Abstract

The objective of the invention is to provide a simply, inexpensively and compactly configured device for measuring the adhesion amount of color toner having a monitor function by simple configurations. This color toner adhesive amount measuring device 10 comprises a frame member 11 made of resin equipped with four recessed sections opened to an upper direction, a pair of conductor parts 13 and 14 exposed so as to be made adjacent to each other on the bottom face of each recessed section of the frame member, one chip-shaped light emitting element 15 and three chip-shaped light receiving elements 16, 17 and 18 mounted at the chip mounting part of one conductor part 13 in each recessed section, and electrically connected to the other conductor part and one cover 12 covering the frame member. The cover is provided with a window part having polarizing films 19a, 19b and 19c corresponding to the light emitting element and the first and second light receiving elements and a reflecting surface 12a' for reflecting the rays of light from the light emitting element to the third light receiving element.

Description

technical field

[0001] The present invention relates to a color toner adhesion measuring device for measuring the adhesion amount of color toner in a transfer type color printer, a color facsimile device, and the like. Background technique

[0002] In the past, this kind of color toner adhesion measurement device, for example, is based on Figure 4 composition shown.

[0003] That is, in Figure 4 Among them, the color toner adhesion measuring device 1 is made up of the following parts: LED (light emitting diode) 2 as the light-emitting part; Be configured in the first beam splitter (beam splitter) 3 in the light-emitting light path of LED 2; The first photodiode 4 and the second photodiode 5 ; and the second beam splitter 6 arranged in the light receiving path of these photodiodes 4 and 5 .

[0004] And, the color toner adhesion amount measuring device 1 is disposed in a light source (lamp house) 1a as a whole, and as shown in FIG. Figure 5 is mounted on a substrate 7 as...
