Description

  In the present invention, the information signal of the date and day of the week received by the transmission unit is converted into a radio frequency that can be transmitted by the indoor cable broadcasting facility and transmitted, and the information signal of the date and day of the week is transmitted by the reception unit. The present invention relates to a device that receives and demodulates and displays date and time information on a receiver.

  In any of the conventional methods, only the broadcast frequency, station name, volume, and the like are displayed on the display unit, and there is no one having a date / time or day display function.

Patients admitted to the hospital will wake up on the bed. Usually, a so-called floor head stand is installed beside the bed. This floor head stand is provided with drawers for storing some articles, etc., and a TV is also installed so that patients can watch TV programs for a fee.
Since inpatients live in an environment different from the outside world, it is necessary to check the date and day of the week.
For example, using the time display function of a mobile phone is one means, but there is an inconvenience of picking up and visually checking the mobile phone on the bed each time. There is a way to bring a table clock, but it is often not noticed when hospitalized.
In view of the above, the present invention provides a new and useful means by which the date and day of the week can be easily visually recognized by providing a display function for the date and day of the week on a radio display unit provided in a hospital room. It was invented for the purpose.

The present invention has the following configuration as means for solving the problems.
That is, in an indoor cable broadcasting facility, a time information transmitting device is provided for transmitting date and day information to a receiving device, and the date and day information transmitted from the transmitting device is received and displayed. A wired broadcast receiver is provided, and the above time information transmitter and the indoor wired broadcast receiver are combined. The present invention is a time information wired transmission apparatus configured as described above.

  According to the present invention, in a plurality of receivers installed as indoor cable broadcasting facilities, it is possible to always display the exact date and day of the week without any setting operation, using a clock, a portable terminal, or the like. It is possible to obtain an advantage that the patient on the bed can easily visually recognize the exact date, time and day of the week. Also, unlike the conventional example, it is advantageous in terms of equipment cost for signal transmission by wire.

Reference numeral 7 denotes a level adjuster for adjusting the modulation signal to an appropriate level. Reference numeral 8 denotes an amplifier that amplifies the modulated signal adjusted by the level adjuster to a level necessary for transmission by the indoor cable broadcasting equipment. The modulated signal amplified thereby is not required by the low-pass filter 9. Output after the signal component is attenuated.
The above is the configuration of the transmission unit.

  FIG. 2 shows a receiving unit. The signal branched from the indoor cable broadcasting transmission line (modulated signal output) is divided into two by 20 distributors, FM broadcast band signals are selected by 21 band filters, and 22 wired FM broadcast receivers are selected. The demodulated sound is output, and broadcast information such as the broadcast station name and frequency is displayed on the display 23. The other distributed signal selects and passes only the time information modulated wave signal by the bandpass filter 24, and attenuates other signals superimposed on the indoor cable broadcasting transmission line. The time information modulated wave signal selected by the bandpass filter is amplified to a required level by 25 amplifiers, demodulated by 26 amplitude demodulators, and then the original time information digital signal by 27 signal discriminators. Restore to. The signal is processed by the signal processing unit 28, and the date and day of the week are displayed on the display 23.

FIG. 3 shows a transmitter, and FIG. 4 shows a receiver. In FIG. 3, 1 to 4 are the same as those in the above embodiment. Reference numeral 30 denotes a frequency modulator that modulates a carrier signal that can be transmitted by the indoor cable broadcasting transmission system with the digital information signal of the date and day of the week and the day of the week.
31 to 33 are the same as the previous example, 31 is a level adjuster, 32 is an amplifier, and 33 is a low-pass filter. In addition, it is good also as a phase modulation system using a phase modulator for 31. FIG.
