A terminal unit (201) includes: a casing (204) having a display surface with a display part (205) disposed thereon; a printer head (212) provided inside the casing (204) so as to face the display surface and adapted to print on recording paper pulled out of a recording paper roll (216); and a recording paper roll housing part (222) provided on the side opposite to the display surface across the printer head (212) so as to face the printer head (212). Due to this configuration, the terminal unit (201) can be made compact in the longitudinal direction.

A vacuum insulation material includes: a core member having a large number of minute spaces; a cover member having an internal space in which the core member is housed, the internal pressure being decompression-sealed; and an inspection member provided between the core member and the cover member. The inspection member includes a retaining portion disposed on the core member and a hole formed in the retaining portion.
摘要:
A content protection system prevents illegal key acquisition, without checking uniqueness of device keys. The content protection system includes a key data generation apparatus and a user terminal. The key data generation apparatus converts first key data, which is for using content, based on a predetermined conversion rule, thereby generating second key data, encrypts the second key data using a device key held by valid terminals, and outputs the encrypted key data. The user terminal obtains the encrypted key data, decrypts the encrypted key data using a device key held by the user terminal, thereby generating second key data, converts the second key data based on a re-conversion rule corresponding to the conversion rule, thereby generating the first key data, and uses the content with use of the generated first key data.
