摘要： PURPOSE: To perform control for a plurality of transmitting passages and control for a communication device with a simple structure by providing communication controllers each of which is composed of a microcomputer and a dual port RAM in a machine room and on a car. CONSTITUTION: A CPU 1a in a communication controller 1 reads the communication starting data from the specific area of a dual port RAM1b and judges whether the communication is to be started or not from the data. If the communication is to be started, light space transmitting devices 4, 5 are sequentially started, and the transmit data is read from the specific area of the dual port RAM1b and sent to the light space transmitting device 4. The receive data is read from the light space transmitting device 4 and written into the specific area of the dual port RAM1b. The transmit data is read from the specific area of the dual port RAM1b and sent to the light space transmitting device 5. The receive data is read from the light space transmitting device 5 and written into the specific area of the dual port RAM1b. Similarly, the abovementioned operation is repeated.

摘要： PURPOSE: To attain stable signal transmission by arranging space light transmission devices driftingly in the height direction of a car so that the space light transmission device installed in a car is not affected by the light beam from the space light transmission device installed in an adjacent car. CONSTITUTION: When space light transmission devices 2, 2a are drifted in the height direction, the distance L between the space light transmission devices 2, 2a can be made larger than the distance between both devices installed at the same height, and the space light transmission devices 2, 2a can be installed without widening the space 12. The space light transmission devices 2, 2a are vertically inverted, there is no problem when the light beams 10, 11 a from the projection sections of the space light transmission devices 2, 2a are overlapped. The light beam 10 is radiated to the light reception section of the space light transmission device 2, the light beams 10, 11 a are opposite in the direction of radiation, the light beam 10 is not directly fed to the light reception section of the space light transmission device 2a, and there is no problem in data transmission.

摘要： PURPOSE:To prevent wear of an elevator car guide roller and generation of cable contacting noise by pressing an elevator control cable in the cable direction on the pit side with the lower part of the car using an arm furnished in the lower part of the car, and making the cable hanging dimension smaller than the free hang dimension. CONSTITUTION:An elevator control cable 2 is installed near the center of gravity of an elevator car 1, and a cable guide device 4 is furnished in the lower part of the car 1 for pressing the cable 2 in the cable direction on the pit side. When the car 1 sinks to get the 1b position, elevator controlling cable 2b is pressed by the cable guide device 4 so that the hanging dimension of the cable is changed, and thereby the car 1b is prevented from touching the cable 2b. Because the risk of the car inclining is eliminated, wear of a car guide roller caused by the car lying eccentrically is precluded.

摘要： PURPOSE:To simplify a system constitution by calculating the load value based on the detection signal from a load detector installed on a car, and multiplex- transmitting this load value together with other signals to a machine room as digital signals at the request from the machine room. CONSTITUTION:One of car load detectors 5, 5a, 5b is selected by a selective switching circuit 15 and connected to an A/D converter 2e. The A/D converter 2e converts the output signal of the selected car load detector into the digital signal. This signal is converted into the load value and stored in a RAM 2c. The total load of a car is calculated based on the load values from all load detectors provided in the car, and it is stored in the RAM 2c. When the execution of the interruption handling requiring the car load value is requested from an elevator control device 9, the total load value of the car stored in the RAM 2c is read out, and it is transmitted to the elevator control device 9 together with other data to be transmitted.

摘要： PURPOSE:To provide a safety signal wireless transmitting system by which transmission of a signal and operation and control of an elevator can be carried out without damaging any safety of the elevator. CONSTITUTION:A safety device signal inputting circuit 2 and a wireless transmitter 1 transmitting only the carrier wave are provided on a car side. The wireless transmitter 1 normally transmits the carrier wave and is controlled so as to stop the transmission of the carrier wave when action of a safety device is detected. A receiver 21 receiving the carrier wave is provided on a machine room side, and a microcomputer 22 for communication outputs a signal to an elevator control device 48 so that it stops the elevator. A transmission path for a safety device signal carrying out signal transmission in a car cage safety device constructed in this way is arranged independently of a transmission path for general device output. In this way, an operating condition of the safety device is transmitted only by on/off of the wireless carrier wave, and no information is provided in the wireless signal, so that highly reliable transmission can be carried out.

摘要： PURPOSE:To provide a signal transmission device for an elevator without a tail cord in which a spatial transmission distance is kept at a short fixed distance even when a traveling range of the elevator becomes a long travel, highly reliable transmission can be achieved, and working manhours are decreased to realize cost reduction. CONSTITUTION:Signal transmission between elevator cars 5a, 5b and machine rooms 4a, 4b is conducted via a transmission cable 1 capable of contactless transmission and arranged in an elevator penthouse. This transmission cable 1 is used in common for at least two adjoining elevators, A and B, and is also used in common for signal transmission between the machine rooms 4a, 4b and hall control boards 8-1, 8-m, 8-n. Accordingly, a cable for one car can provide transmission for two cars, and one transmission cable can be used in common to transmit signals between the machine room and the car, and between the machine room and a hall to reduce the number of cables so as to reduce working manhours and a cost.

摘要： PURPOSE:To enable a close coupling condition to be secured by providing a leading guide which can stably maintains a noncontact condition between a coupling means extended in the direction of a close coupling cable in a car and thereby making a distance and a space between a coupler and a close cable constant even if a cable vibrates or even if the cable is swung and bent. CONSTITUTION:A close cable 1 is installed so as to be fixed between the uppermost and the lowermost floors while tension is applied in the direction that an elevator car 7 is moved up and down by a messenger wire 2 attached to the close cable 1. A coupler 5 to be coupled with the close cable 1 is installed onto the cage 7 via a damper 6, and a leading guide 4 guiding the close cable 1 is provided for the coupler 5. By this constitution, even if the close cable 1 is out of the lift line of the cage 7 when the cage 7 is moved up and down, the close cable 1 at the place of the coupler 5 is guided by the leading guide 4 at all times to a place where the close cable is coupled with the face of the coupler 5. Therefore, stable coupling can thereby be made even if the cage is swung and inclined or even if the cable 1 is swing and the like.
