Abstract: A force-sensitive key module and a force-sensitive switch structure are provided. The force-sensitive switch structure includes a first protective layer, a second protective layer, a first conductive layer, a second conductive layer and a force-sensitive layer. The first protective layer receives a pressing force. The second conductive layer is aligned with the first conductive layer. The force-sensitive layer is installed on the first conductive layer or the second conductive layer. When the first protective layer receives the pressing force, an electric connection between the first conductive layer and the second conductive layer is established, and the force-sensitive layer generates an analog sensing signal in response to the pressing force. When a magnitude of the pressing force is changed, the analog sensing signal is correspondingly changed according to an impedance change of the force-sensitive layer.

Abstract: A ghost key preventing circuit includes plural driving lines, plural sensing lines, plural key switches, plural bias resistors and a controller. The plural driving lines and the plural sensing lines are collaboratively formed as a matrix circuit. The plural key switches are included in the matrix circuit. The plural bias resistors are connected with the corresponding sensing lines. When the key switch of a specified switch circuit is turned on, a divided voltage is generated and outputted from the specified switch circuit. The controller judges whether the key switch of the specified switch circuit is normally turned on or the key switch is a ghost key according to the divided voltage.

Abstract: A printing device includes a casing, an upper cover, plural light sources, and a sensing module. The plural light sources are used for emitting plural light beams. The upper cover is connected with the casing, and rotatable relative the casing. The plural light sources are disposed on the upper cover, and arranged in a row. The sensing module is disposed under the plural light sources, and movable relative to the casing along a specified direction. After the light beams transmitted through a gap of the transfer paper are received by the sensing module, the gap is detected by the sensing module. The plural light beams emitted by the plural light sources can be projected onto any movable position of the sensing module. In other words, it is not necessary to align the sensing module and the plural light beams.

Abstract: A composite function keyboard circuit includes a first matrix circuit, a first bias resistor group, a second matrix circuit, a second bias resistor group and a controller. Each switch unit in the first matrix circuit is an ink-type force sensing switch. A resistance of the ink-type force sensing switch is variable according to a pressing mode of a keypress action. An electrical connection path is formed between the ink-type force sensing switch and the corresponding bias resistor of the second bias resistor group. When the ink-type force sensing switch is electrically conducted, a divided sensing voltage is generated by the electrical connection path, and the controller generates a corresponding key control instruction according to a level of the divided sensing voltage. Furthermore, the cooperation of the first matrix circuit and the first bias resistor group can achieve a ghost key preventing function.

Abstract: A printing device with a marking function is provided. The printing device includes a printing module, an identification module and a marking member. The printing module is used for printing images on a transfer paper, thereby producing a barcode paper. The identification module is used for scanning the barcode paper, and judging the printing quality of the barcode paper. If the printing quality of the barcode paper is unqualified, the marking member produces a mark on the barcode paper. In addition, the barcode paper is successively transported through the printing module, the identification module and the marking member.
