摘要:
In the disclosed device, the character of sound formed by a sound generator is varied by placing the sound generator in a chamber and varying the chamber to produce at least two sound modes indicating at least two data. According to one embodiment, an aperture in the chamber is covered with a shield accessible from the outside of the camera housing. According to another embodiment, the resonant frequency of the sound is varied by varying the shape of the chamber. In a third embodiment, the chamber is covered and uncovered by varying the registry of two series arranged apertures to the chamber.
摘要:
An electronic apparatus capable of using power sources of different kinds each having a different characteristic is provided with an apparatus for controlling the operating mode of the electronic apparatus on the basis of the discrimination result provided by a discriminating switch, the discriminating switch being provided for discriminating the kind of a power source by means of the configuration of the electrodes of the power source. The electrodes of each kind of power sources is formed to have a different configuration. A recording or reproducing apparatus is also disclosed which controls the execution or non-execution of erasing operation in accordance with the result of discrimination of the kinds of power sources. In addition, a recording or reproducing apparatus is disclosed which is provided with an auto shut-off circuit for automatically shutting off the operation of a power source if an inoperative state continues for a predetermined time or more and which controls, in accordance with the result of discrimination of the kind of a power source, a set time period which elapses until an auto shut-off operation is started.

摘要:
A recording apparatus which records speech and image signals on a disc and includes a memory for storing the speech signal temporarily therein. It updates the contents of the memory in accordance with a triggering signal to record the speech signal and records the contents of the memory rewritten at the occurrence of the last triggering signal.
摘要:
A method of driving a solid-stage image pickup device of the frame transfer type comprises an image sensing part for generating an electrical signal in response to incident light, a storage part for taking and storing the signal generated in the image sensing part, and means for preventing blooming provided at least near the boundary between these image sensing part and storage part. This driving method comprises the steps of: driving the image sensing part independently of the storage part at an arbitrary time; collecting the generated signal near the boundary; clearing them using the blooming preventing means located therein; thereafter, synchronously driving the image sensing part and the storage part under a predetermined relation, thereby transferring the signal in less than the standard television field interval which has been generated so far in the image sensing part to the storage part and storing it therein.
