An oblong hole 7 is formed in the fourth part 26, and a cylindrical first electrical connection is formed in the oblong hole 7. The connector 8 reciprocates along the longitudinal direction of the oval hole 7 without rotating and is fitted in the same way.

Roughly, notches 9.11 are formed on both the left and right sides of the oval hole 7, and the notches 9.11 are formed on both sides of the right side of the notch 9.11 toward the center of the notch 9.1. A pair of front and rear locking protrusions 10.12 are provided in a protruding manner.

Reference numeral 13 denotes a document separator unit, and the document separator unit 13 includes a chute 14 tilted diagonally downward to the left.
A notch 15 is formed in the approximate center of the chute 14, and a polygonal pulley 16 and a cylindrical pulley 17 are loosely fitted into the notch 15, and the pulleys 16 and 17 and the Nicom belt 18 are mounted on the mv. , the same belt] 8, a presser piece and a tart roller 20 are arranged, and a pair of upper and lower delivery rollers 21122 are arranged at the bottom of the unit 14, and a large number of sheets are stacked on the chute 14. The original 3 is separated from the bottom one by one and sent out one by one by the rotation of one of the pulleys 16, 17 and the delivery roller 21, 22 driven by a motor (not shown). Teihe.

Roughly, the lower surface of the document separator unit 13 is removably fitted with the first electrical connection connector 7-).
A second electrical connection connector 23 is attached, and the notch portions 9 are provided on both left and right sides of the second electrical connection connector 23.
- % 11 and the locking groove 1
0.12 and engaging pieces 24 that can be releasably engaged with each other.
．． 25 are formed respectively. 2) Furthermore, the first electrical connection connector 8 is connected to a recording device, a switch, a power supply device, etc. (not shown) in the copying machine, and a second electrical connection connector 23c and a document separator. It is connected to a motor, a detector, etc. (not shown) of the unit 13.

Moreover, a retaining part (not shown) having the same shape as the engaging part pieces 24 and 25 on the lower surface of the document separator unit 13? The provided lid portion (not shown) is formed to have the same dimensions as the bottom surface of the document separator unit 13.

Since the illustrated embodiment is configured as described above, in order to automatically send the document 3 to the copying machine, the document separator unit 13 must be brought close to the recess 26 in the upper right surface 2a of the casing. Place the pieces 24 to 25 at a diagonally upper left position W'3 than the locking protrusion 10.1.2, and connect the second electrical connection core/lid 23 of the unit 13 to the first electrical connection connector of the copying machine casing 1. 8 and push the unit 13 to the right, the engaging piece 24.5 of the unit 13 will be engaged with the locking protrusion 10.12 on the upper surface 2 of the copier body.
