Abstract
A pedal controller of a television broadcasting prompter comprises a control box, an electronic circuit and a pedal switch. The electronic circuit is mounted in the control box, the pedal switch is connected with the electronic circuit via four-core cable, and an outer cable is connected with a computer of the television broadcasting prompter and the electronic circuit. The pedal switch comprises a switch body, a pivot base fixed on the switch body, a pivot mounted in the pivot shaft, a pedal cover sleeved on the pivot via a shaft hole, a resetting spring mounted between the switch body and the pedal cover and a microswitch mounted in the switch body, and the four-core cable is connected with the microswitch. The end of the outer cable is connected with a USB interface. The pedal controller can be controlled via feet, is simple in operation and reliable in control, can prevent announcers from claiming attention, reduces work load, is low in noise, can not affect broadcasting effect, and can be widely popularized and applied to various television broadcasting prompters.
Description
Technical field
The utility model relates to the radio and television equipment, more particularly relates to the improvement of the foot controller of tv announcing prompter device.
Background technology
Traditional tv announcing prompter device is a camera head type, and moving of prompter content manually controlled by the announcer, and contribution need the original text plate moves up and down or manual page turning along pushing away, and operation easier is big, and announcer's burden is heavy.
Along with development of computer, increasing tv announcing prompter device adopts computing machine typing, editor's broadcast manuscript.During broadcast, realizations such as trace ball that announcer operation links to each other with computing machine or handle to the broadcast of manuscript, stop and broadcasting speed is controlled.These control modes all are manual operations without exception, and the limitation of use is big, easily entanglement under some occasion.Therefore, this mode of operation easily makes the announcer divert one's attention, and also just is not subjected to announcer's welcome.
In addition, the operating noise of traditional tv broadcast prompter device is bigger, and effect is broadcasted in influence.
The announcer is badly in need of tv announcing prompter device a kind of novelty, that do not need or seldom use manual control in this case.
Summary of the invention
The purpose of this utility model just is to overcome above-mentioned shortcoming and defect, and a kind of foot controller of improved tv announcing prompter device is provided.Its available foot control system, simple to operate, control is reliable, the work load of diverting one's attention, alleviate the announcer in the time of avoiding the announcer to broadcast; And noise is low, does not influence the broadcast effect.Thereby be subjected to most of announcers' welcome, but wide popularization and application.
In order to achieve the above object, the utility model foot-switch of comprising control enclosure, be installed in electronic circuit in the control enclosure, being connected with electronic circuit with 4 core cables.Outer cable is connected with electronic circuit with the computing machine of tv announcing prompter device.
Foot-switch comprises switch body, be fixed on pivotal block on the switch body, be installed in pivot in the pivotal block, with the pivoted foot-operated lid of shaft hole sleeve, be installed in the back-moving spring between switch body and the foot-operated lid and be installed in microswitch in the switch body.4 core cables are connected with microswitch.
The end of outer cable is connecting USB interface, and USB interface is connected with the USB mouth of computing machine.It is very convenient quick that USB interface connects computing machine, and reliable.
The utility model can be used foot control system, and is simple to operate, and control is reliable, the work load of diverting one's attention, alleviate the announcer in the time of avoiding the announcer to broadcast; And noise is low, does not influence the broadcast effect.Thereby be subjected to most of announcers' welcome.But wide popularization and application is in various tv announcing prompter devices.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Embodiment 1.A kind of foot controller of tv announcing prompter device, as shown in Figure 1.The foot-switch 3 that it comprises control enclosure 1, be installed in electronic circuit 2 in the control enclosure 1, be connected with electronic circuit 2 with 4 core cables 11.Outer cable 5 is connected with electronic circuit 2 with the computing machine of tv announcing prompter device.
Foot-switch 3 comprises switch body 4, be fixed on pivotal block 5 on the switch body 4, be installed in pivot 6 in the pivotal block 5, be sleeved on foot-operated lid 8 on the pivot 6, be installed in switch body 4 and foot-operatedly cover the back-moving spring 9 between 8 and be installed in microswitch 10 in the switch body 4 with axis hole 7.4 core cables 11 are connected with microswitch 10.
The end of outer cable 5 is connecting usb 12, and usb 12 is connected with the USB mouth of computing machine.It is very convenient quick that usb 12 connects computing machine, and reliable.
During work, the foot-switch 3 that foot-operated band resets certainly, the microswitch 10 triggering for generating corresponding electric signal in it.This electric signal reaches computing machine through outer cable 5 and usb 12, again through software control manuscript operation/time-out after the electronic circuit 2 of control enclosure 1 inside is handled.Do not produce electric signal during foot-switch 3 attonitys, electronic circuit 2 does not respond, and maintains laststate and do response again when detecting next operation.The response of the microswitch 10 in the control enclosure 1 is short triggering, steps on foot-switch 3 operation of switching manuscripts and time-outs, whenever steps on one of a secondary response and triggers switching one next state, and it is invalid that length is stepped on.Each announcer can meet the broadcast speed that oneself requires by software setting, has adjusted speed after, the announcer fully can be only controls by this foot-switch 3 prompters that realize broadcasting.
Embodiment 1 can use foot control system, and is simple to operate, and control is reliable, the work load of diverting one's attention, alleviate the announcer in the time of avoiding the announcer to broadcast; And noise is low, does not influence the broadcast effect.Thereby be subjected to most of announcers' welcome.But wide popularization and application is in various tv announcing prompter devices.
