When a cartridge memory is mounted on a recording medium cartridge such as a magnetic tape cartridge,
Usually, the cartridge memory is appropriately arranged in a space in which the cartridge memory can be arranged according to the internal configuration of the cartridge in consideration of the workability and productivity of assembly as necessary.

However, such a cartridge includes:
Various metal parts such as screws for fixing the upper half and the lower half to assemble the cartridge, and springs (brake springs) for urging the releasing means of the hub brake are arranged. Here, as described above, a non-contact type memory such as a cartridge memory obtains driving power by an electromagnetic induction method, an electrostatic method, or the like, and transmits and receives signals. Therefore, if there is a metal component near the antenna of the non-contact type memory, power supply is not properly performed, malfunction may occur, or signal transmission / reception may be adversely affected, and improper signal transmission / reception may be performed. is there.

Such a problem is solved if all the metal parts used can be made of resin. However, in this method, parts are expensive and the strength is also likely to be reduced mechanically or thermally, and it is very difficult from the viewpoint of both quality and cost of the recording medium cartridge. There was a problem.

When a cartridge memory is mounted to indicate the contents of information recorded on the magnetic tape, the mounting does not hinder the running of the magnetic tape and does not lower the structural rigidity. Therefore, it is necessary to give due consideration to this.

A third problem with the prior art is that some recording medium cartridges for recording data, such as magnetic tape cartridges, are small in size, and because of their structure, the inside of the cartridge is a magnetic tape wound ball. Most of the space is occupied by the space for the erasure prevention mechanism or the mode detection mechanism. Further, nowadays, the winding diameter of the magnetic tape wound ball is increased in order to increase the recording capacity, and the cartridge memory (memory I

This realizes the mounting method.

By the way, in the cassette label shown in the above-mentioned prior art, when the user writes the contents of information recorded on the video tape cassette on the cartridge label, some users may use a ball-point pen. For example, the IC chip (IC memory) of the IC section in the cartridge memory in the cartridge label may be damaged due to high writing pressure.

As a countermeasure against this, JP-A-10-1

Next, a recording medium cartridge according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 3 and FIGS. FIG. 4 shows an example of a lower half of a magnetic tape cartridge as a main part of the recording medium cartridge according to the first embodiment of the present invention. The lower half 12 shown in FIG. 4 is an embodiment in which a non-contact type memory is attached to the lower half of the magnetic tape cartridge shown in FIG. As shown in the drawing, a non-contact type memory (hereinafter, referred to as a cartridge memory) 30, which is a characteristic member of the present invention, is formed in a groove 12h formed on the back side (rear side) of the bottom plate 12a of the lower half 12. , Inserted and retained. In the present invention, the method for holding and positioning the cartridge memory 30 is not particularly limited, and a known method may be used according to the shape, the configuration of the cartridge case, and the like. As described above, the cartridge memory 30 obtains a drive current from the deck-side transmission / reception means using an electromagnetic induction method or an electrostatic method from the deck-side transmission / reception means, and transmits / receives a signal (data). And an IC unit (IC memory) for performing signal processing such as signal storage and signal supply (read / write), and between the signal recording / reading means (signal transmitting / receiving means for the signal) on the deck side. , And transmits and receives information on the cartridge, information on the recorded contents of the cartridge, and the like.

In the illustrated example, the cartridge memory 3
Reference numeral 0 denotes an IC unit 3 composed of an IC memory formed as an IC chip at one end of a substantially rectangular substrate, as shown in FIG.
0a is formed, and a data communication (transmission / reception) antenna unit 30b is formed on the outer edge (outer periphery) of the substrate so as to surround the IC unit 30a
Are formed, and the IC section 30a and the antenna section 30b are integrally formed on one substrate. As described above, the cartridge memory 30 in the illustrated example is a substantially rectangular plate-shaped member, and at least one of the IC units 30a arranged at one end thereof so as to be surrounded by the antenna unit 30b includes:
It is good to be sealed with resin. In addition, the antenna portion 30b disposed on the outer peripheral portion of the portion excluding the IC portion 30a may be sealed with resin. Most preferably, the cartridge memory 30 is entirely sealed with resin. In the present invention, the cartridge memory 30 is not limited to the above configuration and shape. For example, as shown in FIG. 5B, the IC unit 30a and the antenna unit 30b are separate, It may have various configurations or various shapes, such as a configuration in which the antenna portion 30b is formed separately from the substrate on which the IC portion 30a is formed.

As described above, the cartridge memory 30 constructed as described above has no power supply, and is provided when the cartridge 10 containing the cartridge memory 30 is inserted into a recording / reproducing apparatus (deck) (not shown). The cartridge memory 30 operates by an induced current electromagnetically induced by a magnetic field transmitted from an antenna of the data reading / writing device to the data reading / writing device of the recording / reproducing device (deck) and the IC unit 30a. The data is transmitted and received between.

Here, the cartridge 10 according to the present invention
In this case, the cartridge memory 30 is arranged in a region farthest from the metal parts arranged in the cartridge (only the antenna unit can be used if the antenna unit and the IC unit are separate).

As described above, the (non-contact type) cartridge memory 30 uses the electromagnetic induction method or the electrostatic method to
It obtains driving power and transmits and receives signals. Therefore, if a metal component is arranged near the antenna section 30b of the cartridge memory 30, a problem such as a malfunction or an improper signal transmission / reception may occur. On the other hand, in the cartridge 10 (recording medium cartridge) of the present invention, such a cartridge memory 30 (the antenna section 30 thereof) is used.
b) is located in the region furthest away from the metal parts of the cartridge. Therefore, the inconvenience can be solved, and the deck and the cartridge (cartridge memory 3) can be used.
0), stable transmission and reception of appropriate signals can be performed.

FIG. 6 shows the cartridge 10 shown in FIG.
A plan view of the lower half 12 (see FIG. 1) is shown. The main metal components arranged in the illustrated cartridge 10 are a plate spring 26 for urging the slider 20 (indicated by a dotted line in FIG. 6) and four screws for fixing the upper half 11 and the lower half 12. It is. As described above, the leaf spring 26 is fitted between the wall-shaped member 12 e of the lower half 12 and the columnar rib 12 g, and the screw is formed on the overhanging portion 1 formed on the lower half 12.
2c and the screw holes 12i near the left and right ends on the rear side are screwed into corresponding positions of the upper half 11.

The distance from the metal component in the cartridge 10 can be indicated by a circle centered on the metal component. In addition to the above five metal parts, the cartridge 10 includes a spring for urging the front cover 18 and a brake member 2.
Although a brake spring 24 for urging 2 is also included, circles drawn around these are omitted in the cartridge 10 because they are included in the circles corresponding to the above five in the cartridge 10. When a circle (dotted line) having the same diameter is drawn around each metal component (the leaf spring 26 is centered on the rear end), if the diameter of each circle is increased, it is included in each circle until the end. The non-existing area is the lateral center portion on the back side as shown in FIG. That is, in the cartridge 10, this area is an area farthest from the metal component.

Accordingly, as shown in FIG. 6, a circle having the same diameter is drawn around the metal component, and a region not included in the circle is defined as a region farthest from the metal component, as shown in the drawing.
By arranging the cartridge memory 30 in this area, it is possible to transmit and receive appropriate information while minimizing adverse effects due to metal parts. For example, as shown in the illustrated example, in a case where the release means of the brake member 22 (the brake release means of the take-up hub) is a cartridge (magnetic tape) not provided between the take-up hubs 14a and 14b, the rear surface of the cartridge is usually used. The central portion on the side is a region farthest from the metal component, and it is preferable to arrange the cartridge memory 30 in this region.

In the present invention, for example, as shown in FIG. 6, the region farthest from the metal component is included in this circle by drawing a circle of an appropriate size centered on the metal component. It is sufficient if there is no area. The size of the circle is not particularly limited, and may be appropriately determined according to the number and density of the metal parts, the strength of the signal supplied from the deck, the sensitivity of the antenna unit 30b, and the like. Here, in order to preferably transmit and receive signals, as shown in FIG. 6, it is preferable that the diameter of at least the metal parts closest to each other in this plane direction be larger than the diameter of the circle.

Alternatively, as described above, the circle centered on the metal part is increased and the cartridge memory 3
According to the size and shape of 0, the configuration inside the cartridge, etc.
The minimum area where the cartridge memory 30 (the antenna section) can be arranged without being included in the circle may be found, and this area may be set as the area farthest from the metal component. Also,
Similarly, the arrangement position of the cartridge memory 30 may be determined by setting the periphery of the circle that has been enlarged to be the region farthest from the metal component with the last included position as the center.

By the way, at present, at least one of the horizontal direction (the above-mentioned front-rear and left-right directions) and the thickness direction (the direction perpendicular to the horizontal direction) such as a digital video cassette and a cassette which can be recorded and reproduced by a β cam system. Although it is different, it can be used on the same deck (magnetic tape)
Cartridges have been put to practical use. That is, cartridges having different sizes of cartridge cases but usable in the same deck have been put to practical use. Also, in many cases, these cartridges commonly use a means for positioning the cartridges horizontally in the deck, which is located on the deck. That is, the reference portion for horizontal positioning in the deck formed on the cartridge is:
Regardless of size, the shape and position are basically the same.

In the case where the present invention is applied to these cartridges, in the case of at least two sizes of cartridges, the above-described conditions are satisfied, and the horizontal positioning reference portion provided on the cartridge is horizontally moved relative to the horizontal positioning reference portion. It is preferable to arrange the cartridge memories 30 so that the positions in the (left and right) directions are substantially the same. For example, in the illustrated example of the cartridge 10, when there is a horizontal reference portion at the position of the screw hole 12 j on the lower surface of the lower half 12, as an example, a line drawn in the front-rear direction from the reference portion using a cassette having a different size The cartridge memory 30 is arranged so that the distance a from the center of the cartridge memory 30 in the horizontal direction is equal. That is, for cartridges of different sizes, the cartridge memory 30 in the deck
The cartridge memory 30 is arranged so that the positions in the horizontal direction are substantially the same.

With such a configuration, when a cartridge is loaded in the deck and information is transmitted and received between the cartridge memory 30 and the recording and reading means of the deck, the recording and reading means arranged in the deck is used. The movement of the (signal transmitting / receiving means) can be eliminated, and the movement of the cartridge (cartridge memory 30) between the deck (cartridge memory 30) and the deck can be prevented by lowering the accuracy of signal transmission / reception, malfunctioning, and increasing the cost of the deck due to this movement. Thus, it is possible to transmit and receive suitable information.

In this embodiment, the positions of the cartridge memories 30 in the cartridges having different sizes do not necessarily need to be aligned in the front-back direction and the vertical direction (thickness direction). As described above, the cartridge memory 30 arranged in the cartridge of the present invention transmits and receives signals without contact. Normally, radio waves for communication and the like are transmitted toward an object to be transmitted and received, and the transmitted direction has a certain effective distance. Therefore, even if the position of the cartridge memory 30 in the deck is different in the front-rear direction, The signal reaches well. Further, in a normal deck, even if cartridges of different sizes are used, the position in the vertical direction does not change significantly. Therefore, in cartridges of different sizes that can be used in the same deck, the position of the cartridge memory 30 (antenna unit) is
If the above-mentioned horizontal positions are substantially the same, they usually fall within the detection range of the recording and reading means of the deck.

As described above, the recording medium cartridge according to the first embodiment of the present invention has been described in detail by taking a magnetic tape cartridge as an example. However, the present invention is not limited to the above-described example and does not depart from the gist of the present invention. Of course, various improvements and changes may be made within the range.

For example, in the above-described recording medium cartridge, the memory is held in the lower half. However, the present invention is not limited to this. The non-contact type memory (the antenna unit) may be held by another member such as the upper half or the front lid, or the memory may be held by a plurality of members. Further, the above example is a magnetic tape cartridge accommodating a pair of winding hubs for winding a magnetic tape in the cartridge, but the present invention is not limited to this.

In addition, there are various magnetic tape cartridges to which the present invention can be applied, and the scope of the present invention includes all cases where the present invention is applied to such a magnetic tape cartridge.

That is, each of the above embodiments is merely an example of the present invention, and it is needless to say that the present invention should not be limited to these.

Next, FIGS. 1 to 3, FIGS. 5 (a), (b),
A recording medium cartridge according to the third embodiment of the present invention will be described with reference to FIGS. Here, as a recording medium cartridge, a magnetic tape cartridge accommodating a magnetic tape wound ball wound around a pair of winding hubs will be described as a representative example, but the present invention is not limited to this. It goes without saying that it can be widely applied to magnetic tape cartridges.

The recording medium cartridge according to the third embodiment of the present invention uses the information recorded on the magnetic tape shown in FIGS. 5A and 5B in the magnetic tape cartridge (cartridge) shown in FIGS.

As described above, it is not sufficiently prevented.

It should be noted here that, in the case of an IC chip, it is necessary to protect it as a continuous area of a predetermined size, whereas in the case of an antenna section, this is a coil-shaped area. Since the area is occupied, it is effective to actively use the inside of the area as a partitioned area.

Here, the cartridge label 10 of this embodiment is used.
23, a cartridge memory 102 embedded therein is used as shown in FIG. 23. For example, an IC unit 104 that performs information storage and signal processing is provided in a label base 110 that constitutes the cartridge label 100. And an antenna 106 for receiving and supplying information and transmitting and receiving information, and a lead 108 for connecting the antenna 106 and the antenna 106 are embedded. The label base 110 is composed of a label body 112 and a double-sided adhesive tape 114 attached to the lower surface (in the drawing).

For example, as shown in FIG. 25A, inside the frame 127, the user is prompted to describe the recording (broadcast) date, title, and the like of the data to be recorded using the video cassette 140. Are described in advance.

In the example shown in FIG. 25B, a number such as the storage number of the video cassette 140 (see FIG. 22) is easily set in the frame 127 of the description column 126 for antenna protection. For this purpose, a seven-segment number forming element for writing numbers is used as a pre-printed number description field. Thus, in the description column 126 for antenna protection,
By actively encouraging the user to enter the description in the frame 127, the inside of the frame 127 in the description column 126 can be effectively used, and the description in the frame 127 can be avoided to protect the antenna. . In the example shown in FIG. 25A, the description field 128 for protecting the lead wire is also provided on the surface of the cartridge label 100 above the lead wire.
Is provided. Description column 128 for protecting this lead wire
In order to protect the lead wire 108,
A frame 129 having substantially the same shape as the lead wire 108 is formed inside a region surrounded by 8. In the description field 128 for protecting the lead wire, similarly to the description field 126 for protecting the antenna, the description area of the user is limited only inside the frame 127, and the user's additional area outside the frame 129 is added. The description is substantially disabled and the lead wire 108 is protected, and the description items such as the title are printed so as to prompt the user to write. The description field 128 for this lead wire protection
However, similar to the description column 126 for antenna protection, the lead wire 108 is covered and protected to cover the lead wire 108.
A frame 129 having a width slightly larger than the line width of the lead wire 108 and substantially the same shape as the lead wire 108 may be formed. As a result, in the description column 128 for protecting the lead wire, the same protection effect and effective use effect as the description column 126 for protecting the antenna can be achieved. In FIGS. 25A and 25B, reference numerals 130, 132, and 134 denote ICs.
It shows a general entry section that has no protection or antenna protection function.

In the cartridge label 100 for a video cassette according to the present embodiment configured as described above, when the user performs writing with a ballpoint pen or the like, the antenna unit 106 as well as the IC unit 104 is used.
, And also for the lead wire 108, the effect that the risk of damage can be avoided can be obtained.

Further, for example, at any time, the video cassette 14 to which the cartridge label 100 is attached is attached.
0 (see FIG. 22) is set in a recording / reproducing device (not shown), and the cartridge memory 102 in the cartridge label 100 and the data reading / reading device of the recording / reproducing device are read / written by the writing / reading means provided in the recording / reproducing device. Data transmission and reception can be performed with the writing device.

As a method of forming an antenna protection description column 126 on the surface of the cartridge label 100 that makes it virtually impossible for the user to write information, and performing antenna part protection display, for example, a method of forming by printing Is the simplest method, but the method of attaching a seal prepared in advance according to the size of the antenna unit is also an effective method in that it can easily cope with changes.

The description column 126 for antenna protection is as follows.
The area inside the loop antenna constituting the antenna section 106, that is, the area inside the frame 127 is preferably integrated with the design indicating that the area is the information writing area. Here, the meaning of being integrated with the design means that the notation of the frame-shaped area covering the loop antenna is combined with or related to the frame around the other area to form one design as a whole. Refers to the situation.

Since the cartridge memory 102, which is a non-contact type memory, is expensive, it is good to consider that it can be reused. For this purpose, for example, the cartridge label 100 is inserted into a slide groove provided in a video cassette 150 as a recording medium cartridge.
A preferred method is shown in which the video cassette 150 is drawn out from the slide groove of the video cassette 150 and inserted and held in another recording medium cartridge after use.

The embodiments described above are merely examples of the present invention, and it is needless to say that the present invention is not limited to these embodiments.
