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.

Provided is a bill handling device which comprises: a bill deposit / withdrawal opening (10) where bills to be deposited / withdrawn are collected; a bill discrimination unit (40) for distinguishing bills; a temporary storage part (20) for temporarily collecting and storing bills; bill storage units (30 - 33) for storing and re-separating bills; and bill conveyance paths (50 - 61) for conveying bills to the bill storage units (30 - 33), wherein the bill conveyance paths are each driven by an independent motor, and the bill conveyance speed of the bill conveyance paths is subject to stepwise acceleration control.

An image forming device and its paper discharge mechanism, the paper discharge mechanism includes: a tray for carrying paper discharged from a paper outlet along a discharge direction, the tray is located at an initial inclined position in a paper discharge state, and in a post-processing state The tray is located at a horizontal position; an adjustment part, linked with the tray, is used to adjust the tray to the horizontal position and the initial inclined position; the storage part is arranged at the upstream end of the tray along the discharge direction; a holding part, in the post-processing state, the holding part protrudes from the receiving part to the carrying surface of the tray, so that the upstream end of the paper on the tray along the discharge direction abuts against the holding part; In the paper discharge state, the holding part is located in the storage part; the interlocking part makes the holding part be located in the storage part before the tray is adjusted to the initial inclined position by the adjustment part. The invention solves the problem that the paper discharge mechanism of the existing image forming device cannot solve paper jams and low productivity at the same time.

The invention discloses a paper feeding sensor of a miniprinter. The sensor comprises an installation frame connected to a printer engine, a touch arm, and a support provided with a photoelectric sensor, wherein a rotary shaft perpendicular to the touch arm is arranged at one end of the touch arm, the touch arm is hinged to one end of the installation frame through the rotary shaft, the rotary shaft is sleeved with a torsion spring, one of the two positioning ends of the torsion spring is clamped to the touch arm, and the other positioning end of the torsion spring is clamped to the installation frame; the support is installed on the installation frame and provided with a light sensing channel, a limiting block is arranged on the lower side of the touch arm, a limiting surface is arranged at the lower end of the installation frame, the limiting block is matched with the limiting surface to enable the lower side face of the touch arm to be as high as the upper edge of the light sensing channel, and a sensing part protruding out of the installation frame is arranged on the upper side face of the touch arm. The photoelectric sensor is combined with a mechanical blocking structure, reaction speed is high, required printing paper pressure is small, paper feeding is smoother, paper jamming is reduced, and the paper feeding sensor is suitable for printing paper in dark color.

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 discloses a data processor comprising a printer, the printer comprises a support, a motor and a printer gear, wherein an output shaft of the motor penetrates through the support, and an outer shell of the motor is fixed on the support. The printer gear is connected with the output shaft of the motor, and a protective cover is further arranged on the support and surrounds the printer gear. The invention further provides a gas chromatograph provided with the data processor. Due to the fact that the protective cover is arranged on the support and surrounds the printer gear, paper scraps brought down in a paper feeding process can be effectively prevented from falling on the printer gear, and the occurrence rate of the paper-jam phenomenon can be reduced, so that the fault rate of the gas chromatograph is reduced, and maintenance cost is reduced.

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.
