Detailed Description

For a better understanding of the technical solutions of the present application, embodiments of the present application are described in detail below with reference to the accompanying drawings.

In one embodiment, the present application is described in further detail below by way of specific embodiments and with reference to the accompanying drawings.

For the imaging device with the cover plate on the surface of the device, the imaging device needs to have the functions of opening, closing and hovering around the fixed rotating shaft so as to facilitate the operations of processing paper jam, replacing selenium drum and the like by a user, fig. 1 shows a schematic diagram of the hovering principle of the cover plate of the imaging device in the prior art, when the cover plate 1' is opened, the roller 3' at the tail end of the supporting rod 2' can be driven to roll in the wedge-shaped chute 41' of the guide rail 4', wherein, as the position of the wedge-shaped chute 41' close to the tail end is provided with an elastic shrinkage part with smaller size, damping force can be generated through deformation, the roller 3' at the tail end of the supporting rod 2' can be clamped at the tail end of the wedge-shaped chute 41', and the supporting rod 2' can not slide forwards, so that the cover plate 1' hovers. Until the user applies force to press down the cover plate 1', the driving roller 3 overcomes the deformation damping force and friction force of the wedge-shaped chute 41', and the elastic shrinkage part of the wedge-shaped chute 41 'is pushed to deform and expand, so that the roller 3' can slide to the front end of the wedge-shaped chute 41', and the cover plate 1' is closed. However, this structure is not suitable for a heavy supporting scenario, that is, when the weight of the cover plate 1' and the weight of the related components (such as the control panel or the scanning device) on the surface of the cover plate is too large, the structure of the guide rail 4' is damaged, and the cover plate 1' cannot be reliably supported.

In addition, since the deformation damping force and friction force of the wedge-shaped chute 41 'also need to be overcome during the process of opening the cover plate 1' to be closed, the opening resistance is large. In addition, since the deformation damping force and the friction force cannot be precisely controlled in a quantitative manner, that is, the deformation damping force and the friction force cannot be precisely calculated and controlled, the effects are easily affected by factors such as machining precision and use time, and in order to make the roller 3 'slide more smoothly in the wedge-shaped chute 41', it may be necessary to smear lubricating oil on the roller 3 'and the wedge-shaped chute 41', but the amount of lubricating oil smeared is difficult to precisely control on a production line, and therefore, the situations such as large difference in cover closing experience of a plurality of imaging devices are also easily caused.

In order to solve the technical problem, the embodiment of the present application provides an image forming apparatus including a terminal apparatus having a printer function such as a laser printer, a copier, a facsimile machine, and the like, without limitation.

In addition, the elastic member 4 in the present application may limit the rotation of the stopper 3 by elastic force generated by elastic deformation being stretched or compressed, and is not limited herein. In the specific embodiment shown in fig. 7 to 12, in the process of rotating the stop member 3 between the first position and the second position, the elastic member 4 can be stretched to limit the rotation of the stop member 3.

In order to ensure that the stopper 3 can be held in the second position during the opening process as shown in fig. 7 to 9, the elastic member 4 is still held in the minimum elastic deformation state, i.e., the minimum stretched state, in the second position.

The elastic member 4 may be a tension spring such as a coil spring or a shaped spring, a tension string-like member such as a bungee cord or a silicone cord, or another elastic member or structure, as long as it can function to restrict the rotation of the stopper 3, and is not limited herein.
