Abstract: A traveling robot includes: a traveling body including a truck and a drive unit, the truck including front and rear wheels and a floor frame, the drive unit being configured to rotate the wheels; a support mechanism configured to raise or lower a holding tool configured to support a mounting plate; and a picking robot configured to load a cargo onto the mounting plate or unload the cargo from the mounting plate. The drive unit is mounted on the floor frame, and the floor frame includes a projecting portion projecting forward from a portion on which the drive unit is mounted. The support mechanism is attached to a front end portion of the projecting portion. The picking robot is provided at the projecting portion, is arranged between the support mechanism and the drive unit in a front-rear direction, and is arranged on or behind an imaginary vertical line passing through a front axle.

Abstract: Provided is a pressurized pen, which is enabled to enhance the sealing property of a compression chamber at a pressurizing time in the knocking operation of a knock mechanism and to improve the durability. A pressuring pump mechanism includes: a pressure member having a front end opening portion communicating with the inside of a medium containing tube and a compression chamber made extensible and contractible in axial direction; and a push member for coming in axial direction into and out of abutment against a rear end opening portion of the pressure member and for pushing the compression chamber of the pressure member in a gas-tight condition in a compressing direction. The push member is associated with the pushing action of a knock mechanism such that it is enabled to irrotationally move toward the rear end opening portion of the pressure member.

Abstract: A pressurized pen having excellent feeling of using it by allowing an easy knocking operation with small force is disclosed. The pressurizing member 18 includes an elastic cylindrical member 19. The elastic cylindrical member 19 has a large-diameter front cylinder portion of which a front end 20a in air-tight manner communicates directly with the rear opening portion 6b of an ink containing tube 6 and which forms the pressurizing chamber 22, and a small-diameter rear cylinder portion 21 which is coaxially connected to a rear end of the front cylinder portion 20 and in which the front end portion 17a of the pressing member 17 is pressed into a rear aperture 21a thereof. The inside of the ink containing tube 6 is pressurized by allowing the pressing member 17 to press the rear cylinder portion 21 into the front cylinder portion 20 and compressing the elastic cylindrical member 19 in the axial direction with the pressing chamber 22 air-tight.
