This invention discloses a physical exercise appliance comprising an indicator device for selectively indicating exercise data or heart-pulse frequency data of the user or exerciser during the application of his physical energy. A circuit is provided for alternately indicating the exercise data and the heart-pulse frequency data on the indicator device at predetermined intervals when the indication of exercise data is designated. The circuit only indicates the heart-pulse frequency data on the indicator device when the indication of heart-pulse frequency data is designated. The heart-pulse frequency data may be read out at predetermined intervals, while exercise data such as an exercise period of time or an exercise speed are indicated on the indicator device. Therefore the user or exerciser can always know his physical conditions during the application of his physical energy and can pay attention such that he does not apply excessively his physical energy, thereby preventing him from becoming too tired. Furthermore, such repeated indication of exercise data and heart-pulse frequency data on the indicator device may also provide an entertaining atmosphere, so that the user may take exercise pleasantly.

1. Physical exercise appliance comprising: a single digital indicator device for selectively displaying exercise data or heart-pulse frequency data of the user during the application of his physical energy; a plurality of indication switches to cause the exercise data and the heart-pulse frequency data to be respectively indicated on said digital indicator device; an indication time control circuit for alternately producing two stable state outputs that control the display period of time for the exercise data and the heart-pulse frequency data displayed on said indicator device, respectively; means for automatically and alternately causing the exercise data and the heart-pulse frequency data to be displayed on said single digital indicator device for a period dependent on said two stable state outputs of said indication time control circuit when an exercise data indication switch, among said plurality of indication switches, is activated; and an inverter circuit for inverting one of said two stable state outputs of said indication display time control circuit when a heart-pulse frequency indication switch, among said plurality of indication switches, is activated so that only the heart-pulse frequency data is read out. 2. Physical exercise appliance comprising: a rotary load member; a heart-pulse sensor for detecting the heart-pulse frequency of the user during the application of his physical energy to rotation of the rotary load member, said heart-pulse sensor generating a pulse frequency output signal related to the detected heart-pulse frequency; a rotation sensor for detecting the number of rotations of the rotary load member and generating a rotation signal related to the number of rotations; computing means for computing heart-pulse frequency data and exercise data, including exercise speed, in response to the pulse frequency output signal and rotation signal; a single digital indicator device for selectively displaying said heart-pulse frequency data or said exercise data computed by said computing means; a plurality of display lamps for indicating which data, either heart-pulse frequency data or exercise data, is being displayed on said digital indicator device; a plurality of display switches for designating the data to be displayed on said digital indicator device; means for automatically and alternately causing said exercise data and said heart-pulse frequency data to be displayed on said digital indicator device at predetermined intervals and for turning on the display lamp corresponding to the data currently displayed on said digital indicator device; said heart-pulse sensor having a connecting plug which is removably mounted to a heart-pulse sensor mounting hole of an indicator case in which the digital indicator device is disposed; a plug switch located on said indicator case, which plug switch is opened and closed dependent on the attachment and removal of said connecting plug to and from said heart-pulse sensor mounting hole, and means responsive to said plug switch for permitting only the exercise data to be indicated on said digital indicator device when the connecting plug is removed. 3. The physical exercise appliance as set forth in claim 3, wherein the exercise data includes an exercise period of time and an exercise speed.
