A musical keyboard instrument which not only allows a music stand to be erected in a desired position in the transverse direction on a panel section, but also ensures easiness of viewing a written musical score of a music book even when the music stand is erected in the vicinity of the left or right end of the panel section. A keyboard section includes a plurality of keys arranged in a front part thereof. A panel section is provided at a location rearward of the keyboard section. An arcuate groove part is formed in the panel section, for engagement with leg parts of a music stand. The arcuate groove part is formed such that the leg parts of the music stand can be engaged therewith in a desired position in the transverse direction, and is curved in a rearwardly convex manner.

An image forming device for preventing the lowering of the cleaning performance due to rolling up of the blade-like member, by reducing a force of rolling up both end parts of the blade-like member. The blade-like member is provided which presses the contact part extending in parallel in the axial direction of the support member against at least one support member with a belt-like member wound therearound and having the roller shape, with the belt-like member having an endless form interposed therebetween. Provision of tapered parts sloped with outer diameters reduced toward both end parts in the axial direction at both end parts in the axial direction of the one support member having a roller shape, makes the contact pressure of the contact parts at the blade-like member against the one support member having the roller shape, smaller at both end parts than at the central part in the axial direction of the support member.

A belt driving device in which an endless belt is spanned around a drive pulley and a driven pulley and the belt is driven by rotation of the drive pulley includes a belt shift correcting member for correcting shifting of the endless belt. When the endless belt is shifted towards one side in an axial direction of one of the drive pulley and the driven pulley, the belt shift correcting member increases an angle of a circumference of the one of the drive and driven pulleys contacting a width-wise end part of the endless belt at the one side such that the angle of the circumference of the one of the drive and driven pulleys contacting the width-wise end part of the endless belt at the one side is larger at a part of the one of the drive and driven pulleys contacting an edge part of the width-wise end part of the endless belt than at other parts of the one of the drive and driven pulleys contacting other parts of the width-wise end part of the endless belt, and the angle of the circumference of the one of the drive and driven pulleys contacting the width-wise end part of the endless belt decreases toward a part of the one of the drive and driven pulleys contacting a width-wise center part of the endless belt. Furthermore, a coefficient of friction relative to the endless belt is made higher at a circumferential surface of an axial end part of the one of the drive and driven pulleys, which comes in contact with the width-wise end part of the endless belt at the one side in the axial direction of the one of the drive and driven pulleys, than at a circumferential surface of an axial center part of the one of the drive and driven pulleys.

An overhead traveling carrier system carries a package along a rail supported by a roof, and stops a vehicle at a target position; when the vehicle of the overhead traveling carrier system enters an area around the target position, the overhead traveling carrier system stops the vehicle, and changes the relative position between the vehicle and a handling unit mounted on the vehicle during the downward motion of the handling unit toward the destination, thereby speedily aligning the package with the destination.

A thermal printer that prints on a recording sheet by holding the recording sheet between a thermal print head and a platen, driving the thermal print head to generate heat and driving the platen to feed the recording sheet comprises an approach limiting means that limits the approach of the thermal print head to the platen and determines a minimum distance between the thermal print head and the platen. The approach limiting means is provided with a stopping member for stopping the thermal print head or a print head holding member holding the thermal print head moving toward the platen to limit the approach of the thermal print head to the platen and to determine a minimum distance between the thermal print head and the platen. The thermal printer reduces the bias of distribution of the pressure of the thermal print head on the recording sheet along the width of the same and is capable of printing characters and the like clearly over the entire width of the recording sheet.

The foam-dispensing pump container according to the present invention has the valve seat portion which protrudes inwardly below the air-liquid mixing unit and which is formed of the flexible member that can come into contact with the outer peripheral face of the latch portion of the rod-shaped valve body, and immediately after the nozzle head starts rising, the flexible valve seat portion comes into contact with the rod-shaped valve body before the upper opening end of the liquid chamber comes into contact with the rod-shaped valve body, thereby significantly reducing a backflow of the foam or liquid into the air passage, and consequently improving the usability of the foam-dispensing pump container.

A case includes an assembling hole portion and a snap ring preassembled hereto. When fixing a bearing to the case, a first distance between both ends of the snap ring can be expanded within the assembling hole portion. The bearing is used for supporting a rotational shaft of the case. The assembling hole portion includes dual hole portions, which open at respective positions where the both ends of the snap ring can be expanded within the dual hole portions.

A planetary gear type transmission includes a planetary gear mechanism including a sun gear, a ring gear, and a planetary carrier which all have the same axis, an output shaft having the same axis as the planetary gear mechanism, a sleeve supported movable in an axial direction by the output shaft, an inner piece connected to the sleeve while the sleeve is approaching the planetary gear mechanism and including a first inner spline, and an outer piece connected to the sleeve while the sleeve is separating from the planetary gear mechanism and including a second outer spline. The sleeve includes a first outer spline fitted to the first inner spline and a second inner spline fitted to the second outer spline. A distance between the second inner spline and the planetary gear mechanism is smaller than a distance between the first outer spline and the planetary gear mechanism.
