PROBLEM TO BE SOLVED: To provide an operation panel for an elevator that can detect a button that hardly makes a response in a gradual manner due to aged deterioration.SOLUTION: An elevator 1 comprises: at least one operation button B; an operation section 41; a storage section 42: and a display section 43. The operation button B has electrical contact points B1 and B2 and outputs a signal by mechanical operation. The operation section 41 performs an operation of a value of resistance on the basis of a current flowing through the contact points B1 and B2 and a voltage applied to the contact points B1 and B2 when the signal is output, Then, the operation section 41 outputs the value of resistance subjected to the operation. The storage section 42 associates the value of resistance with time of day for each operation button B and records the value of resistance associated therewith. The display section 43 displays button information related to the value of resistance for each operation button B recorded in the storage section 42. |
