Description

[Detailed description of the invention] Industrial application field The present invention is a tape storage case that is incorporated into a recording/playback device, and in which a holder into which a tape storage case is inserted is moved to a mounting position and the tape storage case is mounted. Relating to a mounting device.

BACKGROUND TECHNOLOGY In a conventional tape storage case mounting device, as a means for holding a tape storage case (hereinafter referred to as a tape cassette) in a holder, for example, an abutment that abuts the tape cassette is placed on the top surface of a holder into which the tape cassette is inserted. and a biasing member that biases the abutment member in a direction to press the top surface of the tape cassette, and when the tape cassette is inserted, the abutment member rotates to a position away from the tape cassette, and the tape cassette is inserted. As the holder with the tape cassette placed on the rear bottom plate moves, the abutment member energized by the biasing member rotates to press and hold the tape cassette toward the holder bottom plate.

Problems to be Solved by the Invention However, in the tape storage case mounting device having the above structure, when the tape cassette inserted halfway into the holder is pressed by the abutting member, the tape cassette is pressed against the holder as the abutting member moves. When attempting to pull the tape cassette into the insertion completion position within the holder, as the contact member moves, the tape cassette will slide on the holder bottom plate against the sliding resistance of the combined weight of the tape cassette and the pressing force of the contact member. However, the disadvantage was that the tape cassette did not move smoothly. In particular, when inserting a tape cassette into a holder with the short side facing forward and moving the tape cassette in the direction of the long side, the moving distance is longer than when inserting the tape cassette into the holder with the long side facing forward. Therefore, it has been desired that the sliding resistance be small when the tape cassette is moved together with the abutting member.

In addition, as a conventional tape storage housing mounting device,
For example, there is a device disclosed in Japanese Patent Application Laid-Open No. 139359/1983. The tape storage case mounting device described in this publication is provided with a pair of pressing springs and a positioning spring that sandwich the tape storage case mounted in the holder from the upper and lower surfaces. However, the pair of pressing springs are leaf springs directly fixed to the ceiling plate of the holder, while the positioning spring is a leaf spring directly fixed to the bottom plate of the holder.

In addition, these leaf springs are always biased in the direction of pressing the tape storage case against each other (closed state) due to their own elastic force, and when inserting the tape storage case into the holder, these leaf springs are Since the tape is inserted against the elastic force of the leaf spring, an excessive load resistance is generated on the tape storage case during insertion, resulting in a disadvantage that the insertion sensation is significantly reduced. Furthermore, problems such as damage to the upper and lower surfaces of the tape storage case occur due to these leaf springs.

In addition, the tape storage case is pressed against the bottom of the holder by the pressing spring, and the positioning spring lifts the tape storage case upward, so although the tape storage case is pinched, the tape In order to reliably place the storage case on the bottom surface of the holder, the elastic force of the positioning spring acts to lift the tape storage case upward, which is rather inconvenient.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a tape storage case mounting device that eliminates the above-mentioned drawbacks.

Means and Effects for Solving Problems Tape storage in which a holder into which a tape storage case is inserted and held is moved together with the tape storage case, and the tape storage case is attached to a predetermined mounting position of a recording/playback device. The case mounting device has a contact portion with which the tape storage case to be inserted comes into contact, and the tape storage case contacts the corresponding contact portion in the latter half of the insertion operation of the tape storage case. a sliding member that slides along the holder and moves integrally with the holder to a predetermined mounting position, one end of which is rotatably supported by the sliding member, and the other end of which is rotatably supported within the holder; a pair of expandable gripping members that can grip the tape storage case inserted from the upper and lower surfaces via a spring member; The pair of gripping members are placed in an open state where they are separated from the upper and lower surfaces of the tape storage housing against the elastic force of the spring member, and the tape storage housing is brought into contact with the corresponding contact portion of the sliding member. After that, the pair of gripping members are held between the upper and lower surfaces of the tape storage case via the spring member in a closed state in conjunction with the sliding movement of the sliding member along the holder. Then, the sliding member having the gripping member that grips the tape storage case is moved in the moving direction of the tape housing, and the tape storage case gripped by the gripping member is moved accordingly, and the tape storage case is moved. It is designed to smoothly move the body to the insertion completion position.

_{As 6 moves} in _{the direction of arrow} The upper and lower surfaces of the tape cassette 2 can be held close to each other.

Note that elongated holes 5a 3 and 5b 1 are bored in the bottom surface 5a and top surface 5b of the holder 5, extending in the directions of the arrows X ₁ and X ₂ over the movement range of the openings 14a ₁ and _{14b 1 of} the sliding member ₁₄ . There is. Therefore, the bent portions 15a, 16a of the gripping members 15, 16 face the elongated holes 5a ₃ , 5b ₁ of the holder 5 from the openings 14a ₁ , 14b ₁ of the sliding member 14, respectively.

Furthermore, projecting pins 14c ₁ and 14c ₂ that project laterally are provided on the front and rear sides of the side portion 14c of the sliding member 14. The protruding pin 14c ₁ is fitted into the guide groove 9a, and the protruding pin 14c ₂ is fitted into the L-shaped guide groove 9b formed in the bracket 9. Also,
As shown in FIG. 3, the protruding pin 14c ₁ is engaged with the elongated hole 20a ₁ of the rotating arm 20a of the drive transmission mechanism 20 attached to the bracket 9. As shown in FIG.

A gripping member 15 that grips the tape cassette 2 by this drive transmission mechanism 20 and the sliding member 14,
16 in the moving direction of the tape cassette 2 (arrow X ₁ ,
A moving mechanism is configured to move the tape cassette 2 held by the holding members 15 and 16 in the _X2 direction).

Therefore, the sliding member 14 is rotated by the rotating arm 20a.
When the holder 5 rotates, it slides on the outside of the holder 5 in the horizontal direction guided by the guide grooves 9a and 9b, and can move together with the holder 5 when moving up and down.

As shown in FIG. 4, 21 is an opening/closing lid of the insertion port 3b, and the shafts 21a, 21b on both sides are connected to the brackets 9, 1.
The lid is closed by the elastic force of a torsion spring 22 wound around the shaft 21a.
Reference numeral 23 denotes a lid opening locking member which abuts against the lower edge of the lid 2b of the tape cassette 2 lowered to the mounting position to lock and open the lid 2b, and is bent integrally with the bracket 11. The bracket 12 is mounted on the upper part of the front bracket 10 and the upper part of the rear bracket 11, and has an opening 24 at the bottom for tape loading.

Next, the operation of inserting and mounting the tape cassette 2 into the tape storage case mounting device 1 constructed as described above will be explained.

As shown in FIGS. 2A and 2B, the tape cassette 2 is pressed in the direction of arrow _X1 by applying it to the insertion slot 3b with the short side of the tape cassette 2 having the lid lock release button 2a as the front. The tape cassette 2 is inserted into the holder 5 by pressing the opening/closing lid 21 on the front side against the elastic force of the spring 22 to open the lid.

As shown in FIG. 1, when the tape cassette 2 is inserted into the holder 5, the groove 2c on the bottom surface of the tape cassette 2 fits into the protruding pin 8 of the bottom plate 5a, preventing insertion in any direction other than the above. .

Further, the tape cassette 2 is inserted in the direction of arrow _X1 , with its insertion direction being regulated by the protruding pin 8, and comes into contact with the contact portion 14d of the sliding member 14.

When inserting the tape cassette 2 into the holder 5, the gripping members 15 and 16 both have bent portions 15a and 16a.
The base portions of the holder 5 are brought into contact with the wide portions 5c ₁ and 5c ₂ of the holder 5, and are in an open state. That is, the gripping member 1
The bent portions 15a, 16a of 5, 16 are separated from the elongated holes 5a ₃ , 5b ₁ of the holder 5, and are at a height position where they fit into the openings 14a ₁ , 14b ₁ of the sliding member 14, and are not inserted. The upper and lower surfaces of the tape cassette 2 are spaced apart from each other. Therefore, the gripping members 15 and 16 do not interfere with the insertion of the tape cassette 2 into the holder 5.

Further, when the rear side of the tape cassette 2 is pressed until it is substantially flush with the front surface 3a of the recording/reproducing device 3, the sliding member 14 is pressed against the tape cassette 2 and slides in the direction of arrow _X1 .

As the sliding member 14 moves in the direction of arrow _X1 , the bent portions 15a, 16 of the gripping members 15, 16
a is the inclined part 5 from the wide parts 5c ₁ and 5c ₂ of the holder 5.
c ₃ , 5c ₄ , and reach the narrow portions 5c ₅ , 5c ₆ , and are energized by the tensile force of the spring 19 to open the openings 14b ₁ , 14b ₂
They fit into the elongated holes 5a ₃ and 5b ₁ of the holder 5 and come close to each other.

Therefore, the tape cassette 2 has the upper and lower surfaces of the right front side bent at the bent portions 15a and 16a of the gripping members 15 and 16.
is held between the rubber bands 15b and 16b.

Next, as shown in FIG.
With the displacement in the _X1 direction, the pin _14c1 rotates the rotating arm 20a clockwise, and the cam portion 20b1 of the drive transmission mechanism ₂₀ contacts the contact piece 25a of the motor switch 25, thereby closing the switch 25. switch 25
When the bracket 9 is closed, the drive motor 26 attached to the end of the bracket 9 rotates, and the rotational force of the motor 26 is transmitted to the pulley 20c of the drive transmission mechanism 20 via the pulley 27 and belt 28.

The rotating arm 20a is rotated clockwise by the rotational driving force of the motor 26, which is decelerated through gears of the drive transmission mechanism 20, and moves the sliding member 14 to the insertion completion position shown in FIG. tape cassette 2
moves inside the holder ₅ in the direction of arrow X1 together with the sliding member 14 while being held between the upper and lower surfaces by the gripping members 15 and 16.

The gripping members 15 and 16 are on the tape cassette 2,
Since the lower surface is clamped, the pressing forces by the gripping members 15 and 16 act in opposite directions and cancel each other out.
Therefore, when the tape cassette 2 is moved together with the sliding member 14 to the insertion completion position, the sliding resistance against the bottom plate 5a of the holder 5 is only the weight of the tape cassette 2. Therefore, the pressing force of the abutting member that presses the tape cassette 2 against the holder bottom plate 5a is not added to the sliding resistance as in the prior art, and the tape cassette 2 can be moved smoothly with a relatively small force.

In this way, the tape cassette 2 is attached to the holder 5.
When the lid is pulled in and reaches the insertion completion position, the lid lock release button 2a comes into contact with the contact portion _5d2 and is displaced to the lock release position. Further, the front upper surface of the tape cassette 2 faces the bent portion _5d1 .

Further, when the rotating arm 20a rotates clockwise, the pins 14c ₁ and 14c ₂ of the sliding member 14 move from the horizontal portions 9a ₁ and 9b ₁ of the guide grooves 9a and 9b to the vertical portions 9a ₂ and 14c.
Descend along 9b ₂ .

As shown in FIG. 7, the tape cassette 2 inserted into the holder 5 moves along the guide grooves 9a and 9b with the sliding member 14 until it reaches the mounting position.
Y Descend in ₁ direction.

When the tape cassette 2 descends, the lower edge of the lid 2b comes into contact with the slope 23a of the lid opening locking member 23, and is relatively pushed up, opening the lid 2b, as shown in FIGS. 4 and 5. . Note that when the lid 2b comes into contact with the lid opening locking member 23, since the tape cassette 2 in the holder 5 is held between the gripping members 15 and 16,
The lid 2b can be opened stably as the holder 5 descends.

Further, when the holder 5 reaches the mounting position, the lid 2b is opened, the pin 14c ₂ contacts the end of the vertical portion 9b ₂ of the guide groove 9b, and the cam portion 20b ₂ of the drive transmission mechanism 20 closes the motor switch 25. to stop the motor 26. Further, the holder 5 is locked in the mounting position by engagement of a locking mechanism (not shown) provided in the drive transmission mechanism 20.

Note that when the tape cassette 2 is lowered to the mounting position, a positioning pin (not shown) on the chassis relatively contacts the bottom surface of the tape cassette 2, and the tape cassette 2 is moved away from the bottom surface 5a of the holder 5 and lifted slightly. It is installed in the specified position. However, since the gripping members 15 and 16 are rotatably supported on the sliding member 14 by shafts 17 and 18, respectively, even if the tape cassette 2 is displaced upward within the holder 5 at the mounting position, the gripping members 15 and 16 cannot be held. The members 15 and 16 can each rotate to maintain a state in which the upper and lower surfaces of the tape cassette 2 are held between them.

Therefore, the tape cassette 2 is held by the gripping member 1
5 and 16, and is stably mounted at a predetermined mounting position.

Next, when the eject operation is performed, the motor 26 rotates in the opposite direction to that described above and drives the rotating arm 20a counterclockwise. The sliding member 14 has an L-shaped guide groove 9
It moves upward in the direction of arrow Y ₂ along lines a and 9b to reach the insertion completion position, and further moves horizontally in the direction of arrow X ₂ . When the sliding member 14 is returned to the eject position shown in FIG. 3, the gripping members 15 and 16 slide on the inclined parts 5c ₃ and 5c ₄ from the narrow parts 5c ₅ and 5c ₆ to the wide parts 5c ₁ and 5c. ₂ , the tape cassette 2 is separated from the upper and lower surfaces and the grip is released. Note that the tape cassette 2 is held between the gripping members 15 and 16 and pushed back to a position where the rear end protrudes from the insertion opening 3b.

Also, when ejecting tape cassette 2,
While the tape cassette 2 is moving upward from the loading position to the insertion completion position, the pin 20 of the rotating arm 20a
a ₁ contacts the opening lever 34 and rotates the opening lever 34 clockwise to open the opening/closing lid 21.
Therefore, when the tape cassette 2 is returned from the insertion port 3b, the opening/closing lid 21 is opened and does not interfere with the return operation of the tape cassette 2.

Effects of the Invention As described above, the tape storage case mounting device according to the present invention is linked to the movement of the sliding member sliding along the holder after the tape storage case contacts the abutting portion of the sliding member. Since the pair of gripping members are sandwiched between the upper and lower surfaces of the tape storage case via spring members in a closed state, there is no load resistance when inserting the tape storage case, and the insertion feels good and operation is easy. Moreover, when inserting the tape storage case into the holder, the tape storage case can be inserted without damaging the upper and lower surfaces of the tape storage case using the pair of gripping members.

Furthermore, since the pair of gripping members are not directly fixed to the holder but are rotatably provided on the sliding member, the pair of gripping members have a degree of freedom in the vertical direction, and can be easily attached to the tape storage case. Because it has a simple grip function, no unreasonable force is applied to the tape storage case, and no undesirable force is applied between the holder and the tape storage case, so the tape storage case can be attached to the bottom of the holder. can be placed securely.

Moreover, since the pressing forces that press the upper and lower surfaces of the tape cassette act in opposite directions and cancel each other out, the sliding resistance between the tape cassette and the holder bottom plate is due only to the weight of the tape cassette, and the tape cassette is not pressed against the tape cassette as in the past. Compared to moving the tape cassette into the holder by pressing only the top surface,
Sliding resistance is small, reducing the burden on the gripping member when holding the tape cassette, and it is especially advantageous when inserting the tape cassette into the holder with the short side facing forward, since the insertion movement distance is long. It has the following characteristics.
