Abstract

PURPOSE:To enable assurance of adequate opening and supporting force with the same parts without exchanging a counter balance by providing plural fulcrums for the counter balance on the upper side and using selectively the fulcrums when the weight in the upper part changes. CONSTITUTION:A counter balance 6 is attached to an upper fulcrum (a) and a lower fulcrum (b) in the upper part 1 which is provided openable and closably with a pivot 4 as a fulcrum. Plural pieces of fulcrums (c)... are provided to the fulcrum (a). The fulcrum (c) is used when an automatic original feeder is mounted in the part 1 and the fulcrum (a) is used when said feeder is not mounted. If the reaction of the balance 6 during opening is designated as P kg, the mount of the supporting force by the balance 6 is PLC'' when the fulcrum (c) is used and PLa'' when the fulcrum (a) is used and since LC''>La'', the holding force at the fulcrum (c) increases. The adequate opening and supporting force is thus obtd. with the same parts even if the weight in the part 1 increases.

があった。(Prior Art) A split-opening type copying machine in which the main body of the ridge copying machine is divided into upper and lower parts, and the upper part can be opened and closed using a pivot stop as a fulcrum, uses a counterbalance to open and close the copying machine. was being carried out. For this reason, when an automatic document feeder or the like is attached to the upper side, a counterbalance release support force corresponding to the weight of the automatic document feeder is required. This was obtained by replacing it with one that has a stronger release support capacity. However, in order to replace the counterbalance every time the weight of the upper side of the copying machine changes, it is necessary to prepare several types of counterbalances with different strengths in advance, which makes parts management difficult. In addition, since the replacement work is an extra work compared to the original work of opening and closing the upper part, there is a drawback that it is time-consuming and unfavorable in terms of work efficiency.

解放支持力を得るようにする。In the figure, the main body of the Wanirotib copying machine is divided into an upper part 1 and a lower part 2, and the upper part on the side where the paper output tray 5 is installed is centered around a pivot 4 provided on the side where the paper feed cassette 3 is installed. 1 is configured to rise upward and open. A counterbalance 6 is used to open the upper part 1 with respect to the lower part 2, and the counterbalance 6 is made of support pins arranged at appropriate positions on the sides of the upper part 1 and the lower part 2. Alternatively, it is fixed by an upper fulcrum a and a lower fulcrum S which are constituted by a support shaft or the like. Among the upper and lower fulcrums a and b, a plurality of fulcrums C... are arranged around the upper fulcrum a, and the upper part 10
It should be used differently in response to changes in the weight of the lid, so that it can provide release support that can accommodate the weight.

That is, in the figure, C in the figure is the upper fulcrum of the counterbalance 6 when the IK automatic document feeder 9 device is installed on the upper side of the copying machine, and a is the upper fulcrum when the automatic document feeder is not installed. L is the product of the lengths of perpendicular lines drawn from the rotation center of the pivot 40 to the line of action of the counterbalance 60 force, and PKp is the reaction force of the counterbalance 6 when the upper side is opened, then the moment arm is Fulcrum a: La' When the upper side is open Fulcrum a: La'' When the upper side is closed Fulcrum C: LC/ When the upper side is open Fulcrum C: LC'' ) is M a - P L2'' when the fulcrum is a, and M c = P L c'' when the fulcrum is C. And since La"('L c", Me - Ma = P
(Lc"-La">0, and by changing the upper fulcrum of the counterbalance 4 from a to C, the holding force is strengthened by that value. - (Effect of the invention) As explained above, the present invention The invention is a copying machine 5, an upper part 1 of the main body.
Even if there is a change in the weight, all you have to do is select the corresponding fulcrums a and C of the counterbalance 6 and change the attachment. Therefore, it has the effect of reducing costs and making parts management easier for the copying machine as a whole.
