The present invention relates to a sensing device, which comprises a housing, a support, a grating module, a first roller, a second roller and a control unit. When the medium contacts the second roller member, the second roller member drives the first roller member to move the supporter relative to the housing according to the thickness of the medium, so as to change the distance between the firstroller member and the grating wheel of the grating module with respect to the location of the shell. And when the media drives the second roller member to rotate, the second roller member drives thefirst roller member to drive the grating wheel to rotate. The control unit determines whether the medium travels at a predetermined speed according to a corresponding light sensing signal generated bythe grating module when the grating wheel rotates, thereby reminding the user of the progress of the medium.

The invention discloses a double-sided printer. The printer comprises a housing, paper storage boxes and a printing module, wherein the printing module comprises a printing module I and a printing module II, and the printing module I and the printing module II are oppositely arranged on the two faces of a printing medium. The housing is a cube, and a support is arranged in the housing. A printingplatform, a paper conveying mechanism and a sliding rail are arranged on the support, and the paper storage boxes can slide on the sliding rail, wherein the number of the paper storage boxes is not less than three, and the paper storage boxes are arranged at the lower portion in the housing. The invention has the beneficial effects that double sides of the printing medium can be printed at the same time, the traditional double-sided printing step is simplified, and the double-sided printing time is shortened.

To provide a fixing member, which contains a base, and a polyorganosiloxane layer provided on the base, where the polyoranosiloxane layer contains polyoranosiloxane including a silicon atom bonded to three or four oxygen atoms, and wherein the fixing member is designed to be used in a process for heating a toner image on a recording medium to fix the toner image onto the recording medium.

Disclosed is an automatic stamping machine. The automatic stamping machine comprises a machine frame, a stamp rotating shaft, a rolling rotating shaft, a driving mechanism, an automatic ink adding mechanism, a stamp ink box and a locating locking device. The stamp rotating shaft and the rolling rotating shaft are arranged on the machine frame in parallel in a rotating mode, and the stamp rotating shaft is located below the rolling rotating shaft. At least one rolling stamp is arranged on the stamp rotating shaft, and a rolling printing roller which corresponds to the rolling stamp in position is arranged on the rolling rotating shaft. The driving mechanism is installed on the machine frame and drives the stamp rotating shaft and the rolling rotating shaft to synchronously rotate in the opposite directions. The automatic ink adding mechanism automatically adds ink to the stamp ink box. First rolling wheel printing cotton which makes flexible contact with the rolling stamp is arranged in the stamp ink box. The machine frame and a printer are located and locked through the locating locking device. According to the automatic stamping machine, the relative position between the automatic stamping machine and the printer is accurately guaranteed through the innovative locating locking device, the probability of paper jams is reduced, and the stability and the reliability are improved. The first rolling wheel printing cotton makes flexible contact with the rolling stamp, and the service life is long. The automatic ink adding mechanism can achieve automatic and continuous ink addition.

The invention relates to a paper pressing device which comprises a front cover and a rear cover which can be mutually fastened with the front cover, wherein the front cover comprises an inner wall and can be rotatably opened or fastened relative to the rear cover. The paper pressing device further comprises a press fit component which is fixedly arranged on the inner wall of the front cover, and the press fit component comprises a pressing and holding piece and at least one roller, wherein the pressing and holding piece comprises a fixing end and an elastic supporting arm which is connected to one side of the fixing end and is elastically bent relative to the fixing end; the elastic supporting arm is provided with at least one set of fixing sheets, and each set of the fixing sheets are provided with a set of corresponding shaft holes; and the rollers penetrates in the shaft holes of the fixing sheets and can roll relative to the shaft holes. The rollers of the paper pressing device and paper have rolling friction, and a contact area between the rollers and the paper is small, thus the frictions of the rollers and the paper can be reduced so as to reduce paper jam phenomena.
