Grooves 33 are formed in the outer surface (not shown) of the rotor 30. The rope 331 may be received in the groove 33 and manually wound around the rotor 30. By pulling the rope 331 quickly to release it out of the groove 33 while the spherical casing is stopped, the rotor 30 causes the shaft 31 to lift the shaft 31 due to the friction between the rope 331 and the groove 33. It will rotate around the center. The rope 331 is described here merely as one exemplary method for rotating the rotor 30. Other means can be used to rotate the rotor 30 in the spherical casing. When the wrist exerciser 100 is operated using the rope 331, the user grips the wrist exerciser 100 with one hand and When the rope 331 is quickly pulled and released from the rotor 30 by the other hand, the rotor 30 rotates inside the casing. After the user rotates the rotor 30, the user can adjust and increase the rotational speed of the rotor 30 by rotating his hand, especially the wrist. Accordingly, it is possible to achieve the purpose of wrist exercise and the purpose of entertainment.

A number of light emitting elements 40, such as light emitting diodes (LEDs), are mounted on the outer surface of the rotor 30.

Includes a magnet ring 51. Two coils 52 of conductive wire are attached to and rotate with the rotor 30. The coil 52 is disposed to intersect the magnetic force line of the magnet ring 51 when the rotor 30 is rotating to induce a current in the coil 52. The adjusting circuit 53 is connected to the coil 52 to supply a direct current to the light emitting element 40 to provide a power supply Vcc (FIG. 3) to the light emitting element 40.

The control circuit 60 is fixed to the rotor 30. Preferably, the control circuit 60 is housed in a cavity (not shown) formed in the rotor 30. The control circuit 60 is connected to the light emitting device 40 to control the light on / off state of the light emitting device 40. The control circuit 60 can be any circuit as long as it can control the light emitting element 40.

It includes a unit. The microprocessor 61 has an input terminal 611 connected to the power supply Vcc or the control circuit 53 and a number of output terminals 612 connected to the light emitting element 40, respectively. In the illustrated embodiment, the light emitting element 40 is a light emitting diode each having two corresponding terminals respectively connected to a corresponding output terminal 612 and a power source Vcc of the microprocessor 61, thereby output terminal 612. When a low output is provided to a particular one of the light emitting diodes, the corresponding light emitting diode 40 is turned on. When high output is provided to the output terminal 612, the light emitting diode 40 is turned off.

By properly programming the microprocessor 60, the light emitting element 40 can be lit to indicate or display a particular shape or message.

The switch 62 is connected between the input terminal 611 of the microprocessor 61 and the power supply Vcc. The switch 62 allows the user to selectively operate the control circuit 60. The switch 62 may also function to allow a user to sequentially change between a number of operating modes preprogrammed in the microprocessor 61. Optionally, the switch 62 can be removed and the operating mode automatically changed during the rotation of the rotor 30.

In other words, in the illustrated embodiment, signal A is generated each time rotor 30 is fully rotated. Of course, it is also possible to mount more sensors on the wrist exerciser 100.

The signal A can be used to control the operation of the control circuit 60, for example, to determine when to turn on the light emitting element 40. For example, on the basis of the signal A applied to the microprocessor 61, the light emitting element 40 is provided with an opening 11 of the upper cover member 10 in order to make it easy to observe the message displayed to the viewer. Only when passing through the control circuit 60 can the light emitting element be turned on. The light emitting element 40 is turned off after leaving the opening 11. As a result, the total power consumption of the wrist exerciser 100 may be reduced.

The signal A is generated so that the microprocessor 61 can calculate the rotational speed of the rotor 30. The rotational speed can then be displayed by the light emitting element 40. Therefore, the counter and display device 70 described in the second embodiment can be omitted.

The sensor means 80 may be any suitable sensing device such as a reed switch and a photo switch. A device comprising a magnet and an induction coil can also be used as the sensor means 80 for generating a signal A.

Optionally, the frequency of electricity generated by generator 50 can also be used to calculate the rotational speed of rotor 30. This calculation can be easily performed by a properly programmed microprocessor 61.
