Even if the plate thickness is different, it can be mounted in the mounting hole of the same shape, and the leg member mounted on the mounting plate is configured to be easily deformed by the pressure from the outside. The present invention relates to a photointerplater capable of performing attachment / detachment.

(Prior Art) A sensor which is arranged in a sheet conveying path of a copying machine or the like and is used for detecting passage of a sheet is provided by projecting a light emitting portion and a light receiving portion from a main body, and is provided between both members. It forms the optical path. Then, an actuator is arranged so as to cross the optical path, and when the actuator is swung by the paper, an operation of blocking or releasing the optical path is performed so that passage of the paper or the like can be detected.

When the sensor as described above is attached to the paper transport path, the photointerplater is fixed to one mounting plate sandwiching the paper transport path, and the actuator is swingably provided on the other supporting means. The actuator is swung by the paper, the sensor is turned on and off, and the passage of the paper is detected.

The mounting means of the sensor is, for example, Shoukai 60-192461.

In addition to the above-mentioned conventional example, generally, mounting means as shown in FIG. 5 is often used. The fifth
The mounting means of the photointerplater 1a shown in the figure is provided by projecting the front leg member 10 and the rear leg member 15 from the bottom surface 3 of the main body 2, and inserting the two leg members into the insertion holes provided in the mounting plate. I am trying to fix it.

However, when using the mounting means as described above,
When removing the photointerplater from the mounting plate, it is necessary to perform operations such as pushing out the leg members from the back surface of the mounting plate, and work cannot be performed only with the front surface of the mounting plate. There is a problem with sex.

On the other hand, as shown in FIG. 6, a leg member including a front leg member 10 and a rear leg member 15 is arranged on the lower surface of the main body, and a portion contacting the surface of the mounting plate is formed in two steps. The photointerpreter 1b may be used.

Therefore, the photointerplater can be easily fixed. Then, when removing the photointerplater, the locking by the hook member can be released by pressing the side surface of one of the leg members with something like a driver.

(Problems to be Solved by the Invention) However, in the conventional device as described above,
When the plate thickness of the mounting plate is different, it is necessary to change the size of the hole depending on the plate thickness as shown in FIG. 7 or 7a. The size of the holes 6 and 7 and the distance between the two holes are different when the thickness of the mounting plate is 1 mm (Fig. 7) and 1.2 mm (Fig. 7a). Depending on the thickness of the guide plate used for the paper transport path of the machine, it is necessary to strictly set the punching position and the size of the hole.

Therefore, when the thickness of the guide plate is changed, there is a problem that it is necessary to redesign the mounting hole in accordance with the thickness.

Further, in the photointerplater 1b of the conventional example, the bottom surface 3 is used for a thin mounting plate such as the plate thickness t.
Corresponds to, and in the case of a thick plate such as thickness t1, the bottom surface 3a
Are mounted in a state of being pressed against the surface of the mounting plate, and the photointerplater is positioned.

Therefore, since the detection position of the sensor is slightly different depending on the plate thickness, it is necessary to take countermeasures such as changing the support shaft of the actuator correspondingly,
There is also a problem that the mounting of the sensor is troublesome.

(Purpose of the Invention) The present invention solves the above-mentioned drawbacks of the conventionally used apparatus, and fixes the photointerplater at a fixed position without being affected by the thickness of the mounting plate. It is an object of the present invention to provide means for enabling the mounting holes to be formed in the mounting plate with the same size.
