Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to a cassette storage case.

[Prior art and its problems]

The applicant of the present invention has previously proposed a tape cassette whose bottom view, right side view, left side view, and front view are shown in FIGS. 1 to 4. That is, this tape cassette has a frame body consisting of an opaque upper half 1, an opaque lower half 2, and, for example, a transparent front lid 3. A suitable holding mechanism is provided to maintain the state, for example, a holding mechanism consisting of a U-shaped spring 4 and a slide member 5, so that the front lid 3 can be held in the open state and the closed state. It is a rotating lid that can be opened and closed so that its state is maintained naturally. A hole 6 for inserting a supply reel disk of a recording/reproducing device is formed in the lower half 2, and a supply reel 7 having a flange with a diameter larger than the diameter of the hole 6 corresponds to the position of this hole 6. 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 supply reel 7 does not rotate naturally. Moreover, when this tape cassette is installed in a recording/reproducing apparatus, the supply reel disk of the recording/reproducing apparatus fits into the hole 8 of the supply reel 7 through the hole 6, resisting the elastic force of the elastic body. The supply reel 7 is lifted to the upper half 1 side, and the locked state of the supply reel 7 is released.
The supply reel 7 is directly driven and rotated by the driving force of the supply reel disk, and the magnetic tape wound around the supply reel 7 is fed out. Further, a take-up reel 9 is arranged in the lower half 2 in parallel with the supply reel 7 so as to be able to rotate around an axis fixed to the lower half 2. A hole such as the hole 6 for inserting the supply side reel disk is not formed in the lower half of the installation 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, and this gear 11 meshes with another gear, that is, a gear directly driven by the take-up reel disk. The take-up reel 9 is configured to rotate indirectly. Therefore, when a tape cassette is installed in a recording/reproducing device, the take-up reel 9 is directly driven by the take-up reel disk, for example, on a gear.
A notch 12 is formed in the lower half 2 so that the gear 11 of the lower flange can be engaged with it, and a part of the gear 11 is exposed through the notch 12. In addition, the supply reel 7 and the take-up reel 9 are biased toward the lower half 2 by the elastic body attached to the upper half 1, so the lower end surface of the supply reel 7 is connected to the tape cassette. When it is not attached to the recording/reproducing device, it protrudes a little from the outer surface of the lower end of the lower half 2. Further, grooves 13 and 14 are formed in the vertical direction on the side walls of the frame of the tape cassette, 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 a tape cassette configured as described above, in the case of a recording and playback device exclusively for this tape cassette, it must be installed 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/playback device is fitted to the supply reel, so the supply reel is directly aligned in the magnetic tape feeding direction. The take-up reel 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, and the magnetic tape is supplied. Recording and reproduction are performed by traveling along a predetermined travel route from the side reel to the take-up reel. However, there is a type in which a take-up reel is provided inside the tape cassette housing as described above, which has a gear part on the outer periphery of the supply reel and the reel flange, and a part of this gear is exposed from the cassette housing. Currently, there is no desirable cassette storage case for storing tape cassettes. In other words, since the take-up reel of conventional tape cassettes for audio and video tapes does not have the above-mentioned configuration, the cassette storage case for storing such conventional tape cassettes is equipped with this new type of winding reel. No improvements have been made to the reel on the take-off side, and therefore, if a new type of tape cassette like the one mentioned above is stored in a conventional cassette storage case, various inconveniences will occur.
For example, when the take-up reel rotates during storage, the magnetic tape wound on the take-up reel becomes slack, which causes the magnetic tape to run poorly during recording and playback, resulting in a decline in recording and playback characteristics. There are drawbacks such as.

[Means to solve problems]

The present invention has been developed in view of the above-mentioned problems, and has a gear part inside the tape cassette housing on the outer periphery of the supply side reel and reel flange, and a part of this gear is exposed from the cassette housing. This cassette storage case is for storing a tape cassette of the type that is provided with a take-up reel and a gear part of the take-up reel is rotationally driven. When storing a tape cassette, it is composed of a base body having a section and a rotatable cover body having a top surface section and a front surface section, and is equipped with a gear section that transmits the driving force of the recording/reproducing machine to the take-up reel. The present invention provides a cassette storage case in which a latching member for latching onto the gear portion exposed from the tape cassette housing is provided inside the cassette storage case.

【Example】

5, 6, 7, 8, and 9 are perspective, front, and plan views of an embodiment of a cassette storage case according to the present invention for storing, for example, the above-mentioned type of tape cassette. , a bottom view, and an explanatory cross-sectional view taken along the line A-A. In the figure, 30 is the bottom part of the base body of the cassette storage case, 31 is the back part, 32 is the right side part with the front part partially cut away, and 33 is the right side part 32.
Similarly, the front side portion is a left side portion with a portion cut out, and these bottom portion 30, back portion 31, right side portion 32, and left side portion 33 constitute a base main body. Then, place the front lid 3 side of the tape cassette of the type shown in Figures 1 to 4 on the back side 31 of the cassette storage case, and place the lower half 2 side of the tape cassette on the bottom side of the cassette storage case. 3
When placed on the tape cassette, a cylindrical protrusion 34 is inserted into the hole 8 and prevents the supply reel 7 from wobbling on the bottom surface, corresponding to the position of the hole 8 of the supply reel 7 of the tape cassette. It is provided on the section 30.
The protruding portion 34 is provided with a vertical wall 35 having a tapered upper end surface on its outer peripheral side wall, and this vertical wall 35 is connected to a recess formed in the inner wall of the hole 8 of the supply reel 7. It is configured to hang on. 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 is stored in the cassette storage case, the supply reel 7 is prevented from being lifted toward the upper half 1 by the protrusion 34. Further, on the bottom surface portion 30, there is a substantially track-shaped protrusion 3 having a height much lower than the height of the protrusion 34.
6 is formed, and the tape cassette is attached to the bottom part 3.
When the tape cassette is placed on the tape cassette, the lower end surface of the supply reel 7 is suspended in the air, that is, the lower end surface of the supply reel 7 does not come into contact with the upper surface of the bottom surface section 30. . The right side part 32 has a notch in the front side thereof in a substantially step-like shape, and a rotating shaft 37 and a substantially hemispherical convex part 38 are formed on the outer wall of the right side part 32. The inner wall portion of the surface portion 32 has vertical walls 39, 4 extending in the vertical direction approximately near 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 No. 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. The vertical wall 39 of the right side part 32 and the vertical wall 42 of the left side part are designed so that the front lid 3 side of the tape cassette faces the back side of the cassette storage case, and the lower half is placed on the bottom part. When the tape cassette is stored in the correct orientation, the concave grooves 14 and 1
3, and is configured to fit into the vertical walls 40, 41 of the right side portion 32, respectively.
is constructed so as to mesh with the gear 11 of the lower flange of the take-up reel 9 through the notch 12 of the lower half of the tape cassette. In addition, the lower surface of the bottom part 30 has an uneven part 43 at the part where the fingers touch when the cassette storage case is gripped.
is formed to provide an anti-slip effect. The base body of the cassette storage case configured as described above is made of, for example, opaque ABS resin or the like and is molded into a predetermined shape. Reference numeral 50 denotes the upper surface of the cover body of the cassette storage case, 51 the front surface, 52 the right side surface, and 53 the left side surface. The body is made up of On the right side part 52 and left side part 53 of the cover body,
A rotation shaft insertion hole is configured so that the rotation shafts of the right side part 32 and left side part 33 of the base body are inserted to open and close the cover body, and the rotation shaft 37 of the base body is inserted into this hole. It has been arranged. Moreover, the right side part 32 and the left side part 33 of the base body
Corresponding to the approximately hemispherical convex portion 38 formed in the cover body, holes 54,
55 is formed, and when the cover body is in the closed state, the substantially hemispherical convex portion 38 of the base body fits into the holes 54, 55 of the cover body and is locked. In addition, when the cover body is in the half-open state, even if the cover body is not touched, the lower ends of the right side surface portion 52 and the left side surface portion 53 of the cover body form approximately hemispheres formed on the right side surface portion 32 and the left side surface portion 33 of the base body. The tape cassette can be stored in the cassette storage case even in this state, and the cassette storage case containing the tape cassette can be displayed in this half-opened state. . A recess 56 is formed in the front surface part 51 of the cover body at the outer surface of the lower end in the substantially center thereof, and when opening the cover body, a finger is caught in the recess 56, thereby making it easier to open the cover body. Note that this cover body is made of, for example, transparent PMMA resin and molded into a predetermined shape. Note that the formation positions of the rotation shaft 37 of the base body and the hole of the cover body are such that when the rotation shaft 37 of the base body is inserted into the hole of the cover body and the cover body is attached to the base body, the cover body is When fully opened,
The rear end of the upper surface part 50 of the cover body is configured so as to come into contact with the lower end of the rear surface part 31 of the base body, that is, in the state shown in FIG. It can be placed on a flat surface and the opening angle is as large as possible. The cassette storage case configured as described above can hold the supply side reel 7 of the tape cassette to be stored.
Since the protrusion 34 is provided only for the tape cassette, 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 the tape cassette, which will prevent the tape cassette from being inserted incorrectly, and the tape cassette will always be stored correctly. In other words, the front cover 3 of the tape cassette
Since the tape cassette is always stored with its side facing the back of the tape cassette, the magnetic tape inside the tape cassette is safe even when the cover of the cassette storage case is, for example, half-open. Since the lid 3 will not be opened by mistake and the magnetic tape inside the tape cassette will not be pulled out, the safety of the magnetic tape is extremely high. Further, when storing the tape cassette, the supply reel 7 of the tape cassette is attached to the protrusion 3 of the base body.
4, the position of the supply reel 7, which is not disposed on a fixed shaft like the take-up reel 9, is effectively regulated, and the cassette storage case in which the tape cassette is stored is not disturbed. The supply reel 7 will not wobble even if handled by other people. Further, since the protruding portion 34 is provided with a vertical wall 35 like a claw, this vertical wall 35 is attached to the supply side reel 7 when the tape cassette is stored.
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 is 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. Furthermore, since a convex portion 36 having a substantially track shape, for example, is formed on the bottom surface portion 30 of the base body, when the tape cassette is stored, the lower end surface portion of the supply side reel 7 that protrudes slightly from the lower surface of the tape cassette is As if floating in the air, it is not in contact with the upper surface of the bottom surface portion 30 of the base body, and therefore the supply side reel 7 is not lifted toward the upper half 1 side against the elastic force of the elastic body. Since the supply reel 7 is in pressure contact with the lower half 2, the magnetic tape does not become loose even without the rotation prevention effect of the vertical wall 35. Furthermore, since no more force than necessary is applied against the elastic force of the elastic body, the elastic force of the elastic body has a long durability and can be stored for a long time. There is no change in the bullet body over time. In addition, since the cover body is made of transparent material,
For example, if a label is attached to the top and back of a tape cassette, the contents of the label can be recognized from the outside even when the tape cassette is stored in the cassette storage case. This makes organizing the cassette storage case extremely convenient. Further, when the tape cassette is stored, the vertical walls 40, 41 are provided in the cassette storage case, and the vertical walls 40, 41 engage with the gear 11, which is the driving force transmission mechanism for the take-up reel 9 of the tape cassette. 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, these vertical walls 40, 41
Since the upper end portion is tapered to have a thin thickness, the gear 11 meshes smoothly with the vertical wall 41, and the tape cassette can be stored smoothly. Furthermore, the base body of the cassette storage case is not provided with a front part on the front side, and the front parts of the right side part 32 and left side part 33 are partially cut out, making it easy to store and take out tape cassettes. This makes it extremely easy to store and take out the tape cassette by holding both rear sides of the tape cassette, and even when the cover of the cassette storage case is half-open, the tape can be stored and removed easily. 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, rather than moving it from the top side, after the front cover of the tape cassette comes into contact with the back of the cassette storage case,
Since it is only necessary to lower the tape cassette to the bottom, it can be stored extremely smoothly. Also, when storing the tape cassette, the vertical walls 39 and 42 act as position regulating members for the tape cassette.
Since the height of the tape cassette is lower than, for example, the height of the back surface portion 31, the operation of storing the tape cassette 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 in, so the vertical wall 39,
42 can be smoothly inserted into the grooves 14 and 13. Furthermore, since the vertical walls 39 and 42 are provided on the front side of the base body, the position of the tape cassette is effectively regulated by the vertical walls 39 and 42 and the back surface portion 31. Note that the vertical walls 40 and 41, which are hanging members that hang on the gear 11, are provided on the right side portion 32;
This is gear 11 when storing the tape cassette.
It is only necessary to provide it corresponding to the peripheral edge of the base body, for example, it may be provided on the bottom surface of the base body. In addition, the vertical wall that is the hanging member is not only attached to the base body side, but also to the right side part of the cover body, for example, if the right side part of the cover body enters inside the right side part of the base body, or to the right side part of the cover body. It may be configured so that it is provided on the top surface and hooked to the gear of the tape cassette, but when the cover body is closed after the tape cassette is placed on the base body, the vertical wall is hooked to the gear. Therefore, the gear and the vertical wall may not be properly engaged, so it is better to provide the engagement member on the side where the tape cassette is placed when storing the tape cassette, that is, on the base body side.

【effect】

The cassette storage case according to the present invention includes a take-up reel, which has a supply reel and a gear part on the outer periphery of the reel flange, and a part of the gear is exposed from the cassette housing, inside the tape cassette housing. ,
This cassette storage case is for storing a tape cassette of the type in which the gear section of the take-up reel is rotationally driven. When the tape cassette is stored, it is exposed from the tape cassette housing and is equipped with a gear part that transmits the driving force of the recording/reproducing device to the take-up reel. Since a hooking member is provided inside the cassette storage case to be hooked to the gear section, when the tape cassette is stored in the cassette storage case, the driving force of the recording/reproducing machine is transferred to the winding side. The gear that is transmitted to the reel to rotate the take-up reel is used to prevent the take-up reel from rotating, and in particular, the take-up reel is not located near the center, but around the outer periphery of the reel flange. Since the rotation is prevented at , the rotation prevention effect is good, that is, the wobbling of the take-up reel is further reduced, and therefore the magnetic tape wound on the take-up reel is effectively prevented from loosening. The magnetic tape inside the tape cassette is highly protected and safe.Furthermore, since the gear is hooked to the hooking member, the position of the tape cassette itself can be regulated, and there is less wobbling of the tape cassette itself. It has characteristics.
