Abstract: This wireless communication device is equipped with: an acquisition unit for acquiring, from an onboard network of a work vehicle, an in-vehicle signal that travels through the onboard network; and a control unit for controlling wireless communication between the work vehicle and a portable terminal, and transmitting the acquired in-vehicle signal to the portable terminal. As a result, it is possible to provide a wireless communication device with which a worker can verify the status of the work vehicle from outside the work vehicle.

Abstract: There is provided a working machine that includes an operated function unit, an in-vehicle network to be connected to an operation terminal via an external network, an operation unit that transmits an intrinsic operation signal related to operation of the operated function unit to the in-vehicle network, and a control unit that is connected to the operation unit via the in-vehicle network and controls the operated function unit on the basis of either a false operation signal generated by the operation terminal or the intrinsic operation signal.

Abstract: Provided is a work-machine erroneous forward/backward travelling operation notifying device capable of improving safety by notifying, when a travel direction inputted to an operation input unit does not conform to the condition of a transmission clutch, an operator of the non-conformance. Whether the conditions of clutches 121 to 124 conform to a travel direction inputted to a selection lever 141 is determined on the basis of a pressure Pf sensed by a first pressure sensor 133a or a pressure Pr sensed by a second pressure sensor 134a and the travelling direction inputted to the selection lever 141. When it is determined that the conditions of the clutches 121 to 124 do not conform to the travel direction inputted to the selection lever 141, a vehicle 10 is notified that an erroneous operation will occur.

Abstract: A thermal printer includes a main body frame, a thermal head swingably attached to the main body frame, a platen roller disposed to face a printing surface of the thermal head, and a motor for rotationally driving the platen roller. The thermal printer activates the thermal head while conveying a heat-sensitive paper held between the thermal head and the platen roller to perform printing on the heat-sensitive paper. The feeding amount of the heat-sensitive paper may be set so that an aspect ratio of the characters printed on the heat-sensitive paper is within a range of 0.95:1 to 0.8:1.

Abstract: Provided is a thermal printer in which when heat-sensitive paper is provided to the user, characters printed on the heat-sensitive paper may be received by a user without any uncomfortable feelings, and a use amount of the heat-sensitive paper may be reduced. A thermal printer (P1) includes: a main body frame (101); a thermal head (H) attached to the main body frame (101) to swing; a platen roller (102) disposed to face a printing surface of the thermal head (H); and a motor (M) for driving the platen roller (102), the thermal printer being configured to activate the thermal head (H) while conveying heat-sensitive paper held between the thermal head (H) and the platen roller (102) to perform printing on the heat-sensitive paper, in which a feeding amount of the heat-sensitive paper may be set so that an aspect ratio of the characters printed on the heat-sensitive paper is within a range of 0.95:1 to 0.8:1.

Abstract: A stepping motor driving circuit comprising control means for controlling rotation of a stepping motor, driving means for supplying the stepping motor with a driving signal consisting of excitation pulses in accordance with rotation control, chopping means for executing intermittent chopping of the excitation pulse, and voltage monitoring means for monitoring fluctuation of driving voltage, wherein the control means has means for adjusting the intermittent chopping execution time by controlling the chopping means in accordance with the monitored driving voltage. The driving circuit can be applied to rotation control of the stepping motor mounted on a line printer as a paper feed driving source. In this case, the control means controls rotation of the stepping motor synchronously with the line printing speed of the line printer.
