Abstract: A zoom-type viewfinder device which has a multi-sectioned viewfinder cam which rotates in connection with the zooming of a photographic zoom lens. The viewfinder cam has a cam, with at least one cam bevel, which is divided into a first cam component and a second cam component. The first cam component and the second cam component are joined to connect the respective cam bevels to form a cam bevel which wraps more than once around of the cylinder of the viewfinder cam. As the viewfinder cam is manufactured in multiple segments, each segment can be removed from its forming die in the longitudinal direction of the viewfinder cam, thereby providing smooth zooming and a blur free viewfinder image. Also, the inclinations of cam bevels, which are formed on the viewfinder cam, can be made more gradual, which reduces the required driving force. Therefore, a more compact motor can be used, resulting in a more compact camera.

Abstract: A camshaft includes a first end journal portion and first, second and third intermediate journal portions respectively. The first end journal portion is supported in a bearing hole in an upper end wall of the cylinder head. The first, second and third intermediate journal portions are supported in three bearing holes in the three intermediate bearing bosses in the cylinder head, respectively. The radii of the four bearing holes and of a camshaft inserting opening in a lower end wall of the cylinder head are in a relationship such that the camshaft inserting opening is the largest radii, and each adjacent bearing hole is progressively smaller in size. The smallest radii bearing hole is for the bearing hole for the first end journal portion. The largest radius of an intake cam and an exhaust cam is smaller than the radii of the intermediate bearing holes. Thus, the camshaft can be smoothly inserted through the camshaft inserting opening and hence, can be easily assembled into the cylinder head.

Outside of the angular range (41) the cam follower rollers (26, 27) are kept in contact with the cam surfaces with a minimal force.
