2. Description of the Related Art Conventionally, a device called a cycle computer has been known. This cycle computer is composed of keys for inputting the circumference and target speed of the bicycle wheel, and a rotation detection device for detecting the rotation of the wheel, etc. The target speed is set and displayed. Further, the rotation detection device, a magnet mounted on the spokes of the front wheels, a magnetic detection unit fixed to the vehicle body side and located outside the rotation track of the magnet,
A transmitter for wirelessly transmitting a magnetism detection signal from the magnetism detector,
And a receiver or the like that receives a signal from this transmitter.

Then, as the bicycle rotates, the front wheels rotate, and when the magnets attached to the spokes pass through the inside of the magnetism detecting portion, the magnetism detecting portion detects the magnetism and the transmitter detects the magnetism. The pulse signal is wirelessly transmitted in synchronization with. Then, the receiver receives the pulse signal, detects the start of the bicycle, counts the passage of the magnet thereafter, calculates the integrated distance by the "total count number x circumference", and "3600 / count cycle x The speed (hour speed) is calculated from the "circumference", and the calculated integrated distance and speed are displayed on the display unit provided on the receiver side. Therefore, by comparing the calculated target speed with the previously displayed target speed, it is possible to know whether or not the speed has reached the target speed.

[0004]

However, in the conventional cycle computer, the target speed is set by inputting an arbitrary value by key operation.
Therefore, when the target speed is set to be low, even if the target speed is achieved, it is not possible to sufficiently expect improvement in physical strength due to the training effect of traveling by bicycle. Also,
On the contrary, when the target speed is set to be high, excessive exercise amount equal to or higher than the training level of the user is required and fatigue accumulates, so that it is difficult to drive the bicycle at the optimal exercise amount. It was

The present invention has been made in view of such conventional problems, and an object thereof is to provide an optimum exercise amount setting device useful for running a bicycle at an optimum exercise amount.

[0006]

In order to solve the above problems, according to the present invention, there is a relationship between a pulse measuring means for measuring the pulse rate of a person who runs a bicycle and the amount of exercise of the person who runs the bicycle. In the pulse range calculation means for calculating the optimum pulse range, the comparison means for comparing the pulse rate measured by the pulse rate measurement means and the optimum pulse range calculated by the pulse range calculation means, and the comparison of the comparison means Display means for displaying the result. Further, in another configuration of the present invention, based on the comparison result of the comparison means, so that the pulse rate is within the pulse range, has a gear drive means for switching the gear of the bicycle, Alternatively, it has both the display means and the gear drive means.

[0007]

In the above structure, the pulse range calculating means calculates the optimum pulse range in relation to the exercise amount of the person who runs the bicycle, while the pulse rate measuring means detects the pulse rate of the person who runs the bicycle. With this detected pulse rate,
The optimum pulse range is compared with the comparison means, and the result is displayed on the display means. Therefore, by visually recognizing the content displayed on the display means, it is possible to determine whether or not the amount of exercise that the bicycle is currently traveling is appropriate. Further, the gear driving means switches the gear of the bicycle so that the pulse rate is within the pulse range, so that the bicycle can travel with a gear that matches an appropriate amount of exercise.
