There is provided an image input apparatus which can quickly and easily move a camera head to an intended position, 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, support members coupled via a plurality of joint portions to support the camera head, and a base for supporting the proximal end side of the support members. When an image is input by the camera head, the camera head can be held at a predetermined position and posture by each of the plurality of joint portions. A pivot support mechanism arranged between a camera unit and a support portion has a fist support member having two opposing projections, a second support member arranged between the projections, a pair of clamping members arranged to clamp the projections between the second support member and themselves, and a torque generation mechanism for generating a torque between the second support member, the clamping members, and the projections. A pivot support mechanism arranged between a support portion and a base has a first support member having two opposing projections, a second support member, 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 arranged between the first and second support members. An opening portion through which the cable extends is formed on the coupling portion.

This invention provides an image input apparatus which allows easy positioning between an original and a camera head and can improve operability in a document photographing mode. The apparatus has a camera head arranged at the distal end side of columns coupled via a plurality of joint portions, a signal processing unit incorporated in a base of the apparatus main body that supports the proximal end side of the columns, and a cable which is arranged along the columns and connects the camera head and the signal processing unit. When an image signal is input from the camera head to the signal processing unit, the optical axis direction of the camera head and its angle about the optical axis are adjustable via the joint portions. The camera has a lens portion which allows a rotation operation, and an index that can indicate its rotation state is at an appropriate position on the outer surface of the lens portion. The column is supported by the base via a third joint portion. A signal processing circuit board is arranged between a bottom plate and a weight which are electrically connected to each other. An index indicating the direction of the camera head with respect to the base is arranged at least at the center of the front surface of the base. The apparatus is arranged so that the route of the cable does not interfere with the pivot axes of the respective joint portions.

A method of manufacturing a compound semiconductor device comprises forming a scribed groove extending from an edge of a major surface of a laminated body to an internal region on the first major surface. The laminated body has the first major surface and a second major surface and is formed by crystal growth of a compound semiconductor multilayer film on a substrate. The scribed groove is shallow at the edge and deep in the internal region. The method may further comprise separating the laminated body into first and second portions separated by a separation plane including the scribed groove by applying load to the second major surface of the laminated body.

For a lens barrel that restricts the rectilinear of a lens group using a restricting portion such as a rectilinear key, the light-shielding property for external light, the degree of freedom of design relating to the arrangement of the interlocking section for a cam ring, as well as a change in the relative distance between a front group and a rear group are increased. A lens barrel has a first group (front group) 101 and a second group (rear group) 102 that are movable in the optical axis direction. The first group cam ring 124 is cam-engaged with and held by the holding member (the first group barrel 111) of the first group 101, and the second group cam ring 126 is cam-engaged with and held by the holding member (the second group barrel 112) of the second group 102. The moving cam ring 123 guides the first group cam ring 124 and the second group cam ring 126, and the fixed tube 122 is cam-engaged with the moving cam ring 123 to thereby rotatably support it. The front group and the rear group are cam-engaged with and held by different cam rings. The front group and the rear group are held and guided by the moving cam ring 123.

A compound semiconductor device includes a laminated body including a crystal substrate and a compound semiconductor multilayer film. The laminated body has a major surface, a first side face, a second side face, a third side face, and a fourth side face. The first and the second side faces are opposed to each other, substantially perpendicular to the major surface of the laminated body, made of cleaved surfaces. The third and the fourth side faces are perpendicular to the major surface and to the first and the second side faces, opposed to each other, and made of uncleaved surfaces. A groove is provided on the third side face, and the groove has a depth varied with position as viewed from the major surface, and has ends not reaching the first and second side face.

An image sensing apparatus such as digital still camera and video camera having a protection cover for protecting an image sensing optical system. The cover is openable and closable. The image sensing apparatus comprises a cover driver for driving the protection cover; and a control circuit which determines whether the apparatus is set in a image sensing mode, or in an external control mode in which the apparatus is controlled by an external controller unit. The circuit determines an operation of the cover driver in accordance with a determination result.

A lens barrel includes front, intermediate, and rear barrels that hold front, intermediate and rear lens group, respectively. The relative distances among the barrels vary. The front barrel includes a lens barrier and a barrier actuating member. A barrier drive cam section rotates the barrier actuating member upon relative movement of the barrels. The intermediate barrel includes a first drive source for driving a shutter unit, a second drive source for driving a light amount control unit, and a third drive source for driving the intermediate lens group for image stabilization. The intermediate barrel has a rear lens group clearance section at an outer peripheral portion to avoid interference with a driving mechanism for the rear lens group, and a barrier clearance section adjacent to the first or second drive source in a peripheral portion to avoid interference with the barrier actuating member and the barrier drive cam section.
