Abstract: Eye training equipment, wherein at least two irritation generating devices for perceiving irritating positions are disposed around an eye ball, and the disposed irritation generating devices are operated one by one to allow the line of sight of a user to follow up in the direction of the irritating position, whereby, since merely the line of sight of the user is allowed to follow up in the direction of the irritating position, the user of the training equipment can perform an eye muscle motion without requiring the need for specifically viewing an object by opening an eye.

Abstract: Disclosed is an automatic roll paper feeder that has no switch on its face to be operated by a user and includes a sensor that reads the user starting or ceasing to pull out paper from the roll by monitoring movement of the paper. A signal from the sensor triggers a control program and causes the feeder to automatically cut and dispense the paper under the control program, thus eliminating the need for a user to act on any switch to operate the feeder. The feeder through movement of paper can read out the user's will precisely. The invention enables a handicapped user (e. g., one-armed, blind, aged or very young) to easily pull out and sever paper with one hand from a paper roll such as a toilet paper, cooking paper or paper towel in the form of a roll.

Abstract: This invention relates to a device for shooting bullets by pressure medium for use in a toy gun. This mechanism includes a piston member fitted into an outer tubular member and reciprocating in response to changes in the pressure medium, and wait hook arms are provided in the piston member. Further, an inner tubular body having a gas injection hole is fixedly provided within the outer tubular member, and a needle valve for opening and closing the injection hole is provided in association with the inner tubular body. This needle valve is provided with a weight biased by a spring member. The weight is disengaged from the wait hook arm by the advancing movement of the piston member and hits against the rear end portion of the needle valve. In addition, at the rear end portion of the needle valve, there is provided a seal valve for temporarily closing a gas introduction hole provided on the side of the rear end portion of the outer tubular member by hitting of the weight.
