It is an object of the present invention to provide a moving body system which can determine the moving position of a vehicle, stacker crane, or other moving body wherever on a moving path having a branching portion or a joining portion the moving body is, the system being able to precisely stop the moving body at any position and enabling the moving body to move fast to a stop position. A moving body system includes a vehicle 1 moving along running rails 2, 2 constituting a moving path having a joining portion and a detected member 20 laid along the running rails 2, 2. The detected member 20 includes a large number of mark members 21, 21, . . . in a direction in which the vehicle 1 moves. The vehicle 1 includes a first detecting sensor 11 and a second detecting sensor 12 which detect the mark members of the detected member 20.

The invention claimed is: 1. A moving body system comprising: a moving body that moves along a moving path and a detected member laid along the moving path, wherein the detected member comprises a plurality of mark members in a direction in which the moving body moves, wherein the moving body comprises detecting means for detecting the mark members of the detected member, wherein each of the mark members comprises a detected portion detected by the detecting means and a non-detected portion not detected by the detecting means, wherein the detected member is configured as comb teeth in which a comb tooth portion is the detected portion and a void between the comb teeth is the non-detected portion, wherein the width of the detected portion in the moving direction of the moving body is equal to that of the non-detected portion in the moving direction of the moving body, wherein the detecting means comprises a first detecting means and a second detecting means arranged in the moving direction of the moving body, and wherein the moving path of the moving body has a branching portion that branches to at least two paths, an additional detected member is provided on each of the branching paths and the moving body is provided with additional detecting means for detecting the additional detected members. 2. A moving body system comprising: a moving body that moves along a moving path and a detected member laid along the moving path, wherein the detected member comprises a plurality of mark members in a direction in which the moving body moves, wherein the moving body comprises detecting means for detecting the mark members of the detected member, wherein each of the mark members comprises a detected portion detected by the detecting means and a non-detected portion not detected by the detecting means, wherein the detected member is configured as comb teeth in which a comb tooth portion is the detected portion and a void between the comb teeth is the non-detected portion, the width of the detected portion in the moving direction of the moving body is equal to that of the non-detected portion in the moving direction of the moving body, wherein the detecting means comprises a first detecting means and a second detecting means arranged in the moving direction of the moving body, and wherein the moving path has a joining portion in which at least two paths are joined together, and a second detected member is provided on a resulting path so that the second detecting means can detect the second detected member. 3. The moving body system according to claim 1 or claim 2, wherein the detected members have positional information, and the detecting means reads the positional information from the detected members. 4. The moving body system according to claim 1 or claim 2, wherein the moving body comprises: an encoder that measures a moving distance and a control means for controlling the moving speed of the moving body by determining a moving position while using the detecting means to detect the mark members of the detected member until the mark member of the detected member located immediately before a stop target position is reached, wherein between the mark member located immediately before the stop target position and the stop target position, the control means uses the encoder to measure the moving distance from the mark member located immediately before the stop target position to the stop target position, and wherein the control means stops the moving body at the stop target position. 5. The moving body system according to claim 4, wherein the control means resets the measurement of the moving distance by the encoder to an origin every time the detecting member detects a detecting point on the mark member of the detected member.
