た。2. Description of the Related Art Conventionally, as shown in FIG. 4, a pair of guides 2 for restricting side edges of a sheet is provided on a sheet feeding table 1 for setting a sheet such as a document or a recording sheet. The guides 2 can be moved symmetrically with respect to each other in the direction indicated by the arrow depending on the width of the sheet. As shown in FIGS. 5 and 6, the guide actuating device for symmetrically moving the pair of guides 2 is attached to each guide, and the pair of rack members 3 arranged to face each other. A gear 4 which is arranged between the rack members 3 and meshes with the crack members 3, a support shaft 5 formed on the paper feed table 1 so as to rotatably support the gear 4, and an upper surface of the gear 4. Ring-shaped protrusion 4 formed
The plate 6 arranged so as to come into contact with a, the coil spring 7 which is arranged on the outer periphery of the shaft portion 5a at the tip of the support shaft 5, and which applies a pressing force to the plate 6, and the shaft portion 5a for fixing the coil spring 7. It had fixed screws 8 and washers 9 and the like.

16に固定するためのワッシャ付ねじである。A keyhole-shaped detent 16a is formed on the upper portion of the support shaft 16. Reference numeral 17 is a gear holding member composed of a disk-shaped elastic body. The gear holding member 17 has a keyhole-shaped hole 17a fitted in the rotation stopper 16a of the support shaft 16 at the center thereof, and its outer peripheral portion 17b is directed downward as shown in FIG. It has a bent shape. With this configuration, when the gear holding member 17 is attached to the support shaft 16, the gear is held by the outer peripheral portion 17b.
15 can be pressed. Notches 17c are formed in the outer peripheral portion 17b at appropriate intervals to adjust the spring constant of the outer peripheral portion 17b to an appropriate value. 18 is a gear holding member 17 as a spindle
It is a screw with washer for fixing to 16.

The guide 13 and the rack member 14 fixed to the guide 13 are inserted into the rack 12, and the rack members 14 are opposed to each other. Next, the gear 15 is supported by the support shaft 16 so that its teeth 15a mesh with the teeth of the rack member 14.
To fit. Then, the hole 17 formed in the gear holding member 17
After a is fitted to the detent 16a formed on the upper portion of the support shaft 16, the gear holding member 17 is screwed to the support shaft 16 with the washer screw 18.

ということがない。The guide actuating device assembled as described above has the outer peripheral portion 17b of the gear holding member 17 as shown in FIG. 2 and FIG.
Is in a state of holding the gear 15. At this time, the gear holding member
Since 17 is formed of an elastic body, the gear 16 is pressed and held by an appropriate pressing force, and an appropriate restraining force can be applied to the rotation of the gear 15, that is, the movement of the guide 13. Since the gear holding member 17 presses the side surface of the gear 16 over almost the entire area, the gear 15 is always held stably even if a force in the direction of the support shaft 16 is applied to the gear 15 by the operation of the guide. A stable friction braking force can be obtained. Further, since the hole 17a of the gear holding member 17 is fitted into the rotation stopper 16a of the support shaft 16, the gear holding member 17 rotates as the gear 15 rotates, and the pressing force on the gear 15 and, by extension, the gear 15. It does not impair the deterrent to rotation.

Since the gear holding member is provided with the notch for adjusting the pressing force from the outer peripheral portion toward the center, the gear can be stably pressed and held during the guide operation only by the elastic resin gear holding member. At the same time, there is an effect that the height of the parts for holding the gear can be reduced.
