PURPOSE:To simplify the maintenance from the standpoint of a user, to increase synthetic strength by the fixing of an inner case, to enhance reliability and to reduce cost, by integrally forming a display unit and a keyboard to a door. CONSTITUTION:A display unit 24, an operation switch 25 and a setting keyboard 26 are integrally mounted to a door 20. The setting of the switch 25 and the keyboard 26 is performed on the front surface of the door 20 in such a state that the door 20 is closed. The display of the unit 24 can be directly looked from the front surface of the door 20 and the data recorded on a chart can be seen through a transparent glass part 21. As the maintenance works to be performed by a user, there are the replacement work of a ribbon cassette 31 for a wire dot printer and that of a backup battery but works can be performed without swinging an inner case 30. Since the inner case 30 is fixed to a case 10, the total strength of this meter is enhanced. Further, since zero span adjustment can be directly performed from the front surface of the door, workability is enhanced.
