摘要： A digital signal recording and reproducing apparatus comprising a dynamic range compression/expansion apparatus. The compression/expansion apparatus (16) receives a digital signal from, for example, an analog-to-digital converter (II) and compresses the dynamic range of the digital signal and the so compressed digital signal is supplied to a recording signal processing circuit (27) in the recording operation mode, while the apparatus receives a digital signal reproduction output from a recording/reproducing head (29, 30) and expands the dynamic range of the reproduced digital signal and the so expanded digital signal is supplied to, for example, a digital-to-analog converter (12) in the reproducing operation mode. The compression/expansion apparatus includes a circuit for controlling the transient response of the apparatus, that is, for controlling the operation of the compression/expansion of the dynamic range of the digital signal during transient of the digital signal so that recording of the digital signal is performed at a high density with a high quality, without suffering breathing effect, overflow, etc.

摘要： An imaging and recording apparatus for electrically recording an optical image of a subject as an image information signal which facilitates memory access from an external device and prevents image information from being changed. Upon manipulation of a recording trigger switch (5), an image outputted from a camera signal processing circuit (17) at that time is written into a semiconductor memory (12), then subjected to data compression in a data compression circuit (21), and stored in a semiconductor memory (13). It is now assumed that an external device not illustrated is connected to a connector (14) and this external device orders taking in the image of the semiconductor memory (13). If at this time the semiconductor memory (13) is writing an image, a state detection circuit (23) detects the fact and inhibits the external device from taking in the image. Furthermore, while the external device is taking in the image of the semiconductor memory (13), the state detection circuit (23) detects this fact.
Even if the recording trigger switch (5) is manipulated, an AND gate (6) turns off in response to an output of the state detection circuit and inhibits image writing into the semiconductor memory (13).

摘要： A terminal 2 held by the user is provided with a radio transmitter and receiver 3. Electronic money information is transferred via the radio transmitter and receiver 3. By using a portable telephone, it is unnecessary to directly insert an IC card 1 into service supply equipment 17. In addition to the service supply equipment 17, a device 9 for storing electronic money information in a lump is provided. Since the electronic money information is transferred into the device 9 for storing the electronic money information in a lump, it is unnecessary to collect the electronic money information stored in terminals one by one.

摘要： An electronic wallet (31) includes a plurality of operating keys (317) at least having a plurality of numeric and calculation keys, a display part (312) for displaying thereon electronic money information and IC card state information, at least one independent function switch (3191, 3192) in addition to a power switch (318), a plurality of control keys (3500) for operating the electronic money information stored in IC cards (10, 10') and the IC card state information, and a plurality of function keys (3501) having a plurality of function level layers (3502, 3503) having a plurality of tasks, for selecting the plurality of tasks having the respective function level layers. Thereby the electronic wallet can have many functions. Further, a modem unit (321), which is removably mounted to card slots (3151, 3161) of the electronic wallet, is provided with a through opening (3162) to communicate with the card slots and a modular jack (3212) to be connected to a communication line (323). Since a user can insert the IC card into the electronic wallet from the card slots with the modem unit already mounted to the card slots, handling of the electronic wallet is convenient upon transfer of the electronic money through the communication line. In addition, the user can insert the IC card into the electronic wallet which is still connected to the communication line.

摘要： A recording method is provided for a video tape recording apparatus having modes for recording PCM audio signals in a plurality of transmission rates. Index codes (104) for a video signal, which enable a search reproduction and so on, are recorded on a video tape in a constant transmission rate irrespective of the transmission rate of a PCM audio signal to be recorded. Further, an amble pattern (501) at the same frequency as the transmission rate of the PCM audio signal is recorded immediately behind the PCM signal recording area (102). A reproducing apparatus may be provided only with an index detecting circuit (603) corresponding to the constant transmission rate.
