INSTALLATION/REMOVAL DEVICE, DISPLAY CHANGE DEVICE, AND DOSING SYSTEM

摘要

It is an object of the invention to provide an installation/removal device capable of favorably installing and removing a card fitted to a conveyed object; a display change device including the installation/removal device; and a dosing system including the installation/removal device. A display change device 10 is formed by connecting and thereby integrating an installation/removal device 2 and a card display change device 3 together. The card installation/removal device 1 is configured to have at a back side thereof a pressure receiving wall 23e, at a further back side of which a position adjustment mechanism part 100 is provided. The position adjustment mechanism part 100 is configured to include a seat member 101, a moving part 102, and a drive part 103. The position adjustment mechanism part 100 is configured to strike and move the card installation/removal device 1 by an eccentric cam 112. The position adjustment mechanism part 100 moves the eccentric cam 112 far from the pressure receiving wall 23e under the condition that a reaction force Fr received by the eccentric cam 112 becomes larger than a force Fa for pulling the moving part 102 toward the pressure receiving wall 23e side.
