Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording / reproducing apparatus using a cassette for video, audio or the like. 2. Description of the Related Art Conventionally, a tape cassette used in a video tape deck has a shape as shown in FIG. 6, for example. In FIG. 6, reference numeral 1 denotes a video tape cassette. In the video tape cassette 1, a cassette main body 2 is composed of an upper half 2a and a lower half 2b made of ABS resin or the like. Two reels 3 are arranged in the cassette main body 2, and one end and the other end of a magnetic tape (not shown) are wound around the two reels 3 in a locked state. A front cover 4 is attached to the front surface of the cassette body 2, and the cassette body 2 and the front cover 4 constitute a housing of the tape cassette 1. The front cover 4 pivots upward and opens only when the video tape cassette 1 is mounted in the deck. When the front cover 4 is opened, the magnetic material protected by the front cover 4 is opened. The tape is exposed from the cassette body 2, and the exposed magnetic tape is pulled out and wound around a rotating head drum of a deck to record and reproduce video signals and the like. [0003] By the way, in the case of this type of video tape cassette 1, if the contents recorded in the cassette must be understood without being reproduced, the management of the cassette is difficult. It is inconvenient. However, as a method of performing such a process using a conventional cassette, there has been only a method of directly writing the contents of the contents on a label 5 attached to the upper surface of the cassette body 2 or the like. The work of writing on the label 5 is time-consuming and requires limited space, so that much data could not be written. In order to solve this problem, the present applicant has previously disclosed, for example, Japanese Patent Application No. 60-298306,
A video tape cassette equipped with electronic circuit components capable of storing predetermined signals has been proposed. If a memory element having a large storage capacity is mounted as this electronic circuit component, various data can be stored, and labor for writing data on a label can be omitted. [0005] However, the electronic component circuit mounted on the video tape cassette is connected to a microcomputer or the like on the deck (that is, a recording / reproducing apparatus) through a connection terminal to perform signal writing and reading , and the video tape cassette is operated.

You. An embodiment of the present invention will be described below with reference to FIGS. In FIGS. 1 to 5, parts corresponding to those in FIG. 6 are denoted by the same reference numerals, and detailed description thereof will be omitted. The tape cassette used in the recording / reproducing apparatus of this embodiment is a video tape cassette of the same standard as that of the example shown in FIG. 6, and as shown in FIG. Buried memory element 6. Then, the connection terminal portion 7 is attached to the lower surface 2c of the cassette body 2 near the memory element 6 with the connection terminal portion 7 being exposed. The connection terminal portion 7 has a plurality of contacts 7a, and each of the contacts 7a is electrically connected to a connection pin (not shown) of the memory element 6. The memory element 6 and the connection terminal 7 are formed on the lower surface 2c by using a thin portion.
So that it does not protrude. Here, the lower surface 2c of the cassette body 2 is a surface on the lower half 2b side where the rotary drive shaft insertion hole 3a of the reel 3 is exposed. Otherwise, the configuration is the same as that of the video tape cassette in the example of FIG. The video tape cassette used in the recording / reproducing apparatus of this embodiment is configured as described above, and the operation when the tape cassette is mounted on the recording / reproducing apparatus, that is, the VCR will be described below. The video tape cassette 1 of the present embodiment is mounted on a video tape deck 8 as shown in FIG. 2 to record and reproduce video signals and the like. This videotape deck 8
Is a so-called front loading type having a cassette insertion window 8a on the front side. When the video tape cassette 1 is inserted through the cassette insertion window 8a as shown by an arrow A in FIG. (Not shown) holds the video tape cassette 1. When the cassette holder holds the video tape cassette 1, the cassette holder moves inside the deck 8 as shown by an arrow B by driving by the loading means, and moves the video tape cassette 1 to the vicinity of the rotating drum. The movement indicated by the arrow B is a movement that moves horizontally from the front to the back and then moves down vertically. When the video tape cassette 1 is fixed inside the deck 8 in this manner, the connection terminals 7 of the video tape cassette 1 are connected to the connection terminals on the deck 8 side. That is, at the cassette fixing position of the deck 8, as shown in FIG. 3, a rubber sheet 10 having a conductive film 11 formed on the surface of a substrate 9 is fixed. This conductive film 11
Are formed to correspond to the contacts 7a of the connection terminals 7 of the tape cassette 1, and each conductive film 11 is
2 is connected to a microcomputer 14 for controlling the operation of the deck 8, which will be described later. The connection terminals on the deck 8 are thus constructed, and the video tape cassette 1 is fixed on the rubber sheet 10 so that the deck 8 and the tape cassette 1 are electrically connected. That is, as shown in FIG. 4, when the video tape cassette 1 held by the cassette holder 13 is fixed on the substrate 9, the connection terminals 7 of the video tape cassette 1 are located on the rubber sheet 10, and the rubber sheet 1
The conductive film 11 on the contact 0 and the contact 7a of the connection terminal portion 7 of the video tape cassette 1 come into contact with each other, and become conductive. FIG. 5 shows a circuit configuration connected to the memory element 6 of the tape cassette 1 connected to the deck side in this manner. In FIG. 5, reference numeral 14 denotes a microcomputer for controlling the operation of the deck 8, and the microcomputer 14 is connected to the memory element 6 via the connection terminal as described above. The microcomputer 14 includes a key 15 for giving an operation instruction and the like,
A cassette detection circuit 16 for detecting whether the mounted cassette is capable of recording, a display panel 17 for displaying an operation status, and the like, and a counter 19 for counting the running amount of the tape are connected. In this manner, the microcomputer 14
When a video signal is recorded on the tape cassette 1 mounted on the deck 8, the recording time, channel, and the like designated by the key 15 are stored in the memory element 6 of the tape cassette 1. When the detection circuit 16 detects that the recorded tape has been mounted, the microcomputer 14 reads out the information stored in the memory element 6 and displays the information on the recorded content on the display panel 17 based on the display information. Thus, the operator can select which part to reproduce by operating the key 15. By mounting the memory element 6 on the tape cassette 1 in this manner, recorded data and the like are stored for each tape cassette. For this reason, the tape cassette 1 can be managed based on the stored information, and there is no need to write the recording data or the like on the label on the upper surface of the cassette.
Further, since the memory element can have a large capacity even if it is small and can be mounted on the tape cassette 1, a large amount of data can be stored. In this embodiment, the connection terminal 7 of the memory element 6 of the video tape cassette 1 is connected to the cassette main body 2.
Is provided on the lower surface 2c of the conductive film 11 on the rubber sheet 10 which is the connection terminal portion on the deck 8 side.
The connection state with the connection is kept good. That is, as described above, when the video tape cassette 1 is mounted on the deck 8, the video tape cassette 1 held in the cassette holder is pushed down internally as shown by the arrow B in FIG. The connection terminal portion 7 on the lower surface 2c and the conductive film 11 on the rubber sheet 10 are pressed against each other, so that a good connection state is maintained. Therefore, writing and reading of the information signal to and from the memory element 6 can be performed reliably. In addition, since the press-contact state is maintained by using the force exerted when the video tape cassette 1 is mounted on the deck 8, a special configuration for maintaining a good connection state is not required, and the configuration is simple. . In each of the above embodiments, a tape cassette for video was described, but the present invention can of course be applied to other tape cassettes for audio or the like. Further, the present invention is not limited to the above-described embodiment, and it goes without saying that various other configurations can be adopted without departing from the gist of the present invention. According to the present invention, a recorded recording medium cassette
When the unit is inserted into the recording / playback device,
Information about recorded contents is read from the memory
Processing of the information relating to the read recorded contents.
Can be performed by the recording / reproducing device. For example, storage of memory elements
The microcomputer reads the information and records it on the display panel.
It is now possible to display information about
You.
