摘要： PROBLEM TO BE SOLVED: To prevent print quality from lowering without prolonging a print time by preventing power supply input from being switching between a battery and an AC power supply in the way of print operation. SOLUTION: A cut 33 is provided in a contact part 32 of an AC adapter. A cam 45 takes a state A at the time other than printing and a state B at the time of printing. When printing is started under a state where the contact part 32 is inserted into a connector, a stopping part 42 is fitted in the cur 33 by means for the cam 45 thus locking the contact part 32. When printing is stared under a state where the contact part 32 is not inserted into the connector, the stopping part 42 blocks insertion of the contact part 32. After starting point operation, insertion/removal of the contact part 32 of the AC adapter is prohibited and the power supply voltage is held at a constant level.

摘要： PROBLEM TO BE SOLVED: To provide an ink jet printer having a print head capable of being readily fixed when the printer is moved so that the print head is prevented from being broken. SOLUTION: This ink jet printer comprises a drum 3 for conveying a paper in a predetermined direction by bringing the paper into contact with the outer periphery 3a of the drum 3 to be held, a nozzle unit 5 that prints an image by ejecting ink to the paper which is provided to be vertically displaced between a printing position close to the outer periphery 3a of the drum 3 and a fixing position upwardly separated therefrom, an elevating mechanism 20 for elevating and lowering the nozzle unit 5 and a holding mechanism 40 that holds the nozzle unit 5 elevated to the fixing position by the elevating mechanism 20 in a condition free from the elevating mechanism 20. The holding mechanism 40 holds a holding pin 54 provided on a top end of the nozzle unit 5 which is thus held in suspended state.

摘要： PROBLEM TO BE SOLVED: To facilitate maintenance by providing an information input means for attaining the right of using, means for comparing input information with information held in an information holding means, and means for controlling the availability of an apparatus depending on the comparison results thereby making possible to limit the user. SOLUTION: When power is turned on, initialization is performed and an input request screen of ID and pass word is presented on the display section at an operating section 115. Inputted ID and password are checked against a data stored in a management data storing section 120. Since cipher data and a clear data are stored in the management data storing section 120, comparison is made at first with the clear data and if a matching data is not found, the inputted ID and password are encrypted and compared with the cipher data in the management data storing section 120. The cipher data in the management data storing section 120 is subjected to nonreversible processing.
