Abstract: A quick board with a handle to operate the driving power of a front wheel is used for leisure, taste and amusement activities of teenagers, adults, children and others. In the quick board according to the present invention, the driving power to drive a front wheel is operated by only a handle of the quick board, thereby strengthening the muscular strength of the arms and waist of a user and minimizing the components of the quick board to avoid the complicated configuration in appearance. When a child who has a difficulty in pivoting a driving frame forward and backward operatively connected to a handle part to drive the front wheel uses a quick board, a front wheel cover part of a main body frame and the driving frame are selectively fixed so that such a user can enjoy the quick board in a stable and safe state.

Abstract: A video playing apparatus and a method of adjusting a sound volume of the video playing apparatus are provided. The video playing apparatus can adjust the volume if a predetermined key is input continuously.

Abstract: A display apparatus and a channel information displaying method thereof are provided. The channel information displaying method of a display apparatus having a channel storage unit for storing channel identification information and channel receipt information about a plurality of channels includes: determining whether a new channel is received in addition to the plurality of channels, based on the channel identification information and the channel receipt information stored in the channel storage unit; storing the channel identification information and the channel receipt information about the new channel in the channel storage unit when the new channel is received; and displaying an indication indicating that the new channel is added and the channel identification information. With this configruation, a user may recognize whether a channel is added and which channel is added.

Abstract: A device for detecting cut of a tape generates a cut signal of a tape by using a pulse generating portion and a light signal generating portion when a number of pulses per second generated by the rotation of a detecting gear is larger than the maximum number of pulses per second during normal operation. A first gear is rotated by a rotation driving part in forward play operation mode of a tape. A second gear is rotated by the rotation driving part in reverse play operation mode of the tape. A detecting gear of a detecting gear portion is engaged with the first gear or the second gear according to the operation mode. A pulse generating portion generates pulses corresponding to a speed of revolution of the detecting gear and a light signal generating and pulse detecting portion detects the generated pulses. A microprocessor decides the revolution state of the engaged gear from the number of detected pulses per second.
