Problems solved by technology

Therefore, when the fiber optic block is arranged such that the light output end surface substantially coincides with the light receiving surface while avoiding the electrode pads provided on the outer periphery of the light receiving surface, the light output from the fiber optic block cannot be input to the entire light receiving surface. , the effective area of ​​the light-receiving surface becomes smaller
In this way, it is difficult to make the entire light-receiving surface of the solid-state imaging element into an effective area.

Abstract

A fiber optical block 110 having a light outputting end face 112 which is tilted at a predetermined angle theta of an acute angle with respect to the optical axes of optical fibers 113 and a solid-state image pickup device 210 are provided, and the fiber optical block 110 is arranged so that, in terms of a light-receiving surface 212e, the optical axes of the optical fibers 113 are tilted at the predetermined angle theta toward a first side 212a out of four sides 212a-212d. And, in the solid-state image pickup device 210, each of a plurality of electrode pads 211 is provided on two outer peripheral portions 210b and 210d adjacent to the first outer peripheral portion 210a. Thus, an image sensing device which can favorably combine both the electrode pads and connection wires of the solid-state image pickup device and the fiber optical block tilted with respect to the light receiving surface can be realized.

Description

technical field [0001] The invention relates to an image detection device with a fiber optic block. Background technique [0002] As an image detection device that can detect a two-dimensional image (optical image), there is a fiber optic block that has a light output end surface inclined with respect to the optical axis of the optical fiber and a light-receiving surface of a solid-state imaging element that is directly and optically connected. device. Such an image detection device is used, for example, in a fingerprint detector capable of obtaining a high-quality fingerprint image. [0003] Also, as an image detection device that detects a two-dimensional image of light output from a fiber optic block using a solid-state imaging element, for example, there are Japanese Patent Laid-Open No. 7-211877, Japanese Patent Laid-Open No. 7-174947, and Japanese Patent Laid-Open No. 10 - The device disclosed in Publication No. 12851. In such a device,...
