According to the above configuration, when the moving device 1 travels on the traveling route 2, the code number of the first code plate 3 is changed when the first reading means 5 passes the position of the first code plate 3. When the second reading means 6 passes through the position of the second code plate 4 by reading from the read portion 8, the second code plate 4 is read.
Will be read from the part 9 to be read. That is, in any of the reading means 5 and 6, the pair of front and rear reading portions 14a, 14b and 16a, 16b are read timing read portions 12a, 12b and 13a, 13b at both ends of each code plate read portion 8, 9. The code numbers of the code plates 3 and 4 are read from the ON / OFF states of the intermediate reading units 15 and 17 when the two are simultaneously detected. In FIG. 2, the reading timing of the first reading means 5 with respect to the first code plate 3 and the reading timing of the second reading means 6 with respect to the second code plate 4 are shown to be the same, but the actual reading timing is shown. Each is freely set,
It is usually different from each other.

Thus, when the first reading means 5 passes through the position of the second code plate 4, the inside of the reading space of the first reading means 5 (the code plate passing space between the projector 18 and the light receiver 19) is moved to the first position. Two cord plates 4
Do not move relative to each other, so that the first reading means 5 does not malfunction due to the second code plate 4,
When the second reading means 6 passes the position of the first code plate 3, the first code plate 3 relatively moves in the reading space of the second reading means 6.

Specifically, as shown in FIG. 2, for example, the total length of the first code plate 3 including the waist plate portion 21 is determined by the distance L 1 between the pair of front and rear reading timing reading portions 16a and 16b of the second reading means 6. If the length is longer than that, the waist plate portion 21 is divided into front and rear by the cutout window 20 having a length L 2 longer than the interval L 1 . Of course, the length L 3 of each of the front and rear waist plate portions 21 is shorter than the interval L 1 .

With this configuration, when the second reading unit 6 passes the position of the first code plate 3, the waist plate portion 21 of the first code plate 3 relatively moves within the reading space of the second reading unit 6. However, due to the presence of the cutout window 20 in the waist plate portion 21, the pair of front and rear reading timing reading portions 16a and 16b of the second reading means 6 do not simultaneously turn on.
Therefore, even if the intermediate reading unit 17 is turned on and off on both sides of the waist plate portion 21, it is not detected as a code reading signal. That is, there is no possibility that the second reading means 6 will malfunction due to the first code plate 3.

When the installation positions of the first cord plate 3 and the second cord plate 4 are close to each other, as shown in FIG. 4, both cord plates 3 and 4 should be continuously integrated with one plate material. You can also
Further, as shown in FIG. 5, the reading portions 14a, 14b, 15 of the first reading means 5 and the reading portions 16a, 16b, 17 of the second reading means 6 are provided in two stages on one portal frame. Thus, both reading means 5 and 6 can be integrated.

Further, instead of forming the cutout window 20 as described above,
Both ends of the waist plate portion 21 are recessed so that the length of the waist plate portion 21 of the first code plate 3 is shorter than the distance L 1 between the reading timing reading portions 16a and 16b of the second reading means 6. You may form in a constricted shape. In particular, as shown in FIG. 6, the distance L 1 between the reading timing reading units 16a and 16b of the second reading unit 6
Is longer than the entire length (including the waist plate portion 21) L 4 of the first cord plate 3, it is not necessary to perform special processing on the first cord plate 3.

(Operation and Effect of the Invention) As described above, in the code reading device of the present invention, the first code plate (3) and the second code plate (4) are on the same line parallel to the traveling direction of the moving device (1). Despite being arranged above, the second code plate (4) has a protrusion amount (H) from the attachment end (11) to the read portion (9) of the first code plate (3). Is smaller than the protrusion amount (H) from the mounting end (10) to the read portion (8), and has read portions (13a, 13b) for reading timing at both ends of the read portion (8). The second reading means (6) simultaneously faces the read portions (13a, 13b) for reading timing at both ends, separately from the code reading portion (17) for reading the read portion (9) of the second code plate (4). Has a pair of reading timing reading parts (16a, 16b), and the first code plate (3) is a reading part of the second reading means (6). (16a, 16b, 17) has a waist plate portion (21) through which face-to-face passes, and the waist plate portion (21) has a pair of reading timing reading units (16a, 16b) of the second reading means (6) at the same time. Since it does not have a facing surface, the second reading means (6) for reading the read portion (9) of the second code plate (4) having a small protrusion amount has the first code plate (3) having a large protrusion amount. )
When passing through the position (1), the waist plate portion (2) between the attachment end (10) of the first code plate (3) and the read portion (8).
Due to 1), the second reading means (6) does not malfunction.

In other words, in the second reading means (6), the pair of front and rear reading timing reading parts (16a, 16b) are provided on the second code plate (4).
The code is read from the read part (9) of the second code plate (4) when the read timing read parts (13a, 13b) at both ends of the first code plate (3) are read at the same time. The fact that the waist plate portion (21) of the second reading means (6) does not have a surface that the pair of reading timing reading portions (16a, 16b) face at the same time means that the second reading means (6) has the first code plate. When passing the position (3), the code reading action of the second reading means (6) is not performed.

In summary, according to the configuration of the present invention, the first reading means (5) and the second reading means (6) can be arranged in series on the moving device side in the traveling direction, so that the reading device on the moving device side is arranged. It is easy to secure a mounting space, and it is easy to configure the moving device itself in a small size. Of course, since the first code plate (3) and the second code plate (4) are arranged on the same line on the travel route side, it is difficult to restrict the configuration on the travel route side. Moreover, the code reading operation by each reading means (5, 6) can be performed accurately and surely without malfunction.
