An inspection system is configured to inspect a valuable object including an RF tag configured to record information. The inspection system includes an RF reading device, a weight measuring device, a management control device, and a display device. The RF reading device is configured to read information of valuable objects from RF tags of the valuable objects placed. The weight measuring device is configured to measure weights of the valuable objects. The management control device is configured to determine a calculated total weight of the valuable objects on the platform based on standard weights of the valuable objects obtained from the information read by the RF reading device and compare the calculated total weight with an actual total weight of the valuable objects measured by the weight measuring device. The display device is configured to perform a display reflecting a result of a comparison by the management control device.

When an unfair gaming currency is delivered to a dealer from a player, the currency is detected as unfair. The inspection system for inspecting the gaming currency, in which an RF tag is built, comprises: a gaming currency tray for housing the gaming currencies of the dealer in a casino game; an RF reader for reading the RF tags of the plural gaming currencies housed in the gaming currency tray; plural photosensors for detecting at least the number of the plural gaming currencies housed in the gaming currency tray at a constant time interval or always in a method other than RFID; and an inspection/alarm part for generating alarms when the number of the gaming currencies whose RF tags are read by the RF reader is not equal to the number of the gaming currencies detected by the plural photosensors.

Since a game token (chip) on a game table has a complicated design, it is difficult for an image analysis technology to judge whether a dealer correctly redeems chips corresponding to betted chips at the time of redemption and there has been a problem that mistake prevention is not sufficient.

A table game management system according to the present invention includes: a camera (4) that images a game token (100) placed on a game table (1); and a management control device (9) that grasps a type (10 points, 20 points, 100 points, 1,000 points, or the like) of the game token (100) placed on the game table (1) based on a color of a side face of the game token (100) imaged by the camera (4).

A flexible installation for producing at least two types of coins. In particular, the different coin types have a different number of round blank parts and/or have round blank parts made of different materials. The type and number of work steps necessary to produce the coins of the coin type in question differ between the different coin types. The installation has a number of stations, in which a round blank part is supplied and/or output and/or processed and/or measured and/or tested. At least one transporting device acts to transport the at least one round blank part between the stations. Preferably, two transporting devices are present, which can be controlled independently of each other and cooperate via a transfer station for the at least one round blank part. A control device controls the at least one transporting device and the stations depending on the coin type to be produced.
