[Embodiments] In order to further clarify the configuration and operation of the present invention described above, preferred embodiments of the IC card adapter of the present invention will be described below. FIG. 2 is a perspective view showing the external appearance of the IC card adapter 1 and the tape recorder 3 to which it is attached as an example, and FIG. 3 is a block diagram showing the internal configuration of the IC card adapter 1.

As shown in the figure, the IC card adapter 1 of this embodiment is
It has almost the same shape as a cassette tape, and has an I
It has a holder part 12 for storing a C card 10. Also,
The tape recorder 3 has a record button 21, which serves as a normal operation switch. Play button 22. In addition to a fast forward button 241, a rewind button 25, and a stop button 27, there is also a microphone 30 for recording. A polyneme 35 and the like are provided to adjust the volume from the speaker 32 (FIG. 3).

Inside the IC card adapter 1, as shown in FIG. 3, there is a well-known CPU 41. ROM43. The IC is equipped with RAM44, etc. and controls the exchange of information with the IC card.
A card interface 45 and an input/output port 47 that mediates the exchange of signals with the tape recorder 3 are interconnected via a common bus 48 to form an arithmetic and logic operation circuit.

The IC card 10 is connected to the IC card interface 45 via a connector 49.

The input/output port 47 also includes a Hall element 52 that detects the position of the erasing head 51 of the tape recorder 3, an amplifier 57 that outputs a signal to the pickup coil 55, an amplifier 58 that amplifies the signal from the pickup coil 55, and a tape recorder. An encoder 62 is connected to detect the rotation of the pinch roller 60 of No. 3 via the roller 61. Regarding the circuit inside the Tera recorder 3, the recording/playback head 65. Only the recording amplifier 67 and the reproduction amplifier 68 are illustrated in a simplified manner.

On the other hand, on the surface of the IC card]0, there is a display panel 71. Flat keys 73 to 76 are provided.

These flat keys 73 and 74 are used to specify the address of the memory in the C card 10 in a predetermined unit; operating the flat key 73 moves forward one unit, and operating the flat key 74 moves forward one unit. Then change the address. Flat keys 75 and 76F These keys are used to perform other operations, such as setting recording prohibition.

Next, the processing of the IC card adapter 1 of this embodiment will be explained according to the flowchart shown in FIG.
IC card] IC card adapter 1 with ○ attached is
When the tape recorder 3 is set, processing starts from step 100, and first, a signal from the encoder 64 is input (step 100). Next, it is determined whether the pinch roller 60 is rotating at a constant speed based on the signal from the encoder 64 (step 110). When the record button 21 or play button 22 of the tape recorder 3 is operated, the pinch roller 60 is rotating at a constant speed, so in this case it is further determined whether the erasing head 51 has been detected. (Step 120). The erasing head 51 of the tape recorder 3 is made of a permanent magnet, and is advanced toward the IC card adapter 1 only when the record button 2 is pressed. , it is easy to detect the position of the erasing head 51.

If the erasing head 51 is detected, it is assumed that the tape recorder 3 is recording, and the signal from the pickup coil 55 is sent to the amplifier 58.in accordance with the signal from the encoder 64.
It is read through the input/output port 47, converted into digital information, and written to the IC card 10 (step 13).
0). On the other hand, if the erasing head 5] is not detected (step 20), it is assumed that playback is in progress, and the pickup coil 55 input/output port 47. The digital-to-analog converted signal is output via the amplifier 57, and the tape recorder 3 reproduces the signal (step 140). Therefore, during recording, the audio picked up by the microphone 30 of the tape recorder 3 is recorded on the IC card 10 as a digital signal. On the other hand, during playback, audio is output from the speaker 32 of the tape recorder 3.

With the IC card adapter of the present embodiment described above, it is possible to easily record and play back audio using the conventional tape recorder 3, and the ability of the IC card 10 can be easily and fully utilized. can. For example, you can use the flat keys 75 and 76 as pitch conversion keys to play back digitally recorded audio with pitch changes, to enable random playback even though it is a tape recorder 3, and even to encrypt and record messages.・Various processes such as making it reproducible are possible.

Next, other embodiments of the present invention will be described.

0, an arithmetic and logic operation circuit 240, amplifiers 257, 258, and an encoder 264 similar to those in the first embodiment are provided.

The video tape 220 loaded from the IC card adapter 201 is transferred to a rotating drum 2 equipped with a recording/playback head 265, similar to a normal video cassette tape.
701=In close contact, the audio head 280 inputs and outputs audio signals and records and plays image information.

In this embodiment, similarly to the first embodiment, image data is digitized and recorded on the IC card 210 via the endless videotape 220, and the IC card 2
10 is reproduced by a video tape recorder using an analog signal. In addition, head group 2
30[i This is to achieve the same effect as winding the video tape 220 diagonally around the rotating drum 270 and input/output image information, and it is continuous in a direction inclined at a predetermined angle with respect to the running direction of the video tape 220. and is considered active.

According to the IC card adapter 201, as in the first embodiment, an IC card can be used in a video tape recorder that has been widely used in the past, and various image processing can be easily realized. For example, it is easy to convert the colors of images captured by a video tape recorder and remove background images.Furthermore,
Based on the form of data recording within the IC card 210, it is possible to perform random reproduction of recorded scenes, time-lapse reproduction, or encryption of image information.
