Embodiment Construction
[0057] Hereinafter, the structure and function of each part of the present invention will be described in detail with reference to the accompanying drawings. In addition, in the following description, the same code|symbol is attached|subjected to the same or corresponding member or structure, and the repeated description is abbreviate|omitted.
[0058] like figure 1 As shown, the lens mounting device of the present invention includes: a base 1 having a lens 5 (see later-described Image 6 (a)) the opening 1a for insertion; the annular frame body 2, which is formed with a cutout part 2a by cutting a part of the outer periphery; the socket 3, which is used for the lens contact 5a as the connecting part with the lens 5 electrical connection; and a first elastic member (eg, a spring) 4 provided to bias the socket 3 from the outer peripheral side of the annular frame body 2 toward the center direction, that is, the radial center. Here, the lens 5 is a projection lens used in a pr...

The invention provides a lens mounting device and a projector. The lens mounting device includes: a base portion having an opening into which a lens is inserted; an annular frame in which a cut-out portion is formed by cutting out a portion of the outer periphery; the socket is used for being electrically connected with the connecting part of the lens; and a first elastic member provided so as to urge the socket from the outer peripheral side of the annular frame toward the center direction, the annular frame being rotatably attached to the base and fixing the lens inserted into the base by rotating a predetermined angle in one direction, and the first elastic member being provided so as to urge the socket toward the center direction from the outer peripheral side of the annular frame when the lens is not fixed by the annular frame. When the lens is fixed by the annular frame body, the notch part is located at a position not facing the socket, when the lens is fixed by the annular frame body, the notch part is located at a position facing the socket, and the socket is electrically connected with the connecting part of the lens under the action of the applying force of the first elastic component. Thus, the lens mounting device can reduce the volume of the socket, suppress poor contact of the socket contacts, and improve the mounting operability of the lens.
Description
technical field [0001] The present invention relates to a lens mounting device and a projector provided with the lens mounting device. Background technique [0002] When attaching a lens to a camera or projector, etc., it is necessary to electrically connect the lens contact on the lens to the socket contact attached to the socket attached to the camera or projector, and to fix the lens to the camera or projector. [0003] Patent Document 1 discloses the following configuration as a lens mounting device as described above. [0004] In Patent Document 1, in order to electrically connect the lens contacts and the socket contacts well and prevent the lens from being erroneously attached to the camera, after the lens is inserted into the camera, the lens is rotated to electrically connect the lens contacts and the socket contacts. connect. [0005] Therefore, the camera of Patent Document 1 has the advantages of small size of the socket and low cost. [0006] However, the abo...
