DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a timer device for timer-controlling various functions such as a magnetic recording / reproducing device having a timer-based reservation function.

[0002]

2. Description of the Related Art Recently, there has been a remarkable spread of VTRs, but there is an increasing demand for recording reservation setting, that is, operability of a timer section, as if the rate of the spread was increasing. Therefore, it is no exaggeration to say that the improvement of the operability of the timer unit plays a part in the spread of the VTR.

In a conventional VTR, as shown in FIG. 5, the VTR includes a current time, a recording start time, a recording time, a channel storage unit, a display unit, an input unit, and a comparison circuit for comparing the current time with the recording start time. Was provided within.

In FIG. 5, a is a display unit, b is a channel storage unit, c is a recording time storage unit, d is a recording start time storage unit, e is
Indicates a current time clock section, and their data are input to the input section f.
Can be set freely. The contents of these storage units are compared at the start of comparison g, and the result of the comparison controls the driving of the recording circuit i via the control circuit h.

[0005]

However, according to the conventional method, a fluorescent display tube is turned on as a display,
In addition, current consumption increases to control the recording circuit,
Long-time timer backup is not possible.

In addition, when attempting to set the timer at hand, a conventional timer device cannot form a system well in both the wire remote control and the wireless remote control.

Further, when the power supply to the magnetic recording / reproducing apparatus is temporarily stopped due to a power failure or an accident,
Or result in deviation to the current time, it is that the recording reservation data is put away <br/> disappeared, therefore, not be accurate Timer Recording.

[0008]

In order to solve the above-mentioned problems, a timer device according to the present invention comprises a main body side timer device having at least a current time display section and a current time keeping section; Separated from at least a current time display unit, a current time counting unit, a remote control side timer device having a data input means capable of arbitrarily setting current time data, and at least the current time data of the remote control side timer device. the transmitted to the main body side timer device, by the remote control timer device, a timer device and an arbitrarily settable and data transfer unit the current time of the body side timer device, the data
The data transfer unit checks the data match between multiple data packets.
When the same data is detected more than a predetermined number of times,
The data is made valid .

[0009]

In the timer device according to the present invention, the timer device on the remote control side is separated from the timer device on the main body side, so that there is no need to drive a control circuit, for example, and the display of the timer device on the remote control side is small. Since a power-type display element can be used, power consumption of the timer device on the remote control side can be suppressed. For this reason, a long-term backup by a battery is possible.

Furthermore, since the arbitrarily set the current time it is transmitted to the main body side timer device which is separated the current time data set arbitrarily by the remote control-side timer device at the data transmission unit, when setting it is possible to improve the operability, the wire remote controller for performing a timer setting in the remote control of the timer away from instrumentation Okimoto body can Crossed readily system even when any of the wireless remote control.

Further, due to a power failure or accident, when the power supply to the instrumentation Okimoto body is paused also, it is possible to correct the current time of the main body side timer device by the remote control-side timer device, a timer to the desired time The operation can be performed, and the timer reservation operation can always be performed reliably. Further, the data transmission unit is configured to store a plurality of data.
Data match between data packets, and
Validate the data when it is detected more than a certain number of times
Since it has an error detection function,
Prevents incorrect current time data from being transmitted and always
Accurate from remote control side timer unit to main unit side timer unit
The current time data can be transmitted.
