方の上フレーム2との間に介装されている。The cover opening regulating device 9 has a regulating shaft 2 on the upper frame 2.
A cover lock rod 29 pivotably supported around 8,
a release projecting piece 30 formed on the upper surface of the lower frame 1 and abutting the lower end of the cover lock rod 29 to bring the cover lock rod 29 into an unlocked position when the copying machine main body 4 is closed; and an upper end of the cover lock rod 29 an engaging claw 31 formed in;
An engaged piece 33 is formed on the lower surface of the document cover 6 and has an intervention hole 32 for the engaging claw 31 on the rear side, and the cover lock rod 29 is engaged with the engaged piece 33 of the engaging claw 31. It is composed of a lock spring 34 that biases in the direction. The lock spring 34 is interposed between the lower end of the cover lock rod 29 and the upper frame 2 rearward thereof.

ある。In the above configuration, when the copying machine main body 4 is closed, the document cover 6
When it is closed, it is in the state shown in Figure 1. That is, since the upper end cover abutting piece 24 of the regulating rod 21 of the lock release regulating device 8 comes into contact with the lower surface of the document cover 6, the regulating rod 21 swings around the central axis 20 toward the release side of the locking claw 16 of the frame locking device 7. It's moving. *With the cover opening regulating device 9, since the copying machine main body 4 is closed, the cover locking rod 29
The lower end of the cover abuts against the protruding piece 30 of the lower frame 1, and the cover lock rod 29 is rotated toward the lock release side against the lock spring 34. Therefore, the engaged piece 33 on the side of the document cover 6
and the engagement claw 31 on the cover lock rod 29 side are in a non-engaged state.
次に、第2図の如く、原稿カバー6を開放すると軽、上

規制杆21の上端当接片24は、原稿カバー6の開放に
よりカバー6に当接しなくなり、ばね23によってフレ
ームロック装置7のロック爪16規制方向へ揺動する。Next, as shown in FIG. 2, when the document cover 6 is opened, the cover lock rod 29 of the cover opening regulating device 9 is in the unlocked state when the upper frame 2 is in the closed state, so the document cover 6 can be easily opened. . On the other hand, the upper end abutting piece 24 of the regulating rod 21 of the lock release regulating device 8 no longer contacts the cover 6 due to the opening of the document cover 6, and is swung by the spring 23 in the direction of regulating the lock claw 16 of the frame locking device 7.
そのため、規制杆21の下端押圧片22がロック爪16
の上端に当接し、フレームロツク装置7の把手18を前
方へ引こうとしても、規制杆21およ1ばね23により
規制されているため複写機本体4のロックを解除できず
、複写機本体4を開放できない。Therefore, the lower end pressing piece 22 of the regulating rod 21 is pressed against the lock claw 16.
Even if you try to pull the handle 18 of the frame locking device 7 forward, you cannot unlock the copying machine main body 4 because it is restricted by the regulating rod 21 and the first spring 23, and the copying machine main body 4 cannot be released.
また、第1図の如軽複写機本体4の閉、および原稿カバ

軸3周りに上回動できる。Furthermore, when the handle 18 is pulled forward from the closed state of the light copying machine main body 4 and the closed state of the document cover 6 shown in FIG.
6 is not regulated by the regulating rod 21 of the lock release regulating device 8, so you can easily pull the upper 7 lenim 2 and rotate the a-claw 16 around the pongee 14 to lock the lower frame 1 and the upper frame 2. By releasing this, the upper frame 2 can finally be moved upward around the support shaft 3.

クする。At this time, in the cover opening regulating device 9, the lower end of the cover locking rod 29 is separated from the protruding piece 30 of the lower frame 1 due to the upward movement of the upper frame 2, so that the cover locking rod 29 is moved by the locking bone 34 to the original cover 60. The engaging claw 31 engages the engaged piece 33 to lock the document cover 6.
このように、原稿カバー6は閉じていなければロック解

ーム2上の原稿の飛散も防止できる。In this way, unless the document cover 6 is closed, the copying machine main body 4 cannot be opened by the lock release regulating device 8. Furthermore, if the copying machine main body 4 is open, the document cover 6 will not open due to the cover opening restriction device 9.
There is no need to open the copying machine main body 4 in the open state, the copying machine main body 4 can be prevented from falling down due to the tilt of the center of gravity, and the original on the upper frame 2 can also be prevented from scattering.
なお、本発明は、上記実施例に限定されるものではなく

If you do so, the cover opening regulation device will prevent the document cover from sliding in. Therefore, you will not have to open the copying machine with the document cover open, which will prevent the copying machine from tipping over due to the tilt of the center of gravity. It also has an excellent effect of preventing the scattering of water. ″
