Title: Keyboard device for input of japanese word with small number of keys
Inventor: MATSUMOTO KEITA
IPC: H03M11/08
Filed: 1990-10-01
Abstract: PURPOSE:To obtain a compact keyboard with which the Japanese words can be easily inputted even with a single hand with a simple operation by inputting some characters with the simultaneous push of two keys contiguous to each other. CONSTITUTION:The marks A and B are horizontally provided on the surface of a key 1 together with a mark C given to a key 2 respectively. When the key 1 or 2 is singularly pushed, a character A or C is produced. Then a character B is obtained when both keys 1 and 2 are pushed at one time. Thus three characters A, B and C are obtained with use of two keys 1 and 2. As a result, the number of keys is decreased and therefore the size of a keyboard can be reduced. Furthermore the single-hand operability of the keyboard is improved.

Abstract: PURPOSE:To enable only a suction port cover to be easily fitted or removed by a method wherein the suction port cover is independently supported at a member forming a peripheral edge of the suction port without any relation with other members in such a way as it may be fitted or removed freely. CONSTITUTION:Air passed through aeration holes 33 and sucked into an air duct 32 from a suction port 13 under an operation of a blower 27 is cooled by an evaporator 26 to become a cold air, the cold air is blown from a blowing port 12 so as to form an air curtain covering an opening 2 and at the same time the air cools inside a case 1, sucked again at the suction port 13 so as to form a circulating flow 28. Commodities placed on shelves 19 and display shelves 25 within the case 1 are cooled by this circulating flow 28. In turn, since a suction port cover 34 is not integral with a member constituting a partition wall 29, for example, a guard 31 or the like, the suction port cover 34 can be fixed or removed only with an insertion or removal of a hook-shaped front end into or from a groove 17 without any relation with other members and then the suction port cover 34 is made small and light in its weight. Due to this fact, a cleaning operation within the suction port 13 and around its peripheral part becomes easy.
