Even if you remove the pressure from the switch and turn it off, the H state remains, while the other switch, for example? When the speed display switch 21 is pressed, the reset terminal T1 of the first memory circuit A1 goes into the H state via the second diode D2, so that the output of the first memory circuit A1 shifts to the low level state (L state). It has become.

34 is the power switch 19 and the display time regulation circuit F.
This is a normally closed type pulse rate sensor switch that short-circuits the input terminal S4 of the pulse rate sensor switch, and has an actuation button 34'' protruding inward from the pulse rate sensor mounting hole 26 of the housing 10, and the pulse rate sensor 17 connection terminal 17'AE. When inserted into the mounting hole 26, the circuit is opened, that is, the circuit is maintained in an open state when measuring the pulse rate.

To explain the operation of the display output selection section, the display case 1
Pulse sensor connection terminal 1 is inserted into the pulse rate sensor attachment hole 26 of 0.
7' is inserted and the power switch 19 is closed, the motion display switch, e.g., the time display switch 20
When is pressed, the first input terminal G11 of the first three-input AND circuit B1 goes into the H state via the fourth diode D4, and the output of the first memory circuit A1 also goes into the H state.

At this time, if the scan output of the microcomputer device 30 is output to the first scan output terminal R1, the output of the first 3-input AND gate circuit B1 becomes an H state and is input to the key input terminal K. Exercise information indicating usage time is output from the device 30 and displayed on the display element 18, and the time lamp 23 is turned on.

After that, even if the time display switch 20 is released, the display remains unchanged.

On the other hand, when the switch 20 is pressed, the input terminal s4 of the display time regulation circuit F temporarily becomes an H state, and the timer built in the display time regulation circuit F becomes a clear state and is reset.

Thereafter, when the time display switch 20 is opened, the timer is activated and starts measuring time, and after 7 seconds have elapsed, the output terminal P of the display time regulation circuit F changes from the H state output to the low state output.

At this time, the first input terminal G of the first 3-input AND circuit B,
ll is in the L state, and a pulse output in the H state is applied via the inverting circuit L to one input terminal G6 of the second AND gate circuit C2.

At this time, if the scan output of the microcomputer device 30 is output to the third scan output terminal R3, the second AN
D) Since the output of the circuit C2 becomes H state and is input to the key input terminal K, the microcomputer device 30
When the pulse rate information is output from the display element 18 and the pulse rate is displayed on the display element 18, the pulse rate display lamp 25 is lit.

If another 7 seconds pass, the display time regulation circuit F shifts to the H state output again, so the first 3-input AND gate circuit B
Since the first input terminal Gll of the circuit is in the H state and the input of the second AND gate circuit C2 is in the L state, the usage time is displayed in the same way as above, and thereafter the pulse rate information and the exercise information of the usage time are displayed every 7 seconds. This is repeatedly displayed on the display element 18, and the pulse rate display lamp 25 and time display lamp 23 are alternately turned on.

Furthermore, when the traveling speed display switch 21 is depressed, the traveling speed and pulse rate information are similarly repeated every 7 seconds, and the display element 18
At the same time, the speed display lamp 24 and the pulse rate display lamp 25 are alternately lit.

Furthermore, when the pulse rate display switch 22 is suppressed, the IAND
The two input terminals G4jG, of the gate circuit C1 are both in the H state, and therefore one input terminal G6 of the second AND gate circuit C2 is in the H state. If input to the other input terminal G, via
The H state output from the AND gate circuit C2 is the key input terminal K.
Since the pulse rate information is outputted from the microcomputer device 30, the display element 18 displays the pulse rate and at the same time lights up the pulse rate display lamp 25. After 7 seconds have elapsed, the pulse rate information is also outputted from the microcomputer device 30. This is repeated thereafter, so that only the pulse rate is displayed on the display element.

The first and second differentiating circuits J1 and J2 convert the output of the display time regulation circuit F into trigger pulses of about somsec, respectively, and are connected to the first three-input AND gate circuit B1 or the second three-input AND gate circuit B1. By inputting the output of the display time regulating circuit F as a trigger to the AND gate circuit B2 and the second AND gate circuit C2, exercise information and pulse rate information are alternately and reliably displayed on the display element 8. It is something.

Next, when the pulse rate sensor connection terminal 17' is removed from the pulse rate sensor mounting hole 26, the pulse rate sensor switch 34 is closed, and therefore, the input terminal S4 of the display time regulation circuit F remains in the H state, so the circuit F does not measure time. , output terminal P8 is H
The state output is maintained, so the second AND gate circuit C2 is L.
state, and the pulse rate is not displayed on the display element 1B.

Furthermore, FIG. 5 shows another embodiment of an indoor jogger, in which 35 is a running belt, 36 is a roller shaft, and the magnets 11 of the wheel rotation sensor 13 are on the side of this roller shaft 36. In the part, the Hall element 12 is connected to the chassis 37.
attached to the side.

Moreover, it has a plurality of pushbutton switches for selecting these pieces of information, and a display time regulation circuit for regulating the display time, and when the movement display switch among these pushbutton switches is pressed, the display is Movement information and pulse rate information are taken out alternately in accordance with the bistable state output of the time regulation circuit, and on the other hand, when the pulse rate display switch among these pushbutton switches is pressed, an inversion circuit is added to the display time regulation circuit. When connected, the bistable state output of the display time regulation circuit is converted to one stable state output and only the pulse rate information is taken out, so it can be used as a display for exercise information such as usage time and running speed. Even in the display state, pulse rate information can be known at predetermined intervals, so the user can always know the user's exercise status, and therefore can be careful not to overload the exercise status. Therefore, overexertion is prevented, and since exercise information and pulse rate information are repeatedly displayed on the display, it is possible to provide an exercise equipment that has a strong entertainment element and is fun to use.
