Abstract: The present invention discloses a timer capable of sounding a prescribed time and further capable of functioning as a calendar, a watch or a thermometer frequently used every day life by a simple method.A hollow main body (1) is constituted by a plurality of square or rectangular side plates (3) with the same pattern connected to each other so as to form a polygonal cube frame and lids (4, 4a, 4b) having a configuration corresponding to that of the upper and lower openings of the polygonal cube frame. A pair of ON-contacts (5, 5) each in the shape of a stick are mounted at each inner surface of a time setting device (2) containing a spherical conductor (6) displaced within the frame with a reduced and almost the same pattern a that of the frame along with a connecting portion of a side plate (7). Thus, the timer is constituted in a manner such that the side plate (7) of the frame and time setting device are parallel each other.

Abstract: A hollow main body(1) is constituted by a plurality of square or rectangular side plates(3) with the same pattern connected to each other so as to form a polygonal cube frame and lids(4,4a,4b) having a configuration corresponding to that of the upper and lower openings of said polygonal cube frame. Two ON-contacts(5,5) in the shape of a stick are mounted at each inner surface of a time setting device(2) containing a spherical conductor(6) displaced within the frame with the reduced and almost the same pattern with that of said frame along with a connecting portion (8). Thus, the timer is constituted in a manner that the side plates of said frame and time setting device are parallel each other. A preliminarily prescribed setting time(9) is indicated on the outer surface of said hollow main body(1).

Abstract: An electronic calculator is provided with an abacus and has both advantages of the calculator and abacus. An abacus and a portable electronic calculator are integrally constituted in such a manner as superimposing each other. Thus, the calculator according to the present invention can be used as a abacus by shifting a counter of an abacus along a guide bar thereof and it can also be used as a conventional electronic calculator by pushing the counter downward.

Abstract: The present invention discloses a receptacle for receiving a small article. The receptacle for receiving a small article comprises a receptacle body, a cover and a closing operation plate made of plastics each which is independently and integrally formed by injection molding so as to constitute the receptacle by assembling these constitutional members.According to the receptacle for receiving a small article of the present invention, there is no danger of loosening the connecting portion of the receptacle body and the cover or no danger of loosening a locking condition of the cover. Further unlocking action may easily be carried out.
