  As described above, in recent years, a case of an automatic ticket gate having a case width of 160 mm has been proposed. When a geared motor that opens and closes a door is built in the casing of the automatic ticket gate, it is usually necessary to newly design a small geared motor that matches the dimensions of the casing. However, in reality, there is no need to newly prepare a high-cost small geared motor, but the 80-square geared motor used in the conventional automatic ticket gate can be used, and the automatic ticket gate with a narrow housing width is used. There is a need to reduce the cost of manufacturing machines.

  In view of the above problems, the object of the present invention is to improve the mounting layout in a ticket gate housing with a narrow housing width so that a geared motor with an 80-square size can be mounted compactly, and has been used conventionally. An object of the present invention is to provide a door opening / closing mechanism of an automatic ticket gate that can use a square geared motor and can reduce production costs.

  The door opening / closing mechanism of the automatic ticket gate according to the present invention is configured as follows in order to achieve the above object.

  A door opening / closing mechanism of a first automatic ticket gate (corresponding to claim 1) is provided in an automatic ticket gate in which a geared motor with a motor shaft and a gear head shaft shifted is installed in a housing for opening and closing the door. The position of the geared motor is selected so that the position of the gearhead shaft and the position of the gear head shaft are in the vertical direction, and the geared motor is installed close to the door shaft of the door.

  The door opening / closing mechanism of the above-mentioned automatic ticket gate takes into account the gap that exists between the motor shaft and the gear head shaft when incorporating a motor unit (geared motor) into the case of a new narrow automatic ticket gate. Thus, the layout was determined, and the geared motor was installed close to the door shaft of the door, making it possible to install it in a narrow casing.

  In the door opening / closing mechanism of the second automatic ticket gate (corresponding to claim 2), preferably, the rotation operation of the gear head shaft is converted into the rotation operation of the door shaft via the link mechanism. The rotor is attached to the gear head shaft, the crank is attached to the door shaft, and the connecting rod connects the rotor and the crank.

  The door opening / closing mechanism of the third automatic ticket checker (corresponding to claim 3) is preferably configured such that in the above-described configuration, the arrangement posture of the rotor in the door opening operation state is approached in the vertical direction, and the door opening operation state is The mounting angle between the rotor and the connecting rod in the above is relatively large. According to this configuration, since the opening angle of the rotor and the connecting rod is increased, the loss of the starting force at the time of starting can be reduced, and power saving can be achieved.

  The door opening / closing mechanism of the fourth automatic ticket gate (corresponding to claim 4) is preferably characterized in that a rib for reinforcing the structure for attaching the geared motor is provided in the housing in the above configuration.

  In the fifth automatic ticket gate, the door opening / closing mechanism (corresponding to claim 5) preferably has a trigger solenoid for closing the door in the case of an emergency at a position above the geared motor. It is characterized by being buried inside. With this configuration, the overall height of the door driving device can be pushed and compactly incorporated in the case of the ticket gate body.

The door opening / closing mechanism of the sixth automatic ticket gate (corresponding to claim 6) preferably has a ring-shaped connecting portion at the front portion and the base portion, and a portion between them has a necessary thickness as a whole. The connecting rod formed as a portion having a connecting rod, the rotor connected to the ring-shaped connecting portion at the tip of the connecting rod, and the crank connected to the ring-shaped connecting portion at the base of the connecting rod are included in one plane as a whole. It is implemented based on such a layout . According to this configuration, when the connecting rod is reciprocally moved by the rotating operation of the rotor, the rotating operation of the crank around the door shaft can be smoothly performed.

  According to the present invention, when mounting a geared motor conventionally used in the case of a narrow new automatic ticket gate, the layout is determined in consideration of the deviation existing between the motor shaft and the gear head shaft in the geared motor, As a result, the geared motor can be installed close to the door shaft of the door and installed in a narrow casing. In particular, the mounting layout in the case of a narrow ticket gate can be improved so that a geared motor with a size of 80 can be mounted compactly. Can be reduced.

A link mechanism (not shown) is disposed in the space below the upper frame 24b. This link mechanism has a function of transmitting the emergency operation of the trigger solenoid device 25 to the door shaft 15B. A hole 24c-1 corresponding to the gear head shaft 22B-1 is formed in the front end frame 24c. It can face the tip of the gear head 22B-1 through the hole 24c-1.

  A link mechanism based on a door opening / closing mechanism is provided between the gear head shaft 22B-1 of the geared motor 22 and the door shaft 15B. This link mechanism has a function of converting the rotation operation of the gear head shaft 22B-1 into the rotation operation of the door shaft 15B. The link mechanism includes a rotor 31, a connecting rod 32, a crank 33, a coil spring 34, and the like. In FIG. 3, the coil spring 34 is not shown.

  As shown in FIGS. 2 and 3, the lower end (base end) of the rotor 31 is coupled to the gear head shaft 22B-1, and the rotor 31 has a small angle with the vertical line 23 and is a relatively standing angle. In the state, it is attached to the gear head shaft 22B. The rotor 31 rotates so as to reciprocate within a range of angles set around its lower end in accordance with the rotation operation of the gear head shaft 22B-1.
