Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cassette housing with a memory having, for example, a non-volatile memory in which arbitrary data can be stored.

[0002]

2. Description of the Related Art For example, in a digital video cassette used for digitally recording a video signal, for example, a non-volatile memory is provided in the cassette housing, for example, on a recording medium (magnetic tape) stored in the cassette. 2. Description of the Related Art Data such as a recording date and time of a video signal to be recorded and a recording position on a medium are stored in a memory thereof (see Japanese Patent Application Laid-Open No. 7-161096).

That is, in FIG. 4, for example, a cassette box 41 is provided on a side opposite to a side 42 on which a tape (not shown) drawing-out port is provided, for example, on a bottom side of a surface to which a label 43 is attached. For example, as shown in FIG.
The electrodes 44 are provided. These electrodes 44 are connected to, for example, a non-volatile memory 45 provided in the cassette housing 41.
(Shown by broken lines).

When such a cassette housing 41 is loaded into, for example, a recording / reproducing device (not shown), the above-mentioned electrode 44 comes into contact with a corresponding contact on the recording / reproducing device side, and the recording / reproducing device side Thus, writing and reading of arbitrary data to and from the memory 45 are performed through these electrodes 44. The read data is displayed on, for example, display means (not shown) provided in the recording / reproducing apparatus.

[0005]

However, in such an apparatus, the data stored in the memory 45 is
For example, writing / reading cannot be performed unless it is loaded in a recording / reproducing device or an equivalent device. This is because even if it is only necessary to know the contents stored in the memory 45, it is necessary to start the recording / reproducing device and load the cassette housing 41 one by one.
A great deal of effort is required to know the contents stored in the.

In the invention disclosed in the above-mentioned references, the contents of the memory are read out simply by placing the cassette housing on a so-called cassette tray. It is necessary to start up, take out the cassette housing, and put it on the floor.

The present application has been made in view of the above points, and the problem to be solved is that, in the case of the conventional apparatus, even if it is only necessary to know the contents stored in the memory, for example, This requires labor such as activating the recording / reproducing device.

[0008]

According to the present invention, a display means is provided on a cassette housing, and data stored in a memory is displayed on the display means. The contents stored in the memory can be known only by the cassette casing alone.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the present invention, a display means is provided in a cassette housing with a memory in which an arbitrary recording medium is accommodated, a memory is provided, and arbitrary data can be stored in the memory. Has a function of reading data stored in the memory and displaying the data on the display means.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings.
FIG. 1 is a configuration diagram showing an example of a cassette housing with memory to which the present invention is applied.

In FIG. 1, for example, a cassette housing 1
For example, as shown in the figure, four electrodes are provided on a predetermined portion on the opposite side to the surface 2 on which the tape (not shown) to be drawn out is provided, for example, on the bottom surface side of the surface on which the label 3 is attached. 4
Is provided. These electrodes 4 are connected to, for example, a non-volatile memory 5 (shown by broken lines) provided in the cassette housing 1.

For example, a reflection type liquid crystal display panel 6 is provided on a so-called upper surface of the cassette housing 1 opposite to a side where a reel shaft or the like is inserted when the cassette housing 1 is loaded into a recording / reproducing apparatus, for example. A battery 7 for driving the liquid crystal display panel 6 and the like (shown by broken lines)
Is provided at a predetermined portion of the cassette housing 1.

FIG. 2 is a block diagram showing an internal circuit configuration of an example of the cassette housing with memory to which the present invention is applied.

In FIG. 2, a control means 10 and a signal conversion means 11 are provided between the memory 5 and the liquid crystal display panel 6 described above. Here, the control means 10 controls the reading of data from the memory 5 and controls the display timing for the liquid crystal display panel 6 and the conversion means 11. Conversion means 11
Is, for example, a character generator circuit that converts a character code into a display signal of the character.

For example, a control signal from the control means 10 is supplied to the memory 5, data (for example, a character code) stored in the memory 5 is read, and this data is supplied to the conversion means 11. At the same time, when the display timing of the liquid crystal display panel 6 is supplied to the conversion means 11, the data from the memory 5 is converted into respective display signals at a predetermined timing and supplied to the liquid crystal display panel 6.

Therefore, in this apparatus, a display means is provided on the cassette housing, and the data stored in the memory is displayed on the display means, so that the contents stored in the memory can be known only by the cassette housing alone. it can.

Thus, according to the present invention, even if the user simply wants to know the contents stored in the memory, the conventional apparatus requires labor such as activating the recording / reproducing apparatus. Can easily be solved.

Further, in this apparatus, by using the reflection type liquid crystal display panel 6 as the display means, an auxiliary light source or the like for viewing a display, such as a conventional transmission type liquid crystal display panel, is not required. it can. As a result, power consumption can be reduced, consumption of the battery 7 can be suppressed, a small-capacity battery can be employed, and demand for a reflective liquid crystal display panel can be increased.

In this apparatus, a photovoltaic power generation means (solar battery) 8 can be provided on the upper surface of the cassette housing 1 as shown in FIG.
That is, since this device has low power consumption as described above, it can be driven by the photovoltaic means 8 having a small capacity. Therefore, for example, photovoltaic power generation means 8 can be employed instead of the above-described battery 7, and in this case, the problem of disposal of used batteries can be solved.

According to the cassette housing with memory described above, an arbitrary recording medium is accommodated, and a memory is provided in the cassette housing with memory in which arbitrary data can be stored in this memory. By providing a means for reading out the data stored in the memory and displaying the data on the display means, the contents stored in the memory can be known only by the cassette casing alone.

[0021]

Therefore, according to the first aspect of the present invention, the display means is provided on the cassette housing, and the data stored in the memory is displayed on the display means, so that only the cassette housing alone is stored in the memory. You can know what was done.

According to the present invention, even if the conventional apparatus simply needs to know the contents stored in the memory, it requires labor such as starting the recording / reproducing apparatus. Can easily be solved.
