Title:
SIGNAL OUTPUT DEVICE, SHEET MATERIAL TYPE DISTINGUISHING DEVICE, IMAGE FORMING DEVICE, AND SHEET MATERIAL TYPE DISTINGUISHING METHOD
Document Type and Number:
Japanese Patent JP3673777
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To distinguish the type of a sheet material even if information such as numerical code is not fixed to the sheet material beforehand.
SOLUTION: When a vibration application part 1000 applies vibration to the sheet material 1010, the vibration is attenuated in a process of being transmitted to the sheet material 1010, and the information is outputted as signals from a detection part 1020. Since the signals vary depending on the type of the sheet material 1010, the type of the sheet material can be distinguished based on the signals. By this method, even when the information such as numerical code is not fixed to the sheet material beforehand, the information on the type of the sheet material can be outputted.
