Abstract: A pulsimeter comprises a pulse sensor portion including a light emitting diode and a photodiade, and a main body, the pulse sensor portion and the main body being connected through a cord. The main body includes a received light comparing circuit for comparing a quantity of light received by the photodiode with a predetermined valve, and a display device for displaying a result of the comparison. If there is no abnormality in the cord and the pulse sensor portion in normal condition is not in contact with a human body, the quantity of received light in increased to cause a light emitting diode of the display device to be turned on. On the other hand, if there is any abnormality in the cord or the pulse sensor portion, the quantity of received light is not increased and the light emitting diode is not turned on. While the pulsimeter in normal condition is being used, the light emitting diode is not turned on because of light transmission through the human body.

Abstract: A roller 26 for applying a load to a tire 44 of a rear wheel as a drive wheel is rotatably supported by support frames 30 through a roller shaft 24. The support frames 30 are rotatable about a fixing shaft 28 penetrating their ends. A support portion 29 supporting the fixing shaft 28 is fixed to a load applying device stand 2 to be inserted in a rear frame 22. A coil spring 34 is provided between a fixing plate 32 fixed to the load applying device stand 2 and a transverse plate 31 of the support frames 30. A pedal clamp 38 to be engaged with the plate 31 in a state of the coil spring 34 being compressed is rotatably provided on the load applying device stand 2. When a load applying device is to be used, the position of the load applying device stand 2 is adjusted so that the roller 26 slightly contacts the rear wheel tire 44 with the pedal clamp 38 being engaged with the plate 31.

Abstract: A running data display unit (1) for a bicycle calculates running data such as running speed, running distance, average speed, maximum speed etc. of a bicycle, based on pulse signals from a revolution detecting portion (3). This calculation is performed by a microcomputer incorporated in the display unit. The running data obtained by the calculation are displayed in a digital form on a liquid crystal display panel (15). The panel (15) gives display of a speed unit km/h or mile/h selectively. This display of km/h (or mile/h) emits a winking light when the microcomputer measures determined running data such as the running distance, the average speed etc. and emits uninterrupted light when measuring of such running data is stopped. As a result, the rider of the bicycle can immediately ascertain whether measuring operation is being made or not.

Abstract: A running data display unit (1) for a bicycle calculates running data such as running speed, running distance, average speed, maximum speed etc. of a bicycle, based on pulse signals from a revolution detecting portion (3). This calculation is performed by a microcomputer incorporated in the display unit. The running data obtained by the calculation are displayed in a digital form on a liquid crystal display panel (15). The liquid crystal panel (15) also makes display of a pulse mark (26). The display of the pulse mark (26) turns on and off alternately at the rise of the pulse applied normally from the revolution detecting portion (3). As a result, by the display of the pulse mark (26), the rider of the bicycle can ascertain normal operation of the display unit (1), particularly normal operation of the revolution detecting portion (3).

Abstract: A running data display unit (1) for a bicycle calculates running data such as running speed, running distance, average speed, maximum speed etc. of a bicycle, based on pulse signals from a revolution detecting portion (3). This calculation is performed by a microcomputer incorporated in the display unit. The running data obtained by the calculation are displayed in a digital form on a liquid crystal display panel (15). If the running data displayed on the panel (15) is the running distance, the running distance is represented as a numerical value including five figures at maximum. The running distance not attaining 1000 km (or miles) is represented down to two decimal places and when the running distance attains 1000 km (or miles), the manners of display is automatically by the microcomputer (30) changed so that display is made down to only the decimal place.

Abstract: A lighting fixture including a body, an elastic member integrally attached to said body through a washer, the elastic member being engaged with a handlebar portion of, e.g. a bicycle, and a belt attached to one end of said washer. The belt is wound around the handlebar portion with the free end being fixedly inserted into a space defined at the other end of said washer, whereby the body is fixedly attached to said bicycle. The washer is detachably attached to the body by complementary engagement means provided on the bottom of said body and on the side of the washer facing the bottom so as to allow said washer to be selectively located in a plurality of directions with respect to said body. The complementary engagement means comprise projections or engagements on the body or the washer, respectively which engage within holes or recesses in the washer or the body, respectively.

Abstract: An illuminating device for a wheeled vehicle, such as a bicycle, comprising a light housing and a battery case pivotally secured to one another by means including a pair of branched arm portions so that vertical angle of the position of said light housing can be adjusted. Metallic terminals for positive and negative current are provided in a battery case to press and hold batteries therein and the respective ends thereof extend from the battery case along the inner sides of the arm portions. Metallic terminals for positive and negative current in the light housing extend to a base portion of the light housing in through holes in the base portion.
