Is an OR element, MV is a multivibrator that outputs a clock pulse signal, CT is a clock call signal that is input and reaches a predetermined value, that is, the maintenance service switch 12 is operated, and a car call button (see FIG. 3). If the car call button 3) is pressed and the RV flip-flop FF1 is set, the RS flip-flops FF1 to FF9 are reset after a lapse of a predetermined period of time (a period of time during which the maintenance service operation is completed each time). It is a counter that outputs a signal. The other internal circuit configurations of the distance signal generators 21 and 22 are exactly the same as those of the distance signal generator 23 surrounded by the alternate long and short dash line, and are not shown.

Next, the operation of the device of the present invention will be described.

Now, let's take as an example the case where a service person who has boarded an elevator car wants to raise the elevator car by 333 mm.First, the service person turns on the maintenance service switch 12 on the car operation panel and sets the distance signal generators 21-23. After applying the positive power supply voltage + V to the RS flip-flops FF1 to FF9,
Operate the car call button 3 three times to indicate the 100th position of the target movement distance. First, when the car call button 3 is pressed once, the RS flip-flop is closed by closing the normally open contact 3a in FIG.
Since a high-level signal is input to the input terminal S _{1 of} FF1, the high level is input to the output terminal Q ₁ of the RS flip-flop FF1.
A level signal is output and the state is maintained, the gate of the AND element AND1 is opened, the gate of the AND element AND9 is opened, and the clock pulse signal generated by the multivibrator MV is input to the counter CT to measure the time. Let it start.

Next, when the car call button 3 is pressed once more, the Hig signal is applied to the input terminal S ₂ of the RS flip-flop FF2 through the AND element AND1.
The signal of the h level is input, and a high level signal is output to the output terminal Q ₂ of the RS flip-flop FF2 to maintain that state and to open the gate of the AND element AND2. Then, press the car call button 3 once more (total 3 times)
Then, a high level signal is input to the input terminal S ₃ of the RS flip-flop FF3 through the AND element AND2, and a high level signal is output to the output terminal Q ₃ of the RS flip-flop FF3 to maintain the state.

Next, when the service person operates the car call button 2 three times to instruct the tens digit of the target movement distance, the RS flip-flop (not shown) in the distance signal generator 22 is operated in the same manner as described above.
When the car call button 1 for instructing the ones digit of the target moving distance is operated three times, the RS flip-flop (not shown) in the distance signal generator 21 is operated in the same manner. The output signal 21a (2 of the RS flip-flop in the distance signal generators 21 to 23

A pulse is input to C ₉ and the output state of the RS flip-flop at that time appears as it is at the output terminal of the D flip-flop (Q _{11 to} Q _{19 in} FIG. 3) and the state is maintained. In terms of this case, 21b ₁ of the output signal 21b~23b the distance signal generator _{21~23, 21b 2, 21b 3,} 22b 1, 22b 2, 22b 3,
Only 23b ₁ , 23b ₂ and 23b ₃ are supplied with a high level signal to the encoder 30 to generate a binary coded signal 30a corresponding to the target moving distance. On the other hand, when the ascending operation button 13 is operated, the elevator car starts ascending movement by a well-known speed control device, and the pulse generator 41 outputs the pulse signal 41a according to the moving distance of the elevator car. Therefore, the subtraction device 43 calculates the distance of the elevator car to the target point one by one, and when this distance reaches a predetermined value, that is, the deceleration start distance, the subtraction device 43 transmits the deceleration command 43a to the speed control device. The car is decelerated, and if this distance becomes zero, a stop command 43b is output to stop the elevator car. Then, when the elevator car stops, for example, a stop signal 40a generated when a brake (not shown) of the hoisting machine is actuated is input to the distance signal generators 21 to 23, and an OR element (symbol OR in FIG. 3 is indicated. RS flip-flop and D flip-flop (3rd

Next, the operation will be described.

For example, if a service person who got in the elevator car wants to raise the elevator car by 321 mm,
First of all, the service person is the maintenance service switch of the car operation panel.
After operating 12 to open the gates of the AND devices AND21 to AND30, press the car call button 3 corresponding to the numeral "3" at the tens digit of the target movement distance. Then, the high level signal input to the AND element AND13 by closing the normally open contact 3a is

Next, when the serviceman presses the car call button 2 corresponding to the digit "2" of the tens digit of the target movement distance, the normally open contact 2a is closed. The high level signal input to the AND element AND12 by the AND is input to the AND element AND32 with the L active input terminal via the AND12, the resistor r ₂₂ , the capacitor C ₂ , and the L active input terminal, and then the service person calls the car. Immediately after the button 2 is released, the L active input is input for a short time while the capacitor C ₂ is being charged (the time determined by the time constant of the resistor r ₂₂ and the capacitor C ₂ due to the opening of the normally open contact 2a). The logical product element AND32 with a terminal outputs a high level signal, and this signal is input to the encoder E2 through the logical product element AND22, and the output terminals d ₂ , c ₂ , b ₂ and a ₂ of the encoder E2 are decimal 2 Generates a binary coded decimal signal "0010" corresponding to Then, the binary signals are input to the OR elements OR1, OR3, OR4, OR5, respectively, and output as they are, and the capacitor C ₁₂ is charged with a high level signal (the input of the OR element OR3 is Low.
Even if it goes to the level state, the high level state is maintained until the time determined by the time constant of the resistor r ₃₂ and the capacitor C ₁₂ elapses).

Even after that, the high level state is maintained until the time determined by the time constant of the resistor r ₃₁ and the capacitor C ₁₁ elapses).

Here, at the moment when the car call button 1 is released, only the output line P _{1 of the} AND element AND21 (the output lines P _{2 to} P ₁₀ of the AND elements AND22 to 30 remain in the low level state) is in the high level state.

By the way, the car call button of the elevator is not limited to one provided on each floor independently, but it is also configured, for example, like a ten-key keyboard, and it is extremely easy to change the circuit to similarly set the distance.

Further, since the display means 15 is for the service person to visually check the target moving distance set value, even if the display means 15 is omitted, it does not particularly hinder the solution of the basic problem of the present invention. Alternatively, instead of providing the special display means 15 (especially in the second embodiment), it is also possible to divert the tell tale displaying the registration of the car call button which is normally installed, and it is also possible to use a normal elevator. The car position display device can also be used and is not limited to the embodiment.
