Problems solved by technology

[0007] However, until now, when disposing (orienting) rod-shaped members such as a rod-shaped lens array in a designated direction, the operator has manually arranged the rod-shaped members such as a rod-shaped lens array in a designated direction, thereby causing low efficiency and increased production costs. And other issues

Embodiment Construction

[0052] Next, a rod lens array detection device according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. First, the configuration of the rod lens array 1 for detecting optical performance by the rod lens array detection device of this embodiment will be described. figure 1 It is a schematic perspective view of the rod lens array 1 .

[0053] like figure 1 As shown, the rod lens array 1 has first and second substrates 2 and 4 and a large number of rod lenses 6 arranged in a row between them. The rod lens 6 is a cylindrical lens made of plastic or glass of a refractive index distribution type. The spaces between the first and second substrates 2 and 4 and the respective rod lenses 6 are filled with an adhesive 8 , and the respective rod lenses 6 are fixed between the first and second substrates 2 and 4 .

[0054] The rod lens array detection device of the present embodiment moves the rod lens array co...

Abstract

To allow bidirectional optical inspection by simple constitution. This rod lens array inspection device of the present invention provided with a light source with a measuring pattern, and a detecting means provided with a line sensor and arranged to be opposed to the light source, and for inspecting optical performance of a rod lens array 1 by passing the rod lens array 1 through a measuring area between the light source and the detecting means to make inspection light from the light source get incident into the rod array lens is provided with conveying means for passing twice times the rod lens array through the measuring area by mounting the rod lens array to measure the optical performance to reciprocate it through the area between the light source and the detecting means, and rotary mechanisms for rotating by 90[deg.] the light source and the detecting means around an optical axis of the inspection light as the center.

Description

technical field [0001] The present invention relates to a rod lens array detection device, more specifically to a rod lens array detection device that makes detection light incident on the rod lens array and detects the optical properties of the rod lens array based on the emitted light. Background technique [0002] A rod lens array in which a plurality of cylindrical rod lenses are arranged in a row between two substrates and integrated to form a rod-shaped member is used in copiers, facsimile machines, scanners, and hand scanners. Optical components for image sensors, or writing devices such as LED typewriters using LEDs (Light Emitting Diodes) as light sources, liquid crystal typewriters using liquid crystal elements, and EL typewriters using EL elements. [0003] Such a rod lens array undergoes various tests before leaving the factory, one of which is the measurement of a modulation transfer function (Modulation Transfer Function: MTF). [0004] In this MTF measurement...
