  When the air purifier 11 configured in this way is installed in the intermediary machine 3, as shown in FIG. 4, between the partition wall 3 a and the pocket portion 20 that partitions the intermediary machine 3 and the pachinko machine 2. A gap 31 having an interval H is formed.

  Next, the shutter unit 40 will be described with reference to FIGS. 2 and 6 to 9. As shown in FIG. 2, the shutter unit 40 is supported between a rectangular tube-shaped discharge duct 41 having both ends in the direction of arrows A-B opened, and a ceiling portion and a bottom portion of the discharge duct 41. A shutter 43 rotatably supported on the shaft 42, ribs 44a and 44b as stoppers for positioning the shutter 43 at a predetermined closing position, and a rotary solenoid 45 for rotating the shutter 43 are provided.

  As shown in FIG. 2, the discharge duct 41 is detachably fitted to the discharge ports 27a and 28a side ends (arrow B direction side ends) 46 of the ducts 27 and 28, as shown in FIG. A collar 41a is provided. The cross-sectional area of the flange 41a is slightly larger than the cross-sectional area of the discharge duct 41. A discharge port 41b through which the air W2 is discharged is provided at the end of the discharge duct 41 in the arrow B direction.

  As shown in FIG. 8, the shutter 43 protrudes in opposite directions from a cylindrical pivot 43 a that is rotatably supported by the shaft 42, and from a portion 180 degrees apart in the circumferential direction of the peripheral portion of the pivot 43 a. And a pair of rectangular blades 43b and 43c. As shown in FIG. 9, the ribs 44 a and 44 b are projected on the inner peripheral surface excluding the pivot 43 a of the discharge duct 41 so as to be entirely U-shaped. Accordingly, when the rotary solenoid 45 is turned on and the shutter 43 is rotated as will be described later, the entire peripheral portions of the blades 43b and 43c of the shutter 43 abut against the ribs 44a and 44b as shown in FIG.

  The rotary solenoid 45 is attached to the bottom of the discharge duct 41, the pivot 43a of the shutter 43 is fixed to the output shaft 45a, and the pivot 43a rotates integrally with the output shaft 45a. When the rotary solenoid 45 is turned on, the output shaft 45a rotates 90 ° counterclockwise as shown in FIG. 8A, so that the blades 43b and 43c of the shutter 43 abut against the ribs 44a and 44b, and each duct. The outlets 27a and 28a of 27 and 28 are closed.

  On the other hand, when the rotary solenoid 45 is turned OFF, the output shaft 45a rotates 90 ° clockwise as shown in FIG. 9 by the urging force of a return spring (not shown) built in the rotary solenoid 45. The discharge ports 27a and 28a of the ducts 27 and 28 are opened. In the shutter unit 40 configured in this way, by fitting the flange portion 41a to the end portion 46 on the discharge port 27a, 28a side, the discharge port 41b of the discharge duct 41 becomes the discharge port 27a of each duct 27, 28. The air purifier 11 is attached to the air purifier 28a.

  Next, the operation | movement which cleans air with the air purifying apparatus 11 comprised in this way is demonstrated using FIGS. First, an operation for discharging the cleaned air W2 from the discharge port 41b of the shutter unit 40 will be described. In this case, the rotary solenoid 45 is turned OFF, and the outlets 27a and 28a of the ducts 27 and 28 are opened as shown in FIG.

  When the blower 13 is operated in this state, the air in the intermediary machine 3 in FIG. 4 passes through the filter 22 from the suction hole 20a of the pocket portion 20, and enters the blower 13 from the suction port 13a as shown in FIG. Inhaled, air W1 is discharged into the ion ducts 27 and 28 from the discharge port 13b.

  The air W1 from which the ions 33 and 34 have been released is decomposed into odorous components such as dust and cigarettes by the ions 33 and 34, so that the air W1 is cleaned as the air W2, and the outlets 27a and 28a of the air purifier 11 are cleaned. Through the outlet 41b of the shutter unit 40, and is blown out from the outlets 5a and 5b of the interstage machine 3. Thus, since the air W2 blown out from the outlets 5a and 5b of the inter-machine 3 functions as an air curtain that partitions the air environment of the pachinko machine 2 at the boundary, cigarette smoke flows to adjacent players. Can be regulated.

  On the other hand, as shown in FIG. 5, a part of the air W2 is in contact with the reversing portions 27d and 28d and flows into the second duct 30 through the branch holes 27c and 28c. The air W3 flowing into the second duct 30 is guided in the second duct 30 in the direction of the arrow A, and as shown in FIG. It is discharged into the gap 31 between the two.

  The air W3 released into the gap 31 passes through the filter 22 from the suction hole 20a of the pocket portion 20 together with the air in the inter-machine unit 3, and is sucked into the blower 13 from the suction port 13a. It is refluxed into the blower 13. Thus, the device itself can have a self-cleaning action, and the replacement period of the filter 22 can be extended. In addition, when the air W3 is recirculated into the blower 13, the ions 33 and 34 decompose the odorous components such as dust and cigarette attached to the blower 13 that are difficult to clean, thereby allowing long-term use. The adverse effect of odor can be reduced.

  Here, when the self-cleaning action of the device itself is more necessary, the rotary solenoid 45 is turned ON when the game shop is closed, and the outlets 27a and 28a of the ducts 27 and 28 are provided as shown in FIG. The shutter 3 is closed by the blades 43b, 43c. Accordingly, the air W2 discharged from the discharge port 13b of the blower 13 and releasing the ions 33 and 34 in the ion ducts 27 and 28 is externally discharged from the discharge port 41b by the shutter 43 as shown in FIG. Without being discharged, all the air W2 flows into the second duct 30 through the branch holes 27c and 28c as the air W3.

  For this reason, since the amount of the recirculated air W3 increases, the force for decomposing odor components such as dust and cigarettes adhering to the blower 13 increases, so that the replacement period of the filter 22 can be extended more reliably. At the same time, the adverse effects of odor due to long-term use can be reduced more reliably.

  Further, since the blades 43b and 43c of the shutter 3 with the discharge ports 27a and 28a closed are all in contact with the ribs 44a and 44b as shown in FIG. 8, the inside of the discharge duct 41 is formed by the ribs 44a and 44b. Since it is in a sealed state, the air W2 does not leak out of the apparatus from the discharge port 41b. For this reason, since all of the air W2 can be reliably guided into the second duct 30 and recirculated to the blower 13 via the filter 22, the self-cleaning action of the device itself is further improved.

  In this embodiment, when the self-cleaning action of the device itself is more necessary, it is performed at the time when the business of the amusement store is completed, but it may be performed before the business is started, by button operation, It may be turned on and off, or automatically turned off by a timer, and various design changes are possible. In addition, the shutter unit 40 is directly attached to the outlets 27a and 28a side end portions 46 of the ducts 27 and 28, but the air purifier 11 is exhausted via a bracket (not shown) attached to the inter-vehicle machine 3. You may make it arrange | position in the exit 27a, 28a side edge part 46. FIG.
