Abstract: A printer and its blade withdrawal mechanism, comprising: a fixing board, used for fixing a down cutter, the lower end of the fixing board can be pivotally installed on an installing support; a balance unit; a locking unit; and a manipulation unit, which is installed on the installing support, located at one side of the combination of the fixing board and the down-cut blade, and can move downward by two segment travels under the effect of external force, at the first segment travel, it can act on the balance unit, while at the second segment travel, it can act on the locking unit. The invention can simplify the handling of the faults such as paper jam, and improve the handling efficiency.

Abstract: A printer and its blade withdrawal mechanism, comprising: a fixing board, used for fixing a down cutter, the lower end of the fixing board can be pivotally installed on an installing support, and lower end of the installing support can be pivotally installed on a main body; a balance unit, which is installed on the installing support, and can act on the combination of the fixing board and the down-cut blade from front and rear, so as to enable the combination to be at non-pivotal state or at blade withdrawal state of pivoting by certain angle backward; a locking unit, for enabling the installing support to be at the locking state of being connected to the main body non-pivotally or at the open state of pivoting by certain angle forward; and a manipulation unit, which is installed on the installing support, located at one side of the combination of the fixing board and the down-cut blade, and can move downward by two segment travels under the effect of external force, at the first segment travel, it can act on

Abstract: A method for protecting Register Transfer Level (RTL) Intellectual Property (IP) core is provided, which converts an original RTL IP core to a target RTL IP core embedded with protection measures. The method includes: Step S1, constructing a state machine whose mode is controllable against the original RTL IP core, the state machine has a normal mode appeared corresponding to the normal function of the IP core after the entry of a correct preset secret key value and a fuzzy mode appeared corresponding to the abnormal function of the IP core after the entry of wrong secret key value; Step S2, revise the data flow of the RTL code in the original RTL IP core to obtain the fuzzy RTL code of the IP core; and Step S3: combine the state machine and the fuzzy RTL code into the targeted RTL IP core. By combining the secret key control and fuzzy data flow, the being embezzled and reverse-engineered of RTL IP core can be effectively prevented.

Abstract: An anti-counterfeit banknote recorder, an automatic teller machine and a system are provided. The recorder includes a microprocessor, a memory, a communication module and a first photographic device. The first photographic device includes a camera and a flasher with different types of rays. The microprocessor is able to regulate the flashlight automatically so as to provide different types of rays according to the optical characteristics on the surface of the banknote under monitoring, and control the camera so as to take photos of the banknote under monitoring, thus, photo information of the banknote is obtained. The microprocessor is able to receive commands from the external equipments via the communication module, thus, the first photographic device is controlled accordingly so as to take photos. Moreover, via the communication module, the microprocessor is able to receive transaction information in relation to the banknotes under monitoring from the external equipments.
