Or twist and do strength training. As a means for generating the force detection signal, instead of the combination of the conductive piece and the contact detection signal generation circuit shown in FIG. 2, a micro switch is driven by mechanical deformation to detect the closing of the switch. Thus, a circuit configuration for generating a force detection signal may be adopted.

  FIG. 3 shows that the exercise tool body of the force exercise tool 1 is provided with a predetermined length so that the string-like body 41 that is elastic and can be extended in the length direction by the force is indicated by a two-dot chain line 41a. In contrast, a grip portion 42 is attached to both ends of the string-like body 41 of the exercise tool body, and a force applied to the string-like body 41 is applied in the vicinity of the grip portion 42 to the wire fixing plug. 43, a switch 46 for detecting via a wire 44 and a spring 45 is provided, and a switch operation detection signal generating circuit (not shown) for electrically detecting the operation of the switch 46 and generating a switch operation detection signal is provided.

In the embodiment shown in FIG. 3, the switch 46 is provided in each of the left and right grips 42 to detect the applied force of each of the left and right hands. However, the switch 46 is provided in either one of the grips 42. Thus, it may be configured to detect only the applied force of one hand.

  Next, the data processing process of the training tool of the present invention will be described with reference to FIGS. 4a and 4b. The flow of FIG. 4a is a main routine, and the flow of FIG. 4b is an interrupt routine. When the apparatus is turned on, the training tool is initially set in step S1. Next, in step S2, the setting by the panel switch is read, and the operation mode of the training tool using the present invention is set. In the above description, as the operation mode of the present invention, the performance mode in which the tempo of the music progression is made to follow the input time interval of the force detection signal in the automatic performance based on the automatic performance data has been described. As a training tool to be used, another performance mode other than this mode (for example, a mode for playing a musical tone of the next pitch for each new force detection signal in response to the force detection signal) is also prepared. Since the diversity of muscle strength training is convenient and convenient, this flowchart illustrates a process that can cope with such another performance mode. In this case, the performance mode of the present invention described above is referred to as “mode 1”, and another performance mode is referred to as “mode 2”. Note that the circuit configuration for mode 2 can be separately provided, and a specific description thereof will be omitted here.

  Next, the performance data of the music to be performed described above is stored in the performance data storage means for a plurality of music, and numbered in advance, and can be selected by inputting from the panel switch. Step S3 is the music selection step. When the performance start button is pressed, step S4 is determined to be YES (Y), and the process proceeds to step S5 below. If the selection by the panel switch is determined to be “mode 1”, the training tool of the present invention is The operation described above is performed. That is, the tempo of the automatic performance of the music is corrected from moment to moment following the rising time interval of each force detection signal from the force exerciser. In this case, the process for detecting the rise of the force detection signal is performed as follows. In other words, the reception of the force detection signal is periodically checked (for example, every 1 millisecond), and the first “with force detection signal” after detecting “no force detection signal” is the new force detection signal. Means the rising point of The rise of the force detection signal does not exist while only “with a force detection signal” continues or while only “without a force signal” continues. Through this process, the user who is doing strength training realizes the beat of the rhythm of the song at every moment when the force is applied, so that he can feel as if he is conducting music performance. Can do strength training.

  Here, an interrupt routine that is not described above will be described. The interrupt routine is a process executed every time an interrupt occurs. Step S11 prompts the execution of processing in the corresponding main routine when there is an input in any of the switches. If the input is related to mode setting, the corresponding processing is executed in the subroutine of step S2. If the input is related to music selection, the corresponding processing is executed in the subroutine of step S3. If it is an input of a start button, it will progress to "Y" by judgment of step S4. While there is no input of the start button, the process proceeds to “N” in the determination of step S4 and continues to wait for the input of the start button. Step S12 is used for data processing in the subroutine of step S6 or S7 as an input of the force detection signal when there is a wireless input. Step S13 is a step of creating a force interval signal used for tracking the tempo of automatic performance in step S6 described above.

However, a plurality of force exercisers assigned different radio transmission frequencies or individually connected by wire are connected. A plurality of users can perform muscle strength training by using a plurality of force exercising tools. In that case, the musical tone performance apparatus 2 has a signal processing circuit configuration of a plurality of channels, performance data is also stored in a plurality of instrument parts, and a plurality of users share a plurality of instrument parts. When training, the performance tempo is determined at the timing of the reader's force with a specific person as the leader. For other users, only those who are training at the same timing as the leader's training If the sound of the musical instrument part shared by the person is made to sound, the performance will proceed smoothly and will be in good condition.
