Abstract: An HMD includes a right light guide and a left light guide as a display section that displays an image with the display section mounted on a user's head in such a way that the user is allowed to visually recognize a real object. The HMD further includes a right sensor section and a left sensor section that detect approach of an instruction body to the right light guide and the left light guide and touchpads that accept operation. A control section of the HMD relates contents displayed in the right light guide and the left light guide to operation corresponding to motion of the instruction body detected by the right sensor section and the left sensor section in response to the motion of the instruction body.

Abstract: A transmission type head mounted display device is provided. The head mounted display device includes an image display unit that displays an image to allow a user wearing the head mounted display device to visually recognize the image and is capable of transmitting external scenery, a use environment determination unit (step S110, step S120) that determines a use environment of the head mounted display device, and a processing control unit (step S160, step S170) that changes at least a portion of a predetermined function built into the head mounted display device in accordance with the determined use environment.

Abstract: A printing method is provided for printing on a medium with a color material by a printer including a cartridge accommodating section that removably accommodates a cartridge to which an advance payment information storage section for storing therein advance payment information is attached and which contains the color material.

Abstract: There is provided a printer that performs print on a medium by color materials, including: an advance information reading and writing section that reads and writes advance information from and in an advance information holder for storing the advance information; a print control section that outputs a print driving controlling print when the advance information is read by the advance information reading and writing section; and a used amount acquiring section that acquires a used amount for the printer based on the print driving signal output from print control section.

Abstract: Facsimile systems, devices, and methods are provided related to transmitting an image from a sending device to a receiving device via a network. One embodiment includes a status information reply unit which replies to a notification request of status information from a sending device by transmitting status information representing status of the receiving-device to the sending device via a network, in which the status information reply unit includes a transmission source classifying portion which determines a class of the sending device and a selected-status information transmitting portion which transmits the status information to the sending device via the network.

Abstract: A printer generates a public key with a passphrase containing at least printer position information and a random number by a public key cryptography, and holds this random number. A print client previously acquires the public key from the printer. When transmitting print data to the printer, the print client encrypts the print data in advance with the acquired public key and transmits the encrypted print data as print transmitting data. The printer which has received the print transmitting data generates a private key with a passphrase containing at least printer position information and the held random number by the public key cryptography. The printer then decrypts the received print transmitting data with the private key. Consequently, the security of the print data transmitted from the print client to the printer via a network is ensured.

Abstract: A printer generates a public key dependent on printer position information and transmits it to a print client. The print client encrypts a common key with this public key and transmits it to the printer, and encrypts print data with this common key and transmits it to the printer. The printer generates a private key dependent on printer position information to decrypt the encrypted common key, and decrypts the print data with the common key. Consequently, the printer capable of restricting the place where a print operation can be executed can be provided.

Abstract: The network printer 30 stores print logs generated after a previous log transmission timing into the log storage area 32b, and then sends the print logs stored in the log storage area 32b to the management server 10 at a next log transmission timing. The network printer 30 stores a log relating to a print job into the log storage area 32b on completion of the whole print job when the next job transmission timing does not come before completion of the print job, while storing a log relating to a print job into the log storage area 32b on completion of every one page included in the print job when the next job transmission timing comes before completion of the print job. This arrangement desirably ensures transmission of logs relating to all jobs generated before each transmission timing to the management server.

Abstract: In printing onto a creased paper with a fold portion, a printing method of the invention performs a warning step (S203) that gives a warning about the need of smoothening out of the fold portion; and a printing step that starts printing after the warning is given in the warning step. The printing method further performs a reception step (S204, S206) that receives a confirmation instruction with respect to the warning given in the warning step, and the printing step does not start printing until the confirmation instruction is received in the reception step.
