Embodiment Construction

[0044] first embodiment

[0045] the whole frame

[0046] refer to figure 1 9 through 9 explain the electronic camera implemented in the first embodiment of the present invention. figure 1 is a perspective view of a single-lens reflex type camera body 1 and a photographing lens 2 mounted on the camera body 1 of an electronic camera realized in the first embodiment of the present invention. A shutter release button 4 , a CCD 5 constituting an image capturing element, and a control circuit 101 that controls various parts of the camera are placed on the camera body 1 . Reference numeral 301 denotes a photographing optical path through which an object image obtained through the photographing lens 2 is guided to the CCD 5 .

[0047] In the electronic camera implemented in this embodiment, the length of the exposure period is controlled by a so-called electronic shutter that controls the time length for which charges are stored in the CCD 5 according to a control signal provided ...

Abstract

As a shutter release button is pressed down, a front end portion of a sequence drive lever moves toward the rear side and, as a result, a mirror-up lever is caused to rotate to the right by the force applied from a mirror up spring. In this state, a mirror drive end presses a mirror drive pin upward to raise a main mirror. In addition, a shutter drive end comes in contact with a shutter drive boss at a switching lever to push the shutter drive boss upward, thereby pulling the shutter blades downward. During a reset operation, the front end portion moves to the front side causing the mirror-up lever to rotate to the left. The main mirror is thus lowered. Since the switching lever is caused to rotate to the right with the force applied from a switching lever reset spring, the shutter blades are pulled upward to shield an opening.

Description

[0001] Referenced patent application [0002] This application claims priority to the following patent applications, and the disclosures thereof are incorporated by reference: Japanese Patent Application No. 2004-128563 filed on April 23, 2004, and Japanese Patent Application No. 2005 filed on January 27, 2005 Application No.2005-020092. technical field [0003] The present invention relates to an electronic camera which obtains an image signal by forming an image of a subject on a solid-state image capturing element. Background technique [0004] Known in the related art is an electronic camera having a solid-state image capturing element constituted by a CCD, which reads charges stored in the CCD and records the charges thus read out into a recording medium as image information. In such an electronic camera including a special type of CCD such as a frame transfer type CCD or a two-field interlaced readout type CCD, it is necessary for the CCD to perform reading of charges...
