 11 to 14 show an access safety device according to a second embodiment of the present invention.
 The entrance safety device 20 according to the second embodiment includes: an entrance part 21 , an entrance support part 22 , a fixing part 23 , two pairs of connection parts 24 , a pulling spring 25 and a safety switch 26 . The inlet member 21 fits in the rail / handrail hole 7 on the front panel 6c with only its top end protruding (approximately 5mm) from the protrusion 6d on the front panel 6c. The inlet support member 22 is fixed to the rear end portion of the inlet member 21 . The fixing member 23 is fixed to the escalator main body (conveyor main body). The connection members 24 are configured as inlet movement guides for connecting the inlet support members 22 to the fixed members 23, respectively. The tension spring 25 serves as biasing means for biasing the inlet part 21 in a direction opposite to the moving direction h of the moving armrest 5 . The safet...
