摘要:
In an electric power supply device for supplying electric power to an electronic apparatus, while a first power source is in a state of being connectable to a first power supply path which is arranged to supply electric power directly to the electronic apparatus when the first power supply path is connected to the first power source, a second power source becomes unconnectable to a second power supply source which is arranged to supply electric power directly to the electronic apparatus when the second power supply path is connected to the second power source. While the second power source is in a state of being connectable to the second power supply path, the first power source becomes unconnectable to the first power supply path. With its simple and low-cost arrangement, the device not only effectively prevents duplex power feeding from different kinds of power sources and a voltage drop but also excels in operability and safety.

A recording or reproducing apparatus capable of using power sources of different kinds, each having a different characteristic, is provided with a discriminating switch for discriminating the kind of the power source by means of the configuration of the electrodes of the power source and producing a discrimination result. The electrodes of each kind of power source are formed to have a different configuration. The execution or non-execution of an erasing operation is controlled in accordance with the discrimination result. In addition, an auto-shut-off circuit automatically shuts off the operation of the power source if an inoperative state continues for a predetermined time period, and the predetermined time period is set in accordance with the discrimination result.

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 are formed to have a different configuration. A recording or reproducing apparatus is also disclosed which controls the execution or non-execution of an 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.

A solid-state imaging device assembly is disclosed, comprising a solid-state imaging device; a metal member provided with first means for positioning the solid-state imaging device and second means for positioning the assembly on an apparatus utilizing the assembly; and an insulating frame for sealing the solid-state imaging device together with the metal member in a state in which the solid-state imaging device is positioned with respect to the metal member by the first positioning means of the metal member.
摘要:
The present invention concerns with a so-called program-controlled camera where only one different combination of diaphragm aperture and shutter time value is determined based on a different object brightness. Particularly in the program-controlled camera where the object brightness is measured at the full open aperture and then combined with the preset value of film speed to derive a difference between the full open aperture and the effective diaphragm value, in accordance with which the shutter time is controlled while the diaphragm is adjusted to that effective value, a device is provided for carrying out a program shift in automatic response to the full open aperture value of the interchangeable lens used in the camera.
摘要:
An image sensing apparatus has a cut-off characteristic which is changed by a mechanism for rotating a simple optical low-pass filter having a tightly sealed structure about the periphery of the photographic optical path. Light from a lens representing a subject is received and converted by an image sensing unit upon having its high-frequency components attenuated by a suitable cut-off characteristic, which is for obtaining a color natural image, of a stacked member including an optical low-pass filter or birefringence plates constructing an optical low-pass filter. In a case where a monochromatic image is obtained, some or all of the birefringence plates are rotated through a predetermined angle by changeover means such as a transmission member without sacrificing the seal about the periphery of the optical path, thereby changing over the cut-off characteristic of the optical low-pass filter to a cut-off characteristic suitable for obtaining a monochromatic image. The light from the subject is then received and converted by the image sensing unit.
