The arrangement space 22 extends in the left-right direction, and articles such as a plurality of display cards SC are covered with a transparent cover member 22a. The article such as the exhibition card SC is, for example, an article such as a card of the same series as the card C being sold, or an article such as a card of another series.

  In the case of the present embodiment, the arrangement space 22 is located below the display unit 21 and above the operation panel 3, and the display unit is provided even when a peripheral (peripheral device) having a height is mounted. There is an advantage that the visibility of 21 is not deteriorated. Specifically, the operation panel 3 may be equipped with a device imitating an item or the like appearing in a game story as a peripheral (not installed in the present embodiment), and the display unit 21 due to the presence of this peripheral. Visibility may deteriorate. In order to improve visibility, in this embodiment, the display unit 21 is arranged slightly apart from the operation panel 3 and arranged upward, and an empty space generated below the display unit 21 is effectively used as the arrangement space 22.

  Next, referring to FIG. 1 and FIG. 3, an article mounting portion 23 is provided in the upper part of the display / exhibition portion 2. In the case of the present embodiment, the bullet display card DC is illustrated as an article to be mounted on the mounting portion 23, but other articles may be used, and other than the card can be used as the bullet display article. It is. The bullet number display card DC is a display body for displaying the bullet number of the card C currently on sale. The mounting portion 23 has an insertion opening 23 b opened on the upper side surface of the display / exhibition portion 2 and is formed in a slot shape, and has an opening 23 a on the upper front of the display / exhibition portion 2. The entire upper front surface of the display / exhibit unit 2 is covered with a transparent panel 24, and the opening 23, which is the front surface of the mounting unit 23, is also covered with the transparent panel 24.

  Referring to FIGS. 1 and 5, the entire front surface below the operation panel 3 of the article sales apparatus A has an input unit 11 for inputting a purchase price as a consideration for the card C and a payout unit 12 for paying out the card C. The display / exhibit section 2 is covered with a transparent panel in the same manner as the entire upper front surface except for the portion corresponding to the By sandwiching the decorative sheet with the transparent panel, information on the character, game content, and the like can be provided by the decorative sheet. In addition, since the input part and the payout part are provided below the operation panel, the user always sees the lower part from the operation panel. Sheets were never provided.

  The insertion port 23b is closed by a panel-like closing member 25 that is detachably attached by screwing the screw 25a into the screw hole 25b. The bullet number display card DC is introduced by being inserted into the insertion slot 23b with the closing member 25 removed, and the surface thereof is exposed from the opening 23 and visible to the customer through the transparent panel 24. When the closing member 25 is attached, the bullet number display card DC is in a sealed state, so that theft or the like can be prevented. In addition, the structure which inserts in the insertion port 23b in the state which attached the card | curd number display card DC to the panel-shaped closing member 25 may be sufficient.

Next, the structure of the operation panel 3 will be described with reference to FIGS. As shown in FIG. 5, the operation panel 3 includes a hollow main body 30 that constitutes the outer wall of the operation panel 3, and a plurality of openings 30 a to 30 d are provided on the upper surface of the main body 30. The inside of the main body 30 can be accessed via 30a to 30d. The inside of the main body 30 is used as, for example, a space for wiring installation connected to the back surfaces of a plurality of panels or a space of a portion of the operation member that protrudes from the bottom surface of the panel.
Further, the portion protruding from the lower surface of the panel can easily position the panel when closing the openings 30a, 30a (the panel can be positioned simply by fitting the protruding portion to the opening. ). This is because the mounting position of the operation member on the panel is set so that the portion protruding from the lower surface of the panel is always located at the opening when the operation panel is mounted.

  A pair of openings 30a are formed on the front side of the upper surface of the main body 30 so as to be separated from each other on the left and right, and the opening 30b is formed at a position between the openings 30a and 30a. A pair of openings 30c are formed on the back side of the upper surface of the main body 30 so as to be separated from each other on the left and right, and the opening 30d is formed at a position between the openings 30c and 30c.

  The operation panel 3 includes a plurality of panels 34 to 36 that close the openings 30a to 30d. The single panel 34 covers the entire upper front side (front side) of the main body 30 and closes the openings 30a, 30a, and 30b. The panel 34 is formed in a substantially U-shape, and operation units 31R and 31L (switches 31a (operation members)) are attached to both ends to constitute an operation unit. 3 is formed with a notch for exposing the upper portion of the placement portion 32 on which an article such as a card is placed. In the present embodiment, a decorative sheet 34 a and a transparent panel 34 b are sequentially laminated on the panel 34, and a plurality of screws 34 c that penetrate the laminated body are screwed into screw holes 30 ′ provided on the upper surface of the main body 30. By doing so, it is detachably attached to the main body 30.

  By providing the transparent panel 34b, it is possible to protect the panel 34 that is easily soiled by the player's operation. The decorative sheet 34a and the transparent panel 34b have the same outer shape as the panel 34, and are provided with opening portions 34a 'and 34b' that expose the operation portions 31R and 31L (switches 31a (operation members)), respectively. Since the decorative sheet 34a is simply sandwiched between the panel 34 and the transparent panel 34b, the replacement is easy. For this reason, for example, the decorative sheet 34a having a different design depending on the new model can be easily attached.

  The pair of panels 35 and 35 closes the openings 30c and 30c, respectively. The panel 35 has two locking portions 35a on both the left and right side portions (only the two locking portions 35a on the right side are visible in FIG. 5). The four locking portions 35a of each panel 35 have the same shape, and the two locking portions 35a located on the outer side in the left-right direction are inserted into the slits 30e, 30e provided in the main body 30 and positioned on the inner side in the left-right direction. The two locking portions 35a to be inserted are inserted into holes 30f and 30f provided in the main body portion 30.

  The slit 30e opens laterally toward the side edge of the main body 30. When the locking portion 35a is inserted, the panel 35 moves upward due to interference between the upper wall of the slit 30e and the locking portion 35a. Is regulated. Although only the locking portion 35a is inserted into the hole 30f, the upper surface of the locking portion 35a inserted into the hole 30f is the main body when the panel 35 is placed at the specified position on the main body portion 30. It is substantially flush with the upper surface of the portion 30. And when the panel 36 is attached on the main-body part 30, the peripheral part of the panel 36 will overlap with the latching | locking part 35a inserted in the hole 30f. Due to the interference between the locking portion 35a inserted into the hole 30f and the lower surface of the panel 36, the upward movement of the panel 35 is completely restricted and cannot be removed.

  Thus, in this embodiment, the attachment / detachment mechanism of the panel 35 is not configured to be attachable / detachable with screws or the like, but is configured to use attachment of another panel 36. This helps to reduce the man-hours for attaching and removing screws.

  The panel 35 has a recess 35b. The concave portion 35b can be used as a card case or an accessory case. The recess 35b can also be used as an IC card placement section. In this configuration, an IC card writing / reading device is provided on the back side of the panel 36. The IC card is sold separately from the card C sold by the article sales apparatus A (for example, sold at a store). Then, information such as the result of the game played by the player in the article sales apparatus A is written, read out, and used for the game.

  The depth of the recess 35b is deeper in the depth direction (front side → back) of the article sales apparatus A. For this reason, for example, an article such as a card placed in the recess 35b is likely to be stored in a fixed position on the back side, and even if the player operates the operation unit and the article selling apparatus A vibrates, it is difficult to drop off. . For example, as described above, when the concave portion 35b is used as an IC card placement portion, the position of the IC card and the writing / reading device tends to be in a fixed relationship, and errors in writing and reading are prevented. Can be suppressed.

  On the front side (front side) in the depth direction of the article sales apparatus A, a recess 35 c is provided on the bottom surface of the recess 35. This facilitates the removal by inserting the fingertip into the recess 35c when the player takes out an article such as a card placed in the recess 35.

  The panel 36 closes the opening 30d. The panel 36 is detachably attached to the main body 30 by screwing a plurality of screws 36 a into screw holes 30 ′ provided on the upper surface of the main body 30. In the present embodiment, the opening 30d is closed by a simple panel 36, but may be closed by a panel provided with a peripheral. Since the opening 30d is located on the back side of the center of the upper surface of the operation panel 30, it is optimal as a peripheral portion.

  In the vicinity of the opening 30d, a connector portion 37 for wiring connection is provided inside the main body 30. As shown in FIG. 6B, the peripheral portion of the opening 30d covers the upper portion of the connector portion 37, and the connector portion 37 is located at a position slightly behind the opening 30d. While securing the connection workability of the wiring to the connector, it is possible to avoid an impact from the upper part due to an attachment error of the panel 36 and the like, and to protect the connector portion 37.

  As described above, in the present embodiment, a plurality of openings 30 a to 30 d are provided on the upper surface of the main body 30 of the operation panel 3, and these are closed by the operation unit including the panels 34 to 36. With this configuration, when the configuration (operation units 31R, 31L, peripherals, etc.) located on the upper surface of the operation panel 30 is changed or replaced, design and work can be performed in units of the panels 34 to 36. Therefore, when a new article sales apparatus A is newly designed for each character or game content, a new article sales apparatus A can be designed and manufactured by changing the panels 34 to 36 while using the main body 30 in common. A device configuration corresponding to the character, game content, etc. can be realized at a lower cost. Further, for example, when a failure occurs in a part of the operation units 31R and 31L, the unit can be replaced (detached) together with the panel 34 (every time), so that the replacement work is facilitated and the maintainability can be improved. Since the replacement work is a work from above the operation panel 3 including the wiring work, the work posture of the worker is not obsolete and the work efficiency can be improved.

  With reference to FIGS. 1, 4, and 5, in the case of the present embodiment, protruding portions 302 are formed on the left and right side surfaces of operation panel 3 so as to protrude left and right with respect to the side surface of article sales apparatus A. Further, the left and right side surfaces of the display / exhibition unit 2 are also formed with protruding portions 303 that protrude left and right from the side surface of the article sales apparatus A. As a result, even when a plurality of article sales apparatuses A are installed side by side, the side surfaces of the article sales apparatus A are not in direct contact with each other, and only the protrusions 302 and 302 and the protrusions 303 and 303 are in contact with each other. Therefore, the heat generated from the article sales apparatus A can be dissipated more efficiently, and damage to the side surface of the article sales apparatus A can be reduced, so that this protruding portion also functions as a protective member. In addition, since the article sales apparatus A is supported (contacted) by two places, the protrusion part 302 provided in the horizontal direction, and the protrusion part 303 provided in the vertical direction, a player operates an operation part. Thus, even when a pressing force is applied to the article sales apparatus A itself, the movement of the article sales apparatus A itself can be reduced as compared with the case where the protrusions 302 and 302 are supported alone.

  Next, a configuration around the placement unit 32 will be described. As shown in FIG. 4, the placement unit 32 has both left and right ends at the center in the left and right direction at the front end of the operation panel 3 (both sides at the center in the left and right direction at the front end of the operation panel 3). 301 and the protrusion part 32b which protruded ahead (this side) rather than 301 is provided. The left and right end portions 301, 301 are curved surfaces (curved surfaces that are part of a semicircle in the cross section) protruding forward (front side) in the vertical direction. Since the player's standing position when playing the game is in front of the operation portions 31R and 31L of the operation panel 3, the left and right end portions 301 and 301 where the player's arms and trunks may come into contact are curved. The risk of injury can be reduced by forming. Moreover, if the insertion part 11 for inputting the purchase price which is the price of the card C and the payout part 12 for paying out the card C are formed on the left and right parts 301, 301 (surfaces thereof) on an arcuate curved surface as described above. Since it is difficult to exert the effect, it is desirable not to form it.

  The placement surface 32a extends from the protruding portion 32b to the vicinity of the operation units 31R and 31L in the depth direction of the article sales apparatus A. In this way, the configuration in which the protruding portion 32b is provided and the placement surface 32a extends to the front side (front side) of the article sales apparatus A makes it easy for the player to easily read the card C, and the two players battle each other. When playing a game, it is useful also as a structure which partitions a standing position. On the other hand, since the article sales apparatus A is often installed in a busy passage or in a store, a passerby may hit the protruding portion 32b and damage the vicinity of the protruding portion 32b.

  In this embodiment, the outer shape of the protruding portion 32b is widened from the front side (near side) to the back side of the article sales apparatus A in a plan view, and the apex portion 32b ′ forms an arcuate mountain shape, and the side surface is curved. There is no. For this reason, even if a passerby hits the projecting portion 32b, the projecting portion 32b slides in the direction of the arrow d, so that the impact on the periphery of the projecting portion 32b is alleviated and damage to the mounting portion 32 can be reduced.

  With reference to FIG. 5 and FIG. 6A, in the case of this embodiment, the mounting surface 32a is formed by a transparent panel 323. The transparent panel 323 is detachably mounted on an outer wall constituting member 321 constituting the outer wall of the placement portion 32. In the case of this embodiment, the outer wall constituting member 321 is a part of the main body 30, and the transparent panel 323 is detachably attached to the upper surface of the outer wall constituting member 321 by screwing the screw 323 'into the screw hole 30'. Is done. Since the transparent panel 323 is detachably provided and the upper surface thereof is the mounting surface 32a, it is possible to facilitate cleaning of the mounting surface 32a that is easily contaminated. In addition, since the transparent panel 323 is configured to be detachable, for example, a card or other article placement surface such as “Click here to read an article such as a card” is provided between the transparent panel 323 and the placement unit 32. It is also possible to sandwich a decorative sheet on which a display indicating the presence or the like is made.

  Guide portions 324 and 324 are integrally provided on the outer wall constituting member 321. The guide portions 324 and 324 are spaced apart from each other in the left-right direction, and the inner side surface is inclined so that the distance between the guide portions 324 and 324 is wider than the width of the card C on the front side and substantially equal to the width of the card C on the back side. doing. The reading unit 33 arranged on the back side of the placement surface 32 and the guide units 324 and 324 have a predetermined arrangement relationship, and the player slides the card C on the placement surface 32 to the back side. Only by this, it can be reliably guided to the reading position of the reading unit 33 arranged on the back side of the mounting surface 32.

  An opening (notch) 321a is formed on the back side of the outer wall constituting member 321, and the reading unit 33 faces the opening 321a so as to read the lower surface of the card C placed on the placement surface 32a. It is arranged.

  In general, an image of a character or the like appearing in a game is printed on the front surface of the card C, and game data is recorded (printed) in the form of a barcode or the like on the back surface. Conventionally, since the placement surface of an article such as a card has not been formed by a transparent panel, the reading unit is provided above the placement surface of the article such as a card. For this reason, game data is printed ( The recorded surface (back surface) was placed on the placement surface of an article such as a card so that the surface on which an image of a character or the like was printed is downward. I could not grasp at a glance whether the data of the article was read. Therefore, when the reading unit 33 is configured to read the lower surface of the card C, the upper surface of the card C on the placement surface 32a becomes a display surface for images of characters and the like, and the type of the card C currently used by the player is selected. There is an advantage that it is easy to recognize.

  Providing the opening 321a may cause the card C to drop downward from the opening 321a. However, in this embodiment, the transparent panel 323 has an extending portion 323a extending on the opening 321a. Thus, the opening 321a is closed. For this reason, the card | curd C does not fall below from the opening part 321a.
