Title:
DEVICE FOR IDENTIFYING COIN-SHAPED OBJECT TO BE DETECTED
Document Type and Number:
WIPO Patent Application WO/2014/080880
Kind Code:
A1
Abstract:
Provided is a device for identifying a coin-shaped object to be detected, the device enabling the suppression of a decrease over time in the identification accuracy of the coin-shaped object to be detected, and enabling the simplification of a configuration.
This device for identifying a coin-shaped object to be detected is provided with a first core (12) and a second core (13) that are disposed with a predetermined space therebetween in the thickness direction of the coin-shaped object to be detected, in the first core (12), protruding portions (12a-12c) which protrude to the second core (13) side and around which an excitation coil (8) is wound are formed, and in the second core (13), protruding portions (13a-13c) which protrude to the first core (12) side and around which detection coils (9, 10) are wound are formed. A passage path (5) through which the object to be detected passes is formed between the protruding portions (12a-12c) and the protruding portions (13a-13c) in the thickness direction of the object to be detected. The distance between the end surface in the X1 direction of the protruding portion (12a) and the end surface in the X2 direction of the protruding portion (12b), and the distance between the end surface in the X1 direction of the protruding portion (13a) and the end surface in the X2 direction of the protruding portion (13b) are larger than or equal to the outer diameter of the object to be detected.
