An imaging apparatus capable of preventing redeposition of dust on an imaging device to efficiently achieve dust removal. The imaging apparatus includes a driving device vibrating the imaging device, a posture detecting device detecting a posture of the imaging apparatus, and a controller allowing the imaging device to be vibrated on the condition that the detected posture of the imaging apparatus is a predetermined posture to remove dust deposited on the imaging device. For example, the imaging device is vibrated on the condition that the posture of the imaging apparatus is a normal posture. Alternatively, the imaging device is vibrated so long as it is determined that an opening for lens mounting in a body of the apparatus is pointed down and a photographic lens is not mounted.

The lamination apparatus of this invention is furnished with a supporting member for a core roll around which films and so forth are wound. The supporting member is durable and can hold firmly the core roll without slip of the core roll for the shaft. The lamination apparatus is to form lamination layers of laminate film pasted on the surface of the printed matters like computer output media, posters, advertising fliers and so forth. The supporting member for a core roll is comprised of a flexible tubelike a soft vinyl tube with both ends fixed with fittingin the grooves made on the cylindrical surface of the shaftcut in the axial direction which supports a core roll of laminate film, carrier film and so forth.

A power supply system for a camera supplies electrical power to a light measuring circuit, a display circuit and others. During a hold state before the camera turns into a standby state, the power supply system supplies a boosted electrical power intermittently to the light measuring circuit, the display circuit and others, so that photographic information such as shutter speed and aperture value based on the measurement of the light measuring circuit are displayed on a display and power consumption in the hold state can be made small.

Power supply system for a camera

An electromagnetic actuator suitable for use in combination with the mechanisms of cameras and the like. The electromagnetic actuator has a single electromagnet, and first and second armatures disposed opposite to the opposite attracting surfaces of the electromagnet, respectively. The first armature actuates a first operating lever for operating the shutter release mechanism of a camera, and the second armature actuates a second operating lever for operating the diaphragm of the camera. The first armature is separated from the attracting surface and the second armature is in contact with the attracting surface while the electromagnet is not energized. When the electromagnet is energized, the first armature is attracted to the attracting surface to actuate the first operating lever for releasing the shutter. When the electromagnet is de-energized, the second armature is separated from the attracting surface to allow the second operating lever which has been detained by the second armature to be turned for controlling the diaphragm. A control circuit decreases the current energizing the electromagnet after the first and second armatures have been attracted to the corresponding attracting surfaces to save power.

Electromagnetic actuator for cameras and the like

A camera comprises a main switch, a battery, a battery checking circuit, a display device, a timer and a controller. The camera can be operative by the turn ON of the main switch and can not be operative by the turn OFF of the main switch. The battery supplies an electrical power to circuits in the camera. The battery checking circuit checks a state of the battery. The timer counts a predetermined period of time in response to the turn ON of the main switch. The controller controls the display device based on a result of the battery checking circuit to display the state of the battery during the predetermined period of time and turning off a display of the display device if the state of the battery is better for the camera than a predetermined state after a lapse of the predetermined period of time. Thereby, it is easy to see the other display of the camera in the display device.
