PURPOSE:To enable businessat data processing at oil feeding field and to improve working efficiency by providing a case with a door open/close detection switch to set off in the state where the door is entirely opened and to set on in the state where the door is entirely closed after the entirely-opening of the door. CONSTITUTION:In this data input/output device 3, a printer 8 is arranged in a case 3a. The bottom of a open/close door 18 is fixed to one terminal of a nearly-U-shaped lever 16 of which the other terminal is freely rotatably fitted to the case 3a with a pin and the open/close door 18 is freely rotatably fitted to the case 3a by the lever 16. Furthermore, the door open/close detection switch 20 is provided for the case 3a by positioning under the lever 16 and the contact point 20a of the door open/close detection switch 20 is projected upward. Consequently, only by slightly opening the open/close door 18 to degree of half-opening to correct the rolling-in or the folding of slip paper for a customer, the door opening/closing detection switch 20 is not set to be off but kept in the state of on. Consequently, the state is handled as the same state with that where the door is entirely closed and the printer is kept to be used. |
