Problems solved by technology

[0002] During the working process of a general printing device, paper jams may occur due to paper warping, wrinkling or uneven paper path, or the operation stops due to sudden power failure and other reasons, leaving the paper in the machine. Circumstances that require the user to manually remove the paper
In some printers, after the paper is jammed, the paper feeding roller still rotates, which may cause injury to the operator who picks up the jammed paper

Embodiment Construction

[0029] see figure 1 , in a preferred embodiment of the present invention, a printer includes a transport device 100 , a printing device (not shown) and a paper pick-up door 200 . The conveying device 100 is used to turn over the paper printed by the printing device to the other side for printing by the printing device, and the paper picking door can be opened to facilitate the user to take out jammed paper.

[0030] Please also see figure 2 , the paper picking door 200 includes a door panel 201 and a protrusion 202 extending from the door panel 201 , the protrusion 202 is substantially perpendicular to the door panel 201 . In one embodiment, the protrusion 202 is in the shape of a strip.

[0031] The transmission device 100 includes a mounting frame 10 and a pair of paper feeding rollers 20 pivotally mounted on the mounting frame 10 , and the two paper feeding rollers 20 are arranged up and down.

[0032] The installation frame 10 includes two substantially parallel side p...

Abstract

The invention discloses an interlocking device which is installed on a conveying device in a printer. The conveying device comprises a paper conveying roller, a transmission gear set, a first swing gear set and a second swing gear set. The first swing gear set and the second swing gear set can be engaged with the transmission gear set alternately to drive the paper conveying roller to rotate. The interlinking device comprises a base, a sliding plate and a swing part. The base is fixed to the conveying device. The sliding plate is installed on the base in a sliding manner. The swing part is installed on the base in a pivotal manner. The sliding plate can drive the swing part to rotate to position where the swing part abuts against and presses the first swing gear set when sliding, and therefore the first swing gear set can be separated from the transmission gear set. The sliding plate can drive the second swing gear set to rotate while sliding, and therefore the second swing gear set can be separated from the transmission gear set.

Description

technical field [0001] The invention relates to the field of printers, in particular to an interlocking device applied to printers. Background technique [0002] During the working process of a general printing device, paper jams may occur due to paper warping, wrinkling or uneven paper path, or the operation stops due to sudden power failure and other reasons, leaving the paper in the machine. The situation makes it necessary for the user to manually remove the paper. Some printers still rotate the paper feed roller after the paper is jammed, which is easy to cause injury to the operator who removes the jammed paper. Contents of the invention [0003] In view of the above, it is necessary to provide an interlock device with high safety. [0004] An interlocking device installed on a conveying device in a printer, the conveying device includes a paper feed roller, a transmission gear set, a first swinging gear set and a second swinging gear set, the first swinging gear s...
