In this holding device, a pair of tongue pieces 11 and 11 are provided on the original placing table 10 so as to project therefrom. The tongue pieces 11 and 11 are arranged at a position located at the base end portion of the document placing table 10 with a space between each other, and the tongue pieces 11 and 11 project downward.

As is clear from the figure, slits 11a and 11a are formed in these tongue pieces 11 and 11, respectively. Slit 11a
Are formed in the central portion of the tongue piece 11 in the extending direction, respectively, and open at the tip of the tongue piece 11.

Further, in this holding device, a pair of locking members are provided on the device main body 12.
13,13 are provided. The locking members 13, 13 have a substantially U-shape that opens upward, and the inner walls of the portions 13a, 13a located on both sides of the locking members 13, 13 have engaging pieces (engaging pieces) facing each other. Stops) 13b, 13c are provided so as to project.

One engaging piece 13b has an inclined surface 13b ₁ at the tip, and is shorter than the portion 13a, further the inclined surface 13b ₁
Is arranged at the outermost end of the lower end of the inner wall of the portion 13a, with the side surface 12 of the device main body 12 facing upward.
A recessed groove portion 14b is defined between it and a.

The other engaging piece 13c has a prismatic shape and is arranged over the entire length on the outermost side of the inner wall of the portion 13a, and defines a concave groove portion 14c between the side surface 12a of the device body 12 and the side surface 12a. Is made.

The pair of locking members 13 and 13 are arranged on the housing side surface 12a of the apparatus main body 12 with a space therebetween in a manner such that the one engaging piece 13b is located inward.

The tongue piece 11 is formed integrally with the document placing table 10,
