Description

  The present invention relates to a disc body identification device mounted in a machine body such as a pachinko machine, a lending machine such as a medal, a vending machine, a ticket vending machine, a change machine, etc. The present invention relates to a disc body identification device that identifies a disc body, and more particularly to a disc body identification device that cleans a rail on which the disc body rolls and travels.

  In the disc body identification device for discriminating disc bodies such as coins, medals, tokens, etc., the inserted disc body rolls along the rail of the disc body guide passage and travels between the disc bodies. The authenticity of the disc body, the type of disc body, or the like is discriminated through disc body identification means arranged on the side of the guide passage.

  This disc body identifying means is for authenticating / identifying from the diameter / thickness / material, etc. of the disc body by means of a magnetic sensor, an optical sensor, an image sensor or the like.

  On the other hand, dirt such as dust, dust, and foreign matter is likely to adhere to the disc body running surface of the rail that guides the travel of the disc body described above, and such dirt, dust, foreign matter, etc. adhere to the rail. As a result, the disc body is obstructed and smooth disc identification processing is not possible, and the discriminating accuracy is also adversely affected. There is also a risk that the disc body cannot be identified. Therefore, in the past, regular rail cleaning work by an operator has been required.

In addition, there exists Unexamined-Japanese-Patent No. 2003-190619 for which the applicant of this application applied previously as a rail cleaning apparatus mentioned above.

  By the way, according to the above-described conventional disc body identification device, removal of dirt such as dust adhering to the rail body running surface of the rail depends on periodic cleaning work by the operator, so that the dirt can be quickly removed. In the meantime, there is a possibility that the disc body identification device cannot be used, and an immediate countermeasure has been desired.

  That is, in the disc body identification device mounted on the vending machine, the front door of the vending machine is opened and closed one by one to expose the disc body identification device, and then the operator must perform the cleaning work. There is a risk that customers will be missed because sales are temporarily suspended to open the door of the vending machine.

  An object of this invention is to provide the disc body identification device which can remove easily dirt, dust, a foreign material, etc. adhering on a rail in view of the situation mentioned above.

  In order to solve the above-described problem, in the present invention, in the disc body identification device configured to run the inserted disc body on the rail provided along the disc body guide passage, the rail is always operated. In addition to retracting from the disk body running surface, a rail cleaning means that can protrude and retract toward the disk body running surface of the rail when the rail is cleaned is disposed.

  According to the rail cleaning means described above, the rail is always retracted from the rail traveling surface of the rail and allowed to travel, and the rail is projected toward the disc traveling surface during the cleaning of the rail. Since the rail cleaning means consisting of a cleaning unit that removes dirt such as dust, dirt and foreign matter attached to the rail is disposed, dirt such as dust, dust and foreign matter attached on the rail is It can be easily removed from the disc body running surface by simply projecting the cleaning part toward the running surface, so that the disc body can be smoothly run on the rail and the disc body can be identified stably for a long time. It is possible to provide a disc body identification device that performs the above.

  Further, even if the vending machine is not opened and closed, the gate lever is operated in conjunction with the operation of the return lever of a known vending machine (not shown) so that the vending machine can be cleaned.

Furthermore, since the vending machine is not opened during cleaning, the problem of missing sales opportunities can be avoided by temporarily suspending sales.

  In addition, since the dust is removed when the customer returns the coin when canceling the purchase, the dust can be removed without performing any cleaning work.

  If the return lever is operated when coins are jammed, the coins are returned, and the dust causing clogging can be removed.

  Hereinafter, an embodiment of the disc body identification device according to the present invention will be described in detail.

  FIG. 1 is a partially broken sectional view of a disc body identification device 1 according to the present invention.

In the disc body identification device 1, a main plate 3 constituting the device main body 2 and a gate plate 4 are disposed at positions facing the main plate 3, and between the main plate 3 and the gate plate 4. Are formed with first and second disk body guide passages 7 and 8 for guiding the disk body 6 such as coins, medals and tokens inserted into the disk body insertion slot 5.
Among these, the disc body 6 rolls in the right direction in the drawing in the second disc body guide passage 8 that guides the disc body 6 that has passed through the first disc body guide passage 7 in the right direction in the drawing. An inclined rail 10 for running is provided, and an identification means 11 is provided in the main plate 3 located on the side thereof. The identification means 11 is authentic / identified from the diameter / thickness / material, etc. of the disc body by means such as a magnetic sensor, optical sensor, image sensor, etc. as in the prior art.

   The rail 10 is formed so as to protrude from the side of the gate plate 4 toward the main plate 3 side of the gate plate 4 as shown in FIG.

The rail 10 is a bottom surface of a passage for rolling the disc body 6, and a rail constituted simply by a flat surface is also referred to here.

   On the other hand, as shown in FIGS. 1 and 2, the gate plate 4 located on the side of the rail 10, i.e., below the identification means 11, is contaminated with dust, dirt, foreign matter, etc. adhering to the rail 10. Rail cleaning means 20 for eliminating D is provided.

   The rail cleaning means 20 is arranged along the longitudinal direction of the rail 10 so as to sandwich the upper and lower surfaces 10a, 10b of the rail 10 as shown in FIG. By a pair of coil springs 21 that are arranged biasing means, a substantially U-shaped cross section that is constantly biased so as to protrude from the pair of upper and lower slits 4a, 4b formed in the gate plate 4 to the main plate 3 side. Projecting portion 22.

   Of the projecting portion 22 having a substantially U-shaped cross section, a portion that can be projected and retracted from one slit 4 a toward the upper surface (disk body running surface) 10 a of the rail 10 is a cleaning portion 23.

   The cleaning portion 23 is formed in a substantially triangular cross section so that its tip 23a is in sliding contact with the upper surface 10a of the rail 10, and the entire length of the cleaning portion 23 is along the longitudinal direction of the rail 10, as shown in FIG. It is set to a length that covers almost the entire area.

   On the other hand, in the protruding portion 22 having a substantially U-shaped cross section shown in FIG. 3, a portion protruding from the other slit 4 b toward the lower surface 10 b of the rail 10 causes the cleaning portion 23 to be gated from the upper surface 10 a of the rail 10. It functions as a pressing portion 24 for retracting to the back side of the plate 4.

  That is, when the gate plate 4 rotates about the shaft 51 by the urging force of the return spring 50 of the gate plate 4 shown in FIG. 1 and approaches the main plate 3 as shown in FIG. And the gate plate 4 further approaches the main plate 3 by the urging force of the return spring 50 shown in FIG. 1, the pressing portion 24 is moved by the pressing force as shown in FIG. 3. As shown by an arrow C against the urging force of the coil spring 21, the coil spring 21 moves backward.
