Patent number 8721209 is assigned to
The following quote was obtained by the news editors from the background information supplied by the inventors: "The invention relates to a printer, and more particularly to a multi-function printer having a door opening structure.
"As the information society arrives, office automatic equipment such as scanners, photocopiers, or printers are disposed in offices, and users may perform secretarial processing operations using these office equipment. It should be noted that when the above plurality of office automatic equipment is simultaneously disposed in the office, a lot of space is consumed. As a result, a multi-function printer (MFP) integrated with functions such as copying, printing, and scanning is developed to resolve the above problem.
"Furthermore, information is gradually entering a cloud computing stage, improving the processing speed and convenience when using information. Cloud computing uses the high computing and large storage capacity of a server group through the internet. This way, cloud computing replaces the original software installed on personal computers, or replaces the action of saving information on a personal hard disk. Instead, multiple actions are performed through the internet, and information is stored on the internet, a large virtual space. In other words, users can use cloud computing to perform multi-function printer operations without the restrictions of time and location."
In addition to the background information obtained for this patent, VerticalNews journalists also obtained the inventor's summary information for this patent: "The invention provides a multi-function printer with an automatic door opening structure.
"An embodiment of the invention provides a multi-function printer including a body, a door, a feeding module, a transmission module, and a cam assembly. The door is assembled to the body and is opened or closed relative to the body. The feeding module and the transmission module are disposed in the body. The feeding module has a driving gear. The transmission module has a first swim arm, and an end of the first swim arm is connected to the driving gear. The cam assembly is movably disposed in the body, and is configured between the door and the transmission module. The cam assembly is in a moving range of the first swim arm, and the door is in a moving range of the cam assembly. When the driving gear rotates in a first direction, the other end of the first swim arm is engaged to the cam assembly, and drives the cam assembly to push the door open.
"In an embodiment of the invention, when the driving gear rotates in a second direction, the other end of the first swim arm is disengaged from the cam assembly. The first direction is opposite to the second direction.
"In an embodiment of the invention, the first swim arm is pivoted to the body, and the transmission module further includes a first gear and a second gear. The first gear is disposed on an end of the first swim arm, and is connected to the driving gear. The second gear is disposed on the other end of the first swim arm, and oscillates with the first swim arm. The cam assembly is located on a moving path of the second gear.
"In an embodiment of the invention, the cam assembly includes a third gear and a cam coaxially disposed. The third gear is located on a moving path of the second gear. The first swim arm oscillates so the second gear is engaged or disengaged with the third gear.
"In an embodiment of the invention, when the second gear is disengaged from the third gear, a protruding portion of the cam will move away from a door closing position of the body due to weight.
"In an embodiment of the invention, the cam assembly includes a fourth gear, a second swim arm, and a cam. The fourth gear is located on a moving path of the second gear. The second swim arm moves so the second gear is engaged or disengaged with the fourth gear. The second swim arm is pivoted to the body. The cam and the fourth gear are respectively disposed on the two opposite ends of the second swim arm, and a protruding portion of the cam faces the door.
"In an embodiment of the invention, the door is pivoted to the body. When the second gear is engaged to the fourth gear, an oscillating direction of the second swim arm is the same as the rotating direction of the door, and an oscillating direction of the first swim arm is opposite to the oscillating direction of the second swim arm.
"Based on the above, in the embodiment of the invention, through the transmission module and the cam assembly disposed between the feeding module and the door, and through the feeding module causing the transmission module and the cam assembly to be engaged or disengaged, the cam assembly can perform the action of pushing the door open. In this way, the user does not need to manually control the multi-function printer, but uses the feeding module actuating the body to make sure the door is open. This allows the multi-function printer to satisfy the functional requirements of cloud equipment.
"In order to make the aforementioned and other features and advantages of the invention more comprehensible, embodiments accompanying figures are described in detail below."
