Problems solved by technology

[0009] However, even with the cable shutter button, it is still difficult to completely prevent the vibration of the tripod, etc. that supports the camera.
Moreover, the cable shutter button itself is inconvenient to carry, and special parts such as a socket for attaching the cable shutter button to the camera are required.

Embodiment Construction

[0045]The camera of the present invention will be described in detail below by describing embodiments with reference to the accompanying drawings.

[0046] Such as figure 1 As shown, the camera is provided with a camera control unit 11, a system power supply 12, a main switch 13, a film drive system 14, a lens drive system 15, an exposure control system 16, a shutter drive system 17, a release switch 18, a mode setting switch 19, a remote control Receiver 20 , hand roll switch (also referred to as MR switch) 21 , back cover switch 22 and remote control device 30 .

[0047] The camera control unit 11 constitutes a camera control device for controlling the operation of the entire camera. The system power supply 12 uses a battery to generate power for operating the entire camera, and the system power supply 12 supplies power DCDC to the camera control unit 11 . The main switch 13 is a switch for turning on / off the power supplied by the system power supply 12 , and supplies a sw...

Abstract

When a release signal RL1 is given from a release switch 18 or a remote control release signal RCS1 is received, in a time exposure mode, a camera control part 11 performs photometry and range-finding and extends a lens. When a release signal RL2 is given or the signal RCS1 is received again, the control part 11 controls a shutter driving system 17 to open a shutter and turns on the power source of the reception part 20. Furthermore, when the signal RL2 is given or a remote control release signal RCS2 is received, the control part 11 closes the shutter and controls to feed the film by one frame by a film driving system 14. The invention is to prevent shake at the time of release operation to start and stop time exposure photographing without using cable release and to save power.

Description

technical field [0001] The present invention relates to an improvement of a camera with a long-time exposure function, especially a camera with a long-time exposure function in which the shutter is opened by a set operation and the shutter is closed by a subsequent set operation. Background technique [0002] In a conventional camera using, for example, a silver salt film, long-time exposure photography in which the amount of supplementary light is insufficient due to long-time exposure is used for photography under low light, that is, photography of a low-brightness subject. In addition to the long-time exposure photography through automatic exposure, this long-time exposure photography also uses the long-time exposure function and shutter function (a mode of camera shutter operation, press the shutter button, and the shutter opens). , leave the button, the shutter closes), and realize long-time exposure photography through manual operation. The above-mentioned long-time e...
