Abstract: An information transmission system includes a bell, a transmitter, a manual actuator that is manually operated by an operator and actuates the bell, and a controller having a sensor and a memory, wherein the controller analyzes operation information of actuation of the bell actuated by the manual actuator based on an output from the sensor and stores the operation information to the memory, and wherein the transmitter determines operator information corresponding to the operator in the operation information recorded in the memory when the operator rings the bell, and sends the determined operator information.

Abstract: A fastener is configured to fix a pair of opposing flaps of a box in a closed state. The fastener includes a receiving part, a pressing part opposing the receiving part, a linking part interposed between the receiving part and the pressing part, spaces on both sides of the linking part between the receiving part and the pressing part constituting insertion areas into which the flaps of the box are to be inserted, and a cutter part on the receiving part, the pressing part, or the linking part.

Abstract: A bell for a bicycle includes: an attaching tool configured to be attached to a handle of a bicycle; a bell main body directly or indirectly connected to the attaching tool; and a hitting member configured to hit and ring the bell main body, wherein the hitting member is a plate body or a case body and is elastically supported by the bell main body or the attaching tool.

Abstract: A fastener for fixing a pair of opposing flaps of a box in a closed state includes a receiving part extending along a first direction, with a flap abutting part configured to abut surfaces of the flaps being arranged on at least one side of the receiving part, the flap abutting part constituting a tab part for which at least a portion is curvable or bendable upward, a linking part having a rod shape and extending from a center portion of the receiving part, and a pressing part having a rod shaped that extends outwardly from an end of the linking part along the first direction, the pressing part being configured to be inserted into a gap at a juncture of the flaps so that spaces on both sides of the linking part between the receiving part and the pressing part constitute insertion areas into which the flaps are inserted.

Abstract: A desk bell that has a good sound reverb and a long lingering sound includes a swingably supported bell body and striking section that hits the bell body. The striking section includes a striker, an operating part for operating the striker, and separating part that quickly separates the striker from the bell body after the striker striking the bell body. The bell body is placed and supported on or point-supported on a supporting member. The bell body has a conical shape with an open bottom or an inverted bowl shape and has an inner top part placed and supported on or point-supported on the supporting member. The striker is disposed inside the bell body.
