Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention provides a foul display device for basketball games;
In particular, it relates to a foul display device for basketball games that is capable of displaying a display according to the seven foul rule, which allows up to seven fouls as a team foul, and a display according to the five foul rule, which allows up to five fouls as an individual foul, on one display device. .

<Prior Art> A conventional foul display device for basketball games of this type is disclosed in, for example, Japanese Utility Model Application Publication No. 57-136372. This device has one five-foul indicator light and two seven-foul indicator lights, one for each team, mounted on a base.

<Problems to be solved by the invention> Normally, in basketball games, an official table is placed near the center line of the court, and there is one person in charge of the timer who measures the playing time, one person in charge of the score display, and one person in charge of the score display. Two foul display staff will be assigned to each team to count and display fouls. Since a score display board, a foul display board, a score note, etc. are placed on the official table, there is a problem in that the space for placing each item is limited. Furthermore, with the seven-foul indicator light that lights up only when the team has committed seven fouls, as seen in the prior art mentioned above, it is difficult for the players to know how many fouls have been committed until the seven fouls have been committed. There is also the problem that it is inconvenient for the audience.

The present invention has been made in view of the following circumstances: 1.
To provide a foul display device for a basketball game, which can display seven fouls and five fouls on one display device, and can also display the number of times of both seven fouls and five fouls.

Means for Solving the Problems> The foul display device for basketball games according to the present invention includes a rotary switch having at least seven switching positions corresponding to seven fouls in basketball games; A key switch group consisting of a fifth key switch, a signal conversion circuit that converts each of the five signals from the key switch group into a pulse signal, and a display unit consisting of at least seven stages of display bodies, the display section comprising a display unit having at least seven stages, and a display section comprising a display unit with at least seven stages, and a display section comprising a display unit with at least seven stages, and a display section comprising a display unit with at least seven stages, and a display section comprising a display unit with at least seven stages. The seven foul signal drives the display of the corresponding stage, and the first
or any of the first to fifth key switches, wherein when the fifth key switch is operated, the display unit of the corresponding stage is driven to blink by a key switch signal pulsed through the signal conversion circuit; The present invention includes a prohibition circuit that prohibits input of the seven foul signal outputted from the rotary switch to the display section only when such a signal is present.

<Function> When the rotary switch is set, for example, to the third stage, the third stage signal is applied to the first, second and third display bodies to put them in a display state. This resulted in a team foul of “3”.
is displayed. This display is performed continuously. In this seven foul display state, when the second key switch of the personal foul key is operated, for example in response to the second foul, the second key switch signal is generated only during the operation period, and this signal activates the prohibition circuit. , the first, second and third display bodies in the seven foul display state are turned off. At the same time, the second key switch signal is pulsed by the signal conversion circuit to intermittently drive the second display. As a result, the second display body blinks and displays the number of personal fouls "2". After that, when the operator releases his/her finger from the second key switch, the blinking display on the second display disappears, and the first, second, and third displays turn on continuously again, returning to seven-foul-like deafness.
