If the document is placed on the document table with the other page protruding outward from the document table, even if you cover the document with the document pressure plate, it will not hold the document in place stably. In order to prevent misalignment of the original, the original pressing plate is further pressed by hand during copying or reading, which is inconvenient.

The other page side Ob is placed on the document table 2 so as to protrude outward from the front side of the device, and the document pressure plate 3 is attached to this document O.
Even if the document is placed in a pressed state by being tilted over, the force F due to the weight of the one page side Ob protruding outward from the document table 2 is acting on the set document, so the document is held down by the document pressure bonding plate 3 that is tilted over. A force Fa is applied to move the document table 2 toward the front side of the device against the force, as shown in FIG. 10(b).
It is easy to naturally shift α until it reaches a stable position like . If such a shift movement α occurs, the document partial range Oa to be copied or read will be shifted by the movement amount α. Furthermore, in the state of (b), the vicinity of the operation panel section 6 is covered with the protruding document section Ob, which deteriorates the operability.

けるにしてもしっかりと押えつけにくい。Therefore, as mentioned above, in such a case, during the copying or reading of the original in state (a), the original pressing plate 3 is further pressed down by hand to prevent the above-mentioned displacement α of the original O. This is to keep it in a protected state, which is not convenient. Particularly in the case of an image forming apparatus with a movable document table, since the document pressure plate also moves together with the document table, it is difficult to firmly press the document pressure plate even if the document pressure plate is pressed by hand.

The object of the present invention is to enable the document to be held in a state in which the original document is held in a fixed state, and to eliminate the deterioration in operability due to the operation panel section being covered by the portion of the document protruding outward from the document table.

This shows a state in which the document O is supported by the document auxiliary support plate 10 serving as a supporting means, so that the document O is placed and set on the document table 2 in a sufficiently stable manner simply by covering the document press plate 3. FIG. 2 shows a state in which the auxiliary document support plate 10 is folded and stored in the insertion part 5a provided on the front plate 5 of the image forming apparatus 1. FIG. 3 is an exploded perspective view of the front plate 5 and the document auxiliary support plate 10. Components common to the device shown in FIG.
The same reference numerals are given to the parts, and repeated explanations are omitted.

The front plate 5 of the image forming apparatus 1 can be rotated around the center and protruded forward from the front plate 5 of the image forming apparatus 1 in an almost horizontal shelf-like manner as shown in FIG. It can be freely converted to a closed position in which it is folded and stored in the insertion part 5a.

ることがなく、操作性の低下が解消される。The auxiliary document support plate 10 becomes an extension plate on the front side of the document table which is substantially flush with the document table 2 in the open position, and its position is determined by the shape of the dowels 11a and the fitting holes 11b of the hinge parts 11, 11, which will be described later. Retained. Since the document portion Ob protruding outward from the document table 2 is supported on the document auxiliary support plate 10 in this open position, the document portion Ob does not sag downward, and therefore the document placed on the document table 2 0
Since the shifting force due to the downward sagging force of the outward protruding portion does not act on the original cover, the document can be held in a sufficiently stable state with only the original cover plate 3 that is tilted over. There is no need to hold it down. The vicinity of the operation panel section 6 is not covered by the drooping of the outwardly protruding portion Ob of the document, thereby eliminating a decrease in operability.
【0018】原稿補助支持板10は不使用時は図2のよ
うにたたみ込んで格納することで邪魔にならない。When the original auxiliary support plate 10 is not in use, it can be folded up and stored as shown in FIG. 2 so that it does not get in the way.

0aをつまんでなされる。The original auxiliary support plate 10 has dowels 11a and fitting holes 11b and 1 on the front plate 5 of the image forming apparatus 1.
It is attached so that it can be rotated freely to open and close around the hinge parts 11 and 11 consisting of the support plate 10, and the opening and closing operations are performed using the handle part 1 of the support plate 10.
This is done by pinching 0a.

手順により支持板10を閉じ込ませることができる。The state displacement of the hinge portion 11 (11a, 11b) when the support plate 10 is opened and closed will be explained with reference to FIG. The dowel 11a is provided with a plane X, and the hole 11b is provided with a plane Y. (a) and (b) are the states in which the support plate 10 is closed,
Since the plane X faces upward, the dowel 11a is rotated in the direction of the arrow A in the upper part of the hole 11b where the plane Y is not present. Then, when the support plate 10 is opened approximately 90 degrees, (c) and (d)
), and since the plane X is in the same direction as the plane Y, the support plate 10 slips down in the direction of arrow B, resulting in the states (e) and (f). In the states (e) and (f), the plane X and the plane Y are in a mating state, so the dowel 11a cannot rotate and is fixed. Therefore, the support plate 10 is fixed in an open position of approximately 90 degrees, and the document portion O protrudes from the document table 2.
Performs the function of supporting b. Conversely, when closing the support plate 10, the support plate 10 can be closed by following the reverse procedure of (e), (f) → (c), (d) → (a), and (b).

A similar effect can be obtained by providing the above-mentioned members. However, in an image forming apparatus with a movable document table, since the protruding portion of the document slides on the document auxiliary support plate, a sheet of low-friction material or the like is placed on the document contacting surface of the support plate 10, or as shown in FIG. A more reliable effect can be obtained by making the surface of the support plate roller-like to reduce frictional resistance.
