Description

[Detailed Description of the Invention] This invention relates to a detection device for detecting the operation of a shutter installed on a customer service area such as an automatic ticket adjustment machine or an automatic teller machine.

For example, in the case of an automatic ticket adjustment machine, a first shutter 2 is provided on the customer service side of a terminal 1 shown in FIG. 1, a safety device 3 is provided at the lower end, and a rack 4 is provided on the back side.

The first shutter 2 detects the presence of a person on the customer service area using a treadle, etc., and the motor 7 rotates the pinion 5 that meshes with the rack 4 to open the first shutter 2. After that, insert your hand through the opening and get on board. The ticket is presented on the stopped conveyor belt 6.

There is a second shutter 8 in the back that can be opened and closed to regulate the position of the ticket and prevent it from being taken out, and the observation area between it and the first shutter 2 is an illuminator 9 for lighting and imaging of the ticket. ITV camera 1 is transmitted to the central monitoring room.
0 is provided.

When the shutter is removed, the photosensor 11 located next to the first shutter 2 detects this, closes the first shutter 2 and performs the necessary processing, and when the processing is completed, the second shutter 8 opens and drives the motor 22 to start the belt conveyor. 6 is moved to store the paid tickets in the discontinued ticket box 13.

Note that the first shutter 2 placed on the customer service surface must not injure hands when closed.

Therefore, while the hand is under the first shutter 2, the first shutter 2 is not closed to the feeder and is kept open, and the photosensor 11 monitors the movement of the hand, and the signal is used to It controls shutter 2.

For this purpose, as shown in FIG. 2, the photosensor 11 has a plurality of light emitting elements and light receiving elements disposed facing each other parallel to the shutter along the guide L/Ls 14 on both sides of the first shutter 2.

Since the photosensor 11 is placed within easy reach, it may be difficult to block the functional surface of the photosensor 11 with, for example, gum, which may cause an abnormality in the device.

Therefore, in order to prevent such mischief, it is necessary to make the sensor function as a sensor without people noticing that it is attached.

Incidentally, in the past, a sensor mounting and detection method as shown in FIGS. 3 and 4 has been used.

FIG. 3 shows an example using a photosensor 11, in which the first shutter 2 moves up and down while being guided by, for example, claws (not shown) that engage with grooves in guide rails 14 provided on both sides thereof.

Side guide plates 15 stand up on both sides of the belt conveyor 6.

A plurality of facing holes 17 for a light emitting element and a light receiving element are bored in the side guy F plate 15 along the guide rail 14.

Photosensors 11 loaded in holding blocks 16 having respective light emitting or light receiving holes 17a are screwed to guide rails 14 so that light from the light emitting elements reaches the light receiving elements through holes 17.

In this way, the photosensors 11 are arranged in series so that wherever the hand is within the opening of the first shutter 2, the location of the hand can be detected.

In this case, the fact that the sensor 11 is attached and its attachment position can be easily seen through the hole 17 of the side guy F plate 15.

Therefore, it is easy to induce mischievous acts such as blocking the hole 17 with gal, etc.

FIG. 4 shows an example of detection using a microswitch, in which a slide piece 3a that supports the safety device 3 at the bottom of the first shutter 2 with a spring (not shown) and is movable up and down is attached to the bottom of the first shutter 2. A microswitch 18 is attached to the top of the slide piece 3a so that when a hand touches the bottom of the slide piece 3a, the microswitch 18 operates and opens the first shutter 2. In this case, a certain amount of pressure is applied to the human hand. It is fine if your hand is near the center of slide piece 3a, but if your hand is on one side, slide piece 3
3a' as shown in the figure, the disadvantage is that the guide rail 14 may be distorted, and the microswitch may not operate, leading to a situation in which the user's hand is caught.

From this point of view, it is an object of the present invention to provide a detection device for shutter operation control that eliminates the above-mentioned drawbacks and functions as a sensor without people noticing that the sensor is attached.

According to the present invention, a large translucent cover plate that can transmit light is arranged in front of the hole of the holding block that has a light emitting or light receiving hole loaded with a photosensor so as to cover the peripheral part of the holding block. They are distant relatives.

The configuration will be described below with reference to FIG. 5 showing an example.

The illustrated idle rails 14 are arranged symmetrically on both sides of the partially shown first shutter 2.

A plurality of photosensors 11 are attached to a guide rail 14 or a side guide plate 15' to be described later so that the light beams of the photosensors 11 cross in parallel inside the first shutter 2 near the opening.

At this time, when the light emitting element loaded in the holding block 16 having the light projecting hole 17a or the light receiving hole 17a is attached to the left guide rail 14, for example, the light receiving element is attached to the right guide rail 14.

The illustration shows a case in which the holding block 16 is screwed to the guide rail 14, and a translucent cover plate 19 is provided to block the front surface of each hole 17a of the holding block 16.

This cover plate 19 is made of a semi-transparent acrylic plate or glass plate, etc., which does not block the light beam and does not allow people to see the photosensor 11 through the cover plate 19, and the photosensor itself is also made of a highly sensitive one. use.

A side guide plate 15' is arranged adjacent to the cover plate 19.

A photosensor can also be attached to this side guide plate 15' via a holding block 16.

As described above, according to the present invention, since the front surface of the sensor for controlling the opening/closing operation of the first shutter is covered with a translucent cover plate, the location of the sensor cannot be visually seen, and it is difficult to see where the sensor is, so that it may be difficult to see where the sensor is. actions can be eliminated.

Furthermore, since the cover plate itself does not block the light beam, the detection effect is not impaired.

Therefore, by attaching a simple translucent cover plate to the front of the sensor, the tampering of this type of detection device using conventional photosensors can be avoided and the above-mentioned disadvantages of microswitches are avoided.

Although the description has been made regarding an automatic ticket adjustment machine, the present invention is also suitable as a detection device for controlling the opening/closing operation of a shutter of an apparatus having a shutter on the customer service side, such as an automatic teller machine, an exchange machine, or a vending machine.
