Problems solved by technology

[0005] Combining the above two known technologies, although it is conceivable to fix the base of the buffer on the spring support seat, when the above structure is adopted, in order to adjust the torque, the spring support seat must be moved in the axial direction, which will make the spring support seat move axially. The gap between the two spring shells changes, so that when the original pressure plate is closed, the problem of the change in the closing angle of the original pressure plate when the buffer arranged in the compression spring starts to work

Embodiment Construction

[0021] Hereinafter, an embodiment in which the hinge device of the present invention is applied to a copying machine will be described in detail with reference to the accompanying drawings.

[0022] In the accompanying drawings, reference numeral 1 is the mounting part installed on the upper end of the body 2 rear of copier or printing machine, and the two side plates 4a, 4a of supporting part 4 are supported by the first hinge pin 3 on the installation part from above-mentioned mounting part 1. The two side plates 1b, 1b erected on both sides of the plate 1a can be rotated.

[0023] The two side plates 6a, 6a of the elevating member 6 are supported by the free ends of the two side plates 4a, 4a of the support member 4 via the second hinge pin 5, and are also rotatable. Like this, the direction of rotation of support member 4 is just opposite to the direction of rotation of elevating member 6, so, mounting member 1, support member 4 and elevating member 6 are mutually supporte...

Abstract

Provided is a hinge device for adjusting torque without changing the closing angle of an original cover plate on which a damper acts. The hinge device is constituted of an attaching member attached to a device main body side, a supporting member for supporting the original cover plate turnably attached to the attaching member through a hinge pin, a compression spring elastically provided between the supporting member side and the attaching member, and the damper which is provided to be housed inside the compression spring and whose base part is attached to either or both of the attaching member side and the free end side of the supporting member so as to rock. In the hinge device, an adjusting plate is attached to the damper so as to move in a shaft direction and the compression spring is elastically provided between the adjusting plate and the supporting member side or the attaching member side.

Description

technical field [0001] The present invention relates to a hinge device suitable for use in the process of opening and closing an original pressing plate in machines such as copiers and printing machines. Background technique [0002] Conventionally, in machines such as copiers and printing machines, a heavy original pressing plate is well known, which is installed inside the automatic original feeding device. As a hinge device for opening and closing a document pressing plate, for example, a device disclosed in JP-A-11-174597 is known. [0003] The hinge device (the opening and closing device of the original pressing plate) of this known structure is made of the following various parts: a mounting part installed on one side of the device main body; The supporting part of the original pressing plate; it can swing to the side of the above-mentioned supporting part and the side of the above-mentioned mounting part, and is supported by a pivot, and can be stretched and contract...
