Description

DETAILED DESCRIPTION OF THE INVENTION The present application provides a control element on a time management tape started by a timer, and the control element controls BGM.
The present invention relates to a time management device configured to indirectly control the drive of a (BackGroundMuslc) tape.

Today, in companies, factories, banks, etc., time management tapes and BGM tapes are used instead of bells and buzzers to announce the start, end, break, or closing times of the day. Many methods are used.

However, according to the conventional time management system, both the drive stop of the time management tape that announces the start time etc. by the time announcement signal and the drive stop of the BGM tape that is played during a certain time period are required respectively. Since the configuration is controlled by a dedicated timer, two timer circuits are required, which makes the device expensive, and there are also problems with the control timing of both drive circuits.

Therefore, the present application has been made to improve the above-mentioned defects, and an embodiment thereof will be described in detail below with reference to the drawings. The former performance circuit A
includes a playback head 1, a playback amplifier 2, a rectifier circuit 3,
For example, as shown in Fig. 2, notification signals a, , a, . . . are recorded on a tape to notify the start time, etc.
Stop position signals b, , b provided respectively at the rear of ...
.

, . . . is started by a transistor circuit 4 that generates a stop signal when the reproducing head 1 detects , and start signals Cl, Co, . . . from a timer 5, a regeneration circuit 7 comprising a drive circuit 6 that stops driving in response to a stop signal from the transistor circuit 4;
As shown in FIG.
A control signal circuit 9 is provided which has a contactor 8 that comes into contact with dl, d2, etc. and outputs a control signal upon contact with the control signal circuit 9. A flip-flop circuit 10 which is inverted in operation by a control signal from 9, and a BGM tape drive circuit 11 whose drive is controlled by this flip-flop circuit 10 are provided. 12 and 13 are control signal connection terminals, R1
And R2 indicates a relay provided in the drive circuits 6 and 11, respectively.

But now, the time announcements are 7 o'clock, 7 o'clock 4 minutes, 8 o'clock, 8 o'clock.
At 5 o'clock, 1 o'clock, 1 (g) 3 o'clock, 1 at 11 o'clock, 1 o'clock...
Performed with comments or music for 1 minute to 1 hour, and B
Regarding the case where GM is broadcast in different time slots, such as from 7:10 to 7:50, from 8:01 gin to 9:03 gin, from l(t) 3 gin to 1 man, etc. To explain, as shown in FIG. 2, the time management tape includes notification signals Al, a2, . . . to be broadcast at respective times, and stop position signals Bl, b2, . - are recorded, and correspond to 7:01 gin, 7:5 gin, 8:0 m, 9:3 gin, Samurai (9) minutes, 1 man, etc. on this tape. Silver contacts Dl, d2, . . . as control elements are placed at the positions of
is provided by pasting or the like, and the time management tape thus constructed is set in the time management performance circuit A. In this state, the start signal C from the timer 5
When the 1 or 7 o'clock position is input to the drive circuit 6, the signal starts the drive circuit 6 and the time tube . As the medical tape runs, an announcement signal a1 is reproduced, for example, announcing the start time, and this announcement is stopped by the stop position signal Kg.

On the other hand, when the control element d1 corresponding to the 7 o'clock position located immediately before the stop position signal B comes into contact with the contact 8, the control element d1, which is located immediately before the stop position signal B, contacts the contact 8. The control signal is sent to the flip-flop circuit 10 via the circuit 9.
, the circuit is inverted to 0N, the drive circuit 11 of the BGM performance circuit B is started, and BGM performance is performed.
This BGM performance is stopped by inputting a control signal to the flip-flop circuit 10 due to the contact between the control element ↓ corresponding to 7:50 and the contact 8, and inverting the circuit 10 to 0FF. However, during this BGM playing, the drive circuit 6 of the time management performance circuit A is started again by the second start signal from the timer 5, that is, the 7:04 start signal C2, and the second notification signal A2 is broadcast. be done.
In this way, the time management tape drive circuit J6
Regardless of the BGM tape, it is started at preset regular times by a start signal from a dedicated timer 5, and its stop is caused by a stop position signal B on the tape.
On the other hand, the drive of the system tape is automatically controlled by a control element set in advance on the time management tape.

As described above, according to the present application, since only one control timer circuit is required, an inexpensive device can be provided, and
It is extremely advantageous to be able to use another conventionally used timer circuit, for example, for the power supply control of the broadcasting system or other control circuits, and the control timing of both performance circuits can also be controlled well. In particular, according to the present application, since the control element can be selectively provided on the time management tape, the playback time of the BGM tape can be arbitrarily selected without being restricted by the time management contents. It has the following advantages.
