Description

  The present invention relates to an opening / closing door device and a coin handling machine.

  For example, there is a vending machine as a coin handling machine that pays out coins from the inside of the machine so that the coins can be taken out (see Patent Document 1, for example).

In a coin handling machine such as a vending machine, a money changer, a coin depositing / dispensing machine, a coin depositing / dispensing machine, coins are fed out from the machine to such a dispensing outlet for deposit return or withdrawal. In order to prevent the coin from being thrown out of the machine, the door is provided with a swingable door so that, for example, a change in state of the door from the closed state to the open state is detected. Thus, it is confirmed that the coins fed out to the outlet are taken out of the machine.

  As described above, in order to detect a change in the state of the open / close door from the closed state to the open state, a reflective optical sensor may be provided to face the open / close door in the closed state. In this case, the reflective optical sensor detects that the open / close door is closed when receiving light reflected from the open / close door and receiving the reflected light from the open / close door. When it disappears, it detects that the door is opened. With such a reflection type optical sensor, even if the opening / closing door is swung by a slight angle from the closed state, the reflected light is shifted and cannot be detected, so it is detected whether the opening / closing door is reliably opened. It was difficult to do.

  Accordingly, an object of the present invention is to provide an open / close door device and a coin handling machine that can detect that the open / close door is reliably opened from the closed state even when a reflective optical sensor is used.

To achieve the above object, the present invention includes a door which is swingable about a pivot shaft, disposed opposite to the rotating of the door to the door in a closed state according to claim 1 A reflective optical sensor composed of a light emitting element and a light receiving element for detecting an open / closed state by swinging about a moving axis, and the opening and closing when the light receiving element is in a state of receiving reflected light by emitting light from the light emitting element. A control unit that determines that the door is in a closed state, and causes the light emitting element to emit light and determines that the door is in an open state when the light receiving element is not receiving reflected light. A retroreflective sheet is provided on a surface of the closed door that faces the reflective optical sensor, and the reflective optical sensor is in a closed state where the angle of the open / close door is 0 degrees. The light emitting element is swung in the opening direction up to a predetermined angle. When the light is emitted, the light receiving element receives the reflected light by the retroreflective sheet, and if the angle of the door exceeds the predetermined angle, the light receiving element does not receive the reflected light even if the light emitting element emits light. It is characterized by a state.

According to a second aspect of the present invention, there is provided a payout opening through which coins can be taken out from the inside of the machine , an open / close door that opens and closes the payout opening and that can swing around a rotation shaft, and the open / close door in the closed state. A reflective optical sensor composed of a light emitting element and a light receiving element that detects the open / closed state by swinging around the pivot axis of the opening and closing door, and the light receiving element emits light. When the reflected light is received, the door is determined to be closed, and when the light emitting element emits light and the light receiving element does not receive the reflected light, the door is open. A coin handling machine having a control unit for determining , wherein a retroreflective sheet is provided on a surface of the closed door facing the reflective optical sensor, and the reflective optical sensor is Predetermined angle from the closed state where the door angle is 0 degrees When the light emitting element emits light while swinging in the open direction, the light receiving element is in a state of receiving reflected light by the retroreflective sheet, and when the angle of the open / close door exceeds the predetermined angle, the light emitting element is It is characterized in that the light receiving element does not receive reflected light even if light is emitted .

  According to the first aspect of the present invention, since the retroreflective sheet is provided on the surface of the closed door that faces the reflective optical sensor, the open / close door only swings by a slight angle from the closed state. In this case, the reflected light from the retroreflective sheet is received by the reflective optical sensor without shifting, and the reflected light from the retroreflective sheet is shifted and reflected when the open / close door is reliably opened. Is not received by the mold optical sensor. Therefore, even when a reflective optical sensor is used, it can be detected that the open / close door has been reliably opened from the closed state.

Can do.

An opening / closing door apparatus according to an embodiment of the present invention and a coin handling machine using the same will be described below with reference to the drawings.
A coin handling machine 1 according to the present embodiment shown in FIG. 1 is a coin depositing machine installed in a store of a financial institution such as a bank. It constitutes a money handling machine.

  Normally, a store of a financial institution is divided by a partition wall W into a clerk side space Sa in which customers are restricted and only a clerk or other clerk can come and go, and a customer side space Sb such as a lobby in which a customer can go and go. Yes.

  And the coin handling machine 1 of this embodiment will be arrange | positioned ranging over these staff side space Sa and customer side space Sb. When the clerk side space Sa side from the partition wall W is the clerk side region portion 11A and the customer side space Sb side from the partition wall W is the customer side region portion 11B, the coin handling machine 1 is connected to the clerk side region portion 11A and the customer side region portion 11B. An internal mechanism is shared by the side region portion 11B to perform processing on coins. On the upper part of the coin handling machine 1, a partition plate 13 that partitions the clerk side region 11A and the customer side region 11B is erected. In the coin handling machine 1, the partition wall W and the partition plate 13 make it impossible to operate the clerk side region portion 11A from the customer side space Sb, and the customer side region portion 11B cannot be operated from the clerk side space Sa side. ing. In the following, the clerk side of the coin handling machine 1 is the front side of the fuselage (one side of the fuselage), and the customer side is the rear side of the fuselage (the other side of the fuselage).

  The coin handling machine 1 can perform various processing such as deposit processing of rose coins and withdrawal processing of rose coins in the clerk side region 11A on the front side of the fuselage, and the customer side region on the rear side of the fuselage. In 11B, only the process of depositing loose coins is possible. That is, the coin handling machine 1 functions as a lobby depositing machine capable of depositing money for a customer, and functions as a depositing machine capable of various processes such as depositing / dispensing processing for an attendant.

  In the clerk side area 11A on the front side of the aircraft, the clerk side insertion port 16 on the one side that accepts deposit of rose coins by the clerk during the deposit process on the clerk side, and improper deposit of fake coins etc. from the received rose coins A deposit reject box 17 that is detachable from the fuselage 10 and rejects the coins so that the coins can be withdrawn to the attendant during withdrawal processing of the rose coins. A dispensing box 18 that can be attached to and detached from the machine 10 is provided.

  In the customer side area portion 11B, the customer side slot 21 for receiving the deposit of rose coins by the customer at the time of deposit processing on the customer side, and the coins identified as unsuitable coins among the received rose coins A deposit reject port (feed port) 22 is provided so that the customer can take it out, and an alarm lamp 23 is provided in the vicinity of the deposit reject port 22 to notify the presence or absence of coins in the deposit reject port 22. Yes.

  As shown in FIG. 2, the deposit reject port 22 has a bottom plate portion 25 that extends substantially horizontally and a substantially cylindrical surrounding wall portion 26 that rises from the peripheral edge of the bottom plate portion 25. An opening 27 that opens to the outside of the machine is formed in the lower part on the side. In addition, a synthetic resin opening / closing door 30 that opens and closes the opening 27 is supported at the deposit reject port 22 so as to be swingable around the upper rotation shaft 31. The opening / closing door 30 is lowered vertically by its own weight. Then, the opening 27 is closed. Further, when the door 30 is pushed backward, it swings around the rotation shaft 31 to expose the bottom plate portion 25 at the opening 27, and in this state, coins are taken out of the machine.

  A reflective optical sensor 33 for detecting the open / close state of the open / close door 30 is provided on the surface of the surrounding wall portion 26 of the deposit reject port 22 facing the open / close door 30 facing the closed state. Has been placed. As conceptually shown in FIG. 3, the reflective optical sensor 33 includes a light emitting element 34 and a light receiving element 35, emits light from the light emitting element 34 toward the opening / closing door 30, and the opening / closing door 30. A light receiving element 35 is provided so as to receive reflected light whose light axis matches the optical axis when is closed. Here, the open / close door device 38 is configured by the open / close door 30 and the reflective optical sensor 33. The reflective optical sensor 33 is connected to a control unit (not shown), and the control unit emits light from the light emitting element 34 of the reflective optical sensor 33 toward the open / close door 30 and receives the reflected light at that time. If the element 35 receives light, the open / close door 30 is in a closed state, and if no light can be received, it is determined that the open / close door 30 is in an open state.

  In the open / close door device 38, the retroreflective sheet 40 is attached to the surface of the open / close door 30 in the closed state facing the reflective optical sensor 33. The retroreflective sheet 40 is a reflective sheet having a structure in which fine round glass beads are embedded in, for example, a transparent synthetic resin film. Of course, the rectilinear sheet shown in FIG. Light incident at an angle with respect to the direction perpendicular to the plane shown in 3 (b) is reflected in the incident direction by the action of the glass beads.

  When the angle with respect to the direction orthogonal to the incident light exceeds a predetermined angle, the retroreflective sheet 40 becomes difficult to retroreflect, and this is used to change the open / close door 30 from the closed state to the open state. To detect. That is, since the retroreflective sheet 40 performs retroreflection with respect to incident light while the angle θ of the open / close door 30 swings in the opening direction from the closed state where the angle θ is 0 degree to the predetermined angle θ1, the light emitting element 34 is in the meantime. When the light is emitted, the light receiving element 34 receives reflected light, and in this state, the control unit determines that the open / close door 30 is in a closed state. Next, when the angle θ of the open / close door 30 exceeds the predetermined angle θ1, the retroreflective sheet 40 does not perform retroreflection with respect to incident light. Therefore, even if the light emitting element 34 emits light, the light receiving element 35 emits reflected light. In this state, the control unit determines that the door 30 has been opened. Next, when the angle θ of the open / close door 30 returns to within the predetermined angle θ1, the retroreflective sheet 40 performs retroreflection with respect to incident light. Therefore, when the light emitting element 34 emits light, the light receiving element 35 reflects the light. In this state, the control unit determines that the door 30 is closed again.

  When the customer inserts coins into the customer insertion slot 21 of the coin handling machine 1 when the customer deposits coins, the control unit separates and conveys the inserted coins one by one. The seeds and the like are identified and counted, and the coins identified as fake coins, that is, coins that are not suitable for depositing based on the identification result, are sent to the deposit reject port 22. Further, true coins, that is, coins identified as deposit appropriate coins, are classified according to money type, temporarily stored, and stored in the machine after approval.

  At this time, the control unit collects the reject coins generated in one customer-side deposit process to the deposit reject port 22 at the same time as the coins are fed to the deposit reject port 22 and simultaneously to the deposit reject port 22. Is informed to the customer by blinking an alarm lamp 23 provided in the vicinity of the deposit reject port 22. After the coins are fed out to the deposit reject port 22, the control unit detects the open / close state of the open / close door 30 provided in the deposit reject port 22 by the reflective optical sensor 33, and the open / close door 30 is closed. If it is determined from the detection result of the reflection type optical sensor 33 that it is in the open state and closed again, it is determined that the coins in the deposit reject port 22 have been taken out, and the alarm lamp 23 is turned off. Here, the alarm lamp 23 is turned off when it is determined from the detection result of the reflective optical sensor 33 that the open / close door 30 has been opened from the closed state after the coins are fed to the deposit reject port 22. May be. Alternatively, the alarm lamp 23 is turned off when it is determined from the detection result of the reflective optical sensor 33 that the opening / closing door 30 has been changed from the open state to the closed state after the coins are fed to the deposit reject port 22. Also good.

  According to the coin handling machine 1 using the open / close door device 38 of the present embodiment described above, the retroreflective sheet 40 is provided on the surface of the closed open / close door 30 facing the reflective optical sensor 33. Therefore, if the open / close door 30 is swung by a slight angle from the closed state, the reflected light from the retroreflective sheet 40 is received by the reflective optical sensor 33 without shifting, and the open / close door 30 is reliably In the open state, the reflected light from the retroreflective sheet 40 shifts and is not received by the reflective optical sensor 33. Therefore, even when the reflective optical sensor 33 is used, it can be detected that the open / close door 30 is reliably opened from the closed state. As a result, it can be detected that the coin from the inside of the machine has been reliably taken out from the deposit reject port 22.
