Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a cassette storage case, and more particularly to a cassette storage case for storing a small tape cassette for a video tape recorder.

[Prior Art and its Problems] It is well known that a standard size tape cassette is generally used in a video tape recorder (VTR), which is a magnetic recording and reproducing device. In recent years, this standard type tape cassette has been used. For example, it is well known that a compact tape cassette has been developed that allows recording and playback while maintaining compatibility with a stationary VTR. The external dimensions of this small tape cassette are about 1/3 of the size of the standard type tape cassette.

This type of small-sized tape cassette is used for recording and playback by being directly attached to a recording/playback device (for example, a portable camera-integrated tape recorder such as a video movie) specifically designed for small-sized tape cassettes. In addition, if this small tape cassette is to be used in a stationary recording and reproducing apparatus that uses a standard type tape cassette, the present applicant has previously filed the application in Japanese Patent Application No. 55-168105 (Japanese Unexamined Patent Publication No. 57-168).
94967) and Japanese Patent Application No. 7566 (1983)
123573), it can be used in the same way as a standard type tape cassette by being housed in a tape cassette adapter that has approximately the same shape as the standard type.

Before explaining the cassette storage case of the present invention for storing a small tape cassette for a video tape recorder, we will first explain the bottom view, left side view, right side view, and front view of the above-mentioned small tape cassette previously proposed by the applicant. The specific configuration will be explained with reference to FIGS. 1 to 4 shown.

In other words, a small tape cassette (hereinafter referred to as a tape cassette) for this video tape recorder.
A has a frame body 13 consisting of an opaque upper half 1, an opaque lower half 2, and, for example, a transparent front lid 3, and the front lid 3 maintains each state in an open state and a closed state. For example, a holding mechanism consisting of a U-shaped spring 4 and a slide member 5 is provided so that the front lid 3 can be held in a horizontal state in an open state and a closed state. It is a rotary opening/closing type lid that is configured so that its state is naturally maintained during the operation.

A hole 6 for inserting a supply reel disk of a recording/reproducing device (not shown) is formed in the bottom surface 2a of the lower half 2, and a flange with a diameter larger than the diameter of the hole 6 is formed in correspondence with the position of this hole 6. supply side reel 7 having
is built-in. The supply reel 7 is pressed and biased toward the lower half 2 by the elastic body attached to the upper half 1, and this pressing pressure causes the supply reel 7 to come into pressure contact with the lower half 2. Therefore, the rotation of the supply reel 7 is suppressed and does not rotate naturally. When this tape cassette is installed in the recording and reproducing apparatus, the front cover 3 is opened by the mechanism of the apparatus, and the supply reel disk of the recording and reproducing apparatus is inserted into the supply reel 7 through the hole 6.
The supply side reel 7 is fitted into the hole 8 of the elastic body, and the supply side reel 7 is lifted toward the upper half 1 side against the elastic force of the elastic body, and the locked state of the supply side reel 7 is released, and the driving force of the supply side reel disk is released. The supply reel 7 is directly driven and rotated by the reel 7, and the magnetic tape wound on the supply reel 7 is fed out.

Further, in the lower half 2, a take-up reel 9 is arranged in parallel with the supply reel 7 so as to be able to rotate around an axis fixed to the lower half 2, and the arrangement of the take-up reel 9 is A hole such as the hole 6 for inserting the supply side reel disk is not formed in the lower half 2 at the position. That is, the take-up reel 9 is not configured such that the supply reel is directly driven by the supply reel disk, but is configured so that the driving force of the take-up reel disk is indirectly driven via, for example, a gear. For example, a gear 11 is formed on the peripheral side of the lower flange 10 of the take-up reel 9,
This gear 11 meshes with another gear, that is, a gear on the device side that is directly driven by the take-up reel disk, so that the take-up reel 9 is rotated by indirect drive. Therefore, when the tape cassette is installed in a recording/reproducing device, the lower half is set so that the gear 11 on the lower flange of the take-up reel 9 can mesh with the gear, for example, which is directly driven by the take-up reel disk. A notch 12 is formed in 2, and a part of the gear 11 is exposed through this notch 12.

Furthermore, since the supply reel 7 and the take-up reel 9 are urged toward the lower half 2 by the elastic body attached to the upper half 1 as described above, the lower end surface of the supply reel 7 The tape cassette protrudes slightly from the outer surface of the lower end of the lower half 2 when no recording/reproducing device is attached.

Further, grooves 13 and 14 are formed in the vertical direction on the side walls of the frame 15 of the tape cassette A, that is, on the left and right side walls on the rear sides of the upper half 1 and the lower half 2.

To perform recording and playback using the tape cassette A configured as described above, in the case of a recording and playback device exclusively for this tape cassette, it is necessary to install it as is, or in the case of other types of recording and playback devices. When the tape cassette is installed in a suitable adapter and the switch is turned on, the supply reel disk of the recording/reproducing device is fitted to the supply reel 7, so the supply reel 7 starts feeding out the magnetic tape. The take-up reel 9 is not directly connected to the take-up reel disk, but is indirectly driven and rotated in the magnetic tape winding direction via a drive force transmission mechanism such as a gear 11. The magnetic tape travels along a predetermined running route from the supply reel 7 to the take-up reel 9, and recording and reproduction are performed.

However, although there are various cassette storage cases up to now, the lower end surface 7 of the supply side reel 7 as described above
Currently, there is no desirable cassette storage case for storing tape cassette A of the type with a protruding letter a.

In other words, in conventional audio or video tape cassettes, the reel on which the magnetic tape is wound does not protrude from the frame of the tape cassette. The case does not have any ingenuity for the reel,
Therefore, storing the new type of tape cassettes mentioned above in such a cassette storage case causes various inconveniences, one of which is that the reel protruding from the cassette storage case may cause problems during storage. A force in the retracting direction of the reel is applied to the elastic body that is pressing the reel to protrude, and as a result, the supply side reel 7
There are drawbacks such as the magnetic tape becoming loose due to floating and losing its rotation-suppressing effect, and the elasticity of the elastic body tending to decrease over time.

[Means for Solving the Problems] The present invention has been made in view of the above-mentioned problems, and includes a tape cassette frame whose top surface is closed, and which is pressed against the inner surface of the frame by elastic means from above. This is a cassette storage case for storing a small tape cassette for a video tape recorder, which is equipped with a supply reel whose rotation is suppressed by the tape cassette frame and whose lower end surface protrudes from the bottom surface of the tape cassette frame and which can move up and down. This cassette storage case has a base body having a side face, a back face, and a bottom face upright with one protrusion that fits only with the supply reel, and a base body that is supported by the base body and has an upper face face and a front face face. the tape cassette frame body placed on the bottom surface of the base body and protruding from the tape cassette frame body placed and housed therein; A small tape cassette for a video tape recorder, characterized in that a protrusion is provided on the bottom surface of the base body to prevent the supply reel of the stored tape cassette from remaining stationary. The present invention provides a cassette storage case.

[Embodiment] Figs. 5, 6, 7, 8 and 9 show a cassette for storing a small tape cassette for a video tape recorder according to the present invention, which stores, for example, the above-mentioned type of tape cassette. Storage case 1

It is a cross-sectional explanatory diagram taken along the line A-A in the figure.

In the figure, 30 is the bottom part of the base body 20 of the cassette storage case B, 31 is the back part, 32 is the right side part with the front side partially cut away, and 33 is the front part like the right side part 32. is the left side part with a partially cut out shape, and these bottom part 30, back part 31,
The base body 20 is constituted by the right side part 32 and the left side part 33.

Then, place the front lid 3 side of the tape cassette A of the type shown in FIGS. When placed on the bottom surface 30 of the tape cassette A, a cylindrical protrusion is inserted into the hole 8 to prevent the supply reel 7 from wobbling, corresponding to the position of the hole 8 of the supply reel 7 of the tape cassette A. A portion 34 is provided on the bottom portion 30. Note that this protrusion 34 has a vertical wall 3 whose upper end surface is tapered on its outer peripheral side wall.
5 is provided, and this vertical wall 35 is configured to be hooked into a recess formed in the inner wall of the hole 8 of the supply reel 7. Further, the protruding height of the protruding portion 34 is configured to be shorter than the depth of the hole 8 of the supply reel 7. That is, when the tape cassette A is stored in the cassette storage case B, the supply reel 7 is prevented from being lifted toward the upper half 1 by the protrusion 34.

Further, a substantially track-shaped annular protrusion (protrusion) 36 is formed on the bottom surface 30 and has a height much lower than the height of the protrusion 34 . When the tape cassette A is placed, the lower end surface 7a of the supply reel 7 of the tape cassette A is suspended in the air, that is, the supply reel 7
The lower end surface portion 7a of the bottom surface portion 30 does not come into contact with the upper surface of the bottom surface portion 30.

The right side portion 32 has a front portion cut out in a substantially step-like shape, and a rotating shaft 37 and a substantially hemispherical convex portion 38 are formed on the outer wall of the right side portion 32. 32, there are vertical walls 39, 4 in the vertical direction approximately in the vicinity of the notch position.
0,41 are formed.

The left side part 33 has the same shape as the right side part 32, and the right side part 3 is formed on the outer wall of the left side part 33.
A similar rotation shaft and a substantially hemispherical convex portion are formed at the same positions as the rotation shaft 37 and the substantially hemispherical convex portion 38 of 2, and the right side portion 3 is formed on the inner wall of the left side portion 33.
A similar vertical wall 42 at the same position as the vertical wall 39 of No. 2
is formed.

In addition, the vertical wall 39 of the right side part 32 and the left side part 33
The vertical wall 42 of the tape cassette A allows the tape cassette to be stored in the correct orientation with the front lid 3 side facing the back side of the cassette storage case B and the lower half placed on the bottom surface. concave groove 1
4 and 13, respectively, and is configured to fit into the vertical wall 4 of the right side portion 32.
0 and 41 are gears 11 on the lower flange of the take-up reel 9 from the notch 12 on the lower half of the tape cassette.
It is configured to mesh with the parts.

In addition, the bottom surface of the bottom part 30 is a cassette storage case B.
There is a concave-convex portion 4 on the part where the fingers touch when gripping the
3 is formed to provide an anti-slip effect. The base body 20 of the cassette storage case constructed as described above is made of, for example, opaque ABS resin or the like and molded into a predetermined shape.

Reference numeral 50 designates the top surface of the cover body 21 of the cassette storage case B, 51 the front surface, 52 the right side surface, and 53 the left side surface.
1. The right side part 52 and the left side part 53 constitute a cover body.

Rotation shaft insertion holes are formed in the right side part 52 and left side part 53 of the cover body 21 so that the rotation shafts of the right side part 32 and left side part 33 of the base body can be inserted and the cover body 21 can be rotated to open and close. The rotation shaft 37 of the base body 20 is inserted through this hole. Further, corresponding to the approximately hemispherical convex portions 38 formed on the right side surface portion 32 and left side surface portion 33 of the base body, the right side surface portion 52 and the left side surface portion 5 of the cover body 21 are
Holes 54 and 55 are formed in the cover body 3, and when the cover body 21 is in the closed state, the approximately hemispherical convex portion 38 of the base body fits into the holes 54 and 55 of the cover body 21, and is locked. ing. Also cover body 2
In the half-open state of 1, even if the cover body is not touched, the lower ends of the right side part 52 and the left side part 53 of the cover body 21 are in contact with the right side part 3 of the base body 20.
2 and the substantially hemispherical convex portion 38 formed on the left side surface portion 33, and this state is maintained.For example, even in this state, the tape cassette A can be stored in the cassette storage case B, and the tape cassette can also be stored in this half-open state. The cassette storage case is now on display.

A recess 56 is formed in the front surface 51 of the cover body 21 at the outer surface of the lower end in the approximate center thereof, and when opening the cover body 21, a finger gets caught in this recess 56, making the opening operation easier. .

Note that this cover body 21 is made of, for example, a transparent material.
It is made by molding it into a predetermined shape using PMMA resin.

Note that the formation positions of the rotation shaft 37 of the base body and the hole of the cover body 21 are similar to the rotation shaft 37 of the base body 20.
When the cover body 21 is attached to the base body 20 by inserting the 31, that is, in the state shown in FIG. It's getting old.

Cassette storage case B configured as above
Since the single protrusion 34 is provided only for the supply reel 7 of the tape cassette A to be stored, even if you try to store the tape cassette with the front lid 3 side facing toward you, it will not be possible to store it. , erroneous insertion of tape cassette A can be prevented, and tape cassette A can always be stored correctly, that is, tape cassette A can always be stored with the front lid 3 side facing the back of the cassette storage case.
Even if the cover body 21 of the cassette storage case is in a half-open state, the magnetic tape in the tape cassette A is safe. In other words, if the front lid 3 of the tape cassette A is opened by mistake, the magnetic tape in the tape cassette A is Since the magnetic tape will not be pulled out, the safety of the magnetic tape is extremely high.

Furthermore, when the tape cassette A is stored, the supply reel 7 is restricted by the protrusion 34 of the base body 20, so the supply reel 7, which is not disposed on a fixed shaft like the take-up reel 9, This positional regulation is effective, and even if the cassette storage case B containing the tape cassette A is handled roughly, the supply reel 7 will not wobble. In addition, the protrusion 34 has a vertical wall 3 like a claw.
5, when the tape cassette A is stored, this vertical wall 35 is connected to the supply side reel 7.
The supply reel 7 rotates, and the magnetic tape wound on the supply reel 7 never loosens. The effect of this vertical wall 35 is that since the supply reel 7 is pressed against the lower half by the elastic body, the supply reel 7 rotates naturally, and the magnetic tape wound on the supply reel 7 It is rare that the magnetic tape becomes loose, but this completely eliminates the possibility of the supply reel 7 rotating at some rhythm and causing the magnetic tape to become loose. Since the tip of the vertical wall 35 is tapered, the hole 8 of the supply reel 7 can easily fit into the vertical wall 35.

In addition, the bottom surface 30 of the base body 21 is formed with, for example, an annular protrusion (projection) 36 in the shape of a track, so that when the tape cassette A is stored, it protrudes slightly from the bottom surface of the tape cassette A. The lower end surface 7a of the supply reel 7 is not in contact with the upper surface of the bottom surface 30 of the base body 20, as if floating in the air, and therefore the supply reel 7 resists the elastic force of the elastic body. The supply reel 7 is moved to the lower half 2 without being lifted to the upper half 1 side.
Since the magnetic tape is in pressure contact with the magnetic tape, rotation is suppressed (prevented), and the magnetic tape is prevented from loosening even if the vertical wall 35 does not have the effect of preventing rotation. Furthermore, when stored, undue force is not applied against the repulsive force of the elastic body, so the durability of the elastic force of the elastic body is extended, and it can be stored for a long time. Even if it is used, there is no change in the elasticity over time.

In addition, since the cover body 21 is made of a transparent material, for example, if a label or the like is pasted on the top and rear surface of the tape cassette, the label can be seen from the outside even when the tape cassette is stored in the cassette storage case. It becomes possible to recognize the contents, and it becomes extremely convenient to organize the cassette storage case in which tape cassettes are stored.

Furthermore, when the tape cassette is stored, the cassette storage case B is provided with vertical walls 40 and 41 that mesh with the gear 11 that is the driving force transmission mechanism for the take-up reel 9 of the tape cassette A. Reference numeral 41 serves as a brake mechanism for the take-up reel 9, which prevents the take-up reel 9 from rotating and prevents the magnetic tape from becoming loose even when wound on the take-up reel 9. In particular, this vertical wall 40,
Since the upper tip of the gear 41 is formed in a tapered shape so that the thickness width is thin, the gear 11 is connected to the vertical wall 41.
The engagement is smooth and the tape cassette can be stored smoothly.

Further, the base body 20 of the cassette storage case B is not provided with a front part on the front side, and a right side part 32 is not provided on the front side.
Since the front part of the left side part 33 is partially cut out, it is possible to store and take out the tape cassette very smoothly.In other words, it is possible to store and take out the tape cassette A by holding both rear sides of the tape cassette A. The work is extremely easy. Furthermore, even when the cover body 21 of the cassette storage case B is in a half-open state, tape cassettes can be easily stored and taken out. For example, tape cassettes can be stored and taken out not only from the top side of the cassette storage case but also from the front side. When storing the tape cassette by moving it from the front side, it is easier to store the tape cassette than by moving it from the upper side.
Tape cassette A on the back of the cassette storage case.
After the front cover 3 of the tape cassette comes into contact with the tape cassette, the tape cassette can be stored extremely smoothly by simply lowering it downward.

Also, when storing the tape cassette, the vertical walls 39, 4 act as position regulating members for the tape cassette.
Since the height of the tape cassette 2 is lower than, for example, the height of the back surface 31, the tape cassette storage operation becomes extremely smooth. That is, when storing a tape cassette, first, the storage position of the tape cassette is approximately determined by the outer surface of the tape cassette and the inner surface of the cassette storage case, and then, during storage, the vertical wall 4 is inserted into the grooves 13 and 14.
2,39 will fit into the vertical wall 39,4
2 can be smoothly inserted into the grooves 14 and 13. Furthermore, the vertical walls 39 and 42 are connected to the base body 2.
0, the tape cassette is effectively regulated in position by the vertical walls 39, 42 and the back surface 31.

Note that the convex portion 36 provided on the bottom surface portion 30 in the above embodiment does not have to be in the shape of a track,
For example, it may be a rectangular protrusion, or it may not be continuous. For example, it may be configured to support the lower surface of a stored tape cassette at several positions. However, the arrangement position of the convex portion 36 is
In order to stably support the tape cassette, it is preferable that the support be provided at a position near the circumferential side of the lower surface of the tape cassette. however,
In either case, the position of the convex portion 36 must not be such that it presses the lower end surface portion 7a of the supply reel 7 of the stored tape cassette A. I have never experienced a situation where the supply reel 7 of the tape rotates and the magnetic tape becomes slack.

[Effects] The cassette storage case for storing a small tape cassette for a video tape recorder according to the present invention has the following effects:
In a tape cassette frame whose top surface is closed, rotation is suppressed by being pressed against the inner surface of the frame by elastic means from above, and the lower end surface protrudes from the bottom surface of the tape cassette frame, allowing vertical movement. A cassette storage case for storing a small tape cassette for a video tape recorder equipped with a supply reel, the cassette storage case having a side part, a back part and one protrusion that fits only with the supply reel. The cover body is made up of a base body having a bottom face part with an upright part, and a rotatable cover body supported by the base body and having a top face part and a front face part, and is placed on the bottom face part of the base body. A protrusion is provided on the bottom surface of the base body so as to avoid contact with the lower end surface of the supply side reel protruding from the tape cassette frame body stored in the tape cassette, and Since the reel is kept stationary, the lower end of the supply reel that protrudes from the tape cassette frame will not be pushed into the frame when the tape cassette is stored, and the reel will not be pushed into the tape cassette frame. The repulsive force of the elastic body that is pushing the reel will not weaken during storage, and the locking effect of the supply reel will not be lost during storage. Since the supply reel is not separated from the tape cassette frame by being lifted up against the magnetic tape, the magnetic tape does not become loose. Further, it is not necessary to provide a special reel rotation prevention mechanism in the cassette storage case, and the tape cassette can be stored and stored in a good manner.
