Abstract: An electronic storage box, an electronic storage box opening and closing method, and computer program product, comprising: safety, portability, convenience, economical efficiency and presentation effects are provided. In case a cryptograph setting request signal is received from a PC 21, the electronic storage box 1 stores cryptograph information included in the cryptograph setting request signal. In case an opening and closing request signal is received from a PC 21, the electronic storage box 1 determines whether or not the cryptograph information included in the opening and closing request signal and the cryptograph information stored in a key storage portion 103 match with each other. In case it is determined that these pieces of the cryptograph information match with each other, the electronic storage box 1 allows a lid 12 to shift either to an opened state or a closed state according to the opening and closing state of the lid 12.

Abstract: A CRT display device on which an input signal which has been processed can form an image signal which results in an image being displayed. The CRT display device has a separate message section which can be a dot matrix display. On this separate message section there is a display where displayed messages indicative of the input signal. The message display section displays messages related to the input signal even when there is no image on the cathode ray tube of the CRT display device so that a user based on these messages can input parameters to provide an image on the CRT. The messages on the display device can be shown in various languages.
