Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a recorded information playback device commonly known as a karaoke device, and is based on a multi-operation system using an autochanger, which is particularly popular in the service industry. Sexy in other fields as well! This is effective when applied to equipment that transmits instruction information for each button.

2. Description of the Related Art Conventional playback devices of this type range from simple types in which the user selects a recording cassette, etc., to be taken out of the stocker and placed in the playback device, to automatic playback devices in which the user selects a recording cassette, etc., from the stocker and sets it in the playback device, or automatically selects a specified track by inputting an instruction such as by operating a button. Various types of playback devices have been provided, ranging from autochanger types that select a recording medium and start playback.

On the other hand, in recent years, in order to improve services at inns and banquet facilities, the above-mentioned recycling equipment has been increasingly deployed, but conventional deployment of this type involves installing a set of recycling equipment at each usage location. there were.

Moreover, recently, the installation of such playback devices has come to be required in each room of hotels and the like.

Problems to be Solved by the Invention By the way, since the playback device is installed in a guest room and is used by unspecified users in a single room, it is difficult to avoid unexpected accidents such as damage or loss of cassettes or discs. When considering preventive measures and operational convenience, it is preferable to use an autochanger type equipment with internal discs. In addition to the inconvenience of the arrangement, it is not economical to deploy such a device in each room when considering the utilization rate of each room.

Therefore, the present invention improves utilization efficiency by installing the playback mechanism section of the main part of the device at a centralized management location such as a hotel front desk, and installing the display section of the device as a terminal mechanism at each usage location such as a guest room. , provides an apparatus configuration that can solve each of the above-mentioned problems all at once.

Means for Solving the Problems According to the present invention, the present invention provides a central control mechanism whose main part is a comprehensive automatic playback device having a stocker for recording media such as disks, and a specified amount of information to be read. By separating the peripheral terminal mechanism whose main part is the display device and connecting them by wire, there is an instruction signal output stage in which the desired recording information is determined by a selection instruction operation in the peripheral terminal mechanism, and a central Based on the instruction signal in the control mechanism, there is a channel designation stage in which a high frequency output channel for transmitting designated information is directed to a peripheral terminal mechanism, and a channel switching operation is performed in the peripheral terminal mechanism that receives the channel designation signal, and then the display device of the mechanism is This can be achieved by a recording/playback system comprising a readout step for displaying the designated information.

In addition, as a device configuration for this purpose, an automatic playback device is equipped with a large number of information recording media recorded using magnetic storage tape cassettes or optical records (FI disks, etc.) as storage media, and is configured to be able to selectively reproduce them. A central control mechanism in which #i unit mechanisms consisting of RF converters and input/output control devices are arranged in parallel, outputs a selection instruction signal to a display device consisting of a television receiver and the control device, and A peripheral terminal mechanism comprising an input/output control device equipped with an interface mechanism for receiving an output channel designation signal from the control device is connected to the central control device through a channel selector mechanism that searches for a standby unit mechanism. We propose a recording and playback device that is

Operation According to the above playback system, a readout signal of recorded information specified by keyboard operation or switch button operation in the first peripheral instruction mechanism is immediately transmitted to the central control mechanism through the communication line, and the specified information in the central control mechanism is immediately transmitted to the central control mechanism through the communication line. When the information is searched and a record of the relevant information is found, the readout information transmission channel is simultaneously instructed to the peripheral terminal mechanism.

The peripheral terminal device that has received the channel designation sets the reception channel of the display device to the designated channel. In anticipation of the time lag required for channel setting on the peripheral terminal mechanism side, or by receiving a feedback signal of the setting operation.

The automatic playback device of the central control mechanism starts reading information, so that the display device displays the instructed information.

In the device configuration for this purpose, signal transmission and reception between these re-mechanisms is performed in accordance with a predetermined control program via an input/output control device disposed in each mechanism.

The plurality of unit mechanisms modulate the information signals that they individually read into high frequency signals each having a unique frequency, and an RF converter functions for this modulation.

In addition, the multiple unit mechanisms were installed to support simultaneous use by multiple peripheral terminal mechanisms.
When a plurality of these terminal mechanisms are used simultaneously, a channel selector mechanism interposed in the communication line connecting these peripheral terminal mechanisms and the central control mechanism searches for and selects the unit mechanism that is on standby. The peripheral terminal units that are outputting instruction signals are connected in sequence.

This VC connection between a specific unit mechanism and a specific peripheral terminal mechanism determines a unique transmission frequency, that is, a channel, in the unit mechanism, and the peripheral terminal mechanism is informed of the channel determination.

Therefore, the peripheral terminal mechanism can receive signals by setting the display capacity to a designated channel, and a television receiver can be used as the display device for this purpose.
