Claims

[Scope of utility model registration request]

A door is pivotally attached to the front surface of the casing so as to be openable and closable, and one end is pivoted at a position that is offset by a predetermined distance from a pivot point of the door and urges the door to rotate in the opening direction, Further, a lever unit whose other end extends inside the housing so as to be movable in the door opening/closing direction, and a first spring tensioned so as to bias the lever unit in the door opening/closing direction. , a tamper means that is connected to the lever unit via a connecting member and that applies a resistance force to at least the movement when the lever unit is urged by the first spring and moves in the lid opening direction; A door opening/closing device comprising: a second spring attached to the lever so as to gradually balance the spring pressure of the first spring as the door is opened. ′
