 Embodiments will be described below with reference to the drawings. Reference numeral 1 is a bench main body which is lowered frontward, and a foot support plate 3 is fixedly provided on the upper surface of an upper surface plate 2 thereof or is erected so as to be adjustable in tilt angle. Below the upper surface plate 2, a support rod 5 for supporting the rack 4 is attached. The rack 4 and the support rod 5 are parallel to the top plate 2 in the front-rear direction, and the bearings 6 and 7 fixed to the respective ends of the rack 4 are slidably fitted to the support rod 5 so that the rack 4 moves forward and backward. Can move in any direction. Further, the top plate 2 is penetrated by an elongated hole 8 having a narrow width center, and a rod 9 standing upright on a front bearing 6 penetrates the elongated hole 8 upward, and a gripping bar is horizontally horizontally attached to the top of the rod 9. 10 is fixed. The pinion 11 that meshes with the rack 4 is driven by a motor 12 that rotates in forward and reverse directions. A light emitting device 13 and a light receiving device 14 of the optical sensor are provided on both sides of the rack 4 so as to face each other, and the rack, that is, the grip bar 9 advances (or retreats) by 2 mm each time one tooth of the rack 4 is detected. Equivalent to what you do.

Next, a block circuit diagram will be described. A controller 15 is composed of a first input port 16, a second input port 17, a control unit 18, a first output port 19, a second output port 20, a third output port 21, a memory 22 and an arithmetic unit 23. Has been done. The first input port 16 supplies the on / off state of the intensity selection switch S1, the start switch S2, the hand switch S3 and the return switch S4 to the control unit 18, and the second input port 17 detects the detection of the optical sensor 24. The pulse is supplied to the control unit 18, and various operations according to the state are performed using the memory 22 and the arithmetic unit 23 through the display unit 25, the motor drive system 26, and the buzzer 27.

The operation will be described with reference to the flowchart based on the block circuit diagram. The operation mode is selected by the intensity selection switch S1 (step P1). That is, when it is "1", the motor rotates at low speed, and when it is "2", it rotates at high speed. When "OFF" is selected, the process goes directly to the end step and all the operating switches are invalidated (step P2).

The start-up switch S2 is inserted (step P3). A reverse rotation signal is supplied from the control unit 18 to the motor drive system 12 via the second output port 20, and the motor reversely rotates based on the reverse rotation signal. This reverse rotation is performed until the grip bar 10 returns to the last retracted position (step P4). At the same time, the data related to the counter in the memory 22 is initialized at the same time (step P5).

The hand switch S3 is turned on (step P6). One drive pulse having a short pulse width is supplied to the buzzer 27 via the control unit 18 and the third output port 21 to make a beeping sound (step P7).

After that, a normal rotation signal is supplied from the control unit 18 to the motor drive system 26 via the second output port 20, the motor rotates in the normal direction, and the grip bar 10 advances (step P8). At this time, the optical sensor detects the teeth of the rack 4 and gives a detection pulse to the controller 18. The control unit 18 reads the number of pulses, registers it in the pitch number counter 28 in the memory 22, and updates it (step P9). The operations of steps P8 and P9 are performed until the hand switch S3 is turned on (step P10). Then, when the trainer holding the grip bar 10 further advances by moving the grip bar 10 forward, an interrupt is generated when the switch S3 at the hand side is turned on when it is thought to be tight, and steps P8 to P10 are performed. The operation loop is released, and a stop signal is given from the controller 18 to the motor drive system 26 to stop the motor (step P11). At this time, the number of pitches (2 mm per pulse) corresponding to the distance traveled by the grip bar 10 is registered in the pitch number counter 28 of the memory 22.

Next, a reverse rotation signal is applied to the motor drive system 26 to return the grip bar 10 to the original position (last retracted position) (step P12).

Next, a normal rotation signal is given to the motor drive system 26 to move the grip bar 10 forward (step P13). Simultaneously with the forward movement of the grip bar 10, the number of pulses detected by the optical sensor is registered and updated in the work counter 29 of the memory 22 (step P14). The operations of steps P13 and P14 are performed until the number of pulses in the work counter 29 becomes the same as the number of pulses in the pitch number counter 28 (step P15). When they are the same, a reverse rotation signal is given to the motor drive system 26 to return the grip bar to its original position (step P16), and the work counter 29 is initialized (step P17). The individual items are updated (step P18). Then, in the next step P19, it is judged whether the number counter 30 reaches "3" or the hand switch S3 is turned on. If neither is satisfied, the process returns to step P13, and the steps up to step P19. Repeat the operation. When the number counter 30 is "3" or when the trainee wants to skip the above operation three times during the operation, when the hand switch S3 is turned on and the hand switch on interrupt occurs, In step P20, the number counter 30 is initialized.

Next, a normal rotation signal is given to the motor drive system 26 to move the grip bar 10 forward (step P21). At this time, the number of pulses detected by the optical sensor 24 is registered and updated in the work counter 29 (step P22). The operations of steps P21 and P22 are performed until the number of pulses in the work counter 29 becomes equal to the number of pulses in the pitch number counter 28 (step P23). When they are the same, a reverse rotation signal is given to the motor drive system 26 to return the grip bar 10 to its original position (step P24), the work counter 29 is initialized (step P25), and the number counter 30 is updated by one. Put (step P26). Then, in the next step 27, it is judged whether the number counter 30 has reached 15 or whether the hand switch S3 is turned on. If neither is satisfied, the pitch number counter 28 is updated by 2 cm, that is, 10 pulses. The process returns to step P21 together with step P28), and the operations up to step P27 are repeated. When the number counter 30 is 15 or when the trainee wants to skip the above 15 operations in the middle of the process and an interrupt occurs due to turning on the hand switch S3, the process proceeds to the next step P29. The frequency counter 30 is initialized with.

Next, a normal rotation signal is given to the motor drive system 26 to move the grip bar 10 forward (step P30). Simultaneously with the forward movement, the number of pulses detected by the optical sensor is registered and updated in the work counter 29 (step P31). The operations of steps P30 and P31 are performed until the number of pulses in the work counter 29 becomes the same as the number of pulses in the pitch number counter 28 (step 32). When they are the same, a reverse signal is given to the motor drive system 26 to return the grip bar 10 to its original position (step 33), and the work counter 29 is initialized (step P34). Individually update (Step P35). Then, at the next step P36, it is judged whether the number counter 30 reaches "10" or the hand switch S3 is turned on. If neither is satisfied, the process returns to step P30 and the operation up to step P36 is performed. repeat. Then, when the hand counter S3 is turned on when the number counter 30 is "10" or when the trainee wants to omit the above 10 times of operation, when the hand switch on interrupt occurs, the next step P37 is performed. Then, the number counter 30 is initialized.

Next, a normal rotation signal is given to the motor drive system 26 to move the grip bar 10 forward (step P38), and at the same time, the number of detection pulses from the optical sensor 24 is registered and updated in the work counter 29 (step P38). P39). The operations of steps P38 and P39 are performed until the number of pulses in the work counter 29 becomes the same as the number of pulses in the pitch number counter 28 (step P40). When they are the same, a reverse rotation signal is given to the motor drive system 26 to return the grip bar 10 to its original position (step P41), the work counter 29 is initialized (step P42), and the number counter 30 is updated by one. (Step P43). Then, at the next step P44, it is judged whether the number counter 30 reaches "40" or the hand switch S3 is turned on. If neither is satisfied, the pitch number counter 28 is updated by 2 mm, that is, one pulse number. (Step P45) and return to Step P38, and repeat the operations up to Step P44. Then, when the number counter 30 is "40" or when the trainee wishes to skip the 40 times of the above-mentioned operations in the middle of the operation, when an interrupt occurs due to turning on the hand switch S3, the next step P46 Then, the frequency counter 30 is initialized and the driving pulse having a long pulse width is supplied from the control unit 18 to the buzzer 27 through the third output port 21 to generate a long beeping sound (step P47). This completes the training and moves to the next ending operation.

A reverse rotation signal and a signal indicating high-speed operation are given to the motor drive system 26 to return the grip bar 10 to its original position at high speed (step P48). Then, it is determined whether 10 seconds have passed from the buzzer output (step P47) or whether the hand switch S3 is turned on (steps P49 and 2P50). The above judgment operation is repeated until either of them is satisfied. When a timer interrupt of 10 seconds has elapsed or a hand-on switch-on interrupt occurs, the routine proceeds to the next step P51, where a forward rotation signal is given to the motor drive system 26 and the grip bar 10 is moved forward. At the same time, the number of detection pulses from the optical sensor 24 is registered and updated in the work counter 29 (step P52). The operations of steps P51 and P52 are performed until the number of pulses in the work counter 29 becomes equal to the number of pulses in the fixed data 31. The fixed data 31 stores the number of pulses corresponding to the distance from the last retracted position of the grip bar 10 to the position of the foot pad 3, and the grip bar 10 is moved to the position of the foot plate 3 by the above operation. Go to and stop.

After that, the number of pulses in the pitch number counter 28 and the number of pulses in the fixed data 31 are read and the difference between them is calculated, and the difference data is converted into a unit of centimeter (step P54). The calculation result is displayed on the display unit 25 from the control unit 18 via the first output port 19 (step P55). That is, this calculation result indicates the relative distance between the forward movement position of the grip bar 10 and the position of the footrest plate 3 obtained by training, and the gripstick rod 10 moves forward from the position of the footrest plate 3 during training. If yes, plus is displayed, if negative, minus is displayed at the same time.

When the user feels tired during the training operation, the return switch S4 on the right side of the bench body 1 is released by releasing the hand from the grip bar 10 to generate a return switch on interrupt (step P101). ), The work counter 29 is initialized based on this interrupt (step P102), the control is transferred to step P46, and then the ending operation is performed.
