Problems solved by technology

The above functions are all indispensable functions in the cover opening and closing device, but the known cover opening and closing device usually cannot open the cover to more than 90 degrees
On the other hand, as described in Japanese Patent No. 5217002, even if the lid can be opened to more than 90 degrees, it is impossible to control the rotational moment generated around the hinge lever when the opening and closing angle is more than 90 degrees.

Embodiment 2

[0078] Figure 8 and Figure 9 is a schematic diagram of another embodiment of the present invention. In the lid opening and closing device 120 of the second embodiment, the assembly components are made of synthetic resin. Compared with this embodiment, the lid opening and closing device 5 of Embodiment 1 includes a slider case 6, a slider 7, a support element 8, an assembly element 9 and an elastic element 91, but the lid opening and closing device 120 of Embodiment 2 does not There is a slider case 6, so its structure is simpler than that of the lid opening and closing device 5 of the first embodiment.

[0079] The assembly element 121 made of synthetic resin includes a polygonal cylindrical shell portion 121d and assembly plate portions 121e, 121e, wherein the shell portion 121d is composed of a front plate portion 121a, a rear plate portion 121b, and two side plate portions 121c, 121c. The front plate portion 121a and the rear plate portion 121b are integrally formed, a...

Abstract

The invention discloses a cover body opening closing device, which is provided with an assembly element, an elastic element, a supporting element, and a sliding member. The assembly element is disposed on the upper end part of the rear part of the device body along a vertical direction. The elastic element is disposed in the sliding member accommodation part of the assembly element. The supporting element is used to support the cover body, and is rotatably disposed on the upper part of the assembly element by a hinge chain rod. The sliding member is disposed on the upper part of the elastic element in a covered manner, and is capable of sliding upwards and downwards in the sliding member accommodation part. The upper end part of the sliding member is provided with a cam part having a side surface in the shape of a mountain. The cam part is constituted by a rising cam part and a decreasing part. The cover body opening closing device also comprises a first motion part and a second motion part, which are disposed on the supporting element, and abut against the rising cam part and the decreasing cam part according to the rotation angle of the supporting element. The equipment provided by the invention adopts the above mentioned cover body opening closing device.

Description

technical field [0001] The present invention relates to a cover body opening and closing device and equipment equipped with the cover body opening and closing device. The cover body opening and closing device is suitable for use in office machines such as copiers, compound machines or printing machines or machines used in other production equipment (hereinafter Collectively referred to as equipment) to make its cover open and close. Background technique [0002] In the known cover opening and closing device and the office machine using the cover opening and closing device, as described in Japanese Patent No. 4794144, the cover (or original pressing plate) can usually be opened from its closed position to The maximum is about 90 degrees. Within this opening and closing angle range, the cover opening and closing device can control the rotational moment of the cover around the hinge rod, so that the user will not feel the weight of the cover itself during the opening process o...
