Definitions

  • the housing 43 is a box formed of a material having a light shielding property with respect to a wavelength range in which the line sensor 42 can receive light.
  • An incident opening (for example, a slit) 44 that guides the received light beam RL emitted from the optical fiber 37 into the housing 43 is formed on one side surface of the housing 43.
  • the illumination light beam IL directed to the sample surface S and the received light beam RL do not overlap on the exposed surface 23. That is, in addition to the component C (FIG. 8) that overlaps the received light beam RL on the sample surface S in the illumination light beam IL toward the sample surface S, the component outside the component C does not overlap the received light beam RL on the exposed surface 23. . Therefore, according to the second aspect of the colorimetric sensor device 1 according to this embodiment, since the scattered light can be further reduced as compared with the first aspect, the colorimetric accuracy is improved in an environment where paper dust is generated. The decrease can be further suppressed.
  • MAX1 indicates the maximum value of L3 in the first mode.
  • MAX2 indicates the maximum value of L3 in the second mode. Since MAX1 is larger than MAX2, it can be seen that the first mode has a higher degree of freedom in arrangement of the transparent member 19 than the second mode.
  • the image forming apparatus 100 is a production printer, and the printing speed is 100 sheets or more per minute.
  • the image forming apparatus 100 includes an image forming apparatus main body 110, a relay apparatus 120, and a post-processing apparatus 130.
  • the image forming apparatus main body 110 includes an automatic document feeder 111 disposed on the upper side thereof.
  • the document fed by the automatic document feeder 111 is read by a scanner unit (not shown).

Abstract

Selon l'invention, un boîtier (20) a un port d'émission (3) servant d'orifice de sortie par lequel un faisceau de lumière d'éclairage (IL) dirigé sur une surface d'échantillon (S) sort du boîtier (20), et servant également d'orifice d'entrée par lequel un faisceau de lumière d'éclairage (IL) réfléchi par la surface d'échantillon (S) pénètre dans le boîtier (20). Un élément transparent (19) est positionné dans l'orifice d'émission (3), et empêche la poussière, comme que de la poudre de papier (61, 63), de pénétrer dans le boîtier (20). L'élément transparent (19) a une surface exposée (23) exposée à l'extérieur du boîtier (20). L'élément transparent (19) est positionné dans un emplacement dans lequel un composant (C), qui se superpose à un faisceau de lumière incident (RL) sur la surface d'échantillon (S) et qui constitue une partie du faisceau de lumière d'éclairage (IL) dirigé sur la surface du spécimen (S), ne se superpose pas au faisceau de lumière incident (RL) sur la surface exposée (23).
