 51. Further, the lower rail 53 has the same shape as the upper rail 52, and the tubular body inserted into the lower rail 53 also has the same shape as the tubular body 60. Further, when the right edge of the shutter 51 abuts on the stopper 55, a leaf spring similar to the leaf spring 61, which is brought into contact with the cylindrical body inserted through the lower rail 53, is provided on the lower surface of the shutter 51. Installed.

When the right edge of the shutter 51 abuts on the stopper 55, the lower left side of the shutter 51 also rides on the plate spring having a curved cylindrical body, and the shutter cooperates with the cylindrical body and the plate spring. 51 is pressed against the front panel 49 side, and the insertion / removal port 5 of the front panel 49
0 is closed by a shutter 51 so as to be hermetically closed.

The shutter 51 can be moved manually, but here, it can be moved by a motor. The drive means of the shutter 51 by this motor is shown in FIG.
Will be described with reference to.

An overhanging portion 51c is provided below the shutter 51 at a right angle thereto, and a rack 51d is formed on the side surface of the overhanging portion 51c. A small gear (pinion) 62 that meshes with the rack 51d is provided. This pinion 62
Is rotatable about an axis 62X. Further, a small gear 63 that meshes with this small gear 62 is provided, and its rotation shaft 63
X is rotated by the motor 64. Thus, the shutter 51 moves left and right according to the rotation direction of the motor 64. In FIG. 4, for example, the moving direction of each member when the shutter 51 moves to the left is shown by an arrow.

In the above example, the case where the recording medium is a tape cassette has been described, but the recording medium is not limited to this, and may be a magnetic disk, an optical disk, a magneto-optical disk, or the like.
