There is provided an image input apparatus which can quickly and easily move a camera head to a position that the operator intended, can adequately adjust the position of the camera head, can improve operability in the document photographing mode, and is easy to carry. The image input apparatus has a camera head (2) for inputting an image, support members (5, 6) coupled via a plurality of joint portions (4, 11, 12, 15, 16) so as to be able to support the camera head (2), and a base (14) for supporting the proximal end side of the support members (5, 6). When an image is input by the camera head (2), the camera head (2) can be held at a predetermined position and posture by each of the plurality of joint portions (4, 11, 12, 15, 16). A pivot support mechanism arranged between a camera unit and a support portion has a first support member (6) having two opposing projections (107), a second support member (8) arranged between the two projections (107), a pair of clamping members (104) arranged to clamp the two projections (107) between the second support member (8) and themselves, and a torque generation mechanism (102, 104, 105) for generating a torque between the second support member (8), the clamping members (104), and the projections (107). A pivot support mechanism arranged between a support portion and a base has a first support member (112, 113) having two opposing projections, a second support member 111 which is a planar member having a U-shaped section, and has two end portions respectively engaging with the two projections and a coupling portion for coupling these two end portions, and a torque generation mechanism (114, 116, 118, 119) arranged between the first and second support members (111, 112, 113). An opening portion through which the cable extends is formed on the coupling portion. <IMAGE> |
